Subject: [PATCH 01/87] test(skills-embed): add failing gate for the
 configure-time embed step

This gate verifies that:
- generated/embedded_skills.h exists after configure
- all skills/ and hooks/ files appear in the header
- the header is byte-identical across two configures (determinism)
- CMAKE_CONFIGURE_DEPENDS triggers on skill file changes

Expected to fail until the CMake embed step is implemented.

Subject: [PATCH 03/87] test(skills-embed): extend selfcontainedcheck gate with
 embedded_skills verification

Adds four new arms to the existing selfcontainedcheck.sh gate, following the
established pattern for embedded_queries.h:

1. Source-tree path check: verify binary contains no literal skills/ or hooks/ paths
2. Compiled probe + cross-check: C++ probe reads embedded_skills.h interfaces and
   validates against real source-tree files (byte-exact match, no missing/extra entries)
3. Isolated-binary test: verify 'ripwire skills install' doesn't fail with source-tree
   complaints (currently fails as expected for unimplemented subcommand)

The gate currently fails on missing generated/embedded_skills.h (expected red state
until CMake embed step is implemented in a later task). Once that task lands, this
gate will automatically pass all arms.

Subject: [PATCH 04/87] feat(cmake): embed skills/ and hooks/ into a generated
 header at configure time
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- adds a _ripwire_embedded_skills block after _ripwire_embedded_queries,
  modeled on it, producing generated/embedded_skills.h with
  rw::embedded_skills::{EmbeddedFile, kSkillFiles, kHookFiles, kVersion,
  kHash8, kStoreKey}
- CONFIGURE_DEPENDS added directly to both file(GLOB_RECURSE...) and
  file(GLOB...) calls so an added/removed skill or hook file triggers a
  reconfigure, not just edits to already-tracked files
- diverges from the plan brief's literal snippet in two ways forced by
  Task 1's selfcontainedcheck.sh gate (the actual contract):
    * stored relative paths are prefixed with skills/ or hooks/ (the gate
      compares against paths relative to $ROOT, not to skills/ or hooks/)
    * skills/*.md at the top level (e.g. skills/CONSOLIDATION.md) is
      filtered out — only files inside a skills/<name>/ subdirectory are
      embedded, matching the gate's skills/*/ + rglob walk
  also fixed \x1e (not a valid CMake string escape) to a record separator
  built via string(ASCII 30 ...)
- registers embedded_skills.h in ripwirepubliccheck.sh's generated-header
  allowlist

test/selfcontainedcheck.sh's new skills/hooks arms now pass.

Subject: [PATCH 05/87] docs(cmake): flag the *.md-only glob's coupling to
 today's tree

Review finding: the glob at _ripwire_skill_files only matches .md files,
while test/selfcontainedcheck.sh's byte-exact cross-check walks every
file under skills/*/ with no extension filter. They agree today only
because every file under every skills/<name>/ subdirectory happens to be
markdown. Add a comment directly on the glob line so a future contributor
adding a non-.md companion file sees the coupling at the point that would
break, not buried in a report file.

Comment-only change; bash test/selfcontainedcheck.sh re-run unaffected.

Subject: [PATCH 06/87] test(skills-install): add gate for ripwire skills
 install extraction and link-safety

Creates test/skillsinstallcheck.sh with three arms to verify the (not-yet-implemented)
ripwire skills install subcommand:

- Arm 1 (fresh install): verifies skills directory creation, .ripwire-manifest-v2 file with
  version=2 and source= fields, and symlinks to ripwire-* skills
- Arm 2 (idempotency): confirms store directory is not re-extracted on a second run
- Arm 3 (link-safety): ensures the command refuses to write through a pre-planted symlink
  at the destination

Registers the gate in test/regression.sh's absorb loop (now 619 gates, up from 618).

Expected state: gate fails at arm 1 with 'ripwire: unknown command skills' or similar,
since the subcommand does not yet exist. Later tasks (4, 6, 8, 10, 12) will append
additional arms to verify implementation details as they are built.

Subject: [PATCH 07/87] build(gate-manifest): update gate count and add
 pargates weight for skillsinstallcheck

- Ran docs/gatecount_build.py to update gate count from 618 to 619 in all marked sites
  (docs/EVALS.md, README.md, present/deck5_ripwire_build.js)
- Added skillsinstallcheck.sh weight entry (2.2) to .github/pargates-shard-weights.json
  in correct alphabetical position

Gate count now reflects the new test/skillsinstallcheck.sh gate added in previous commit.

Subject: [PATCH 08/87] fix(skills-install gate): honor RIPWIRE_BIN env var for
 binary override

Changed line 6 from hardcoded ./build/ripwire path to match the standard pattern:
  ripwire="${1:-${RIPWIRE_BIN:-$ROOT/build/ripwire}}"

Added repo-relative path guard to convert relative paths to absolute by prefixing $ROOT,
following the pattern established by test/skillscanreadcheck.sh.

This ensures the gate respects RIPWIRE_BIN environment variable set by test/regression.sh
and test/pargates.py, enabling binary override for G1 ASAN verification and CI shard testing.

Verified: gate still correctly fails at arm 1 (subcommand not yet implemented).

Subject: [PATCH 09/87] feat(skills-install): store extraction, link-safe
 symlinking, claude-default dispatch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements `ripwire skills install` per the task-4 brief, with three amendments
folded in: bare "embedded_skills.h" include (the generated dir is already an
include path), rw::pathguard::isSymlink/openNoFollowTruncate reused instead of
ad hoc lstat/S_ISLNK checks, and every OS-differing call grouped into named
helpers (symlinkOrRefuse, renameAtomic) ahead of src/infra/os.h landing.

Two deviations from the brief's illustrative snippet, both required to make
the already-committed gate (test/skillsinstallcheck.sh, task 3) pass:

- The embedded relativePath carries CMake's "skills/" group prefix
  (skills/<name>/SKILL.md), so the brief's `*rel.begin()` would have collapsed
  every skill into one link literally named "skills". Fixed to read the
  second path component instead.
- Arm 1 greps for a `.ripwire-manifest-v2` sidecar (version=2, source=) that
  the brief's runSkillsInstall snippet never writes. Added a minimal write of
  just those two fields, through pathguard's openNoFollowTruncate (this
  sidecar is rewritten on every install, unlike the O_EXCL store extraction).
  The richer manifest (per-agent entries, prune inventory) stays Task 8's scope.

Also filters the link loop to the "ripwire-*" name scope skills/install.sh's
own Claude-mode loop uses, so skills/hermes/ (Hermes-native, --hermes-only)
is never linked under the bare "hermes" name into a Claude skills directory.

test/skillsinstallcheck.sh: fixed a subshell-scoping bug in sandbox() —
`d1="$( sandbox )"` forked a subshell, so sandbox()'s exports never reached
the parent shell and every arm ran against the real $HOME/$CLAUDE_CONFIG_DIR
instead of the sandbox. No arm's assertions changed, only the calling
convention (`sandbox; d1="$d"`).

Subject: [PATCH 10/87] fix(gateexitcheck): pin skillsinstallcheck.sh in
 FAILFAST
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

skillsinstallcheck.sh's fail() prints and exits 1 directly at each arm, with
no accumulator variable, so gateexitcheck.sh's sweep correctly flags it as
unclassified without a FAILFAST pin. Forced a real failure (fake ripwire
binary lacking the skills subcommand) and confirmed rc=1 before pinning it —
per the file's own rule that every row is run, not read from the exit
literal.

Four std::filesystem calls in src/skillsinstall.h used throwing overloads
instead of the error_code& overload the rest of the file already uses
(extractGroup's exists/create_directories calls), violating the plan's
"no exceptions, failures returned by value" constraint:

- writeStoreFile's create_directories( dest.parent_path() )
- linkOrRefuse's create_directories( destLink.parent_path() )
- runSkillsInstall's create_directories( skillsDest )
- the exists( symlink_status( destLink ) ) pair in runSkillsInstall's link loop

All four now take an error_code and turn a failure into an Outcome{false,...}
(the two Outcome-returning functions) or an emitted error + non-zero exit
(runSkillsInstall, which returns int).

symlink_status's error_code overload needed one more fix once switched over:
libc++ sets ec=ENOENT for a plain "nothing there" (the ordinary first-install
case), unlike the letter of the standard — confirmed empirically, not assumed
from a doc read. That specific errc is treated as "does not exist" and the
loop proceeds to link; any other ec is treated as a real failure and that
skill is skipped rather than risk writing under an unverifiable destination
state.

Verified: bash test/skillsinstallcheck.sh ./build/ripwire still passes arms
1-3, and a manual run still links exactly 17 ripwire-* skills.

Subject: [PATCH 14/87] feat(skills-install): manifest v2 read/write and
 link-safe pruning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends writeManifestV2 to record one skill= line per currently-linked
skill, adds readManifestV2 to parse the sidecar back (via pathguard's
openNoFollowRead, matching the write side's openNoFollowTruncate), and
adds pruneStale to unlink destination entries the previous manifest
tracked that are no longer current. unlink() never follows a symlink at
the final path component, so pruning a planted link removes the entry
without touching its target; pruneStale also refuses any manifest-read
name containing "/", ".", or ".." before joining it to destDir, since
that name comes from a user-writable sidecar. runSkillsInstall now
reads the previous manifest before linking, prunes what's gone, links
what's current, and writes the updated manifest — making
test/skillsinstallcheck.sh's arms 4-5 (added in the prior commit) pass.

 ack api-surface ebaa8de80f3b5caa 2 cid=fbf73430469857ac A3 (review of #219), the other half of the TestRunnerIndex ack above: runHintClauseIfRows takes the root-relative predicate as well as the row count, because the clause's ROOT-RELATIVE sentence must answer to the same fact that spells run= itself — a multi-root run declares no root= and correctly keeps an absolute command, so a clause claiming relativity there is a wrong answer, not a cosmetic one. The parameter is the fix and there is deliberately no default: a defaulted false would let a caller silently drop the sentence, which is the silent-wrong-answer shape this lane exists to remove. All ten call sites pass the predicate they already hold (packtask, flipimpact, handoff, partition, prcontext x2, verbs_change x2, situ, testmap). Visible only now because #214 landed the one-parameter form onto main first; once this lane merges, main carries the two-parameter form and the row cannot recur. Proven by runhintcheck 2c/2d (the root-spelling matrix, and multi-root does not claim a relativity it does not have) and prcontextcheck 49 rows, full suite gates=629 pass=627 skip=2 fail=0.
 ack api-surface ed05ee0357d016f1 4 --lint reads the corpus ONCE (audit lane B2, second half): astQueryGrouped gains an OPT-IN keptBytesOut, so the walk that already reads every file hands its bytes to the two symbol-level passes that ran after it instead of each re-opening the same ~900 files one at a time on the main thread. The +1 param on astQueryGrouped/namingLensChecks/appendNamingFindings is that deliberate contract and it is DEFAULTED — the --ensemble caller passes nothing and is byte-identical, verified against a pre-binary. Partial by construction and safe by construction: an empty slot (skipped file, or a genuinely empty one) falls through to the caller's own read, which returns the same bytes, so fast and slow paths cannot disagree; a size guard keeps a vector built for another corpus in bounds. Retention is a SINGLE point placed before the tree is built, so no exit can forget it and no branch can keep it twice; workers only ever write distinct pre-sized slots, verified under ASan+UBSan (-fno-sanitize-recover=all, LSan suppressions) clean on both corpora with output still identical. Cost measured honestly: peak RSS 182.5 -> 192.7 MB (+5.6%) for one corpus of text held across the lint block. churn=self on astQueryGrouped/builtInLintCaptures/runLint/lintSymbolLevelChecks/mergeNamingLens is lane B (one day earlier) plus this round own first commit. Frozen-corpus profile: mergeNamingLens 19.5 -> 6.3 ms (the naminglens getBytes row is GONE, 907 calls -> 0), lintSymbolLevelChecks 45.1 -> 37.7 ms, readFile 2335 -> 1168 calls; warm --lint 0.51-0.52s -> 0.42-0.43s. 20 gates green, determinism + xmllint clean

Every existing caller is byte-identical; the facet is the deliberate arity change the ack-only help names. | prior: A2 (dropped_positive, 2026-09-03): packSignatures gained one trailing droppedPositiveOut out-param and the post-ladder accounting inside the rank-adaptive branch — same shared-arithmetic reason as its JSON sibling.
 ack api-surface eed0ae8252dc773c 6 WAVE-2 close (2026-08-19), finding 3 of 3: the 76 remaining gating rows, ONE change. All of them are W2-E's root-relative p= landing (9beaa2c/fccea68/a271e6c/b3fe074 plus the f9108b7 correction), measured for the first time at WAVE granularity. The per-lane acks written during W2-E covered only the correction round's own diff (working-tree-vs-HEAD at that moment), so the original ~30-verb landing was never QD-acked; this ack closes that gap rather than re-accepting anything. Verified by reading the whole 20cdc04..860291c src/main.cpp diff line by line: 282 of 448 added lines match the root-relative predicate directly and every one of the remaining 127 is an existing std::printf rewritten from ing.files[...] to the root-relative rp local, plus four extracted emit helpers (computeDirModules, printJsonSymbolRows, writeOversizeRows, writeDropRows). No unrelated logic rides in. By kind: api-surface 28 = the +1 rootArg/rootPrefix parameter on the emitters that must now be TOLD their root (writeAbiCheck/Ref/Struct, emitColumnar*, packBodies/Deps/Lego/Outline/Signatures[Json], serialize[Json], writeLayout*, packConnect, buildD1Row and the report writers) - defaulted wherever a caller could stay unchanged. complexity 31 and verbosity 16 = the single-root-condition ternary and its guarded root= clause applied per emitter, with no new nesting level and no new control flow beyond that one conditional; the large absolute numbers (runStructureText 207->231, runLint 313->323, runMaintenanceViews 174->190, runCallHierarchy 71->80) are pre-existing dispatcher size the wave adds to, not creates - decomposing them is its own round and is recorded as a wave-2 follow-up. params 1 = writeNonLocalStateReport 4->6, the same contract. The three sibling lanes are individually clean: --quality-delta at f6ec56d..1732fd8 (W2-J), 1732fd8..9a41c74 (W2-K) and 9a41c74..20cdc04 (W2-F) each report gating=0. Full suite green at this head: gates=429 pass=427 skip=2 fail=0, ASan+LSan clean, byte-deterministic, xmllint clean. churn= is unavailable in ref-pair mode by construction (both trees materialized out of the repo), so short-horizon-churn is silent here and that silence is not evidence.
 ack api-surface efd276ea4e37021f 6 cid=8f6887043197d2a3 lane B1 cap disclosure: these five out-params ARE the disclosure. extractMentions, liftPackageDirMention, gitLogFileSets, gitRecentCommitFileSets and applyCoChangeBoost each gain ONE census output so a cap that cut invisible content can be told apart from a corpus that simply ran out, and none of the five facts is reconstructable downstream — the caller cannot see what the indexer refused to index. Every one is defaulted or updated at every call site in the same commit.

Subject: [PATCH 15/87] fix(skillsinstallcheck): make arm 5 actually exercise
 prune's link-safety
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Arm 5 previously deleted a real tracked skill's manifest line before
repointing its symlink outside the destination, which meant pruneStale
(correctly) never considered that name stale — it's only ever compared
against previous.skills, and the arm had just erased it from there. The
canary survived because nothing ran against it, not because unlink's
link-safety was exercised.

Mirror arm 4's construction instead: plant a symlink at a name that IS
recorded via a `skill=` line but is NOT a currently-embedded skill, then
run install. This makes pruneStale genuinely reach the entry, and now
the arm additionally asserts the stale link-unsafe entry itself was
removed, not just that unlink didn't follow it into $outside.

No src/ change — this is a gate-fixture fix only; src/skillsinstall.h's
pruneStale was already link-safe by construction (unlink never follows
a symlink at the final path component).

Subject: [PATCH 16/87] test(skills-install): add failing gate arms for
 per-agent modes, --all, --contributor

- arm 6: --codex and --hermes per-agent modes should install to agent-specific dirs
- arm 7: --all flag should detect and activate every present agent
- arm 8: --contributor flag should gate the contributor-only skill

These arms currently fail because the C++ code doesn't support these flags yet.
Task 8 will implement the flag parsing and logic to make them pass.

Subject: [PATCH 17/87] fix(skillsinstallcheck arms 6-8): correct sandbox
 pattern to match arms 1-5

The initial append used d="$( sandbox )" which recreates the subshell bug that
arms 1-5 already fixed. Per the file's own warning (lines 12-13), command
substitution forks a subshell where exports never reach the parent, causing
ripwire to run against the real $HOME instead of the sandbox.

Fix all three arms to follow the established pattern:
- Call sandbox bare (no subshell)
- Capture d from parent: d6="$d"
- Arms 6 and 7 need multiple sandboxes (one per agent mode tested)

Also strengthen arm 7's assertion to check both claude and codex directories,
ensuring the test isn't vacuous and genuinely tests --all detection.

Subject: [PATCH 18/87] feat(skills-install): per-agent modes, --all detection,
 --contributor gating
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- wrap.h: add resolveSkillsRoot() to resolve a kAgentTargets skillsRoot doc string
  (e.g. "${AGENTS_HOME:-~/.agents}/skills") into a real path, honouring the same
  env var each agent's own recipe names. Previously only ever printed as a comment.
- skillsinstall.h: refactor runSkillsInstall's body into installForAgent(agentName,
  contributor, force, executablePath), parse argv[3..] for agent flags (--claude/
  --codex/--codex-legacy/--openclaw/--hermes), --all, --contributor, --force, --hook.
  --all reuses wrap.h's getAgentConfigs() for presence detection, augmented with a
  resolved-skills-root-parent-exists check (Codex's config-dir detector is orthogonal
  to its skills root). --contributor gates via skillDirIsContributorOnly, an in-memory
  front-matter scan of the embedded SKILL.md bytes (ripwire-opt-remarks is the one
  contributor-only skill today). --codex-legacy is a destination override of the codex
  identity (${CODEX_HOME:-~/.codex}/skills), not a new kAgentTargets row, matching
  skills/install.sh's own model. --hook is parsed but mergeHookConfig currently reports
  "not implemented yet" and fails rather than silently succeeding (Task 12 supplies
  the real implementation).

test/skillsinstallcheck.sh arms 1-8 all pass. Full gate suite (pargates.py -j2):
633 gates, 617 pass, 4 skip, 12 fail — same totals as the pre-Task-8 baseline; the two
newly-failing gates (pargatescheck, runtracecheck) are unrelated timing assertions
under machine memory pressure, not caused by this change.

Subject: [PATCH 19/87] fix(skills-install): --all propagates per-agent/hook
 failures; correct hermes comment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- runSkillsInstall's --all loop tracked no failure state: an installForAgent error or
  a mergeHookConfig failure were both printed but discarded, and the loop always
  returned 0. "ripwire skills install --all --hook" therefore exited 0 while every
  agent's hook merge visibly failed — the same quiet-omission CLAUDE.md forbids,
  scoped to --all (the single-agent path already propagated this correctly). Now
  tracks anyFailure across the loop and returns 1 if any per-agent install or --hook
  merge failed.
- Corrected a misleading comment in installForAgent's skill-selection loop: it claimed
  skills/hermes/ content is linked under --hermes specifically. The actual filter
  (skillDir.rfind("ripwire-",0)!=0) is agent-independent — --hermes links the same
  ripwire-* set every other mode does today. Per-agent skill selection is later-task
  territory; the comment now says so instead of describing behavior that doesn't
  exist yet.

Verified live: `ripwire skills install --all --hook` now exits 1 (was 0).
test/skillsinstallcheck.sh: arms 1-8 still all pass.

Subject: [PATCH 21/87] feat(skills-install): --hook merge via jq, preserving
 pre-existing entries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces the Task 8 stub in mergeHookConfig with a real jq-based merge of
ripwire's PreToolUse (+ SessionStart, on first registration) hook into
~/.claude/settings.json, ported from skills/install.sh's install_claude_hook.
Existing registrations are recognised by hook-script basename (jqIsScript),
not exact path, so a prior copy's entry is refreshed in place rather than
duplicated. The merged JSON is computed by jq (captured via a local popen()
reader, not verbs_change.h's runCommandCapture — reusing it would require
nesting rw::skillsinstall inside main.cpp's verb-dispatch anonymous
namespace) and written back through rw::pathguard::openNoFollowTruncate/
writeAllAndClose, the same house pattern Task 6 used for the manifest
sidecar. codex (hookSlot=true but a different settings file/matcher/route
script this port does not cover) and hermes/openclaw (hookSlot=false) both
fail cleanly rather than writing to the wrong place.

Subject: [PATCH 22/87] fix(skills-install): correct runCommandCapture comment,
 dedup shell-quoting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review fixes for the --hook merge (no behavior change):

- The comment explaining why runCommandCapture (src/verbs_change.h) isn't
  reused cited the wrong mechanism (a namespace-nesting/redefinition claim
  that doesn't actually hold). The real, verifiable blocker is
  verbs_change.h:2-4's `#if !defined(RIPWIRE_MAIN_TU) #error` guard, combined
  with skillsinstall.h being #include'd at main.cpp:52 — 477 lines before
  RIPWIRE_MAIN_TU is #defined at main.cpp:529. Rewrote the comment to say so.
- Removed the local shellSingleQuote reimplementation and switched to the
  project's existing canonical rw::shSingleQuote (src/infra/jsonesc.h),
  which that file's own header comment says was consolidated there
  specifically to end duplicate copies of this same escaping logic.

Subject: [PATCH 23/87] test(wrap): update section 7 for the collapsed
 single-line skills-install probe
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

redhat-et/ripwire#225 task 11 (RED-first): section 7 now asserts the future
collapsed contract — one unconditional "<resolved binary path>" skills
install[ <agent flag>] line on every install layout — instead of the old
three-arm filesystem probe (checkout / curl-staged prefix / dead-end
comment). Adds mise-shim and aqua-proxy fixtures (per
prompts/help-wanted/install-discovery-mise-aqua.md's repro snippet) beside
the existing checkout, prefix and bare-binary cases; every case also
asserts the old bash skills/install.sh and 'skills not found locally'
forms are ABSENT. The regex is not $-anchored because the real line (task
12's plan, src/wrap.h) carries a trailing '# deploy to ...' comment.

src/wrap.h is untouched — section 7 fails against today's still-unmodified
wrapPrintSkillsLine, which is the point: task 12 makes it green.

Subject: [PATCH 24/87] feat(wrap): collapse the skills-install probe to one
 unconditional line

Skills are embedded in the binary itself (redhat-et/ripwire#225), so
wrapPrintSkillsLine's old three-arm filesystem probe (checkout cwd,
staged prefix copy, dead-end comment) has nothing left to probe for.
Replace it with one line, `"<resolved binary path>" skills install[
<agent flag>]`, plus a separate opt-in `--hook` line where the agent
has a hook slot. Guard the one real degrade path: selfExecutablePath
can return "" on failure, in which case print a comment instead of a
dead-quoted command.

test/wrapverbscheck.sh section 3 and its header item 4 asserted the
old `skills/install.sh` substring; update both to assert the new
collapsed-line shape (same regex section 7 already uses).

Subject: [PATCH 25/87] fix(skills-install): extracted hook scripts must be
 executable (0755)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

writeStoreFile hardcoded mode 0644 for every extracted file, which is
correct for skill markdown but wrong for hooks/*.sh — the repo tracks
those at 0755, and --hook's settings.json registration writes a bare
path as `command`, which the shell execs directly (verified: `sh -c
"<0644 path>"` fails, Permission denied, exit 126). Every hook script
extracted through this path was silently unrunnable.

Thread an explicit, required mode_t through extractGroup and
writeStoreFile so ensureStoreExtracted states intent per group:
kSkillFiles stays 0644, kHookFiles becomes 0755. Adds arm 10 to
test/skillsinstallcheck.sh, written first to confirm RED against the
unfixed code before the fix landed.

Caveat: extractGroup skips extraction when storeRoot already exists
(immutable-by-hash), and kStoreKey hashes content, not mode — so an
already-extracted hooks store predating this fix stays 0644 until its
directory is removed and re-extracted.

Reviewer follow-up on d902e46b: the "existing stores keep their old
modes" caveat was only written down in a task report that won't ship
with the binary. Add the one-line note at extractGroup's
existence-check itself so the next person hitting it doesn't have to
re-derive it from the CMake embed step.

Subject: [PATCH 27/87] test(doctor): add failing gate for shim recognition and
 skills staleness
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

test/doctorstalecheck.sh proves --doctor --agent=claude must not misreport a
mise/aqua shim on PATH as a broken/STALE binary, must disclose an ambiguous
managed install rather than guess, and must distinguish "not yet installed"
from "genuinely stale" skills. Red-first: it fails against today's
codexdoctor.h, which knows nothing of MISE_DATA_DIR or the v2 manifest's
source= field — Task 14 makes it pass.

Registers the new gate in test/regression.sh's loop, gateexitcheck.sh's
FAILFAST pin (fail() exits 1 directly, no accumulator, same shape as
skillsinstallcheck.sh), and pargates-shard-weights.json; docs/gatecount_build.py
rewrote the gate-count sites in docs/EVALS.md, README.md and the deck.

Subject: [PATCH 28/87] feat(doctor): recognise mise/aqua shims by location,
 report skills staleness

binaryCheck now recognises a version-manager shim by fixed data-dir LOCATION
only (never by executing `mise which`/`aqua which`, which would read
cwd-dependent config) and resolves the managed install from the manager's own
on-disk layout, comparing candidate and self byte-for-byte. More than one
version directory (or zero/ambiguous candidates) is reported as a disclosed
`managed_unverified` state, distinct from both ok=1 and STALE.

skillsCheck gained a `.ripwire-manifest-v2` reader (this doctor's own small
parser, independent of src/skillsinstall.h) and compares a v2 manifest's
`source=` against the embedded rw::embedded_skills::kStoreKey to report
`stale="1"`; a missing manifest now reports `not_installed="1"` (ok=1, not a
failure) instead of reading as a broken install. `skillsCheck` takes the
repair command as a parameter so codex's and Claude's hints stay literal,
real commands instead of a post-hoc string splice. claudeInspect's hints
updated from the retired `bash skills/install.sh --claude` wording to the
embedded `ripwire skills install --claude` verb (Task 12).

Acks the resulting skillsCheck arity contract-change as deliberate.

test/doctorstalecheck.sh's 3 arms now pass; codexdoctorcheck.sh and
claudeconfigdircheck.sh remain green.

Part of redhat-et/ripwire#225 (task 14/16).

 ack api-surface e6bdc5187566f3d7 8 cid=615b35e39fe420e4 capture-audit 2026-09-04 wave-1 close: deliberate contract changes, each --edit-check incompatible=0 in its lane report — L4 (lane-L4.md, Symbols whose contract changed): pageDisclosure/computePageDisclosure +collectionCapped (defaulted), packLego +graphCountFloorAttr (defaulted), packConnect/writePrRootOpen/writeTestGateReport/writeTestGateReportJson/memberUsesArm +const Graph& for the M15 gauge; L5: enumerateRefs +filterNameHits out-param (defaulted, three callers source-compatible); L3: emitGrepUnindexed/grepAuxJson +window (the H4 <unindexed> paging fix, caller updated)
 ack api-surface ebaa8de80f3b5caa 2 cid=fbf73430469857ac A3 (review of #219), the other half of the TestRunnerIndex ack above: runHintClauseIfRows takes the root-relative predicate as well as the row count, because the clause's ROOT-RELATIVE sentence must answer to the same fact that spells run= itself — a multi-root run declares no root= and correctly keeps an absolute command, so a clause claiming relativity there is a wrong answer, not a cosmetic one. The parameter is the fix and there is deliberately no default: a defaulted false would let a caller silently drop the sentence, which is the silent-wrong-answer shape this lane exists to remove. All ten call sites pass the predicate they already hold (packtask, flipimpact, handoff, partition, prcontext x2, verbs_change x2, situ, testmap). Visible only now because #214 landed the one-parameter form onto main first; once this lane merges, main carries the two-parameter form and the row cannot recur. Proven by runhintcheck 2c/2d (the root-spelling matrix, and multi-root does not claim a relativity it does not have) and prcontextcheck 49 rows, full suite gates=629 pass=627 skip=2 fail=0.
+ack api-surface ece7c3239a69072f 2 cid=a8d5bf4b3b6560d1 skillsCheck grew an installCmd parameter (Task 14, redhat-et/ripwire#225) so codex/claude repair hints stay literal, real commands instead of a post-hoc string splice
 ack api-surface ed05ee0357d016f1 4 --lint reads the corpus ONCE (audit lane B2, second half): astQueryGrouped gains an OPT-IN keptBytesOut, so the walk that already reads every file hands its bytes to the two symbol-level passes that ran after it instead of each re-opening the same ~900 files one at a time on the main thread. The +1 param on astQueryGrouped/namingLensChecks/appendNamingFindings is that deliberate contract and it is DEFAULTED — the --ensemble caller passes nothing and is byte-identical, verified against a pre-binary. Partial by construction and safe by construction: an empty slot (skipped file, or a genuinely empty one) falls through to the caller's own read, which returns the same bytes, so fast and slow paths cannot disagree; a size guard keeps a vector built for another corpus in bounds. Retention is a SINGLE point placed before the tree is built, so no exit can forget it and no branch can keep it twice; workers only ever write distinct pre-sized slots, verified under ASan+UBSan (-fno-sanitize-recover=all, LSan suppressions) clean on both corpora with output still identical.

Subject: [PATCH 29/87] fix(doctor): add a repair hint to the shim-managed
 byte-mismatch row
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

shimBinaryCheck's single-candidate branch reported ok="0" with no hint=
when a resolved managed install's bytes differ from self — the one failing
row in this file that gave no repair guidance. Every other failure path
(fallbackBinaryCheck, mcpCheck, hooksCheck, skillsCheck) carries one.

No gate exercises this branch; test/doctorstalecheck.sh's 3 arms are
unaffected and still pass.

Subject: [PATCH 30/87] refactor(skills-install): skills/install.sh becomes a
 thin wrapper over the binary

Delegates to `ripwire skills install` (src/skillsinstall.h) instead of implementing
symlinking/hook-merge/manifest logic in bash. Checkout build (build/, build-release/) is
searched before a bare PATH lookup, never the other way, so a mise/aqua shim whose resolved
version depends on the invoking cwd is never preferred over an unambiguous local build.
Refuses an explicit destination-path positional loudly: the binary has no equivalent yet and
would otherwise silently install into the caller's default agent home instead.

scripts/install.sh no longer stages $prefix/share/ripwire/{skills,hooks} (nothing reads that
path once skills/hooks are embedded in the binary) and replaces its per-agent bash
detect-and-activate loop with a single `ripwire skills install --all` call, gated by
RIPWIRE_NO_ACTIVATE exactly as before.

Known gaps this exposes rather than causes (src/skillsinstall.h has not yet ported): Codex
--hook merge (deliberate Task 10 stub), Hermes-native skill selection, and explicit-path
destinations. See task-15-report.md for the full gate-by-gate before/after.

-# destination. Hermes: skills/install.sh --hermes installs to ${HERMES_HOME:-~/.hermes}/skills (the same
-# Agent-Skills-standard SKILL.md files Hermes loads natively, plus the Hermes-native skills under
-# skills/hermes/; no `--hook` support there yet — Hermes exposes hooks: pre_tool_call in config.yaml
-# but hooks/ripwire-nudge.sh still switches on Claude tool names, so the port has not landed). An explicit path remains supported for CI and other clients:
-# skills/install.sh PATH.
-# Add --hook explicitly to install the advisory PreToolUse + SessionStart hook for the selected client:
-# skills/install.sh --hook (Claude) or skills/install.sh --codex --hook (Codex). --openclaw installs to
-# that same cross-agent root (openclaw's own "compatibility skill root"); it has no hook slot.
+# skills/install.sh — thin wrapper. As of redhat-et/ripwire#225, skills/hooks are embedded in the

-# ── the PreToolUse matcher, in one place. It is not cosmetic: a matcher decides which tool calls the
-#    hook is ever SHOWN. Read/Glob are here because the whole-file read is the largest token sink in an
-#    agent loop and the one default a skill description cannot intercept; mcp__ripwire__.* is here for
-#    the hook's other job, the substitution meter (docs/SUBSTITUTION_METER.md), whose numerator would
-#    otherwise miss every agent that prefers the MCP server to the CLI; Edit/Write/MultiEdit/
-#    NotebookEdit are the `native-edit` class the EDIT band needs (never nudged, never in the rate).
-#
-#    THE SHAPE IS LOAD-BEARING (2026-09-05, terminality round A, lane T). Claude Code reads a matcher
-#    made only of letters, digits, `_`, `-`, spaces, `,` and `|` as a LIST OF EXACT TOOL NAMES; only a
-#    matcher holding any other character is a (JavaScript, unanchored) regular expression. The
-#    2026-09-04 form `Read|Glob|Grep|Bash|mcp__ripwire__` therefore compared `mcp__ripwire__` as a
-#    whole tool name and matched NO MCP call, ever — 0 MCP rows in 51,002 on the frozen snapshot, and
-#    a live tee on the installed hook saw the Bash and Read calls around an mcp__ripwire__whereis and
-#    never the call itself. The `.*` puts the matcher on the regex path; the `^(...)$` keeps it a
-#    whole-name match there, so `Edit` cannot also fire for NotebookEdit through the unanchored test.
-#    test/hookcheck.sh section (14) evaluates this string exactly as Claude Code does.

-# terminality round: PreToolUse, SessionStart and UserPromptSubmit all ended up doubled.
-#
-# `jqIsScript` matches the hook by its SCRIPT NAME, so any copy's registration is recognised. The
-# command's first word is taken before the suffix test, because the SessionStart entry carries a
-# trailing ` --session-start` argument. When an entry is found, both its matcher AND its command are
-# brought to the current values: refreshing one and not the other is how the stale half survives.

Subject: [PATCH 31/87] fix(skills-install): refuse a bare positional
 destination instead of silently misdirecting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`ripwire skills install <DEST_PATH>` was reachable directly on the compiled
binary — argv parsing only recognized `--`-prefixed tokens, so any other
token was silently dropped and the install fell through to the caller's
default agent home. skills/install.sh's own wrapper-level refusal (Task 15)
never covers this: it's a bash-script-only guard, not enforced by the
binary itself.

Real DEST_PATH support would require answering what --hook and contributor
filtering mean for a path with no agent identity — semantics install.sh's
own comment already defers ("no explicit-path positional yet"). So this
adds a loud refusal instead, matching install.sh's wording, before
ensureStoreExtracted() touches disk.

Adds arm 11 to test/skillsinstallcheck.sh: asserts nonzero exit, that
stderr names the rejected path, and that neither the default agent home
nor the rejected path is created.

Subject: [PATCH 32/87] fix(skills-install): support explicit DEST_PATH, refuse
 ambiguous positionals
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`ripwire skills install <DEST_PATH>` — part of the documented CLI surface
([--claude|--codex|--codex-legacy|--hermes|--openclaw|--all|DEST_PATH]) —
silently dropped any non-"--"-prefixed positional and fell through to the
caller's default agent home instead. Reachable directly on the compiled
binary, bypassing skills/install.sh's own wrapper-level refusal (Task 15),
which covers only that one script.

Implements real DEST_PATH support rather than refusal-only: main's pre-#225
skills/install.sh already had concrete semantics for this (mode="path" ->
dst="$explicitPath", "only one destination path is allowed", "--hook needs
--claude or --codex, not an explicit skill path"), so this mirrors them
rather than inventing new ones. installForAgent() gains an optional
explicitDest override that bypasses agent-table resolution entirely;
runSkillsInstall()'s argv loop now refuses (exit 2) an empty positional, a
second positional, --hook combined with a path, and --all combined with a
path. skills/install.sh's now-superseded refusal loop is removed so the
wrapper stops making a false claim about what the binary supports.

Adds arms 11-13 to test/skillsinstallcheck.sh covering explicit-path
install, the ambiguous-input refusals, and non-leakage into the default
agent home.

Subject: [PATCH 33/87] fix(skills-install): write kStoreKey into the manifest,
 not the binary path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

writeManifestV2 was writing the resolved ripwire binary's own filesystem
path into `source=`, but codexdoctor.h's skillsCheck compares that field
against embedded_skills::kStoreKey (a <version>-<hash8> content-hash
string). A path can never equal a hash string, so `stale` was true on
every real install, forever — defeating the exact doctor staleness
check Tasks 13/14 built. No existing gate caught this because
doctorstalecheck.sh hand-constructs its manifest fixtures with the
already-correct source= value, bypassing writeManifestV2 entirely.

Write kStoreKey directly instead. Drops the now-dead executablePath
parameter from writeManifestV2 and installForAgent (only used it to build
the wrong value); runSkillsInstall keeps its own executablePath parameter,
now [[maybe_unused]], since main.cpp's call site is out of scope here.

Adds skillsinstallcheck.sh arm 14: a real `skills install` followed by a
real `--doctor --agent=claude` against the same sandboxed HOME, asserting
ok="1" and no stale="1" — the end-to-end path no prior gate exercised.
Confirmed RED against the pre-fix code, GREEN after.

Subject: [PATCH 34/87] test: sandbox CLAUDE_CONFIG_DIR against ambient leaks
 in install/hook/release gates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Several gates overrode HOME per-invocation but never CLAUDE_CONFIG_DIR, which Claude
Code resolves ahead of HOME. In any dev shell that already exports it (ordinary once
this repo's own hook/skills wiring is set up), a bare `skills install`/`--hook` call
inside these gates wrote straight past the gate's own sandbox into the real config
dir — reproduced live against ~/.claude-work/settings.json while investigating
test/meterdisclosurecheck.sh (out of scope here, left untouched, carries the same
unprotected pattern).

- test/hookcheck.sh, test/hermesinstallcheck.sh, test/skillinstallcheck.sh,
  test/releaseinstallcheck.sh: unset CLAUDE_CONFIG_DIR up front, matching each file's
  existing CODEX_HOME/AGENTS_HOME/HERMES_HOME hygiene.
- test/claudeconfigdircheck.sh: same unset (arm (G)'s own "unset" arm was leaking
  through unset-in-name-only), plus updates for #225's consolidation (scripts/
  install.sh and skills/install.sh now delegate to `ripwire skills install`, so
  arm (A)'s site-census floor drops 11->8 and arm (I)'s guard census follows the
  guard into src/skillsinstall.h via `skills install --all`'s own detection-skip).
- test/skillinstallcheck.sh: also fixes 4 explicit-DEST_PATH install.sh calls with no
  HOME= of their own -- `skills install <path>` extracts its embedded store cache
  under $HOME/.local/share/ripwire even when the destination is explicit, a second,
  narrower leak vector test/installer_isolation.py's sentinel check exists to catch.
- test/releaseinstallcheck.sh: also gives the release-install fixture's stub `ripwire`
  binary a real skills-install path (wraps the real local build) instead of a pure
  version-string echo, since `skills install --all` needs real behavior to answer;
  honors $RIPWIRE_BIN like every other gate.
- scripts/verify-agent-integration.sh: the non---live "sandbox" path built
  AGENTS_HOME/CODEX_HOME with an ambient-respecting default but never set
  CLAUDE_CONFIG_DIR at all; now forces all three into the sandbox in that branch and
  only respects ambient values in --live, where that's the documented intent.

Verified with: `CLAUDE_CONFIG_DIR=<throwaway> bash <gate>` and confirming the
throwaway stays empty, for all six files plus the three unrelated gates this task's
regression check covers.

From 52cc5c57d6aeb7eae9cc0856559864b9aa10347e Mon Sep 17 00:00:00 2001
From: Pedro Algarvio <pedro@algarvio.me>
Date: Fri, 18 Sep 2026 18:05:23 +0100
Subject: [PATCH 35/87] test: update wrap-truth gates for the collapsed
 skills-install command shape

Task 16 of redhat-et/ripwire#225: the last of four pre-existing gates that asserted
the old `bash skills/install.sh <flag>` command shape Tasks 11/12/15 replaced with
the collapsed `"<resolved-binary>" skills install <flag>` line, plus one shape drift
from Task 6's manifest schema bump.

- test/agenttablecheck.sh: arm (F)/(G) grep for `install.sh` (Task 12 dropped that
  literal from the recipe); also updates the installed-skills success-message grep to
  the new `skill(s) linked into` wording.
- test/codexdoctorcheck.sh: `.ripwire-manifest-v1` -> `.ripwire-manifest-v2` (Task 6's
  filename bump, never reflected here). The remaining failures in this file (doctor
  reports 11/12 checks passing, codex-skills row unhealthy) are NOT this: they trace
  to the doctor staleness bug fixed separately in a2f5... (commit 452473a9, arm 14 in
  test/skillsinstallcheck.sh) -- not re-verified here per that fix's own review.
- test/sourceinstallcheck.sh: the installed-prefix wrap recipe now names the staged
  binary's own resolved path, not skills/install.sh; also resolves $TMP to its
  canonical form (realpath) before comparing, since the recipe prints the binary's
  OWN syscall-resolved path and macOS's /var -> /private/var symlink makes mktemp's
  raw path and the binary's canonical path different strings for the same file.

Ran standalone after every edit, not just as part of a sweep: an early version of the
regex fix here (`^"[^"]+" skills install --codex$`) anchored past the recipe's
trailing same-line `# deploy to ...` comment and silently never matched.

Subject: [PATCH 36/87] test: pin dangling/foreign-symlink repair and
 manifest-outcome contracts (C1/C2)

Adds arms 15-17 to skillsinstallcheck.sh ahead of the fix: a dangling v1-style
symlink must be repaired by a bare install, a foreign-but-live symlink must
require --force to repair, and a link-loop failure must exit non-zero with a
manifest that records only what actually linked.

Subject: [PATCH 37/87] fix(skills-install): repair dangling/foreign symlinks,
 record link outcome (C1/C2/I7)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

C1: symlink_status() on a dangling symlink reports type()==symlink, not
not_found, so installForAgent's exists(destStatus) check read every v1-upgrade
checkout link as "already there" and skipped it forever; --force could not
repair it either, since it only ever relinked an entry already pointing at
this store. A dangling symlink is now repaired unconditionally (nothing real
is there to lose); a foreign-but-live symlink still requires --force, which
now actually relinks it instead of refusing on target mismatch. A real
file/directory at the destination is still refused either way.

C2: the manifest now records skills that actually linked (created, repaired,
or already-correct), not the full attempted set — a failed entry is no longer
declared present. Every link-loop failure (symlink_status error, unreadable
symlink, stale-link removal failure, linkOrRefuse failure, --force refusing
real content) is reported to stderr and counted; InstallOutcome gains
`failed`, and both the bare and --all paths now exit non-zero when any entry
failed instead of silently exiting 0 with an overclaiming manifest.

I7: pruneStale restores the `ripwire-*` name-scope guard alongside its
existing path-traversal check — a manifest line is user-writable text, and
this sweep's authority never extended past the names it itself would link.

Subject: [PATCH 38/87] fix(wrap): shell-escape the skills-install recipe path
 (C3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

wrapPrintSkillsLine double-quoted the resolved binary path unconditionally,
new exposure vs the old fixed-literal line: double quotes do not stop
$(...) or a backtick, so a path containing either executes when the recipe
is pasted. Switch to rw::shSingleQuote (already used elsewhere in this
file), which is inert to every shell metacharacter.

Updates every consumer of the printed shape from the old
'^"[^"]+" skills install' regex to '^'\''[^'\'']+'\'' skills install':
test/wrapverbscheck.sh, test/skillinstallcheck.sh, test/hermesinstallcheck.sh,
and scripts/verify-agent-integration.sh (which eval's the printed command
verbatim — still safe, since eval'ing a single-quoted literal cannot inject).
Also closes an "arm that cannot fail" in verify-agent-integration.sh: a
present-but-unmatched skills-install line used to fall through to the same
`note` branch as the legitimate "no skills root for this agent" case,
silently passing a print-site regression; it is now a `no`.

Subject: [PATCH 39/87] fix(doctor): shim-aware binary-path row, legend covers
 managed/stale skill attrs (I1/I5)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I1: the top-level --doctor `binary-path` check never got the shim-recognition
fix codexdoctor.h's `codex-binary`/`claude-binary` rows already have (Task
14) — a mise/aqua shim's mtime/size are the shim's own, not the managed
binary's, so the plain dev/ino-then-mtime/size comparison false-positived
STALE for every such user. Reuses rw::codexdoctor::isKnownShimPath +
shimBinaryCheck verbatim rather than re-deriving a second copy.

I5: doctorLegendComment() never defined managed=, managed_unverified=,
not_installed=, or the skills rows' own stale= (distinct from
tracked-binaries' stale=, already documented) — an agent reading only the
legend had no way to know what those attributes meant.

skills install --codex is implemented and works; use it here too. hooksCheck's

Subject: [PATCH 41/87] test: read the hook matcher from skillsinstall.h, not a

skills/install.sh is now a thin wrapper with no hookMatcher= line of its own,
so arm (D)'s sed always captured an empty string and could never pass. Reads
kClaudeHookMatcher out of src/skillsinstall.h instead, with a refusal if that
also comes up empty so this can't go vacuous again.

 stays deleted (I2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These two assertions still checked for skills/hooks staged under
$prefix/share/ripwire/{skills,hooks} — a contract scripts/install.sh
deliberately deleted (#225: skills/hooks are embedded in the binary now,
activated via `ripwire skills install --all`, already covered by arm E1).
Flipped to assert the directories are ABSENT, which is the current, correct
contract, rather than leaving two undisclosed reds pinning removed behavior.

Subject: [PATCH 43/87] docs: INSTALL.md names ripwire skills install, not the
 removed skills/install.sh path (I4)

scripts/install.sh no longer creates ~/.local/share/ripwire/skills/install.sh
(#225: skills/hooks are embedded in the binary). Every command in the skills
table, the advisory-hooks section, and the two prose mentions now names
`ripwire skills install [--agent] [--hook]` instead. deckcheck_allowlist.txt
gains --claude, matching the existing --codex/--hermes/--openclaw/--contributor
entries for the same table.

Subject: [PATCH 44/87] fix(skills-install): refuse an unknown --flag by name
 instead of treating it as an agent (M2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Any `--foo` not matched by the five known control flags fell through to
`agentArg = "foo"` silently and only failed downstream in installForAgent,
with a message that reads as "no such agent" rather than "no such flag" —
confusing for a typo like --forc (for --force). Validated up front against
kAgentTargets (plus codex-legacy, a destination override rather than a table
row) and refused immediately, rc 2, with the flag itself in the message.

Subject: [PATCH 45/87] fix(skills-install-wrapper): warn on the cwd-dependent
 PATH fallback (M6)

find_ripwire()'s own comment already explains why: a version-manager shim
resolves differently depending on the CURRENT DIRECTORY this script is
invoked from, and the checkout-build branch exists specifically to avoid
that ambiguity. The PATH fallback used it silently; now it says so, naming
the resolved path, so a wrong shim pick is visible instead of assumed.

Subject: [PATCH 46/87] test(routehookcheck): scope V4's Codex check to doctor
 rows, not the shared legend

I5's legend now names codex-skills unconditionally (it defines the attribute for
every --agent), which made V4's whole-document grep for 'codex' fire on every
claude report regardless of what the rows actually say.

 the actual repair
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A live foreign symlink blocking a declared skill name makes a plain re-run of
the parity hint's own command a permanent no-op — --force is what actually
relinks it (installForAgent only relinks a foreign target under --force).
Verified end to end: plant a foreign symlink, doctor's hint now names
--force, running it clears the row to ok="1".

Subject: [PATCH 48/87] test: centralize agent-home env-var sandboxing in one
 sourced helper

Two gates leaked past their own sandbox and wrote into the operator's real
Claude Code config during this session's full pargates run:
test/routehookcheck.sh (missed by d038282c's CLAUDE_CONFIG_DIR fix, which
touched four other gates but not this one) and
test/codexinstallhonestycheck.sh (whose header claimed 'fully hermetic'
without ever unsetting CLAUDE_CONFIG_DIR). Both incidents were the same
list omitted from one more file, not a wrong list.

test/lib/unset-agent-env-variables.sh is now the one place that list lives:
CODEX_HOME, AGENTS_HOME, HERMES_HOME, CLAUDE_CONFIG_DIR, OPENCLAW_STATE_DIR
(every env var src/skillsinstall.h and src/wrap.h resolve ahead of HOME for
some agent target). Every gate that varies HOME= per invocation for an
install/hook call now sources it instead of hand-copying the list:
hookcheck.sh, hermesinstallcheck.sh, skillinstallcheck.sh,
releaseinstallcheck.sh, codexinstallhonestycheck.sh, meterdisclosurecheck.sh,
routehookcheck.sh. Verified against a canary copy of the real settings.json:
all seven now leave it byte-unchanged under a deliberately ambient
CLAUDE_CONFIG_DIR.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

C3: hermesinstallcheck.sh sourced the shared unset helper AFTER exporting its
own HERMES_HOME, so the helper's blanket unset clobbered it under set -u.
Reorder: source first, then export.

C1: skillsinstallcheck.sh's sandbox() never sourced the helper, so an ambient
AGENTS_HOME/HERMES_HOME/CODEX_HOME leaked past its own HOME= override for
--codex/--hermes arms.

C2: agenttablecheck.sh's arm (F) bound HOME/AGENTS_HOME/CODEX_HOME per
invocation but never HERMES_HOME, even though $skillsflag can be --hermes.

I0: claudeconfigdircheck.sh hand-rolled its own 'unset CLAUDE_CONFIG_DIR'
instead of the shared helper, and its --all arm (which walks every detected
agent) bound none of AGENTS_HOME/CODEX_HOME/HERMES_HOME/RIPWIRE_DATA_HOME.
Now sources the shared helper once at the top, covering every arm.

M7: verify-agent-integration.sh's sandbox branch bound AGENTS_HOME/CODEX_HOME/
CLAUDE_CONFIG_DIR but not HERMES_HOME or RIPWIRE_DATA_HOME; $AGENT is a free
CLI arg, so 'verify-agent-integration.sh hermes' could write into the
operator's ambient $HERMES_HOME under a sandbox banner.

M1: unset-agent-env-variables.sh's header claimed OPENCLAW_STATE_DIR is
checked ahead of HOME for openclaw — no code reads that var; openclaw always
resolves a literal ~/.agents/skills. Corrected, and added RIPWIRE_DATA_HOME
to the unset list, and documented that sourcing order is now load-bearing.

Subject: [PATCH 50/87] fix(test): neutralise CLAUDE_CONFIG_DIR and
 RIPWIRE_DATA_HOME in installer_isolation.py (I4)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

dataHome() in src/skillsinstall.h reads RIPWIRE_DATA_HOME ahead of
$HOME/.local/share/ripwire, and extractGroup() early-returns when storeRoot
already exists — so a gate asserting store contents would silently read the
operator's real store if RIPWIRE_DATA_HOME were ambient. The Python isolation
gate's own var list did not cover this or CLAUDE_CONFIG_DIR. Verified: with
both added, the two pre-existing failures (ghost-prune, --hook unimplemented)
are unchanged from the 4-var baseline — this fix introduces no new failures.

Subject: [PATCH 51/87] fix(test): update stale quote/recipe-shape assertions
 and per-arm temp redirects (I5,I7,M8,M3/I6)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I5: sourceinstallcheck.sh expected the wrap recipe in double quotes, but C3's
wrapPrintSkillsLine now prints it through rw::shSingleQuote — single quotes.
Pattern updated to match, and its wording corrected: it resolves the binary's
own path now, not a staged Codex installer script (M8).

I7: codexwrapcheck.sh still grepped for the pre-#225 'bash skills/install.sh
--codex' recipe line, deleted from wrap.h. Updated to the current single-
quoted-binary-path shape.

M8: deckcheck_allowlist.txt's --codex/--codex-legacy/--hermes rows still
described 'skills/install.sh's ... destination mode' after the verb moved to
the native subcommand; reworded to match the already-correct --claude row.

M3/I6: skillsinstallcheck.sh arms 3, 12, 13, 17, 18 redirected stderr to a
bare relative 'skills_install.err' (relative to the pargates cwd, the repo
root) and only rm'd it on success — a failing arm left it behind, dirtying
the shared checkout for other gates' git-status +dirty stamp. Redirected to
each arm's own per-arm sandbox temp dir instead. Verified: a full run of
skillsinstallcheck.sh leaves no skills_install.err in the repo root.

Subject: [PATCH 52/87] fix(test): restore OPENCLAW_STATE_DIR unset, trim
 comment that broke claudeconfigdircheck's guard-window scan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Advisor review caught two issues in the C1/C2/C3/I0/M7 commit before they
shipped: (1) I had dropped OPENCLAW_STATE_DIR from the shared unset list
instead of just correcting the header's false claim about it — restored,
kept belt-and-braces since no code reads it today; (2) my M7 comment in
verify-agent-integration.sh pushed the else-branch's literal $H/.claude
assignment more than GUARD_WINDOW=8 lines past the nearest real
CLAUDE_CONFIG_DIR reference, tripping claudeconfigdircheck.sh arm (A)'s
census scan. Trimmed the comment; arm (A) is green again (10/10 sites).

Canary leak sweep (AGENTS_HOME/CODEX_HOME/HERMES_HOME/CLAUDE_CONFIG_DIR/
RIPWIRE_DATA_HOME all pointed at a canary dir) found arm (F)'s per-invocation
env prefix bound HOME/AGENTS_HOME/CODEX_HOME/HERMES_HOME but never touched
CLAUDE_CONFIG_DIR or RIPWIRE_DATA_HOME — an ambient RIPWIRE_DATA_HOME wrote a
full extracted skills store into the canary. Sourced the shared unset helper
once at the top instead (this file never reads either var itself). As a side
effect this also stopped ambient CLAUDE_CONFIG_DIR from perturbing arm (K),
the already-disclosed ambient-env artifact — arm (K) is green now, unforced.

Subject: [PATCH 54/87] fix(skills-install): count and report foreign-entry
 skips instead of silence (I1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

installForAgent had two !force 'continue' sites — a foreign-but-live symlink,
and non-symlink content at a skill name — that skipped silently: no message,
no counter. 'skills install' would print '15 skill(s) linked' (should be 16)
and exit 0 with nothing on stderr; --doctor read ok=1 too, since liveSkills
(codexdoctor.h) uses is_directory() which follows symlinks. A direct hit on
CLAUDE.md non-negotiable #3 (every truncation must be disclosed).

Added InstallOutcome.foreignSkipped, incremented at both sites, surfaced as
an append-only ', M skipped (run --force to relink foreign entries)' suffix
on both the bare-command and --all per-agent summary lines — the existing
prefix format string is byte-identical, so agenttablecheck.sh's grep for
'skill(s) linked into' and verify-agent-integration.sh's sed extraction of
the linked count are unaffected (both verified green after this change).

Extended skillsinstallcheck.sh arm 3 (which already plants a foreign live
symlink and runs a bare install) to assert the skipped count appears, rather
than adding a new arm for a fixture that already existed.

Subject: [PATCH 55/87] fix(codexdoctor): name what's actually blocking instead
 of a hint that can't fire or can't repair (I2,I2b)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I2: the manifest-parity hint's parenthetical named the foreign-symlink case,
but that row's ok never goes false for a foreign symlink (liveSkills follows
symlinks via is_directory(), same as I1 found for --doctor generally) — a
trigger the row cannot detect. And in the case that DOES fire (declared <
live, i.e. untracked non-symlink content), running the printed --force
command does not clear it — installForAgent correctly refuses to overwrite
real content, so the row stays red with the same hint forever. Now the
declared<live branch names the untracked entries directly instead of
prescribing --force; the declared>live branch (something manifest-tracked
went missing from disk, which --force can legitimately repair) keeps the
original hint.

I2b: the Codex hook-repair hint still told the operator to run
'skills/install.sh --codex --hook', which now routes into the Codex --hook
merge refusal ('not implemented yet', exit 2, no hooks.json written) — the
script that had the real install_codex_hook is gone; the hint would silently
no-op. States plainly that Codex hook registration isn't available in this
build. test/codexdoctorcheck.sh:105 updated to match; grepped
routehookcheck.sh too (advisor's suggestion) and it does not consume this
string, so only the one gate needed updating.

Subject: [PATCH 56/87] fix(test): mise/aqua arms discriminate the shim's own
 path; drop stale RED comments (I3,I3b)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I3: selfcontainedcheck.sh's skills-install arm was written before the
subcommand existed — both its success and failure branches printed ok,
vacuously. Now asserts success outright.

I3b: wrapverbscheck.sh's mise/aqua fixture arms had degraded to asserting
only a generic single-quoted-path shape, which matches ANY path — the arms
exist specifically to prove the recipe names the SHIM's own resolved target
($MISE_INSTALL/ripwire, $AQUA_INSTALL/ripwire), not just some path. Added
that exact-path assertion (against REAL_TMP, the pwd -P canonical form —
$TMP itself differs from it on macOS, same gotcha sourceinstallcheck.sh
already handles). assert_skills_line()'s own negative greps for the two
deleted strings ('bash skills/install.sh', 'skills not found locally')
were already correct positive-shape assertions, contrary to the review's
read of them — left as-is; only the two stale 'RED until rewritten' header
comments (wrapPrintSkillsLine was rewritten 40+ commits ago) were removed.

Subject: [PATCH 57/87] fix(test): doctorstalecheck.sh positive assertions +
 sentinel enforcement (I3d); plug two more RIPWIRE_DATA_HOME leaks found by
 canary sweep

I3d: doctorstalecheck.sh arm (a) only checked a negative (claude-binary row
is NOT ok=0) with no positive counterpart, so a renamed/dropped row would
pass having checked nothing. Its own header claims '--doctor must never
execute anything to figure that out' but nothing grepped the shim fixture's
sentinel string, so that claim was entirely unenforced. Added both: a
positive ok=1 assertion, and a grep that fails if the sentinel ever appears
in --doctor's output (proof the shim was never executed). Also added
trap ... EXIT on each mktemp -d tree (previously leaked on any fail(), which
exits immediately) and sourced the shared unset helper in sandbox() (it only
bound HOME/CLAUDE_CONFIG_DIR before).

Additional findings from the canary sweep (not named in the round-2 review,
found by running it against every gate touched this session): codexdoctorcheck.sh
and selfcontainedcheck.sh both invoke a path that reaches dataHome() without
ever touching RIPWIRE_DATA_HOME, so an ambient one would leak a full store
extraction into it. Neither is in the seven gates the review said already
source the shared helper. Sourced it in both, same one-line fix as I4.

Subject: [PATCH 58/87] fix(docs,install): correct INSTALL.md staging claim;
 gate the hooks hint on actual activation (I3c,M9)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I3c: INSTALL.md claimed ./install.sh (the source build) 'activates the skills
... skills and hooks are embedded in the ripwire binary itself, not staged
as separate files' — false for that route. CMakeLists still stages skills/
and hooks/ to share/ripwire/..., and install.sh still resolves and executes
that staged skills/install.sh (test/sourceinstallcheck.sh asserts the
staging exists). Corrected to describe what each installer actually does:
./install.sh stages and runs the staged script; scripts/install.sh (the
release installer) is the one with skills/hooks embedded, nothing staged.
Also aligned the RIPWIRE_NO_ACTIVATE=1 wording with scripts/install.sh's own
message ('skills not activated', not 'stages only' — there is nothing to
stage on that route).

M9: scripts/install.sh printed 'Optional advisory hooks: ...' unconditionally,
even after 'skills install --all' reported 0 agents configured (nothing to
hook into). Now captures the activation output, prints it as before, and
only shows the hooks hint when the parsed 'N agent(s) configured' count is
> 0; otherwise says plainly that nothing was activated. Verified against
test/releaseinstallcheck.sh (E1)-(E7), all still green; no gate greps the
old unconditional hint string.

+## Per-finding summary
+
+**C3** — `test/hermesinstallcheck.sh` sourced the shared unset helper *after* exporting its own
+`HERMES_HOME`; the helper's blanket unset clobbered it under `set -u`, aborting the gate with
+`HERMES_HOME: unbound variable`. Reordered: source first, export after. Also added a load-bearing
+ordering note to `test/lib/unset-agent-env-variables.sh`'s own header, as asked.
+
+**C1** — `test/skillsinstallcheck.sh`'s `sandbox()` never sourced the shared helper, so an ambient
+`AGENTS_HOME`/`HERMES_HOME`/`CODEX_HOME` would leak past its own `HOME=` for the `--codex`/`--hermes`
+arms. Fixed by sourcing the helper inside `sandbox()`.
+
+**C2** — `test/agenttablecheck.sh` arm (F) bound `HOME`/`AGENTS_HOME`/`CODEX_HOME` per invocation but
+never `HERMES_HOME`, even though `$skillsflag` can be `--hermes`. Added `HERMES_HOME` to that
+invocation's env prefix. Canary sweep (below) then found a **second, unnamed leak** in the same
+file — `RIPWIRE_DATA_HOME`/`CLAUDE_CONFIG_DIR` were never bound at all — fixed by sourcing the
+shared helper once at the top of the file instead of patching the per-invocation prefix again.
+
+**I0** — `test/claudeconfigdircheck.sh` hand-rolled its own `unset CLAUDE_CONFIG_DIR` instead of the
+shared helper, and its `--all` arm (which walks every detected agent) bound none of
+`AGENTS_HOME`/`CODEX_HOME`/`HERMES_HOME`/`RIPWIRE_DATA_HOME`. Replaced the hand-rolled unset with a
+single `source` of the shared helper at the top, covering every arm in the file (not just `--all`).
+
+**M7** — `scripts/verify-agent-integration.sh`'s sandbox branch bound `AGENTS_HOME`/`CODEX_HOME`/
+`CLAUDE_CONFIG_DIR` but not `HERMES_HOME` or `RIPWIRE_DATA_HOME`; `$AGENT` is a free CLI argument, so
+`verify-agent-integration.sh hermes` could write into the operator's ambient `$HERMES_HOME` under a
+"sandbox" banner. Added both vars to both branches (LIVE and sandbox) and to both places they're
+consumed (the install invocation and the `RESOLVED` path-expansion `sh -c`).
+
+Side incident on this same commit: the first version of the M7 comment I wrote pushed the
+`else`-branch's literal `$H/.claude` assignment more than `GUARD_WINDOW=8` lines past the nearest
+real `CLAUDE_CONFIG_DIR` reference in the file, tripping `claudeconfigdircheck.sh` arm (A)'s census
+scan (a genuine regression I introduced and caught before committing — see commit `174dbb8e`).
+Trimmed the comment; arm (A) is green (10/10 sites) after the fix.
+
+**M1** — `test/lib/unset-agent-env-variables.sh`'s header claimed `OPENCLAW_STATE_DIR` is "checked
+ahead of HOME" for openclaw. Verified by grep: no code reads that variable anywhere in `src/`;
+`src/wrap.h` resolves openclaw through a literal `~/.agents/skills` path. Corrected the header to say
+so, and kept `OPENCLAW_STATE_DIR` in the unset list as belt-and-braces (I initially dropped it
+entirely in a first pass — the advisor caught that this was an unrequested isolation weakening, not
+what the task asked for; restored it).
+
+**I4** — `src/skillsinstall.h`'s `dataHome()` reads `RIPWIRE_DATA_HOME` ahead of
+`$HOME/.local/share/ripwire`, and it wasn't in the shared helper's unset list — added.
+`test/installer_isolation.py`'s own separate var tuple (`HOME`, `CODEX_HOME`, `AGENTS_HOME`,
+`HERMES_HOME`) didn't cover `CLAUDE_CONFIG_DIR` or `RIPWIRE_DATA_HOME` either — extended it. Verified
+the two pre-existing failures this gate already surfaces (ghost-symlink prune, Codex `--hook`
+unimplemented — both on the disclosed list) are unchanged before/after the fix, so it introduces no
+new failures.
+
+**I5 / M8 (sourceinstallcheck.sh)** — the case pattern expected the wrap recipe in *double* quotes;
+C3's earlier fix (`rw::shSingleQuote`) made the real output single-quoted, so the pattern could never
+match. Updated to single quotes and reworded the pass/fail messages ("resolves the binary's own
+resolved path", not "the staged Codex installer" — it doesn't resolve a staged file anymore).
+
+**I7 (codexwrapcheck.sh)** — still grepped for the deleted `^bash skills/install\.sh --codex` line.
+Updated to the current `^'[^']+' skills install --codex(...)` shape. (Needed a second pass: my first
+regex used a `$`-anchor that missed the real line's trailing `# deploy to ...` comment — fixed to
+match on whitespace-or-end instead.)
+
+**M3 / I6 (skillsinstallcheck.sh)** — arms 3, 12, 13, 17, 18 redirected stderr to a bare relative
+`skills_install.err` (relative to the `pargates` cwd, the repo root); each arm `rm`'d it on success
+but `fail()` exits immediately, so a failing arm left it in the shared checkout. Redirected each site
+to its own arm's per-arm sandbox dir (`$d3/skills_install.err`, `$d12/skills_install.err`, etc.).
+Verified a full run leaves no `skills_install.err` at repo root.
+
+**M8 (deckcheck_allowlist.txt)** — the `--codex`/`--codex-legacy`/`--hermes` rows still said
+`skills/install.sh's ... destination mode`; reworded to match the `--claude` row's already-correct
+`` `ripwire skills install`'s ... `` wording.
+
+**I1** — `src/skillsinstall.h`'s `installForAgent` had two `!force` `continue` sites (a foreign-but-
+live symlink; non-symlink content at a skill name) that reported nothing — no message, no counter.
+Added `InstallOutcome::foreignSkipped`, incremented at both sites, surfaced as an append-only
+`, M skipped (run --force to relink foreign entries)` suffix on both the bare-command and `--all`
+per-agent summary lines. Kept the existing prefix format string byte-identical so the two known
+consumers — `agenttablecheck.sh`'s `grep -q 'skill(s) linked into'` and
+`verify-agent-integration.sh`'s `sed` extraction of the linked count — are unaffected (both verified
+green). Extended `skillsinstallcheck.sh` arm 3 (which already plants exactly this fixture — a foreign
+live symlink, then a bare install) to assert the skipped-count message, rather than adding a new arm
+19 for a scenario the suite already had a fixture for.
+
+**I2 / I2b** — see "Ambiguous / not fully resolved" below for I2's premise; the fix itself is
+verified working (see empirical check). The manifest-parity hint's `declared < live` branch now
+names the untracked entry directly (`"ripwire-orient exists at this skill home but ... never linked
+it — remove it manually..."`) instead of prescribing `--force`; the `declared > live` branch (a
+manifest-tracked entry that's actually missing from disk, which `--force` genuinely can relink) keeps
+the original hint. I2b: the Codex hook-repair hint printed `run bash skills/install.sh --codex --hook`,
+which now routes into the Codex `--hook` merge refusal (exit 2, no-op) — changed to state plainly
+that Codex hook registration isn't available in this build. Updated `test/codexdoctorcheck.sh:105` to
+match; grepped `test/routehookcheck.sh` too per the advisor's suggestion — it does not consume either
+hint string, so no second gate needed updating.
+
+**I3** — `test/selfcontainedcheck.sh`'s `skills install` arm predated the subcommand's existence and
+had a branch where both success and "acceptable failure" printed `ok`. Now asserts success outright.
+
+**I3b** — `test/wrapverbscheck.sh`'s `assert_skills_line()` greps for two strings deleted from
+`src/wrap.h` 40+ commits ago (`bash skills/install.sh`, `skills not found locally`); those greps are
+correctly-still-negative (they should never match, and don't) — on inspection they were not vacuous
+the way the review described, they're legitimate "this old thing is gone" checks running alongside a
+real positive-shape assertion the function already had. What *was* genuinely degraded: the mise/aqua
+fixture arms only asserted a generic `^'[^']+' skills install...` shape, which matches *any*
+single-quoted path, when their whole purpose is to prove the recipe names the shim's own resolved
+target. Added an exact-string assertion for both (`$MISE_INSTALL/ripwire`, `$AQUA_INSTALL/ripwire`),
+built against `REAL_TMP` (`pwd -P`) rather than `$TMP` directly — `$TMP` and its canonical form differ
+as strings on macOS (`/var/folders/...` vs `/private/var/folders/...`), the same gotcha
+`sourceinstallcheck.sh` already works around. Removed the two stale "RED until wrapPrintSkillsLine is
+rewritten" header comments.
+
+**I3d (doctorstalecheck.sh)** — arm (a) had only a negative assertion (`claude-binary` row is not
+`ok="0"`) with no positive counterpart; added `ok="1"` as the paired positive. The gate's own header
+claims "must never execute anything to figure that out" but nothing grepped the shim fixture's
+sentinel string (`"this is a shim, not the real binary — must never be executed by --doctor"`); added
+that grep, failing if the sentinel ever appears. Also added `trap 'rm -rf "$d"' EXIT` inside
+`sandbox()` (previously each arm's temp dir only got cleaned by its own trailing `rm -rf`, which
+`fail()`'s immediate `exit 1` would skip), and sourced the shared unset helper in `sandbox()` (it
+only bound `HOME`/`CLAUDE_CONFIG_DIR` before).
+
+**I3c** — `INSTALL.md` claimed `./install.sh` (the source build) "activates the skills ... skills and
+hooks are embedded in the ripwire binary itself, not staged as separate files." Verified false:
+`CMakeLists.txt` still stages `skills/` and `hooks/` under `<prefix>/share/ripwire/`, and `install.sh`
+still resolves and runs that staged `skills/install.sh` (`test/sourceinstallcheck.sh` asserts the
+staging exists). Rewrote the paragraph to describe each installer accurately: `./install.sh` stages
+and runs the staged script; `scripts/install.sh` (the prebuilt/release installer) is the one with
+skills and hooks embedded, nothing staged. Also aligned the `RIPWIRE_NO_ACTIVATE=1` wording with
+`scripts/install.sh`'s own message ("skills not activated" — there's nothing to stage on that route).
+
+**M9** — `scripts/install.sh` printed `Optional advisory hooks: ...` unconditionally, even after
+`skills install --all` reported `0 agent(s) configured`. Now captures that command's output, still
+prints it verbatim, and only shows the hooks hint when the parsed `N agent(s) configured` count is
+`> 0`; otherwise prints "Nothing was activated — no detected agent to hook into." Verified against
+`test/releaseinstallcheck.sh` arms (E1)-(E7), all green; grepped for any gate consuming the old
+unconditional string — none found.
+
+## Additional findings, beyond the review's named list
+
+The canary leak-sweep (below) found two more `RIPWIRE_DATA_HOME` leaks the review did not name, in
+gates that were not among the seven the review said already source the shared helper:
+
+- `test/codexdoctorcheck.sh` — binds `HOME`/`CODEX_HOME`/`AGENTS_HOME` per invocation but never
+  touched `RIPWIRE_DATA_HOME`; an ambient one leaked a full store extraction into the canary.
+- `test/selfcontainedcheck.sh` — its `skills install` arm (the one rewritten for I3) hits the same
+  `dataHome()` path with no override.
+
+Both fixed the same way as I4/C2: source the shared helper once near the top of the file. Verified
+clean by re-running the canary sweep after the fix (see below).
+
+## Empirical leak-verification (canary sweep)
+
+Method: pre-create five canary directories (`claude/`, `codex/`, `agents/`, `hermes/`, `data/`) under
+one `mktemp -d`, point `CLAUDE_CONFIG_DIR`/`CODEX_HOME`/`AGENTS_HOME`/`HERMES_HOME`/`RIPWIRE_DATA_HOME`
+at them (pre-created, per the advisor's correction — an unpopulated canary that doesn't exist yet
+would make `--all`'s agent-detection skip it and falsely read as "clean"), run the gate, then
+`find <canary-root> -mindepth 1`. **Caveat**: the five pre-created empty directories themselves always
+appear in that `find` output — "clean" means nothing was written *inside* them, not that the listing
+is empty.
+
+Ran against every gate touched this session:
+
+| Gate | Result |
+| --- | --- |
+| `hermesinstallcheck.sh` | clean (5 empty shells only) |
+| `skillsinstallcheck.sh` | clean |
+| `agenttablecheck.sh` | clean *after* the `RIPWIRE_DATA_HOME`/`CLAUDE_CONFIG_DIR` fix (dirty before — this is how that second leak was found) |
+| `claudeconfigdircheck.sh` | clean |
+| `routehookcheck.sh` | clean |
+| `doctorstalecheck.sh` | clean |
+| `codexdoctorcheck.sh` | clean *after* fix (dirty before — full store extraction into the canary `data/` dir) |
+| `selfcontainedcheck.sh` | clean *after* fix (dirty before, same shape) |
+| `wrapverbscheck.sh` | clean |
+
+`installer_isolation.py` (I4) uses its own sentinel-snapshot method (not the canary-dir sweep, since
+it already does an equivalent-but-stricter check via byte/permission snapshots of seeded homes);
+verified separately by confirming the two pre-existing failures it surfaces are unchanged before and
+after the fix (see I4 above).
+
+`verify-agent-integration.sh` (M7) was verified by direct invocation (`bash
+scripts/verify-agent-integration.sh codex`) rather than the canary sweep — it's an interactive/manual
+tool, not a `test/*check.sh` gate `pargates` runs — confirming no `set -u` unbound-variable error and
+correct output.
+
+## Gate suite result
+
+`python3 test/pargates.py . ./build/ripwire -j 6` — run against a `--clean-first` rebuild of the
+final commit. See the appended summary below once the background run completes (the run exceeded the
+120s foreground timeout in this session and was moved to background monitoring).
+
+Reds observed this session, individually confirmed pre-existing (bisected against the commit
+immediately before this fix wave, `4acc5f3d`, running the SAME binary — not attributed by
+resemblance):
+
+- `skillinstallcheck.sh` / `releaseinstallcheck.sh`: "install.sh did NOT prune a dangling
+  ripwire-ghost symlink" and "--codex --hook did not create ~/.codex/hooks.json" — both on the
+  disclosed list (the deliberately-red ghost-prune assertion; Codex `--hook` merge unimplemented).
+- `routehookcheck.sh`: 5 failures, all naming `UserPromptSubmit`/router registration
+  (`I2 install: no UserPromptSubmit entry...`, `I3 install: 0 router entries...`, `I3b`, `I6`, `V2
+  doctor: route_hook is not 1`) — all on the disclosed list ("UserPromptSubmit routing hook not
+  wired"). Confirmed pre-existing by running the exact `4acc5f3d` copy of this file (in `test/`, via
+  `bash`, not a bare invocation — see caveat below) against the current binary: identical 5 failures.
+- `agenttablecheck.sh` arm (K) — was failing before this session's work (disclosed: "ambient-env
+  artifact"); after the `RIPWIRE_DATA_HOME`/`CLAUDE_CONFIG_DIR` fix to this same file (for the C2
+  leak, not for arm K), it now passes as a side effect of no longer leaking ambient env into the
+  gate's own detection logic. **I did not touch arm (K)'s assertion or logic** — flagging this
+  explicitly so a reviewer doesn't read the flip as an unauthorized fix to a disclosed, do-not-touch
+  item.
+- **hermesinstallcheck.sh — 5 failures, all newly *visible* because of the C3 fix, not newly
+  introduced.** At `4acc5f3d` (before C3), the gate died after ~3 arms with 2
+  `HERMES_HOME: unbound variable` errors and never reached the arms below that point. After the
+  reorder, the gate runs to completion and 5 arms fail:
+  `--hermes exposed 16 of 17 skills`, `--hermes manifest set differs (15 vs 17)`, `a default (Claude)
+  install overwrote/pruned the Hermes skill home (found=16)`, `the Hermes-native loop did not link
+  the planted ripwire-decoy-map`, `the --hermes manifest omits ripwire-decoy-map`. I traced all five
+  to one cause: `shipped=17` counts `skills/hermes/ripwire-repo-map` (a real Hermes-native skill in
+  the repo) plus the 16 flat skills, but the Hermes-native linking loop never actually links it — the
+  disclosed gap "Hermes-native selection unported." The first three failures are the same
+  16-vs-17 undercount surfacing three times (fresh install, post-Claude-install re-check, and the
+  manifest-set diff); the last two are a separate arm (7) that plants a *synthetic* Hermes-native
+  fixture (`ripwire-decoy-map`, its own SKILL.md, its own throwaway home) and asserts it gets linked.
+  Both arms 1 and 7 go through the identical code path — `skills/install.sh` is now a thin wrapper
+  (`exec "$ripwire_bin" skills install "$@"`, confirmed by reading it), so there is no separate
+  "shell installer" logic left to blame here, only `ripwire skills install --hermes` itself. One real
+  repo skill and one purpose-built fixture skill, reached through the same wrapper into the same
+  binary subcommand, both fail to link — that is the signature of the native-selection loop not
+  running at all, not a fluke or a fixture bug, which is why I'm treating all 5 as one disclosed root
+  cause rather than 5 separate opens. **This gate is now more red than it was before this fix wave,
+  and that is expected and correct**: the previous 2-error state was masking these 5 with a crash,
+  not fixing them. C3's job was to stop the crash, not to fix Hermes-native selection (out of scope,
+  disclosed, not attempted).
+
+*(Caveat on the routehookcheck baseline comparison above: my first attempt at this comparison copied
+the file to `/tmp` and ran it without `bash`, which silently failed with "permission denied" — a
+non-executable file invoked directly — and I misread the resulting empty grep as "0 failures,
+therefore pre-existing." I caught this from the exit code before drawing any conclusion from it, and
+redid it correctly: copied into `test/` so `$0`-relative `ROOT` resolution stays correct, invoked
+explicitly via `bash` to bypass the missing +x bit. The corrected comparison is what's reported
+above.)*
+
+## Ambiguous / not fully resolved — reported honestly
+
+**I2(a)'s stated premise does not reproduce in either scenario I tested.** The review states the
+manifest-parity row's `ok` "never goes false for a foreign symlink (it reads ok=\"1\" — blind)". I
+worked through the logic before writing the fix and concluded the opposite: `manifest.declared`
+(built from `linkedNames`, which excludes a skipped foreign entry) and `live` (built by
+`liveSkills()`'s `is_directory()`, which follows the symlink and counts it) should differ in both
+size and membership whenever a foreign symlink is skipped — which should make `parity` false and
+`ok` false, not blind. I ran the advisor's suggested empirical check twice (plant a foreign symlink
+into a live directory under a sandboxed `HOME`, run bare `skills install`, then
+`--doctor --agent=claude`) — once against a fresh skill home, once against a home with a prior
+successful install before the symlink swap — and both times got:
+
+```
+<c n="claude-skills" ok="0" manifest="1" declared="15" live="16" hint="ripwire-orient exists at this
+skill home but ripwire skills install --claude never linked it — remove it manually if it is not
+meant to be there"/>
+```
+
+`ok="0"` both times, not blind. I have not found or reproduced a scenario matching the review's
+literal "ok=1 for a foreign symlink" claim. My fix (the `declared < live` branch naming the untracked
+entry) is verified correct and produces the intended, more-honest hint in both scenarios I tried — so
+the deliverable is empirically sound regardless of which premise is right. But I'm flagging the
+discrepancy rather than silently assuming either the review or my derivation is wrong: it's possible
+the review's repro used a different construction (e.g. a *dangling* foreign symlink prior to some
+other code path, or a manifest v1 upgrade path I didn't try) that does hit a blind case I haven't
+found. If that's true, my fix's `declared < live` condition would simply never fire for that specific
+sub-case (falling through to the unchanged `declared > live` branch's `--force` hint) rather than
+being wrong — but I can't confirm that without knowing the exact repro the review used.
+
+**`test/releaseinstallcheck.sh:129` and its arm (E5) PASS line repeat the same false claim I3c fixed
+in INSTALL.md**: the comment says "RIPWIRE_NO_ACTIVATE=1 stages without activating" for
+`scripts/install.sh` (the release installer), which stages nothing — I verified this directly while
+fixing I3c. This is a test comment/message, not user-facing documentation, and wasn't named in the
+review's fix list, so I left it as found-but-not-fixed rather than expanding scope. Flagging with the
+exact location: `test/releaseinstallcheck.sh:129` (comment) and the `(E5)` `ok` message at line ~213.
+
+**ASan/UBSan tree** — not run, per the task's own instruction that it's optional/time-permitting and
+not required to complete this wave. Not attempted.
+
+## Skipped, per explicit instruction
+
+M2, M4, M5, M6, the `pargatescheck.sh`/`strkerncheck.sh`/`taskroutecheck.sh` timing items, and
+everything on the prior fix-wave's already-disclosed list — untouched, as instructed.

ACTIVATE_OUT="$( ... )"; ACTIVATE_RC=$? is a bare assignment under set -eu:
its exit status IS the substitution's, so a failing activation aborted the
whole install with nothing printed — the exact silent-failure class this
branch exists to close, and a regression from f56651c5's own M9 refactor
(the prior code was if-guarded and never hit set -e). ACTIVATE_RC=0 plus
|| ACTIVATE_RC=$? keeps this in the exempt-from-errexit OR-list shape while
still capturing the real code. Verified: a stub ripwire exiting 1 now
degrades with the existing hint printed, install continues, rc captured.

Subject: [PATCH 61/87] test: point four gate reads at .ripwire-manifest-v2,
 not the deleted v1 name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The binary has written .ripwire-manifest-v2 since the v2 manifest task landed
earlier on this branch; these four sites (hermesinstallcheck.sh:61,185,188,
skillinstallcheck.sh:49) never got updated. Two read against a v1 path that
never exists, producing false reds (a wc -l of empty output read as '1
entries', masking the real 17-vs-16 Hermes-native gap behind a wrong number);
two read a grep against a missing file that always vacuously passes,
regardless of what the manifest actually contains. Same defect class as the
sourceinstallcheck.sh/codexwrapcheck.sh quote/recipe misses fixed earlier in
this fix wave — an assertion left pinned to a name the branch renamed.
Verified: both gates now report real, disclosed-gap-consistent numbers, and
the two previously-vacuous arms now assert against real manifest content.

Subject: [PATCH 62/87] fix(codexdoctor): non-throwing directory iteration in
 shim layout resolution
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

resolveMiseLayout/resolveAquaLayout used a range-for over directory_iterator,
whose operator++ throws on a permission change or race mid-scan — exactly
the shape hazardpatterncheck's rule C exists to catch, now enforced on this
branch's own new code. Switched to the increment(ec) idiom liveSkills
already uses elsewhere in this file, and factored the now-identical
'list one level of subdirectories, non-throwing' body the two functions
shared into one listSubdirectories helper rather than duplicating the fix.

Subject: [PATCH 63/87] fix(skillsinstall): route raw POSIX calls through
 rw::os, register the two S2 sites
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Upstream's os-header lane made every POSIX/libc call and header route through
src/infra/os.h mandatory (osswitchcheck.sh rules B/F) after this branch had
already been written against raw ::open/::write/::rename/::symlink/::lstat/
::unlink/::popen/::pclose/::getpid, struct stat, mode_t and ssize_t — 18
violations, all in this one file, none of them noticed until the rebase onto
current main surfaced the rule. Added os::symlink (the one wrapper os.h
didn't already have; every other call site's wrapper already existed) and
switched every site to it; dropped the now-redundant raw <fcntl.h>/
<sys/stat.h>/<sys/wait.h>/<unistd.h> includes (os.h already provides them
transitively, same as pathguard.h's existing convention).

crashsweepcheck's S2 still flags an os::-spelled popen/open site if it isn't
registered — 'the seam's own spelling is not a free pass' — so registered
runShellCapture's popen (no exit between popen and pclose) and
writeStoreFile's open (the only early exit is the failed open; FdGuard
closes it on every remaining path) in test/crashsweepcheck.sh's registry,
matching every neighbouring entry's shape.

.ripwire_quality_acks covers the resulting quality-delta footprint (11
findings, all this same refactor's own churn/duplication noise) with one
consolidated reason.

 ack duplication a405a9c684c97953 781 timsort vendoring: every row is the vendored src/infra/timsort.hpp (upstream v3.0.1 + the recorded workspace patch) plus the facade forwarder it needs. The complexity/verbosity/params/duplication rows are UPSTREAM's shape — mergeLo/mergeHi, gallopLeft/gallopRight and the timsort/timmerge overload pairs are twins in the release itself — and restructuring them would destroy the property that makes the file auditable: that it can be re-derived byte-for-byte from a public tag plus one described patch. The one preexisting-worse row, infra::sort::stable vs infra::sort::unstable at 22 tokens, is what a facade IS: each entry is a one-line forward to a DIFFERENT algorithm, and collapsing them into one algorithm-parameterised template would hide the explicit named choice the layer exists to make (G5). Nothing is routed to timsort; test/timsortcheck.sh is what keeps the file honest.

WAVE-3 VERIFIER CORRECTION (P6-6): this reason previously named writeHealthRows as a third member, which is in NO clone group at all - that made the ack unverifiable against the ledger and made '2-instance' read as a three-way judgement it never was; and it cited 'the DOD doctrine' (G2), a DATA-LAYOUT guardrail that says nothing about a six-line emitter running once per report. The engineering call is unchanged and was independently attacked and NOT refuted. Its real authority is --quality-delta's own 'a wrong abstraction beats a low score' plus this repo's own fold threshold: src/mergescout.h:637 writeSymRows and src/main.cpp:8746 writeDropRows were folded because the attribute SCHEMA is identical and only the tag varies, while writeOversizeRows/writeDropRows sit deliberately UNFOLDED in the same block at a LARGER similarity=0.90 tokens=139, for exactly the discriminator that applies here - differing attribute sets. writeLangRows/writeUnindexedExtRows differ in the key attribute name (x= vs n=), the key SOURCE (a stored field ue.ext vs a derived rw::langTag) and the attribute arity (files= vs files=+symbols=), so they fall on the repo's own keep-separate side; every consolidation sketch is net longer, needs two callables per site, and drags the fixed-buffer snprintf into a lambda past test/fixedbufsweep.sh:259's per-site census (which this wave already had to re-pin 191->193). TREND, recorded rather than left silent: this six-emitter block now carries TWO unfolded clone pairs (139 preexisting + 89 new) and accretes sibling emitters by design. At a THIRD same-schema sibling, writeSymRows' three-caller precedent flips the answer - and it cannot creep there silently, because this ack is keyed at exactly tokens=89 over exactly these two members, so a third member is a new member set, a new group, and a new finding

All five gating rows are this lane's own footprint. TWO short-horizon-churn churn=self rows: kLangTable is the language table this change exists to extend, and kParserVer is the cache key an extraction change is REQUIRED to move (ingest_cache.h's own note says so) — both are structural for any lane of this kind, not thrash. THREE clone rows on isMarkdownGrammarExtension, all 35-token idiom collisions on a one-line membership predicate: it now spells the sorted-table + std::binary_search + is_sorted static_assert shape that externalnames.h::isShellBuiltinName/isPythonBuiltin/isCFamilyStdName already carry (their own note at externalnames.h:98 records this exact collision and settles on this shape), and the KindCounts::total pair is a std::accumulate over std::begin/std::end normalizing to the same token stream. Two cheaper spellings were tried and REJECTED by measurement first: a hand-rolled scan loop is the five-instance clone shape ingest.h::isNonTextExtension's note already names, and a std::find one-liner cloned KindCounts::total alone. What was FIXED rather than acked in this pass: six duplication rows (the loop -> the house binary_search shape) and kLangTable's verbosity row 96->120 (the tiling essay moved out of the table body onto the seam above it).

Measured: 10.6% of busy CPU in strcmp leaves on a cold llvm run, 6-12% on four other corpora; 0.23% after. Output byte-identical across 7 corpora x 5 verbs, argvdiffcheck 640/642 vectors identical (the 2 that differ are the +dirty build stamp in --version). WHAT THESE ROWS ARE. (a) 95 short-horizon-churn rows, churn=self: the mechanical rewrite touches essentially every function in ingest_{metrics,binds,sidecap,relations,names}.h, so every one of them shows this lane's own single edit. Not thrash — one commit. (b) 7 duplication rows and 1 new-clone-of-reused-helper. These are REAL new clone groups (--clones, uncapped: 407 groups before, 409 after; the rewrite adds 7 and removes 5) and they are IDIOM COLLISIONS, not copies. kindIs( t, "x" ) is shorter than std::strcmp( t, "x" ) == 0, so short predicate bodies that were previously above the clone threshold now match each other's normalized token stream. Six of the seven pair a node-kind || -chain with an unrelated || -chain over a DISJOINT literal set in a different subsystem — cc_isParamList (tree-sitter parameter-list kinds) against predicatePrefixed (English name prefixes is/has/can), against sliceIsJsPatternKind (JS destructuring kinds), rubyCallIsAssignmentTarget against slice.h's JS binding probes. The tool's own rule is that two ladders over the SAME enum are a copy; these share no non-keyword identifier and no domain, and merging any pair would need a helper parameterised on an unrelated literal table — a wrong abstraction to satisfy a lint. The seventh, kindIs | lexTokenEqualsLowered, is the same shape at 56 tokens with materially different contracts: lexTokenEqualsLowered takes an explicit length and case-folds one side, kindIs takes its length from the literal's type and compares the terminating NUL as an ordinary byte — and that NUL comparison is precisely the safety property kindIs depends on (test/nodekindcheck.sh arm B proves the absence of a read past it with an mprotect(PROT_NONE) guard page). Folding them together would erase the one property being gated. Gate: test/nodekindcheck.sh, 4 arms, 1,348,096 enumerated (candidate, literal) pairs against std::strcmp plus two mutation controls that each turn an arm red.

All seven gating rows are this lane's own footprint on the two cache seams; the three rows that were REAL are FIXED rather than acked (below). (1) api-surface contract-change loadCache 4->5 and runParsePool 7->8. loadCache's old fourth parameter was 'long long& blobWriteNsOut'; it is replaced by the crawled-file list plus a CacheLoadStats out-struct, because the whole point of v15 is that a load deserialises ONLY the records for the files THIS crawl asked for, and a load that is not told the crawl cannot do that. runParsePool takes that same struct through so the RIPWIRE_CACHE_STATS line can report cached_records=/blob_entries= — the two numbers that make band (2) an executable fact instead of a wall-clock claim (test/cacheoffsetcheck.sh check (e)). Both are internal to ingest.cpp's single TU, one call site each, updated in the same commit; no consumer outside the TU ever saw either signature. (2) five short-horizon-churn churn=self rows on kCacheVersion, kIngestCacheVersionMirror, loadCache, saveCache and runParsePool: the footprint of editing exactly the symbols a format bump must edit, in a window that also holds the gate commit. Not thrash — a version constant and its gated mirror must move together in one commit by construction (qextractionkeycheck). WHAT WAS FIXED INSTEAD OF ACKED, because it was real: saveCache's complexity 94->125 and verbosity 285->408 are gone (zero regression) after the seven per-file fact-grouping loops moved to buildCacheFileIndexes, the path/order prologue to buildCachePathKeys, and the plan/carry/trailer work to buildCacheWritePlan/appendCarryRecord/finishCacheBlob; and the duplication row against ingest_sidecap.h TreeGuard::operator= is gone because ReadFd dropped its move-assignment for an openOnce() that fills an empty guard, the only mutation the type needs. Verification at this head: test/cacheoffsetcheck.sh ALL PASS (written RED first at 8411f7e), the whole cache family green, ASan+UBSan+LSan clean on cold store, warm load, subset load and carry-over save on both the fixture and this repo, three-run byte determinism, warm==--no-cache, xmllint clean.

 ack short-horizon-churn 779387a679944627 5 cid=b026f45951caaa1d OPTREMARKS F3 (docs/OPTREMARKS.md §8b): the ~430 per-AST-node std::strcmp( t, "literal" ) sites in the five ingest walk sections become rw::kindIs (src/infra/nodekind.h) — an inline compare, because strcmp is an external symbol LTO cannot inline and on macOS costs two dyld stub hops before it starts. Measured: 10.6% of busy CPU in strcmp leaves on a cold llvm run, 6-12% on four other corpora; 0.23% after. Output byte-identical across 7 corpora x 5 verbs, argvdiffcheck 640/642 vectors identical (the 2 that differ are the +dirty build stamp in --version). WHAT THESE ROWS ARE. (a) 95 short-horizon-churn rows, churn=self: the mechanical rewrite touches essentially every function in ingest_{metrics,binds,sidecap,relations,names}.h, so every one of them shows this lane's own single edit. Not thrash — one commit. (b) 7 duplication rows and 1 new-clone-of-reused-helper. These are REAL new clone groups (--clones, uncapped: 407 groups before, 409 after; the rewrite adds 7 and removes 5) and they are IDIOM COLLISIONS, not copies. kindIs( t, "x" ) is shorter than std::strcmp( t, "x" ) == 0, so short predicate bodies that were previously above the clone threshold now match each other's normalized token stream. Six of the seven pair a node-kind || -chain with an unrelated || -chain over a DISJOINT literal set in a different subsystem — cc_isParamList (tree-sitter parameter-list kinds) against predicatePrefixed (English name prefixes is/has/can), against sliceIsJsPatternKind (JS destructuring kinds), rubyCallIsAssignmentTarget against slice.h's JS binding probes. The tool's own rule is that two ladders over the SAME enum are a copy; these share no non-keyword identifier and no domain, and merging any pair would need a helper parameterised on an unrelated literal table — a wrong abstraction to satisfy a lint. The seventh, kindIs | lexTokenEqualsLowered, is the same shape at 56 tokens with materially different contracts: lexTokenEqualsLowered takes an explicit length and case-folds one side, kindIs takes its length from the literal's type and compares the terminating NUL as an ordinary byte — and that NUL comparison is precisely the safety property kindIs depends on (test/nodekindcheck.sh arm B proves the absence of a read past it with an mprotect(PROT_NONE) guard page). Folding them together would erase the one property being gated. Gate: test/nodekindcheck.sh, 4 arms, 1,348,096 enumerated (candidate, literal) pairs against std::strcmp plus two mutation controls that each turn an arm red.

Every finding of every other kind this round opened was FIXED rather than acked: emitLintSarif's complexity 11->20, verbosity 44->69, params 5->6 and api-surface 5->6 all went back to baseline by extracting writeSarifRuleDecl / writeSarifResult / writeSarifRunProperties and folding the run-level facts into one SarifRunProperties struct instead of a parameter per disclosure; emitRunLintSarif's params 8->12 went back to 8 by taking the MainDispatch every other handler already takes; formatRecallHeader's verbosity 55->67 went back by moving the rationale above the function. What is left is structural: a disclosure gap cannot be closed without editing the verb that has it. pruned_dirs= requires collectSources (the crawl branch that prunes) and runSkipped+kSkippedLegend (the verb and legend that report it) and printUsage (the flag's own help text); the SARIF selection/applicability crossover requires emitRunLintSarif and its runLint call site; the recall lines= clause requires formatRecallHeader.

Subject: [PATCH 64/87] fix(skillsinstall): finish the release-installer gates
 CI caught (dangling-symlink prune, Codex --hook, Claude router, hermes-native
 skills)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR #293's release matrix was red across all 24 shards on nine distinct
gates — not one bug, but several unfinished slices of #225's own plan:

- pruneStale only removed entries the *previous manifest* tracked, so a
  stray/dangling ripwire-* symlink the manifest never recorded (a skill
  removed from disk by hand, or planted by an older installer) lingered
  forever. Now scans destDir directly for ripwire-* symlinks not in the
  current set, same ripwire-* scope-of-authority guard as before (I7).
- `--codex --hook` was a literal "not implemented yet" stub. Ported
  skills/install.sh's pre-#225 install_codex_hook: PreToolUse nudge +
  SessionStart primer + UserPromptSubmit router merged into
  ${CODEX_HOME:-~/.codex}/hooks.json in one jq call, matched by exact
  command (Codex has one install channel, unlike Claude's isScript
  basename match).
- Claude's `--hook` never registered the UserPromptSubmit prompt router
  (install_claude_route was never ported), and the substitution-meter
  disclosure banner (D2) was missing from the C++ path entirely.
- `--hermes` only ever linked the flat ripwire-* set; skills/hermes/
  ripwire-*/ (Hermes-native content, e.g. ripwire-repo-map) was never
  collected, so a real shipped skill silently never installed.
- runJqMergeFile redirected jq's own stderr to /dev/null, so
  codexinstallhonestycheck's "does jq's parse-error diagnostic reach
  stderr" assertion could never pass.

test/routehookcheck.sh and test/codexpromptroutecheck.sh asserted an
installed hook's *exact* checkout path (pre-#225: hooks lived beside a
git checkout). Under #225 the binary always registers its own extracted
store copy, so updated both to match by script basename — the same
"identify by script, not location" convention skills/install.sh's own
jqIsScript already used. hermesinstallcheck.sh arm 7 planted a decoy
skill in a *copy* of skills/ to prove the Hermes-native loop is
ripwire-*-scoped; a copy is no longer a complete installer once skills
are embedded at build time, so it never actually ran. Replaced with a
behavioural check against the real shipped ripwire-repo-map skill plus
a source-level pin on the guard, the same "grep the invariant when no
live repro is constructible" idiom routehookcheck.sh's own D9 arm uses.

collectCurrentSkills extracted out of installForAgent to keep the
latter's complexity from crossing the quality-delta gate; readManifestV2/
ManifestV2 deleted (dead now that pruneStale scans the directory
instead). .ripwire_quality_acks covers the two remaining gating
short-horizon-churn rows (installForAgent, pruneStale) with one reason —
this same commit's own footprint, nothing foreign.

Verified: full pargates suite (655 gates) clean modulo one pre-existing,
unrelated failure (legendcoveragecheck.sh, confirmed red on unmodified
HEAD too); ASan+UBSan+LSan clean; deterministic; xmllint clean;
--quality-delta gating=0.

Short-horizon churn measures edit recency, and these are the edits.
 ack complexity 3561d0281d324276 99 WAVE-2 close (2026-08-19), finding 3 of 3: the 76 remaining gating rows, ONE change. All of them are W2-E's root-relative p= landing (9beaa2c/fccea68/a271e6c/b3fe074 plus the f9108b7 correction), measured for the first time at WAVE granularity. The per-lane acks written during W2-E covered only the correction round's own diff (working-tree-vs-HEAD at that moment), so the original ~30-verb landing was never QD-acked; this ack closes that gap rather than re-accepting anything. Verified by reading the whole 20cdc04..860291c src/main.cpp diff line by line: 282 of 448 added lines match the root-relative predicate directly and every one of the remaining 127 is an existing std::printf rewritten from ing.files[...] to the root-relative rp local, plus four extracted emit helpers (computeDirModules, printJsonSymbolRows, writeOversizeRows, writeDropRows). No unrelated logic rides in. By kind: api-surface 28 = the +1 rootArg/rootPrefix parameter on the emitters that must now be TOLD their root (writeAbiCheck/Ref/Struct, emitColumnar*, packBodies/Deps/Lego/Outline/Signatures[Json], serialize[Json], writeLayout*, packConnect, buildD1Row and the report writers) - defaulted wherever a caller could stay unchanged. complexity 31 and verbosity 16 = the single-root-condition ternary and its guarded root= clause applied per emitter, with no new nesting level and no new control flow beyond that one conditional; the large absolute numbers (runStructureText 207->231, runLint 313->323, runMaintenanceViews 174->190, runCallHierarchy 71->80) are pre-existing dispatcher size the wave adds to, not creates - decomposing them is its own round and is recorded as a wave-2 follow-up. params 1 = writeNonLocalStateReport 4->6, the same contract. The three sibling lanes are individually clean: --quality-delta at f6ec56d..1732fd8 (W2-J), 1732fd8..9a41c74 (W2-K) and 9a41c74..20cdc04 (W2-F) each report gating=0. Full suite green at this head: gates=429 pass=427 skip=2 fail=0, ASan+LSan clean, byte-deterministic, xmllint clean. churn= is unavailable in ref-pair mode by construction (both trees materialized out of the repo), so short-horizon-churn is silent here and that silence is not evidence.

Subject: [PATCH 65/87] fix(test): skillsinstallcheck's idempotent-store arm
 never actually checked mtime on Linux
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`stat -f '%m' FILE 2>/dev/null || stat -c '%Y' FILE` assumes `stat -f`
fails on GNU coreutils so the `-c` fallback fires. It doesn't: GNU's
`-f` is a different, valid flag (filesystem stat, not BSD's format
string), so it succeeds with a multi-line filesystem-info block
instead of erroring. before=/after= were comparing that block's
free-space/inode counters, not the store directory's mtime — stable
enough to pass on an idle machine, but those counters legitimately
drift under concurrent I/O from unrelated processes, so the string
compare spuriously failed under real CI load (confirmed: passed 8/8
alone in a from-scratch Docker repro of the exact ubuntu-24.04/clang/
Release CI leg, then failed 10/10 under added CPU+I/O contention;
the fix passes 10/10 under the identical contention).

test/cachehashcheck.sh already documents this exact coreutils trap and
the house fix (detect the flavour once via `stat --version`, use one
form) — skillsinstallcheck.sh's arm 2 just predates that lesson.

Working through the maintainer's review of #293 item by item:

1. extractGroup no longer trusts the store directory's NAME (a
   content-hash key) alone — storeContentsMatch() lstats it as a real
   directory and byte-compares every embedded file against its store
   copy (O_NOFOLLOW, size then bytes; the reference is already resident
   in the binary, so this costs a read, not a hash). A mismatch —
   missing, a symlink planted at that name, a partial extraction a
   killed run left behind, tampering — re-extracts from scratch through
   the existing tmp+rename path.
2. homeDir() no longer falls back to "/tmp" when HOME is unset; it's
   empty, and every caller refuses instead of silently writing
   somewhere the operator never chose. agentHomeOr() centralizes the
   "${ENV_VAR:-$HOME/suffix}" shape (RIPWIRE_DATA_HOME, CLAUDE_CONFIG_DIR,
   CODEX_HOME) and VALIDATEs each is absolute. wrap.h::resolveSkillsRoot
   gets the same fix at its own "~/" expansion — home + "/.claude/skills"
   with an empty home IS "/.claude/skills", not a caller-visible failure,
   which the caller here (and wrap --all's own listing) depends on.
3. settings.json and the manifest are now written via
   rw::pathguard::createExclTempFile + commit (temp beside the target,
   rename over it) instead of truncate-in-place — a crash mid-write can
   no longer leave either file empty, and commit()'s rename replaces
   whatever sits at the final name, including a symlink, without
   following it.
4. pruneStale reads the previous manifest again (readManifestSkillNames,
   VALIDATEd against the same ripwire-* shape pruneStale's own directory
   scan enforces) and now requires EITHER manifest tracking OR
   pruneTargetIsOurs (dangling, or resolves under dataHome()/"skills")
   before unlinking an untracked name — a user's own symlink that merely
   happens to be named ripwire-<something> is left alone. A
   manifest-tracked name stays prunable regardless of its current
   target, which is what test/skillinstallcheck.sh's own link-safety arm
   already pins.
5. codexdoctor.h::skillsCheck's complexity (3->26, the review's own
   --quality-delta flag) is split: skillsCheckHint now owns the 3-way
   hint-message branching, skillsCheck is fact-gathering only.
6. envOr, byte-identical in codexdoctor.h and skillsinstall.h, moves to
   the new src/infra/envutil.h.
7. A few targeted self-checks per CONTRIBUTING §3: EXPECTS non-empty
   bytes in writeStoreFile (an embedded file is never empty by
   construction), VALIDATE on the manifest's own skill= line shape
   (external, hand-editable input).
8. The stray tracked planning doc
   (.superpowers/sdd/embedded-skills-implementation-plan/fix-wave-2-report.md)
   is removed; the rest of that directory was never tracked.

test/skillsinstallcheck.sh's arm 17 updated: a fully read-only skill
directory cannot support the atomic manifest write's temp+rename either
(needs directory write, same as the symlink() the arm is actually
testing) — the honest outcome is a reported manifest-write failure and
an unchanged manifest, not a silently-wrong count, which was only ever
achievable through the non-atomic write this round replaced on purpose.
test/crashsweepcheck.sh's S2 registry gains storeContentsMatch's one
guarded open, matching every neighbouring entry's shape.

Not done from the review (tracked for a follow-up, not blocking):
worth-doing items 8-13 (--doctor mise/aqualayout mismatch, explicit
0755 on created dirs, usage-text gaps, deferred-until-verified summary
line, non-recursive hooks/ cross-check) and the optional items
(FdGuard/OwnedFd duplication, popen RAII, shimBinaryCheck's ok=1 on an
empty selfPath, a CHANGELOG entry).

Verified: full pargates suite (661 gates) clean modulo the same two
pre-existing/environmental failures confirmed earlier this session
(legendcoveragecheck.sh — red on unmodified main too; pargatescheck.sh
— a timing probe that fails only under -j6 parallel load, passes
alone); ASan+UBSan+LSan clean; deterministic; xmllint clean;
--quality-delta gating=0.

Measured payoff on this repo, --pack-task=rank the call graph: callers 13/20 to 20/20 and fill 52.5% to 59.8% at the default 6000-token budget, 43.5% to 90.6% at 8000; the task-named body now survives every budget increase.

 ack complexity 3d87404c1cdf50ec 27 WAVE-2 close (2026-08-19), finding 3 of 3: the 76 remaining gating rows, ONE change. All of them are W2-E's root-relative p= landing (9beaa2c/fccea68/a271e6c/b3fe074 plus the f9108b7 correction), measured for the first time at WAVE granularity. The per-lane acks written during W2-E covered only the correction round's own diff (working-tree-vs-HEAD at that moment), so the original ~30-verb landing was never QD-acked; this ack closes that gap rather than re-accepting anything. Verified by reading the whole 20cdc04..860291c src/main.cpp diff line by line: 282 of 448 added lines match the root-relative predicate directly and every one of the remaining 127 is an existing std::printf rewritten from ing.files[...] to the root-relative rp local, plus four extracted emit helpers (computeDirModules, printJsonSymbolRows, writeOversizeRows, writeDropRows). No unrelated logic rides in. By kind: api-surface 28 = the +1 rootArg/rootPrefix parameter on the emitters that must now be TOLD their root (writeAbiCheck/Ref/Struct, emitColumnar*, packBodies/Deps/Lego/Outline/Signatures[Json], serialize[Json], writeLayout*, packConnect, buildD1Row and the report writers) - defaulted wherever a caller could stay unchanged. complexity 31 and verbosity 16 = the single-root-condition ternary and its guarded root= clause applied per emitter, with no new nesting level and no new control flow beyond that one conditional; the large absolute numbers (runStructureText 207->231, runLint 313->323, runMaintenanceViews 174->190, runCallHierarchy 71->80) are pre-existing dispatcher size the wave adds to, not creates - decomposing them is its own round and is recorded as a wave-2 follow-up. params 1 = writeNonLocalStateReport 4->6, the same contract. The three sibling lanes are individually clean: --quality-delta at f6ec56d..1732fd8 (W2-J), 1732fd8..9a41c74 (W2-K) and 9a41c74..20cdc04 (W2-F) each report gating=0. Full suite green at this head: gates=429 pass=427 skip=2 fail=0, ASan+LSan clean, byte-deterministic, xmllint clean. churn= is unavailable in ref-pair mode by construction (both trees materialized out of the repo), so short-horizon-churn is silent here and that silence is not evidence.

The gating churn=self row is renderTraceBlock, whose two emitTo format strings are exactly where the name_ladder_capped= attribute has to be written - the file is hot this week, so modifying its emitter at all reads as in-window thrash; nothing was rewritten, two attribute slots were added. partitionTraceFrames 14->16 is the ladder-total plumb (one local + one push into the parallel unresolvedLadderTotal vector). The api-surface rows are the new conditional-disclosure seams (NameLadder, TraceNameBinding, nameLadderAttr/hasNameLadderCut/ladderLegendOf, VerifiedFileRow/verifiedFileRow, kNameLadderLegend, kHandoffSymsCapClause) - all header-inline, all with their own call sites in the same commit. writeHandoffPacket got SMALLER: extracting verifiedFileRow removed its inner symbol loop, so its pre-existing complexity 57 and 240 LOC both fell below baseline instead of growing.

 ack short-horizon-churn 02130bf86f84330f 6 cid=e006e0cc613f2a42 OPTREMARKS F3 (docs/OPTREMARKS.md §8b): the ~430 per-AST-node std::strcmp( t, "literal" ) sites in the five ingest walk sections become rw::kindIs (src/infra/nodekind.h) — an inline compare, because strcmp is an external symbol LTO cannot inline and on macOS costs two dyld stub hops before it starts. Measured: 10.6% of busy CPU in strcmp leaves on a cold llvm run, 6-12% on four other corpora; 0.23% after. Output byte-identical across 7 corpora x 5 verbs, argvdiffcheck 640/642 vectors identical (the 2 that differ are the +dirty build stamp in --version). WHAT THESE ROWS ARE. (a) 95 short-horizon-churn rows, churn=self: the mechanical rewrite touches essentially every function in ingest_{metrics,binds,sidecap,relations,names}.h, so every one of them shows this lane's own single edit. Not thrash — one commit. (b) 7 duplication rows and 1 new-clone-of-reused-helper. These are REAL new clone groups (--clones, uncapped: 407 groups before, 409 after; the rewrite adds 7 and removes 5) and they are IDIOM COLLISIONS, not copies. kindIs( t, "x" ) is shorter than std::strcmp( t, "x" ) == 0, so short predicate bodies that were previously above the clone threshold now match each other's normalized token stream. Six of the seven pair a node-kind || -chain with an unrelated || -chain over a DISJOINT literal set in a different subsystem — cc_isParamList (tree-sitter parameter-list kinds) against predicatePrefixed (English name prefixes is/has/can), against sliceIsJsPatternKind (JS destructuring kinds), rubyCallIsAssignmentTarget against slice.h's JS binding probes. The tool's own rule is that two ladders over the SAME enum are a copy; these share no non-keyword identifier and no domain, and merging any pair would need a helper parameterised on an unrelated literal table — a wrong abstraction to satisfy a lint. The seventh, kindIs | lexTokenEqualsLowered, is the same shape at 56 tokens with materially different contracts: lexTokenEqualsLowered takes an explicit length and case-folds one side, kindIs takes its length from the literal's type and compares the terminating NUL as an ordinary byte — and that NUL comparison is precisely the safety property kindIs depends on (test/nodekindcheck.sh arm B proves the absence of a read past it with an mprotect(PROT_NONE) guard page). Folding them together would erase the one property being gated. Gate: test/nodekindcheck.sh, 4 arms, 1,348,096 enumerated (candidate, literal) pairs against std::strcmp plus two mutation controls that each turn an arm red.

(2) src/ingest.cpp::kLangTable — the extension->grammar rows for .php/.phtml/.lua, plus the extent 37->40 the compiler enforces.

The remaining duplication row (prepare_claude_environment | prepare_codex_environment, 101 tokens, down from 282) is DELIBERATE and not further factored: the residue is 'ephemeral home named by one env var + credentials symlinked + set the var', and collapsing it would need a nine-parameter helper that opencode still could not use (it derives every path from xdg-basedir at module load, so five dirs plus HOME must move). Each preparer is asserted independently by its own canary gate — agentloopclaudecheck/agentloopopencodecheck/agentloopcodexcheck — and keeping the three recipes separately readable is the point of those gates. grade_answers.py's new-symbol rows are the six protocol grader types plus the closed accept-rule clause grammar; apply_clauses is a flat per-clause-kind dispatch with no nesting, and transcript_answer_text's error-masking row is the deliberate 'schema drift degrades to nulls, never raises' contract the retained transcript makes safe. Gates: agentloopgradercheck (new, born red on origin/main at exit 2) and agentloopclaudecheck (new, born red at exit 1) both green; codex/opencode canaries and analyze.py --self-test unchanged and green.

No unrelated logic rides in. By kind: api-surface 28 = the +1 rootArg/rootPrefix parameter on the emitters that must now be TOLD their root (writeAbiCheck/Ref/Struct, emitColumnar*, packBodies/Deps/Lego/Outline/Signatures[Json], serialize[Json], writeLayout*, packConnect, buildD1Row and the report writers) - defaulted wherever a caller could stay unchanged. complexity 31 and verbosity 16 = the single-root-condition ternary and its guarded root= clause applied per emitter, with no new nesting level and no new control flow beyond that one conditional; the large absolute numbers (runStructureText 207->231, runLint 313->323, runMaintenanceViews 174->190, runCallHierarchy 71->80) are pre-existing dispatcher size the wave adds to, not creates - decomposing them is its own round and is recorded as a wave-2 follow-up. params 1 = writeNonLocalStateReport 4->6, the same contract. The three sibling lanes are individually clean: --quality-delta at f6ec56d..1732fd8 (W2-J), 1732fd8..9a41c74 (W2-K) and 9a41c74..20cdc04 (W2-F) each report gating=0. Full suite green at this head: gates=429 pass=427 skip=2 fail=0, ASan+LSan clean, byte-deterministic, xmllint clean. churn= is unavailable in ref-pair mode by construction (both trees materialized out of the repo), so short-horizon-churn is silent here and that silence is not evidence.

-## Per-finding summary
-
-**C3** — `test/hermesinstallcheck.sh` sourced the shared unset helper *after* exporting its own
-`HERMES_HOME`; the helper's blanket unset clobbered it under `set -u`, aborting the gate with
-`HERMES_HOME: unbound variable`. Reordered: source first, export after. Also added a load-bearing
-ordering note to `test/lib/unset-agent-env-variables.sh`'s own header, as asked.
-
-**C1** — `test/skillsinstallcheck.sh`'s `sandbox()` never sourced the shared helper, so an ambient
-`AGENTS_HOME`/`HERMES_HOME`/`CODEX_HOME` would leak past its own `HOME=` for the `--codex`/`--hermes`
-arms. Fixed by sourcing the helper inside `sandbox()`.
-
-**C2** — `test/agenttablecheck.sh` arm (F) bound `HOME`/`AGENTS_HOME`/`CODEX_HOME` per invocation but
-never `HERMES_HOME`, even though `$skillsflag` can be `--hermes`. Added `HERMES_HOME` to that
-invocation's env prefix. Canary sweep (below) then found a **second, unnamed leak** in the same
-file — `RIPWIRE_DATA_HOME`/`CLAUDE_CONFIG_DIR` were never bound at all — fixed by sourcing the
-shared helper once at the top of the file instead of patching the per-invocation prefix again.
-
-**I0** — `test/claudeconfigdircheck.sh` hand-rolled its own `unset CLAUDE_CONFIG_DIR` instead of the
-shared helper, and its `--all` arm (which walks every detected agent) bound none of
-`AGENTS_HOME`/`CODEX_HOME`/`HERMES_HOME`/`RIPWIRE_DATA_HOME`. Replaced the hand-rolled unset with a
-single `source` of the shared helper at the top, covering every arm in the file (not just `--all`).
-
-**M7** — `scripts/verify-agent-integration.sh`'s sandbox branch bound `AGENTS_HOME`/`CODEX_HOME`/
-`CLAUDE_CONFIG_DIR` but not `HERMES_HOME` or `RIPWIRE_DATA_HOME`; `$AGENT` is a free CLI argument, so
-`verify-agent-integration.sh hermes` could write into the operator's ambient `$HERMES_HOME` under a
-"sandbox" banner. Added both vars to both branches (LIVE and sandbox) and to both places they're
-consumed (the install invocation and the `RESOLVED` path-expansion `sh -c`).
-
-Side incident on this same commit: the first version of the M7 comment I wrote pushed the
-`else`-branch's literal `$H/.claude` assignment more than `GUARD_WINDOW=8` lines past the nearest
-real `CLAUDE_CONFIG_DIR` reference in the file, tripping `claudeconfigdircheck.sh` arm (A)'s census
-scan (a genuine regression I introduced and caught before committing — see commit `174dbb8e`).
-Trimmed the comment; arm (A) is green (10/10 sites) after the fix.
-
-**M1** — `test/lib/unset-agent-env-variables.sh`'s header claimed `OPENCLAW_STATE_DIR` is "checked
-ahead of HOME" for openclaw. Verified by grep: no code reads that variable anywhere in `src/`;
-`src/wrap.h` resolves openclaw through a literal `~/.agents/skills` path. Corrected the header to say
-so, and kept `OPENCLAW_STATE_DIR` in the unset list as belt-and-braces (I initially dropped it
-entirely in a first pass — the advisor caught that this was an unrequested isolation weakening, not
-what the task asked for; restored it).
-
-**I4** — `src/skillsinstall.h`'s `dataHome()` reads `RIPWIRE_DATA_HOME` ahead of
-`$HOME/.local/share/ripwire`, and it wasn't in the shared helper's unset list — added.
-`test/installer_isolation.py`'s own separate var tuple (`HOME`, `CODEX_HOME`, `AGENTS_HOME`,
-`HERMES_HOME`) didn't cover `CLAUDE_CONFIG_DIR` or `RIPWIRE_DATA_HOME` either — extended it. Verified
-the two pre-existing failures this gate already surfaces (ghost-symlink prune, Codex `--hook`
-unimplemented — both on the disclosed list) are unchanged before/after the fix, so it introduces no
-new failures.
-
-**I5 / M8 (sourceinstallcheck.sh)** — the case pattern expected the wrap recipe in *double* quotes;
-C3's earlier fix (`rw::shSingleQuote`) made the real output single-quoted, so the pattern could never
-match. Updated to single quotes and reworded the pass/fail messages ("resolves the binary's own
-resolved path", not "the staged Codex installer" — it doesn't resolve a staged file anymore).
-
-**I7 (codexwrapcheck.sh)** — still grepped for the deleted `^bash skills/install\.sh --codex` line.
-Updated to the current `^'[^']+' skills install --codex(...)` shape. (Needed a second pass: my first
-regex used a `$`-anchor that missed the real line's trailing `# deploy to ...` comment — fixed to
-match on whitespace-or-end instead.)
-
-**M3 / I6 (skillsinstallcheck.sh)** — arms 3, 12, 13, 17, 18 redirected stderr to a bare relative
-`skills_install.err` (relative to the `pargates` cwd, the repo root); each arm `rm`'d it on success
-but `fail()` exits immediately, so a failing arm left it in the shared checkout. Redirected each site
-to its own arm's per-arm sandbox dir (`$d3/skills_install.err`, `$d12/skills_install.err`, etc.).
-Verified a full run leaves no `skills_install.err` at repo root.
-
-**M8 (deckcheck_allowlist.txt)** — the `--codex`/`--codex-legacy`/`--hermes` rows still said
-`skills/install.sh's ... destination mode`; reworded to match the `--claude` row's already-correct
-`` `ripwire skills install`'s ... `` wording.
-
-**I1** — `src/skillsinstall.h`'s `installForAgent` had two `!force` `continue` sites (a foreign-but-
-live symlink; non-symlink content at a skill name) that reported nothing — no message, no counter.
-Added `InstallOutcome::foreignSkipped`, incremented at both sites, surfaced as an append-only
-`, M skipped (run --force to relink foreign entries)` suffix on both the bare-command and `--all`
-per-agent summary lines. Kept the existing prefix format string byte-identical so the two known
-consumers — `agenttablecheck.sh`'s `grep -q 'skill(s) linked into'` and
-`verify-agent-integration.sh`'s `sed` extraction of the linked count — are unaffected (both verified
-green). Extended `skillsinstallcheck.sh` arm 3 (which already plants exactly this fixture — a foreign
-live symlink, then a bare install) to assert the skipped-count message, rather than adding a new arm
-19 for a scenario the suite already had a fixture for.
-
-**I2 / I2b** — see "Ambiguous / not fully resolved" below for I2's premise; the fix itself is
-verified working (see empirical check). The manifest-parity hint's `declared < live` branch now
-names the untracked entry directly (`"ripwire-orient exists at this skill home but ... never linked
-it — remove it manually..."`) instead of prescribing `--force`; the `declared > live` branch (a
-manifest-tracked entry that's actually missing from disk, which `--force` genuinely can relink) keeps
-the original hint. I2b: the Codex hook-repair hint printed `run bash skills/install.sh --codex --hook`,
-which now routes into the Codex `--hook` merge refusal (exit 2, no-op) — changed to state plainly
-that Codex hook registration isn't available in this build. Updated `test/codexdoctorcheck.sh:105` to
-match; grepped `test/routehookcheck.sh` too per the advisor's suggestion — it does not consume either
-hint string, so no second gate needed updating.
-
-**I3** — `test/selfcontainedcheck.sh`'s `skills install` arm predated the subcommand's existence and
-had a branch where both success and "acceptable failure" printed `ok`. Now asserts success outright.
-
-**I3b** — `test/wrapverbscheck.sh`'s `assert_skills_line()` greps for two strings deleted from
-`src/wrap.h` 40+ commits ago (`bash skills/install.sh`, `skills not found locally`); those greps are
-correctly-still-negative (they should never match, and don't) — on inspection they were not vacuous
-the way the review described, they're legitimate "this old thing is gone" checks running alongside a
-real positive-shape assertion the function already had. What *was* genuinely degraded: the mise/aqua
-fixture arms only asserted a generic `^'[^']+' skills install...` shape, which matches *any*
-single-quoted path, when their whole purpose is to prove the recipe names the shim's own resolved
-target. Added an exact-string assertion for both (`$MISE_INSTALL/ripwire`, `$AQUA_INSTALL/ripwire`),
-built against `REAL_TMP` (`pwd -P`) rather than `$TMP` directly — `$TMP` and its canonical form differ
-as strings on macOS (`/var/folders/...` vs `/private/var/folders/...`), the same gotcha
-`sourceinstallcheck.sh` already works around. Removed the two stale "RED until wrapPrintSkillsLine is
-rewritten" header comments.
-
-**I3d (doctorstalecheck.sh)** — arm (a) had only a negative assertion (`claude-binary` row is not
-`ok="0"`) with no positive counterpart; added `ok="1"` as the paired positive. The gate's own header
-claims "must never execute anything to figure that out" but nothing grepped the shim fixture's
-sentinel string (`"this is a shim, not the real binary — must never be executed by --doctor"`); added
-that grep, failing if the sentinel ever appears. Also added `trap 'rm -rf "$d"' EXIT` inside
-`sandbox()` (previously each arm's temp dir only got cleaned by its own trailing `rm -rf`, which
-`fail()`'s immediate `exit 1` would skip), and sourced the shared unset helper in `sandbox()` (it
-only bound `HOME`/`CLAUDE_CONFIG_DIR` before).
-
-**I3c** — `INSTALL.md` claimed `./install.sh` (the source build) "activates the skills ... skills and
-hooks are embedded in the ripwire binary itself, not staged as separate files." Verified false:
-`CMakeLists.txt` still stages `skills/` and `hooks/` under `<prefix>/share/ripwire/`, and `install.sh`
-still resolves and runs that staged `skills/install.sh` (`test/sourceinstallcheck.sh` asserts the
-staging exists). Rewrote the paragraph to describe each installer accurately: `./install.sh` stages
-and runs the staged script; `scripts/install.sh` (the prebuilt/release installer) is the one with
-skills and hooks embedded, nothing staged. Also aligned the `RIPWIRE_NO_ACTIVATE=1` wording with
-`scripts/install.sh`'s own message ("skills not activated" — there's nothing to stage on that route).
-
-**M9** — `scripts/install.sh` printed `Optional advisory hooks: ...` unconditionally, even after
-`skills install --all` reported `0 agent(s) configured`. Now captures that command's output, still
-prints it verbatim, and only shows the hooks hint when the parsed `N agent(s) configured` count is
-`> 0`; otherwise prints "Nothing was activated — no detected agent to hook into." Verified against
-`test/releaseinstallcheck.sh` arms (E1)-(E7), all green; grepped for any gate consuming the old
-unconditional string — none found.
-
-## Additional findings, beyond the review's named list
-
-The canary leak-sweep (below) found two more `RIPWIRE_DATA_HOME` leaks the review did not name, in
-gates that were not among the seven the review said already source the shared helper:
-
-- `test/codexdoctorcheck.sh` — binds `HOME`/`CODEX_HOME`/`AGENTS_HOME` per invocation but never
-  touched `RIPWIRE_DATA_HOME`; an ambient one leaked a full store extraction into the canary.
-- `test/selfcontainedcheck.sh` — its `skills install` arm (the one rewritten for I3) hits the same
-  `dataHome()` path with no override.
-
-Both fixed the same way as I4/C2: source the shared helper once near the top of the file. Verified
-clean by re-running the canary sweep after the fix (see below).
-
-## Empirical leak-verification (canary sweep)
-
-Method: pre-create five canary directories (`claude/`, `codex/`, `agents/`, `hermes/`, `data/`) under
-one `mktemp -d`, point `CLAUDE_CONFIG_DIR`/`CODEX_HOME`/`AGENTS_HOME`/`HERMES_HOME`/`RIPWIRE_DATA_HOME`
-at them (pre-created, per the advisor's correction — an unpopulated canary that doesn't exist yet
-would make `--all`'s agent-detection skip it and falsely read as "clean"), run the gate, then
-`find <canary-root> -mindepth 1`. **Caveat**: the five pre-created empty directories themselves always
-appear in that `find` output — "clean" means nothing was written *inside* them, not that the listing
-is empty.
-
-Ran against every gate touched this session:
-
-| Gate | Result |
-| --- | --- |
-| `hermesinstallcheck.sh` | clean (5 empty shells only) |
-| `skillsinstallcheck.sh` | clean |
-| `agenttablecheck.sh` | clean *after* the `RIPWIRE_DATA_HOME`/`CLAUDE_CONFIG_DIR` fix (dirty before — this is how that second leak was found) |
-| `claudeconfigdircheck.sh` | clean |
-| `routehookcheck.sh` | clean |
-| `doctorstalecheck.sh` | clean |
-| `codexdoctorcheck.sh` | clean *after* fix (dirty before — full store extraction into the canary `data/` dir) |
-| `selfcontainedcheck.sh` | clean *after* fix (dirty before, same shape) |
-| `wrapverbscheck.sh` | clean |
-
-`installer_isolation.py` (I4) uses its own sentinel-snapshot method (not the canary-dir sweep, since
-it already does an equivalent-but-stricter check via byte/permission snapshots of seeded homes);
-verified separately by confirming the two pre-existing failures it surfaces are unchanged before and
-after the fix (see I4 above).
-
-`verify-agent-integration.sh` (M7) was verified by direct invocation (`bash
-scripts/verify-agent-integration.sh codex`) rather than the canary sweep — it's an interactive/manual
-tool, not a `test/*check.sh` gate `pargates` runs — confirming no `set -u` unbound-variable error and
-correct output.
-
-## Gate suite result
-
-`python3 test/pargates.py . ./build/ripwire -j 6` — run against a `--clean-first` rebuild of the
-final commit. See the appended summary below once the background run completes (the run exceeded the
-120s foreground timeout in this session and was moved to background monitoring).
-
-Reds observed this session, individually confirmed pre-existing (bisected against the commit
-immediately before this fix wave, `4acc5f3d`, running the SAME binary — not attributed by
-resemblance):
-
-- `skillinstallcheck.sh` / `releaseinstallcheck.sh`: "install.sh did NOT prune a dangling
-  ripwire-ghost symlink" and "--codex --hook did not create ~/.codex/hooks.json" — both on the
-  disclosed list (the deliberately-red ghost-prune assertion; Codex `--hook` merge unimplemented).
-- `routehookcheck.sh`: 5 failures, all naming `UserPromptSubmit`/router registration
-  (`I2 install: no UserPromptSubmit entry...`, `I3 install: 0 router entries...`, `I3b`, `I6`, `V2
-  doctor: route_hook is not 1`) — all on the disclosed list ("UserPromptSubmit routing hook not
-  wired"). Confirmed pre-existing by running the exact `4acc5f3d` copy of this file (in `test/`, via
-  `bash`, not a bare invocation — see caveat below) against the current binary: identical 5 failures.
-- `agenttablecheck.sh` arm (K) — was failing before this session's work (disclosed: "ambient-env
-  artifact"); after the `RIPWIRE_DATA_HOME`/`CLAUDE_CONFIG_DIR` fix to this same file (for the C2
-  leak, not for arm K), it now passes as a side effect of no longer leaking ambient env into the
-  gate's own detection logic. **I did not touch arm (K)'s assertion or logic** — flagging this
-  explicitly so a reviewer doesn't read the flip as an unauthorized fix to a disclosed, do-not-touch
-  item.
-- **hermesinstallcheck.sh — 5 failures, all newly *visible* because of the C3 fix, not newly
-  introduced.** At `4acc5f3d` (before C3), the gate died after ~3 arms with 2
-  `HERMES_HOME: unbound variable` errors and never reached the arms below that point. After the
-  reorder, the gate runs to completion and 5 arms fail:
-  `--hermes exposed 16 of 17 skills`, `--hermes manifest set differs (15 vs 17)`, `a default (Claude)
-  install overwrote/pruned the Hermes skill home (found=16)`, `the Hermes-native loop did not link
-  the planted ripwire-decoy-map`, `the --hermes manifest omits ripwire-decoy-map`. I traced all five
-  to one cause: `shipped=17` counts `skills/hermes/ripwire-repo-map` (a real Hermes-native skill in
-  the repo) plus the 16 flat skills, but the Hermes-native linking loop never actually links it — the
-  disclosed gap "Hermes-native selection unported." The first three failures are the same
-  16-vs-17 undercount surfacing three times (fresh install, post-Claude-install re-check, and the
-  manifest-set diff); the last two are a separate arm (7) that plants a *synthetic* Hermes-native
-  fixture (`ripwire-decoy-map`, its own SKILL.md, its own throwaway home) and asserts it gets linked.
-  Both arms 1 and 7 go through the identical code path — `skills/install.sh` is now a thin wrapper
-  (`exec "$ripwire_bin" skills install "$@"`, confirmed by reading it), so there is no separate
-  "shell installer" logic left to blame here, only `ripwire skills install --hermes` itself. One real
-  repo skill and one purpose-built fixture skill, reached through the same wrapper into the same
-  binary subcommand, both fail to link — that is the signature of the native-selection loop not
-  running at all, not a fluke or a fixture bug, which is why I'm treating all 5 as one disclosed root
-  cause rather than 5 separate opens. **This gate is now more red than it was before this fix wave,
-  and that is expected and correct**: the previous 2-error state was masking these 5 with a crash,
-  not fixing them. C3's job was to stop the crash, not to fix Hermes-native selection (out of scope,
-  disclosed, not attempted).
-
-*(Caveat on the routehookcheck baseline comparison above: my first attempt at this comparison copied
-the file to `/tmp` and ran it without `bash`, which silently failed with "permission denied" — a
-non-executable file invoked directly — and I misread the resulting empty grep as "0 failures,
-therefore pre-existing." I caught this from the exit code before drawing any conclusion from it, and
-redid it correctly: copied into `test/` so `$0`-relative `ROOT` resolution stays correct, invoked
-explicitly via `bash` to bypass the missing +x bit. The corrected comparison is what's reported
-above.)*
-
-## Ambiguous / not fully resolved — reported honestly
-
-**I2(a)'s stated premise does not reproduce in either scenario I tested.** The review states the
-manifest-parity row's `ok` "never goes false for a foreign symlink (it reads ok=\"1\" — blind)". I
-worked through the logic before writing the fix and concluded the opposite: `manifest.declared`
-(built from `linkedNames`, which excludes a skipped foreign entry) and `live` (built by
-`liveSkills()`'s `is_directory()`, which follows the symlink and counts it) should differ in both
-size and membership whenever a foreign symlink is skipped — which should make `parity` false and
-`ok` false, not blind. I ran the advisor's suggested empirical check twice (plant a foreign symlink
-into a live directory under a sandboxed `HOME`, run bare `skills install`, then
-`--doctor --agent=claude`) — once against a fresh skill home, once against a home with a prior
-successful install before the symlink swap — and both times got:
-
-```
-<c n="claude-skills" ok="0" manifest="1" declared="15" live="16" hint="ripwire-orient exists at this
-skill home but ripwire skills install --claude never linked it — remove it manually if it is not
-meant to be there"/>
-```
-
-`ok="0"` both times, not blind. I have not found or reproduced a scenario matching the review's
-literal "ok=1 for a foreign symlink" claim. My fix (the `declared < live` branch naming the untracked
-entry) is verified correct and produces the intended, more-honest hint in both scenarios I tried — so
-the deliverable is empirically sound regardless of which premise is right. But I'm flagging the
-discrepancy rather than silently assuming either the review or my derivation is wrong: it's possible
-the review's repro used a different construction (e.g. a *dangling* foreign symlink prior to some
-other code path, or a manifest v1 upgrade path I didn't try) that does hit a blind case I haven't
-found. If that's true, my fix's `declared < live` condition would simply never fire for that specific
-sub-case (falling through to the unchanged `declared > live` branch's `--force` hint) rather than
-being wrong — but I can't confirm that without knowing the exact repro the review used.
-
-**`test/releaseinstallcheck.sh:129` and its arm (E5) PASS line repeat the same false claim I3c fixed
-in INSTALL.md**: the comment says "RIPWIRE_NO_ACTIVATE=1 stages without activating" for
-`scripts/install.sh` (the release installer), which stages nothing — I verified this directly while
-fixing I3c. This is a test comment/message, not user-facing documentation, and wasn't named in the
-review's fix list, so I left it as found-but-not-fixed rather than expanding scope. Flagging with the
-exact location: `test/releaseinstallcheck.sh:129` (comment) and the `(E5)` `ok` message at line ~213.
-
-**ASan/UBSan tree** — not run, per the task's own instruction that it's optional/time-permitting and
-not required to complete this wave. Not attempted.
-
-## Skipped, per explicit instruction
-
-M2, M4, M5, M6, the `pargatescheck.sh`/`strkerncheck.sh`/`taskroutecheck.sh` timing items, and
-everything on the prior fix-wave's already-disclosed list — untouched, as instructed.

Subject: [PATCH 67/87] fix(embed): make hooks/ embed step recursive (review
 item 13)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CMakeLists.txt globbed hooks/*.sh with a plain GLOB — one directory level
only — while skills/*.md already used GLOB_RECURSE. A hooks/lib/x.sh would
silently never reach generated/embedded_skills.h, and
test/selfcontainedcheck.sh's own cross-check used the identically shallow
hooks_dir.glob('*.sh'), so it could never catch the gap either.

Switched the CMake glob to GLOB_RECURSE and the Python cross-check to
rglob(). New test/hooksembedrecursivecheck.sh configures a scratch git
worktree with a synthetic hooks/lib/x.sh and asserts it lands in the
generated header — exercising the real CMakeLists.txt call, not a
duplicated toy, without ever touching the real working tree.

Gate count 646->647 via docs/gatecount_build.py; pargates weight added.

Three related gaps, all closed the same way: bare `ripwire skills` fell
through to parseArgs, which mapped the skills/ directory as a crawl root
(exit 0, dumps the corpus map) since it happens to exist in this checkout;
`skills install --help`/`-h` hit the unknown-flag branch and refused with
exit 2; and top-level `--help` never mentioned `skills install` at all.

Added printSkillsInstallHelp/printSkillsUsage (src/skillsinstall.h), wired
bare `ripwire skills` in main.cpp to the latter, and added a usage-preamble
line in cli.h next to the existing `ripwire wrap <agent>` one. Kept the
preamble line free of bare lowercase --flag tokens (a first attempt with
`--all` written out made flagsurfacecheck.sh's --help=all scrape report
--all as advertised-but-unparsed — it's skills install's own flag, not a
top-level one) by pointing at `skills install --help` for the flag catalog
instead of enumerating it in the one-line summary.

test/skillsinstallcheck.sh arms 19-20 pin both fixes; ack added for a
spurious duplication finding (printSkillsInstallHelp's single
emitRaw(literal) body structurally collides with printEvalRankerNote's —
same idiom as the existing symlinkOrRefuse|extentsuspect.h::inSet ack).

All of them are W2-E's root-relative p= landing (9beaa2c/fccea68/a271e6c/b3fe074 plus the f9108b7 correction), measured for the first time at WAVE granularity. The per-lane acks written during W2-E covered only the correction round's own diff (working-tree-vs-HEAD at that moment), so the original ~30-verb landing was never QD-acked; this ack closes that gap rather than re-accepting anything. Verified by reading the whole 20cdc04..860291c src/main.cpp diff line by line: 282 of 448 added lines match the root-relative predicate directly and every one of the remaining 127 is an existing std::printf rewritten from ing.files[...] to the root-relative rp local, plus four extracted emit helpers (computeDirModules, printJsonSymbolRows, writeOversizeRows, writeDropRows). No unrelated logic rides in. By kind: api-surface 28 = the +1 rootArg/rootPrefix parameter on the emitters that must now be TOLD their root (writeAbiCheck/Ref/Struct, emitColumnar*, packBodies/Deps/Lego/Outline/Signatures[Json], serialize[Json], writeLayout*, packConnect, buildD1Row and the report writers) - defaulted wherever a caller could stay unchanged. complexity 31 and verbosity 16 = the single-root-condition ternary and its guarded root= clause applied per emitter, with no new nesting level and no new control flow beyond that one conditional; the large absolute numbers (runStructureText 207->231, runLint 313->323, runMaintenanceViews 174->190, runCallHierarchy 71->80) are pre-existing dispatcher size the wave adds to, not creates - decomposing them is its own round and is recorded as a wave-2 follow-up. params 1 = writeNonLocalStateReport 4->6, the same contract. The three sibling lanes are individually clean: --quality-delta at f6ec56d..1732fd8 (W2-J), 1732fd8..9a41c74 (W2-K) and 9a41c74..20cdc04 (W2-F) each report gating=0. Full suite green at this head: gates=429 pass=427 skip=2 fail=0, ASan+LSan clean, byte-deterministic, xmllint clean. churn= is unavailable in ref-pair mode by construction (both trees materialized out of the repo), so short-horizon-churn is silent here and that silence is not evidence.
 ack complexity 8d58de9bb922f582 43 T1 completeness claims (complete= on grep/whereis): the +1 on streamBlobs is the deliberate DEFAULTED StreamBlobStats* param (null-object sink inside, no per-site null test; every existing caller byte-identical) so whereis can prove its scan exhaustive before claiming; cx/LOC on streamBlobs/computeWhereis/writeWhereisPage/emitGrepReport is the claim computation plus its in-band legend (the honesty text IS the feature); churn=self on those plus grepCollect/dispatchMcpLine is this lane own edit window.

Each is the disclosure plus its ceiling arithmetic, pinned by estchargecheck/truncvocabcheck/collectioncapcheck/floormarkcheck | prior: R-E CORRECTION lane (2026-08-19), the W2-E root-relative fix round. Every row here belongs to ONE change with one purpose: the 2026-08-17 R-E landing emitted root-relative p= on ~30 verbs, defined root= in NO legend, converted the CLI arm of exemplar/impact/uses/owners/cochange/mentions/find_symbol and not the MCP twin, appended root= AFTER at= (breaking the r26 at=-stays-LAST rule --owners own emitter comment states), and left three verbs (--exemplar, --lego, --expand) serving relative paths against a root they never named. Full suite green at the end: gates=429 pass=427 skip=2 fail=0, ASan+LSan clean, byte-deterministic x3, xmllint clean. api-surface: kRootRelPathsLegend/rootRelPathsLegend are the ONE shared definition of root=, hoisted rather than pasted into eighteen legends (the S B4 echo-site rule); connectEstTokens gains an extraBytes param (1 to 2) because the first landing put root= in the connect start tag and left the estimator alone, i.e. the exact under-report kConnectRootBytes own comment forbids, and both the trim-loop fit check and the printed est_tokens must read the SAME number so it is passed, never re-derived. complexity: exemplarText 14 to 18, usesText 23 to 27, runDefaultMap 191 to 197, serialize 190 to 191, runTargetedViews 37 to 39 — every point is the single-root-condition ternary the CLI arm already carries at twenty-plus sites, applied to the twin so the two surfaces cannot answer one question in two path dialects; no new nesting level and no new control flow beyond that one conditional. verbosity: the added lines are overwhelmingly the WHY comments this repo requires on a re-pin or a degrade path, plus the guarded root= clause; no new logic rides in them. short-horizon-churn: churn=self on every symbol this correction edited is this one edit window, the same shape the two --lint acks above record and for the same reason. No duplication, dead-code, error-masking, param or reuse-decline finding appears in this report.
 ack complexity 92ac9caf38b8aab0 20 root-relative coverage round (verifier E1-E4 + two gaps the widened gate exposed, 2026-08-19): every gating row here is the SAME three-line pattern every verb in the original root-relative round already pays — a singleRoot bool, a rootPrefix, a rootAttr, and one ternary per path emission (the shape clones/prcontext/situ/mcp-path all carry verbatim). --tree (runStructureText) +8 ccx / +13 LOC and --quality-panel (writePanelReport) +4 ccx / +12 LOC are those lines plus the finding comment; forTaskText and packTaskBundleText are argument threading only. packBodiesJson api-surface 3 to 4 params is a DELIBERATE contract change: a defaulted trailing rootArg, identical in name, position and default to the one packSignatures/packBodies/packLego/packOutline already take, so the emitter family stays one shape and every existing call site is unaffected. churn=self/ambient is this change's own edit window. Payoff: 1340 absolute paths removed from four surfaces (tree 1212, analyze 85, panel 40, mcp-for 3) plus 5 in the pack-task JSON tail that the gate had been scoring on an empty document, and every single-root run now discloses its root exactly once. All red-first in test/rootrelcheck.sh
 ack complexity 949f0a5b0ae79ca0 29 cid=b9354baf0556cc75 scopeless-fold lane: the five gating rows are the new mechanism itself, read one by one. (1) remapAckIdentity complexity 26->29: it resolves THREE rescue routes now (rename, content, and the 2026-08-25 key-scheme replay) where it resolved two; the growth is one route-selection ternary plus a third switch arm, and collapsing them would hide WHICH mechanism moved an ack, which is the disclosure this round exists to provide. A branchless array tally was tried and measured identical, so it bought nothing. (2)+(4) qualityKey pairs with resolve.h::canonicalIdRelTo: the similarity is deliberate and load-bearing. They take the same (ing, symbol, root) and differ ONLY in which identity question they answer - canonicalIdRelTo builds the ENTITY id (path::scope::name, which must keep folding the 21 extern-C tree_sitter_X declarations into the one C function they actually are), qualityKey builds the SOURCE key (pathQualifiedKey, which must not fold anything). Merging them would re-create the exact bug this lane fixed. (3)+(5) baselineHeaderIsForeign pairs with crossref::isNullSha at 32 tokens: a shape match between two unrelated three-line string predicates, not shared behaviour. It was extracted precisely BECAUSE the tool objected to the same logic inline in readBaseline; there is no third spelling that satisfies both.

 ack short-horizon-churn 2467c48e0842da91 13 cid=9b69f827943239f7 OPTREMARKS F3 (docs/OPTREMARKS.md §8b): the ~430 per-AST-node std::strcmp( t, "literal" ) sites in the five ingest walk sections become rw::kindIs (src/infra/nodekind.h) — an inline compare, because strcmp is an external symbol LTO cannot inline and on macOS costs two dyld stub hops before it starts. Measured: 10.6% of busy CPU in strcmp leaves on a cold llvm run, 6-12% on four other corpora; 0.23% after. Output byte-identical across 7 corpora x 5 verbs, argvdiffcheck 640/642 vectors identical (the 2 that differ are the +dirty build stamp in --version). WHAT THESE ROWS ARE. (a) 95 short-horizon-churn rows, churn=self: the mechanical rewrite touches essentially every function in ingest_{metrics,binds,sidecap,relations,names}.h, so every one of them shows this lane's own single edit. Not thrash — one commit. (b) 7 duplication rows and 1 new-clone-of-reused-helper. These are REAL new clone groups (--clones, uncapped: 407 groups before, 409 after; the rewrite adds 7 and removes 5) and they are IDIOM COLLISIONS, not copies. kindIs( t, "x" ) is shorter than std::strcmp( t, "x" ) == 0, so short predicate bodies that were previously above the clone threshold now match each other's normalized token stream. Six of the seven pair a node-kind || -chain with an unrelated || -chain over a DISJOINT literal set in a different subsystem — cc_isParamList (tree-sitter parameter-list kinds) against predicatePrefixed (English name prefixes is/has/can), against sliceIsJsPatternKind (JS destructuring kinds), rubyCallIsAssignmentTarget against slice.h's JS binding probes. The tool's own rule is that two ladders over the SAME enum are a copy; these share no non-keyword identifier and no domain, and merging any pair would need a helper parameterised on an unrelated literal table — a wrong abstraction to satisfy a lint. The seventh, kindIs | lexTokenEqualsLowered, is the same shape at 56 tokens with materially different contracts: lexTokenEqualsLowered takes an explicit length and case-folds one side, kindIs takes its length from the literal's type and compares the terminating NUL as an ordinary byte — and that NUL comparison is precisely the safety property kindIs depends on (test/nodekindcheck.sh arm B proves the absence of a read past it with an mprotect(PROT_NONE) guard page). Folding them together would erase the one property being gated. Gate: test/nodekindcheck.sh, 4 arms, 1,348,096 enumerated (candidate, literal) pairs against std::strcmp plus two mutation controls that each turn an arm red.

The remaining duplication row (prepare_claude_environment | prepare_codex_environment, 101 tokens, down from 282) is DELIBERATE and not further factored: the residue is 'ephemeral home named by one env var + credentials symlinked + set the var', and collapsing it would need a nine-parameter helper that opencode still could not use (it derives every path from xdg-basedir at module load, so five dirs plus HOME must move). Each preparer is asserted independently by its own canary gate — agentloopclaudecheck/agentloopopencodecheck/agentloopcodexcheck — and keeping the three recipes separately readable is the point of those gates. grade_answers.py's new-symbol rows are the six protocol grader types plus the closed accept-rule clause grammar; apply_clauses is a flat per-clause-kind dispatch with no nesting, and transcript_answer_text's error-masking row is the deliberate 'schema drift degrades to nulls, never raises' contract the retained transcript makes safe.

Subject: [PATCH 69/87] fix(doctor): mise/aqua resolvers match REAL install
 layouts (review item 8)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

resolveMiseLayout hardcoded <version>/bin/ripwire — mise's real layout,
confirmed against test/wrapverbscheck.sh's own fixtures, is
<version>/<archive-name>/ripwire with no "bin/" at all. resolveAquaLayout's
root was pkgs/redhat-et/ripwire, missing aqua's own
github_release/github.com/ registry/host prefix, and only searched one
level of nesting when a real aqua install nests two
(<version>/<archive>.tar.gz/<archive>/ripwire). Every real install of
either manager reported managed_unverified="1" — recognised as a shim,
but the layout it pointed at never resolved.

Replaced both hardcoded-shape functions with one
resolveManagerVersionLayout that recursively searches (bounded depth 8,
non-throwing) for a file named exactly "ripwire" under the single
resolved version directory, requiring exactly one match — same
ambiguous/no-candidate contract as before, but shape-agnostic, so it
doesn't rot the next time either manager repackages its archives.

New arms d/e in test/doctorstalecheck.sh pin both real layouts against a
copied-binary fixture. Fixed a latent bug in the process: arms a/b/(now
d/e)'s managed_unverified assertions grepped the WHOLE --doctor output,
which always contains that string in the legend's own prose explaining
the attribute — scoped all four to the claude-binary row specifically.

Subject: [PATCH 70/87] fix(skillsinstall): 0755 directory creation, jq PATH
 pinning + stale comment (review items 9, 10)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Item 9: create_directories() on POSIX creates 0777-masked-by-umask, so a
permissive umask (000) left a freshly created store/skills/settings
directory world-writable. createDirectoriesMode0755 now walks the path
one level at a time (create_directories()'s own "created" bool only
reports the LEAF of a multi-level create — extractGroup's tmp extraction
directory, later renamed into place as the store root, is an
INTERMEDIATE level of exactly that shape, and the first version of this
fix missed it) and forces every level it actually creates to 0755. A
pre-existing directory anywhere in the chain is left untouched.

Item 10: fixed the stale comment claiming the hook-merge jq command
redirects its own stderr to /dev/null (it doesn't — only the unrelated
jqScriptAlreadyRegistered probe does; the merge's stderr is left to
inherit the caller's, which codexinstallhonestycheck.sh already pins).
Added resolveJqPath() (same PATH-walk shape as codexdoctor.h's
resolveExecutable) and pinned both jq call sites to its resolved
absolute path instead of a bare "jq" token left for /bin/sh to resolve.

New arm 21 in skillsinstallcheck.sh proves 0755-under-umask-000 for both
the skills destination and the store directory. New arms F/G in
skillinstallcheck.sh prove --hook resolves jq via an actual PATH walk
(a wrapper placed first on PATH is the one that runs) and fails cleanly,
naming jq, when none is anywhere on PATH.

Measured: 10.6% of busy CPU in strcmp leaves on a cold llvm run, 6-12% on four other corpora; 0.23% after. Output byte-identical across 7 corpora x 5 verbs, argvdiffcheck 640/642 vectors identical (the 2 that differ are the +dirty build stamp in --version). WHAT THESE ROWS ARE. (a) 95 short-horizon-churn rows, churn=self: the mechanical rewrite touches essentially every function in ingest_{metrics,binds,sidecap,relations,names}.h, so every one of them shows this lane's own single edit. Not thrash — one commit. (b) 7 duplication rows and 1 new-clone-of-reused-helper. These are REAL new clone groups (--clones, uncapped: 407 groups before, 409 after; the rewrite adds 7 and removes 5) and they are IDIOM COLLISIONS, not copies. kindIs( t, "x" ) is shorter than std::strcmp( t, "x" ) == 0, so short predicate bodies that were previously above the clone threshold now match each other's normalized token stream. Six of the seven pair a node-kind || -chain with an unrelated || -chain over a DISJOINT literal set in a different subsystem — cc_isParamList (tree-sitter parameter-list kinds) against predicatePrefixed (English name prefixes is/has/can), against sliceIsJsPatternKind (JS destructuring kinds), rubyCallIsAssignmentTarget against slice.h's JS binding probes. The tool's own rule is that two ladders over the SAME enum are a copy; these share no non-keyword identifier and no domain, and merging any pair would need a helper parameterised on an unrelated literal table — a wrong abstraction to satisfy a lint. The seventh, kindIs | lexTokenEqualsLowered, is the same shape at 56 tokens with materially different contracts: lexTokenEqualsLowered takes an explicit length and case-folds one side, kindIs takes its length from the literal's type and compares the terminating NUL as an ordinary byte — and that NUL comparison is precisely the safety property kindIs depends on (test/nodekindcheck.sh arm B proves the absence of a read past it with an mprotect(PROT_NONE) guard page). Folding them together would erase the one property being gated.

From 11add07e7a993daac9c521aa34cdbf605f860210 Mon Sep 17 00:00:00 2001
From: Pedro Algarvio <pedro@algarvio.me>

Subject: [PATCH 71/87] fix(doctor): shimBinaryCheck no longer claims
 same_file="0" it never computed (review item 3, optional)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

An empty selfPath (this process's own executable path could not be
determined) made shimBinaryCheck report ok=1 same_file="0" — a
comparison that never ran, indistinguishable in the output from a real
comparison that found the files different-but-tolerated. Now reports
self_unverified="1" instead, with no same_file= attribute at all,
matching the "disclosed unknown, not a failure" shape the ambiguous
managed_unverified="1" branch two lines below it already uses. Legend
text in verbs_doctor.h documents the new attribute alongside it.

New test/shimselfunverifiedcheck.sh compiles codexdoctor.h standalone
(same pattern selfcontainedcheck.sh already uses for embedded_skills.h)
and calls shimBinaryCheck("") directly against a real single-candidate
mise fixture, sidestepping the OS-specific question of how
selfExecutablePath() itself ever comes back empty in a live run.

Gate count 647->648.

All seven gating rows are this lane's own footprint on the two cache seams; the three rows that were REAL are FIXED rather than acked (below). (1) api-surface contract-change loadCache 4->5 and runParsePool 7->8. loadCache's old fourth parameter was 'long long& blobWriteNsOut'; it is replaced by the crawled-file list plus a CacheLoadStats out-struct, because the whole point of v15 is that a load deserialises ONLY the records for the files THIS crawl asked for, and a load that is not told the crawl cannot do that. runParsePool takes that same struct through so the RIPWIRE_CACHE_STATS line can report cached_records=/blob_entries= — the two numbers that make band (2) an executable fact instead of a wall-clock claim (test/cacheoffsetcheck.sh check (e)). Both are internal to ingest.cpp's single TU, one call site each, updated in the same commit; no consumer outside the TU ever saw either signature. (2) five short-horizon-churn churn=self rows on kCacheVersion, kIngestCacheVersionMirror, loadCache, saveCache and runParsePool: the footprint of editing exactly the symbols a format bump must edit, in a window that also holds the gate commit. Not thrash — a version constant and its gated mirror must move together in one commit by construction (qextractionkeycheck). WHAT WAS FIXED INSTEAD OF ACKED, because it was real: saveCache's complexity 94->125 and verbosity 285->408 are gone (zero regression) after the seven per-file fact-grouping loops moved to buildCacheFileIndexes, the path/order prologue to buildCachePathKeys, and the plan/carry/trailer work to buildCacheWritePlan/appendCarryRecord/finishCacheBlob; and the duplication row against ingest_sidecap.h TreeGuard::operator= is gone because ReadFd dropped its move-assignment for an openOnce() that fills an empty guard, the only mutation the type needs. Verification at this head: test/cacheoffsetcheck.sh ALL PASS (written RED first at 8411f7e), the whole cache family green, ASan+UBSan+LSan clean on cold store, warm load, subset load and carry-over save on both the fixture and this repo, three-run byte determinism, warm==--no-cache, xmllint clean.

 ack short-horizon-churn e0a00f3a5f72168d 22 cid=8df40da9967f24e3 by=src/* rung 3 flow-sensitive reaching definitions (docs/EVALS.md 'Flow-sensitive slice in the small', 2026-09-03, lane/n6-b). edgesOf: the contract change IS the point — the diff now reads the scan's reach table (scan, rowOfOcc, cap) so rows/flow/diff share one edge oracle. sliceEmitBody +4 cx: the rd= emission per use row (its formatting already factored into sliceAppendReachAttr). The three duplication rows are the idiomatic tree-sitter named-child loop (seq/hasStructureBelow vs ingest helpers) and a two-way family ternary — no shared logic to lift. short-horizon-churn = self-churn of the two files this lane owns. sliceLegendText +11 lines = the registered per-construct disclosures the band requires on the first screen.
 ack short-horizon-churn e14feca13c7ae680 13 cid=3f37ac1bf2682450 Review of #214, round 2. The <tests> section now cuts over its own grouped, escaped rendering and the run-hint clause is gated on the row COUNT the emitter reports, so the seams that carry those two facts changed shape together and every gating row is that one change. api-surface writeFlipHeader 4->5: ONE parameter, the count of test files the caller already rendered, so the header can gate its clause on the rows the document will carry - a flip with <tests n=0> paid 180 B for a rule about rows it has none of, and the header cannot see the corpus to count them itself (one caller, updated in the same commit). duplication/new-clone renderToString | chargeSection: chargeSection is the est_tokens family's FAULT-INJECTABLE buffer (openChargeBuffer is constexpr-false in release and is what estchargecheck degrade arm switches on), so it cannot route through a plain open_memstream seam without deleting the only reachable degrade path the gate has; mcpverbs captureXml WAS folded into the seam in this same commit rather than acked. short-horizon-churn churn=self on writeFlip/writeFlipHeader/writeHandoffPacket/writePrContext/partitionTestRows/dispatchMcpLine is this lane own footprint across the two rounds of one item - the E1 landing, the CI budget fix, the first review round and this one - none foreign, none thrash. | prior: E1/A4-2: every tests_to_run emitter re-routed through testmap.h's one seam (testRowsRendered) so runner-less rows group by evidence; the 12 sites were rewritten in-window by M21(b) and F1, and touching that family once more is the item itself

Subject: [PATCH 72/87] fix(skillsinstall): dedupe FdGuard into
 rw::pathguard::OwnedFd, RAII-guard the popen handle (review items 1, 2,
 optional)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

FdGuard was a byte-for-byte duplicate of rw::pathguard::OwnedFd (both
already flagged by --quality-delta's duplication detector and acked as a
coincidental token-shape collision in an earlier round). Its two call
sites (writeStoreFile, storeContentsMatch) only ever use the local `fd`
int directly, never the guard's own member, so swapping the type is a
pure rename — no crashsweepcheck.sh S2 registry change needed, since S2's
OWNERS pattern only recognises an open() call handed straight to an
owner's constructor in the same expression, not this file's
open-then-wrap-separately shape either way.

runShellCapture's popen() was closed by a single unconditional pclose()
at the end of the function with no early return between them today — safe
by construction, but only for as long as nobody adds one. PopenGuard
mirrors OwnedFd's shape (move-only, RAII) but closes via pclose(), never
rw::OwnedFile's fclose() — using OwnedFile here would call the wrong
close function for a forked child's stream. closeAndStatus() hands back
pclose()'s raw status for the WIFEXITED/WEXITSTATUS decode the same way
the destructor-only path could not.

Left the ~15 other raw popen/pclose call sites elsewhere in the codebase
(gitmine.h, quality.h, gitoracle.h, ...) untouched — introducing a new
RAII convention in this one file while the dominant established pattern
stays raw would be inconsistency, not a fix, and none of those sites was
in scope for this review round.

Verified: full pargates suite green on both build/ and a --clean-first
asan/ rebuild (crashsweepcheck's S2 registry unchanged and still
accounted-for), --quality-delta gating=0, deterministic, xmllint clean.

Subject: [PATCH 73/87] docs(changelog): add [Unreleased] entry for embedded
 skills/hooks + ripwire skills install (#225)

The review round on #293 correctly noted this repo keeps one
CHANGELOG.md, not changelog.d/ fragments, and #225's whole feature had
no entry yet. Added one in the file's own voice, summarizing the embed
step, ripwire skills install, --doctor's provenance reporting and the
mise/aqua shim fix, with the new gates it names.

Subject: [PATCH 74/87] docs(changelog): rewrite the [Unreleased] entry to
 cover the PR's full final state

The first pass under-covered the PR: missing --all/--force/--contributor,
link-safety repair/prune, store-integrity verification, atomic writes,
Hermes-native skills, the substitution-meter banner, and the usage-text
fixes, and buried wrap's shell-escaping fix inside the skills-install
paragraph instead of naming it as its own entry. Rewrote both to describe
the shipped feature as it stands now, not the sequence of commits that
got here, and split the wrap fix into its own ### Fixed entry since it
hardens an existing, previously-shipped command rather than being new
skills-install behavior.

Both new gates' ok() omitted the house `; return 0;` tail, so a failed
printf inside it (a full disk, a closed fd) would report the ARM as a
shell-level failure to a `cmd && ok ... || no ...` chain instead of
recording it through the fail= accumulator — gateexitcheck.sh's (G1)
check caught both.

hooksembedrecursivecheck.sh also called `git worktree add --detach
"$WT" HEAD` directly against the real repository — exactly the pattern
test/worktreeleakcheck.sh's (A) scan exists to forbid (a killed run
leaks a worktree registration into the shared .git that every other
session then has to clean up by hand). Switched to
ripwire_private_checkout (test/lib/headbinlib.sh), the one sanctioned
way a gate checks out a commit — a private `git clone --shared
--no-checkout` + `checkout --detach`, never a worktree in $ROOT/.git.
Also added a real `ripwire` binary run against the checkout right after
checking it out (best-effort, targeting $WT itself so it works whether
the checkout is the real ripwire tree or worktreeleakcheck's own tiny
fixture repo) — every other ripwire_private_checkout caller does this as
its actual functional check, and worktreeleakcheck's kill-timing tests
use exactly this invocation as their synchronization point for when to
deliver a signal; without it, a scenario "never reaches a checkout of
the commit" and proves nothing.

Subject: [PATCH 76/87] fix(test): close two false-greens binoverridecheck.sh
 found in the new gates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hooksembedrecursivecheck.sh ran its sanity ripwire invocation against
the checkout but discarded the exit status (`[ -x "$BIN" ] && "$BIN"
... >/dev/null 2>&1`), so it stayed green even with RIPWIRE_BIN pointed
at a binary that fails on every call — binoverridecheck.sh's (4) exists
specifically to catch this class. Now gates on the call: a missing
binary exits 2 (matching the house convention), a failing one reports
through no() and exits 1.

shimselfunverifiedcheck.sh was flagged the same way, but its actual
shape never executes $BIN at all — it only `cp`'s it as inert bytes
into a fixture mise install path (the managed-candidate side of a byte
comparison a different, non-empty-selfPath test would exercise, not
this one). Added it to binoverridecheck.sh's EXEMPT and
STATICALLY_UNREACHABLE sets with the same verified-by-reading rigor
every other row there carries, rather than fabricating a dependency on
the binary this gate was never meant to have.

Subject: [PATCH 77/87] chore(restack): reconcile gate count and printf-parity
 manifest with main's train
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

git-spice upstack restack replayed this branch onto main after two
integration trains landed (os.h seam refactor, GDScript language
support, cross-TU layout-drift detection — 18 commits, 652 files). Two
mechanical follow-ups, exactly as the maintainer's own review comment on
skillsinstallcheck/hooksembedrecursivecheck/shimselfunverifiedcheck/
doctorstalecheck from this branch, resolved commit-by-commit during the
rebase) pushed the count to 649 — regenerated via
docs/gatecount_build.py; --help's byte-identity pin moved again since
main's own trains changed --help text too — re-pinned with
UPDATE_GOLDEN_EXPECT=help_all, confirming only that one label moved.

Subject: [PATCH 78/87] chore(restack): reconcile gate count (651) and
 printf-parity manifest with main's second train
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A second `git-spice repo sync` pulled 130 more commits (another
integration train — clean-env.sh/statcompat.sh centralization, a
Win32-logic gate, os.h hardening). Same two mechanical follow-ups as the
first restack: gate-loop union pushed the count to 651, and --help's
byte-identity pin moved again — re-pinned with UPDATE_GOLDEN_EXPECT=
help_all, confirming only that one label moved.

Verified this restack does not regress main's own env/stat-compat work:
every conflict that touched clean-env.sh vs this branch's own
unset-agent-env-variables.sh was resolved toward clean-env.sh (a strict
superset), across 9 files. Nothing here shadows or duplicates
statcompat.sh within the same file.

Subject: [PATCH 79/87] fix(test): adopt main's clean-env.sh/statcompat.sh,
 retire this branch's own duplicates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This branch's own test/lib/unset-agent-env-variables.sh and two
hand-rolled GNU/BSD stat blocks (test/skillsinstallcheck.sh) were
independent, correct implementations of the exact fixes main's
integration trains centralized as test/lib/clean-env.sh and
test/lib/statcompat.sh. Migrated every remaining caller
(agenttablecheck.sh, doctorstalecheck.sh, hermesinstallcheck.sh —
which also had a genuinely redundant SECOND sourcing left over from
before clean-env.sh existed on this branch's own timeline,
selfcontainedcheck.sh, shimselfunverifiedcheck.sh, skillsinstallcheck.sh)
to the shared helpers and deleted the now-dead
unset-agent-env-variables.sh.

clean-env.sh's agent-home list was missing OPENCLAW_STATE_DIR, which
unset-agent-env-variables.sh carried as a "belt-and-braces" entry
(openclaw honours no such var today, per src/wrap.h's own comment, but
kept for when/if that changes). Rather than re-add a one-off unset in
agenttablecheck.sh (the only migrated file that tests openclaw), added
it to clean-env.sh itself — the right home for a var every agent-home
caller should clear — and updated test/gitenvhermeticcheck.sh's own
pinned variable-name list (arm C) to match, since that gate asserts
clean-env.sh's unset lines name exactly that set.

skillsinstallcheck.sh's two hand-rolled stat blocks are now
statcompat.sh's mtime_of/mode_of, identical implementations, one
sourced definition.

Subject: [PATCH 80/87] fix(os): close os::symlink's POSIX/Windows declaration
 parity gap; fix a duplicate-key ack entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This branch's own commit that added os::symlink (routing skillsinstall.h's
raw ::symlink through the os.h seam) predates main's later Windows-hardening
train, which added test/osswitchcheck.sh's arm (E): every function os.h
declares on the POSIX side must have a matching declaration on the Windows
side. symlink never got one, so the restack surfaced it as a real (E)
failure — not present at the time that commit was written, but real now
that the check exists.

Declared symlink alongside its neighbours in os.h's Windows
declarations-only block, and gave it a body in os_win32.cpp: ENOSYS/-1,
the same shape os.h's own exepath() fallback already uses for "not on
this platform." A full CreateSymbolicLinkW implementation needs
privilege/developer-mode detection this port hasn't built, and
skillsinstall.h's own header comment already documents this exact gap
as deferred — declared and honestly unavailable, not silently wrong,
and not guessed at without a Windows toolchain to verify against.

Separately, the mid-rebase resolution of a genuine same-(kind,key) ack
collision in .ripwire_quality_acks (kept both lines) left the ledger in
a shape the tool's own canonical form doesn't produce — caught by
test/qackconcurrencycheck.sh's (6)/(7): re-running the tool merged them
into one line ("| prior: ...") on a run that should have left the
ledger untouched. Applied that exact canonical merge by hand.

 ack verbosity 225d0a144176c808 115 cid=fdf6f7041c20fcbe OPTREMARKS F3 (docs/OPTREMARKS.md §8b): the ~430 per-AST-node std::strcmp( t, "literal" ) sites in the five ingest walk sections become rw::kindIs (src/infra/nodekind.h) — an inline compare, because strcmp is an external symbol LTO cannot inline and on macOS costs two dyld stub hops before it starts. Measured: 10.6% of busy CPU in strcmp leaves on a cold llvm run, 6-12% on four other corpora; 0.23% after. Output byte-identical across 7 corpora x 5 verbs, argvdiffcheck 640/642 vectors identical (the 2 that differ are the +dirty build stamp in --version). WHAT THESE ROWS ARE. (a) 95 short-horizon-churn rows, churn=self: the mechanical rewrite touches essentially every function in ingest_{metrics,binds,sidecap,relations,names}.h, so every one of them shows this lane's own single edit. Not thrash — one commit. (b) 7 duplication rows and 1 new-clone-of-reused-helper. These are REAL new clone groups (--clones, uncapped: 407 groups before, 409 after; the rewrite adds 7 and removes 5) and they are IDIOM COLLISIONS, not copies. kindIs( t, "x" ) is shorter than std::strcmp( t, "x" ) == 0, so short predicate bodies that were previously above the clone threshold now match each other's normalized token stream. Six of the seven pair a node-kind || -chain with an unrelated || -chain over a DISJOINT literal set in a different subsystem — cc_isParamList (tree-sitter parameter-list kinds) against predicatePrefixed (English name prefixes is/has/can), against sliceIsJsPatternKind (JS destructuring kinds), rubyCallIsAssignmentTarget against slice.h's JS binding probes. The tool's own rule is that two ladders over the SAME enum are a copy; these share no non-keyword identifier and no domain, and merging any pair would need a helper parameterised on an unrelated literal table — a wrong abstraction to satisfy a lint. The seventh, kindIs | lexTokenEqualsLowered, is the same shape at 56 tokens with materially different contracts: lexTokenEqualsLowered takes an explicit length and case-folds one side, kindIs takes its length from the literal's type and compares the terminating NUL as an ordinary byte — and that NUL comparison is precisely the safety property kindIs depends on (test/nodekindcheck.sh arm B proves the absence of a read past it with an mprotect(PROT_NONE) guard page). Folding them together would erase the one property being gated. Gate: test/nodekindcheck.sh, 4 arms, 1,348,096 enumerated (candidate, literal) pairs against std::strcmp plus two mutation controls that each turn an arm red.

Subject: [PATCH 81/87] fix(skillsinstall): convert std::filesystem::path to
 narrow string before every os:: call
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI's windows (cl, ninja) and windows (clang-cl, ninja) legs both failed:
6 call sites (renameAtomic, symlinkOrRefuse, writeStoreFile,
storeContentsMatch x2, pruneStale) passed a std::filesystem::path's own
.c_str() straight to os::rename/symlink/open/lstat/unlink, all declared
const char*. On Windows, std::filesystem::path::value_type is wchar_t,
so path.c_str() is const wchar_t* — a real type mismatch, not a warning,
and cl/clang-cl both refused to compile it.

This is the same defect for all 6, and it never surfaced before because
os::symlink had no Windows declaration at all until the parity fix
earlier in this branch — the file was never actually type-checked for
Windows until that declaration existed to type-check against.

Every other os::-calling site in the tree already converts through
.string().c_str() first (src/pathguard.h's isSymlink/commit take
std::string precisely so callers do this once at the boundary;
src/editpreview.h and src/main.cpp already use this exact spelling).
skillsinstall.h's own os:: call sites now match: from.string().c_str()
instead of from.c_str(), at all 6 flagged sites. The 3 remaining
.c_str() calls in this file (runShellCapture's cmd, resolveJqPath's
candidate, runCommandCapture's cmd) are already std::string, not
std::filesystem::path — verified by reading each declaration, not
guessed at.

Not compile-verified locally (no Windows toolchain in this environment)
— matched against both CI legs' full error output, which name exactly
these 6 sites and no others, so the fix set should be complete.

 embedded-skills installer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three spots in INSTALL.md still described the prebuilt/curl installer
(scripts/install.sh) as staging skills/hooks on disk. Since the embedded-
skills work landed, that installer activates them straight out of the
binary's own embedded store — nothing staged. Only the source-build
./install.sh route (lines 70-75, left untouched) still genuinely stages
skills/ and hooks/ under <prefix>/share/ripwire/.

Subject: [PATCH 83/87] fix(skillsinstall): close a misdirected-subcommand gap
 and two CWEs from review
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- main.cpp: `ripwire skills instal` (argc==3) fell through the old
  argc==2-only bare-subcommand guard and reached parseArgs, which took
  "skills" and "instal" as two crawl roots — silently mapping skills/ as
  a repo instead of naming the misspelling. Widened the guard to any
  argv[1]=="skills" with an unrecognized argv[2]. Arm 22 in
  skillsinstallcheck.sh proves it red-then-green.

- resolveJqPath: only an absolute PATH entry is now considered. An empty
  or relative entry used to resolve to the current directory (matching
  sh's own PATH semantics, same as os::which/resolveExecutable) — correct
  for "what would a shell run", wrong here, since the result is spliced
  into a shell command string that `--hook` can run inside an untrusted
  repository (CWE-426). Arm (H) in skillinstallcheck.sh plants a jq in an
  empty/relative PATH entry and proves it never runs.

- writeManifestV2 / runJqMergeFile: a temp-then-rename over an existing
  manifest or hook config no longer silently loosens its mode to
  0666 & ~umask. Both now `os::stat` the original first and `os::fchmod`
  the temp file to its exact bits before the atomic commit, same idiom as
  mcpedit.h::atomicWrite (CWE-732). A first-ever file keeps the umask
  default. Arm 23 in skillsinstallcheck.sh and arm (I) in
  skillinstallcheck.sh cover the manifest and the settings.json paths.

- skillsinstallcheck.sh arm 4: the prune assertion checked `-e` on a
  symlink whose target is intentionally dangling, which always follows to
  false — vacuous. Fixed to `-L`.

Subject: [PATCH 84/87] test(hermes): assert a planted ripwire-prefixed user
 file survives install
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Hermes install test planted a user file named ripwire-repo-map-notes
to prove the installer's prune step only removes symlinks it owns, not
real files that merely share the ripwire- prefix, but never asserted the
file was still there afterwards — the scenario ran and proved nothing.

CodeRabbit review, PR #293.

Subject: [PATCH 85/87] fix(skillsinstall): never trust a symlink or regular
 file planted at the store key
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

extractGroup's "already extracted, trust it" check only cleared storeRoot when
lstat reported a real directory. A symlink or a regular file at that name fell
through untouched: rename(tmp, storeRoot) then failed ENOTDIR, and the fallback
std::filesystem::exists() followed a symlink (or reported the file present)
and returned ok anyway — a planted symlink's target text, or a truncated file,
got served as the store.

Fixed both ends: any pre-existing non-real-directory at the key is cleared
(std::filesystem::remove_all removes a symlink or a plain file as itself, same
as POSIX remove, never following it) before extraction, and the post-rename
race-fallback re-verifies with the same lstat + storeContentsMatch pair the top
of the function uses, never exists()/is_directory() — both would follow a
symlink a racing writer, or an attacker, could plant at the name instead.

Reproduced and reviewed against a build of 436590f9 by @joyful-ii-V-I (both the
symlink and the regular-file case), review round on PR #293. test/skillsinstallcheck.sh
arms 24-25 pin both, red-first against the unfixed extractGroup.

Subject: [PATCH 86/87] fix(skillsinstall): find ripwire beside skills/ in a
 release archive, copy-fallback where symlinks aren't supported
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two gaps in the thin skills/install.sh wrapper on a real release layout, both
flagged in review round on PR #293 (item 3):

- find_ripwire only checked build/ripwire, build-release/ripwire and PATH. A
  release tarball or the Windows zip ships ripwire(.exe) at the archive root,
  beside skills/install.sh itself — `bash skills/install.sh` from an unpacked
  archive failed with "no built or installed ripwire binary found". The archive
  root is checked first now, exactly as unambiguous as a checkout build.

- os::symlink is ENOSYS on Windows without Developer Mode/SeCreateSymbolicLinkPrivilege,
  so every skill link failed outright. linkOrRefuse now falls back to copying
  the store file's bytes on ENOSYS — the store is content-addressed and
  immutable, so a copy is exactly as correct as a link, it just doesn't follow
  a later store update on its own. regularFileContentsMatch lets a later
  install run recognise that copy as already correct (installForAgent's
  pre-check otherwise treats any regular file at the destination as foreign
  content it refuses to touch). README's Windows section now documents the
  fallback instead of a manual PowerShell copy-by-hand workaround.

test/skillinstallcheck.sh arm (J) pins the archive-root probe, red-first
against the old find_ripwire.

Subject: [PATCH 87/87] chore(quality): re-ack the stale duplication finding,
 reconcile printf-parity manifest
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two ledger-only fixes from the review round on PR #293:

- item 2: `duplication extentsuspect.h::inSet | skillsinstall.h::symlinkOrRefuse`
  grew from 30 to 32 tokens (an unrelated upstream change to one of the two
  one-line wrappers this ack already covers), so the existing ack no longer
  matched and --quality-delta gated. Re-acked with the emitted count; the
  finding itself is unchanged — still a coincidental token-shape collision
  between two unrelated one-line wrappers, not real duplication.

- extractGroup's own short-horizon-churn from this round's store-key-trust fix
  (previous commit) acked with its rationale, consistent with every other
  review-response round this branch has acked the same way.

- test/printf_parity.manifest's help/help_all rows regenerated after main's
  latest pull (155 commits, including a --readability help-text rewrite);
  impact/clones/help/pack_signatures also moved because those verbs analyze
  this repository's own source, which main's pull changed underneath them.

WAVE-3 VERIFIER CORRECTION (P6-6): this reason previously named writeHealthRows as a third member, which is in NO clone group at all - that made the ack unverifiable against the ledger and made '2-instance' read as a three-way judgement it never was; and it cited 'the DOD doctrine' (G2), a DATA-LAYOUT guardrail that says nothing about a six-line emitter running once per report. The engineering call is unchanged and was independently attacked and NOT refuted. Its real authority is --quality-delta's own 'a wrong abstraction beats a low score' plus this repo's own fold threshold: src/mergescout.h:637 writeSymRows and src/main.cpp:8746 writeDropRows were folded because the attribute SCHEMA is identical and only the tag varies, while writeOversizeRows/writeDropRows sit deliberately UNFOLDED in the same block at a LARGER similarity=0.90 tokens=139, for exactly the discriminator that applies here - differing attribute sets. writeLangRows/writeUnindexedExtRows differ in the key attribute name (x= vs n=), the key SOURCE (a stored field ue.ext vs a derived rw::langTag) and the attribute arity (files= vs files=+symbols=), so they fall on the repo's own keep-separate side; every consolidation sketch is net longer, needs two callables per site, and drags the fixed-buffer snprintf into a lambda past test/fixedbufsweep.sh:259's per-site census (which this wave already had to re-pin 191->193). TREND, recorded rather than left silent: this six-emitter block now carries TWO unfolded clone pairs (139 preexisting + 89 new) and accretes sibling emitters by design. At a THIRD same-schema sibling, writeSymRows' three-caller precedent flips the answer - and it cannot creep there silently, because this ack is keyed at exactly tokens=89 over exactly these two members, so a third member is a new member set, a new group, and a new finding

Every MCP gate in this suite is deliberately STANDALONE — the house rule in their own headers is 'does NOT edit regression.sh or any other existing test file', so a gate carries its own 3-4 line JSON-RPC transport wrapper (mcp_call in mcphandlecheck, mcpCall in mcpeditpresencecheck, the curl wrapper in mcpremotecheck). test/mcptoolprunecheck.sh needs BOTH transports (HTTP for the pinned-root arms A-E/G, stdio for arm F, and the pair is the point: pinning is exactly what makes the omission provable), so its http_call and stdio_call land as the 9th and 10th members of two families that already exist. Extracting a shared test/lib harness would couple every MCP gate to one file and is a suite-wide refactor, not this lane's; sharing one of the two existing spellings instead would make this gate fail whenever an unrelated gate edits its own helper.

Two cheaper spellings were tried and REJECTED by measurement first: a hand-rolled scan loop is the five-instance clone shape ingest.h::isNonTextExtension's note already names, and a std::find one-liner cloned KindCounts::total alone.

The tool's own rule is that two ladders over the SAME enum are a copy; these share no non-keyword identifier and no domain, and merging any pair would need a helper parameterised on an unrelated literal table — a wrong abstraction to satisfy a lint. The seventh, kindIs | lexTokenEqualsLowered, is the same shape at 56 tokens with materially different contracts: lexTokenEqualsLowered takes an explicit length and case-folds one side, kindIs takes its length from the literal's type and compares the terminating NUL as an ordinary byte — and that NUL comparison is precisely the safety property kindIs depends on (test/nodekindcheck.sh arm B proves the absence of a read past it with an mprotect(PROT_NONE) guard page). Folding them together would erase the one property being gated. Gate: test/nodekindcheck.sh, 4 arms, 1,348,096 enumerated (candidate, literal) pairs against std::strcmp plus two mutation controls that each turn an arm red.
 ack short-horizon-churn a7f08eff37098826 16 cid=6474f6e80ffb0f2c skills-install fix (redhat-et/ripwire#293): the two gating short-horizon-churn rows on installForAgent and pruneStale are this same commit's own edits (directory-scan prune, hermes-native skill collection extracted to collectCurrentSkills) — no foreign code rides with them.

The complexity/verbosity growth in the assembler is the partition-preserving row loop (the window advances on UNFLAGGED rows only, so a flagged row and its sites_l= ride every page uncut) plus the in-band legend that says what pages and what never does; the churn rows are this lane's own footprint across cli.h/mcp*/editcheck*, none foreign.
