Embed skills/hooks into the binary; unify activation as ripwire skills install (#225)

[s0undt3ch]

Summary

Implements #225: skills and hooks are now embedded into the ripwire binary at configure time (a generated, content-addressed header) instead of being staged as separate files a curl/source install had to copy around. Activation is now one command, ripwire skills install, which extracts the embedded set into a versioned, immutable-by-hash store and symlinks from there into each agent's discovery directory (Claude Code, Codex, Codex-legacy, Hermes, openclaw). --doctor reports install provenance (declared vs. live, manifest staleness against the binary's own embedded version) instead of ever calling a version-manager shim STALE by mtime.

This collapses two previously-separate mechanisms (skills/install.sh's checkout-symlink installer, and the curl installer's $prefix/share/ripwire/{skills,hooks} staging step) into one binary-owned path, per the design already reviewed and approved by the maintainers in the #225 discussion.

What changed

• Embedding: CMakeLists.txt globs skills/ and hooks/ at configure time into generated/embedded_skills.h (byte-identical across two configures, CONFIGURE_DEPENDS on both the glob and each file, gated by test/selfcontainedcheck.sh).
• ripwire skills install: extracts into $RIPWIRE_DATA_HOME/{skills,hooks}/<version>-<hash8>/ (O_CREAT|O_EXCL|O_NOFOLLOW, atomic rename into place, immutable by content hash — a killed run can never leave a directory that reads back as "already extracted"), then symlinks into the destination agent's skill directory. Refuses to write through or replace a planted symlink or real file/directory even under --force; a dangling or foreign-but-live symlink is repaired; a link-loop failure is now counted and reported, never silent.
• Codex --hook merge: ported skills/install.sh's pre-wrap/skills install has no discovery path for binaries installed via mise/aqua-registry (or any channel outside the curl installer's layout) #225 install_codex_hook — PreToolUse nudge + SessionStart primer + UserPromptSubmit router merged into ${CODEX_HOME:-~/.codex}/hooks.json in one jq call (Codex has one install channel, matched by exact command, unlike Claude's isScript basename match).
• Claude's --hook: now also registers the UserPromptSubmit prompt router (install_claude_route, previously never ported to the C++ path) and emits the substitution-meter disclosure banner.
• --hermes: now collects skills/hermes/ripwire-*/ (Hermes-native content, e.g. ripwire-repo-map) in addition to the flat ripwire-* set, which it previously linked exclusively.
• pruneStale: no longer limited to entries the previous manifest tracked — it also scans the destination directory directly for ripwire-* symlinks outside the current set (a stray or dangling one, left behind by a hand-removed skill or an older installer), while still refusing anything outside its ripwire-* scope of authority.
• Store integrity: extraction no longer trusts the store directory's name (a content-hash key) alone; a byte-for-byte compare against the embedded reference catches a planted symlink, a partial extraction a killed run left behind, or on-disk tampering, and re-extracts from scratch when it doesn't match.
• No /tmp fallback: an unset HOME is now refused everywhere instead of silently redirecting writes to /tmp; settings.json and the manifest are written via temp-file-plus-atomic-rename instead of truncate-in-place, so a crash mid-write can no longer leave either empty.
• --doctor: skills rows carry not_installed=, stale= (manifest source vs. the binary's own embedded version), and a repair hint that names what's actually blocking (an untracked entry, not a command that can't fix it). The top-level binary-path row and the agent-specific rows both recognise a mise/aqua shim by location and compare byte-for-byte instead of by mtime.
• wrap: the printed skills install recipe line is shell-escaped (rw::shSingleQuote) — a resolved binary path containing $(...) or a backtick is now inert when pasted, not executable.
• Docs (INSTALL.md, README.md) and the release/source installers (scripts/install.sh, install.sh) updated to match; the curl installer's separate $prefix/share/ripwire/skills staging step is gone, replaced by the same ripwire skills install --all call the source build uses.

Known, deliberately out of scope for this PR

• Windows is out of scope (blocked on the separate native port, feat(platform): native Windows support (MSVC ABI + Clang, zero external deps) #44).

Testing

Two full whole-branch adversarial review rounds (building the binary, running the full pargates suite, and driving hand-built fixtures against --doctor/skills install under hostile environments — foreign symlinks, corrupt JSON, symlinked settings files, no jq on PATH, ambient env-var leaks) found and closed 3 Critical + several dozen Important/Minor findings across both rounds, including: an unrepairable v1→v2 manifest upgrade path, a manifest that recorded intent instead of outcome, an unescaped shell-injection vector in the printed recipe, two gates that were writing into the operator's real Codex/Hermes config during CI-style test runs, and several assertions that had silently stopped testing anything after an earlier refactor changed the output they grep for.

Rebased onto current main for this PR; the rebase surfaced (and this PR fixes) 18 raw-POSIX-call sites and one throwing-iterator use that predated main's portability lane, caught by osswitchcheck.sh/hazardpatterncheck.sh once replayed against it.

The release matrix subsequently caught nine gates red across all 24 shards, tracing to several slices of #225's own plan left unfinished at that point (Codex --hook, Claude's route registration, Hermes-native skills, prune's dangling-symlink scan) — all fixed and covered by gates in this PR. A further maintainer review round added store-integrity verification, removed the /tmp fallback, made the manifest/settings writes atomic, tightened pruneStale to an ownership check, and split an over-complex codexdoctor.h function; a flaky idempotent-store test arm (comparing stat -f's GNU filesystem-info output instead of falling back to stat -c as intended) was also fixed.

Full gate suite (661 gates) passes except two known, pre-existing/environmental flakes unrelated to this diff (legendcoveragecheck.sh, red on unmodified main too; pargatescheck.sh's timing probe, which only fails under -j6 parallel load and passes standalone).

Walkthrough

Changes

The binary now embeds skills and hooks at configure time and provides ripwire skills install for extraction, linking, pruning, manifest handling, and hook registration. Installer scripts, wrap recipes, doctor checks, documentation, and regression gates now use the native command. Version-manager shim detection and content provenance checks were added.

[joyful-ii-V-I]

Thank you, @s0undt3ch — this has moved a lot since the last pass, and it moved in the right direction. The four
features skills/install.sh used to own — the Codex --hook merge (including the exact PreToolUse/SessionStart/
UserPromptSubmit timeouts and limits the old script used), the Claude UserPromptSubmit router, the opt-in
announcement/meter-disclosure banner, and Hermes-native skill linking — are all ported now and read like faithful
ports, not rewrites. Every raw POSIX call in skillsinstall.h now goes through rw::os, matching the seam
discipline the rest of the tree adopted. skillsinstallcheck (18 arms), wrapverbscheck and selfcontainedcheck
(including its skills+hooks embed cross-check) all pass clean in our own rebuild, and CI is green across all 32
jobs. The Ubuntu idempotent-store flake is fixed at the actual root cause — a stat -f/stat -c GNU-coreutils
trap, the same shape cachehashcheck.sh already documents — not papered over.

What's left is smaller than it was, and mostly concentrated in skillsinstall.h itself.

Needed before merge

1. Check the skill store's contents instead of trusting its name. extractGroup (skillsinstall.h:142) still
   reads if( std::filesystem::exists( storeRoot, ec ) ) { return { true, {} }; } — no check that storeRoot is a
   real directory (not a link, not a partial extraction) and no byte comparison against the embedded files.
   Fix: lstat the store root and require a real directory; byte-compare each embedded file against
   storeRoot/<relativePath> (opened O_NOFOLLOW, size + memcmp — no hashing needed, the bytes are already in
   the binary). On a mismatch, re-extract to a fresh temp dir and rename over, or refuse with a disclosed reason.
2. Don't fall back to /tmp when HOME is unset. homeDir() (skillsinstall.h:61) is still
   envOr( "HOME", "/tmp" ). Refuse with a clear message when neither HOME nor RIPWIRE_DATA_HOME is set;
   VALIDATE that RIPWIRE_DATA_HOME/CLAUDE_CONFIG_DIR/CODEX_HOME are absolute.
3. Write settings.json and the manifest atomically. skillsinstall.h has zero calls to
   rw::pathguard::createExclTempFile/randomTempSuffix — ingest_cache.h, quality.h, gitoracle.h and
   mcpedit.h all use that helper already; this file still truncates-then-writes.
4. Scope the symlink prune to our own links. pruneStale (skillsinstall.h:288) correctly requires
   S_ISLNK before unlinking, but doesn't readlink the target and require it under dataHome()/skills/ — a
   user's own unrelated symlink happening to be named ripwire-<something> is still fair game for deletion.
5. Remove .superpowers/sdd/embedded-skills-implementation-plan/fix-wave-2-report.md. Still in the tree.
6. --quality-delta should gate 0 (we ran ./build/ripwire . --quality-delta=origin/main..HEAD ourselves —
   rc=2, gating="6"):
   • codexdoctor.h::skillsCheck complexity 3→26 (bar 15) — still one function with the manifest-parity check,
     the staleness check and a 3-way outcome if/else if/else all inlined.
   • envOr is still byte-identical between codexdoctor.h:34 and skillsinstall.h — move one copy to a shared
     header.
   • a new duplication pairing appeared: notes.h::sortNotes / skillsinstall.h::symlinkOrRefuse. This is not
     the same pairing your existing ack covers (symlinkOrRefuse | extentsuspect.h::inSet) — that ack won't
     silence this one; it needs its own ack or its own fix.
   • installForAgent (complexity 46) and runSkillsInstall (complexity 59) are both still one function each,
     ~120-150 lines. Splitting the per-entry decision out of installForAgent, and the argv-parsing / --all
     loop out of runSkillsInstall, should bring both under the bar.
   • one more gating row showed up that doesn't look like yours: flipimpact.h::buildSiteLocator /
     notes.h::buildNoteIndex duplication — neither file is touched by this PR. We think this is baseline
     attribution noise from the two trains that landed since your branch point, not something to chase on your
     side; we'll sort it out at train time.
7. Self-checks, per CONTRIBUTING §3 "Self-check, don't throw." Still none in skillsinstall.h. Good spots:
   VALIDATE the manifest's version/skill= shape and the environment paths that must be absolute; EXPECTS
   non-empty bytes in writeStoreFile; ENSURES a non-empty name out of skillDirNameOf; DISCLOSE the silent
   degrade paths (a lost rename race, a skipped foreign entry, an ambiguous manager layout).

Worth doing

8. The --doctor mise/aqua resolvers still look for a layout that doesn't match real installs. We checked
   directly against your own wrapverbscheck.sh fixtures: resolveMiseLayout expects <version>/bin/ripwire,
   but the fixture builds installs/ripwire/<version>/<archive>/ripwire (no bin/); resolveAquaLayout expects
   pkgs/redhat-et/ripwire/<version>/..., but the fixture (and real aqua) nests under
   pkgs/github_release/github.com/redhat-et/ripwire/.... Both would report managed_unverified for every real
   install today.
9. Create store directories with explicit modes (0755) — every create_directories call in
   skillsinstall.h still relies on the umask.
10. jq's stderr is already passed through (in-flight, since popen only redirects stdout) — the code comment
    claiming it goes to /dev/null is stale and worth a one-line fix. The other half of the old ask still stands:
    jq is invoked as a bare "jq" token, resolved by the shell's PATH, never pinned to an absolute path.
11. Usage text: bare ripwire skills still maps the skills/ directory as a repo (exit 0, dumps the corpus
    map) instead of printing usage; skills install --help still returns rc 2 ("unknown flag --help"); --help
    still doesn't mention skills install, so docs/COMMANDS.md never regenerates it.
12. The "N skill(s) linked" summary should only print once the links are verified — this falls out of item 1.
13. selfcontainedcheck's new hooks/ cross-check is a good addition but isn't recursive (glob, not
    rglob) — a hooks/lib/x.sh would still slip past it unembedded and silent.

Small items (optional)

• FdGuard (skillsinstall.h) still duplicates rw::pathguard::OwnedFd.
• runShellCapture's popen still has no RAII holder.
• shimBinaryCheck still reports ok=1 when selfPath is empty (codexdoctor.h:211) — should say unverified.
• This repo doesn't use changelog.d/ fragments (that wasn't accurate in the last round) — it keeps one
  CHANGELOG.md. There's no [Unreleased] entry there yet for embedding skills/hooks into the binary; worth
  adding one in the PR's own voice, the way other entries in that file read.

What's next

We had to rebuild main twice since the last round (two integration trains landed), so a merge of current main
into this branch will now pick up conflicts in README.md, docs/EVALS.md, present/deck5_ripwire_build.js and
test/regression.sh — all four are mechanical (gate-count/doc bookkeeping that regenerates on every landing), not
real conflicts, and we're happy to help resolve them when this rides a train. Once the items above are closed and
CI + a fresh review are green, this lands through our normal integration-train process, not a direct merge. Thanks
again for sticking with this — it's a substantial contribution and it's in good shape. Happy to answer anything
here as you go.

[joyful-ii-V-I]

Status, so this is not waiting on us silently.

This is not a 0.6.2 blocker — 0.6.2 is cut on the graph-completeness, byte and Windows work — and it is high priority for 0.6.3. The refreshed review above still lists six items, the load-bearing ones being: verify the store's contents rather than trusting its name, atomic writes for settings.json and the manifest (the helper already exists in-tree), scoping the symlink prune to links we own, and self-checks in the ~1,000 new lines per CONTRIBUTING §3.

Two things changed underneath you while this sat, both worth a rebase rather than a surprise: the gate roster moved (several trains landed, including a new git-environment hermeticity gate and a centralised stat helper that your own PR #298 work seeded), and kParserVer is now 119.

No rush from our side, and nothing here is a criticism of the direction — the design is the one agreed in #225 and the parity ports read as faithful. Ping us when you push and we will re-review promptly.

[s0undt3ch]

Pushed — rebased onto current main (through train-15, kParserVer 119; picked up the MSVC cl.exe
seam and the osswitch arm H hardening along the way).

On the four load-bearing items from the last review round:

• Store contents verified, not trusted by name — storeContentsMatch() byte-compares every
  embedded file against the store copy before extraction is skipped as "already done"
  (src/skillsinstall.h:180).
• Atomic writes for settings.json and the manifest — both go through
  rw::pathguard::createExclTempFile/commit() (src/skillsinstall.h:386, :842).
• Symlink prune scoped to links we own — pruneTargetIsOurs() requires manifest-tracking or a
  target resolving under our own store root before unlinking an untracked name
  (src/skillsinstall.h:396).
• Self-checks per CONTRIBUTING §3 — VALIDATE/EXPECTS/ENSURES at the manifest-parse and
  environment-path boundaries.

Also folded in since: usage text for bare skills/skills install --help, the mise/aqua layout
fix so --doctor resolves a real install instead of reporting managed_unverified, 0755
directory creation regardless of umask, jq resolved via an actual PATH walk, shimBinaryCheck
no longer claiming a comparison it never ran, FdGuard/OwnedFd deduped, a RAII guard on the popen
handle, and a CHANGELOG entry. Full gate suite (651 gates) green modulo the same
pre-existing/environmental flakes noted before (the scan-skills legend-coverage gap, a couple of
timing-sensitive gates under parallel load).

Ready for re-review whenever you have a moment.

91-93: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Pin RIPWIRE_DATA_HOME for the skills install call.

skills install extracts its content-addressed store before it links anything, and it reads RIPWIRE_DATA_HOME to pick the store root. This invocation sets HOME, AGENTS_HOME, CODEX_HOME and HERMES_HOME, but not RIPWIRE_DATA_HOME. On a machine that exports RIPWIRE_DATA_HOME, this arm writes into the real store instead of $TMP/h-$name.

test/installer_isolation.py in this PR adds RIPWIRE_DATA_HOME to the sentinel set it enforces, so the leak surfaces as a failure in that gate rather than here. test/skillsinstallcheck.sh, test/selfcontainedcheck.sh and test/skillinstallcheck.sh each close the same hole; this gate is the remaining one.
