should_build_okf heuristic is undocumented in cfs retrieve --help
Severity: Minor
Problem
cmd_retrieve's argparse description and --expected-future-queries help text were not updated to mention should_build_okf/tier2_escalations or the break-even heuristic now driving an automatic recommendation, unlike this project's own pattern of documenting comparable heuristics (--margin-threshold, section-level inference) directly in --help.
How to reproduce
Run cfs retrieve --help.
Expected behavior
The help text gives at least a one-sentence hint that Tier-2 escalations are now tracked automatically per document and can trigger a should_build_okf recommendation.
Actual behavior
No mention of should_build_okf, tier2_escalations, or the break-even logic anywhere in --help output.
Impact
Reduces discoverability of a feature specifically meant to reduce reliance on human judgment calls — an operator has to read the source to learn it exists.
Suggested correction
Extend cmd_retrieve's description (or --expected-future-queries's help string) with a short note about the automatic, usage-based signal.
How to verify
Re-run cfs retrieve --help and confirm the new fields/heuristic are mentioned.

Fixed in 9595f06: extended cmd_retrieve's description and the --expected-future-queries help text to explain that tier2.should_build_okf is now computed automatically from real recorded Tier-2 escalations, and that the flag is optional (used only for reasoning about a hypothetical future volume instead).

…ts silent races Review findings on PR constructorfabric#136 (ainetx): - Major: get_or_build_doc_index's cache-miss build+save path took no lock, while record_tier2_escalation's read-modify-write did (both against the same doc_index.json). An unlocked structural rebuild (triggered by cascade.route_tier1's own find_sections/score_sections calls) could read a stale snapshot of the counter and overwrite a newer, real escalation count back down -- silently reverting recorded usage. Live-reproduced and fixed by moving tier2_escalations out of the structural cache entirely, into its own small counter file with its own lock (_escalation_cache_path/get_tier2_escalations/record_tier2_escalation): nothing else ever touches or locks that file, so there is nothing left to race. - Minor (same redesign): the old design also rewrote the *entire* structural index (all sections, summaries) on every single Tier-2 query just to increment one integer, contradicting doc_index's own "read once per file" goal. The new counter file is a tiny, independent write -- O(1) regardless of how large a document's cached payload is. - Major: commands/doc_index.py (cfs doc-index) never surfaced tier2_escalations at all, even though get_or_build_doc_index carried it -- same bug class as PR constructorfabric#109's retrieval_sections omission, which this project already has a named regression test for. Added the field to both JSON and human output, plus an analogous regression test. - Minor: record_tier2_escalation discarded save_doc_index's return value and always reported a fabricated success count. The rewritten version catches a real write failure (atomic_write_text raising) and returns None instead, matching annotate_section_summary's existing contract. - Minor: should_build_okf was undocumented in `cfs retrieve --help` and had no documented caller action anywhere in the codebase. Extended the CLI help text and _baseline_recommendation's docstring with the expected caller action (summarize each retrieval_section, then call okf.write_concept_file per section -- the same enrichment pass OKF bundles are always built by). - The "no regression test for a cache predating tier2_escalations" finding is moot under the new design (the field was never part of the structural cache's schema to begin with) -- covered instead by a new test asserting the structural index never carries the field at all, plus a concurrency test that hammers get_or_build_doc_index rebuilds against record_tier2_escalation calls and asserts no increment is ever lost (the Major race's actual regression test).

…or the escalation sidecar file Second ainetx review pass on constructorfabric#136, against the 9595f06 sidecar-file redesign: - Major: record_tier2_escalation was called unconditionally on every route_tier2 invocation, with no way to tell a fresh Tier-2 escalation apart from a caller re-invoking route_tier2/route_query for the same logical query after a transient failure or timeout -- silently double-counting on retry. Adds an optional `escalation_key` idempotency token: record_tier2_escalation persists a bounded window of recently-seen keys (`_MAX_RECENT_ESCALATION_KEYS`) alongside the count, under the same lock as the increment itself, and a key already seen returns the current count unchanged instead of incrementing again. No key (every existing caller's current behaviour) preserves the original always-increment contract -- there's nothing to deduplicate a bare call against without one. cascade.py's half of this wiring is in the next commit. - The counter file had no schema/version field for future format evolution, unlike the structural doc-index cache's deliberate `schema_version`/`path`/`etag`. Adds `_ESCALATION_SCHEMA_VERSION` to the written JSON; get_tier2_escalations degrades gracefully (no crash, no spurious warning) on a file predating the field, since this is a brand new, unreleased counter with no real pre-existing unversioned file to migrate from. - get_tier2_escalations didn't reject a negative persisted count (e.g. a hand-edited or truncated-write `{"tier2_escalations": -5}`), which record_tier2_escalation's `+ 1` would otherwise propagate forward indefinitely. Clamped to 0, the same fallback every other corrupt-data case in this function already uses. - get_tier2_escalations returning 0 for both "never escalated" and "corrupt/unreadable" was, and remains, ambiguous to a caller -- not changing that return-type contract (accepted, documented limitation), but the underlying logger.warning calls now use distinct wording per failure mode (missing Studio project, corrupt/unreadable file, wrong JSON shape, write failure) so a log reader can at least tell them apart.

…/CLI; guard the break-even constant's sign; document the outside-project caveat Rest of the second ainetx review pass on constructorfabric#136 (see the prior commit for the sidecar-file half of the double-count fix): - Threads the previous commit's `escalation_key` through route_tier2 -> route_query -> a new `cfs retrieve --escalation-key` CLI flag, so a real caller can actually use it: pass the same key again when retrying the same logical query (a timeout, a transient failure) and the retry doesn't inflate tier2_escalations a second time. Added regression tests at all three layers (route_tier2, route_query, and the CLI) that simulate exactly that retry and assert the counter only advances once, while a genuinely new key still counts. - `_TIER2_BREAK_EVEN_ESCALATIONS = math.ceil(_OKF_BUILD_COST_TOKENS / (_BASELINE_PER_QUERY_TOKENS - _OKF_PER_QUERY_TOKENS))` is computed once at import time and only makes sense while baseline costs strictly more per query than OKF -- true for the three hardcoded rates today, but nothing enforced that invariant on a future edit to them. Adds an import-time assertion that fails loudly instead of silently producing a nonsensical break-even point (or raising a division-by-zero deep inside math.ceil with no context). Also adds a direct test pinning `_TIER2_BREAK_EVEN_ESCALATIONS == 2`, since the existing tests only ever asserted the behavioral consequence (should_build_okf False at 1, True at 2), never the constant's actual value. - `cfs retrieve --help` documented should_build_okf as turning on automatically "regardless of whether [--expected-future-queries] is passed", with no mention that outside a Studio project (no resolvable cache dir) tier2_escalations can never be persisted at all, so the flag is always false there -- already covered by test_should_build_okf_is_false_outside_a_studio_project, just never surfaced in the CLI's own help text. Added the caveat. - No test drove cmd_retrieve to an actual baseline Tier-2 recommendation and checked the JSON output -- every existing JSON-output test only ever hit the resolved (Tier 1) tier. Added one that escalates twice and asserts tier2_escalations/should_build_okf are both present and correct in the machine-readable output.

…ile helper functions Fixes the "Validate Artifacts" CI failure on PR constructorfabric#136 (2 code-inst-orphan errors): commit 839afe8 added @cpt-begin/@cpt-end markers for two new helper functions (_load_escalation_file, _escalation_count_from) but never added their matching CDSL steps in this spec, so the traceability validator's spec-coverage check correctly flagged both as orphaned code markers. Added both as Supporting entries under the Document Index component, and updated items 9/10's own descriptions to mention the escalation_key idempotency mechanism, schema_version, and negative-count clamping those two commits introduced (previously undocumented here even though the code markers on get_tier2_escalations/record_tier2_escalation themselves weren't renamed, so they hadn't been flagged as orphans). Verified locally: `python3 skills/studio/scripts/studio.py validate` now reports 0 errors (was 2), 269 warnings (unchanged, pre-existing toc-* findings unrelated to this PR).

…escalations before break-even in human output Two new findings against the round-4 lock-timeout fix (constructorfabric#136): - Major (coderabbitai): with_file_lock creates the lock directory and opens the lock file *before* it ever attempts to acquire the lock -- an OSError from either of those (a permissions problem, a full disk, a missing parent on a broken mount) is not a TimeoutError, so the round-4 fix's specific `except TimeoutError` clause alone let it propagate straight through route_tier2 and crash `cfs retrieve` outright. record_tier2_escalation now also catches a bare OSError there, logging its own distinctly-worded warning ("could not be acquired") and degrading to the same None "could not persist" contract as the other three failure modes it already handles. Regression test monkeypatches with_file_lock itself to raise OSError and asserts None comes back with a warning logged, instead of the exception propagating. - Minor (ainetx): _human_retrieve only rendered tier2_escalations inside the should_build_okf branch, even though the JSON output already reports the field unconditionally as soon as it's known -- hiding real, already- recorded information from the human-readable view before break-even. Now renders the count whenever it's non-null, keeping the "would pay for itself" message conditional on should_build_okf specifically. Test drives cmd_retrieve in human mode (flipping set_json_mode off, then restoring it) for a single below-break-even escalation and asserts the count line appears without the payback message.

…l, not any OSError Major finding against the round-4 lock-timeout fix (constructorfabric#136): with_file_lock's bounded-timeout poll loop caught any OSError from flock(LOCK_EX | LOCK_NB), not just the errno flock actually raises for "someone else holds this lock right now" (EAGAIN, aliased EWOULDBLOCK on most platforms). A real filesystem/descriptor failure (EINVAL: not a lockable descriptor, EBADF: bad fd, ENOLCK: no lock resources on this filesystem type) would be silently retried for the full timeout and then reported as a generic "timed out waiting for the lock", discarding the actual errno that would have explained the real problem. Now only EAGAIN/EWOULDBLOCK is treated as ordinary contention and retried; any other OSError propagates immediately (chained via `from exc` where it still ends up wrapped as a TimeoutError on the contention path, unchanged there). Two new tests: one mocks flock to always raise EINVAL and asserts it propagates on the very first call, not after polling for the timeout; the other mocks flock to raise EAGAIN exactly twice before succeeding, proving the retry path still works for genuine contention.

… gate The "Spec Coverage" CI check started failing on this branch after the round-4 fixes (0e28ef3, 4acc23f, 487648c): granularity dropped to 0.4594 (main sits at 0.4606) because those commits added substantial new logic either with no @cpt-begin/@cpt-end marker at all, or folded into an already-large existing block -- both dilute the covered-instruction-density metric (granularity = actual_blocks / (effective_lines / 10), weighted by effective_lines across the system). Extracted four previously-unmarked or over-large pieces into their own properly-scoped, separately-marked functions, each with a matching new CDSL step in traceability-validation.md (same pattern as the earlier `code-inst-orphan` fix on this branch): - utils/cascade.py: the break-even constant's import-time invariant guard (assert + derivation) was bare module-level code with no marker at all. - commands/cascade.py: _escalation_key_arg (this branch's own addition) had no marker at all. - utils/atomic_io.py: the bounded-timeout poll loop was folded into with_file_lock's single existing inst-atomic-lock block; extracted into its own _acquire_lock_bounded, called from with_file_lock unchanged. - utils/doc_index.py: the escalation_key normalization logic (empty -> None, oversized -> None-with-warning) was inline inside record_tier2_escalation's already-large block; extracted into its own _normalize_escalation_key. None of these change behavior -- pure extraction/marking, verified by running the full affected test suite (171 passed, same count as before) and the full suite (5496 passed, 1 pre-existing/unrelated failure in test_eval_semantic.py, matching every prior commit on this branch). Verified: `cfs spec-coverage --min-granularity 0.46` now passes at 0.4601 (was 0.4594); `cfs validate` still reports 0 errors (no new code-inst-orphan findings from the new markers).

…g annotation get_or_build_doc_index's cache-miss/force-rebuild path called build_doc_index()+save_doc_index() with no lock at all, while annotate_section_summary's read-modify-write cycle already locks on the same cache path. A rebuild could build a fresh, pre-annotation snapshot while a concurrent annotate_section_summary call locked, loaded the old cache, added a summary, saved, and unlocked -- then the rebuild's own unlocked save would silently overwrite the file with its stale snapshot, discarding the summary with no error to anyone (constructorfabric#136, round-5 review, Major). Wraps only the rebuild-and-save call site in the same per-file lock annotate_section_summary already uses (with_file_lock on <cache_path>.lock), leaving save_doc_index itself lock-free so annotate_section_summary's own inner closure (which already calls save_doc_index directly while holding that same lock) doesn't try to re-acquire a lock it's already holding. When not force_rebuild, the locked path also re-checks cache freshness once more after acquiring the lock, so a rebuild that loses the race to a concurrent write returns that fresh (possibly already-annotated) cache instead of redundantly rebuilding a from-scratch, summary-less snapshot over it. Adds a deterministic regression test that forces the exact interleaving (intercepting get_or_build_doc_index's own pre-lock cache check to run a real concurrent build-and-annotate cycle first) and asserts the summary survives.

- cascade.py cmd_retrieve's help text now also names the lock-timeout

- doc_index.py's _human_doc_index now renders the escalation-count line
whenever the value is not None, so a genuine 0 ("never escalated")
still shows instead of being silently skipped by the old truthy
check.
- atomic_io.py's _acquire_lock_bounded docstring now notes its errno
check is scoped to POSIX flock(2) semantics only.
- test_cascade.py: test_escalation_key_rejects_an_oversized_value now
uses a real tmp_path file and asserts the error message names
--escalation-key specifically, instead of a literal "doc.md" that was
never created (so rc==2/ERROR couldn't tell "key rejected" from
"file not found").
- test_cascade.py: the 4 bundle_dir truthy-only assertions in
TestRouteTier2 now assert the exact expected path via
studio.utils.okf._okf_bundle_dir.
- test_cascade.py: adds an end-to-end TestCmdRetrieve test holding the
escalation lock externally, asserting cmd_retrieve degrades
gracefully (tier2_escalations/should_build_okf null/False, and the
escalation-count substep correctly omitted in human mode) instead of
hanging or crashing.
- test_doc_index.py: renames/updates the never-escalated human-output
test to match the _human_doc_index fix above.

No direct unit test for _normalize_escalation_key boundary behavior
Severity: Minor
Problem
The test file's import list (tests/test_doc_index.py) only pulls in _escalation_cache_path, annotate_section_summary, build_doc_index, diff_stale_sections, get_or_build_doc_index, get_tier2_escalations, infer_section_level, load_doc_index, record_tier2_escalation, save_doc_index -- never _normalize_escalation_key. Tests test_empty_escalation_key_never_deduplicates_across_unrelated_calls and test_oversized_escalation_key_is_treated_as_no_key only exercise the helper indirectly via record_tier2_escalation with an oversized key (length+1), and no test uses a key at exactly _MAX_ESCALATION_KEY_LENGTH to confirm it passes through unchanged.
How to reproduce
- Introduce an off-by-one regression in _normalize_escalation_key's length comparison (e.g.
>=instead of>). 2. Run the existing test suite. 3. No test fails, because none calls the helper directly at the exact boundary length.
Expected behavior
A unit test directly calling _normalize_escalation_key with '', a string of length exactly _MAX_ESCALATION_KEY_LENGTH, and one of length+1, asserting None/None/original-string-unchanged respectively, plus a caplog assertion that only the oversized case warns.
Actual behavior
Only integration-style tests through record_tier2_escalation exist; the exact-boundary case and isolated warning-only-on-oversized assertion are untested.
record_tier2_escalation -> _normalize_escalation_key (untested boundary) -> silently wrong None/str decision -> no test catches regression
Impact
A regression in the length boundary or warning condition inside _normalize_escalation_key could ship undetected, since no test isolates that function's boundary behavior from the larger read-modify-write flow.
Suggested correction
Add a TestNormalizeEscalationKey class (or similar) importing _normalize_escalation_key directly and asserting behavior for '', length-cap, and length-cap+1 inputs, including caplog checks for the warning.
How to verify
Run the new test with a deliberately introduced off-by-one in the length check and confirm it fails, then confirm it passes with the correct implementation.

Fixed in f60620e: added TestNormalizeEscalationKey, calling the helper directly with "", a key at exactly _MAX_ESCALATION_KEY_LENGTH, and one at +1, asserting None/unchanged/None respectively, with caplog confirming only the oversized case logs a warning.

Now interpolates the real _TIER2_BREAK_EVEN_ESCALATIONS value (2) and names its derivation (measured OKF-build/OKF-per-query/baseline-per-query token costs), instead of leaving a CLI user to go read cascade.py's source to find the number. - _normalize_escalation_key was only ever exercised indirectly through record_tier2_escalation with a length+1 oversized key -- no test pinned the exact boundary (a key of exactly _MAX_ESCALATION_KEY_LENGTH must pass through unchanged) or isolated the warning-only-on-oversized behavior from the larger read-modify-write flow. Added TestNormalizeEscalationKey, calling the helper directly with an empty string, a boundary-length key, and a boundary+1 key, asserting the correct None/unchanged/None results and that only the oversized case logs a warning.

Solid piece of work overall — the atomic-lock timeout handling, the standalone escalation counter kept deliberately separate from the structural cache, and the break-even math with its import-time invariant guard are all carefully reasoned and well-documented. Nothing here rises to blocking. A few minor notes worth a glance before or shortly after merge:
- Cache validity can miss same-size edits on coarse-mtime filesystems — the doc-index etag relies only on
mtime_ns+ size, which can miss a same-size edit landing within one filesystem timestamp tick. (discussion) - Concurrency regression test doesn't enforce a real overlap — the new locking test starts threads and sleeps rather than establishing an actual scheduling barrier, so it could pass without truly exercising contention; the
join(timeout=5)also isn't followed by anis_alive()check. (discussion) make ci's excluded job doesn't exist — it filters outcode-ranker, but no job with that ID appears in.github/workflows/ci.yml, so the documented exclusion can't be verified against reality.- Competitor claims stated as durable facts — dated claims (e.g. Appian Composer's April 2026 launch, Microsoft Agent Framework GA in Q1 2026) aren't tied to a verification date or revalidation instruction despite the stated per-release-cycle revisit requirement. (discussion)
with_file_lock's no-fcntlfallback bypasses the timeout contract — on platforms withoutfcntl,fn()runs immediately and unlocked even when atimeoutwas passed, silently diverging from the documented bounded-wait/TimeoutErrorbehavior.- Cascade spec overstates escalation counting for idempotent retries — the docs say every call records one real Tier-1 escalation, but
record_tier2_escalationreturns the existing count unchanged when theescalation_keywas already seen. - No direct unit test for
_normalize_escalation_key's boundary — the helper isn't imported directly in the test file, and no test confirms a key at exactly_MAX_ESCALATION_KEY_LENGTHpasses through unchanged. (discussion)

An unlocked structural rebuild (triggered byroute_tier1's ownfind_sections/score_sectionscalls) could read a stale snapshot and overwrite a newer, real escalation count back down. Fix: movedtier2_escalationsout of the structural cache entirely into its own small counter file (doc_index._escalation_cache_path/get_tier2_escalations/record_tier2_escalation) — nothing else ever touches or locks that file, so there's nothing left to race. Added a concurrency test that hammersget_or_build_doc_indexrebuilds againstrecord_tier2_escalationcalls and asserts no increment is ever lost.cfs doc-indexsilently dropped the field. Same bug class as PR feat(doc-index): section-granularity inference, hashing, and caching fixes #109'sretrieval_sectionsomission (which this project already has a named regression test for). Fix:commands/doc_index.pynow fetchesget_tier2_escalations(path)and includes it in both JSON and human output, with a matching regression test.record_tier2_escalationdiscardedsave_doc_index's return value and always reported a fabricated success count. Fix: the rewritten version catches a real write failure and returnsNone, matchingannotate_section_summary's existing contract; added a test that forcesatomic_write_textto raise and assertsNone(not a fabricated count) comes back.should_build_okfundocumented in--help. Fix: extendedcfs retrieve's description and--expected-future-queries's help text to explain the automatic signal.should_build_okf: true. Fix: added the expected caller action to_baseline_recommendation's docstring (summarize eachretrieval_section, callokf.write_concept_fileper section — the same enrichment pass OKF bundles are always built by).no regression test for a cache predating tier2_escalationsfinding, are both moot under the sidecar-file redesign (the field was never part of the structural cache's schema at all now) — replaced with a test asserting the structural index never carries the field, and updated traceability entries describing the new design.pytest tests/test_cascade.py tests/test_doc_index.py tests/test_okf.py -qat 152 passed —test_okf.pywas never part of this PR's diff (that number was copy-pasted from fix(cascade,okf): resolve PR #111 round-3 CodeRabbit findings that missed main #135's write-up).
