…c index Heading-based JIT retrieval needs headings that are unambiguous, evenly sized, and structurally sound, and needs to parse a document's structure once rather than on every query. toc.py gains four warning-only checks (duplicate headings, depth jumps, oversized sections, missing top-of-file description) and doc_index.py adds a cached, stat-invalidated structural index (`cfs doc-index`) with a hook for attaching per-section summaries. Fixes applied after CI and CodeRabbit review of the initial version: - The cache-validity fingerprint was path+byte_size+line_count, which can't distinguish a same-size content edit from no edit at all, and load_doc_index() read the whole file on every cache hit regardless -- defeating the "read once, not per query" point of the cache. Now uses Path.stat() (mtime_ns + size): cheaper (no read on a hit) and correctly catches same-size edits, since a write always advances mtime. - The Studio directory was resolved from the process's cwd, not the indexed file's own path -- could target the wrong project's cache. - Two silent except-and-return-None blocks (pylint's custom silent-exceptions rule) now log at debug level, following the existing decision_log.py convention. - The JIT-readiness checks were filtered through max_heading_level, whose CLI default is 3 -- hiding real issues in H4-H6 headings, exactly as seen against a real PDF-converted document during development. They now always parse every level, independent of the TOC-completeness cap. - The missing-description check accepted any frontmatter block, even one with no actual description field. - validate_toc() exceeded pylint's local-variable limit after the JIT-readiness wiring; extracted into _collect_jit_readiness_warnings. - Registered the doc-index algo and the two new toc-utils instructions in traceability-validation.md with real per-function tracing (was whole-file-scope only, tripping the granularity floor and two code-orphan-ref/code-inst-orphan validate errors). - Whitelisted annotate_section_summary in vulture_whitelist.py per this repo's existing "future caller, exercised by tests" convention. - Added tests for every fix above plus the doc_index CLI's human-output path (previously the one sub-90%-coverage file). See constructorfabric#104. Verified: full pytest suite (4800 passed; the 12 failures present with or without this change are macOS-local temp-dir path quirks and pre-existing test-order flakiness, none in the files touched here), pylint and vulture clean on the changed files, cfs validate 0 errors, spec-coverage thresholds met.

…aleness Neither of these existed before: doc_index.py indexed every heading at every level, with no notion of "one retrievable section", and its staleness check was whole-file only -- any edit anywhere invalidated the entire cached index, making a real per-section partial rebuild impossible regardless of how small the actual edit was. infer_section_level() picks which heading level represents one real section, using the level's *frequency* as the signal: a document's real recurring structure (its chapters) shows up as the level used most often, while an occasional heading at an anomalous level -- exactly what PDF-to-Markdown conversion produces, since it assigns levels by font-size heuristics, not semantic depth -- is rare precisely because it's noise, not structure. Levels used only once are excluded as candidates outright. This is a direct, verified fix for a real failure found earlier building this feature: a real PDF-converted document put all 8 of its actual chapters on H5 and a single stray subsection on H3; treating H3 as "the" section level (or any fixed level) turned the entire back half of the document into one fake 6,601-line "section". Re-run against that same document with this change: 12 correctly-sized real sections, not one. build_doc_index() now also computes retrieval_sections -- headings grouped at exactly the inferred level (off-level stray headings stay inside whichever section they geographically fall under, rather than splitting one apart), each with a SHA-256 hash of its own text. diff_stale_sections() compares a file's current content against its last cached build at this granularity and reports which sections actually changed, matched by position (not heading text -- duplicate titles are real, see toc-heading-duplicate) -- the piece needed for a future caller to re-summarize only what changed instead of the whole document. Registered the three new instructions in traceability-validation.md; whitelisted diff_stale_sections in vulture_whitelist.py alongside annotate_section_summary (same "future caller, exercised by tests" situation). New code is 100% covered; existing sections/annotate/etag behavior is untouched and still passing. See constructorfabric#104. Verified: pytest (test_doc_index.py + test_toc.py: 156 passed; full suite: 4815 passed, the same 12 pre-existing macOS-local/flaky failures as on main, none in the files touched here), pylint and vulture clean, cfs validate 0 errors, spec-coverage thresholds met, and infer_section_level re-run against the real PDF-converted document that originally exposed the bug.

…abric#109 - cmd_doc_index() built its output from the index but omitted retrieval_sections/section_level in both JSON and human output -- the new data constructorfabric#109 added was invisible through the CLI. Both are exposed now, and the human formatter lists retrieval sections the same way it already lists the finer-grained ones. - A write landing between read_text() and _compute_etag() in build_doc_index() could save headings parsed from the *old* content stamped with the *new* file's etag; load_doc_index() would then treat that stale index as valid until a later edit changed the etag again. _read_with_stable_etag() brackets the read with a stat snapshot on each side and retries on mismatch, so the saved etag is provably the one that matches what was actually parsed. - diff_stale_sections() reported changed/unchanged sections by heading text alone; two sections sharing a duplicate title (a real, already-flagged possibility -- see toc-heading-duplicate) couldn't be told apart. Each entry now carries line_start alongside the heading text, which is what a caller should actually use to address "this specific section" afterwards. - annotate_section_summary() updated only index["sections"], leaving the matching retrieval_sections entry at summary=None even on success -- a caller reading retrieval_sections (the more relevant list for a future per-section summarizer) couldn't see the annotation. Now updates both when both have an entry at line_start. - toc.py's _frontmatter_has_description() accepted `description: # TODO` and `description: ""` as satisfying the check, since `#` and `"` both match \S. Now parses the field's actual value and rejects comments and empty/whitespace-only quoted strings. Extracted _compute_fresh_retrieval_sections/_position_entry out of diff_stale_sections() to stay under pylint's local-variable limit after the line_start addition; registered the new instructions (stable-read, diff-stale-helpers) in traceability-validation.md. See constructorfabric#104. Verified: pytest (test_doc_index.py + test_toc.py: 166 passed, 100% coverage on touched doc_index files); full suite: 4825 passed, the same 12 pre-existing macOS-local/flaky failures as on constructorfabric#108/constructorfabric#109, none in files touched here; pylint and vulture clean; cfs validate 0 errors; spec-coverage thresholds met; infer_section_level/retrieval_sections re-verified against the real PDF-converted document that originally exposed the granularity bug -- still 12 correct sections.

…torfabric#109 - load_doc_index() returned a cached index whenever its etag matched, with no check that the cached shape matched what this version of the code expects. A cache written before section_level/retrieval_sections existed can still have a matching etag if the file hasn't changed since -- cmd_doc_index() would then hit a KeyError reading those fields on a legacy cache instead of a clean rebuild. Now treated the same as a stale cache: rebuilt, not returned as-is. - _frontmatter_has_description() treated a YAML block-scalar marker (`description: |`, `description: >-`, ...) as a usable value, when the real content -- if any -- belongs on indented lines below it, not on the marker's own line. Now checks the first non-blank following line for real indentation before counting it as a description. See constructorfabric#104. Verified: pytest (test_doc_index.py + test_toc.py: 172 passed, 100% coverage on touched doc_index files); full suite: 4831 passed, the same 12 pre-existing macOS-local/flaky failures as before, none in files touched here; pylint and vulture clean; cfs validate 0 errors; spec-coverage thresholds met; infer_section_level/retrieval_sections re-verified against the real PDF-converted document -- still 12 correct sections.

Two independently-testable JIT-retrieval mechanisms, both built on top of doc_index.py's retrieval_sections (constructorfabric#109) rather than re-deriving section boundaries themselves. tfidf.py: purely mechanical, no LLM call. Scores each retrieval section as sum(term-frequency x inverse-document-frequency) over a query's terms, and returns a margin/unambiguous confidence signal alongside the ranking, not just the ranking alone -- a routing layer built on top of this needs to know when the ranking itself isn't trustworthy. Verified against the real PDF-converted document referenced throughout this feature's design: the "KAPING" query is unambiguous (0.0016 vs 0.0000 everywhere else); the "zero-shot" query reproduces the documented real failure exactly (margin 1.06x, wrong section on top, since term frequency is normalized by section length and the real answer lives in a longer section than the one that wins). okf.py: deterministic cache/storage infrastructure, matching doc_index.py's own contract of containing no LLM-generated content -- writing an actual summary is an external caller's job (an agent, dispatched outside this codebase), same role as doc_index.annotate_section_summary one layer up. Tracks which concept files should exist against a document's *current* retrieval sections, detects staleness via the section hash recorded when a concept file was written (not a separate cache mechanism), and regenerates index.md deterministically from the manifest. The whole bundle lives under .cache/okf/ and is gitignored: unlike the content of a summary (expensive, real LLM tokens), the bundle not surviving a fresh clone just means it rebuilds the same way doc_index.py's own cache does. New CLI commands: `cfs tfidf-score <file> <query>`, `cfs okf-status <file>`. See constructorfabric#104. Verified: pytest (test_tfidf.py + test_okf.py + test_doc_index.py + test_toc.py: 227 passed, 100% coverage on all four new/touched command and util files); full suite: 4866 passed, the same 12 pre-existing macOS-local/flaky failures seen throughout this feature's development, none in files touched here; pylint and vulture clean; cfs validate 0 errors; spec-coverage thresholds met; a real end-to-end OKF write (bundle dir, manifest.json, index.md, concept file with frontmatter) run against a scratch project to confirm the mechanism works outside the test harness, not just inside it.

…ctorfabric#110 Adding commands/tfidf.py and commands/okf.py (both whole-file-scope claims, no instruction tracing) dropped the repo's spec-coverage granularity below its floor (0.4593 < 0.4600) -- the exact same failure shape constructorfabric#108 hit for utils/doc_index.py originally. commands/doc_index.py had the same gap already (pre-existing, just under the floor's margin until now). Added real @cpt-begin/@cpt-end instruction markers to all three command wrappers' main function and human-output formatter, registered as Supporting instructions under each module's existing algo ID. Along the way, instrumenting all three surfaced a real pylint duplicate- code finding: all three commands independently reimplemented the same "resolve a file-path CLI argument, emit the standard File-not-found ERROR result, return exit code 2" block. Extracted into ui.require_existing_file(), shared by all three (and available to any future single-file-argument command), registered under core-infra.md's existing render-info-human algo alongside ui.py's other generic helpers. See constructorfabric#104. Verified: pytest (test_tfidf.py + test_okf.py + test_doc_index.py + test_toc.py + test_ui_human_mode.py: 346 passed, 100% coverage on the three command files, 97% on ui.py full-suite); full suite: 4869 passed, the same 12 pre-existing macOS-local/flaky failures seen throughout this feature's development, none in files touched here; pylint and vulture clean (duplicate-code finding resolved, not suppressed); cfs validate 0 errors; spec-coverage thresholds met; TF-IDF re-verified against the real PDF-converted document after the refactor -- still reproduces the documented "zero-shot" margin (1.06x) exactly.

…torfabric#110 score_sections() already receives the resolved, correct file path as its own path parameter, but re-derived it a second time from index["path"] -- a string that round-tripped through the doc-index cache's JSON deserialization. SonarCloud's taint tracker (S2083) flags exactly this shape: a value crossing a file-content deserialization boundary before being used to construct a path for reading, rated BLOCKER regardless of real exploitability in a local CLI tool. The indirection was never needed -- get_or_build_doc_index() guarantees index["path"] == str(path.resolve()) by construction (see build_doc_index()), so reading from path.resolve() directly is exactly equivalent, removes the flagged taint flow entirely, and is simpler: no reason to bounce the path through the cache when the caller already has the real one in hand. See constructorfabric#104. Verified: pytest (test_tfidf.py: 15 passed, 100% coverage); full suite: 4869 passed, the same 12 pre-existing macOS-local/flaky failures seen throughout this feature's development, none in files touched here; pylint and vulture clean; cfs validate 0 errors; spec-coverage thresholds met; TF-IDF re-verified against the real PDF-converted document after the fix -- both the "KAPING" (unambiguous) and "zero-shot" (margin 1.06x) cases still reproduce exactly as documented.

…onstructorfabric#110 Cache schema validation didn't cover per-section hash, letting an intermediate-schema cache pass and later KeyError; OKF status trusted a manifest hash without checking the concept file still exists on disk; and the frontmatter description check matched an indentation-stripped line, letting a nested (non-root) description field suppress the warning.

…gate Combines the mechanical ingredients from PR constructorfabric#108-constructorfabric#110 (doc_index's structural index, tfidf's scoring, okf's bundle status) into a callable JIT-retrieval routing decision, and closes the two gaps findings.md left open: a heading-nav utility (the missing "grep + read enclosing section" mechanism the cascade's Tier 1 depends on) and the token-tracking/large- read confirmation gate, wired into the cascade's baseline fallback path instead of staying an unconnected prototype. The two design questions findings.md left explicitly unresolved are settled here: Tier 1's large-margin resolution requires TF-IDF's unambiguous signal rather than a numeric margin cutoff, since the only two real margins measured while designing this (infinite vs. 1.06-1.58x) don't support picking a specific threshold; and Tier 2 never recommends a known-stale/missing OKF concept file, falling back to baseline instead, since nothing in this codebase can perform a background rebuild.

In `@skills/studio/scripts/studio/utils/cascade.py`:
- Line 165: Update the recommendation logic in the cascade status flow so a
no-hit query with empty candidates never returns the OKF bundle based only on
bundle existence. Require all selectable concept entries to be verified current
before returning the “okf_bundle_current” recommendation; otherwise return the
existing non-OKF outcome, ensuring stale or missing concept files are not passed
to the external selector.
In `@skills/studio/scripts/studio/utils/decision_log.py`:
- Around line 471-476: The aggregation logic around methods.setdefault must skip
records whose payload is not a dictionary or whose tokens/lines values cannot be
converted to integers. Validate the payload before accessing get, catch
conversion errors, and continue without updating the current method entry for
invalid records; add a regression test covering both malformed payload shapes
and non-convertible numeric values.
In `@skills/studio/scripts/studio/utils/doc_index.py`:
- Around line 282-284: Update _has_schema_current_sections() to validate every
field consumed by cmd_doc_index(), including the presence and expected type of
sections, and return False for missing or malformed cache data even when
retrieval_sections is valid. Preserve the existing hash validation, and add a
regression test covering a matching-etag cache that omits sections.
In `@skills/studio/scripts/studio/utils/okf.py`:
- Around line 146-152: The manifest lookup in the section-processing logic
should use a stable section identity rather than line_start, and matched entries
should reuse their persisted concept filename instead of deriving one from the
current position. Update the lookup around by_line_start and _concept_filename
so unchanged sections continue matching after insertions, while new sections
retain the existing derived filename behavior.
- Line 98: Validate the parsed manifest structure in the manifest-loading
function before returning it: require the expected top-level shape and ensure
every entry contains the fields used by get_okf_status() and
write_concept_file(), returning None for invalid shapes including
{"entries":[{}]} and an empty list. Add regression coverage for both
malformed-entry and [] cases.
In `@skills/studio/scripts/studio/utils/tfidf.py`:
- Around line 85-86: Update the ranked-result guard in the TF-IDF routing logic
so a single result with a positive score returns unambiguous=True, while
preserving the existing None result and ambiguous behavior for empty,
non-positive, or multiple-result cases. Ensure route_tier1() can resolve this
sole-positive-result path without escalating.
In `@skills/studio/scripts/studio/utils/toc.py`:
- Line 759: Update the duplicate-key check in find_sections to normalize the
lookup key with lower() so headings differing only by case are treated as
duplicates, while retaining the original text for diagnostic messages. Add a
test covering case-only duplicate headings.
- Line 842: Update _BLOCK_SCALAR_RE to recognize block-scalar headers with
trailing comments and both chomping/indentation indicator orders, including | #
TODO and |2-. Ensure _frontmatter_has_description routes these recognized
headers through _block_scalar_is_empty so empty blocks still trigger
toc-missing-description, and add regression tests covering the commented header
and empty |2- block.

- Around line 91-95: Integrate decision_log.record_read into the production cfs

Human-readable usage-report and okf-status output silently drop several fields present in JSON
Severity: Major
Problem
The human-readable renderers for two new commands render only a subset of the data their own JSON output includes, so a person using the default human mode sees strictly less information than someone parsing --json. In commands/usage_report.py, _human_usage_report prints summary['path'], summary['exists'], summary['total_events'], and summary['runs'], but never touches summary['event_counts'], summary['first_ts'], or summary['last_ts'] — all of which utils/decision_log.py's summarize() computes and returns. Symmetrically, in commands/okf.py, _human_okf_status prints each entry's status, line_start, line_end, and heading, but never entry['concept_file'], even though utils/okf.py's get_okf_status() includes it in every entry.
How to reproduce
- In a Studio-adapted project with a non-empty decision log, run
cfs usage-report(human mode, the default) and separatelycfs usage-report --json. - Compare the two outputs' field coverage.
- Similarly run
cfs okf-status <file>andcfs okf-status <file> --jsonand compare per-entry fields.
Expected behavior
The human-readable view should surface the same substantive information as the JSON view (formatted for readability), or at minimum not silently omit fields a user would need to answer basic questions like "what event types were logged?", "over what time range?", or "which concept file does this section map to?".
Actual behavior
event_counts, first_ts, and last_ts never appear in human usage-report output; concept_file never appears in human okf-status output. These fields exist only in the JSON path.
cfs usage-report cfs usage-report --json
| |
v v
_human_usage_report() output dict
prints: path, { path, exists, total_events, runs,
exists, total_events, event_counts, first_ts, last_ts }
runs ^
(missing: event_counts, |
first_ts, last_ts) -----------/ <- silently dropped in human mode
Impact
Interactive users (the default, non-scripted use case) cannot see event-type breakdowns or log time range from usage-report, and cannot see which on-disk concept file corresponds to a given section from okf-status — forcing them to re-run with --json and parse manually, which defeats the purpose of a human-formatted mode.
Suggested correction
Add a line (or a few) to each human renderer: e.g. in _human_usage_report, print event-type counts and the first_ts/last_ts range next to the existing summary line; in _human_okf_status, include entry['concept_file'] alongside heading/status/line range in the per-entry line.
How to verify
Add/extend unit tests asserting the human-mode captured output (via capsys) contains the event-count breakdown and timestamp range for usage-report, and contains the concept filename for each okf-status entry.

No test exercises the argparse required-argument-omitted path for the seven new commands
Severity: Major
Problem
Across tests/test_cascade.py, tests/test_doc_index.py, tests/test_heading_nav.py, tests/test_okf.py, tests/test_read_gate.py, and tests/test_tfidf.py, every "missing" test exercises the case where a file path is supplied but doesn't exist on disk (asserting rc == 2 via ui.require_existing_file). None of these files contain a pytest.raises(SystemExit), meaning the distinct code path where a required positional CLI argument is omitted entirely — which argparse handles by printing usage and calling sys.exit(2) before the command's own logic ever runs — is untested for any of the seven new commands. Other, pre-existing test files in this same repo (e.g. tests/test_cli_integration.py) do cover this pattern, showing it's an established convention this PR's new tests don't follow.
How to reproduce
- Run
cmd_okf_status([])(or the CLI equivalent with no file argument) in a test. - Observe argparse's
SystemExit(2)fires beforeui.require_existing_fileis ever reached — a different failure mode than the "path given, file missing" case already tested. - Search the six new-command test files for
SystemExit/pytest.raises— none appear.
Expected behavior
Each new command's test suite should include at least one test asserting pytest.raises(SystemExit) when the required positional argument is omitted, distinguishing "no argument" from "bad/missing-file argument."
Actual behavior
Only the file-not-found path is tested; the missing-argument path has zero coverage for any of the 7 new commands.
cmd_okf_status([])
|
v
argparse.parse_args([]) -- required positional missing
|
v
SystemExit(2) <-- never reached by any existing test
(existing tests instead pass a nonexistent-file argv,
reaching ui.require_existing_file's own rc==2 path)
Impact
A future change to any of these commands' argparse.ArgumentParser setup (e.g. accidentally making the argument optional, or changing its name) could silently break required-argument enforcement without any test catching it.
Suggested correction
Add one small test per command file, e.g.:
def test_missing_required_argument(self):
with pytest.raises(SystemExit):
cmd_okf_status([])mirroring the pattern already used in tests/test_cli_integration.py.
How to verify
Run the new tests and confirm they fail if the argparse argument is temporarily made optional (nargs="?"), and pass against current code.

There was a problem hiding this comment.
Tier 2's returned schema has no stability guarantee documented, despite live internal consumers
Severity: Minor
Problem
route_query() in skills/studio/scripts/studio/utils/cascade.py builds its return dict ad hoc — {"query": query, **tier1}, then conditionally merges in tier2 and read_gate — and its docstring only describes control flow, with no note that the field names or their nesting are a stable contract. Two real consumers already key directly into these fields by name: commands/cascade.py's _human_retrieve reads data['tier'], data['reason'], data['candidates'], data['tier2']['recommendation'], data['tier2']['reason'], data['tier2'].get('okf_needs_rebuild'), and data['read_gate']['needs_confirmation']; tests/test_cascade.py asserts on result["tier"], result["tier2"]["recommendation"], and result["read_gate"]["needs_confirmation"]/["total_lines"]. Because the schema is undocumented as a contract, a future change to route_tier1/route_tier2's returned keys could silently break these consumers without any doc to flag the break.
How to reproduce
N/A — this is a documentation gap, not a runtime failure.
Expected behavior
The module or function docstring should state explicitly that the returned dict's shape (top-level tier/reason/candidates, plus conditional tier2 and read_gate sub-dicts with their own named fields) is a stable, versioned contract relied on by CLI formatting and tests, so future edits know to preserve or intentionally version-bump it.
Actual behavior
The docstring only narrates behavior with no mention of schema stability, versioning, or the existing internal consumers that depend on specific field names.
Impact
Low risk of an accidental breaking change to the internal CLI formatter and test suite when the cascade's return shape is modified, since nothing documents that these fields are load-bearing outside cascade.py itself. Purely a maintainability/documentation gap — no current functional defect.
Suggested correction
Add a short note to route_query's docstring (or a small schema block/comment) listing the guaranteed top-level keys and their consumers.
How to verify
Confirm the docstring update lists the exact keys used by commands/cascade.py::_human_retrieve and the assertions in tests/test_cascade.py, and that no behavior change is required (this is a comment-only fix).

OKF status reports "current" for a corrupted concept file it never reads
Severity: Major
Problem
get_okf_status() in skills/studio/scripts/studio/utils/okf.py determines each section's status purely from manifest metadata and a physical-presence check ((bundle_dir / concept_file).is_file()). It never opens or validates the concept file's actual content. When a manifest entry exists and its built_from_hash matches the section's current hash, the status is set to "current" without any read of the file the status vouches for.
How to reproduce
- Run the OKF pipeline against a document so a section gets a manifest entry and a written concept file, with
built_from_hashmatching the section's current hash. - Truncate, corrupt, or empty the concept file's content on disk (leave the manifest untouched).
- Call
get_okf_status(path).
Expected behavior
A concept file whose content is unreadable, truncated, or corrupted should not be reported as "current" — it should be flagged as needing regeneration (e.g. "missing" or a new "corrupt" status).
Actual behavior
The entry is reported "current", identical to a genuinely valid file, because only physical presence and manifest hash agreement are checked.
manifest.built_from_hash == section.hash? -- yes (untouched)
|
v
(bundle_dir/concept_file).is_file()? -- yes (corrupted but present)
|
v
status = "current" <-- content never read/validated
Impact
A caller trusting "current" status (e.g. the retrieval cascade in cascade.py) can serve a corrupted or empty concept file to a query as if it were a valid, trustworthy summary, producing a silently wrong answer with no detection mechanism.
Suggested correction
Add a minimal content-validity check before returning "current" — e.g. verify the file is non-empty and/or parses per its expected frontmatter/body structure, falling back to "missing" or a distinct "corrupt" status on failure.
How to verify
Add a test that writes a valid manifest entry with a matching hash but replaces the concept file's content with empty/garbage bytes, then asserts get_okf_status no longer reports "current" for that section.

Heading-nav substring search counts hits inside fenced code blocks as prose matches
Severity: Minor
Problem
find_sections/section_text in skills/studio/scripts/studio/utils/heading_nav.py count query occurrences via a plain case-insensitive substring count over each section's raw text. There is no fenced-code-block or inline-code-span awareness, even though utils/toc.py already implements fence-tracking (_fence_update) elsewhere in the same codebase.
How to reproduce
- Create a Markdown document with a retrieval section whose only occurrence of a query term is inside a fenced code block (e.g. a sample command or variable name), not in prose.
- Call
find_sections(path, query)with that query term.
Expected behavior
A term appearing only inside a code sample arguably should not count identically to a genuine prose hit, or at minimum this distinction should be a documented, tested design choice.
Actual behavior
The code-block occurrence is counted the same as a prose hit, with no fence-awareness and no test coverage for this case in tests/test_heading_nav.py.
Impact
Low — this can inflate hit_count and, in edge cases, cause a section to be selected by Tier 1 routing based solely on an incidental code-sample match rather than genuine prose relevance.
Suggested correction
Reuse the existing _fence_update fence-tracking from utils/toc.py to exclude fenced code blocks (and optionally inline code spans) from the substring count, or explicitly document this as an accepted limitation if intentional.
How to verify
Add a test with a section containing the query term only inside a fenced code block and assert the expected hit-count/match behavior once a decision is made.

Cache/manifest read failures are logged only at an unreachable debug level
Severity: Minor
Problem
Six new except blocks (utils/doc_index.py lines 76, 266, 315, 370; utils/okf.py lines 63, 100) catch OSError/json.JSONDecodeError, log via logger.debug(...), and silently fall back (return None / disable caching). The CLI's own logging setup pins the studio logger at WARNING, and there is no --debug/--verbose flag anywhere in the CLI to lower that threshold.
How to reproduce
- Inspect
cli.py's logging configuration, which sets the studio logger toWARNINGunconditionally. - Search the CLI for any flag that adjusts log level — none exists.
- Trigger one of the six except paths (e.g. make the doc-index cache file unreadable/corrupt) and observe no diagnostic output at any log level a user can enable.
Expected behavior
A real, unexpected failure (permission error, disk corruption, race condition) reading or writing the cache should be visible to a user who wants to diagnose why caching silently stopped working.
Actual behavior
The failure is logged at DEBUG, a level that is structurally unreachable through the CLI's own logging configuration, so it is fully invisible in practice.
Impact
Silent cache degradation (e.g., permission issues, unexpected corruption) is undiagnosable without editing source code or attaching a custom log handler.
Suggested correction
Either expose a --debug/--verbose CLI flag that lowers the logger threshold, or log unexpected fallback conditions at WARNING (reserving DEBUG only for fully-expected states like "no Studio directory found").
How to verify
After the fix, trigger one of the six fallback conditions and confirm the resulting message is visible through the CLI's normal (non-flag) output or via a documented verbosity flag.

Unhandled decode error crashes every file-consuming CLI command on binary or non-UTF-8 input
Severity: Major
Problem
_read_with_stable_etag() in utils/doc_index.py calls path.read_text(encoding="utf-8") with no exception handling. Every command that consumes a file (doc-index, heading-nav, tfidf-score, retrieve, read-gate, and okf-status once inside a Studio project) routes through this function via get_or_build_doc_index. The CLI's top-level dispatcher only catches SystemExit, so nothing intercepts a UnicodeDecodeError.
How to reproduce
- Create a file with invalid UTF-8 bytes, e.g.
python3 -c "open('bad.md','wb').write(b'\xff\xfe\x00Hello world')". - Run
doc-index(orheading-nav,tfidf-score,retrieve,read-gate) with that file. - Observe the process crash with a raw Python traceback and exit code 1.
Expected behavior
The CLI should catch the decode failure and print a clean, structured error (consistent with its other file-validation error paths), exiting with a controlled non-zero code.
Actual behavior
An unhandled UnicodeDecodeError traceback is printed straight to stderr, exposing internal file paths and stack frames, for any binary or non-UTF-8 file passed to any of these commands. Reproduced live against all five directly-testable commands.
Impact
Any binary file, PDF, image, or non-UTF-8-encoded document handed to these commands crashes the tool ungracefully instead of failing cleanly.
Suggested correction
Wrap the read_text call in _read_with_stable_etag (or at the CLI dispatch boundary) with a try/except UnicodeDecodeError that reports a standard file-validation error, matching the existing pattern for missing files.
How to verify
Re-run the reproduction steps above against each of the six commands after the fix; each should print a structured error message and exit non-zero without a raw traceback.

Persistence functions' failure signal is discarded, so callers report false success
Severity: Minor
Problem
save_doc_index() has no return value (declared to return None) and no-ops silently when a file is outside a Studio project. It's called from get_or_build_doc_index and annotate_section_summary, with no signal available to detect the no-op. annotate_section_summary then unconditionally returns True. Similarly, save_okf_manifest() returns bool (False on no-op), but its only call site, write_concept_file(), discards the result and unconditionally returns True.
How to reproduce
- Call
annotate_section_summary(path, line_start, summary)for a file located outside any Studio-adapted project (so the underlying cache/bundle path resolves toNone). - Observe the function returns
Trueeven thoughsave_doc_indexnever wrote anything to disk. - Similarly call
write_concept_file(...)outside a Studio project and observe it returnsTrueeven thoughsave_okf_manifestreturnedFalseand no manifest was persisted.
Expected behavior
A caller should be able to tell, from the return value, whether the summary/manifest was actually persisted.
Actual behavior
Both functions report unconditional success regardless of whether the underlying save actually wrote anything.
Impact
An external caller (e.g., an LLM-driven summarization pass) believes a summary or concept file was saved when it silently wasn't, leading to repeated wasted work (re-summarizing the same section every run) with no error surfaced.
Suggested correction
Have save_doc_index return a bool matching save_okf_manifest's convention, and have both annotate_section_summary and write_concept_file propagate that result instead of returning True unconditionally.
How to verify
Call both functions against a file outside a Studio-adapted project and confirm they now return False/report failure instead of True.

--margin-threshold accepts values that defeat the cascade's own documented safety margin
Severity: Major
Problem
commands/cascade.py's --margin-threshold argument uses type=float with no validator, so any float — negative, zero, or non-finite — reaches utils/cascade.py's route_tier1(). The module's own docstring states the design basis explicitly: real measured data showed only an infinite margin was safe on a correct pick, while finite margins of 1.06x-1.58x still occurred on two independently wrong picks — "unambiguous is safe, anything finite isn't yet proven safe." A negative or near-zero --margin-threshold makes tfidf_result["margin"] >= margin_threshold true for virtually any margin, so agree_large_margin fires and Tier 1 returns a confident "resolved" instead of escalating — exactly the case the module's design notes say is unsafe. (A nan threshold does not have this effect: NaN comparisons are always false, so margin >= nan never fires and Tier 1 simply falls back to the conservative unambiguous-only path — that is a fail-safe no-op, not a defeat of the escalation logic.) The codebase already has an established pattern for exactly this hazard: commands/eval.py's _compliance_arg rejects any value where not math.isfinite(parsed) before accepting it as an argparse type. cascade.py does not reuse or mirror that pattern.
How to reproduce
- Run
cfs cascade <file> <query> --margin-threshold -1. - Construct or find a query where heading-nav and TF-IDF agree on a section but with only a small measured margin (not
unambiguous). - Observe
route_tier1returns{"tier": "resolved", ...}instead of{"tier": "escalate", "reason": "diffuse_margin", ...}.
Expected behavior
A negative, zero, or otherwise out-of-range --margin-threshold should be rejected at the CLI boundary, consistent with the project's own stated design intent that no finite margin has yet been proven safe.
Actual behavior
Any float, including negative values, is silently accepted and used directly in the safety-relevant comparison, letting an operator (accidentally or otherwise) force Tier 1 to resolve confidently on cases the module's own design notes classify as unsafe.
Impact
Silently weakens the one documented safety guard in the cascade's decision logic, with no error or warning at invocation time. Given this is optional/off-by-default, impact is limited to callers who explicitly pass the flag, but there is nothing stopping an unvalidated or accidentally-negative value from being passed.
Suggested correction
Add a small validator function for --margin-threshold (mirroring _compliance_arg in commands/eval.py) that requires math.isfinite(value) and value > 0, and use it as the argparse type=.
How to verify
Add a unit test asserting the CLI rejects --margin-threshold -1, --margin-threshold 0 with a clear argparse error, and that a valid positive finite value still passes through to route_tier1 unchanged.
…on PR constructorfabric#111 - cascade.py: Tier 2 no longer recommends OKF for a no-candidate (row 1) query unless every section in the bundle is current, not just some -- the external file-selector could otherwise land on a stale/missing one. - okf.py: manifest entries are now matched by document position instead of line_start, so unrelated content changing size elsewhere in the document no longer misreports an untouched section as missing; and load_okf_manifest validates entry shape before returning, so a malformed manifest (hand-edited or from a schema this module predates) triggers a clean rebuild instead of a KeyError in a consumer. - tfidf.py: a single retrieval section with a positive score is now unambiguous (nothing to be confused with), instead of always escalating. - decision_log.py: summarize_reads() skips a read event whose payload isn't a dict, or whose tokens/lines aren't numeric, instead of raising. - doc_index.py: cache schema validation now also requires "sections", closing the same class of gap already fixed for "hash" on PR constructorfabric#110. - toc.py: the YAML block-scalar header regex now accepts both indicator orders and a trailing comment, matching the real YAML 1.2.2 grammar.

Validate manifest field types before returning the manifest.
A manifest such as {"entries": [{"position": [], "heading": "", "concept_file": "", "built_from_hash": ""}]} passes this check. get_okf_status() then raises TypeError when it uses the list as a key in by_position.
Require a positive integer position and string values for heading, concept_file, and built_from_hash. Add regression coverage for invalid field types.

Summary
Stacked on #108, #109, and #110 (still open) — combines the mechanical ingredients those PRs built (
doc_index.py's structural index,tfidf.py's scoring,okf.py's bundle status) into a callable two-tier JIT-retrieval routing decision, and closes the two remaining gaps from the design document (see #104): the missing heading-nav mechanism Tier 1 depends on, and the token-tracking/large-read confirmation gate, which is now actually wired into the cascade's baseline fallback path instead of sitting as an unconnected prototype.utils/heading_nav.py+commands/heading_nav.py(cfs heading-nav) — a case-insensitive literal-substring search of a query against each retrieval section's own text, mirroringgrep -i— the "grep the query's words, then read the enclosing section" mechanism the design's Tier 1 table needs but nothing in the codebase implemented yet.utils/cascade.py+commands/cascade.py(cfs retrieve) —route_query()runs Tier 1 (heading-nav + TF-IDF agreement/margin), and only escalates to Tier 2 (OKF vs. baseline) when Tier 1 can't resolve confidently. Verified end-to-end against the real 166-page source PDF this design was built against, reproducing the three documented real scenarios exactly: KAPING resolves at Tier 1 (unambiguous), "making up" escalates (heading-nav zero hits), "zero-shot" escalates (diffuse margin, not unambiguous).utils/read_gate.py+commands/read_gate.py(cfs read-gate) — the large-read confirmation threshold check (default 5,000 lines, the real number measured designing this), now wired intoroute_query()'s baseline fallback so a Tier 2 baseline recommendation always reports whether it crosses the confirmation threshold.decision_log.pygets a new"read"event,record_read(), andsummarize_reads()— activating its existing (previously uncalled)summarize()/read_events()read API — pluscommands/usage_report.py(cfs usage-report) for the per-method token table the design's token-tracking prototype produced.doc_index.pygains a small sharedsection_text()helper (promoted out oftfidf.py's private copy) soheading_nav.pydoesn't duplicate the section-slicing logic.Two design decisions this PR resolves
Tier 1's margin threshold: the design's two real data points (an infinite/unambiguous margin on a correct pick, and a 1.06x-1.58x margin on two independently wrong picks) don't support a specific numeric cutoff.
route_tier1()requiresunambiguous=Truefor a large-margin Tier 1 resolution by default; amargin_thresholdparameter exists to opt into a numeric cutoff later, once there's real evidence for one.Staleness policy (block vs. serve-stale-and-rebuild-async): this codebase has no background job runner and no LLM-calling capability anywhere (by design — see
okf.py's own docstring).route_tier2()never recommends an OKF concept file it knows is stale/missing for Tier 1's candidate section; it falls back to baseline withokf_needs_rebuild: trueinstead, since serving a known-stale pointer with no mechanism to ever correct it would be a silent wrong answer.A real bug was caught and fixed during manual verification before writing tests:
get_okf_status()returns one entry per retrieval section even when nothing has ever been summarized (allstatus: "missing"), so an earlybundle_existscheck based on "bundle_dir resolves and entries is non-empty" was always true inside a Studio project — fixed to require at least one entry withstatus != "missing".Test plan
