📝 WalkthroughWalkthroughAdds a cached Markdown document-index CLI command and four warning-only TOC readiness checks. The changes include cache invalidation, section summaries, configurable section limits, new warning codes, CLI wiring, and tests. ChangesDocument indexing
TOC readiness validation
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The PR adds cached document indexing and warning-only TOC readiness checks, but the cache can return stale headings and section ranges after certain edits, while absolute-path usage can select the wrong project cache and readiness warnings can be incomplete. These are bounded but concrete merge-readiness risks requiring owner follow-up before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Inline comments:
In `@skills/studio/scripts/studio/utils/doc_index.py`:
- Around line 34-42: The document-index cache must validate file changes using
metadata rather than the content-insensitive _compute_etag formula or read_text
on every hit. Update load_doc_index and its cache metadata to store st_mtime_ns
and st_size, call Path.stat() before loading a cached index, and reuse the cache
only when both values match; add a regression test replacing a heading with
same-size, same-line-count text to verify stale headings and section ranges are
not returned.
- Line 54: Update the Studio directory lookup in the doc-index flow to call
find_studio_directory with path.resolve().parent instead of Path.cwd(), ensuring
the cache is resolved from the indexed file’s project directory.
In `@skills/studio/scripts/studio/utils/toc.py`:
- Around line 856-859: Update the frontmatter handling in the description-check
flow around _find_frontmatter_end so it suppresses the warning only when the top
YAML block contains a non-empty accepted description field. Do not return early
for frontmatter containing only unrelated fields such as title; preserve the
existing line-count and warning behavior otherwise.
- Around line 987-990: Update the readiness checks around
parse_headings_with_lines and _check_duplicate_heading_titles,
_check_heading_depth_jumps, and _check_section_lengths to parse all heading
levels without applying max_heading_level. Retain max_heading_level exclusively
for TOC validation, and ensure ignored headings are included when determining
section boundaries for length validation.

…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.

Summary
toc.pygains four warning-only JIT-retrieval readiness signals: duplicate heading titles, heading depth jumps, oversized sections (configurable--max-section-lines, default 300), and a missing top-of-file description — structural properties that make heading-based JIT retrieval harder without invalidating otherwise-valid documents.doc_index.py(util +cfs doc-indexcommand): a cached, etag-invalidated structural index (headings + section line ranges) so navigation reads a file's structure once per file, not once per query, with anannotate_section_summaryhook for a future LLM caller to attach per-section summaries.See #104.
