Completes the #963 coverage taxonomy: alongside the best-effort FAILURE
signals (parse_partial, skipped), the report now lists what was
deliberately NOT indexed — a deterministic, by-design class, never mixed
into the failure surfaces.
- discover: file skips are classified by reason (gitignore / cbmignore /
skip-list / ignored-suffix / fast-pattern / size-cap) and collected via
the new cbm_discover_ex2 (per-file entries capped at 2000 with the
uncapped total reported — truncation is explicit, never silent; whole
excluded subtrees stay exhaustive as before). Unsupported-extension
files are deliberately NOT recorded: no grammar for an extension is
not an ignore decision, and listing every README/asset would drown
the signal
- pipeline: ignored files captured per run (full + incremental) and
persisted into the index_coverage table as not_indexed_file rows,
excluded dirs as not_indexed_dir; incremental runs rewrite the
by-design set fresh from discovery instead of carrying old rows
- store: the deleted-file prune exempts not_indexed_* (deliberately
unindexed paths never have hash rows); the missed shadow graph keeps
showing FAILURES only — the UI's report-an-edge-case callout can
never fire for gitignored paths, and a project whose only coverage
rows are by-design gets no miss graph at all
- mcp: index_repository response gains not_indexed_files {files, count,
truncated, note} (dirs stay under excluded); index_status's coverage
report gains a not_indexed section (dirs + files + note) and no longer
lumps by-design rows into skipped; tool descriptions updated — the
by-design class is presented as deliberate and deterministic (change
the ignore rules and re-index), with no best-effort hedging
- tests: e2e guard (gitignored file + dir reported with reasons on both
surfaces, failure surfaces stay clean, missed graph excludes them,
rows survive an incremental re-index, ignored constructs genuinely
absent from the graph); store unit test covers the prune exemption
and shadow-graph exclusion
