Persist the parse-coverage signal outside the graph and make the misses
queryable both as a list and as a graph.
- store: new index_coverage table (project, rel_path, kind, detail) —
coverage is metadata ABOUT the graph and never mixes into the graph
tables; replace/get/free APIs with a deleted-file prune keyed off
file_hashes (the live-file set)
- store: materialize a derived miss graph under the shadow project
"<project>::coverage" (Project -> Folder chain -> File{kind,detail},
CONTAINS_FOLDER/CONTAINS_FILE edges), rebuilt from the table inside
the same transaction on every replace; invisible to list_projects
(which scans the cache directory, not the projects table)
- pipeline: coverage is written in the same persist step as every other
post-dump SQL write (hashes, ADR, FTS). Full runs replace the whole
set; incremental runs merge rows surviving from files not re-extracted
with this run's fresh entries, so a fixed file's flag clears and
deleted files prune automatically
- mcp: new get_index_coverage tool (per-project parse_partial + skipped
lists with the best-effort note); query_graph gains graph="coverage"
to run the same cypher against the miss graph; the File-node property
marker from the previous commit is dropped in favor of the separate
table — the code graph gains no coverage rows
- wording: constructs in flagged ranges MAY be missing — tree-sitter
error recovery still salvages some (verified: a function inside a
flagged #ifdef region and even a broken def were still extracted)
- tests: store round-trip/prune/shadow-graph unit test; e2e asserts the
response fields, the advertised coverage-graph query, code-graph
purity, and that the flag clears after the file is fixed (incremental
route)
