The precision release: a rewritten reference resolver, two new MCP tools, a
security + robustness hardening pass, and a broad performance sweep. Schema
advances v6 → v10 (auto-migrated on first run).Three-binary release:
code-index-mcp(MCP stdio bridge — the usual entry),
code-index-daemon(long-lived watcher + RPC server, auto-spawned), and
code-index(CLI: init, index, watch, doctor, link).Highlights
- Two new MCP tools (10 → 12).
repo_map— a personalized PageRank over the reference graph, token-budgeted, for "what matters here" orientation.changed_symbols— a git-diff-aware report of which symbols a working-tree change touches.
- Three-tier reference resolver. Name resolution now applies a visibility gate, a same-file preference, then an import-based boost — lifting resolution on this repo from 16.2% → 21.4% while eliminating a class of false positives (qualified calls like
Vec::new()no longer take shortcuts). - Visibility-aware indexing across all 6 languages (Rust, TypeScript/JavaScript, Python, C#, PHP, Ruby).
Features
repo_map: personalized PageRank over the ref graph, token-budgeted, with deterministic attribution and target-sensitive edge caching.changed_symbols: git-diff-aware symbol report.- Reference roles v1: a Test role bit, with
exclude_testsonfind_references. response_format=concise|detailed, corrective hints, and pinned pagination on tool responses.- Outline-hash resolve firewall: per-file Skipped / Scoped / Full resolve scopes so edits only re-resolve what changed.
Security & robustness
- Closed a git-config RCE: a hostile repository can no longer inject code via
diff.external/fsmonitor/hooksPath; textconv is disabled. - Fixed a UTF-8 boundary panic and a leaf-symlink path-escape in the MCP server.
- Daemon RPC capability-token auth: a random 128-bit token (0600 file) authenticates every RPC; mismatches are rejected in constant time.
- Integrity-check now tolerates transient FTS5 lock contention (not treated as corruption); idle shutdown keys on activity age.
- Writer-thread death is now surfaced so the daemon exits and is respawned;
--no-daemonalways reconciles so a partial index self-heals.
Performance
search_symbolsrewritten to be index-driven; newm0009search indexes (NOCASE name, file-span) andm0010indexed_atindex.entry_pointscollapsed to a single scan; cross-project fan-out (search/repo_map) now runs concurrently.- Prepared-statement caching on the writer hot path; per-file and per-query allocation cut across indexer/daemon/mcp.
Schema
- Migrations m0006 – m0010 (schema v6 → v10):
symbols.visibility,refs.roles,files.outline_hash, crash-safe persistent resolve-pending tables, qualified-ref flag, and the search /indexed_atindexes. Existing databases auto-migrate on first run (one Full resolve pass after upgrade, by design).
