Replace native tree-sitter with web-tree-sitter + tree-sitter-wasms for
universal cross-platform support. Add node-sqlite3-wasm as a fallback
when better-sqlite3 native bindings aren't available. Move better-sqlite3
and sqlite-vss to optionalDependencies so installs never fail.
Fix installer to use npx fallback when global npm install fails, so MCP
config, hooks, and quick-start instructions all work without the bare
codegraph command in PATH.
Fix tests: update schema version expectation, fix db test paths and
method names, extract MAX_OUTPUT_LENGTH as module constant, normalize
Windows path separators in import resolver.
Two major optimizations for the ref resolution phase:
1. Cache extractImportMappings() results per file path — previously
re-read and re-parsed the source file for every single ref from
that file (e.g. 100 refs from one file = 100 identical file reads)
2. Replace linear scan in matchFuzzy() with a lazily-built
case-insensitive Map index — O(1) lookup instead of iterating
all function/method/class nodes for every unresolved ref.
Also drop low-value prefix matching (confidence 0.3).

These are project-specific directories and should be configured per
project in .codegraph/config.json, not hardcoded globally. Delphi-
specific excludes (__history, __recovery, *.dcu) remain as global
defaults since they are analogous to __pycache__ for Python.

Replace this.nodes.find() with a lazily-built Map<name, nodeId> for
matching implementation bodies to their declarations. Reduces per-file
complexity from O(methods × nodes) to O(nodes) for index build + O(1)
per lookup.

Add _libs/**, libs/**, __history/**, __recovery/**, and *.dcu to
default exclude list. Delphi projects store external dependencies
in _libs/ or libs/ (often as Git submodules) and these should not
be indexed — same as node_modules for JS projects.

Two optimizations that eliminate the O(n²) bottleneck:
1. Add Pascal built-in filtering to isBuiltInOrExternal() — skips
resolution attempts for System.*, Vcl.*, Fmx.* and ~60 common
RTL identifiers (WriteLn, Create, Free, TObject, etc.)
2. Cache getNodesByKind() results during warm cache phase — matchFuzzy()
was calling the database 3 times per unresolved reference instead
of using the in-memory cache that warmCaches() already builds.

Some .dpr templates use "program;" without a name, which produces an
empty moduleName in the AST. Fall back to the filename (without extension)
to prevent nodes with empty names that cause downstream FK constraint errors.

Update language count (17+ → 18+), add Pascal/Delphi row to the
supported languages table, and include Pascal in CLAUDE.md language list.

Remove Delphi/ planning folder (concept docs, fixtures, resolution notes)
that served as implementation guidance. Add DELPHI-SUPPORT.md describing
the integration for stakeholder review: motivation, feature matrix,
architecture decisions, and test coverage.

Align with project convention: all tree-sitter grammars are optional.
Pin to commit 042119e for reproducible builds (npm v0.0.1 is outdated
and incompatible with Node.js v24 due to NAN bindings).

The resolving refs phase stalled on large projects (3400+ files, 38k+ nodes)
because matchFuzzy loaded ALL functions/methods/classes per ref, import
mappings were re-extracted per ref, and fileExists hit disk every call.
Add kindCache, lowerNameCache, importMappingCache, and knownFiles set to
warmCaches(). Rewrite matchFuzzy to use O(1) lowercase index lookup instead
of 3x getNodesByKind scans. Cache import mappings per file. Pre-build file
existence set from the index for O(1) fileExists checks.
Fixes#28 - Python site-packages directories (e.g.
audio_tools/python/Lib/site-packages/) were not excluded by default,
causing massive index bloat and FOREIGN KEY failures when indexing
large libraries like tensorflow. The FK crash itself was already fixed
via INSERT OR IGNORE, but excluding these directories prevents the
bloat in the first place.
- Remove getNodesByIds, getNodesByKinds (zero callers)
- Remove getFileHashMap, getFileSyncMap (zero callers)
- Remove getDynamicStmt cache (only used by removed batch methods)
- Revert getStaleFiles to simple implementation (zero callers, no need to optimize)
- Remove intent field from SearchOptions (never read in search logic)
- extraction/index.ts: use picomatch with static import (replacing
dynamic require) and keep normalizePath for other call sites
- utils.ts: keep normalizePath from main, take PR's PID-based FileLock
Both functions have zero callers — dead code on arrival. Remove them
and their tests (9 tests) to keep the module focused on what's
actually used: search term extraction, path relevance scoring, and
kind bonuses.
- Remove extractFunctionVariable() and its dispatch (already handled by extractVariable)
- Remove dead getGrammar() export (zero callers)
- Deduplicate indexFile by delegating to indexFileWithContent
- Remove redundant arrow function variable extraction tests (covered by existing suite)
- Create file-kind nodes for each parsed source file
- Add isInsideClassLikeNode() for method vs function detection
- Extract arrow functions and function expressions from variable declarators
- Batch file I/O with FILE_IO_BATCH_SIZE=10 using Promise.all
- Add symlink cycle detection with visitedDirs Set in scanDirectory
- Add lazy grammar loading with exported getGrammar() function
- Add indexFileWithContent() for pre-read content processing
- Add tests for file nodes and arrow function extraction
- Add provenance column on edges for tracking how edges were created
- Add project_metadata table for version/provenance tracking
- Make unresolved_refs file_path/language NOT NULL with defaults
- Add composite indexes for unresolved_refs and edges.provenance
- Update v2 migration to handle all new schema additions
- Record schema version on initialize to prevent re-migration
- Add dynamic prepared statement cache (getDynamicStmt) for varying SQL
- Add batch methods: getNodesByIds, getNodesByKinds, getFileHashMap, getFileSyncMap
- Add project metadata methods: getMetadata, setMetadata, getAllMetadata
- Optimize getStats to use single aggregate query
- Optimize getStaleFiles to use temporary table JOIN
- Add provenance parameter to getOutgoingEdges
- Add intent field to SearchOptions type
- Add validateProjectPath() to reject sensitive system directories
- Add isPathWithinRoot/isPathWithinRootReal for symlink-aware path checks
- Replace hand-rolled glob-to-regex with picomatch to prevent ReDoS
- Add isSafeRegex() to reject custom patterns with nested quantifiers
- Replace FileLock with PID-tracking version that detects stale locks
- Add symlink detection in removeDirectory/listDirectoryContents
- Add subdirectory name validation in ensureSubdirectory
- Add atomicWriteFileSync and corrupted file backup in config-writer
- Add MCP input validation (validateString) for all tool handlers
- Fix CLAUDE.md section replacement to handle ### subsections correctly
Normalize paths to forward slashes in matchesGlob() and scanDirectory()
so glob exclude patterns work on Windows. Add getGitIgnoredDirectories()
using git ls-files to skip .gitignore'd directories during indexing.

All grammar packages now have compatible peer deps with tree-sitter 0.21.x,
resulting in zero warnings during npm install. Downgraded grammars:
c 0.24.1→0.23.2, php 0.24.2→0.23.11, python 0.23.6→0.23.4,
rust 0.24.0→0.23.1, swift 0.7.1→0.6.0.

Reduces peer dependency warnings during install by upgrading grammars that
have newer versions accepting ^0.22.x: c 0.23.4→0.24.1, php 0.23.11→0.24.2,
rust 0.23.2→0.24.0. Python 0.23.6 and swift 0.7.1 already compatible.

tree-sitter-kotlin doesn't ship prebuilt binaries for win32-x64, causing
npm install to fail on Windows without Visual Studio. All grammars are now
optional since the runtime already handles missing parsers gracefully.

PostToolUse(Edit|Write) marks the project dirty via .codegraph/.dirty,
and Stop syncs only if dirty — batching all edits into one sync per
Claude response. The installer now writes these hooks to settings.json.
