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Pin to commit 042119e for reproducible builds (npm v0.0.1 is outdated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

- 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 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.

- Add 'svelte' to Language type, DEFAULT_CONFIG includes, grammars, and config validation
- Add SvelteExtractor that extracts <script> blocks and delegates to TS/JS TreeSitterExtractor
- Add Svelte framework resolver for runes ($state, $derived, $effect, etc.), store auto-subscriptions, SvelteKit module aliases ($app/*, $env/*, $lib/*), and SvelteKit route detection
- Update README to list Svelte and Dart in supported languages

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.

Node insertion used plain INSERT which crashes on duplicate IDs.
In large C/C++ projects, tree-sitter can produce duplicate nodes for
the same symbol (e.g. typedef struct where both struct_specifier and
type_definition resolve to the same name/kind/line, or multiple
anonymous constructs on the same line).
- Change nodes INSERT to INSERT OR REPLACE (idempotent, same data)
- Change edges INSERT to INSERT OR IGNORE (skip duplicate edges)
The node ID is sha256(filePath:kind:name:line) which already uses full
relative paths, so cross-directory collisions are not the issue.

sqlite-vss fails to compile on Windows — moving it to optional lets
install succeed while the code already falls back to brute-force
vector search. tree-sitter-liquid is removed entirely as it has ABI
incompatibility with tree-sitter 0.22+ and Liquid is handled by the
built-in regex extractor.

Covers arrow function extraction, best-candidate resolution, graph
traversal direction fix, MCP symbol disambiguation, output truncation,
CLI uninit command, and more. Tests requiring better-sqlite3 native
bindings are conditionally skipped.

- Add findSymbol() helper that prefers exact name matches and notes
alternatives when multiple symbols share the same name
- Add output truncation (15K char cap) to prevent context window bloat
- Apply to callers, callees, impact, node, search, and files tools

Exposes the existing uninitialize() method via `codegraph uninit [path]`.
Includes confirmation prompt (skippable with --force) before deleting
the .codegraph/ directory.

- Fix arrow function extraction: explicitly call extractFunction() for
arrow functions/function expressions in variable declarations instead
of silently skipping them (all 6 arrow function tests now pass)
- Best-candidate resolution: collect candidates from all strategies and
return highest confidence match instead of first match
- Fix graph traversal 'both' direction: correctly determine next node
for mixed incoming/outgoing edges in BFS and DFS

- SQLite performance pragmas: synchronous=NORMAL, 64MB cache,
memory temp store, 256MB mmap (safe with WAL mode)
- Batch insert for unresolved refs: single transaction instead of
N individual inserts per file
- Symbol caching (warmCaches): pre-load all nodes into memory maps
before resolution, eliminating repeated SQLite queries per ref
- Async file I/O: fs.stat/readFile in indexFile() are now non-blocking
- Denormalize filePath/language onto UnresolvedReference: avoids N
node lookups during resolution, with schema migration v2

- Fix Float32Array embedder bug: was creating zero-filled array instead
of copying data from TypedArray-like objects
- Fix VSS search query: use subquery pattern so LIMIT applies before JOIN
- Pin tree-sitter versions: remove caret ranges for ABI stability, add
overrides to lock tree-sitter core at 0.22.4
- Lazy grammar loading: load native bindings on first use per language
instead of all at startup, so one missing grammar doesn't affect others
- Remove stale src/extraction/queries copy from copy-assets script
