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.

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Pin to commit 042119e for reproducible builds (npm v0.0.1 is outdated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

- 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 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

- 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

Implements security improvements inspired by PR #16 (credit: MO2k4):
- Add validatePathWithinRoot() to prevent path traversal attacks in
extraction and context building
- Clamp MCP tool inputs (limit, depth, maxDepth) to sane ranges
- Use atomic writes (temp file + rename) for config saves
- Add symlink cycle detection in directory scanning to prevent infinite loops
- Replace all JSON.parse calls in db/queries.ts with safeJsonParse fallbacks
to handle corrupted database metadata gracefully
- Add cross-process FileLock for DB write operations (indexAll, indexFiles,
sync) to prevent concurrent writes from CLI, MCP server, and git hooks
- Remove unused path import from context/index.ts
