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.

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.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- 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

The hybrid approach (Claude's native Explore agents using codegraph tools)
is more effective than a custom explore tool because Explore agents already
know what format the main session needs.

The installer runs `npm install -g @colbymchenry/codegraph` so users
can simply run `codegraph init -i` instead of the full npx command.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Users running via npx don't have the codegraph command installed
globally. Update installer message and README to use
npx @colbymchenry/codegraph init -i instead.

Change static import to dynamic import() for @xenova/transformers
which is an ESM-only package. This fixes ERR_REQUIRE_ESM when
running via npx in CommonJS environments.

Updated documentation to recommend instructing Explore agents to use
CodeGraph tools (search, callers, callees, context) for faster code
exploration instead of file scanning.
Benchmark results show ~30% fewer tokens and ~25% fewer tool calls
when Explore agents leverage CodeGraph for graph-based lookups.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Instead of returning file paths for Claude to read separately,
codegraph_explore now:
- Reads relevant files internally using fs
- Extracts code snippets for key symbols (functions, types, APIs)
- Includes the code directly in the response
- Returns a synthesis with data flow and key code included
This matches native explore agent behavior where file reading
happens in the sub-agent context, keeping main context clean.
