Now that distribution will bundle a Node 24 runtime, node:sqlite (real SQLite
with WAL + FTS5) is always available. Collapse the three-backend adapter to
node:sqlite only and remove the machinery the other two needed:
- Remove better-sqlite3 (optionalDependency) and node-sqlite3-wasm (dependency).
- Remove WasmDatabaseAdapter, the named->positional param translation, the
SQLITE_BUSY read-retry, the wasm fallback banner, the backend env override,
and the native/node-sqlite/wasm selection chain.
- createDatabase now opens node:sqlite directly, with a clear error pointing at
the bundled release / Node 22.5+ when the module is absent.
- NodeSqliteAdapter.close() is idempotent and pragma() supports { simple }, to
match the better-sqlite3 behavior callers relied on.
- status (CLI + MCP) reports the single node:sqlite backend; journal-mode
diagnostics and the getCodeGraph single-connection fix are retained.
- Tests repointed off better-sqlite3 onto node:sqlite.
Net -1044 lines. Running from source now requires Node 22.5+.

better-sqlite3 ^11.0.0 (latest 11.10.0) ships no prebuilt binary for
Node 24's ABI (node-v137) and predates Node 24, so every Node 24 install
silently fell back to the 5-10x-slower WASM backend. Bump to ^12.4.1 —
the first 12.x with the Node 24 prebuild — and raise the engines floor to
Node 20 (Node 18 is EOL and dropped from better-sqlite3 12.x prebuilds).
Verified on macOS Node 24.15.0 (ABI 137): prebuilt binary used with no
compiler (installs even with CC/CXX sabotaged), `codegraph init -i` shows
no WASM banner, and `codegraph status` reports Backend: native. 639/639
tests pass on Node 22.

* feat(mcp): line numbers in explore output + per-file cluster fixes
Follow-up to #185. Three changes to codegraph_explore:
1. Source sections now carry cat -n style line-number prefixes
(<num>\t<code>), so the agent can cite file:line straight from the
payload instead of re-Reading the file just to recover a line number.
Isolated A/B: the no-line-numbers arm spent 2 Reads + a grep to find a
line number the line-numbered arm cited with zero follow-up calls.
Payload cost ~3-5%. Toggle off with CODEGRAPH_EXPLORE_LINENUMS=0.
2. Per-file cluster selection now ranks clusters containing a query entry
point ahead of dense declaration blocks. Density-only ranking buried
the relevant methods (perform/didCreateURLRequest/task in Alamofire's
Session.swift) under the top-of-file class header + property list.
3. Whole-file "envelope" nodes (a class/struct/etc. spanning >50% of the
file) are excluded from clustering. The Session class spans ~1,400
lines; keeping it collapsed every method into one giant cluster that
tail-trimmed down to just the class header, hiding the methods.
Net vs the 0.7.10 baseline, line numbers on: Alamofire -60%, Excalidraw
-32%, VS Code -12% per explore call.

* fix(mcp): language-neutral omission markers in explore output
The gap separator and the two tail-trim markers used C-style `//`
comments, which aren't comments in Python, Ruby, etc. Switch to plain
`... (gap) ...` / `... (trimmed) ...` so they read correctly inside any
language's fenced source block. With line numbers on, the line-number
jump already corroborates a gap.

* fix(mcp): language-neutral truncation marker in codegraph_context
Sibling to the explore marker fix: codegraph_context's code-block
truncation used a C-style `// ... truncated ...`. Switch to
`... (truncated) ...` so it reads correctly in any language's fenced
source block.

* chore(release): bump version to 0.7.11
---------
Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* release: 0.7.7 (multi-agent installer — Cursor, Codex, opencode)
* fix(installer): opencode .jsonc + AGENTS.md (0.7.8)
v0.7.7 wrote ~/.config/opencode/opencode.json, but opencode reads
opencode.jsonc by default — so the codegraph MCP entry never appeared
in any opencode session. Also installs AGENTS.md so opencode's model
reaches for codegraph_* tools instead of native Grep.
- Prefer existing .jsonc, fall back to .json, default new installs
to .jsonc.
- Surgical edits via jsonc-parser preserve user comments and
formatting across install / re-install / uninstall round-trips.
- Install AGENTS.md (global ~/.config/opencode/AGENTS.md, local
./AGENTS.md) with the shared INSTRUCTIONS_TEMPLATE — same
marker-delimited approach Codex uses.
- +9 opencode-specific tests covering filename precedence, comment
preservation, AGENTS.md install + sibling-content preservation,
uninstall reverses both files.
575/575 tests pass. Hand-verified end-to-end: opencode session calls
codegraph_node + codegraph_callers for a structural query, zero Grep
calls.

* docs: overhaul CLAUDE.md and add scripts/release.sh + Cursor rules file
Replaces the old Claude-only CLAUDE.md with a comprehensive guide covering
the full project architecture, multi-agent installer, test conventions,
NodeKind/EdgeKind reference, and release workflow. Key additions:
- Documents the layered pipeline, all module paths, and the multi-target
installer (targets/, registry.ts, AgentTarget interface).
- Adds the Cursor `--path` quirk and the "update all three surfaces" rule
when changing MCP tool guidance.
- Documents `npm run eval`, `test:eval`, and the full set of build/test
commands including single-file patterns.
- `scripts/release.sh` — idempotent bash script that tags the current
commit, pushes the tag, and creates a GitHub Release whose notes are
extracted from the matching `## [X.Y.Z]` block in CHANGELOG.md. Safe
to re-run after partial failure.
- `.cursor/rules/codegraph.mdc` — Cursor-specific agent instructions
(tool decision table, rules of thumb, index-lag warning) written by
the installer and kept in sync with server-instructions.ts and
instructions-template.ts.

The 0.7.5 tarball shipped `dist/bin/codegraph.js` without the executable
bit set, causing `zsh: permission denied: codegraph` after a fresh global
install. The build script now `chmod +x`'s the binary before packing.
Also adds CHANGELOG.md and documents the release workflow in CLAUDE.md.
* fix: add @clack/prompts transitive deps to fix npx installation
When installed via `npx`, npm's flat node_modules cache fails to
hoist ESM-only transitive dependencies from @clack/prompts → @clack/core.
This causes:
Cannot find package 'fast-wrap-ansi/index.js' imported from
@clack/core/dist/index.mjs
Adding fast-wrap-ansi, fast-string-width, and sisteransi as direct
dependencies ensures they are resolved correctly in all installation
contexts (npx, global, local).
Reproduces on Node 24 + npm 11 with `npx @colbymchenry/codegraph@0.7.3`.
* chore: bump @clack/prompts to 1.3.0 with matching transitive pins
@clack/prompts@1.3.0 shipped with major bumps to its transitive deps
(fast-wrap-ansi 0.1 → 0.2, fast-string-width 1 → 3). Promoting them
at the older pins would have caused npm to install both sets side by
side, defeating the dedup goal of this fix.

Updates Swift and Kotlin language support from basic to full in documentation and reduces explore budget thresholds to optimize performance for smaller codebases.
Replaces token reduction claims with concrete performance improvements: 94% fewer tool calls and 77% faster exploration. Reflects actual measured benefits of the code intelligence system.
Removes @xenova/transformers dependency, vector storage tables, embedding generation, and semantic search APIs. Simplifies context building to use only FTS search. Eliminates visualizer server, postinstall model download, and related CLI commands. Reduces package size and complexity while maintaining core static analysis capabilities.
Addresses potential crashes on Node.js 25+ due to V8 turboshaft WASM compiler issues. Adds runtime version check with warning to recommend Node.js 22 LTS and sets upper bound engine constraint to
Addresses Ruby methods inside modules missing owner in qualified_name by adding visitNode hook to extract module AST nodes. Methods inside modules now get Module::method qualified names with proper containment relationships. Includes ExtractorContext wiring with pushScope/popScope for language hooks and updates isInsideClassLikeNode to include module kind for nested method handling.
Replaces ASCII art banner and basic readline prompts with @clack/prompts for a modern interactive CLI. Adds animated shimmer progress bars with spinner glyphs during indexing operations. Improves installer UX with structured prompts, better error handling, and cleaner output formatting throughout all CLI commands.
Java extraction:
- Handle Java method_invocation AST (receiver.method pattern)
- Support Java extends_interfaces and super_interfaces with type_list
- Create unresolved references for Java imports for cross-file resolution
- Extract interface inheritance via extractInheritance
MCP tools:
- Aggregate callers/callees/impact across ALL matching symbols (e.g. multiple
overloads or same-named methods in different classes)
- New findAllSymbols() helper for multi-symbol lookup
Graph traversal:
- Impact analysis now traverses into container children (class → methods)
so that callers of methods appear in the impact radius of their class
Other:
- Add deleteSpecificResolvedReferences() for precise cleanup after resolution
- Add 'instance-method' to resolvedBy union type
- Version bump to 0.6.8

questions like "how does authentication work?" and see the relevant code
flow rendered as an interactive graph.
Key components:
- Visualizer HTTP server (src/visualizer/server.ts) with REST API
- Single-page frontend with Cytoscape.js graph + highlight.js code preview
- Claude CLI integration for intelligent query interpretation
- Dark theme, right-click context menus, keyboard shortcuts
- Detail panel with source code, callers, callees, hierarchy

Traverses dependency graph to identify which test files depend on changed source files. Supports stdin input for git integration, custom test file patterns, and configurable traversal depth. Useful for targeted test execution in CI/CD pipelines.
Bumps version to 0.6.2 in both package.json and lockfile to align release metadata and prevent silent install failures on fresh installs.
Relates to silent install fix
- Revert configs (MCP, hooks) to use bare `codegraph` command
- Remove all npx references from configs and messaging
- Add preuninstall script that runs on `npm uninstall -g` to clean up
MCP server, permissions, hooks, and CLAUDE.md section
- Show uninstall instructions in post-install next steps
Integrate main branch changes (WASM grammar architecture, centralized
resolution caches, SQLite adapter) with delphi-support branch. Pascal
grammar is now built as WASM and shipped in src/extraction/wasm/ for
consistency with the WASM-based grammar loading approach.

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.
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).

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.

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.

- 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
