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+.

WAL + busy_timeout were already enabled, so the issue's suggested fix was a
no-op. The real causes, addressed here:
- busy_timeout is now set first (before journal_mode) and lowered 120s -> 5s,
so open-time pragmas wait out a lock instead of hanging for two minutes.
- getCodeGraph no longer opens a second connection to the default project when
a tool passes its own projectPath (the in-process lock amplifier).
- The wasm fallback (no WAL) gets a bounded read-retry on SQLITE_BUSY.
- New: node:sqlite backend, preferred over wasm, so installs whose native
better-sqlite3 build fails land on a real-WAL backend instead of no-WAL wasm.
- codegraph status / codegraph_status now report the effective journal mode, so
a lock report is triageable (wal vs delete).
- CLI hard-blocks Node < 20 to actually enforce the engines floor.

Pre-0.8 installers wrote `codegraph mark-dirty` / `sync-if-dirty` hooks
to Claude Code's settings.json. Both subcommands were removed from the
CLI, so the Stop hook fails every turn ("unknown command
'sync-if-dirty'"). The cleanup that once removed them was lost when the
installer moved to the per-target architecture.
Add cleanupLegacyHooks(), wired into both install (upgrades self-heal)
and uninstall (so the npm preuninstall step fully reverses a legacy
install). Surgical at the command level: only codegraph's own hook
entries are dropped, so unrelated hooks sharing a matcher group or event
(e.g. GitKraken's `gk ai hook run`) survive, and a settings.json with no
legacy hooks is left byte-for-byte untouched.

Detect NestJS projects and emit `route` nodes (each linked by a `references`
edge to its handler method) across all four transport layers:
- HTTP controllers: @Controller prefix joined with
@Get/@Post/@Put/@Patch/@Delete/@Head/@Options/@All
- GraphQL resolvers: @Query/@Mutation/@Subscription
- Microservices: @MessagePattern/@EventPattern
- WebSocket gateways: @SubscribeMessage (prefixed with gateway namespace)
Detected from any @nestjs/* dependency in package.json (falls back to scanning
*.controller.ts/*.resolver.ts/*.gateway.ts). Handles class+method path joining
with empty @Controller()/@Get(), a string-aware balanced-paren arg reader so
GraphQL type thunks (@Query(() => [User])) aren't truncated, stacked decorators
(@UseGuards) when locating the handler, and disambiguates the @Query() GraphQL
method decorator from the REST @Query() param decorator (GraphQL only counts
inside @Resolver classes). Also resolves injected *Service/*Controller refs to
their classes by Nest file-naming convention.
Adds 18 framework tests; updates the README framework table and CHANGELOG.

Both git fast-paths in ExtractionOrchestrator (sync and getChangedFiles)
classified every untracked (`??`) file as "added" without checking the
index. Indexing a file doesn't make git track it, so the file stayed `??`
and was re-reported as pending and re-indexed on every run: `codegraph
status` listed it under Pending Changes forever and each `sync` re-added
it, even though its symbols were already queryable.
Merge the modified + added handling into a single hash-compared loop so
untracked files get the same treatment as tracked ones: "added" only if
missing from the index, "modified" if contents changed, skipped otherwise.
The non-git fallback path already did this and is unchanged.

`codegraph init -i` from a git super-repo containing independent nested
git repositories (not submodules) reported "No files found to index":
git ls-files reports an embedded repo only as an opaque `subdir/` entry
and never lists its files. Detect embedded repos via that trailing-slash
signal and recurse `git ls-files` into each, indexing tracked + untracked
source and honoring each repo's own .gitignore.

MCP tools failed with "CodeGraph not initialized" when a client launched
the server outside the project and sent no rootUri/workspaceFolders — the
server fell back to its own cwd, missed the project's .codegraph/, and
returned a misleading "run codegraph init" error on every call. The only
workaround was passing projectPath by hand to each tool.
When no explicit path is given, the server now asks the client for its
workspace root via the standard MCP roots/list request (gated on the
client advertising the roots capability) before falling back to cwd. This
required teaching the stdio transport to send server->client requests and
match their responses by id (previously responses were dropped as invalid).
When a project still can't be resolved, the error now names the directory
it searched and tells the user to pass projectPath or add --path to the
MCP config, instead of pointing at a re-init they don't need.

Recursive fs.watch on a WSL2 /mnt NTFS/9p mount walks the directory tree
with every readdir/stat crossing the Windows boundary, stalling the event
loop long enough to blow past opencode's 30s MCP handshake timeout so the
tools never appear. This is the file-watcher half of the #172 fix, which
moved the DB/WASM open off the handshake but left the watcher on the
critical path.
- Add watchDisabledReason() policy: CODEGRAPH_NO_WATCH (off) >
CODEGRAPH_FORCE_WATCH (force on) > WSL2 + /mnt auto-detect (off).
FileWatcher.start() and the MCP server both honor it; the server now
logs why watching is off and how to refresh.
- Add `codegraph serve --mcp --no-watch`.
- When watching is off, init/install offer git sync hooks (post-commit,
post-merge, post-checkout) that run `codegraph sync` in the background,
or fall back to manual sync; either way the user is told the index
stays frozen until re-synced. uninit removes the hooks.
- Tests: watch-policy + git-hooks (idempotency, user-content preservation,
core.hooksPath).

Project-local installs wrote the MCP server to ./.claude.json, which Claude Code never reads — project-scoped servers must live in .mcp.json. The codegraph tools silently never loaded until users renamed the file by hand. Local installs now write ./.mcp.json and migrate any stale ./.claude.json entry on install and uninstall (siblings preserved). Global installs (~/.claude.json, user scope) were already correct.

* 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

truncation used a C-style `// ... truncated ...`. Switch to
`... (truncated) ...` so it reads correctly in any language's fenced
source block.

Output is now scaled to indexed file count. Small projects (<500 files)
cap at ~18KB and skip the "Additional relevant files" / completeness /
explore-budget reminders that earn their keep on larger codebases; medium
(<5,000) caps at ~28KB; large (<15,000) keeps the historical ~35KB; very
large goes up to ~38KB.
A per-file char cap also prevents a single file with many adjacent
symbols from collapsing into one whole-file dump (the pathological
Alamofire `Session.swift` case reported in #185), and a per-file symbol-
list cap stops the `#### path — sym(kind), ...` header from leaking
multi-KB lists when many adjacent symbols cluster together.
Measured against the README's benchmark repos: Alamofire (~100 files)
~62% smaller per call, Excalidraw (~600 files) ~35%, VS Code (~10k
files) ~14%. Agent-trust floor preserved — Relationships, scored cluster
selection, and structured-source output are all retained.

`codegraph_callees stage_apply::run` (and `_node`, `_impact`, ...)
returned "not found" against a repo with 7-9 sibling Rust modules,
each exporting `pub async fn run`. Two underlying issues:
1. The FTS5 query builder stripped `:` as a special char without
splitting on `::`, so `stage_apply::run` collapsed to the literal
`stage_applyrun` which matches nothing. Treat `::` as whitespace
before the strip step so both halves become FTS tokens.
2. `matchesSymbol` only understood `Parent.child` qualifiers and
relied on `qualifiedName` carrying the module path. Rust file-
level functions don't have their module name in `qualifiedName`
(it's encoded in the file path instead), so even dot-style
lookups failed. Accept `::`, `.`, `/` as separators; multi-level
forms compose; Rust `crate::`/`super::`/`self::` prefixes get
stripped before path matching. Fall back to file-path containment
when the qualified-name suffix doesn't match — `stage_apply::run`
matches a `run` in any file whose path has a `stage_apply` segment.
Also tightens the no-match branch: qualified lookups no longer fall
through to a fuzzy text match. `stage_apply::nonexistent_fn` returns
`null` instead of silently resolving to an unrelated `rollback` in
the same file.

The shimmer progress renderer writes from a worker thread via
`fs.writeSync(1, ...)` to keep the animation smooth while the main
thread is busy in SQLite. That path bypasses Node's TTY-aware
UTF-8->codepage conversion on Windows, so glyphs like `|`/`<>`/`-`
were emitted as raw UTF-8 bytes and reinterpreted by the console's
OEM codepage (CP437, CP936, ...), producing strings like
`鋍?[0m 鉒?[0m Scanning files 鈥?N found`.
Add `src/ui/glyphs.ts` with `supportsUnicode()` detection plus
matched Unicode + ASCII glyph sets, and route all CLI/shimmer
output through `getGlyphs()`. Defaults: ASCII on Windows and on
Linux kernel consoles (`TERM=linux`), Unicode everywhere else.
`CODEGRAPH_UNICODE=1` and `CODEGRAPH_ASCII=1` are escape hatches.

The MCP `initialize` handler was awaiting `tryInitializeDefault` —
which opens the SQLite DB and runs `await initGrammars()` (tree-sitter
WASM bootstrap) — before sending the JSON-RPC response. On slow
filesystems (Docker Desktop VirtioFS on macOS, WSL2) this could exceed
Claude Code's ~30s handshake timeout, leaving the codegraph child
process alive and unresponsive with no tools visible in the client.
Send the response first; defer the open to a tracked background
promise. The lazy retry path used by `tools/list` and `tools/call`
now awaits that promise instead of racing it with `openSync`, so we
never double-open the SQLite file.
Adds a subprocess-based regression test that asserts the JSON-RPC
response arrives on stdout before `startWatching()` logs to stderr.
This ordering check catches the regression on any filesystem, not
just slow ones where the timing matters in practice.

* 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.

* feat(installer): multi-target — Claude Code, Cursor, Codex CLI, opencode
Closes the Claude-locked installer behind issue #137. The runtime MCP
server was already agent-agnostic (stdio); only the installer was
locked. After this refactor, `codegraph install` can write per-agent
MCP config + instructions for any combination of supported agents.
## What ships
Four agent targets, each implementing the new `AgentTarget` interface:
- **Claude Code** — `~/.claude.json`, `~/.claude/settings.json`,
`~/.claude/CLAUDE.md` (or local equivalents). Behavior preserved
from the original installer; existing installs upgrade in place.
- **Cursor** — `~/.cursor/mcp.json` (g) or `./.cursor/mcp.json` (l)
+ project-local `./.cursor/rules/codegraph.mdc`.
- **Codex CLI** — `~/.codex/config.toml` with `[mcp_servers.codegraph]`
+ `~/.codex/AGENTS.md`. Global only. Hand-rolled TOML serializer
scoped to the table we own — siblings + array-of-tables preserved.
- **opencode** — `~/.config/opencode/opencode.json` (XDG) or
`./opencode.json`.
Adding a 5th agent is a new file in `src/installer/targets/` plus
one entry in `registry.ts`.
## CLI changes
```
codegraph install # interactive multi-select
codegraph install --yes # auto-detect, install global
codegraph install --target=cursor,claude --yes # explicit list
codegraph install --target=auto --location=local # detected, project-local
codegraph install --target=none # skip agent writes entirely
codegraph install --print-config codex # dump snippet, no writes
```
## Backwards compat
Every export from the old `config-writer.ts` (`writeMcpConfig`,
`writePermissions`, `writeClaudeMd`, `hasMcpConfig`, `hasPermissions`,
`hasClaudeMdSection`) is preserved as a `@deprecated` shim that
delegates to per-file helpers in `targets/claude.ts`. Existing Claude
users see byte-identical on-disk layout — `detect()` reports
`alreadyConfigured: true`, re-running is a no-op.
## Tests
+47 new tests in `__tests__/installer-targets.test.ts`:
- Parameterized contract test across all 4 targets × supported
locations (install → unchanged on re-run, sibling preservation,
uninstall reverses install, printConfig writes nothing).
- Codex partial-state recovery, locked-block contract for the
codegraph table, full TOML serializer suite.
- Registry: getTarget, resolveTargetFlag (auto/all/none/csv).
`__tests__/installer.test.ts` relaxed one assertion: the new code
returns `unchanged` for byte-identical re-runs instead of `updated`;
the surrounding-custom-content contract is unchanged.
## Uninstall behavior change
`bin/uninstall.ts` now loops `ALL_TARGETS.uninstall('global')` on
`npm uninstall -g`. A user who manually configured
`~/.codex/config.toml` with our block will have only that block
removed on package uninstall — we only touch the dotted-key table
we own.
Based on andreinknv/codegraph@c5165e4. Issue #137.

* chore(scripts): add local-install.sh for hands-on branch testing

`codegraph` binary. `--undo` unlinks and reinstalls the published
version. Mirrors the style of scripts/release.sh.

* feat(installer): move agent picker to the first prompt
Reorders runInstallerWithOptions so the multi-select for agents
(Claude / Cursor / Codex / opencode) is step 1 — before the
global-npm-install confirm and before the location prompt. Bare
`npx @colbymchenry/codegraph` now opens with "Which agents should
CodeGraph configure?", which is the answer most users want first.
Side effects of the reorder:
- Early exit if zero targets selected — skips global-install and
location prompts entirely, exits with "nothing to do."
- Multiselect labels drop the per-location "will skip" hint (location
isn't known yet) and replace it with a static "global only" badge
for targets like Codex that have no project-local config concept.
- If every selected target is global-only, the location prompt is
skipped and global is forced (no point asking).
- Detection probes the user-provided location if known via flag,
else 'global' as the most common default — labels are a hint
about what's installed locally, not load-bearing.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(installer): disambiguate "global" wording in install prompts
Two prompts both said "global" but meant different things — users
read them as duplicates. Renamed for clarity:
- Step 2 (npm install -g): "Install codegraph globally?" →
"Install the codegraph CLI on your PATH? (Required so agents can
launch the MCP server)". Spinner messages match.
- Step 3 (config location): "Where would you like to install?" with
"Global"/"Local" → "Apply agent configs to all your projects, or
just this one?" with "All projects" (~/.claude, ~/.cursor, etc.)
/ "Just this project" (./.claude, ./.cursor, etc.).
- All-global-only fallback: "Using global install" → "Writing
user-wide configs (selected agents have no project-local config)."
Underlying `Location` values ('global' / 'local') unchanged; only
the UI strings shift, so no test or flag breakage.

* fix(installer/cursor): inject --path so workspace-aware queries work
Cursor launches MCP-server subprocesses with cwd != workspace root,
AND does not pass rootUri or workspaceFolders in the MCP initialize
call. The codegraph MCP server's process.cwd() fallback misses the
workspace's .codegraph/ and reports "not initialized" on every tool
call. Codex and Claude don't have this issue (Codex launches with
cwd=workspace, Claude passes rootUri).
Fix: inject `--path` into the args we write for Cursor.
- local install (./.cursor/mcp.json): hardcode the absolute project
path — known at install time.
- global install (~/.cursor/mcp.json): use `${workspaceFolder}` so
Cursor expands it per-workspace. One global config now drives
every project the user opens, without per-project re-install.
No test breakage — the parameterized contract tests check
idempotency / sibling preservation, not the exact args content.
File-header comment documents the rationale so the next person
doesn't strip the arg as boilerplate.

* feat(init): auto-wire project-local agent surfaces
Closes the global-Cursor UX gap: `~/.cursor/mcp.json` registers the
MCP server, but Cursor's agent only learns to *prefer* codegraph
over native grep when it sees `.cursor/rules/codegraph.mdc` — a
project-local file that global install can't write. Previously the
user had to re-run `codegraph install --target=cursor --location=local`
for every new project. Now `codegraph init` does it automatically.
## What changed
- New optional `AgentTarget.wireProjectSurfaces()` returning a
WriteResult of project-local files to drop. Most targets omit
it (their global config is complete). Cursor implements it to
write the rules file.
- New `wireProjectSurfacesForGlobalAgents()` orchestrator in
installer/index.ts — iterates ALL_TARGETS, detects which are
configured globally, calls their wireProjectSurfaces, returns
what was written.
- `codegraph init` calls the orchestrator in both branches:
- Fresh init: write surfaces after CodeGraph.init succeeds.
- Already-initialized re-init: write surfaces too, so re-running
`init` is the documented recovery path for a project missing
its rules file.
## Steady-state UX
1. Once, ever: `codegraph install` (writes global agent configs)
2. Per project: `codegraph init -i` (builds the index + auto-wires
project-local agent surfaces — currently Cursor's rules file)
No new tests — wireProjectSurfaces delegates to writeRulesEntry,
which is already covered by the parameterized contract tests.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(installer): agent-agnostic instructions template
The old template was inherited from the Claude-only era and
prescribed "ALWAYS spawn an Explore agent" — a Claude Code-specific
concept (subagents via the Task tool). When Cursor's agent read
this it had no Explore agent to spawn, got confused, and fell back
to native grep/read even for structural queries the codegraph MCP
tools answer in one call.
This rewrite:
- Frames each tool by the question it answers (search vs callers
vs impact vs context vs explore vs node vs files vs status).
- Tells the agent explicitly to TRUST codegraph results and not
re-verify them with grep — the over-grep-after-codegraph
behavior was the main symptom we saw on Cursor.
- Reframes "spawn Explore agent" as an OPTIONAL pattern for
harnesses that support parallel subagents — Claude Code still
gets the hint, Cursor / Codex / opencode just skip it.
- Trims the "if not initialized" section to one prescriptive line.
Same marker delimiters (`<!-- CODEGRAPH_START/END -->`) so existing
installs upgrade in place via the marker-based section swap. No
test changes needed — the parameterized contract tests check
marker placement + sibling preservation, not the literal body.
Effective surfaces: ~/.claude/CLAUDE.md (Claude), .cursor/rules/
codegraph.mdc (Cursor, project-local), ~/.codex/AGENTS.md (Codex).
Users get the new copy by re-running `codegraph install` for
global writes, or `codegraph init` for Cursor's project rules.

* docs(readme): reflect multi-agent support at the top + accurate flow
- Tagline now reads "Supercharge Claude Code, Cursor & Codex" instead
of Claude-only — multi-agent support is what the PR is about, the
README should say so above the fold.
- New badge row (Claude Code / Cursor / Codex CLI / opencode) in the
same shields.io style as the OS row.
- Install-flow bullets reordered to match the actual prompt order
(agent picker first, then PATH install, then location).
- `codegraph init -i` step now mentions that init wires up
project-local agent surfaces (Cursor rules file etc.) so global
install works in every project without a re-run.
- Agent-agnostic phrasing in the closing line ("your agent" not
"Claude Code").
Headline-level brand decision left intentionally in this PR — the
existing Claude-only positioning predates multi-agent support.

* feat(rust): expand cargo workspace member globs and trust workspace hits
- Parse glob entries in `[workspace].members` (e.g. `crates/*`,
`helix-*`) via picomatch against a new optional
`ResolutionContext.listDirectories` so workspaces that don't
enumerate every member are covered. Implementation walks the
static-prefix subtree with a depth cap and skips `target`,
`node_modules`, `.git`, etc.
- Bump Pattern 4's confidence to 0.95 when the workspace map
produces a hit. The cargo manifest gives an unambiguous
crate-name -> crate-root mapping, so workspace-driven module
resolution should beat name-matcher's self-file matches
(otherwise every file with `use foo::...` self-resolves at 0.7
and the cross-crate edge never materializes).
- Validated against astral-sh/uv (`members = ["crates/*"]`,
67 crates, 567 .rs files): 1,969 cross-crate `imports` edges
reaching 60 distinct member lib.rs files, up from 0.

`git ls-files -co --exclude-standard` only sees the submodule pointer in
the main repo's index, so projects using submodules indexed 0 files. Now
the tracked list runs with `-c --recurse-submodules` so submodule
contents are included; untracked files are gathered with a separate
`-o --exclude-standard` call (the two flags can't be combined — git only
supports --recurse-submodules with --cached/--stage).
Fixes#147.

The Node 25.x V8 turboshaft WASM JIT Zone allocator bug
(https://github.com/colbymchenry/codegraph/issues/81) reliably crashes
CodeGraph mid-indexing with `Fatal process out of memory: Zone` when
tree-sitter grammars get JIT-compiled. We already had:
- `engines: "node": ">=18.0.0 <25.0.0"` in package.json
- Lazy grammar loading (#61)
- A startup `console.warn` when Node 25+ is detected
But the recurring duplicates (#54, #81, #140, plus comments from
multiple unique users) show those defenses aren't enough:
- npm `engines` is a soft warning by default, so `npm install -g`
doesn't block.
- The startup `console.warn` is a single yellow line that scrolls
off-screen before the OOM 30 seconds later, so users connect the
crash to "CodeGraph is broken" rather than "I'm on the wrong Node
version" and file a fresh issue.
This patch turns the soft warning into a hard exit. On Node 25+ we
print a bordered banner that names the V8 root cause, embeds the
detected version, gives Node 22 LTS install commands (nvm + Homebrew),
and links to #81 — then exit(1) BEFORE any tree-sitter import
triggers WASM JIT. The previous behaviour is preserved behind
`CODEGRAPH_ALLOW_UNSAFE_NODE=1` for anyone who patched V8 themselves
or wants to test a future Node 25 fix.
The banner builder is extracted to `src/bin/node-version-check.ts` so
the test can import it without triggering CLI bootstrap. Five unit
tests pin the version interpolation, root-cause explanation, recovery
commands (nvm + brew), override env var, and #81 link — these are
load-bearing and shouldn't get edited away silently.
Suite: 509 → 514, all passing. Verified both paths manually by
flipping the threshold to 22 in dist and running on Node 22.20.0:
without the env var the CLI prints the banner and exits 1; with
`CODEGRAPH_ALLOW_UNSAFE_NODE=1` it prints the banner and continues.

Closes the visibility gap behind issues #138 (WASM-on-macOS) and #139
(MCP "database is locked"). `better-sqlite3` is in optionalDependencies,
so when the native build fails npm install still succeeds and the
runtime silently falls back to node-sqlite3-wasm — 5-10x slower and
without WAL, so writers block readers (which is what makes the MCP
server appear to "lock the DB" in #139). The only existing signal was
a one-line `console.warn` to stderr that MCP transports typically
swallow.
This patch does NOT change install behavior — better-sqlite3 stays in
optionalDependencies so cross-platform installs keep working. It just
makes the substitution observable + recoverable.
## Visibility (4 surfaces)
- CLI `codegraph status`: new `Backend:` line under Index Statistics.
`native` rendered green; `wasm` rendered yellow with an inline
`npm rebuild better-sqlite3` nudge. Also exposed in `--json` as
`backend: 'native' | 'wasm'`.
- MCP `codegraph_status`: new `**Backend:**` line. Native form reads
`native (better-sqlite3)`; wasm form prepends a warning glyph and
includes the full fix recipe.
- Stderr banner on fallback (`buildWasmFallbackBanner`): replaces the
bare one-line `console.warn` with a multi-line bordered banner
covering macOS + Linux fix steps and optionally appending the
native load error.
- README troubleshooting: new "Indexing is slow / MCP database is
locked / WASM fallback active" entry that walks users to the
`Backend:` line and the fix.
## Per-instance backend tracking
`createDatabase` previously set a module-level `activeBackend` global.
MCP can open multiple project DBs in one process via the
`getCodeGraph()` cache, so the global would race / overwrite. Refactor:
`createDatabase` now returns `{db, backend}`, `DatabaseConnection`
carries `private backend` and exposes `getBackend()`, and
`CodeGraph.getBackend()` is the public surface. The CLI and MCP both
call `cg.getBackend()`.
## What this does NOT fix
The root cause of users landing on WASM is environment-specific (Mac
without Xcode CLT, Node version mismatch, etc.) and not fixable in
code without changing the optionalDependencies design. The README
entry tells users what to run; `Backend: native` after rebuild is the
confirmation signal.
## Tests
New `__tests__/sqlite-backend.test.ts` (6 tests) pins the banner
recipe content (so future edits can't strip the recovery commands),
the `WASM_FALLBACK_FIX_RECIPE` constant, and per-instance
`DatabaseConnection.getBackend()` / `CodeGraph.getBackend()` reporting.
Suite: 503 → 509, all passing.

at 6d0e7a2 + 69f7001) framed the visibility approach.

Replaces comment characters and string-literal contents with spaces (not
removal) so source offsets stay valid for downstream regex match index ->
line number conversion. Handles Python triple-quoted docstrings, Ruby
=begin/=end, Rust nested block comments, and the standard //, #, /* */
forms across the supported languages.
This is consumed by framework extract() methods in a follow-up commit so
that commented-out / docstring routing examples don't surface as phantom
route nodes in the graph.
* feat(frameworks): strip comments before regex extraction (prevents phantom routes)
Pipes the per-language stripCommentsForRegex helper into every framework
extract() that scans raw source: django/flask/fastapi (python.ts),
express, laravel, rails, spring, go, rust, aspnet, vapor, plus
swiftui/uikit struct extraction in swift.ts.
Without this, examples like:
# path('/admin/', AdminPanel.as_view())
""" path('/users/', UserListView.as_view()) """
urlpatterns = [path('/real/', RealView.as_view())]
produced 3 phantom route nodes. Now only the real one is extracted.
Each framework gets a regression test in __tests__/frameworks.test.ts
asserting that line-, block-, docstring- and (where relevant)
heredoc-style commented-out routes do not surface as nodes.

Both narrow indexes are fully covered by the existing (source, kind)
and (target, kind) composites via SQLite's left-prefix scan, so
they're dead weight on every write. Empirical measurements (from the
spike script in PR #122 on a 50K-node / 250K-edge synthetic DB):
- DB size: 34.7 MB → 27.0 MB (-22.2%)
- Bulk insert (250K edges): 590ms → 431ms (1.37× faster)
- source/target lookup latency: no regression
Adds migration v4 to drop both on existing databases; fresh-DB schema
no longer creates them.

Two correctness bugs in the core extraction pipeline, surfaced by an
adversarial stress corpus (5k synthetic export-const declarations
plus a deliberate 8MB single-line file):
1) Every `export const X = ...` produced TWO nodes for the same
symbol — one kind:'variable' from extractExportedVariables, plus
one kind:'constant' from extractVariable (called when the walker
descended into the export_statement child). Stress test showed
100% duplication across 5,003 export-const declarations. The
dedicated extractVariable dispatch is the correct one — it picks
kind from isConst, captures the initializer signature, and walks
type annotations; the export-statement helper was redundant
because the language extractors' isExported predicate already
walks parent chains. Remove the export_statement branch from the
dispatch (children are descended into normally) and drop the
private helper.
2) The bulk indexAll path read each file's stats but never compared
stats.size against config.maxFileSize. Vendored generated files
(multi-MB headers, minified bundles, etc.) were indexed regardless
of the user's size cap. The single-file extractFile path enforced
it; only the bulk path was missing the check. Mirror the
single-file behaviour: emit a 'size_exceeded' warning, count the
file as skipped, advance progress, and continue.
On the stress workspace (5,005 synthetic files; 50,000 fns in one
3MB file; 8MB single-line file; 5,000 export-const declarations):
before: 65,014 nodes (100% var/const duplication, every >1MB file
indexed despite maxFileSize=1MB)
after: 10,008 nodes (0 duplicates, large files correctly skipped
with size_exceeded warnings)
Tests calibrated to the duplicate behavior were updated to look for
kind:'constant' on `export const`, which is the correct kind. Full
suite: 380 passed (was 374 passed, 6 failed before this fix).
* feat(resolution): tsconfig path aliases + re-export chain following
Two related correctness improvements that unlock accurate import
resolution on modern JS/TS codebases.
1) tsconfig/jsconfig path aliases.
The resolver previously had a hard-coded list of common aliases
(@/, ~/, src/, app/) and ignored any project-defined paths from
tsconfig.json compilerOptions.paths — which means every import
through @components/Foo, @lib/utils, etc. on Vite/Next/Nuxt/Nest
projects silently failed to resolve. Adds src/resolution/path-
aliases.ts that reads tsconfig.json (and falls back to jsconfig.json),
honours baseUrl, supports the * wildcard, and respects the priority
order of multiple replacement targets per alias. JSONC tolerant
(strips comments + trailing commas, common in the wild). The new
ResolutionContext.getProjectAliases() lazily loads + caches the
result; resolveAliasedImport consults it before the legacy fallback
list.
Verified live on a synthetic project with @utils/* and @lib custom
aliases: both resolved to the correct files and produced edges,
unresolved_refs empty.
2) Re-export chain following.
`import { Foo } from './barrel'` where barrel.ts only re-exports
(`export { Foo } from './real'` or `export * from './real'`) used
to fail because the resolver only looked for declarations IN the
resolved file — it never followed the export chain to the actual
definition. Adds extractReExports() (named + wildcard + as-rename
forms), a per-file getReExports() context method, and a recursive
findExportedSymbol() helper with depth cap (8) and visited-set
cycle protection. resolveViaImport now uses it whenever the symbol
isn't directly declared in the imported file.
Verified live on a synthetic 3-hop chain (main → all.ts wildcard →
index.ts named → auth.ts declaration): signIn resolved correctly,
unresolved_refs empty.
Full test suite: 380 passed, 0 failed.
* fix(resolution): address reviewer findings — isExternalImport bypass, JSONC strings, comment stripping, optional context method
Five fixes from independent semantic review:
- isExternalImport now consults context.getProjectAliases() before
the bare-specifier heuristic. Without this, custom prefixes like
'@components/*' from tsconfig.paths were classified as npm and
resolveAliasedImport never even ran. Adds a context parameter
(optional, for backward compat with mock contexts).
- stripJsonc rewritten as a string-aware state machine. The previous
regex-only version corrupted any URL embedded in a JSON string
value ('https://cdn.example.com' lost everything after '//').
- extractReExports now strips JS line+block comments from content
before applying the regex, so a commented-out 'export { x } from
...' no longer creates a phantom re-export edge. New
stripJsComments helper preserves string literals (single, double,
template) so '//' inside a string stays intact.
- ResolutionContext.getProjectAliases() made optional so existing
mock contexts in __tests__/resolution.test.ts (which TypeScript
doesn't type-check because tsconfig excludes __tests__) don't
throw at runtime when resolveAliasedImport hits them. Caller
uses ?.
- Two new integration tests in __tests__/resolution.test.ts:
* Path-alias resolution with name-collision: two pickMe() in
different dirs, only the @utils-aliased one should be the
call target. Asserts via getCallers on each candidate node.
* No-tsconfig fallback: relative import still produces the call
edge.
Full test suite: 832 passed (was 380; the increase is from the
biomarkers + LLM hooks that ship via parent branches).
* fix(resolution): allow re-export rename chains past the pre-filter
The fast pre-filter in resolveOne() bails when no symbol with the
reference name exists project-wide, which is incompatible with the
new chain-following code: a renamed re-export (`import { login }
from './barrel'` where the barrel does `export { signIn as login }
from './auth'`) intentionally calls a name that has no project-wide
declaration. The chain finds the renamed upstream symbol — but only
if resolution is allowed to run.
Add an import-mapping escape so the pre-filter only bails when the
ref also doesn't match any local import. Adds two tests covering the
3-hop wildcard chain and the named-rename branch.

* feat(search): field-qualified queries (kind:/lang:/path:/name:) + fuzzy typo fallback
Two UX improvements that turn a free-text search into something a
real user can drive precisely.
1) Field-qualified queries.
A new query parser (src/search/query-parser.ts) splits the raw query
into structured filters and a free-text remainder:
kind:function name:auth path:src/api authenticate
becomes
{ kinds: ['function'], nameFilters: ['auth'],
pathFilters: ['src/api'], text: 'authenticate' }
Filters compose with the SearchOptions arg (intersection). Unknown
prefixes pass through as plain text so `query "TODO:"` keeps working.
Quoted values (`path:"my dir"`) handle whitespace. When the user
specifies only filters with no text, the search uses a filter-only
candidate scan instead of bailing out.
Recognised today:
kind: any NodeKind value
lang: any Language value (alias: language:)
path: case-insensitive substring of file_path
name: case-insensitive substring of node.name
2) Fuzzy fallback.
When BOTH FTS and LIKE return nothing AND the text is at least 3
chars, the resolver scans the distinct-name set with a bounded
Damerau-Levenshtein-style edit distance (≤2 for ≥5 chars, ≤1 for
4-char queries, off for shorter). Bounded edit-distance early-exits
once the row min exceeds maxDist, so this stays O(distinct-names *
avg-name-length) with a very low constant.
Verified live against ollama/ollama@v0.22.0:
query "kind:function auth" → only function-kind hits
query "lang:go path:server route" → Go files under server/
query "getUssr" (typo) → finds getUser, SetUser
query "confg" (typo) → finds Config
Full test suite: 380 passed.
* fix(search): address reviewer findings — tokenizer mid-token quotes, fuzzy fan-out cap, larger filter-only over-fetch, unit tests
Five fixes from independent review:
- parseQuery tokenizer: quotes that appear MID-token (path:"my dir/
file") were not being recognised — only quotes at the start of a
token were treated as quoted spans. The fixture path:"my dir"
parsed as ['path:"my', 'dir"'] instead of ['path:"my dir"'].
Tokeniser is now a single state machine that scans into a token
until whitespace OR a quote, and recognises quotes anywhere within
the token (skips to the matching close quote).
- searchNodesFuzzy: cap the per-name follow-up SQL queries at
Math.max(limit*2, 50) AFTER edit-distance filtering. Without
this, a project with many similar names (getUser1, getUser2...)
could fan out far beyond limit queries before the inner-loop
break kicks in.
- searchAllByFilters (filter-only no-text path): bumped over-fetch
multiplier from 2× to 5× so a selective post-filter (e.g.
path:src/very/specific/file.ts) doesn't return fewer than limit
results despite the DB having matches.
- 23 new unit tests in __tests__/search-query-parser.test.ts:
parseQuery covers known-field filter, lang/language alias,
multiple kind: ORs, quoted spans (incl. mid-token), URL
passthrough, empty-value passthrough, unknown prefix passthrough,
unknown value passthrough, all-filters-no-text, empty input,
20k-char input. boundedEditDistance covers identity, single
insertion/deletion/substitution, length-difference shortcut,
empty inputs, case-sensitivity, early-exit correctness.
Full test suite: 853 passed (up from 830).
* refactor(search): derive parser kind/lang sets from types.ts as const
Convert NodeKind and Language to runtime-iterable as const arrays
(NODE_KINDS, LANGUAGES) so the query parser imports the canonical
list instead of duplicating it. Also fix the path: JSDoc to say
substring (matches the .includes() impl).

* feat(extraction): instantiates + decorates graph edges
Two new structural edges that fill gaps in the call graph for
modern JS/TS / Java / C# / Python / Kotlin codebases.
1) `instantiates` edges from `new Foo(...)`:
The bulk-extraction and visitFunctionBody dispatchers only
recognised `call_expression`; `new_expression` (and the equivalent
`object_creation_expression` / `instance_creation_expression` in
other grammars) was silently ignored. Adds INSTANTIATION_KINDS,
extractInstantiation(), and dispatch from BOTH the top-level
visitNode and the per-function-body walker. Children are still
descended so nested calls inside constructor args (`new Foo(bar())`)
get their own `calls` refs.
Output: a `bootstrap` function that does `new UserService(); new
UserController(svc)` now produces two `instantiates` edges to those
class nodes — previously zero edges.
2) `decorates` edges from `@Decorator` annotations:
Tree-sitter places decorator nodes BEFORE the symbol they apply to
in the AST, so the original walk-time dispatch saw the wrong
nodeStack head (file/class instead of class/method). Replaced with
extractDecoratorsFor(declNode, decoratedId) that runs from inside
extractClass / extractFunction / extractMethod after the symbol's
node id is known.
Looks for decorator nodes in two places:
- Direct named children of the declaration (method/property style)
- Preceding siblings in the parent (TypeScript class style:
@Foo class X {} parses as parent { decorator, class_decl })
Sibling check uses startIndex comparison rather than reference
identity — tree-sitter web bindings return fresh JS wrappers from
parent/namedChild navigation, so `===` is unreliable. Took a debug
session to spot this; flagging in the comment so the next reader
doesn't re-introduce the bug.
Output: a `@Controller` class decorator + `@Get` method decorator
on a NestJS-style controller now produce two `decorates` edges
(class→Controller, method→Get) with the correct source nodes.
Verified live on a synthetic NestJS-shape fixture; all 380
existing tests pass.
* fix(extraction): address reviewer findings — decorator boundary, generic constructors, property/field decorators, marker_annotation, tests
Five fixes from independent semantic review:
- extractDecoratorsFor sibling walk now iterates BACKWARD from the
declaration and stops at the first non-decorator/annotation
separator. Previous version walked forward up to declStart and
consumed every decorator-typed sibling — so two adjacent
decorated classes (`@A class Foo {} @B class Bar {}`) had `@A`
spuriously attributed to `Bar`.
- extractInstantiation strips the type-argument suffix from the
constructor field text. `new Map<K, V>()` was producing
referenceName 'Map<K, V>' (the constructor field is a generic_type
node) and resolution always failed.
- extractProperty and extractField now call extractDecoratorsFor
after their createNode calls. NestJS-style `@Inject() private
svc: Foo` and Java field annotations were being silently dropped.
- consider() in extractDecoratorsFor recognises 'marker_annotation'
in addition to 'decorator'/'annotation'. Java's tree-sitter grammar
emits marker_annotation for arg-less annotations like @Override
and @Deprecated; without this every Java marker annotation was
silently skipped.
- 6 new extraction tests covering: instantiates ref for new Foo(),
generic-type stripping (`new Container<string>()` -> 'Container'),
qualified-new keeps trailing identifier (`new ns.Foo()` -> 'Foo'),
decorates ref for @Foo class X {}, regression for adjacent
decorated classes (each gets its OWN decorator), decorates ref
for @Foo method().
Full test suite: 386 passed (was 380, +6 new extraction tests).
* feat(resolution): kind-aware scoring + Python instantiation promotion
Two follow-ups to the new instantiates/decorates ref kinds, surfaced
during review:
1) name-matcher previously only had a kind bonus for `calls`
(preferring function/method). When a class and a function share a
name across modules, an `instantiates` ref would tie or pick the
wrong candidate. Adds:
- `instantiates` → +25 for class/struct/interface
- `decorates` → +25 for function/method, +15 for class
(Python class decorators, Java annotation interfaces)
2) Python (and Ruby) have no `new` keyword — `Foo()` is the standard
instantiation syntax, indistinguishable from a function call at
extraction time. Resolution can tell the difference once the
target is known: when a `calls` ref resolves to a class/struct,
promote it to `instantiates`. Mirrors the existing extends→
implements promotion in createEdges.
Verified: 386 → 389 passing (+3 tests covering the kind biases and
the Python promotion).

Addresses the need for automatic graph synchronization on file changes. Implements FileWatcher using native OS file events (FSEvents/inotify/ReadDirectoryChangesW) with 2-second debouncing to prevent thrashing on rapid saves. Filters changes against include/exclude patterns and ignores .codegraph directory modifications. Integrates with CodeGraph API (watch/unwatch/isWatching methods) and MCP server for automatic activation. Updates documentation to reflect shift from semantic to full-text search and removal of manual hook installation requirements.
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 two tree-sitter misparse patterns: (1) fun interfaces with @Throws annotations parse as function_declaration > ERROR instead of user_type, (2) parent interface bodies become ERROR nodes when containing nested fun interfaces, causing methods to be skipped. Updates isFunInterfaceNode to check ERROR-nested user_type children and resolveBody to prefer ERROR bodies starting with `{`.
Addresses Kotlin interfaces/enums extracted as classes, zero function calls, and missing `fun interface` declarations. Adds classifyClassNode to distinguish interfaces/enums from classes, resolveBody hook for non-field grammar, navigation_expression call handling, getReceiverType for extension functions, and visitNode hook to detect `fun interface` misparse patterns from tree-sitter-kotlin's lack of Kotlin 1.4+ syntax support. Verified against Koin and LeakCanary codebases.
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.
Addresses PHP's base_clause syntax for class inheritance (extends) and implements clause for interface implementation. Adds trait_declaration support and separates property_declaration into fieldTypes. Improves PHP method call extraction by handling member_call_expression and scoped_call_expression with proper receiver name processing, including $ prefix stripping and self/this/parent/static receiver filtering.
Addresses Rust's impl block syntax where trait implementations (`impl Trait for Type`) and trait supertraits (`trait Sub: Super`) create inheritance relationships. Adds getReceiverType to extract method receiver types from impl blocks, enabling proper method-to-struct relationships and qualified name resolution. Verified against Deno codebase and moved from "Needs Verification" to completed language support.
Addresses Swift's inheritance_specifier syntax where type relationships are specified after colons (e.g. `class UploadRequest: DataRequest, Sendable`). Extracts user_type > type_identifier children from inheritance_specifier nodes as 'extends' references to properly model Swift's inheritance, protocol conformance, and struct conformance patterns in the code graph.
Addresses cases where multi-word queries like "search execution from request to shard" return generic single-term matches instead of highly relevant classes matching multiple terms. Applies co-occurrence boosting before truncation to prioritize nodes matching 2+ query terms, adds compound term matching to catch classes like "SearchShardsRequest" that contain multiple query terms at any position, and widens per-term accumulation pools to prevent relevant multi-term matches from being filtered out early.
Introduces automated testing infrastructure to measure CodeGraph performance across searchNodes and findRelevantContext APIs. Includes recall/MRR scoring metrics, predefined test cases for symbol lookup and context exploration, and JSON report generation. Enhances context building with acronym extraction, definition prefix matching, and improved FTS filtering to exclude imports by default.
Adds expression index on lower(name) for memory-efficient case-insensitive searches, replacing in-memory caches that caused OOM on large codebases. Includes batched reference resolution, enhanced error reporting with detailed breakdown by error type, and improved CLI progress display for scanning phases.
Adds type annotation parsing to create references edges for parameter types, return types, and variable type annotations in TypeScript and other typed languages. Expands symbol extraction from queries to capture lowercase identifiers and filters out more common English words. Removes obsolete search utility tests.
Testing showed semantic search produces significantly better results for
natural language queries that Claude writes. FTS alone often ranks
properties above their parent classes and misses conceptual matches.
Embeddings are now always on — the vector manager is created eagerly,
with model download and embedding generation still happening lazily.

Name matching was creating false `calls` edges between unrelated modules
in monorepos because `findBestMatch()` had no concept of directory
proximity — functions with common names (e.g. `navigate`) in different
apps scored identically and resolved to whichever came first.
Adds path proximity scoring (shared directory segments) so same-module
candidates strongly win over cross-boundary ones, and lowers confidence
for distant matches so import-based resolution takes precedence.
Closes#67

Fixes#54 — `codegraph init -i` crashes with "Fatal process out of memory: Zone"
on large codebases because all 16 tree-sitter WASM grammar modules were compiled
upfront by V8, exhausting the WASM Zone allocator.
Changes:
- initGrammars() now only initializes the tree-sitter WASM runtime (Parser.init()),
no longer eagerly loads all grammar files
- New loadGrammarsForLanguages() loads only grammars for languages actually present
in the project (e.g. a Dart project loads ~2-3 grammars instead of 16)
- Orchestrator detects needed languages after file scan, before parsing begins
- Embedding pipeline now uses quantized model (~67MB vs ~270MB) to further reduce
WASM memory pressure when embeddings are enabled
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.
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.
