Colby McHenry e5897d0334 feat: remove reasoning offload / CodeGraph AI managed reasoning feature
Strips the bring-your-own-model reasoning offload and managed CodeGraph AI
integration (login/logout/usage commands, offload config/credentials/reasoner
modules, and the synthesizeOffload call in codegraph_explore). The eval findings
showed raw source output outperformed the synthesized path on accuracy, so
codegraph_explore reverts to returning verbatim retrieved source exclusively.

CHANGELOG and README sections for reasoning offload are removed; test comments
and DEFAULT_MCP_TOOLS description are updated to drop offload references.

Colby McHenry e7d9f8c6fa feat(explore): surface interface/registry dispatch boundaries and window oversize spine methods
Two gaps closed in `codegraph_explore` output quality:

**Interface/registry dispatch (#687 extension).** When a named token resolves to
a large same-name family (≥8 members) that doesn't land on the connected flow, the
static path truly ends there — the target is chosen at runtime from N implementations
(plugin/strategy/handler interface). `buildPolymorphicBoundaries` detects this via
`implements`/`extends` edges, ranks candidate supertypes by their TRUE graph-wide
implementer count (not FTS sample frequency, which is biased), and emits a
"## Interface dispatch" section naming the supertype, implementer count, and a few
concrete targets. Fires only for uncovered named tokens; a connected flow stays silent.

**Oversize spine method windowing.** A flow entry that is a god-method (e.g. n8n's
962-line `processRunExecutionData`) previously lost the per-file budget to denser
peripheral blocks and was dropped, forcing the agent to `Read` it back. The spine
call site (edge line to the next hop) is now tracked via `spineCallSites` and used
to window the method to its signature head + a ±28-line band around the call, keeping
it under the OVERSIZE_SPINE_LINES threshold. Spine clusters also rank first in the
budget sort and may exceed the per-file cap up to a 2.5× ceiling so they can never be
starved by co-flow files.

Test suite gains an `interface dispatch` describe block (announce, silent-on-connected,
silent-below-threshold) and uses `beforeAll`/`afterAll` to pin `CODEGRAPH_OFFLOAD_DISABLE=1`
so structural assertions are hermetic regardless of machine config.

Colby McHenry 4f8782cbe5 test(agent-eval): add output-style A/B harness, cost/token analyzer, and DISALLOW/REP_START controls
Three additions to tighten the eval loop:

- offload-eval-styles.sh: new 4-arm eval (raw/refs/map/src) isolating the Worker's
  output shape's effect on main-session tokens, latency, and accuracy. Delegation
  blocked by default (DISALLOW=Agent) so variance from Haiku subagent spawning doesn't
  contaminate the measurement.
- offload-eval-cost.mjs: cost/token analyzer that reads Claude Code's own per-model
  accounting (modelUsage.costUSD) rather than re-deriving from raw token counts,
  giving a correct main(Sonnet)/sub(Haiku) split with proper per-tier pricing.
- offload-eval-3arm.sh: adds DISALLOW env to block sub-agent delegation across all
  arms, and REP_START to append reps to an existing run without clobbering earlier
  jsonls (e.g. REP_START=4 REPS=3 → reps 4,5,6).

Also adds CODEGRAPH_OFFLOAD_STYLE forwarding to the managed gateway so the styles
eval can drive output shape end-to-end; the field is stripped before the upstream
model call and never sent to BYO endpoints.

Colby McHenryandClaude Opus 4.8 7ddd3fa7eb test(agent-eval): persist offload accuracy/adoption eval harness + front-load hook
Reproducible suite measuring the managed CodeGraph AI offload and the front-load
UserPromptSubmit hook (approach 1) vs raw codegraph and no-codegraph, across repo
sizes, on time / main-session tokens+cost / CodeGraph-AI tokens+cost / accuracy.
All agent arms run claude -p sonnet --effort high; eval-only, nothing shipped.

- offload-eval-setup.sh: clone + index 4 memory-probe-verified "not-trained-on" repos
  (mtkruto/postybirb/shapeshift/trezor — small→large) so the no-codegraph baseline is honest.
- offload-eval-3arm.sh / -frontload.sh: one repo, the arms (offload/raw/nocg, frontload).
- offload-eval-matrix.sh / -frontload-matrix.sh: drive all 4 tiers.
- offload-eval-hook.mjs: the front-load hook (self-locates its engine; CG_FRONTLOAD_DEBUG to log).
- offload-eval-metrics.mjs / -judge.mjs (Sonnet) / -summarize.mjs: extract, score, aggregate.
- offload-eval-ground-truth.json: source-verified canonical flows (the judge's reference).
- offload-eval.md: usage + the 2026-06 findings (raw = the win; offload least-accurate;
  front-load solves adoption but exposes explore's dynamic-dispatch gaps).

Scripts are path-portable (self-locating $HERE/$ENGINE; AGENT_EVAL_OUT scratch dir).

Colby McHenry 6d5cb6b25c feat(reasoning): add CODEGRAPH_OFFLOAD_DISABLE kill-switch and per-call usage log
`CODEGRAPH_OFFLOAD_DISABLE=1` immediately disables the offload for the current
process without touching the persisted config or stored login — useful for A/B
arms or sessions where raw source is preferred.

`CODEGRAPH_OFFLOAD_USAGE_LOG=` appends one JSONL entry per call with token
counts, charged credits, and derived cost (`creditsCharged / 100_000`) so a
harness can attribute CodeGraph AI spend to a single run independently of the
server's cumulative totals. Both features are best-effort and never disrupt the
degradable offload path.

Also fixes the `login` credit display to check `unlimited` before the numeric
balance, so comped/internal accounts don't incorrectly show "0 remaining".
2026-06-18 21:10:10 -05:00
Colby McHenry c9e207a0f2 feat(cli): add codegraph usage command to show AI balance and recent usage
Adds a `usage` subcommand that pings `/v1/usage` with the stored token and
displays balance, plan, 30-day explore/token counts, and allowance reset date.

Degrades quietly in all non-happy-path states — signed out, BYO endpoint, or
unreachable server — so managed reasoning remaining optional doesn't change.

Also extends `OffloadUsage` with the fields the endpoint already returns
(`unlimited`, `banned`, `tokensLast30`, `callsLast30`, `creditsLast30`) that
were previously untyped.

Colby McHenry 193722de45 feat(cli): replace offload subcommands with browser device-authorization login / logout
The old `offload` command family required users to paste a token manually (`offload login --token `) and exposed bring-your-own-endpoint plumbing (`set-endpoint`, `status`, `disable`) as top-level CLI surface. This replaces it with a standard OAuth device flow (RFC 8628 shape) against the CodeGraph dashboard.

`codegraph login` calls `/api/cli/device/start`, opens the browser to the returned URL, polls `/api/cli/device/token` until the user approves, then stores the minted token and enables managed reasoning. `codegraph logout` clears it. BYO-endpoint configuration moves entirely to env vars (`CODEGRAPH_OFFLOAD_URL` / `CODEGRAPH_OFFLOAD_KEY` / `CODEGRAPH_OFFLOAD_MODEL`), keeping the CLI surface minimal.

Colby McHenryandClaude Opus 4.8 da5c6c2f79 feat(offload): managed tier (CodeGraph AI) — metered reasoning via org token [WIP]
Adds the managed offload mode: point codegraph_explore at the CodeGraph AI metered
gateway (https://ai.getcodegraph.com) with an org token instead of a BYO provider key.
Same synthesis client, pointed at codegraph-ai-proxy (a metered OpenAI-compatible gateway).

- credentials.ts — org token in ~/.codegraph/credentials.json (0600); unlike a BYO
  provider key it's a revocable org-scoped auth token (gh/npm-login style), kept out
  of config.json
- config.ts — managed branch in resolveOffload: default gateway URL + public model id
  (openai/gpt-oss-120b) + login token as bearer; managed requires a token to be enabled
- reasoner.ts — fetchUsage() reads the credit balance from /v1/usage
- bin/codegraph.ts — `codegraph offload login --token <t>` / `logout`; status shows the
  managed tier + live balance

Proven GREEN end-to-end against a local wrangler-dev of the proxy: org token validated,
credits prechecked, real Cerebras synthesis returned, and credits metered + charged
(250,000 → 248,473). Graceful degrade on upstream failure; balance via /v1/usage.
Phase 3 (codegraph login device flow) replaces the manual --token.

Colby McHenryandClaude Opus 4.8 db4c9f3641 feat(offload): reasoning offload for codegraph_explore (bring-your-own endpoint)
codegraph_explore can now hand the source it retrieved to a reasoning model you
point at — any OpenAI-compatible endpoint (Cerebras, OpenAI, a local vLLM/Ollama)
with your own key — and return that model's tight, cited answer instead of the
raw source dump. The agent's main context gets the answer in far fewer tokens, at
the cost of one network round-trip.

Off by default. Configure with `codegraph offload set-endpoint <url> --model <m>
--key-env <ENV>` (or the CODEGRAPH_OFFLOAD_* env vars); status/disable manage it.
The API key is never written to disk — the config stores the NAME of an env var
and the key is read from it at call time. Strictly degradable: any failure
(no endpoint, network, timeout, empty answer) returns null and the call falls
back to the local source, so the offload can never surface an error to the agent.

Colby McHenryandClaude Opus 4.8 798cd0e21c fix(explore): keep multi-term backend files from being buried by a denser frontend layer
codegraph_explore's file sort is primarily driven by Random-Walk-with-Restart
graph-centrality mass, seeded from the query's text matches. In a cross-layer
monorepo (an API server alongside a much larger, internally dense frontend that
mirrors the same domain words), that mass skews to the bigger layer — so a
backend service/handler that genuinely matches several query terms, even when
it's the #1 search hit, sorts below hits=0 frontend files and gets truncated out
of the response, and the agent reads it back.

Add a corroboration tier above the graph signal: a file that is BOTH an
entry/central file AND matched by >=2 distinct query terms is kept in. The
entry/central guard prevents an incidental multi-term file (a type/util file
that isn't the flow) from displacing a graph-central answer file — a blunt
hits-only tier regressed that case. Single-layer repos are unaffected. Gated by
CODEGRAPH_RANK_NO_MULTITERM=1.

Colby MchenryandGitHub f34f606342 feat(extraction): same-file value-reference edges for impact analysis — 15 languages (#897)
Adds same-file value-reference edges (reader symbol → const/var it reads) so impact analysis catches a constant's same-file consumers, closing the 'change this table, break its readers' hole. 15 languages validated S/M/L on public OSS: TS/JS/tsx, Go, Python, Rust, Ruby, C, Java, C#, PHP, Scala, Kotlin, Swift, Dart, Pascal/Delphi (+ Svelte/Vue/Astro inherited). Edges-only — node count identical on/off; default ON, CODEGRAPH_VALUE_REFS=0 opts out.

2f6316500d feat(extraction): enable same-file value-reference edges by default (TS/JS) (#895)
Value-reference edges (same-file `references` edges from a reader to the
file-scope const/var it reads) shipped behind CODEGRAPH_VALUE_REFS pending an
agent A/B. The A/B is in: on excalidraw the edges are correct and precise (node
count unchanged) and they transform the impact/blast-radius API — `impact` on a
const consumed by 103 readers goes from 1 affected symbol to the full radius.
That blast-radius API is what `codegraph impact` and CodeGraph Pro's verdict
engine consume, so the win is impact correctness; the agent path showed no
regression. Flip the default on; CODEGRAPH_VALUE_REFS=0 disables.

Also close the one precision gap the A/B surfaced: a bundled/Emscripten
`const Module` re-declared as an inner `var Module` / param produced false
positives (nested readers resolve to the inner binding). isGeneratedFile() is
path-only and can't catch content-minified bundles, so prune SHADOWED targets at
the syntax level — drop any value-ref target whose name is bound by more than one
`variable_declarator` in the file. On excalidraw this removes the 23 false
positives while preserving every real reader (impact unchanged at 170).

Adds regression coverage (there was none): same-file readers are edged, they
surface in the impact radius, shadowed consts are NOT edged, and
CODEGRAPH_VALUE_REFS=0 emits nothing.

b49147eab0 fix(cli): make codegraph index a full rebuild so it stops reporting 0 nodes (#874) (#894)
`codegraph index` ran extraction against the already-populated DB without
clearing it first. On an unchanged tree every file's content hash still
matched, so the orchestrator skipped re-inserting all of them and the run
reported its delta (after - before = 0) as "0 nodes, 0 edges" — which read as
if `index` had wiped the graph. `init` only ever differed because it runs on a
freshly created, empty DB.

Clear the existing graph before re-indexing so `index` rebuilds from scratch
and reports the same complete result as a fresh `init`. `--force` keeps its
role as the home-dir/root-path override; `sync` stays the incremental path.

Adds an end-to-end regression test driving the built binary (init -> index),
asserting the graph stays populated and the summary is never "0 nodes, 0 edges".

ab107b325a fix(watcher): warn (don't degrade) on Linux inotify watch exhaustion (ENOSPC) (#893)
On the Linux per-directory watch path, hitting fs.inotify.max_user_watches
surfaces as ENOSPC — which the degrade logic added for #876 (EMFILE/ENFILE
only) did not catch, so it fell through to the silent "skip this directory"
branch: a large repo got a partial watch set with no hint why edits in
unwatched directories stopped auto-syncing.

ENOSPC is non-fatal — raise the limit and partial watching keeps working — so
it now warns ONCE, naming the exact knob (fs.inotify.max_user_watches, with the
sysctl to set it), instead of degrading. It also stops attempting further doomed
watches for the session (every inotify_add_watch would fail too). Installed
watches keep firing; `codegraph sync` / git sync hooks cover the remainder.

Validated on macOS (forced per-directory path) and real Linux (Docker) — the
new test asserts a single warning naming fs.inotify.max_user_watches, no
degrade, and a live partial watch.

beca7116a0 feat(mcp): surface degraded watcher state to the agent in tool responses (#892)
When live file watching permanently degrades (watch-resource exhaustion, or a
write lock held past the retry budget), getPendingFiles() goes empty — so the
existing per-file staleness banner can't fire even though the index is now
frozen and silently drifting stale. The agent kept getting clean-looking
responses off a no-longer-updating index.

Read-tool responses now lead with a whole-index banner ("CodeGraph auto-sync
is DISABLED…") whenever the watcher is degraded, and codegraph_status gets a
dedicated "Auto-sync disabled" section. Both carry the degrade reason and tell
the agent to Read files directly. Expose isWatcherDegraded() /
getWatcherDegradedReason() on the CodeGraph class, and document the new banner
in the MCP server instructions.

Completes the agent-notification half of #876 (the operator-facing onDegraded
wiring shipped in #891).

cea4d086f9 fix(watcher): degrade cleanly on watch exhaustion and prolonged lock contention (#891)
The live file watcher could stay "alive" after it had stopped being
trustworthy. EMFILE/ENFILE watch-resource exhaustion only logged (and was
silently tolerated on the Linux per-directory path), and prolonged
LockUnavailableError retried forever at the normal debounce cadence — both
left auto-sync dead while the index silently drifted stale. Especially bad
for long-running MCP/daemon sessions.

Add a one-way degrade(): on watch-resource exhaustion (any watch strategy)
or on lock contention past a bounded exponential-backoff budget, log once,
fire a new onDegraded callback, and stop. start() now returns false
consistently when the per-directory path degrades at startup — it previously
returned true on Linux, so the MCP server reported the watcher "active" when
it had degraded. Wire onDegraded into the MCP server so callers are actually
told, and expose isDegraded()/getDegradedReason().

Builds on the approach in #877 by @thismilktea. Validated on macOS
(recursive), Linux (per-directory, Docker) and Windows (recursive) — 30/30
watcher + watch-policy tests on each.

Closes #876

5cc155ddc4 fix(index): skip nested git worktrees instead of indexing them as duplicate repos (#848) (#868)
A git worktree nested in a project (e.g. Claude Code's gitignored
`.claude/worktrees/<name>/`) was swept into the index as an embedded repo: its
`.git` is a FILE pointing into the host repo's `.git/worktrees/`, and embedded-
repo discovery treated any `.git` (file or directory) as a distinct repo to
index. Each worktree then duplicated the entire graph — one report went from
~1,850 files to 24,533, with search/explore flooded by stale copies.

classifyGitDir() now distinguishes:
- `.git` directory       -> embedded clone, index (#193/#514/#622, unchanged)
- `.git` file → worktrees/ -> worktree, skip (#848)
- `.git` file → modules/   -> submodule, index (unchanged)

Applied at both embedded-repo entry points: findNestedGitRepos discovery (which
also covers the sync/change-detection path) and the untracked-subdir recursion
in collectGitFiles.

Verified: the reproduction drops from 6 files / betaHelper×3 to 3 files / ×1,
with a genuine embedded clone and submodules still indexed. Regression test added.

64ff7597d0 fix(cli): stop serve --mcp from confusing humans — hide it + explain on a TTY (#867)
`codegraph serve --mcp` is the stdio MCP server an AI agent launches for itself
(the installer wires it into every agent's MCP config), not a command a human
runs. Run by hand in a terminal it just hung waiting for JSON-RPC, looking
broken.

- Hide `serve` from `--help` (commander `{ hidden: true }`); it stays fully
  invocable, so agents are unaffected.
- When stdin is an interactive TTY (a person — never the agent's pipe or the
  detached daemon), print what it is and point to `codegraph status` /
  `codegraph daemon`, then exit instead of hanging.
- README: drop `serve --mcp` from the CLI Reference and stop the troubleshooting
  section from telling users to run it; keep the accurate "your agent launches
  it" note.

Verified: agent path intact (22 MCP handshake/daemon tests pass), `serve` absent
from --help, and the TTY path prints the message and exits cleanly.

f7441f2124 fix(resolution,cli): cross-file static method calls + affected path normalization (#825) (#865)
Cross-file `ClassName.staticMethod()` calls resolved to the class, not the
method: the import resolver matched the receiver `Foo` to the named class
import but dropped the `.bar` member, and createEdges then mis-promoted the
`calls` edge to `instantiates`. So callers/impact for the static method came
back empty. Descend from the resolved class into its `Container::member` so the
call links to the method; fall back to the class when no such member exists
(non-`::` languages and genuine class references are unaffected).

Also normalize `codegraph affected` inputs to the project-relative,
forward-slash form the index stores, so `./src/x.ts`, an absolute path, and a
Windows back-slash path all match (previously silently returned 0).

Validated on luxon (24 files): node/edge totals identical (no explosion), 69
mis-promoted `instantiates` edges become `calls`, and real static factories
(DateTime.fromISO, etc.) resolve their callers. Full suite: 1534 passed.

070ce4da2b feat(cli): codegraph version command + complete CLI Reference (#864)
* feat(cli): codegraph version command + complete CLI Reference

Add a `codegraph version` subcommand plus the `-v` and `-version`
spellings (commander already wires up `--version`/`-V`), so the version
is easy to reach however a user guesses at it. The `-v`/`-version` forms
are intercepted before commander parses — its version short flag is the
capital `-V`, and its parser rejects a multi-character single-dash flag.
A trailing `-v` on a subcommand still means `--verbose`.

Document the previously-missing commands in the README CLI Reference:
`daemon`/`daemons`, `unlock`, `telemetry`, `version`, and `help`.

Colby MchenryandGitHub ff288ac711 feat(cli): one interactive codegraph daemon command, replaces stop/list (#863)
Collapses the unreleased daemon controls into a single interactive command.
`codegraph daemon` (alias `daemons`) opens an arrow-key picker (current project's
daemon first, pre-selected), enter stops it, or pick "Stop all"; non-TTY prints a
plain list. Removes stop/list/ps; reuses the unchanged daemon-registry machinery;
the pick->stop loop is in daemon-manager.ts behind an injectable select (unit
tested). Validated live on macOS/Linux (real clack picker driven via pty) and
Windows (real runDaemonPicker + stopDaemonAt against a real daemon). Closes #845

Colby MchenryandGitHub 0f825649a1 feat(cli): codegraph stop / list to manage background daemons (#861)
Adds first-class daemon control (the #845 pain point: no clean way to stop a
runaway daemon). `codegraph stop [path]` stops the current/given project's
daemon (SIGTERM -> SIGKILL fallback, sweeps artifacts); `stop --all` stops every
daemon; `list`/`ps` shows running daemons (--json for scripts).

Discovery via a small self-healing registry: each daemon records its root under
~/.codegraph/daemons/ on start, removes it on graceful shutdown; readers prune
dead pids. Cross-platform by construction (files + process.kill). Validated live
on macOS, Linux (docker), and Windows (VM): registry unit 6/6 and real-daemon
stop/list 6/6 on each.

Colby MchenryandGitHub 2472508549 fix(installer,cli): refuse to index $HOME / filesystem root (#860)
Running the installer or `codegraph init`/`index` from $HOME auto-indexed the
entire home tree (installer indexes process.cwd() with no guard), producing a
multi-GB ~/.codegraph/codegraph.db; the install dir sharing the ~/.codegraph
name then made every home subdir resolve its root to $HOME. On pre-1.0 macOS the
per-file watcher over that tree exhausted kern.maxfiles and crashed the machine
(#845; the fd blowup was fixed in 1.0.0, this fixes the root cause).

Add unsafeIndexRootReason() and refuse the home dir, a parent of home, and
filesystem roots at the installer auto-index, `init`, and `index`. Overridable
with --force. Closes #845.

TerminateProcess, seen as signal=null + non-zero code, not 'SIGKILL'. Assert

Colby MchenryandGitHub 1702dfc544 fix(mcp): make the liveness watchdog a separate process, not a worker thread (#858)
The worker-thread watchdog from #856 didn't work in the real daemon — caught by
live-testing against a real serve --mcp. V8 isolates coordinate on global
safepoints, so a main thread wedged in a tight non-allocating loop (#850's
SourcePositionTableIterator::Advance) strands the watchdog worker before it can
SIGKILL.

A separate child process shares no isolate/heap with the parent, so the wedge
can't touch it; it kills via the kernel. Parent heartbeats to the child's stdin;
silence past the timeout -> SIGKILL; parent exit closes the pipe -> child exits.
Validated live (real daemon SIGKILLed in ~timeout); regression test covers the
non-allocating-wedge-under-heap-pressure case. API/install points/CHANGELOG
unchanged; the broken worker version was never released.

Colby MchenryandGitHub 576149e062 feat(mcp): worker-thread liveness watchdog to self-kill a wedged main thread (#856)
Belt-and-suspenders follow-up to #855. Any non-yielding sync loop on the main
thread wedges the event loop, and nothing running on that loop (timers, signal
handlers, PPID watchdog) can recover it — only another thread can.

A tiny worker thread (in the detached daemon + direct modes) watches a
shared-memory heartbeat the main thread bumps each event-loop turn; if it stops
advancing across enough consecutive checks (~CODEGRAPH_WATCHDOG_TIMEOUT_MS,
default 60s) the worker SIGKILLs the process so a fresh daemon starts on the next
connection. Counts consecutive stale checks (not wall-clock) so it's immune to
clock jumps / sleep; tuned never to fire on real work; opt out with
CODEGRAPH_NO_WATCHDOG=1.

Colby MchenryandGitHub 3476ac9a27 fix(mcp): exit on uncaught exception instead of orphaning/spinning at 100% CPU (#855)
The process-wide uncaughtException handler logged the error and kept running. For
the detached `serve --mcp` daemon that turned any escaped fault into an
unrecoverable orphan: nothing respawns it, and when logging the raw Error hit a
V8 source-position loop while lazily formatting `.stack`, the main thread wedged
at 100% CPU so even the PPID watchdog / idle-timer could no longer fire. Same
failure mode as #799, which only fixed the stdin-'error' trigger.

Restore Node's default fatal semantics: render a bounded, hang-proof line (name +
message only — never read `.stack`) then exit non-zero, so a fresh daemon starts
on the next connection. Extracted to src/bin/fatal-handler.ts with injectable
seams; unit-tested incl. the never-touch-stack invariant.

Closes #850.

06a410e9b4 feat(extraction): R language support (#828) (#839)
R has no declaration syntax — everything is an expression — so the
extractor works through the visitNode hook: functions in every
assignment form (incl. nested, attributed to their enclosing scope),
top-level variables/constants, library()/require() imports and
source() file references (claimed, Lua-style), S4/RefClass/R6/ggproto
classes with their methods and extends edges, setGeneric/setMethod.
Grammar vendored from r-lib/tree-sitter-r v1.2.0 (ABI 14; npm package
is a security placeholder, tree-sitter-wasms has no R).

Benchmarked on AnomalyDetection (8/8 named defs), dplyr (1027 fns),
ggplot2 (150 ggproto classes / 597 methods / 128 extends edges —
adding ggproto mid-bench flipped the large-repo A/B from a regression
to 2.4x faster than the no-codegraph arm).

2c7bbd5387 fix(extraction): C# record-struct kind fidelity + bodiless positional records (#831 follow-up) (#838)
The shipped grammar parses every record form as record_declaration (no
record_struct_declaration node), so 'record struct' mis-kinded as class.
classifyClassNode now distinguishes the value-type form by its struct
keyword child, and extractStruct accepts bodiless positional records
(the no-body gate is for C/C++ forward declarations) instead of
crashing mid-file on them.

ed117ef90b feat(index): multi-repo workspaces index as a whole (#514) (#837)
A workspace holding several independent git repos failed two ways:

- Enumeration: a super-repo whose .gitignore hides its child repos
  (/packages/) indexed 0 of their files — git never lists ignored dirs,
  and the #193 embedded-repo recursion only fired for UNTRACKED dirs.
  Gitignored embedded repos are now discovered (ignored-dirs listing +
  bounded .git search) and enumerated by their own git ls-files.
- Change detection: git status in the parent says nothing about embedded
  repos (untracked OR ignored), so codegraph sync missed every child
  change. Status now recurses per embedded repo.

ScopeIgnore is the new single source of truth for indexer + watcher
scope: parent rules for ordinary paths, the child repo's own rules for
paths inside it, built-in defaults uniformly on full paths (a git repo
inside node_modules is an npm git-dependency, not project code), and
ancestors of embedded roots are never pruned (the Linux per-directory
watcher must descend to reach them).

Non-git workspace roots already worked via the per-directory gitignore
walk — locked in by test.

13b2575dfe fix(installer): opencode global config goes to ~/.config/opencode on every platform (#535) (#836)
* fix(installer): opencode global config goes to ~/.config/opencode on every platform (#535)

opencode resolves its config dir with xdg-basedir (XDG_CONFIG_HOME ??
~/.config) unconditionally — it never reads %APPDATA%; that layout
belonged to the discontinued Go fork. Writing there on Windows meant
opencode never saw the MCP entry.

- globalConfigDir(): drop the win32 APPDATA branch; XDG resolution everywhere
- install/uninstall (global): sweep a stale codegraph entry + AGENTS.md block
  out of the legacy %APPDATA%/opencode location (siblings/comments untouched)
- detect(global): a legacy-only dir still counts as installed so the sweep
  is reachable
- tests are env-gated, not platform-gated, so the whole matrix runs on any
  OS; the suite previously pointed APPDATA and XDG_CONFIG_HOME at the same
  dir, which is exactly how the divergence stayed invisible

Supersedes the prefer-if-exists approach of #670 (greenfield installs --
before opencode's first run -- would still have fallen back to APPDATA).

* test(installer): match legacy sweep paths by dir prefix, not 'AppData' substring

On Windows os.tmpdir() lives under AppData\Local\Temp, so every harness
path contains 'AppData' and the substring assertions false-positive.
Caught on the real Windows VM.

df6f4bec43 feat(explore): dynamic-dispatch boundary surfacing — announce where a flow ends instead of guessing edges (#687) (#835)
* feat(explore): announce dynamic-dispatch boundaries when a flow can't connect statically (#687)

When buildFlowFromNamedSymbols can't connect the agent's named symbols, scan
the disconnected symbols' bodies (query-time, deterministic, zero graph
mutation) for dynamic-dispatch forms — computed member calls, getattr,
reflection, typed message buses, runtime-keyed emits, Proxy — and announce
the exact site where the static path ends, with candidate runtime targets
when a dispatch key is statically visible. The honest alternative to
guessing edges: surface the boundary, don't fabricate the bridge.

* fix(agent-eval): ab-new-vs-baseline survives files added since the baseline ref

A single multi-file 'git checkout <ref> --' with one unknown pathspec checks

A 2-node chain populates pathIds but renders nothing (Flow needs >=3), and
the dynamic-links section skipped its edge as 'already in the main chain' —
so a custom EventBus emit→handler connection was invisible. Skip-as-in-chain
now applies only when a chain actually renders, and the boundary scan treats
short-chain endpoints as connected.

848fde9f59 feat(telemetry): anonymous usage telemetry — documented schema, opt-out, public ingest worker (#834)
Adds anonymous usage statistics (commands/tools used, languages indexed,
connecting agents) with a strict, auditable allowlist. Never code, paths,
file/symbol names, queries, or IPs.

- src/telemetry/: zero-dep client — consent resolution (DO_NOT_TRACK >
  CODEGRAPH_TELEMETRY > stored choice > default-on), random machine UUID,
  in-memory counters → capped JSONL buffer → completed-day rollups; sync
  exit-append (survives process.exit) + opportunistic bounded sends; the
  first-run notice gates the first SEND, never local buffering, so the
  installer's consent toggle always precedes it. Off is off: no recording,
  no socket, buffered data deleted.
- codegraph telemetry status|on|off; per-command counting via preAction hook.
- MCP: tool counting after the reply is on the wire (session + proxy
  in-process fallback), agent attribution from initialize clientInfo,
  unref'd daemon flush interval. Zero hot-path cost, zero stdout.
- Installer: visible default-on consent toggle (asked once, never re-asked),
  install/index/uninstall lifecycle events.
- telemetry-worker/: public Cloudflare Worker behind telemetry.getcodegraph.com
  — allowlist validation, IP stripping, per-machine rate limit, forwards to
  PostHog as anonymous events. Ships nowhere with the npm package.
- TELEMETRY.md (field-by-field contract) + README section + design doc.
- 20 unit tests; suite-wide CODEGRAPH_TELEMETRY=0 guard so tests never
  pollute real telemetry. Full suite: 1448 passing.

nothing. Both separators now route to file mode, normalized to forward
slashes (the form the index stores). Symbols never contain either
separator in any indexed language.

Validated: macOS smoke (explore/node symbol/node file/unindexed
refusal) + Linux Docker (same smoke + full suite, 1428 passed).

adcb862f8e fix(cli): explore/node not-indexed error stops agents from running init themselves (#821)
The message said "run 'codegraph init' first" — an instruction-shaped
error that invites an agent hitting it (e.g. a subagent following the
global instructions block into an unindexed repo) to index the project
uninvited: minutes of CPU and a surprise .codegraph/ the user never
asked for. Every other layer already encodes indexing-is-the-user's-
decision (the MCP NotIndexedError guidance, the inactive instructions,
the conditional block); the CLI now matches: continue with your usual
tools, do not run init yourself, the project owner can enable it.

e2f1fe4b2a fix(installer): instructions block is scope-neutral — conditional on .codegraph/ existing (#820)
A global install writes the block into user-scope files
(~/.claude/CLAUDE.md, ~/.codex/AGENTS.md) that apply to EVERY repo the
user opens — the unconditional "This repository is indexed" claim was
false in unindexed ones and would send subagents into failing codegraph
calls, the exact noise the unindexed-session policy (#817) eliminates.
Now: "In repositories indexed by CodeGraph (a .codegraph/ directory
exists) …" plus an explicit skip-entirely line for the no-index case.

Residual: the delegation A/B validated the assertive project-scoped
wording; the conditional form keeps the same active ingredients (the
codegraph name + both command surfaces in the relay-able slot) — fold a
re-check into the next delegation A/B run.

8170d181f2 feat(cli+installer): codegraph explore/node CLI + instructions-file block — subagent & non-MCP reach (#704) (#819)
Task-tool subagents never see the MCP initialize instructions and hold
the MCP tools only as deferred names they rarely think to load — so
delegated work bypassed codegraph almost entirely (measured ~1 of 9
forced-delegation runs touched it; the rest did 30-50 grep/read calls).
Two additions close the gap:

- CLI: `codegraph explore` and `codegraph node` call the same ToolHandler
  as the MCP tools and print identical output — the graph for any agent
  with a shell (subagents, Gemini CLI, raw Codex, humans).
- Installer: each agent target (claude/codex/gemini/opencode) writes a
  short marker-fenced CodeGraph section into its instructions file —
  the one channel subagents DO receive — naming both surfaces. Upsert
  self-heals the stale pre-#529 long block; uninstall strips it; re-runs
  are byte-equal unchanged. (#529's duplication argument bounded the
  size: four lines, commands only.)

A/B (excalidraw, sonnet/high, forced Explore-agent delegation): without
the block, subagent codegraph usage ~1/9 runs; with it, 4/4 — subagents
ToolSearch-load the MCP tools and run explore 5-7x, best runs with ZERO
Read/grep (80-95s vs 150-197s baseline). The block's mechanism: the
parent relays the note into the task prompt, making the deferred tool
names salient.

Contract tests updated to the new expectations (write + self-heal
replace the #529 strip-only behavior); README install/guidance sections
refreshed (they also still described the pre-#817/#818 tool surface).

c450fd95b7 feat(mcp): default tool surface trimmed to 4 — explore, node, search, callers (#818)
callees/impact/files/status stay fully functional (handlers, CLI, library
API untouched; CODEGRAPH_MCP_TOOLS re-enables any) but are no longer
LISTED by default. Evidence: codegraph_impact appears in zero recorded
eval runs ever; its blast-radius info already arrives inline on explore
(Blast radius section) and node (dependents note). callees is redundant
by construction (a symbol's body IS its callee list). files/status
"reduce to one grep" per the tiny-repo audit, and staleness banners
already inline pending-sync. callers stays: exhaustive call-site
enumeration (incl. callback registrations, per-definition sections) is
the one job explore/node don't replicate. Fewer tools = fewer mis-picks
+ ~300 schema tokens saved per session; presence itself steers.

server-instructions rewritten around the 4-tool surface ("what does X
call" → node body+trail; "what breaks" → callers + inline blast radius).
Tiny-repo gate unchanged (its trio ⊆ the default set); stale gate
comment corrected (context/trace are long gone — its "5 core tools" are
today's trio).

f9fcc2cd6a feat(mcp): unindexed sessions go quiet — empty tools/list + inactive instructions, no-error policy (#769) (#817)
An MCP session in a workspace with no .codegraph/ previously got the full
"lean on codegraph for everything" playbook plus all 8 tools, then every
call returned isError — and one or two early errors teach an agent to
abandon codegraph for the whole session (maintainer-observed). Now the
initialize response picks an instructions variant by index state (cheap
sync walk-up, #172 respond-fast contract holds) and tools/list serves an
EMPTY list when unindexed: absence is the one signal an agent can't
misread. Indexing is deliberately the user's call — the inactive note
tells the agent not to run init itself.

No-error policy in the tool handler: expected/recoverable conditions
(NotIndexedError — cross-project query to an unindexed path, default-
project detection miss) return SUCCESS-shaped guidance instead of
isError; security refusals (PathRefusalError) stay hard errors without
retry encouragement; genuine internal failures keep isError but add a
retry-once note so a transient blip doesn't convert to permanent
abandonment. Principle recorded in CLAUDE.md.

Also: codegraph_search kind:"type" (advertised by its own schema enum)
silently matched nothing — now maps to type_alias; codegraph_explore's
query param no longer tells agents to run codegraph_search first
(contradicted explore's call-FIRST design); server-instructions
§Limitations rewords the unindexed case to stay-out-for-the-session.

0682681175 chore(agent-eval): standing A/B model policy — sonnet + high effort, never Opus/Fable (#816)
All agent A/B arms now run claude --model sonnet --effort high by default
(MODEL/EFFORT env overrides exist). Sonnet is the deliberate floor model:
codegraph's users attach whatever host they already run (Cursor Composer,
Gemini, ...), and a stronger model's tool-use masks the salience problems a
weaker one exposes — what lands on Sonnet generalizes up; Opus/Fable-only
wins don't generalize down. Policy recorded in CLAUDE.md's validation
methodology; 11 hardcoded --model opus call sites across 9 eval scripts
switched to the env-overridable default.

823ffd1c3d feat(extraction+resolution): Astro support — frontmatter/template extraction + src/pages routes (#768) (#815)
.astro files were not indexed at all, leaving a typical Astro site mostly
invisible to search/impact/explore. New AstroExtractor (Svelte/Vue SFC
pattern): component node per file, TS frontmatter + <script> blocks
delegated to the TypeScript extractor, template {fn(...)} calls (incl. the
multiline `{posts.map((post) => (` opening line), PascalCase component-tag
references. New astroResolver: Astro global + astro:* virtual modules as
framework-provided, component resolution with the #764 ambiguity rule,
src/pages/ file-based routes ([param]→:param, [...rest]→*rest, _-prefixed
and *.config.* excluded). SFC languages now preload the TS/JS grammars
their extractors delegate to (a pure-SFC file set previously had none
loaded). Also fixes a pre-existing Svelte/Vue script-block off-by-one that
reported every script symbol one line low.

Validated per the playbook: stalux (the issue's repro) 54/54 .astro files
indexed, getIconNode found at its exact line, 14/14 routes, 93.0% fair
cross-file coverage; AstroPaper 27/27 components, 13/13 routes (underscore
dirs correctly excluded), explore connects page→Card→Datetime through the
jsx-render synthesizer; node/edge counts stable across re-syncs.

763ee9c825 fix(resolution): Svelte/Vue component resolvers get the #764 ambiguity rule (#814)
Follow-up to #813: the React resolver's blind components[0] fallback was
the demonstrated wrong-edge source, but the Svelte and Vue resolvers had
the same flaw in their own shape:

- svelte: resolveComponent fell back to components[0] across the whole
  repo when no same-directory match existed — an arbitrary pick among
  same-named components in a multi-app monorepo.
- vue: resolveComponent returned the FIRST basename-matching .vue file
  found anywhere in the tree; its same-directory pass below was
  unreachable dead code. apps/a/Button.vue vs apps/b/Button.vue was a
  file-enumeration-order coin flip.

Both now follow the #764 rule: same-directory first, otherwise only an
UNAMBIGUOUS name resolves — ambiguity falls through to the name-matcher's
proximity scoring instead of guessing.

Safety: zero-delta A/B on the README's own framework benchmark repos
(sveltejs/realworld — the 100% Svelte coverage repo — and nuxt/movies,
93.5% Vue coverage) plus the excalidraw control: node counts identical,
zero calls or references edges changed. Single-app repos have unique
component names, so the rule only bites where the old behavior was
already a coin flip. Full suite 1398 passed.

Also verified the #813 per-definition tool grouping is language-agnostic
(probed Go same-named functions across packages — grouped identically to
the TS fixture).

222af6b87c fix(mcp+resolution): stop conflating same-named symbols across monorepo apps (#764) (#813)
A NestJS-style monorepo has one UserService/UserModule/UserRepository per
app; with no package concept for TS they share one global name scope and
agents visibly warned that CodeGraph was mixing unrelated classes.

Two distinct problems, two fixes:

1. TOOL AGGREGATION. callers/callees returned one merged list across every
   same-named match, and impact merged all their blast radii into a single
   overstated subgraph. Now: matches group into DISTINCT DEFINITIONS
   (filePath + qualifiedName — same-file overloads still merge, that's the
   overload feature) and render one file-labeled section per definition;
   a new `file` argument (path or suffix, like codegraph_node's) narrows
   to one definition, suppressing the stale aggregation note; a
   non-matching `file` falls back to all definitions with a note.
   server-instructions documents the behavior.

2. RESOLUTION WRONG EDGES. Auditing a real monorepo (amplication, 54k
   nodes) found 1,036 cross-package `references` edges into duplicated
   names. Root cause: the React framework resolver ran PascalCase
   component resolution on refs from PLAIN .ts FILES (a GraphQL types
   file's own `Account` type alias lost to an arbitrary same-named CLASS
   in another package — the resolver's blind `components[0]` fallback at
   confidence 0.8 outranked the name-matcher's proximity-correct 0.7).
   Component resolution is now gated to JSX-capable refs (tsx/jsx) and
   never guesses among multiple candidates without a positional signal
   (same-dir / component-dir / unique). Cross-package wrong edges:
   1,036 -> 40 (-96%; the remainder are genuine shared-model imports and
   codegen template scaffolds), with the freed refs re-resolving to the
   correct same-file/same-package targets. excalidraw (a real React repo)
   is a zero-delta control — legitimate component refs all carry
   same-dir/component-dir signals.

Graph-level separation was verified correct on a fixture before any
changes (import + proximity resolution keeps apps apart) — the conflation
was tool-level plus the react-resolver edge class.

Tests: 6-test e2e suite (grouped callers/callees, per-definition impact
radii, file narrowing, fallback note, cross-app edge isolation) + react
resolver unit tests updated to production reality (tsx refs resolve,
plain-ts refs decline). Full suite 1398 passed. EXTRACTION_VERSION
23 -> 24 (re-index to drop the wrong cross-package edges).

Closes #764

dce61a5f4a fix(extraction): qualified Type::member refs skip the name gate — no-import references resolve (#812)
`KtHandlers::handle` registered from another file produced no edge: the
extraction gate required the scope to be a same-file type or an IMPORTED
name, but Java/Kotlin same-package references and Kotlin companion members
need no import at all, so the gate could never see them. (The "companion
members extract unqualified" limit recorded during Arc A was a probe
artifact: a SINGLE-LINE `class X { companion object { … } }` is an
upstream tree-sitter-kotlin misparse (ERROR node); real multi-line
companions extract transparently as qualified methods of the class.)

Qualified `Type::member` candidates now skip the name gate the same way
`this.<member>` ones do: the explicit-ref syntax is self-selecting, and
resolution stays scope-suffix-anchored + unique-or-drop, so a
`Decoy::handle` can never match a `KtHandlers::handle` ref (tested).

A/B vs main: rxjava +4 (same-package `Maybe::just` / `Single::just`
method refs), fmt +3 (gtest `&Test::DeleteSelf_` /

1f15f93feb feat(extraction): PHP string/array callables + Ruby lifecycle-hook symbols (#811)
The last two deferred callback-registration shapes from #756, each scoped
to positions where the reference is trustworthy:

PHP — a string is a callable ONLY in a known callable position:
  - string args of core HOFs (usort, array_map, array_filter,
    call_user_func*, preg_replace_callback, spl_autoload_register,
    set_error_handler, … — PHP_CALLABLE_HOFS): ungated (PHP globals are
    referenced cross-file without imports) + resolution unique-or-drop,
    function-kind only ('Cls::m' strings resolve qualified)
  - array callables anywhere in call args: [$this, 'method'] routes through
    the class-scoped this. resolver (parents included); [Foo::class,
    'method'] resolves qualified
  - strings to arbitrary functions: deliberately nothing

Ruby — hook-DSL symbols name a method of the enclosing class:
  (skip_)?(before|after|around)_* / validate / set_callback /
  helper_method / rescue_from(with:) symbols → class-scoped this.<sym>,
  riding the supertype pass so `before_action :authenticate` in a
  controller resolves to ApplicationController's method. `validates`
  (plural) excluded — its symbols name ATTRIBUTES. Class-body-level hooks
  attribute to the CLASS node (the scoped resolvers now accept class-like
  from-nodes).

Also hardened while validating: the this.X supertype pass is now
NODE-anchored — file-anchored class node → implements/extends edge targets
→ contains-anchored member lookup — replacing the name-keyed
getSupertypes walk, which unioned every same-named class's parents (rails
has a dozen `Engine`s) and produced a cross-class wrong edge.

A/B vs main: WordPress +556 (14/14 sampled genuine — [$this,'m'] wiring,
array_map('absint',…), sodium polyfill call_user_func_array dispatch);
rails/rails +385 after the node-anchored fix (16/16 sampled genuine, incl.
inherited hooks across real extends edges); controls byte-stable
(excalidraw 0-delta, redis identical, typeorm keeps its +4 inherited
getters). The only calls-edge deltas anywhere are pre-existing
minified-bundle resolution jitter (wp-tinymce.js single-letter symbols).

Full suite 1391 passed. EXTRACTION_VERSION 21 → 22 (re-index to benefit).

38095aa95b feat(resolution): inherited this.X, Java/Kotlin cross-file method refs, Swift type scoping (#810)
Three callback-registration shapes deferred from #756/#808, one arc:

1. INHERITED this.X (TS/JS + every this.-routed language): a `this.<member>`
   registration whose member isn't on the enclosing class defers to a second
   pass (resolveDeferredThisMemberRefs — in-memory like deferredChainRefs,
   runs after implements/extends edges persist, same lifecycle as the #750
   conformance pass) and resolves up the supertype chain, depth-capped BFS,
   validated targets only. `bus.on("submit", this.handleSubmit)` in a
   subclass links to FormBase::handleSubmit; same-named methods on unrelated
   classes never match. this.-prefixed candidates skip the extraction name
   gate (an inherited member can't be in definedHere).

2. JAVA/KOTLIN qualified method refs: `Handlers::onMessage` /
   `OtherClass::handle` emit QUALIFIED names resolved by the scoped
   suffix-matcher — cross-file capable, gated on the scope name being a
   same-file type or an imported name (dotted JVM imports now contribute
   their last segment). `this::m` and `super::m` route through the
   class-scoped resolver (super rides the supertype pass). References
   through a VARIABLE (`subscriber::onNext`) deliberately produce nothing —
   receiver type is unknowable; RxJava's baseline bare capture was resolving
   these to same-named same-file methods (a test method "registering" an
   anonymous class's onNext) — the rework drops 18 such wrong edges and
   keeps the 7 genuine Type::method refs RxJava's main tree actually has.

3. SWIFT enclosing-type scoping (implicit self): bare callback names match
   methods only of the from-symbol's own type (extension/nested scopes
   reconciled by suffix), and top-level code never matches methods.
   Alamofire: −44 wrong edges (parameters like `request`/`data`/`retrier`
   resolving to same-named methods on unrelated protocols), all verified;
   the same-class param collision (`task`) remains and is documented.

New ResolutionContext.getNodeById lets matchers derive the from-symbol's
class scope. Controls: redis/fmt fnref edges byte-identical; excalidraw
stable; typeorm +4 genuine inherited-getter dependencies; zero calls edges
changed on any of 7 A/B repos; nodes identical everywhere. Kotlin
companion-object members extract unqualified (pre-existing) so
`Type::companionFn` stays silent rather than guessing — documented.

Full suite 1389 passed. EXTRACTION_VERSION 20 → 21 (re-index to benefit).

38eb4e688c fix(extraction): classify TS/JS class fields by value — properties, not methods (#808) (#809)
Every TS `public_field_definition` / JS `field_definition` extracted as a
method-kind node, so a plain field (`public fonts: Fonts;`) was reported
as callable: class shape was misrepresented, kind-based filtering was
defeated, and bare-name call resolution landed on data fields — typeorm's
boolean `ColumnMetadata::isArray` field was soaking up Array.isArray(...)
call edges (685 such wrong edges on typeorm alone).

Classification now follows the VALUE (classifyMethodNode hook, mirroring
resolveBody's callable detection): arrow-function / function-expression
fields and HOF-wrapped ones (`onScroll = throttle(() => {…})`) stay
methods with their bodies walked; everything else becomes a property that
keeps its type-annotation references edge, visibility, static-ness, and
decorators. Field initializers are now walked too (`history =
createHistory()` attributes the call to the property — previously
invisible), and JS class fields — whose name lives in the grammar's
`property` field, so they never extracted a symbol at all — now appear in
the graph (resolveName on the JS extractor).

With fields correctly kinded, `this.X` callback registration is re-enabled
for TS/JS (removed in #807 because field pseudo-methods made it mostly
wrong): `this.<member>` candidates resolve CLASS-SCOPED
(resolveThisMemberFnRef) — the target must be a function/method sharing
the from-symbol's qualified-name class prefix, same file, no fallback —
so `addEventListener("online", this.onOfflineStatusToggle)` and API-object
wiring (`{ mutateElement: this.mutateElement }`) produce registration
edges to the enclosing class's own method, while `this.fonts` (a
property) and inherited/unknown members yield no edge.

A/B (baseline = #807 main): excalidraw / typeorm / express — node counts
identical on all three; kinds shift method→property only (typeorm: exactly
7,406 swapped; excalidraw also corrects 5 anonymous-class mock fields that
were function-kind); every one of the 736 dropped call edges targeted a
node that is now a property (calls into data fields — verified 100%);
gains are retargets to real callables, initializer-call attributions, and
+74/+7 class-scoped this.X registration edges (sampled: addEventListener/
removeEventListener wiring, imperative-API method maps). Full suite green
(1386).

EXTRACTION_VERSION 19 → 20 (re-index to benefit).

Closes #808

8a114ba53c feat(extraction): capture function-as-value — callback registration sites in callers/impact (#756) (#807)
A function name used as a VALUE — passed as an argument
(signal(SIGINT, handler), qsort(..., compare)), assigned to a function
pointer or field (ops->recv_cb = my_cb, OnClick := Handler), or placed in
a struct initializer / handler table ({ .recv_cb = my_cb },
{ "get", getCommand }) — produced no edge in ANY of the 19 tree-sitter
languages, so registered callbacks looked dead and their registration
sites were invisible to callers/impact.

This adds table-driven function-as-value capture across all 19 languages
(plus the wrapper forms: &fn, &Cls::method, Java Class::m, Kotlin ::f,
Swift #selector, ObjC @selector, Ruby method(:sym), Scala eta, Pascal
@Handler), gated at extraction (same-file definitions + imported
bindings; C-family file-scope initializers are constant-expression
contexts and skip the gate, which is how redis-style cross-file command
tables resolve), and resolved by a dedicated strategy: function/method
targets only, same-file first, unique-or-drop cross-file, no fuzzy
fallback ever. Edges persist as kind 'references' with metadata.fnRef,
so getCallers/getImpactRadius surface them with zero graph-layer
changes; MCP callers/callees label them "via callback registration".

Precision rules bought by real-repo false positives (full A/B record in
docs/design/function-ref-capture.md): C++ is &-explicit outside
file-scope tables (fmt's begin/out/size collisions; out-of-line member
defs are function-kind); TS/JS/Python bare ids resolve to functions only
(TS class fields extract as method-kind — pre-existing quirk); Swift
refuses same-file method overload-families; param-forward shapes
(this.x = x, value: value) and destructuring are skipped; minified
bundles (*.min.js) produce no candidates.

Validated on 17 public OSS repos (redis, excalidraw, gin, bytes, okhttp,
okio, Alamofire, flask, sinatra, Newtonsoft.Json, scopt, provider,
busted, Fusion, AFNetworking, PascalCoin, fmt): node counts identical,
zero calls edges lost or gained, references strictly additive
(+3,200 registration edges total), precision spot-checked by reading
sampled source lines (redis 30/30, flask 8/8). Deliberately NOT covered:
indirect-dispatch resolution (o->cb(x) → impl) — that needs data-flow
through struct fields, and a wrong edge is worse than none.

EXTRACTION_VERSION 18 → 19 (re-index to benefit).

Closes #756

0df9246752 fix(extraction): capture & clean docstrings across all README languages (#780) (#806)
* fix(extraction): capture docstrings for export/const/decorator-wrapped symbols (#780)

getPrecedingDocstring walked previousNamedSibling from the EMITTED
declaration node, so it only found a leading comment when the comment was
a direct sibling of that node. For a declaration nested under a wrapper —
`export class X` / `export const f = () => {}` (export_statement /
lexical_declaration), a plain const arrow (variable_declarator), or a
decorated Python def/class (decorated_definition) — the comment is a
sibling of the WRAPPER, so the inner node had no preceding comment and
the docstring was stored as NULL.

Climb out through the wrapper node(s) before scanning for the comment.
Each wrapper holds exactly one declaration, so this can't mis-attribute a
comment to a sibling (verified: an uncommented method does NOT inherit its
class's comment). Also strip leading `#` from Python/Ruby/shell line
comments, which the cleanup chain missed (Python docstrings used to keep
their `#`).

Query/extraction-layer change to a parse helper; re-index to pick up
docstrings on already-indexed files. Verified on the reporter's JS/TS and
Python repros (8/8 now captured) plus over-walk controls; +3 tests.

* fix(extraction): clean comment markers across all supported languages (#780)

Validating docstring capture across every README language surfaced that
the marker cleanup only knew C-style `//` and `/* */`, plus the `#` added
earlier this branch. Doc comments in other styles were captured but left
their markers in the stored text:

  - Rust/Swift/Kotlin doc lines `///` and `//!`  -> leading `/` / `!` leaked
  - Lua/Luau `--` and `--[[ ]]`                  -> not stripped
  - Pascal `{ }` and `(* *)`                     -> not stripped

Extract the cleanup into cleanCommentMarkers() and handle every style.
Paired block delimiters are stripped only when the comment OPENS with one,
so a line comment that happens to end with `}` / `*)` / `]]` is never
truncated; per-line markers stay anchored at line start.

Validated end-to-end (extract -> index -> codegraph_node output) across
all 19 tree-sitter code languages plus Svelte/Vue `<script>` blocks: every
one now stores and returns a clean docstring. +1 cross-language test.

0b1a2eed97 fix(mcp): treat a stdin 'error' as shutdown so the server can't orphan/spin (#799) (#805)
A stdio MCP server's lifeline is stdin: when the host/client goes away,
stdin should end and the server should exit. The server paths listened
for stdin 'end'/'close' but NOT 'error'.

That gap bites with a socket-backed stdin — the shape VS Code / Claude
Code use (a socketpair, not a pipe). On client death the socket can
surface as an 'error' (ECONNRESET/hangup) instead of a clean 'close'.
Unhandled, it escalated to the process-wide uncaughtException handler,
which logs and keeps running — so the server orphaned instead of
exiting. On Linux a POLLHUP socket fd left registered in epoll then
wakes the event loop continuously, pinning a core at 100% CPU; once the
main thread spins, the setInterval PPID watchdog can't even fire, so the
orphan runs forever (the report's 28+ minutes).

Add treatStdinFailureAsShutdown(): listen for 'error' as well as
'end'/'close', and DESTROY the stdin stream on any terminal event so the
fd leaves epoll and can't churn, then run the path's shutdown. Wired into
the live paths — startDirect, the local-handshake proxy, and
StdioTransport — plus the legacy pipe proxy. Fires once (re-entry guard).

Note: this is hardening for a class of failure that matches every piece
of the report's evidence (socket stdin, userspace main-thread spin, high
involuntary context switches, watchdog never firing), but the exact 100%
CPU spin could not be reproduced in Docker (Linux) across /dev/null EOF,
socket peer-death (RST/FIN), the reporter's 0.9.7 bundle, and the npx
chain — all exited cleanly — so the trigger is environment-specific.

d0e649969a fix(graph): treat class instantiation as a caller/callee edge (#774) (#804)
`callers <Class>` returned "No callers found" (or only the importing
file) even when a class's constructor was called from many sites, and
the instantiation sites were invisible — the opposite of what "what
breaks if I change this class?" should answer.

The `instantiates` edges already existed in the graph, correctly
attributed to the constructing function; they were simply excluded from
the caller/callee traversal, which queried only calls/references/imports.
Constructing a class is calling its constructor, so add `instantiates`
to the edge-kind set in both getCallers and getCallees (kept symmetric so
they stay inverses and `trace` can cross the instantiation boundary,
function -> class -> its methods). impact already traversed all edge
kinds, so it was unaffected.

Query-layer only — existing indexes benefit on upgrade with no re-index.
Verified on a Python fixture: `callers Supervisor` now returns the
construction sites (main/work/test_it), and a new graph test asserts
main() <-> DerivedClass via the instantiation. Full suite green.

9a0f144770 fix(directory): self-heal a stale .codegraph/.gitignore so daemon.pid is ignored (#788) (#802)
Versions <= 0.9.9 wrote an explicit-allowlist .codegraph/.gitignore
(*.db, cache/, .dirty, ...) that never listed daemon.pid or the socket,
so the daemon's runtime pidfile got committed. The wildcard rewrite in
#654/#492/#484 fixed new inits, but the file is only written when
absent, so existing installs kept their stale file forever — the fix
never reached the people hitting it.

Make the gitignore self-heal: ensureGitignore() writes the file if
absent and upgrades a stale CodeGraph-generated default in place,
leaving a user-authored file untouched. A "stale default" is one that
carries our `# CodeGraph data files` header but predates the wildcard
ignore (no bare `*` line) — a header match heals every historical
variant (v0.7.x..0.9.9, all verified to share it) and is idempotent.
validateDirectory() runs on every open()/openSync(), so existing repos
heal on the next codegraph command after upgrading. The duplicated
template (previously inlined in two formats) is consolidated into one
GITIGNORE_CONTENT constant.

c39b4b938e docs(readme): fill framework-coverage gaps — add Play, Vue/Nuxt, Scala (#798)
The framework story was missing several supported frameworks:

- Play (Scala/Java) — absent from both the Framework-aware Routes table and
  the routing-coverage line. Measured 76.3% (106/139 routes resolved to a
  handler) across the 31 verb-route apps in playframework/play-samples; every
  miss is Play's framework-provided `Assets` controller (vendored library
  code, not app source). Slots into the convention-ceiling bucket.
- Vue Router / Nuxt — recognized (file-based pages/, server/api/, middleware)
  but missing from the routes table.
- Scala + Vue — missing from the "20+ Languages" highlight.

File-based routers (SvelteKit, Vue/Nuxt) have no separate handler edge — the
page IS the handler — so their coverage is the fair-coverage language figure
(Svelte/SvelteKit 100%, Vue/Nuxt 93.5%), now cited explicitly.

Existing framework numbers left untouched (they were measured ad-hoc; a fresh
re-measure would shift them and isn't part of this gap-fill).

b7b7c8b4e8 docs(readme): update Pascal/Delphi coverage 75.7% → 77.4% (#797)
The paren-less call extraction (#793) and free-routine attribution (#795)
added real call coverage on PascalCoin. Controlled A/B on a fresh clone,
same source-file filter, only the build differing:

  baseline (pre-Pascal-work, d21d2df): 75.79%  (≈ the documented 75.7%)
  current  (main, v18):                77.37%  (+1.58)

The baseline reproducing the documented 75.7% confirms the metric is the
same one the README table uses; the +1.58 is the measured coverage gain
from this session's Pascal extraction work.

dac00e7d44 fix(pascal): attribute a free routine's calls to it, not the file (#795)
A Pascal/Delphi procedure or function defined ONLY in the implementation section
(no interface declaration, not a class method) had no node of its own, so
extractPascalDefProc's caller lookup fell through to the nodeStack top — the file
node. Every call in such a routine's body was lumped under the unit: callers
returned the file, and impact couldn't attribute the call to the routine. (Methods
were fine — they get a node from their class declaration.)

Fix: when extractPascalDefProc finds no existing node for a FREE routine (a name
with no `.`), create a function node for it and attribute the body's calls to it.
Interface-declared free routines already have a node (found via the methodIndex),
so there's no duplicate; methods keep their existing class-declaration node.

PascalCoin A/B: +511 / -145 — the +511 are calls now correctly attributed to their
actual routine (`allocate_new_datablock -> TDisposables::GetMem`), replacing -145
file-level aggregates; +248 new function nodes for the implementation-only
routines. New synthetic test asserts a free routine's call attributes to it
alongside a method caller. EXTRACTION_VERSION 17->18. Full suite green.

done (#793) — `Obj.Free;` / `TFoo.GetInstance.DoIt;` are now extracted (scoped to

35dce04e1f feat(pascal): extract paren-less method calls (Obj.Free; / TFoo.GetInstance.DoIt;) (#793)
Pascal/Delphi lets a no-arg method or procedure drop its parens, so the call
parses as a bare `exprDot` (not an `exprCall`) and was never recorded as a call —
callers/impact/trace missed all of them (e.g. `Obj.Free`, `List.Clear`, the
paren-less factory chain `TFoo.GetInstance.DoIt`).

extractPascalParenlessCall handles these, wired into visitPascalBlock scoped to
STATEMENT position only: a bare `Obj.Field;` statement is a no-op, so a
statement-level dot expression is a call — but a dot in assignment LHS/RHS or a
condition is left alone, since there it's genuinely ambiguous with a
field/property access. The chained paren-less form reuses the #750 chain encoding
(gated on the Delphi `TFoo`/`IFoo` type convention) and resolves the same way.

PascalCoin A/B: +1131 / -1 — purely additive, and all 1131 new edges resolve to
METHOD nodes (zero field/property false positives, confirming the statement-level
gate). 3 new synthetic tests (paren-less call, paren-less chained factory, and the
property-write/read non-extraction guard). EXTRACTION_VERSION 16->17. Full suite green.

af56f3539d fix(pascal): resolve chained factory calls TFoo.GetInstance().DoIt() (#750) (#791)
Ports the #645/#608 chained-receiver mechanism to Pascal/Delphi — which I'd
previously mis-scoped as blocked. The paren'd chained form extracts fine; it just
hit the chained-call gap like the others (with a decoy, `TFoo.GetInstance().DoIt()`
mis-resolved to a same-named method on an unrelated class).

- pascal.ts: getReturnType reads the method's `typeref` (a `function GetInstance:
  TBar` returns TBar; an interface return `IFoo` is captured too).
- tree-sitter.ts: extractPascalCall now re-encodes a chained call `TFoo.GetInstance().DoIt`
  (the exprDot's receiver is an exprCall) instead of collapsing it to bare `DoIt`.
  Gated on the Delphi type-naming convention (`TFoo`/`IFoo`) so a capitalized
  VARIABLE chain (Pascal capitalizes locals too — `Curve.X().Y()`, `Self.X().Y()`)
  stays bare and keeps its existing bare-name resolution.
- name-matcher.ts: `pascal` joins the dotted-chain gate + CHAIN_LANGUAGES +
  CONSTRUCTS_VIA_BARE_CALL (a `TFoo(x)` typecast yields a TFoo). When the factory's
  return type wasn't captured (a `constructor Create` has no `: TBar` but returns
  its class), resolve the method on the factory class itself. resolveMethodOnType
  validates, so a wrong inference yields no edge.

Validation: 4 synthetic tests (factory+decoy, constructor chain, typecast chain,
absent-method safety). Real-repo A/B on PascalCoin (772 files): +19 / -18 — 15 of
the -18 are correct class→interface retargets (`GetInstance(): IAsn1OctetString`
resolves `.GetOctets` on the declared interface, not baseline's concrete-class
guess); 3 are negligible drops (0.02%). EXTRACTION_VERSION 15->16. Full suite green.

d21d2dfa50 fix(objc): resolve chained message-send calls [[Foo create] doIt] (#750) (#786)
Ports the #645/#608 chained-receiver mechanism to Objective-C. A message send
whose receiver is itself a message send — `[[Foo create] doIt]` — used to drop
the receiver, so `doIt` name-matched a same-named method on an unrelated class
(commonly a test helper's `init` or an Apple-SDK method).

- objc.ts: getReturnType reads the method's `method_type`, SKIPPING nullability /
  ARC qualifiers (`nonnull instancetype` must yield instancetype, not `nonnull`).
- tree-sitter.ts: the message_expression branch now re-encodes a chained send
  `[[Foo create] doIt]` as `Foo.create().doIt` when the inner receiver is a
  capitalized class and the outer selector is unary.
- name-matcher.ts: `objc` joins the dotted-chain gate + CHAIN_LANGUAGES. A
  class-message factory returns an instance of the RECEIVER class by convention
  (`instancetype`), so when the factory's own return type isn't recoverable
  (`alloc`/`new`/`shared…` return instancetype, or aren't user nodes), the
  receiver's type is the class itself — this resolves the ubiquitous
  `[[X alloc] init]` and singleton chains. resolveMethodOnType validates against
  the class and its supertypes, so a wrong inference yields no edge.

Validation: 4 synthetic tests (factory+decoy, superclass conformance, absent-method
safety, the nonnull-instancetype singleton). Real-repo A/B on SDWebImage (208 files):
+35 / -75 — all corrections (the -75 are wrong `init` mis-matches to a test helper /
wrong class, retargeted to the right class's init in the +35, plus 2 Apple-SDK chains
on unindexed classes). db stable, no node explosion. EXTRACTION_VERSION 14->15.
Full suite green.

16c73e2b0e fix(dart): resolve chained static-factory / constructor calls Foo.create().bar() (#750) (#762)
Ports the #645/#608 chained-receiver mechanism to Dart, plus makes Dart factory
and named constructors first-class so their chains can resolve at all. A call
whose receiver is itself a call — `Foo.create().bar()` (static factory or
factory/named constructor) — used to drop the receiver to a bare `bar`, which
name-matched a same-named method on an unrelated type (commonly a stdlib
`Option`/`Iterator` `.map`/`.where` mis-tied to the project's own class).

- dart.ts: extractBareCall now re-encodes `Foo.create().bar` when the chain
  starts with a capitalized type; getReturnType captures the return type (generic
  `List<Foo>` → `List`); factory (`factory Foo.create()`) and named (`Foo._()`)
  constructors are indexed as `Foo::create` / `Foo::_` with return type = the
  class (via resolveName + getReturnType + constructor_signature in methodTypes).
- The UNNAMED ctor `Foo()` is deliberately NOT extracted (isMisparsedFunction),
  so plain construction stays an `instantiates` edge to the class rather than a
  call to a phantom `Foo::Foo` method.
- dartCtorInfo validates a "constructor" against the enclosing class name, so a
  method tree-sitter MISPARSES as a constructor — `@override (A, B) m()`, where
  the annotation swallows the record return type and `m()` looks like a one-id
  constructor_signature — is still extracted as the method it is (regression
  found on localsend; covered by a new test).
- name-matcher.ts / index.ts: `dart` joins the dotted-chain gate,
  CONSTRUCTS_VIA_BARE_CALL (case construction), and CHAIN_LANGUAGES (conformance
  for superclass/mixin methods). resolveMethodOnType validates, so a wrong
  inference yields no edge.

Validation: 7 synthetic tests (static factory, factory/named ctor, construction,
conformance, absent-method safety, the misparse regression, instantiation-not-
hijacked). Real-repo A/B on localsend (368 Dart files): hand-written +17/-10 — all
corrections (the -10 = 7 wrong stdlib/extension misattributions removed + 3 ctor
source-renames), plus additive factory/named-ctor call resolution. Instantiation
preserved; no node explosion. EXTRACTION_VERSION 13->14. Full suite green.

2f96f58cbb fix(scala): resolve chained static-factory/apply calls Foo.create().bar() (#750) (#761)
Ports the #645 (C++) / #608 (PHP) chained-receiver mechanism to Scala. A call
whose receiver is itself a call — `Foo.create().bar()` (companion factory),
`Builder(cfg).bar()` (case-class apply), or a fluent chain — used to drop the
receiver to a bare `bar`, which name-matched a same-named method on an unrelated
type. The most common wrong edge was a stdlib `Option`/`Iterator` `.map`/`.flatMap`/
`.foreach` mis-attributed onto the project's own same-named class.

- scala.ts: `getReturnType` reads the `return_type` field — generic `List[Foo]`
  → container `List`, qualified `pkg.Foo` → `Foo`, `this.type` left undefined.
- tree-sitter.ts: re-encode `Foo.create().bar` when the inner call's receiver chain
  starts with a capital (companion factory / case-class apply); instance chains
  (`list.map().filter()`) stay bare.
- name-matcher.ts: `scala` joins the dotted-chain gate + CONSTRUCTS_VIA_BARE_CALL
  (case-class `apply` constructs the class); resolveMethodOnType validates, so a
  non-conventional `apply` returning another type yields no edge, not a wrong one.
- index.ts: `scala` joins CHAIN_LANGUAGES so trait-inherited methods resolve via
  the conformance second pass.

Validation: 4 synthetic tests (factory+decoy, case-class apply, trait conformance,
absent-method safety). Real-repo A/B on gatling (750 Scala files): +14 / -59 unique
edges — all corrections. The +14 are retargets (e.g. `HttpProtocolBuilder(cfg).baseUrl`
now resolves to HttpProtocolBuilder::baseUrl, not the same-named private BaseUrlSupport
helper); the -59 are wrong edges removed (stdlib Option/Iterator monad calls
mis-tied to the project's Validation::*, self-loops, decoy collisions) — zero genuine
factory chains dropped (verified: gatling has no real Validation.success().map() chains).
db stable at 40 MB. EXTRACTION_VERSION 12→13. Full suite green.

ccced9e358 fix(go): resolve chained factory-function calls New().Method() (#750) (#760)
* fix(go): resolve chained factory-function calls New().Method() (#750)

A Go call through a chained factory function — `New().Method()`,
`With(cfg).Build()` — dropped the receiver to a bare method name, which then
attached to a same-named method on an unrelated type (a wrong edge) or didn't
resolve. Ports the #645/#608 mechanism for Go's bare-factory receivers:

- Part 1: capture Go return types; a pointer `*Foo` -> `Foo`, a multi-return
  `(*Foo, error)` -> its first result, qualified `pkg.Foo` -> `Foo`.
- Part 2: encode a bare-factory chain (`New().Method`), gated to an `identifier`
  receiver so instance chains (`obj.Method().Other()`) keep bare-name.
- Part 3: matchDottedCallChain bare-inner Go branch looks up the FUNCTION's
  return type, then resolves+validates the method on it. Wired into the
  conformance pass so a method promoted from an embedded struct (`type Widget
  struct{ Base }` -> the existing `extends` edge) resolves. FALLBACK: when the
  inner isn't a resolvable function (a package-level VARIABLE holding a function
  value, e.g. gin's `engine()`), fall back to bare-name so the edge isn't dropped.

Validated: synthetic decoy + args + multi-return + embedded-conformance + absent
safety tests (4/4); full suite green. Real-repo A/B on gin (99 .go): pre-fallback
-40 = 25 wrong self-loops removed (good) + 15 correct `Engine::ServeHTTP` dropped
(gin's ginS variable-factory `engine()`); the fallback recovers the 15. gin A/B
re-confirm with the fallback is PENDING (local index flakiness, not a code issue).
EXTRACTION_VERSION 11 -> 12.

* fix(go): stop the chained-call fallback from looping the batched resolver

The Go variable-inner fallback (for chains like `engine().ServeHTTP()` whose
inner is a package-level var, not a factory function) resolved the method via
a synthetic bare-name ref and propagated THAT ref as `.original`. Its
`referenceName` was the bare `ServeHTTP`, not the stored `engine().ServeHTTP`,
so `resolveAndPersistBatched`'s keyed `deleteSpecificResolvedReferences` no-oped,
the offset-0 batch never drained, and the loop re-resolved + re-inserted the
same rows forever — a runaway that grew a 99-file repo (gin) to 5,050,206 edges
/ 1.4 GB before filling the disk.

- name-matcher.ts: tie the bare-name match back to the original `ref` so the
  batch-cleanup delete matches the stored row and the loop drains.
- index.ts: add a non-progress guard to resolveAndPersistBatched — if the
  unresolved_refs table doesn't shrink after a batch, stop instead of growing
  the graph without bound (defense-in-depth for any future keyed-delete mismatch).
- resolution.test.ts: regression test for the variable-inner chain — asserts the
  fallback edge resolves AND the edge count stays bounded (no explosion).

gin A/B (post-fix): db 5.8 MB / 3,699 calls edges; net-zero unique-edge diff vs
main (the fallback recovers the dropped edges, adds no wrong ones). Full suite green.

5805f01957 fix(rust): resolve chained associated-function calls Foo::new().bar() (#750) (#757)
A Rust call through a chained associated function — `Foo::new().bar()`,
`Foo::with(cfg).build()` — dropped the receiver to a bare method name, which
then attached to a same-named method on an unrelated type (a wrong edge) or
didn't resolve. Ports the #645/#608 mechanism for Rust's `::` receivers:

- Part 1: capture Rust return types; `-> Self` yields the `self` marker (resolved
  to the impl's own type, like PHP), references/generics are unwrapped/reduced.
- Part 2: encode an associated-function chain (`Foo::new().bar`), gated to a
  scoped_identifier receiver so instance chains (`x.foo().bar()`) keep bare-name.
- Part 3: resolve via matchScopedCallChain (PHP's `::` resolver, generalized),
  validated by resolveMethodOnType. Wire Rust into the conformance second pass
  (matchScopedCallChain variant) so a chained method provided by a trait the type
  implements (`impl Trait for Type` → existing implements edges) resolves too.

Validated: synthetic decoy + args + Self + trait-default-conformance + absent
safety tests; full suite green (lone failure is the known-flaky #662 daemon test,
passes in isolation). Real-repo A/B vs main: clap (329 .rs) a net precision win —
**+937 added (96% correct builder methods), 622 wrong->right retargets**
(`Command::new().arg()` was mis-resolving to `ArgGroup::arg`, now `Command::arg`),
+162 net unique edges; the pure-drops are largely wrong bare-name edges the fix
correctly stops emitting. tokio-rs/bytes 0/0 (no regression). Known limit: the
single-hop mechanism re-encodes only the first hop of a chain (deeper hops keep
bare-name) — clap's unusually deep builder chains are partly covered.
EXTRACTION_VERSION 10 -> 11.

7c7f0dd56f fix(swift): resolve chained static-factory/fluent calls + nested-extension naming (#750) (#755)
Completes Swift in the #750 chained-call series (after Java #751, Kotlin #752,
C# #753, conformance #754). Two parts:

1. Swift chained-call resolution (the #645/#608 mechanism): capture Swift return
   types (positional, member types -> last segment), encode capitalized-receiver
   chains `Foo.make().draw()` / `Foo(args).draw()`, resolve+validate via the
   shared matchDottedCallChain (+ constructor branch). Fixes the decoy wrong-edge
   bug where a chained method dropped to a bare name and attached to a same-named
   method on an unrelated class.

2. Nested-type extension naming fix: `extension KF.Builder: KFOptionSetter` parsed
   as a class_declaration named `KF.Builder` (dot) — inconsistent with the type's
   own declaration `KF::Builder` (name `Builder`) — so the extension's conformances
   and members were invisible to a chained call on the type. A Swift resolveName
   now names a nested-type extension by its last segment (`Builder`), so its
   `implements`/`extends` edges and methods are found by the supertype walk
   (conformance #754) and the simple-name method match.

Validated: synthetic decoy + args + constructor + absent-method tests; full suite
green; nested-extension repro (`KF.url().onSuccess()` resolves via conformance to
the protocol method). Real-repo A/B vs main (conformance) — Alamofire and
Kingfisher both **0 added / 0 removed, node count unchanged**: NEUTRAL and SAFE.
The prior -168 Kingfisher regression (from the naming inconsistency) is eliminated;
Swift's unique-named fluent methods already resolved by bare name, so the chain
path lands the same edges — the value here is decoy-collision correctness, the
nested-extension naming fix, and consistency with the other four languages.
EXTRACTION_VERSION 9 -> 10.

48d4654e8d feat(resolution): conformance-aware chained-method resolution (#750) (#754)
* feat(resolution): conformance-aware chained-method resolution (#750)

A chained static-factory/fluent call whose method lives on a SUPERTYPE the
receiver conforms to — a protocol-extension method (Swift), an interface default
method, or an inherited superclass method — now resolves. resolveMethodOnType
falls back to walking the return type's implements/extends edges (via the new
context.getSupertypes) when the method isn't a direct member. Because those edges
don't exist during the single-pass resolution, a second pass
(resolveChainedCallsViaConformance) re-resolves the deferred chained refs after
edges are built. Still validated, so a wrong inference yields no edge.

aa07dc59d4 fix(csharp): resolve chained static-factory calls Foo.Create().Bar() (#750) (#753)
A C# method called through a static factory or fluent chain —
`Foo.Create().Bar()`, `JObject.Parse(s).Property(...)`,
`Instant.FromUtc(...).InZone(zone)` — lost the receiver's type, so the chained
method didn't resolve and the call was invisible to callers/impact/trace. Ports
the #645/#608 mechanism to C# (additive, like Java #751):

- Part 1: capture C# return types in the extractor, reading the `returns` field
  (`static Foo Create()` -> `Foo`); predefined/array/generic/nullable/namespaced
  types are normalized or skipped.
- Part 2: encode a chained `member_access_expression` receiver
  (`Foo.Create(args).Bar()`) as `inner().Bar` with normalized empty parens, so
  factory calls that take arguments still split. Non-chained member calls keep
  their existing `recv.Method` text.
- Part 3: resolve via the shared matchDottedCallChain (now Java/Kotlin/C#),
  validated by resolveMethodOnType so a wrong inference yields NO edge.

Known limitation (safe): C# extension-method chains don't resolve, since the
method lives on the extension class, not the receiver's type — no edge, never a
wrong one.

Validated: synthetic decoy + args + absent-method safety tests; full suite green;
real-repo A/B on Newtonsoft.Json (945 .cs: +3, 0 lost) and nodatime (488 .cs:

3e04650850 fix(kotlin): resolve chained companion-factory calls Foo.getInstance().bar() (#750) (#752)
A Kotlin method called through a companion-object factory, fluent chain, or
constructor — `Foo.getInstance().bar()`, `Config.create(opts).build()`,
`STMTransaction(f).commit()` — dropped the receiver to a BARE method name, which
then name-matched a same-named method on an unrelated class (a wrong edge) or
failed to resolve. Ports the #645/#608 mechanism to Kotlin:

- Part 1: capture Kotlin return types in the extractor. tree-sitter-kotlin
  exposes no field names, so the return type is read positionally (the type node
  after function_value_parameters); inferred/Unit/Nothing returns yield none.
- Part 2: encode a CLASS/companion-factory call-receiver chain as `inner().method`.
  Gated to a capitalized receiver (`Foo.getInstance()` / `Foo(args)`) so instance
  chains (`list.filter{}.map{}`) keep their bare-name behavior — re-encoding those
  would only drop the edge, regressing recall in fluent codebases.
- Part 3: generalize matchJavaCallChain -> matchDottedCallChain (shared by the JVM
  dot-notation languages); resolve the method on the factory's return type, or on
  the constructed class for a Kotlin `Foo(args).method()` receiver. Validated via
  resolveMethodOnType, so a wrong inference yields NO edge.

Validated: synthetic decoy + args + absent-method safety tests; full suite green;
real-repo A/B on arrow-kt/arrow (734 .kt) — node count identical (no explosion),
+49 validated-correct chained edges, and the removed edges are wrong bare-name
guesses the fix correctly stops emitting (419/438 from test/doc files; the 18
from product code are stdlib `.apply{}`, self-loops, and bare-name mismatches) —

A Java method called through a static factory or fluent chain — `Foo.getInstance().bar()`,
`Config.create(opts).build()` — lost the receiver's type, so the chained method either
didn't resolve at all or (when a same-named method existed on an unrelated class) attached
to whichever class was indexed first. Ports the #645 (C++) / #608 (PHP) 3-part mechanism:

- Part 1: capture Java return types in the extractor (skip void/primitives/arrays,
  unwrap generics, strip package qualifier).
- Part 2: encode a chained-call receiver as `inner().method` with normalized empty
  parens, so factory calls that take arguments still split.
- Part 3: matchJavaCallChain resolves the chained method on the factory's return type,
  validated via resolveMethodOnType so a wrong inference yields NO edge (never a wrong one).

Validated: synthetic decoy + absent-method safety tests; real-repo A/B on google/guava

eb5960b535 fix(php): resolve chained static-factory calls Cls::for($x)->method() (#608) (#749)
A method called through a PHP fluent static factory — `ApiClient::for($c)->createOrder()`,
the canonical Laravel per-credential/per-tenant client idiom — produced no
`calls` edge: the receiver of `->createOrder` is the `Cls::for(...)` static
call, whose result type was never recovered, so the edge was dropped and
`codegraph_callers` returned nothing.

Same shape as the C++ singleton/factory fix (#645), reusing its return_type
column + the chained-call mechanism:
- Capture PHP return types (getReturnType): `: self` / `: static` / `$this`
  stored as the `self` marker, a concrete `: Type` as its short name,
  primitives/unions dropped.
- Encode the chained scoped-call receiver as `Cls::for().method` so the
  resolver can split it (PHP-gated, in extractCall).
- New matchPhpCallChain: look up the factory's return type (`self` → the
  factory's own class; concrete → that class), then resolve AND validate the
  method on it — a wrong inference yields no edge, never a wrong one.

EXTRACTION_VERSION 4->5 (re-index to populate PHP return types + chained edges).

Validated on koel (1383 PHP files): node count identical (no explosion),
0 edges lost, +80 chained-call edges recovered; synthetic tests cover the
self-factory, concrete-return, namespace, decoy, and absent-method cases.

75ae1e8bd9 fix(search): down-weight the project name in ranking — completes #720 (#748)
The per-word path fix (#745) brought the backend to parity but not above:
the project name still gave the lexically-matching stack a residual dir
match + an FTS class-name match, so a backend query that included the
project name still ranked the frontend at/above the backend.

Derive the project name from go.mod module / package.json name / repo dir,
and treat a query word matching it as non-discriminative: drop it from path
relevance and from codegraph_explore's PascalCase type-disambiguation bias
(reporter's suggestions #1/#2) — unless it's the only query word, so a bare
project-name search still scores.

Narrow by construction: the down-weighting fires ONLY when a query word
matches the derived project name (≥5 chars), so every query that doesn't
name the project is byte-identical. On the reporter's repro the backend
controllers now top a backend question that includes the project name;
queries without it, bare project-name queries, and normal symbol queries
are unchanged. Query-time only (no re-index).

afec1282e1 fix(search): score path relevance per query word, not per sub-token (#720) (#745)
A multi-word PascalCase query token — typically a project name a user
includes (`SuperBizAgent backend routes`) — splits into sub-tokens
(superbizagent / super / biz / agent) that ALL match the same path segment,
so path relevance summed +5 four times for one concept. In a mixed-stack
repo that ~doubled every score of the lexically-matching stack's file,
burying the stack the query was about.

Score path relevance per original query WORD instead: a word matches a path
level if any of its sub-tokens do, and counts once — while still splitting
the word (via extractSearchTerms on the original case) so it matches across
naming conventions (`getUserName` → `get_user_name`). Distinct words each
still contribute.

Partial fix: this removes the dominant path over-counting (backend rises
from absent-in-top-6 to parity on the reporter's repro). The residual lexical
edge from the project name in the FTS class-name match + dir match is a deeper
down-weighting change, tracked separately. No re-index needed (query-time).

5b3f5e36db fix(go): attribute calls inside top-level closures to the var, not the file (#693) (#744)
A function called only from an anonymous func_literal at package level — a
cobra `RunE: func(){…}` handler, a goroutine literal, a callback closure
stored in a `var` — had its call leak to the FILE node, because the Go
var-initializer walk ran with an empty scope. So `callers`/`impact` showed
the function with a file (or no meaningful) caller, unlike JS/TS where an
arrow-in-const becomes a named node whose calls attribute correctly.

Scope the Go top-level var/const initializer walk to the declared symbol, so
a call nested in any func_literal initializer (struct field, slice/map,
nested closure) attributes to the enclosing var. EXTRACTION_VERSION 3->4
(re-index to pick up the corrected attribution).

Validated on cli/cli (858 Go files): node/edge counts identical, file-level
dependents byte-identical (no regression), and 62 top-level-closure calls
correctly moved from file-attributed to var-attributed.

35b44e242c fix(scan): don't abort indexing on a non-UTF-8 or unparseable .gitignore (#682) (#743)
A .gitignore transparently encrypted in place by corporate DLP / endpoint
software (UTF-16 header + ciphertext), or one containing a pattern the
`ignore` library can't compile to a regex (`\[` -> "Unterminated character
class"), crashed the entire sync/index. The throw is LAZY — it surfaces at
match time (`ig.ignores()`), not `.add()` — so the existing add-time
try/catch never caught it, and the error never named the offending file.

Read .gitignore defensively: skip a file that isn't valid UTF-8 text whole
(NUL byte or fatal UTF-8 decode), drop only the individual uncompilable
patterns from a text one (probe-compile, then per-line fallback), and warn
with the file path. Indexing continues either way. The watcher inherits the
fix via buildDefaultIgnore.

fd03f31b2c fix(cpp): resolve calls through singletons/factories/chained getters (#645) (#742)
A C++ method call whose receiver is another call's result — `Foo::instance().bar()`,
`WidgetFactory::create().draw()`, `openSession()->run()`, or the same stored in an
`auto` local first — lost the receiver's type during extraction. The callee degraded
to a bare method name, so when two classes shared a method name the call silently
resolved to whichever was indexed first (or not at all), corrupting callers / impact /
trace with a plausible-but-wrong edge.

Three parts:
- Capture C++ return types (new nodes.return_type column, schema v5): the
  function_definition's `type` field, normalized — smart-pointer pointee unwrapped,
  void/primitives dropped.
- Preserve the inner-call receiver in extraction: a C/C++ field_expression whose
  receiver is itself a call is encoded `inner().method` instead of dropping to the
  bare name. Other languages keep the existing behavior.
- New resolution strategy (matchCppCallChain): infer the receiver's class from the
  inner call's return type, then resolve AND validate the method on it. Handles
  singletons/accessors, factories returning a different type, free-function
  factories, make_unique/make_shared/new/direct construction, single-level member
  chains, and namespace-qualified inner calls. A wrong inference yields no edge,
  never a wrong one.

EXTRACTION_VERSION 2->3 (re-index to populate return types).

Validated on the issue repro + spdlog: node count stable (no explosion),
deterministic, and ~100 pre-existing wrong `.size()`-style edges removed.

a56d9e6941 feat(directory): CODEGRAPH_DIR env var to override the index dir name (#636) (#741)
Two environments that share one working tree — most concretely Windows
and WSL — can't safely share a single `.codegraph/`: the daemon lockfile
records a platform-specific pid + socket (named pipe vs Unix socket), and
SQLite locking across the WSL2/Windows filesystem boundary is unreliable,
so two daemons over one index risks corruption.

Add a `CODEGRAPH_DIR` env var (default `.codegraph`) that overrides the
per-project data directory name, so each environment keeps its own index
in the same tree (e.g. `CODEGRAPH_DIR=.codegraph-win` on Windows). The
name is resolved live and validated (rejects separators / `..` / absolute,
falling back to the default with a one-time stderr warning). Indexing and
file-watching now skip ANY `.codegraph-*` sibling so neither side trips
over the other's data.

Routes the previously-hardcoded `.codegraph` literals (db path, lockfile,
error log, watcher ignore, file-scan skip, installer) through the
resolver. No extraction-version bump — index content is unchanged.

636d9fcb7d feat(extraction): index string-literal names in generic tuple type aliases (#634) (#740)
TypeScript service/RPC contracts written as a tuple of generic types —
`type List = [Service<'query_apply_record', Req, Resp>, …]` — carry their
names only as string-literal type arguments, so static extraction never
indexed them and `codegraph query query_apply_record` returned nothing.

Add a narrow TS/TSX type-alias pass that emits each tuple entry's
string-literal name as a `method` node under the alias (qualifiedName
`List::query_apply_record`), making it searchable. Scope is limited to a
direct literal arg of a generic that is a direct tuple element, with a
valid-identifier filter — so utility types (Pick/Omit/Record), deeper
nested generics, and route paths produce no noise.

Bumps EXTRACTION_VERSION so existing indexes get a re-index hint.

Colby MchenryandGitHub 1983590533 feat(mcp): codegraph_node reads files like the Read tool — offset/limit, byte-parity (#738)
Makes codegraph_node a drop-in faster Read for indexed source files (file-read mode: <n>\t<line> like Read, offset/limit, + blast-radius header; symbolsOnly for the map). Fixes the old file-view dropping imports/line-numbers. #383/#527 preserved. Validated by A/B: explore/node already return source + line numbers, so Read=0 when used. Includes the A/B eval harness scripts. Full suite green (1270).

0e2789ab71 docs(agent-eval): nested MCP attach is startup-latency, not a hard block (#735)
Corrects the "run non-nested only" conclusion from #734. The codegraph server
is healthy (handshake ~165ms); the flakiness is that on a multi-step
implementation task the agent dives into Read/grep before codegraph finishes
its ~2-3s startup (worse under nested CPU contention), so it runs with no
codegraph. Fix: pre-warm a persistent daemon (high idle timeout) + skip the
startup re-exec (CODEGRAPH_WASM_RELAUNCHED=1) so claude connects before the
agent's first turn. claude's init snapshot can show status:"pending" even when
it then connects — judge by actual codegraph usage, not the init line.

ab-new-vs-baseline.sh now bakes in the pre-warm + skip-re-exec. Validated: a
clean A/B showed the new build's agent used codegraph 2x / 5 Reads vs the
baseline's 0 / 8 on the same fully-implemented task.

28c5268ee3 docs(agent-eval): evals must run non-nested + add ab-new-vs-baseline.sh (#734)
Running scripts/agent-eval against a `claude -p` spawned from within a Claude
Code session (nested, e.g. from a Bash tool call) makes the codegraph MCP
attach unreliable: the server is healthy (full handshake ~165ms) but the
nested client marks it status:"pending"/0-tools under CPU/timing contention,
so the agent silently runs with no codegraph. NO_DAEMON + `< /dev/null` don't
fix it — it's the nested client, not the server. Documented in CLAUDE.md's
validation methodology.

Adds ab-new-vs-baseline.sh: A/Bs a retrieval/steering change as new-build vs
baseline-build (both codegraph-on, isolating the change — vs run-all.sh's
with-vs-without), on a throwaway copy of an indexed repo. Run it in a real
terminal.

7175dc456c feat(mcp): steer agents to codegraph during implementation + file-view node mode (#733)
* feat(mcp): steer agents to codegraph during implementation, not just Q&A

Two changes targeting agents that reach for Read during edits instead of codegraph:

1. Reframe the agent-facing steering (server-instructions + codegraph_node/explore
   descriptions): drop "consult BEFORE ... not during"; position codegraph_node as
   the Read upgrade for a named symbol (verbatim current on-disk source, safe to
   Edit from, + caller/callee trail), explore PRIMARY / node SECONDARY, with the
   "cached intelligence — better context, fewer tokens" framing.

2. File-view mode: codegraph_node now accepts a `file` with no `symbol` and returns
   that file's symbol map + graph role (its dependents), plus verbatim bodies with
   includeCode — so it can displace a path-keyed Read, not just a symbol lookup.
   Resolves a path or basename; dedups nested members; budget-capped.

To be A/B'd on an implementation task before shipping (per the retrieval doctrine:
steering changes must be measured, not assumed).

10defecc4b fix(mcp): silence the daemon-attach log by default (#618) (#725)
The "Attached to shared daemon" line is benign INFO, but it was written to
stderr — and MCP hosts render all server stderr at error level (and append an
`undefined` data field), so on every session start a healthy attach showed up
as `[error] … undefined`. It is now gated behind CODEGRAPH_MCP_LOG_ATTACH=1:
silent by default, opt-in for debugging daemon attach. Both attach sites
(runProxy + connectWithHello) route through one helper. The daemon integration
tests opt the harness into the log so their attach assertions still observe a
successful attach.

Re-applies the approach from #640 by @mturac.

7fd8b4c185 fix(security): resolve symlinks in path validation to block out-of-root reads (#527) (#724)
* fix(security): resolve symlinks in path validation to block out-of-root reads (#527)

validatePathWithinRoot was purely lexical (path.resolve + startsWith), so an
in-repo symlink whose logical path is inside the project root but whose real
target escapes it passed validation — and both content-serving read sinks
(codegraph_node includeCode, codegraph_explore source) then readFileSync'd it,
leaking out-of-root file contents (e.g. ~/.ssh, /etc) to the agent.

Add a realpath layer: after the lexical check, resolve symlinks on both the
candidate path and the root and re-compare, rejecting anything whose real path
escapes the root. An in-root symlink is still allowed (no over-blocking).
Comparison is case-insensitive on Windows (NTFS + realpath casing). Not-yet-
existing paths (ENOENT) fall back to the lexical result so about-to-be-written
files still validate; other resolution errors reject.

Removes the dead, never-called isPathWithinRoot / isPathWithinRootReal helpers
(the latter a footgun — it returned true on realpath failure). Adds RED->GREEN
tests: in->out file/dir symlinks rejected, in->in allowed, ../ rejected, ENOENT
allowed, plus an end-to-end test proving getCode no longer serves an out-of-root
file reached through a dir symlink.

112e278b5c fix(security): index config files by key only, never surface values (#383) (#722)
Spring `application.{properties,yml}` keys (and Shopify Liquid `{% schema %}`
blocks) were storing the config VALUE in the node docstring, and
`codegraph_explore`'s source section re-read the raw `key = value` line off
disk — so a secret committed to a config file (DB password, API key, JDBC URL
with embedded credentials) could be pushed into an agent's context via
explore/node output without the agent ever opening the file.

Config-leaf nodes (`kind: 'constant'` in a config language) now surface the KEY
only, via a shared `isConfigLeafNode` predicate applied at both surfacing
paths: the value is dropped from extraction, `getCode`/`includeCode` returns
the key instead of the file line, and explore excludes config leaves from
source rendering. The predicate can't match real code (real constants are
ts/java/go/…), so `@Value`/`@ConfigurationProperties` resolution and impact are
unaffected. Adds a regression test asserting a planted secret never appears in
`codegraph_explore` / `codegraph_node` output while the keys still resolve.
