ce0ae30e09 perf(store): resolution ref-index window — kernel-scale resolution 423→276s, 8c envelope ≈11min (§4d round 2) (#1369)
Store-architecture arc round 2. The batched resolution loop reads
unresolved_refs ONLY through the status index + the PK keyset pager;
the other five ref indexes (from_node, name, file_path, from_name,
failed_tail) serve sync-time paths — yet every per-batch DELETE of
resolved refs maintained all of them, the biggest single main-thread
stage on the dubbo profile (deletes 1.2s of a 5.4s resolution phase)
and 50-81s at kernel scale.

beginBulkRefLoad/endBulkRefLoad on DatabaseConnection, threaded as
refIndexLoad hooks next to the existing bulkEdgeLoad pair with the
same minRefsForPool gate (small syncs never pay): drop the five for
the loop, rebuild each in one scan at the end — where the table holds
only the surviving FAILED refs (resolved rows are deleted by then),
so the recreate is near-free. Crash inside the window heals on the
next open (schema.sql re-applies CREATE INDEX IF NOT EXISTS).

Measured:
- dubbo: deletes 1.2 → 0.2s, marks 0.6 → 0.3s, recreate 219ms; wall
  ~8.5s flat — the freed main-lane time shifts into settle (the worker
  lane now binds the double-buffer at medium scale).
- Linux kernel 8c: resolution 423.4 → 275.9s (deletes 50-81 → 3.2s,
  backpressure 16.8 → 7.4s — fewer index writes mean less WAL and
  cheaper folds), ref recreate 10.3s. Envelope ≈ 11.0min, from the
  14.8min pre-arc best; <10min-on-8c now needs ~1 more minute.

Gates: dubbo/gson dumps byte-identical; linux counts exact
2,049,153/6,413,518 and dump sha 6dd1185b… reproduced (10,446,478
lines); full suite green ×2 (153 files / 2588 tests).

69ea438bac perf(kernel): cFnPtr native extraction sweep — step 2, pass 230→151s across the arc (§7a.10) (#1365)
Task #5 step 2. The fuse-then-link refactor (#1364) left the extraction
sweep as a clean per-file boundary: raw text in → collected facts out.
This ports that sweep to the native kernel: `cfnptr_scan_files`
(codegraph-kernel/src/cfnptr.rs) strips and scans a batch of 16 files
per NAPI call, and the TS side only reads files, ships batches, interns
the returned facts, and resolves include paths. The JS sweep remains as
the fallback (no binary, feature detection against older binaries,
CODEGRAPH_KERNEL=0, or CODEGRAPH_KERNEL_CFNPTR=0).

Parity discipline: the JS regexes are the spec, so the scanners are
hand-rolled byte machines reproducing that engine — ASCII \w/\b next to
UNICODE \s (NBSP/U+2000-200A/FEFF decoded from UTF-8), alternation
order, lastIndex resume, and the observable backtracking dimensions
(INIT/ARRAY modifier and struct/star/bracket optionals, DISPATCH's
greedy segment loop); greedy shortcuts only where backtracking provably
can't rescue a match. The native stripper blanks per UTF-16 code unit,
so its output is string-identical to the TS stripper — pinned by a new
kernel arm on the strip differential oracle (fixtures + 500 seeded
random cases).

Gates, all green: new differential suite (adversarial fixture project —
CRLF, NBSP, continuations, decoy strings, unterminated comments,
backtracking shapes — indexed native-vs-JS: identical edge streams,
plus a record-level scanner check); repo differential on
git/redis/vim/SameBoy (identical, 705/852/433/180 edges); probe-hash on
the live linux kernel DB reproduced f6e1713d… (279,335 rows); linux
init counts exact 2,049,153/6,413,518; dump sha 6dd1185b… reproduced
(10,446,478 lines); full suite green ×2 (153 files / 2588 tests).

Measured (8c cg1212, quiet host): cFnPtr sub A=47.9s B=1.1 C=40.9
D=24.1 E=36.8 = 150.9s vs step 1's 179s and the pre-arc 230s (−34%
cumulative); the sweep itself halved (94.5→47.9s, JS strips
132.4k→68.9k). callback-synthesis phase 199.9→171.1s. E's attributed
wall grew from overlap shift under parallel synthesis; the phase total
is the honest number. Full record: plan §7a.10.

c6850d737b perf(resolution): cFnPtr fuse-then-link — one extraction sweep + filtered verbatim linking, pass −22% at kernel scale (#1364)
Task #5 step 1 (plan §7a.8/§7a.9). The C/C++ function-pointer dispatch
synthesizer swept every file's text four times (typedefs, registrations,
propagation, dispatch); at kernel scale the all-or-nothing source cache
declines, so that was 4.4 read+strips per file — 78s of the ~230s pass.

Now ONE extraction sweep reads+strips each file once and collects typedef
names, struct-node field declarations (structurally parsed, fn-pointer
classification deferred until the typedef sets are complete), resolved
includes, an alias-shaped-macro name set, and per-file survival filters
(init type tokens, array element types, inline-struct summaries,
field-assign pairs, dispatch fields/array names — interned, a few MB on
linux). The linking stages then replay the ORIGINAL pass bodies verbatim:
struct layouts register in kind-scan order (same-name precedence is
order-sensitive), and registration/propagation/dispatch run only for
files their filter proves can have side effects, lazily re-stripping just
those. Filters only over-approximate (full-file no-skip scans ⊇ the real
passes' jump-cursor scans), and a filtered-out file is one where every
match fails the pass's own gates before any side effect — parity by
construction. Macro tables stay lazy: a sizing probe found 6.1M #define
lines on linux (amdgpu register headers), ruling out retention.

Measured (8c cg1212, quiet host, fresh kernel init): cFnPtr pass 230s →
179s (−22%); strips 283.5k → 132.4k (4.44 → 2.08/file, 78 → 46.6s);
dispatch stage 95 → 18.5s; callback-synthesis phase 250 → 199.9s.
Standalone probe on the live DB: 139 → 122s.

Byte-parity gates, all green: probe-hash identical on the live kernel DB
(279,335 edge rows both builds); git/redis/vim/SameBoy full dumps
byte-identical old-vs-new (macro tables, commands.def, #ifdef
include-units, inline structs, bare arrays exercised); kernel-parity
0-diffs on git/redis/fmt/protobuf, deferral unchanged; linux counts
exact 2,049,153/6,413,518 and dump sha 6dd1185b… reproduced
(10,446,478 lines); full suite green ×2 (152 files / 2563 tests).

Step 2 (native per-file extractor) now has its boundary: the extraction
sweep, raw text in → records out.

971a5a0483 perf(resolution): worker connection recycling — WAL-depth writes-under-readers fix, superphase −11.4% at 8c (#1362)
The §7a.6 anomaly probed to its mechanism with five discriminating runs
(§7a.7 table): main-thread B-tree writes triple under attached readers
because READERS PIN WAL checkpoint progress — the deep WAL taxes every
writer page operation (deletes 42.6s pool-off vs 118.8s pool-4 on
identical hardware; an aggressive 64MB valve recovers the writes but
overpays +129s in full-park folds; the v2 cache resurrection was
falsified — long-tail name traffic is uncacheable at any capacity).

Fix: workers close and reopen their read-only connections every 8
batches at the double-buffer's worker-idle boundary
(ResolverPool.recycleWorkers + QueryBuilder.rebind + a cadence call).
Reopens are sub-millisecond, resolver caches survive (only prepared
statements re-prepare), and the existing checkpoints advance instead of
parking. Failed recycle downgrades to sequential, same as a failed
fan-out.

Measured (8c pool-4, linux v7.2-rc2, cadence 25 → 8 iterated):
resolution superphase 715.0 → 633.6s (−11.4%), envelope best 14.8min,
recreate 59.7 → 45.3s. Byte-neutral everywhere: git dumps byte-identical
old-vs-new, linux dump sha 6dd1185b reproduced (10,446,478 lines),
counts 2,049,153/6,413,518, suite 2517 green. 2c unchanged by
construction (no pool → no recycling).

d510de4766 perf(synthesis): cFnPtrEdges 2.07x at kernel scale — probe-profiled, edge set hash-identical (#1341)
cFnPtrEdges was 86% of kernel-scale synthesis (306s, §7a.3). Standalone
probe iterations against the live kernel DB attributed and fixed:

- sliceLines split the ENTIRE file per node (~1.6M full-file splits across
  the B/D/E sweeps) — split once per file, slice from the line array
  (D 46.2->20.5s, E 94.5->69.1s).
- The 128-entry strip cache re-stripped every file 4.4x across the four
  file sweeps (71.8s). Sizing is now memory-budget-aware and ALL-OR-NOTHING
  with 5% slack over the file count: a partial LRU on cyclic sweeps thrashes
  to ~0% hit (measured twice: cap ~61k and cap == files both thrashed
  against 63.8k + includes). Full-cache strips: exactly 1.0/file, 15.5s.
- Pass D pre-gates field names on fieldToStructs before the two regex type
  resolutions — a->f = b->g matches every struct-field assignment in the
  tree, ~99% of them data fields.
- recvTypeIn/varTypeIn compiled a new RegExp per call - cached per name.
- Line numbers counted incrementally per match (ascending indexes) instead
  of splitting the body prefix per match; cursor rewinds between the two
  dispatch scans.
- CODEGRAPH_SYNTH_TIMINGS now prints per-sweep walls + read/strip/nodes
  accounting for this pass.

278.8s -> 134.8s standalone at the 2c envelope. Output identity proven at
full scale: probe edge set (merge-dedup applied, canonical sort) SHA256
21c2a971... == the original code's 274,762 edges extracted from the live
kernel DB. Pass suite 15/15.

7cc23668b5 perf(resolution): batch-loop de-quadratic — keyset reads, changes-based guard, DB-scaled valve caps + resolve profiler (#1339)
The §7a.2 per-ref profile overturned the assumption the whole arc was
built on: resolveOne owns only ~93s of the kernel-scale ~433s batch loop.
Loop-stage attribution (CODEGRAPH_RESOLVE_PROFILE, shipped here) named the
rest: backpressure folds 111.2s, count guard 93.9s, batch reads 54.6s,
deletes/inserts/marks ~84s, settle 85.7s.

- Non-progress guard O(remaining)→O(1): the per-batch COUNT(*) walked every
  remaining pending row (O(N²/batch) per run, 93.9s). The cleanup queries
  now return summed SQLite , and zero-removals-from-claimed-work
  is the guard signal — the DIRECT evidence the count diff inferred (a
  mismatched-name resolver makes keyed cleanup no-op ⇒ changes=0). A real
  COUNT runs only on that suspicious path and arbitrates exactly as before.
- Batch reads OFFSET→keyset (54.6s→O(batch)): OFFSET re-walked the
  accumulated failed-row prefix every read; seeking past the last-seen
  rowid is prefix-independent and enumeration-order identical.
- WAL valve caps scale with DB size (env still wins): every fold re-writes
  hot pages (#1231 in bounded form — 111.2s at the flat 256MB cap);
  soft=clamp(dbSize/4, 256MB, 2GB) trades ~4× fewer folds for a transient
  WAL ≈ project size.
- CODEGRAPH_RESOLVE_PROFILE: per-outcome resolveOne histogram + loop-stage
  attribution, main + workers, off by default.

Gates: dubbo dump byte-identical; suite 2,491 passed / 4 skipped (kernel
required). Kernel-scale payoff run lands in the plan doc next.

ca88d3bd15 fix(db,resolution): WAL file cap + cgroup cache credit + pool/parse sizing corrections from the instrumented kernel-scale runs (#1335)
Four §7a.1 instrumented-run findings, each measured:

1. File-size trigger + truncate-at-barrier: a fully-backfilled WAL still
   grows the FILE without bound — the writer only restarts at frame 0 when a
   commit finds zero reader marks, which the instrumented run showed never
   happens (file marched 361→721MB through two COMPLETE backfills; 22GB by
   phase end). backpressure() now also trips at 4× the soft cap on raw file
   size and TRUNCATEs at the parked barrier; the timer path truncates
   opportunistically after complete backfills. Dubbo peak: 251MB → 69MB at
   the same 16MB valve; dumps byte-identical under aggressive folding.

2. cgroup memory credit: memory.current counts reclaimable page cache — a
   post-parse container read 57MB of headroom on a 6GB box and silently
   disabled the pool. inactive_file is credited back (the docker-stats
   working-set convention); the same run now reads a sane 4.4GB budget.

3. Pool at 2 cores reversed: sequential resolution measured FASTER than
   pooled-6-on-2 at kernel scale (853s vs 1,150s), and synthesis is
   Amdahl-bound by cFnPtrEdges (306s of 358s) so pooling it bought nothing.
   cpuCap = min(ap−1, 6), no floor: ap=2 → sequential is the fast path.

4. Parse floor of 2: one parse worker at a 2-cpuset measured 34% slower
   (493s vs 369s) — main + store-worker don't fill the second core. Floor
   restores the baseline (373.5s measured).

Plus the observability §7a.1 burned three 25-minute cycles for: valve
armed/fire/timer-pass/heartbeat lines, checkpoint-worker error capture,
pool sizing decisions (incl. the disabled path), backpressure-hook
presence — all behind CODEGRAPH_SYNTH_TIMINGS / CODEGRAPH_WAL_VALVE_DEBUG.

Suite: 2,490 passed / 4 skipped (kernel required). Kernel-scale record
runs with this build follow in the migration plan §7a.1.

b8833fec57 feat(resolution): memory-aware, cgroup-honest worker-pool sizing + CODEGRAPH_RESOLVE_WORKERS (#1333)
Pool sizing used os.cpus().length, which enumerates the HOST's CPUs: inside
a 2-CPU cpuset it sized 6 resolver workers (the §7a.1 false-'sequential'
premise) and 8 parse workers, and at true 8-core concurrency six ~1GB
workers OOM-killed a 7GB container (oom_kill=5) mid-synthesis — sizing had
no memory term and no override knob.

resolvePoolSize (pure, matrix-tested): explicit CODEGRAPH_RESOLVE_WORKERS
override (0 disables, cap 16); CPU term max(2, min(availableParallelism-1,
6)) — cpuset-honest, floored at 2 so true 2-core boxes keep pooled
synthesis's ~2×; memory term floor(budget*0.7 / clamp(0.2*dbSize, 256MB,
1.5GB)) with budget = min(freemem, cgroup v2/v1 headroom). Parse pool's
core input switches to availableParallelism. Dev machines are unchanged
(still 6 workers); the 8c/7GB kernel-scale container now sizes 4.

6e52295ceb fix(resolution): WAL containment for the pooled superphase — writer backpressure at pool-idle boundaries (#1332)
At kernel scale the pooled resolution/synthesis superphase grew a 22GB WAL
on a 4.6GB DB (cg1212, §7a.1): autocheckpointing is deferred for the run,
and the valve's timer-driven passive checkpoints stay perpetually partial
against the pool's continuous reads — no mechanism ever completed a
backfill, so the WAL accreted the whole phase's write volume, blowing disk
and feeding page-cache pressure into the 8-core/7GB container OOM.

The valve's writer-side backpressure() hard-cap backstop existed but was
wired only into the PARSE orchestrator. Thread it into the resolution batch
loop at the double-buffer's one pool-idle boundary (batch settled, next not
yet fanned out), after the edge-index recreate, and through the synthesis
insert loops. Parked there, the backfill completes; readers re-enter at
SQLite's backfilled mark and the next persist commit wraps the WAL.

Dubbo validation, same build: valve@16MB peak WAL 251MB (floor = the
single-transaction edge-index recreate) vs defaults 914MB; dumps
byte-identical (441,270 rows); wall unchanged (11s). Suite 2,479 green.

4efc6c70e2 fix(scale): kernel-scale hardening — OOM-safe pass skipping + watchdog-safe index recreate (#1323)
Two hazards found by running today's full stack against the Linux kernel
(70,129 files) in the cg1212 repro container:

1. The parallel-synthesis fallback retried a worker-failed pass on the MAIN
   thread. At multi-million-node scale a worker failure is usually a memory
   ceiling, so the retry would OOM the process and take the whole index with
   it. Above 1.5M nodes a failed pass is now skipped with a clear stderr
   message (its synthesized edges are absent; the index completes). Below
   that, the main-thread retry stays — small-scale worker crashes are
   transient and the retry keeps coverage.

2. endBulkEdgeLoad rebuilt all four edge indexes in one synchronous span —
   measured 79s at kernel scale, past the #850 liveness watchdog's 60s
   stall window. A daemon-triggered re-index would have been SIGKILLed right
   after doing the work. Now async with an event-loop yield between builds,
   keeping each stall to a single index (~20s at kernel scale).

Validation: full Linux kernel index to completion in the repro container —
2,048,674 nodes / 6,405,964 edges, EXIT 0, zero passes skipped, on a 2-CPU
VM (worst case: pool disabled, sequential resolution + synthesis) in ~27min.
Phase walls: parse 6.0m, resolution 19.5m (incl. synthesis 6.3m, recreate
79s), maintenance 74s. Suite green (2444).

Also adds docs/design/native-extraction-kernel.md — the spike-validated
design for the native extraction kernel (Rust parse+walk over dubbo's Java:
202ms rayon / 1.07s single-thread vs 4.7s for the current wasm pipeline).

567b4ad4be perf(resolution): drop non-unique edge indexes during the bulk resolution window, byte-identical graphs (#1322)
The resolution persist's measured cost is B-tree maintenance on the edges
table's five indexes (offline replay of a 224k-edge resolution set: 2.8s with
all indexes, 1.1s with only the unique identity index, +0.3s to recreate the
rest). On big runs (same >=150k-ref gate as the resolver pool) the four
non-unique edge indexes are now dropped for the batch loop and recreated in
one pass each before synthesis.

Why this is safe:
- idx_edges_identity stays: INSERT OR IGNORE's dedup conflicts on it (#1034),
  and its leftmost column is `source`, so the only mid-window edge reads —
  resolution's supertype walks (implements/extends by source) — keep an index
  via its prefix (verified with EXPLAIN QUERY PLAN).
- The window closes BEFORE synthesis, whose passes read kind-keyed, and on
  every error path (finally).
- A crash inside the window heals on the next DatabaseConnection open —
  schema.sql re-applies CREATE INDEX IF NOT EXISTS, same recovery as the FTS
  bulk-load pattern this mirrors.
- Concurrent readers (a daemon serving the project mid-index) stay correct;
  target/kind-keyed reads degrade to scans only for the window's duration.

dubbo (4,402 files): persists 4.0s -> 3.0s, fresh init 11.9s -> ~11.1s,
graph byte-identical. excalidraw (below the gate): untouched, byte-identical.
Recreation cost ~250ms, logged under CODEGRAPH_SYNTH_TIMINGS as
edge-index-recreate. Suite green (2444).

cf38ef65af perf(synthesis): fan dynamic-dispatch passes across the resolver pool, byte-identical graphs (#1321)
The ~36 independent synthesis passes (callback/event/framework wiring) ran
sequentially on the indexer's main thread — 2.0s of a 4,402-file Java repo's
index, and the stage where kernel-class repos die (#1212). They now live in
an explicit registry (SYNTH_PASSES) and, when the resolver pool is alive
(>=150k-ref repos), fan out across its read-only workers: dubbo synthesis
2,024ms -> ~900ms (-55%), total fresh init 13.5s -> 11.9s. Graphs verified
byte-for-byte identical on both the pool path (dubbo) and the sequential
path (excalidraw).

Why this is safe: no pass's edges persist until the ordered merge, so every
pass sees the same committed post-resolution DB state in either mode, and
results merge in registry order regardless of completion order — the
first-seen dedup is unchanged. The pool now survives through synthesis
(destroy moved after it) instead of being torn down moments before the one
stage that could reuse it.

Robustness: a pass that fails on a worker (crash, OOM) is retried on the
main thread — a synthesizer blow-up now costs one worker instead of the
whole index, which is half the #1212 story on very large repos.

Also: ref-row cleanup deletes now run as one transaction with a cached
statement instead of one implicit commit per 500-row chunk (mechanically
fewer WAL commits; matters most on HDD-class storage). A set-based rewrite
of failed-ref parking was tried, measured ~zero on NVMe, and dropped — the
remaining persist cost is edge-index B-tree maintenance, not statement
dispatch.

SYNTH_PROGRESS_STEPS now derives from the registry (passes + fixed marks);
the pin test counts registry entries plus literal __mark sites.

Suite green (2444). Sequential-path timing unchanged on excalidraw.

a2f3c31a97 perf(resolution): defer checkpoints and double-buffer persist during resolution, byte-identical graphs (#1320)
Fresh init on a 4,402-file Java repo (dubbo): 18.2s -> 13.5s (-26%), with
the resolution phase going 12.6s -> 7.9s (-38%). Graphs verified
byte-identical on both the pool path (dubbo) and the sequential path
(excalidraw).

Two changes:

1. The fastInit+pool path restored WAL for the resolver workers but left
   wal_autocheckpoint at its default, so the persist loop inline-checkpointed
   hot pages all phase long (#1231's pathology inside resolution — measured
   at 58% of resolution wall). Checkpointing is now deferred behind the
   bounded valve and folded once at maintenance, mirroring the deferWal path.

2. The resolution loop is double-buffered: batch k+1 is prefetched (OFFSET
   past batch k's still-pending rows, under an explicit ORDER BY rowid) and
   fanned out across the pool while batch k's ref cleanup runs on the main
   thread. Batch settle-waits dropped 2572ms -> 117ms.

Correctness invariant found by the byte-identical gate and now documented in
the loop: batch k+1's resolution READS batch k's edges (resolveMethodOnType
walks supertype chains over extends/implements edges that resolution itself
inserts), so edges must persist BEFORE the next batch fans out; only the ref
cleanup overlaps.

Also extends the CODEGRAPH_SYNTH_TIMINGS instrumentation with phase labels
(grammar-init, parse-loop, fts-rebuild, resolver-reinit, resolution,
callback-synthesis) and pool timings (worker open/resolve, per-batch mode,
persist), so the next profile is one env var away.

Suite green (2444). Sync path timings unchanged. Pool floor re-validated:
forced-on at 40k refs is still net-slower, so the 150k threshold stands.

c472cfb52e fix(resolution): literal-receiver builtins and nested locals stop fabricating call edges (#1317)
", ".join(sorted(x)) resolved by bare name to a project function named
join — one nested inside a DIFFERENT function, so scope alone rules the
edge out. Both defects from #1230, fixed independently:

1. Extraction: a member call on a LITERAL receiver (string, number,
   collection, regex — across grammars) emits no call ref at all. A
   literal's methods are the language's builtins, never project
   symbols; the bare-name fallback let them exact-match any same-named
   project function. Silent miss, never a wrong edge.

2. Resolution: matchByExactName filters out candidates nested inside a
   same-file FUNCTION container unless the ref originates within that
   container's line range. Class members (parent is a class-like node),
   top-level symbols, and C++ namespace prefixes (no parent node) are
   untouched.

requests re-index: byte-identical (813 calls edges). excalidraw: -27
edges, all literal-receiver refs by construction. The issue's repro is
pinned: join has exactly one caller (format_fields), report_missing
has zero project callees.

41c2029798 fix(go): field-chain calls resolve via validated type inference, never bare-name guessing (#1316)
target.conn.Exec("insert") with `conn *sql.DB` emitted a BARE `Exec`
ref (the receiver chain was dropped for non-identifier receivers), and
exact-match then bound it to the only local `Exec` — an unrelated
interface's method — fabricating an internal dependency (#1276).

Extraction now keeps Go 2-hop selector chains (`base.field.Method`),
and a dedicated matcher resolves them EXCLUSIVELY via two inference
hops: base's type from the enclosing scope (#1108 machinery), field's
declared type from the struct's own declaration lines (comment-
stripped, per-line — chi's "the tree router" doc comment otherwise
donates a phantom type). resolveMethodOnType validates the target.
Package-qualified field types are followed only when the package is
in-module — `handler http.Handler` must not bind a same-named local
decoy. Failure at any hop leaves the ref unresolved: chained Go
receivers never fall through to the bare-name strategies (they were
never emitted before, so no prior recall depends on that path).

chi before/after: node count stable (1,181); 8 correct field-chain
edges gained (mx.tree.FindRoute/InsertRoute/routes, validated,
including the unexported `node` type); the removed edges are the
prior bare-name guesses on external receivers.

2ec877b08c fix(resolution): calls through an imported singleton resolve to the method (#1315)
reproStore.notifyJoinGuildStatus() after `import { reproStore }`
resolved its calls edge to the exported CONSTANT (resolvedBy:'import'),
while the identical same-file call resolved to the method via
local-variable receiver inference (#1108) — so `callers <method>`
missed every cross-file use and a widely-used method could look
unused (#1292).

resolveViaImport's member-descend now handles imported VALUES alongside
the #825 static-member case: when the base resolves to a
constant/variable, the value's type is inferred from ITS OWN
declaration lines in the exporting file (the shared #1108 pattern
table: `= new T(...)` initializers and type annotations) and the member
is resolved AND VALIDATED on that type via resolveMethodOnType. A
failed inference or validation keeps the existing constant edge —
never a fabricated one. Calls only; plain member reads still reference
the value.

excalidraw control: byte-identical graph (10,653 nodes / 19,483 calls
edges before and after).

e1f339f732 fix(go): require URL-shaped paths for route detection (#1308)
cache.Put("a", 1), store.Get("config", out), bus.Handle("user.created",
h) — any verb-named method with a string first arg — were indexed as
HTTP routes (38 of 82 route nodes were false positives on the
reporter's 200 KLOC Go codebase). A registration's first argument must
now start with "/" (every router style), or be a Go 1.22
"METHOD /path" mux pattern on Handle/HandleFunc — which now also
extracts the real method instead of ANY.

Validated on go-chi/chi (212 real routes retained, all path-shaped)
and golang/groupcache (0 route nodes).

5736e24bb6 perf(index): faster fresh indexing + parallel reference resolution, byte-identical graphs (#1305)
* perf(index): ~34% faster fresh indexing, byte-identical graphs

Profiling a fresh init on a medium TS repo (excalidraw, 657 files) showed
the main thread as the critical path: per-row SQLite statement calls,
repeated import-resolution walks, and per-row FTS trigger firings, with
the parse workers ~75% idle behind it. This lands the semantics-preserving
tranche of fixes:

- Multi-row batched INSERTs (nodes/edges/unresolved refs/name segments)
  behind cached per-batch-size prepared statements; row order preserved,
  so rowid-based resolution determinism (#1015) is unchanged.
- storeFileBundle: one transaction per file instead of four; nested
  transaction() calls now flatten (BEGIN-in-BEGIN previously threw, so no
  caller depended on nested rollback).
- Dedicated store-writer thread for the fresh-DB bulk path (bundles
  applied in file order on a single writer connection; main thread does
  no DB work during the parse loop). Kill switch: CODEGRAPH_NO_STORE_WORKER=1.
- Bulk FTS mode: drop the nodes_fts sync triggers during the bulk load,
  rebuild once at the end; crash inside the window self-heals on the
  next open.
- Per-context memos for resolveImportPath/findExportedSymbol + a per-file
  exported-symbol index, invalidated exactly where clearCaches() already
  resets the resolver's own caches.
- Fast-init on completely fresh DBs (journal in memory, no fsync until
  the index completes; interrupted init re-runs from scratch). Kill
  switch: CODEGRAPH_NO_FAST_INIT=1.
- MaybeYield returns undefined on the not-due path so per-ref yield
  checks stop paying a promise + microtask hop each.
- Parse pool prewarm for bulk indexing; compile-cache enabled at CLI and
  worker entry points.

Excalidraw fresh init: 5.11s -> 3.36s median (n=5, warm cache, M-series).
Graph dumps byte-identical across init, re-index, and sync paths; full
suite green (2403 passed).

* perf(resolution): parallel reference resolution with canonical admission

Fan resolution batches across a pool of read-only worker threads, each
hosting a full ReferenceResolver over its own SQLite connection; results
are admitted on the main thread in chunk order, so edge insertion order,
row cleanup, failure parking, and deferred post-pass queues are exactly
the sequence the single-threaded loop produces. Per-ref inputs match the
baseline because the sequential path already resolves each batch against
the state committed BEFORE that batch.

Validated byte-identical on excalidraw (pool forced on) and apache/dubbo
(4,048 Java files): dubbo full index 39s -> 19s (2.05x) with identical
graph dumps (91,495 nodes / 223,953 edges).

The pool only engages when total pending refs clear a threshold (default
150k, CODEGRAPH_PARALLEL_RESOLVE_MIN to tune, CODEGRAPH_NO_PARALLEL_RESOLVE=1
to disable): measured on a ~58k-ref repo the workers' boot CPU contends
with resolution on the same cores and makes indexing slower, so small
repos keep the sequential path. When fast-init left the DB in
memory-journal mode, WAL is restored before resolution only when the pool
will run (readers + rollback-journal writers don't mix).

Also: sqlite adapter readOnly open support.

TreeCursor spine rewrite of the body walker was built, measured neutral
on real repos and equal in a 20k-child microbench (web-tree-sitter's
namedChild(i) is not quadratic in this binding), and rejected — per-node
JS<->WASM marshaling is the floor, which a traversal swap cannot remove.

246aee8373 fix(ui): within-pass progress for the C fn-pointer linking pass (#1300)
Follow-up to #1299: the per-pass bar still parked on one number while a
single long pass ran — on C-heavy repos that's the fn-pointer dispatch
pass, which sweeps every C/C++ file four times (typedefs, registrations,
field propagation, dispatch sites) and dominates the linking phase.

The pass now reports a real fraction of its dominant work
(scannedFiles / files×4, at the same per-16-files cadence as its
cooperative yield), and the orchestrator surfaces instrumented passes'
fractions as fractional steps, throttled to whole-percent movement so
the UI message volume stays bounded. The mechanism is opt-in per pass —
any synthesizer that a real repo shows parking the bar can adopt the
same callback.

Verified on the 1,342-file C repo from the report: the linking bar now
moves through 88→89→90 where it previously sat at 88 for the whole
pass; graph byte-identical (50,520 nodes / 148,232 edges).

ad5300a601 fix(ui): show synthesis as a 'Linking dynamic dispatch' phase; mute node:sqlite warning spam (#1299)
Two first-run UX bugs surfaced by indexing a real 1,342-file C repo:

1. After 'Resolving refs' hit 100%, the ~40 dynamic-dispatch synthesis
   passes ran with no progress surface, so the bar sat frozen at 100%
   long enough to read as a hang (the C fn-pointer pass alone can hold
   for a while on C-heavy repos). Synthesis now reports per-pass
   progress through a new 'linking' IndexProgress phase, rendered as
   'Linking dynamic dispatch'. The step total is pinned by a test to
   the synthesizer's actual __mark() count so adding a pass without
   bumping it fails loudly.

2. node:sqlite's ExperimentalWarning is emitted once per THREAD, so the
   main process plus every parse worker printed it mid-index,
   interleaved with the progress UI. All launch paths now pass
   --disable-warning=ExperimentalWarning: both bundle launchers, the
   Windows npm-shim invocation, and the CLI self-relaunch
   (NODE_RUNTIME_FLAGS, deliberately excluded from the re-exec gate so
   an older installed launcher never triggers a pointless re-exec, and
   version-gated off nodes older than the flag).

Verified end-to-end on the same repo: zero warnings, live linking bar,
byte-identical graph (50,520 nodes / 148,232 edges). Full suite green.

e871c49a31 fix(resolution): clean up processed refs by row id so batch boundaries can't drop sibling call sites (#1269) (#1270)
Post-batch cleanup deleted resolved refs (and parked failed ones) by
(from_node_id, reference_name, reference_kind) — no line/col. When one
caller had several call sites to the same callee and a batch boundary
split them, the first batch's cleanup removed every row with that key,
including later-batch siblings that were never attempted — their edges
were silently never created. On nlohmann/json this ate 422 real call
edges (write_cbor's 38 to_char_type calls indexed as 11).

Refs loaded from unresolved_refs now carry their row id through
resolution, and all three persist paths (sync resolveAndPersist, the
yielding retry pass, the batched drain loop) delete / mark-failed by
exactly that id. The key-tuple methods remain only as the fallback for
hand-built refs from the public API. Failed-parking gains the same
precision: outcome can differ per call site (receiver inference reads
the ref's line), so a sibling must not inherit another row's failure.

Also untracks the zz-scratch local test files that slipped into #1268
and gitignores the pattern.

Validation: red-green regression test (5 sites, batch size 2 — old code
kept 2 edges, fix keeps 5); nlohmann/json re-index is a strict superset
of the previous edge set (0 lost, 422 recovered, spot-checked against
source).

6103f5e228 fix(cpp): resolve explicit operator calls (a.operator+(b)) to the operator method (#1268)
* fix(cpp): resolve explicit operator calls (a.operator+(b)) to the operator method (#1247)

tree-sitter-cpp can't parse an operator_name in field position: the
call_expression carries `function: <receiver>` plus an ERROR child
wrapping the operator_name instead of a field_expression callee, so the
extractor emitted a calls ref named just the receiver (`a`) and the edge
never resolved — while the operator method itself indexed fine.

Two-part fix, scoped to the explicit call form (infix `a + b` / `a[i]`
need receiver type inference and are tracked in #1258):

- extraction: recover the operator_name from the ERROR child and emit
  `<receiver>.operator+` (`->` receivers normalized, `this->` emits the
  bare name), like any other member call
- resolution: matchMethodCall's dot pattern now admits an operator
  method part (cpp-gated; symbol chars failed the \w match), so
  receiver-type inference + resolveMethodOnType validate the target —
  a same-named operator on an unrelated class can't capture the edge

* fix(cpp): harden explicit operator-call recovery against real-world shapes (#1247)

Validated on nlohmann/json (dozens of explicit operator[] / operator* /
operator< call sites). Two refinements the synthetic fixtures missed:

- normalize spaced call-site operator names (`it.operator * ()`,
  `other.operator < (*this)`) to the compact form definitions index as
- drop the ref for a complex receiver (`obj()->operator+`, member chains
  ending in a call) instead of emitting a bare operator name: exact-name
  fallback GUESSED among unrelated same-named operators (linked a
  std::map operator[] call to an in-repo operator[]) — silent miss,
  never a wrong edge

9d0cd3a7d1 fix(sync): resolve cross-file refs when an edit adds or removes the satisfying symbol (#1240) (#1249)
* chore: ignore .kommandr/ directory

* fix(sync): resolve cross-file refs when an edit adds or removes the satisfying symbol (#1240)

Incremental sync scoped reference resolution to the changed files' own
refs, and a completed pass deleted every ref it failed to resolve — so
a symbol change in one file could never repair references in UNCHANGED
files, in either direction, until a full re-index:

- New-export case: a.ts imports/calls `greet` before b.ts defines it.
  The failed refs were deleted at index time; when b.ts later gained
  `greet`, nothing revisited a.ts — the calls/imports edges stayed
  missing while status reported a clean index.
- Removal case: when a re-index (or file deletion) dropped a symbol,
  the incoming edges cascade-deleted and the callers — whose resolved
  refs had been consumed — never got a chance to rebind to an
  alternative definition or reconnect when the symbol returned.

Fix, sharing one lifecycle:

- Schema v8: unresolved_refs gains status ('pending'/'failed') and
  name_tail (last dotted segment, so `h.greet` is findable by `greet`).
  Both resolver persist paths now park unresolvable refs as failed
  instead of deleting them. All pending-work readers (batched drain,
  non-progress guard, #1187 orphan sweep, status pendingRefs) filter to
  pending, preserving their invariants and keeping status honest.
- Sync retry: after scoped resolution, failed refs whose name tail
  matches a symbol name now present in the changed files are re-resolved
  through a per-ref-yielding path (watchdog-safe, #1091 class). Names
  matching >500 failed refs are skipped as external/builtin noise (#999
  rationale).
- Removal side: createEdges stamps each resolution edge with its
  originating reference (metadata.refName, + refKind when kind promotion
  rewrote it). When the #899 restore misses a target or sync deletes a
  file, the dropped edge is resurrected as exactly that ref — re-resolved
  in the same sync (rebinding to an alternative definition) or parked
  failed until the symbol reappears. Edges without the stamp (pre-upgrade,
  synthesized) still drop silently: reconstructing from the target's plain
  name would strip receiver context and risk a rebind a full re-index
  would never make.
- Pure-removal syncs clear resolver caches so a long-lived daemon can't
  resolve resurrected refs against the pre-removal graph.

Validated: issue repro now yields a graph byte-identical to a full
re-index; move/remove-readd/file-deletion scenarios all rebind or heal;
baseline-vs-new A/B on express and gin shows identical node/edge counts
and no timing regression (DB grows ~25% from the parked ref rows — pure
cache, reset by any full re-index). 8 regression tests added.

Fixes #1240

e76a355df5 fix(resolution): gate closure-collection synthesis to Swift/Kotlin and de-quadratic its line accounting (#1235) (#1237)
closureCollectionEdges scanned every method/function node in every
language, but its dispatcher patterns ({ $0( / { it( ) are Swift/Kotlin
trailing-closure syntax — on PHP/JS repos the pass can never emit an
edge, yet .push(/.add( fired its append gate on nearly every function.
Per match it computed the line via src.slice(0, idx).split('\n'), which
is O(source) per match and goes quadratic on match-dense generated
functions (two-byte content roughly doubles it). On a 12,860-file
PHP/JS app that was 20+ minutes of the "Resolving refs" tail — frozen
at 97% — and a #850 watchdog kill; profiled on CRMEB it was 127s of a
166s index for zero edges.

- Skip nodes whose language isn't swift/kotlin before any file I/O.
- makeLineAt(): lazy newline index + binary search, shared with the
  emitter passes' per-file lineOf.
- Yield every 256 regex matches inside the scan's match loops so a
  single pathological function can't starve the watchdog.

CRMEB (ThinkPHP, 2,913 files): 166.8s -> 72.7s, graph byte-identical.
Alamofire: closure-collection edges byte-identical (9 edges, 4 fields).
Drupal core control: graph byte-identical.

a3f90089e8 fix(indexing): bounded-memory yielding pipeline tail + daemon session fixes (#1212) (#1226)
Large-codebase indexing died at the end of "Resolving refs" two ways:
watchdog kills of healthy work (24k-file Java on Windows, #1212 — third
iteration of the #1091/#1122 class) and hard OOMs (Linux kernel scale,
where v1.3.0 could not complete at any watchdog setting). Root causes:
~31 of 37 dynamic-edge synthesis passes ran start-to-finish with no
yield points, several materialized whole-graph snapshots (kotlin
expect/actual opened with getAllNodes() — 2M nodes in one array; the
C fn-pointer pass retained every C file's contents twice plus every
function node), and the post-index WAL checkpoint ran minutes of
synchronous IO on the main thread, killing even a successful index at
the finish line.

The pipeline tail now follows the same discipline as the rest: never
hold O(graph) in the heap, yield everywhere.

- All synthesis passes stream node-kind scans (cursors, not arrays) and
  yield on time-budgeted checkpoints; language gates skip passes whose
  filters a project's file languages provably can't satisfy.
- kotlin expect/actual filters SQL-side; c-fnptr caches are LRU-bounded,
  units stream one file at a time, and the all-functions array +
  write-only id map are gone; spring reads each .java once, not twice.
- runMaintenance moved to a worker thread (own SQLite connection);
  per-file store commits chunk with yields behind a serialized flush
  chain (preserving #1015 file-order determinism); resolver warm-up
  streams the DISTINCT name set; resolution batch-tail and merged-edge
  inserts run in bounded sub-transactions.
- Daemon: fixed a socket-handoff race that could leave a fresh MCP
  session permanently silent (client-hello tail unshifted into a
  flowing stream with zero listeners — the long-standing #662 test
  flake was this real bug); first tool call no longer queues behind
  the query pool's cold start (pool.ready gate).

Validation: Linux kernel (70,129 files, 2.05M nodes, 6.4M edges) fully
indexes in 27m8s on a 2-core/6GB container at default heap + default
watchdog; llvm-project (180k files) completes under 1GB RSS including
kill-and-sync recovery; synthesized-edge and full-graph parity are
byte-identical vs baseline on elasticsearch/redis/vim; the ex-flaky
daemon test passed 25/25 under load. Env-gated diagnostics kept:
CODEGRAPH_SYNTH_TIMINGS pass/phase timings, CODEGRAPH_MCP_DEBUG hop
tracing. Design record: docs/design/main-thread-stall-followup.md.

625b4fe921 fix(resolution): stop per-call config-key scan that made large Java/Kotlin (Spring) indexes take ~1h (#1180) (#1210)
On a large Java/Kotlin Spring monorepo, reference resolution — not extraction —
dominated a full index (Spring Boot's ~9,650-file tree: extraction 62s,
resolution ~26min). The Spring framework resolver ran an uncached
getNodesByKind('constant') full scan + canonicalConfigKey() filter for EVERY
dotted `calls` ref (every list.add(), builder.build(), receiver.method()),
because the config-key branch gated only on "dotted java/kotlin", not on ref
kind. With ~1,100 constant nodes × ~200k dotted calls that is ~200M wasted
row-fetches/allocations.

Fixes, one theme — config-key constants bind config `references`, never `calls`:
- frameworks/java.ts: gate the Spring config-key branch on
  referenceKind === 'references' (what @Value/@ConfigurationProperties emit) so
  the `calls` flood skips the scan.
- name-matcher.ts: a `calls` ref no longer resolves to a yaml/properties config
  node via matchByQualifiedName (service.process() vs the yaml key
  service.process) — a wrong edge that also hid the real callee; it now falls
  through to method resolution.
- resolution/index.ts: cache getNodesByKind in the resolver context (same
  lifetime as nameCache). Fixes the same uncached-per-ref scan in the Drupal
  hook_ resolver and is defense-in-depth for the Spring :prefix branch.

Measured (Spring Boot): resolution 269s→16.5s on a 4.3k-file module (16×) and
~26min→44.7s on the full 9.6k-file tree (~35×); graph byte-identical, full suite
passes. Adds a regression test (same key, two ref kinds, opposite outcomes).

4c15f84aa4 fix(resolution): sweep orphaned unresolved refs so an interrupted index heals on sync (#1187) (#1191)
An indexing run killed mid-"Resolving refs" (crash, Ctrl-C, the #1122
watchdog kill) left the refs it never reached parked in unresolved_refs.
The git-scoped sync fast path only re-resolves changed files' refs, so
those files' call edges were missing permanently — a too-small blast
radius clustering by package/module (the #1187 field report: 3 of 10
caller files for a Spring @Resource-injected method) — until a full
re-index.

- sync() now sweeps leftover unresolved refs with the batched resolver
  after its scoped pass, including on no-change syncs, so a bare
  `codegraph sync` recovers a wedged index (and heals pre-fix indexes
  on the first post-upgrade sync)
- the scoped pass deletes unresolvable rows too (parity with the
  batched path), making "rows at rest" a sound orphan signal
- drop the batched loop's early break that abandoned all later batches
  when one batch was all-unresolvable (its rows WERE consumed — that
  early stop could orphan the rest of the table at init)
- surface the state: `codegraph status` warns, `status --json` gains
  index.pendingRefs, and MCP codegraph_status tells agents the blast
  radius is incomplete until the next sync

Verified end-to-end on a 2,414-file synthetic Spring repo: SIGKILL
mid-resolution reproduces the reporter's exact 3-of-10-callers state;
a bare sync now heals it to 10/10 with the edge count converging to
the clean-init total; a healthy-index sync stays a no-op.

99152212a9 feat(extraction): add ArkTS language support with ArkUI dispatch bridges (#396, #512, #890 via #648) (#1186)
Adds ArkTS (.ets, HarmonyOS/OpenHarmony) as a first-class language:
full TypeScript-grade extraction via the harmony-contrib tree-sitter
grammar (MIT, vendored byte-identical from the tree-sitter-arkts 0.2.0
npm tarball), plus the ArkUI constructs that make HarmonyOS apps
traceable:

- @Component/@ComponentV2 structs with decorators from both grammar
  positions; members extract as class members with qualified names.
- build() component trees: child instantiation edges via
  arkui_component_expression, no synthesizer needed.
- Attribute chains emitted dot-prefixed and resolved ONLY against
  @Extend/@Styles/@AnimatableExtend/@Builder helpers (unique-or-drop) —
  bare-name fallthrough produced 36,840 wrong edges (17% of calls) on
  the OpenHarmony samples monorepo. All four grammar chain shapes
  handled, including the detached-chain forms.
- .onClick(this.handler) method-reference bindings.
- ohpm workspace modules: bare imports follow oh-package.json5 file:
  deps (ambiguous names dropped), honoring each module's main entry —
  which also lets .ts consumers resolve .ets modules.
- ArkUI dynamic-dispatch bridges, all provenance:'heuristic' with
  wiring-site metadata: assignment-gated state->build() re-render
  (V1 @State family + V2 @Local/@Provider/@Consumer),
  @ohos.events.emitter emit->subscriber pairing on static event keys
  (numeric ids same-file, named constants same-module, fan-out capped),
  and router.pushUrl literal urls -> the target page's @Entry struct.
- $r/$rawfile resource intrinsics treated as built-ins; arkts joins the
  web language family, value-reference edges, re-export chase, and the
  other TS-applicable gates.

Also ships a language-agnostic index-completeness guard: indexAll
stamps index_state (indexing -> complete/partial/failed), reconciles
discovered vs accounted files (a loaded run silently dropped 37 files),
and codegraph status surfaces truncated/partial indexes in human and
--json output.

Validated on HarmoneyOpenEye (82 files), CoolMallArkTS (528, modular
ohpm + ArkUI V2), and openharmony/applications_app_samples (11,693
files, 202,890 nodes stable across re-index, attribute false-positive
audit 36,840 -> 588 residual all-plausible). Supersedes PRs #656 and
#988 with credit — both informed this implementation.

  cross-directory output edges explained: 528 local-module + 254
  remote-state + 7 checker-artifact false alarms under deprecated/);
  coverage 66.4% -> 69.1%.

- provider aliases: provider "aws" { alias = "east" } is addressed as
  provider.aws.east so aliased and default configurations stop
  colliding; provider = aws.east on a resource/data block (and the
  values of a module's providers map) reference the selected
  configuration, resolved same-directory first then up the module tree
  — the one construct Terraform genuinely inherits from parents. The
  selection is no longer misread as a resource reference (aws.east).

- moved/import/removed blocks reference the resource addresses they
  name (anchored to the file node — no phantom symbols), so a
  refactor's paper trail joins the graph; check-assert conditions
  contribute their references while check-scoped data blocks keep
  indexing as before. Scoped module candidates are suppressed there:
  module.a.aws_x.b names a resource inside a module instance, not an
  output. +91 edges on cloud-foundation-fabric's moved-heavy stages.

Also fixes a latent test bug from #1173: cg.getNodeById is not public
API (cg.getNode is) — it only passed because the asserted edge list was
empty.

6c24f4bddf feat(extraction): add Terraform/OpenTofu language support with module-boundary bridging (#83, #310, #648 — carries #706) (#1173)
* feat(extraction): add Terraform and OpenTofu language support

Index .tf, .tfvars, and .tofu files via the tree-sitter-terraform dialect
of HCL (vendored from @tree-sitter-grammars/tree-sitter-hcl, Apache-2.0).

Symbols extracted:
- resource / data  → class  (qualified "type.name" / "data.type.name")
- module           → module (qualified "module.name")
- variable         → variable (qualified "var.name")
- output           → variable (qualified "output.name")
- provider         → namespace
- locals           → constant per attribute (qualified "local.key")

References resolved cross-file:
- var.X, local.X, module.M[.out], data.T.N[.attr], <type>.<name>[.attr]
- built-ins skipped: each.*, count.*, self.*, path.*, terraform.workspace

The Terraform framework resolver disambiguates same-named candidates
across modules by preferring the one in the same directory as the
reference site, then by closest common-ancestor path, falling back to
the generic name matcher only when neither applies.

Validated on two Terraform monorepos (277 and 470 .tf files): indexing
runs in 1.3s and 2.4s respectively, query latency stays under 200ms,
and cross-module references resolve to the correct module 100% of the
time on inspected samples.

18 new extraction tests; full suite 1146/1148 green (2 pre-existing
flaky skips, 0 regressions).

* feat(terraform): bridge the module boundary and enforce directory scoping

Builds on #706. The module declaration was a dead end: module.M.out
resolved to the declaration and stopped, module inputs never reached the
child module's variables, and impact could not cross the boundary — on
real multi-module repos that breaks the core blast-radius question
("what breaks upstream if I change this module's variable/output").

- module blocks now wire across the boundary through :-scoped refs only
  the Terraform resolver understands: module.M:var.<input> → the child's
  variable node, module.M:output.<o> → the child's output node (emitted
  alongside the module.M declaration ref), and module.M:file → the local
  source directory's entry file (imports). Registry/git sources emit no
  file ref and resolve nothing — an out-of-repo module stays a visible
  boundary instead of a guess.
- .tfvars top-level assignments reference the variable they set, walking
  up to the nearest ancestor directory (envs/prod.tfvars → root vars).
- Resolution now enforces Terraform's real scoping: same-directory only
  (no cross-module fallback by common path prefix, no single-candidate
  anywhere-in-tree binding), and terraform refs never fall through to
  the generic name matcher — var.X can never legally bind outside its
  module directory, so the fallback could only add wrong edges.

a0208feaac feat(extraction): index Erlang escripts and OTP app resource files (#635, #648) (#1169)
escripts (.escript) index like any module — the ELP grammar has a
first-class shebang node, so no source transform is needed; main/1 and its
helpers get full function/call extraction.

OTP application resource files (<app>.app.src and compiled <app>.app) join
the graph as Erlang terms the grammar parses natively. They route by full
suffix (their last-dot extension, .src, is far too generic for the
extension map). The application tuple yields structure: {mod, {Mod, _}}
links the app to its callback module — the app's entry point — and
{applications, [...]} / {included_applications, [...]} connect umbrella
sibling apps, resolving through the OTP app-name == module-name convention;
kernel/stdlib and other out-of-repo apps stay unresolved.

App-file refs resolve only ever to MODULES: validation on emqx caught the
ssl OTP-app dependency resolving to a test helper FUNCTION named ssl (the
same defect class as the earlier -behaviour gate), so the matchReference
module-only gate now covers every ref an .app/.app.src file emits.

Validated on emqx: 2 app.src + 6 escripts indexed, entry-module and
umbrella-dependency edges all namespace-targeted post-gate, escript
functions extracted; a stray legacy/module.src stays unknown.

2217a35943 feat(resolution): Erlang behaviour-callback dispatch synthesizer (#635, #648) (#1166)
Bridges the OTP callback boundary: a framework call through a variable
module — cowboy's Handler:init / Middleware:execute folds, a plugin
manager's Mod:callback(...) — now links to the repo's implementers of the
behaviour declaring that callback, so codegraph_explore connects flows
end-to-end across behaviour dispatch instead of stopping at it.

Precision gates: the callback arity must match the site, exactly one
in-repo behaviour may declare that (name, arity) — a collision bails
(cowboy's init/2 is declared by five handler-flavored behaviours and
correctly stays silent) — the implementer must export the callback, and
above the fan-out cap the site is skipped entirely (ejabberd's gen_mod
with ~230 implementers stays a visibly dynamic boundary). Behaviour
discovery scans -callback declarations in every module so implementer-less
behaviours still gate ambiguity. Edges carry provenance:'heuristic' with
synthesizedBy:'erlang-behaviour' and the wiring site, rendered as dynamic
dispatch in explore.

Validated per the dispatch-family playbook: cowboy 38 edges (middleware
chain, stream-handler folds, sub-protocol upgrade), ejabberd 598, emqx 843;
36/36 sampled edges precise (target declares the via-behaviour and exports
the callback); node counts unchanged; ~1.4s added on emqx's 2,273 files;
zero-control clean. The cowboy request flow connects in one explore call.

Includes an Erlang comment stripper (%-comments, string/atom/$-char aware)
for the dispatch-site scans.

6511722250 feat(extraction): add Erlang language support (.erl/.hrl) (#635, #648) (#1165)
Vendored WhatsApp/tree-sitter-erlang 0.19 (the ELP grammar, ABI 14) with an
Erlang-shaped extractor: multi-clause/multi-arity functions merged into one
symbol, -spec signatures, records with fields, -type/-opaque aliases, -define
macros, -include/-include_lib file edges, and -export-driven visibility.

Modules wrap in a namespace so remote mod:fn(...) calls resolve through the
existing qualified-name matcher as mod::fn with zero resolver changes.
-behaviour declarations link to the behaviour module — gated to namespace
targets only (bare-name fallthrough linked -behaviour(supervisor) to an
unrelated macro constant on emqx). OTP indirection with static targets is
followed: spawn/apply/proc_lib/timer/rpc MFA-argument callees, and
gen_server:call/cast(?MODULE | ?SERVER) to the module's own
handle_call/handle_cast. Var-module dispatch and message sends stay
deliberately unlinked. codegraph_explore also normalizes Erlang-native query
spelling (mod:fn/3, init/2) so named symbols resolve as typed.

Benchmarked on cowboy (189 files), ejabberd (414), emqx (2,447): extraction
PASS on all three; with-codegraph arms reached 2/2/0 file Reads vs 10/5+/19
without, fastest on the largest repo.

source format (free format via a scanner wide-mode sentinel).

Grammar: vendored wasm built from a patched yutaro-sakamoto/
tree-sitter-cobol (EXEC blocks as an external-scanner token, copybook
fragment entry point, single-quote continuation, COPY REPLACING
pseudo-text, NOT=, CALL GIVING, ENTRY, FREE, bitwise ops, abbreviated
relations, COBOL-2002 usages, and more). Patch + provenance + upstream
PR draft in docs/grammars/. Parse health: AWS CardDemo 43/44 native
(upstream: 9/31), 44/44 through preParse; copybooks 28/29; CobolCraft
free-format 17/17 (upstream: 0); NIST COBOL85 unchanged at 373/382.

Copybook members resolve to files like C includes (basename index,
name-matcher short-circuit so compiler-supplied members stay honestly
unresolved): CardDemo imports 5 -> 285. Impact proof: ACCT-CURR-BAL
(CVACT01Y copybook) surfaces its 4 writer programs cross-file.

81cb59a86e fix(resolution): yield per ref and cache hot per-ref work so the watchdog can't kill a valid index (#1122) (#1137)
The #850 liveness watchdog was killing valid `codegraph init`/`index` runs
at "Resolving refs 0-2%" on large collision-heavy repos (18-25K-file Java
monorepos on slower hardware). #1105's cooperative yielding assumed a
500-ref sub-chunk is always cheap, but per-ref cost is unbounded: a
colliding method name (`execute`, `process`, ...) whose candidate set
misses the 5,000-entry name LRU re-fetches every same-named row
(unbounded SELECT + materialization, measured 8.8ms at just 4K collisions
on an M4 — linear in collision count), and receiver-type inference
re-split the whole source file per ref (~20% of total index CPU). A dense
pocket multiplied that past the 60s window and the heartbeat starved.

Three guards, no behavior change:
- resolveBatchYielding checkpoints after EVERY ref (maybeYield is a ~ns
  time check when under budget), so a slow pocket can never run more than
  one ref past the yield budget.
- resolveMethodOnType's ref-independent candidate filter is memoized per
  (language, Type::method) on the resolver context; per-ref
  disambiguation (import FQN #314, call-site file #1079) stays outside
  the memo.
- Receiver inference reads lines through a per-file LRU (shared and C++
  inferrers), and skips generated/minified lines >10K chars instead of
  regex-scanning them per ref.

Measured on a 4,028-file synthetic Java bank repo (392K refs): mid-loop
max event-loop stall 1528ms -> 546ms under cache thrash, total init
250.9s -> 96.8s at default config.

e53968cae8 fix(resolution): gate the Lua/Luau annotation pattern against method-call self-match (#1124) (#1131)
Lua method-call syntax (lg:Log()) is byte-identical to the Luau type-annotation
shape (lg: Logger), and the receiver-type scan starts on the call's own line —
so any PascalCase method call self-matched as "type = Log" before the scan
reached the real declaration, silently dropping the calls edge whenever two or
more classes shared a method name.

The annotation pattern now rejects a capture followed by any of Lua's three
call forms; its leading [\w.] lookahead alternative prevents backtracking from
shrinking the capture to dodge the gate. Gated rather than dropped: the pattern
is the only type source for Luau typed params and annotated locals whose
initializer isn't T.new().

cf86fe8198 fix(resolution): extend typed-parameter receiver inference to Rust/Go/Dart/PHP (#1125) (#1130)
Completes the #1125 fix. The same typed-parameter gap fixed for TS/JS existed
in every other language whose localReceiverTypePatterns only matched
keyword-anchored locals (let/var/:=/= new) and never the bare parameter form:

- Rust: the `:`-annotation pattern required `let`, so `fn use(lg: &Logger)`
  didn't match. Dropped the `let` anchor (still covers `let lg: Logger`),
  keeping the `&?mut?` handling — now covers params and closures `|lg: T|`.
- Go: only `lg := T{}` / `var lg T` matched; a parameter/method-receiver
  `func use(lg Logger)` / `func (l Logger) M()` (name-before-type, no keyword)
  didn't. Added a PascalCase-guarded `ident Type` pattern — the guard plus the
  existing enclosing-scope bound (excludes package-level struct fields) keep
  the keyword-free shape from matching unrelated pairs.
- Dart: the type-before-name pattern's trailing `[=;]` missed a parameter's
  `)`/`,`. Widened to `[=;,)]`, mirroring Java/C#.
- PHP: only `$lg = new T` matched; a typed param `function use(Logger $lg)`
  (also `?Logger`, `\App\Logger`, `&$lg`, `catch (E $e)`) didn't. Added a
  type-before-$var pattern. Reserved words can't be class names, so the
  looser lowercase-allowing capture yields no wrong edges.

Every pattern still relies on resolveMethodOnType validating the inferred type
actually declares the method (no edge on a mis-inference) — the same safety
net the already-covered languages use. Verified with a deterministic probe:
all four now disambiguate two same-named methods via the typed param (Java +
Kotlin as passing controls), full suite green (1930), no regressions.

Adds a parameterized regression test (Rust/Go/Dart/PHP), associating method to
type by qualifiedName so it holds where the method sits outside the type's
line range (Rust impl, Go decl).

385001398b fix(resolution): infer typed-parameter receivers in TS/JS (#1125) (#1129)
The local-variable receiver-type inference from #1108/#1110 covered typed
parameters for every language except TypeScript/JavaScript (+ TSX/JSX). The
TS/JS `:`-annotation pattern required a leading `const|let|var`, so it only
matched a local's own annotation (`const lg: Logger`) and never a bare
parameter (`function use(lg: Logger)` / `(lg: Logger) =>`). With a second
class sharing the method name — the case where a same-name fallback can't
paper over it — `lg.log()` resolved to no edge, dropping it from callers and
impact/blast-radius. TS/JS is the most common language pair in the userbase,
so this was a real precision gap.

Replace the keyword-anchored pattern with the keyword-free
`\b${r}\b\s*:\s*([A-Z][\w.$]*)`, mirroring Kotlin/Swift/Scala. It's a strict
superset (still matches `const lg: Logger`) plus the typed-parameter case,
and the capture stops at `<` so a generic-typed param
(`repo: Repository<User>`) still yields `Repository`. resolveMethodOnType
already validates the inferred type declares the method, so the looser match
produces no edge on a mis-inference — the same safety net the other
languages rely on; Swift already ships this identical bare-colon pattern with
the same theoretical ternary/dict-literal exposure.

Adds a regression test using two ambiguous classes + typed params, asserting
each call routes to its OWN class's method (verified to fail without the fix
and pass with it — a single-class version would pass either way via the
same-name fallback, which is why the collision is load-bearing).

358f400c40 feat(resolution): local-variable method calls in Lua, Luau, R, Pascal (#1112) (#1113)
Extends the local-variable receiver-type inference (#1108/#1110) to the
remaining supported languages with object-method calls. An empirical
sweep found Objective-C, Svelte, Vue, and Astro already resolved
`localVar.method()` (ObjC via message-send handling; the template langs
ride the TypeScript path), leaving Lua, Luau, R, and Pascal.

Lua/Luau/R were a resolution gap, not extraction: the call ref IS
extracted (`lg:log`, `lg$log`), but (1) the resolver's fast pre-filter
`hasAnyPossibleMatch` only understood `.`/`::` separators, so a `:`/`$`
ref was dropped before any strategy ran, and (2) matchMethodCall only
parsed `.`/`::` receivers with no local-var inference for these langs.
Fixes: pre-filter now checks the member/receiver around `:` and `$`;
matchMethodCall recognizes `lg:log` / `lg$log` and routes them through
the same inference + validated resolveMethodOnType path; and inference
patterns are added for Lua/Luau (`local x = T.new()` / `T()` / `x: T`),
R (`x <- T$new()`), and Pascal (`var x: T` / `x := T.Create`).

Pascal statement-form calls (`obj.Method;`) now resolve via the new
inference pattern. The assignment-RHS parameterless form
(`x := obj.Method`) is deliberately left as a field read by the existing
Pascal extractor — an intentional field-vs-call ambiguity tradeoff — so
it stays out of scope.

Validated with single-file and two-file same-name repros per language
(resolves to the right method; two-file is same-file-correct, #1079).
Adds all four to the local-variable inference test matrix. Full suite
green.

ed64db08b4 feat(resolution): infer local-variable receiver types across languages (#1108) (#1109)
Instance calls through a local variable — `const lg = new Logger();
lg.log();` — only resolved to the method in C++. Every other language
produced no `calls` edge, because the resolver had no way to learn the
receiver variable's type, so such calls were missing from callers,
impact/blast-radius, and explore flow traces.

Local variables aren't indexed as nodes (node-explosion), so — like the
existing C++ inferrer — this reads the enclosing function's source and
matches the receiver's declaration/initializer to recover its type, then
hands it to resolveMethodOnType. That validates the method actually
exists on the inferred type, so a mis-inference yields no edge, which is
what lets the per-language patterns stay simple. The scan is bounded to
the enclosing scope so a same-named variable in another function can't
leak in.

Generalizes the C++-only path in matchMethodCall into a language dispatch:
C++ keeps its dedicated header-aware inferrer; a new shared
inferLocalReceiverType covers TypeScript, JavaScript, Python, Java, C#,
Kotlin, Swift, Go, Rust, Dart, Scala, and PHP, matching each language's
declaration shapes (`= new T`, `= T(...)`, `= T.new`, `let x = T{}`,
`x := T{}`, `T x = ...`, `x: T`, etc.). For Java/Kotlin an import FQN
still pins which same-named class is meant (#314); other languages fall
back to the call-site's own file (#1079).

Ruby is not covered: its extractor emits no `receiver.method()` call
reference in the first place, so there is nothing for resolution to
resolve — a separate extraction-layer gap.

Adds a parameterized end-to-end test covering all twelve languages. Full
suite green.

63bc0fd037 fix(resolution): resolve same-named methods to the call site's own file (#1079) (#1107)
When two files each declared a same-named class with a same-named method
(e.g. `class Logger { void log(); }`), a call resolved to whichever
definition was indexed first — so a call in `b/svc` wrongly targeted
`a/svc`, mixing up that method's callers and blast radius.

The reported case was C++ instance calls, but the underlying pattern —
"multiple same-named candidates, pick the first-indexed, ignore the call
site's file" — lived in three resolution paths, each firing for a
different call shape and affecting different languages:

  - `obj.log()`     instance        -> resolveMethodOnType (C++)
  - `Logger.log()`  class receiver  -> matchMethodCall Strategy 1/2/3
                                       (Python, TypeScript, Java, C#)
  - `Logger::log()` qualified       -> matchByQualifiedName (C++, Rust)

All five sites now share one helper, `preferCallSiteFile`, that prefers
a candidate declared in the call site's own file when a name is
ambiguous. It runs after the `preferredFqn` block in resolveMethodOnType,
so Java/Kotlin import disambiguation (#314) — whose target is
intentionally in another file — is unaffected. The helper is a no-op
when there are fewer than two candidates or none share the call site's
file, so the common single-definition case is unchanged.

Adds 8 tests under `Same-name method disambiguation (#1079)`: the
`preferCallSiteFile` contract, resolveMethodOnType precedence (including
a guard that an import FQN still beats the same-file preference),
`matchByQualifiedName` disambiguation, and end-to-end index tests for the
C++ instance, TypeScript static, and C++ qualified call shapes.

ed39233f1a fix(index): yield during resolution so the liveness watchdog can't kill a valid large index (#1091) (#1105)
The #850 liveness watchdog SIGKILLs a process whose main-thread event loop
stalls past its window (60s default). It was extended to `index`/`init` in
#999, but reference resolution and callback-edge synthesis run synchronously
on that same thread — so on a large repo a legitimate, in-progress index gets
killed, and users had to disable the watchdog entirely (CODEGRAPH_NO_WATCHDOG=1).

Make the long synchronous spans yield cooperatively so the heartbeat keeps
firing during real work, while a genuinely wedged span (which never reaches a
yield) still trips the watchdog:

- synthesizeCallbackEdges yields between its whole-graph passes, and the heavy
  scanners (closure-collection, event-emitter, JSX-child, object-registry,
  field-channel) yield within their loops;
- batched resolution sub-chunks each batch with yields;
- the deferred chained-call and this-member post-passes yield per ref.

Behaviour-preserving — only timing changes; node/edge counts are identical.

Validated end-to-end with the real watchdog armed at the default 60s: the
released build is SIGKILLed partway through indexing the Swift compiler (27k
files, ~1.1M edges) and the TypeScript compiler, while the fixed build indexes
both to completion.

45d3293c6a fix(resolution): stop "Resolving refs" wedge on theme-vendoring repos; add exclude config + index watchdogs (#999) (#1009)
Three fixes for a repo that commits a large JS/TS theme/SDK (Metronic under
static/, ~1,600 tracked files):

1. A SECOND "Resolving refs" quadratic that #915 didn't cover. #915 capped
   import-name collisions; this caps method-name collisions (init/update/render
   re-declared on every widget), which flow through matchMethodCall Strategy 3
   and findBestMatch instead. New AMBIGUOUS_NAME_CEILING (default 500, env
   CODEGRAPH_AMBIGUOUS_NAME_CEILING): above it the fuzzy strategies decline
   rather than score K candidates — no proximity score can pick the one true
   target among thousands anyway. Resolving drops from O(K^2) to linear in refs
   (e.g. 900-file synthetic: 28.7s -> 3.4s), edge counts unchanged, and the cap
   never fires on normal repos (max real method-collision ~40).

2. A new `exclude` array in codegraph.json keeps git-TRACKED paths out of the
   index, which .gitignore can't do (enumeration is `git ls-files`). Mirrors the
   existing includeIgnored plumbing across the git, sync, and non-git-walk
   paths.

3. `index`/`init` now install the #850 liveness + #277 ppid watchdogs (which
   were serve-only), so a wedged or orphaned indexer self-terminates instead of
   pinning a core. The --liftoff-only relaunch's spawnSync can't forward
   signals, so killing the parent shim used to orphan the worker.

Tests: ubiquitous-name ceiling, exclude (incl. tracked-file exclusion on git +
non-git), orphan self-termination (POSIX), and ppid-parser units. Shared the
ppid parsers out of mcp/index.ts into mcp/ppid-watchdog.ts.

703629edc3 feat(c/c++): resolve function-pointer command tables — macro-built, conditional-compilation & bare arrays (#991) (#1003)
* feat(c/c++): resolve macro-built function-pointer command tables (#991)

C/C++ commands dispatched through macro-built function-pointer tables were
dead-ends in the graph: redis' `call` never showed up as a caller of any
command (`c->cmd->proc(c)`), because the table is generated into a #included
`.def`, the handler is buried inside `MAKE_CMD(...)`, the struct type is itself
a macro alias, the `proc` field uses a function-TYPE typedef, and the receiver
is a chained field access. #954 deferred exactly this shape.

Six composable additions to c-fnptr-synthesizer.ts close it:
- function-type typedefs (`typedef RET T(...)` + `T *f`) flag the field as a
  function pointer;
- multi-declarator fields (`struct redisCommand *cmd, *last`) each count as a
  slot/type (needed for positional alignment and the chain walk);
- chained/array receivers (`c->cmd->proc`) resolve through field types across
  all same-named struct layouts (redis has two unrelated `client` structs);
- `#include "x"` directives are followed (from raw source) so a non-indexed
  `.def` is read as a registration unit with the includer's effective macro env;
- function-like + object-like macros are expanded (params->args, type aliases)
  before positional/designated registration;
- a macro that expands to a brace-wrapped element (sqlite `FUNCTION(...)`) has
  one outer brace layer peeled.

Validated on two independent macro-table lineages at 100% target precision:
redis (209 commands via redisCommand.proc, `call`->every command) and sqlite
(69 FuncDef.xSFunc targets). No regression on the controls: git (cmd_struct.fn,
138 builtins), curl (Curl_cftype.*), lua (0). 0 non-function targets across all
five; +3 synthetic fixtures; full suite green.

* feat(c/c++): resolve conditional-compilation command tables (vim) (#991)

Vim's `:ex` and normal-mode command tables are the hardest fn-pointer-table
shape: the struct is defined INLINE with the array, the whole thing is behind
`#ifdef DO_DECLARE_EXCMD`/`DO_DECLARE_NVCMD` (switched on by the includer), built
by a macro the file conditionally redefines (`EXCMD`/`NVCMD` = the table element
under the switch, a bare enum id otherwise), and dispatched by a parenthesized
array subscript through a file-scope table: `(cmdnames[i].cmd_func)(&ea)`.

Four more composable additions on top of the macro-table work:
- a focused `#ifdef`/`#ifndef`/`#if defined`/`#else`/`#elif`/`#endif` evaluator
  drops inactive arms (unevaluable `#if EXPR` keeps its body); an indexed header
  is re-scanned in an includer's context only when that includer #defines a
  switch the header guards, with the include's macros re-read from the resolved
  text (the plain last-wins parse picks the wrong, enum, arm);
- inline `struct TAG {…} var[] = {…}` tables whose struct never became a node are
  parsed in place and registered;
- array-subscript receivers (`tbl[i].f`) strip the subscript and resolve the
  base through a global-var → struct-type map;
- an optional `)` before the call covers the parenthesized `(….f)(args)` form.

Validated on vim: 273 `:ex` commands (`do_one_cmd`→every command) + 67
normal-mode commands, 0 non-function targets, 0 cross-table misroute (registering
both tables is what stops `normal_cmd`'s `nv_cmds[i].cmd_func` from falling back
to the `cmdname` owner of the shared field name). Controls unchanged at 0
non-function (redis/sqlite/git/curl gain coverage from array/global dispatch, lua
still 0); +1 synthetic fixture; full suite green.

* feat(c/c++): resolve bare arrays of function pointers (#991)

The C/C++ fn-pointer synthesizer keyed everything on (struct type,
fn-pointer field), so a dispatch through a bare array of function
pointers — no struct, no field — was unbridged: an opcode/handler table
like `static op_t *opcodes[256] = {nop,…}` invoked `opcodes[op](…)` left
every handler with zero callers. Closes the last #991 deferred item.

Keyed by the array VARIABLE name (a new `arrayReg`, parallel to the
struct `reg`). Registration detects an array whose element type is a
function typedef — a function-TYPE typedef element (`opcode_t *ops[]`,
the `*` making it an array of pointers) or a function-pointer typedef
element (`zend_rc_dtor_func_t t[]`) — and reads its literal entries,
whether positional (`fn`/`&fn`), designated by index (`[IDX]=fn`), or
cast-wrapped (`(cast)fn`). Dispatch is `tbl[i](…)` / `(*tbl[i])(…)`,
gated on `tbl` being a known fn-pointer array (the precision anchor);
the fan-out reaches the whole set (a runtime subscript hits any entry),
like a command table. The same-file table wins on a name collision, so
two file-local `static opcodes[256]` (SameBoy's CPU + disassembler)
never cross. The fn-pointer typedef/field regexes now also tolerate a
calling-convention macro before the `*` (`(ZEND_FASTCALL *name)`), which
hardens the existing struct-field path too.

Validated on two independent lineages: SameBoy (GB emulator) — 147 edges
via `opcodes[]`, 0 cross-file leak; php-src (Zend) — 54 edges across 7
tables in the designated+cast+CC-typedef form. Control: lua 0 — its
`lua_CFunction searchers[]` is pushed into the VM, never C-dispatched, so
the call-gate fires nothing. No regression on the #991 corpus: redis
(835) / sqlite (683) struct edges byte-identical, git +3 / curl +20
legitimate new bare-array edges, vim 433 with all guards holding; 0
non-function targets across all. + 4 fixtures.

0a91d0f512 perf(resolution): fix O(K²) import-node blowup in "Resolving refs" (#915) (#965)
* perf(resolution): resolve imports to definitions, not sibling import nodes (#915)

"Resolving refs" crawled (tens of minutes) on large projects — most painfully
ones mixing a big front-end and back-end. An external package or module imported
across hundreds/thousands of files (react, a shared UI package, Python
logging/typing) is re-declared as an `import` node in every importing file, so
its unresolved import ref fell through to the exact-name matcher, which scored
all K same-named import nodes via findBestMatch — K refs x K candidates = O(K^2)
per package, producing only meaningless import->import edges.

Fix: exclude `import`-kind nodes as name-match targets (they're statements, not
definitions; real import->definition resolution is the import resolver's job).
Plus two safe constant-factor wins in findBestMatch: hoist the per-candidate
ref.filePath split, and skip cross-language candidates when a same-language one
exists (provably the same winner — same-language scores >=50, cross-language
maxes at 35).

Measured: superset (Py+TS) candidates scored 7.5M -> 833K (9x), non-import edges
preserved (+1618 now resolve to real defs), ~22K useless import->import edges
removed; kubernetes (Go) computePathProximity 37.2s -> 5.0s; synthetic 8k-file
mixed repo (K=4000) resolution 16.0s -> 1.7s. Full suite green.

* docs: correct stale better-sqlite3/wasm references to node:sqlite

The SQLite backend has been Node's built-in node:sqlite (real SQLite, WAL + FTS5,
from the bundled runtime) for a while — there is no native build step and no
node-sqlite3-wasm fallback. README and the docs site were already updated; this
catches the stragglers:

- CLAUDE.md: the src/db/ backend description and the sqlite-backend test note.
- src/db/index.ts, src/mcp/tools.ts: two code comments that still blamed "the
  wasm backend" for non-WAL behavior (reworded to "when WAL isn't in effect").

Leaves tree-sitter grammar wasm (web-tree-sitter / --liftoff-only) untouched —
that's a different, still-current use of wasm.

* chore(telemetry): drop the dead sqlite_backend field (schema v2)

node:sqlite is now the only backend, so the `index` event's `sqlite_backend`
field was a constant ("native") carrying no signal — and the `install` event
never actually sent it. Remove the field and the backendKind() helper, bump the
telemetry SCHEMA_VERSION 1 -> 2, and update TELEMETRY.md + docs/design/telemetry.md.

The ingest worker is deliberately left tolerant: `index` doesn't require the
field and schema_version validates as nonNegInt(99), so v2 events ingest fine and
old clients still sending v1 + sqlite_backend keep validating too. Added a legacy
comment there explaining it's safe to drop once old-client share is negligible.

telemetry.test.ts: the assertion pinning schema_version and a stale-claim fixture
line updated 1 -> 2. All telemetry tests pass.

a89315645d feat(go): index GoFrame g.Meta routes and bind them to controller methods (#747) (#957)
GoFrame's standard router binds routes reflectively (group.Bind(ctrl)): the path
and method live in a g.Meta struct tag on a request type, and the controller
method that serves it is matched by that request type at runtime — so there was
no path string and no edge from a route to its handler, and "where is this route
handled / where are routes bound to controllers?" could only be answered
lexically (issue #720's report).

- frameworks/goframe.ts: detect gogf/gf in go.mod, extract each path-bearing
  g.Meta into a route node (requires path:, so response mime:-only tags are
  skipped), encoding the package-qualified request type for the join.
- goframe-synthesizer.ts: join each route -> the controller method whose
  signature takes that request type — NOT by name (DeptSearchReq is served by
  List) — keyed pkg.Type to disambiguate the many identical bare names a large
  app defines one-per-module, with an addon-root tiebreak for cloned demo addons.
  Edge kind calls, provenance heuristic, synthesizedBy goframe-route, surfaced as
  a dynamic-dispatch hop in codegraph_explore.

Validated on real repos: gf-demo-user 7/7, gfast 65/68 (3 genuinely
handler-less), hotgo 242/247 (98%) — 100% precision (0 non-controller handlers,
0 core/addon cross-binding), node count stable. Agent A/B (gfast, sonnet/high,
2 runs/arm): with codegraph 1 explore call / 0 Read / ~20s vs without 7.5 Read
avg + grep-hunting for the non-existent literal route string / ~42s; same correct
answer.
