Colby McHenryandClaude Opus 5 dc4fd755ef merge: recognize Wrangler-style generated banners (CG-25)
A generated Cloudflare Wrangler ambient-types file was not flagged generated, so
it ranked with no penalty and competed with hand-written source on generic token
overlap. The banner shape it uses — "Generated by <tool> by running <command>" —
matched none of the existing content patterns, all of which require DO NOT EDIT,
a standalone @generated, or the "auto(matically) generated by" phrasings.

Precision is held by requiring TWO 'by' clauses: the banner must name a tool and
then say 'by running'. Ordinary prose ("the report is generated by running the
nightly job") has only one and does not match.

Colby McHenryandClaude Opus 5 57e0854213 fix(explore): recognize Wrangler-style "generated by … by running" banners (CG-25)
Cloudflare Wrangler's `worker-configuration.d.ts` (~12k lines of ambient
types) carried no banner any GENERATED_CONTENT_PATTERNS entry matched:
every existing marker requires `DO NOT EDIT`, a standalone `@generated`,
`<auto-generated>`, or the literal `automatically/auto-generated by`
phrasings. Wrangler emits a bare `Generated by Wrangler by running
`wrangler types``, so the file ranked with pen 1.00 and won 79.4% of an
explore envelope on generic token overlap alone (CG-24).

The discriminator is the reproduction instruction, not the word
"generated": the banner must name a tool AND then say `by running`, i.e.
two separate "by" clauses. That keeps prose out — "the nightly summary is
generated by running the ETL job" has only one — while catching every
CLI-driven emitter that tells you how to regenerate.

Precision swept over 441,856 files across the whole local source tree: 5
hits, all genuine Wrangler output, no false positives.

Isolated before/after on the CG-24 repro (same query, same index, only
the `files.generated` flag differing):

  before  pen 1.00  score 115.0  share 79.4%  3 files rendered
  after   pen 0.30  score  35.4  share 21.1%  4 files rendered

The new pattern stays in the existing table position, below the header
window the detector scans, so the module still does not classify itself.

Colby McHenryandClaude Opus 5 7cbde95ce2 fix(explore): pay every admitted file on every render path (CG-26)
The invariant this closes: every admitted file receives at least its
reservation before any file draws on carry-forward slack. CG-30 bounded an
oversize cluster member and CG-31 gave the cluster path a displacement guard;
three holes were left, and each one starved a file that had been admitted,
reserved and — in the worst case — rendered.

1. The whole-file arms had no displacement guard. BUY's fit test read
   `renderCeiling - totalChars` (everyone's room) while its source-space
   sibling refused the same trade, and GRACE was not fit-tested at all.
   okhttp's CallServerInterceptor.kt shipped 8,499 chars on a 5,964 funded
   ceiling and the rank-6 file below it delivered nothing. Both arms now test
   the render they actually produce against `fundedHeadroom`, and a whole
   render that does not fit falls through to clustering instead of skipping
   the file.

2. Every section was charged a flat 200 chars while a real header runs
   300-500. The loop believed it had room it did not have — okhttp allocated
   26,601 against a 24,400 ceiling — so the final truncation threw a
   fully-rendered section away. Sections are charged their real cost now, the
   owed-below arithmetic uses a per-file overhead estimated from the file's own
   symbols, and a marginal overrun trims the weakest cluster (or windows the
   last one into the room that is left) rather than skipping the file over a
   rounding difference.

3. `owedPayableBelow` held all-or-nothing. When the last admitted file's FULL
   reservation no longer fit, nothing was held for it: on the precise-query
   fixture the rank-5 file took 4,134 chars against a 2,948 reservation while
   rank 6 — admitted, reserved 2,539 — was left 4 chars and skipped. It now
   holds the remainder while that remainder is still worth a section
   (MIN_CHARS).

And the epilogue is budgeted instead of discarded. The flat 600-char margin was
neither the epilogue's size (1,064 gin, 1,788 django, 2,231 excalidraw) nor a
bound on it, so four of six suite repos shipped with no pointer list and no
reminders at all. The loop now reserves the epilogue's FLOOR — the one line
that says an uncovered area exists, plus a pointer for every file whose bytes
were deliberately withheld (CG-12) — and the rest is fitted to the room that
actually remains, in priority order, entry by entry. Sized from the real
strings; no constant was swept against the suite.

Deterministic, same clean-rebuilt indexes, baseline = CG-31 tip:

  repo         base source   new source   files      ceiling
  django            20,791       20,878   6 -> 6     was discarding its epilogue
  tokio             21,521       21,607   5 -> 5     was discarding its epilogue
  okhttp            19,034       18,870   5 -> 6     +1 file delivered
  excalidraw        20,204       19,652   8 -> 8     keeps its pointer list
  gin               10,776       10,776   4 -> 4     byte-identical
  alamofire         11,662       11,662   2 -> 2     byte-identical

No repo truncates any more and none loses a file. okhttp and excalidraw trade
164 and 552 source chars on their LAST-ranked file for the pointer list naming
what the response could not cover — bytes the CG-31 tip only had because it
over-filled a ceiling it mis-measured and then discarded the epilogue whole.

Colby McHenryandClaude Opus 5 c54e0080c2 fix(explore): keep the drift warning out of the cuttable epilogue (CG-31)
The '⚠ changed on disk after the last index sync' banner is an honesty claim
about source we DID render — line refs elsewhere in the response may be
shifted — not a note about the response. Drawing the epilogue boundary after
it means the size cut can never be what silences it. Suite numbers unchanged.

Colby McHenryandClaude Opus 5 f1fecb8232 fix(explore): fund the guard from room that exists, and cut the epilogue first (CG-31)
Two corrections found by measuring the first cut of the guard against the
6-repo suite. The first version held back the FULL sum of the reservations
below a file. On django that took 2,319 chars off a file the agent receives
and handed them to a section the hard ceiling then threw away — the guard's
own failure mode, one layer down. tokio lost 1,298 the same way.

1. `owedPayableBelow` — hold back only the prefix of what is owed below that
   the response can still PAY, in rank order. A promise the ceiling cannot
   reach is not a claim on this file's bytes.

2. The final truncation now spends the EPILOGUE before it spends a rendered
   file section. It used to cut at the last section header, dropping that
   section AND the trailing notes; dropping the notes alone is almost always
   enough. A section is source the agent otherwise has to Read; the epilogue
   is a pointer list and two reminders, and the note that replaces it carries
   the "explore these names" instruction forward.

Also count `flow.text` in `totalChars`. It is prepended to `lines` to make the
final output, so the render loop always spent against a ceiling it was ~2K
under on symbol-bag queries.

Deterministic, same clean-rebuilt indexes, both builds (baseline = CG-30 tip):

  repo         base source   new source      files
  django            20,033       20,791   5 trunc -> 6
  excalidraw        18,776       20,204   7 trunc -> 8
  okhttp            15,628       19,034   4 trunc -> 5
  tokio             20,340       21,521   4 trunc -> 5
  gin               10,776       10,776   4 -> 4   (byte-identical)
  alamofire         11,662       11,662   2 -> 2   (byte-identical)

No repo delivers less; four stop truncating. `funded` in the diagnostic now
reports the render CEILING the guard allows, which is what every render path
is actually bounded by.

Colby McHenryandClaude Opus 5 089dcc276f fix(explore): hold back what is still owed below a clustered render (CG-31)
Carry-forward slack let a file spend what the files ABOVE it left on the
table. Nothing held back what was promised BELOW it. The whole-file BUY arm
has always refused that trade (`owedBelow`); the cluster path read `headroom`
— what is left before the hard ceiling — instead of what is still owed, so
`fileBudget` and `SPINE_CEILING` could pay a 1.5x overshoot out of another
file's reservation.

`fundedHeadroom` is the same inequality in the units the cluster path spends
in: source PLUS the per-section overhead each unreached file will charge.
Floored at the file's own reservation — a kept promise is not a displacement —
and it is <= `headroom` by construction, so it is the only bound the three
render sites need. The skeleton path's `bodyCap` takes it too.

Measured on `__tests__/fixtures/displacement-ts` (a 4-stage pipeline padded
past 500 files, where the 24K envelope genuinely saturates the 24.4K render
ceiling):

  before  ingest.ts emitted 9,301 on a 6,289 spendable, then lost the whole
          section to the final ceiling — 0 delivered. types.ts and sink.ts
          skipped `budget-whole-file`. 3 of 6 admitted files delivered.
  after   ingest.ts bounded to the 4,913 actually free. 6 of 6 delivered,
          envelope 14,908 -> 22,066.

The self-query allocation fixture flips back to PASS with it, on a clean full
rebuild of this repo's index (CG-33). Its `afterCG30` verdict blamed an
over-RESERVED incidental file; the reservation was identical in both arms —
the file was over-SPENDING. Recorded honestly in `afterCG31`.

Colby McHenryandClaude Opus 5 cd1ea27ea8 fix(explore): restore the CG-30 bound d652c14 reverted
d652c14 was committed while an ab-new-vs-baseline run had the engine checked out
at the BASELINE ref — that harness swaps src/ files mid-run and restores them on
exit — so it captured main's tools.ts and explore-diagnostics.ts and silently
undid 765c06a. Restored from 765c06a, with d652c14's doc tweak re-applied.

The A/B runs started after that commit are void with it (their "changed:" line
lists only explore-diagnostics.ts, i.e. both arms ran the same retrieval code)
and are re-run rather than reported.

Colby McHenryandClaude Opus 5 d652c148f6 docs(cg-30): changelog entry + record the self-query probe flip honestly
The self-query allocation probe fixture's delivered-share gates now fail. The
cause is not the new bound: allocation is unchanged between arms (parse-run.mjs
32.3% vs 33.9% on main) and tools.ts delivers the same 8,282 chars in both. What
changed is that the incidental file now DELIVERS — on main its whole section was
cut by the hard-ceiling truncation, so the fixture passed on truncation luck.
Every file on this repo obeys the new bound (max 1.40x of spendable).

Recorded as `afterCG30` with that reasoning rather than tuning the bound to
restore the pass. The over-reservation it exposes is epic CG-24's subject.

Colby McHenryandClaude Opus 5 765c06aa40 fix(explore): bound how far an oversize cluster member may overshoot (CG-30)
shrinkCluster keeps an oversize cluster's highest-importance member WHOLE on
purpose — an empty file section sends the agent to Read, the outcome explore
exists to prevent. What it lacked was a bound, and "never empty" quietly meant
"never bounded": on the reporting repo one file emitted 22,376 chars against a
9,181-char reservation (2.44x), past both the per-file budget and the spine
ceiling. That overshoot is what collapses `headroom` for every file below it.

The same rule has a second face. When the top member is bigger than the whole
response ceiling, the file does not overshoot — it is dropped entirely at the
renderCeiling check, so the agent gets nothing for a file it named.

renderCluster now takes a ceiling (1.5x what the file may spend — the same
multiple SPINE_CEILING already draws, and never below the cap, so a cluster
that fits is untouched). Past it the member is WINDOWED on whole lines rather
than emitted whole or dropped: leading window plus, on a flow cluster, a window
on the spine's call site. A partial window shorter than 12 lines is dropped
instead — a sliver in the session record forces the next call's dedup to shred
the block around it or re-send it — unless nothing else was emitted, where the
never-empty floor wins.

Measured on the new fixture, pre-fix vs post-fix:
  monthly.ts    12,391 chars on a 3,334 budget (3.7x)  →  4,941 (1.48x)
  quarterly.ts  dropped, no headroom left               →  4,004 delivered

Also: the diagnostic now reports `spendable` (reservation + inherited slack)
alongside `reserved`. Every render bound reads the former, so reporting only
the latter makes an ordinary carry-forward read as a file spending over budget
— and it made the overshoot this issue is about unmeasurable. A windowed file
is now flagged `clipped` too, instead of presenting a window as the whole file.

Colby McHenry ab38d1f090 feat(explore): point at source this session already sent, don't send it twice (CG-18)
A later explore call re-served whatever it re-ranked, so on the #1500 report
the 4th call spent its envelope on the spine the 1st call had already
delivered. CG-17 recorded what was served; this acts on it.

What a withheld span becomes is the whole design: a POINTER, never a silence.
An insufficient-feeling response is what sends an agent to Read, and one or
two of those early in a session teach it to abandon codegraph — so the
replacement names the file, the symbols and the line spans, and says both
that the source came from THIS conversation and that the file has not changed
since.

- Content fingerprint, not the drift flag, gates it. They answer different
  questions: two calls inside one drift window served the same current bytes,
  while a file edited AND re-synced between calls is never "stale" and yet
  the agent's copy is now wrong. An edited file re-emits in full.
- Only a covered run of >= 8 lines is replaced, and a remainder under 160
  chars folds into the pointer. Below those the pointer costs more than the
  source and the block reads as shredded — a fence holding `228\t` is a
  broken-looking response, which is the expensive failure.
- The reclaimed bytes go to files the agent has NOT seen, two ways: a smaller
  `sourceSpent` hands slack down CG-21's carry-forward pool, and a fully
  back-referenced file gives up its maxFiles slot the way a cliffed one does.
  Within a file, the cluster shrink now reads the DEDUPED length, so it never
  drops new symbols to make room for source it isn't sending.
- If dedup suppresses everything and nothing new takes its place, the top
  suppressed file is spliced back in whole. An all-pointer response is the
  shape that reads as "codegraph found nothing"; one re-served file is the
  cheaper mistake.

Kill switch: CODEGRAPH_EXPLORE_DEDUP=0.

Colby McHenry fc31b1e2bf feat(mcp): remember what explore already served this session (CG-17)
Explore answers every call as if it were the first: no record of the files
and line ranges it already sent, so a 4th call re-serves the 1st call's
spine and the tier call budget can only be asked for, never enforced.

Track it per MCP session, per resolved project root — files, coalesced line
ranges, bytes, and the call's index in the session. Nothing reads it yet:
the response is byte-identical, which the suite pins against an untracked
call of the same query.

The daemon shares ONE ToolHandler and a pool of worker threads across every
connected client, so the state can live neither on the handler nor in a
worker. It lives on MCPSession and is handed to execute() per call; the
session's view rides DOWN on the args and the call's emission rides BACK on
the ToolResult, both as plain properties so they survive the structured
clone to and from a worker. execute() records the emission on the main
thread and deletes it unconditionally — including for callers that track
nothing, like the CLI — so it can never reach the wire. A view a client
spells itself is discarded rather than trusted.

Ranges are reported by the render loop itself (buildSection now returns the
spans it slices alongside the text), and only files that survive the final
hard-ceiling truncation are recorded. Where a bound forces a choice the
record keeps FEWER ranges than were emitted: under-reporting re-serves
something the agent has, over-reporting withholds source it never saw and
costs a Read.

Every bound caps detail only — callCount keeps counting past eviction, so
CG-19's decay can't reset itself every 8 calls.

Colby McHenry fca7d87047 fix(explore): a funded whole-file buy must also fit the render ceiling (CG-21)
Found reviewing the CG-21 fix rather than by a failing test, and it is the
same defect inverted. A whole render that overruns `renderCeiling` is
skipped ENTIRELY (the branch refuses to slice a file mid-method), so a buy
that is approved by the funding pool but refused by the ceiling trades a
clustered section for NO section.

Only reachable on the 24K tiers. The funding line is
`reservedTotal + 0.15 * envelope` — ~27.2K when a medium repo saturates —
while `renderCeiling` is `min(1.5 * envelope, 25000) - 600` = 24.4K, so
funding can approve ~2.8K the ceiling then refuses. At 13K the line is
~14.4K against an 18.9K ceiling and the two cannot cross, which is why the
small-tier fixtures cannot see it.

Failing the test in `buysWhole` drops through to the cluster path, which is
bounded by `headroom` and always renders something. The GRACE arm is left
alone deliberately: a file within a sliver of its reservation that still
does not fit is genuinely at the end of a full response, and that predates
this epic.

Verified inert on the three A/B repos, so the agent A/B measured the same
behaviour: excalidraw byte-identical on 3 queries, client-go byte-identical
on 3 queries, express reproducer unchanged at 15,984. Full suite green
(2,867 passed; one unrelated fs.watch timing flake that passes 30/30 in
isolation).

Colby McHenry fa7fb8d127 fix(explore): spend the reservation instead of dropping it (CG-21, #1500)
A file whose proportional reservation lands below its own size stopped
rendering whole, and the fallback cluster render could leave most of that
reservation unspent — the bytes were neither delivered nor redistributed.

Found by CG-15's agent A/B on the express control: `lib/utils.js`, the
top-ranked file, was reserved 3,870 chars and spent 583. The whole-file
grace bound (reservation + a sliver) sat just under the file's 5,293
bytes, so the whole render was declined and three matched symbols became a
stub. The source envelope fell 13,849 -> 9,241 against an UNCHANGED
budget, and the agent Read the file back four times in 1 run of 3.

Two levers, per the task's candidate fixes:

- WHOLE_FILE_BUY_FRACTION: a reservation that already covers 60% of a
  file buys the whole file. Funded from ONE shared overshoot pool sized
  at 15% of the envelope, spent in rank order. Per-file funding is the
  version that fails, and it fails the same way the bug does — the merit
  test is a ratio, so several files qualify at once and N independent
  overshoots push the last section past the render ceiling. Measured on
  the payroll fixture: three files bought whole and `payslip_builder.go`
  was dropped entirely. A dropped section is strictly worse than a
  clustered one.

- Reservation carry-forward: what a file cannot spend goes to the next
  file down, bounded by MAX_SHARE. Tracked as two running totals rather
  than a `spent` variable threaded through the render loop's dozen exit
  paths, so no path can forget to account, and symmetric — a buy that
  overshoots suppresses slack until a later under-spend covers it.

Express reproducer: `lib/utils.js` 583 -> 6,268 whole, envelope 9,241 ->
14,505 on the same 13,000 budget. The `memory-budget.ts` exception CG-14
documented is RESOLVED rather than re-justified: it ships whole again at
5,672 (27.3%) while `src/mcp/tools.ts` rises to 52.6% — so the answer
file wins the envelope AND no previously-unclipped file is clipped, which
is CG-12's own acceptance criterion finally holding.

Two hermetic fixtures added, one per lever, because nothing in the suite
had this shape — which is how it shipped. Both mutation-tested: removing
the buy arm reddens 3, removing the carry-forward reddens 2, and removing
the funding guard reddens 4 (including payroll's dropped
`payslip_builder.go`). Their `fixture shape` blocks are load-bearing: the
gates pass vacuously if a target ever drifts inside the grace bound, so
the window is asserted directly.

Full suite green (2,868 passed); both #1500 regression fixtures pass.

Colby McHenryandClaude Opus 5 1d9206d2d0 test(explore): lock down proportional byte allocation (CG-14, #1500)
Coverage for the CG-12 allocator, built around "would this go red if the
lever were removed" rather than line coverage — every way this regresses
is silent, ending in an agent falling back to Read.

Unit (`explore-proportional-allocation.test.ts`, 18 -> 38): calibration
pins, envelope safety across every tier and 30 candidate shapes, the
cliff boundary, spine weighting/trim survival, the diffuse control, and
the degenerate inputs — identical scores, a lone file, a runaway top
scorer, zero results, maxFiles 0, a non-finite score.

End-to-end (`explore-allocation-e2e.test.ts`, new): CG-6's second
regression fixture as a deterministic synthetic mirror — a large relevant
file, a small helper that used to win by shipping whole, and an
incidental `explore`/`BUDGET` collision — asserting per-file budget
share, not file presence. Plus degenerate result sets and a survey-style
diffuse control through the real render loop. The live self-query arm
stays in probe-allocation.mjs, where drift is a number to re-baseline
rather than a red suite.

Reverting the render loop to the pre-CG-12 rules reproduces #1500 on the
mirror exactly and takes 5 e2e + 2 payroll gates red:

  file                     score  pre-CG-12       CG-12
  src/mcp/allocator.ts      77.5  4,843 (39.7%)   9,335 (80.1%)
  src/util/budget-math.ts   36.0  6,079 (49.8%)   1,037 ( 8.9%)

Two defects the invariants surfaced, both fixed in tools.ts:
- rounded shares could sum past `pool`, so "reservations fit the
  envelope" was approximate rather than exact; both terms now floor
- a non-finite score made every share Infinity/Infinity, handing the
  render loop a NaN allowance; `weightOf` now fails safe to 0

Also adds a hard-ceiling gate to the payroll fixture — at 19.3K against
a 19.5K ceiling it is the only fixture that stresses the ~25K inline cap
— and exports EXPLORE_ALLOCATION so invariant tests read the constants
while one test pins the literals.

Colby McHenryandClaude Opus 5 5f7f5f59df feat(mcp): score-proportional byte allocation for explore, with a relative cliff (CG-12, #1500)
The explore envelope used to follow FILE SIZE, not relevance. Every admitted
file was capped at the same flat `maxCharsPerFile`, while the whole-file rule
handed anything under `maxCharsPerFile * 3` its entire contents — a 3x swing
decided by how big a file happened to be:

  - self-query: `memory-budget.ts` (score 18) shipped whole and took 51.2% of
    the response; `src/mcp/tools.ts` (score 41, 4x the graph mass, 3x the term
    hits — it holds the allocator itself) was clipped at 3,800 and got 32.9%.
  - #1500 Go fixture: two generated CRUD files shipped whole at ~4.5K each AND
    consumed two of the tier's four file slots, so `BuildPayslip` — the
    hand-written "calculate" half of the question — ranked #6 and never
    rendered at all.

`allocateExploreBudget` now reserves each ranked file a share of the envelope
before anything renders, so the render loop spends a reservation instead of
racing for whatever the files above it left:

  - weight = score x worth x (spine ? 2 : 1), where `worth` is `rankPenalty`
    applied a SECOND time — ranking answers "is this file about the query",
    allocation answers "will these bytes teach the agent anything", and
    generated CRUD can legitimately rank while its bytes stay boilerplate;
  - a relative cliff at 15% of the top weight (capped at SCORE_FLOOR_MAX, so a
    god-file can't silence peers the score floor just admitted) gives a file
    ZERO source — path, symbols and line numbers only — and crucially frees its
    `maxFiles` slot for a file that earns its bytes;
  - every admitted file gets MIN_CHARS, then the remainder splits by weight:
    the floor keeps a diffuse survey question returning a spread, the remainder
    concentrates a precise one;
  - the flat per-file cap is retired as the primary guard, leaving a 70%-of-
    envelope safety valve.

Two changes were needed to make the reservation bite: an oversize cluster now
shrinks by whole MEMBER symbol ranges (a single-cluster god-file previously
took ~40% more than allotted, and the file below it was dropped for lack of
room), and the arrival-order budget stops are gone — they cut files by the
order they were reached rather than by merit.

Measured: payroll-go answer group 25.6% -> 78.7%, generated 57.4% -> 0%, and
`func (s *Service) BuildPayslip` now delivered; self-query `tools.ts` 18.5% ->
60.6%, past the epic's >50% bar. Controls hold: cobra/gin diffuse survey
queries keep their file spread (3->3, 3->4), express's middleware query is
byte-identical, and gin's flow query moves its top file from the thin `ginS`
singleton wrapper to `routergroup.go`.

One documented exception to "no previously-unclipped file becomes clipped":
`memory-budget.ts` was unclipped-whole at 5,672 and now clusters within its
3.1K reservation. That is the epic's own diagnosis of the bug — it scored 18
against 58 and was taking the larger slice purely for being small.

Colby McHenryandClaude Opus 5 a3898cdc70 feat(mcp): relevance scoring overhaul for explore — kill incidental name-collision matches (CG-10, #1500)
Explore's per-file relevance awarded +50/+10/+3/+1 by match class and admitted
anything scoring >= 3. Neither half held up: the tier said HOW a symbol reached
us, never whether the match was evidence, and an absolute floor admits noise on
any repo where the top file scores 50+. Three scripts/agent-eval/*.mjs harnesses
took 63% of this repo's own "how does explore allocate its output budget" answer
on nothing but an unused `const explore` and a `const BUDGET`.

Four levers:

- KIND WEIGHT (RELEVANCE_KIND_WEIGHT): callables and types 1.0, members ~0.5,
  variable/constant/parameter 0.15-0.35. A weak-kind symbol with no usage edge
  anywhere in the graph (`contains` excluded — nesting is not usage) drops to
  0.08. Only weak kinds in the top two tiers pay for the DB probe; the subgraph's
  own edges answer most cases free. No measurable latency change (210 vs 211
  ms/call, n=12 interleaved).

- PERIPHERAL CAP: nodes >=2 hops from any match accumulate into a bucket capped
  at 5. Uncapped they added a flat +1 each, so a file grew more relevant by being
  bigger — parse-session.mjs reached 22 off one constant plus twelve unrelated
  symbols.

- RANK PENALTY: generated files x0.3, low-value x0.5, applied to the score AND
  the graph mass. Score alone would not have fixed #1500 — the generated CRUD
  carries MORE graph mass than the hand-written use-case, and graph mass outranks
  score in the comparator. Self-normalizing, never a hard exclusion.

- RELATIVE FLOOR: clamp(topScore * 0.2, 1, 10). Capped at one full-strength
  direct match so concentration elsewhere can never exclude one (without it a
  named-seed-heavy file pushed the floor to 21 and dropped a file the agent had
  named by class name). Backfills to 3 candidates when it would leave fewer, and
  drops the evidence requirement rather than return nothing at all.

excludeLowValueFiles was dead config — declared per tier, read nowhere; the
test/spec exclusion has been unconditional for a while. Removed. The real gap was
the detector: `isLowValue` anchored on a leading `/`, so a repo-ROOT `test/` dir
(express, cobra, most of npm and Go) never matched — express's routing question
spent 59% of its envelope on three test files. Anchored at `^` too, and the
filter now runs before the floor and judges "are there other candidates?" on the
whole gather.

Measured before/after on the same indexes (baseline bd86ad2):
- payroll-go fixture: generated 57.4% -> 23.5%; answer 25.6% -> 61.5%; cycle.go
  delivered 0 -> 38.9%. Generated ranks #3/#4, was #1/#2.
- self-query fixture: eval scripts 72% -> 0%; tools.ts ranks #1.
- express "route a request": 59% to test/* -> lib/application.js + lib/response.js
- cobra x3, codegraph "indexing pipeline": byte-identical (control)

Diagnostic gains a per-file penalty multiplier and NodeKind mix, so "why did this
file score X" is legible. Selection stages reordered to match the pipeline.

CG-6's gates flip from it.fails to live regressions except the byte-split ones,
which stay open for CG-12 (allocation still follows file size within the ranked
set).

Colby McHenryandClaude Opus 5 16e17495f4 feat(extraction): content-based generated-file detection (CG-5, #1500)
`isGeneratedFile` was path-only, but Go's own convention is a CONTENT
marker (`// Code generated by <tool>. DO NOT EDIT.`), not a filename one.
A Go monorepo with generated CRUD in ordinarily-named files sitting beside
hand-written use-cases was therefore invisible to every generated-file
down-rank in the codebase — that is #1500.

Measured on kubernetes/client-go (2,453 Go files): the canonical banner
appears in 2,001 of them, the path check flags 0, the new content check
flags exactly those 2,001 — no false positives, no misses.

Design: decide at INDEX time (content is already in memory for parsing),
persist on `files.generated`, read from the DB. Explore never reads file
headers per request.

- `hasGeneratedHeader(content)` recognizes the standard banners — Go's,
  protoc's, `@generated`, `<auto-generated>`, Thrift, OpenAPI Generator,
  FlatBuffers, bindgen, ANTLR. Precision-first and fenced three ways: an
  8KB/60-line header window, a comment-line requirement (leader or open
  block comment), and markers tight enough that prose can't trip them. A
  generator's own source, holding the banner as a string constant in its
  body, is not flagged; neither is this module itself (pinned by test).
- `isGeneratedFile(path)` is unchanged — cheap, sync, still the fallback.
- Schema v9 adds `files.generated` + a PARTIAL index. DDL only, no
  backfill: the flag derives from content the migration cannot see, so
  rows stay 0 until a re-index and every reader unions the flag with the
  path check — an un-migrated index keeps pre-#1500 behavior rather than
  regressing. Re-index required; noted in the CHANGELOG.
- `generatedPredicateFor(paths)` gives ranking a bounded probe + O(1)
  lookups. Bounded, not cached: no invalidation, so a ranking call can
  never serve a verdict the last sync already replaced. Wired into explore
  ranking, findSymbolMatches, findAllSymbols, search (MCP + CLI), the
  context formatter, and the dominant-file/route-file hygiene filters.

Cost (acceptance bar was no measurable index-time regression): a single
unanchored `/generat/i` test over the header rejects ~every hand-written
file before any line splitting. 4.6 µs/file on client-go (worst case —
82% generated). End-to-end `codegraph init` on client-go, n=3 alternating
arms: 5.73s median with detection vs 5.76s path-only baseline; the arms
cross over between runs, so the difference is inside run-to-run noise.

Scope note: generated status remains a stable TIEBREAK at equal score,
exactly where it was. Making it a strong negative signal is CG-10, which
this unblocks by making the signal correct and available.

Two pre-existing tests hard-coded schema version 8; both now track
CURRENT_SCHEMA_VERSION (or the migration table) so future migrations
don't require editing them.

Colby McHenryandClaude Opus 5 b37f191f5a feat(mcp): per-file allocation diagnostic for explore (CG-4)
How codegraph_explore divides its byte envelope among files was
unobservable — you could read a response and guess, but not say "this
file took 16% and that one took 20%." Nothing else in the budget-
allocation epic is measurable without that.

CODEGRAPH_EXPLORE_DEBUG now emits one report per explore call (stderr
table, stderr JSON, or a JSONL sidecar path). Per file: relevance score,
graph mass, term hits, ranking flags, render mode, bytes allocated vs
delivered, both shares, and whether it was clipped — plus why a ranked
candidate never rendered. Totals cover envelope vs maxOutputChars vs the
hard ceiling, the source/meta split, the selection funnel, and the score
floor and relevance-gate thresholds applied.

Allocated and delivered are reported separately on purpose: they diverge
exactly when the 25K ceiling truncates, and conflating them is how a
dropped trailing file goes unnoticed.

Off by default and byte-identical when off — it ships in the product
binary, and a diagnostic that perturbs the response by one byte would
invalidate every A/B taken with it on. ExploreDiagnostics.start() returns
null unless the env var is set, so every call site is a `diag?.` no-op.

Baseline recorded in docs/design/explore-budget-allocation.md: on this
repo, src/mcp/tools.ts gets 15.8% of the envelope while three weakly-
relevant agent-eval scripts take 61% between them — despite tools.ts
carrying 5.4x the score and 2.6x the graph mass of any of them. Small
files ship whole; the large answer file is clipped at maxCharsPerFile.
Rank ordering is correct and buys nothing. The loop also allocated 23,193
chars against an 18,000 budget.

f6ac7b36e6 fix(mcp): blast radius follows caller chains before claiming no test coverage (#1475) (#1494)
The "no covering tests found" flag only inspected a symbol's direct
callers, so helpers exercised transitively by tests (logDebug runs
1,471x under npm test) were reported untested — wrong for ~40% of
flagged symbols per the issue's measurement.

The check now BFSes up the caller graph (3 hops, 64-lookup budget per
entry) and reports indirect coverage as "tested via callers: <files>".
When nothing is found it claims only what was measured — "no tests
found within 3 caller hops", or the weaker "no test calls this
directly" if the budget ran out — and drops the warning glyph.

38580e0b04 fix(python): bare class references produce references edges to classes (#1478) (#1493)
Python's class-as-value idioms (return SomeClass, x = SomeClass, registry
dicts, classes passed as arguments) produced no references edges, so
callers/impact on a Django/DRF serializer missed the views that consume it.
Three gates dropped them:

- return_statement was never dispatched by PYTHON_SPEC (kernel mirrored)
- the extraction gate (definedHere) collected function/method names only
- resolution accepted function/method targets only (matchFunctionRef +
  the function_ref import fast path)

Capture return_statement for Python (single expression; tuple returns not
descended), admit same-file CLASS names to the gate, and accept class
targets for Python bare identifiers — scoped to Python so the TS/JS KIND
FILTER contract is untouched. The docopt false-positive mechanism behind
the function-only rule (lowercase locals vs same-named methods) doesn't
transfer: methods stay excluded for bare ids, and the same-file/import
gate + unique-or-drop rules still apply.

Probed on django-rest-framework (~250 files): 559 new references→class
edges, 10/10 sampled genuine (serializer_class = AuthTokenSerializer, the
ModelSerializer field-mapping registry, aliases, ctor args, isinstance).
EXTRACTION_VERSION 24 → 25.

f2a5df34de fix(mcp): never serve a mis-sliced symbol body from a file that drifted from its index (#1474) (#1492)
codegraph_node / codegraph_explore read CURRENT bytes but slice them at
INDEXED line ranges; after an un-synced edit that slice can be a DIFFERENT
symbol's code served under the requested name — isError: false, introduced
by the 'verbatim … do not Read' guarantee. The watcher-based pending (#403)
and degraded (#876) banners cannot cover a project reached via projectPath:
cross-project instances have no watcher, by construction.

Freshness is now verified at the point of emission from data the index
already stores: one stat per rendered file (size + floored mtime, the sync
fast path's own test), sha256 content-hash compare only on stat mismatch
(so a touch/identical rewrite never false-positives), memoized briefly per
handler. On drift:

- codegraph_node: small files ship WHOLE and CURRENT (Read-parity, still
  no Read needed); large ones omit the body with an explicit notice
  steering to the tool's file-read mode or Read. Location/signature stay,
  flagged as possibly shifted.
- codegraph_explore: the whole-file render (already correct by
  construction) is kept and flagged; adaptive/skeleton/cluster slicing is
  disabled for drifted files — a too-big drifted file is omitted with a
  notice instead. The verbatim/do-not-Read header gains a per-file
  exception, and a trailing note flags shifted line references (flow,
  blast radius, symbol lists).

The guarantee itself is preserved: everything actually rendered is still
byte-accurate — drifted files ship whole or not at all, never as a
possibly-wrong slice. A re-sync of the target project restores normal
output (covered by test).

Adds __setLoadCodeGraphForTests (same seam pattern as __setFsWatchForTests)
so in-process tests can exercise a genuine cross-project open, which
vitest's transform cannot service through the lazy require.

02c0e2c935 fix(db): stop watchdog-killed sessions from leaking the SQLite WAL without bound (#1431) (#1490)
A SIGKILL'd process (the #850 liveness watchdog, OOM, a crash) leaves its WAL
on disk; the next session appends to the same file; and nothing ever truncated
it — PASSIVE checkpoints fold frames but keep the file at its high-water mark,
and the one shrinking path (a clean last-connection close) is exactly what a
killed-daemon world never takes. Observed at 25.6 GB on a 5.46 GB DB, growing
until the disk filled.

- journal_size_limit on every connection: resetting checkpoints now clip the
  WAL back to the cap instead of leaving it at its high-water mark.
- healOversizedWal() fired from every DatabaseConnection.open: off-thread
  PASSIVE fold + TRUNCATE when the leftover WAL exceeds the cap (64 MB,
  CODEGRAPH_WAL_HEAL_MB to override). Single-flight per connection with
  bounded retries — concurrent passes defeat each other (each checkpoint sees
  the other as a busy reader).
- Daemon/direct MCP watchdogs now pass progressPaths (DB + WAL), extending the
  #1231 slow-disk deferral to the long-lived server so a healthy daemon mid
  slow statement isn't SIGKILL'd — fewer kills, fewer leaked WALs.
- codegraph status shows WAL size (human + JSON) and warns when it dwarfs the
  DB; daemon.log lines and the watchdog kill notice now carry ISO timestamps
  so kills can be placed in time.

0682137a42 fix(installer): write the Claude prompt hook as codegraph.cmd on Windows (#1466) (#1489)
The standalone bundle's bin dir exposes only codegraph.cmd, and Claude
Code executes UserPromptSubmit hooks through Git Bash, which applies no
PATHEXT — so the bare `codegraph prompt-hook` the installer wrote was
"command not found" (exit 127) on every prompt. Write the platform-correct
spelling, recognize both spellings on uninstall/opt-out, and self-heal an
installer-written entry from the other platform in place on install/upgrade
re-runs (npx/hand-edited variants stay untouched).

Reproduced and validated on the Windows VM: bare form exits 127 under Git
Bash on a standalone-only PATH, codegraph.cmd exits 0; full installer suite
(165 tests, including the new migration coverage) green on Windows + macOS.

YucandGitHub 572d22bfbe fix(installer): Codex TOML block finder preserves trailing array-of-tables siblings (#1351) (#1370)
The Codex installer's `findNextTableHeader` skipped `[[array-of-tables]]` headers instead of treating them as a block boundary, so any `[[...]]` block after `[mcp_servers.codegraph]` in ~/.codex/config.toml was silently deleted on install/upgrade/uninstall. Now treats both `[...]` and `[[...]]` as boundaries, with a small line lexer so header-shaped text inside multiline strings/arrays isn't mistaken for a boundary. Adds round-trip regression coverage (install → reinstall → uninstall) + CHANGELOG entry.

Fixes #1351. Supersedes #624.

Thanks @KtzeAbyss.

c74e8b05e0 perf(sync): adaptive quick-fire debounce + scoped watcher sync — save-to-graph well under a second at any scale (#1397)
Two changes to the watcher path (the always-on daemon every agent
session uses), which previously paid a flat 2s debounce plus a full-tree
scan-diff on every save even though the OS events name the exact files:

1. Adaptive debounce: a pending set of ≤2 files fires after a 300ms
   quiet window; ≥3 keeps the full configured window so agent
   multi-file bursts coalesce exactly as before. Re-arming preserves
   trailing-edge semantics; a user-set CODEGRAPH_WATCH_DEBOUNCE_MS
   remains the authoritative upper bound (quick window never exceeds
   it, floor 100ms).

2. Scoped sync: watcher-triggered syncs pass their pending paths, and
   the reconciler stats exactly those — per-path logic identical to the
   full walk (stat pre-filter, hash confirm, the #1240
   removal/resurrection flow) — skipping the O(repo) scan and
   tracked-load. Strict fallbacks keep the full scan-diff as ground
   truth: directory removals (#1285 — the events can't name the
   children), empty pending sets (retry paths), and >500-file storms
   (branch checkouts, which also self-heal anything event coalescing
   dropped). filesChecked counts examined PATHS so a deletion-only
   scoped sync can't mimic the #449 lock-unavailable signature.

Measured (warm in-process, the daemon path): dubbo one-file sync work
512→335ms, Swift compiler (27k files) 884→385ms — save-to-fresh-graph
≈0.6-0.7s end-to-end including the quick debounce, from ~2.5-6s
perceived before. Gates: scoped-vs-full dumps byte-identical on dubbo
AND the Swift compiler; watcher suite 30/30 (3 new: scoped pass-through,
dir-removal fallback, quick-fire timing); sync suite 34/34 (4 new
scoped-parity cases incl. delete-resurrection and the lock signature);
full suite 2,696 ×2 with CODEGRAPH_KERNEL_EXPECT=1.

157c8e735d perf(resolution): generation-tagged supertype memo + method owner index — Swift compiler 185→98s, byte-identical (#1395)
The swiftc =2/nm:mc-* attribution located the wall: the
getSupertypes conformance walk ran 971,200 times (565s of combined
worker time, 581µs each) — every resolveMethodOnType miss re-queried
implements/extends edges for every same-named type node, recursing
depth-4 through Swift's protocol landscape with no memoization, and
post-inference resolveMethodOnType averaged 1,912µs per call.

Fix 1 — generation-tagged getSupertypes memo. Supertype edges GROW
during the resolution loop (batch k persists its edges BEFORE batch
k+1 fans out — the #1320 ordering), so a plain cache would freeze an
early batch's emptier answer. Within a batch the edge state is fixed
by that same ordering, so memo entries carry a generation that
advances at every batch entry point (resolveBatchYielding /
resolveListForAdmission — covering the sequential loop, pool workers,
sync admission, and the conformance pass); a stale-gen entry
recomputes. Behavior-identical to no memo at every point in time;
walk invocation counts match the unmemoized run exactly (971,200 /
24,336 / 76,415).

Fix 2 — per-(language, method-name) owner index in getMethodMatches:
candidates bucket once by their qualifiedName's last two segments
(exactly the span the match predicate tests), so a (type, method)
query is a map lookup instead of an O(candidates) scan per
methodMatchCache miss. ObjC selectors and multi-segment typeNames
keep the legacy linear path. Also ships nm:mc-rmot / nm:rmot-supers
=2 attribution rows.

swiftc: settle 100.2→31.3s, resolveMethodOnType 1,912→202µs, wall
183.5→97.8s (was 185s at the head-to-head; cbm's same-box number is
119.1s). Gates: swiftc old-vs-new dump byte-identical (1,837,235
rows), swiftc pooled-vs-CODEGRAPH_NO_PARALLEL_RESOLVE=1 identical
(the generation-semantics risk surface), dubbo old-vs-new identical
(49k Java instance-method hits share both paths), Alamofire
identical; suite 2,689 ×2 with CODEGRAPH_KERNEL_EXPECT=1.

974e6c8b95 perf(resolution): incremental receiver-inference scan memo + compiled-pattern memo — kong −8% more (−23% cumulative), byte-identical (#1392)
The kong/tokio matcher-chain residue attributed (nm:mc-* sub-stage rows,
shipped here too): matchMethodCall's cost is ~entirely
inferLocalReceiverType — 61µs per miss on kong, 99% miss rate (39k `self:`
calls hunting a local declaration Lua never writes), re-scanning the same
scope lines for every ref.

Two pure memos, both semantics-preserving by construction:
- Compiled-pattern memo: localReceiverTypePatterns/phpPropertyTypePatterns
  built 2-4 fresh RegExp objects per call; patterns are a pure function of
  (language, receiver) and non-global, so instances are shared via a
  FIFO-capped map (no per-get mutation — the §7a.6 LRU-churn lesson).
- Incremental scan memo: refs for the same (file, scope, receiver) arrive
  in ~ascending line order and the backward declaration scan is a pure
  function of immutable file lines — a per-context watermark scans each
  line once per key (query(c) = highest match in [start..c]; monotonic
  calls extend the watermark over (hi..c]; non-monotonic calls fall back
  to the plain bounded scan). componentScoped (CFML/PHP whole-file sweep)
  is keyed out. States drop with the context's file caches via
  clearNameMatcherMemos, wired into ReferenceResolver.clearCaches.

kong mc-infer misses 61→20µs (2.4s→0.8s combined); fresh index 3.43 →
3.03-3.20s (−8%; 4.07 → 3.14 cumulative with #1391). tokio unchanged
(tight scopes). Gates: dubbo (49k Java instance-method HITS ride this
scan), kong, tokio, Fusion dumps all byte-identical; suite 2,689 ×2 with
CODEGRAPH_KERNEL_EXPECT=1.

abb0a916f7 perf(resolution): per-context basename index for Lua/Luau require resolution — kong fresh index −16% (#1391)
The full-README competitor matrix ranked lua/kong as the largest
legitimate fresh-index gap (2.71×). Stage attribution (RESOLVE_PROFILE=2)
pinned it: resolveLuaRequire ran getAllFiles().filter(endsWith) FOUR
times per require ref — ~7.5k string suffix scans each, measured at
~0.9ms/ref, hit or miss (2.7s combined over kong's 3k requires).

Replace the per-ref full-list scans with a per-context basename →
file-paths index (the cobolCopybookIndexes pattern). Buckets preserve
getAllFiles() iteration order, so each suffix's candidate filter yields
exactly the array the full scan produced — identical matches, identical
stable sort, identical winner, dump-proven.

kong: 4.07-4.27 → 3.40-3.63s (−16%). Gates: kong old-vs-new dump
byte-identical (157,650 rows), kong pooled-vs-sequential identical,
Fusion (luau instance-path requires) old-vs-new identical; suite
2,689 ×2 with CODEGRAPH_KERNEL_EXPECT=1.

Also registers cobolCopybookIndexes in clearImportResolverMemos — it was
never dropped on cache clears, so post-sync copybook lookups could serve
a stale file list; cache-drop is the always-safe direction.

1aa4de6eaa perf(resolution): adaptive pool engagement — projected-settle bar replaces the fixed 150k-ref gate for mid-run boot; tokio −23% (#1390)
The 9-language competitor matrix exposed tokio as the worst fresh-index
gap: 77% of its wall was resolution running SEQUENTIALLY — 56k Rust refs
sit under the fixed 150k pool gate while costing 36µs each (9× Go's
4µs/ref on prometheus). A ref-count gate can't see per-ref cost.

After each sequential batch the loop now projects the remaining
sequential settle from the measured rate and boots the pool mid-run when
it clears 400ms. The switch rides machinery that already existed: pool
boot is async and fan-out engages only when ready, admission order is
mode-independent, and the #1320 edges-before-fanout invariant holds at
every batch boundary regardless of when the pool arrives. Up-front
engagement at >=150k refs is unchanged; 2-core/low-memory hosts still
decline inside tryCreate's sizing; CODEGRAPH_NO_PARALLEL_RESOLVE still
disables; downgrade permanence is preserved (one engage attempt per run).

Measured (n=3, interleaved, caffeinated): tokio 3.06-3.12 → 2.40-2.57s
(resolution 2,443→~1,330ms); express (tiny control) unchanged with zero
engagements; dubbo unchanged (ref-count path). Gates: tokio + excalidraw
adaptive-vs-sequential dumps byte-identical (87,302 / 89,903 rows),
dubbo dump identical to the session baseline, suite 2,689 ×2 with
CODEGRAPH_KERNEL_EXPECT=1. Known follow-up: sampling the rate mid-first-
batch would close the remaining ~0.3s to the forced-engage ceiling.

082ea65f3a perf(synthesis): provably-empty pass gates + prefilters — render/expo/rn/mybatis stop scanning repos they can't match; iface memo (#1389)
Store-arc round 2 (#1388 follow-up). The synthesis pool barrier on dubbo
carried ~1.4s of passes that provably could not emit an edge for the
project: reactRenderEdges fanned out over every class before checking for
a render method (now: one indexed name lookup bounds candidates — not a
language gate, Java Litho-style render+setState still matches);
expo/rn cross-platform pairing streamed every method row without the
languages their edges require (now registry-gated: expo needs swift AND
kotlin file-languages, rn needs a JS-family caller for isBridge);
mybatis built its full java-method index before discovering there were no
mapper-XML methods (now collects the XML side first). ifaceEdges — real
work — stops re-fetching a hub interface's methods once per implementer
and skips supertype-less classes before any per-class lookup.

dubbo warm wall 8.49-8.79 → 8.14-8.24s (n=3/arm, caffeinated); barrier
784→435ms; the full removed pass work lands on low-core envelopes where
synthesis runs sequentially. Dumps byte-identical: dubbo old-vs-new,
pooled-vs-sequential, kernel-vs-wasm (441,270 rows) + excalidraw JSX-live
control (89,903 rows, 46 react-render edges reproduced). Suite 2,689 ×2

CODEGRAPH_RESOLVE_PROFILE=2 attributes per-ref time to resolveOne's
strategies (stage:*) and the name-matcher's sub-matchers (nm:*);
CODEGRAPH_SYNTH_TIMINGS now prints the store worker's decode-vs-SQL
split. Killed by measurement, recorded in the PR: import-failure negative
cache (both-outcome names exist — static imports resolve via
instance-method on jvm-miss), jvm-miss early return (1,939 later-strategy
edges), jsxEdges language gate (Java generics text produces jsx edges),
and §4d buffer→bind on Spring repos (extract() hook forces the decoded
path — kernel=0 bundles measured).

27c3c55436 perf(resolution): darwin-honest memory budget — vm_stat-based availability unstrangles the resolver pool on macOS (#1388)
Post-R7b store-arc round 1, found by the dubbo warm-wall decomposition
(the cbm bar): resolution's loop-stage profile showed settle=3.0s — the
main thread idling on TWO resolver workers on an 11-core Mac. Pool sizing
logged `size=2 (budget=1068MB)`: memoryBudgetBytes() falls back to
os.freemem() when uncontained, and macOS keeps RAM deliberately full of
reclaimable cache, so freemem reads ~1GB on a mostly-idle 64GB machine.
The memory term then capped the pool at 2 where the CPU term allowed 6 —
the macOS sibling of §7a.1's os.cpus() cpuset-blindness (that round fixed
the CPU term; this fixes the memory term).

Fix: darwinMemoryAvailable() reads /usr/bin/vm_stat once per sizing call
and reports free + inactive + speculative + purgeable pages — what
Activity Monitor calls available, the same reclaimable-inclusive
convention the Linux branch already uses by crediting inactive_file back.
Parse failure → null → freemem fallback; Linux/cgroup and Windows paths
untouched.

Measured (dubbo 4,402 files, warm, caffeinated, n=3 each): pool now
self-sizes to 6 (budget 5.7-6.3GB) — wall 8.62-8.83s vs 9.67-10.87s
baseline, resolution phase 6.9→5.3s, loop settle 3.0→1.9s. Matches the
CODEGRAPH_RESOLVE_WORKERS=6 probe exactly (probe-before-build). Dumps
byte-identical pool-6 vs sequential (441,270 lines). Second consumer
unblocked: the cFnPtr LRU cache cap no longer spuriously degrades to 128
on Macs (its full-cache tier is worth ~60s at kernel scale).

Suite: resolver-pool-sizing gains a darwin-gated reclaimable-pages test +
an off-darwin null pin; full suite 2,689 green ×2 with
CODEGRAPH_KERNEL_EXPECT=1.

d1b75a1a27 feat(kernel): R7b Dart walker — dart module, vendored-grammar-C d4d8f3e + wasm byte-copy vendor, dart default-routed (#1386)
R7b batch 4 #4 — the FINAL R7b language (docs/design/dart-kernel-port-checklist.md
is the authoritative quirk list). The fourth vendored-grammar-C language,
with a twist: production dart resolved its wasm from tree-sitter-wasms,
whose dart dependency is an UNPINNED github:UserNobody14/tree-sitter-dart —
a routine dependency update would have silently changed dart's grammar.
This PR byte-copies the shipping 0.1.13 artifact into src/extraction/wasm/
(VENDORED_WASM_LANGS += dart) and compiles the same-commit (d4d8f3e337d8)
parser.c/scanner.c in the kernel — table identity proven by the
kernel-grammar-parity row. crates.io tree-sitter-dart is the nielsenko
fork (different lineage) — rejected.

The center of gravity is THE SIBLING-BODY DOUBLE-WALK, reproduced
bug-for-bug: dart attaches every function/method body as a NEXT SIBLING of
its signature, and the TS walkers consume each body TWICE — once via
resolveBody (attributed to the function/method) and once via the enclosing
generic walk (attributed to the file/class). Duplicate local-function
nodes with the SAME id under different parents, duplicated
calls/instantiates refs, and file/class-attributed fn-ref twins all emit
in the exact observed interleave (a dedicated fixture pins the
duplicate-id rows; the bloc kind-census spot-check pins the counts).

Also preserved (probe-pinned): the extractBareCall selector matrix (the
first callTypes=[] language — cascades completely invisible, `?.` encodes
like `.`, the `ConfigT.load()` calls+references double emission with no
callee-of-call skip, capitalized-chain `Foo.create().run` re-encode,
const-object callee names); the constructor hooks (unnamed ctor skipped,
named ctors/factories renamed to the CTOR name with the class as
returnType, `@override (T) m()` record-misparse rescued by class-name
validation); operator methods minting `method "<anonymous>"`;
static_final_declaration constants via the visitNode hook while instance
fields mint NOTHING; the prefixed-return-type prefix bug (`other.OtherClass
f()` → returnType `other`); enum `with` mixins silent vs `implements`
working; anonymous extensions named after the ON type; deferred imports
invisible; named-argument callbacks NOT fn-ref-captured (the Flutter
`onPressed:` idiom — future accuracy PR, TS-side first); `async*`/`sync*`
NOT async; value-refs with the LIVE dart sibling-body pull and the
`$X`-vs-`${X}` interpolation asymmetry; dartdoc kept in all three comment
forms with the annotation-broken chain.

Gates: parity sweeps first-run 0-diff on shelf/bloc/flutter — 5,815 clean
files byte-parity, deferrals 10/21/1341 ≈ the survey's 10/21/~1340
(both-arm grammar reality: empty object patterns — the sealed-class
idiom — and unnamed `library;` dominate; --max-deferral 0.3); full-init
dumps byte-identical ×3 (shelf 7,959 / bloc 40,026 / flutter 1,855,319
dump lines); bloc per-kind node census identical across arms (the
double-walk duplicate rows survive the store identically);
kernel-dart-parity suite (7 fixtures + in-memory CRLF variants +
double-walk duplicate-id pin + generated-file skip pin + two defer pins);
full suite 2,688 green ×2 with CODEGRAPH_KERNEL_EXPECT=1.
DEFAULT_ROUTED += dart (20 langs — R7b COMPLETE).

bdd687b49f feat(kernel): R7b Scala walker — scala module, vendored-grammar-C master@0aca5d0a6f, scala default-routed (#1385)
R7b batch 4 #3 (docs/design/scala-kernel-port-checklist.md is the
authoritative quirk list). The third vendored-grammar-C language and the
biggest grammar in the tree (35MB parser.c): the vendored wasm is
tree-sitter/tree-sitter-scala master@0aca5d0a6f — a post-v0.26.0 generation
sync that is not a release (the 0.26.0 crate is 30 states BEHIND, so a
crate pin would be a silent downgrade). NO wasm change: production has
parsed with this exact revision since #91 — the kernel-grammar-parity row
(ABI 15, 26,650 states, 32 fields, id-by-id tables) is the whole alignment
proof.

Preserved bug-for-bug (all probe-pinned): the leak-through asymmetries —
extension methods mint NO nodes (first def's body calls leak to the
enclosing scope, later defs invisible, and the braced form resolves its
body field to the `{` TOKEN via first-match-wins field lookup → whole
extension invisible); anonymous `new T { … }` template_body members leak to
the enclosing scope (findAnonymousClassBody misses template_body); the
bodied-vs-bodiless class asymmetry (bodiless headers walk class_parameters
→ default-value calls emit FROM the class; bodied ones never see them) —
plus first-segment import names (`import com.example.C` → `com`), the
val/var hook keyed on the enclosing-definition NODE TYPE (object vals →
constants/value-ref targets, class/trait/enum/given vals → fields) with
consumed initializers, every def routed through extractMethod with the
top-level function fallback, nested defs in bodies minting NOTHING (the
inverse of kotlin) while body-local classes extract fully, curried
signatures keeping only the FIRST parameter list (type params win the
`parameters` field), enum cases positioned at the CASE node with invisible
params/extends tails, extends with-chains via scalaBaseTypeName,
`@deprecated(args)` decorates, the #750 capitalized-chain re-encode
(`WidgetS.create().render`), literal-receiver silence, static-member reads
AND writes, infix invisibility, `derives` silence, scaladoc retention with
the CRLF `\r` pin, full value-reference machinery (shadow prune, last-wins
same-name targets, `$X`/`${X}` interpolation reads), and SCALA_SPEC
fn-refs (bare ids + postfix eta unwrap + varinit, var-init non-capture).

Gates: parity sweeps first-run 0-diff on os-lib/cats/scala3-compiler-src/
scala3-library-src — 1,935 clean files byte-parity, deferrals 0/15/57/116
matching the survey's predictions exactly (scala-3's PHANTOM hasError
files — flag-true, zero ERROR nodes, capture-checking `^` — defer on the
FLAG); full-init dumps byte-identical ×3 (os-lib, cats, scala3 whole-repo
950,889 dump lines); kernel-scala-parity suite (9 fixtures + 9 in-memory
CRLF variants incl. Scala-3 indentation through the external scanner +
phantom/real-error defer pins + first-segment/namespace/value-ref pins);
full suite 2,669 green ×3 with CODEGRAPH_KERNEL_EXPECT=1
(kernel-scaffold's stays-wasm example moved scala → pascal).
DEFAULT_ROUTED += scala (19 langs).

e32135171e feat(kernel): R7b Lua+Luau walker — one lua module, vendored-grammar-C lua v0.4.1, tree-sitter-luau 1.2.0 pin, both default-routed (#1384)
R7b batch 4 #2 (docs/design/lua-luau-kernel-port-checklist.md is the
authoritative quirk list). ONE walker for both dialects (ccpp precedent) —
the differences are exactly four: luau's type_definition aliases, the
`export `-slice isExported hook, the return-type signature suffix, and the
grammar handle.

Grammar prep is kernel-side only, no wasm change: lua is the SECOND
vendored-grammar-C language (the vendored wasm is the v0.4.1 tag, a revision
not on crates.io — tag artifacts compiled via build.rs, shas pinned); luau
is a plain crate pin =1.2.0 whose tarball is sha-identical to the tag (the
swift tag≠crate divergence does not recur). Grammar-parity rows replace the
bump gate entirely.

Preserved bug-for-bug (all probe-pinned): the require/visitNode-hook
ASYMMETRIES (top-level requires — including inside top-level if/for/while —
mint import nodes while the identical body-level statement emits
`calls "require"`; top-level `local x = foo()` initializers are invisible
while global `x = foo()` calls emit), the BFS string-win inside require args
(`require(script:WaitForChild("Kid"))` → import Kid) and Roblox instance
paths, receiver-QN methods (`M.sub.deep::chained`, `_G::installed`,
stack-QN nested globals like `render::leakedGlobal`), the raw-text callee
world (colon forms with `self` never stripped, bracket callees,
newline-glued chains byte-verbatim, the `(handler)` paren-conversion),
LUA_SPEC function-as-value capture with the `M.cb = cb` param-storage skip
and first-occurrence dedupe, LuaDoc `---` keeping a leading `- ` plus
`--!strict` joining docstring chains (block-comment docstrings keep interior
CRLF bytes), variable nodes at the IDENTIFIER with positional value pairing,
duplicate same-(kind,name,line) ids, and the lua↔luau isExported wire
divergence (lua functions: flag absent; luau functions: present-false;
methods: absent in both; variables: present-false in both; `export type`:
true).

Gates: parity sweeps first-run 0-diff on kong/lazy.nvim/lua-resty-core
(lua) + lune/Fusion (luau) — 1,734 clean files byte-parity, deferrals
1/0/0/3/8 matching the survey's both-arm predictions exactly (kong's 1 = a
deliberately invalid fixture; luau's = grammar-inherent generic type packs
and default type params); full-init dumps byte-identical kernel-vs-wasm ×4

b2f9ab1800 feat(kernel): R7b R walker — rlang module, tree-sitter-r 1.2.0 crate pin, r default-routed (#1383)
R7b batch 4 #1 (docs/design/r-kernel-port-checklist.md is the authoritative
quirk list; survey + probe record therein). The lightest-shared-surface,
heaviest-hook port: languages/r.ts works entirely through the visitNode hook
(every type list empty except callTypes:['call']), so the walker is a file
node + a faithful hook transcription + the generic extractCall + pre-order
recursion — four shared machineries (value-refs, static-member reads, type
annotations, fn-ref capture) are dead by language gates and stay dead.

Grammar prep is the first true no-op of the arc: the crates.io tree-sitter-r
1.2.0 tarball ships parser.c AND scanner.c sha-identical to the r-lib v1.2.0
tag the vendored wasm was built from — crate pin only, no wasm change, no
bump gate; kernel-grammar-parity gains the r row (ABI 14, same-revision).

Preserved bug-for-bug (all probe-pinned): calls "return" on every return(x)
(named node in v1.2.0), the import quintet's silent dynamic-arg consumption
vs class/generic fall-through asymmetry, library(help = pkg) importing the
named arg, class-idiom variable suppression by callee name, chained/right-
assign/precedence-ghost gaps, env$fn body-leak-to-file, raw-text callees
verbatim (pkg::fn, obj$meth, "strfn" quotes kept, (handler) conversion),
duplicate same-(kind,name,line) ids, roxygen dropped entirely, UTF-16
columns/slices.

Gates: parity sweeps first-run 0-diff on AnomalyDetection/dplyr/ggplot2/
shiny (838 files; deferrals exactly 0/0/0/1 — the 1 is the moustache-
template pseudo-R file, both-arm) — kernel-parity.mjs gained lowercased-
extension matching so .R files sweep (matches detectLanguage routing);

45a53eb5b5 feat(kernel): R7b Kotlin walker — kotlin module, vendored-grammar-C build, kotlin default-routed (#1382)
Sixth R7b port — the T1½ batch finale. Checklist-first recipe
(docs/design/kotlin-kernel-port-checklist.md, 1,121 lines, dist-extractor
ground truth); parity passed FIRST RUN on all three repos.

THE NOVEL MECHANISM — vendored-grammar-C (the §4 tracker's prescription,
first use): the crates.io tree-sitter-kotlin 0.3.8 pins `tree-sitter >= 0.21,
< 0.23` (the kernel links 0.25) and tree-sitter-kotlin-ng is a DIFFERENT
grammar (8 fields vs 0, renamed kinds — extractor-breaking), so no crate dep
is possible. The fwcd 0.3.8 tag's sha-matched parser.c + scanner.c are
vendored into codegraph-kernel/grammars/kotlin and compiled by build.rs (cc),
exposed via tree-sitter-language::LanguageFn. The wasm re-vendor is
behavior-NEUTRAL (0 CST/error disagreements across 1,984 gate-repo files;
old-vs-new full-init dumps byte-identical ×3) — a reproducibility re-vendor,
ABI stays 14.

Walker firsts: extension-function receivers (getReceiverType →
`WidgetK::extend` QN OVERRIDE with no package prefix, the qualified-receiver
`com::qext` first-segment bug, and the owner-contains fallback that excludes
`interface` kinds and is source-order dependent) and extractModifiers
(expect/actual platform modifiers → the node DECORATORS wire field on every
created node — the KMP synthesizer's feed, incl. `actual typealias`).
Preserved bug-for-bug: the FIELD_COUNT-0 dead cluster (no signatures, ZERO
type-annotation refs), hook-consumed property initializers emitting nothing
(incl. `by lazy {}`), the bodiless-vs-bodied class header asymmetry, enum-
entry bodies being invisible, KDoc never a docstring AND chain-breaking,
comment-gluing into import/package extents, `@Anno(args)` emitting nothing
while `@Marker` decorates, zero instantiates refs, the paren-then-lambda
`trailing()` garbage callee, text-includes visibility/suspend false
positives, and the packaged-file value-ref target drop. The fun-interface
misparse-recovery hook is DEFER-SHIELDED (every such file has_error) and
deliberately not ported. The swift-sweep lesson pre-applied: the shared
`assignment` shadow-prune case is implemented alongside the
property_declaration case.

Gates: sweeps 0-diff okio 299/322, okhttp 531/580, kotlinx.coroutines
1031/1082 (deferrals exactly the predicted 23/49/51 — both-arm grammar
reality incl. PHANTOM hasError files with complete CSTs; the kernel trusts
the flag); full-init dumps byte-identical ×3 (46.5k/108.9k/92.3k lines); KMP
expect/actual synthesis IDENTICAL across arms (412 edges on
kotlinx.coroutines — the tracker's KMP validation); kernel-kotlin-parity
suite (torture reflowed off the phantom shapes + .kts script + CRLF variants
+ fun-interface and phantom defer pins) + kotlin grammar-parity row (the
C-build ↔ wasm table identity proof); full suite 2,633 green ×2 under

09e301bbfa feat(kernel): R7b Swift walker — swift module, tree-sitter-swift 0.7.3 bump, swift default-routed (#1381)
Fifth R7b batch-3 port, checklist-first recipe
(docs/design/swift-kernel-port-checklist.md, 1,056 lines — the largest of the
arc, with a built-extractor-validated emission pin and a childForFieldName
truth table).

Grammar bump first, validated standalone: tree-sitter-wasms ^0.4.0 (ABI 13) →
crate 0.7.3 — with a provenance twist: the wasm is built from the CRATE
TARBALL's src/ (alex-pinkus keeps generated files off main and the
0.7.3-with-generated-files tag ships an older ABI-14 generation that can never
sha-match; grammar.json rules are JSON-equal; the tarball is byte-for-byte
what the kernel's cargo build compiles — table identity by construction).
Older crates evaluated and rejected: clean-parse shapes are byte-identical on
0.7.3 (53-line CST battery diff, all inert), so an older pin buys nothing and
loses the macro-era wins. Delta = error-set membership (63 old-error files
parse clean: swift-testing #expect, #Preview/#GET macros, package access,
typed throws — vapor 23.1%→9.3%; 21 NEW-only regressions in 3 probed
construct classes) + two gate-found categories: docstring boundaries near #if
directives (7 clean files, docstring-field-only — verified mechanically) and
array-literal-callee call refs (2 refs, 1 file). Every hunk classified via
the error-union rule + parked-ref↔edge ripple pairing.

Walker (the arc's biggest) centers on the #1020 DEDICATED property branch:
computed properties → property nodes with the getter walked under the
property (SwiftUI body), static let/var → constant/variable, stored → field,
decorator/type-annotation/@Siblings-attr-arg refs all attached to the
ENCLOSING TYPE, stored initializer calls attributed to the class. Preserved
bug-for-bug: the never-resolving 'parameter' field (zero param type refs,
zero signatures), present-false isAsync, open→internal visibility,
everything-is-extends inheritance (first type_identifier per specifier), no
instantiates refs ever, subscript reads as `calls arr`, `defer` as `calls
defer`, multi-case enum entries minting only the first case, /** */ block
docs ignored AND chain-breaking, init/deinit/subscript minting no nodes with
visitNode-routed bodies (calls → class, static reads → nothing), multi-
segment extension resolveName, sugar extension names, the #selector shapes,
and the value_argument label-forward skip. ONE fix found by the sweep (then
pinned in the fixture + checklist): the shared `assignment` shadow-prune case
is swift-live — declared-then-assigned `let X: T` prunes X as a value-ref
target.

Gates: sweeps 0-diff Alamofire 89/98, vapor 224/247, swift-nio 407/554
(--max-deferral 0.3 — swift error incidence is 9–27% on BOTH arms,
structural; every deferral count matches the survey's table exactly);
full-init dumps byte-identical ×3 (31.9k/20.7k/126.3k lines); the Alamofire
census reproduces property=348 (the #1020 number) on the kernel arm;
kernel-swift-parity suite (206-line torture + CRLF + the #if-between-enum-
cases defer fixture) + swift grammar-parity row; full suite 2,626 green ×2
under CODEGRAPH_KERNEL_EXPECT=1. DEFAULT_ROUTED += swift (14 langs).

a6c62d77df feat(kernel): R7b PHP walker — php module, tree-sitter-php 0.24.2 bump, php default-routed (#1380)
Fourth and final R7b batch-2 port, checklist-first recipe
(docs/design/php-kernel-port-checklist.md).

Grammar bump first, validated standalone with the diff ENUMERATED + CLASSIFIED
(unlike rust/ruby the php bump is NOT graph-neutral): tree-sitter-php ^0.22
(tree-sitter-wasms, 2023) → v0.24.2, the full HTML-interleaving `php` variant
(the walker calls LANGUAGE_PHP, never PHP_ONLY) — crate pinned =0.24.2, wasm
built from tag 5b5627f's checked-in php/src/parser.c + scanner.c + shared
common/scanner.h (all sha-matched against the crates.io tarball, ABI 14→15).
Old-vs-new full-init diffs decompose completely into: (1) the anonymous_class
wrapper shape (anon-class nodes/methods re-shape — 2,532 rows), (2) grouped
nested-clause skip (absent in the gate repos, fixture-pinned), (3) 32
formerly-erroring files parsing clean (monolog Level.php, symfony
Request/Response with 8.4 property hooks), (4) a survey-missed category found
at gate time: the 8.4 parenthesis-free `new X()->m()` chaining misparse fix
(86 garbage instantiates refs disappear, precision-positive), plus resolution
RIPPLE proven mechanically (every remaining ref-table flip pairs 1:1 with a
resolved edge on the opposite side; node rows byte-stable outside 1/3/4).

Walker (java.rs chassis + the php specifics) preserves bug-for-bug: the
visitNode hook (const_declaration at ANY scope → bare `constant` nodes, values
never walked; trait-use → implements refs WITH filePath via the ruby port's
REF_FLAG_FILE_PATH wire slot), FIRST-namespace whole-file scoping (braced
namespaces scope nothing; namespaced files DROP top-level const value-ref
targets), the import trio (single/aliased/grouped incl. the nested-clause
skip, include/require static-literal-only, `Foo\Bar::Baz` use refs), the
call-encoding zoo (DOT-joined scoped calls, `this->prop.m` #1251 encoding,
`Cls::factory().m` fluent with inner args dropped, nullsafe `?->` emitting
nothing, unsuppressed literal receivers), interface multi-extends
first-base-only drop, anon-class methods as file-level functions (top) or
vanishing (in-body), property type-hints emitting no field refs, the
final-modifier-as-type signature quirk, HOF-gated string callables
(skipGate) + array callables, and the `name`-node value-ref reader.

Gates: sweeps 0-diff monolog 217/217, laravel-framework 3007/3008, symfony
10726/10737 (13,950 files byte-parity; 12 deferrals = exactly the predicted
genuinely-broken fixtures, ≈0–0.1%); full-init dumps byte-identical ×3

1909931238 feat(kernel): R7b Ruby walker — ruby module, tree-sitter-ruby 0.23.1 bump, ref-flag wire slot, ruby default-routed (#1379)
Third R7b port, checklist-first recipe (docs/design/ruby-kernel-port-checklist.md).

Grammar bump first, validated standalone (the rust pattern): tree-sitter-ruby
^0.20.1 (tree-sitter-wasms, 2024-02) → v0.23.1 — crate pinned =0.23.1, wasm
built from tag 71bd32f's checked-in parser.c/scanner.c (both sha-matched
against the crates.io tarball; content bump, ABI stays 14). Old-vs-new
full-init dumps: sinatra/jekyll byte-identical; rails = exactly the one
classified hunk (the `recv&.!=` safe-nav operator misparse fix,
`table_name.!` → `table_name.!=`, precision-positive).

Walker (python.rs chassis + the six ruby divergences) preserves bug-for-bug:
the importTypes:['call'] funnel (class-body DSL — attr_accessor, has_many,
define_method incl. its block, sinatra route blocks — emits NOTHING at
non-body scope), hook-handled module multiply-capture (nested modules re-scan
their subtree per level after popping — `this.hooked` fn-refs from class AND
module AND file), the sibling-scan visibility trio (bare `private` invisible;
`private :sym`/`private def` poison all later defs; the inner def stays
public), bare-call statements (do…end body_statement emits, brace-block
block_body doesn't), `.new` instantiates with last-`::`-segment names,
constant-receiver references refs, require/require_relative path refs
(posix-normalized, `.rb`-suffixed, `Kernel.require` and interpolated-path
quirks included), `=begin` docstring marker survival, and the reverse-order
value-ref DFS.

Wire v2: the hook's mixin `implements` refs carry `filePath: ctx.filePath` —
the ONE extraction-ref denormalized field (php's trait-use refs share the
shape). RefRow's first pad byte becomes a flags slot (REF_FLAG_FILE_PATH);
decode re-attaches its own filePath parameter; KERNEL_ABI_VERSION 1→2 on both
sides (mismatched dist/.node pairs degrade to wasm, as designed).

Gates: sweeps 0-diff sinatra 147/147, jekyll 164/164, rails 3452/3452 (3,763

286e9ccc2d feat(kernel): R7b C# walker — csharp module, tree-sitter-c-sharp 0.23.5 pin, csharp default-routed (#1378)
Second R7b port, checklist-first recipe (docs/design/csharp-kernel-port-checklist.md;
parity passed FIRST RUN again). No grammar bump — the #717 vendored wasm verified
table-identical to crate 0.23.5 (ABI 15, STATE_COUNT 8053, node-kind + field tables);
first port with no grammar-prep step. The #237 #if-blanking preParse stays TS-side
via the existing route-point hoist.

Walker preserves bug-for-bug: the single-namespace-node quirks (second namespace
nests under the first, nested namespaces leave no trace, import refs hang off the
namespace node), raw member-access callee texts (this./base./literal receivers,
multi-line fluent chains) with unconditional chain re-encode, deliberate emission
holes (property accessor/expression bodies, ctor initializers, delegates/events/
operators/indexers/local functions, top-level locals), garbage extends refs
((repo) primary-ctor args, BaseDto(Name) record bases, enum : byte), the alias-
import moduleName quirks, nameof-as-call, CSHARP fn-ref spec (+= subscription,
this.X bare-name form, argument layer, initializer lists), C# type-ref engine
(nested-generic returnType failure included), and value-ref shadow pruning.

Gates: sweeps 0-diff serilog 211/216 / Newtonsoft.Json 914/945 / jellyfin

f1ca991943 feat(kernel): R7b Rust walker — rustlang module, tree-sitter-rust 0.24.2 bump, rust default-routed (#1371)
First R7b language port. Grammar: tree-sitter-rust pinned =0.24.2 + wasm
vendored from tag 77a3747 (parser.c/scanner.c sha-matched against the
crates.io tarball), replacing the 2023 ABI-14 tree-sitter-wasms build —
the bump alone is precision-positive on the wasm path (receiver-qualified
instance-method resolutions replace ambiguous bare-name matches; node
sections byte-identical on ripgrep/tokio).

Walker mirrors the TS reference bug-for-bug per
docs/design/rust-lang-kernel-port-checklist.md (survey artifact): dead-code
isAsync, impl-pushes-no-scope, the impl-Trait-for-Generic<T> trait-receiver
quirk, phantom const identifiers, use-binding triple emission,
wildcard-use-emits-nothing, scoped-supertrait drop, chained-call re-encode
gated on scoped_identifier, Rocket route macros body-only.

Gates: parity sweeps 0 diffs — ripgrep 101/101, tokio 790/790,
rust-analyzer 1217/1488 (271 deferrals are token-macro-table sources that
error on BOTH arms — grammar-inherent); full-init dump-diffs byte-identical
on all three (3,857 / 13,440 / 39,030 nodes); kernel-rustlang-parity suite
(torture + CRLF + defer) in npm test; full suite green x2 with
CODEGRAPH_KERNEL_EXPECT=1.

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).

f6d8e8fdab perf(store): parse-lane index deferral — dubbo fresh init −19%, kernel-scale envelope best-ever 14.2min (§4d round 1) (#1368)
Store-architecture arc round 1 (the cbm speed bar: dubbo warm wall
10.7-11.2s vs their ~7.5). §4d measured dubbo's parse-loop as 94%
store-writer busy with B-tree maintenance as the floor (statement
batching and sorted inserts already killed at ~zero). This applies the
resolution phase's proven edge-index window to the whole parse lane:

beginBulkParseLoad/endBulkParseLoad on DatabaseConnection — FRESH-INIT
ONLY (incremental runs delete per-file rows through the file_path
indexes) — drop all 15 nodes/unresolved_refs/files secondary indexes
plus the 4 non-unique edge indexes for the parse phase's mass insert
(the UNIQUE edge identity index stays: OR-IGNORE dedup conflicts on it,
and its source prefix keeps mid-window reads indexed), then rebuild
each in one table scan before resolution, with a yield between builds
(the endBulkEdgeLoad watchdog rationale). A crash inside the window
heals on the next open — schema.sql re-applies CREATE INDEX IF NOT
EXISTS.

Measured:
- dubbo (cbm bar repo): parse-loop 4,306 → 1,787ms (−58%), rebuild
  665ms, warm fresh-init wall 10.5-11.3 → 8.46-9.39s (−19%); the bar
  gap vs cbm shrinks from ~3s to ~1.1s.
- Linux kernel 8c: envelope ≈ 14.2min, best ever (prior 14.8). Parse
  itself flat (linux parse is extraction-bound, not writer-bound) and
  the rebuild costs 21.6s — but every downstream phase dropped
  (resolution 517-589 → 423.4s, edge-recreate 36.5s, synthesis 157.1s,
  maintenance 16.3s): bulk-rebuilt B-trees are densely packed where
  incrementally-grown ones are fragmented, so every index-mediated read
  for the rest of the run pays fewer pages.

Gates: dubbo/gson/express/excalidraw full dumps byte-identical
(dubbo's canonical 441,270 lines reproduced); 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). Incremental
sync paths untouched by construction (freshDb gate).

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).

b9d0f57a64 feat(extraction): C deferral round 2 — 8 new preParse passes, linux kernel/+mm/ deferral 58.6%→33.9% (#1353)
Census-driven cut of the top-ranked post-R7a lever. All passes TS-side,
C-only (preParseCSource), shared by both arms:

- parameterized-annotation whole-blank (__free/__printf/__counted_by/
  __bpf_md_ptr…; extends through a stranded field `;`)
- type-keyword-arg scanner (kzalloc_obj(struct T), list_entry, multi-line
  continuations behind nested-paren args; bounded hand scanner, head
  exclusions + call-vs-declaration guard; blanks trailing stars)
- static/extern CAPS-macro declaration lines at any scope; the initialized
  form is REWRITTEN to its expansion (name/tail keep exact offsets)
- va_arg qualified-type blank; GNU named-variadic #define dots-only blank
  (post-restore); sandwiched notrace-family; C23 auto; multi-line
  iterator-macro spans (hlist_for_each_entry_rcu + lockdep arg)
- word list += cacheline family (2- and 4-underscore spellings) + 10 more
  census-confirmed annotations

Gates: five-repo parity sweeps 0 diffs (git deferral 16.1→12.2%, redis
25.3→24.1%, fmt/protobuf unchanged); linux full-tree both arms
2,049,153 nodes / 6,413,518 edges (+858/+6,585 vs R7a) with byte-identical
dumps (10,446,478 lines, sha256 6dd1185b); kernel-arm parse-loop 356→306s
at 2c; suite 2517 green under CODEGRAPH_KERNEL_EXPECT=1. Honesty note
recorded in the docs: error recovery was already salvaging most SYMBOLS on
deferred files — the graph win is relationships + phantom cleanup, and the
unreleased CHANGELOG entry was rewritten off the sweep-subset framing.

Also records §7a.5: post-R7a 8-core cg1212 re-run 16.4min (was 18.3min);
8c parse sits on the single-writer floor, so the <10min-on-8c gap re-ranks
to the per-ref resolution path.

Parity: 0 diffs on redis/git/fmt/protobuf/ALS sweeps; full-init dumps
byte-identical on all five + linux at kernel scale (10.4M dump lines,
same sha256 both arms). Linux 2c/6GB envelope: kernel-arm 19.1min vs
wasm-arm 22.9min (parse 356s vs 435s) on a much richer graph (the new
blanks recover error-swallowed code: git 2x nodes, linux kernel/+mm/ 3x).
Deferral guard corrected by measurement (C/C++ error incidence 9-42%;
--max-deferral flag); defer-reuse memo kills the 3x re-blank/re-parse
cost deferred files paid.

44561b6aad feat(extraction): vendor current C/C++ grammars (R7a prep) — c v0.24.2 + cpp v0.23.4, sha-matched (#1345)
tree-sitter-wasms shipped 2023-era C/C++ grammars; the kernel walker must
compile the crates.io versions, so production wasm upgrades FIRST and in
isolation (the R2 pattern). Built with tree-sitter-cli 0.25.10 from each
tag's CHECKED-IN parser.c: tree-sitter-c v0.24.2 (b780e47, parser.c
f2883ff9), tree-sitter-cpp v0.23.4 (f41e1a0, parser.c 2a35a43b, scanner.c
cf60387d) — sha-matched against the crates.io tarballs. .metal/.cu map to
language 'cpp' so the dialects ride the same coherent grammar.

Full suite green with the upgraded grammars (2,490; one unrelated daemon
idle-timeout flake passed solo 9/9) — incl. the UE-macro, misparse-guard,
Metal, and CUDA coverage. Checklist updated with the vendored revs and the
metal/cuda routing correction.

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.
