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.

Step 1 of the §0a recipe for the C/C++ port: every tree-sitter.ts branch,
extractor-config field, name-salvage helper, and gate the walker must
mirror, with file:line anchors. Locks the architecture: preParse (all seven
blanking passes) hoists to the kernel route point so none of it ports to
Rust; Metal/CUDA stay on wasm this round; one dual-language walker module.
Key asymmetries surveyed: value-refs are C-only (cpp absent from
VALUE_REF_LANGS), static-member refs are cpp-only, fn-ref spec is
cFamilySpec with addressOfOnly for cpp.

On CRLF checkouts (every Windows autocrlf clone) the JS reference's
block-continuation strip /^\s*\*\s?/gm finds a line start after the \r and
its greedy \s* consumes the \n, leaving a bare \r in the docstring; the
kernel's (?m)^ pass matched after \n only and kept \r\n. Caught by the O2
Windows VM leg (6 kernel-tsjs-parity failures), reproduced on macOS by
CRLF-converting the fixtures.
js_multiline_strip now replicates the JS anchor set (\n, \r, U+2028, U+2029)
for all five line-marker passes; CRLF variants of every torture fixture are
pinned in kernel-tsjs-parity, derived in-memory so nothing can normalize
them away.

R1-R6 are done; §0 is now the open-work list in recommended order
(merge → Windows VM leg → P1 resolution → C/C++ port → long tail), and
§0a carries everything a fresh session needs: where the work lives, the
build/gate commands, the proven add-a-language recipe, and the paid-for
traps (encoding-dependent error recovery → defer policy, node-ID-string
dedupe, UTF-16 positions/slices, the exact-seam contract, crate+wasm
grammar lockstep). §1/§6 keep the original expectations with SUPERSEDED
annotations pointing at the measurements that corrected them; §7a now
carries the R6 numbers that make it the top open perf item.

cg1212 (Linux kernel, 2 CPU/6GB): completes in 26.4min vs the ~27min
baseline with all new machinery active — no regression; graph scale
identical (2,048,664 nodes / 6,405,964 edges). The §6 parse expectation
(6m → ~2m) was mis-premised: the tree is ~99% C, an unported T2
language, so it transfers to the C/C++ port (R7). Resolution remains
the kernel-scale wall (19.2m, 73% — P1). The tree's own Python tooling
files: 99/99 byte-parity. kernel-parity.mjs now skips dangling
symlinks (Linux dtc fixtures).

Python (codegraph-kernel/src/python.rs) and Go (src/go.rs) join the
native kernel, mirroring the wasm extractors bug-for-bug. Python:
decorated_definition docstrings/decorators (decorates refs only for
bare-identifier decorators — the call-kind quirk), function-in-class →
method, module-level assignments always extract as variable, from-import
per-name binding refs, self.x fn-ref candidates as bare names. Go:
receiver methods with Recv::name qualified names + contains edges to the
first earlier struct of that name, type_spec struct/interface
classification with embedding→extends and interface method nodes,
composite-literal instantiates keeping the package qualifier, top-level
var/const initializer walks attributed to the declared symbol (#693),
2-hop field chains (#1276), New().Method() re-encode (#645/#608), and
the GO_SPEC fn-ref layers.
Grammars: tree-sitter-python 0.23.6 + tree-sitter-go 0.23.4 crates, with
wasm vendored from the same tags (parser.c sha-matched) — both were
2023-era in tree-sitter-wasms.
Gates: extraction sweeps 100% (flask 83/83, django 3,035/3,038 +3
error-file deferrals, gin 99/99, prometheus 978/979 +1); full-init
dump-diffs byte-identical on flask (10,833 rows), gin (17,540), django
(360,794), and prometheus (213,758); torture fixtures enforced in npm
test. DEFAULT_ROUTED now covers typescript/tsx/javascript/jsx/java/
python/go. Full suite: 2,471 tests pass.

Kernel-routed files ship their flat tables from the parse worker to the
store worker as buffers (tryKernelExtractRaw → kernelBuffers on the
result → KernelStoreBundle); the store worker decodes and finalizes
(finalizeStoreBundle shared with the object path so filter semantics
can never drift). Files with applicable framework extract() hooks keep
the decoded path; the no-writer fallback materializes via
materializeKernelResult. Byte-identical dumps re-verified on dubbo,
excalidraw, express, gson; full suite green (2,467).
Measurement (plan §4d): dubbo's parse-loop wall is 94% store-writer
busy time — the many-core fresh-index wall is single-writer SQLite
ingest, not extraction or main-thread work. d2s improves the writer
lane ~11% (structured-clone deserialization avoided on the writer) and
frees the main thread; the remaining many-core gap is a
store-architecture arc (deferred index builds, multi-file
transactions, buffer→bind), out of the kernel project's scope.

Java joins the native kernel (codegraph-kernel/src/java.rs), mirroring
the wasm extractor's Java paths bug-for-bug: package namespaces,
imports, javadoc, annotations→decorates, type_list inheritance,
static-final constants, enum constants, anonymous classes (including
the TS side's 0-based-line quirk on the extends ref), method_invocation
calls with the this.field unwrap and the Foo.getInstance().bar() chain
encoding (#645/#608), static-member value reads, method-reference
fn-refs (#756), value-reference edges, and the full Lombok member
synthesizer (#912: Getter/Setter/Data/Value/Builder/ToString/
EqualsAndHashCode/Slf4j-family with taken-member dedup). The shared
docstring/textutil modules moved to crate level. Grammar:
tree-sitter-java 0.23.5, with the wasm grammar vendored from the same
tag (parser.c sha-matched) replacing tree-sitter-wasms' 2023-era build.
Gate (plan §4c): extraction sweeps 100% — gson 262/262, retrofit
341/341, dubbo 4,048/4,048 — plus a Java torture fixture in npm test;
full-init dump-diffs byte-identical on gson (49,766 rows), retrofit
(62,735), and dubbo (441,266 rows); all R2/R3 repos re-verified; Linux
container runs all 23 kernel tests green under CODEGRAPH_KERNEL_EXPECT=1.
The gate caught a real cross-language bug: fn-ref dedupe and value-ref
self-target checks must compare node ID STRINGS, not node-table rows —
ids collide for same-(kind, name, line) nodes, which minified one-line
bundles hit routinely (retrofit's website JS exposed it; latent in the
TS/JS walker since R2, never released). Fixed in both walkers.
Benchmark honesty: dubbo fresh-init on an 11-core Mac is ~flat
(parse-loop wall 5,020→4,394ms; total ~11.3s both arms) because that
wall is main-thread-bound (reads + store), not worker-CPU-bound — the
§6 expectation assumed otherwise. Where worker CPU binds the kernel
delivers: dubbo on a 2-CPU/6GB container drops 27.8-28.6s → 22.3-22.8s
(~1.25×). The identified lever for the many-core headline is decoding
kernel buffers directly into store rows (skipping per-node JS object
materialization); the buffer contract already carries everything.
DEFAULT_ROUTED now includes java. Full suite: 2,467 tests pass.

Gate evidence (docs/design/rust-kernel-migration-plan.md §4b):
- Graph parity, byte-identical (stronger than the §5 ≤0.5% bar): full
codegraph-init dump-diffs kernel-vs-wasm on express (13,712 rows),
excalidraw (89,898), and vscode (2,378,238 rows) — identical bytes.
Python control repo (flask) identical + timing unchanged. The parity
harness is now ORDER-sensitive (emission order drives rowids, which
drive resolution order) and dumps come from the new
scripts/dump-graph.mjs (natural keys, no rowids/timestamps).
- The one real find, caught by the vscode tier: tree-sitter error
RECOVERY is encoding-dependent — byte-identical grammar sources and
the same core (0.25.10) recover erroring files differently under
UTF-8 (native) vs UTF-16 (web-tree-sitter) parsing; proven by
reproducing the wasm tree with a native UTF-16 parse. Policy: the
kernel defers any file whose tree has_error() to the wasm extractor
(silent 'defer:' signal, per file) — parity by construction on
erroring files (incidence 0-0.42% across the gate repos), and the
harness fails if deferrals exceed 10% so a broken kernel can't hide
behind the fallback.
- Retrieval invariants: canonical excalidraw flow (mutateElement →
renderStaticScene) connects end-to-end on the kernel-indexed graph;
synthesized-edge families present. Agent A/B is vacuous under
byte-identical DBs (same justification as #1320-#1322).
- Perf: vscode init 105.4s → 82.1s (1.28×) on an 11-core Mac;
excalidraw on a 2-CPU/6GB Linux container (the CI-runner envelope)
6.2-7.1s → 4.3-4.8s (~1.5×). Linux arm64 in-container build: all 22
kernel tests green under CODEGRAPH_KERNEL_EXPECT=1. Windows VM leg
deferred (VM stopped; prlctl start needs Parallels Pro) — benign: a
missing .node falls back to wasm, and the release matrix builds and
gates the win32 prebuilds.
- Full suite: 2,465 tests pass WITH default-on routing, so the entire
extraction corpus now exercises the kernel for TS/JS wherever a
.node is staged.
DEFAULT_ROUTED = {typescript, tsx, javascript, jsx}. Override:
CODEGRAPH_KERNEL_LANGS (replaces the set) / CODEGRAPH_KERNEL=0 (kill).

Replaces the R1 seed .scm emitter with a bespoke Rust walker
(codegraph-kernel/src/tsjs/) that mirrors TreeSitterExtractor's TS/JS
paths function-for-function: declarations (incl. #808 field/property
classification), qualified names, docstrings (#780 wrapper climbs),
signatures, imports/re-exports + per-binding refs, calls with
receiver-qualified callees (#1230 literal-receiver skip), instantiations,
decorators, inheritance, type annotations (#381), type-alias members +
tuple contracts (#359/#634), React component recognition (#841
forwardRef/memo/styled), object-of-functions / zustand-through-middleware
/ RTK Query endpoints + generated hooks / vuex + pinia store shapes,
function-as-value capture with the flush gate (#756), and value-reference
edges with the shadow prune (#895/#897). The generic query emitter is
deleted — extraction parity needs logic .scm can't express; future
languages get walkers too (migration plan §4a).
Positions and JS string-slice semantics are emitted in UTF-16 code units
natively, so kernel output is byte-identical to web-tree-sitter's — no
column diff class exists.
Parity evidence (macOS): scripts/kernel-parity.mjs (full-object multiset
diff per file) — this repo 353/353 files, excalidraw 643/643 (10,650
nodes / 10,726 edges / 68,307 refs), plus torture fixtures checked into
__tests__/fixtures/kernel-parity/ and enforced in npm test by
kernel-tsjs-parity.test.ts. The strict compare caught one real decoder
bug the loose harness missed: refs must NOT carry denormalized
filePath/language at the extractFromSource seam (the store fills them).
Perf: extraction 2.6× single-thread on excalidraw (487ms vs 1,255ms,
identical outputs). Routing stays opt-in (CODEGRAPH_KERNEL_LANGS) until
the R3 equivalence gate (large repo, DB dump-diff, retrieval invariants,
agent A/B, Linux/Windows) passes.

Phase 0 of the Rust extraction-kernel migration (docs/design/
rust-kernel-migration-plan.md, now checked in with §3a recording the
shipped state):
- codegraph-kernel/ napi-rs crate: extractFile(path, content, language)
→ five flat buffers (meta/nodes/edges/refs/arena), one JS boundary
crossing per file. Node ids computed Rust-side, byte-identical to
generateNodeId (pinned by test vector). Reserved per-node metrics slot
for the Arc 3.2 code-metrics work.
- Generic .scm-driven emitter (@def.<kind>/@name/@ref.<kind> captures,
byte-range scope stack → ::-joined qualified names, contains edges,
refs attributed to the innermost enclosing symbol). Seed TS/JS queries
are smoke-level; R2 replaces them with the full port.
- Routing seam in extractFromSource with per-file wasm fallback.
DEFAULT_ROUTED is empty — no behavior change until a language passes
its equivalence gate (R3). Dev opt-in: CODEGRAPH_KERNEL_LANGS. Kill
switch: CODEGRAPH_KERNEL=0. Loader verifies ABI + kind tables before
routing; EDGE_KINDS became a runtime array because kind order is now
wire contract.
- Grammar-source parity: vendored TS/TSX/JS wasm grammars built from the
exact crate revisions (tree-sitter-typescript v0.23.2,
tree-sitter-javascript v0.25.0, checked-in parser.c, ts-cli 0.25.10) —
the tree-sitter-wasms builds were 2023-era, which the new
kernel-grammar-parity test caught on day one. Production TS/JS parsing
gets 2.5 years of grammar fixes; full suite green (2456 tests).
- Build/release wiring: scripts/build-kernel.sh + npm run build:kernel;
release.yml kernel prebuild matrix (continue-on-error — the kernel is
optional everywhere, bundles fall back to the wasm path); bundles stage
lib/kernel/codegraph-kernel.node; release job runs the kernel suites
with CODEGRAPH_KERNEL_EXPECT=1.
