Colby MchenryandClaude Opus 5.5 1b56cb1992 fix(explore): find COBOL copybooks by name, with every include site (#2342) (#2358)
`codegraph explore MYCOPYBOOK`, the `codegraph_explore` MCP tool and
`codegraph context` answered "No relevant code found" for a COBOL copybook
named in the query, while `query`/`node` found its include at once.

Cause: the COBOL extractor records `COPY X` and `EXEC SQL INCLUDE X` as
`import` nodes, and findRelevantContext filters every channel by
HIGH_VALUE_NODE_KINDS, which leaves imports out on purpose (a JS/TS/Python
import statement is noise in explore). With the include out of reach the
text search fell through to its fuzzy fallback, so a member with a digit in
it (never extracted as a symbol) came back as an unrelated program one edit
away: CVACT01Y -> CBACT01C, CVCUS01Y -> CBCUS01C on CardDemo. Making COBOL
imports "high value" alone would not have helped either: explore's renderer
skips import nodes, and the import-to-definition step drops a COBOL include
because its `imports` edge leaves the enclosing scope, not the import node.

Change:
- src/graph/cobol-copybooks.ts (new, shared derivation): resolves the COBOL
  words of a query to copybooks - every COPY / EXEC SQL INCLUDE of the member
  (case-insensitive) and the indexed copybook file (.cpy, or a file an
  include resolved to; a same-named program is not one). Gated on the
  project having COBOL files at all (one seek on idx_files_language), so no
  other language's query does extra work or changes. Plain lowercase words
  in a multi-word query are English, not member names.
- findRelevantContext: a named copybook's top-level declarations, then its
  include statements, become entry points ahead of the kind-filtered
  channels, like an exact filename (at most half the slots when the query
  matched other things, include sites in those files first). They are not
  walked (BFS from a record layout spent the answer on whichever program
  MOVEs into it), the member is not re-searched as text (the fuzzy decoy),
  and an explicit nodeKinds filter without `import` is honored.
- codegraph_explore: the copybook file is pinned like a path in the query;
  an include statement that is an entry point is grouped and rendered (a
  window around the COPY line) instead of skipped; a new "COBOL copybook"
  section lists every include site (path:line, COPY vs EXEC SQL INCLUDE,
  25 lines then a count) or says the member has no indexed source (DB2
  DCLGEN, compiler-supplied such as SQLCA/DFHAID).
- QueryBuilder: three indexed lookups; CodeGraph.findNamedCopybooks exposes
  the derivation so explore and the context builder share one answer.
No extraction change; no re-index needed.

Verification: __tests__/explore-cobol-copybook.test.ts (8 tests, through
ToolHandler codegraph_explore and buildContext): with src/ reverted to
origin/main 6 fail (the 2 guard cases pass on both), 8/8 pass with the fix.
tsc clean, npm run build OK. Issue repro fixed on the built CLI (explore +
context) and through a real `serve --mcp` tools/call. Full suite on a heavily
loaded box: 5716 passed, 25 failed in 15 files; 12 of those files pass alone,
and the other 3 (function-ref, git-index-currency, worktree-detection) are
5 s / 60 s timeouts that fail on clean main as well in interleaved runs.

Validation (both builds on one index per repo; query-side change only):
- expressjs/express: 14 explore + 4 context queries byte-identical.
- aws-mainframe-modernization-carddemo: 10 non-copybook queries
  byte-identical; 15 copybook queries all now return the copybook (when
  indexed) and every include site - before: 9 "No relevant code found",
  4 unrelated programs, 2 without the copybook.
- cicsdev/cics-genapp: 6 non-copybook queries byte-identical; 6 copybook
  queries fixed (LGCMAREA's 25 sites incl. multi-line EXEC SQL INCLUDE,
  lowercase lgpolicy, SSMAP with no indexed source).
- In-process explore latency on express unchanged within noise.

Thanks @popolusiak for the report.

Colby MchenryandClaude Opus 5.5 dea076fd1e fix(mcp,extraction): exit a daemon whose install changed; never store a grammar-load failure (#2335, #2336) (#2346)
* fix(mcp,extraction): a daemon whose install changed exits; grammar-load failures are never stored (#2335, #2336)

A daemon that outlived an upgrade loaded grammars lazily from an install
that no longer existed, and stored every file its watcher re-indexed as a
zero-node row under the file's new content hash: no hash-based sync ever
revisited those rows, and `codegraph status` called the index up to date.

- The daemon checks its own package.json every 30 s
  (CODEGRAPH_DAEMON_INSTALL_CHECK_MS, 0 turns it off) and exits once the
  file is gone or carries another version, so the next session starts a
  daemon from the current install.
- A result whose grammar failed to load (`parser_error`) is never stored:
  the file keeps its previous data and the next sync or index retries it,
  and a row an older engine stored that way is re-indexed even though its
  hash matches. The tag-based CFML path reports a missing grammar with the
  same code.
- A launcher whose own install was deleted no longer crashes on the spawn
  error of the daemon it tried to start.
- `codegraph status` and `status --json` (filesNeedingReindex,
  filesWithParseErrors) report indexed files whose symbols are missing
  although their content is current (#2336), and `files --json` carries
  each file's recorded errors.

* fix(mcp): a session whose own install changed never claims the writer lock (#2335)

A daemon now exits once its install is upgraded or removed, and nobody
holds the writer slot for a successor at that point. Its sessions run the
same replaced code and serve themselves in-process the moment it goes; one
that found the slot free claimed it as its writer even though its engine
could not load (a real npm upgrade: "Cannot find module
'./sqlite-adapter'"), and so kept a daemon from the current install from
starting. Such a session now falls back read-only and says to restart it.

Also adds the CHANGELOG entries for the install check and grammar-load
failures (#2335) and for the status report (#2336).

Colby MchenryandClaude Opus 5.5 e28ac71048 fix(sync): same-named symbols keep their own cross-file callers across a re-index (#2276) (#2288)
* fix(sync): same-named symbols keep their own cross-file callers across a re-index (#2276)

Re-storing a file re-attaches the edges other files had into it by moving
each edge to the re-indexed node that replaces its target. That pairing
keyed new nodes by (kind, name) with the last one winning, so in a file
defining a name twice — the same method on two classes, a method's
overloads — any edit, even a body-only one, moved every incoming caller
of those symbols onto one of them. A body-only edit leaves the sync's
definition delta empty, so nothing re-resolved them afterwards.

The re-store now reads the file's old node identities alongside the edge
snapshot and pairs old nodes with new ones by (kind, name), then
qualified name, then signature, then position within a same-sized group
of otherwise identical nodes. A target no tier can pair one-to-one is
resurrected as its original unresolved reference, so resolution rebinds
it instead of the store guessing.

The common in-memory re-store path also now deletes the old rows, stores
the new ones and re-attaches incoming edges in one transaction. Committed
separately, a failure between the steps left the file looking new or
already current, and other files' edges into it were lost until a full
re-index.

Colby MchenryandClaude Opus 5.5 455175da67 fix(mcp): a projectPath in a nested repo the ancestor index leaves out isn't answered from it (#2110) (#2287)
* fix(mcp): a projectPath in a nested repo the ancestor index leaves out isn't answered from it (#2110)

An explicit projectPath resolves to the nearest .codegraph/ walking up,
and that walk crosses git boundaries. Inside an independent repository
nested under an indexed parent that excludes it (typically gitignored),
every call silently answered from the parent's code.

After resolving the index root, ToolHandler now asks whether the path
sits in a different git repository strictly below that root (git
toplevel + common dir, memoized per path and root) and, if so, whether
the index holds any file under it (one primary-key range probe per
call). None means the success-shaped "isn't indexed" guidance. Nested
repos the parent does index (submodules, gitlinks, embedded clones),
ordinary subdirectories, linked worktrees of the same repository (the
when git can't run, behavior is unchanged.

Colby MchenryandClaude Opus 5.5 e12f5bbb92 fix(nuxt, astro): a file-routed page is bound to its component (#2267)
A Nuxt pages/x.vue or Astro src/pages/x.astro route linked to nothing, so
the viewer's Steps drew a page alone and the routes list never named what
serves it. Each page route now references its file's own component (never a
same-named one — every index.vue is a component named index), an Astro
endpoint its exported verb handlers, and the routing manifest accepts a
component as what serves a route, which also lists Vue Router screens.

Colby MchenryandClaude Opus 5.5 0419a51636 fix(synthesis): link a Spring or Laravel test's request to the route it reaches (#2100)
Tests reach a controller by URL, never by a call — MockMvc's
`perform(post("/owners/new"))`, Laravel's `$this->postJson('api/me')` — so
every controller those suites exercise read as untested: the viewer's
"No test reaches this" and explore's `tests:` line both walk callers.
petclinic's processCreationForm, hit three times by OwnerControllerTests,
said no test reached it.

A new synthesis pass (tier-synthesizer section 4, registered after the
cross-tier pass, gated on java / kotlin / php) reads test files only:
- Spring: MockMvc builders (with MockMvcRequestBuilders imported),
  `request(HttpMethod.X, …)`, the Kotlin `mockMvc.get(…)` DSL,
  WebTestClient `.get().uri(…)`, TestRestTemplate, RestAssured.
- Laravel: `$this->get/post/…Json(…)`, `->json('POST', …)`, `->call(…)`
  on a chain rooted at `$this` that only calls methods (so
  `$this->app->get('config')` is not a request); Pest's helpers where the
  file imports Pest\Laravel; and a project's own verb-named helpers
  (koel's getAs → jsonAs → `$this->json($method, $uri)`), recognised by
  their body, never by name alone.
Paths are read as built — Spring `{var}` templates, PHP / Kotlin
interpolation and concatenation become holes — and matched with the
cross-tier pass's own route matcher (a hole fills a parameter, never a
literal). One `calls` edge per (test, route), `synthesizedBy:
'test-request'`. These edges are excluded from countIncomingEdges, so a
well-tested endpoint never becomes a hub the Steps walk refuses to enter.

Routes reached by a test: petclinic 16/17, realworld 18/19, BookStack
194/340, koel 105/134 (from 0 each). A random sample of edges checked
against the test source was all correct. The pass costs 86 ms on
BookStack and 68 ms on koel.

09b9646b7e perf(context): compute the dominant file once per index state (#1864) (#2086)
* perf(context): compute the dominant file once per index state (#1864)

getDominantFile() backs context ranking's core-directory boost. Its answer
depends only on the graph, but the whole-graph aggregation behind it
(edges joined to both endpoints' nodes, grouped by file) ran on every
generic codegraph_explore - seconds per call on a large index.

Memoize it in QueryBuilder against a database change stamp:
total_changes() (rows this connection wrote) plus PRAGMA data_version
(commits by any other connection or process). Both are O(1), so no write
path has to remember to invalidate, and a sync made by another process is
seen on the next call. Any write forces a recompute; the heuristic's
result is unchanged.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(context): never keep a dominant file read inside a transaction (#1864)

total_changes() counts writes that are later rolled back, so a result
computed inside a transaction could survive the ROLLBACK under an unchanged
stamp and describe edges that no longer exist. getDominantFile now skips the
memo while a transaction is open (and on a runtime without isTransaction).
Ported from the maintainer's hardening of this fix in #1919.

* fix(db): drop the dominant-file memo when a QueryBuilder is rebound (#1864)

The memo's change stamp (total_changes + data_version) is per connection,
and fresh read-only connections to two different databases report the same
one ("0:2"). A pool worker rebound onto a rebuilt index kept serving the old
database's dominant file until something wrote through the new connection.
A test rebinds onto a second project and fails without the reset.

Colby MchenryandClaude Opus 5.5 fef37765c1 perf(resolution): remove the indexing regressions since v1.6.0 (vscode stall, per-ref rescans) — graph byte-identical (#2072)
* perf(resolution): read JS/TS parameter lists without exponential backtracking

isLocallyBoundJsName (#1759, cd4e65b5) scans a file for a parameter that
binds a bare-called name. Its per-parameter pattern `(type)?(default)?\s*`
let one `name: T = value` text split several ways, so when the name was
absent the search backtracked through every combination. On vscode's
markersModel.test.ts, whose helper takes nine typed, defaulted parameters,
each `suite`/`test` scan took 30-40s — one pool worker held a whole
resolution batch while the rest idled, a 70-400s stall per run.

Each parameter now has exactly one parse: its first non-space character
after the identifier picks the type, default or bare alternative. The
alternatives match exactly the strings the old optional groups did, so the
result is identical for every input (4M generated cases and 5.6k real
vscode file/name pairs agree); the scan is 0.1-0.3ms on that file.

* perf(resolution): memoize Python module-file lookups per resolution pass

#2034 (5eaa6fed) sent every Python named import whose path the import
resolver cannot place — stdlib and third-party modules such as
`from unittest import mock` — through findPythonModuleFile, which scans
every `__init__.py` file node for a path suffix. It ran once per ref:
on django that scan alone went from 0.6s to 1.4s of resolution CPU.

The candidates for a module depend only on the module path, so they are
now collected once per resolution context, in the same name-lookup order;
the importing file is still excluded per call, so the first survivor is
the node the scan returned. The memo drops with the other import-resolver
memos. Resolution output on django is hash-identical; single-threaded
resolution CPU there goes from 6.5-6.8s to 4.9s (v1.6.0: 4.5s).

* perf(resolution): test sealed-module candidates cheapest-first

isSealedModule (#1719, bffd50e4) masks a candidate file's comments and
strings before asking whether it is a module that exports nothing. Import
refs call it for every same-named candidate across the tree, so on vscode
it masked nearly every TypeScript file once per resolver: 3.3s of masking
in a single-threaded pass, paid again in each pool worker.

The verdict is a pure conjunction, so it now asks the cheap questions
first: the source contains `import`, no node in the file is exported, and
there is no CommonJS export. Masking runs only for files that pass all
three, which in practice are the few that can be sealed. The masker blanks
text and never deletes it, so a file without `import` in its source has
none in its masked code either. Resolution output is hash-identical on
vscode and django.

* perf(resolution): scan a class for a field's declared type once per field

matchTsThisFieldCall (#1496, cece0720) resolves `this.<field>.<method>()`
by finding the field's declaration in the enclosing class. It re-split the
whole file, stripped comments line by line and compiled three patterns for
every such call, although the answer depends only on the class and the
field: 16.5s of a 148s single-threaded resolution pass on vscode.

The first declaring line — `: typeof X`, `: X` or `= new X`, in that order
per line — is now memoized per (class node, field), and the last few
classes' stripped lines are kept, since calls arrive file by file. Owners
are still tried in the same order and everything after the declaration
lookup is unchanged. Resolution output is hash-identical on vscode and
django.

* perf(synthesis): start cross-tier receiver chains only at a word's start

The cross-tier pass (b1f40c57) scans every non-test JS/TS file whose text
has a `.add(`, `.get(` or `.on(` — nearly all of vscode — with receiver-
chain patterns such as `a.b.c.add('job')`. A chain could begin at any
letter of an identifier, so each letter re-read the dotted chain behind
it; on vscode the pass ran 35s on one pool worker and set the synthesis
phase's wall.

A match that starts mid-word implies one from the word's first letter, and
every match of these patterns ends on a non-word character, so a scan
never resumes mid-word: a lookbehind that rejects those starts skips only
attempts bound to fail. Over all 14,135 vscode JS/TS files the five
patterns return identical matches (positions and groups) before and
after, in 8.8s instead of 32.8s; the pass itself drops from ~9.8s to
~5.6s CPU standalone.

* perf(resolution): filter same-named candidates in one pass, cheap checks first

Interface members (#1638) and nested const-bound functions (#1669) made
common names — `editor`, `model`, `dispose` — carry thousands of nodes.
matchByExactName ran ten chained filters over that list for every
reference, copying it once per rule before the source-reading checks ran,
and the method-call strategies copied it again to put the call site's file
first before looking at only the class-like or same-file entries.

Each rule judges one candidate on its own, so the exact-name rules now run
as a single pass with the kind and language checks ahead of the lexical,
sealed-module and local-binding checks; the class strategies narrow to
owner kinds before ordering by file (the same nodes in the same order),
and the object-literal strategy, which keeps same-file holders only,
skips the reordering altogether. Resolution output is hash-identical on
vscode and django.

* perf(synthesis): scope language-specific node scans in SQL

Eleven synthesis passes stream every node of a kind and keep only their
language's (Go, Java/Kotlin, XML, native, ArkTS, Nix, Erlang). On a
TypeScript monorepo the Go passes materialized all 113k vscode methods to
find two Go ones — goMethodContains alone went from 0.5s to ~2.9s on the
main thread after interface members (#1638) grew the method count and the
canonical ORDER BY (#1988) landed.

iterateNodesByKindIn adds the language predicate to the same query. Its
ORDER BY (file_path, start_line, id) is a total order, so it yields
exactly the nodes the callers kept, in the same sequence.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* perf(synthesis): run the synthesis-site index and source-gate scan beside the passes

Two serial main-thread steps landed with the incremental synthesis refresh
(#1988, #2038). The bulk-edge window rebuilt idx_edges_synthesis_site
before synthesis — its partial predicate runs json_valid over the
metadata of every edge (~1.5M rows, 2.7s on vscode) — and after the merged
insert synthesis re-read every file in the project to record its source
gates (~1.9s). Neither result is read until the index is finished: only
sync consults the index, and the gates depend only on the files.

The window's end now leaves that one index for later, and the resolver
builds it while the pool computes the passes, when the main thread was
only waiting; the source-gate scan runs in the same window. Both still
happen before resolution returns, whatever path synthesis takes, and a
crash in between is healed on the next open as before. On vscode
edge-index-recreate drops from 8.3s to 3.6s of serial time; the graph,
synthesis_inputs and the final index set are identical.

* perf(resolution): stop re-reading resolved targets and re-probing missing files

Every resolved reference now re-reads its target node several times —
the kind gate (#1796), the cross-family language gate (#1986), alias
following (#1482) and edge creation — through the query layer's
1,000-entry node cache, while targets recur ~5x (1.46M vscode edges onto
293k nodes). The language gate alone spent ~6s of single-threaded
resolution on vscode fetching whole nodes to read one field, and
fileExists re-probed the same missing candidate paths (every extension of
a `.js` specifier) from every importing file, now under a path.resolve
containment check (#1631).

The resolver keeps its own id → node cache and a memo of filesystem
probes, both in the stable window of its other caches and dropped by
clearCaches; the language gate returns early when the reference's
language has no code family (no target can cross one) and otherwise
memoizes each target's language. Resolution output is hash-identical on
vscode and django.

* perf(resolution): cheaper sealed-module and receiver-less call checks

isSealedModule read and decoded a candidate file — its source and every
node — to learn whether anything is exported, though nearly every module
does. It now asks one indexed EXISTS probe first and reads the source only
for files that export nothing (the conjunction is unchanged).

isReceiverLessCall (#1759, #1857) compiled a pattern per call and
end-anchored two more over the line's prefix, which V8 scans from the
start. It now matches the name literally with a sticky `\s*[(<]`, and reads
the prefix backwards: the last non-space character decides whether a
receiver precedes the call, and the word run ending there decides the
keyword exception — exactly what `[.\w$\])]\s*$` and
`\b(?:return|...)\s*$` accepted. Resolution output is hash-identical on
vscode and django.

* perf(synthesis): pull passes onto workers heaviest-first; cheaper registry and tier scans

The pooled fan-out handed every pass out at once, so each worker held a
count-based share and a heavy pass finished only with its worker's whole
share (vscode's registry pass ended ~16s in). Workers now pull one pass at
a time, heaviest first; edges still merge by registry index, so the output
is unchanged. vscode synthesis: 14.5s vs 19.6-24.4s.

The registry pass retried its greedy name at every character of every
identifier; both scans now start a name only at an identifier's first
character or a `this.` (a mid-identifier resume after a `.method` dispatch
falls back to the unguarded pattern), and dispatch lines come from a
newline-offset lookup instead of splitting the prefix per match. Checked
match-for-match against the old patterns on every vscode JS/TS file plus
300k fuzzed strings. The tier pass reads a file's nodes only when a site
needs them. Standalone on vscode: registry 5.6s -> 4.5s, tier 5.1s -> 4.4s.

* perf(resolution): lean export indexes; no per-name regex compiles in field and local-binding checks

Three per-lookup costs the resolver pool paid once per worker:

- A file's export index decoded every node in the file and read its source,
  for each file an import reached, in every worker. It now reads only the
  exported rows (same `start_line, id` order); the default-export binding
  and names a local `export { a as b }` clause introduces are read on first
  use, from name-targeted rows. findExportedSymbol across vscode's workers:
  12.5s -> 3.7s.
- The `this.<field>` declaration scan compiled three patterns per field of
  every class and walked every class line. Each pattern needs the field as
  a whole `[\w$#]` token, so a class's lines are indexed by token once and
  three sticky patterns, compiled once, are tried at the field's token
  occurrences. Identical on 721k vscode (file, field) pairs; 56.7s -> 1.1s
  standalone.
- isLocallyBoundJsName searched the whole file with four patterns per name.
  Each can only start at a `const`/`let`/`var` or `function`/`class`
  keyword, an `=>`, or the `(` opening a list before the name, so the
  patterns (compiled once per name, sticky) are tried there. Identical on
  198k vscode (file, name) pairs; 68.1s -> 10.7s standalone.

Replaying every vscode (2.19M) and django (270k) reference single-threaded
gives the same result hash before and after.

* perf(resolution): prepare kind-filtered edge reads once; memoize the inherited this-member walk

- getOutgoingEdges / getIncomingEdges with a kind filter prepared a fresh
  statement on every call, a third of the read's cost; they are issued per
  node by supertype walks and the member-lookup synthesis passes. Each SQL
  shape is now prepared once per connection (dropped on rebind).
- The post-loop `this.<member>` pass walked the same supertypes for every
  reference, reading each one's contains edges and decoding members one by
  one until a name matched. Nothing is written until the pass ends, so each
  type's supertype edges and each supertype's callable members (by name, in
  edge order) are read once. vscode: 4.1s -> 1.0s.
- Express's mount pass decoded every JS/TS file to look for `.use(`; it now
  checks the raw bytes first (an ASCII needle survives UTF-8 decoding
  unchanged) and decodes only files that have it.

A full vscode init dumps the identical graph before and after.

* perf(resolution): fan the next batch out before inserting edges resolution never reads

The batch loop inserted every batch's edges before fanning out the next
one, so the pool sat idle through each insert. That ordering exists for
one reason: later batches walk supertype chains over the `extends` /
`implements` edges earlier batches resolved. Those are the only edges
resolution reads, and the prerequisite phase drains every such ref first,
so after it no batch makes one. A batch without them now fans the next
batch out first and inserts while it resolves: the same writes in the same
order, and nothing the workers read differs. The kinds live in one
constant, shared with the supertype walk.

vscode resolution, three interleaved rounds against the parent commit:
50.3-51.0s vs 56.8-59.1s wall (the pool's wait per batch halves; the
overlapped inserts cost ~7s more CPU). Full vscode and django inits dump
identical graphs before and after, and identical to main.

* perf(db): prepare the edge-endpoint existence check once

Every edge insert checks its endpoints with a 500-id IN query, a chunk at
a time, and prepared that statement afresh for each chunk. The batch loop
now runs these inserts on the main thread while the pool resolves, so the
full-size statement is prepared once; only a final partial chunk prepares
ad hoc (as deleteReferencesByRowIds already does). Same SQL, same result.

Colby MchenryandClaude Opus 5.5 c13bd0890f fix(wsl): keep WSL off Windows' index on /mnt drives, and explain the I/O error (#995) (#2061)
When Windows-native and WSL CodeGraph both open the same
.codegraph/codegraph.db under /mnt/<drive>/, SQLite's locking and -shm
shared memory don't hold across the 9p/DrvFs bridge and WSL fails with a
bare "disk I/O error".

- A SQLite I/O error on the default index of a WSL /mnt/<drive> project is
  rewritten (in the SQLite adapter, so every open and query is covered) into
  the CODEGRAPH_DIR=.codegraph-wsl instruction. MCP answers it success-shaped,
  and a failed default-project open is reported instead of "no project loaded".
- On WSL + /mnt/<drive> with CODEGRAPH_DIR unset, the data dir is resolved per
  root: an existing .codegraph-wsl/ wins, then an existing .codegraph/ index
  (kept, no silent re-index), else a fresh index goes in .codegraph-wsl/.
  `codegraph init` says where it went. Every other host is unchanged.

* fix(mcp): close pending sockets and allow read-only fallback (#1963)

* fix(mcp): log when a fallback serves reads without auto-sync (#1963)

A read-only fallback starts no watcher and holds no writer lock, so a

the logs. Name the holder on stderr when the fallback goes read-only.
Suggested by @bompus in #1979.

Colby MchenryandClaude Opus 5.5 71985f2620 fix(db): guard synthesis metadata JSON and keep calls ahead of imports (#2038)
* fix(db): guard synthesis metadata and migrate the expression index

Bisect identifies 2a2f71ec (#2033) as the malformed JSON regression. Guard index expressions, ownership predicates, wiring lookups, and the legacy Go backfill; schema v11 replaces existing v10 indexes. Cover malformed base edges, staged publication, upgrade replay, and indexed range lookup.

* fix(db): preserve call precedence in deterministic edge traversal

Independent bisect identifies 2a2f71ec (#2033): source-first ordering puts importing file IDs ahead of function callers and consumes the default caller limit. Restore kind-first incoming and outgoing traversal with deterministic endpoint/position ties. Keep both original regression tests unchanged and cover filtered, cached, and provenance-filtered queries across reverse insertion order.

Validation: 25 test files passed (564 tests, 3 skipped), including security, MCP caller truncation, sync, migration, graph, and DB/query coverage; npx tsc --noEmit passed. Both bisects rebuilt tsc and copied assets at every step with CODEGRAPH_KERNEL=0 to avoid using the HEAD kernel on historical extraction code. Final validation used the normal kernel setting.

* chore: no changelog entry for an unreleased regression

e5fb5e390e fix(mcp): deduplicate equivalent project paths (#1057) (#2020)
* fix(mcp): share one connection across two spellings of one root (#1057)

A symlinked checkout, or a case-variant of a root on a case-insensitive
mount (macOS, NTFS, WSL DrvFs), resolved to two path strings and opened two
connections to the same .codegraph/codegraph.db.

The connection cache stays keyed by path, so a root recreated at the same
path still heals in place (#925). On a miss, an open root that is the same
index NOW (both data directories stat to one dev:ino, read as bigints) is
reused and the new spelling filed as its alias. Comparing live identities
means a deleted root never matches, even if a new directory reuses its
inode. Windows has no usable inode, so it compares the case-folded
realpath.native instead. statInode moves to directory.ts so the DB layer
and the cache share one reading, and closeAll closes an aliased instance
once.

* fix(mcp): keep root aliases out of the connection cache (#1057)

A second spelling of an open root was filed in projectCache under its own key,
so one CodeGraph sat under two keys. Anything that drops one key and closes its
connection (a bounded cache's eviction, as proposed in #1929) then left the
other key holding a closed handle: every query on that spelling, and through
the alias scan on the original spelling too, failed with "database is not
open" until restart.

Aliases now live in their own map (spelling -> projectCache key). projectCache
is back to one key per instance, and an alias whose entry is gone is dropped
and re-resolved instead of served.

* fix(mcp): deduplicate equivalent project paths (#1057)

Equivalent project paths could open duplicate cached connections.
Compare current filesystem identities using bigint inodes and native Windows paths.
Revalidate aliases and pin cached connection owners to symlink targets.
Preserve recreation recovery and single-owner cleanup.

52b854d44a fix(dead-code): propagate external ancestor uncertainty to descendants (#1973) (#2007)
* fix(dead-code): treat an ancestor outside the index as opaque (#1973)

An override is excluded from the dead-code report when its ancestor is in
the graph, or is present but declares no members we can read. An ancestor
outside the project (React.Component, stream.Transform, a NestJS
interface) creates no edge at all, so a lifecycle method the framework
calls looked like it overrode nothing and was listed as unreferenced.
The resolver does record such an ancestor, as a failed extends /
implements row. A container with one, or a project ancestor of one that
has it, now counts as having an opaque ancestor, and its members are
excluded under "overriding".

* fix(db): graceful FTS5 fallback when Node.js build lacks FTS5 support (#1532)

Official Node.js binaries do not compile FTS5 by default, causing codegraph
init to fail with 'no such module: fts5'. Added runtime FTS5 detection:
- Split schema execution to try FTS5 separately, skip on failure with warning
- Added fts5Available flag to DatabaseConnection and QueryBuilder
- Bulk-load and search paths skip FTS5 operations when unavailable
- Search falls back to LIKE + fuzzy matching when FTS5 is missing

(cherry picked from commit ed708b7f60)

* fix(db): preserve core schema during FTS5 fallback (#1532)

Keep required tables and indexes after the FTS triggers outside the
optional schema block in the upstream #1625 fix. Without this boundary,
simulated-missing-FTS5 indexing still fails on name_segment_vocab.

Add seven regressions using real SQLite with FTS5 creation intercepted,
covering initialization/open, LIKE and fuzzy search, non-FTS schema parity,
bulk no-ops, and real FTS5 search and bulk-load recovery. Credit
@aniruddhaadak80 under Unreleased fixes.

Validation on Linux x64 with Node v22.19.0:
- npm run build passed, including viewer and grammar asset checks.
- 34 tests passed across fts5-fallback, node-sqlite-backend,
  sqlite-backend, and db-perf.
- Rebuilt CodeGraph initialization, indexing, reopening, search, and
  cross-file callers passed with simulated missing FTS5 and real FTS5.

Fixes #1532.
Supersedes #1625.

9181dd1ef3 fix(extraction): land upstream declaration initializer walks (#1511) (#1802)
Squash danusha2345's PR #1511 at d282f9e8 onto main 8c9c4761,
preserving its nine non-merge commits and main's existing Unreleased notes.
Calls in Kotlin, Java, TS/JS, Scala, Rust and Python declaration initializers
now retain the owner established by the upstream regression expectations.
Include the upstream CFML, dynamic-dispatch summary and viewer follow-ups.

Linux fail-to-pass validation (Node 22.19.0, rebuilt dist and native kernel):
- Before: TS load belonged to file:app.ts; Python/Kotlin/Scala/Rust calls
  vanished; Java lost the field-lambda, anonymous override and eager calls.
- After: all six languages PASS; 12 native/WASM LF/CRLF parity checks PASS.
- Focused initializer regressions: 10 passed with CODEGRAPH_KERNEL=0 and
  10 passed with the kernel enabled; Kotlin's grammar fallback is recorded.
- Related regression suites: 879 passed, 1 skipped across 15 test files.
- Evidence: /workspace/cg-1510-repro/before and /workspace/cg-1510-repro/after
  (combined test output: after/vitest.log).

Fixes #1510
Supersedes #1511

Colby McHenryandClaude Fable 5 b1f40c57dd feat(steps): cross-tier channels — a client's fetch onto its own route, queue jobs onto consumers, bus and socket events onto handlers
- resolution/tier-synthesizer.ts: http-client (literal fetch/axios/ky/got/$fetch paths, axios.create baseURL instances, template holes as :params, base-URL holes by a two-segment tail; unique match only), queue-job (BullMQ/Bull add ↔ @Process/@Processor, WorkerHost process, new Worker, queue.process), event-bus (EventEmitter2 emit ↔ @OnEvent with globs; socket emit ↔ @SubscribeMessage / socket.on both ways with tier); channel, tier, callee, registeredAt on every edge; generic transport events never pair; test and generated files never sources; registered before the emitter pass
- steps.ts: crossing() reads tier/channel before languages; an endpoint reached across a tier is a bridge box and a boundary like a screen (through=1 enters it); a channel's call is not also an effect; sites read as written; a Next 'use server' action is a crossing by its directive (when.ts directive); a function-valued constant handler (asyncHandler(...)) is a route root and borrows the file-scope calls and refs within its lines
- express.ts: app.use('/prefix', router) mounts composed onto route names in postExtract (nested, by import or require); chained router.route('/x').get(h).put(h2) extracted, across lines
- frameworks/package-deps.ts: dependencies read from workspace package.json files too (Express, React, Expo Router, NestJS detect)
- routing manifest names constant handlers; e2e/ is a test directory; explore's Flow section labels the new channels
- tests: ui-steps-cross-tier (monorepo fixture: Next client + Express/Nest API), servers test updated for the queue landing

Colby McHenryandClaude Opus 5 56dfdb0655 feat(ui): dead code and islands — what nothing reaches, and everything that could still reach it (CG-59)
A Dead code screen and a mark on the Map, both drawn from one derivation in
src/graph/dead-code.ts so a second surface can never disagree with the first.

The SQL half is four lines — no incoming edge but `contains`. It returns ~2 500
candidates on this repository and the shipped list is 20; everything in between
is the feature. A candidate is dropped the moment there is any reason to believe
something outside the graph reaches it: exported symbols and header
declarations, test and generated files, abstract and interface members, anything
carrying a `decorates` edge, overrides of an ancestor's member, names the
language calls by itself, vendored directories, files nothing in the index
reaches (those are islands, and the Map says so instead), names the resolver
failed to resolve somewhere, and names shared with a symbol that IS referenced —
the mis-resolution that leaves a used method with a self-edge and its twin with
nothing. The last rule is the only one that is not a graph query: before a claim
is made, the declaring file and every file that reaches it are read and the
identifier counted, which is what catches the references the extractor never
recorded (`this.handleMessage.bind(this)`, a call inside an object literal, a
shorthand property).

Every subtraction is counted and printed under the list with the scale it came
from, and the caveat line above it never collapses: the claim is "no static
reference in the index", not "unused".

On the Map a module nothing depends on keeps its stroke and says so in its count
line, and tool-generated files and modules recede to ink-4 there, in the map's
file list, in search results and on the file screen.

Colby McHenryandClaude Opus 5 94f4e287e6 feat(ui): entry points — routes, executable files and tests as flow starting points (CG-54)
`#/entry` answers "where does anything start" at full length, and turns any row
that names a symbol into a flow.

Server. `/api/entrypoints` gains `frameworks` (from `getDetectedFrameworks`), a
`tests` list, a `routes` limit of its own, and a cache keyed on the index build
— nothing here is read from disk, so unlike `/api/source` a cached answer cannot
be stale about drift. `routes.items` is now a `WireList` like every other list on
the payload.

Routes carry where the URL is REGISTERED as well as where it is served:
`getRoutingManifest` selects the route node's id, file and line, and
`buildRoutes` splits the verb off the name against a fixed list (never "the
first word", which would take the head off a file-routed `/blog/[slug]`). All
four payroll-go routes register in one router file and three are served from
another — group by the handler file and one router becomes two groups plus an
orphan.

`isTestFile` is split into `isTestPath` (test filename and directory
conventions) + the non-production catch-all, byte-identical at every existing
call site. The Tests list uses the narrow half: an example, a benchmark or a
fixture is off-target for ranking but is not a test, and a heading that says
"Tests" must not quietly count them. Tests rank by REACH — distinct other files
touched — because Go, Rust and Java put test work inside functions where a
module-level-calls ranking sees nothing. Two read-only engine queries make that
affordable: `getFileReachCounts` (the mirror of `getFileDependentCounts`, driven
from `nodes` by path so the cost follows the files asked about rather than the
edge table) and `getFileNodes`.

Viewer. `ui/src/lib/entry-model.ts` folds the four lists into file groups —
pure, and `panel.rows` stays exactly the sections it draws. `EntryView` +
`EntrySection` render them with the caller rail's `.filegroup` / `.row` shapes
rather than a second visual language for the same idea. A row that names a
callable symbol carries a `Flow ›` chip; the other end is typed or picked with
`→ here` on another row. File and test rows carry none: `/api/flow` searches by
name, and a file has none the path finder can look up.

A project with fewer than three resolvable routes gets no Routes heading at all,
not an empty one. Typing into the search box now also returns matching entry
points under their own heading below the symbol matches, so a URL comes back
with its handler attached; rows already in the results are dropped.

Colby McHenry ecd6e1cd15 feat(ui): live refresh and drift banners — the viewer keeps up with the project (CG-53)
`GET /api/events` is a server-sent-event stream the viewer holds open for the
life of the page. Two signals, two things the browser could not know:

  changed  source files touched on disk, before any sync — the drift banner
  index    the graph moved, naming what the sync re-indexed — the live refresh

The server WATCHES and never syncs: the project tree through the engine's own
FileWatcher with a notify-only syncFn, the index through one non-recursive
fs.watch on the data directory settled at 400 ms. Both start with the first
subscriber and stop with the last, so a viewer nobody has open costs no watch
descriptors. Nothing polls, on either side.

Drift is now parity with codegraph_node (#1474) rather than an absence.
`/api/source?ondrift=current` serves a drifted file's CURRENT bytes flagged
`showing: 'current'`, and the three screens that can say so switch off
everything anchored to the old line numbering — gutter ports, call-site links,
call arcs, the callee rail's anchoring — while keeping the source. The banner is
paper-2 with a hairline rule, never amber: amber belongs to the untested badge.

Also fixes a stale read this exposed. A long-lived reader holds an LRU of nodes
by id that only its own writes invalidate, so `/api/node/<id>` kept answering
with a symbol another process's sync had deleted while `/api/search` beside it
said it was gone. GraphSession now drops the read caches when the database (or
its WAL) has been written, and the Symbol view follows a symbol whose id changed
because an edit above it moved its start line, carrying the trail across.

Measured on a live viewer: banner 360 ms after a save, toast 440 ms after
`codegraph sync` returns, 0 requests in 4 idle seconds, and the client gives up
reconnecting after ~90 s with "Not live" rather than hammering a dead port.

Colby McHenryandClaude Opus 5 bd99c5e99a feat(ui): the whole file — full source with gutter ports and intra-file call arcs (CG-52)
The File view gains a Source tab: the file itself, top to bottom, with the
Symbol view's line grid, gutter ports and call-site links, a line-anchored
callee rail, and — in the left margin — an arc for every call that stays inside
the file, drawn from the calling line to the callee's definition line.

The arcs are the point. Source order is already a layout, chosen by whoever
wrote the file, so a file's internal call structure can be drawn with no
algorithm placing anything. Crabviz's idea, in the one place it is legible.

Everything is arithmetic, not measurement. The Symbol view queries the laid-out
DOM to place a callee row beside its line; a 6 820-line file cannot afford that.
Here a line is exactly 20px at `10 + (n - 1) x 20`, so ~90 line elements exist at
a time and the arcs, ports, rail rows and connectors are all functions of a line
number. `src/mcp/tools.ts` scrolls at a 16.6ms median frame.

- `GET /api/filecode/<path>` — outline, one call group per (caller, callee) PAIR
  with its call-site lines, unresolved references, and the file's length. The
  source is NOT in it: it pages through `/api/source` 800 lines at a time with a
  discarded 150-line lead-in, so a page starting inside a block comment does not
  render prose as code, and so the ports and arcs are complete from the first
  frame while the text fills in behind them.
- `intraFileCalls` is counted over the groups actually returned, so the header
  and the picture under it cannot disagree once a cap bites.
- Above 40 arcs the diagram narrows to the symbol under the pointer (or the one
  the scroll position is inside) and the header states the total. Accent is for
  the pointer only, never for the filter.
- Sticky outline rail at >= 1400px, following the reader down the file.
- `QueryBuilder.getUnresolvedReferencesInFile` — one indexed lookup instead of
  one per symbol; `buildOutlineEntries` lifted out of `/api/file` so both
  readings of a file draw the same rows.

Colby McHenryandClaude Opus 5 6d0f60f32c feat(ui): the Map — the repository at module granularity, layered from the graph (CG-49)
`GET /api/map` rolls the whole edge table up to module granularity in one
`GROUP BY`, and the Map tab draws it: one box per directory, dependencies
pointing down, nothing placed by hand.

Two decisions carry the screen.

The vertical order rests on each link's `declared` weight — the edges resolved
through an import, a qualified name, an inheritance clause or a typed receiver —
not on its raw count. Bare name matching resolves `run`, `push` and `finish`
across unrelated directories, and layering on raw counts put `src/db` directly
under `src/bin` on this repository's own index. On declared edges the same data
reproduces the pipeline CLAUDE.md describes, with a third of the mutual pairs.
When too few links carry a declared edge to describe a project, the layout falls
back to raw counts and the side panel says so.

And the aggregation is a single scan. Grouping by the symbol names as well as
the modules costs nothing extra — the join is what is expensive — so one query
yields both the link weights and the tooltip's symbol pairs. Measured against
this index inflated to 800k edges: 1.28s for one scan against 1.89s for two,
which is the difference between meeting and missing the cold budget on a
ten-thousand-file repository. Cached answers come back in ~3ms.

Nothing is dropped silently: thin links are hidden until a module they touch is
selected and counted in the panel, uncertain references are excluded from every
number on screen and the total is printed, and mutual dependencies, module loops
and file-level circular imports are listed rather than straightened away. An
edge that still points up after layering is drawn dashed on selection instead of
being reversed or removed.

The layout — cycle-breaking, longest-path layering, barycenter ordering, ports —
is a pure function of the payload in `ui/src/lib/map-model.ts`, so the tests
toggle and the selection cost no round-trip and the same project always draws
the same picture. Svelte Flow supplies pan, zoom and fit; never a layout.

Colby McHenryandClaude Opus 5 87afc50e76 feat(ui): the search palette, entry points and a trail that survives the URL (CG-45)
Search: `/` or ⌘K focuses the box; results arrive grouped by kind with their
glyph, signature and file:line, ↑/↓/Enter walk them, Esc dismisses. A group
appears where its best result did, so flattening the groups reproduces the
ranking the keyboard walks — the panel's flat item list IS that concatenation.
A flow question ("how does X reach Y", "X -> Y") is recognised and searches
both endpoints with a note, rather than offering a row that would land on the
phase-2 Flow view.

Entry points answer "where do I start" on the empty screen and in the resting
palette, all derived from the graph: routes, files that run something at module
level (the engine records a top-level statement as an edge out of the file node,
which is what makes src/bin/codegraph.ts the root of the CLI flow — ranked by
calls x the files they reach, so a registration table calling into itself does
not outrank the CLI), and the most depended-on symbols. Tests are excluded from
both derived lists.

Trail: hops record the direction they were walked (→ into a call, ← up to a
caller), clicking one truncates back to it, Clear keeps the place instead of
throwing it away, and the whole walk travels in the URL. A shared or reloaded
trail arrives as ids, so hops learn their names back through a new batch
endpoint and a session name cache — without it, walking back across a
truncation redrew earlier hops as raw hashes. "Read as flow" stays hidden until
there is a Flow view to send it to.

New endpoints: /api/entrypoints and /api/nodes. New engine reads:
getTopCallingFiles, getFileDependentCounts.

Colby McHenryandClaude Opus 5 5cecaabfc2 feat(ui): the Symbol view — callers, gutter-ported source, line-anchored callee rail (CG-44)
The core screen of `codegraph ui`: who calls a symbol on the left, its
verbatim body in the middle with a port on every line that has an outgoing
edge, and what it calls on the right — each callee row placed beside the line
that makes the call, with a hairline connector between them.

The callee rail is the part that is not a list. A row wants to sit at the
centre of its first call-site line and is pushed down only when that would
collide with the row above, so the rail keeps source order; the connector
still runs to the real line, so the displacement is visible rather than
silent. Positions come from measuring the laid-out DOM, so they are
recomputed on resize, on font load and whenever a fold opens.

Honesty is carried in the drawing, not in a footnote: a filled port means the
resolver matched something on that line and a hollow one means it only
guessed; uncertain connectors are dashed and their targets fold away behind
their count; synthesized edges are dashed differently and tagged with the
mechanism that made them; references that leave the index are text with a
soft underline rather than links to nowhere, and they are counted. Long
bodies keep their head plus a window round every call site — windowed on
graph edges only, since a function calling `console.log` two hundred times
would otherwise window round every line and buy nothing. Containers over 80
lines show a members outline with per-member fan-in/fan-out instead of 700
lines of braces.

Two small additions to the read-only API this needed:

* `/api/node` gives every outline member its own fanIn/fanOut (two batched
  queries for the whole outline). A class's own fan-out is nearly always
  zero because its methods do the calling, so without these the outline
  cannot say which member carries weight.
* `/api/stats` gains `blastScale` — the denominator the blast bar is drawn
  against, so one symbol's radius reads as wide or narrow *for this repo*.
  It is measured across the index's 24 most-depended-on symbols (found with
  a new `getTopDependedOn`, distinct dependents rather than edges), memoised
  against the index stamp, and reported as sampled; a symbol wider than the
  sample becomes the scale instead of overflowing the track.

Verified against a real index in a real browser: parity with the prototype on
`CodeGraph.sync` (259 lines, 27 callee rows, no overlaps), `GraphTraverser`
(20-member outline), a 773-line function (26 windows, 78 connectors), light
and dark, hover linking in both directions, keyboard-only navigation, and
reflow on resize and on fold toggles.

Colby McHenryandClaude Opus 5 951ba3678a feat(ui): read-only JSON API over the index for the viewer (CG-42)
Six endpoints under `/api/`, one per screen, each answering in a single
round-trip in the spirit of `codegraph_explore` — the viewer should never
have to ask a follow-up question to finish drawing a pane:

    /api/stats                     index state, graph counts, frameworks
    /api/search?q=                 ranked, kind-grouped symbol search
    /api/node/<id>                 rails, members, tests, blast radius
    /api/source?file=&from=&to=    verbatim source + a drift verdict
    /api/file/<path>               outline and import rails
    /api/routes                    URL -> handler, when there is one

It is a reader of the existing schema: no extraction or resolution changes.
It mounts on the `api` seam `startUiServer` already exposed, so it sits
behind the CG-41 loopback boundary — Host allowlist, no CORS headers,
GET/HEAD only — and every read out of the repository goes through
`resolveProjectFile`, ahead of the index lookup so a traversal is refused
as a traversal rather than reported as "not indexed".

Three properties the endpoints are built around:

- No N+1. The engine's busiest symbol has 545 incoming edges; resolving
  those one `getNode` at a time is 545 queries. Every edge list is
  resolved with one batched lookup, which needed four additive read-only
  query methods (`getNodesByIds`/`getFanIn`/`getFanOut` on `CodeGraph`,
  plus batched outgoing/incoming edge fetches and unresolved-reference
  reads). `/api/node` on `LRUCache.get` answers in ~10 ms.

- Capped lists, honest totals. 545 callers cannot all be rows, so caller
  groups cap at 300 — but `total` is always the real number, and the
  ordering puts the useful end first (same file, then production code,
  then tests). Every count in the payload is the length of a list the
  same payload returns, so a badge and its rail cannot disagree.

- Nothing overclaims. Source that drifted on disk since the last index
  sync is omitted rather than sliced at line ranges that may now point at
  a different symbol; calls that leave the index are counted instead of
  silently shortening the callee rail; imports that never resolved are
  named; and a test-coverage claim reports whether its search actually
  finished. `/api/routes` says a project simply is not routed, and
  refuses a `limit` below three because the engine's manifest would
  answer that question wrongly.

Tests: 45 against a real indexed fixture over a real loopback server,
covering every endpoint's shape, the drift verdict in all three places it
surfaces, search ranking and the filter grammar, the refusals, and the
capping/latency behaviour at 500 callers. The issue's own acceptance case
— `lru-cache.ts` `get` under 100 ms — runs against this repo's index when
one is present.

Colby Mchenry 41c10750e0 fix(erlang): give same-name different-arity functions separate arity-qualified nodes (#1610) (#1615)
Fixes #1610. Also fixes #1358 (the `<<binary>>` arity miscount in behaviour dispatch, reported separately and hit by the same code path).

## Problem

Arity is part of an Erlang function's identity — `f/1` and `f/2` are unrelated top-level definitions — but the extractor merged consecutive same-name `fun_decl`s regardless of arity. Reproduced on main exactly as reported:

- adjacent `f(X) -> …. f(X, Y) -> ….` → **one** node spanning both, with the first definition's signature;
- interleaved `f/1, g/0, f/2` → two nodes with **identical** `qualified_name`;
- `cowboy_req`'s `header(Name, Req) -> header(Name, Req, undefined).` → a **self-loop** `header → header`, with the `-spec` for `/3` swallowed by the merged span;
- `-export([f/1])` marked every arity exported.

## Fix

- **One node per (name, arity).** Clauses of the same name+arity still merge (that part of the old behavior was correct); a different arity starts a new node. `qualifiedName` carries the canonical spelling — `mod::f/1` — while the node **name stays bare** so search and bare-name matching are unchanged.
- **`-export` and `-spec` are per-arity.** `-export([f/1])` exports exactly `f/1`; a spec sitting between two arities attaches to the arity its signature names.
- **Refs carry the call-site arity** wherever it's statically known: local `f/1`, remote `mod::f/2`, `fun f/1` / `fun mod:f/1` values, `gen_server` dispatch (`handle_call/3`, `handle_cast/2`), and spawn/apply MFA lists (`spawn_link(?MODULE, work, [A, B])` → `work/2`).
- **The matcher resolves only to the named arity** — same file first (a local call targets its own module) — and when no definition of that arity exists it resolves to **nothing** rather than a sibling arity: silent beats wrong. An arity-less dynamic-MFA ref resolves only when the module defines exactly one arity of that name.
- **Behaviour dispatch** selects the implementer node of the site's arity, and the arity counter now skips `<<1,2,3>>` binary-literal commas per its own docstring (#1358) — `Mod:decode(<<1,2,3>>, Opts)` counts 2, not 4.
- **`codegraph_explore` / `codegraph_node`** accept the written `mod:fn/3` spelling against the new arity-qualified names (the issue's measured `cowboy_stream_h:request_process/3` shape).

## Validation

Minimal fixtures (all three reported shapes) now index as `gap::f/1` + `gap::f/2`, distinct `inter::f/1`/`inter::f/2`, and a real `deleg::header/2 → deleg::header/3` edge with no self-loop.

Cowboy (fresh `--depth 1` clone, this build vs unmodified main build):

| | main | this PR |
|---|---|---|
| nodes | 3,668 | 3,748 (+80 — the arity splits; no explosion) |
| erlang function nodes | 2,850 | 2,930 |
| behaviour dispatch edges | 38 | **44** |
| `cowboy_req::header` | one node, span 420–425, /3's spec lost | `header/2` (420–421, its own spec) + `header/3` (424–425, its spec) |
| delegation | self-loop | `header/2 → header/3` |

`calls` edges drop 6,059 → 5,656: a sample of every removed pair shows the false-positive class the issue predicted — out-of-repo/BIF calls (`length/1`, `error/1`, `quicer:*`) that previously name-matched onto unrelated same-named in-repo functions now stay unresolved.

Tests: new arity coverage in extraction + a new arity-resolution integration suite + a #1358 binary-literal behaviour test; updated existing Erlang expectations to the arity-carrying spellings. Full suite: **3,018 passed, 0 failed**.

No migration: an existing Erlang index picks the new shape up on its next re-index (`codegraph sync` / re-`init`).

Erlang is wasm-only (not in the native kernel), so there is no kernel-parity surface.

Max HsuandClaude Opus 5 1d9de88ef1 feat(config): add codegraph.json "deprioritize" for ranking-only path down-weighting (#982) (#1463)
* feat(config): add codegraph.json "deprioritize" for ranking-only path down-weighting

matchesNonProductionDir hardcodes example/sample/fixture/benchmark/demo,
so a peripheral tree only the project knows about — optional-skills/,
scripts/ — gets no de-prioritization. When helpers there carry generic
symbol names, an exact name match hands them a large bonus and they crowd
out the product code that answers the query (#982).

deprioritize is the RANKING counterpart to exclude: those paths stay
indexed and findable, they just stop outranking first-party code. It is
deliberately distinct from the corpus-frequency discount, which keys on a
name being common and is near-inert on #982's own repro where only two
symbols are named usage.

The -15 path penalty alone is not enough, and measuring showed why: on
that repro a usage() helper sits at 74.8 against 51.2 for the top product
symbol, so -15 lands at 59.8 and still leads. The path penalty is additive
and the name bonus it must counter is additive and larger. A de-prioritized
path is saying its symbol NAMES are not the answer, so the exact-name bonus
is damped to 0.25x there as well — damped, not zeroed, so the tree still
ranks when it genuinely is what you asked for.

* fix(config): read deprioritize lazily and apply it in explore too

Review of the first cut found two real defects.

The matcher was built once in wireLayers(), which runs only from the
constructor and from reopenIfReplaced(). The MCP server keeps one
CodeGraph per project root alive for its whole lifetime, so editing
codegraph.json appeared to do nothing until the process restarted --
exclude and include do not behave that way. The predicate now reads
loadDeprioritizePatterns() per call (mtime-cached, one stat) and memoizes
the compiled matcher on the pattern array's identity. A regression test
writes the config after opening the project and fails on the old code.

Explore passed no matcher to scorePathRelevance at either of its two call
sites, so the setting only half-applied -- and #982's reproduction rows
B, C and D are all codegraph explore, which made this the surface the
issue actually reports on. Both sites now pass it.

Explore's hard early-continue filters and its non-production budget cap
are deliberately NOT joined: those REMOVE content, and deprioritize is a
ranking lever by definition. README narrowed accordingly -- it previously
claimed this extends the built-in list, which overstated it.

Also from review: scorePathRelevance takes a boolean rather than a
predicate (the caller already evaluated it, and it was being invoked
twice per result), the predicate body is exception-guarded so a bad path
can never take a search down, the misplaced const moved out from between
imports, two vacuous test assertions tightened, and tests added for the
single-penalty invariant, the deliberate isTestQuery asymmetry, and a
query that genuinely targets the de-prioritized tree.

* fix(search): derive the deprioritize name-bonus damping instead of picking it (#982)

The 0.25 scale was a guess. On a 62k-node django index it measurably breaks
the "discount, don't erase" rule the lever is built on: exact-name queries for
symbols that live only in the de-prioritized tree (child, parent, method) fall
behind mere prefix matches (children, all_parents, method_decorator).

The prefix arm of nameMatchBonus tops out below 40, and a de-prioritized node
also takes the -15 path penalty, so 80 * SCALE - 15 > 40 is the bound that
keeps a damped exact match ahead of a prefix match at any corpus shape. 0.75
clears it; crowd-out removal is nearly identical to 0.5 (39 vs 40 of 88
peripheral top-10 slots cleared on django), so the deeper discount bought
almost nothing and cost the invariant.

Two tests pin the bound, including one that fails at the old 0.25.

Max HsuandColby McHenry 9219967e43 perf(search): seek the name index for exact-name lookups (#1542)
`nodes` carries two name indexes and neither can serve
`WHERE name = ? COLLATE NOCASE`: `idx_nodes_name` is BINARY-collated, and
`idx_nodes_lower_name` is an expression index the planner only matches against
the same expression. All three whole-name lookups in the query layer were
written that way, so each one degraded to a full table scan
(`EXPLAIN QUERY PLAN` reports `SCAN nodes`).

The LIMITs on those queries do not rescue them. SQLite can only stop early once
it has produced LIMIT rows, and the two dominant cases never get there: a query
word that names no symbol at all, and a name with only a handful of definitions.
`searchNodes` runs its supplement once per query term; `findNodesByExactName`
runs two passes per symbol extracted from the question, and extraction is
generous, so a plainly-worded question issues a dozen full scans.

Written as `lower(name) = lower(?)` the same predicate seeks
`idx_nodes_lower_name`. Measured on four indexed repositories, baseline vs fix
in one process (the only difference being how the predicate is spelled):

  query "how does the retry backoff work"    findNodesByExactName   searchNodes
    gin         (2.5k nodes)                    1.27ms -> 0.18ms    3.1 -> 2.6ms
    Alamofire   (4.5k nodes)                    2.39ms -> 0.22ms    4.9 -> 4.0ms
    excalidraw  (11k nodes)                    10.54ms -> 0.17ms   10.4 -> 5.8ms
    django      (62k nodes)                    49.91ms -> 0.17ms   27.6 -> 4.9ms

The seek is flat across all four; the scan grows with the corpus. A one-word
query into `searchNodes` on django is unchanged (~20ms) because a single term's
scan is not what dominates it there.

Lowering the parameter in SQL rather than in JavaScript is deliberate. SQLite's
`lower()` and NOCASE both fold ASCII only, while JavaScript's `.toLowerCase()`
folds Unicode; comparing a JS-lowered parameter against `lower(name)` would
silently stop matching non-ASCII identifiers that NOCASE used to match.

`getNodesByLowerName` is spelled the same way for the same reason. It already
sought the index, but as a bare `lower(name) = ?` it took a pre-lowered
parameter on trust: any input carrying an uppercase letter returned nothing at
all. This is behaviour-neutral for its one caller — `matchFuzzy` lowers in
JavaScript before calling, and `lower()` over an already-lowered string is a
no-op, verified over the ASCII and non-ASCII cases alike. It closes the trap for
the next caller; the non-ASCII gap on the `matchFuzzy` side is a resolution
change and is deliberately not bundled here.

Result sets are unchanged, including which rows the LIMITs keep: entries under
one key in the expression index are ordered by rowid, the same order a table
scan produces. Verified over 14,400 lookups (top-400 names of the four
corpora, probed as stored / upper / lower, against all three call sites) with
zero differences, and end-to-end above with identical result ids.

Tests assert the planner's verdict rather than a wall-clock number, so they are
deterministic: they intercept the SQL each call site prepares and require an
index seek, with a guard that the lookups actually ran. Reverting any call site
turns them red.

Colby MchenryandClaude Fable 5 d8f2eeaddf fix(db): loop-append dense unresolved-ref result rows; make stripped-salvage visible (#1558) (#1576)
Real-world validation of #1575 on indexes damaged by the released v1.5.0
binary surfaced both of these.

getUnresolvedReferencesByFiles chunked its INPUT under SQLite's parameter
limit but appended each chunk's RESULT rows with a spread — every row
becomes a call argument, so a dense recovery sync (the #1541 self-heal
re-indexing 919 files produced 234,440 rows) exceeded V8's argument limit
and killed resolution mid-sync with "Maximum call stack size exceeded",
leaving the graph 226k edges short until another sync resumed the orphans
(and that sweep resolves measurably worse than the batched path — see the
follow-up issue). The failed-ref retry loader had the identical pattern on
unbounded result rows. Both append with a loop now (#1558).

The #1575 stripped-salvage warning also never rendered: init's summary
prints only index_partial warnings and counts only hard errors, so a run
with salvaged files still read as fully clean — and with no hard errors the
detail wasn't written to errors.log either. Salvage entries now carry code
'salvaged_stripped', the summary prints a visible warning naming the files,
and errors.log is written for salvage-only runs.

Validated on real corpora with full-graph dumps: healthy-path inits stay
byte-identical to the pre-#1575 baseline (cpython Lib, Alamofire, with a
determinism control); a realistically-damaged index (41 wiped + 5 missing
files, damage generated by the released binary) heals in one plain sync to
identical per-file counts and an edge set within the normal incremental
residual; pathological mass damage (52% of the repo) completes without
crashing. New regression test reproduces the RangeError on the old code
with 200k pending refs.

Colby McHenryandClaude Opus 5 9efae0f8f2 fix(explore): damp ambient declaration files on flow queries (CG-28)
A file that declares nothing but types and that nothing in the index depends
on — a hand-written ambient `.d.ts` of global shims, vendored typings, module
augmentation — cannot answer a flow question: no bodies, no call edges, no
behaviour, nothing typed by it. But the identifiers it declares are exactly the
generic ones a prose question uses (`Body`, `Message`, `ImageMetadata`,
`ReadableStream`), so on term overlap it out-scored the implementation. Measured
on the new fixture: rank #1 and 51% of delivered source, with the flow's own
entry file pushed out of the response entirely.

Measured first, per the issue: the Wrangler `worker-configuration.d.ts` that
opened this is already handled by CG-25's banner detection, worth 15-46 points
of envelope share across four flow queries. CG-25 credited; only the un-bannered
case needed anything.

`rankPenalty` now multiplies score and graph mass by 0.5 for such files, taken
as the STRONGER of it and the generated penalty rather than multiplied — one
property two signals see must not be charged twice. Detection is structural, not
by extension, and four conditions deep. Two of them were forced by measurement:
requiring every symbol to be type-level takes the corpus flag rate from 1-18%
(which swept in Kotlin sealed classes, Rust mod.rs re-exports and django's
locale tables) down to 0-4%; requiring that nothing depends on the file
separates an ambient shim from a working types module, and without it the rule
demoted displacement-ts's pipeline `types.ts` and broke the CG-31 gate.

A query that NAMES a declared type is exempt, so a question about a type still
reaches its declaration at full weight. Precise tokens only, so "…the file
body…" cannot exempt a `Body` interface it never meant to name; this needs its
own set because `namedSeedIds` is callable-only and a type never becomes one.

Regression evidence in docs/benchmarks/explore-declaration-only-cg28.md:
6-repo envelope sweep byte-identical against a clean baseline build, zero
ambient files reach the candidate set on VS Code across five queries, corpus
flag rate 0-0.74%, both allocation fixtures PASS, full suite 2,978 green.

Colby McHenryandClaude Opus 5 03893b0ab9 CG-33: converge incremental sync with a full rebuild
A live, auto-synced index did not converge to a clean rebuild of the same
tree — 4.3% of distinct edges wrong in both directions on this repo's own
index, overwhelmingly `calls`, which is what flow queries traverse and what
explore's file ranking weights. Silent: nothing warned, and the symptom read
as "codegraph isn't very good" rather than "this index needs rebuilding."

Two causes, and the fix needed both. Resolution binds a reference to one of
the same-named definitions PROJECT-WIDE, so a definition appearing or
vanishing changes the correct answer for references in files the sync never
touches — and those references resolved successfully once, which deletes
their unresolved_refs row, leaving nothing to revisit them with (#1240's
retry only revisits refs parked as failed). Separately, when nothing
disambiguated the candidates the winner came down to rowid, i.e. the order
files happened to be WRITTEN, which differs between a scan-order full index
and a sync that appends each file as it changes. That second one is why
re-resolution alone could not converge: re-resolving against the identical
graph still picked a different candidate.

So getNodesByName now orders by (file_path, start_line) — a property of the
code, not of the write order — and sync computes a definitionDelta and
re-opens the resolution edges whose answer it may have invalidated,
re-inserting each as the reference that created it for the orphan sweep to
bind against the post-sync graph.

The delta compares `file\0name` pairs per file rather than one name set over
the batch: a commit that adds `collect` to a new file while an unrelated
changed file already defines `collect` cancels out of a batch-wide set, and
that miss was the largest residual class in the first measurement.

Conservative where the failure modes are asymmetric — a wrong deletion is a
permanent edge loss, a missed rebind is only residual drift. Edges without a
refName stamp are never touched (nothing to restore them from), sources the
sync already re-extracted are skipped, and a per-name ceiling declines the
generic names. Edges are deleted before the sweep re-inserts, since
INSERT OR IGNORE against idx_edges_identity would otherwise keep both rows
when a reference rebinds elsewhere.

Replaying real commits of this repo through sync, then diffing against a
rebuild: 16 commits 48 -> 0; 80 commits 1,634 -> 361, with the actively
misleading direction (stale edges the index keeps asserting) 671 -> 2.
Index and sync wall-clock are unchanged; the ORDER BY costs 18% per uncached
name lookup, which never reaches wall-clock because the resolver memoizes it.

The 357-edge residual at 80 commits is one pre-existing class: refs to
generic names (`push`, `join`) parked above #1240's per-name retry ceiling,
which a rebuild resolves into cross-language garbage — a TS test file
"calling" an R method. Converging there would mean manufacturing wrong edges,
so it is left alone. And no drift metric in `codegraph status`: it cannot be
computed without the rebuild it would be recommending, and a proxy would fire
on that residual and train users to ignore it.

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 Fable 5 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.

Colby MchenryandClaude Fable 5 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).

Colby MchenryandClaude Fable 5 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).

Colby MchenryandClaude Fable 5 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).

Colby MchenryandClaude Fable 5 7cc23668b5 perf(resolution): batch-loop de-quadratic — keyset reads, changes-based guard, DB-scaled valve caps + resolve profiler (#1339)
The §7a.2 per-ref profile overturned the assumption the whole arc was
built on: resolveOne owns only ~93s of the kernel-scale ~433s batch loop.
Loop-stage attribution (CODEGRAPH_RESOLVE_PROFILE, shipped here) named the
rest: backpressure folds 111.2s, count guard 93.9s, batch reads 54.6s,
deletes/inserts/marks ~84s, settle 85.7s.

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

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

Colby MchenryandClaude Fable 5 2adc7f60c0 fix(db): WAL truncate at parked barriers ONLY — the timer-path truncate loses the race it was assumed to lose (#1336)
A truncate checkpoint started against an ACTIVE writer wins the lock and
then blocks that writer for its entire backfill; after the edge-index
recreate's multi-GB single-transaction burst that exceeds the writer's 5s
busy_timeout and fails the index with 'database is locked' (§7a.2 record
run, EXIT=1 at kernel scale — the small mid-resolution truncates folded in
ms and masked the hazard). Barrier truncates (backpressure/foldNow) are
collision-free by construction: the writer is awaiting the valve.

Dubbo gate: exit 0, peak 81MB (barrier folds carry containment), dump
byte-identical. Valve + sizing suites 27/27.

Colby MchenryandClaude Fable 5 ca88d3bd15 fix(db,resolution): WAL file cap + cgroup cache credit + pool/parse sizing corrections from the instrumented kernel-scale runs (#1335)
Four §7a.1 instrumented-run findings, each measured:

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

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

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

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

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

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

Colby MchenryandClaude Fable 5 8c1e821495 fix(db): WAL valve — TRUNCATE at parked barriers, futility latch, CODEGRAPH_WAL_VALVE_DEBUG (#1334)
Three §7a.1 run-1 lessons (kernel-scale 2c/6GB: EXIT=137, WAL 22.2GB with
the backpressure hook DEPLOYED):

1. TRUNCATE at parked barriers: a completed passive backfill bounds the
   un-checkpointed backlog but the FILE only stops growing when a commit
   finds zero readers holding WAL marks — rare while pool workers cycle
   (dubbo debug baseline: file climbed monotonically through six completed
   pass-1 backfills). At a parked barrier the no-reader window is
   guaranteed, so chop the file there with wal_checkpoint(TRUNCATE)
   (off-thread, 2s busy_timeout — a racing reader degrades it to a no-op).

2. Futility latch: when backfill gives up (pinned reader), parking again at
   every over-cap boundary burns a 20-pass checkpoint attempt — each a
   worker thread + fresh connection against a multi-GB DB — per batch. Two
   consecutive give-ups now disable parking for 60s; a pinned phase degrades
   to pre-valve behavior instead of OOM-amplifying.

3. CODEGRAPH_WAL_VALVE_DEBUG=1 surfaces valve decisions without the
   caller's verbose plumbing, and give-up lines print under
   CODEGRAPH_SYNTH_TIMINGS — run 1 failed silently because give-ups were
   verbose-gated.

Colby MchenryandClaude Fable 5 4efc6c70e2 fix(scale): kernel-scale hardening — OOM-safe pass skipping + watchdog-safe index recreate (#1323)
Two hazards found by running today's full stack against the Linux kernel
(70,129 files) in the cg1212 repro container:

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

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

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

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