fix: stop analyze from clobbering customized GitNexus skills (#3124)
* fix: preserve customized SKILL.md files during analyze

Skip overwriting standard GitNexus skill files when they already differ from the bundled template, and keep divergent nested leftovers instead of deleting them.

Fixes #3080

Co-authored-by: Cursor <cursoragent@cursor.com>

* docs: note --skip-agents-md does not skip skills

Point operators at --skip-skills so the AGENTS/CLAUDE skip flag is not mistaken for a full agent-file freeze.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(review): treat unreadable SKILL.md as an error, not missing

Only ENOENT counts as absent so EACCES cannot fall through to recursive rm. Strengthen the skipSkills nested leftover test with a bundle-identical file that install would otherwise delete.

fix(cli): stop churning the committed agent guides, and nudge --index-only (#2907) (#2927)
AGENTS.md and CLAUDE.md are the agent guides teams commit, and the injected
block carried live symbol/relationship/flow counts. Those counts move with any
code change, so every reindex rewrote a tracked file and produced a spurious
diff that had to be restored by hand before committing real work.

The write is now skipped when the volatile counts are the only delta. Counts are
substituted with placeholders — not deleted — before the comparison, so
--no-stats REMOVING the parenthetical is still a material change that writes
through; only a numbers-only difference is suppressed. Both the verbose path and
the gitnexus:keep path go through the same rule, and a project rename, a template
change, or a base_ref change still rewrites as before. Live counts remain
available from `gitnexus status` and `gitnexus://repo/{name}/context`.

Two smaller churn sources go with it:

- The file was CREATED without a trailing newline while every update path writes
  `.trim() + '\n'`, so the analyze right after committing a freshly created
  AGENTS.md dirtied it purely to append that newline.
- `--no-stats` left the per-cluster `(N symbols)` counts in the skills table,
  which are exactly as volatile as the header parenthetical the flag removes.

The stale-index hook recommended plain `gitnexus analyze` — the variant that
rewrites those tracked docs — so an agent following the nudge verbatim reindexed
with the most invasive flags. `formatAnalyzeCommand` takes `indexOnly` and the
three hook call sites (Claude, plugin copy, Antigravity) pass it; the injected
"Index stale?" line and the MCP context resource's `re_index` hint name the same
`--index-only` form. Full `analyze` stays the documented way to refresh the docs
and skills.

Both resolve-analyze-cmd.cjs copies stay byte-identical.

fix: close the nine follow-up review findings from #2856 (routes, receiver typing, truncation honesty) (#2899)
* fix(typescript): a type parameter shadows a declared type of the same name (W2-8)

First item of wave 2, promised to the reviewer on #2856.

`export function unwrap<Result>(value: Result): Result` names the PARAMETER, not
the `interface Result` beside it — tsc resolves both annotations to the
parameter. The type-reference capture that makes a contract answerable ("what
breaks if I remove this field?") had no notion of a parameter binding, so every
annotation mentioning `Result` inside `unwrap` minted a `USES` edge into the
interface, at the same confidence as a real consumer and indistinguishable from
one. Measured on the new fixture: `unwrap` produced TWO false edges while the
genuine consumer produced one.

Blast radius is every generic whose parameter name collides with a declared
type, and the colliding names are ordinary choices for both: `Result`, `Key`,
`Value`, `Item`, `Node`, `Options`, `Config`, `Props`, `State`, `Response`.

TWO HALVES, and the first is why upstream's fix could not reach this. #2833
introduced `bindsTypeParameter` for the CALL-receiver path, where a workspace
`class T` was answering for `<T>`. Reusing it here changed nothing at first, and
the reason is its own documented contract: `@declaration.type-parameters` was
captured for class/interface declarations ONLY, so a generic FUNCTION recorded
no parameter list and the predicate correctly returned false — absence is not
evidence. The data was missing, not the logic. So:

  - TYPESCRIPT_SCOPE_QUERY now captures type parameters on `function_declaration`,
    `generator_function_declaration` and `type_alias_declaration`;
  - the graph bridge consults `bindsTypeParameter` before emitting `USES`.

Both are load-bearing — removing either one fails the fixture.

The fixture carries two controls, because the obvious wrong fix is to stop
emitting: a genuine consumer of the interface must still link, and a generic
whose parameter does NOT collide must still link its real reference. Both are
asserted, and the "genuine consumer" case is asserted FIRST so the absences
below it cannot pass vacuously.

SCHEMA_BUMP 53 -> 54: parse-time capture change. A warm cache replays defs with
no parameter list, so the guard reads nothing and the feature is inert while
looking implemented.

Capture fingerprint re-baselined with justification. NO NEW CAPTURE NAME —
diffing the capture-name sets against the wave-1 branch returns empty; the tag
existed and now fires on more declarations. capture_groups_fp 2338 -> 2371,
fixture_count 151 -> 152, scaling 1.06 < 1.5, and JavaScript's fingerprint does
not move at all, which is the check that this is the TS declaration rules rather
than something broader.

* fix(analyze): close the four false-success paths in the graph-write-collapse guard (W2-6)

Second wave-2 item, promised on #2856. All four were reported; all four
reproduced by reading the code they name.

(a) A SAME-COMMIT RE-RUN REPORTED SUCCESS FOREVER. Every other meta-driven
    trigger — schema fingerprint, PDG mode, runner identity, CJK segmentation,
    embedding dims — has a block that forces a rebuild before the
    `alreadyUpToDate` fast path. `graphWriteCollapsed` had none; `grep -rn` found
    writes and no reads. So the one state meaning "most of your edges are gone"
    was the one state that repaired itself only if the user happened to pass
    `--force`. Now forces a full rebuild, and forcing is right rather than merely
    re-running: the persisted graph disagrees with what the pipeline produced, so
    an incremental pass over unchanged files would write nothing and re-stamp the
    same broken index as fresh.

(b) AN INCREMENTAL RE-RUN ERASED THE STAMP. `saveMeta` is a full atomic
    overwrite, and the field was spread in only when the CURRENT run had a
    verdict. `undefined` meant two different things at that site — "full run, no
    collapse" (a positive all-clear) and "incremental write, not comparable" (no
    opinion) — so the second case silently dropped `graph-write-collapsed` from
    meta.json while the edges were still missing. Now three-way: stamp on
    detection, CLEAR on a healthy full run, CARRY FORWARD when there is no
    verdict. That is the shape `branch: branchLabel ?? existingMeta?.branch` two
    lines away had all along.

(c) THE SERVER PATH NEVER CONSUMED IT. `analyze-worker-ipc.ts` projects the field
    "so a server-side caller sees the same degraded outcome the CLI does" — but
    nothing read it, so the comment described an intention and every collapsed
    run reported `complete` to the UI and to every API consumer. Now reports
    `failed` with the counts and the remedy, matching the CLI, which prints
    `Repository indexed INCOMPLETELY` and exits non-zero. A consumer that reads
    "complete" will query the index and get confident wrong answers.

(d) --pdg ROWS MASKED TOTAL STRUCTURAL LOSS. `expected` counts the in-memory
    graph plus the streamed STRUCTURAL manifest; the streamed PDG layers never
    enter `graph.relationshipCount`. But `persisted` was `stats.edges`, a count
    of EVERY `CodeRelation` row, and PDG writes into that same table. With 1,000
    structural edges expected and 4,000 PDG rows persisted, losing every
    structural edge still read `persisted = 4000`, cleared the ratio, and stayed
    silent — on exactly the large repos `--pdg` is used for.

    Worth recording that the OBVIOUS fix does not work. Padding `expected` with
    the PDG rows makes the two universes match but leaves the ratio judging a
    minority population: 4,000 of 5,000 still clears 0.5. I wrote that first, and
    the test I wrote to prove it failed. Only comparing structural against
    structural asks the question the check exists to ask, so `getLbugStats` gains
    a `structuralEdges` count excluding `PDG_EDGE_TYPES`. `TAINT_PATH` is
    deliberately NOT in that set — it is a whole-program Function→Function edge
    persisted by the normal emit, so it is structural and stays counted on both
    sides.

    `index-freshness-graph-collapse.test.ts` had pinned the masking as correct
    (`detectGraphWriteCollapse(1000, 4000)` → undefined, "PDG layers write into
    the same table, so persisted > expected is normal"). True about the table,
    and it licensed the hole. Replaced with the case that matters and a note on
    why the fix is at the caller.

The new `structuralEdges` assertion in `lbug-core-adapter` is there because the
failure mode is silent: the query sits in a try/catch that yields `undefined`,
and `undefined` makes the collapse check decline to compare — so a typo in the
Cypher would throw nothing, fail nothing, and switch the guard off. Verified
against a real LadybugDB and mutation-checked by breaking the query.

* fix(processes): make process selection insertion-order invariant (W2-5)

Third wave-2 item. Reproduced before fixing: two equal three-step flows with
`maxProcesses: 1` select `handleAlpha`; inserting the identical nodes and CALLS
edges in reverse select `handleBeta`. Same repository, same commit, a different
persisted graph — so a filesystem that enumerates differently, or an incremental
run that reorders assembly, silently changes what the tool reports.

Four sorts ranked by score or length alone and returned 0 on a tie.
`Array.prototype.sort` is stable, so a 0 preserves INPUT order, which traces
back to `graph.iterNodes()`. Under `maxProcesses` capping that decided which
`Process` and `STEP_IN_PROCESS` nodes were persisted at all. Each now falls
through to a totally-ordered, content-derived key — node id for entry points,
the joined path for traces.

WHAT IS ACTUALLY VERIFIED, stated precisely because "four fixes" would overclaim:

  - the ENTRY-POINT sort is individually mutation-verified;
  - the two DEDUP sorts are collectively mutation-verified;
  - the TRACE-RANK tiebreak is NOT individually observable, and the source says
    so. The dedup sorts already impose a total order on the list that reaches
    it, so removing it alone fails nothing. Kept as defence in depth: it cannot
    misbehave — it only makes an already-deterministic order explicit — and it
    is what stops a change to dedup ordering from silently re-opening this.

Finding that out took two fixtures. The first (three chains, three entry points)
is separated by the entry-point sort before trace ranking is reached, so it never
exercises the trace comparator at all; the second gives ONE entry point two
equal-length branches to different terminals, which is the only shape where the
trace comparator decides. Both are kept — they gate different sites.

The invariance tests assert the INVARIANT rather than any single sort, so they
cover all four sites and any future one without needing to know where they are.
Three assertions: same selection under a cap, identical set uncapped, and
identical ORDER — the last because order is what the cap consumes, so a set-only
assertion would pass while the defect persisted.

* fix(impact): UNKNOWN dominates a mixed candidate set, instead of reporting the known floor (W2-4)

Fourth wave-2 item. The all-UNKNOWN branch here was reasoned about carefully and
is correct — its comment even names the two ways a set can be all-UNKNOWN. The
MIXED case fell straight through it.

`RISK_ORDER` is `['LOW','MEDIUM','HIGH','CRITICAL']` and has no `UNKNOWN` entry,
so `indexOf('UNKNOWN')` is -1 and an UNKNOWN candidate can never win the reduce.
An ambiguous name with one caller-less candidate (UNKNOWN, per the round-1 fix)
beside one single-caller candidate (LOW) reported `maxRisk: 'LOW'` — a confident
floor over a set containing an interpretation nobody measured. That is the same
false-safe the all-UNKNOWN branch exists to prevent, one case over, and it
surfaced in the UI as "Max blast radius N (LOW risk)".

`maxRisk` answers "how bad could this be?", and an unresolved candidate could be
CRITICAL — so any UNKNOWN in the set makes the aggregate UNKNOWN. Narrowing it
that way would normally cost information, so the measured part travels alongside
as `knownMaxRisk`, present only when the two differ: absent on a fully-resolved
set, where it would duplicate `maxRisk`, and absent on a fully-unknown one, where
there is no measured part. A reader gets "at least LOW among what resolved, and
one interpretation could not be walked at all", which is strictly more than
either value alone. The human-readable message says the same thing.

The seed gained a mixed pair because the existing one could not reach this: both
its twins are caller-less, so it only ever exercises the all-UNKNOWN branch —
which is precisely why the gap survived a round of review. Three assertions,
both halves mutation-verified.

`eval-server.ts` needs no change: it renders `result.maxRisk ?? 'UNKNOWN'`, so it
now shows UNKNOWN where it previously showed the floor.

* fix(routes): track ternary polarity in dispatch guards, so a selected verb cannot be inverted (W2-9)

`if ((req.method === 'GET' ? false : true) && pathname === '/api/i')` emitted
`GET /api/i` — the one method that branch guarantees the request does NOT have.
A ternary SELECTS between its arms, so a verb inside one is not reached merely
because the whole condition is truthy, but `findVerbInSubtree` descended into
both arms and returned the first verb it saw. Same inversion `!` produced before
d4dcba8c, one level up.

Handled by folding the ternary where an arm is a boolean literal, which is what
collapses the selection into a conjunction:

    c ? A : false  ==  c && A     both hold, so search both
    c ? false : B  ==  !c && B    c must NOT hold, so search it at flipped parity
    c ? true : B   ==  c || B     a disjunction guarantees neither operand
    c ? A : true   ==  !c || A    likewise

Two non-literal arms leave the verb chosen by an unknown condition, so the
ternary guarantees nothing. Refusing every ternary would also have fixed the
reported bug, but three of the four shapes measured were ALREADY correct and
would have silently lost their verb; they are pinned now.

A second defect in the same walk, found while reproducing: the `!` rule was
keyed on PRESENCE, returning null at the first negation it saw, while
`isNegatedContext` two functions above states the rule is PARITY and says so
outright — `!!x` is `x`. So `!!(req.method === 'GET')` dropped a verb the source
states plainly. The existing double-negation test covered the PATH position,
where the parity walk already ran, and so never saw it. The verb walk now tracks
parity too, and the two agree.

Verb-less, not route-less: the path comparison is untouched evidence that the
branch serves that path, so an inverted verb becomes a missing verb rather than
a missing route.

SCHEMA_BUMP 54 -> 55. Routes are emitted at parse time and replayed verbatim
from a warm cache, so without the bump an already-indexed repo keeps serving the
inverted verb and the fix looks inert. Free against origin/main (48).

Every rule mutation-checked: removing the ternary dispatch, either literal-arm
rule, the negated-ternary guard, or the parity walk each fails exactly the tests
that claim it. One assertion I wrote survived all five mutations and was removed
rather than kept.

Not a recall win on crypto-trading-bot, which contains neither shape — this is
precision insurance for dispatchers that do.

* feat(routes): report every method a dispatch guard serves, not just the first (R3-8 part 1)

`if ((req.method === 'GET' || req.method === 'POST') && bundlesMatch)` is two
routes. The verb walk returned the FIRST verb it found, so `route_map` presented
a two-method route as GET-only and `impact` on the POST path found nothing.
Taken verbatim from the reporting repo's researchRunRoutes.js.

`governingVerb` -> `governingVerbs`, returning a list; `findVerbInSubtree` and
`verbFromTernary` likewise. A guard with several verbs emits one route per verb
via the new `pushPerVerb` — they share a path and a handler but not a method,
and `(method, url)` is the key every downstream consumer dedups and looks up on.

A disjunction yields ALL its verbs or NONE, which also fixes an over-attribution
the first-match rule had:

    req.method === 'GET' || req.method === 'POST'   ->  GET, POST
    req.method === 'GET' || isAdmin                 ->  no verb

The second is reached for ANY method when `isAdmin` holds. Reporting `GET` — as
first-match did — describes a route open to everything as single-method, which
is the direction this module treats as more expensive than saying nothing.
Negated, `!(A || B)` is `!A && !B`, so it excludes verbs rather than offering
them and yields none.

Generic descent deliberately stays FIRST-match rather than unioning across
children: an arbitrary node says nothing about how its children combine, and two
verbs found under one are far more likely unrelated than alternatives. `||` is
the one construct that genuinely means "either of these".

Pinned against regression: the pre-existing rule that distributes ONE verb
across an OR of PATHS must not start multiplying methods, and switch arms
inherit the full method set.

SCHEMA_BUMP 55 -> 56. Routes are parse-time output replayed verbatim from a warm
cache. Free against origin/main (48).

Four mutations, each failing exactly the tests that claim it: removing the
disjunction dispatch, dropping the all-operands rule, allowing a disjunction at
odd parity, and emitting only the first verb.

* feat(routes): read `.match()` dispatch, and the capturing wildcard it needs (R3-8 part 2)

`RE.test(pathname)` and `pathname.match(RE)` are the same test with the operands
swapped. Only `.test` was read, which is why 28 of the reporting repo's 75 routes
still named the shared route table as their handler rather than the module that
serves them: those modules dispatch with `.match`.

THE CAPTURING WILDCARD, which is the part that made the rest inert.
`regexToRoutePath` accepted `[^/]+` and refused `([^/]+)` — `(` fell through to
the metacharacter bail. So the non-capturing form translated and the capturing
form produced nothing, and every existing test passed because every existing
test used the non-capturing form. The tests were written against the
implementation rather than against the corpus, and the reporting repo contains
no non-capturing path wildcard at all: a dispatcher captures the segment because
it needs the id. This alone also repairs the already-shipped `.test` rule.
A capture around anything that is NOT one segment still bails — `(.+)` spans
slashes — and the alternation is balanced, so `([^/]+` unclosed is not a match.

`.match` differs from `.test` in one way that matters: its result is USED, so it
is almost always BOUND, and the verb then lives in a later `if`:

    const runMatch = pathname.match(/^\/api\/research-runs\/([^/]+)$/)
    if (req.method === 'GET' && runMatch) { … }

Reading the verb off the CALL would report every one of those verb-less. So a
bound match records `name -> path` and the route is emitted where the binding is
TESTED, once per test site — one binding tested for GET and for PUT is two
routes. A reference counts only in a truthiness position (`&&`/`||` operand, or
a whole `if` condition), which is what separates `if (m && …)` from `m[1]`: a
read of the captured segment says nothing about dispatch and would otherwise
mint a duplicate route per use of the id. A binding never tested still emits one
verb-less route — the code did compute an anchored match against the path.

Regexes named by a same-file const resolve too (`pathname.match(POSITION_REPLAY_RE)`),
with the same ambiguity refusal the string-constant map uses: bound twice to
different patterns means dropped, because a half-right regex is a wrong route.

SCHEMA_BUMP 56 -> 57. Free against origin/main (48).

Nine mutations, each failing exactly the tests that claim it. TWO of my own
tests initially survived their mutation and were rewritten, not kept:
- the non-path-receiver case had no path token anywhere in the fixture, so
  PATH_TOKEN_HINT skipped the file and the assertion was satisfied by a file
  that was never examined;
- the negation case used `!m`, which never reaches the negation check at all —
  a `unary_expression` parent is not a truthiness position to begin with. The
  shape that exercises it is `!(req.method === 'GET' && m)`.
A declaration-site skip written alongside them proved unreachable for the same
reason and was removed rather than left to imply a hazard.

* feat(processes): report what the detection ceilings dropped, instead of logging it at debug (W2-3)

`processProcesses` has five ceilings - the entry-point trace quota, the
per-entry trace budget, `maxTraceDepth`, `maxBranching` and `maxProcesses` -
and every one of them fired silently. The result came back looking whole and no
consumer could tell it was a sample. The code's own comment already said so:

    // A silently truncating cap reads as "this is everything", which is the
    // same class of confident-empty answer this work is about.

and then only called `logger.debug`. A log nobody has enabled is not a
disclosure.

`stats.truncation` is additive, so every existing consumer of `totalProcesses` /
`crossCommunityCount` / `avgStepCount` / `entryPointsFound` is unchanged. It
carries one boolean to branch on plus a counter per ceiling, kept SEPARATE
rather than summed because they mean different things: unexplored entry points
mean whole flows are missing, while a depth-capped trace means a flow is present
but shorter than it really is.

`processesDropped` counts against the DEDUPED population, not the raw trace
list - the gap between those two is deduplication doing its job, and counting it
as truncation would report a permanent non-zero on every healthy repo.

`truncated` is DERIVED from the counters rather than set at each site, so a
ceiling added later only has to increment its own counter to be reported.

Surfaced at `warn` and NOT gated on `isDev`: "823 flows" printed without it
reads as the complete set, which is the confident-empty failure wearing its
other face - a confident-COMPLETE one. The debug line stays for the per-entry
detail it carries.

Seven mutations, each failing exactly the tests that claim it, including BOTH
directions of the flag: hardcoding `truncated` false fails the four positive
cases, and hardcoding it true fails the nothing-was-truncated case, which is
asserted first precisely so the positives cannot pass vacuously. The
`walksCutByBudget` fixture gives every node exactly `maxBranching` callees so it
asserts its own counter and not a neighbour's.

Also fixes a defect this work exposed: 10b0c7a1 (W2-5) embedded a RAW NUL BYTE
in `trace.join(...)` instead of the backslash-u escape the rest of the repo
uses. It behaves identically at runtime, but `file` reports the source as
`data`, and grep, git diff and code search treat it as binary - several greps
against this file silently returned nothing while I was reading it. main was
clean here; two other files carry the same raw byte from before this branch and
are left alone.

* feat(scope-resolution): resolve members through a MEMBER-CALL producer's return shape (W2-1)

    const svc = new SignalService()
    const r = svc.make()
    return r.secretFlag        // <- no edge

`return-shape-members` types `r` to the producer that made it, but a member call
binds the spelling `svc.make`, and slicing that to its last segment leaves
`make` — a METHOD, never a callable binding in scope. The producer lookup failed
and the pass declined.

The limit shipped documented as needing inter-procedural receiver typing. It does
not. Measured on a fixture, the pipeline had already done the hard part:

  - `readMake -> Method:...SignalService.make#0` already resolves as an ordinary
    CALLS edge, so the receiver is already typed; and
  - `Property:...SignalService.make.secretFlag@N:C` already exists, because R3-4
    anchors a returned literal's keys to the METHOD that returns them, not only
    to free functions.

Both halves were present and unjoined — the same shape as R3-5 itself.

ADDITIVE, not a reroute. The new branch sits inside `if (producerFile ===
undefined)`, so it can only fire where the callable lookup already declined;
every reference that resolved before resolves identically, by construction
rather than by test.

Nothing new is inferred. The receiver is typed by the SAME predicate that typed
`r`, and it must itself resolve to a class — a receiver that cannot be typed
still declines, so `make.<member>` is never matched by name across the graph.
That fabrication is what the existing guards exist to stop and they all carry
over unchanged: the owner must resolve, its file must match the candidate's, and
`ownFilePaths` keeps the polyglot class registry from walking a JS read into a
Java field.

The owner segment is TWO parts for a method (`SignalService.make`) and one for a
free function (`makeSignal`), which is exactly how R3-4 qualifies each. That is
what separates two methods of one class returning the same key name from each
other AND from a free function of that name — the fixture gives `secretFlag`
three owners so a wrong resolution is detectable rather than a coin flip that
happens to look right.

Four mutations, each failing exactly the two tests that claim it: removing the
fallback, using the method alone as the owner segment, taking the producer file
from the reading file instead of the owner class, and dropping the
receiver-type requirement. 3,408 resolver tests pass, including
`polyglot-property-isolation`, which is the one this could plausibly break.

No SCHEMA_BUMP: this is a resolution pass over ParsedFiles, not parse-time
output, so a warm cache replays the same input and produces the new edges.

Measured on crypto-trading-bot: ZERO new edges, byte-identical at 62,158. Its
170 `const x = new Y()` bindings are overwhelmingly built-ins (Map, Set,
Promise, S3Client) rather than workspace classes whose methods return object
literals — it is a module-style JS codebase. Correctness fix for class-shaped
code, not a recall win on this corpus, and it should not be presented as one.

* feat(scope-resolution): type a bare parameter from what its callers pass (W2-2)

    function readSpike(spike) { return spike.wickRatio }

had nothing to type `spike` from, so the read fell through to the 0.5 name tier.
That is the standing limit of R3-5 and, measured, by far the largest: 11,012 of
13,672 property edges on the reporting repo (81%) rest on that name guess.

The two facts needed were already extracted, for a different consumer. For JS
and TS among others, `callable-flow-captures` synthesizes:

    formal    owner=readSpike  binding=spike  parameter-index=0
    argument  source=s  parameter-index=0  direct-callee-name=readSpike

Joining them on (callee, parameterIndex) says which cell reaches which
parameter, and the argument's own binding is typed by the same
`findReceiverTypeBinding` a directly-bound receiver already uses. So the
parameter inherits the producer and `spike.wickRatio` resolves as evidence
rather than inference.

No new capture, no parse-time change, NO SCHEMA_BUMP. And deliberately not a
change to the callable-value-flow solver that owns these sites: that pass is
guarded by a fingerprint CORRECTNESS gate plus a timing budget, so this reads
the same facts and computes its own map.

AMBIGUITY DECLINES. A parameter whose callers pass different producers resolves
to nothing. Picking one would fabricate at the 0.9 PRECISE tier, which no
`minConfidence` floor can filter out — the same reason `buildConstantMap` drops
an ambiguous constant instead of taking the first.

Keyed by the formal's (scope, name), not by a definition id. The first attempt
used a def and measured `paramDef=NONE`: a parameter is not reachable through
`findValueBindingInScope` (its predicate is `isOwnableValueLabel`, which lists
Const/Variable/Property/Static because it exists for OWNERSHIP registration, and
a parameter is owned by nothing) and it is not a `local` binding either. The
formal site already states the scope its parameter binds in, which is enough.

Formals carry their DECLARING FILE in the key, so two same-named functions in
different files cannot answer for each other — dropping it makes both go
ambiguous and both readers silently lose their edge.

COVERAGE, counted rather than assumed. The synthesis skips an argument that is
itself a call result (an explicit `continue` in `callable-flow-captures`), so
`f(makeSignal())` emits no argument site and only the bound spelling
`const s = makeSignal(); f(s)` is served. That looked fatal until measured: in
the reporting repo, bare-identifier arguments outnumber call-result arguments
2,563 to 50 — 51:1. Extending the shared, benched capture synthesis for the 2%
case is not worth its risk.

Four mutations, each failing exactly the tests that claim it: keeping the first
producer instead of declining on conflict, dropping the read-site lookup,
matching a formal at index 0 regardless of the argument's index, and dropping
the declaring file from the formal key. Two of those could not be caught by the
first fixture at all — it had a single parameter and a single consumer file — so
the fixture gained a two-parameter callee and a same-named twin in a second file
before they were meaningful. The test helper also had to start filtering by
source FILE, or two different `readSpike` symbols merged into one count.

Measured on crypto-trading-bot: 36 reads left the 0.5 name-guess tier. 26 became
precise 0.9 edges (return-shape reads 1,130 -> 1,156, which is the whole delta),
and 10 became honest absences — the receiver was typed, the producer's shape was
known, and the member is NOT on it, so the site is claimed as disproved rather
than left for the name fallback to invent an answer for.

That is ~0.3% of the 11,012, and it should be reported as such. The 81% figure
is the size of the PROBLEM, not of this fix: the shape requires a bound
argument, a producer that returns an object literal, and a parameter read as a
receiver, and that intersection is narrow. The remaining name-tier reads are
mostly receivers no workspace producer types at all.

* fix(processes,ci): anchor trace subsumption, cover the sink wiring, stop one bench guard hiding the rest (#2894, #2896, #2895)

Three follow-ups reported against #2856 after it merged. Each was reproduced
before it was fixed.

#2894 — trace subsumption matched mid-identifier.

`deduplicateTraces` decided whether one trace is a sub-path of another with an
UNANCHORED `String.includes`, so a match could begin in the middle of a node id:

    'X->AA->B'.includes('A->B')   ->   true

and `A -> B` was discarded as redundant against a chain `A` is not a step of at
all. Reproduced directly against the function before fixing.

Padding both keys with the separator makes `includes` match whole steps only.
Reported as measured-inert and that holds — the collision needs one node id to
be a strict suffix of another at a `->` boundary, which real ids
(`Function:<path>:<name>`) do not produce. Fixed anyway because the predicate
did not mean what the surrounding code says it means, in a function whose entire
job is deciding what to delete, and nothing pinned it.

`deduplicateTraces` is exported for the test, matching how `traceFromEntryPoint`
and `buildSinkFunctionSet` are already reached. The tests use bare ids because
the shape cannot be built from realistic ones — which is exactly why nothing
caught it. Alongside the regression case, two tests pin that GENUINE subsumption
still happens, prefix and suffix, so the fix cannot degenerate into "subsume
nothing" and pass the first test trivially. Mutation-checked: reverting the
padding fails the mid-identifier test and only that one.

The encoding assumes `->` never appears IN a node id; a C++ `operator->` would
defeat the join regardless of padding. Out of scope, but the assumption is now
written down where the join happens.

#2896 — the sink wiring was only ever exercised through its fail-open catch.

`processesPhase` reads `allFetchCalls` / `allORMQueries` off the parse output
inside a try/catch that falls open to "no sinks", and every phase-level test
omitted `parse` — so all of them took the CATCH branch and the success path had
no coverage. `getPhaseOutput` is a raw `as T` cast, so a field rename would make
the phase detect zero sinks while every test still passed, because zero sinks is
what they already assert.

The new test asserts the one thing only the success path can produce: a flow
ENDING at the sink while a longer chain continues past it. Its control is the
same graph with no `parse` dep, which must NOT produce that terminal — without
the control the assertion could pass for an unrelated reason. Also asserts
`processesPhase.deps` contains `parse`, so the read and the declaration cannot
diverge, and that a parse output missing those fields still fails open rather
than losing every process.

Mutation-checked, including the exact drift scenario reported: renaming
`allFetchCalls` at the read site, dropping `parse` from `deps`, and passing no
sinks to `processProcesses` each fail exactly the test that claims them.

#2895 — a failing bench guard aborted the job and masked every later guard.

Every step in the benchmarks job was fail-fast, so the first failing `--check`
aborted it and the rest reported `skipped`, which reads identically to "nothing
to do". Audited over 13 runs on #2856: the job succeeded zero times and the last
two guards executed zero times for the life of the PR, while two reviews read
the checks summary and saw nothing wrong. Both guards did in fact pass — that
was luck, not verification.

`if: ${{ !cancelled() }}` on all ten steps after the first, so one stale
baseline reports one red step instead of hiding nine. `!cancelled()` rather than
`always()` so an explicit cancel still stops the job instead of running seven
minutes of benchmarks nobody is waiting for.

The two steps easiest to miss are covered: `Receiver-resolution drop guards`,
whose `run:` sits twenty lines below its `name:` behind a long comment, and the
final `Cross-language pipeline benchmarks` step, which is not a `--check` and so
falls outside any grep for one — and is one of the two that never ran.

* fix(parse): capture a fetch call site even when its URL is not a literal (#2897)

The `fetch` rule required the argument to be a string or template literal:

    arguments: (arguments
      [(string (string_fragment) @route.url)
       (template_string) @route.template_url])

so `fetch(url)` with a variable matched nothing at all. Measured across this
repository's own TypeScript sources: **44 of 47 fetch calls pass a variable**, so
94% produced no site.

That is what makes R3-6 look inert. The sink set is built entirely from
`allFetchCalls` / `allORMQueries`, so a function performing an outward call
through a computed URL was never a sink, no flow could terminate there, and the
sink-first ranking rule never changed an ordering. The feature was fine; the
signal underneath it was almost always empty.

The URL alternation is now OPTIONAL, so one match covers both shapes. The R3-6
sink set needs only WHERE the program reaches outward, not where to.

Route linking is untouched, by construction rather than by hope:
`processNextjsFetchRoutes` normalizes the URL first and skips anything that
yields nothing, so a URL-less entry cannot mint a FETCHES edge. Verified on this
repo — FETCHES went 8 -> 9 across the change, i.e. the widening added sink sites
without inventing route edges, which was the one real risk here.

Tested in BOTH JavaScript and TypeScript, since the rule is duplicated in each
query block and fixing one would have left the other blind:

  - a variable argument is captured, with no URL   <- the regression case
  - a computed argument (`fetch(buildUrl(), {...})`) likewise
  - a literal URL is still captured WITH its URL   <- route linking depends on it
  - a template URL likewise
  - exactly ONE site per call — an optional alternation must not make a literal
    match twice, which would double-count the site and could mint two edges
  - `prefetch('/x')` is still not a fetch

Mutation-checked: restoring the mandatory alternation fails six of the twelve,
three in each language.

SCHEMA_BUMP 57 -> 58. Parse-time capture output is replayed verbatim from a warm
cache, so without the bump an already-indexed repo keeps its empty sink set and
the fix looks inert — which is the failure this constant exists to prevent, and
would have reproduced the very symptom being fixed.

Not addressed here, and worth stating: this widens `fetch` only. The reporter's
broader point stands — anything keyed on FETCHES / QUERIES is only as good as
the extraction underneath it, and the ORM side has not been measured. A guard
that fails when a corpus known to contain outward calls yields zero sites is the
right follow-up; this change makes such a guard meaningful rather than
tautological.

* test(bench): re-baseline receiver-resolution for the two fixtures this PR adds

`receiver-resolution --check` failed on:

    countArm.totalDropsAllKinds: 140 -> 148
    countArm.bySiteKind.write:    11 ->  19

Investigated before touching the baseline, because a guard that exists to catch
unexplained movement should not be silenced by an unverified story.

WHAT IT IS: the count arm runs the real pipeline over a corpus that includes
`test/fixtures/lang-resolution/`, and this PR adds two fixtures there —
`member-call-producer` (W2-1) and `parameter-producer` (W2-2). Each returns an
object literal with two keys, and a producer writing its own returned key is a
write site the receiver recorder logs. Four each, eight total.

Attributed by dumping the individual drops rather than reading the aggregate:

    member-call-producer/src/producer.js   secretFlag, wickRatio  (2 lines) = 4
    parameter-producer/src/producer.js     source, wickRatio      (2 lines) = 4

The eleven drops already in the baseline are all `javascript-object-properties`
fixtures of exactly the same shape, so the new ones are not a new KIND of drop —
they are more of one the baseline already records. This is the first case the
guard's own failure message names: "a fixture was added".

WHAT IT IS NOT: `callDrops` — THE gate number, and `call`-only by deliberate
design because reads and writes "would inflate it" — is unchanged at 102. `read`
drops unchanged at 27. The SHAPE ARM shows no drift at all: no receiver spelling
moved between RESOLVES / VISIBLE-GAP / INVISIBLE-GAP, so no resolution
regressed.

HOW IT WAS ISOLATED, since the first attempt was misleading and the record is
worth having: reverting `return-shape-members.ts` alone did NOT reproduce it and
pointed away from W2-1/W2-2. Only a commit-level bisect was trustworthy —
`origin/main` OK, W2-8 OK, W2-3 OK, then W2-1 +4 and W2-2 +4, which matches the
fixture count exactly. A file-level revert leaves the fixtures in the tree, and
the fixtures are the cause.

The update is two numbers. Nothing else in the baseline moves.

Worth noting where this failure became visible at all: under the fail-fast
benchmarks job it would have aborted the run and shown the five guards after it
as `skipped`. It is legible here because #2895 — fixed in this same PR — now
lets every later guard run.

* fix(analyze): stop `--pdg` runs reporting a healthy index as INCOMPLETE

Every `gitnexus analyze --pdg` reported a graph-write collapse and exited 1 on an
index where every row had persisted. Reported by a user hitting it on a real
repo; introduced by this PR's own W2-6(d).

    Repository indexed INCOMPLETELY
    the pipeline produced 200,501 relationships but only 64,764 are readable

The index was complete: 200,190 rows present, 109,905 PDG and the rest
structural, all queryable.

WHAT WENT WRONG. W2-6(d) made the persisted side count STRUCTURAL rows only —
correct, and the reason is in its own comment: PDG writes into the same table, so
counting everything let PDG surplus mask real structural loss. But the expected
side kept using `graphEmitManifest.totalRows`, and that is a BUFFER-POOL SIZE
HINT which counts every streamed row. PDG streams through that same sink, so the
check compared a structural-plus-PDG expectation against a structural
measurement. On any repo with a PDG layer that is a guaranteed false collapse.

It compounds rather than merely misreporting: the run stamps
`graph-write-collapsed`, and W2-6(a)'s rebuild trigger — added alongside it —
forces a full re-analyze next run, which collapses again. A permanent rebuild
loop, on an index that was never damaged, at ~100s a cycle.

MEASURED RATHER THAN ASSUMED, because the first attempt was wrong. I first
subtracted PDG edges RESIDENT in `graph.relationshipCount`, rebuilt, re-ran the
failing command and got byte-identical numbers. Instrumenting the three terms
showed why:

    relationshipCount=20,825  graphManifestTotalRows=179,676
    pdgEmitManifest=absent    residentPdgInGraph=0

PDG is not resident in the graph AND has no separate manifest — it streams
through the ordinary `GraphEmitSink`. The reverted attempt is not in this diff.

THE FIX. A pair key cannot separate them: it is `From|To` NODE LABELS, and a CFG
edge shares `Function|Function` with CALLS. Only the write path sees
`relationship.type`, so the sink now counts a `structuralRows` subtotal there and
publishes it on the manifest. `totalRows` is unchanged — it still sizes the
buffer pool, which is what it was for.

WHY THIS SHIPPED UNCAUGHT, and what changed about that. The wiring test kept a
LOCAL MIRROR of the expected-count expression "because the production expression
is inline in a 3000-line function". A mirror cannot catch a term the original got
wrong. That expression is now an exported
`computeExpectedStructuralRelationships` which production calls and the test
imports.

It also takes the MANIFEST rather than a pre-selected number, deliberately: the
defect was choosing the wrong FIELD, and a numeric parameter leaves that choice
at a call site no unit test can reach. Verified — with the helper taking a
number, reverting to `totalRows` failed nothing; taking the manifest, the same
revert fails four tests.

Verified end to end on the reported command: `analyze --force --embeddings 0
--pdg` now exits 0 with "indexed successfully", 86,963 nodes / 200,217 edges, and
the run clears the stale collapse stamp.

* fix(routes): scope match bindings, and intersect ternary conjunctions

Two ways the dispatch-guard walk minted a route that does not exist — the one
thing this module's header says is worse than missing one.

MATCH BINDINGS WERE KEYED BY BARE NAME, FILE-WIDE. `collectFromMatchBindings`
walked from `tree.rootNode` and resolved `matchBindings.get(node.text)` at every
identifier in a truthiness position, so a same-named binding in ANOTHER function
answered for it. The poison check only fired on a second REGEX match with a
different URL; a non-match binding never entered `collectFromRegexDispatch`, so
nothing refused it. Reproduced:

    function handleReplay(req, res) {
      const m = pathname.match(/^\/api\/live\/positions\/([^/]+)\/replay$/);
      if (req.method === 'GET' && m) { … }
    }
    function handleSettings(req, res) {
      const m = req.headers['x-mode'];        // unrelated value, same name
      if (req.method === 'DELETE' && m) { … }
    }

    GET    /api/live/positions/{param1}/replay  handler=handleReplay    correct
    DELETE /api/live/positions/{param1}/replay  handler=handleSettings  FABRICATED

Wrong in method, handler and line. `m`, `match`, `result` are the ordinary names
here. Two ways the truth was then lost: the fabricated route is VERBED, so
`reconcileDispatchGuardRoutes` kept it and dropped the true verb-less one — the
#2856 `/api/report` shape, through the channel this series added — and `tested`
was name-keyed too, so the tail loop suppressed the real binding's own honest
verb-less emit before reconciliation ever ran.

`matchBindings` and `tested` are now keyed on (enclosing function, name).
`enclosingFunction` is extracted from the walk `enclosingHandlerName` already
did, so there is one function-boundary mechanism, not two. A second declarator
for a key refuses it, and an assignment refuses the name in its own scope and
every enclosing one. `buildRegexConstantMap` refuses a name rebound to anything
that is not a regex literal, closing `let RE = /…/; RE = buildDynamic(req)` and
the `new RegExp(prefix + '/x')` twin.

A use resolves only within its own function. Resolving outward would need a
complete declaration model — params, imports, catch bindings — and a miss there
fabricates exactly the route this fixes. Declining costs the verb, not the path.

THE TERNARY TOOK FIRST-MATCH WHERE THE ALGEBRA IS INTERSECTION. The docblock
proves `c ? A : false ≡ c && A` and says "both hold, so search both", but
`firstNonEmpty` returned one operand's set unintersected:

    (req.method === 'GET' || req.method === 'POST')
      ? (req.method === 'POST' || req.method === 'PUT')
      : false                                    emitted GET and POST
                                                 only POST is reachable
    req.method === 'GET' ? req.method === 'POST' : false
                                                 emitted GET, unsatisfiable

`intersectVerbs` replaces it for both conjunction shapes. An empty side still
yields to the other — "names no method" is not "admits none", which is what the
`isAdmin && POST` fallthrough is for — but two non-empty sides intersect, and an
empty intersection is an unsatisfiable guard that yields no verb.

Both changes strictly REMOVE routes, so SCHEMA_BUMP 58 -> 59: routes are
parse-time output replayed verbatim from a warm cache, and without the bump an
indexed repo keeps serving the fabricated verbed route while the fix looks
implemented.

10 tests added, 9 of which fail without the change. All 86 existing assertions
pass unchanged; none was weakened.

* fix(scope-resolution): bind a type parameter only inside the scope it opened

W2-8 captured `@declaration.type-parameters` on EVERY `type_alias_declaration`,
but an alias becomes a SCOPE only when its value is an `object_type`
(`typescript/query.ts:149`). For a union, array, conditional, mapped, tuple or
function alias there is no scope, so the def — now carrying `typeParameters` —
attached to the innermost enclosing scope, which is the MODULE. And
`typeParameterNamesInScope` folds each scope's set from its PARENT'S, so the
name landed in every scope in the file. The `USES` guard then deleted every edge
whose target had that simple name:

    export interface Result { ok: boolean }
    export type Maybe<Result> = Result | null      // one ordinary line
    export function readResult(r: Result) { … }    // its USES edge is DELETED

Silent data loss, in the edge class whose whole purpose is answering "what
breaks if I remove this field?". Measured: adding two scope-less generic aliases
emptied the fixture of USES edges entirely.

The existing fixture could not see it — it wrote `type Box<Result> = { held: Result }`,
the ONE alias form that opens a scope.

`typeParameterNamesInScope` now reads a def's `typeParameters` only when that
declaration OPENED the scope owning it: `scope.kind !== 'Module'` and the def-id
position equals the scope range start, via the canonical `definitionIdPosition`
rather than slicing the id. That is the same alignment test `pickCallerCallableDef`
uses to tell a closure from a nested function, and it is language-neutral — it
also covers `function f() { type W<Result> = Result[] }`, which a module-scope-only
stopgap would miss.

Every language populating the capture was audited (ts, java, csharp, kotlin,
rust, cpp): all anchor it on a declaration that IS a scope node, including C++
where the capture rides `template_declaration` but the anchor is the inner
`class_specifier`. Go uses a separate sidecar. The TypeScript non-object alias
was the only mismatch in the codebase. `query.ts` is untouched.

THE GUARD ALSO SAT AT THE WRONG LAYER, which forced three defects at once. It
keyed on `edgeType === 'USES'` — and `mapReferenceKindToEdgeType` maps THREE
kinds there, `type-reference`, `value-ref` (#2437) and `macro` (#1934) — and,
because `Reference` carries no spelled name, substituted the resolved def's name
via `simpleNameOfDefId`. So `import { Result as ApiResult }` inside
`function unwrap<Result>()` deleted a REAL edge, while a namespace-qualified
target (`Host.Result`) kept a FALSE one, and a positional `@row:col` suffix broke
the last-colon parse outright.

Moved to `lookupForSite`'s `case 'type-reference'` in `resolve-references.ts`,
which has the spelled `site.name` and the reference kind in hand. One line closes
all three, deletes `simpleNameOfDefId` — a byte-identical duplicate of
`simpleNameOfGraphId` — and removes the only `graph-bridge/` -> `scope/` import
in that directory.

Honest scope: all three sub-defects are real in the code but none is observable
end-to-end today (`value-ref` never reaches this path; TypeScript emits no
cross-file USES for a type annotation at all — a separate pre-existing gap). Those
arms are labelled forward guards in the test rather than claimed as repros.

Fixture grows 1 file -> 4; 3 of 9 assertions fail without the change. The
scope-capture TypeScript fingerprint moves for FIXTURE-CORPUS GROWTH ONLY, with
per-file accounting that sums to the delta and JavaScript unchanged as the
control — see the `_rebaselined_` key.

* fix(scope-resolution): refuse an ambiguous formal, stop the walk at the nearest binding

Two ways W2-2 typed a parameter from the wrong caller, both at the PRECISE 0.9
tier — above every `minConfidence` floor, so nothing downstream can filter them.

`formals` WAS LAST-WRITE-WINS. The key is (filePath, ownerName, parameterIndex),
`ownerName` is a bare identifier, and `emitFormalFacts` emits one site per
parameter of EVERY function collected, nested functions and class methods
included. A plain `.set` let two same-named callables in one file collide — a
free `parse` and a nested `parse`, a free `apply` and `Runner.apply` — so the
last one visited won, fabricating an edge on the loser and leaving the genuine
consumer untyped. The file's own comment covers only the cross-FILE axis.

The correct shape was thirty lines below, in the `producers` map, which does
`producers.delete(cell); conflicted.add(cell)`. `formals` now refuses the same
way: a key claimed by two DIFFERENT parameters is deleted and recorded, so a
third same-named formal cannot re-claim it. Re-stating the same cell is not a
disagreement, so a benign duplicate capture cannot poison a real key.

THE SCOPE WALK CLIMBED PAST A NEARER BINDING. The docblock claimed it stops at
the first scope carrying the name, but it consulted only `parameterProducers` —
a shadowing `const`, a catch binding or an arrow parameter is not in that map, so
the walk went straight past it to the enclosing formal:

    function readSpike(spike) { … items.map((spike) => spike.wickRatio) … }

typed the ARRAY ELEMENT from the outer parameter. `parameterProducerFor` now
stops at the first scope that binds the name AT ALL — reading the scope's own
tables, the same channels and the same reasoning as the sibling
`isNamespaceNameShadowed` — and then stops at a Function boundary. That boundary
is what covers the anonymous arrow: `collectFunctions` drops a callable it cannot
name, so an anonymous arrow emits no formal site and its scope looks empty while
in fact rebinding the name. The cost — a closure genuinely reading an enclosing
parameter now declines — is documented as the deliberate trade.

No cycle guard, deliberately and with the reason stated: both constructions of
`indexes.scopeTree` validate through `buildScopeTree`, which enforces strict
parent-contains-child ranges, so a cycle needs a scope strictly containing
itself. A per-site Set on every read/write site in the repo would defend against
a state the builder rejects.

5 fixtures, 5 assertions; 4 fail without the change and the control passes both
ways. Still uncovered and not faked: a `for (const x of …)` binder shadow — the
binder lives in the loop header, so JS emits no scope to stop at and no Function
boundary intervenes.

* fix(analyze): measure one population in every config, split the stamp on the verdict

`1b41c9df6` fixed the collapse check for the STREAMED configuration by giving
the sink a `structuralRows` subtotal. It does not cover the other one.

`resolveStreamGraphEmit` and `resolveStreamPdgEmit` both open with a
`force === true` gate, so a run without `--force` streams nothing: there is no
manifest, `structuralRows ?? 0` contributes 0, and
`scope-resolution/pipeline/run.ts:1222` (`input.pdgEmitSink ?? graph`) writes PDG
into the ordinary in-memory graph, where `relationshipCount` counts it. And
`isIncremental` requires an existing meta, so a FIRST run is a full write and the
check runs. A first-time `gitnexus analyze --pdg` on a fresh repo therefore
compared structural+PDG against structural and exited non-zero with
"Repository indexed INCOMPLETELY" on a healthy index.

MEASURED, not assumed — `runScopeResolution({ pdg: true })` with no sink:

    pdgEmitSink        = absent (non-force shape)
    relationshipCount  = 1
    residentPdgInGraph = 1
    byType             = [["CFG",1]]

The prior `residentPdgInGraph=0` was taken on a `--force` run, where
`input.graph` IS the sink; it never spoke to this case. `graph-collapse-wiring.test.ts`
had pinned the gap, asserting a PDG-inclusive in-memory count was a valid
structural expectation.

`countStructuralRelationships(graph)` filters `PDG_EDGE_TYPES` over
`forEachRelationshipFields` — the same predicate the sink uses for
`structuralRows` and the adapter for `structuralEdges` — so all three terms
measure one population in every configuration. Declining whenever
`pdg && !streaming` was rejected: that is the DEFAULT PDG shape, so the guard
would be off for every non-force run including the only full write most users
ever do. An unscannable graph (mocked pipelines) yields NaN, the same fact the
old `undefined + rows` produced and one `detectGraphWriteCollapse` already
documents as expected input.

THE THREE-WAY STAMP WAS A TWO-WAY. The comment enumerated collapse -> stamp,
healthy -> clear, no verdict -> carry forward, but the code split on the WRITE
MODE. `graphWriteCollapsed` is undefined for two different reasons, and one of
them is "the structural query threw" — so on a full run where the count could
not be READ, the code took "healthy, clear it" and erased a stamp recording real
edge loss. Run 3 then printed "Already up to date" forever: the exact failure the
comment says it fixed, reachable through the new code's own `catch {}`.

`detectGraphWriteCollapse` now returns `'collapsed' | 'healthy' | 'unmeasurable'`
with a reason, and `selectPersistedCollapseStamp` is a pure exported function
production calls. Two boundaries worth naming: `expected === 0` is unmeasurable
(its own docstring calls it "could not report a total"), but the small-repo
exemption and a cleared ratio are HEALTHY — both counts were taken. Making the
exemption a non-verdict would leave a stamp unclearable on any repo that shrank
below 100 edges, relocating the wedge rather than fixing it.

`getLbugStats` now reports `structuralEdgesError` and warns, and `run-analyze`
falls back to `stats.edges` only when the run had no PDG layer, where the two are
equal by construction. With `--pdg` on there is no substitute, so the absence
becomes an explicit unmeasurable verdict — which preserves the stamp.

13 tests added; 8 fail without the change. The integration suite now seeds a CFG
row and asserts `edges` moves while `structuralEdges` does not — the exclusion
filter was previously unexercised, its own comment conceding "structural == total
here".

* fix(server): check the collapse before publishing the index

W2-6 marked a collapsed run's job `failed`, but the check ran INSIDE
`.then(() => backend.init())` — after the publish. `LocalBackend.init()` is the
publish step: it refreshes the registry and atomically swaps the in-memory repo
map every MCP tool and HTTP route resolves through, and its `validate` pass
prunes only entries whose metadata is provably gone, so it can publish but never
quarantine. The known-incomplete database was therefore live and queryable before
the job was ever marked failed — the job status was a label on a published index,
not a gate. The pre-existing comment two lines above says so outright: "the repo
is actually queryable when the client receives the SSE complete event."

`backend-client.ts` routes `failed` to `onError` and never calls `onComplete`, so
the UI showed an error toast while every query against that repo answered from
the incomplete graph — precisely the confident-wrong-answers failure this guard
exists to prevent.

The collapse branch now returns before publishing; the healthy path publishes via
a nested `backend.init()` so the trailing `.catch` still converts init failures
into the same message. `closeDbHandle()` runs on both paths — it is eviction, not
publication, and the worker rewrote the DB files regardless of outcome, so
skipping it would leave a stale pre-rewrite handle.

Honest limit, stated in the error string rather than overclaimed: this keeps a
FIRST-TIME analyze unpublished, which is the UI's main flow. On re-analysis of an
already-published repo the existing map entry survives and points at the same
storagePath. A real quarantine needs an un-register hook on `LocalBackend`, which
does not exist today — follow-up.

`'partial'` was considered and rejected on evidence: it is not a status. It is an
embedding-specific detail object in the `updateJob` allowlist; the status union
excludes it. Adding it would make `isTerminalJobStatus` false, so `sse-progress`
never writes a terminal frame and never calls `res.end()` — the stream hangs
open — while `backend-client` falls through to `onMessage` and `api.ts` spins the
full hold-queue timeout. `failed` at least terminates.

The failure branch also now sets `repoName`, which only the success path did.

First tests this file has ever had: 4, of which 2 fail without the change. They
assert the ORDERING, not just the final status, and build the worker message by
calling the production `projectAnalyzeResultForIpc` so a field rename breaks the
test instead of silently disabling the branch.

* fix(processes): count the entry-point cap, and make the disclosure proportionate

W2-3 added a truncation disclosure and then missed the largest ceiling it was
written to report. `findEntryPoints` ends `.slice(0, 200)` and
`entryPointsUnexplored` counted against the POST-slice list, so candidates
201..N were invisible — while the derivation docblock claimed "a new ceiling
added later cannot be forgotten here". An existing one was. On this repo's own
corpus the new counter reads 780 of 980 candidates never ranked in.

`entryPointCandidatesDropped` reports the pre-slice count, folded into
`truncated`, with `ENTRY_POINT_CANDIDATE_LIMIT` extracted and `findEntryPoints`
taking the same optional out-parameter `traceFromEntryPoint` already uses. Its
return contract is unchanged.

THE WARN FIRED ON EVERY RUN. At the shipped defaults — only `maxProcesses` is
overridden — `calleesDropped` fires for any function with 5+ callees and
`tracesDepthCapped` for any chain deeper than 10, so an ungated `logger.warn`
was constant background noise, and a warning that always fires is one nobody
reads. The split is the module's own, from the `ProcessTruncationStats` docblock:
"unexplored entry points mean whole flows are missing, while a depth-capped trace
means a flow is present but shorter than it really is."

So `warn` iff whole flows are absent — candidates dropped, entry points never
traced, or flows dropped at `maxProcesses` — and `debug` for a run truncated only
in depth or breadth. `stats.truncation` still carries all six counters; the
machine-readable channel is unchanged, only the log level moves.
`entryPointCandidatesDropped` stays in the loud set deliberately: it is the only
ceiling that GROWS with repo size, while the other two can only fire while
`maxProcesses` is small enough to bind, so gating on those alone would go silent
on exactly the large repos where 200-of-several-thousand is the thinnest sample.
The message leads with the ratio so the line carries a fact, not an alarm.

THREE COMPARATORS ALLOCATED PER COMPARISON, in the function whose own comment
explains the hoist that removed this shape (`deep_chain` 1233 -> 102 ms).
Measured here: +99 ms once per analyze at 80k functions — small, because `n` is
capped at 200 entry points x a 12-trace budget = 2,400 traces regardless of repo
size. Worth fixing anyway: 23,851 comparisons cost 70,524 joins.

One shared `sortByDepthThenPath` (Schwartzian, key built once per trace) now
serves all three sites, and `rankedByInterest` additionally hoists the `isSink`
test that ran twice per comparison. It also settles a separator inconsistency:
`deduplicateByEndpoints` joined on a SPACE while `traceOrderKey` used NUL, and
node ids embed file paths, so two different traces could produce the same key and
the tiebreak fell back to the insertion order it exists to remove — the same
hazard this series' own `->`-padding fix addresses. Order identity is pinned by a
seeded 200-trace corpus asserting the new sort equals the old one exactly.

11 tests added, 9 failing without the change, including two end-to-end
insertion-order arms. The W2-5 determinism block is unregressed.

* fix(docs): restore the agent guidance, and put it in the generator that deleted it

Commit `9e602aef0` — whose message is entirely about the fetch capture — also
regenerated the machine-managed `<!-- gitnexus:start -->` block from a local
non-`--pdg` index, deleting from both AGENTS.md and CLAUDE.md:

  - the whole `MUST treat risk: UNKNOWN as unresolved, not as low` bullet
  - the `pdg_query({mode:"controls"/"flows"})` bullet
  - the `mode: "pdg"` text on the impact bullet
  - `…never read UNKNOWN as an all-clear…` from Never Do

and regressing the stats 248612/565510/918 -> 42853/135955/758. All four document
SHIPPED features: `pdg_query` at `mcp/tools.ts:675`, dispatched at
`local-backend.ts:2233`; `mode: "pdg"` at `tools.ts:448`; `riskNote` at eight
sites.

It matters more than a docs nit because the SAME series makes `UNKNOWN` dominate
a mixed candidate set (`local-backend.ts:6058`) — correct, and it makes UNKNOWN
far more common. The surviving rule only warns on HIGH/CRITICAL, so a set
measuring CRITICAL now reports UNKNOWN and that rule no longer fires, while the
rule that covered the gap was deleted in the same commit range, from all three
files agents actually read.

ROOT CAUSE, which is why restoring the files alone would not have held.
`cli/ai-context.ts` is the template. The `pdg_query` and `mode: "pdg"` text IS in
it, correctly `hasPdg`-gated — a non-PDG analyze SHOULD drop those. The
`risk: UNKNOWN` rules were never in the template at all: they had been hand-added
INSIDE the machine-managed region, so every `gitnexus analyze` on any repo
silently deleted them. This was the second occurrence; #2856's `8f8261021` was
the first. Both lines are now generated unconditionally — they describe impact's
risk semantics, which are not PDG-dependent — so regeneration restores them
instead of removing them.

AGENTS.md and CLAUDE.md are byte-identical to origin/main again, and the fixed
template reproduces that block exactly for `hasPdg: true` plus the real stats.
`.claude/skills/gitnexus-guide/SKILL.md` regains the "Inline staleness signal"
section for a live feature (`local-backend.ts:921`, `:1017-1024`, `:1995`); the
npm mirror's lack of it is pre-existing drift and is left alone, so the new sync
guard is scoped to the canonical and plugin copies.

Guards added, both demonstrated failing against the unrestored files: the managed
block must contain the UNKNOWN policy and its Always-Do/Never-Do bullet counts
must not fall below a floor, and `generateGitNexusContent` must render both lines
for `hasPdg` true AND false while keeping `pdg_query` gated. The existing
fragment lists could never have caught this — they assert presence, and this was
a deletion.

One deliberate loosening, called out rather than buried: the restored text pushes
`ai-context.test.ts`'s block-size ratio past 0.55, so it moves to 0.65. That test
argues against exactly this nudge-the-number pattern. The defence is that the
wording is origin/main's own and the 0.55 budget was calibrated against a block
already missing it; trimming shipped guidance to fit a budget would be the wrong
direction.

* feat(cli): add a bunx lane to the runner ladder

The ladder assumed a Node toolchain: global gitnexus, then pnpm dlx or
npx in some order, with npx as the last resort. On a bun-only machine
npm, npx and pnpm are all absent, so every rung fell through to npx and
both the emitted hint and the generated .gitnexus/run.cjs produced a
command the machine could not run at all.

Add bun as a fourth mode, invoked as an install-free bunx one-shot, on
two rungs:

  - npm 11+ with no pnpm to fall back on — bunx dodges the same arborist
    install crash the pnpm rung exists for (#1939);
  - npm and pnpm both absent — previously the dead end described above.

Every pre-existing outcome is preserved: pnpm still wins on npm 11+, npx
still wins on npm < 11, and pnpm still wins over bunx when npm is absent.
Regression tests pin each of those. The bun PATH probe is lazy, so a
machine with a Node toolchain pays no extra scan and the stale-index hook
budget is unchanged.

bunx takes no allow-build equivalent: bun's --trust is a bun add/install
flag that writes trustedDependencies into a project package.json, which a
one-shot has none of, so the argv stays flag-free.

* fix(lbug): restore the prebuilt native binary when install scripts were skipped

Without this the new bunx lane resolves to a command that still fails:
bun skips lifecycle scripts for a bunx fetch, so @ladybugdb/core's
install script never copies lbugjs.node up from its per-platform
sub-package and every native command dead-ends on 'LadybugDB native
binary (lbugjs.node) is missing'.

The existing guidance cannot rescue that case. It offers pnpm
--allow-build, a global install, or adding trustedDependencies to a
project package.json — bunx has no project package.json to add to, no
per-invocation opt-in, and re-extracts the package on every run, so an
out-of-band repair is wiped before the next invocation. In-process
recovery is the only thing that can work.

Recovery is cheap because nothing is actually absent: the binary is
already on disk in @ladybugdb/core-<platform>-<arch>, and the skipped
script only copied it up. Redo that copy (prebuilt only — never a source
build, never a network fetch) before reporting failure. Best-effort by
construction: read-only node_modules, an absent sub-package or an
unsupported platform all fall through to the existing diagnostics
unchanged, which a test pins.

Also covers pnpm dlx without --allow-build and npm --ignore-scripts.

Declare trustedDependencies so a plain `bun install` in this repo
produces a working native binary too — the remedy the error message
already prescribes.

* fix(ai-context): name every install-free runner in the generated bootstrap note

The emitted gitnexus:start block told a reader with no runner yet to run
`npx gitnexus analyze`, falling back to a global npm install. Both name
binaries a bun-only machine does not have, so the generated AGENTS.md and
CLAUDE.md offered it no reachable bootstrap path.

List npx, bunx and pnpm dlx instead of resolving one. The block is
committed, so emitting the command this machine happens to resolve would
make two contributors on different package managers rewrite it at each
other on every analyze — the per-machine churn #1706 removed. Naming all
three keeps the note machine-independent and correct everywhere.

Regenerates this repo's own committed block to match.

* fix(cli): address PR #2765 review — bunx liveness, restore diagnostics, docs

Addresses all five review comments on #2765.

P1 — `hasBun()` was a PATH-existence check only, so a present-but-broken
`bunx` shim (partial uninstall, failed `bun upgrade`) was selected with no
functional validation. Because selecting `bun` also suppresses the npm-11
npx-crash warning, the result was a silent dead end: no diagnostic, and a
`bunx gitnexus@latest analyze` command that only fails at execution time.
Add `probeRuns()` — a real `bunx --version` liveness probe, gated behind the
cheap spawn-free PATH scan so machines with npm/pnpm still pay nothing. It
ignores the output on purpose (a banner or unparseable version still counts
as alive); only a spawn failure, non-zero exit, or timeout rejects. Injectable
via a new `bunRuns` dep so the mode tests stay host-independent.

P2 — the `gitnexus-cli` skill (and both shipped mirrors) still described the
pre-bunx ladder, stranding exactly this PR's audience: a bun-only machine
whose agent bootstraps from that file was told to use npx/npm/pnpm, none of
which exist there. All three copies now name `bunx` in the ladder and the
bootstrap fallback, with a `shipped-skills-sync` fragment assertion so the
gap is CI-caught (these copies are not byte-compared, only the engineering
family is).

P2 — `restorePrebuiltNativeBinary` collapsed every failure into `false`, so an
EACCES/EROFS from `copyFileSync` was indistinguishable from "no prebuilt
sub-package exists". Users on a read-only `node_modules` layer (a baked
container image mounted read-only — a common CI pattern) got the generic
lifecycle-script advice, which cannot fix a non-writable filesystem. Return a
`RestoreOutcome` instead and route `copy-failed` to its own message.

P2 — document that `trustedDependencies` only takes effect for `bun install` /
`pnpm install` run inside this repo: it does nothing for a `bunx` one-shot or
for a consumer's `bun add gitnexus`. The note sits on
`restorePrebuiltNativeBinary` so a future maintainer cannot mistake that
function for redundant and delete the thing the bunx path actually relies on.

P3 — the `binary_missing` bun advice told `bunx` one-shot users to edit a
package.json they do not have, and listed 1 of the 3 packages this package
now trusts. Both repair messages now share one `BUN_REPAIR_LINES` const with
the full package list and a `bun install -g gitnexus` alternative.

Also: shortened the bootstrap note and raised the CLAUDE.md block budget
2900 -> 2950. The note has to name every install-free runner (that is the
point of the bun lane), and main's own growth since this PR's last green CI
had already pushed the generated block over the old ceiling.

* refactor(cli): simplify the #2765 review fixes

Cleanup pass over the previous commit — no intended behavior change except
the doctor status line noted below.

Reuse: `probeRuns()` duplicated `probeVersion()`'s entire spawn setup — same
argv, timeout, `windowsHide`, and the CVE-2024-27980 Windows-shim workaround —
in a file with two byte-identical committed copies, so the shim rule lived at
four sites. Its docstring's own objection was to the RETURN SHAPE, not to
reuse, so `probeVersion` now returns `{ ran, major, minor }` and `hasBun` reads
`.ran`. Existing callers only read `major`/`minor`, so nothing else changes.

Also dropped a pointless `const runs = () => …` thunk (`&&` already
short-circuits), and deleted a new test that was a character-for-character
duplicate of `falls back to npx when npm is null-absent and pnpm is also
absent` — its cheapest-first-gate rationale moved into that test's comment.

Correctness in the budget comment: the claim that the bun rung is free because
"pnpm is absent there, so its probe never ran" was wrong. `formatAnalyzeCommand`
spawns `pnpm --version` unconditionally when no global `gitnexus` is on PATH —
that spawn IS how pnpm presence is discovered. Real worst case is 5 subprocesses
/ ~8s, and the 8s needs Windows (`shell: true` spawns cmd.exe for an absent
pnpm); on POSIX an absent pnpm ENOENTs in ~1ms. Comment now says that. Likewise
"a machine with npm or pnpm never pays" was wrong for npm 11+ without pnpm —
that IS the rung that pays.

Altitude: `copy-failed` changed only the message text while still returning
`kind: 'binary_missing'`, so `doctor` would have printed "✗ lbugjs.node missing"
directly above a message saying the binary IS present — exactly the
contradiction #2672 removed. Added a `binary_unwritable` kind, a doctor case,
and a `nativeStatusCases` row. The binary-missing message construction moved
out of `checkLbugNative` into `unrestorableBinaryFailure`, typed
`Exclude<RestoreOutcome, 'restored'>` so a new outcome forces a decision
instead of silently inheriting the lifecycle-script advice.

Drift: the trusted-package list was hand-spelled in five places in
native-check.ts, with "matches gitnexus/package.json" asserted only in a
comment. All five now render from one `NATIVE_BUILD_PACKAGES` const (rendered
output is byte-identical), and the test reads the list out of package.json
instead of restating it, so a fourth native package fails the test rather than
silently shipping stale advice.

Finally, replaced the absolute CLAUDE.md block cap with the ratio the two prior
justifications actually appealed to (`< 5465 * 0.55`). Raising 2700 -> 2900 ->
2950 was a ratchet with no ratchet: an absolute cap can only fail on the PR
that adds the character, and the fix is always to nudge the number. Also fixed
a stale runner ladder in skills-steering.test.ts that still omitted bunx.

1c98e7c6dd fix(cli): make .agents/ skill mirror best-effort + exclude from dirty check
Address review findings on PR #2488:

- skill-gen.ts: wrap mirror-root mkdir and per-skill mirror writes in
  try/catch + warn, so a mirror failure (e.g. .agents/skills is a file)
  no longer aborts canonical community-skill generation or destroys prior
  output. Mirroring is now a weak side-flow, matching ai-context.ts.
- git.ts: exclude .agents/ + .agents/** from isWorkingTreeDirty so a
  tracked .agents/ dir doesn't permanently defeat the up-to-date fast path.
- README + --skip-skills help (en/zh): note skills also mirror to
  .agents/skills/ when .agents/ exists, and --skip-skills skips both.

Tests: +18 covering mirror failure paths (root-is-file, per-skill fail,
delete-then-rewrite ordering, namespace-scoped cleanup), dirty-check
excludes (real-edit regression, prefix collision, subdir .agents/,
non-git/git-missing conservative fallback), gate on file-not-dir, and
idempotency.

Tri-review (with Codex as the independent engine) found the CDG 'T'/'F' label
was wrong for the commonest control flow: the M1 TS visitor wires a condition's
fall-through FALSE arm as `seq`/`loop-back`, but `branchSense` mapped both to
'T', so guard clauses, if-no-else, and loop `break` got 'T' instead of 'F' (F1,
P1). The structural CDG edges were correct; only the label — the AC3 "under what
condition does X run?" answer — was wrong.

- F1: replace edge-kind `branchSense` with controller-arm-sense `labelFor`. An
  ambiguous fall-through edge (seq/loop-back) takes the COMPLEMENT of its source
  block's explicit cond-true/cond-false sibling arm. This correctly handles
  do/while (loop-back = TRUE arm) and inner-if-in-loop (loop-back = FALSE arm) —
  the ambiguity a kind→label table cannot resolve. Adds real-parser regression
  tests (the hand-built tests used a fictional cond-false edge and missed it).
- F2: correct the false "sound over-approximation that never drops a real
  dependence" claim in post-dominators.ts — exit-unreachable regions both drop
  and invent control dependences (latent for the current TS visitor, which keeps
  EXIT reverse-reachable). Reframe the exit-less-loop test to characterize, not
  bless, the degenerate behavior.
- F4: make the AC2 property-test reference compute post-dominance INDEPENDENTLY
  (node-removal reachability, no shared code with post-dominators.ts), so a
  post-dom direction bug can no longer pass both the impl and the reference.

* fix(ci): root-prettier format + run-analyze pdg stamp gains maxCdgEdgesPerFunction (#2085)

Two deterministic CI failures from the M5 CDG work:
- quality/format: basicblock-roundtrip.test.ts failed CI's root `prettier --check .`
  (the pre-commit hook uses the gitnexus-local prettier config, which differs);
  reformatted with the root config.
- tests/ubuntu/coverage: run-analyze.test.ts pinned the resolved RepoMeta.pdg
  shape (DEFAULTS) and the all-zero cap override without the new
  maxCdgEdgesPerFunction key (default 5000); added it so resolvePdgConfig
  toEqual and pdgModeMismatch(DEFAULTS) pass. (The stale-test sweep missed this
  file in PR #2188 — same trap M2 hit.)

* feat(mcp): add pdg_query tool definition (controls/flows modes) [M6 #2086]

* feat(mcp): pdg_query backend — controls (CDG) + flows (REACHING_DEF) + e2e test [M6 #2086]

* feat(mcp): document PDG edges + pdg_query (schema, cypher, skill, --pdg-gated ai-context) [M6 #2086]

* fix(mcp): correct pdg_query symbol-anchor lower bound + harden inputs [PR #2188 review]

Tri-review (Codex + adversarial + correctness lanes) of the M6 pdg_query
surface found the symbol-anchor window over-includes a neighbor function's
block. The upper bound was widened to the 1-based BasicBlock basis (symEnd+1)
but the lower bound was left 0-based, so a block on the line directly above the
target function leaked into the result. Shift both bounds +1 ([symStart+1,
symEnd+1]) so the window is the function's true block span.

Also from the same review:
- pdg_query no longer throws on a no-arguments MCP call: the dispatch passes
  raw `params`, so default it to {} → a clean mode-validation error instead of
  a TypeError. (`explain` shares this latent pattern — pre-existing follow-up.)
- tools.ts: the controls-mode description no longer hard-codes the 'F' branch
  sense for guards — `if (!ok) return;` rides the predicate's 'T' arm; the
  guard:true flag is label-agnostic (regex on the dependent block text).

Tests: a hand-seeded adjacency regression (verified failing without the
lower-bound +1) + a no-arguments validation test. Skill doc updated to document
the two-sided [symStart+1, symEnd+1] window.

* fix(mcp): drop always-true anchor conditional in pdg_query [CodeQL #2188]

CodeQL alert 756 flagged `...(anchor ? { anchor } : {})` in _pdgQueryImpl as a
useless conditional: `anchor` is unconditionally assigned in both the file-path
and symbol branches before the return (the not-found/ambiguous/no-layer paths
return earlier), so it is always truthy. Drop `| undefined` from the declaration
(TypeScript definite-assignment holds across both branches) and emit `anchor`
directly.

No runtime change — the `anchor` field was already present on every result.

* test(cli): add hasPdg to the noStats bridge expectation [#2188]

The M6 work threaded `hasPdg: options.pdg === true` into the AIContextOptions
passed to generateAIContextFiles on the --skills regeneration path, but this
test's strict .toEqual expectation predated it (4 keys vs 3 → CI failure). Add
`hasPdg: false` (the value on this non---pdg path). The assertion stays strict;
the #1477 noStats bridging it guards is unchanged.

* refactor(cli): collapse generateGitNexusContent params to an options bag [#2188]

The function had grown to 9 positional params; reaching `hasPdg` meant passing
six `undefined`s (the M6 review's maintainability flag). Collapse params 3-9
(generatedSkills, groupNames, noStats, skipSkills, runnerPath, defaultBranch,
hasPdg) into a `GitNexusContentOptions` object with the defaults moved to
destructuring. The body is unchanged (same local names); the single production
caller and the test calls become self-documenting named fields.

Pure refactor — generated AGENTS.md/CLAUDE.md content is byte-identical.

* fix(cfg): skip CDG for exit-unreachable CFGs (unsound post-dominance) [#2188]

M5 review P2: computePostDominators roots only at cfg.exitIndex and nothing
enforced that EXIT is reachable from every block. For an entry-reachable region
that cannot reach EXIT (a non-terminating loop, or a multi-terminal CFG a future
visitor might emit) the EXIT-rooted reverse walk degenerates — it both drops
real control dependences and invents spurious ones.

Add a pure precondition predicate `isExitReachableFromAllBlocks` (co-located with
the algorithm it guards) and gate it in emitFileCdg: a CFG that violates it is
skipped for CDG (counted as skippedUnsoundFunctions + one onWarn), while its CFG
and REACHING_DEF projections — which do not depend on post-dominance — are kept.
A CDG-specific gate, not a widening of isEmitSafeCfg, so the blast radius is
exactly the unsound CDG. The current TS visitor always satisfies the
precondition (every loop gets a structural header→loopExit edge), so CDG output
for real fixtures is unchanged.

* fix(cfg): bound computeControlDependence materialization (heap parity) [#2188]

M5 review P2: unlike computeReachingDefs (maxFacts) and the emit-side edge cap,
computeControlDependence materialized the full deduped seen/out before
emitFileCdg's per-function cap could trim it — O(edges × post-dom depth) heap
for a deeply nested function.

Add a `maxEdges` ceiling (default 0 = unbounded) returning {edges, truncated},
mirroring computeReachingDefs's {facts, truncated}. The ceiling is checked
before pushing a new unique edge, so `truncated` means a genuine overflow (not
merely "reached cap"). emitFileCdg passes a FIXED materialization ceiling (8× the
default edge cap) — deliberately NOT derived from the runtime edge cap, because
CDG's materialization IS the deduped-edge quantity the cap reports on (deriving
it would pre-truncate that set and lose the exact dropped count). A ceiling hit
is surfaced via onWarn + the truncated flag — never silent.

* refactor(mcp): share resolveBlockAnchor; fix explain's anchor off-by-one [#2188]

M6 review P2 (duplication) + the flagged pre-existing _explainImpl correctness
follow-up. _pdgQueryImpl and _explainImpl each carried a near-identical
symbol↔block anchor resolver that had DRIFTED: pdg_query used the corrected
[symStart+1, symEnd+1] window (BasicBlock startLine is 1-based, the symbol span
0-based) while _explainImpl still used [symStart, symEnd] — dropping a taint
source on the function's final line AND leaking a neighbor's block on the line
directly above.

Extract one `resolveBlockAnchor` helper, used by both, that applies the correct
window and a single (bare) clause convention (callers compose their own WHERE).
This removes ~50 duplicated lines and fixes explain's anchor in one place.

A hand-seeded characterization test (taint-explain Block 4) pins both bounds —
verified to FAIL on the pre-fix window (it returned the line-10 neighbor instead
of the line-15 final-line source). Existing taint-explain + pdg-query suites are
unchanged (their fixtures have interior sources/sinks).

* fix(mcp): pdg_query reports "status unknown" when the layer can't be confirmed [#2188]

M6 review P3 (Codex): when meta is UNREADABLE and the bounded global existence
probe returns zero rows of the edge type, _pdgQueryImpl asserted "no PDG layer"
— but a genuinely edge-free layer (all-linear functions) is indistinguishable
from a missing one via that probe. Soften only that fallback path to an
inconclusive "PDG layer status unknown — was this repo indexed with --pdg?"
note. The meta-stamped path (stamp present, cap absent ⇒ layer truly missing)
keeps the definitive "no PDG layer" wording.

- total/truncated page boundary in both directions (limit below the match count

roots the sibling taint skill uses — .claude/skills/gitnexus/ and the plugin —
so Claude Code + plugin users get it too.

Also extend the gitnexus-guide tool reference (all 3 copies, now byte-identical):
add a `pdg_query` row + a "Control & data dependence" section mirroring the
taint/`explain` section, and reconcile the pre-existing drift where only the
.claude copy carried the `check` tool row (a real registered tool) — all three
now list it.

- "Optional CFG/PDG emission" was M1-only; rewrite to cover the whole opt-in
  stack — M1 CFG, M2 REACHING_DEF, M3/M4 taint, M5 CDG (Ferrante over CHK
  post-dominators, with the exit-unreachable skip), M6 read surface (pdg_query +
  explain, anchored + LIMIT-bounded, shared resolveBlockAnchor) — and note the
  no-Function→BasicBlock-edge join.
- LadybugDB schema notes the `--pdg` additions: the `BasicBlock` node table and
  the CFG/REACHING_DEF/CDG/TAINTED/SANITIZES/TAINT_PATH relation types, kept out
  of the default VALID_RELATION_TYPES / web schema.

fix(mcp): rename query/cypher params so Claude Code can call them (#2186)
* fix(mcp): advertise search_query/statement params for query/cypher tools (#2175)

Claude Code drops a tool-call argument named exactly 'query', making the
query and cypher tools unusable from it. Rename the advertised required
parameters to search_query and statement so the client transmits them.
Handler-side backward-compat for the legacy 'query' key follows in the
next commit.

* fix(mcp): accept search_query/statement with legacy query fallback (#2175)

Resolve the new advertised param names in the backend while still accepting
the legacy 'query' key, so curl/HTTP, other MCP clients, the CLI, the group
path, and the internal executeCypher() all keep working. Alias is normalized
once at the callTool chokepoint (covers group-forward + search alias); query()
and cypher() dual-read defensively. New name wins when both are supplied.
Updates the required-error message and adds dual-accept unit + integration
coverage.

* fix(cli): pass canonical search_query/statement params to query/cypher tools (#2175)

Stop the CLI from depending on the deprecated 'query' alias. No user-facing
change — the positional args are unchanged and the backend accepts both keys.

* fix(mcp): generators advertise search_query in query() examples (#2175)

Update the three doc/example generators (ai-context AGENTS/CLAUDE block,
skill-gen community skills, resources repo hint) so future analyze runs emit
query({search_query: ...}) — the param name Claude Code actually transmits.
Tests assert the new form is present and the legacy query({query: form is
absent (the #2059 generator-test pattern).

* docs(mcp): advertise search_query/statement in skill & guidance examples (#2175)

Sync the committed agent-facing docs to the renamed params so a Claude Code
agent following them emits the transmittable key: AGENTS.md/CLAUDE.md gitnexus
block, the canonical gitnexus/skills/* source and its installed/plugin/cursor
mirrors, and the README examples. Scoped rewrite of the two call prefixes only
(query({query: -> search_query, cypher({query: -> statement).

* style(mcp): prettier line-wrap for #2175 alias-resolution edits

* fix(review): uniform search_query precedence + cypher empty guard (#2175)

Code-review findings (correctness/adversarial/api-contract/maintainability
consensus):
- Group-mode query inverted the 'new name wins' rule: the callTool chokepoint
  backfilled params.query only when empty and the @group-forward read
  params.query directly, so a both-keys (or whitespace-legacy) group call let
  the legacy value win — unlike the local path. Replace the hidden param
  mutation with a self-contained 'search_query ?? query' resolve at the
  group-forward; precedence is now uniformly new-wins at every consumer site.
- cypher() now returns the same friendly required-param error as query() when
  neither statement nor query is supplied, instead of a raw DB prepare error.
- Document the legacy alias as permanent (third-party clients may send query=).
Adds group-forward alias tests (both-keys + legacy-only), empty/whitespace
search_query, the search-alias path, and the cypher empty-statement guard.

* fix(review): non-string alias safety + drop stale chokepoint comment (#2175)

Tri-review findings (correctness/adversarial/security + maintainability):
- Non-string statement/search_query/query (the MCP envelope is not
  schema-validated) hit .trim() and threw TypeError to the server boundary
  instead of a friendly required-param error. Introduce resolveAliasString()
  (new name wins; non-string -> undefined) used by query(), cypher(), and the
  group-forward, so all three return the structured error. Empirically verified
  (123 ?? '' -> 123, (123).trim() throws) — this overrides a critic refutation
  that mis-read ?? as a string coercion.
- Remove the stale query() comment claiming alias resolution happens at a
  callTool chokepoint; that mutation was removed earlier in this PR — each site
  resolves the alias itself.
- Document GroupToolPort.query's intentionally-narrower required type vs the
  wider LocalBackend impl.
Adds non-string and empty-new-key precedence tests.

* fix(mcp): alias falls back to legacy value when new key is blank (#2175)

PR #2186 review finding: resolveAliasString used `canonical ?? legacy`
(nullish), so an explicitly empty/whitespace new-name value (e.g.
{search_query:'', query:'real'}) won and was rejected — discarding a valid
legacy value, contradicting the 'new name wins when both supplied' intent.
Resolve to the first NON-BLANK string instead (new preferred when it carries
a real value, else legacy). Covers query(), cypher(), and the group-forward
(all route through the helper); non-string still resolves to a friendly error.
Flips the presence-based test and adds whitespace/cypher/group fallback cases.

* fix(mcp): drop legacy "query" mention from query/cypher schema descriptions (#2175)

PR #2186 review finding: the search_query/statement inputSchema descriptions
named the legacy "query" key — the exact arg Claude Code drops — and
description text is read by an LLM choosing arguments, weakly nudging it to
send "query". Trim the descriptions to their clean form and move the
legacy-alias note to a code comment next to the schema (preserved for
maintainers / non-CC clients). properties/required unchanged (no `query`).

feat(cli): add .gitnexusrc config and --default-branch for analyze (#243) (#1996)
* feat(cli): add .gitnexusrc config and --default-branch for analyze (#243)

Let a repo preconfigure recurring `gitnexus analyze` options via a
project-local `.gitnexusrc` (JSON) plus a new `--default-branch` flag, so
projects on `develop`/`master` no longer get the generated regression
example rewritten to `base_ref: "main"` on every analyze run.

- New `cli/analyze-config.ts`: locate/parse/validate `.gitnexusrc` (flat +
  nested `analyze` form, alias mapping, fail-closed on unknown keys / bad
  types / hidden chars), merge with CLI (CLI overrides config), and resolve
  the default branch (CLI > config defaultBranch/branch > auto-detected
  origin/HEAD > "main").
- `getDefaultBranch()` in storage/git.ts (best-effort, local-only, no network).
- Thread `defaultBranch` through analyze -> run-analyze -> ai-context so the
  generated regression-compare example uses the configured branch,
  JSON-escaped; the --skills re-generation path uses the same branch.
- `skipContextFiles`/`skipAiContext` alias `skipAgentsMd` (block only, does
  not imply skipSkills); `indexOnly` stays the stronger "skip all injection".
- README + CLI help; unit tests for the config module and end-to-end wiring
  tests that fail if config is parsed but not threaded into analyze/context.

* fix(cli): harden .gitnexusrc against Markdown injection and stale base_ref (#243)

Addresses the tri-review findings on PR #1996.

- P1 (Markdown injection into generated AGENTS.md/CLAUDE.md): reject the
  backtick in validateBranchName (covers --default-branch, .gitnexusrc, and the
  origin/HEAD auto-detect via sanitizeDetectedBranch) and strip it at the
  ai-context sink (markdownSafeBranch); reject Markdown-significant chars
  (` * [ ] < >) in the config `name` (it lands in generated bold/code-spans),
  while still allowing `_ . - /`. Corrected the false "can't break the code
  span" comment.
- P2 (configured defaultBranch silently no-ops on an up-to-date repo): on the
  alreadyUpToDate fast path, surgically refresh only the `base_ref:` line in
  AGENTS.md/CLAUDE.md (refreshBaseRefLine), preserving the rest of the block
  incl. --skills community rows; no-op when unchanged.
- P3: gate the .gitnexusrc key lookup with Object.hasOwn so inherited keys
  (__proto__, constructor, …) hit the actionable "Unknown key" error.
- Cleanups: strip a leading UTF-8 BOM before JSON.parse; give --default-branch
  CLI validation its own `default-branch-invalid` recovery hint; drop the dead
  `options.defaultBranch` write and the now-redundant `options?.` chaining.
- Tests: backtick rejection + even-backtick generated output, 255-char branch
  bound, config `name` Markdown rejection, __proto__ → Unknown key, BOM,
  mergeAnalyzeOptions omits defaultBranch, willGenerateContext suppression, and
  the fast-path base_ref refresh.

* test(hooks): stage resolve-analyze-cmd.cjs for antigravity adapter; harden load checks

The antigravity adapter gained a top-level require('./resolve-analyze-cmd.cjs')
but stageAdapter() did not copy it, so the spawned adapter crashed with
MODULE_NOT_FOUND. Three load-sensitive tests failed; four silent-path tests
false-passed on empty stdout.

Stage the helper alongside the other sibling helpers, and assert status===0 and
no MODULE_NOT_FOUND on the four silent-path tests so a non-loading hook can never
pass green again. Force a deterministic invocation mode in the stale-index test
so the emitted analyze command no longer varies by CI-runner PATH.

* fix(cli): standardize invocation hints on gitnexus@latest; single-source CJS helper

NPX_REF becomes a literal `gitnexus@latest` in resolve-invocation.ts, dropping
the package.json require and the module-load throw (a malformed/absent version
can no longer crash any CLI command at import). The safety this PR delivers is
the install method steered to (global / pnpm dlx), not a pinned gitnexus
version, and the in-repo CJS mirror already degraded to `latest` once copied
outside the package.

Make the two resolve-analyze-cmd.cjs copies byte-identical and add a parity
test that fails on drift. The separate, version-pinned NPX_REF that setup.ts
writes into the MCP server registration is intentional and left unchanged.

* perf(cli): move npm-11 npx warning off module load; memoize invocation mode

warnIfNpm11NpxRisk() ran at index.ts module load, so every CLI invocation
(including the `gitnexus mcp` stdio hot path) paid which/where + npm --version
spawns — against the lazy-startup/MCP-stdout discipline (#207, #1383). Move the
call into analyzeCommand, after the ensureHeap() re-exec guard, so it fires once
in the working process and only for `analyze`.

Memoize the PATH-probe-derived invocation mode (the GITNEXUS_INVOCATION override
stays uncached) so repeated callers don't re-probe, and add a test-only reset so
the cache + once-only warning flag don't leak across the unit suite. Covers the
mode!=='npx', npm<11, and npm-absent suppression branches.

* fix(cli): detect .exe/extensionless global gitnexus shims on Windows

The winGitnexusWrapper branch only matched .cmd/.bat, so a global gitnexus
installed by Volta or scoop (a .exe or an extensionless shim) was missed and the
hint fell back to pnpm/npx. Accept .exe and treat any non-empty `where` hit as
on-PATH (the emitted hint is `gitnexus analyze` regardless of which shim
resolves it). Mirror the change into both resolve-analyze-cmd.cjs copies so the
TS source and the byte-identical hook mirrors stay in sync.

Add Windows-mocked test cases (.exe-only, extensionless, .cmd preference, CRLF
stripping) and register resolve-invocation.test.ts in cross-platform-tests.ts so
the windows-latest runner exercises the branch.

* fix(cli): emit fixed pnpm dlx analyze command in generated AGENTS.md/CLAUDE.md

ai-context baked a machine-resolved command (formatAnalyzeCommand) into
git-tracked AGENTS.md/CLAUDE.md, so the stale-index hint varied per machine and
churned across branches (the #1706 class). Emit the fixed string
`pnpm dlx gitnexus@latest analyze` instead: committed AI-context is the most
authoritative instruction an agent reads, so it must name an install-free,
crash-free method — never `npx`, the npm-11 path #1939 steers away from.

formatAnalyzeCommand stays exported and unit-tested in resolve-invocation.ts
(it still mirrors the two .cjs hook copies); ai-context just no longer calls it.

* refactor(cli): unify hook-helper copy into one non-silent routine

installClaudeCodeHooks copied its four hook helpers in separate try/catch blocks
that silently swallowed failures, while installAntigravityHooks recorded an
error per failed copy. Extract one copyHookHelpers(srcDir, destDir, label,
result) with a single canonical helper list (including resolve-analyze-cmd.cjs)
and the antigravity loop's error-reporting policy, and use it from both paths so
a missing helper surfaces as a setup error instead of a silent runtime crash.

Assert both the Claude and Antigravity install paths co-locate
resolve-analyze-cmd.cjs next to the adapter, and that a failed copy records an
error rather than passing silently.

* test(cli): enforce TS<->CJS invocation parity and guard CLI startup posture

Tier-2 review found two in-scope gaps in the #1945 follow-up:

- The "mirrors resolve-invocation.ts / test enforces parity" comments overclaimed:
  the parity test only compared the two .cjs copies to each other, so the TS
  source and the CJS hook copies could silently drift (NPX_REF, the per-mode
  command, and the Windows shim regex were hand-edited in all three this PR).
  Add TS<->CJS value parity (NPX_REF + formatAnalyzeCommand for every forced
  mode) and a source-level shim-regex parity check, and make the mirror comments
  accurately describe what is enforced.

- No test locked the R3/R4 startup posture, so re-adding warnIfNpm11NpxRisk()
  (or any resolve-invocation import) at index.ts module scope -- the #207/#1383
  lazy-startup regression -- would pass CI. Add a guard asserting index.ts has
  no module-load invocation probe and the warning is wired into analyzeCommand.

* refactor(cli): collapse npx-invocation resolver to one source of truth

PR #1945 carried the gitnexus/pnpm/npx selection in three hand-synced
places — the canonical hook helper, its byte-identical plugin copy, and a
full TypeScript re-implementation in resolve-invocation.ts — kept in lockstep
by per-mode-command and regex-extracted-by-regex parity tests. The TS
formatAnalyzeCommand had no production caller (ai-context emits a fixed
string), and the module memoized + exposed a test-only reset for a "repeated
callers" case that has exactly one caller.

Make hooks/claude/resolve-analyze-cmd.cjs the single source: extract the
Windows-shim line-picking into a pure, exported pickPathMatch() and add an
injectable probe to resolveInvocationMode() so the shipped logic is testable
without spawning or global mocks. resolve-invocation.ts (118 -> 59 lines) now
consumes that cjs via createRequire for resolveInvocationMode/NPX_REF and adds
only the CLI-only npm-version probe and warning; the relative path resolves
identically from src/cli/ (tsx, vitest) and dist/cli/ (shipped, hooks/ is a
published sibling of dist/). Tests exercise the real shipped artifact, the
NPX_REF/mode-command parity scaffolding is dropped (one implementation can't
drift), and parity narrows to the two cjs copies staying byte-identical.

No behavior change: hook stale-index hints and the analyze warning are
byte-identical; the pre-existing setup.ts resolveGitnexusBin is untouched.

The PostToolUse stale-index hint calls formatAnalyzeCommand(), which probes which/where; named PROBE_TIMEOUT_MS=2000 keeps git rev-parse (~3s) + up to two probes well under Claude Code's 10s hook timeout while preserving the machine-correct hint. Byte-identical in the plugin copy.

* fix(cli): steer generated cross-repo group commands off npx (#1939) (U2)

The Cross-Repo Groups block in generated AGENTS.md/CLAUDE.md still emitted bare 'npx gitnexus group ...', funneling npm-11 users into the arborist crash; switch to fixed 'pnpm dlx gitnexus@latest group ...'. Export generateGitNexusContent and add a group-branch test asserting no 'npx gitnexus' literal survives.

* docs: align steering guidance on pnpm dlx gitnexus@latest (U3)

README troubleshooting uses gitnexus@latest; the repo's own committed CLAUDE.md/AGENTS.md stale-index hint now matches the generated output (pnpm dlx gitnexus@latest analyze) so the repo dogfoods the fix.

* test(hooks): assert exact @latest analyze command and pin invocation mode (U4)

Drop dead PKG_VERSION/NPX_REF version-pinned constants; the cjs always emits gitnexus@latest, so assert exact toContain(...) instead of the /@\\S+/ wildcard; pin GITNEXUS_INVOCATION in the --embeddings tests for host-independent determinism.

* test(cli): cover resolver warn/edge branches; document probe seam (U5)

Add coverage for the gitnexus-mode warn suppression, getNpmMajorVersion edge inputs (empty/pre-release/non-numeric), and the Windows non-wrapper pickPathMatch branch; widen the InvocationResolver interface to document the optional probe param.

* fix(cli): lower hook PATH-probe timeout to 1000ms (U1)

In a linked worktree the stale-index hook runs git rev-parse --git-common-dir (~2s) + rev-parse HEAD (~3s) before up to two PATH probes; PROBE_TIMEOUT_MS=1000 holds the worst case near ~7s under Claude Code's 10s hook budget (was 2000, ~1s headroom). Byte-identical in the plugin copy.

* fix(cli): fail closed in gitnexus setup on missing required hook helper/adapter (U2)

copyHookHelpers now returns the failed REQUIRED helpers (the .cjs trio; win-rm-list-json.ps1 stays best-effort since it fails open). Both install paths skip hook registration with an actionable error when a required helper failed; the Claude path also gains the adapter-existence guard the Antigravity path already had. Prevents registering a hook that crashes MODULE_NOT_FOUND on every tool event.

* fix(skills): steer committed skill files off npx to pnpm dlx gitnexus@latest (U3)

All 26 committed skill-file copies (gitnexus/skills, .claude, plugin, cursor) used 'npx gitnexus analyze', contradicting the generated freshness line and funneling npm-11 users into the arborist crash. Replace with 'pnpm dlx gitnexus@latest analyze'; add a regression guard (skills-steering.test.ts) that globs all four locations and fails if any reintroduces it. The cli skill's non-analyze npx subcommands (status/clean/list/wiki) are left as-is (out of the analyze-funnel scope).

Add a load-time guard on the createRequire(resolve-analyze-cmd.cjs) cast so a drifted/renamed cjs export fails loudly at module load instead of as a late TypeError in warnIfNpm11NpxRisk. Add the missing 'group impact' assertion to the ai-context Cross-Repo Groups test, and a resolver-contract test.

* fix(cli): auto-select invocation path with pnpm --allow-build (#1939)

Probe npm/pnpm versions and PATH to pick a working analyze command without
user configuration: global gitnexus first, pnpm dlx with --allow-build on
npm 11+ (Ladybug native scripts), npx on npm 10 and earlier. Update docs,
skills, and tests to match the canonical install-free command.

* fix(cli): place pnpm --allow-build before dlx, repair version-injection seam (#1939)

The auto-selected install command emitted `pnpm dlx --allow-build=… analyze`,
but pnpm < 10.14 keeps `dlx` in its argv escape list, so flags placed *after*
`dlx` are parsed as package specs and rejected (ERR_PNPM_SPEC_NOT_SUPPORTED) on
pnpm 10.2–10.13.x — strictly worse than the bare command. Move the flags before
`dlx` (the position pnpm has honored since 10.2.0) in both byte-identical hook
copies, the committed AGENTS.md / CLAUDE.md, and every skill tree.

Also repairs the CI-red resolveInvocationMode seam: injecting `{ npmMajor: null }`
to simulate an absent npm fell through `??` to the host's real `npm --version`
(npm 10.x on the CI runners → routed 'npx' instead of 'pnpm'). Use an
`'npmMajor' in deps` sentinel so an injected null is honored, drop the dead
parseMajorVersion guard, and gate the flags on pnpm >= 10.2 via a single
minor-aware probeVersion spawn (skipped for committed docs). Align the TS
getNpmMajorVersion timeout to the 1s hook budget and strengthen the
skills-steering guard with a pre-dlx positive assertion plus a post-dlx
regression check.

* docs: add npm-11 pnpm caveat to README Quick Starts (#1939)

The root, package, and cursor-integration README Quick Starts still steered
first-contact users to bare `npx gitnexus analyze` — the exact npm 11.x
arborist install crash issue #1939 names as a funnel. Add a one-line pnpm
`--allow-build … dlx` caveat (keeping the simple npx default for npm<=10 /
pnpm / yarn users); the package README points to its existing npm-11
workaround section.

* docs(skills): route every gitnexus-cli command off npx to pnpm dlx (#1939)

The gitnexus-cli skill demonstrated analyze via `pnpm --allow-build … dlx`
but still showed status/clean/wiki/list via bare `npx gitnexus` — the same
package, the same npm-11 crash-prone install path — and its header claimed
"all commands work via npx". Convert every subcommand to the pnpm form across
all three skill copies and reconcile the header. Broaden the skills-steering
guard to forbid any `npx gitnexus` command in the cli-skill copies.

* perf(hook): probe pnpm once on the stale-index path (#1939)

The stale-index hook resolved pnpm twice — `which pnpm` for mode selection
then `pnpm --version` for the allow-build gate — two spawns for one tool in a
~9s/10s budget. Capture the version once in formatAnalyzeCommand and thread it
through the existing deps seam (a successful `pnpm --version` proves presence),
sharing a memoized PATH probe with resolveInvocationMode. Add explicit pnpm
10.0-suppress / 10.2-emit boundary tests and relabel the unknown-minor case.
Both byte-identical cjs copies updated together.

* fix(setup): single-quote POSIX hook command + assert cliPath patch applied (#1939)

The hook `command` written into editor settings is shell-evaluated; the
double-quoted `node "<path>"` form left `$`, backtick, and other metacharacters
live in an adversarial $HOME. Single-quote the path on POSIX (Windows keeps the
double-quoted form — those chars are illegal in Windows filenames). Also assert
the cliPath source-literal replace() actually matched, recording an actionable
error on drift instead of silently shipping a hook with an unresolved relative
path.

* test(setup): normalize expected hook path for the Windows runner (#1939)

The new POSIX-escaping test built its expected hook path with path.join,
which emits backslashes on the Windows runner, while setup.ts forward-slash-
normalizes the path before quoting — so `expect(cmd).toBe(node '<path>')`
mismatched on tests/windows-latest. Normalize the expected path the same way.
Production code was already correct; only the test's expected value was
platform-fragile.

* fix(cli): steer docs/skills via a project-local runner, not a pnpm default (#1939)

The prior approach hardcoded `pnpm --allow-build=… dlx gitnexus@latest <cmd>`
into every committed skill + the generated AGENTS.md/CLAUDE.md, which assumes
pnpm is installed. Replace it with a CLI-neutral project-local runner:

- `gitnexus analyze` drops `.gitnexus/run.cjs` (a copy of the canonical
  `resolve-analyze-cmd.cjs`, which gains `buildRunnerArgv` + a `require.main`
  exec tail) next to the index. Docs/skills reference `node .gitnexus/run.cjs
  <cmd>`, which auto-selects the runner (global `gitnexus` → `pnpm dlx` → `npx`)
  at call time — no package-manager assumption. README first-run + an inline
  bootstrap note stay universal `npx gitnexus analyze`.
- The exec tail uses `shell` on Windows so `.cmd`/`.ps1`/`.exe` shims resolve
  (execFileSync can't otherwise; Node blocks `.cmd` without a shell,
  CVE-2024-27980), and prints a diagnostic instead of a silent exit 1.

Tests: runner exec-tail (real spawn, exit-code propagation + ENOENT diagnostic),
copy-failure graceful degradation, and per-subcommand routing + pnpm-fallback
vacuity guards. The generated CLAUDE.md block stays under the #856 token budget.

* fix(cli): resolve Windows .cmd version probes so pnpm steering fires (#1939)

probeVersion (and the TS getNpmMajorVersion mirror) spawned npm/pnpm
--version via execFileSync with no shell, so on Windows the .cmd shims
ENOENT'd, the probe reported a present tool as absent, and the stale-index
hook recommended the npx crash path #1939 exists to avoid. Add
shell: process.platform === 'win32' to the version probes (the exec tail
already does this). Parse the first version-shaped line so a Corepack/notice
banner on stdout no longer defeats the parse. Carry pnpm presence separately
from version so a present-but-unparseable pnpm still selects pnpm. Drop the
dead probe ?? resolveOnPath coalesce. Cover resolve-analyze-cmd.cjs (+ plugin
twin) with the shell-injection and windowsHide source-regression guards.

* fix(cli): widen pnpm allow-build for the --embeddings=N equals form (#1945)

buildRunnerArgv detected embeddings via gitnexusArgs.includes('--embeddings'),
which missed the equals form (--embeddings=5000) that Commander also accepts,
dropping --allow-build=onnxruntime-node on pnpm 10.2+. Match both forms.

* test(cli): cover the runner exec-tail Windows shell branch on CI (#1945)

runner-exec-tail.test.ts was POSIX-only and unregistered in
cross-platform-tests.ts, so the run.cjs Windows shell:true exec branch ran on
no platform despite the file comment claiming windows-latest covered it. Add a
.cmd-shim it.skipIf(onPosix) case and register the file in SPAWN_CLI so the
windows-latest job runs it.

* test(hooks): guard resolve-analyze-cmd.cjs in antigravity e2e sanity check (#1945)

The antigravity adapter top-level require()s resolve-analyze-cmd.cjs, but the

surface as noisy MODULE_NOT_FOUND in downstream tests instead of the intended
actionable 'Helper not installed' error. Add it to the loop.

* docs(skills): tie a missing-runner Cannot-find-module error to recovery (#1945)

Generated CLAUDE.md/AGENTS.md make `node .gitnexus/run.cjs` the primary
command, but the runner is gitignored, so a fresh clone or git clean leaves an
agent facing a raw MODULE_NOT_FOUND. The CLAUDE.md block is token-budget-capped
(#856), so the recovery guidance lives in the cli skill (its documented home):
the bootstrap note now names the `Cannot find module` error and points at
`npx gitnexus analyze` to (re)generate the runner.

* refactor(cli): disambiguate the MCP-pinned ref from the @latest hint (#1945)

setup.ts and resolve-analyze-cmd.cjs both exported a constant named NPX_REF
with different values (version-pinned for the persisted MCP entry vs.
gitnexus@latest for hints). Rename setup.ts's module-private constant to
MCP_PINNED_REF (value and behavior unchanged — the MCP pin stays pinned),
leaving the cjs hint ref and its re-export alone. Also route the createRequire
cast through 'unknown' so it reads as an explicit narrowing to the subset this
module uses rather than a claim about the cjs's full export shape.

* fix(cli): apply --no-stats to keep-marker stats line (#1706)

The keep-marker branch of upsertGitNexusSection rebuilt the index-summary
line on every analyze and always re-injected the volatile counts,
ignoring --no-stats. For teams that commit a trimmed AGENTS.md/CLAUDE.md
with a gitnexus:keep marker, that produced recurring no-value merge
conflicts — exactly what --no-stats exists to prevent.

Thread noStats into upsertGitNexusSection. Under --no-stats the keep-path
stats line becomes "Indexed as **<name>**" with no (N symbols, ...)
parenthetical; the project name still refreshes so renames propagate.
The statsPattern parenthetical is now optional so a count-free line left
by a prior --no-stats run still matches.

* test(cli): cover count-return and AGENTS.md parity for --no-stats keep path

Addresses review findings F1 and F2 on PR #1765:

- F1: add a test that counts RETURN when --no-stats is dropped after a
  prior count-free run — guards against the flag becoming sticky.
- F2: extend the noStats+keep "drops the volatile counts" test to assert
  AGENTS.md alongside CLAUDE.md, so a future asymmetry between the two
  upsertGitNexusSection call sites is caught.

fix(cli): make --no-stats actually omit volatile counts (#1477) (#1478)
* fix(cli): make --no-stats actually omit volatile counts (#1477)

Closes #1477.

The `--no-stats` flag on `gitnexus analyze` was advertised as
"Omit volatile file/symbol counts from AGENTS.md and CLAUDE.md"
but had no effect: every reindex still rewrote the markdown with
fresh count phrases, producing chore-commit churn on every run —
the exact problem the flag was added to solve in #704.

Root cause is commander.js negation-flag semantics. `.option(
'--no-stats', ...)` registers the option under the accessor
`stats` (boolean, default `true`; `false` when the flag is passed),
NOT `noStats`. The two action-handler reads in `analyze.ts`
(lines 414 and 500 pre-fix) read `options?.noStats`, which is
always `undefined`, so the `noStats` payload always reached
`runFullAnalysis` / `generateAIContextFiles` as `undefined`/falsy
and the count branch in the template always fired.

Fixed by replacing `options?.noStats` with `options?.stats === false`
at both reads. The strict `=== false` check (rather than
`!options?.stats`) means absent options or absent `.stats` field
fall through as no-stats=false, preserving the documented default-on
behaviour. Also updated the `AnalyzeOptions` interface to declare
`stats?: boolean` (matching commander's actual output) with a
JSDoc explaining the negation, since the prior `noStats?: boolean`
shape was a static-type misrepresentation of what commander
provides at runtime.

Internal call sites that re-pack `{ noStats: ... }` for
downstream consumers (`run-analyze.ts`, `ai-context.ts`) keep
their existing field name — those interfaces are not commander-
shaped, so `noStats` is the correct name there.

## Regression tests

Two new unit tests in `test/unit/ai-context.test.ts`:

* `omits volatile counts when noStats option is set (#1477)` —
  asserts the count parenthetical is absent from both CLAUDE.md
  and AGENTS.md when `noStats: true` is passed.
* `preserves volatile counts when noStats is not set (default)` —
  documents the default-on path so a future refactor can't
  silently flip the default.

Both call `generateAIContextFiles` directly with distinctive numbers
that would unmistakably leak through if the omit branch is broken.

## Manual verification

* `vitest run test/unit/ai-context.test.ts` → 13/13 pass
  (11 prior + 2 new).
* Verified before-fix behaviour by checking out main, running
  `npx gitnexus analyze --no-stats` against an indexed repo, and
  observing the count phrase still present. Re-running on the fix
  branch with the same flag strips the phrase as documented.

* chore(autofix): apply prettier + eslint fixes via /autofix command

* fix(cli): resolve merge conflict markers in analyze.ts (PR #1478)

Remove leftover conflict hunks from main merge; keep commander stats
shape (stats?: boolean), wire noStats: options?.stats === false into
runFullAnalysis and generateAIContextFiles, and retain indexOnly /
skipSkills / skipAgentsMd wiring from main.

feat: gitnexus:keep marker preserves custom context sections (resubmit of #605) (#1508)
* feat: gitnexus:keep marker preserves custom context sections

When <!-- gitnexus:keep --> is present inside the gitnexus block,
analyze only updates the stats line instead of replacing the entire
section with the verbose template. Lets users maintain lean custom
context without it being overwritten on every reindex.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: improve gitnexus:keep marker to reliably preserve custom sections

The `<!-- gitnexus:keep -->` marker inside a GitNexus block tells
`analyze` to only update the stats line (node/edge/flow counts)
while preserving the user's custom layout. This lets teams trim
the verbose default template to a lean format without having it
overwritten on every reindex.

Changes:
- Broaden stats-line regex to match both "Indexed as" and
  "indexed by GitNexus as" formats
- Improve stats extraction from generated content (prefer
  structured match over greedy parentheses)
- If keep marker is present but no stats line found, preserve
  the section as-is instead of falling through to full replace
- Add tests for keep preservation and no-keep replacement

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: address PR #1508 review findings (F1-F5)

Refactor the keep-marker stats-update path and close the test-coverage
gaps surfaced by the production-readiness review.

## Findings 2 + 3 (high) — fragile extraction → silent corruption

Stop re-extracting `newName` (first `**bold**`) and `newStats` (first
`(...)`, with fallback) from generated content. Both are structurally
fragile:

- F2: newName silently picks the wrong value if the template ever
  emits bold text before the project-name line (no current bug; an
  unstated contract with no enforcement)
- F3: newStats fallback `\(([^)]+)\)` matches `({target: "symbolName",
  direction: "upstream"})` from the Always-Do bullet when
  `noStats: true` suppresses the canonical stats line, silently
  corrupting the stats output

Fix: pass `projectName: string` and `stats: RepoStats` directly into
`upsertGitNexusSection`. Build the stats line from those values. Both
callers in `generateAIContextFiles` already have them in scope.

## Finding 1 (high) — misleading return value

When a keep marker is present but no stats line matches the pattern,
the function previously returned `'updated'` without writing,
producing `CLAUDE.md (updated)` in CLI output for a file that was
not touched. Add a distinct `'preserved'` return variant; CLI now
reports `CLAUDE.md (preserved)` honestly.

## Finding 4 (medium) — unanchored stats regex

`/(?:Indexed as|...) \*\*[^*]+\*\* \([^)]+\)/` could match prose
embedded mid-paragraph in user content (e.g. "you'll see it Indexed
as **Foo** (note: ...)"). Anchor with `^...$` plus the `m` flag so
only standalone stats lines match.

## Finding 5 — test coverage gaps

Seven new tests, each cross-referenced to the review finding:

- keep marker OUTSIDE the GitNexus section has no effect
- AGENTS.md keep path preserves custom layout (parity with CLAUDE.md)
- idempotent: second run produces byte-identical output
- CRLF file with keep marker: stats line updates correctly
- noStats + keep marker: not corrupted by Always-Do tuple text (F3 regression guard)
- returns 'preserved' (not 'updated') when no stats line matches (F1 regression guard)
- project name with markdown punctuation (hyphens/slash/dot) lands intact

All 23 ai-context tests pass; typecheck, prettier, eslint clean.

* docs(ai-context): address PR #1508 review findings on keep-marker path

- Clarify that noStats affects generated template only, not keep-section stats updates
- Fix stats-line regex comment to match behavior (no end anchor; trailing suffix kept)
- Assert '. MCP tools.' survives stats replacement in preserve-custom-section test
- Document LF normalization when rewriting CRLF seed in keep-marker CRLF test

feat(cli): add --skip-skills and --index-only flags to analyze (resubmit of #742) (#1485)
* feat(cli): add --skip-skills and --index-only flags to analyze command

The `installSkills()` call in `generateAIContextFiles()` runs
unconditionally, injecting 6 skill files into `.claude/skills/gitnexus/`
even when `--skip-agents-md` is passed. This is problematic for bulk
indexing operations on read-only mirrors or third-party repos.

Add two new flags:
- `--skip-skills`: suppress standard GitNexus skill file injection
- `--index-only`: pure index mode that suppresses all file injection
  (AGENTS.md, CLAUDE.md, and skills), writing only to `.gitnexus/`

This gives users three levels of control:
- `--skip-agents-md` — suppress only root context files
- `--skip-skills` — suppress only skill injection
- `--index-only` — suppress everything (pure indexing)

Discovery context: while bulk-indexing 176 repos with
`--skip-agents-md`, all 144 indexed repos were contaminated with
`.claude/skills/gitnexus/` files requiring manual cleanup.

* fix(cli): address PR #742 review — gate community skills, drop dangling refs, add tests

Bot review (#742) flagged three issues with the original commit:

1. `--index-only --skills` still wrote community-derived skill files
   to `.claude/skills/generated/`. The `--skills` branch in analyze.ts
   was not gated by `skipAll`, so the "skip all file injection" contract
   was violated. Gate `generateSkillFiles()` with `!skipAll` so
   `--index-only` truly wins over `--skills`.

2. `--skip-skills` without `--skip-agents-md` produced AGENTS.md /
   CLAUDE.md that still referenced `.claude/skills/gitnexus/*/SKILL.md`
   files that were never installed — every agent load incurred 6
   failed reads. Pass `skipSkills` through to `generateGitNexusContent()`
   and omit the standard-skill rows (and the entire `## CLI` heading
   when the table is empty). Community skills, when present via
   `--skills`, are unaffected.

3. No filesystem tests for `skipSkills` / `indexOnly`. Add three
   regression guards to `test/unit/ai-context.test.ts`:
   - `.claude/skills/gitnexus/` is NOT created when skipSkills=true
   - Nothing is written when both skipAgentsMd and skipSkills are true
     (the resolved-flag state from --index-only)
   - AGENTS.md/CLAUDE.md routing table omits standard skill references
     when skipSkills=true, but preserves the load-bearing imperative
     sections (Always Do / Never Do / Resources)

* test(cli): PR 1485 review follow-ups (help text, gate test, --skip-skills docs)

- Assert --skip-skills and --index-only in analyze --help (skip-git-cli.test.ts).

- Export shouldGenerateCommunitySkillFiles; unit-test index-only+skills gate.

- Clarify --skip-skills does not suppress --skills community files; --index-only for full skip.

Address review findings on PR 1485 follow-ups:
- analyze.ts emits a one-line note when both --index-only and --skills
  are set, so users see why a pipeline re-index ran with no skill files
  written.
- index.ts --skills help text now flags the --index-only override.
- shouldGenerateCommunitySkillFiles JSDoc documents the dual role of
  the gate (community skills + AGENTS.md/CLAUDE.md re-generation).
- skip-git-cli.test.ts pins the override-warning surface end-to-end.

fix(cli): only match <!-- gitnexus:* --> markers at section position (#1041) (#1042)
`upsertGitNexusSection` in ai-context.ts uses `indexOf` to locate the
bounds of the GitNexus section in CLAUDE.md / AGENTS.md before
replacement. `indexOf` matches the first occurrence of the marker
anywhere in the file, including inline prose references in backtick-
quoted fragments mid-sentence.

The shipped CLAUDE.md contains exactly such a reference ("See the
`<!-- gitnexus:start --> … <!-- gitnexus:end -->` block in AGENTS.md
for the canonical MCP tools..."). Running `gitnexus analyze` on a
fresh install matches those inline markers as section delimiters and
replaces the prose between them with the full ~100-line injected
block, breaking the backtick and corrupting markdown for every user.

Fix: new private `findSectionMarkerIndex` helper that only matches
markers occupying their own line — preceded by `\n` or start-of-file,
followed by `\n` / `\r` (CRLF files) / end-of-file. `\r` is explicit
so CRLF-terminated sections on Windows (core.autocrlf = true) still
match. The generator always emits markers alone on their line, so
every legitimate section continues to update in place; only inline
prose references now fall through to the append branch, which leaves
existing content untouched.

Two new unit tests:
- #1041 regression — seed CLAUDE.md with the shipped inline prose
  line, run analyze twice, assert inline prose preserved verbatim
  and marker counts stay at 2/2 (1 inline + 1 section-position)
- CRLF handling — seed a CRLF file with inline prose + legitimate
  section, run analyze, assert section replaced in place, inline
  prose preserved, stale stub content removed

No destructive ops, no bypass flags, no new deps. Behaviour change
is strictly narrowing — files that previously updated correctly
still do; files that previously got corrupted now fall through to
the safer append branch.

Closes #1041.

feat: configure eslint with unused import removal (#564)
* feat: configure eslint with unused import removal

Add ESLint v9 (flat config) for code quality:
- eslint-plugin-unused-imports for auto-removing dead imports
- @typescript-eslint for TypeScript-aware linting
- eslint-plugin-react-hooks for React hooks rules
- eslint-config-prettier to avoid formatting conflicts
- lint-staged runs eslint --fix before prettier on .ts/.tsx
- CI lint job added to ci-quality.yml

* refactor: remove unused imports via eslint --fix

Auto-fixed by eslint-plugin-unused-imports. No logic changes.

* chore: add eslint fix commit to .git-blame-ignore-revs

feat: configure prettier with pre-commit hook (#563)
* feat: configure prettier with pre-commit hook integration

Add prettier, lint-staged, and prettier-plugin-tailwindcss at the repo
root with husky pre-commit hook integration. Moves husky from
gitnexus/ to root package.json for reliable hook installation.

- Root package.json with prepare/format/format:check scripts
- .prettierrc with endOfLine:lf and tailwindStylesheet for TW v4
- .prettierignore excluding fixtures, vendor, generated, *.d.ts, *.md
- .gitattributes enforcing LF line endings for Windows consistency
- Pre-commit hook uses direct node_modules/.bin/ paths (no npx)

* style: apply prettier formatting to entire codebase

One-time bulk format. No logic changes.
Use .git-blame-ignore-revs to skip this commit in git blame.

* chore: add .git-blame-ignore-revs for prettier format commit

* perf: pre-commit hook runs only tests related to staged files

Use vitest --related to scope test execution to tests that import
the changed files, instead of running the full suite on every commit.

* perf: remove vitest from pre-commit hook, keep in CI only

Pre-commit now runs lint-staged + tsc only. Tests run in CI
(ci-tests.yml) where they belong — keeps commits fast.

* ci: add prettier format check to quality workflow

PRs will now fail if code isn't formatted with prettier.
