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: close reported graph blind spots in reference resolution, analyze and storage (#2856)
* fix(mcp): report UNKNOWN risk when an upstream impact walk finds no callers

`risk: LOW` asserts "safe to change" — a claim ABOUT callers. An upstream
walk that resolved none has nothing to base it on: the symbol may be
genuinely unused, or reached only through a reference class the index does
not record (a property access on a plain object, a bare-identifier read of a
module-scope const). Seeding LOW from an empty result is the false-safe
signal `anyKnownRisk` already refuses to emit on the ambiguous-candidate
path, and that #2687 removed by making an undetermined impactedCount `null`
rather than `0`.

Zero-caller upstream results now report risk UNKNOWN with a riskNote saying
absence of edges is not evidence of disuse. Downstream is untouched: an
empty downstream walk reports resolved callees, not safety.

* feat(javascript): emit ACCESSES for bare-identifier reads of module-scope consts

A constant read only as a bare identifier — `Math.max(LIMIT, n)`, a default
parameter value, `return LIMIT` — minted no reference site at all, because
JS captured only `@reference.read.member`, which requires a receiver a bare
identifier does not have. So "who uses this constant?", the question behind
every dead-code trim and constants refactor, answered with a confident zero
in both directions.

The rest of the machinery was already in place: `FIELD_KINDS` accepts
`Const`, the scope query already declares it via `@declaration.const`, and
`read` maps to ACCESSES for any resolved target. This adds the missing
capture in VALUE POSITIONS ONLY (call arguments, default-parameter values,
return statements) — a blanket `(identifier)` rule would mint a site for
every token in the file, which is unaffordable at repo scale and would keep
alive the block-local symbols `pruneLocalSymbols` exists to drop.

Cross-file readers are NOT yet covered: the site exists and a call through
the same import statement resolves, but a value-kind def does not link
across the import edge. Recorded as a todo with the investigation.

PARSE_CACHE_VERSION bumped 44 -> 45: this is parse-time capture emission, so
a warm cache replays the pre-change capture set and the new edges never
appear — observed directly, a full `analyze --force` produced a
byte-identical graph until the cache was cleared by hand.

* test(javascript): pin A1/A5 plain-object property acceptance criteria

Fixture plus todo specs for the four shapes plain-object property access has
to answer: object-literal keys indexed as Property nodes, a read through the
holding variable, a property WRITE, and a read through an untyped param.

Records the investigation so the work is resumable: the parse-query pattern
scoped to literals bound to a variable matches correctly (verified against
the raw JAVASCRIPT_QUERIES), but no Property node reaches the graph and
local-symbol-pruner is not the cause — it drops only Const/Variable/Static.
The remaining gate is in the parse worker's node-creation path.

No production code — specs only, so the suite stays green.

* feat(javascript): index object-literal keys of a named object as Property nodes

Idiomatic JS models configuration as an object literal, not a class, but
Property definition nodes existed only for DECLARED CLASS FIELDS. A config
field therefore had no symbol at all: `context({name: 'exitMinAtrMult'})`
answered "not found" for a field read and written throughout a live code
path, and ACCESSES had no target to point at.

Both halves are added for keys of a literal BOUND TO A VARIABLE — the parse
query mints the graph node, the scope query mints the def the resolver can
aim at. Unbound literals are deliberately excluded: an inline call argument
or a JSX prop bag is call-site data, not a named surface other code
references, so a node per key there would add volume without adding an
answerable question.

This lands the definition-node half only. The ACCESSES edges still require
receiver resolution — typing the const that holds the literal to the
literal's scope for the precise case, and name-based matching at reduced
confidence for the untyped-param (option bag) case. Both are recorded as
todos with the mechanism each needs.

Also records a trap that cost a wrong conclusion: under vitest the parse
worker runs the BUILT dist code (parse-impl resolves parse-worker.js, absent
under src/, and falls back to dist), so parse-query changes are invisible to
tests until `npm run build`.

* test(cache): move the SCHEMA_BUMP pin to 45

The pin is the guard that makes two branches claiming one cache-schema
number fail loudly instead of silently serving each other's entries, so a
bump is only half-done until the pin moves with it. The bump itself landed
with the JavaScript bare-identifier captures; this is the other half.

Caught by the guard working exactly as designed — the suite failed with
"expected 45 to be 44" rather than letting a mismatched pair through.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* feat(scope-resolution): resolve plain-object property access by unique name

Idiomatic JS reads configuration off an object whose receiver cannot be
typed — an options bag passed as a parameter, a destructured handle, an
imported literal. No precise pass resolves those, so a field read and
written across a live code path produced no ACCESSES edge at all and "who
reads this setting?" answered a confident zero.

A last-resort pass runs after every precise pass and sees only what they
left behind. For each still-unresolved read/write site it asks whether
exactly ONE Property in the workspace carries that name. If so the read
almost certainly means it. If two or more do, nothing is emitted and the
site is COUNTED as ambiguous — a guess between them would be a coin flip,
and a wrong edge in the pre-edit safety gate is worse than a missing one.

Uniqueness is the right gate because it recovers exactly the names worth
recovering: distinctive domain fields (exitMinAtrMult, bookNotionalUsdt)
are unique in a repo and resolve, while generic keys (id, name, data) are
not and are skipped — which is where name matching would over-connect.

Bounded four ways:
- Confidence 0.5, the global tier, with the inference named in the reason,
  so a consumer can filter inferences without losing scope-resolved edges.
- Never second-guesses a precise result: sites already resolved are
  excluded, because first-write-wins stops a duplicate but NOT a second
  edge to a different target.
- Honors `fieldFallbackOnMethodLookup`. A statically-typed language opts
  out of name matching precisely because it over-connects; inferring an
  ACCESSES edge by name is the same claim and must obey the same opt-out.
- Requires an explicit receiver — a bare identifier is not a property
  access, and matching one by name would link a local to an unrelated key.

Indexes graph nodes rather than scope defs because an object-literal key
mints a Property NODE but no scope-resolution DEF: `localDefs` and
`scope.bindings` are both empty for exactly the population this serves.

* feat(analyze): record a collapsed graph write instead of reporting fresh

The dangerous half of a broken refresh: metadata IS written, so the index
reads as fresh, hooks re-arm, and every tool answers from a graph missing
most of its edges — indistinguishable from a codebase that genuinely has no
such relationships. Reported in the field as edges collapsing 23009 -> 2170
and as a CodeRelation table that never materialized.

`analyze` now compares the relationship count the pipeline PRODUCED against
what the DB hands back after the write. Both numbers are already in scope at
the same point, so the shortfall is provable rather than inferred — no
comparison against the previous index, which cannot distinguish a failed
write from a repo that legitimately shrank. A missing relation table needs
no special case: it reads back as a persisted count of zero.

On a collapse the run records `graphWriteCollapsed` in metadata, which
`getIndexIncompleteReasons` turns into `graph-write-collapsed` so status and
the MCP resources report the index INCOMPLETE rather than fresh.

A ratio, not equality: some relationship types do not round-trip one-for-one
and `--pdg` writes MORE rows into the same table, so demanding equality
would fire on healthy runs. Only a collapse is a defect. Fail-safe when the
expected count is unavailable — an implementation that offloads
relationships out of memory may not be able to report a total, and a false
"your index is broken" is worse than a missed one.

* fix(ingestion): qualify object-literal Property ids by their owning object

Two config objects in one file that share a key name generated the same
`Property:<file>:<key>` id and COLLAPSED INTO ONE node, so two distinct
settings became a single symbol. Worse, the merged name then looked
workspace-unique to name inference, which happily resolved reads of it to a
node representing both — a wrong edge in the pre-edit safety gate, which is
precisely what the unique-name pass is bounded to avoid.

`objectLiteralOwnerInfo` already existed for exactly this ("so two
constructors in one file that both define `bar` stay distinct nodes") but
was gated to `Method`. `Property` now opts in.

`findObjectLiteralBindingInfo` returns `ownerName` only when asked. Its
`Method` ids must stay byte-identical — qualifying them would rewrite every
object-literal method id in every indexed repo — while object-literal KEYS,
indexed only since A1/A5, have no such history to preserve.

Found by a test written for the ambiguity path rather than by review: the
suite reported one node where two were expected, and an edge where none
should exist. Both are now pinned, along with the detection boundaries of
the B2 collapse check, which was previously an untestable inline expression
and is now a pure function.

* feat(typescript): index type aliases and shape members as symbols

A TS frontend models its API contracts as `type X = { … }` and `interface`,
so a field on one is exactly what "who breaks if I remove this?" is asked
about. Three gaps made that unanswerable, all in the TypeScript queries:

1. No `type_alias_declaration` -> `@definition.type`, so an alias minted NO
   NODE AT ALL and a context() lookup on an exported contract type answered
   "Symbol not found". TypeScript was the ONLY language missing this — Rust
   (type_item), Kotlin (type_alias), Swift (typealias_declaration) and Dart
   all emit it. The alias was declared for scope resolution but never became
   a graph symbol.
2. No `property_signature` in the parse query, so INTERFACE members minted no
   Property nodes either — the upstream report's "class/interface index fine"
   holds only for the type, not its fields.
3. No `property_signature` in the scope query, so even with nodes present the
   resolver had no member declaration to aim at. Its sibling
   `method_signature` -> `@declaration.method` already existed; only
   properties were missing.

Interface bodies and object-type aliases both spell members as
property_signature, so one pattern per query covers both shapes.

Lands the SYMBOLS, not yet the ACCESSES edges: the shape is already a
class-like scope and now has member declarations, but no edge forms — the
remaining link is owner/type-binding, recorded as todos with the diagnosis.
Note TypeScript sets fieldFallbackOnMethodLookup:false, so unlike JavaScript
there is deliberately no name-based fallback here; the precise path is the
only route by design.

* test(golden): accept interface members in the mini-repo snapshot

Drift is entirely the new TypeScript shape-member indexing: the fixture's
three interfaces (ValidationResult 2, DbRecord 3, LogEntry 3) contribute
exactly 8 Property nodes, each with exactly one HAS_PROPERTY owner edge.

Verified before regenerating rather than after: every pre-existing count is
untouched (CALLS 9, IMPORTS 12, DEFINES 16, HAS_METHOD 1, MEMBER_OF 12,
STEP_IN_PROCESS 12), so nothing was rewired — the digest moved only because
8 edges were added. The fixture's inline `return { valid: false, … }`
literals correctly produced nothing, confirming the object-literal rule
stays scoped to variable-bound literals.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(analyze): never report a collapse from a non-numeric count

The B2 check reported healthy runs as total graph-write collapses. A
non-numeric `expected` (a graph implementation reporting no total, a
lightweight pipeline result) does not skip the guards — it INVERTS them:
`undefined < 100` is false, so the small-repo exemption never fires, and
`0 >= undefined * 0.5` is `0 >= NaN`, also false, so the ratio check
"passes" as well. Both bounds silently evaporate and every such run is
flagged.

That is precisely the failure this check was written to catch, reproduced
inside the check itself: an unmeasurable quantity treated as a measured
zero. Both sides are now validated as finite numbers before any comparison.

`persisted` is also passed as UNKNOWN rather than zero when the DB was not
demonstrably readable: `getLbugStats` flattens "no connection", "query
threw" and "empty table" all into `edges: 0`, so `stats.nodes > 0` is used
as independent evidence the read happened at all.

Caught by the existing run-analyze suites, not by the new unit tests — those
exercised the pure function with well-formed numbers and were blind to the
integration's actual inputs. Both cases are now pinned.

* feat(typescript): make object-type aliases own their members

A TS object-type alias declares the same `property_signature` members as the
interface beside it and answers the same question, but was not a member
owner: its fields were minted with bare ids and no owner edge, so two
aliases in one file sharing a field name collapsed onto one node, while the
identical interface resolved normally.

`type_alias_declaration` joins CLASS_CONTAINER_TYPES (and
CONTAINER_TYPE_TO_LABEL, as that set's invariant requires — a container
missing there gets orphaned member edges or a wrong owner label). Aliases
with no object type (`type Id = string`) declare no members, so they own
nothing and are unaffected.

This also lands the INTERFACE field -> consumer edges, verified on the
mini-repo fixture rather than only on a purpose-built one: `saveToDb` now
links to `ValidationResult.value`, and `formatLogEntry` to `LogEntry.level`
and `LogEntry.message` — three real contract-field reads that previously had
no graph path at all. Golden updated: +3 ACCESSES, no node changes.

The ALIAS field -> consumer edge is still not linked and is recorded as a
todo with the exact blocker: resolving a receiver typed as the alias needs
the NAME to resolve to a class-like def, and `isClassLike` is
Class|Interface|Struct|Record|Enum|Trait. That predicate is read from ~12
sites including MRO and heritage, and every language mints TypeAlias, so
widening it would enrol aliases in linearizations where they do not belong.
Widening only the scope index was tried and reverted — the type-name walkers
gate on it independently, so it fixed nothing and left dead code. That needs
a deliberate "shape-like" concept, not more call-site widening.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* docs(test): record the traced diagnosis for the unlinked alias field edge

Traced to the end rather than left as "needs investigation", so the next
attempt starts from facts:

  1. Graph side is COMPLETE and symmetric with the interface —
     Property:...:LiveModeConfig.bookSlots is owner-qualified and carries
     HAS_PROPERTY.
  2. Resolution DOES reach resolveClassBindingForName('LiveModeConfig')
     (instrumented) and misses.
  3. It misses because the module scope binds LiveModeIface:Interface,
     renderAlias, renderIface — and not LiveModeConfig. The alias has no
     binding on the receiver's scope chain at all.
  4. The TS scope query tags aliases @declaration.type, but normalizeNodeLabel
     accepts only typealias / type_alias and has no "type" case, so it returns
     undefined. Kotlin and Dart use @declaration.type_alias; TypeScript is
     alone on the dead tag.
  5. Retagging is NECESSARY BUT NOT SUFFICIENT — tried, and the binding still
     does not appear, so a second gate exists in how a declaration anchored on
     a node that is ALSO a @scope.class anchor is attached: the alias appears
     to bind inside its own scope rather than hoisting to Module, where
     interface_declaration evidently does hoist.

An isShapeLike predicate (the nominal-vs-structural split: shapes declare
members, nominal types participate in MRO) plus a mirrored
findShapeBindingInScope were built and REVERTED along with the retag. With no
binding on the chain they never fire, and shipping inert widening is worse
than shipping none — the same standard applied to the earlier scope-index
attempt. The design is recorded here; it is worth doing once step 5 is fixed,
and it also unblocks Rust's parked union_item, which the MEMBER_OWNER_NODE_TYPES
comment documents as the same gap in another language.

* feat(scope-resolution): resolve cross-file value references, skip block-locals

Two halves of the same question, "who uses this constant?".

CROSS-FILE. `resolveReferenceSites` runs against the registries and, as its
own comment says, "imports live in finalized bindings the registries can't
see" — which is why free CALLS need `emitFreeCallFallback`. Reads had no
counterpart, so `import { LIMIT }` followed by a bare use resolved to nothing
while a CALL through the very same import statement resolved fine. This adds
the read/write counterpart, reusing `findValueBindingInScope` (which walks the
FINALIZED chain) rather than inventing a lookup. Confidence 0.9: the import
names the def, so this is precise resolution, not inference.

BLOCK-LOCALS. Bare-identifier capture also matches a read of a block-local
`const`, and an edge to one keeps alive exactly the inert locals
`pruneLocalSymbols` exists to drop — a pruned node becomes a retained node
plus an edge, in every function of every indexed repo. Emission now takes the
set of value defs bound at MODULE scope and drops ACCESSES to
Const/Variable/Static outside it. The cross-file pass carries the same
guarantee structurally: a def in another file cannot be a block-local of this
one, so it skips same-file hits entirely.

The block-local leak was already shipped in the intra-file A2 commit and was
found only because a test was written for the guard rather than the feature —
the same way the object-literal id collision surfaced.

Verified on the full resolver matrix: 3172 tests, golden unchanged.

* fix(lbug): diagnose a vanished staging CSV instead of surfacing a Binder error

A forced rebuild could fail with "COPY failed for File: Binder exception: No
file found that matches the pattern .gitnexus/csv/file.csv" and then an ENOENT
on .gitnexus/csv/rel_Folder_File.csv — two engine-level messages that name
neither a cause nor a remedy, which is where several field reports end.

Only tables with rows > 0 enter the COPY manifest (csv-generator.ts), so an
absent file was WRITTEN during this run and removed since. Both COPY loops now
preflight and say exactly that, with the row count, both causes the reports
point at (a second `gitnexus analyze` on the same repo — they share
.gitnexus/csv — or an external cleanup of .gitnexus/), and the action to take.

Scope note, deliberately narrow: this does not attempt to fix WAL corruption
or checkpoint rotation. Those already have detection and recovery hints
(isWalCorruptionError, WAL_RECOVERY_SUGGESTION, the configurable
wal-checkpoint-threshold), and the ~6000 lines added to lbug/ + storage/ since
v1.6.9 — index-lock.ts most of all, which serializes writers and plausibly
closes the concurrent-run class outright — postdate every report in the
window. Guessing at unreproducible durability faults would be speculation;
making the one failure with NO handling legible is not.

An existing overlap test induced this exact scenario (a manifest entry
pointing at a missing csv) and asserted on the engine's wording. Its intent —
that a node-COPY failure is rethrown at the FK barrier rather than swallowed —
is unchanged and still asserted; only the message it matches moved.

* feat(scope-resolution): split shape-like from class-like, linking alias fields

Completes A4: a field on a TypeScript object-type alias now links to the code
that reads it, the last unanswerable half of "who breaks if I remove this?"
for a TS frontend that models contracts as `type X = { … }`.

`isClassLike` answered two questions that only coincide for classes:
  1. does this declare MEMBERS I can look up?   — a SHAPE (structural)
  2. does this participate in inheritance / MRO? — a NOMINAL TYPE
An object-type alias is (1) and emphatically not (2) — it has no supertypes
and no place in a linearization. Widening `isClassLike` to buy (1) would have
enrolled every language's aliases (Rust type_item, Kotlin/Swift/Dart
typealias, C typedef) into MRO and heritage, so the two questions now get two
predicates. Call sites split by which they ask, and their names already said
which: `resolveInheritanceBaseInScope` and `resolveQualifiedInheritanceBase`
keep `isClassLike`; receiver typing and member OWNERSHIP take `isShapeLike`.

Three parts, each necessary and none sufficient alone:
- `findShapeBindingInScope`, mirroring `findValueBindingInScope`'s established
  relationship to `findClassBindingInScope` (same walker, different accepted
  def-type), consulted only AFTER the class lookup misses so a class of the
  same name always wins.
- `populateClassOwnedMembers` uses it, so alias members get an `ownerId` and
  are registered under the alias. Without this the receiver resolved to the
  alias and then found no members under it.
- The TS scope query tags aliases `@declaration.type_alias`, not
  `@declaration.type`: `normalizeNodeLabel` accepts typealias / type_alias and
  has no "type" case, so the old tag mapped to NO label and TypeScript aliases
  produced no scope-resolution def at all. Kotlin and Dart already spelled it
  this way; TypeScript alone was on the dead tag.

An earlier attempt concluded a further "scope-attachment gate" existed. That
was wrong and is worth recording: scope extraction runs in the parse WORKER,
which loads built `dist`, so the retag was never executed. Rebuilt, the alias
hoists to Module scope exactly as the interface does. Same trap as the parse
query — `src` edits to anything the worker runs are invisible until
`npm run build`.

Typedef and Union stay out of `isShapeLike` deliberately: they belong
conceptually (the union_item note on MEMBER_OWNER_NODE_TYPES records the same
gap) but neither is wired as a member container, so including them would widen
a predicate nothing exercises.

Verified on the full resolver matrix: 3173 tests, golden unchanged.

* test(typescript): pin the type-alias capture to a tag that maps to a label

The capture test asserted `@declaration.type`, the tag that
`normalizeNodeLabel` does not recognize (it accepts typealias / type_alias and
has no "type" case). So the test passed for as long as the tag was broken: it
checked only that the capture FIRED, never that it resolved to anything, while
TypeScript aliases produced no scope-resolution def at all.

Updated to the working tag and given a second assertion that the derived kind
string is one the label mapper accepts — the property that actually matters,
and the one whose absence let a dead tag sit pinned.

* fix(lbug): declare TypeAlias member pairs so analyze does not abort

Making object-type aliases member owners emits HAS_PROPERTY from a `TypeAlias`,
and the relation schema declared no such pair. The emit therefore threw
`UndeclaredRelationPairError` and the ENTIRE analyze died on any repo
containing `type X = { ... }` — a hard stop, not a dropped edge. Found by
running the analyzer over a real 16k-node TypeScript repo, not by a test.

`Method` is declared alongside `Property`: a member written
`type Handler = { onClick(): void }` is a method_signature and would fail in
exactly the same way.

Why every existing test missed it: the resolver suites build an in-memory
graph via `runPipelineFromRepo` and never write to LadybugDB, so the schema
constraint was never exercised. `structural-pair-coverage.test.ts` is the one
suite that does run the emitters against the declared pairs — and its own
docstring names the gap: coverage is bounded by NON_BRIDGE_CORPUS, "a new
structural emitter should land with an entry here". This adds that entry,
pinning TypeAlias|Property and Interface|Property as sentinels.

Verified the guard is not vacuous: removing the pair again makes the suite
fail with undeclaredPairs: ["TypeAlias|Property"].

* fix(processes): trace depth-first so multi-hop flows are detected

D1 ("query ranks frontend components above the backend module that owns the
concept") and D2 ("processes is dominated by trivial mechanical chains") are
the same defect, and neither is about ranking or selection.

The walk stops after a fixed NUMBER of traces, so traversal order decides which
traces those are. Breadth-first reaches every shallow terminal before any deep
one, so the quota filled with the shortest paths in the graph and the walk
stopped — `maxTraceDepth: 10` was never approached. Measured on a real repo
before the fix: of 300 processes NONE exceeded 7 steps and 90% were 3-4. A
multi-hop business flow (signal → order → exit) therefore had no process that
could represent it, and `query` could only rank the mechanical pairs that did
exist. Step 4 of the caller already sorts by length and dedupes by endpoint —
it was always asking for the deepest traces this walk could give it.

Depth-first descends to a terminal first, so the same quota is spent on paths
worth keeping. Cost is unchanged: same budget, same cycle guard, same depth
ceiling — only the order differs.

Measured on the same 16k-node repo, same build and flags, BFS vs DFS (an
earlier comparison was discarded as confounded — it crossed builds and --pdg):

  steps   6-8:  50 → 168   (3.4x)
  totals:      844 → 806

and the reported query moved from `LiveSetupView → Cn` (a React component) to
`ReconcilePositions → IsTpInProfit / WithHeld / ShouldNotify` — server-side
exit management, which is what was asked for.

`traceFromEntryPoint` is exported for the test. Traversal order is unobservable
through `processProcesses`: `findEntryPoints` supplies several starting points,
so a deep chain is traced from inside it whatever the order does. A test at
that level passes under BOTH traversals — the first version of this test did
exactly that and guarded nothing. Driving the walk directly, it fails under
breadth-first with "expected 3 to be greater than 3".

* docs(test): correct a stale status note left behind by a later fix

The A1/A5 header still said "edge resolution REMAINING ... neither is
implemented". Both shapes resolve — the typeable receiver precisely, the
untyped one by workspace-unique name — and the tests below assert exactly that,
so the note contradicted the file it sat on.

It was accurate when written and went stale when the work continued past it.
Left as-is it would tell a reviewer that a landed feature is missing.

The TRAP note is kept: the parse worker still runs built dist under vitest, and
that is still the trap it describes.

* feat(scope-resolution): index literals behind identity-preserving wrappers

`export const INERT_EXIT_CONTRACT = Object.freeze({ ... })` minted no
`Property` node for any of its keys. The object-literal rule matches
`variable_declarator > value: (object)` as a DIRECT child, and freezing puts a
call expression in between — so the shape whose fields are most worth querying
was the one shape the rule could not see. Freezing a config object is how JS
publishes an immutable contract, which is why this reads as a confident zero
on exactly the fields a reader cares about.

The allowlist is three functions, not "any call". `Object.freeze`, `seal` and
`preventExtensions` RETURN THE ARGUMENT THEY WERE GIVEN, which is what makes
the literal's keys members of the bound name. For `const x = compute({ a: 1 })`
the literal is an argument and `x` holds compute's return value, so attributing
`a` to `x` would be a fabrication.

Two negative controls, because the obvious one is vacuous: a bare-identifier
callee is rejected structurally and would pass with no allowlist at all, so the
assertion that actually pins the predicate uses `Object.entries` — identical
shape, differing only by name. Verified load-bearing by adding `entries` to the
allowlist and watching that test alone fail.

SCHEMA_BUMP 46 -> 47: parse-time emission, so a warm cache replays the pre-fix
capture set. Observed as a false negative first — `analyze --force` returned
the old node set until the on-disk cache was removed by hand.

* fix(scope-resolution): narrow multi-candidate property names by scope

Workspace uniqueness was the wrong denominator. Measured on the reporting
repo: `exitMinAtrMult` has 26 `Property` definitions — 16 in one-off
`scripts/`, 7 in the frontend, one in a test, and exactly ONE in the backend
that reads it. Every backend read was refused because of competitors the
reader cannot see. The gate was not too permissive or too strict, it was
scope-blind.

A name with several definitions is now narrowed before being abandoned:
same-file first, then files the reading file directly imports, using the
finalized import graph rather than a path-shape heuristic. Exactly one
survivor at the first non-empty tier resolves; anything else stays refused.
A tier holding several candidates stops the walk instead of falling through —
local evidence that is itself ambiguous still contradicts reaching further out.

Confidence stays 0.5 at every tier. Narrowing changes which candidate is
chosen, not the kind of claim: it is still a name match, and the round-1
contract is that filtering on confidence drops all name inference at once.
The reason string now names the tier that fired.

Ambiguity reporting goes from a count to the actual names (capped), because a
count says a gap exists while the names say which fields are unanswerable.

Measured on that repo, backend readers of `exitMinAtrMult` go 0 -> 24 and
total readers 9 -> 45, including the two call sites in
`oppositeSignalExitManager.js` the report singled out. Both narrowing tests
were mutation-checked by dropping the import evidence and confirming they, and
only they, fail.

* feat(scope-resolution): capture destructured parameter keys as property reads

`function exit({ exitMinAtrMult = 0 })` reads that property off whatever the
caller passes, exactly as `cfg.exitMinAtrMult` would. It never appears in a
member_expression, so it had no reference site at all — and this is the shape
the function that IMPLEMENTS a behaviour uses, so the most relevant reader was
the one systematically missing from "who reads this setting?".

Uses a distinct `@reference.read.destructured` anchor rather than
`@reference.read.member`. The latter is filtered emit-side to matches with a
member_expression ancestor, because calls and writes share its shape, and a
destructuring pattern has none — reusing the tag would have been silently
dropped by that filter. The `read.` head already maps to a read kind, so no
mapping change is needed.

Scoped to formal_parameters. A destructuring binding elsewhere
(`const { x } = require('m')`) is frequently an import rather than a field
read, and minting a property read there would attribute module bindings to
unrelated same-named keys.

All three cases (default value, bare shorthand, renamed key) mutation-checked
by removing the patterns and confirming those three tests, and only those,
fail. The renamed case also asserts the edge points at the KEY and that the
local alias mints nothing.

* fix(scope-resolution): link type consumers to the type they name

An exported contract type owned its members after round 1 and still answered
`incoming: {}`, so "what breaks if I remove this field?" — the question a
contract type exists to answer — had no edge to walk. Measured on the
reporting repo: all 324 TypeAlias nodes AND every Interface node had DEFINES
as their only incoming edge.

Two independent causes, and the second is why the first was not enough.

TypeScript captured no type references at all — only cpp and csharp did — so
an annotation naming a declared type minted no reference site. Added for
annotations, generic arguments and `as` assertions, anchored to those contexts
rather than a bare `(type_identifier)`, which would also match the name in
`type X = …` and make every declaration a consumer of itself.

That alone fixed interfaces and left aliases still empty. `TypeAlias` was
missing from `LINKABLE_LABELS`, so alias graph nodes were never indexed in
`nodeLookup` and `resolveDefGraphId` could not bridge a def to its node — the
edge was dropped AFTER a successful lookup. `CLASS_KINDS` has always listed
TypeAlias and the ClassRegistry returned the def correctly, which is what made
this read as a resolution failure; instrumenting the lookup showed it
returning the right def all along and moved the search one table over. Exactly
the bug already documented two entries above it for Trait.

Fixes every language that spells an alias this way — TypeScript, Kotlin, Dart
and Rust all emit `@declaration.type_alias`.

* feat(scope-resolution): capture record construction as property writes

The read side answered well after the narrowing work while "who SETS this
field?" still missed the code that stamps the value. A record built inline —
`return { exitContract: { exitMinAtrMult: settings.x } }` — is bound to no
variable, so it minted no definition and its keys referenced nothing.

Modelled as WRITE REFERENCES, deliberately not definitions. The round-1 rule
already mints Property nodes for literals bound to a variable; minting more for
anonymous records would add same-named competitors to the very name-narrowing
that makes these fields resolvable — measured at 26 competing definitions for
one field on the reporting repo, which is what made every backend read
unanswerable in the first place. A construction site is a USE of a field, not
another declaration of it.

Two positions only: nested under a key, and returned. Both are records with a
name attached (the key, or the function). An inline call argument
(`doThing({ id: 1 })`) stays excluded for the same reason round 1 excluded it
from definitions — it is call-site data, not a named surface — and is asserted
as such.

The enclosing literal is the receiver and it is anonymous, so these route
through the same narrowing and the same refusal-to-guess as every other
untyped receiver.

Verified on the reporting repo: `entryPlan.js` went from no rows to
`selectExitEnvelope` as a writer of `exitMinAtrMult`. Both captures
mutation-checked.

* feat(processes): select round-robin by terminal so the list is not one flow repeated

Ranking was `sort by length` alone, so the top of the list was one behaviour
described many ways: eleven of the top fourteen processes on the reporting
repo were four entry points crossed with three terminals of the SAME
date-window utility cluster. Genuine call chains, but a reader learns one
thing from fourteen entries, and the repo's own domain flows sat below them.

Selection now round-robins across TERMINALS, deepest first. Depth still orders
within a terminal and still leads the list; what changes is that no terminal
takes a second slot until every other has had a first.

Keying on the entry point was tried first and made it worse — many files
declare a `main`, so each was a distinct entry that round-robin then awarded
its own slot, and `Main -> AlignWindowEnd` went from one row to eight. The
repetition was never in where a flow starts.

Measured on that repo: distinct terminals in the top 20 went 3 -> 20, and its
domain flows (`ReconcilePositions -> ...`) moved into the top 4%.

Two things this deliberately does not claim. The reported cause — ranking
rewarding fan-in, promoting chains ending in widely-called helpers — measured
FALSE: those terminals have one caller each (`alignWindowStart` 1,
`validateSymbol` 1). A fan-in discount was implemented against that hypothesis,
measured, and reverted for moving nothing. And a business flow still cannot be
a process in its own right: the walk only emits at a leaf, at max depth, or on
a cycle, so a flow whose meaningful endpoint calls onward survives only as
whatever leaf it bottoms out in. Both are recorded in the code so neither
reads as settled.

* test(structural-pairs): pin the type-annotation USES pair

R2-2 emits USES INTO a `TypeAlias`, so the pair is `Function|TypeAlias` — a
different table from the `TypeAlias|Property` entry added in round 1, and one
that entry stays green without. `TypeAlias` is on the eleven-table list this
suite exists for, and an undeclared pair does not degrade: it throws
`UndeclaredRelationPairError` and kills the entire analyze on any repo
containing an annotated type. Every resolver suite still passes, because they
build an in-memory graph and never write to the DB.

That exact failure shipped once in this PR already. Two emitters into the same
label, each with its own way to reach a released build.

* fix(scope-resolution): build the module-level set before the out-of-core seal

Review blocker. Under `GITNEXUS_DISK_SCOPE_INDEX=1` the seal replaces every
ParsedFile with a scope-STRIPPED copy, and the block-local filter's set was
built after it — so it walked `scopes: []` for every file, came out empty, and
the filter read that as "no def is module-level" and dropped EVERY
`Const`/`Variable`/`Static` ACCESSES edge in the repo. All languages, all
files, including the module-scope-const edges this PR exists to add. Nothing
threw and nothing logged, on the path the largest repos take: the exact
confident-empty answer the PR is about.

Built above the seal now, from `parsedFiles`, and passed as `undefined` rather
than an empty set when no scope was inspectable — an empty set is a legitimate
answer ("this repo has no module-level value defs") and must not be
indistinguishable from "could not look". Fails open; the block-local exclusion
is still asserted under the seal, since that is correctness rather than
optimization.

Also widens module level past `kind === 'Module'`. A `Namespace` scope (TS
`namespace`, Rust `mod`, C++/C# `namespace`) holds importable values too, and
treating its consts as function-locals dropped their reads. Included only when
the whole chain to the root is Module/Namespace, so a namespace declared inside
a function body stays local — asserted both ways.

That fixture then failed for a third reason: `@reference.read.identifier`
existed ONLY in the JavaScript query, so A2 did not work for TypeScript at all.
Added there, and both languages widened to `variable_declarator value:` and
`binary_expression` operands — the gaps review named between what A2 claimed
and what it matched.

Nothing covered `GITNEXUS_DISK_SCOPE_INDEX`. The new parity test asserts the
seal changes no edge, and was verified against an emulation of the original
bug: same-file readers vanish and only the cross-file reader survives.

* fix(typescript): anchor property_signature to declared shapes

Review blocker, and it reproduces end to end. `property_signature` occurs in
EVERY object_type in the TS grammar, not only in an interface body or an
alias's object type, so inline parameter types, inline return types and nested
object types all matched — and the enclosing-container walk hung each one off
the nearest class, interface or alias. Measured against the unanchored rule,
all four appeared as members of shapes that do not have them:

  Property:contracts.ts:Svc.inlineParamOnlyKey
  Property:contracts.ts:Repo.inlineQueryOnlyKey
  Property:contracts.ts:NestedConfig.nestedOnlyKey
  Property:contracts.ts:buildInline.inlineReturnOnlyKey@46:33

When the inline member shares a name with a real one — `run(opts: { retries:
number })` inside a class that declares `retries` — `addNode` is
first-write-wins and the two distinct symbols merge onto one node, so every
context()/impact()/rename() answer about that field describes the merge. The
sibling JS object-literal rule in this same PR is anchored for exactly this
reason; this is the TypeScript half of the same fix.

`(A (B))` matches DIRECT children, so nested object types are excluded by the
same anchor rather than by a second rule.

The first version of these tests was VACUOUS and is recorded here because the
reason generalizes: a collision and a correct exclusion both leave exactly one
node behind, so counting ids cannot distinguish them. Every inline member in
the fixture is now uniquely named, which is the only thing that discriminates —
verified by restoring the unanchored rule and watching exactly those four
assertions fail. A fifth test asserts anchoring costs no real member.

* fix(analyze): correct the numbers feeding the graph-write-collapse guard

Review blocker. The predicate itself held under adversarial probing; every
defect was in what it was handed and what happened after it fired.

(a) `expected` was wrong twice. Under `GraphEmitSink` streaming the bulk types
leave the heap at parse time and never enter `relationshipCount`, so the count
understated the real volume by most of it and the ratio passed trivially —
on `force === true` runs, which include crash recovery AND the
`analyze --force` retry this check's own warning tells the operator to run.
Adds the manifest totals, the same correction the buffer-pool hint in this file
already makes for the same reason. Separately, an incremental run persists only
the changed subgraph while both counts are whole-scope: a 10,000-edge index
that lost 200 replacements reads 9,800 and is certified complete. The check is
skipped on that path rather than answered wrongly.

(b) A throwing edge count became a measured zero. `getLbugStats` initialised
its total to 0 and ran the query in a swallowing catch, so WAL/lock contention
during finalize — documented on this exact call — reported a healthy index as a
total collapse. It now returns `number | undefined`, and the caller requires
both a readable node count and a defined edge count.

(c) A total loss was exempted for being small. The min-edges rule tested
`expected` before looking at `persisted` at all, so `expected = 99,
persisted = 0` — every edge gone — stayed fresh and reported success. Total
loss is now decided first. The existing test asserted the defect; it now
asserts a PARTIAL shortfall, which is the case the exemption was written for.

(d) A detected collapse reported success and exited 0. It is different in kind
from the other incomplete reasons: those describe a run that did what it said
and left work for later, this one means most of your edges are gone and every
query answers a confident empty. The CLI now prints INCOMPLETE with the counts
and sets a non-zero exit code, and the flag crosses IPC so the worker cannot
send a clean `complete` either.

Nothing exercised this wiring — only the pure helper. Adds tests for all four,
each written so the pre-fix arithmetic fails it.

* fix(scope-resolution): keep unique-name property inference inside one language

The pass indexed `Property` nodes from the whole shared graph. Per-language
gating decides whether it RUNS for a language; it never restricted which nodes
could be TARGETS. So the only carrier of a name could be in another language
entirely, and a read here resolved to it on name uniqueness alone — no owner,
no file, no call path.

Reproduced: a Java class declaring `private int loyaltyPointsBalance` and a JS
`cfg.loyaltyPointsBalance` on an untyped parameter produced an ACCESSES edge
from the JS function to the Java private field. Confidence does not mitigate
it, because `minConfidence` defaults to 0 — the tier is only a filter for
consumers who ask for one.

Candidates are now restricted to files in the language's own `parsedFiles`,
which is a precise restriction rather than a heuristic and needs no new node
property.

Every other fixture in the suite is single-language, so this could not be
caught anywhere by construction. The new fixture is deliberately polyglot and
asserts both halves: no cross-language edge, and a same-language unique name
still resolves.

Known and not addressed here: the index is still O(total graph nodes) and is
rebuilt once per qualifying language, the per-language whole-graph-scan pattern
`phase.ts` hoisted out for `sharedNodeLookup`. Hoisting it belongs with that
machinery rather than in this fix.

* fix(processes): explore siblings in source order, log the exhausted budget

`slice(0, maxBranching)` selected the FIRST N callees while `pop()` explored
them LAST-first, so the trace budget went to the last-declared branch. For
`main() { init(); loadConfig(); run(); shutdown(); }` the walk spends itself on
`shutdown` and can drop `init` — the earliest steps of a flow, which is the
opposite of what a process describes. Selecting first-N and exploring last-first
was simply inconsistent; pushing in reverse makes the stack pop in source order.

Measured on the reporting repo, this costs depth: 6-8 step processes go 168 ->
146 of 816. Still roughly three times the pre-PR baseline of 50, and the right
trade — a deep branch is no longer reached by accident of being declared last.

The remaining limit is the BUDGET, not the traversal: with a fixed quota a deep
branch declared after enough shallow ones is not reached at all. That is now
asserted in both directions rather than left implicit, and the walk logs when it
stops with branches unexplored — a silently truncating cap reads as "this is
everything", the same confident-empty answer this work is about, and the repo
already sets that precedent for `dispatchFanoutSkipped`.

Removes the second depth test, which was vacuous: the note twelve lines above
it already said a `processProcesses`-level depth assertion passes under BOTH
traversals, and measured it does — breadth-first yields the same deepest
stepCount of 8, so it passed with the production change reverted. Traversal
order is asserted against `traceFromEntryPoint` directly; what is observable at
the pipeline level is which traces survive selection, which the diversity tests
cover.

Also renames `queue` to `stack` and corrects the BFS references in the module
docstring and the function's own JSDoc, which is what an IDE hover shows.

* fix(impact): carry riskNote onto ambiguous candidates and separate UNKNOWN's two meanings

Two problems on the ambiguous fan-out, which builds its own candidate object
rather than returning the single-symbol shape.

The narrowed type had no `riskNote` field and never read one, so a candidate
that resolved and found no callers reported `risk: UNKNOWN` with nothing
attached — losing the entire point of the change on the path where the reader
has the least context, since the name is ambiguous there by definition.

And `UNKNOWN` used to mean exactly one thing on this path: the probe threw. The
zero-caller branch gives it a second meaning, so an all-UNKNOWN fan-out could
no longer be told apart from a broken one. Candidates now carry `probeFailed`,
and the comment asserting the old reading is corrected.

Also aligns `gitnexus-web`, which review flagged as giving a different verdict
for the same symbol. That surface answers in prose rather than an enum, and its
message said the symbol "appears to be unused (not called by anything)" — the
identical false certainty in words. It now carries the same MEANING rather than
the same field. Downstream wording is unchanged: no outgoing dependencies
really is a fact about the symbol itself.

* test: replace assertions that cannot fail

Four from review, each satisfied by the defect it was meant to catch.

`new Set(props).size === 2` over two different literal strings can only ever
be 2, so it could not detect the node merge its title promises — that is a
difference in COUNT, now asserted on the raw array.

The ambiguity test asserted only an empty edge set, which is satisfied equally
by "the gate fired" and "the name was never looked up". It now also requires
the ambiguity counter to have moved.

`Interface|Property` was listed as a structural-pair sentinel beside
`TypeAlias|Property`, but both its labels are in the SCOPE_BRIDGE cross-product
so the pair is generated by construction and the sentinel cannot fail. Dropped
rather than left reading as coverage; `TypeAlias|Property` is the load-bearing
one.

`TypeAlias|Method` was declared in the schema with no fixture emitting it — a
declared pair no emitter exercises is indistinguishable from a missing one
until an analyze aborts on a real repo. Adds a method-shaped alias member, and
the suite requires sentinels to actually appear, so it is not vacuous.

* docs: document the new incomplete reason, the UNKNOWN verdict and the id churn

Review found the code changes landed without the guidance around them, and an
agent following this repo's own rules would have been told the wrong thing.

`graph-write-collapsed` joined `INDEX_INCOMPLETE_REASONS` with no Sign block
and no recovery section, while the precedent it cites
(`embedding-checkpoint-pending`) has both — so `gitnexus status` would surface a
new string naming silent wrong answers with nothing explaining trigger or
remedy. Added to RUNBOOK and GUARDRAILS, including why this reason alone also
fails the exit code.

`AGENTS.md` said MUST warn on HIGH or CRITICAL and never mentioned UNKNOWN, and
the shipped impact skill's risk table had no UNKNOWN row and still implied
few-callers ⇒ LOW. An agent obeying those rules literally sees `risk: UNKNOWN`
and proceeds, which negates the change the verdict exists to make. Both copies
of both skills updated.

`MIGRATION.md` now records that process ids do not survive this release —
positional ids plus depth-first tracing, source-order siblings and round-robin
selection mean `proc_7_handle` is a different flow afterwards. Bounded honestly:
nothing in-repo joins on a raw process id, so it is index churn, not a broken
consumer.

`ARCHITECTURE.md`'s scope-resolution stage list gains the two new stages.
The guide skill's node list gains `Property` and `TypeAlias` — the two node
types this work most prominently creates.

Also, on the pair-CSV preflight review asked to confirm: the hard abort IS
deliberate, because a fallback recovering zero rows is the confident-empty
failure this work targets. But the transient the message itself names — a second
concurrent analyze sharing `.gitnexus/csv` — is a race, so the check now
re-looks three times over ~150ms before declaring the file gone. Long enough to
ride out a rename, far too short to mask a file that is genuinely missing.

* fix: drop redundant TypeAlias pairs and keep bare identifiers off class members

Two regressions the full suite caught after the review fixes, both real.

`schema-pair-coverage` failed with eleven hand-declared pairs that a rule now
generates. Adding `TypeAlias` to `LINKABLE_LABELS` — needed so
`resolveDefGraphId` can bridge an alias def to its node — also makes it a
SCOPE_BRIDGE source and target, so the cross-product produces `File|TypeAlias`,
`TypeAlias|Property` and nine others that round 1 had declared by hand. Removed;
the invariant is that no pair is both generated and hand-declared.

This also changes what the structural-pair sentinel means, and the comment is
corrected rather than left overstating it: `TypeAlias|Property` is no longer
load-bearing because the label is off the generated grid — it is load-bearing
because it now depends on `TypeAlias` being IN `LINKABLE_LABELS`. Remove it and
the pair stops being generated while the hand declaration is gone, which is the
same state that silently breaks alias consumer edges.

`block-scope-shadowing` failed because a bare identifier resolved to a class
`Property`. `class Box { baseUrl = '...'; pick() { const baseUrl = ...; return
baseUrl; } }` linked the block-local read to `Box.baseUrl`, duplicating the
legitimate `this.baseUrl` edge. A bare identifier is not a member access: with
no receiver there is no object whose property it could be, and in JS/TS a field
read needs `this.`. Receiver-less read/write sites no longer accept `Property`
hits; callables stay reachable, so `cb = save` naming a top-level function is
unaffected.

That defect PREDATES this branch's TypeScript captures — JavaScript has emitted
bare-identifier reads since A2 and no class fixture exercised the shadow. The
TS parity added here is what surfaced it.

Golden snapshot regenerated after verifying the drift line by line: exactly
+5 USES from type annotations in the mini-repo, every pre-existing count
unchanged, so nothing was rewired.

* perf(scope-resolution): share the property-name index across language passes

Review follow-up. `indexPropertyNodesByName` scanned every node in the graph
and was rebuilt inside each qualifying language pass, reintroducing exactly the
pattern `phase.ts` hoisted out for `sharedNodeLookup` — whose comment records
why it matters: "the previous per-language rebuild burned that CPU+heap N times
and, on a huge repo, a tiny language's full-graph copy overlapped the next
language's — a real contributor to the scope-resolution memory peak."

Built once in `phase.ts` beside `sharedNodeLookup` and `sharedFnNodeIndex`, and
threaded through the same `prebuilt*` seam, so tests and isolated calls still
build their own.

Sharing is only safe because the per-language restriction MOVED rather than
disappeared: the shared index is whole-graph, and candidates are filtered to
the language's own files at lookup time. That also fixes a subtlety the
per-language build had backwards — the cap now applies to the FILTERED set, so
a name carried by forty properties across a polyglot monorepo but only two in
the language being resolved is still answerable, where a global cap would have
refused it.

The tri-state at the lookup boundary is deliberate and the three outcomes are
not interchangeable: no property of this name in this language (nothing to say,
and NOT an ambiguity), too many to choose between (reportable), or a list to
narrow.

Caught mid-change by the polyglot fixture: an intermediate state shared the
index without moving the filter, and the cross-language edge came straight
back. That test earning its keep twice is the reason it exists.

* feat(scope-resolution): report when a field's only anchor is another language

Round 3, found OUT-OF-SAMPLE — six field names appearing in no prior report, so
nothing here was tuned against them. All six answered 0 backend ACCESSES while
their definitions sat in `apps/research-dashboard/**`: TypeScript only. The
in-sample set scored 5/5 and the out-of-sample set 0/6, and the gap is entirely
this.

Per-language inference (`3c5eadc7`) is right and stays. What was wrong is that
declining is INVISIBLE: an empty result for a field anchored only in TypeScript
is byte-identical to an empty result for a field nobody reads. One says "look
in the other language or grep"; the other says "delete it". That is the same
confident-empty failure this series exists to remove, one surface over — and
this time the missing fact is about the ANALYZER's reach rather than the code.

Declines are now counted and named, with the languages the anchors actually
live in, kept SEPARATE from ambiguity because the remedies differ: ambiguity
wants better receiver typing, this wants an anchor in the reading language.
Collapsing them would tell a reader the wrong thing to do. A non-zero count
warns at analyze time regardless of dev mode.

The facts are published as `PipelineResult.propertyInference`, which they had
to be for any of this to be testable — and that exposed a second defect. The
round-2 ambiguity assertion, which I told the reviewer of #2856 I had
strengthened, read its stat off a `scopeResolution` field that does not exist
on PipelineResult: the `if (undefined) return` guard swallowed it and the test
passed with the production code deleted. Both that assertion and the new ones
now read the published field, and the guard is an assertion rather than an
escape. Verified by deleting the counter and watching them fail.

Reported by the same round-3 method note that caught it: verifying a fix
against the cases it was written for only proves those cases pass.

* feat(context): explain an empty property result caused by a cross-language anchor

The other half of R3-1. The analyze pass now knows which fields it declined to
link because every definition of the name lives in another language; this puts
that fact where it is actually read.

`context()` on such a field previously returned an incoming list byte-identical
to a genuinely unread field. The two demand opposite actions — "look in the
other language, or grep" versus "delete it" — so the difference has to travel
with the answer:

  unresolved: property reads of this name were NOT linked: every definition of
              it is typescript, and name inference does not cross languages.
              An empty or short incoming list here is not evidence the field is
              unused — confirm with a text search, or give it an anchor in the
              reading language.
  anchorLanguages: ['typescript']

Carried through repo meta because the graph cannot answer it: the unlinked
reads mint no edge and no node, so the only record is the pass that declined
them.

Keyed on the NAME, not on the resolved label. Gating on `=== 'Property'` was
tried first and is wrong — the label reads `''` on this path for a plain
Property node, so the gate silently suppressed the entire feature while every
test still passed. Caught by asserting the field is DEFINED rather than
guarding on it, which is the same anti-pattern that made two earlier
assertions vacuous. The meta list only ever contains property names, so
matching the name is itself the type check.

Cached per (index, indexedAt): `ensureInitialized` deliberately avoids a
per-call `loadMeta` because every tool routes through it, so this re-reads
exactly when a re-analyze could have changed the answer and never otherwise.

* feat(scope-resolution): report declined property reads for opt-out languages too

Generalizing R3-1 rather than waiting for it to be re-reported in the other
direction. The reported case was a JavaScript read whose only anchor was
TypeScript; the mirror — a TypeScript read anchored only in JavaScript — was
still silent, because a language that sets `fieldFallbackOnMethodLookup: false`
had the whole pass skipped, and skipping emission also skipped REPORTING.

Detection is not inference. Counting what could not be linked asserts nothing
about what it means, so `reportOnly` runs the pass for its facts while emitting
no edge, and the opt-out keeps protecting exactly what it protected before.

Two things this turned up that a single-instance fix would have missed:

The cross-language fixture could NOT prove `reportOnly` is load-bearing — the
per-language candidate filter already blocks those edges, so the assertion
passed with the flag forced off. The case that discriminates is a SAME-language
TypeScript read that name inference could legitimately link and the opt-out
forbids; forcing the flag off there emits `readsTsOnly -> tsOnlyBudget`, which
is the violation.

Getting to that case surfaced a sibling gap, recorded but NOT fixed here: the
object-literal `Property` rule is JavaScript-only, so `const CONFIG = { ... }`
in a `.ts` file mints no node and its keys are invisible. The first draft of
this fixture used exactly that shape and could not discriminate for that reason.
It is the TypeScript half of R2-1a and wants its own change, not a rider on
this one.

* feat(typescript): index object-literal keys, as JavaScript already did

The sibling recorded in `0c5a4f64` and deliberately left out of it. Both the
named object-literal rule (A1/A5) and the identity-wrapper rule (R2-1a) lived
only in JAVASCRIPT_QUERIES, so the single most common config idiom in
TypeScript —

    export const tsRuntimeConfig = { tsConfigRetries: 3 };

— minted no node for any key. `context()` answered "Symbol not found" and a
precise read through the holding variable had nothing to resolve to.

TypeScript sets `fieldFallbackOnMethodLookup: false`, so these gain no
name-based inference. What they gain is the PRECISE path, which is the route
TypeScript is meant to use: `tsRuntimeConfig.tsConfigRetries` has a typeable
receiver and now resolves. A read through an untyped receiver stays unresolved
and, since `0c5a4f64`, is reported as such rather than answering an empty set.

Scoped exactly as the JavaScript rules are — bound to a variable, and for the
wrapper only the three functions that return the argument they were given —
with the same `Object.entries` negative control pinning the allowlist.

Found by fixture, not by report: the first draft of the `reportOnly` test used
a TS `const CONFIG = { ... }` as its discriminator and could not discriminate,
because the shape mints nothing. That is the whole argument for sweeping a
class instead of waiting for each instance to be filed.

SCHEMA_BUMP 47 -> 48: parse-time, so a warm cache replays ParsedFiles carrying
none of these matches and the keys stay invisible.

* feat(scope-resolution): anchor anonymous returned object literals to their function

The last gap round 3 named, and the dominant shape in idiomatic JS: 437
`return {` sites in a single backend directory of the reporting repo, including
the ~25-field payload of its entire signal pipeline. The literal binds to
nothing, so its keys could not even be named — "who reads wickRatio?" had no
symbol to ask about.

The enclosing FUNCTION is the owner: the literal is that function's return
shape, a contract its callers consume. Keys qualify as `<function>.<key>`, so
two functions returning the same name stay two shapes rather than one merged
symbol, and multiple returns in one function stay distinct by position.

RECONCILING THIS WITH R2-1b, which deliberately modelled returned keys as WRITES
to avoid adding same-named competitors to narrowing. These are definitions, but
narrowing now ranks DECLARED anchors — named literals, class fields, interface
and alias members — strictly above return shapes. A name that already resolved
keeps resolving to what it resolved to before, so the competitor problem R2-1b
was avoiding cannot come back. Mutation-checked: dropping that ranking breaks
five pre-existing R2 resolutions.

That also required an R2-1b assertion to change, and the change is a
strengthening rather than a concession. It asserted `toHaveLength(1)` — no new
definition — as a proxy for "adding definitions must not move an existing
answer". The proxy is now false while the property still holds, so the property
itself is asserted directly.

No `HAS_PROPERTY` edge from the function: that would be a `Function|Property`
relation pair the schema does not declare, and an undeclared pair does not
degrade — it throws and kills the whole analyze. That already shipped once in
this PR.

Two things found by dumping rather than assuming, both fixed here:

SHORTHAND keys were not matched at all. `return { symbol, interval, score }` is
the commonest spelling and the reporting repo's own payload is mostly this form,
but tree-sitter models it as `shorthand_property_identifier`, which `(pair)`
does not match. Caught by dumping the golden fixture and seeing a literal
returning `{ level, message, timestamp: Date.now() }` had indexed only
`timestamp`. Now covered in return position AND in the variable-bound rule,
which had the same gap.

Provenance was flagged by owner-presence, which mislabelled the anonymous case:
a callback's return shape yields no name to qualify by, so it looked like a
DECLARED anchor and would have outranked real declarations. Flagged by position
now — a different question from whether a name could be derived.

SCHEMA_BUMP 48 -> 49. Within one PR the version only has to differ from main's,
but a build stamped 48 was installed and used to analyze before these captures
existed, so caches stamped 48 carry none of them — the intermediate-build hazard
this ledger already records for 33/34.

Golden regenerated after verifying the drift: exactly +10 Property and +10
DEFINES, every pre-existing count unchanged.

* fix(scope-resolution): rank production anchors above test fixtures

Found by testing R3-4 on the reporting repo instead of on its fixtures. Anchoring
returned literals took `wickRatio` from 6 definitions to 13 — and backend reads
still resolved to nothing, because SEVEN of the new JavaScript anchors compete
and four of them are in `tests/`. A test constructs throwaway shapes carrying
production field names; a read in shipped code cannot mean one of them.

Applied before the declared/return-shape split, because "is this the shipped
program" is the stronger signal — a declaration inside a test fixture is still a
test fixture. Skipped when the READER is itself a test, since a read there
legitimately means the test's own shape.

The first version of this test was vacuous and the mutation check caught it: the
reader sat in the same file as the production anchor, so the same-file tier
resolved it whether or not this tier existed. The reader now lives in a file
that imports neither anchor, which leaves production-vs-test as the only thing
that can decide.

Honest about what this does NOT do: it narrows `wickRatio` from seven candidates
to three, and three functions in different files each returning that field is
GENUINELY ambiguous — refusing is correct, and the ambiguity is now counted and
named rather than silent. The reported question ("who reads wickRatio?") is
answerable only where one producer exists; where several do, the honest answer
is the list of producers, which R3-4 made nameable for the first time.

* feat(scope-resolution): resolve members through a call result's return shape

The question three rounds of reports could not answer, and the one narrowing
must refuse by design: a field produced by SEVERAL functions. A read of
`spike.wickRatio` could mean any producer, so name inference correctly declines
and no amount of tier-tuning changes that. It needs evidence, not inference.

The evidence existed in two halves that had never been joined. The call-result
type binding (`const alert = formatSpikeAlert(row)` binds `alert` to a TypeRef
whose rawName is the callee) predates all of this work; it simply had nothing to
resolve to when the callee returned an anonymous literal, because an anonymous
literal named nothing. R3-4 gave it a name. Joining them:

    const alert = formatSpikeAlert(row);
    alert.wickRatio   ->   Property:...:formatSpikeAlert.wickRatio

Precise, at ordinary emission confidence, and it works EXACTLY where narrowing
cannot: several producers sharing a field name stop being competitors because
the receiver says which one. Runs before the name fallback and claims its sites,
so a precise answer is never second-guessed by a name match.

Measured on the reporting repo: 1,410 precise edges, and all six fields round 3
verified OUT-OF-SAMPLE go from 0 backend readers to 7, 11, 10, 7, 6 and 14.
Round 3 scored 0/6 on that set; this is 6/6.

The bound is asserted, not just documented: a read off a BARE PARAMETER has no
binding here, because typing it needs the caller's type to flow in — that is
inter-procedural and genuinely larger. Those reads still fall through to name
inference and are still reported when it declines. The fixture has two producers
sharing a field name precisely so the test cannot pass by name matching, and
mutation-checking the owner lookup fails it.

No SCHEMA_BUMP: this is scope resolution, not parse-time capture, so a warm
cache already carries everything it reads. Noted in the ledger because the
reflex on this branch has been to bump, and an unnecessary bump costs every user
a full re-parse.

* Revert "return-shape anchoring" (R3-4/R3-5): it degrades query

Reverts af5eec5c, c764847a and 4f93f32e. The capability was real and measured —
all six fields round 3 verified OUT-OF-SAMPLE went from 0 backend readers to
7/11/10/7/6/14, 0/6 to 6/6, via 1,410 precise return-shape edges. It is reverted
anyway, because it costs more than it buys in its current form.

`cli-limit-e2e` caught it. Bisected to af5eec5c: on the mini-repo fixture,
`query('message')` returned two processes before and NONE after. The mechanism
is not window displacement — that hypothesis was tested with a partition that
kept function-local property keys from taking window slots, and it changed
nothing. Indexing the keys of every returned literal adds many nodes whose names
are ordinary words, which moves the BM25 CORPUS statistics: "message" gets less
discriminating, and `createLogEntry` — the callable that actually carries the
processes — stops ranking at all. A corpus-level effect is not repairable by a
tie-break.

Trading a regression in `query`, one of the core tools, for coverage in
`context` is the wrong trade, and shipping it because the number was good would
be the same mistake this PR spent three rounds removing: a confident answer that
is worse than the honest one.

What the work established, and what re-landing needs:

  - The mechanism is right. Joining the existing call-result type binding to a
    named return shape resolves `alert.wickRatio` by EVIDENCE, which is why it
    succeeds exactly where name inference must refuse.
  - The cost is search dilution, and it needs to be measured on BM25 ranking
    BEFORE the capture lands — not discovered by a downstream e2e test.
  - The likely shape of the fix is keeping return-shape keys out of the text
    search corpus while keeping them in the graph, which needs persisted
    provenance rather than the in-memory flag used here.

Kept: everything through 8972d223, which is verified green.

* feat(search): give the index a notion of DETAIL symbols, and re-land R3-4/R3-5

Reverts the revert. The return-shape work was correct and measured — 1,410
precise edges, and all six fields round 3 verified out-of-sample going 0/6 to
6/6 — and it was dropped for a regression that was really a MISSING LAYER: the
search index had no way to say "this symbol is queryable but is not a concept a
text search should surface on its own".

Indexing the keys of anonymous returned literals adds many nodes whose names are
ordinary words (`message`, `value`, `timestamp`). Without that notion they
compete on equal terms in FTS, push the CALLABLES named after the same concept
past the search's row cap, and `query('message')` returned two processes before
and none after.

The layer, rather than a workaround:

  - `Property.isDetail`, persisted. A Property-only column, which that table
    already precedents with `declaredType`, set where the key is minted.
  - `buildFtsQueryCypher` filters on it for the Property table, BEFORE the row
    cap. That placement is the whole point: rows crowded out never reach the
    caller, so no downstream re-ranking can recover them. Two downstream fixes
    were tried first — a tie-break and a partition of the merge window — and
    recovered nothing, which is what located the real seam.
  - `IS NULL`-tolerant, so an index written before the column existed still
    answers instead of returning nothing.

Verified by the A/B that found the regression: the query's result order is now
byte-identical to the pre-R3-4 baseline —
`proc_0_processrequest, proc_2_errormiddleware, Function:createLogEntry,
Property:LogEntry.message` — with the return-shape coverage retained.

The determinism guard then caught prose in the new DDL comment containing the
token this repo scans for, which would have read as an unordered query. Reworded;
that suite is doing exactly its job.

* feat(processes): let a flow end where the program reaches outward

The item three rounds kept circling. A trace was only emitted at a node with NO
outgoing calls, so a real flow — scan, score, arm, PLACE THE ORDER — is always a
PREFIX of some longer chain that runs on into date helpers, and could never be a
process in its own right. Ranking could not fix that; the flow was never a
candidate to rank.

What blocked it was signal granularity, and the fix is the layer that was
missing rather than a heuristic. GitNexus already knew where the program reaches
outward: the parse phase collects fetch calls and ORM queries carrying
`filePath` + `lineNumber`. Those facts only ever produced FILE-level edges
(`File -[FETCHES]-> Route`), which cannot end a trace — every function in a file
containing one would qualify. Attributing each site to the function whose range
CONTAINS it turns the same facts into the function-level signal the walk needs:
no new extraction, no new relation pair, no schema change. Innermost wins, so a
closure that performs the call is the sink rather than the function spanning it.

Three touch points, and the second is the one that makes or breaks it:

  - the walk emits at a sink AND CONTINUES, so `placeOrder` is an endpoint while
    `placeOrder -> formatDate` still exists separately;
  - subset-removal PRESERVES sink-terminated traces. A sink flow is by
    definition a prefix of the chain that runs past it, so emitting one at the
    walk and deleting it one step later would have been a no-op. Mutation-
    checked: removing this preservation fails all three sink tests, including
    the one asserting the sink is reached at all;
  - selection ranks sink-terminated above leaf-terminated, then by depth.

`processes` now declares `parse` as a dependency. It historically avoided that
on the grounds the dependency was spurious for a progress counter — it is no
longer spurious, so it is declared rather than reached for implicitly, and the
read fails open so a pipeline without that output detects no sinks instead of
losing every process.

Bounded honestly: this fires where fetch/ORM extraction fires. On the reporting
repo it will do nothing until route detection handles hand-rolled dispatchers,
since that codebase routes with `pathname === '/api/...'` on raw node:http and
produces zero Route nodes — a separate gap, and the next one worth closing.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* docs(processes): the comment above the sink ranking still described it as unreachable

R3-6 taught the walk what a sink is, but the block explaining the ranking still
carried the paragraph written when that was out of reach — "a business flow
still cannot be a process in its own right ... fixing that means teaching the
walk what a sink is" — sitting directly above the code that does exactly that.
A reader arriving at `rankedByInterest` would take the limitation as current.

The measured-false fan-in finding stays; it is still true and still worth not
re-deriving. What replaces the stale half is the bound that IS current: sinks
fire where fetch/ORM extraction fires, so a codebase whose outward calls are not
detected as such still sees leaf-terminated traces only.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* feat(routes): read a route that is declared by a comparison, not by a framework

`route_map` on the reporting repo returned

    {"routes": [], "total": 0, "message": "No routes found in this project."}

for a codebase with SEVENTEEN route modules, an `apiRouteTable.js`, and 113
path comparisons. Not a partial answer — a statement about the code, and a
false one. Same confident-empty class as the rest of this branch, except here
it takes out a whole tool.

Four route-discovery paths existed — filesystem convention, single-file
framework route, cross-file framework route, decorator — and every one of them
needs a FRAMEWORK to declare the route. A raw `node:http` server declares it
the only way the language offers:

    if (req.method === 'GET' && pathname === '/api/live/portfolio') { … }

A path, a verb, and a handler. Nothing in the pipeline could read it.

The failure modes are not symmetric, so the rules are weighted accordingly: a
route this misses is a coverage limit, a route it invents is `route_map`
asserting something false. A comparison therefore qualifies only against a
demonstrable request path (`pathname`, `*.pathname`, `req.url`; `path` is
excluded — in Node it is overwhelmingly `node:path` or a file location), and
anything untranslatable is dropped rather than approximated:

  - `pathname.startsWith('/api/')` is a namespace test; minting `/api` would
    claim a route nobody serves;
  - a bare `pathname === '/'` with no verb is more often the static-file
    normalisation branch (`pathname === '/' ? '/index.html' : pathname`) than a
    route — WITH a verb the intent is unambiguous, so that form IS taken;
  - an anchored regex converts only when its body is a literal path plus
    single-segment wildcards, so `/^\/api\/research-runs\/[^/]+$/` becomes
    `/api/research-runs/{param1}` while an optional group or an alternation
    bails.

Three things went in that nobody reported, each found by measuring rather than
by a second report.

`switch (pathname) { case '/api/x': }` is the same dispatch in different
syntax, and waiting for a bug report per shape is how a graph stays permanently
one idiom behind the code it indexes.

The reconciliation had to move up a level. The reporting repo keeps its path
table (`isKnownApiPath`) in one module and its handlers in sixteen others, so a
per-file rule sees each half separately and lists every route twice — once
verb-less with the table as its "handler", once properly. Measured: 22 of the
first 94 routes were that shadow. Only the whole registry can tell them apart,
so the rule lives in the routes phase and touches dispatch-guard routes only —
a framework route without a verb is method-agnostic BY DECLARATION (a Django
function view, a Laravel resource), a fact rather than a weaker observation.

And a path composed from a constant needed folding. One of those seventeen
modules writes every one of its routes as `` `${autoTradeBasePath}/rules` ``,
where the base is an alias of a module-level literal. Refusing that lost the
whole file — and lost it INVISIBLY, since a module with unfoldable paths and a
module with no routes are the same empty answer. Same-file only, literals only,
one alias hop, and it refuses on ambiguity: a name declared twice with
different values is dropped rather than guessed, because a partially-folded
path is a wrong route and a wrong route is the failure this module exists to
avoid.

Wiring is a LanguageProvider hook, not a language check in shared code.
`extractDecoratorRoutes` was already the general "route from this file's own
AST" channel rather than a decorator-only one — express routes have flowed
through it as `decorator-express.get` for a while — so the transport, the
`(method, url)` dedup and the handler-symbol resolution all apply unchanged.
`ExtractedDecoratorRoute.source` carries the one thing that genuinely differs:
a decorator route is DECLARED, a dispatch-guard route is INFERRED. The walk is
gated behind a substring pre-filter so it costs nothing on files that cannot
produce a route, and the gate is sound by construction — every rule reaches a
route only through `isPathExpression`, which needs one of exactly those tokens.

SCHEMA_BUMP 49 -> 51, two entries. Decorator routes are worker output carried
in the parse cache, so a warm cache replays results predating the extractor and
`route_map` stays empty — the symptom this fixes, wearing the mask of "the
extractor does not work". The second bump is the v34 hazard tripping again: a
build stamped 50 had already been used to analyze before folding existed, so
caches stamped 50 carry the unfolded route set. Caught by measuring — the
post-folding run came back suspiciously fast and would have reported the
pre-folding number.

* fix(scope-resolution): ask whether a value def is FUNCTION-LOCAL, not whether it is module-level

The locality filter for value references was written as an ALLOWLIST of
module-scope defs, and that shape cannot express a class member. A value def has
three homes, not two: module level, a function body, and a CLASS body. Java and
C# fields and Python class attributes live in the third, so an allowlist keyed on
"module level" excludes every one of them by construction.

The guard written to make that safe could not fire either. The set arms whenever
a Module scope is FOUND, and Java has module scopes while having no module-level
values at all — so for Java it armed permanently empty, which is exactly the
state the guard exists to distinguish from "there genuinely are none".

Inverting it removes the class. A blocklist of defs positively identified as
function-local fails safe: a Java field, a Python class attribute, or a language
whose scopes could not be inspected is emitted rather than dropped. That also
retires the arming flag — an empty blocklist and an uninspected one mean the same
thing, and both mean "emit". The failure mode moves from "silently deletes an
edge class" to "retains an inert local", which is the right direction for a tool
whose stated principle is that a confident empty answer is the worst outcome.

MEASURED, because the review that prompted this reported it as a P0 deleting
every Java/C#/Python field ACCESSES edge, and that half does not reproduce.
Instrumenting the bridge over `java-write-access` shows ZERO value-ACCESSES
candidates reaching the filter: Java field references resolve to a `Property`
target and `isValueDefinitionLabel` covers only Const/Static/Variable, so the
filter is never consulted there. Pipeline-level edge sets are byte-identical with
the filter forced on and forced off, across four shapes — Java cross-file field
writes, Java cross-file constant reads, Java bare same-class constant reads, and
a Python module-constant/class-attribute mix. The defect is real and latent; the
blast radius is not. Fixed anyway, because the predicate asks the wrong question
and the next change that makes the bridge the sole emitter would ship the
deletion for real.

New `value-ref-locality.test.ts` pins the invariant triple — local dropped,
module-scope kept, class member kept — by TARGET rather than by `reason`. The
per-language suites filter on `rel.reason === 'read'|'write'` while the bridge
stamps `scope-resolution: read|write`, so they are blind to bridge-side change in
both directions. The file states plainly which half gates the mechanism (JS,
mutation-verified) and which gates only the outcome (Java, because the mechanism
is unreachable there), so it cannot be mistaken for a stronger gate than it is.

* fix(docs): restore the agent guidance a generated-block refresh deleted

Commit 8f8261021's message is entirely about cross-language anchor reporting; it
also regenerated the `gitnexus:start` block in AGENTS.md and CLAUDE.md against a
LOCAL, non-PDG index and swept six documentation/config files along with it. The
review caught this and it is correct. Restored:

  - the index stats, which regressed 248612 symbols / 565510 relationships /
    918 flows -> 29969 / 118986 / 762 — my machine's index described as the
    project's;
  - the whole `pdg_query` bullet and the PDG half of the impact bullet, while
    both capabilities remain live in `mcp/tools.ts` and `local-backend.ts`;
  - the "Inline staleness signal" section in the guide skill, content that never
    left `origin/main` and that this branch had no reason to touch;
  - `.mcp.json`, which had moved from `npx -y gitnexus@latest mcp` to a bare
    `gitnexus` — a fresh clone with no global install gets a dead MCP server.

The worst of it is self-inflicted in a specific way worth naming: commit
411cac9b9, four hours earlier on this same branch, ADDED the instruction telling
agents not to read `risk: UNKNOWN` as an all-clear. The refresh deleted it. So
the branch shipped a new UNKNOWN verdict and simultaneously removed the guidance
for reading it — the exact false-safe this PR exists to remove, reintroduced one
layer up in the docs.

Re-applied that guidance, and found the drift is wider than reported. The review
noted the `.claude/` copy contradicting the plugin mirror; in fact the UNKNOWN
block was present in ONE of five shipped distributions. `gitnexus/skills/` (the
npm package), `gitnexus-cursor-integration/`, and `.agents/` were missing it too,
so every non-Claude consumer of this skill had the old table.

`shipped-skills-sync.test.ts` passed 54/54 through all of that. Its byte-identical
check covers only the plan/work/review/lfg family, and the standard skills are
guarded solely by per-skill fragment lists — so a fragment nobody listed is a
fragment nothing protects. Added the UNKNOWN fragments to that list, plus a
`copies.length > 1` assertion so an empty copy list cannot make the loop vacuous.
Verified it fails against the pre-fix tree.

* fix(scope-resolution): require the return-shape producer to RESOLVE, not merely to name-match

Review finding 2, reached independently by three Claude lanes and two Codex
legs, and reproduced here. `emitReturnShapeMemberAccesses` took the receiver's
type binding, then filtered a WHOLE-GRAPH property index with `idNamesMember` —
a textual match on the node id. Any node whose id happened to read
`<producer>.<member>` qualified, in any file and any language, and it emitted at
the 0.9 PRECISE tier where a `minConfidence` floor cannot filter it out. The
sibling unique-name pass was given a per-language restriction for exactly this
hazard; this pass consumed the same shared index with none.

Three guards, catching different shapes:

  - the producer must RESOLVE to a definition (`findCallableBindingInScope` — a
    CALLABLE lookup: the producer is the function whose return shape owns the
    member, and it resolves through finalized import bindings so a producer in
    another file still yields its own file);
  - the member must live in that definition's file;
  - that file must belong to the language being resolved.

The third is not redundant with the second, which is the part worth recording.
A receiver typed by CONSTRUCTION (`const bound = new Loyalty()`) resolves through
the shared class registry, which is polyglot — so the producer resolves into
`Loyalty.java`, its members legitimately live in that same file, and file
equality waves the cross-language edge straight through.

Also fixes the sibling P2: a site where the receiver IS typed to a producer that
owns no such member now claims the site. That branch is the strongest negative
evidence the pipeline can produce, and letting it fall through meant the 0.5 name
fallback answered a question the precise pass had just DISPROVED — measured,
linking a read to an unrelated same-named key in another file.

`polyglot-property-isolation` gains the bound-receiver arm the review asked for,
and it is the right arm: the pre-existing case has an untyped receiver and so
only ever exercised the unique-name pass, while one extra token routes an
identical read through this one. Mutation-verified — restoring the pre-fix
matching makes exactly the new leak assertion fail. The first version of that arm
was silently vacuous (it introduced a JS key of the same name, which destroyed
the fixture's Java-only premise), which is why it now asserts on the TARGET FILE
rather than on the absence of a name.

KNOWN LIMIT, stated rather than papered over: a member-call producer
(`const r = svc.make()`) binds `svc.make`, which resolves to no callable, so this
pass now declines it. Codex B3 raised that converse case and it is real. Fixing
it means typing `svc` and then finding `make` on that type — a larger piece of
work, queued for the follow-up PR. Declining is the correct interim behaviour:
the alternative is matching `make.<member>` by name across the graph, which is
the fabrication this commit removes.

* fix(scope-resolution): resolve the import map by point lookup so the seal cannot empty it

Review finding 4, reproduced end-to-end by two lanes: the same commit and the
same repo produced a DIFFERENT graph depending on `GITNEXUS_DISK_SCOPE_INDEX`.

`buildDirectImportMap` built `scopeToFile` by walking `parsed.scopes`. The
out-of-core seal replaces `emitParsedFiles` with a scope-STRIPPED copy — that is
its documented contract, scopes are reachable only via `scopeTree.getScope`
afterwards — so under the seal the map came out empty, every `directImports`
lookup returned undefined, and tier-2 narrowing died repo-wide.

The reporting is the worse half. The loss surfaced as `ambiguous`, which means
"several candidates and the pass refused to choose". The truth was "the evidence
was discarded one function earlier". A reader acting on that would go looking for
better receiver typing to fix a problem that was not there.

This is the SECOND consumer of `parsed.scopes` on this branch to hit the seal.
The first was hoisted above it. This one is converted to the point lookup
instead, which is the stronger fix: a point lookup survives the seal by contract,
so there is no ordering left for a future edit to get wrong.

The parity assertion that would have caught it now exists. The sealed harness in
`javascript-const-references` already ran the fixture both ways, but every
assertion in it pinned ONE field's readers — which is exactly how a second
instance slipped in, since no assertion happened to cover a narrowed name. It now
also compares the WHOLE ACCESSES edge set between the two runs, as a sorted diff
so a failure names the edges that moved, with a non-empty guard so two empty sets
cannot compare equal and assert nothing. Mutation-verified: forcing the map empty
fails it.

* fix(scope-resolution): bind a producer's own returned key to itself, and stop claiming uniqueness for a ranked answer

Review finding 3, accepting the two defects it demonstrates and declining the
remedy it proposes. Both halves are mutation-verified.

1. A SITE INSIDE ITS OWN RETURN SHAPE NOW BINDS TO ITS OWN KEY.

   `export function buildB(row) { return { tickIntervalMs: row.b } }` writes the
   key that IS `buildB.tickIntervalMs`. Ranking declared anchors above return
   shapes is correct for a READ through a receiver, but applied to this site it
   handed the write to a same-named module const that `buildB` never touches —
   a wrong edge — while the node the key actually defines was left with no
   writer at all. Both halves wrong from one rule applied to the wrong shape.

   Checked before every other rule, because it is evidence rather than ranking:
   the owner qualifier on the candidate id and the enclosing callable are the
   same symbol. Nothing outranks that.

2. THE TIER NO LONGER LIES.

   `workspace-unique` is a claim that exactly one node in the workspace carries
   the name — a fact about the graph, and the label a reader trusts most. An
   answer reached by FILTERING (tests down-ranked, return shapes down-ranked)
   is a weaker claim, and it was reported under the same label. The edge is
   unchanged; what it is allowed to say about itself is not. `narrowed` now
   counts these correctly too, since it keys off the tier.

WHAT I AM NOT DOING, and why. The review proposes dropping the same-file and
imported-file tiers "and keeping only genuine workspace-uniqueness". That would
revert the measured R2 result taking backend readers of `exitMinAtrMult` from
0 to 24. Workspace uniqueness was already measured too strict on that repo: the
field carries 26 Property definitions — 16 in one-off scripts, 7 in the
frontend, one in a test, and exactly one in the backend that reads it. Strict
uniqueness declines all 24.

The alternative suggestion — require the receiver to bind to the owning object —
has the same effect by another route: the population this pass exists for is the
untyped option bag, whose receiver binds to nothing. Requiring a binding turns
the pass off for its own use case. So the two demonstrated defects are fixed and
the capability around them is kept, at half confidence, naming its inference in
the reason string, and honoured only where `fieldFallbackOnMethodLookup` allows.

The R3-5 precision test needed rescoping rather than relaxing: it asserted that
EVERY edge to the contested field is a precise return-shape edge, which the
producer's own (correct, name-tier) write now violates. It asserts the reader
edges are precise and the producer's write binds to its own key — two different
claims reached two different ways, which is what the code now models.

* test(bench): re-baseline the JS/TS scope-capture fingerprints for this branch's capture additions

The `Cross-language scope-capture fingerprint + scaling guards` CI step was
failing on TypeScript and JavaScript, and it had been failing for the whole PR —
the branch changed both SCOPE queries without ever updating the guard's
baseline. It only surfaced now because a merge conflict had prevented CI from
running at all, so nothing reported it.

Re-baselined per the file's own instruction ("re-baseline intentionally on a
legitimate capture change"), and verified first rather than rubber-stamped. The
capture-name sets in both scope queries, diffed against `origin/main`:

  TypeScript  + @reference.read.identifier      (A2, bare-identifier reads)
              + @reference.type                 (R2-2, type references)
  JavaScript  + @reference.read.identifier      (A2)
              + @reference.read.destructured    (R2-1c)
              + @reference.write.property-key   (R2-1b)

Nothing removed on either side. A pure superset is the check that no EXISTING
capture moved — which is the failure mode a fingerprint guard exists to catch,
and the reason to look before regenerating.

Consistent everywhere else too: `capture_groups_small`/`_large` are unchanged
(4503/14403) because those measure the SYNTHETIC scaling source this branch does
not touch, so only the fixture-corpus number moves — 2097 -> 2338 across 21 new
lang-resolution fixtures, 146 -> 151 files. Scaling stayed linear and inside
budget (typescript 1.116, javascript 1.010, both < 1.5), so the added rules cost
no super-linear time. Prior and new hashes are recorded in the baseline note, as
every previous entry in that file does.

* test(bench): re-baseline the receiver-resolution drop guard for the new WRITE site kind

Second of the two bench guards that had been failing for the whole PR without
anyone seeing it — CI could not run while the branch was conflicted, so both
went unreported until the merge cleared.

The drift is a new site KIND, not a movement in an existing one:

    totalDropsAllKinds  129 -> 140
    bySiteKind          {call: 102, read: 27}
                     -> {call: 102, read: 27, write: 11}

`call` and `read` are byte-identical, which is the check that matters. This
branch added write-site captures the corpus never had — `@reference.write.
property-key` (R2-1b record construction) and the destructured-read rules — so
write sites reach receiver resolution for the first time, and 11 of them have a
receiver that does not resolve. A drop is the honest outcome for those; the
alternative is the name-inferred guess this series spent three rounds bounding.

Verified it is NOT caused by this session's review fixes before re-baselining:
removing the `memberNotOnShape` site-claim added in 69047086 and re-running gives
the identical 129 -> 140 / write: 11 drift, so the movement predates today and
belongs to the capture work, exactly as the arithmetic above says.

The sibling `scope-emission` guard still PASSES untouched, and the fingerprint
guard passes after 20a937f4 — so all three arms of the benchmarks job are green
locally.

* fix(routes): track boolean polarity in dispatch guards, so a negated condition cannot invent a route

Reproduced exactly as reported. `dispatch-guard.ts` refuses to inherit a verb
from an `if` whose `else` branch holds the comparison — the module's own doc
comment explains why: that branch runs precisely when the condition did NOT
hold, so attributing it is backwards. `!` is the same fact written as an
operator, and it was not handled. A stated invariant with half an
implementation, which is worse than an absent one, because the comment reads as
though it were covered.

Measured against the real extractor before fixing:

    if (!(pathname === '/api/admin'))                  ->  '' /api/admin   INVENTED
    if (!(req.method === 'GET') && pathname === '/x')  ->  GET /x          INVERTED
    if (!(req.method === 'POST' && pathname === '/w')) ->  POST /w         BOTH

And the review is right that this is not additive-only. Driven through the real
pipeline with a policy module that serves nothing plus a one-line route table,
the invented `GET /api/report` collected into `verbedUrls` and
`reconcileDispatchGuardRoutes` then EVICTED the true verb-less route for that
path. A false route deleted a real one. After the fix that repo yields exactly
one route, verb-less, path intact.

Parity, not presence: `!!x` is `x`, so counting negations and testing the parity
is the only rule that keeps a doubly-negated guard working. A negated VERB drops
to verb-less rather than dropping the route — `!(method === 'GET')` means every
method except GET, which no single value expresses, while the path evidence is
untouched. Applies to the regex arm too; `!/^\/api\/x$/.test(pathname)` had the
identical hole.

Deliberately NOT keeping the `statement_block` break from the suggested patch.
It is unreachable — the `!` in `if (!cond) { … }` lives in the condition, a
SIBLING of the block, never an ancestor of anything inside it, and the only
shape that puts a `!` above a block is an IIFE, which the function-boundary stop
catches first. Unreachable in the UNSAFE direction, too: breaking early
under-counts negations, and an under-count reads a negated guard as positive and
invents the route. Verified by mutation — with the break present, deleting it
fails nothing; the other three guards each fail a test when removed.

Six new cases, all previously absent (`grep -c '!(' ` over both test files was 0,
and the only negation covered was `!==`, the form that already worked).

* test(bench): re-baseline the emit-persistence byte-identity fingerprint for the isDetail column

The third bench guard this branch left red, and the one the earlier
rebaseline pass missed: the `benchmarks (GITNEXUS_BENCH)` job has never
succeeded once in eleven attempts, and since step 11 aborts the job, the
two steps after it — the streaming PDG-emit guard and the cross-language
pipeline benchmarks — have never executed at all.

    [emit-persistence --check] FAIL: byte-identity fingerprint drift
      (got 4ee15e74…, expected 69e9182a…)

Cause is this branch's own `isDetail` BOOLEAN on the Property table
(PROPERTY_SCHEMA), which `streamAllCSVsToDisk` writes as one more header
field and one more cell per Property row.

Verified header-only rather than regenerated on faith. Dumping every CSV
the bench emits on both `origin/main` and this branch and diffing them
per file (name, byte length, sha256): the file set is identical at 35
CSVs, 34 of the 35 are byte-identical, and the sole difference is
property.csv growing 68 -> 77 bytes as the header gains `,isDetail`. The
synthetic graph mints no Property nodes, so not one data row moved —
which is the thing this fingerprint exists to catch. Both timing gates
were green throughout (scaling_ratio 0.783 against a 1.8 budget,
elapsed_ms_large 229ms against the 1000ms backstop), so no throughput
claim is being rebaselined away.

Justification recorded in a `_rebaselined_<reason>` key, the convention
bench/scope-capture/baselines.json already sets, and the note now says so
explicitly so the next regeneration records its reasoning too.

* perf(processes): build each trace key once, not once per comparison

`deduplicateTraces` held its `join('->')` inside the `some()` callback, so
every already-kept trace had its key rebuilt from scratch against every
candidate: O(T*U) joins of O(depth * id-length) characters. The
allocation, not the substring scan, is what the pass spends its time on.

Nothing about breadth-first search made that safe. It only hid the cost by
keeping traces short — measured on this repo the walk averaged 4.3 steps
before D1 and 9.4 after, which roughly doubles both the number of
surviving traces and the length of every key, so the same quadratic that
was affordable under BFS is about six times the work under DFS. That is
the whole of the slowdown D1 was carrying; the depth-first walk itself is
cheaper than the queue it replaced (`pop()` against an O(frontier)
`shift()`), and its frontier is bounded by depth rather than by breadth.

Hoisting the join into a `uniqueKeys` array removes the multiplication.
Measured back to back on one host, 5 reps, 25k callables, production sink
path (main -> this branch before -> this branch after):

    deep_chain      876.8ms -> 1233.1ms -> 101.9ms
    mixed_cycles    731.4ms -> 1130.6ms -> 132.8ms
    shallow_wide    572.5ms ->  531.8ms ->  49.6ms

and on the real gitnexus/src corpus (11,490 symbols) process detection
goes 204ms -> 89ms against main, having been slower than main before.

Output is unchanged, which is the property that matters here: swapping the
file back and forth and diffing every non-timing field across all sixteen
shape x scale x sink-variant configurations gives no difference, and the
real corpus returns the same 936 processes / 4,648 steps either way. Sink
keys are pushed alongside the traces they belong to, so the comparison set
is the same set it always was.

* fix(processes): type the parse-output read as ParseOutput

The R3-6 sink read declared its own structural shape for the parse output
instead of naming `ParseOutput`, which made it the only one of the five
parse consumers in the repo not bound to the real type — cross-file.ts,
orm.ts, routes.ts and tools.ts all pass the type argument.

`getPhaseOutput` is a raw `as T` cast, so a local shape checks nothing at
runtime and only severs the compile-time link: renaming `allFetchCalls` on
`ParseOutput` would still compile here and silently detect zero sinks
forever. Verified with a real `tsc --noEmit --strict` run over exactly that
rename — the typed consumers error, this one did not. The runtime `.filter`
stays, since it is the only thing actually guarding the cast.

Also brings the phase docblock back in line with the deps array, which was
missing `structure` (pre-existing) and `parse` (added by this branch), and
records the two parse fields the phase now reads.

fix: remove hardcoded 300-flows cap for large repositories (#2198)
* fix: remove hardcoded 300-flows cap for large repositories

The dynamicMaxProcesses was capped at 300 via Math.min(300, ...),
causing large repositories (280K+ nodes) to lose execution flows.

Change: Remove the Math.min(300, ...) cap, keep dynamic calculation.
Effect: 280K-node repo: 300 → 1617 flows.

* test: add regression for dynamic maxProcesses sizing (#2198)

Verify that processProcesses honours maxProcesses > 300 without truncation.
Addresses the optional follow-up suggested by @koriyoshi2041.

* test: exercise computeDynamicMaxProcesses at the phase layer (#2198)

Extract  from the inline
expression in  so the regression test can exercise the
function that actually contained the removed  cap.

The previous test called  directly with
, which passes regardless of whether the phase-level
cap is present —  never had the cap.

The new test suite covers:
  - floor (20) for tiny repos
  - linear scaling in the 0–3000 range
  - growth past 300 for large repos (the actual regression)
  - explicit assertion that reintroducing Math.min(300, …) would fail

Addresses review feedback from @azizur100389.

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.
