Merge upstream/main into feat/r-language-support

Browse source 
Upstream took SCHEMA_BUMP 133 to 137, so the R provider bump moves to 138.
The pin test and the taken-versions list are updated to match. The import-target
benchmark keeps both the R and Rust arms in the heap-budgeted and context
language lists, and the tree-sitter readiness tests keep the R grammar checks
against the reworked report (R is now a peer-patch grammar and the held-grammar
counts changed).

runtime — things Dependabot can't see:
1. Peer-dep compatibility: when every grammar's *latest npm release* accepts
tree-sitter@0.25.0 (so we can upgrade without --legacy-peer-deps).
2. Vendored upstream drift: whether a vendored grammar's upstream parser.c moved.
1. Peer-dep patches: several grammars' npm peer ranges reject the bundled
runtime, so prepare-tree-sitter-bundle.cjs patches their manifests at pack
time (AUDITED_PEERS). The report flags when npm latest (or upstream main)
accepts the runtime, so a patch can be dropped by bumping the grammar.
2. Intentional pins and vendored holds, plus vendored upstream drift.

* validates the prebuilds — so even an imperfect re-vendor can never silently
* ship: its PR's CI goes red.
*
* ABI awareness is load-bearing. Every grammar is pinned to tree-sitter@0.21.1
* (LANGUAGE_VERSION 13–14, the #1922 gate). Most upstream grammar releases target
* a newer tree-sitter, so a blind "bump to latest" would pull an ABI-incompatible
* parser and open doomed PRs. This monitor fetches the candidate source, reads its
* parser.c `#define LANGUAGE_VERSION`, and only re-vendors when it is 13 or 14;
* incompatible updates are reported (and surfaced as a workflow notice), not
* applied.
* The runtime is tree-sitter@0.25.1 (LANGUAGE_VERSION 13–15). Read the
* candidate's generated ABI before updating; incompatible candidates are
* reported rather than applied. Semantic compatibility is verified by PR CI.
*
* Usage:
* node update-vendored-grammars.mjs # detect only → JSON report on stdout
* node update-vendored-grammars.mjs --apply X # re-vendor grammar X in place
*
* tree-sitter-c and tree-sitter-objc are MONITORED but report-only (`hold`): c is ABI-pinned at 0.21.4
* (#1242/#858) and must not auto-bump without a tree-sitter runtime upgrade, so an
* available c update is detected + reported but never auto-applied — even if it is
* ABI-13/14. A maintainer re-vendors it deliberately.

### Native tree-sitter npm packages
The CLI pins and bundles the native `tree-sitter` runtime and its npm grammars.
Several compatible grammars still declare older runtime peer ranges. Root npm
`overrides` do not propagate to consumers, and older npm versions validate bundled
peers against their original ranges even when an override is configured. The
lockfile therefore pins the same eight audited peers to exactly `0.25.1`.
`gitnexus/scripts/prepare-tree-sitter-bundle.cjs` runs during `postinstall`
and `prepack` to keep installed dependency manifests consistent with that lockfile
and the published bundle. It leaves grammar sources and native binaries unchanged
and rejects unexpected versions, peer ranges, or dependency layouts before writing
any manifests. The upstream ranges remain in the script only as validation inputs;
installed and published audited manifests require exactly `0.25.1`.
When upgrading these packages, update the exact pins, lockfile, and audited peer
list together. If regenerating the lockfile restores upstream's older peer ranges,
restore the same audited `0.25.1` peer pins before committing it. Verify ordinary
`npm ci` and a subsequent `npm install` complete without peer-resolution warnings.
Run the parser, extraction, CFG, and worker tests, then use a real
`npm pack` (including `prepack`) to test a fresh consumer's `npm install`,
`npm ci`, `npm ls`, and a subsequent dependency install. Check native parser
loading on the supported Node.js versions and release platforms. A successful
install in this checkout alone does not verify the published bundle.
### Vendored tree-sitter grammars
`.github/vendored-grammars.json` is the **single source of truth** for the vendored tree-sitter grammar **set** and each grammar's policy `hold` (the ones shipped from `gitnexus/vendor/<name>` rather than installed from npm). It lists each grammar's name, upstream coords (`npm` or `github`), and any `hold`. The monitor resolves upstreams from it; the readiness report keeps its own upstream-drift coords and reads vendored ABIs from `gitnexus/vendor/`. Two workflows read it:
- `grammar-update-monitor.yml` (`.github/scripts/update-vendored-grammars.mjs`) — weekly; opens auto-PRs re-vendoring ABI-compatible upstream updates.
- `tree-sitter-upgrade-readiness.yml` (`.github/scripts/check-tree-sitter-upgrade-readiness.py`) — daily; renders the tree-sitter-0.25 readiness report (issue #858), reading each vendored grammar's ABI from `gitnexus/vendor/<name>/src/parser.c`.
- `tree-sitter-upgrade-readiness.yml` (`.github/scripts/check-tree-sitter-upgrade-readiness.py`) — daily; renders the tree-sitter compatibility-workarounds report (pack-time peer patches, intentional pins, vendored holds; issue #858), reading each vendored grammar's ABI from `gitnexus/vendor/<name>/src/parser.c`.
Sharing the manifest keeps the two aligned: a consistency-guard test asserts the manifest set equals the `gitnexus/vendor/tree-sitter-*` directories. **When you vendor a new grammar (or remove one), update `.github/vendored-grammars.json` in the same change** — otherwise that guard fails CI and the readiness report regresses to `?` placeholders.

### Analyze reports INCOMPLETE with a collapsed graph write
- **Trigger:** `npx gitnexus status` reports `incompleteReasons: ["graph-write-collapsed"]`; the analyze summary printed `Repository indexed INCOMPLETELY` naming an expected and a persisted relationship count, and the CLI exited non-zero.
- **Do:** Re-run `npx gitnexus analyze --force`. If it recurs, check free disk space on the volume holding `.gitnexus/`, confirm no second `analyze` is running against the same repo (both stage through `.gitnexus/csv`), then run `npx gitnexus doctor`.
- **Why:** The run finished and wrote metadata, but far fewer relationships are readable back than the pipeline produced. Nothing throws: the DB holds rows and the metadata is valid, so every query answers with missing edges rather than an error — a confident empty answer, which is worse than a failure because it looks like a result. Unlike `incremental-in-progress` and `embedding-checkpoint-pending`, which describe a run that did what it said and left work for next time, this one means most of your edges are gone, so it is the one incomplete reason that also fails the exit code. The check compares in-memory totals (including rows streamed out of the heap) against the post-write count, refuses to answer when the count cannot be read, and is skipped on incremental runs where whole-scope counts are not comparable.
- **Trigger:** Analysis rejects a staged graph write with expected and persisted relationship counts, or an in-place run prints `Repository indexed INCOMPLETELY`, exits nonzero, and records `incompleteReasons: ["graph-write-collapsed"]`.
- **Do:** Inspect COPY errors, available memory, and free disk space on the volume holding `.gitnexus/`; confirm no second `analyze` is running against the same repo, then run `npx gitnexus doctor`. For native buffer-pool exhaustion, see [RUNBOOK.md](RUNBOOK.md#memory--analyze-crashes) for `GITNEXUS_LBUG_BUFFER_POOL_SIZE` and memory-budget guidance. Re-run `npx gitnexus analyze --force` after addressing the cause.
- **Why:** Far fewer relationships are readable back than the pipeline produced. A staged build throws before publication and preserves the previous index, if any. In-place writes cannot roll back, so the incomplete stamp and nonzero exit prevent a partial graph from being presented as successful. Recognized buffer exhaustion also throws immediately during COPY or fallback inserts. The collapse check compares in-memory totals (including streamed rows) against the post-write count, stays unmeasurable when the count cannot be read, and is skipped on incremental runs where whole-scope counts are not comparable.

Analyze re-execs Node with a **large old-space heap** when needed (`analyze.ts`). If you still OOM on huge repos, close other processes, avoid `--embeddings` for a first pass, or analyze a smaller path if supported by your workflow.
`Unable to allocate memory` / `The buffer pool is full` during graph writes
refers to LadybugDB's native buffer pool. Increasing `NODE_OPTIONS`,
`--memory-budget`, or worker heap limits does not resize that pool. Recognized
pool exhaustion aborts analysis instead of retrying with row skipping.
If the host has enough memory, set an explicit pool size in **bytes**, then
rebuild. For example, 3 GiB is `3221225472` bytes:
```bash
GITNEXUS_LBUG_BUFFER_POOL_SIZE=3221225472 npx gitnexus analyze --force
```
The override bypasses automatic pool sizing. Budget for the Node heap, parse
workers, other native allocations, and the OS alongside it; a larger pool can
exhaust the host. `GITNEXUS_LBUG_BUFFER_POOL_SIZE=0` restores LadybugDB's native
80%-of-RAM default, not an unlimited supply of memory. If memory is insufficient,
exclude generated/vendor directories or use a larger host.
A measured graph-write collapse aborts a staged build before publication,
leaving the previous index, if any, intact. An in-place run cannot roll back:
it records `graph-write-collapsed` and exits nonzero. Rebuild a previously
collapsed index with `--force` after addressing memory, disk space, or the
reported COPY error; do not rely on its incomplete query results.

# Local import scoping
GitNexus resolves statically known local imports through their lexical owner and
actual declaration identity. A nearer name that is unresolved, unavailable, or
noncallable blocks an unrelated outer or workspace fallback. An absent name can
continue through the existing lookup rules. This is static analysis: it does not
execute loaders or infer arbitrary runtime initialization order.
## Shared contract
Language rules stay in providers. The shared
[name-claim lookup](../../gitnexus-shared/src/scope-resolution/name-claims.ts)
distinguishes `absent`, `blocked`, and `resolved` before filtering by target kind.
Its [regressions](../../gitnexus/test/unit/scope-resolution/lexical-name-claims.test.ts)
cover noncallable barriers, unresolved imports, type/value lookup, declaration
positions, and inferred aliases that retain their initializer's lookup position.
Calls, constructors, receiver/type inference, inheritance, namespace lookup, and
fallback consumers use these ownership facts rather than independently choosing a
same-named symbol.
The [shared records](../../gitnexus-shared/src/scope-resolution/types.ts) carry
ownership, activation positions, directive destinations, and lookup purpose as
serializable data. They retain declaration identity and ambiguity; they contain
no AST nodes or callbacks. `declaredAtScope` describes ownership, while
`runsOnlyWhenCalled` describes deferred execution. A function-local Rust `use` or
C `#include` is not deferred merely because of its position; Python and Ruby
loading can be. The
[function-local import chain tests](../../gitnexus/test/unit/scope-resolution/function-local-import-chain.test.ts)
pin that distinction.
## Providers with expanded lexical support
These seven entries are part of the
[18-provider registry](../../gitnexus/src/core/ingestion/languages/index.ts).
The evidence links cover exact targets and negative cases, not just edge counts.
| Provider | Supported behavior | Source and regression evidence |
| --- | --- | --- |
| Python | Function-local named, aliased, and namespace imports; compiler-local ownership; ordered class lookup; `global`/`nonlocal` destinations. | [Lexical facts](../../gitnexus/src/core/ingestion/languages/python/lexical-bindings.ts), [local imports](../../gitnexus/test/unit/scope-resolution/python/python-local-imports.test.ts), [namespace semantics](../../gitnexus/test/integration/resolvers/python-namespace-semantics.test.ts) |
| TypeScript | Literal genuine `require`, immediately awaited `import`, and import-equals; namespace, named, and renamed bindings; type/value separation. | [Loader collector](../../gitnexus/src/core/ingestion/languages/typescript/local-loaders.ts), [loader tests](../../gitnexus/test/unit/scope-resolution/typescript/local-loader-imports.test.ts), [type ownership](../../gitnexus/test/unit/scope-resolution/typescript/lexical-type-ownership.test.ts) |
| JavaScript | The same supported runtime loaders and lexical barriers, using JavaScript captures for JS/JSX. | [Captures](../../gitnexus/src/core/ingestion/languages/javascript/captures.ts), [JS/JSX loader cases](../../gitnexus/test/unit/scope-resolution/typescript/local-loader-imports.test.ts) |
| Vue | Local loader facts in extracted scripts, with original declaration graph positions preserved. Explicit JS/JSX uses its own semantic grammar inside the worker; TS reuses the cached tree. | [Script delegation](../../gitnexus/src/core/ingestion/languages/vue/captures.ts), [direct/pre-extracted parity](../../gitnexus/test/unit/scope-resolution/typescript/local-loader-imports.test.ts), [real workers](../../gitnexus/test/integration/local-import-worker-parity.test.ts) |
| Rust | Lexical `use`, producer identity for imported factories/types, and Cargo-aware crate/module identity. Unresolved explicit imports block unrelated fallback. | [Lexical facts](../../gitnexus/src/core/ingestion/languages/rust/lexical-bindings.ts), [import targets](../../gitnexus/src/core/ingestion/languages/rust/import-target.ts), [local scope](../../gitnexus/test/integration/resolvers/rust-import-scope.test.ts), [Cargo boundaries](../../gitnexus/test/integration/resolvers/rust-cargo-target-fallback.test.ts) |
| C++ | Position-sensitive local `using` declarations/directives, separate from includes; propagated header claims retain unresolved named `using` barriers. | [Captures](../../gitnexus/src/core/ingestion/languages/cpp/captures.ts), [local using](../../gitnexus/test/integration/resolvers/cpp-local-using.test.ts), [header using](../../gitnexus/test/integration/resolvers/cpp-local-using-headers.test.ts) |
| Zig | Literal `@import` namespace/member bindings, block activation, container hoisting, stable deep aliases, and inline `@import` receivers. | [Captures](../../gitnexus/src/core/ingestion/languages/zig/captures.ts), [local imports](../../gitnexus/test/integration/resolvers/zig-local-imports.test.ts), [static gating](../../gitnexus/test/integration/resolvers/zig-static-gating.test.ts) |
### Python boundaries
Compiler-local binders include parameters, assignment patterns, loop/with/except
targets, match captures, augmented assignment, deletion, and comprehension/walrus
bindings. Comprehension targets do not leak, and the first iterable is evaluated
outside the comprehension environment. Class bodies use ordered locals; methods
skip class locals for bare-name lookup while explicit instance receivers remain
available. Annotation-only declarations distinguish compiler ownership from a
runtime store. These cases are characterized in the
[Python local-import tests](../../gitnexus/test/unit/scope-resolution/python/python-local-imports.test.ts).
Mixed import/value rebinding and conflicting import identities conservatively
abstain throughout the environment, including simple sequential rebinding; this
is not a control-flow evaluator. A definite `def`/`class` declaration can still
supply its own target after activation. The
[provider policy](../../gitnexus/src/core/ingestion/languages/python/lexical-bindings.ts)
and [rebinding regressions](../../gitnexus/test/integration/resolvers/python-namespace-semantics.test.ts)
define this boundary. There is no full annotation evaluator, `exec` evaluation,
or general closure scheduling model. A deferred `global`/`nonlocal` installer is
not assumed to have executed for unrelated callers.
Conditional imports with one compatible identity remain available for structural
reference resolution, including `TYPE_CHECKING` annotations and `try` imports.
Their runtime execution is not guaranteed by a resolved graph edge.
Default expressions look up names in the enclosing environment. FastAPI's
synthetic dependency graph caller is recorded separately as `callerScope`; it
does not move lexical lookup into the handler body. Both
[direct extraction](../../gitnexus/test/unit/scope-resolution/python/python-local-imports.test.ts)
and [worker transport](../../gitnexus/test/integration/local-import-worker-parity.test.ts)
check this distinction.
### JavaScript-family boundaries
Loader recognition checks AST shape and binding identity, including parameters,
catch/destructuring bindings, temporal-dead-zone ownership, and writes to the
loader or imported handle. CommonJS forwarding uses that same identity check.
Reassigning one destructured import leaves unchanged sibling re-exports intact.
Writes to ordinary locals retain their declared type and callable-value facts.
Unawaited dynamic imports remain Promise/file-dependency facts rather than module
namespace aliases. Computed specifiers, indirect loader/Promise chains, and
unsupported destructuring remain unresolved; see the
[loader regressions](../../gitnexus/test/unit/scope-resolution/typescript/local-loader-imports.test.ts).
Vue's explicit JS/JSX script requires an additional bounded semantic parse because
the worker's structural tree uses TypeScript. That parse runs inside the real
worker. The [parity test](../../gitnexus/test/integration/local-import-worker-parity.test.ts)
witnesses returned worker facts; a main-thread fallback does not satisfy it.
### Rust, C++, and Zig boundaries
Rust uses Cargo editions, target roots, and module identities, including files
with multiple valid identities. Reusable per-analysis indexes bound repeated
lookup work; this is not a claim of a global indexing speedup. See
[Cargo metadata](../../gitnexus/src/core/ingestion/languages/rust/cargo-targets.ts)
and its [tests](../../gitnexus/test/unit/scope-resolution/rust-cargo-targets.test.ts).
Exact same-name inline `pub use` forwarding is supported. A forwarding alias that
changes symbol spelling through a file-only target conservatively remains
unresolved; ambiguous same-file homonyms and re-export cycles cannot select an
unrelated declaration. These limits are explicit in the
[Cargo fallback regressions](../../gitnexus/test/integration/resolvers/rust-cargo-target-fallback.test.ts).
Inferred receiver types retain their receiving declaration range. When same-block
shadowing replaces a retained type fact, earlier uses cannot consume the later
declaration's type and may remain unresolved; this is not full SSA inference. See
the [factory ownership regressions](../../gitnexus/test/unit/scope-resolution/rust/rust-range-binding-order.test.ts).
C++ includes keep their compilation-unit behavior alongside lexical `using`.
The header tests cover literal includes, declaration positions, unresolved named
using claims, and overload identity. They do not establish a full preprocessor,
namespace-alias evaluator, or arbitrary transitive `using namespace` chain support.
Zig nonliteral imports remain unresolved; its block-local names do not escape or
activate before their declarations.
## Retained provider behavior
The other eleven providers retain their existing import/loading models. This
work does not reinterpret every dependency construct as a local value import.
| Provider | Retained model and boundary | Evidence |
| --- | --- | --- |
| Ruby | Wildcard loading; method-local loading is deferred. The extractor recognizes string arguments to `require`, `require_relative`, and `load`. The linked behavioral tests establish `require`/`require_relative` and deferral, not arbitrary `load` execution. | [Extractor](../../gitnexus/src/core/ingestion/languages/ruby/captures.ts), [loading](../../gitnexus/test/integration/resolvers/ruby-scope.test.ts), [deferral](../../gitnexus/test/unit/scope-resolution/function-local-import-chain.test.ts) |
| PHP | Namespace `use` imports are distinct from closure capture and trait `use`.

## Taint provenance
Taint source, sink, and sanitizer matching uses the same lexical provenance.
A genuine external import may match its raw module name even when that package
has no indexed source. A sibling import, local shadow, or type-only import cannot
authorize that match. General copied-handle tracking is outside this support.
The [taint regressions](../../gitnexus/test/unit/taint/lexical-imports.test.ts)
cover extraction, emission, and function summaries, including abstention when
exact call-site positions are missing.
## Cache migration and verification evidence
[Parse-cache schema 136](../../gitnexus/src/storage/parse-cache.ts) replaces 133,
134, and 135. It invalidates overly broad Python/TS/JS binding barriers,
incorrect parameter-annotation lookup ownership, and embedded Vue grammar and
source positions. The same version gate applies to the
[durable ParsedFile store](../../gitnexus/src/storage/parsedfile-store.ts).
Incompatible records are rejected and rebuilt on the next analysis; unchanged
records can then be reused. The
[schema regression](../../gitnexus/test/unit/incremental-parse-cache.test.ts)
explicitly rejects valid schema-133, schema-134, and schema-135 records in both stores.
PDG-mode chunk keys also advance to `pdg:6`, so embedded-script CFGs with
incorrect call anchors are rebuilt before the resolved-callee join.
The [real-worker parity suite](../../gitnexus/test/integration/local-import-worker-parity.test.ts)
witnesses worker boot, dispatch, and returned ParsedFiles, then compares complete
provider facts with direct extraction, including `callerScope` and C++ side-channel
data. Optional grammar availability is explicit in the test gate.
The [persistence suite](../../gitnexus/test/integration/resolvers/local-import-persistence.test.ts)
loads both stores afresh from disk. Its parse-cache chunks contain no embedded
ParsedFiles, so warm equality requires durable-store reuse. It checks identical
`CALLS`/`IMPORTS` identities with zero extraction and zero worker dispatch on an
unchanged warm run. Editing a local import target or shadowing `require` removes
the stale target, and a second warm run preserves the edited graph.
Both suites are in the [cross-platform manifest](../../gitnexus/scripts/cross-platform-tests.ts);
the [shard regression](../../gitnexus/test/unit/cross-platform-shard.test.ts)
ensures each is selected exactly once across the four Windows/macOS shards.
[CI](../../.github/workflows/ci-tests.yml) owns native execution on those systems;
Ubuntu's full suite discovers the tests normally. These are focused evidence
boundaries, not a statement that the final full suite or every platform has passed.
## Relationship to main and issue #3499
The integrated main baseline `50aa4be3` already includes #3502's nested Python
declaration ownership fix for the original #3499 case and #3504's aliased package
re-export fix. Their [Python integration coverage](../../gitnexus/test/integration/resolvers/python.test.ts)
and [module namespace coverage](../../gitnexus/test/unit/scope-resolution/python/python-module-namespace-construction.test.ts)
remain relevant. This branch extends that base with the lexical claims, provider
semantics, and persistence evidence described above. Issue coverage is **Related
#3499**; this document does not assert that all dynamic Python behavior is solved
or make an issue-status claim.

## Release evaluation
### RC regression decision
`workflow_bench.release_gate` compares a candidate report with a freshly
measured stable-runtime report. Both reports must use the same trusted harness,
task/oracle pins, model, reasoning effort and repetition count. Each task must
solve at least as many repetitions with the candidate as with stable; gains on
one task cannot offset losses on another. Invalid, stale or incomplete evidence
fails closed. Cost, duration and both no-GitNexus comparisons remain descriptive
measurements, not additional pass criteria or claims of statistical significance.
```bash
uv run --locked --extra dev python -m workflow_bench.release_gate \
--candidate candidate/agent-evaluation.json --candidate-sha <full-rc-sha> \
--stable stable/agent-evaluation.json --stable-sha <full-stable-sha> \
--out public
```
The command writes `release-quality-gate.json` and `release-quality-gate.md`
and exits nonzero on rejection. Its caller must authenticate the reports and
resolve the published stable and exact candidate revisions independently;
self-reported metadata does not establish provenance. Release evaluation
resolves the latest published stable release and the requested candidate
itself, then measures both with main's trusted harness. The comparison is a
regression signal for published RCs; it does not block RC publication.
### Current workflow
Following [discussion #3493](https://github.com/abhigyanpatwari/GitNexus/discussions/3493#discussioncomment-18772530),
release evidence is split by cost:
1. Every CI run, RC and stable release runs the offline
[tool-accuracy corpus](../../gitnexus/bench/tool-accuracy/README.md) against
the real ingestion pipeline and tools. Its fixed answers cover #3486–3491
and #3497–3499. `accuracy.json` and `accuracy.md` report every failing answer,
precision/recall and source/fixture revisions. The initial reviewed gaps
remain failures in the accuracy total. The gate rejects new/worsened failures,
missing outputs and repaired allowances that have not been removed.
2. **Release evaluation**, before each stable release and weekly against the
latest RC, runs three fresh paired repetitions of every scenario
on both candidate and stable runtimes, including the expensive task, using
`baseline_nomcp` and MCP `baseline`.
Every task starts at the immutable v1.6.12 commit; all four tasks remain
unsolved there. The hidden graders have tested negative/positive controls,
including retry implementations in either the pipeline or worker pool.
Run **Release evaluation** from `main` before cutting a stable tag. Set
`candidate_ref` to the full, already-reviewed stable commit SHA. The workflow
uses main's trusted harness and `--gitnexus-root` to select a separate immutable
runtime checkout.
Candidate installs run in Bubblewrap with only that checkout (minus `.git`)
writable, system tools read-only, and a cleared environment. Locked downloads
run without package scripts; every lifecycle script then runs with no network. The trusted harness
and host command files are not mounted into the candidate build.
Before any paid sessions, `workflow_bench.release_preflight` builds and
materializes the real sanitized graphs for both runtimes on the runner's temp
filesystem. A copy or containment failure stops the workflow at that point.
Buffered copies use the same 2 GiB hard ceiling as snapshot capture, including
on filesystems without reflinks. This preflight adds an offline graph build per
runtime; the measured runner rebuilds its own graphs to retain its existing
provenance and cache lifecycle. Preflight output is not release evidence.
The report records runtime/harness SHAs, task and oracle digests, model/effort,
every repetition, solve counts, cost and agent wall time. Failed
solutions stay in the denominator. Infrastructure/session failures, missing
costs, incomplete pairs or failed containment make evidence incomplete.
Stable publishing requires a successful default-branch evaluation for that
**exact commit, measured by main's current evaluator**, no more than seven days
old. The publish job loads `eval/` from main's head rather than the release
commit, so later task changes on main do not strand an already-measured
release. A report counts only when its `harness_sha` is the commit its
scheduled or manually dispatched `main` run executed, and GitHub's comparison
from that commit to main's head changes nothing under `eval/`,
`.github/workflows/release-evaluation.yml` or `.github/claude-canary-runtime/`.
An unavailable or truncated (300-file) comparison rejects the run. Any change
to the harness, graders, task pins or agent CLI therefore requires a fresh
Release evaluation. Runs are tried newest first; a rejected run does not hide an
older valid one, and when none passes the error lists each rejection.
It validates task pins, individual cells and recomputed totals before publishing to npm
or either Docker registry. Docker publication also runs the cheap accuracy
gate once before both image builds, then builds the verified immutable commit.
Every release attaches the cheap accuracy evidence; stable releases also attach
and include their paired agent report. RCs publish after CI without waiting for
a paid run. The weekly comparison checks that the latest RC preserves each
covered task's MCP solve count relative to stable. The comparison does not require GitNexus to beat the no-MCP arm or claim that
four tasks establish general improvements.
The Wednesday release comparison reuses the existing schedule controls:
`GITNEXUS_EVOLUTION_ENABLED=true` and `GITNEXUS_EVOLUTION_WORKERS=3` enable
both weekly workflows; disabling evolution also disables scheduled release
comparisons. No additional opt-in variable or model credential is required.
Manual release evaluation remains available independently. Scheduled runs
resolve the newest published RC to its
commit before execution. The protected `gitnexus-evolution` environment remains
restricted to main and supplies the existing model secrets. Evaluation runs on
the dedicated self-hosted EC2 runner. The paid step has a 19-hour cap inside a
21-hour job and also stops 90 minutes before the configured external shutdown,
leaving time to upload summaries when a benchmark step fails. Raw transcripts, internal instructions, local
paths and session files are never uploaded or attached to releases.
The no-GitNexus arm receives no indexed graph, registry, runtime mounts or CLI
wrapper, and inherited graph-first directives are removed while ordinary
repository development and test guidance is preserved. Both arms load that
guidance through the same startup mode. Skills/commands and GitNexus MCP tools
are disabled in the no-tool arm, and repository/plugin hooks are disabled in
both arms. It fails closed when Bubblewrap is unavailable. It retains the repository source and
ordinary test dependencies required by the tasks; rebuilding tools from that
source is not prevented. The comparison therefore measures access to the
provided GitNexus tools and their readable compiled runtime on these GitNexus
development tasks. That runtime can contain later fixes absent from a task's
historical base, so the comparison cannot isolate tool assistance from access
to those implementations.
This corpus uses a **fresh index at each task base**. A nightly stale Hermes
index is a separate condition and must not be pooled with it. Import the
reporter's sanitized task bundle and Hermes fresh/stale fixtures when available;
private repositories and raw transcripts are outside the current corpus.

Both skill evolution and release evaluation manage the existing dedicated EC2
runner through hosted startup and cleanup jobs. They share a concurrency group
for the whole run, so neither can stop the instance during the other's work.
GitHub keeps only one pending run per group, even with `cancel-in-progress:
false`: a newer queued run of either workflow cancels the older pending one.
A release evaluation dispatched for a stable publish can therefore be dropped
while it waits behind a running evolution. Do not queue another run behind a
pending release evaluation, and confirm its **Start the dedicated EC2 runner**
job ran before relying on its evidence. If the run shows Cancelled, dispatch it
again once the group is free.
Startup waits for EC2 running and both health checks, then a native pickup probe
must finish within five minutes. If the probe fails, the hosted check cancels
its own run to clear the queued job. A second hosted watchdog bounds pickup of
the paid job. Only these watchdogs have Actions write permission.
The protected `gitnexus-evolution` environment holds these four settings
(configured and verified by the live probes below):
| Setting | Kind | Purpose |
| --- | --- | --- |
| `GITNEXUS_EVOLUTION_AWS_ROLE_ARN` | Secret | AWS role assumed through GitHub OIDC |
| `GITNEXUS_EVOLUTION_EC2_INSTANCE_ID` | Secret | Dedicated runner instance |
| `GITNEXUS_EVOLUTION_AWS_REGION` | Variable | Instance region |
| `GITNEXUS_EVOLUTION_STOP_SCHEDULE_UTC` | Variable | Actual weekly EventBridge stop, `DAY HH:MM` UTC |
No long-lived AWS credential is stored. The AWS action obtains short-lived
credentials using GitHub OIDC. The role trusts only this repository's
`gitnexus-evolution` environment and permits EC2 DescribeInstances and
DescribeInstanceStatus, with StartInstances and StopInstances scoped to the
dedicated instance. Missing configuration or access fails closed.
The workflow does not create IAM roles, instances, secrets or schedules.
A main-branch dispatch of either workflow with `runner_only=true` starts the
instance, proves native runner pickup, then stops it without paid model calls.
Cleanup runs on a hosted runner after success or failure and verifies EC2 is
actually `stopped`; an accepted StopInstances response alone does not pass.
Startup failures also attempt immediate cleanup. Keep the existing EventBridge
stop watchdog enabled because interrupted or force-cancelled GitHub cleanup
cannot guarantee shutdown. Paid work respects the earlier of the configured
weekly stop and a 24-hour cap, with a 90-minute evidence reserve.
Choose **Re-run all jobs** after a failed run to repeat startup and pickup.
Partial retries cannot reuse a previous attempt's startup: the affected probe
or paid job runs on a hosted runner and fails promptly with that instruction,
instead of waiting on the stopped instance.
PR tests use a fake AWS CLI to cover transitions, denial, lost responses,
timeouts, cleanup and workflow wiring. On 2026-10-09, `runner_only=true`
dispatches of both workflows started the instance, ran the native pickup probe
on the dedicated runner and verified the instance stopped (runs 37893007912 and
37895899767, from temporary branches with a runner-only guard exception).
CI separately runs a six-cell paired evaluator canary using the real pinned
Claude CLI, Bubblewrap, built MCP runtime, hidden grading and public report
commands. Only its small corpus and local model replies are scripted. One
failed repair must stay in the report. This proves execution and accounting;
the canary is not paid-model performance evidence for a stable release.
A review generation is 6 tasks × 3 arms × 3 runs. Serial workers=1 at ~19
minutes per session is a 16-hour job (run 33962002890). Two harness changes
cut that without shrinking the gate:

Nothing is traded away — community detection, process extraction, PDG taint summaries and the local-symbol pruner all read a complete relationship set and behave identically. Set to `0` only to bisect a suspected streaming-related fault. |

### Analysis runs out of memory
If graph writes fail with `Unable to allocate memory` or `The buffer pool is
full`, LadybugDB's **native buffer pool** is exhausted. Analysis stops on these
errors rather than retrying with row skipping. This pool is separate from the
Node/V8 heap and parse-worker budgets; raising `NODE_OPTIONS`,
`--memory-budget`, or worker heap limits does not increase it.
On a host with memory to spare, override the pool in **bytes** and rebuild:
```bash
# 3 GiB native pool; leave room for Node, workers, other native memory, and the OS
GITNEXUS_LBUG_BUFFER_POOL_SIZE=3221225472 npx gitnexus analyze --force
```
An explicit value bypasses automatic pool sizing and can exhaust the host if
set too high. `0` restores LadybugDB's native 80%-of-RAM default; it does not
provide unlimited memory. Reduce the indexed scope or use more RAM when the
combined budgets do not fit. A collapsed staged build is discarded before
publication, preserving the previous index if one exists. In-place collapse
leaves an incomplete index and exits nonzero; recover with `--force` once the
underlying problem is fixed.
Memory management is automatic: `analyze` sizes its heap to the machine
(always below physical RAM), caps each parse worker, and — rather than
grinding into a GC death spiral or crash — stops early with a message telling

# Deterministic tool accuracy
This small release corpus implements the cheap tool-level checks proposed in
[discussion #3493, comment 18772530](https://github.com/abhigyanpatwari/GitNexus/discussions/3493#discussioncomment-18772530).
The fixed answers come from local fixture source and public issue repros; the
current engine output never defines the expected answer.
With the repository's dependencies installed, run from `gitnexus/`:
```bash
node --import tsx bench/tool-accuracy/run.ts --check --out bench/tool-accuracy/results
npm test -- test/unit/tool-accuracy-score.test.ts
```
The runner uses the real `runPipelineFromRepo`, CSV/database loader, metadata
writer and `LocalBackend.callTool`. It indexes one small temporary TS/Python
repository with PDG enabled and one parser worker. Community/process discovery
is unnecessary for these checks and is disabled. Native parser workers require
the normal build produced by `npm ci`; run `npm run build` after worker changes.
The registry, database and fixture copy are isolated and removed after the run.
Fixture code is parsed, never executed. Extension installation is disabled,
accidental JavaScript fetches fail, and neither embeddings nor paid models run.
`accuracy.json` contains source SHA, working-tree status, fixture SHA-256, issue
IDs, expected/actual answers, precision/recall and raw tool outputs.
`accuracy.md` gives the same fixed-answer verdicts and concise failed answers.
`--out` selects a report directory. Without `--check`, valid observations can be
reported while a new fixed-answer failure is investigated; execution/output
errors always exit nonzero. `--check` additionally enforces the regression gate.
| Fixture / checks | Public repro | Fixed-answer contract |
| -------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `rename/` | [#3486](https://github.com/abhigyanpatwari/GitNexus/issues/3486) | All three Writer.close references; zero edits to comments, strings or unrelated homonyms. |
| `src/server/`, `test/stub.test.ts` | [#3487](https://github.com/abhigyanpatwari/GitNexus/issues/3487) | Server beats a same-path test stub; `app.all` has method `*`; Map.get is absent; helper-registered literal route is present. |
| `src/web/` | [#3488](https://github.com/abhigyanpatwari/GitNexus/issues/3488) | Both the base-URL template passed to a configured wrapper and a direct literal fetch link their consumer files. |
| `src/security.ts`, `src/server/inline.ts` | [#3489](https://github.com/abhigyanpatwari/GitNexus/issues/3489), [#3490](https://github.com/abhigyanpatwari/GitNexus/issues/3490), [#3491](https://github.com/abhigyanpatwari/GitNexus/issues/3491) | Named and inline unsafe handlers reach the sink; guarded and constant commands have zero taint; statement and function-hop lines are 1-based. |
| `pkg/` | [#3497](https://github.com/abhigyanpatwari/GitNexus/issues/3497) | Direct, chained module-return helper and local module-return helper resolve to the same target. |
| `mod.py`, `callers.py` | [#3498](https://github.com/abhigyanpatwari/GitNexus/issues/3498) | Direct, conditional, boolean and module-qualified annotated factories resolve to C.m. |
| `nested*.py`, `local_import.py` | [#3499](https://github.com/abhigyanpatwari/GitNexus/issues/3499) | Imports resolve within their lexical scopes; unrelated nested declarations and sibling-local imports cannot capture bare calls. |
| `summary.py`, 501 deterministic drop records | [#3497](https://github.com/abhigyanpatwari/GitNexus/issues/3497) | Production `summarizeUnresolvedReceivers` retains 500 names and reports one omitted name; querying a capped-out name requires `lower-bound`, while a complete empty summary permits `exact`. |
The 501-name case supplies known suppressed outcomes to the production summary
writer, persists its actual output as metadata and calls real `impact`. It tests
the cap/consumer contract without requiring 501 parser fixtures. It does not
claim parser coverage for those synthetic records. Python checks read actual
`context.outgoing.calls` symbol UIDs, preserving lexical/class ownership.
## Known gaps and repairs
The initial source baseline is
`dd096e690c06e5d54ab3595c63b83f15e04b6191`: **11/31 fixed answers pass, 20 fail**.
Main at `50aa4be3b2c2c9a1561fc44878e5d8f87b99d16e` repaired three #3487 route
checks and all four #3499 checks, and their allowances were removed: **18/31
pass, 13 fail**.
The JSON report records every desired and actual answer independently of gate
status. Callback and guard taint findings are currently documented limitations;
their stronger desired answers remain visible as known gaps.
`known-gaps.json` is an explicit, reviewed list of failing check IDs with issue,
reason and observed baseline answers. There is no wildcard, skip, automatic
baseline-update command or production-engine fix in this corpus. The gate:
- Rejects new failing checks, unknown/malformed allowances and missing/malformed
tool outputs, exceptions, truncation and incomplete fixture extraction.
- Rejects a previously correct fact disappearing or a new incorrect fact
appearing inside an existing gap. Partial repairs can still proceed.
- Rejects a passing check whose allowance remains: **remove the allowance in the
PR that repairs the case**, so the fixed answer protects future releases.
Changing a fixture requires reviewing its fixed answers and the line anchors in
`FIXTURE_ANCHORS` (`expectations.ts`); the runner and a unit test fail when an anchor
no longer matches its fixture line. Broadening an allowance requires review of the actual repro;
