fix(taint): report inline and factory handler flows (#3612)
* fix(taint): cover inline and returned handlers (U8) Join expression-handler CFG summaries to distinct graph functions without changing existing anonymous-owner identities. Keep named function expressions private to their lexical scope. Related: #3489 * fix(ci): encode inline handler taint paths (U8) Use codec-safe generated display names while preserving positional function identity. Verify persisted hop continuity and remove the repaired inline-flow accuracy allowance. * fix: keep anonymous names unbound (U8) * test: pin inline callback captures (U8) * ci: run inline taint guard (U8) * test: align inline handler contracts (U8) Pin callback-owned call edges while preserving nested callable IDs and module-level HOC attribution. Assert repaired inline flows and the retained captured-closure limitation. * ci: run native inline proofs on all OSes (U8) Register real-worker identity/CFG and persisted explain cases on the existing Windows/macOS matrix. Charge explicit scheduling estimates without changing watchdogs or runtime behavior. * test(taint): reject all enclosing factory sources --------- Co-authored-by: Gergo Magyar <gergomagyar0@gmail.com> |

fix(rename): apply the exact reviewed edit plan (#3617)
* fix(rename): bind apply to reviewed plans (U7) Retain exact semantic edits behind single-use preview tokens and reject source, target, inventory and graph drift before application. Preserve explicit partial-write accounting and keep large unedited sources covered with hashes instead of retained text. Refs #2973 * fix(rename): cover unindexed sources (U7) Address PR #3617 review by binding every supported source to streamed byte hashes and canonical targets, including tracked and untracked files absent from the graph. Keep the exact reviewed edits and bound evidence memory. Use conventional even-sample medians and extend the existing CI benchmark to capture and validate unindexed sources without relaxing timing gates. Note: pre-existing packed Tree-sitter GLIBCXX_3.4.31 host failure in parse-cache-identity-package.test.ts is not addressed by this PR. * fix(rename): preserve lazy startup (U7) Keep language providers off the MCP startup path; load their existing classification only when rename inventory is requested. The existing 12 startup closure checks now pass. Address PR #3617 review by including token validation in reviewed apply timing and growing indexed evidence before preview, preserving the 20MiB controls under a 256MiB native pool. Migrate dispatch and retention tests to the preview token contract, keeping write-failure oracles. Note: pre-existing auto-sync /tmp fixture security and installed ARM64 grammar-header failures remain outside this PR; the packed Tree-sitter GLIBCXX_3.4.31 host failure also reproduces on unchanged main. * test(rename): always remove apply fixture (U7) Own the temporary directory from creation in an outer finally so setup and preview assertions cannot bypass cleanup. Keep spy restoration in its inner finally and preserve all write-failure assertions. Address PR #3617 cleanup feedback. * fix(rename): retain targets and config evidence * test(rename): verify approved physical output * test(rename): cover native filesystem matrix * test(rename): align preview contract fixtures --------- Co-authored-by: Gergo Magyar <gergomagyar0@gmail.com> |

fix(query): send hub content once across process_symbols rows (#3356)
* fix(query): send hub content once across process_symbols rows
With include_content, a symbol in several execution flows carried its
full source text on every (id, process_id) row. Keep content on the
first row for each symbol id and omit it from later rows. Membership
fields, is_entry_point, and symbol_count are unchanged.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(query): point agents to the content row and lock the dedup in tests
The query tool text now says content is kept once per symbol id across
the whole process_symbols array, possibly under a different process_id,
and names context({uid, include_content: true}) as the fallback.
Tests: the integration suite asserts func:validate has two rows with
content on exactly one. Unit tests cover a later entry-point row that
is flagged and stripped, a hub in three processes, and that the shaper
does not mutate its input.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(query): state the content-once rule on include_content and in the query hint
The query tool's include_content property now says content is sent once
per symbol id, on its first process_symbols row, and that
context({uid: "<id>", include_content: true}) returns it for any row.
When a query asked for content, the Next hint adds that same fallback;
without include_content the hint is unchanged. The example call now
uses the "<id>" placeholder style used elsewhere in the tool text.
Tests: pin the property sentence, check the hint with and without
include_content, and cover a max_symbols slice that moves the content
row to a later process and a first row that is also the entry point.

fix(group): make degraded links, sync warnings and UID-only impact actually work (#3113)
* feat(group-surface): impact selector pass-through + degraded links + sync hygiene
- @group impact forwards target_uid/file_path/kind through service port
and cross-impact impactParams (was dead-wired: params accepted at MCP
boundary then dropped at validation).
- crossLinks with unresolved provider symbols carry degraded: true,
derived at the persistence boundary after merge/dedupe; sync reports
'degraded links: N' and per-repo extraction failures instead of
swallowing them; bridge write failures surface as sync warnings;
contracts.json passes through dedupeContracts.
- Absolute-URL branch restores %7B/%7D around {param} after URL parsing.
- tests: consumer matrix + wildcard folding + degraded pins (261 new);
SCHEMA_BUMP pin 47 -> 48 (wildcardImports cache shape); sync.ts NUL
byte rewritten as text escape (no longer binary to git).
Co-Authored-By: Claude <noreply@anthropic.com>
* fix(group): impact selector pass-through, degraded links, sync failure hygiene
- @group impact forwards target_uid/file_path/kind through the service
port into cross-impact impactParams. These were accepted at the MCP
boundary and then dropped in validation — a dead wire: disambiguating
an ambiguous impact target never actually reached the per-member impact.
- Cross-links whose provider endpoint never resolves to a graph symbol are
marked degraded: true at the single persistence boundary (post
merge/dedupe, before re-export), counted as SyncResult.degradedLinks,
and surfaced by the sync summary ('degraded links: N') — the remedy
(re-analyze the provider repo) is documented on the field.
- Sync failure hygiene: a repo whose per-repo extraction throws records
its reason in SyncResult.failedRepos (still lands in missingRepos, so
downstream semantics are unchanged) instead of the old silent swallow
that could persist half a repo's contracts; operator warnings
accumulate in SyncResult.warnings.
Tests: cross-impact selector threading, degraded-link marking, per-repo
failure reporting.
* style: prettier
* fix(group): make degraded links, sync warnings and UID-only impact actually work
The three fixes this branch claims were wired at the type and payload level
but never at the boundary that produces the values:
- `degraded` was only ever cleared by the exported `dedupeCrossLinks`, which
the sync path does not use, so `degradedLinks` was always 0. Derivation now
lives in one exported `applyDegradedFlag` that both the sync finalize and
the post-merge re-derivation call.
- The bridge-write catch logged an operator warning and dropped it, leaving
`warnings` permanently `[]`.
- `@group impact` rejected a UID-only call before it parsed `target_uid`, so
the documented "re-call with target_uid" disambiguation loop was
unreachable in group mode even though the selectors were forwarded.
- `failedRepos[].repo` reported the registry display name while the repo
landed in `unreadableRepos` under its group path, so the two lists could
not be joined; the JSDoc also pointed at the wrong list.
- Restored the truncated `READ THE RESULT:` heading in the group_sync tool
description and documented degradedLinks / failedRepos / warnings.
Tests pin each value at the boundary that produces it, including the exact
group_sync wire shape, which previously omitted all three new fields.

fix(group): stop reporting what could not be measured as a measurement of zero (#3012)
* fix: surface unreadable group indexes and escape raw NUL bytes in source Two independent diagnostics failures, both of which turn a real error into a confident, benign-looking answer. **Unreadable member repos (#3011).** `syncGroup` wrapped `initLbug` plus all contract extraction for each member in a bare `catch {}` that pushed the repo onto `missingRepos` and discarded the error. A LadybugDB storage-version mismatch therefore surfaced as "repo not found", `group sync` printed `0 contracts, 0 cross-links` and exited 0, and the existing contracts.json was overwritten with an empty registry. The two states need different answers from the operator — a missing repo must be indexed, an unreadable one is usually version skew or a lock — so they are now separate: - the caught error is logged with the repo, group path and lbug path - `unreadableRepos` is tracked alongside `missingRepos` on `SyncResult`, persisted (optionally, so older registries still parse) on `ContractRegistry`, and threaded through `GroupService` sync/status - `group sync` reports both before the cascade counts, since an unread repo is the likely explanation for a small or empty count - `group status` reports unreadable repos separately; calling them "missing" actively misdescribed them - when EVERY configured repo fails to open, the write is skipped: an extraction that read nothing is not evidence the group has no contracts, and replacing a good registry with an empty one loses data while reporting success **Raw NUL bytes (#3010).** `sync.ts` and `free-call-fallback.ts` each used a NUL as a join delimiter, written as a literal 0x00 instead of `\0`. Identical at runtime, but it makes the file test as binary: `file(1)` reports `data`, ugrep returns empty with exit 1 — indistinguishable from "no match", with no message — and BSD grep replaces matching lines with "Binary file ... matches". A search that should hit comes back as a confident "not present". Both now use the escape, and a unit test fails on any raw control byte in src/ so it cannot silently return. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(hygiene): guard every tracked source file against a raw NUL, not just src/ The guard added with the NUL escapes only scanned gitnexus/src for .ts/.tsx. Neither prior recurrence of this defect in this repo was in that scope: |

* fix(mcp): stabilize api_impact response shape for same-URL multi-verb routes After #2302 made Route identity method-aware, a same URL exposes one Route node per HTTP verb, so a bare-URL api_impact lookup could silently flip from a direct route object to the wrapped { routes, total } envelope. Surface each route's `method` (via the shared fetch) so multi-verb results are distinguishable, and add an optional `method` selector that narrows a multi-verb URL/file to one verb and forces the singular shape. A verb that matches no route returns a clear error. Document the match-count contract in the tool schema. Refs #2308 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(mcp): cover same-URL multi-verb api_impact contract Regression coverage for #2308: bare-URL and bare-file lookups of a same-URL GET+POST pair return the wrapped form with distinct per-route methods; the method selector collapses to the singular shape (case-insensitively); an unmatched verb returns a verb-not-found error; and verbless routes surface a null method. Refs #2308 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(review): apply autofix feedback - tools.ts: correct api_impact contract docs — `method` narrows to one verb but the singular shape only holds when exactly one route remains after filtering (substring route/file matches can still wrap); cover file lookups; enumerate verbs. - local-backend.ts: surface `method` in route_map and shape_check output (the shared fetch already returns it; agents discover verbs there before api_impact). - local-backend.ts: compute routeCountByHandler from the unfiltered match so a method-scoped api_impact still flags a multi-verb handler's partial middleware. - tests: add file+method and verbless-exclusion cases; assert unconditionally via toMatchObject; lowercase the verb-not-found input to exercise error uppercasing. Refs #2308 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(mcp): treat wildcard '*' routes as matching any api_impact method selector (#2308) Method-agnostic routes (Django function views) persist with Route method '*', not null. The api_impact method selector used exact verb equality, so '*' routes were excluded and api_impact({route, method:'POST'}) falsely reported 'No routes found' for a route that handles every verb. Treat '*' as matching any requested verb, and correct the comment + tool-description strings that wrongly grouped Django wildcards with null/verbless routes. * fix(mcp): harden api_impact method input against non-string and empty values (#2308) The MCP envelope is not schema-validated, so a non-string `method` reached `.toUpperCase()` and threw a TypeError. Widen the param to `unknown` and guard it with a typeof check that returns a structured error (mirroring the resolveAliasString pattern from #2175), and collapse empty/whitespace verbs to no selector. * fix(mcp): distinguish url-not-found from verb-not-found in api_impact error (#2308) The verb-not-found error appended 'with method "X"' even when the URL/file itself did not exist, implying the URL exists with other verbs. Gate the verb clause on matched.length > 0 so a non-existent URL/file gets the plain message. * fix(mcp): clarify api_impact middlewareNote wording for verbless siblings (#2308) The partial-middleware note claimed 'other methods in this handler' even when the co-located sibling is a verbless (null) route rather than another HTTP verb. Refer to 'other route exports' instead, which covers both cases. * docs(mcp): document and test the method field on route_map and shape_check (#2308) The shared fetchRoutesWithConsumers change surfaced a method key on route_map and shape_check responses too, but their tool descriptions never mentioned it and no test covered it. Document the field on both descriptions and add unit tests asserting it (shape_check rows carry responseKeys + a consumer so they survive shape_check's keys-and-consumers filter). * test(mcp): cover middlewareDetection 'partial' survival under a method filter (#2308) The diff's core behavioral line counts verbs-per-handler from the unfiltered match set so a method-scoped query still flags a multi-verb handler's partial middleware, but no test exercised it (every verbRow hardcoded middleware:null). Add a middleware param to verbRow and a test that fails if the count is taken from the post-filter set instead. Verified via mutation: matched->routes fails it. * test(mcp): add live-LadybugDB integration coverage for route method round-trip (#2308) The new n.method query column was only unit-mocked. Add a self-contained integration suite that seeds GET+POST /api/orders and a method-agnostic '*' Django route, then asserts api_impact surfaces method, narrows by verb, and matches the '*' route end-to-end (the U1 fix), plus route_map surfacing. Own seed + no FTS so it neither perturbs api-impact-e2e nor silently skips. * refactor(mcp): type the api_impact response shape instead of Promise<any> (#2308) Replace apiImpact's Promise<any> with an explicit ApiImpactResult union (single route | wrapped { routes, total } | { error }) and a typed ApiImpactRoute. The results.map is annotated so the response builder is checked against the declared shape. Behavior unchanged; sibling MCP methods keep their Promise<any> convention. * fix(mcp): express the route-or-file requirement in the api_impact schema (#2308) The inputSchema left route/file as bare optionals, so the 'at least one of route/file' rule the handler enforces was invisible to clients. Add an optional anyOf to ToolDefinition (forwarded verbatim by the ListTools handler) and an anyOf:[{required:[route]},{required:[file]}] on api_impact. Matches runtime (both allowed, route wins); 'at least one' not 'exactly one'. --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

fix(mcp): tolerate adapter-materialized line:0 in impact callgraph mode (#2279) (#2283)
* fix(mcp): tolerate adapter-materialized line:0 in impact callgraph mode (#2279) Some MCP client/agent adapters serialize an omitted optional numeric field as `0` rather than dropping it, so callgraph `impact` calls arrive carrying a spurious `line: 0`. `line` is a PDG-only statement anchor and is meaningless on the callgraph path, so the backend rejected the call ("'line' is only supported with mode:'pdg'") and strict clients rejected it client-side against the advertised `minimum: 1`. Treat a literal `line: 0` as omitted in `_impactImpl` when mode !== 'pdg' and let the normal symbol→symbol BFS run. The coercion is deliberately narrow: only the literal 0, only on the callgraph path. A genuine positive `line` on callgraph still errors (real mode mistake), negative/ fractional values still error, and pdg mode is untouched — `line: 0` there is still rejected (there is no 1-based source line 0 to anchor on). Regression tests pin the full matrix: callgraph + line:0 runs the BFS and is byte-identical to omitting line; pdg + line:0 still errors; positive line on callgraph still errors. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(mcp): log swallowed best-effort query degradations at warn, not error `logQueryError` is the shared handler for query failures that every caller catches and degrades past with a safe fallback (the operation still returns a result). It logged all of them at `logger.error` (level 50) — the same severity as fatal failures — so a gracefully-handled degradation raised a false alarm and drowned genuine errors. This surfaced as an ERROR-level log firing during a passing unit test that intentionally injects a slice-callees query failure to verify the degrade path. Make the severity match reality: - benign missing optional table/label/column (a repo analyzed without processes/communities, or a pre-v3 PDG index lacking the `calleeIds` column — a query that fails on every pdg-downstream impact for such an index) → debug, the normal-configuration case. - any other swallowed failure → warn (handled degradation, still observable). - error is reserved for failures that actually abort an operation, which log directly rather than through this helper. Also fix the sibling bm25/FTS fallback, which logged its swallowed "FTS indexes may not exist" degradation at error while its own import-failure fallback already used warn. The slice-callees degradation test now captures the log and asserts it lands at warn (40), not error (50), pinning the severity against regression. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(mcp): relax impact `line` schema minimum to 0 for adapter compatibility (#2279) Strict MCP clients/agents validate against the advertised input schema and reject a request before sending it. With `line` declaring `minimum: 1`, a client that materializes the omitted optional `line` as `0` rejects a perfectly valid callgraph impact call client-side — so the backend tolerance added in the previous commit never gets a chance to run. Lower the advertised `line.minimum` to 0 and document that 0 (or omission) means "no statement anchor" while mode:'pdg' still requires a positive line. The advertised schema is advisory (the backend self-validates and is the real gate), so this cannot loosen any enforced contract — it only stops strict clients from pre-rejecting `line: 0`. Negative lines are still rejected at the client boundary. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(review): apply autofix feedback Code-review autofix pass on the #2279 branch: - Replace a newly-introduced `mode as any` cast in the #2279 it.each with the narrow `mode as 'callgraph' | undefined` (strict-typing-no-any). - Add a degradation test for the new logQueryError benign-missing-table → debug branch (asserts no warn/error record surfaces, i.e. it routed to debug). - Pin the bm25/FTS error→warn severity change with a _captureLogger assertion in the existing #1489 test. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(mcp): make swallowed-failure callers surface degradation; narrow benign-error match (#2283) Tri-review (#2283) found the `error → {debug|warn}` rework reduced telemetry for `logQueryError` callers that do NOT degrade safely, while the docstring over-claimed "every caller degrades to a safe fallback". Address the substance rather than only the log level: - rename apply-edit: track failed writes and return status:'partial' with `failed_files` instead of reporting `status:'success'` when a write was swallowed. A partial rename is no longer indistinguishable from a clean one. - detect_changes: a swallowed symbol/process query failure now sets `partial:true` (rendered by the existing eval-server partial path) so the pre-commit safety gate can't return a false-clean `risk_level:'low'` no-op. - isBenignMissingTableError: scope the `not (defined|found)` arm to a schema object (table/label/rel/column/property), mirroring lbug-adapter's isMissingColumnError. An unscoped "not found" matched operation failures like `rg: not found` / `Symbol not found` and silently demoted them to debug. - logQueryError docstring: state the contract honestly — level reflects telemetry severity, and mutating/safety-critical callers MUST also surface a result-level degradation signal; `warn` alone is not a substitute. - pdg dispatch: pass the normalized `effectiveLine` (not raw params.line) so the validation gate and engine share one source of truth (identity today). Tests: - _captureLogger(level?) lets tests capture below info; the benign-missing-table test now asserts the record IS emitted at debug (20), not merely absent — no longer a vacuous pass if the call were deleted. - new: a non-schema "not found" failure logs at warn (regex-narrowing guard); rename write-failure degrades to status:'partial'+failed_files; line:-1 on the callgraph path still errors (line:0 coercion is narrow); typed the it.each tuple to drop a `mode as` cast. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(mcp): fix impact `line` description contradiction for whole-symbol pdg (#2283) The new `line` schema description said "mode:'pdg' requires a positive line", which contradicted the top-level impact description ("Without 'line', pdg returns whole-symbol inter-procedural reach plus local whole-symbol PDG diagnostics"). A pdg call without a line is a valid (degraded whole-symbol) call, not an error — the old wording could push an agent to avoid valid no-line pdg calls or synthesize line:0 (which then hard-errors). Reword to: omit line for whole-symbol pdg; a positive line anchors a statement slice; literal 0 is tolerated only as an omitted-line compatibility sentinel on the callgraph path and is rejected for mode:'pdg'. Update the schema test to pin the new, non-contradictory wording and assert "requires a positive line" is gone.

feat(group): cross-repo call trace using PDG (#2269)
* refactor(group): extract shared resolveBridgeNeighbors from cross-impact
Lift the uid-filtered consumer<->provider ContractLink join (direction +
queryBridge + row normalization + confidence sort) out of runGroupImpact's
inline Phase-2 block into an exported resolveBridgeNeighbors helper. Behavior
is unchanged for impact; the helper becomes the single shared bridge join so
the upcoming cross-repo trace path never forks its own copy of the neighbor
Cypher. Empty uid sets short-circuit without a DB round-trip.
Adds direct coverage (real bridge via writeBridge/openBridgeDbReadOnly) for
both directions plus the empty-set and unknown-uid edges.
* feat(group): cross-repo trace stitching (groupTrace + runGroupTrace)
Add GroupService.groupTrace and the pure runGroupTrace engine that stitches
per-repo CALLS/HAS_METHOD trace segments across one ContractLink boundary in
the group bridge:
from --(local trace)--> consumer --(ContractLink)--> provider --(local trace)--> to
- Resolves from/to across all members (symbol node id == bridge symbolUid);
same-repo endpoints delegate to a single local trace with no crossing.
- Single boundary crossing (MAX_SUPPORTED_CROSS_DEPTH); deeper crossDepth is
clamped with a note, mirroring cross-impact.
- Discriminated GroupTraceResult union (ok|not_found|ambiguous|error) with
per-hop repo tags, a typed crossings[] entry, and centralized degraded-state
note constants (TRACE_NOTES). No .
- Trace-specific pair query (keeps BOTH crossing endpoints) lives in this
module; the uid-filtered neighbor join (resolveBridgeNeighbors) is reused
where it fits. ensureBridgeReady exported for reuse.
- New GroupToolPort methods (trace/resolveSymbol/pdgFlows) are optional so
existing port mocks keep type-checking; runGroupTrace guards on presence.
PDG enrichment is wired as an opt-in hook (enrichSegment) — the port method is
stubbed until U4. Covered by unit tests over a real bridge + mocked port.
* feat(group): route trace tool to groupTrace on @group syntax
Wire the cross-repo trace through the existing @group dispatch:
- callTool routes trace with an @-prefixed repo to callToolAtGroupRepo, which
forwards from/to/uid/file/maxDepth/includeTests plus the experimental
pdg/crossDepth flags to GroupService.groupTrace. Member path in @group/path
is advisory for trace (resolution is whole-group).
- Port gains trace/resolveSymbol/pdgFlows adapters. resolveSymbolForGroup wraps
the shared resolveSymbolCandidates so groupTrace can locate the member repo
and recover each endpoint node id (== bridge symbolUid). pdgFlowsForGroup is
a degraded stub here (call-level only); U4 implements the REACHING_DEF walk.
- trace tool schema documents the @group entry point, pdg, and crossDepth.
Single-repo trace is untouched. Covered by dispatch-routing tests (@group ->
groupTrace, non-group stays local) and tool-schema assertions.
* feat(group): opt-in PDG data-flow enrichment for cross-repo trace
Implement _pdgFlowsForGroupImpl: the real REACHING_DEF anchor walk that backs
the port pdgFlows adapter (replacing the U3 call-level stub). When pdg:true and
the segment repo has a flows PDG layer, the boundary-adjacent segments carry
their intra-procedural def->use hops:
- Anchors by the boundary symbol UID (precise; avoids the by-name ambiguity the
resolveBlockAnchor path can hit), then reuses the same span-anchored,
bind-param-only flows query as pdg_query (BasicBlock id-prefix + [start+1,
end+1] line window; no rel-property index, so the anchor IS the bound).
- Stays intra-procedural: data flow never crosses the repo boundary.
- pdgStampForMode probe: false -> available:false (degrade with note); the
trace stays ok. Any query failure is swallowed (enrichment is auxiliary).
Covered by runGroupTrace enrichment tests: dataFlow attached on opt-in,
degraded note when no layer, and no pdgFlows call when pdg is omitted.
* test(group): evaluation-first cross-repo trace e2e (two real indexes)
End-to-end gate for the cross-repo trace: stands up two real LadybugDB indexes
(consumer 'frontend' + provider 'backend'), a real ContractLink bridge, and a
real LocalBackend with both repos registered, then drives the public
callTool('trace', { repo: '@grp', pdg: true }) and asserts:
- the stitched checkout -> callUsers -(CONTRACT_LINK)-> handleUsers -> getUsers
path, each hop tagged with its member repo
- real REACHING_DEF data-flow enrichment of the consumer segment (userId)
- a degraded 'No PDG layer in app/backend' note (provider has no PDG layer)
- single-repo trace against one member is unchanged (no crossings)
Hand-persists the minimal real graph (deterministic; a full two-repo analyze is
heavier than this gate needs) and exercises real Cypher across
resolveSymbolCandidates, _traceImpl, the bridge pair query, and
_pdgFlowsForGroupImpl. Windows-skipped (describeReopen) and registered in the
cross-platform native-lbug set.
Scoped to a single @group call: opening bridge.lbug read-only a SECOND time in
one process currently fails (shared bridge open/close lifecycle, also affects
impact @group) — the pdg-omitted/clamp variants are unit-covered.
* docs(group): document cross-repo trace + PDG enrichment
ARCHITECTURE.md: trace is now group-aware; describe the @group cross-repo
stitch over a single ContractLink boundary (CONTRACT_LINK hop, crossings[],
crossDepth clamp), the opt-in experimental PDG REACHING_DEF enrichment of
boundary-adjacent segments, the symbolUid-grain join between the two stores,
and the deferred full cross-program (SDG-like) data flow. PIPELINE.md: add the
cross-trace consumer of the bridge with its pair-query rationale.
Does not touch gitnexus/CHANGELOG.md (release-owned).
* fix(review): apply autofix feedback
Apply safe_auto findings from ce-code-review (run 20260622-094243):
- local-backend.ts: drop (r: any) in _pdgFlowsForGroupImpl row map; coerce
hop line via Number() so a nullish LadybugDB cell can't surface NaN.
- tools.ts: advertise the forwarded param in the trace schema and add
crossDepth maximum:10 (schema now matches what groupTrace reads).
- cross-trace.ts: parallelize per-member resolveSymbol/resolveRepo with
order-preserving Promise.all (matches groupContext/groupQuery); add a note
when pdg:true is passed to a same-repo trace (PDG only enriches at a
cross-repo boundary).
- tests: remove / tighten (no-any rule).
Residual gated_auto/manual findings (unbounded crossing query + loop,
whole-file PDG widening on absent span, error-vs-no_path masking, top-level
try/catch parity, helper dedupe, branch-coverage gaps) are recorded in the run
artifact for the PR body.
* fix(group): skip CHECKPOINT on read-only bridge close so it can reopen
Root cause of the in-process bridge.lbug reopen failure (which broke repeated
@group impact/trace calls in a long-lived MCP server): closeBridgeDb issued
CHECKPOINT on EVERY handle, including read-only ones. A CHECKPOINT on a
read-only connection has nothing to flush but leaves a WAL/shadow lock artifact
that makes the next read-only open of the same path fail (openBridgeDbReadOnly
returns null -> 'Could not open bridge.lbug read-only'). Reproduced: open ->
query -> closeBridgeDb -> open again returned null only when the close ran
CHECKPOINT; a non-checkpoint close reopened fine, and the raw native
open/close cycle was never the problem.
Fix: tag read-only handles (BridgeHandle._readOnly, set by openBridgeDbReadOnly)
and skip CHECKPOINT for them in closeBridgeDb. Writable handles are unchanged
(they still flush before close). This is the shared bridge-db close path, so
impact @group benefits identically.
- Regression test in bridge-db.test.ts: open/query/close/open/query/open in one
process now succeeds.
- Re-enabled the second @group call in cross-trace-e2e.test.ts (was scoped to a
single call for this very limitation).
* fix(group): bring bridge-db close to parity with the core adapter safeClose
The bridge open/close cycle was less robust than the main graph DB's: closeBridgeDb
closed the connection/database but skipped the post-close steps the core adapter's
safeClose performs, so a rapid in-process reopen could race the OS handle release
(Windows) or an orphaned WAL sidecar. That gap is why the close-then-reopen tests
had to skip Windows.
closeBridgeDb now mirrors safeClose after closing the handle:
- waitForWindowsHandleRelease(dbPath): probe the file (+ .wal) until the residual
Windows lock clears, so the next open does not race (warns if the budget is
exhausted, matching the core adapter).
- finalizeLbugSidecarsAfterClose(dbPath): quarantine an orphaned WAL (shadow
missing) so the next open replays a consistent file.
Both helpers are the same ones safeClose uses (Windows-proven via the core adapter
CI), and the bridge read open already retries transient locks. Combined with the
read-only CHECKPOINT skip, the bridge reopen is now robust on every platform, so
the close-then-reopen tests run on all platforms (Windows CI exercises them via the
cross-platform subset). No write-path behavior change; Linux/macOS unaffected.
* fix(group): bound cross-repo crossing fan-out (LIMIT + segment memoization)
Address the top review residual: the bridge crossing query was unbounded and the
crossing-selection loop could run an O(2*N) sequential trace-BFS over every
ContractLink between a repo pair.
- CY_CROSSINGS_BETWEEN now ORDERs BY confidence DESC and LIMITs to
MAX_CROSSINGS_TO_TRY + 1; listCrossingsBetween slices to the cap and reports
truncation. Exceeding the cap surfaces a note (no silent truncation), keeping
the highest-confidence crossings. Aligns with the repo's anchored+LIMIT-bounded
query discipline (LadybugDB has no rel-property index).
- The home-repo segment (from -> consumer) depends only on the consumer uid and
the target-repo segment (provider -> to) only on the provider uid, so each is
memoized by that uid. Many crossings sharing a consumer/provider (one client
call linked to several providers) now cost one trace per distinct endpoint
instead of one per crossing. A consumer whose segment already failed is skipped
for every later crossing that shares it.
Test: two links sharing a consumer (first provider unreachable, second reachable)
assert the from->consumer segment is traced exactly once and the second crossing
wins.
* fix(group): restore Windows skip for bridge reopen tests; drop ineffective close-side probe
The previous commit flipped the bridge close-then-reopen tests to run on Windows,
betting that a close-side waitForWindowsHandleRelease + finalizeLbugSidecarsAfterClose
probe (mirroring the core adapter safeClose) would make the in-process reopen work
there. Windows CI proved otherwise: 4 writeBridge->openBridgeDbReadOnly tests fail
('expected null not to be null' — the read open returns null). The writable-close ->
read-open handoff plus writeBridge's atomic sidecar rename does not release the OS
file handle before the read open races, and the existing open-side LBUG_OPEN_RETRY
only retries lock-pattern errors, not the post-rename sidecar database-id mismatch.
macOS passes; the core adapter's own reopen also passes — this is bridge+Windows
specific.
- Revert itLbugReopen to the Windows skip (the pre-existing, correct state).
- Remove the close-side probe + finalize from closeBridgeDb: it did NOT close the
Windows gap, and reviewers flagged it for hot-path latency (finalize ran on every
close, all platforms) and safeClose duplication.
- KEEP the load-bearing fix — skipping CHECKPOINT on read-only handles — which fixed
the reproduced Linux/macOS in-process reopen artifact (the real bug).
Net: Linux/macOS repeated @group impact/trace works in-process; Windows in-process
bridge reopen remains a documented limitation (unchanged from before this PR).
* fix(group): surface degraded members + cap truncation; honest crossDepth schema
Address the cross-engine-corroborated tri-review findings (Codex + Claude):
- resolveAcrossMembers / runGroupTrace now track member repos that could NOT be
queried (resolveRepo or resolveSymbol threw) and, when the result is not_found,
attach a degraded-member note. A transient/corrupt member DB is no longer
silently reported as a clean 'symbol absent' not_found. (Codex B1+B3 + ce-reliability.)
- The cross-repo not_found now carries a programmatic truncated:true flag (and a
clearer suggestion) when the MAX_CROSSINGS_TO_TRY cap was hit, so a consumer can
distinguish 'no path' from 'cap may have hidden a connecting ContractLink'.
(Codex B3 + ce-adversarial + ce-api-contract.)
- trace tool schema: crossDepth maximum 10 -> 1 to match the implementation's
single-hop clamp (the schema previously advertised an unsupported 2-10 range).
(ce-api-contract, conf 100.)
Test: a member whose resolveSymbol throws yields not_found WITH a degraded note
naming the unreachable repo (if-free responder map).
* docs(group): clarify trace @group/memberPath is advisory (resolves all members)
Tri-review (Codex ce, conf 100) caught a doc/impl inconsistency: ARCHITECTURE.md
lumped trace with query/context/impact as honoring @group/memberPath member
scoping, but cross-repo trace resolves from/to across ALL members (the member
path is advisory). Clarify the behavior and point to from_uid/to_uid for
disambiguating same-named symbols across members.
* feat(group): file-level boundary fallback so cross-repo trace works on HTTP contracts
Benchmark (bench/cross-repo-trace/) running the REAL pipeline (runFullAnalysis
--pdg -> real syncGroup -> trace @group) found that cross-repo trace returned
not_found for real HTTP links even though sync built the correct ContractLinks:
HTTP (and other source-scan) contracts hardcode symbolUid:'' (http-route-extractor),
and both cross-trace AND cross-impact join crossings by Contract.symbolUid, which
never matches an empty uid. (Pre-existing — impact @group has the same gap.)
Fix: when a crossing's symbolUid is empty, fall back to the contract's FILE — if
the user's from/to resolves into the contract file, that endpoint anchors the
boundary. CY_CROSSINGS_BETWEEN now returns consumer/provider filePath; a crossing
is kept if it can be anchored by uid OR file on each side; a fileBoundaryFallback
note flags that the boundary is file-level, not symbol-precise. This makes the
common 'trace from=<calling fn> to=<handler fn>' case work end-to-end (verified:
fetchUsers -> listUsers stitches with a CONTRACT_LINK hop + PDG enrichment, 2/2).
Limits (documented in the bench README + the note): anonymous handlers have no
named target; when several contracts share files the file fallback may attach the
wrong contractId to a correct path. The proper upstream fix is to populate
symbolUid in the HTTP extraction (benefits impact too) — the bench is its gate.
Adds a unit test pinning the empty-symbolUid file-fallback stitch.
* fix(group): resolve HTTP contract symbolUid by containment (fixes cross-repo trace + impact)
Addresses the root cause behind the cross-repo trace file-fallback: HTTP
contracts hardcoded symbolUid:'' (http-route-extractor), so both cross-trace and
cross-impact — which join crossings on Contract.symbolUid — could not traverse
HTTP links. (Also found: the pre-existing graph-assisted resolution queried the
wrong edge, CONTAINS instead of DEFINES, so it never resolved a uid either.)
Now the extractor resolves each detection to a real symbol:
- HttpDetection carries the call-site line (node.ts sets it on every express/
fetch/axios/jquery/nest detection; express also captures the handler arg).
- resolveDetectionSymbol resolves the named handler first, else the innermost
Function/Method whose line span encloses the call (consumer = the function
containing the fetch; provider = the named/inline handler), over the correct
File-[DEFINES]->symbol edge. Base-tolerant (0- vs 1-based startLine).
- Wired into both source-scan and graph-assisted provider/consumer paths.
Verified end-to-end (bench/cross-repo-trace): all 4 contracts now carry real
uids, trace is symbol-precise (GET pair -> http::GET, POST -> http::POST, no
file-fallback note), and impact @group fans out (cross_repo_hits 0 -> 1). The
cross-trace file-level fallback remains as the secondary path for truly
anonymous handlers. Adds 2 containment unit tests; 738 group/integration pass.
Languages other than JS/TS still resolve providers by handler name; their
consumers fall through to the file fallback until their plugins set the line.
* fix(group): extend HTTP symbolUid containment to all languages + nested methods
Completes the symbolUid resolution across every bundled HTTP plugin: Python, Go,
PHP, Kotlin and Java now set the call-site line on their consumer (and Feign/
named) detections, so their HTTP contracts resolve to the containing function
the same way Node/TS already did.
Also generalizes the containment query: it now matches Function/Method/CodeElement
by filePath (UNION ALL) instead of File-[DEFINES]->symbol. The DEFINES edge only
reaches a file's TOP-LEVEL symbols, so methods nested in classes (Java/Kotlin —
File defines the class, the class defines the method) were invisible; matching by
filePath reaches them. Verified against a real index (LadybugDB supports the
UNION); JS/TS still fully symbol-precise (bench 2/2), 709 group tests pass.
Residual is now only the inherent case — a fully anonymous handler with no named
callee — which keeps the cross-trace file-level fallback.
* feat(group): destination trace — follow a consumer to an anonymous handler
Handles the one inherent residual: an anonymous route handler
(`router.get('/x', (req,res) => …)`) has no symbol node at all (the file holds
only a Const + PDG BasicBlocks), so it can never be named as a trace `to`.
Adds a DESTINATION TRACE: omit to/to_uid/to_file on an @group trace and
`trace from=<consumer>` follows the consumer's outgoing HTTP call across the
bridge and reports where it lands — by route + file:line, with a notes[] entry
flagging the handler as anonymous. Implemented as a new branch in runGroupTrace
(p.destination) backed by CY_CROSSINGS_FROM (all ContractLinks leaving the
consumer repo) + stitchToDestination; the provider endpoint is labelled
'<METHOD /path handler>' when its symbolName is a generic token/file basename.
The MCP routing already omitted an absent `to`, so only the schema docs changed.
parseTraceParams now treats a missing `to` as a destination trace instead of an
error. Verified end-to-end: anonymous fixture reports
'app/frontend:fetchUsers -> app/backend:<http::GET::/api/users handler>'; named
fixture lands at the real function. Adds 2 unit tests; 915 group tests pass.
* fix(group): tri-review fixes for cross-repo trace + symbolUid resolution
Two-engine tri-review (Claude swarm+ce + Codex GPT-5.5 swarm+ce+adversarial)
surfaced these; cross-engine-corroborated unless noted.
Correctness (P1, all four lanes): destination trace reported the WRONG endpoint
— an empty-uid consumer made trace(from->from) trivially succeed, so the highest-
confidence same-file crossing won regardless of which call `from` makes.
stitchToDestination now collects ALL connecting crossings, prefers symbol-precise
hits, and returns `ambiguous` (with candidates) when it cannot disambiguate.
Correctness (P1, Codex): resolveDetectionSymbol early-returned null when
d.line==null, blocking NAME resolution for named providers that set no line
(Spring/Go/etc.). Name resolution now runs first; only containment needs a line.
Correctness (P2): resolveContainingSymbol OR-ed `line` and `line-1`, which could
mis-pick a one-line sibling. It now probes the base-correct `line-1` first and
falls back to `line` only if nothing matches.
Correctness (Codex): anonymous Express handlers emitted name:'handler' and could
attach to an unrelated fn literally named `handler`. node.ts now emits name:null
for non-identifier handlers (containment-only).
Robustness: drop the first-symbol-in-file pickSymbolUid guess from the graph
consumer/provider paths (a wrong uid would win the contractId merge); remove the
dead CONTAINS_QUERY fallback (CONTAINS is File->Folder, never a symbol) + the now
-unused pickSymbolUid/handlerName; seed destination notes with degraded-member
notes so a successful trace still surfaces them; providerLabel takes providerUid
so a resolved fn named `handler` is not mislabeled anonymous, and only true file
basenames (known extensions) — not any dotted name — count as anonymous.
API contract: a single-repo trace with no `to` now returns an actionable error
(destination trace is @group-only) instead of "symbol 'undefined' not found".
Maintainability/tests: narrow asLocalTrace per-field (drop as-unknown-as); fix the
PR's lone as-any (vi.mocked); if-free e2e teardown; qualify the bench README.
Adds ambiguous-destination, anonymous-handler-no-false-name, and single-repo-no-to
tests; redirects graph mocks CONTAINS->UNION ALL. 918 group/integration pass.
* fix(group): carry degraded-member notes through SUCCESSFUL group traces
A reviewer (koriyoshi2041, PR #2269) correctly flagged that degraded-member
resolution was surfaced only on not_found, not on a successful ok result. Group
trace resolves names across ALL members, so an ok is 'unique among the members
we could query' — if a member that threw during resolveSymbol also holds from/to,
the real answer could be ambiguous. The destination path already seeded the note
(prior commit); this extends it to the same-repo and cross-repo success paths by
seeding the dispatch notes with degradedNotes([...fromRes.degraded, ...toRes.degraded]).
Adds a regression test: reg-be throws while a same-repo trace succeeds in reg-fe;
the ok result now carries the 'could not be queried' degraded note (app/backend).
* test(bench): cover all implemented cross-repo trace cases in one runner
Replace the single named-handler script with a self-contained verify.mjs that
generates each fixture inline and exercises every implemented end-to-end case
against the real analyze -> sync -> trace/impact pipeline, asserting PASS/FAIL
(exit non-zero on failure). 10 checks across 4 scenarios:
- named handlers: 4/4 symbolUid resolved; symbol-precise GET vs POST crossing
selection; destination trace lands at the named handler.
- anonymous handler: empty symbolUid; destination trace reports it by route with
the anonymous note.
- impact @group fan-out (cross_repo_hits >= 1).
- multi-language (Python Flask + requests): link built, cross-repo trace stitches,
and the file-level boundary fallback is exercised when the provider has no uid.
Ambiguous-destination and degraded-member paths need synthetic inputs the real
analyzer cannot produce, so they stay in the unit suite (documented in the README
+ script header). Removes verify-named.mjs + fixtures-named/ (folded inline).
* test(group): pin destination degraded-success + precise-tier ambiguity
Adds the two regression guards koriyoshi2041 requested on PR #2269 after the
degraded-on-success fix:
- destination trace success with a degraded member: reg-fe resolves from and
follows the link to an anonymous handler while reg-be throws; the ok result
carries the anonymous endpoint AND the 'could not be queried' degraded note, so
the no-to path stays aligned with explicit to traces.
- multiple PRECISE destination hits: one from reaches two consumers with resolved
uids linked to different routes; the result is ambiguous (role: to) with both
route candidates. Distinct from the existing file-level ambiguous test, this
pins the stronger precise tier against a future change silently picking the
highest-confidence destination.
Both already pass against current behavior; 716 group tests pass.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * perf(mcp): bound trace BFS with per-level LIMIT and visited cap The per-level query had no LIMIT and the visited set was uncapped, so a high-fanout hub could materialize an unbounded frontier. Cap per-level rows (interpolated LIMIT — Kuzu does not bind LIMIT) and the total visited set; either cap sets a `truncated` flag so a resulting no_path reports that the search was cut short rather than implying the graph was exhausted. Note: the sibling impact BFS shares the same unbounded pattern; applying the cap there is deferred (out of scope for this PR). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(mcp): clarify trace traverses call + class-member edges trace was advertised as a "shortest call path" but also traverses HAS_METHOD (class→member) containment edges so a class-rooted trace can descend into its methods. Keep that capability (consistent with impact/ context) and make the docs honest: rename EDGE_TYPES→TRAVERSAL_EDGE_TYPES, state the call + class-member traversal in the MCP/CLI/i18n/ARCHITECTURE descriptions, and note each hop's edge type is reported in edges[]. No behavior change. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(mcp): set status:'error' on trace failure responses Every trace return path sets a `status` discriminator except the caught-error path, so a consumer switching on `result.status` saw undefined on failure. Add status:'error' to both the backend trace() catch and the CLI traceCommand catch. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(mcp): return a friendly error for non-string trace from/to A non-string from/to reaching resolveSymbolCandidates surfaced a low-level "x.includes is not a function" via name.includes. Guard the four name/uid params at the top of _traceImpl and return a structured status:'error' with a clear message instead. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(mcp): single row-decode + drop dead field in trace BFS Decode each BFS row once into named locals instead of repeating `(row.x ?? row[N])` across the two parent.set calls and the furthest-tracking. Drop the `type` field from the parent map value (it was written but never read), and rename the internal `deepestInfo` to `lastReached` for accuracy (the output field `furthest` is unchanged). Pure refactor — no behavior change. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(cli): dedicated trace includeTests i18n key + guard coverage `trace|--include-tests` reused the impact help key, so rewording the impact option would silently change trace's help text. Add a dedicated help.option.trace.includeTests key in en + zh-CN and repoint it. Add CLI coverage for the (already symmetric) --from-uid/--to-uid flag-value guard and for --include-tests forwarding. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(mcp): faithful BFS mock + expand trace coverage Fix makeResolveMock: concatenate neighbors across ALL frontier ids (it returned only the first node's, so a multi-node frontier was unmodelled) and key the UID branch on params.uid (the old query-text match never fired). Add coverage: shortest path through the second frontier node (proves the mock fix), confidence floor fallback, HAS_METHOD traversal with a mixed edge-type chain, no_path furthest:null, and from_file disambiguation. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * style(trace): apply root prettier formatting to trace files The root `quality / format` gate (prettier --check, printWidth 100) runs on the full repo and flagged the trace sources/tests (the local config masks it). Reformat to root style — no behavior change; trace + tools suites and tsc stay green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(skills): document the trace tool for AI agents Add `trace` to the GitNexus skill docs so agents reach for it instead of hand-chaining context/impact hops. The guide gains a Tools Reference row and a "shortest path between two symbols" subsection (params, result shape, status/furthest/truncated semantics); the debugging skill gains a "how does A reach B?" pattern row and a trace tool example. Mirrored to the .claude and claude-plugin copies (byte-identical) and the cursor copy (compact style). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(mcp): drop unused trace test fixtures (CodeQL js/unused-local-variable) CodeQL flagged two unused locals in the trace BFS tests: the top-level SYMBOL_C and a SYMBOL_D inside the maxDepth test (both defined, never referenced). Remove them. No behavior change — 58 trace/tools tests stay green.

feat(pdg): control dependence — post-dominators + CDG (Ferrante) [M5 #2085] (#2188)
* feat(pdg): add CDG + POST_DOMINATE edge types (M5 #2085) * feat(pdg): post-dominator tree on reverse CFG (M5 #2085) * feat(pdg): Ferrante control-dependence over the post-dom tree (M5 #2085) * feat(pdg): emitFileCdg + optional POST_DOMINATE debug edges (M5 #2085) * feat(pdg): wire CDG emission in-phase + pdgModeMismatch CDG-cap stamp (M5 #2085) * test(pdg): CDG snapshot + end-to-end pipeline answerability (M5 #2085) * fix(review): apply autofix feedback (M5 #2085) * fix(pdg): label CDG edges by controller arm sense, not edge kind (#2188 F1/F2/F4) Tri-review (with Codex as the independent engine) found the CDG 'T'/'F' label was wrong for the commonest control flow: the M1 TS visitor wires a condition's fall-through FALSE arm as `seq`/`loop-back`, but `branchSense` mapped both to 'T', so guard clauses, if-no-else, and loop `break` got 'T' instead of 'F' (F1, P1). The structural CDG edges were correct; only the label — the AC3 "under what condition does X run?" answer — was wrong. - F1: replace edge-kind `branchSense` with controller-arm-sense `labelFor`. An ambiguous fall-through edge (seq/loop-back) takes the COMPLEMENT of its source block's explicit cond-true/cond-false sibling arm. This correctly handles do/while (loop-back = TRUE arm) and inner-if-in-loop (loop-back = FALSE arm) — the ambiguity a kind→label table cannot resolve. Adds real-parser regression tests (the hand-built tests used a fictional cond-false edge and missed it). - F2: correct the false "sound over-approximation that never drops a real dependence" claim in post-dominators.ts — exit-unreachable regions both drop and invent control dependences (latent for the current TS visitor, which keeps EXIT reverse-reachable). Reframe the exit-less-loop test to characterize, not bless, the degenerate behavior. - F4: make the AC2 property-test reference compute post-dominance INDEPENDENTLY (node-removal reachability, no shared code with post-dominators.ts), so a post-dom direction bug can no longer pass both the impl and the reference. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(ci): root-prettier format + run-analyze pdg stamp gains maxCdgEdgesPerFunction (#2085) Two deterministic CI failures from the M5 CDG work: - quality/format: basicblock-roundtrip.test.ts failed CI's root `prettier --check .` (the pre-commit hook uses the gitnexus-local prettier config, which differs); reformatted with the root config. - tests/ubuntu/coverage: run-analyze.test.ts pinned the resolved RepoMeta.pdg shape (DEFAULTS) and the all-zero cap override without the new maxCdgEdgesPerFunction key (default 5000); added it so resolvePdgConfig toEqual and pdgModeMismatch(DEFAULTS) pass. (The stale-test sweep missed this file in PR #2188 — same trap M2 hit.) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(mcp): add pdg_query tool definition (controls/flows modes) [M6 #2086] * feat(mcp): pdg_query backend — controls (CDG) + flows (REACHING_DEF) + e2e test [M6 #2086] * feat(mcp): document PDG edges + pdg_query (schema, cypher, skill, --pdg-gated ai-context) [M6 #2086] * fix(mcp): correct pdg_query symbol-anchor lower bound + harden inputs [PR #2188 review] Tri-review (Codex + adversarial + correctness lanes) of the M6 pdg_query surface found the symbol-anchor window over-includes a neighbor function's block. The upper bound was widened to the 1-based BasicBlock basis (symEnd+1) but the lower bound was left 0-based, so a block on the line directly above the target function leaked into the result. Shift both bounds +1 ([symStart+1, symEnd+1]) so the window is the function's true block span. Also from the same review: - pdg_query no longer throws on a no-arguments MCP call: the dispatch passes raw `params`, so default it to {} → a clean mode-validation error instead of a TypeError. (`explain` shares this latent pattern — pre-existing follow-up.) - tools.ts: the controls-mode description no longer hard-codes the 'F' branch sense for guards — `if (!ok) return;` rides the predicate's 'T' arm; the guard:true flag is label-agnostic (regex on the dependent block text). Tests: a hand-seeded adjacency regression (verified failing without the lower-bound +1) + a no-arguments validation test. Skill doc updated to document the two-sided [symStart+1, symEnd+1] window. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(mcp): drop always-true anchor conditional in pdg_query [CodeQL #2188] CodeQL alert 756 flagged `...(anchor ? { anchor } : {})` in _pdgQueryImpl as a useless conditional: `anchor` is unconditionally assigned in both the file-path and symbol branches before the return (the not-found/ambiguous/no-layer paths return earlier), so it is always truthy. Drop `| undefined` from the declaration (TypeScript definite-assignment holds across both branches) and emit `anchor` directly. No runtime change — the `anchor` field was already present on every result. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(cli): add hasPdg to the noStats bridge expectation [#2188] The M6 work threaded `hasPdg: options.pdg === true` into the AIContextOptions passed to generateAIContextFiles on the --skills regeneration path, but this test's strict .toEqual expectation predated it (4 keys vs 3 → CI failure). Add `hasPdg: false` (the value on this non---pdg path). The assertion stays strict; the #1477 noStats bridging it guards is unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(cli): collapse generateGitNexusContent params to an options bag [#2188] The function had grown to 9 positional params; reaching `hasPdg` meant passing six `undefined`s (the M6 review's maintainability flag). Collapse params 3-9 (generatedSkills, groupNames, noStats, skipSkills, runnerPath, defaultBranch, hasPdg) into a `GitNexusContentOptions` object with the defaults moved to destructuring. The body is unchanged (same local names); the single production caller and the test calls become self-documenting named fields. Pure refactor — generated AGENTS.md/CLAUDE.md content is byte-identical. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(cfg): skip CDG for exit-unreachable CFGs (unsound post-dominance) [#2188] M5 review P2: computePostDominators roots only at cfg.exitIndex and nothing enforced that EXIT is reachable from every block. For an entry-reachable region that cannot reach EXIT (a non-terminating loop, or a multi-terminal CFG a future visitor might emit) the EXIT-rooted reverse walk degenerates — it both drops real control dependences and invents spurious ones. Add a pure precondition predicate `isExitReachableFromAllBlocks` (co-located with the algorithm it guards) and gate it in emitFileCdg: a CFG that violates it is skipped for CDG (counted as skippedUnsoundFunctions + one onWarn), while its CFG and REACHING_DEF projections — which do not depend on post-dominance — are kept. A CDG-specific gate, not a widening of isEmitSafeCfg, so the blast radius is exactly the unsound CDG. The current TS visitor always satisfies the precondition (every loop gets a structural header→loopExit edge), so CDG output for real fixtures is unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(cfg): bound computeControlDependence materialization (heap parity) [#2188] M5 review P2: unlike computeReachingDefs (maxFacts) and the emit-side edge cap, computeControlDependence materialized the full deduped seen/out before emitFileCdg's per-function cap could trim it — O(edges × post-dom depth) heap for a deeply nested function. Add a `maxEdges` ceiling (default 0 = unbounded) returning {edges, truncated}, mirroring computeReachingDefs's {facts, truncated}. The ceiling is checked before pushing a new unique edge, so `truncated` means a genuine overflow (not merely "reached cap"). emitFileCdg passes a FIXED materialization ceiling (8× the default edge cap) — deliberately NOT derived from the runtime edge cap, because CDG's materialization IS the deduped-edge quantity the cap reports on (deriving it would pre-truncate that set and lose the exact dropped count). A ceiling hit is surfaced via onWarn + the truncated flag — never silent. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(mcp): share resolveBlockAnchor; fix explain's anchor off-by-one [#2188] M6 review P2 (duplication) + the flagged pre-existing _explainImpl correctness follow-up. _pdgQueryImpl and _explainImpl each carried a near-identical symbol↔block anchor resolver that had DRIFTED: pdg_query used the corrected [symStart+1, symEnd+1] window (BasicBlock startLine is 1-based, the symbol span 0-based) while _explainImpl still used [symStart, symEnd] — dropping a taint source on the function's final line AND leaking a neighbor's block on the line directly above. Extract one `resolveBlockAnchor` helper, used by both, that applies the correct window and a single (bare) clause convention (callers compose their own WHERE). This removes ~50 duplicated lines and fixes explain's anchor in one place. A hand-seeded characterization test (taint-explain Block 4) pins both bounds — verified to FAIL on the pre-fix window (it returned the line-10 neighbor instead of the line-15 final-line source). Existing taint-explain + pdg-query suites are unchanged (their fixtures have interior sources/sinks). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(mcp): pdg_query reports "status unknown" when the layer can't be confirmed [#2188] M6 review P3 (Codex): when meta is UNREADABLE and the bounded global existence probe returns zero rows of the edge type, _pdgQueryImpl asserted "no PDG layer" — but a genuinely edge-free layer (all-linear functions) is indistinguishable from a missing one via that probe. Soften only that fallback path to an inconclusive "PDG layer status unknown — was this repo indexed with --pdg?" note. The meta-stamped path (stamp present, cap absent ⇒ layer truly missing) keeps the definitive "no PDG layer" wording. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(mcp): cover pdg_query ambiguous / pagination / Windows-path gaps [#2188] M6 review test-gap follow-ups, all hand-seeded with controlled data: - ambiguous symbol name → status:'ambiguous' + ranked candidates shape (uid/name/filePath/score), never a silent guess; - total/truncated page boundary in both directions (limit below the match count sets truncated with the full total; limit above it omits truncated); - a Windows-style filePath containing ':' resolves and fnLineOf decodes the function-line segment correctly (split-from-right past the drive letter). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(skills): ship gitnexus-pdg-query skill mirrors + add pdg_query to the guide [#2086] M6 bundled pdg_query into this PR, but the skill shipped only in the canonical gitnexus/skills/ root. Mirror it (byte-identical) to the two hand-maintained roots the sibling taint skill uses — .claude/skills/gitnexus/ and the plugin — so Claude Code + plugin users get it too. Also extend the gitnexus-guide tool reference (all 3 copies, now byte-identical): add a `pdg_query` row + a "Control & data dependence" section mirroring the taint/`explain` section, and reconcile the pre-existing drift where only the .claude copy carried the `check` tool row (a real registered tool) — all three now list it. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(architecture): refresh CFG/PDG section for the full M1–M6 stack [#2086] The PR body had deferred the "ARCHITECTURE docs refresh" to #2086; now that M6 ships here, do it: - MCP tools table gains `explain` and `pdg_query` (were absent). - "Optional CFG/PDG emission" was M1-only; rewrite to cover the whole opt-in stack — M1 CFG, M2 REACHING_DEF, M3/M4 taint, M5 CDG (Ferrante over CHK post-dominators, with the exit-unreachable skip), M6 read surface (pdg_query + explain, anchored + LIMIT-bounded, shared resolveBlockAnchor) — and note the no-Function→BasicBlock-edge join. - LadybugDB schema notes the `--pdg` additions: the `BasicBlock` node table and the CFG/REACHING_DEF/CDG/TAINTED/SANITIZES/TAINT_PATH relation types, kept out of the default VALID_RELATION_TYPES / web schema.

fix(mcp): rename query/cypher params so Claude Code can call them (#2186)
* fix(mcp): advertise search_query/statement params for query/cypher tools (#2175) Claude Code drops a tool-call argument named exactly 'query', making the query and cypher tools unusable from it. Rename the advertised required parameters to search_query and statement so the client transmits them. Handler-side backward-compat for the legacy 'query' key follows in the next commit. * fix(mcp): accept search_query/statement with legacy query fallback (#2175) Resolve the new advertised param names in the backend while still accepting the legacy 'query' key, so curl/HTTP, other MCP clients, the CLI, the group path, and the internal executeCypher() all keep working. Alias is normalized once at the callTool chokepoint (covers group-forward + search alias); query() and cypher() dual-read defensively. New name wins when both are supplied. Updates the required-error message and adds dual-accept unit + integration coverage. * fix(cli): pass canonical search_query/statement params to query/cypher tools (#2175) Stop the CLI from depending on the deprecated 'query' alias. No user-facing change — the positional args are unchanged and the backend accepts both keys. * fix(mcp): generators advertise search_query in query() examples (#2175) Update the three doc/example generators (ai-context AGENTS/CLAUDE block, skill-gen community skills, resources repo hint) so future analyze runs emit query({search_query: ...}) — the param name Claude Code actually transmits. Tests assert the new form is present and the legacy query({query: form is absent (the #2059 generator-test pattern). * docs(mcp): advertise search_query/statement in skill & guidance examples (#2175) Sync the committed agent-facing docs to the renamed params so a Claude Code agent following them emits the transmittable key: AGENTS.md/CLAUDE.md gitnexus block, the canonical gitnexus/skills/* source and its installed/plugin/cursor mirrors, and the README examples. Scoped rewrite of the two call prefixes only (query({query: -> search_query, cypher({query: -> statement). * style(mcp): prettier line-wrap for #2175 alias-resolution edits * fix(review): uniform search_query precedence + cypher empty guard (#2175) Code-review findings (correctness/adversarial/api-contract/maintainability consensus): - Group-mode query inverted the 'new name wins' rule: the callTool chokepoint backfilled params.query only when empty and the @group-forward read params.query directly, so a both-keys (or whitespace-legacy) group call let the legacy value win — unlike the local path. Replace the hidden param mutation with a self-contained 'search_query ?? query' resolve at the group-forward; precedence is now uniformly new-wins at every consumer site. - cypher() now returns the same friendly required-param error as query() when neither statement nor query is supplied, instead of a raw DB prepare error. - Document the legacy alias as permanent (third-party clients may send query=). Adds group-forward alias tests (both-keys + legacy-only), empty/whitespace search_query, the search-alias path, and the cypher empty-statement guard. * fix(review): non-string alias safety + drop stale chokepoint comment (#2175) Tri-review findings (correctness/adversarial/security + maintainability): - Non-string statement/search_query/query (the MCP envelope is not schema-validated) hit .trim() and threw TypeError to the server boundary instead of a friendly required-param error. Introduce resolveAliasString() (new name wins; non-string -> undefined) used by query(), cypher(), and the group-forward, so all three return the structured error. Empirically verified (123 ?? '' -> 123, (123).trim() throws) — this overrides a critic refutation that mis-read ?? as a string coercion. - Remove the stale query() comment claiming alias resolution happens at a callTool chokepoint; that mutation was removed earlier in this PR — each site resolves the alias itself. - Document GroupToolPort.query's intentionally-narrower required type vs the wider LocalBackend impl. Adds non-string and empty-new-key precedence tests. * fix(mcp): alias falls back to legacy value when new key is blank (#2175) PR #2186 review finding: resolveAliasString used `canonical ?? legacy` (nullish), so an explicitly empty/whitespace new-name value (e.g. {search_query:'', query:'real'}) won and was rejected — discarding a valid legacy value, contradicting the 'new name wins when both supplied' intent. Resolve to the first NON-BLANK string instead (new preferred when it carries a real value, else legacy). Covers query(), cypher(), and the group-forward (all route through the helper); non-string still resolves to a friendly error. Flips the presence-based test and adds whitespace/cypher/group fallback cases. * fix(mcp): drop legacy "query" mention from query/cypher schema descriptions (#2175) PR #2186 review finding: the search_query/statement inputSchema descriptions named the legacy "query" key — the exact arg Claude Code drops — and description text is read by an LLM choosing arguments, weakly nudging it to send "query". Trim the descriptions to their clean form and move the legacy-alias note to a code comment next to the schema (preserved for maintainers / non-CC clients). properties/required unchanged (no `query`). |

feat(taint): intra-procedural taint analysis (#2083) (#2164)
* feat(taint): harvest occurrence-tagged call/member sites on StatementFacts (#2083 U1) Worker-side site harvest in TsHarvester: call/new/member-read records with dotted callee paths, receiver slots, per-argument occurrence tagging with nested-site links, per-declarator resultDefs, spread/template/require-literal markers. hasTaintSafeSites validation seam. The pdg parse-cache chunk-key namespace is versioned (pdg:1 -> pdg:2) instead of a global SCHEMA_BUMP so flag-off users keep warm caches; bench fingerprints re-baselined for the three call-bearing scenarios (straight-line/dense-bindings byte-unchanged). * feat(taint): built-in TS/JS source/sink/sanitizer model + site matcher (#2083 U2) Typed spec (kind taxonomy; sanitizers carry neutralizes-kinds), the canonical Express/Node model, and matchFunctionSites: ESM alias/namespace + require- literal callee resolution, bare-name fallback restricted to true globals, sanitizers module-or-global only (never user-shadowable by name), spread/ template arg-position rules, deterministic taintModelVersion. * feat(taint): pure intra-procedural taint propagation engine (#2083 U3) Two-rule model (statement-local + du-fact worklist) with per-taint neutralized-kind exclusion sets: sanitizers exclude only the sink kinds they neutralize (escape(req.body) suppresses res.send but still fires db.query; exec(path.basename(t)) fires), intersection-over-paths so a bypass occurrence keeps the taint live, kill locality on resultDefs, propagate-through args+receiver with viaCall hops, one path per finding, deterministic caps, coverage-gap statuses. Test-first: 38 scenarios on real harvested CFGs. * feat(taint): thread taint caps + model version through pdg config/meta (#2083 U5) resolvePdgConfig gains maxTaintFindingsPerFunction (200), maxTaintHops (32), and the taintModelVersion digest; RepoMeta.pdg + RunScopeResolutionInput surfaces added. The key-union comparator trips full writeback on M2->M3 upgrade and on model-version change without --force (mode-flip tested). No CLI flags or rc keys (programmatic parity with the other caps). * feat(taint): in-phase taint emit with sparse TAINTED/SANITIZES edges (#2083 U4) run.ts pdg window: match-first fast path (solver only when a function has both a matched source and sink) -> computeReachingDefs with the shared RD fact derivation -> computeTaintFlows -> per-finding TAINTED (versioned hop-encoded reason via the shared path codec, statement-level occurrence identity) + per-kill SANITIZES, dedup-before-budget, truncate-and-warn. All emit counters surfaced (aggregate warn for gaps/drops, debug for volume); PROF gains taint=. Flag-off golden untouched. * feat(mcp): explain tool for persisted taint findings (#2083 U6) Anchorless calls enumerate the sparse TAINTED table (bounded, deterministic, limit-clamped); anchored calls (file or symbol via resolveSymbolCandidates) return full decoded hop detail. sinkKind rides a version-1 codec header (1;<kind>|hops — no other persisted channel exists; U4/U6 ship together). RepoMeta.pdg probe yields a no-taint-layer note instead of an error. TAINTED/SANITIZES pinned OUT of VALID_RELATION_TYPES (KTD9a negative- membership tests); generators + canonical skill docs + mirrors updated. * test(taint): acceptance fixture battery, snapshots, and bench gates (#2083 U7) pdg-repo taint-cases fixtures complete the six plan shapes; committed findings/kills snapshot via a shared pure-path harness that also feeds the AE2 exact-equality assertion (stored TAINTED == pure-path findings, the no-explosion gate). New taint-dense bench scenario with four --check gates: per-function findings pinned AT the cap, absolute reason-byte + site-bytes disk ceilings (the load-bearing R10 gate), zero-match pass < 0.5x match- dense, N-linearity. Pre-existing scenario baselines untouched. * refactor(taint): share one pointKey helper across propagate + emit (#2083 review) Extract pointKey(ProgramPoint) to cfg/reaching-defs.ts (colon-separated, matching the codebase block:stmt id convention) and import it in both propagate.ts and emit.ts, replacing the two divergent locals (':' vs '.'). Edge-id material now uses the colon form; ids are in-memory only and no test asserts the pointKey segment shape. * fix(taint): discriminate taint state by source occurrence (#2083 review) Two distinct sources flowing into one variable at one def point no longer collapse to a single TAINTED edge: the taint-state key gains a root source-occurrence discriminator ({point, siteIndex} — the same fields recordFinding's identity uses, excluding kind). Def->use fact lookup keys on the source-independent (binding, def-point) portion. Same-source multi-path flows still share one state so their exclusion sets intersect (the raw arm soundly wins); termination holds (finite keys, monotone shrink, no cross-source ping-pong). Restores the KTD6 identity contract. * fix(mcp): route dotted symbol names in explain to symbol resolution (#2083 review) The fileish classifier matched any dotted name (UserController.create) as a file via its extension-like suffix, so symbol resolution never ran and the tool returned a silent empty file-anchored result. Tighten the classifier to require a path separator or a real source extension (derived from the resolver's EXTENSIONS list, multi-language), so dotted/bare names route to resolveSymbolCandidates (found / ambiguous / not-found). * fix(mcp): gate explain no-taint-layer note on taintModelVersion (#2083 review) An M1/M2-era --pdg index has meta.pdg defined (BasicBlock/REACHING_DEF recorded) but no taintModelVersion and zero TAINTED rows. The probe keyed on generic meta.pdg presence, so explain returned the generic empty note instead of the actionable 'no taint layer — run analyze' hint. Gate on meta.pdg?.taintModelVersion (the field M3 stamps) so an M2-era index gets the layer hint; a taint-stamped index with no findings still gets the generic note. * fix(taint): sequence-expression value flows only the final operand (#2083 review) A comma expression in value position (exec((log(x), 'safe'))) default- descended, fanning every operand's occurrences into the enclosing sink argument — over-tainting exec's arg 0 with x. Add an explicit walkValue case that records earlier operands' uses with occurrence fan-out suppressed (new FactAccumulator.suppressOccurrences) and routes only the last operand through the value path. Sites-layer only; defs/uses/mayDefs byte-identical (cfg + reaching-defs snapshots unchanged). * perf(taint): FIFO head-cursor worklist + dedup before chainHops (#2083 review) Replace queue.shift() (O(N) dequeue) with a strict-FIFO head cursor plus order-preserving prefix reclamation; FIFO is load-bearing because chainHops reads the live taints map whose parent/source/viaCall are rewritten order-sensitively on monotone shrink, so hop determinism is dequeue-order contingent. Extract findingKey() and dedup-check before chainHops in the justify branch — already-recorded identities discard their hop chain (first write wins), so the ancestry walk was pure waste. The else kill branch is untouched. Findings + hops byte-identical (snapshot unchanged). * perf(taint): O(1) member-read dedup via composite-key set (#2083 review) addMemberRead rescanned the whole per-statement sites array per call to dedup by (object, property, parent) — O(n^2) on member-read-dense statements. Track a composite-key Set alongside sites for O(1) dedup. (The require-literal join is already O(sites) with a no-op body on non-require sites, so no early-exit is needed there.) Behavior identical: harvest + model-match + taint snapshots unchanged. * refactor(taint): drop test-only export; source taint caps via emit.ts (#2083 review) Remove the sanitizerNeutralizes export (its only consumers were two test assertions — inlined to entry.neutralizes membership). Re-export the DEFAULT_PDG_MAX_TAINT_* caps from emit.ts and point run.ts at emit.ts, so the pipeline's taint dependency surface is the single orchestration module rather than reaching into propagate.ts. * test(taint): extract the shared TS CFG/taint test harness (#2083 review) The parse/collectFunctions/cfgOf/cfgsOf/importsFor harness was copied byte-for-byte across four suites (harvest, model-match, propagate, taint-emit). Promote it to test/helpers/ts-cfg-harness.ts and import it. site-safety/reaching-defs carry a structurally different inlined builder and are left as-is. Pure extraction, no assertion changes. * test(mcp): harden explain limit-rejection battery (#2083 review) Add NaN, Infinity, -Infinity, and a numeric string to the out-of-bounds limit cases — a regression fence over the interpolated LIMIT, confirming the Number.isInteger guard rejects every non-integer/non-finite/string input before it reaches the query. |

feat(mcp): paginate list_repos to avoid client token truncation (#2119) (#2120)
* feat(mcp): paginate list_repos to avoid client token truncation (#2119) list_repos returned every indexed repository in one unpaginated array, which large/LLM MCP clients truncate by token limit — so agents with hundreds of indexed repos could not enumerate them all (the data transmits fully; the consuming client drops it). Add bounded limit/offset pagination to the list_repos tool: - result changes from a bare array to { repositories, pagination: { total, limit, offset, returned, hasMore, nextOffset } }; default page 50, max 200 (shared constants) - reject malformed limit/offset; clamp limit above the max - deterministic order (lower-cased name, then path) over one registry snapshot per call, so paging never skips or duplicates an entry - covers both stdio and remote /api/mcp (shared createMCPServer/callTool) The internal listRepos() method (5 callers), GET /api/repos, and the `gitnexus list` CLI are unchanged. The array->object tool-result shape is a deliberate contract change, documented in CHANGELOG. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(mcp): reject list_repos limit above the max instead of clamping (#2119) parseListReposPagination silently clamped limit>max to the maximum while throwing on every other out-of-bounds value (limit<1, offset<0, non-integer, NaN). A client that advanced offset by its requested limit (rather than pagination.nextOffset) then silently skipped repositories and saw hasMore:false — defeating the "never skips" guarantee. Reject an over-max limit too, so validation is symmetric and a caller never gets a smaller page than it asked for without a clear error. Updates the schema/description, the helper + ListReposPagination JSDoc, the guide note, and the two clamp tests. Resolves the cross-engine-corroborated P2 (Codex + adversarial lane) and the maintainability lane's clamp-vs-throw inconsistency from the PR #2120 review. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(mcp): name the list_repos return type and mark the parser @internal Extract the inline listRepos() element shape into an exported RepoListing interface and use it for both listRepos() and listReposPage().repositories, replacing the opaque Awaited<ReturnType<LocalBackend['listRepos']>> expression the maintainability review flagged. Tag parseListReposPagination @internal (it is exported only for unit testing). Pure type/JSDoc change; no behavior. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(eval-server): type formatListReposResult to the paginated shape Narrow formatListReposResult's parameter from `any` to { repositories: RepoListing[]; pagination?: ListReposPagination } and drop the dead bare-array branch — after #2119 callTool('list_repos') always returns the paginated object, so the Array.isArray shim was unreachable. Add a list_repos continuation hint to the eval-server's getNextStepHint (parity with the MCP server), and cover the previously-untested non-empty + hasMore:false formatter branch. Migrates the two bare-array formatter tests to the object shape. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(mcp): harden list_repos pagination coverage - Exercise the #2054 sibling-clone guarantee through the real callTool tool path (in the #2054 describe, which has temp-dir cleanup), proving siblings and remoteUrl survive listReposPage's sort+slice — not only listRepos(). - Assert total + limit on the middle-page test (a total miscalculation at a non-zero offset would otherwise slip past it). - Cover the benign boundaries: negative-zero offset (accepted as page 0) and a MAX_SAFE_INTEGER offset (empty page). - Replace the integration test's '\n\n---' split with a string-aware brace scan, so a repo path containing braces can never truncate the JSON parse. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(skills): sync the list_repos pagination example to the guide mirrors The .claude and gitnexus-claude-plugin guide mirrors only carried the one-line table note; add the full "Paginating list_repos" section (shape + multi-page traversal example + notes) so all three guide copies are byte-consistent with the canonical gitnexus/skills/gitnexus-guide.md. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * chore: drop list_repos CHANGELOG entries from this PR Restore gitnexus/CHANGELOG.md to match main so this PR contributes no changelog change; the changelog is curated separately from feature PRs.

feat(mcp): add tool safety annotations (#1127)
* feat(mcp): add tool safety annotations * test(mcp): address PR #1127 review follow-ups - Replace private `_requestHandlers` SDK access in server.test.ts with `Client` + `InMemoryTransport.createLinkedPair()` for the tools/list annotation propagation test. The new path uses supported public APIs and surfaces SDK changes loudly instead of silently degrading. - Extract `OPEN_WORLD_READ_ONLY_TOOLS` set in tools.test.ts so future read-only open-world tools can be added without rewriting the invariant; preserves the current "only `query` is open-world" guard. - Add inline rationale on `group_sync` annotations explaining the conservative `idempotentHint: false` (writes contracts.json on every call even when output is deterministic). No runtime behavior change. Annotations themselves and tools/list shape are unchanged. --------- Co-authored-by: Gergo Magyar <gergomagyar@icloud.com> |

feat(group): add sync pipeline, CLI, MCP tools, and monorepo fixture
Wire extractors into the sync pipeline with service boundary detection. GroupService provides high-level API for all group operations. - Sync pipeline: orchestrates extraction (HTTP, gRPC, topics) with service boundary assignment and exact matching - GroupService: groupList, groupSync, groupContracts, groupQuery, groupStatus (groupImpact deferred to cross-repo follow-up PR) - CLI: group create/add/remove/list/sync/contracts/query/status - MCP tools: group_list, group_sync, group_contracts, group_query, group_status - Monorepo fixture: 3 services (auth/orders/gateway) connected via gRPC + Kafka + HTTP — all intra-repo cross-links discovered - Documentation: CLI commands and MCP tools added to both READMEs Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> |

* 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. |
