RING2-PKG-7: no-op — emitter already shipped in base

[Copilot]

Phase 5 of RFC #909 asks for a ReferenceIndex → graph-edge emitter with confidence/evidence JSON props and an opt-in ScopeTree flush. After investigation, the entire feature is already present in this branch's base commit (PR #973) — branch HEAD has zero diff against base for the feature scope.

Verification against deliverables

• gitnexus/src/core/ingestion/emit-references.ts — iterates referenceIndex.bySourceScope, maps Reference.kind → existing RelationshipType (call→CALLS, read/write→ACCESSES with step=1|2, inherits→INHERITS, type-reference/import-use→USES), and stamps confidence + serialized evidence on each edge. Schema is preserved per the acceptance criterion.
• Optional emitScopeGraph flush (Scope nodes + CONTAINS/DEFINES/IMPORTS) gated on INGESTION_EMIT_SCOPES=1 (1|true|yes, case-insensitive); off by default.
• Unit suite at gitnexus/test/unit/scope-resolution/emit-references.test.ts — 12 tests covering kind mapping, enclosing-def resolution (function ancestor / class fallback / no-caller skip), missing-target skip, scope-graph on/off, env-flag parsing, empty-input no-op. Passes locally; tsc --noEmit clean.

Honest gap

The "full pipeline Python file → graph edges" integration test deliverable is not implementable yet: the resolution phase that populates ReferenceIndex from ReferenceSite records hasn't landed (see headers in emit-references.ts and finalize-orchestrator.ts:22). A hand-built ReferenceIndex test would duplicate the existing unit coverage without exercising new wiring. This integration test belongs in the resolution-phase PR, where it can consume real Reference records.

Diff in this PR

Single incidental change: gitnexus/package-lock.json re-synced from 1.6.1 → 1.6.2 to match package.json (produced by npm install during validation). No source changes.

Recommendation

Close as superseded by #973, or repurpose to track the resolution-phase integration test once that phase lands.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• extension.ladybugdb.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/GitNexus/GitNexus/gitnexus/node_modules/.bin/vitest run test/unit/scope-resolution/emit-references.test.ts yp lines; -I k/GitNexus/node_modules/.bin/node-gyp -I /home/REDACTED/.ca-c -I src/parser.o.d /hom�� e --64 es/.bin/sh (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
