Summary

Adds code-review gold answers from explicit BCApps PR feedback.

Negative guards use exact source-file patches at immutable reviewed revisions, not invented synthetic code. Their targets are omitted from both expected and ignored comments; new negative-only entries have no expected findings.
Existing eligible gold answers are reused without changing their payloads.

Accepted findings

Rejected findings

• Rejected precision guard: Bug 649862: [Subcontracting] Restore Get Receipt Lines for subcontracting receipts BCApps#11904 (comment)

Knowledge dependency

• Related BCQuality improvement: knowledge: improve review precision from BCApps PR 11904-neg-pr11904-20261020 feedback BCQuality#243

Validation

See the gate-owned offline evaluation section below.

Generated by the BC-ALAgentsInternal self-improvement workflow.

Offline evaluation: regression

Candidate correctness failed: unexpected or missed findings remain. Existing ignored gold comments retain their neutral scoring semantics.

Preparation attempt 1: validated.

Selection: new. New: synthetic__performance-setloadfields-returned-record-param-01. Reused (complete payloads): ``.

• synthetic__performance-setloadfields-returned-record-param-01 / false_positive_guard / Bug 649862: [Subcontracting] Restore Get Receipt Lines for subcontracting receipts BCApps#11904 (comment): The flagged FindSet iterates ItemLedgerEntry, a var parameter of IsFullTrackedOutputSetSupported that the caller (CopyTrackedSubcontractingOutputToSeparateInvoice) keeps using after the call: CopyItemLedgerEntriesUpToQuantity executes TempItemLedgerEntry := ItemLedgerEntry to buffer the whole entry for later item-tracking-specification creation, so narrowing the load to the loop's own six fields (as flagged) would drop fields that buffer still needs, exactly the caller-and-helpers caveat the cited article already states. The developer's negative feedback rejects the suggestion for this reason, not because SetLoadFields is unwanted in general, so the guard is scoped to this var-parameter/round-trip-return case and does not claim SetLoadFields is never applicable to Item Ledger Entry reads elsewhere in the file.
  Coverage references and outcome shapes are validated mechanically. Semantic equivalence, severity calibration and recommendation quality are NOT proved by these checks or a matching F1.

Missing telemetry is unavailable, not zero. Evaluation-only metrics exclude candidate generation and are not the full-cycle cost.
Human review must verify source-patch fidelity, gold correctness, and target attribution. No automatic merge or branch-protection claim is made.

Subtotals are CLI/Bench-reported usage, not invoices. Missing values are not zero. Emitted-span coverage does not prove complete child/background billing; judge usage is not exported. Premium requests are not AI credits or currency.
Nested stage, agent and API durations are not added into cycle wall clock. Root queue/setup, telemetry export, artifact upload and later dashboard publication are excluded.
PR evidence is an as-of snapshot before publication completes. Final-for-orchestrator metrics are emitted to self-improvement-cycle.json in the root self-improvement-feedback artifact and its Actions summary when persistence succeeds; a running checkpoint is not final evidence.
