+Goal:
+Complete the Context System + Evaluation phase with an end-to-end smoke test, implementation report, durable baseline audit, and cleanup ledger updates.
+
+Scope:
+- Add a deterministic smoke test that exercises AgentKit `build_context` composition with Coding Agent KB retrieval, test-failure evidence, and memory reference context.
+- Produce the final context-system implementation report.
+- Audit ADR-0034 acceptance criteria against executable tests.
+- Update the G12-G24 ledger with landed PR status and G24 verification evidence.
+
+Out of scope:
+- New retrieval algorithms, ranking changes, or production integrations.
+- AgentKit runtime, `ContextBuilder`, or directive schema changes.
+- External LLM calls, external judges, production credentials, or remote vector stores.
+
+Context:
+- ADR:
+  - `docs/adr/0034-context-system-boundaries-and-evidence.md`

+Loop policy:
+- Engineer adds the final smoke test first.
+- Engineer updates report/ledger only after smoke coverage is executable.
+- Reviewer reports only P1/P2 issues.
+- Engineer fixes accepted P1/P2 findings and reruns target tests.
+
+Stop conditions:
+- Stop if end-to-end smoke requires changing AgentKit runtime composition.
+- Stop if verification requires external services or credentials.
+- Stop if the final audit finds an unmet ADR-0034 acceptance criterion without an executable test.
+- Stop after two failed fix iterations for the same failure.

+# Context System + Evaluation Implementation Report
+
+Date: 2026-05-19
+Scope: G12-G24
+
+## Summary
+
+The Context System + Evaluation phase is implemented in Coding Agent without moving repository, failure, memory, or evaluation semantics into AgentKit Core. AgentKit still composes plugin-supplied context through the existing `build_context` hook; Coding Agent owns retrieval, context packs, evidence policy, observability counters, and deterministic evaluation fixtures.
+
+Memory grounding now follows the ADR authority boundary: evidence-backed memories render as reference context and unevidenced legacy memories are omitted from default grounding. Repo chunks and test failures render through the same context-pack model as memory references.
+

+
+## Durable Baseline
+
+The G24 smoke test proves the integrated path that matters for runtime safety: `Pipeline._stage_build_context` gathers Coding Agent KB and memory plugin context through HookRuntime, composes it through AgentKit `ContextBuilder`, and produces LLM-visible reference grounding without a pipeline rewrite.
+
+The durable baseline remains local and deterministic:
+
+- Fake embedders and local fixtures are used for retrieval and evaluation.
+- No external LLM, external judge, production credentials, or remote vector store is required.
+- Observability tests assert metadata-only retrieval attributes and avoid raw prompt/content/result text in span attributes.
+- JSONL tape and memory compatibility are covered by evaluation adapter tests and memory persistence tests.
+- AgentKit `build_context` and runtime-stage span tests remain the guardrail for generic runtime behavior.
+
+## Residual Risks
+
+- Retrieval quality is deterministic and fixture-proven, not production-tuned. Richer ranking/query shaping remains future work.
+- Memory evidence inference is conservative and mostly file-tag based. Session, tape-entry, command, and failure evidence fields are supported, but richer capture policy can be expanded later.
+- Unevidenced legacy memories remain persisted and loadable, but are intentionally hidden from default grounding.
+- Evaluation fixtures cover representative local cases; broader benchmark coverage can be added without changing the AgentKit boundary.
