| 1.1c | PolicyEngine package | ✅ | `build/phase-1/step-1.1c-policy-engine-package` | [#46](https://github.com/officialCodeWork/AgentContextOS/pull/46) | New `packages/policy/` (`rag-policy` v0.1.0): `PolicyEngine` SPI + `NoopPolicyEngine` (always-ALLOW with tenant-scoped `filter_pushdown`); `PolicyDecision` enum (read_chunk / ingest_doc / egress_text / quota_check / rate_limit / execute_plan); `PolicyResult` (allow/deny/transform) with predicate helpers; `QuotaSubject` / `RateLimitSubject`; `FilterExpr` mini-language (Eq / AnyIn / And / Or / Not / TrueExpr) returned by `filter_pushdown`; `PolicyWriter` facade mirroring `AuditWriter` and emitting `policy.decision` structured logs via `rag-observability`. Coverage linter `tests/policy/coverage.py` greps for governance-relevant SPI calls without adjacent `PolicyEngine`/`PolicyWriter` consultation, with file allowlist that consumers shrink as they wire the PDP in. Workspace + pytest pythonpath updated. 20 conformance tests added. ADR-0005 finalized. |
| 1.1d | Pipeline + Batcher primitives | ✅ | `build/phase-1/step-1.1d-pipeline-batcher-primitives` | [#50](https://github.com/officialCodeWork/AgentContextOS/pull/50) | `Pipeline` primitive in `rag-core` (`rag_core.pipeline`): async DAG with bounded queues, per-stage worker counts, backpressure, joiner-based shutdown handling per-stage worker-count differences, `on_error="fail"`/`"skip"` policies, optional `error_handler`. `Batcher[Req, Resp]` middleware (`rag_core.batcher`, DataLoader pattern) coalescing concurrent `load(req)` calls into batched `batch_fn(reqs)` invocations; size + time triggers (`max_batch_size`, `max_wait_ms`); per-request `asyncio.Future` for isolated error propagation; `flush()` for deterministic shutdown. PEP-695-typed generics. 22 unit tests (8 Batcher + 14 Pipeline). `docs/architecture/pipeline-batcher.md` + `rag-core` reference + `performance.md` backlinks. `rag-core` 0.5.0 → 0.6.0. |
| 1.1e | Cache SPI split + perf discipline + async telemetry | ✅ | `build/phase-1/step-1.1e-cache-split-perf-telemetry` | [#51](https://github.com/officialCodeWork/AgentContextOS/pull/51) | `EmbeddingCache` (`rag_core.spi.embedding_cache`, key tenant+model_id+model_version+text_hash, `invalidate_model`), `RetrievalCache` (`rag_core.spi.retrieval_cache`, key tenant+plan_hash+corpus_version, `invalidate_corpus`), `AnswerCache` (`rag_core.spi.answer_cache`, key tenant+plan_hash+corpus_version+policy_version, `invalidate_policy`). All ctx-first; signature linter extended. Noop in-memory impls + 18 conformance tests covering hit/miss/version-partition/invalidate/tenant-isolation. `AsyncTelemetrySink` in `rag-observability` — bounded buffer (default 10_000), non-blocking `submit()`, per-kind drop + exporter-error counters, idempotent start/stop, drain-timeout-cancel; 9 unit tests. Hot-path discipline doc in `performance.md` expanded with concrete hot/cold call-site table. New `docs/reference/rag-observability.md`. `caching.md` SPI shapes updated with ctx-first signatures. `rag-core` 0.6.0 → 0.7.0. |
| 1.1f | ADRs 0005–0009 + reviewer checklist | 🚧 | `build/phase-1/step-1.1f-adrs-reviewer-checklist` | — | ADR-0005 (PolicyEngine PDP), ADR-0006 (two-stage reranker default), ADR-0007 (tiered storage with BlobRef), ADR-0008 (cost-aware planner replacing reactive fallback), ADR-0009 (vector index strategy + quantization) all promoted to Accepted with implementation-path backlinks. Reviewer checklist in `docs/architecture/performance.md` extended with explicit items for plan/budget awareness, IndexHint+dtype handling, two-stage rerank shape, and BlobRef-safe consumers. ADR backlinks added to `rag_core.spi.reranker` and `rag_core.spi.storage` (the two missing module-level pointers). |
