 | CTX-08 Distributed similarity-search | Implemented | Python planner resolves `query_id` once, creates deterministic shard plans, worker adapter emits exact partial top-k CSVs/metrics, and reducer matches the local reference. |
 | CTX-09 Reducer and final-result API | Implemented | Atomic `reducing` claim, deterministic coordinator-side top-k reducer, sanitized reducer failure, final artifact persistence, `result_uri`, and final CSV download. |
 | CTX-10 Distributed similarity-graph | Not started | Local reference exists; the SDK-built local graph workload already enforces the pair-coverage invariant. |
-| CTX-11 Dashboard/operator view | Implemented | Protected live control room: recent-run/worker overview, real pipeline-stage visualization, shard attempts and safe failures, validated similarity-search upload, coordinator artifacts, final-result download, bounded polling, and a Workload library page rendering the embedded catalog from `scimesh workload export` (`/ui/workloads`, regenerated via `make workloads-export`). |
+| CTX-11 Dashboard/operator view | Implemented | Protected live control room: MkDocs documentation served at `/ui/docs/` (SCIMESH_DOCS_DIR; the demo mounts `site/` automatically), recent-run/worker overview, real pipeline-stage visualization, shard attempts and safe failures, validated similarity-search upload, coordinator artifacts, final-result download, bounded polling, a Workload library page rendering the embedded catalog from `scimesh workload export` (`/ui/workloads`, regenerated via `make workloads-export`). |
 | CTX-12 Reliability, security, CI | In progress | Unit, race, PostgreSQL integration, and smoke checks exist; CI hardening remains. |
 | CTX-15 User Service and access control | Implemented | User/owner scoping, verified contributors, worker keys, self-service enrollment, and quorum-backed untrusted workers are merged; local Go/Python and Docker/PostgreSQL checks passed. |
+| MkDocs documentation site | Implemented | A standalone documentation site (`mkdocs/`, `docs_dir: mkdocs`) covering the complete Workload SDK: guides (overview, authoring workloads, CLI, worker integration), the full auto-generated API reference for all 15 `scimesh.sdk` modules (mkdocstrings), and the writing rules (`mkdocs/approach.md`). Built with `make docs`, served inside the UI at `/ui/docs/`; the project's internal `docs/` directory is not part of the site. |
 | CTX-16 Workload SDK foundation | Implemented | `scimesh.sdk` provides strict immutable manifests/plans/artifacts, digest/trust-pinned tasks, typed DAGs, compatibility negotiation, verifier primitives with owner/binding-safe quorum inputs, resource eligibility/local allocation, measured package discovery, a trusted local core-batch conformance harness, and strict package discovery. Enforcing coordinator/Worker profiles remain fail-closed. |
 | SDK roadmap step 3: `descriptor-batch` | Implemented | The first SDK-built reference workload (`scimesh/workloads/descriptors/`): pinned 81-name RDKit 2D descriptor set, canonical one-row-per-input CSV, deterministic row-bounded shards, shard-index concatenation with one header, byte-identical local/distributed output, and a two-worker `untrusted_quorum` verifier test. |
 | SDK-built `similarity-search` and `similarity-graph` | Implemented | Both workloads are SDK-built packages (`scimesh/workloads/search/`, `scimesh/workloads/graph/`) built on the `MapReduceWorkload` authoring scaffold (`scimesh/sdk/batch.py`); they reuse the local scientific cores and are byte-identical to the single-process references (search; graph for both threshold directions and any block size). The graph reducer enforces the CTX-10 pair-coverage invariant. `scimesh/workloads/library.py` composes the built-in registry/runtime. |
