| 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. |
| SDK-built `molwt-filter` | Implemented | The minimal authoring example (`scimesh/workloads/molwt_filter/`): filters molecules by exact RDKit molecular weight with only one scientific hook, using the scaffold's new default sharding and concatenation hooks. Registered in the built-in library and as a `scimesh.workloads` entry point. |
| SDK authoring scaffold | Implemented | `MapReduceWorkload` (exported from `scimesh.sdk`) assembles manifest, map/reduce stages, workflow, and digest-pinned handlers from three scientific hooks (partition/compute/merge), with overridable hooks for domain validation, plan-time resolution, custom task planning, and partial-key policy. The generic `scimesh workload list|run` CLI and the worker's allowlist-driven loading (`SCIMESH_WORKLOAD_ALLOWLIST`, `SCIMESH_CAPABILITIES`) let new workloads run without touching other code. |
