SciMesh Status

Updated: 2026-07-23
Branch baseline: planning at 13f9a0b

Current state

The local Python molecular workloads are implemented and tested. They provide the reference behaviour for future distributed execution:

• similarity-search: streaming ChEMBL TSV search, Morgan fingerprints, Tanimoto scoring, heap-based top-k, CSV and image output;
• similarity-graph: exact sparse graph, block-based pair comparisons, deterministic CSV output;
• Python Worker skeleton: claim, heartbeat, input checksum validation, artifact upload, completion and failure reporting.

The Go coordinator, PostgreSQL schema, coordinator artifact storage, planner, reducer, and end-to-end distributed execution are not implemented yet.

Milestone tracker

CTX	Status	Notes
CTX-00 API and error contract	Ready to implement	docs/api-contract.md created; needs owner review/freeze.
CTX-01 Go coordinator bootstrap	Not started	Depends on CTX-00.
CTX-02 PostgreSQL migrations	Not started	Depends on CTX-00 and CTX-01.
CTX-03 Transactional queue	Not started	Depends on CTX-02.
CTX-04 Worker registry and HTTP API	Not started	Depends on CTX-03.
CTX-05 Artifact storage	Not started	Depends on CTX-02 and CTX-04.
CTX-06 Python Worker live-contract alignment	Partially prepared	Worker skeleton exists; needs real Go contract tests.
CTX-07 Distributed workload protocol	Not started	Depends on artifact and Worker contracts.
CTX-08 Distributed similarity-search	Not started	Local reference exists.
CTX-09 Reducer and final-result API	Not started	Depends on CTX-07 and CTX-08.
CTX-10 Distributed similarity-graph	Not started	Local reference exists.
CTX-11 Dashboard/operator view	Not started	Deferred until API and reducer work.
CTX-12 Reliability, security, CI	Not started	Final milestone.

Next recommended assignment

Assign CTX-00 to the coordinator role in .agents/coordinator.md: review and freeze docs/api-contract.md against PLAN.md. Do not begin coordinator or Worker API implementation until the contract owner accepts it.

Known constraints

• Distributed execution is not available; use the local scimesh CLI.
• No Go module, PostgreSQL migrations, runtime configuration, or integration environment exists yet.
• Local worker unit tests do not prove interoperability with a live coordinator.

Update rule

The integration role updates this file only after collecting command output, test evidence, and accepted changes. State facts, revision hashes, blockers, and the next unblocked CTX task; do not mark work complete based on plans alone.
