mcp/bench/tools/post.py

"""post.py ITEMS CASES [--go [--publish]]: the kai_* tool reads as research-API records, `POST /v1/research/{benchmarks,runs,artifacts}`.

ITEMS holds the per-item results a read wrote (`injection.{dev,test}.jsonl`, `command.hermes.jsonl`,
`select.{t1dev,hand}.jsonl`, `triage.ci60.jsonl`), each row the answer of every arm: `measured` (this repo's
handler at COMMIT) and `ae4d07b` (the handler it replaced). CASES holds the cases those rows were read on.
Every measure is computed here from the items, so a number shown anywhere traces to a stored row. One
`Benchmark` a tool (`mcp.injection`, `mcp.command`, `mcp.select`, `mcp.triage`), one `Run` an arm and split,
and the items and the cases as artifacts. Without --go it prints the records and sends nothing. The server
stores every write private; --publish then grants each run and artifact public (`POST /v1/research/grants`),
which is what hanzo.ai/benchmarks reads. Records are filed under the token's project (`default`). Token:
HANZO_API_KEY, else `hanzo auth token`. COMMIT: the measured handlers' commit (env, default HEAD).
