From 86c7abdb7f4a217a35fde892689edec799f855ac Mon Sep 17 00:00:00 2001 From: kjgbot Date: Sun, 30 Aug 2026 15:57:45 +0200 Subject: [PATCH] drive: WP-2). Gate 1 is GREEN. The kernel tests pass (19+19+1+1+26+5 = 71 passed). Work produced by cloud run 1e641fc6-9f4d-449d-b5e4-2fbdc2e0581a in a workflow sandbox and delivered from this host, because a sandbox has no remote and no GitHub token.

The worker side of the protocol is simply unimplemented, and that is what blocks gate 2 ("a workload RUNS as a relayflow" — today a run can only be shown CREATED) and gate 3 ("every claim/lease/retry served by the kernel"). ## Files in scope -- `sdk/src/work-package-validator.ts` — new file, the validator function -- `sdk/src/index.ts` — export the validator -- `sdk/tests/work-package-validator.test.ts` — new file, comprehensive tests -- `sdk/src/failure-kinds.ts` — add typed refusal reasons if needed +- `sdk/src/worker.ts` — the new worker implementation +- `sdk/src/index.ts` — export the worker +- `sdk/tests/live-kernel.test.ts` OR a new test file — end-to-end test of a real flow with an agent step against live `relayflowd`, with this worker attached ## Definition of done -ALL of the following must hold: +All of the following MUST hold: -1. **The validator exists in sdk/src, exported from sdk/src/index.ts** +1. **The worker in sdk/src, exported from sdk/src/index.ts** + - attach for `agent` steps with the pins it holds + - on `step.dispatch`, run the step's declared `cli` as a subprocess + - report the result back through the existing protocol (`step.complete`, and the failure path when the CLI exits nonzero) + - nothing speculative: no retries of its own, no scheduling, no LLM calls.
