From 9172ca883400daef26711985f855a3e4a1ffcd17 Mon Sep 17 00:00:00 2001 From: Relayflow Lead Date: Sat, 29 Aug 2026 15:09:10 -0400 Subject: [PATCH] drive: cloud run ecf55208 Work produced by cloud run ecf55208-389f-463d-826b-8c0512de1348 in a workflow sandbox and delivered from this host, because a sandbox has no remote and no GitHub token.

CODE task, SDK-side. The picker EMITS a work package (sdk/src/backlog-picker.ts + testdata/backlog-picker.flow.yaml, merged, four tested properties) and NOTHING consumes it — that is the missing half. Build the consumer: an SDK entrypoint taking an emitted package and turning it into something runnable, validating it has a title, a non-empty scope and a definition of done, and REFUSING with a typed reason when it does not, because a package that cannot be verified must not become work. NOTE: two previous attempts (ee5c9b3e, 06c0d6ab) did this correctly and their files were LOST before delivery by a platform fault — the build sandbox's .git points at a directory that does not exist, so writes cannot be captured. You are not duplicating live work. +**Pinned to gate 3** per ops/TARGET.md. ## Objective -Build the SDK entrypoint that takes an emitted work package and turns it into something runnable. The consumer must validate that the package has: -- A title (non-empty string) -- A non-empty scope -- A definition of done +The picker reads ops/BACKLOG.md and selects the first bold top-level bullet. Currently it handles well-formed entries but a malformed entry — a bold title with no body, an unterminated backtick, a bullet nested under another — can crash or produce a half-formed package. Add handling so malformed entries produce typed refusals, never crashes and never half-formed packages. -When any of these is missing or invalid, the consumer REFUSES with a typed reason.
