Changelog

[0.1.0] - unreleased

Initial scaffold of codex-ulw-loop plugin.
Per-Criterion Cycle: EXECUTE is now EXECUTE-AS-SCENARIO — the agent must run the Manual-QA channel scenario the criterion named (HTTP call / tmux / browser use / computer use; see new ## Manual-QA channels section). Inserted a new CLEAN (PAIRED, NEVER SKIP) step that tears down every QA-spawned process / tmux session / browser context / container / port / temp dir before recording evidence; the cleanup receipt is embedded in the --evidence string. Missing receipt → record BLOCKED, not PASS. Added Constraint #13 and a Stop Rule for leftover state.
New top-level ## Manual-QA channels section explicitly enumerates the four channels (HTTP call, tmux, Browser use, Computer use) with concrete commands and required artifacts. Goal section now declares TESTS ALONE NEVER PROVE DONE: a green test suite is supporting evidence, never completion proof. Criterion-refinement step 2 requires each criterion to name its channel up front.
