 - 2026-08-13T01:31:53+00:00: structured pre-dispatch manifest created.
 - 2026-08-13T01:36:00+00:00: attempt-1 stopped before implementation because the worker branch predated its queue Goal; zero writes. PMO authorized only a fast-forward to the current dispatch closure and a fresh identity ACK.
+- 2026-08-13T02:04:00+00:00: product attempt remained zero-write and correctly terminaled on a PMO contract error. R10 retained authority proves exactly 22 scripts (summary SHA-256 `3de791bb...`); old `game.run` tests and non-authoritative R3 dynamic were removed from the foundation gate without editing them.
