 | Digest (thirteen-field base, sixteen-field refusal) | b7cc37e7, sha256 bc28331abf21f4d5 | 12:14:39 to 12:16:18 | PASS: thirteen fields a89be8a7 on both binaries, peers as the gate wants them; sixteen fields db9a85f9, refused, no peer; the live file's own digest eada4bda unmoved |
 | Kept-datadir start (the fleet, p12-vast's copy of pool-1's 0.3.17 datadir) | b7cc37e7 | 12:17:12 and 12:18:53 | PASS: the first start reads the v1 row through the mirror and rewrites it ("1 mergeset rewards"), the finality blob converts (1,747 locks), the node up on its ports, no panic; the second start reads first-try, no rewrite line; 6a3432a3 died on the same copy (the known-failed shape) |
 | Mixed-version, ten minutes beside the 5899f603 pair | b7cc37e7 | 12:16:39 to 12:27:21 | FAIL, the binary: clean to the restart step (one digest b0afb2ee on all five, 268 new and 392 old accepted, 0 rejected, counts equal at 324 and 502 through both joins), then the restarted new node died on its own datadir, "While lock file .../meta/LOCK: Resource temporarily unavailable" (conn_builder.rs:167): the listener watchdog from 6a3432a3 slept its whole 10 s poll before checking shutdown, so every node on the line since took up to 10 s longer to stop and the restart met the lock; three more failed checks follow from that one death. Fixed in c4459193 (the poll in 250 ms steps returning on shutdown; `a_shutdown_returns_within_a_second_whatever_the_poll`) |

+| Digest | c4459193 (the candidate pin), sha256 45be9b02d1b002f5, the string read back | 12:33:27 to 12:35:05 | PASS: thirteen fields a89be8a7 on both binaries with the peers as the gate wants them; sixteen fields db9a85f9 refused, no peer; the live file's digest eada4bda unmoved |
+| Mixed-version, ten minutes beside the 5899f603 pair | c4459193 | 12:35:26 to 12:45:39 | PASS: one digest b0afb2ee on all five, 215 new and 314 old blocks accepted, 0 rejected, plain header version 2, counts equal at 312, 441 and 529 through both clean joins and the restart step (the new node restarted on its own datadir and resynced), no panic in any log, every check green |
+| Kept-datadir start | c4459193 (carried from b7cc37e7: the store code is identical; the fleet's canary re-reads it on this binary) | | the b7cc37e7 lines above |
+| Shutdown within a second | c4459193 | 12:29 (build-2) | `a_shutdown_returns_within_a_second_whatever_the_poll` green in the exec suite's 31, beside the two other watchdog tests |
 | Digest | 6b94c823 (the fallback, sha256 b1b7d47b) | 11:56:45 to 11:57:52 | compat and refusal digests right; the one failed check read n3's peers at 1 with its refusal line present (the refused connection's reconnect in flight; the read is now the minimum of five, 36d3efdc) |
 | Mixed-version | 6b94c823 | 11:57:53 to 12:08:05 | one digest b0afb2ee on all five, 146 new and 246 old blocks accepted, 0 rejected, counts equal through both joins and the restart; the one failed check: six "Address already in use" panics in the two OLD nodes' server threads, the gate started the second the digest gate's nodes got SIGTERM on the same ports (a 20 s gap now) |
 | Mixed-version on the live sixteen-field file (void: the binary at the path was replaced mid-run) | 8097d600 | 11:42:55 to 11:53:07 | the interop fact: one digest on all five, the 5899f603 hub accepted 235 byte-5 blocks from the new node with 0 rejected, old headers 1026 (byte 4), new 1282 (byte 5), counts equal on all five at 472 before the restart step |
