@ -463,8 +463,14 @@ inside the (2/3)^32 = 2.3e-6 estimate), per-attempt rejection 0.67 (attempt hist
68,858 / ...), mean about 2 attempts per seed; seed 331672 accepts at attempt 32. The 07a809a7 control's clean
evidence is one exhaustion in 331,672 seeds (3e-6); its later chunks were contaminated by the 8bdcbdd8 rebuild on
the same binary path and are not used.
Status: FIXED-AND-PASSED on the exhaustion half at the 10^6 end if the count stays 0; the hot-set gate on the same
commit is the open half of sub-version 2 (AP-F8-1).
Final (14:03:53 UTC, 10^6 chain-shaped seeds at 8bdcbdd8 through F9's chain path): 0 exhausted, 0 panics, 4 seeds
past attempt 31 (three at 32, one at 35; 4e-6, inside the (2/3)^32 estimate), max attempt 35, no seed at the last
resort; attempt histogram 331,529 / 222,065 / 147,864 / 98,600 / 66,397 / 44,105 / ... / 1 at 31 / 3 at 32 / 1 at 35,
a per-attempt rejection of 0.67 and a mean of 2.0 attempts per seed. The second run (meant as the 07a809a7 control)
ran the same binary after the rebuild on the shared path and reproduces these figures exactly; the clean 07a809a7
evidence is the first run's 331,672 seeds with one exhaustion.
Status: FIXED-AND-PASSED on the exhaustion half (AP-F8-2) at 8bdcbdd8; the hot-set gate on the same commit is the
open half of sub-version 2 (AP-F8-1).
Any further finding is logged here and in `docs/fud-ledger.md` with its owning lane (hash and algorithm: fixed in
`igneum-pow` behind a test and re-gated; node: the node lane, relay agent) before the row is marked FIXED-AND-PASSED.
