#96 – Stabilize in-epoch invalid SPRT on small samples
Passed
Proposal ID: 96
Type: Update Params
Submit: 2026-08-20 18:04 UTC
Voting: 2026-08-20 18:04 UTC → 2026-08-21 06:04 UTC
Expedited: Yes
In-epoch SPRT on invalid inferences is not stable on a small sample. A few invalids can trip it before the epoch has enough data. This proposal raises invalidation_h_threshold to 40 and sets bad_participant_invalidation_rate to 18e-2. At large sample sizes the threshold is about 10% invalid, so participants below that are not punished. Higher rates still trigger, 18% in about 360 samples and 12% in about 1650. Small samples cannot trigger it. At least 32 flagged invalids are required, and at 500 samples the observed rate must exceed 16%. Downtime SPRT is unused and is turned off. Epoch-end stats tests still work.
