glenn schrooyenandClaude Opus 5.5 06aa09e28c SAFETY-73 review: a refusal needs 22 s of evidence, and the cut-out warning is for giving only
infra-pin / fresh (pull_request) Successful in 1s
Details
checks / unit (pull_request) Successful in 10m11s
Details 
- REFUSED_SPAN_S: the 12 cycles of evidence must also span (SETTLE_CYCLES-1) *
  LOOP_TICK_S = 22 s. At a 1 s meter, lagged healthy readings refused both
  units 10-16 times an hour after load steps (site held 0 W). 2 s and slower
  ticks are unchanged.
- REFUSES_ABOVE_CUT_OUT only for a refusal to give power: a full battery that
  stops taking charge is always above its cut-out level.
- test_delivery: its wedged fixture (0.2 s cycles) no longer reaches a refusal;
  the release/1.0 checks are restored and a span check added.
- test_refusal_units: lagged-reading and full-battery plants, two new checks,
  U14/U15 in the mutation table. Stale "> 500 W" wording fixed. DOCS/DECISIONS.

SAFETY-52's hold applied per unit at N>1 (owner, 2026-09-27, option R).
A unit that gives < 100 W for 12 cycles in one direction while asked
> 200 W, or trips its stale-reading gate on a ~0 W reading, gets a
P_SAFETY `refused` unit limit closing that direction, so the allocator
hands its share to the others within their own limits. Probe: a +-200 W
pin every 15 min, one unit at a time, only while the site asks 200 W that
way. All units refusing: the site law holds 0 W. Exits reseed the site
target from the wire. INFO plus one WARNING (REFUSES_ABOVE_CUT_OUT) above
the configured cut-out; SAFETY-42/43 no longer report a refusing unit.
N=1 unchanged.

test_refusal_units.py: cases a/b/c on flat and jitter registers against
the old behaviour, probes, recovery, exits; mutations U1-U13 all red.
TEST-19 no-fault campaign: 0 engagements in 5280 runs.
