glenn schrooyenandClaude 09e1fbb898 SAFETY-128: control does not act on late Home Assistant readings
checks / unit (pull_request) Successful in 19m36s
infra-pin / fresh (pull_request) Successful in 1s
Readings that Home Assistant delivers late but still changing passed
every staleness gate, so the loop corrected again each cycle an error
its last command had already fixed (10 s late: the give run swung and
exported to -1.9 kW), and the peak guard pushed to the inverter limit
on the same late figures (OPT-34 F-2).

app/lateness.py fits how long after a power request the meter shows
it. Over 8 s the readings are late: a request the battery reading has
not answered holds the loop (it may not lead the reading by more than
100 W) and caps the peak guard at what stands; unanswered for 23 s it
holds, then 0 W after stale_input_s. An amber row and one log line per
episode say so. With readings on time nothing changes (digests equal).

adminandClaude Opus 5.5 6918e154c8 SAFETY-97: "gives nothing" is graded against each battery's idle reading
checks / unit (pull_request) Failing after 29m7s
infra-pin / fresh (pull_request) Failing after 2s
B's power reading shows -95 to -118 W at idle (standby draw), so the
|reading| < 100 W refusal band never held a refusing B: never at N=2,
and since SAFETY-94's shared rule not at N=1 either (review F1).

Each unit now learns its idle reading (app/idle.py): only while control
runs, the unit is not refused/stale/tripped and its command has stayed
within 50 W for 120 s; first value a 120 s mean, then a 30 min follow;
samples beyond 250 W dropped, value clamped to 250 W; saved per unit and
restored. The shared refusal evidence, compute()'s N=1 engage and end,
the unit refusal ends, the stale-path refusal and SAFETY-42's "parked"
test are centred on it. Until learned it is 0 W, the rule as it was.

Refusing B caught at N=1 28/28/65 s and N=2 24/24/60 s (1/2/5 s
meters), before never; refusing A unchanged. Healthy B with its offset,
SAFETY-94's scenarios, 96 runs: 0 stale, 0 refused. Live replay: 0.

glenn schrooyenandClaude Opus 5.5 dd5eb6fdc8 SAFETY-94 review: tests for three surviving mutants; record two gaps
checks / unit (pull_request) Successful in 28m7s
infra-pin / fresh (pull_request) Failing after 2s
- test_safety94 part 4: time under 250 W is not counted; a command that
  swaps direction every cycle is never refusal evidence; a reading moving
  away from the ask does not restart the evidence. These kill review
  mutants R1, R3 and R6, which survived the PR's tests.
- DECISIONS: at N=1 a battery with B's standby offset no longer latches
  a refusal (SAFETY-97 now covers N=1); a part-time ask is caught after
  35/d s of wall time.

adminandClaude Opus 5.5 6759d21ea5 SAFETY-94: a healthy battery that lags or reverses is not flagged as frozen or refusing
checks / unit (pull_request) Successful in 28m10s
infra-pin / fresh (pull_request) Failing after 2s
The stale-reading gate counted its 35 s from the register's last change, so
after a rest the first read after a new command tripped it (SAFETY-58; live
2026-10-03, four trips 1 s after the command). It now counts only the time
the command asked the register to move.

At N=1 the refusal engaged after 12 frozen cycles if the reading was under
100 W at that moment, which a battery reversing through its lag passes at a
1 s meter. The refusal now needs the N>1 evidence at every roster size: under
100 W, one way, for 12 cycles spanning 22 s, restarting when the reading
moves 50 W towards the ask.
