the trailing edge defers a bout it can't see the end of. the leading edge just emitted one as if it started at index 0, so edge has to guess the boundary from a timestamp tolerance — and when the band only starts recording at midnight, both days drop the nap. new NapWindow.startsAtRecordEdge, propagated forward through napChainGapSec the same way unfinished propagates backward. still emitted: this end has a knowable END, only the onset is unknown. no nap appears or disappears and no duration moves, so nothing shipped changes value.
the day gated at 0.65*HRmax, the bout at rest + 0.30*HRR, so the same minute of the same stream was billed active by one and resting by the other — 8 to 35 bpm apart depending on the profile, and the sign flipped between them. both now call activeGateHr(hrmax, restingHr) = rest + 0.40*HRR. 0.40 is the same boundary the 0.65 choice was after: ACSM moderate is 40-59% HRR = 64-76% HRmax, so it keeps MOT-02's rigour while scaling with the individual's own rest instead of drifting toward it with age. profile old day old bout now 70y RHR 68 103.4 95.3 104.4 34y RHR 55 119.7 93.8 106.7 25y RHR 45 123.8 88.7 103.2 CHANGES SHIPPED NUMBERS, both paths. day active energy rises for anyone whose rest sits well under 0.65*HRmax (the young and fit, up to 20 bpm of extra billed minutes) and is flat for the older profile. bout kcal falls a little for easy sessions — the gate went up 9-15 bpm — and barely moves for real ones, where nearly every sample clears both. dailyEnergy now requires restingHr, no fallback, same argument as hrmax: an unknown rest is an unknown gate, so the caller abstains rather than bill a day against somebody else's rest. edge has to pass it.
quietWakingHrr = 0.20 HRR was a population figure standing in for a personal one, and it sits below where this user's waking minutes actually are (p50 0.274, whoop-4.db). the baseline then under-charges the cost of being awake and the leftover reads as training load — a day with nothing in it lands mid-scale. RHR 55 / HRmax 187 / 960 wake minutes, scored against their own 0.274: day before after nothing at all 11.93 0.00 + 60 min walk @105 12.61 2.78 + 45 min run @145 14.79 8.72 + 90 min hard @165 19.30 16.49 the nothing-day goes to zero and the light day does NOT come down with it: doing nothing and walking an hour were 0.7 points apart on a 0-21 dial, now 2.8, and the rest of the scale stays graded. a user whose quiet really is 0.20 barely moves (anchor profile, inactive: 0.00 before and after) — the level is measured now rather than assumed, so it only bites where the constant was wrong for the person. quietHrr is a required argument on strainScore/baselineTrimp and a required nullable on strainScoreMetric, which abstains with a reason rather than fall back to a constant. dailyQuietWakingHrr measures it — median waking HRR, percentile of self — and returns null for a day whose median clears 0.40 HRR (ACSM moderate), which is the day that would otherwise subtract its own hike away. feed a trailing value where you have one. CHANGES SHIPPED NUMBERS: every strain score for anyone whose quiet waking isn't 0.20 HRR. edge has to pass quietHrr from strain_backfill, onehz_pipeline, manual_session and derivation_engine or strain goes absent.

- Around line 129-137: Update dailyQuietWakingHrr to require finite resting/max
heart-rate anchors and exclude non-finite HR samples before calculating HRR,
without clamping invalid values into the distribution. Update strainScoreMetric
to return Metric.absent when quietHrr is non-finite or not in (0, maxQuietHrr],
preserving valid values for baselineTrimp. Add regression coverage for
non-finite anchors and samples, double.nan, and maxQuietHrr + 0.01.
In `@lib/src/onehz/workout/calories.dart`:
- Around line 155-156: Update activeGateHr to validate non-null anchors before
calculation: require finite hrmax and restingHr values with 0 < restingHr <
hrmax, and abstain using the existing documented null-anchor fallback when
validation fails. Preserve normal gate computation for valid anchors and reject
invalid non-null inputs.

activeGateHr returns null now when the anchors can't define a gate (non-finite, or not 0 < rest < hrmax). a NaN gate isn't a loose gate: every `hr < gate` is false against NaN, so every minute of the day billed at the keytel active rate. dailyEnergy abstains on it, the bout takes the 220/60 fallback it already documents and flags it like any other missing anchor. same class in load_trimp — every range check there is false for NaN too, so NaN walked into a present strain. also refuse a quiet-waking level above the moderate floor instead of letting baselineTrimp quietly clamp it, and drop non-finite hr samples (+inf was clamping to a maximal minute).

Three findings from re-checking every issue ever filed against the shipped code.
the day and the bout disagreed about "active" (#43). Two gates, 8–35 bpm apart depending on age and rest — the older you are the closer they get, which is backwards. Both call
activeGateHrnow: rest + 0.40 × HRR. That is the HRR statement of the boundary the old constant was reaching for (ACSM moderate is 40–59% HRR ≡ 64–76% HRmax), so it keeps the rigour and scales with the individual instead of drifting toward them with age.dailyEnergyrequiresrestingHras a result. Same argument the file already makes forhrmax: an unknown rest is an unknown gate, so the caller abstains rather than billing every waking minute as active.strain scored a nothing-day at 6.9–12.1 out of 21 (edge#226).
quietWakingHrr = 0.20was a population figure standing in for a personal one. Working, RHR 55 / HRmax 187 / 960 wake minutes, against their own measured 0.274:Nothing-day to zero, and the light day is not flattened with it — 0.7 points of separation became 2.8. Someone whose quiet genuinely is 0.20 does not move, so this is not a rescale. The 0–21 map is untouched and the anchor table still reproduces exactly.
dailyQuietWakingHrrmeasures it as the median waking HRR — percentile of self — and returns null when that median clears 0.40, which is the all-day-hike case that would otherwise subtract its own training away.nap.dart's leading edge was unguarded (#40). The trailing edge already was. A nap the band only started recording at midnight was dropped by both days. The bout is still emitted, because unlike the trailing case this end has a knowable end —
startsAtRecordEdgelets the caller defer on evidence instead of a tolerance.559 tests, analyze clean. The six skips are the real-capture fixture, which is not on this machine.
Edge repins to this in OpenStrap/edge#256 and bumps kAlgoVersion to 75 — both the gate and the strain floor move shipped numbers.
