fix a batch of small stuff: strain copy, flaky tests, readiness clobber, gen5 rr, health export, sleep reject - #308
Conversation
Reviewer's GuideThis grab-bag PR hardens derivation persistence against retention-edge data loss, threads packet timestamps through Gen5 RR analysis, adds reversible full-night rejection, exports workouts from all completion/import paths, fixes database-handle test leakage, and updates the strain explanation.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change adds direct Health export from several workout-completion paths and protects readiness data near the retention cutoff. Merge readiness is currently moderate because exports may continue after consent changes, race or fail without durable recovery, and some completed-session paths may still miss export; the retention-edge safeguard also needs explicit owner follow-up.

if (rr != null) {
- for (final v in rr.rrMs) {
- if (v > 0) rrMs.add(v.toDouble());
+ // A duplicate or out-of-order packet timestamp cannot prove adjacency

}
</code_context>
<issue_to_address>
**issue (bug_risk):** The new `lastPacketTs` filter discards every later RR-bearing packet whose timestamp equals the previous packet's timestamp. Because `rr.ts` is converted from an integer packet timestamp in seconds, distinct packets received within the same second are treated as duplicates and their beats never reach `correctRr`, reducing or biasing spot-check and breathing-coherence results.
**Triggers:** When the live stream contains multiple RR packets with the same one-second timestamp.
**Suggested fix:** Use a higher-resolution packet timestamp or deduplicate using a packet sequence/identity rather than rejecting equal timestamps; only discard timestamps that are strictly older when ordering is actually guaranteed.
</issue_to_address>Sourcery assessment
Needs a human reviewer. 1 finding to address first, and if the workout-export paths are wrong, they can write incorrect or duplicate health records to Apple Health or Health Connect, and reverting this change will not undo those external writes. The sleep rejection and derivation protections are otherwise bounded and reversible through re-analysis or clearing the override.

Use nocturnal RHR for the retention check.
scMap['rhr'] is not night-only. This file documents that scalars.rhr can fall back to daytime HR, while scalars.rhr_nocturnal is the sleep-gated value at Lines 3852-3857. When daytime HR survives but sleep substrate expires, the fallback makes nightScalarsNull false. The guard then writes a row with null rmssd/readiness and a daytime rhr, replacing the historical metric_series baseline.
The existingHadNight check has the same ambiguity. Use rhr_nocturnal, or an equivalent persisted night-presence marker, in both checks.
Also applies to: 3728-3731

setWorkoutWindow overwrote the row with the new start/end, then exportWorkoutId only deleted inside that new window before writing - if a retime narrowed or moved the range the old health sample never got cleaned up and sat there stale next to the new one. now deletes the old window first, before the row gets overwritten.

Description
Analytics & Derivation: Bumped
kAlgoVersionto 83. Prevented retention-edge re-derivations from overwriting valid night metrics with nulls. Added specific diagnostic notes for readiness abstentions caused by unstable baselines (changes what is displayed when data is missing).Sleep Staging: Added support for rejecting an entire detected night as "not sleep", skipping staging entirely, with UI to undo the rejection.
Health Export: Ensured workouts completed via AI coach, stale-session reconciliation, and WHOOP imports are exported to Apple Health / Health Connect.
Gen5 RR Processing: Preserved real packet gaps by passing timestamps to
correctRrin spot checks and breathing coherence.UI & Tests: Updated day strain guidance to clarify that strain can ease. Fixed test flakiness by closing database handles between suites.
