repin + fix #305 + fix #40 - #316
Conversation
…indow at all v83's guard required hasSleepWindow, which was the exact counterexample #305 named — a re-stage whose RR/HR substrate aged out can come back NO_SLEEP_DETECTED (no window at all), not just a truncated one, and that's just as much a regression against an existing real result. drop the hasSleepWindow requirement; the caller's existingHadNight check is still what protects an honest no-sleep day. kAlgoVersion 84 -> 85.
…=0 guess analytics finally exposes NapWindow.startsAtRecordEdge, propagated through the whole napChainGapSec chain, not just the first bout. the old nap.startSec == 0 proxy only ever caught that first bout — a fragment chained onto it by a brief midnight arousal had startSec > 0 and slipped through uncounted, double-crediting the same nap's minutes to both days. test it directly instead. added a regression test for the chained-fragment case. kAlgoVersion 85 -> 86.
Reviewer's GuideThis release-preparation PR repins protocol and analytics, bumps the persisted algorithm version through 86, broadens night-result regression protection to cover no-window restages, and fixes midnight nap double attribution by using analytics-provided edge provenance for chained fragments.

📝 WalkthroughWalkthroughThe change pins updated protocol and analytics revisions, raises the algorithm version to 86, broadens night-substrate regression detection, and uses ChangesAlgorithm updates
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The restaging change is intended to preserve historical night results, but the current implementation can mistake daytime heart-rate data for a valid night result and overwrite existing RMSSD and readiness values with nulls. This creates a high-impact data-correctness risk, so the PR should not merge until the check uses a nocturnal-only signal.

Hey - I've reviewed your changes and they look great!
Sourcery assessment
Needs a human reviewer. The updated derivation and analytics logic changes persisted values such as heart-rate ceilings, irregular-rhythm screens, and nap minutes, and the repinned libraries also alter the code producing them. If those changes are wrong, versioned records may retain incorrect derived results after a revert, but the affected values are bounded and can be regenerated or repaired.

Do not use fallback rhr as proof that night substrate is present.
A no-window re-stage can still produce scalars.rhr from daytime HR. In that case, sleepSub.isEmpty is true, but nightScalarsNull is false because it checks scMap['rhr']. The guard then writes null rmssd and readiness over the existing historical values.
Use a nocturnal-only indicator for both the fresh-result and existing-result checks. For example, inspect rhr_nocturnal or the persisted sleep window instead of the fallback rhr. This also prevents an honest no-sleep result from being classified as a historical night.
