NOOP 10.5.0

NOOP v10.5.0

A release about seeing your training as a shape over time, getting numbers that used to need a tape
measure, and — most of all — your phone doing far less work to tell you the same things.

Training load

CTL, ATL and form (#1423, #1425). NOOP now models chronic and acute training load and the balance
between them, and draws all three on a Trends card. Fitness accumulates slowly, fatigue quickly, and the
gap between them is what tells you whether a hard block is building you up or digging a hole. Computed
on-device from the strain you already have; no new data is collected.

Sleep-versus-wake heart rate (#1424). The contrast between your sleeping and waking heart rate,
surfaced as its own signal rather than buried inside recovery.

A VO₂max you can actually get

Estimated without a waist measurement (#1391, #1406, #1393). The previous estimate needed a waist
circumference many people never enter. If NOOP knows your resting heart rate, it can now use the Uth
heart-rate-ratio method from age and sex alone, and it names which method produced the figure. An
estimate that says how it was reached is worth more than one that doesn't.

Battery

Stop re-scoring days that haven't changed (#1005, #1395, #1396, #1402). NOOP re-analysed a rolling
window every fifteen minutes, including days whose data had not moved since the last pass. A per-day
reuse cache now skips that work, on both WHOOP 4.0 and 5.0/MG. This was the largest background drain on
Android and it was reported, measured and chased down with logs by @bartmuskala.

Low refresh, and Power saving where you can find it (#1430, #1431). A sub-option syncs hourly at any
charge instead of every fifteen minutes — fewer reconnections is the biggest saving on a WHOOP 4.0 — and
Power saving moved into More, with the battery threshold now reaching 35%.

Fewer diagnostics running forever. Shadow instrumentation from the R-R over-count investigation was
doing six sorts of a night's beats per night, on every affected strap, four times an hour. Two
measurements that had finished their job were retired, and what replaced them costs one pass.

Apple Health, and your ring

Automatic Apple Health write-back (#1432, thanks @MikaSchultes). Workouts can flow back into Apple
Health without a manual export.

Hourly step import (#1429). iPhone steps arrive hour by hour, with a 90-day backfill, instead of one
lump per day.

More of the Oura ring decoded, and read honestly (thanks @pipiche38). The ring's own breath rate is
decoded and shown as instrumentation rather than scored (#1384, #1450); its step features are decoded as
Tier-B instrumentation (#1359); the skin-temperature "worn" gate now allows for a ring whose heart-rate
and temperature sensors run on independent clocks, which was blanking the card entirely (#1467); and the
Rhythm view says "no data" outright on hardware that cannot produce the reading, instead of showing an
empty chart (#1360).

Honesty and accuracy

A large part of this release is numbers that were quietly wrong, or quietly guessed:

• A completed sync no longer reports itself as interrupted (#1466). A WHOOP 4.0 routinely ends a
  full night's offload on an idle timeout; NOOP called that "sync interrupted" even when the whole night
  had landed.
• Diagnostic exports report the strap that actually connected (#1451, #1464). Two logs from WHOOP 5
  straps were headed "WHOOP 4.0", and on Apple the header had never reported a model at all.
• Battery percent refreshes twice as fast while charging, because that is the one time the number
  moves while you are watching it.
• The strap reconnect survives suspension (#1421), and a 5.0/MG that does serve history no longer
  thrashes its link every two minutes (#1414, thanks @justinjor-bit).
• Re-scoring no longer silently skips Oura, watch and re-added straps (#1392, thanks @pipiche38).

Cross-platform correctness

@bhelm contributed roughly thirty fixes in this release, almost all of the same kind: places where
the Swift and Kotlin implementations of one calculation disagreed. Half-tie rounding in recovery traces,
FIT coordinates and connection durations; signed zero surviving a clamp; DST-spanning stress windows;
sleep-stage clipping; malformed UTF-8 in the Oura text decoders; JSON control characters in Android
backups; Unicode normalization of custom lab-marker keys. Individually small, collectively the reason
the two platforms produce the same numbers from the same bytes.

@vishk23 extended the golden decoder oracle past frame decode (#869) — and it immediately found four
places where a 32-bit narrowing on Kotlin would have silently discarded all history from 2038, or today
on a strap with a future-dated clock.

@terry-zeng1134 fixed the AltStore manifest's declared permissions (#1388), and @Duzafizzl built
out the Breathe protocol catalog with holds, session lengths and translations (#1390).

Thanks

To @bhelm, @pipiche38, @vishk23, @MikaSchultes, @Duzafizzl and @terry-zeng1134
for the code; and to @bartmuskala, @justinjor-bit and @pipiche38 for reports carrying logs,
screenshots and measurements — several of which found bugs no test was going to catch.

And a belated thank-you to @gdorgian (#1366), @riebschlaegerstar-sys (#1361) and
@pilleuspulcher-blip (#159), whose reports were fixed in v10.1.0 but went uncredited in that
release's notes.
