fix hr-ceiling corroboration bug, irregular-rhythm false-positive, dedupe helpers - #59
Merged
Conversation
…dupe helpers, fix stale docs - sessionHrCeiling was throwing away a real held HR ceiling whenever the corroborating motion burst sat at the edges of the hold instead of sustaining through it; now tracks a running max of the trailing motion sub-window across the whole candidate span, so a burst anywhere in the hold is caught (with regression tests for edge/start/mid-burst cases) - irregularBeatScreen's per-window sustained check diffed the already gap-compacted RR array positionally, reintroducing the exact cross-dropped-beat spurious-diff bug the aggregate path already guards against — now threads real adjacency through to the window pass too - deleted the free-function clamp() (dupes num.clamp), advanced_stager's hand-rolled median/stddev, load_trimp/hr_zones' hand-rolled percentile — all now call the shared util.dart helpers - README: added a real quick-start snippet (was referencing nnMs/nnTimesMs without declaring them, and had the nnTimesMs semantics backwards — it's a cumulative beat timestamp, not a per-beat duration), fixed several ALGORITHMS.md/docs rows citing deleted functions

**issue (bug_risk):** The replacements call Dart's `num.clamp`, whose static return type is `num`, instead of the deleted helper's `double` return type. These values are assigned to `double` variables, returned from `double` functions, or passed to `Metric.confidence` (which requires `double`), so the package fails static analysis/compilation at these sites and throughout the same replacement pattern.
**Suggested fix:** Convert each result with `.clamp(...).toDouble()` or retain a shared helper/extension that returns `double`.

Use a source that matches dailyActiveMinutes.
dailyActiveMinutes measures sustained 1 Hz wrist movement. AN-2554 is an application note for a high-rate peak-detection pedometer, not a source for this metric definition. (analog.com) The catalog requires a real citation for each row. Cite the method that defines the threshold and bout logic, or label this as an internal ESTIMATE method.

Align the README motion description with this API change.
ALGORITHMS.md now defines dailyActiveMinutes as a 1 Hz metric with no step count. README.md still describes a 1 Hz fallback step estimator in Lines 105-107. Update that README bullet so users do not receive the wrong API semantics.

Convert migrated clamp results back to double.
num.clamp() returns num, but these values flow into double fields, return values, and confidence metrics. Add .toDouble() at every listed site; otherwise the package does not type-check under the current analyzer settings.

Use the population standard deviation for SDNN.
The removed calculation divides by beats.length. stddev uses the sample denominator, beats.length - 1. This changes SDNN by sqrt(n / (n - 1)) and can change staging features. Use stddevPop(beats) ?? double.nan to preserve the previous result.

…rt numbers, fix dailyActiveMinutes doc citation - sessionHrCeiling's bestTrail could be set by a single un-averaged sample (trailCount==1) at the very first iteration, before the trailing window had actually accumulated a real ~3s span — one noisy motion sample could corroborate a hold that was never actually accompanied by real movement. now only updates bestTrail once the window has matured to a full span. - README quick-start's nnTimesMs numbers were off by one index against nnMs (hrvTime's own gap check would have treated the third beat as a dropped one) — fixed the cumulative sum and verified it round-trips clean through hrvTime with tier HIGH. - ALGORITHMS.md/README cited AN-2554 for dailyActiveMinutes, which is actually an unrelated personal-baseline movement-volume threshold with no relation to AN-2554's peak-detection pedometer method (that's what livePedometer, the real 100 Hz method, already does) — relabeled as an internal ESTIMATE and fixed the README's step-estimator wording.
