Review proxy for sleepypod#840. Do not merge.

Summary by CodeRabbit

  • New Features
    • Calibration profiles now include a setting for the minimum signal score required to report a heart rate. Lower scores can result in no estimate.
    • Local fitting can save replay readings and set a minimum coverage requirement when ranking candidates.
    • Calibration reports now show coverage and error evidence across tuning, validation, and holdout data.

📝 Walkthrough

The pull request adds a configurable minimum peak score for heart-rate estimates and exposes it in calibration controls. It also changes local-fit metrics and candidate ranking, adds an option to save replay readings, and updates calibration locale catalogs.

Changes: Configurable heart-rate threshold

Layer / File(s) Summary
Threshold configuration and signal processing
modules/common/biometrics/manifest.v1.json, modules/common/biometrics/signal.py, modules/piezo-processor/test_shared_signal.py, src/biometrics/algorithms/registry-core.ts
The heart-rate configuration adds minimumPeakScore, defaulting to 0.4 and constrained to 0.1–0.8. The estimator uses this value to reject weak peak scores. Tests cover threshold behavior and invalid values.
Calibration control and catalog updates
src/components/biometrics/Calibration/*, src/lib/i18n/locales/*, src/components/biometrics/Calibration/tests/BiometricCalibration.test.tsx, src/demo/biometrics/worker-build.json
The calibration profile adds a slider for the threshold. Locale catalogs add or update calibration, evidence, and backtest messages. The backtest display test expectation and worker build hash also change.

Local-fit candidate evaluation

Layer / File(s) Summary
Metrics and candidate ranking
scripts/biometrics-local-fit/report.ts, scripts/biometrics-local-fit/report.test.ts
Reports add own-support MAE and reference coverage alongside common-support metrics. Ranking first applies the tuning coverage floor, then compares tuning and validation own-support MAE. Tests cover coverage-floor behavior and holdout metrics.
Fit options and replay-reading output
scripts/biometrics-local-fit/cli.ts, scripts/biometrics-local-fit/fit.ts, scripts/biometrics-local-fit/README.md
The CLI accepts --min-coverage and --save-readings. When reading output is enabled, each replay writes a JSON file containing cohort, configuration hash, dataset side, and readings. The README documents these options and report fields.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Merge Risk: 🔵 Low · up to 1e3d2

Fit users can receive a misleading ranking from an invalid coverage option, and Spanish users see the new control in English. These bounded issues warrant fixes or explicit acceptance before merging.

Explanation

The title clearly identifies the main change: adding a heart-rate estimator guard. It is concise and related to the pull request objectives, although the review prefix and issue reference add minor noise.

Full details: Docstring Coverage

Explanation

Docstring coverage is 37.50% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 16 functions across 10 files. (6 skipped: 6 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Validate --min-coverage before passing it to rankCandidates.

Number(flags['min-coverage']) returns NaN for non-numeric input, such as --min-coverage 75%. Every comparison coverage >= NaN is false. All candidates then fall below the floor, so the ranking silently loses its coverage filter. Also, ranking.json stores minimumCoverage: NaN, which JSON.stringify writes as null.

A user can pass 75 instead of 0.75. That value is also accepted and fails every candidate.

Reject values that are not finite numbers in the range 0 to 1.

The check also runs after the replays finish. Move it to the start of fit so a bad value fails before a long run.

Translate the new threshold control.

Both the slider label and its explanation have empty msgstr values. Spanish users cannot read this new control in Spanish, although the adjacent profile controls are translated. Add Spanish translations for both entries.

Also applies to: 2391-2393
