…ne guard Hoists the baseline-dispersion refusal (readiness_composite.dart:207-227) into foundations/baseline.dart as a standalone, reusable predicate. Prerequisite for M5, where the same guard is needed on illness_cusum.dart and anomaly.dart once masking shortens their baseline windows -- NOT added to either of those here, since that would change a shipped number for a single-device user whose quantized baseline has SD strictly between 0 and 1, which a milestone whose gate forbids a kAlgoVersion bump must not do. Byte-identical refusal string, by construction: the extracted function is the inline body verbatim (quantum<=0 -> false; else sd==null or sd<quantum), and the call site still recomputes sd for the message so the string is untouched. No new call site added anywhere. test/dispersion_guard_test.dart pins the three cases from spec-m0-m2.md §0.1 (SD 0.577 refuses, SD>=1 does not, quantum 0 never refuses) plus one readinessComposite integration case reusing the existing 14-night sub-bpm baseline from wellness_test.dart, asserting the refusal string is unchanged. dart test: 632 passed, 0 failed (6 pre-existing skips, all whoop_hist.jsonl-gated -- fixture absent in this environment). dart analyze clean. No golden churn.
Reviewer's GuideExtracts readiness’s baseline-dispersion-below-quantum check into a reusable foundation predicate, preserving the byte-identical refusal behavior and intentionally deferring adoption by illness/anomaly paths; focused unit and integration tests pin the semantics.

## Individual Comments
### Comment 1
<location path="lib/src/onehz/wellness/readiness_composite.dart" line_range="221-222" />
<code_context>
// quantized series already means ≥ 1 step of spread.
- final sd = stddev(base);
- if (sd == null || sd < inp.quantum) {
+ if (dispersionBelowQuantum(base, inp.quantum)) {
+ final sd = stddev(base);
refusals.add('${inp.label}: baseline_dispersion_below_quantum:'
'sd=${sd == null ? 'null' : round6(sd)},'
</code_context>
<issue_to_address>
**nitpick (performance):** On every refusal, `dispersionBelowQuantum` computes `stddev(base)`, and the next line computes `stddev(base)` again to format the refusal message, doubling the O(n) scan of the baseline.
**Triggers:** When a quantized input has dispersion below its quantum.
**Suggested fix:** Return the computed dispersion alongside the predicate result, or expose a helper that lets the caller reuse the already-computed standard deviation.
</issue_to_address>
### Comment 2
<location path="test/dispersion_guard_test.dart" line_range="44-45" />
<code_context>
+ final m = readinessComposite([rhrInput(52.0, base)],
+ minInputs: 1, minWeightSum: 0.0);
+ expect(m.present, isFalse);
+ expect(m.note, contains('RHR: baseline_dispersion_below_quantum:'));
+ expect(m.note, contains('quantum=1'));
+ });
+ });
</code_context>
<issue_to_address>
**issue (testing):** The integration test does not verify the complete refusal string despite claiming to pin it: it only checks the prefix and `quantum=1`, so changes to the SD value, sample count, separators, or trailing punctuation pass silently.
**Triggers:** When the refusal message changes in any part other than the asserted prefix or quantum field.
**Suggested fix:** Assert the complete expected note, including `sd=0.267261` and `n=14`.
```suggestion
expect(m.note, equals('no readiness inputs present — "—" (never imputed). '
'Refused: RHR: baseline_dispersion_below_quantum:'
'sd=0.267261,quantum=1,n=14.'));
```

- Around line 16-18: Add an exact-equality boundary test for
dispersionBelowQuantum using values such as [0, 1, 2] with quantum 1, and assert
isFalse to verify strict sd < quantum behavior. Keep the existing
above-threshold case unchanged.
- Around line 44-45: Update the assertion in the byte-identical refusal
diagnostic test to compare m.note against the complete expected refusal string
using exact equality, including the standard deviation, separators, item count,
punctuation, and quantum value; remove the partial contains assertions.
