three alignment fixes.

  • journalCorrelations had no lag, so an alcohol tag logged friday got compared against friday's readiness (thursday night). added journalTagLagDays like the numeric field map: behaviour tags +1, stress/poor sleep/sick stay 0. a lagged day with no journal row the day before is dropped, not counted as untagged. edge still only builds outcomes at journal dates, so lagged days drop there until that's widened. the rough-night card writes causes on the wake day, so on re-pin it has to store each tag at journalTagDayForNight(night.day, tag) or lag-1 tags pair with the next night.
  • sessionMorningEffects paired a session with the next row, so after a wear gap a later morning got banked as the next one, and the 28 day baseline was 28 rows. now uses calendarDays like the siblings.
  • multivariateAnomaly only built correlation rows from nights with all four features, so a sparse temp/resp column forced the identity and rhr up + hrv down counted twice. rows now only need tonight's kept features.

Summary by Sourcery

Correct journal, session, and anomaly alignment so correlations and effects use the appropriate calendar days, outcome timing, and available features.

New Features:

  • Align journal tag correlations with per-tag outcome timing, including helpers for storing retrospective night causes correctly.

Bug Fixes:

  • Prevent session effects from pairing sessions across missing calendar days or using row counts instead of calendar-day baseline windows.
  • Preserve multivariate anomaly correlations when only a subset of tonight's features is available, avoiding duplicated contributions from correlated features.

Tests:

  • Add regression coverage for lagged journal tags, sparse journal dates, retrospective night causes, session wear gaps, and sparse anomaly features.

Summary by CodeRabbit

  • Bug Fixes
    • Journal correlations now align behavior tags with the following day by default, while retrospective tags remain aligned to the same day. Outcomes without a journal entry for the relevant source day are excluded rather than counted as untagged.
    • Morning-effect analysis now pairs sessions only with the immediately following calendar day and uses calendar-day windows for baselines, avoiding misleading results across missing days.
    • Multivariate anomaly analysis can use baseline data when some features are missing, improving consistency when evaluating shared features.

📝 Walkthrough

Walkthrough

The changes update journal tag-date matching, session morning pairing and baseline windows, and correlation sampling for multivariate anomalies with missing features. Regression tests cover each behavior.

Changes

Journal Tag Alignment

Layer / File(s) Summary
Tag lag mapping and correlation matching
lib/src/onehz/human/coaching.dart, test/onehz/coaching_test.dart
journalCorrelations uses a configurable tag lag map. A lagged tag is read from the corresponding earlier date, and an outcome is skipped if its source date or journal row is missing. Tests cover next-day matching, sparse journals, and explicitly disable lag alignment in other statistical tests.

Session Morning Effects

Layer / File(s) Summary
Calendar-day pairing and baseline window
lib/src/onehz/human/session_cost.dart, test/onehz/an_training_human_test.dart
sessionMorningEffects only pairs a session with the next calendar day. Its baseline window uses preceding calendar days rather than a fixed number of rows. Documentation and a regression test cover date gaps.

Sparse-Feature Anomalies

Layer / File(s) Summary
Correlation sampling for kept features
lib/src/onehz/wellness/anomaly.dart, test/onehz/wellness_test.dart
Baseline collection retains oriented rows with missing features. Correlation estimation selects rows with values for every kept feature. A regression test compares anomaly results for full and sparse feature inputs.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Suggested reviewers: svssathvik7

Merge Risk: 🟡 Moderate · up to c9a05

A behavior tag spelled late_meal may still be matched against same-day outcomes instead of next-day outcomes. Session pairing may also quietly fall back to row-based logic when date labels are not ISO dates. Resolve or confirm both before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c9a05

The changes remain focused on analytics calculations, with no identified increase in access, privileges, or data exposure. Caller compatibility deserves attention because lagged journal analysis requires outcomes beyond the journal dates themselves.

Retained concerns
No architecture-level concerns identified.

Reviewer's Guide

The PR fixes three alignment issues: journal tags now map to the appropriate outcome night with explicit missing-source handling, session effects use calendar-day adjacency and windows, and anomaly correlations tolerate sparse features without double-counting shared deviations.

📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Pin tagLagDays explicitly in tests that use non-date labels.

This test and the other tests that use d0, d1 labels and the coffee or x tags do not pass tagLagDays. They pass today only because those tags are not in the default lag map and fall back to lag 0. If someone adds coffee to journalTagLagDays, these tests will fail with unclear errors. Pass tagLagDays: const {} in the tests at lines 352, 402, 488, 556, 608, and 629 to keep them independent of the default map.
