Marc-André BombeckandClaude Opus 4.8 77a652a47c feat(cycle): cycle-phase correlation insight + Coach phase dimension
Add the menstrual-cycle phase as a channel in the existing FDR-guarded
correlation machinery, the same way rated mood factors were folded in —
no new statistics, the same Welch + Benjamini-Hochberg pipeline, the same
day floors and q = 0.10 gate.

Two complementary mechanisms, both confined to a gender-gated surface:
- a categorical luteal-vs-follicular contrast per outcome metric (resting
  heart rate, HRV, sleep, steps, weight, basal/wrist/skin temperature),
  surfacing one headline finding (resting-heart-rate-by-phase, falling
  back to HRV); and
- the continuous phase ordinal folded into the lagged-Pearson matrix.

Phase never reaches the general correlations route — the temperature
channels held out of the general matrix are un-blocked only here, behind
the cycle gate, so a reproductive inference can never leak onto a
non-gated surface. Every row shows n, effect size, p and q; nothing is
fabricated on thin data and nothing is framed as causal.

Surface it through a new gated GET /api/cycle/insights and a drop-in
card that mirrors the mood-factor crosstab.

Add a cycle dimension to the Coach snapshot: current phase + day-of-cycle,
the next predicted event (period range + confidence + method, fertile
window goal-gated), and the headline phase finding — present only for a
cycle-enabled account, so a non-cycle snapshot is unchanged. A new ground
rule keeps the Coach descriptive: never contraception-grade, never a
"safe day" claim.

OpenAPI regenerated; phase-correlation + snapshot-inclusion tests added;
copy localised across all six locales.

docs/ — internal reference + operator playbooks

The user-facing documentation lives at https://docs.healthlog.dev — that's the canonical surface for self-hosting guides, integration walkthroughs, AI-provider setup, and the doctor-report workflow.

The files in this directory are the internal operator playbooks, audit notes, and machine-readable specs that ship alongside the source:

  • api/ — the OpenAPI 3.1 spec for the native-client subset (iOS DTO codegen target). See api/README.md for the preview commands.
  • ops/ — backup / restore + encryption-key-rotation playbooks. These are the runbooks an operator reaches for during an incident.
  • self-hosting/ — horizontal-scaling notes (HEALTHLOG_PROCESS_TYPE=web|worker|all) and the deploy-pipeline recipe. Routine install steps stay on docs.healthlog.dev.
  • migration/ — release-by-release migration notes. Read the entry for the version you're upgrading from.
  • audit/ — per-release audit summaries archived for forensic traceability.
  • apple-store-connect-checklist.md — the iOS submission gate.
  • doctor-report.md — PDF generator design notes.
  • codex-protocol-spec.md — Codex / ChatGPT OAuth protocol reverse-engineering notes.
  • ui-guidelines.md — UI / a11y house style.
