Sleep awake selection and PDF V1 evidence

TRAINLOG_SLEEP_AWAKE_SELECTION_PDF_V1=PASS on 2026-09-24.

The Web now derives the agenda, selected-night heart-rate overlay, and vector PDF rows from one pure temporal projection. It retains every structured long_awake interval separately from point-in-time night_get_up events, medication intakes, and sleep ranges. Factual sleep intervals determine sleep duration when present. Otherwise the displayed Couché +45 minutes to Levé -10 minutes range supplies a presentation-only duration after subtracting the union of overlapping structured awakenings; no estimate is persisted.

One agenda row is the effective selection. A click updates the detail dates, editor snapshot, and HR context in memory without issuing a write. PDF preview and download receive the same one-entry snapshot, and all observations are recomputed from that subset. Before an explicit click, the active night or the first deterministically ordered row is the documented fallback.

Automated validation

  • Web targeted suites: 34/34 passed.
  • Complete Web suite: 208/208 passed.
  • npm run typecheck: passed.
  • npm run build: passed.
  • Embedded production bundle meson compile -C build: passed.
  • The tests cover multiple awakening intervals in agenda/HR projection, exact factual sleep duration, estimated duration with awakening subtraction, selection dates/HR identity, no write on selection, identical preview/export subsets, PDF interval geometry, medications, point markers, and no-HR fallback without an invented BPM curve.

Read-only real-data smoke

The rebuilt user Web service was exercised through real headless Firefox at http://trainlog.perf/analyse?section=sleep without a Sleep mutation.

  • The real 2026-09-23 → 2026-09-24 row contains no factual sleep interval; its displayed estimated band now reports 5 h 14 min 16 s, not —.
  • The real 2026-09-22 → 2026-09-23 row renders its structured awakening in both the agenda and the no-invented-HR detail overlay.
  • Selecting that row updates the detail inputs to exactly 2026-09-22 and 2026-09-23.
  • Firefox export produced one PDF page whose extracted text contains only 22/09/2026, au 23/09/2026, and 1 nuit; it contains no 24/09 row.
  • The selected-subset observation is Sommeil déclaré : 6 h, Longs réveils : 1, Siestes : 1, and Prises de médicaments : 7.
  • Raster inspection confirms the long-awake band remains visibly distinct inside the sleep timeline and point/medication markers retain their positions.

The change affects no database schema, synchronization artifact, frozen format, or Android behavior.
