Sleep Diary capture UX and black-screen correction evidence

Scope

This record covers the focused 0.1.4 Web correction and presentation tranche. It does not change Sleep Diary domain semantics, desktop schema v29, Android schema v26, synchronization, publication lifecycle, PDF semantics or any frozen exchange format.

Runtime diagnosis

The deployed bundle was run through http://trainlog.perf/analyse?section=sleep in Firefox 156 with an isolated synthetic XDG data directory. The browser reported isSecureContext === false and did not expose crypto.randomUUID. Clicking Ajouter for a bedtime event raised:

TypeError: crypto.randomUUID is not a function

The stack entered the addEvent state updater in web/src/routes/SleepDiaryWorkspace.tsx. React then unmounted the application tree, leaving an empty body. The router remained on the Sleep Analyse URL. There was no mutation request, HTTP status or response body because the exception happened while constructing the optimistic event. No unhandled promise rejection was present. Medication intake identity construction used the same unsupported API and had the same latent failure.

Correction

Sleep event and medication-intake identities now use crypto.getRandomValues, set the UUIDv4 version and RFC 4122 variant bits explicitly, and never fall back to Math.random. A section-local React error boundary keeps the Trainlog shell, header and navigation mounted and offers a retry card for unexpected future render errors. This boundary is defense in depth; it is not the black-screen fix.

The capture presentation now uses the existing Trainlog panel, quiet-action, primary-action and danger-action vocabulary. Dates, lifecycle badge and local save state form one night header. Morning/day appreciations, event creation, timeline, intake creation, notes and actions have explicit hierarchy. The medication catalog is a compact list whose creation form opens on demand and whose saved item becomes immediately selectable for an intake.

Validation evidence

  • Web TypeScript, all Vitest tests and the Vite production build pass.
  • Component regressions cover bedtime, sleep, long awakening, final get-up, nap and sleepiness, stable entry identity, advanced revisions, medication creation, intake creation, edit and delete.
  • Real Firefox against the production C server created two medications, two intakes and five events, then reloaded the same durable entry and revision.
  • Every captured mutation returned HTTP 200 with its expected JSON identity or revision response. The console error and unhandled-rejection collections remained empty.
  • The responsive layout had no document-level horizontal overflow.
  • The retained post-reload screenshot is evidence/sleep-diary-v1-final-firefox.png.

Private deployment evidence

The functional bundle was built from 915728cec4ffbb2c90eb3f4b47d349a6ebd17fe9. Its embedded desktop binary has SHA-256 e45c2fd8807dd9c28128206ee57e2869b64726397ae6072d521a903d3d4afdc9. Before the switch, the live schema-v29 database was backed up as trainlog-before-915728c97f420f824c7831024d61ee9c08645321.db, SHA-256 9579e1365164a082e328c4c5bc1ffc7b45bf234a1f5bf1812842837c8ecc05f7; its integrity check was ok and its foreign-key check was empty.

The versioned installation is ~/.local/share/trainlog/installations/915728cec4ffbb2c90eb3f4b47d349a6ebd17fe9. After the atomic user-bin switch and service restart, trainlog-web.service was active as PID 2322898, and /proc/2322898/exe resolved to that installation's libexec/trainlog. The deployed executable and footer both reported version 0.1.4.

Real Firefox 156 then used the actual deployed profile to create TestMed A 5 mg and TestMed B 25 mg intakes at 22:00, bedtime at 22:30, sleep from 23:00 to 03:00, a long awakening from 03:00 to 03:30, sleep from 03:30 to 06:30 and final get-up at 07:00. Reload retained entry sl_71b9c7a5-cabe-4d22-86fc-bde8a34590f9 at revision slr_c1e8f641-4db7-43f1-8a9c-e7ef15b2c1df, with five events and two intakes. All nine mutations returned HTTP 200. Browser console errors, network fetch errors and unhandled rejections were all zero. The exact 390×844 viewport had zero document overflow. No main merge, tag or release was created.
