TASK-birth-sky-followup-20260928 F4:
- pure timeline / seeded scatter / interpolation in lib/birth-sky/converge.ts;
drawBirthSky takes an optional frame (positions interpolated, alphas
multiplied) so the settled frame is the exported cover call for call
- lazy full-screen <dialog> overlay driven by requestAnimationFrame at
viewport x DPR; tap / click / Esc end it; reduced motion only fades
- data, serif and overlay chunk must all arrive inside the 3 s budget,
otherwise skipped silently; page.tsx wiring unchanged
- one sonner hint after it ends; dialog reveal variant (继续, is-reveal) removed
- DESIGN §17, VOICE, CHANGELOG, checklist, PROGRESS with verification

Product decision A (TASK-birth-sky-followup-20260928):
- every generation path writes subject.birthFingerprint (stored-row
fingerprint, same function as the chart page's profileFingerprint);
never into the evidence bundle the model reads
- GET /api/reports/:id compares on the server and returns only
report.coverSubject (subject id or null); legacy reports never get one
- report page shows the night cover above the body, paper cover alone on
the first printed A4 page; silent on any failure, no waiting state
- TS / JSON schema / Python contract accept the optional field
- BLOCKED T5 struck through; DESIGN §17, CHANGELOG, checklist, PROGRESS

After saveOnboardingPlace succeeds (and the next step is already set), the
new useBirthSkyReveal hook fetches /api/birth-sky?subject=self and paints
the cover; if that finishes within 3 s the chart page's dialog fades in
(600 ms, none under reduced motion) with 「继续」. Timeout or failure is
silent, no retry; closing touches only the reveal's own state. Home() gains
no useState/useRef; page.tsx only wires. Family profiles and profile edits
never trigger it.
Also caps the dialog image by viewport height (the percentage max-height did
not resolve inside the flex/grid cell), and completes PROGRESS, DESIGN §17,
CHANGELOG and the real-device checklist.

Report rows, report documents, jobs, sections and appendices carry no
birth-data fingerprint (request_fingerprint excludes birth data;
calculation_hash is an engine result hash or the markdown sha256). Per the
brief the cover is not shown rather than drawn from the current profile.
reportView, the report page and print styles are unchanged. BLOCKED.md lists
the evidence and two options for the product owner.

T1 scripts/birth_sky.py: real alt/az of the seven visible grahas (swe.calc_ut +
swe.azalt, geometric altitude, azimuth converted from swe's south origin to
north-east) and Yale BSC5 stars V<=4.0 (IAU 1976 precession); phase
day / twilight_morning / twilight_evening / night. Thin POST /api/birth_sky
registration in do_POST (no new handler method, no __new__).
T2 GET /api/birth-sky?subject=: birth truth read server side through
loadSubjectBirth + prepareChartViewProfile; zod contract; no billing, no
writes, no birth data in the response.
T3/T4 lib/birth-sky: sentence table, pure Canvas 2D drawBirthSky (night /
paper palettes from DESIGN tokens, east on the left, serif headline with
1.5 s font wait), PNG export via navigator.share or Blob + a.download.
Chart page prefetches and paints the cover once the chart is ok; the header
button appears only when the PNG is ready. Dialog is a lazy chunk.
T7 DESIGN §17, VOICE, CONTEXT glossary, CHANGELOG, real-device checklist.
