TASK-birth-sky-polish-20260928.
- P1: chart page dialog shows only the picture on a dimmed stage, 「保存图片」 below, icon × in the corner.
- P2: BFF returns one server-built `caption` (「1994年5月18日 07:40 · 杭州」); printed under the fact line in all three places; adopted time adds 「 · 校正后」.
- P3: convergence 3 s + words 2.5 s + fade 1 s; settled frame still equals the exported cover.
- P4: redeem paywall no longer opens when the starter home appears; first send refused for credits opens it, later ones open billing; convergence dialog portalled to <body>. BUG-1080 investigating (Chrome repro rules out the overlay covering the convergence).

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.

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.
