A bundle of v0.16 platform work landing on top of the SvelteKit viewer.
Brings in 7 commits across docs, backend infra + features, frontend
plumbing, the live diashow, all UI surfaces (with dark mode), and a
viewer rebuild.
Headline features:
- Live diashow with two-queue policy (live drains first, shuffle as
fallback) and pluggable transitions. Design: docs/CONCEPT_DIASHOW.md.
- Dark mode: 'system' / 'light' / 'dark' preference, picked in the
onboarding step + the Account page, applied via Tailwind v4
class-based dark variant with FOUC guard.
- Host/Admin PIN reset with one-time PIN modal; admin may also reset
host PINs. Hosts may demote other hosts.
- Per-user dynamic storage quota enforced on upload + live widget in
My Account and on the upload screen. Toggleable per-area.
- All rate-limits + quotas individually toggleable from the admin
config UI (rendered as switches + a privacy_note textarea).
- Mobile-first gestures: long-press → context sheet, double-tap to
like with heart-burst. Buttons stay as desktop equivalents.
- Data mode (Saver vs Original) per device, applied across feed,
lightbox, and diashow.
- Per-event Datenschutzhinweis admin-editable, live-refreshed on all
clients via SSE event-updated.
- /api/v1/upload/{id}/original endpoint, /me/context + /me/quota.
Hardening (latent issues from the long-term review):
- Startup recovery for stuck compression / export jobs after a crash.
- Hourly cleanup of expired sessions + cold rate-limiter HashMap keys.
- ffmpeg 120s timeout with kill_on_drop (no more permit leaks).
- Per-user IndexedDB upload queue (no more cross-user leak on shared
devices); IDB schema bumped to v2.
- SSE reconnect uses exponential backoff (no more retry storm).
- PIN lockout no longer escalates — attempts reset when the cooldown
expires.
- soft_delete is now transactional and decrements total_upload_bytes
so quotas don't drift.
- pin-reset SSE handler filters by user_id so a host resetting Anna's
PIN doesn't clear Bob's cached PIN.
- Privacy note shown preformatted; admin-editable, ≤16 KiB cap.
Docs:
- New: FEATURES.md (role matrix), USER_JOURNEYS.md, IDEAS.md,
CONCEPT_DIASHOW.md, backend/migrations/README.md,
frontend/src/lib/README.md.
- Refresh: PROJECT.md, README.md, TEST_GUIDE.md, the two existing
CONCEPT_*.md banners.
- PROJECT.md, README.md, TEST_GUIDE.md: status line refreshed; rate-limiter
doc-vs-code drift fixed; HTML export section rewritten for the SvelteKit-
static viewer; SSE event names + new events documented; config seed block
extended with planned toggles + privacy_note; decision log entries added.
- docs/CONCEPT_HTML_VIEWER.md, docs/CONCEPT_MOBILE_UI.md: banner the design
intent as shipped; point at the source-of-truth code paths.
- docs/CONCEPT_DIASHOW.md: planned-then-shipped design for the live diashow
(two-queue policy, pluggable transitions, data-mode aware).
- docs/FEATURES.md: capability matrix by role (Guest / Host / Admin) plus
prose per area (auth, posting, feed, moderation, admin, export, gestures,
data mode, quotas, privacy note, extensibility).
- docs/USER_JOURNEYS.md: step-by-step flows for every supported scenario,
including PIN reset by host, data mode, privacy note, gestures, and the
admin toggles.
- docs/IDEAS.md: speculative extensions (global diashow, reactions,
multi-tenancy, animation pack, etc.) — explicitly out of v0.16 scope.
- backend/migrations/README.md, frontend/src/lib/README.md: codify the
"never edit a shipped migration" rule and the lib/ conventions
(one store per concern, gestures via actions, sheets via ContextSheet,
transitions as drop-in components).
