Summary

Closes #65. Check-ins and cheers previously reloaded complete Duel history, including embedded photos. This change synchronizes revisions and changed metadata, loads proofs when viewed, caches history per project/account/Duel, pauses inactive polling with backoff, and batches week-scoped wearable updates. Existing data and proofs remain in place.

realtime or reopen → one delta read → update isolated metadata cache
view proof → authorized photo read
edit note or points → patch supplied fields → preserve omitted photos

Reconciled with main after PR #64. Its view/history improvements remain; metadata proof counts also preserve the optimized badge calculation. Tests for the superseded full-history pagination loader are replaced by delta/SQL/browser coverage.

Evidence

• Before: realtime signals redownloaded full history/photos. After: the production browser fixture with 731 historical Check-ins makes one delta read for twenty signals, uses a 45-byte unchanged reopen response, and requests one photo when opening the gallery.
• Typecheck, lint, 164 tests and the disposable PostgreSQL migration/RLS suite pass on the reconciled code. Configured production build and browser flows pass, including offline reopening, remote deletion, proof-preserving note edits, profile-only updates and optimistic writes surviving stale reads. No page errors.
• Applied supabase/egress.sql through Supabase MCP on 2026-10-14 as migration 20261014175421_reduce_duel_egress_incremental_sync. All 118 live Check-ins and 10 proof-bearing records retain their complete pre-migration digest. Authenticated metadata retains all history without photo bytes; original proofs resolve and unchanged deltas are 48 bytes. Outsiders receive no metadata/sync heads, anonymous RPC execution is denied, RLS/realtime are enabled, and security-advisor findings are unchanged.
• Browser fixture evidence and rollout verification. Local fixture results are synthetic, not billed production measurements. Fresh GitHub CI and Vercel preview checks run on integration commit 3ed5fdb.

Merge Danger

Door: two-way. Reverting the client keeps original tables and proofs usable. The additive migration is already applied; it neither deletes nor rewrites existing progress or photos. No billing changes.

Blast Radius: synchronization. History reads, proof loading, caching, polling and Check-in patches change. Initial metadata retains full history for lifetime scores and streaks; backup exports resolve original proofs. PR #62 remains open and also touches store/profile integration.

Hosted multi-session load and interactive production flows remain unverified. Vercel MCP returns a team-scope 403 and the deployed app is behind Vercel Authentication; local production browser and live database checks are available above.
