A full reconcile is ~2N gitea calls (deps + timelines per issue). Every agent
tool call (query_project) was doing a fresh one; the UI reconcile and the agent
didn't share anything. Now a single in-memory snapshot cache backs both.
- gitea.ts: getSnapshot(client, { maxAgeMs }) — reads within the window reuse the
cache; maxAgeMs:0 forces fresh. invalidateSnapshot() drops it. The explicit UI
reconcile forces fresh (and warms the cache); agent tool calls tolerate a 30s
TTL to stay responsive; applyChange + createIssues invalidate so the board and
forecast reflect the write immediately.
- model.ts: query_project reads getSnapshot (30s TTL) instead of reconciling live.
This is the SQLite mirror's cache semantics in memory — rebuildable, the durable
truth stays in gitea (purity split, D4). Persistent SQLite (offline + instant
boot) is a separate slice: Electron 34's Node 20 has no node:sqlite, so it needs
better-sqlite3 + electron-rebuild or sql.js/WASM — deferred as its own decision.
Verified: desktop typecheck clean, 14 fixture e2e green, live Reginald still
answers correctly from the cache (writes invalidate → board stays correct).
