- shared/types.ts: single wire contract (type-only) used by both halves
- host/: services (contracts), pricing (token-meter), fold (incremental fold
+ retention), snapshot (build + event turn/step attribution), index (RPC)
- client/: i18n, styles, format, categories, viewkit (shared deps),
cache (per-session stale-while-revalidate), components/* (one module per
component), view (composition root), index (plugin entry)
- first-screen: initial render seeds from the session cache, polling pauses
while the tab is hidden (resume + immediate fetch on visible), and a
transient fetch error never blanks already-visible data
- build.mjs: bundle:true for both halves (react external in the client
bundle); the client half is now covered by tsc --noEmit for the first time
