Hardcoded model IDs (claude-sonnet-4-20250514, claude-opus-4-20250514) were scattered across 7+ files as fallbacks. These were stale after the CLI update to v2.1.73 which resolves aliases to the new model IDs (claude-sonnet-4-6, claude-opus-4-6).

  • Add src/lib/model-ids.ts with CLAUDE_MODELS + DEFAULT_MODEL_ID (client-safe, no fs/db imports — avoids Next.js bundling errors)
  • provider-resolver.ts: import + re-export from model-ids.ts, replace hardcoded envModels and toAiSdkConfig fallback
  • model-context.ts: derive context window map from CLAUDE_MODELS (import from model-ids.ts to stay client-safe)
  • skills/search/route.ts: derive MODEL_MAP from CLAUDE_MODELS
  • checkin-processor.ts, onboarding-processor.ts, media/jobs/plan/route.ts: use DEFAULT_MODEL_ID for last-resort fallback
  • Fix chat/page.tsx status bar showing SDK-resolved wire ID
    (e.g. "claude-opus-4-20250514") instead of the user's selected model.
    Aligns with useSSEStream.ts which already had the correct priority.
    One place to update when new models release.

Hardcoded model IDs (claude-sonnet-4-20250514, claude-opus-4-20250514)
were scattered across 7+ files as fallbacks. These were stale after the
CLI update to v2.1.73 which resolves aliases to the new model IDs
(claude-sonnet-4-6, claude-opus-4-6).

- Add src/lib/model-ids.ts with CLAUDE_MODELS + DEFAULT_MODEL_ID
  (client-safe, no fs/db imports — avoids Next.js bundling errors)
- provider-resolver.ts: import + re-export from model-ids.ts, replace
  hardcoded envModels and toAiSdkConfig fallback
- model-context.ts: derive context window map from CLAUDE_MODELS
  (import from model-ids.ts to stay client-safe)
- skills/search/route.ts: derive MODEL_MAP from CLAUDE_MODELS
- checkin-processor.ts, onboarding-processor.ts, media/jobs/plan/route.ts:
  use DEFAULT_MODEL_ID for last-resort fallback

One place to update when new models release.

When Claude runs a long script, the SSE connection can be silently
dropped by transport layers (OS TCP stack, Electron internals, HTTP
idle timeouts). Previously this caused the stream to appear "completed"
with partial content and no error message.

Two-part fix:

Server-side heartbeat (claude-client.ts):
- Send keep_alive SSE events every 30s independently of SDK activity
- Prevents intermediate layers from considering the connection idle
- Timer properly cleaned up in all exit paths including cancel()

Client-side detection (useSSEStream.ts + stream-session-manager.ts):
- Track whether the server's 'done' SSE event was received
- If reader finishes without 'done', treat as connection drop
- Show "Connection lost" error and clear stale SDK session
- Flush residual SSE buffer after reader signals done

i18n (en.ts + zh.ts):
- Add streaming.connectionDrop translation key

chat/page.tsx used statusData.model (the SDK's resolved wire ID like
claude-opus-4-20250514) instead of statusData.requested_model (the
alias the user selected). This caused the "Connected (...)" status
to flash a stale/misleading model ID.

useSSEStream.ts already had the correct priority — this aligns
chat/page.tsx to match.
