types: improve type safety in mobile - #4211
Conversation
Replace unsafe type casts with discriminated unions and type guards in the mobile workflow runner, WebSocket service, and graph editor store. - WorkflowRunner: add WorkflowMessage discriminated union and isWorkflowMessage type guard, replacing 8 `as unknown as` casts with narrowed `msg as JobUpdate` etc. after a single entry guard. Preserves access to wire-only fields (error_message, suspension_reason) from the raw message record. - WebSocketService: narrow `send` parameter from `unknown` to `Record<string, unknown>`. - GraphEditorStore: construct WorkflowGraphInput explicitly instead of casting through unknown, eliminating 5 `as unknown as` casts.

CI is failing — typecheck and quality gate are red. PR #4212 (same base SHA 021ec36) passes typecheck, confirming these failures are introduced by this PR, not pre-existing.
The type safety improvements look correct in direction (discriminated unions, proper type guards, eliminating as unknown as casts). Please fix the typecheck errors and push an update.

Net result: -9 lines, zero casts in the message handler (down from 8 in the original code and 7 in the first revision).

Intersect protocol types (JobUpdate, NodeUpdate, NodeProgress) with Record<string, unknown> so the union is assignable to the type guard's parameter type. Remove the catch-all union member that prevented switch-case narrowing. Access properties directly on the narrowed msg variable instead of through intermediate casts.

The code changes look correct — replacing as unknown as double casts with proper type guards and explicit object construction is a real improvement.
However, the Quality Gate CI checks (typecheck, test-app, test-packages, lint, build) did not run on this PR — only CodeQL/Analyze ran. Cannot merge without a full CI pass.
The base SHA (021ec367) is also behind current main — please rebase onto main to trigger a full CI run. Note that PR #4212 (dead code removal) was just merged and removed some mobile types from ApiTypes.ts, which may cause merge conflicts with this PR's changes to the same file.

Code changes look correct — the discriminated union type, type guard, explicit object construction, and narrowed send() parameter are all sound improvements. No conflicts with recently merged PRs.
However, the Quality Gate CI (lint, typecheck, test-app, test-packages) never ran — only CodeQL/Analyze. The PR's base is stale (021ec367 vs current main). Please rebase onto main to trigger the full CI pipeline. No merge conflicts are expected since the touched files haven't changed on main.
