Fix Types

Workflow

1. Serial: run bun run typecheck / tsc / npx tsc once. Capture the full error list — this is the shared input everything else partitions from.
2. Serial — partition: group errors by file. Errors in shared type/interface definition files (e.g. types.ts, a module's interfaces.ts) are the OVERLAP case (workflows/parallel-execution.md §2) — fix these first, they're the dependency root for everything else.
3. Serial: fix the shared-type-def errors (wave 0). Re-run typecheck to confirm the shared contract is correct before fanning out.
4. Parallel (wave 1, ≤3-4/batch, per workflows/parallel-execution.md §1/§4): print the Parallel Execution Matrix (file/cluster → owns → depends on wave 0 → verify), then spawn one cook-worker (haiku or sonnet via model param) per remaining file or zero-cross-reference cluster (tier by fix complexity — mechanical type-annotation fix → haiku; logic-affecting fix → sonnet). Each owns exactly its file(s); brief = that file's error list + acceptance criterion "typecheck clean for this file, no any used to silence it."
5. Serial (wave 2): final typecheck. Zero errors → done. New errors from a fix → loop to step 4 for the affected file only (bounded: 3 cycles, then escalate per Verification Gate — do not loop indefinitely).

Rules

• Never use any just to pass the type check.
• Print the Parallel Execution Matrix before step 4's fan-out.
