Summary

Two dead/partially-dead subsystems identified during WI-075 post-gate audit.

1. src/process/supervisor/ (10 files, zero external callers)

No code outside the supervisor/ directory imports getProcessSupervisor(),
createProcessSupervisor(), or any other export from this module.

Files:

• src/process/supervisor/index.ts (barrel + singleton)
• src/process/supervisor/supervisor.ts (implementation)
• src/process/supervisor/supervisor.test.ts
• src/process/supervisor/registry.ts
• src/process/supervisor/registry.test.ts
• src/process/supervisor/types.ts
• src/process/supervisor/adapters/child.ts
• src/process/supervisor/adapters/child.test.ts
• src/process/supervisor/adapters/env.ts

Action: Delete entire directory.

2. src/providers/ (5 files, partially dead)

The original disposition marked all 10 files GUT. WI-069 reduced to 5 files. Of the
remaining 5:

Dead (zero external callers):

• src/providers/github-copilot-models.ts — GitHub Copilot model catalog
• src/providers/github-copilot-models.test.ts — tests for above
• src/providers/github-copilot-token.ts — Copilot token management
• src/providers/github-copilot-token.test.ts — tests for above

Live (3 external callers):

• src/providers/kilocode-shared.ts — exports KILOCODE_BASE_URL and
  KILOCODE_DEFAULT_MODEL_REF, imported by:
  • src/commands/onboard-auth.credentials.ts
  • src/commands/onboard-auth.models.ts
  • src/commands/onboard-auth.config-core.ts

Action:

• Delete 4 dead github-copilot files
• Evaluate kilocode-shared.ts — if the onboard-auth commands that use it are themselves
  dead or will be modified during rebrand (M4), the constant can be inlined or moved to
  the consuming files. Otherwise keep.

Verification

• src/process/supervisor/ directory deleted
• 4 dead github-copilot files deleted from src/providers/
• kilocode-shared.ts evaluated and resolved (inlined, moved, or kept)
• pnpm build passes
• pnpm test passes
