- replace the hardcoded timeout switch with an engine that iterates registered handlers
- extract the timeout logic into handlers/timeout.ts and add handlers/env.ts that defers env as non-transparent
- thread a partial-evidence bag so the engine exception log retains handler-derived values like innerCommand
- add CONTEXT.md with the transparent vs non-transparent wrapper glossary
- record ADR 0002: env always defers to the AI judge and is never unwrapped
