/**
|
||||
* state-machine-runtime-failures.test.ts — Tests for auto-loop runtime failures,
|
||||
* infrastructure errors, stuck detection, session management, merge conflicts,
|
||||
* concurrent access, and race conditions.
|
||||
*
|
||||
* These tests use mocked LoopDeps and AutoSession to exercise the auto-loop
|
||||
* error handling paths without requiring real LLM sessions or network access.
|
||||
*
|
||||
* Coverage gaps filled:
|
||||
* 1. Infrastructure error detection and immediate stop (ENOSPC, ENOMEM, etc.)
|
||||
* 2. Consecutive error graduated recovery (1st → retry, 2nd → cache flush, 3rd → stop)
|
||||
* 3. Stuck detection: same error repeated, same unit 3x, oscillation A↔B
|
||||
* 4. Session lock validation: compromised, pid-mismatch, missing-metadata
|
||||
* 5. Session creation timeout (NEW_SESSION_TIMEOUT_MS = 30s)
|
||||
* 6. MergeConflictError stops auto-loop
|
||||
* 7. Max iteration safety valve
|
||||
* 8. s.active race: pause signal during unit execution
|
||||
* 9. Filesystem mutation during dispatch cycle
|
||||
* 10. Worktree disappearance detection
