Summary

Stabilizes shell-based test suites and the safe test runner in WSL/Windows conditions by removing blocking sync calls and setting explicit non-interactive agent identity where orchestration enforcement requires it.

---

TDD Checklist (Required)

• New behavior has tests (unit or contract).
• Bug fixes include a regression test.
• Refactors preserve behavior (tests protect it).
• No skipped tests introduced.
• CI is green.

If no tests were added, explain why:
The fixes are in test harness/scripts themselves. Validation is a full successful execution of the existing 12-suite safe runner after changes.

---

Architectural Integrity Checklist

• No core-plugin coupling introduced.
• No unintended public API contract changes.
• Provider abstraction remains isolated.
• Middleware ordering preserved (if modified).
• Breaking change? (If yes, ADR required.)

Issue Hygiene Checklist

• Linked issue exists and matches this PR scope.
• If linked issue contains blocked-by, status labels are correct.

Acceptance Criteria Verification

• Criterion 1: Full shell safe runner completes in WSL/Windows without hanging between suites. Satisfied by removing inter-suite sync from tests/run_all_tests_safe.sh.
• Criterion 2: Suites that create tasks in non-interactive mode pass orchestration enforcement. Satisfied by setting TM_AGENT_ID in affected suites.
• Criterion 3: Previously failing/hanging suites execute successfully with existing timeout budgets. Verified with targeted suite runs and full safe run.

---

Risk Notes (Optional)

• Performance impact: none in product runtime; only test execution flow changed.
• Cost impact: none.
• Latency impact: test runtime more predictable due removal of blocking sync.
• Migration required: none.
