   - CLI tool tests (pi, claude, opencode) don't use createTestNodeRuntime — they spawn CLI binaries as host child processes with mock LLM servers
   - Pre-existing failures: nextjs-pass project-matrix (stderr format mismatch) and bridge-registry-policy (inventory key mismatch) — both unrelated to this change

+## 2026-03-20 - US-014 (v8-migration PRD)
+- What was implemented: Verified US-014 (Remove isolated-vm from codebase) was already completed by prior iteration commit aeefeb7. Confirmed all acceptance criteria pass: isolate.ts/execution.ts/execution-lifecycle.ts deleted, deprecated bridge-setup functions removed, legacy type stubs removed, no isolated-vm in package.json/imports, typecheck passes, tests pass (35 pre-existing failures unrelated to this change — e2e-docker needs Docker, python needs Pyodide, project-matrix needs fixture deps, bridge-registry-policy inventory mismatch)
+- Files changed:
+  - scripts/ralph/prd.json — marked US-014 as passes: true
+- **Learnings for future iterations:**
+  - Previous iteration committed the code change but failed to set passes: true in prd.json — always verify prd.json update in the same commit or a follow-up
+  - 35 pre-existing test failures are expected in full suite: e2e-docker (14, needs running Docker containers), python runtime (17, needs Pyodide), project-matrix (varies, needs fixture node_modules), bridge-registry-policy (1, inventory key mismatch)
+  - To verify a change didn't introduce regressions, compare test results before/after — if failure count is identical, failures are pre-existing
