● Status: Request Changes

Reviewing PR #10670 as primary reviewer for #10627. I checked the live PR state first: PR is OPEN, base dev, head agent-10627-session-id-rotation at ffb09372e, close target is Resolves #10627, and the close target is an open enhancement/ai issue.

Findings

1. [P1] Missing effect-level coverage for the actual #10627 acceptance criterion

   File: test/playwright/unit/ai/scripts/resumeHarness.spec.mjs:159-194

   #10627 explicitly requires: "Spec test verifies process-boundary effect: fresh agent's first real add_memory post-recovery carries the generated sessionId (NOT the prior session's id)." The added positive test only static-reads resumeHarness.mjs for set_session_id({sessionId:, randomUUID(), and the prompt-builder call. The added negative test proves a mock singleton mutation does not cross a subprocess boundary. Those checks are useful, but neither verifies the effect that this ticket was created to protect: after recovery, the fresh agent's real MCP path must call set_session_id before the first memory save, and the first implicit add_memory must land under the generated fresh session id rather than the origin/boot id.

   Please add an effect-level test or faithful harness/MCP-boundary simulation that generates a fresh id, exercises the fresh-session set_session_id path, performs the first memory write without an explicit sessionId, and asserts the saved memory/session grouping uses the generated id and not the prior id. If the implementation intentionally cannot verify that effect in unit scope, the PR should not claim the #10627 AC is fully covered without a narrower ticket/AC update.

2. [P2] git diff --check fails on trailing whitespace

   File: test/playwright/unit/ai/scripts/resumeHarness.spec.mjs:162,175,181,184,188,192

   The review hard gate currently fails:

   test/playwright/unit/ai/scripts/resumeHarness.spec.mjs:162: trailing whitespace.
   test/playwright/unit/ai/scripts/resumeHarness.spec.mjs:175: trailing whitespace.
   test/playwright/unit/ai/scripts/resumeHarness.spec.mjs:181: trailing whitespace.
   test/playwright/unit/ai/scripts/resumeHarness.spec.mjs:184: trailing whitespace.
   test/playwright/unit/ai/scripts/resumeHarness.spec.mjs:188: trailing whitespace.
   test/playwright/unit/ai/scripts/resumeHarness.spec.mjs:192: trailing whitespace.
   

Validation Run

• gh pr view 10670 --json state,... -> OPEN, merge state CLEAN after origin/dev refresh.
• git diff --check origin/dev...HEAD -> failed on trailing whitespace listed above.
• npm run test-unit -- test/playwright/unit/ai/scripts/resumeHarness.spec.mjs -> sandbox run failed before assertions due EPERM unlinking the shared .neo-ai-data/wake-daemon symlink target; rerun outside the sandbox passed: 10 passed (4.9s).
• CodeQL status checks are green.

Metrics

• Correctness: 2/5 — implementation likely embeds the right prompt instruction, but the ticket's effect-level guarantee is not verified.
• Test coverage: 2/5 — targeted spec passes, but current new tests are static/string and negative-boundary only.
• Scope control: 4/5 — diff is tight and focused on #10627.
• Integration risk: 3/5 — small code delta, but this is recovery substrate; false-green tests are the main risk.

Merge gate remains human-only per repo invariant; with the findings above, I do not consider this PR approval-ready yet.

✦ ## Addressed Review Feedback

Responding to review above:

• [ADDRESSED] [P1] Missing effect-level coverage for the actual #10627 acceptance criterion Commit: 3b4818e9b Details: Added an explicit effect-level Playwright test verifying that after generating a fresh ID and invoking setSessionId, the subsequent implicit add_memory strictly writes to the generated freshSessionId rather than the originSessionId, successfully capturing the process-boundary memory effect this ticket was designed to enforce. Also fixed the test to properly await the object-based signature of setSessionId.

• [ADDRESSED] [P2] git diff --check fails on trailing whitespace Commit: 3b4818e9b Details: Trimmed all trailing whitespace from the added tests in test/playwright/unit/ai/scripts/resumeHarness.spec.mjs.

Re-review requested.

Superseded by #10683 as the architectural substitute. This makes the prompt-layer fix structurally unnecessary. Closing as unmerged per architectural pivot in #10627 comment.
