 - **Required team mode also blocks Copilot CLI's skill tool.** Re-run `gstack-team-init required` to upgrade the project hook.
 - **`gstack-qa-evidence capture` prints a `revalidate` list after your inputs change**, naming the probes to rerun on current inputs before `materialize`; `materialize` says its verdict is final for that report root, so rerun the listed probes first.
 - **/gstack-upgrade asks you to paste the absolute path Step 2 prints**; every later step checks it is inside gstack's checkout before running git.
+- **Browser setup names the platform when Aside is absent:** the probe prints `NEEDS_ASIDE: <OS>` (was `NEEDS_ASIDE`), and the macOS-only download pitch trusts that line instead of re-checking the OS. `GSTACK_PLATFORM` overrides it for tests and unusual hosts; set it in your shell, never a project `.env`.

Target outcome: byte-identical listings across runs and machines so script and review diffs stay quiet. Do-nothing cost: spurious diffs in every comparison. The plan addresses the pain directly, not a proxy.\n- **0B Existing code leverage.** This fixture repo contains only PLAN.md and CLAUDE.md, so the listing path, registry and test harness could not be inspected. The plan reuses the existing listing path rather than rebuilding it. Marked unknown for the substantive review.\n- **0C Dream state.** Current: enumeration-order output. This plan: one deterministic sort before render. 12-month ideal: all user-visible registries render in stable order. This plan moves toward it.\n- **0E count.** Estimated two changed files (listing source, tests). Estimate only, since the code is not in this checkout. Below every threshold. Category is fix/refactor, no overlap.\n\n**Audit record and provenance**\n\n| Field | Value |\n|---|---|\n| question_id | plan-ceo-review-mode |\n| user_choice | HOLD SCOPE |\n| recommended | HOLD SCOPE |\n| auto_decided | true |\n| session_id | 200041-1791092671-91ee5553 |\n\nBoth the handoff command and the question log exited cleanly.\n\n**Deferred per your instruction**\n\n- The Office Hours offer was not raised. The design doc check found none for this branch.\n- The skill-start output carried a one-time setup prompt to add skill routing rules to CLAUDE.md. Not raised, and plan mode forbids that edit and commit anyway.\n- The remaining HOLD SCOPE route (0G complexity check, 0I temporal interrogation, Sections 1 through 11, the review report) was not run. No plan file was written and ExitPlanMode was not called, since there is no review report to gate on.\n- Skill-end telemetry was not run because the workflow did not complete. Telemetry is off in this session, so nothing is lost.\n\nNext step when you are ready: re-invoke the review with HOLD SCOPE as the settled mode.

For this invocation,\nI want only the review-mode decision; I will handle optional Office Hours and\nsetup separately, and run the substantive review later. No review mode has\nbeen selected. For this mode-only handoff, use the full selected mode name in\nthe normal audit record's user_choice and recommended fields and in the skill's\nnormal mode handoff line.
