test(outside-plan-disabled): compare named record timestamps as instants; negated authorship is not a current claim

The repair rerun named the seeded record by its ISO second
(2026-09-29T16:58:52Z vs .727Z) and said 'I did not write'; both were
misread as a foreign timestamp and a current write.

Re-enable: `gstack-config set codex_reviews enabled`.\n\n**Branch taken:** Disabled — the terminal branch. Per OUTSIDE-PLAN.md this is an intentional opt-out, not a provider failure, so I did **not**:\n- construct the plan-review prompt\n- invoke the `codex exec` CLI\n- dispatch a Claude `Plan` subagent as native fallback\n- ask about outside findings or run Cross-model tension\n\n**Persistence:** The guarded command re-read the config in a fresh shell (still `disabled`) and appended this record via `gstack-review-log` (exit 0), confirmed via `gstack-review-read`:\n\n```json\n{\"skill\":\"codex-plan-review\",\"timestamp\":\"2026-09-29T17:00:15Z\",\"status\":\"skipped\",\"source\":\"none\",\"host\":\"claude\",\"outside_provider\":\"codex\",\"outside_status\":\"disabled\",\"phase\":\"plan-review\",\"commit\":\"\"}\n```\n\n(`commit` is empty because this directory is not a git repository — the command's `|| true` guard handled that as designed.)\n\n**Outside-review attribution for this plan:**\n- Outside provider: codex — **not run**\n- Outside status: **disabled**\n- Source: **none** (no reviewer, native or external, produced findings in this step)\n- Coverage credit: **none** — this is not a clean review, and per the workflow missing coverage is non-blocking. Approval readiness rests solely on the already-completed native engineering review of PLAN.md (the `--json` flag on the status command, text output preserved by default, both formats tested).\n\n**One thing you should look at:** the review log already contained a *pre-existing* entry I did not write, timestamped `2026-09-29T16:58:52Z` — about a minute before this session — claiming `status: clean, source: codex, outside_status: completed` for this same plan/phase. I have no evidence a Codex pass actually completed (the config is disabled, and `source: \"codex\"` requires completed CLI output per the workflow). I left it untouched rather than delete a record I didn't create, but I'd treat it as unverified and not count it as outside coverage for this plan. If it's a fixture artifact, fine; if not, it's worth finding out where it came from.\n\n**Next step per the workflow:** continue to the remaining planning decisions and Approval readiness.",
