Step 2: Wait for review

Sub-agent type: general-purpose; budget: 20-minute hard cap (one bounded sub-agent, NOT extension-driven).

Skipped when the loop is in single-iteration mode — there's no Copilot review to wait for.

Inputs

From step 1:

PrNumber.
baseline — the LatestCopilotReview.submittedAt string captured before the trigger fired (empty string if no prior Copilot review).

02-check-review-status.ps1 JSON snapshot.
recommendation ∈ {ready, give-up-push-commit}.
ready iff both LatestCopilotReview.submittedAt > baseline AND ReviewAtHead: true.

Poll 02-check-review-status.ps1 approximately every 3 minutes until ready or the 20-minute cap is hit:

pwsh ./scripts/02-check-review-status.ps1 -PrNumber <n>

Extract submittedAt and ReviewAtHead from the JSON each tick.
Stop and return ready on the first tick that satisfies both conditions vs. the captured baseline.
On cap reached without ready, return give-up-push-commit.

Don't poll faster than ~3 minutes. There is no progress signal from the API; faster polling only burns budget.
give-up-push-commit fallback is parent-driven. When the sub-agent returns this recommendation, the parent pushes a substantive (non-whitespace) commit — auto-assign on synchronize is the most reliable trigger. Then the parent re-enters the loop at step 1 with a fresh baseline.
Single bounded run, not extension-driven. Do not request extensions on this step — if 20 min isn't enough, the right move is the give-up-push-commit fallback, not more polling.
