FNXC:TaskReview 2026-06-28-00:00:
The Address PR feedback affordance must render identically on the task card and Review tab. Gate it on one shared predicate so a linked primary PR with comments or CHANGES_REQUESTED is actionable, while no-PR and no-feedback states render no empty button shell.

FNXC:TaskReview 2026-06-28-16:39:
The button promises an AI session starts, so it must only render for task states the lifecycle route can actually start or wake. Restrict the launch affordance to in-review and in-progress tasks rather than letting terminal/todo cards add steering comments without active work.
