    Parked at the cop's order (S1 was 5/4): unlinked from S1 #3863, milestone moved 0.71.0 -> 0.71.1, owner a7 kept. P2, no branch, no PR. Re-enters S1 when an S1 child closes. Nothing reads sub-issue membership (no code, workflow or contract).

    Evidence for the fix this issue asks for.

    The cancel-superseded.sh <PR> tool already does every clause: it lists in-flight runs, keeps every run on the PR's current head, cancels only superseded shas, is a dry run unless --yes, re-reads the head before each cancel, and refuses (exit 2) on any failed read. It lives outside this repository, so there is no repo change.

    What was missing was a test. There is now a case table beside the tool. It runs a sandboxed copy of the tool against a stub gh, so it makes no GitHub call and writes no real state.

    Case	rc	Cancelled
    dry run (1 run on head, 2 superseded)	0	none
    --yes	0	only the 2 superseded
    head read fails	2	none
    run list fails	2	none
    head re-read fails before cancel	2	none
    head moves onto a listed run between list and cancel	0	that run kept, the other cancelled
    only current-head runs	0	none
    no in-flight runs	0	none
    non-numeric PR	2	none
    unknown flag	2	none

    Result: 10 ok, 0 broke.

    Mutants (each must turn a row red):

    • M1, the keep-current-head check removed: 9 ok, 1 broke.
    • M2, the re-read-before-cancel check removed: 9 ok, 1 broke.
    • M3, the dry-run default removed: 9 ok, 1 broke.

    Closing is left to the issue's owner.

    Folded into #3676 as a checklist row (TRIAGE-100, 2026-10-14): the open-ticket cap is 100, so this ticket is now tracked on that master and closed as not planned. Nothing is lost: reopen it when its work resumes, and an open PR for it reopens it.
