✔ no shim from this file's tests is left running for the after hook (17.525407ms)
✔ S1: `/goal x`, with leading spaces or a tab, refuses text-policy at admission; zero engine bytes (41.57313ms)
✔ S2: every prefix pinned Pi interprets is refused, from the list the code uses; the rest reach the engine exactly (32.562134ms)
✔ S3: `/goal` on the second line is pinned from the source: Pi checks only index 0, so it is admitted and sent exactly (23.208692ms)

✔ E4: a page read after message_end but before its entry is persisted: marker at the seam, re-read after run-settled, each message once (31.515036ms)
✔ E4: a gap or a new epoch also reconciles; nothing is concatenated across a gap (11.50735ms)

✔ E6: a tool result delayed across a pause and a reconnect is reconciled without a manual refresh (46.087027ms)
✔ E7: the terminal renders the same stream as the library client, as observer and then as controller, and submits only as controller (39.012862ms)

✔ terminal: Ctrl-T then Enter in one chunk is judged after the takeover, as if typed one key at a time (Filbert F2, #1507) (0.570652ms)
✔ terminal: input held behind Ctrl-T waits for that takeover while an earlier action is still pending (Darkwing T1 on #1522) (31.990374ms)
✔ terminal: a hold inside held input holds again, and once it is drained later input and Ctrl-C still reach the terminal (Darkwing note 1 on #1522) (0.646024ms)
✔ terminal: an action that throws still releases the input held behind it, in order, then rethrows (5.066823ms)
✔ terminal: after an action throws, later input still runs; input() puts the error in the status line (Filbert N1 on #1522) (0.883697ms)
✔ terminal: input() reports an error when it happens, so it never overwrites a later status; held input's promise doesn't carry the holder's error (Filbert N4 on #1522) (0.670662ms)
✔ terminal: invisible and bidi characters are made visible; head, status and notice lines stay one line (0.188098ms)

✔ H10: an overlap during the pause before the abort: no abort, the stop ends uncertain (24.487141ms)
✔ H10: a no-turn Interrupt lifts only its own fence; admission stays closed under force stop, overlap or revocation (82.531857ms)
✔ H11: the controller disconnects mid-turn: work continues, the claim is unchanged, control stays put (132.25551ms)
✔ H12: an exact retry after reconnecting to the same incarnation returns the same receipt; one dispatch (20.81694ms)
✔ H13: a retry with the same request ID and different text is refused (23.586558ms)
✔ H14: late stdout from the old engine after a replacement is dropped by incarnation, counted, never rendered (143.137981ms)

✔ H19: the pipe fails mid-line under a large prompt: delivery-unknown transport-unknown, poisoned, no later write (127.571437ms)
✔ H19: the link itself never writes again after an unknown outcome, whoever calls it (0.921566ms)
✔ H19: the controller dies mid-write of a large line: after restart the outcome is unknown and nothing is resent (556.28349ms)
✔ H20: the line is written but the ack is lost when the controller dies: orphan, outcome unknown, nothing resent (397.442413ms)
✔ H21: a retry of the exact request with the old token after a crash is stale-incarnation; no second write (369.017779ms)
✔ H22: after H21 and a valid recovery, a new request with the new token is admitted (2475.767375ms)
✔ H23: requests pending at a restart are not resent; each shows outcome unknown (469.56075ms)
✔ no shim from this file's tests is left running for the after hook (16.798311ms)
