✔ W3: acquire while stopping, uncertain, or stopped without proof refuses unsafe-replacement (472.496544ms)
✔ W4: same session with another seat tuple, and the reverse, both refuse; a loser on the seat key closes it no-unit (268.375073ms)
✔ W4: a hard link of one session under another seat is the same session: the second controller refuses already-active and launches nothing (246.287921ms)
✔ W4: a copy of one session under another seat is the same session: the second controller refuses already-active and launches nothing (275.581255ms)

✔ W5: SIGKILL between every publication barrier of release; restart finishes or holds the release (28721.630848ms)
✔ W6: controller killed mid-turn while the engine lives; restart is uncertain, no launch, prompts refuse (425.153978ms)
✔ W12: a live owner paused with SIGSTOP; a second controller refuses already-active and changes nothing (160.074522ms)
✔ W13: crash after the engine spawns, before active; restart finds the live unit: uncertain, no second spawn, force stop only (440.44504ms)
✔ W14: crash after reservation, before the spawn marker: stopped with a no-unit observation; the pair is free (305.543379ms)
✔ W20: crash after the spawn marker, scope collected; uncertain in both runs, the marker is copied, no launch until a boot proof (404.469792ms)

✔ K3: SIGTERM acknowledged while a member lives: stopping until the kill phase, never stopped from TERM (2757.697662ms)
✔ K4: two engines; force stop one; the other survives by independent observation (5268.048614ms)
✔ K5: a stop during a tool call leaves the effect uncertain, and it is shown (2519.614996ms)
✔ K12: a member forking in a loop: the freeze stops it, enumeration is complete, populated 0 after cgroup.kill (2517.187317ms)
✔ K13: a member writing its pid into another cgroup is refused by the namespace; the kill is complete (2319.730115ms)
✔ K15: the shim gone, engine/cgroup.events unreadable, or the engine cgroup missing: evidence unavailable, not empty; uncertain (4843.065359ms)

✔ K7: recover after proof, then launch: new claim and execution, generation +1, same leaf; the cancelled prompt is not replayed (407.607433ms)
✔ K8: an engine that loads another leaf on resume is refused before admission; it stays claimed until a proven stop (481.50494ms)
✔ K9: an interrupt that never settles stays uncertain; force stop stays available; takeover is refused while fenced (3276.206316ms)
✔ K16: a claim from another machine ID refuses foreign-host; no boot proof is issued (39.317371ms)
✔ K17: two launcher calls with one eligibility record: one launch, the other refuses, no second engine (346.907107ms)
✔ K18: the leaf changes after eligibility: launch refused; the reservation stays until released with proof (330.257916ms)
✖ K19: a scope launched with only the engine environment still reaches the user manager; the engine sees no other names (2.884999ms)
✔ S1: `/goal x`, with leading spaces or a tab, refuses text-policy at admission; zero engine bytes (201.115283ms)
✔ S2: every prefix pinned Pi interprets is refused, from the list the code uses; the rest reach the engine exactly (211.570095ms)
✔ S3: `/goal` on the second line is pinned from the source: Pi checks only index 0, so it is admitted and sent exactly (214.702081ms)
✔ S4: a `/` left in the composer is cleared when control transfers and returns; the next submit sends only the new text (352.014843ms)
✔ S5: an observer terminal gets a paste then Enter, as send-message.sh does: not admitted: controller, nothing sent (194.613313ms)

✔ P3: a Pi confirm, select, input or editor dialog is shown disabled with a reason and never answered (338.928015ms)
✔ E1: send, ack, user, toolCall, toolResult, final answer: shown once, no refresh, draft and reading position kept (278.039565ms)
✔ E2: U+2028, U+2029 inside JSON strings and CRLF line ends each parse as one record, on the splitter and through the controller (210.97132ms)
✔ E3: a multipart final, two blocks, null request correlation and duplicate delivery (219.305896ms)
✔ 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 (214.376273ms)

✔ terminal: Ctrl-T then Enter in one chunk is judged after the takeover, as if typed one key at a time (Filbert F2, #1507) (1.054752ms)
✔ terminal: an action that throws still releases the input held behind it, in order, then rethrows (5.917936ms)
✔ terminal: after an action throws, later input still runs; input() puts the error in the status line (Filbert N1 on #1522) (0.363857ms)
✔ terminal: invisible and bidi characters are made visible; head, status and notice lines stay one line (0.096568ms)

✔ H15: a revoked connection's command is refused; the revocation fence holds (298.547727ms)
✔ H16: a second controller for the same session refuses already-active; the first is untouched (259.606662ms)
✔ H10: a second force stop while the first escalation runs refuses fenced; one escalation, and the claim records only the first stop's phases (1251.319396ms)
✔ a force stop whose fence throws leaves no escalation flag behind, so the next force stop runs (Darkwing F2, #1507) (511.769523ms)
✔ H17: a confirmation reused, answered from another connection, or used after the stop changed is refused (815.430781ms)
✔ H18: two prompts before any native output: the second refuses busy; one engine write (202.535553ms)
✔ H19: the pipe fails mid-line under a large prompt: delivery-unknown transport-unknown, poisoned, no later write (352.883403ms)
✔ H19: the link itself never writes again after an unknown outcome, whoever calls it (0.711028ms)
✔ H19: the controller dies mid-write of a large line: after restart the outcome is unknown and nothing is resent (614.292922ms)
✔ H20: the line is written but the ack is lost when the controller dies: orphan, outcome unknown, nothing resent (558.283096ms)
✔ H21: a retry of the exact request with the old token after a crash is stale-incarnation; no second write (883.075575ms)
✔ H22: after H21 and a valid recovery, a new request with the new token is admitted (2899.722981ms)
✔ H23: requests pending at a restart are not resent; each shows outcome unknown (633.046632ms)

✔ F2: a truncated trailing line marks the view incomplete, not an error (1.183773ms)
✔ pagination: 100 parts, then the rest; parts concatenate to the whole branch (3.200172ms)

✔ the engine pin holds for the installed package (1.628098ms)
✔ pinned Pi, sealed and without credentials, answers the controller's commands with the shapes the fake models (247.561343ms)
✔ sealed, pinned Pi ignores a trusted project's .pi resources; --approve past the seal would load them, and checkSeal refuses it (Filbert F2 on #1522) (538.434901ms)
✔ pinned Pi appends thinking_level_change at start when the branch lacks one, so the leaf moves (K8 then fails closed) (322.058507ms)

✔ N19: a losing extension prompt settles inside the Mosaic run before its user message: O3, run-overlap (555.910759ms)
