✔ K5: a stop during a tool call leaves the effect uncertain, and it is shown (2573.562278ms)

✔ K16: a claim from another machine ID refuses foreign-host; no boot proof is issued (41.075074ms)
✔ K17: two launcher calls with one eligibility record: one launch, the other refuses, no second engine (324.22541ms)
✔ K18: the leaf changes after eligibility: launch refused; the reservation stays until released with proof (343.053381ms)
✔ K19: a scope launched with only the engine environment still reaches the user manager; the engine sees no other names (81.642916ms)
✔ S1: `/goal x`, with leading spaces or a tab, refuses text-policy at admission; zero engine bytes (204.554136ms)
✔ S2: every prefix pinned Pi interprets is refused, from the list the code uses; the rest reach the engine exactly (199.696713ms)
✔ S3: `/goal` on the second line is pinned from the source: Pi checks only index 0, so it is admitted and sent exactly (296.202561ms)
✔ S4: a `/` left in the composer is cleared when control transfers and returns; the next submit sends only the new text (373.234755ms)
✔ S5: an observer terminal gets a paste then Enter, as send-message.sh does: not admitted: controller, nothing sent (252.69287ms)
✔ S6: a mediated-shaped registration (no tmux) passed to the board's replyToRow: 409 no tmux session; exec never runs (0.467903ms)

✔ P3: a Pi confirm, select, input or editor dialog is shown disabled with a reason and never answered (317.483573ms)
✔ E1: send, ack, user, toolCall, toolResult, final answer: shown once, no refresh, draft and reading position kept (222.941472ms)
✔ E2: U+2028, U+2029 inside JSON strings and CRLF line ends each parse as one record, on the splitter and through the controller (210.138251ms)
✔ E3: a multipart final, two blocks, null request correlation and duplicate delivery (214.663169ms)
✔ 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 (238.356521ms)
✔ E4: a gap or a new epoch also reconciles; nothing is concatenated across a gap (10.98768ms)

✔ E6: a tool result delayed across a pause and a reconnect is reconciled without a manual refresh (251.865348ms)
✔ E7: the terminal renders the same stream as the library client, as observer and then as controller, and submits only as controller (258.085991ms)

✔ terminal: Ctrl-T then Enter in one chunk is judged after the takeover, as if typed one key at a time (Filbert F2, #1507) (0.470947ms)
✔ terminal: input held behind Ctrl-T waits for that takeover while an earlier action is still pending (Darkwing T1 on #1522) (31.503922ms)
✔ terminal: an action that throws still releases the input held behind it, in order, then rethrows (5.802151ms)
✔ terminal: after an action throws, later input still runs; input() puts the error in the status line (Filbert N1 on #1522) (0.39944ms)
✔ 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) (0.384215ms)
✔ terminal: invisible and bidi characters are made visible; head, status and notice lines stay one line (0.119746ms)

✔ H4: self-takeover is refused (212.651704ms)
✔ H9: Interrupt racing a prompt's dispatch: before the write, dispatch-refused and no-turn; after, §3 rules (459.24516ms)
✔ H10: Interrupt and force stop together: one stop chain, force stop supersedes (1245.171331ms)
✔ H10: an overlap during the pause before the abort: no abort, the stop ends uncertain (211.079317ms)
✔ H10: a no-turn Interrupt lifts only its own fence; admission stays closed under force stop, overlap or revocation (566.654958ms)
✔ H11: the controller disconnects mid-turn: work continues, the claim is unchanged, control stays put (291.178611ms)
✔ H12: an exact retry after reconnecting to the same incarnation returns the same receipt; one dispatch (181.967842ms)
✔ H13: a retry with the same request ID and different text is refused (188.861053ms)
✔ H14: late stdout from the old engine after a replacement is dropped by incarnation, counted, never rendered (549.356516ms)
✔ H15: a revoked connection's command is refused; the revocation fence holds (287.426249ms)
✔ H16: a second controller for the same session refuses already-active; the first is untouched (200.444487ms)
✔ H10: a second force stop while the first escalation runs refuses fenced; one escalation, and the claim records only the first stop's phases (857.504193ms)
✔ a force stop whose fence throws leaves no escalation flag behind, so the next force stop runs (Darkwing F2, #1507) (373.700939ms)
✔ H17: a confirmation reused, answered from another connection, or used after the stop changed is refused (887.924023ms)
✔ H18: two prompts before any native output: the second refuses busy; one engine write (237.241452ms)
✔ H19: the pipe fails mid-line under a large prompt: delivery-unknown transport-unknown, poisoned, no later write (478.20367ms)
✔ H19: the link itself never writes again after an unknown outcome, whoever calls it (0.624939ms)
✔ H19: the controller dies mid-write of a large line: after restart the outcome is unknown and nothing is resent (686.653321ms)
✔ H20: the line is written but the ack is lost when the controller dies: orphan, outcome unknown, nothing resent (532.060281ms)
✔ H21: a retry of the exact request with the old token after a crash is stale-incarnation; no second write (775.209066ms)
✔ H22: after H21 and a valid recovery, a new request with the new token is admitted (2925.165901ms)
✔ H23: requests pending at a restart are not resent; each shows outcome unknown (562.491533ms)
✔ a plain conversation: catalogue row, one page, CHAT-01 records (6.270405ms)
✔ native entries map to blocks: tools, thinking, bash, notices, ids that do not fit (1.609092ms)
✔ F1: a malformed line is an unavailable part at its position, and reading continues (1.753356ms)
✔ F1: a missing parent stops the history with a notice that names the unreadable lines (2.527188ms)
✔ F1: an unreadable fork is never merged into another branch's history (1.431048ms)
✔ F1: a follow stays on its branch when the next entry's parent is unreadable (2.071325ms)
✔ F1: a file whose entries are all unreadable shows a notice per line (0.827319ms)
✔ F2: a truncated trailing line marks the view incomplete, not an error (1.305484ms)
✔ pagination: 100 parts, then the rest; parts concatenate to the whole branch (3.904469ms)
✔ F3: a replaced file (new inode) refuses old cursors with reconcile (5.838439ms)
✔ F4: a same-inode rewrite of the prefix refuses old cursors with reconcile (7.06037ms)
✔ F5: growth between pages keeps the epoch and the page stops at the pinned length (6.251335ms)

✔ every page and cursor is a valid CHAT-01 record (793.400268ms)
✔ the engine pin holds for the installed package (1.831292ms)
✔ pinned Pi, sealed and without credentials, answers the controller's commands with the shapes the fake models (271.760635ms)
✔ 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) (542.750506ms)
✔ pinned Pi appends thinking_level_change at start when the branch lacks one, so the leaf moves (K8 then fails closed) (252.66582ms)
