✔ resolveSeat: by name under --repo resolves the repo layout (1.236158ms)
✔ resolveSeat: by path resolves the fleet layout (0.327416ms)
✔ resolveSeat: refusals for missing dir, missing launch.sh, non-executable launch.sh, invalid name, and unknown layout (0.720241ms)
✔ tmuxContext: outside tmux, default socket, custom socket, and exec failure (0.661439ms)
✔ makeRegistration produces a record that validates; each shape violation throws SeatError (0.797975ms)
✔ writeRegistration/readRegistration: round trip, permissions, absence, and malformed records (1.246313ms)
✔ updateTask: changes task, taskSetBy and updatedAt only, and refuses appropriately (1.116987ms)
✔ CLI launch: registers, execs the fake launch script, and passes args through (27.532187ms)
✔ CLI launch: --harness lands in the record (32.857114ms)
✔ CLI launch: the launch script's own exit code passes through (31.387682ms)
✔ CLI launch: relaunching a seat rewrites the one registration record (59.054508ms)
✔ CLI launch: omitting --task records an empty string, not null (30.243268ms)
✔ CLI seat task: updates only the task after a launch, and refuses on an unlaunched seat (85.145837ms)
✔ CLI refusals: no args, unknown flag, missing config, already-registered env, and exec failure (133.457854ms)
✔ samePath: equal paths, symlinked dirs, distinct dirs, and non-strings (0.397508ms)
✔ resolveSetBy: explicit --by wins over the environment; absent or empty environment gives unknown; invalid explicit or environment values refuse with exit 4 (0.572516ms)
✔ validateRegistration/readRegistration: taskSetBy is optional; a record without it (written before #1511) still loads unchanged; an invalid one is refused; the version does not change (0.728897ms)
✔ updateTask: records setBy, preserves startedAt and every unrelated field, upgrades an old record in place only when the task is set, and replaces a previous attribution (0.866342ms)
✔ CLI seat task: --by beats MOSAIC_AGENT_NAME, the environment beats nothing, empty environment is unknown, invalid --by or environment refuses with exit 4 and leaves the record byte for byte (271.441109ms)
✔ family: exactly one launch.max key in the model name, else null (0.663184ms)
✔ sessionEnv passes only the allowlist, the repo's bin on PATH, and the run id (0.653981ms)
✔ newRun: short ids, 0700 directories, and a refusal when the socket path won't fit (1.49126ms)
✔ session file and launch log: 0600, the session file written once (0.962772ms)
✔ endReason maps the runner's exit codes; a signal is killed (0.119269ms)
✔ Registry mirrors to sessions.json; readSessions marks live entries; bad files refuse (1.234913ms)
✔ stopSession refuses an unknown run, reports a stale one, and won't signal a pid that isn't a runner (1.007553ms)
✔ a session runs under unshare as pid 1 of its namespace, claims, answers, and stops on mosaic stop (311.632155ms)
