✔ resolveSeat: by name under --repo resolves the repo layout (1.254502ms)
✔ resolveSeat: by path resolves the fleet layout (0.516747ms)
✔ resolveSeat: refusals for missing dir, missing launch.sh, non-executable launch.sh, invalid name, and unknown layout (0.847962ms)
✔ tmuxContext: outside tmux, default socket, custom socket, and exec failure (0.635368ms)
✔ makeRegistration produces a record that validates; each shape violation throws SeatError (0.803431ms)
✔ writeRegistration/readRegistration: round trip, permissions, absence, and malformed records (1.24324ms)
✔ updateTask: changes task, taskSetBy and updatedAt only, and refuses appropriately (1.239321ms)
✔ CLI launch: registers, execs the fake launch script, and passes args through (30.059497ms)
✔ CLI launch: --harness lands in the record (31.801058ms)
✔ CLI launch: the launch script's own exit code passes through (28.546759ms)
✔ CLI launch: relaunching a seat rewrites the one registration record (58.693016ms)
✔ CLI launch: omitting --task records an empty string, not null (28.874274ms)
✔ CLI seat task: updates only the task after a launch, and refuses on an unlaunched seat (80.75812ms)
✔ CLI refusals: no args, unknown flag, missing config, already-registered env, and exec failure (135.711596ms)
✔ samePath: equal paths, symlinked dirs, distinct dirs, and non-strings (0.40395ms)
✔ resolveSetBy: explicit --by wins over the environment; absent or empty environment gives unknown; invalid explicit or environment values refuse with exit 4 (0.555598ms)
✔ 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 (0.899447ms)
✔ 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 (0.861976ms)
✔ 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 (271.018867ms)
✔ family: exactly one launch.max key in the model name, else null (0.617808ms)
✔ sessionEnv passes only the allowlist, the repo's bin on PATH, and the run id (0.665325ms)
✔ newRun: short ids, 0700 directories, and a refusal when the socket path won't fit (1.463053ms)
✔ session file and launch log: 0600, the session file written once (1.346008ms)
✔ endReason maps the runner's exit codes; a signal is killed (0.107394ms)
✔ Registry mirrors to sessions.json; readSessions marks live entries; bad files refuse (1.244129ms)
✔ stopSession refuses an unknown run, reports a stale one, and won't signal a pid that isn't a runner (1.325051ms)
✔ a session runs under unshare as pid 1 of its namespace, claims, answers, and stops on mosaic stop (260.809593ms)
