coder-mos1 hit 102.5%/372k on RM-03 with 28 modified files uncommitted and its branch
still at base — a full context window spent with nothing durable. Caught by polling seat
state, not by any system signal. Nothing warned anyone: no threshold alert, no
pre-compaction hook.
The founding failure mode of this mission — compaction destroying in-flight work —
nearly hit the mission's own delivery twice in one night. RM-01 survived because it had
committed work when checkpointed; this one had none. Commit-then-rotate works;
rotate-without-commit loses everything.
RM-34: a context threshold is not enough — rotation must force a durable checkpoint and
refuse to rotate a seat with uncommitted work. RM-50: seat context is observable state
and must be monitored; relying on an orchestrator to poll is instructions-not-enforcement
applied to lifecycle. Brief doctrine: commit early, commit WIP.
Adjacent: the diff spans 5 guides and 11 templates against a brief scoped to one script.
Queried, not assumed — but a 28-file diff from a one-script brief is a scope signal
regardless of the answer.
