The review of the reference implementation against moshcode found the two
readers disagreeing on the same files. This round applies the shared
rulings so both sides read a ledger the same way.
Ceiling (R-A, R-B, R-C, R1, R6, R10, R15, R17): memberCeiling rebuilds the
effective ceiling from the ledger on every read. The latest fleet-target
fleet.cap (else fleet.open, else the implicit fleet's) replaces the copy in
a record, so a sysop's widening cap reaches running members; then each
swarm.spawn narrowing down the path, then swarm caps last. In the implicit
fleet a parentless record's own approvals enters at the root; a ceiling a
writer left without the key is never read as native, and startMember fills
it with the engine's word while the record is unclaimed. A fleet.open or
cap with no hosts means the host it was written on (R23).
Once-markers (R-G, R28): member.start, member.end and swarm.end each take
an exclusive create under fleets/<fleet>/marks/<event>.<id> before the
append; a lost end takes <id>.lost so a real end can still supersede it.
The hooks let a real end follow a lost line (R9).
tree (R-F, R20): run by the sysop it enforces rule 6, stopping a member
past its effective until with state timeout and the members of a swarm or
fleet at its budget with state budget, then writes swarm.end for each swarm
touched once it is complete. An agent's tree stops nothing. lost is written
only for a member its engine's roster can hold: a claude-code background job
(8-hex member or session) or a moshcode pane, never an interactive session
claude agents does not list (R-E, R3, R14). A nested swarm is drawn under
the member that spawned it and its row shows the effective ceiling (R25).
stop and cap (R-D, R-H, R22, R27): swarm.end is written only once every
member and every nested swarm has an end line that counts; an engine that
will not end a member leaves it without an end line and the verb exits
non-zero. claude stop takes the job id: the member of a background job,
else the first eight characters of a session UUID; an interactive session
with no job id cannot be stopped and the tool says so. cap on a swarm
refuses a key that would widen. A derived claude-code job is named by its
job id and carries no pid.
Also: R-I (endMember ends only the engine-minted swarm of one), R35 (a
derived record's guessed approvals corrected at UserPromptSubmit), R32
(the UserPromptSubmit hook passes only exit 2 through), R31 (package
README), R36 (rule 13 says the launcher test is unimplemented in 0.1),
docs and PRD 0008 updated for lost, rule 6 and the markers. 113 openfleet
tests, 93 CLI tests, contract green.
