0042 becomes the operator's own rule and stops there: every merge into the main
branch is notified and approved. Notified means proposed and said out loud, not
performed and mentioned; approved means a person says yes to THAT merge. Who
performs it is not the thing worth constraining, which is what makes an agent
merging its own work unremarkable — the checkpoint already happened.
0043 answers the question it did not: where the ordered list comes from. By hand
today, in substrate.lock, because the first node has no control plane to derive
anything from. Afterwards the control plane derives it from module assignments,
resolved configuration, and what each module declares it needs — ordered by the
dependency graph, which is research 011.
So the record is complete on the consumer side and deliberately silent on the
producer side, and that is a legitimate order to settle them in: the host must
refuse what it does not understand whoever wrote it.
One consequence that only appeared when the question was asked: if the graph
turns out not to determine a total order, that is 011's problem and not the
host's. The host is still handed a list and still applies it as given. Recorded
because it is the seam where a future difficulty would otherwise try to migrate
into tier 0.
Both were marked accepted before they had been read. Approved now, so the field
is true — which it was not when it was written.
§2 said "never merge your own", written for people. Applied to an agent it
produced a contradiction that surfaced immediately: an agent asked to merge
cannot merge, because it authored what it is being asked to merge. So every
merge here was either performed by the thing that wrote it, or not performed.
Rejected the literal reading, because an operator clicking merge dozens of times
without reading is not a checkpoint — it is the SHAPE of one, which is worse,
since the record then claims a review that did not happen. Rejected dropping the
rule, because the failure it prevents is not one an agent is less prone to.
So the rule names what the checkpoint actually is: a person deciding, not a
person clicking. Work may be merged by whoever wrote it once a human has
explicitly approved that merge. What "explicit" excludes is the half that can
rot, so it is enumerated: a standing permission cited forever, an instruction to
do the work read as approval to merge it, silence, and the author's own
judgement that it is ready.
This narrows rather than relaxes. The obligation moves from who performs the
merge to whether a person decided — a higher bar in the case the old wording
permits, where a reviewer merges someone else's work without reading it.
Synced, and verified by reading the rule back out of the live page rather than
by trusting the publish.
