A repository never merged through the gate has no entry in source.main, so its pull requests were dropped without a log
line, a verdict or a status, and checker_status counted them as new. Now the verdict says it cannot be judged and why,
the forge status is error with those words, checker_status names it under cannot_be_judged, the log says it once per
head, and the heads are judged whole once the trunk head is known. Quick fix: this. Thorough fix (the gate seeding
source.main from the pull message's base head) is still to do: it needs mesh-sdk, the forge bridge and the gate.
The checker wrote a try's asks only at its end, so a 31-minute try could not be told queued from
running (issue 1890). The try's record now names each ask as it is put, then the node that took
it, its state and the phase its step says, written on the step key's own changes. build_usage
names a running try's asks and takes a build module's capacity.<node> (configured bounded by its
node's build CPU, issue 1806's follow-up) when it is current with mesh-config.
The operator's question (how much are the build nodes used, is ace eligible) took six calls over four tools.
build_usage reads it from the bus's states: seats held (have), capacity (mesh-config resolved), pauses, the
build modules' steps by kind with left-running keys, the last hour and day with total and median time and time
at capacity, the running tries, and the backlog the view program reads from the seats' streams. A try now names
the asks it put, and the checker announces its tries readable, so the view tells a try's asks from a check's.
mesh-controller's try asked build-agent, which leaves the checking at R4e. A try is now a key in the checker's state
tries: the checker judges the head merged onto its trunk as it judges a pull request's head, through the same
judge, places and holds, writes its end in the key and owes the forge nothing (no status, no preview, no verdict).
One try per head, at most four at once; hq and a repository whose trunk the gate does not name are refused with
"no level of <repo> is checked by the checker".
The gate decides on mesh/check alone and matches an Approve's members by the heads hash over lowercase repositories
and heads. A success judged on an old trunk stood on the forge while the next check waited for a place or a delivery,
and a candidate whose repository the forge named in capitals carried a hash the gate never finds. A check that ends
after its trunk moved now owes pending, not its verdict.
