Change A rebuilds the three build modules, so their runtimes restart once; it
changes nothing else about their builds until change B gives them the share.
Review round 1: a cap per module let three build modules take three shares
of the node. The share is now one node value held by the node-engine's
yielding slice; each step divides it by every build slot of the node, from the
composer's words, or assumes every build seat at its own capacity without them.
The operator's desktop slows while it builds (shanks at 92%, the Go build
runtime at 1650% of 24 processors). The build modules declare cpu-cap
(default shanks=50,g14=50,ace=75), which the composer turns into the runtime's
quota at idle priority; each step's go, node and buildah commands get
GOMAXPROCS and UV_THREADPOOL_SIZE for their part of it, and the status tools
show the limits and what the kernel holds the runtime to.
mesh/delivery-group group fix/steps-bucket-ages held: a member is held: novox/mesh-sdk@518dae5ec9c8 (merged without a passing check: only a person decides what…

Without it in Kept, stdio.KeptState refuses the state before the bus (mesh-sdk go/keeps.go
refusedUnannounced), so the pause could be neither read nor written.
mesh-build-go's steps bucket filled to the bus's 64 MiB cap (27,370 keys, none ever removed) and
refused the end of a passed check, so the check read failed; mesh-build-node's (17.8 MB) and
mesh-build-image's grow the same way. A step's key is per step: its reader reads its end within
the step's bound, and a check's verdict is kept by the checker, so two days is ample. The node's
pause key lived in the same bucket and would have ended by itself; it moves to a pauses state
without an age (mesh-sdk fix/steps-bucket-ages, Puller.PausePut). No node is paused today, so
nothing is carried over.
g14's Go builder sat idle at capacity 2 because nothing woke its parked
puller. mesh-build-go, mesh-build-node and mesh-build-image now pin mesh-sdk
b9911dc1, whose puller watches the config value capacity as mesh-config
resolved it and wakes on each change, and hand it that watch.
mesh/delivery covered after its failure: a later walk that contains it was delivered: plan-1792875397682979170 (novox/mesh-catalog at 6fb0ceee into main,…

mesh-build-go, mesh-build-node and mesh-build-image refuse every fetch, test
and build, and say unhealthy, while their work or cache filesystem has less
than 20 GiB free (build-agent's floor), so the builder chooses another node
instead of filling this one. Each serves build_<x>_release, removing a
workspace once its caller's last step answered; a failed fetch removes its
own; a workspace never released goes two hours after its last use (ADR 0509)
in place of a day, never while a step holds it. Pins mesh-sdk's
fix/1839-build-floor (buildstep.Floor, buildstep.Workspaces).
The local narrowing of mesh-build-go and mesh-build-node moves into mesh-sdk (feat/r4e-sdk
d1af87a), with its tests; each module keeps its fetch-level test on real git. The three
build modules are pinned to d1af87a.
Kept (keys, steps, each read by another module today) is said with stdio.Keeps before the
module serves; announcetest.Check holds the announcement equal to the code. Pinned to
mesh-sdk feat/r4e-sdk 9cb4d59. The manifest test's call of the deleted
StateReadsNothingDeclares still has to go (the edit is waiting on the operator's permission).
