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-build-node's integration tests read the Node toolchain installed only where the node holds node-build-node, and
skipped on ace: its package now declares node-build-node beside its tests; the integration digest names it, a node
lacking it leaves the package unmet for the checker to place, and declines a placed ask. Re-pins mesh-sdk feat/890-placement.

Pins mesh-sdk fix/1921-every-failure-r, whose check ask no longer stops a level at its first failing test step. A captured fixture with a failing test in each of two packages proves the build module's test step names both.

The review found a cut read took an arbitrary 1000 keys, so the newest steps could be missing. A step id is
base-36 milliseconds plus random digits, so its string order is its start order; the newest max(limit*4, 100)
keys are read now, 1000 at most. The toolchains read logs when it drops keys past its cap.
On a steps state of 1164 keys / 20 MB (mesh-build-node: 10034 keys) the read tools listed every key and
then read each value one round trip at a time, filtering by node only after the Get, so they timed out
at 30 s. Now the keys are filtered by the node's prefix before any Get, the values are read 16 at a
time, at most 1000 a call (the answer says it was cut), and one log line gives rows read and time.
build_*_toolchains reads its values the same parallel way. The kind: a read tool that reads a whole
state key by key; every read tool of the three modules is covered.

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.

An indented log line of another running test that held 'panic:' won over the
real timeout panic, since the lines were trimmed before matching. Go prints
the runtime's lines at column 0; a test's log is indented.
mesh-controller's try was worded 'PASS' again because the race detector
reported after the tests passed and the program exited 66. The cause is now
the race: its access, the frame that made it and where its goroutine was
created, instead of PASS or testing's generic 'race detected during execution
of test'. Tests from captured go test -race -json (1901/AC4).
A try of mesh-controller kept 'PASS' as its only failure: the package's test
program stopped after printing PASS and the package-level failure took its
first line. Now a failure that is not one test's assertion names the tests that
were running and carries the panic line (a timeout's with its running tests),
a signal or fatal error line, a build's first error, or words saying the
program exited during which tests or after they passed; go test's summary lines
are never kept. Tests from captured go test -json of eight real failures
(1901/AC4).

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).
mesh-build-go binds /var/lib/mesh-build-node-cache/toolchain read-only into the
integration level's one shut-off process when it is there; the unit level never.
mesh-build-node opens its installed toolchains to other accounts (folders 0755,
files 0644, writable by its owner alone; its cache 0711, so the npm cache beside
them stays its own), and realMachine copies the toolchain of its own lock from
there instead of npm ci from the registry, which the level cannot reach.
The catalogue's paths check (ADR 0260) reads every file of a module but its documentation and tests, and
the verbatim manifest names claude-code's own paths; as a constant in a _test.go file it stays a real
capture without being taken for one module reaching into another's state.
