Re-ran every gate docker-dev and the fixtures can run, on master 412da27c plus the
deploy-API fix: A (now with dotnet-counters), B, C, D check 4 (after #785), E, H1
live end-to-end over OPC UA (N=0 year window: 6 pages <= 10k, continuation points,
all 52,560 values), the gate-F removal drop on the VD03 gateway (4 -> 2 within 15 s),
and all fixture lanes incl. the first G1 MTConnect run. All pass.
Recorded: the AbCip "writes" combination ran no writes (AB_DIFF_ENDPOINT gates them
off), a C-style pause past 15 s leaves a split SITE-B pair, and simulator evidence for
four of the five hardware userGates (TwinCAT has no simulator). The hardware
userGates stay open.

PASS: gauge baseline 2, +2 with the rig's driver on both centrals, 4 after 20
config deploys (40 respawns; rig opened 39 / closed 37). Final drop after
removal not observed: the Mac's VPN to VD03 dropped right after the settle.

(a) ScriptRunGuard logs its quarantine Error through the seam's script root
logger, which carries no ScriptName, so ScriptLogCompanionSink mirrored it to
the main log as "[Script] unknown emitted Error ..." and rate-limited every
quarantine on the node under one shared "unknown" key. The guard now binds the
script instance key as ScriptName (ForContext) on the quarantine Error and the
subscriber-threw Warning, so the mirror names the script and limits each one
separately. Test drives two real quarantines through the companion sink with a
1-per-window limiter: both mirrored, each named, none "unknown". Mutation-
checked: dropping the ForContext fails it.
(b) Evaluated a quarantine-specific OPC UA status (BadOutOfService) and kept
BadInternalError: it is the documented code for any script-attributable fault
on virtual tags, Calculation tags and scripted-alarm quality (and the
out-of-process runner design keeps it), BadOutOfService reads as a deliberately
disabled point, a new code is a ScadaBridge-visible contract change, and the
once-per-Good->Bad dedup means a timeout-driven quarantine would rarely show a
different code anyway. Documented in docs/VirtualTags.md ("Quarantine: what a
client sees"), with pointers from Calculation.md, ScriptedAlarms.md and the
OpcUaStatus.BadInternalError doc comment, plus where a quarantine IS visible.

In the normal timeout branch (some acks landed) the deployment row was set to
TimedOut with a null FailureReason, so GET /api/deployments/{id} could not say
which node to fix; only the central log named it. The branch now persists a
reason naming the silent nodes ("Timed out waiting for acks (n/m landed). No ack
from: ..."), bounded to 20 named nodes plus a count of the rest, and still
backstopped by the 2048-char Truncate.
Tests: the reason names the silent node and not the acked one; on a 25-node
silence it names 20, counts 5 and fits the column. Mutation-checked: dropping
the SetFailureReason fails both, dropping the bound fails the second.

The docker-dev centrals logged "Mesh PSK secret ot-mesh-psk-<cluster> ... is
absent (or blank) in the store; the key is REVOKED" for every cluster on every
contact refresh, while every gRPC dispatch and ack authenticated.
Investigated: not an auth bypass. The rig supplies each cluster's key through
MeshTransport:ClusterPsks (central side, equal to that cluster's nodes'
MeshTransport:GrpcPsk) and seeds nothing in the store. TryGetPsk/Matches consult
the override first on every call, so enforcement was on; only RefreshAsync read
the store for those clusters regardless and logged a revocation that never took
effect. RefreshAsync now skips clusters covered by a non-blank override, so the
REVOKED warning is only logged for a cluster that genuinely has no key.
Test pins it with a positive control (a cluster with no override is still read,
warned about and refused) and enforcement on the override key (wrong token
rejected). Mutation-checked: removing the skip fails the test.

Gates A (#731), B (#732), C (#733) and E (#734) run on the local docker-dev
rig against origin/master 1b9c36f3 on 2026-11-09: all four PASS. Records the
procedure, the measured thread/fd/RSS, subscription and deploy-status
numbers per gate, plus six non-blocking observations.
