Equipment tags were stuck at Bad_WaitingForInitialData on the deployed driver: the equipment poll, fixed-tree loop, probe and recycle shared one FOCAS/2 socket with no serialization, and the steady-state read had no timeout — concurrent reads collided and a stalled read hung forever, never overwriting the node's initial-data seed.
- SynchronizedFocasClient: per-device SemaphoreSlim gate + per-call timeout around every wire op (Connect/Probe gated, not double-bounded); wired in EnsureConnectedAsync. ReadAsync/WriteAsync map a per-call timeout to BadCommunicationError instead of rethrowing.
- FlexibleStringConverter on FOCAS config Series: the AdminUI persists the enum as a number ("series":6); accept number-or-string instead of throwing -> stub.
- FocasHostAddress.TryParse tolerates a scheme-less {ip}[:{port}] (AdminUI hostAddress form); canonical focas:// unchanged, malformed schemes still rejected.
247 FOCAS tests green; each fix has a regression test. Live-validated on wonder-app-vd03 (tags read Good).
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
(99.6%) across three /fixdocs passes.
Driver.FOCAS-001: FocasDriverConfigDto exposed no FixedTree / AlarmProjection /
HandleRecycle sections, so a deployment that opted into those features per
docs/drivers/FOCAS.md had the sections silently dropped by case-insensitive
JSON parsing and the features stayed at their disabled defaults. Added
FocasFixedTreeDto / FocasAlarmProjectionDto / FocasHandleRecycleDto and Build*
mappers in CreateInstance that populate the matching FocasDriverOptions
properties; a missing section or field keeps its existing default.
Driver.FOCAS-002: the fixed-tree bootstrap probe classified ProgramInfo as
"supported" whenever GetProgramInfoAsync returned non-null, but WireFocasClient
.GetProgramInfoAsync substituted defaults instead of throwing on a FOCAS error
return, so a CNC series answering EW_FUNC/EW_NOOPT for cnc_exeprgname2 /
cnc_rdopmode still got the Program/ and OperationMode/ subtrees. The method now
throws InvalidOperationException when neither the program-name nor the op-mode
read is IsOk, so SafeTryProbe correctly suppresses the capability.
Added FocasFactoryConfigTests covering the three opt-in config sections
round-tripping through CreateInstance and the fixed-tree bootstrap classifying
ProgramInfo as unsupported when the probe throws. Added an internal
FocasDriver.Options test seam.
