The two items deferment.md §0.1 named as the remaining untracked engineering.
adminui-followups (19 pending / 0 completed) — CLOSED by the overlap audit the plan
itself asks for first, with no code written. All 19 tasks are shipped, superseded by
v3, or moot. WS1's premise had also expired: it assumed driver-embedded tag lists in
DriverConfig are the runtime source of truth, which v3 ended (the artifact populates
RawTags). Its capability shipped in the v3 shape — TagConfigEditorMap + DeviceFormMap,
both verified reachable from RawTagModal/DeviceModal rather than merely present.
Live gates on docker-dev (image rebuilt: the rig was running a build 3 h older than the
last code commit; parity asserted per container plus a positive check that the symbols
under test are in the shipped DLLs):
- R2-03 T11 PASSED — build 0 errors, Runtime.Tests 555/555, RoslynVirtualTagEvaluator 20/20.
- R2-03 T12 PASSED — VT 42 -> 0x80020000 -> 42, staged WITHOUT a deployment (a Modbus
register flipped on the fixture) so the VT child survived; a deploy-driven trip creates
a fresh child with no last value, which is correct-by-design and masked the result twice.
P7 confirmed: two byte-identical redeploys, zero disturbance.
- driver-reconfigure Task 3 PASSED — a faulted driver adopted a corrected config and
connected with the node's startedAt unchanged and RestartCount=0.
- R2-10 T10 still OPEN, but the recorded cause was wrong. Not ConnectionBackoff
throttling (the breaker opens on 2 failures / 30 s): the dead-endpoint failure mode
never enters the resilience pipeline. IDriver.InitializeAsync is not invoker-wrapped
(DriverInstanceActor.cs:707) and ModbusDriver swallows per-tag failures in BOTH
directions, so even the plan's fallback trigger cannot work. Live-proven: a driver
timing out every read against a blackhole reported ConsecutiveFailures=0 while the
panel read "All targets healthy."
Finding from T12: the Bad publish's documented "carrying the last-known value" is
unobservable by any client — subscription and a raw Read service call both return NULL.
The actor is correct; every existing failure assertion checked StatusCode alone, so the
value half was asserted nowhere. Adds
VirtualTagActorTests.The_Bad_result_carries_the_last_known_value, which proves the actor
emits it. The documentation is what overstates.
