Adds a project-owned, controllable Sparkplug B edge node (SparkplugEdgeNode) that
encodes with the SAME generated Tahu schema the driver decodes with — so the live
gate checks encode/decode symmetry rather than the driver against itself — and
drives the §3.6 matrix end-to-end over the real TLS+auth Mosquitto fixture.
The simulator frames its topics independently of SparkplugTopic.Format: a
simulator borrowing the parser's formatter could not detect a bug in it, because
both sides of the comparison would be wrong together. It registers a real NDEATH
Last Will at CONNECT, restarts seq at 0 on NBIRTH, publishes DATA metrics as
alias-only, carries bdSeq per session, and encodes signed ints as two's
complement in the unsigned proto field.
SparkplugLiveTests (Category=LiveIntegration, env-gated, skip-clean) covers:
birth -> alias-only data -> OnDataChange under the RawPath; late-join rebirth
NCMD honoured by an independent decoder; alias reuse across a rebirth routing by
metric NAME; a stale-bdSeq NDEATH ignored while the current one stales; the real
broker-published Will staling and the next birth restoring; seq wrap 255->0
requesting no rebirth while a deliberate gap does; and the browser's passive
window asserted ON THE WIRE (a third client watching spBv1.0/{group}/NCMD/#),
plus RequestRebirthAsync node-vs-group enumeration.
Two things make the suite falsifiable rather than decorative: the seq-wrap test
builds its ingestor with rebirthDebounce: TimeSpan.Zero (at the shipped 10s
default a wrap-triggered NCMD would be swallowed and the test would pass for the
wrong reason) and pairs the silence with a deliberate gap that must produce one;
and the passivity assertion observes the broker rather than the session's own
publish counter, which can only see the seam it guards.
Docker/docker-compose.yml gains a profile-gated `sparkplug-sim` service running
the same engine standalone against the same broker (TLS, CA-pinned) — a manual
driving aid for the AdminUI picker, deliberately NOT a test dependency, since the
matrix needs an edge node it can command mid-test. Its app directory is publish
output (publish-simulator.sh), gitignored like secrets/.
Offline: 15 skipped, 0 failed with no env set. Live: 15/15 passed against
10.100.0.35:8883. Falsifiability spot-check: mutating AliasTable.RebuildFromBirth
to merge instead of replace, and neutering SparkplugCodec.ReinterpretSigned for
Int32, turned exactly the two corresponding tests red and nothing else; both
mutations reverted.
