Both central nodes ran on the NotificationOutboxOptions code defaults
(100 / 10s = 600/min) because the mounted per-node appsettings.Central.json
had no ScadaLink:NotificationOutbox section. Add the section with
DispatchBatchSize 1000 + DispatchInterval 5s — measured ~6,000/min after
restart (sweep duration becomes the binding constraint, which is fine:
the no-overlap guard self-regulates). Dev-cluster tuning only.
The cookie SecurePolicy was hard-coded to Always, so the auth cookie was always
marked Secure and the browser never sent it over plain HTTP — making login
impossible on the HTTP-only Docker dev cluster (login succeeded server-side but
every following request was unauthenticated). Add SecurityOptions.RequireHttps-
Cookie (default true — production stays HTTPS-only); when false the cookie uses
SameAsRequest. The docker/ central nodes set it false.
Multi-stage Dockerfile with NuGet restore layer caching, per-node appsettings
with Docker hostnames, shared bridge network with infra services, and
build/deploy/teardown scripts. Ports use 90xx block to avoid conflicts.
