The Phase 2 soak's "LocalDb fails under load" blocker is NOT a product defect.
Root cause: host-side (macOS) sqlite3 reads of the live, bind-mounted WAL
databases. POSIX advisory locks do not propagate across the virtiofs boundary,
so the host reader believes it is the only connection, checkpoints on close and
resets the WAL to 0 bytes under the container. The container's still-mapped
WAL index then references frames that no longer exist and every subsequent
statement fails SQLITE_IOERR_SHORT_READ (522) -> primary code 10, permanently
until the process reopens the database.
Reproduced on demand both on the rig (one sqlite3 SELECT reset a 4.6 MiB WAL and
produced the first error one second later) and in a minimal python:3.12-alpine
repro with no LocalDb or .NET involved. Refuted the converse: a freshly-reopened
node sustained the full soak load 10+ minutes with zero errors.
The original brief's isolation was confounded - both nodes had been poisoned by
the same sampling pass, and a poisoned standby looks healthy only because it
issues almost no statements. Corrections annotated in place.
Hardening shipped alongside:
- SqliteErrorCodes.Describe: log SQLite primary AND extended codes at the
LocalDb-adjacent catch sites (the missing extended code is what made the
original diagnosis so slow).
- SiteAuditTelemetryActor: stop touching ActorContext across an await
(NotSupportedException), with regression coverage.
- infra/reseed.sh: apply the MSSQL init scripts explicitly. The official
mssql/server image does not implement /docker-entrypoint-initdb.d, so a fresh
volume hung the reseed forever; compose mounts annotated as informational.
Deliberately NOT done: detect-and-reopen self-heal in SqliteLocalDb. It defends
only against external interference, which is now prevented at the source, and
same-kernel production readers see the locks correctly.
Build 0 warnings; SiteAuditTelemetryActorTests 9/9, SiteEventLogging 70/70.

ASP.NET Data Protection ciphertext is non-deterministic and bound to the
source key ring, so encrypted secret columns (ExternalSystemDefinitions
.AuthConfiguration, SmtpConfigurations.Credentials, DatabaseConnection
Definitions.ConnectionString) cannot be replayed from a static SQL dump —
the app would fail to decrypt them. dump_seed.py now emits those columns
as NULL; reseed.sh adds a post-seed stage that recreates the values
through the ScadaLink CLI so the EF value converter re-encrypts against
the target cluster's key ring.
The Test Run sandbox and Monaco analysis modelled a script API that had
drifted from the site runtime's ScriptGlobals, so real scripts failed to
compile in Test Run. Realign both to the runtime surface
(Instance/Scripts/ExternalSystem/Attributes/Children/Parent) and drop the
duplicate ScriptHost stub so the two cannot diverge again.
- Script calls (Scripts.CallShared, Instance.CallScript, Route.To().Call)
accept an anonymous object instead of a hand-built dictionary, via a
shared ScriptArgs normalizer; existing dictionary calls still compile.
- Test Run can optionally bind to a deployed instance, so Instance/
Attributes/CallScript route to it cross-site; adds site-side
RouteToGetAttributes/RouteToSetAttributes handlers.
- Adds Test Run panels to the API method and template script editors.
- Fixes the TestDatabaseQuery seed script, which queried a table that
never existed.
Also commits unrelated in-progress work already in the tree: the health
monitoring report loop, site streaming changes, and the Admin/Design
data-connection and SMTP page reorganization.
