feat(scripting): out-of-process pre-emptible script runner behind Scripting:Runner (lmxopcua#780 P1)
...
v2-ci / unit-tests (push) Waiting to run
Opt-in (Scripting:Runner=OutOfProcess; InProcess stays the default and its code path is unchanged). Implements
the P1 slice of docs/plans/2026-11-09-out-of-process-script-runner-design.md with the owner's §14 decisions:
- Options: Scripting:Runner (InProcess | Shadow | OutOfProcess), Scripting:Runner:Seams, Scripting:Worker:*
(Shards 2, HardGrace max(1 s,T), HeapLimitBytes 512 MiB, QuarantineAfterKills 2, UnavailableGrace 5 s,
IsolationProbationRuns 20, PeCacheDir validated absolute + outside the content root (fail closed),
ExecutablePath). Shadow is not implemented yet: runs InProcess with a startup Warning.
- Core.Scripting: IScriptRunner seam + InProcessScriptRunner (today's guard, the parity baseline).
- Core.Scripting.Protocol: protobuf envelopes, 4-byte LE framing (zero/oversize/truncated/garbage refused),
Variant carrying the exact CLR type; unsupported types are explicit failures.
- ScriptWorker app: compiles in the worker, P-thread scheduler, host-driven soft cancel, fail-fast
watchdog, heartbeats, ctx.Logger forwarding, exits on pipe EOF / parent gone, forbidden-assembly
self-check; Akka and Grpc.Core.Api excluded from its folder. Shipped in script-worker/ (Build + Publish).
- Core.Scripting.OutOfProcess: K shards + isolation worker, soft T / hard T+G kill, attribution
(deadline kill = one key; crash = suspects -> isolation; isolation crash = strike), kill-strike
quarantine, backoff 250 ms -> 30 s, fail closed, cleared allow-listed env, nonce + pid handshake on a
current-user pipe, Windows Job Object.
- VirtualTag + Calculation seams use the runner when selected; a runner-side failure (worker restarted /
runner unavailable) publishes BadResourceUnavailable (0x80040000) — ScadaBridge#112. Script faults keep
BadInternalError. The scripted-alarm seam stays in process (alarms last).
Tests: new ZB.MOM.WW.OtOpcUa.ScriptWorker.Tests (Category=ScriptWorker, real processes; green on macOS and
on windev/Windows), seam tests in Host/Runtime/Calculation suites; mutation-checked.

test(scripting): pin the Scripting section bind behind one helper
...
Review m-1. The bind moves from Program.cs into
Host.Configuration.ScriptingOptionsBinding.Bind, which binds the
section and clamps it. Program.cs calls it, and
ScriptingOptionsBindingTests drives it with in-memory configuration.
Every documented key takes a non-default value, so a misspelled
property or key goes red instead of silently falling back to the
defaults. The tests also cover a clamped bind (1e300 / 1024 / 0, three
adjustments), an absent section, and the sibling LogFilePath /
LogTopicMinLevel keys leaving the bind untouched.
