I-1 - a non-C# paste produced thousands of Roslyn markers. The Problems-list report sent
them all as one JS->.NET message, which could exceed the 1 MB hub limit and kill the
circuit. The JS now sends at most MaxReportedMarkers (200) markers, errors first, each
message cut to 300 chars, plus the total. ScriptProblemReport.FromEditor clamps again
on arrival, and the Problems list shows "showing N of Total" / "+N more". The diagnostics
endpoint also bounds its response: Distinct, errors first, MaxDiagnosticMarkers (1000),
messages cut to 1000 chars. An error is always kept, so editor-accepts == publish-accepts.
M-1 - drop the per-instance compilation lineage; analyses derive from BaseCompilation.
M-2 - the VirtualTag modal clears its problems (and editor ref) on close and on a script
reload.
M-5 - an over-limit text is announced at blur (OnSyncRefused), not only at Save.

R04:P1 - the editor no longer ships its full text JS->.NET on every keystroke. It reports
at blur, and ScriptEdit / the VirtualTag modal read the authoritative value with
MonacoEditor.GetValueAsync at Save (validation runs after the pull). The Blazor hub's
MaximumReceiveMessageSize is raised from 32 KB to 1 MB. The JS refuses a value that
would not fit instead of sending an oversize frame, and Save surfaces that refusal
rather than persisting stale source.
R04:P9 - diagnostics carry a generation counter and an AbortController. Every edit aborts
the in-flight request, and only the response for the current text is applied.
R04:S2 - the always-empty inlay-hints provider, endpoint, service method and contracts
are removed.
R04:S3 - MarkersChanged is typed (DiagnosticMarker) and feeds a new ScriptProblemsList.
Clicking a problem calls RevealLineAsync. Markers cross to .NET only when a list
subscribes.

R04:P2 - every analysis derives from one process-wide bound base compilation via
ReplaceSyntaxTree (the scoped service keeps its current compilation); every entry point
takes the request token, the endpoints bind RequestAborted and answer 499 on abort, and
the Monaco providers abort their fetch when Monaco cancels the request.
R04:P3 - the catalog snapshot carries a sorted, de-duplicated string[] (binary-search
prefix completion) and an Ordinal path->info dictionary, built once per snapshot.
R04:S1 - Diagnose emits an OTSCRIPT_SETVTAG_INERT warning for each ctx.SetVirtualTag
call. It is a warning, so editor-accepts == publish-accepts still holds.

ScriptContext.CancellationToken is backed by an AsyncLocal that
ScriptEvaluator.RunAsync scopes around the compiled delegate, so it is
exactly the token ScriptRunGuard cancels on timeout. A polling script
can now end its own abandoned run and free the slot. AsyncLocal rather
than a field because the scripted-alarm engine reuses one context per
alarm: an orphan keeps seeing its own cancelled token. The scoping
entry point is internal (IVT to Core.Scripting) so a script cannot
replace its own token.
Editor parity: ScriptAnalysisService dot-completion now walks the
receiver's base chain (instance members only, stopping before
System.Object). Before this, a member declared only on ScriptContext
compiled and published but never completed. DiagnoseTests pins the
member as allow-listed; CompletionTests pins the completion.

R05:10 — the namespace deny-list covered System.Threading.Tasks but not
System.Threading, so SemaphoreSlim / Monitor / SpinWait / Mutex /
EventWaitHandle could park a script's pool thread past its budget (or touch a
system-global kernel object); System.Type.GetType(string) / GetMethod* /
InvokeMember and System.Runtime.CompilerServices.RuntimeHelpers resolved and
reach a forbidden type without naming it syntactically.
ForbiddenTypeAnalyzer now denies the whole System.Threading namespace with a
type-granular allow-list (CancellationToken, Interlocked, Volatile — the
sync-free primitives), adds a member deny-list for System.Type's reflection
entry points (GetType/GetMethod(s)/InvokeMember/GetProperty(ies)/GetField(s)/
GetMember(s)/GetConstructor(s)/GetEvent(s)/GetDefaultMembers; instance
object.GetType() stays allowed) and puts RuntimeHelpers on the type deny-list.
Thread/ThreadPool/Timer leave the type list — the prefix rule reaches them.
R05:11 — the allocation budget landed with E1's ScriptRunGuard
(Scripting:MaxAllocBytesPerRun, default 64 MB): sampled around each run,
breach quarantines. It is observation after the fact; a pre-emptive OOM guard
still needs an out-of-process runner (follow-up issue in the lane report).
The Monaco editor shares the analyzer, so DiagnoseTests pins every new form
as an OTSCRIPT_FORBIDDEN marker and every allow-listed form as clean.

The issue reports a missing feature. The cause is a stale projection, and the
consequence was worse than the gap described.
`ScriptTagCatalog` still emitted `Tag.TagConfig.FullName` — the pre-v3 driver wire
address. Since v3 the mux key is the **RawPath**: `AddressSpaceComposer` harvests the
`ctx.GetTag("…")` literals into `DependencyRefs`, those become `VirtualTagActor`
dependency refs registered with `DependencyMuxActor`, whose `_byRef` is keyed Ordinal
by `AttributeValuePublished.FullReference` — and a driver's wire ref IS the RawPath
(`DriverHostActor._nodeIdByDriverRef` is keyed `(DriverInstanceId, RawPath)`). The
`{{equip}}/<RefName>` form already substitutes to RawPaths at both compose seams.
So the catalog was wrong in BOTH directions, not merely incomplete: completion
offered paths that could never resolve at runtime, while a CORRECT absolute RawPath
got no completion and hovered as "not a known configured tag path". The file's own
comment admitted the raw/UNS catalog was left for "Batch 2/3" and it never came.
Now projected through the shared `RawPathResolver` — the same byte-parity authority
`DraftValidator` and `AddressSpaceComposer` use — so a suggested path is identical to
the one the deploy gate and the runtime compute. A tag with a broken ancestry chain
resolves to null and is omitted: the runtime could not route it either, so offering
it would be a lie. Hover additionally gains the owning `DriverInstanceId`, which the
topology now makes available (it was always null before).
Editor-accepts <=> publish-accepts is preserved: no diagnostic keys off this catalog
(`OTSCRIPT_EQUIPREF` only marks `{{equip}}` paths), so this changes completion and
hover only — it cannot newly reject a script.
The existing tests pinned the v2 contract and were re-authored: a RawPath only exists
if the RawFolder -> DriverInstance -> Device -> TagGroup -> Tag chain does, so the
seed now builds one. Added coverage for group-nested paths, a driver at the cluster
root (no folder segment), a broken chain being omitted rather than guessed, and the
pre-v3 FullName no longer resolving.
Live-gated on docker-dev (rig rebuilt, both central nodes):
- completion, empty literal -> every RawPath incl. group-nested
`opcua1/plc/OpcPlc/Telemetry/Basic/AlternatingBoolean`
- completion, prefix `pymod` -> `pymodbus/plc/HR200X`, `pymodbus/plc/ImportedTag`
- hover `pymodbus/plc/HR200X` -> "Tag · Type UInt16 · Driver MAIN-modbus"
- hover an unknown path -> "Not a known configured tag path"
AdminUI 742/742; script-analysis 55/55; solution builds 0 errors.
Replace "SystemPlatform mirror tag", "Galaxy alias", and "SystemPlatform-kind" in doc-comments and
test names with neutral accurate wording ("FolderPath-scoped tag", "EquipmentId == null", etc.).
No code, logic, or test bodies changed — comments and one test method name only.
