Extend CommunicationOptionsValidator with eager bounds for the four T4
live-alarm-cache options (linger >= 0, reconcile > 0, seed concurrency 1..64,
subscribers-per-site >= 1). Enforce the per-site viewer cap fail-safe in
SiteAlarmLiveCacheService.Subscribe (reject excess viewers with a no-op
disposable rather than growing the list or throwing into the Blazor render
path). Surface two telemetry instruments on the existing ScadaBridgeTelemetry
meter: an active-aggregator observable gauge and a reconnect counter, wired from
the aggregator actor's PreStart/PostStop and its NodeA<->NodeB flip /
reconcile-driven reopen.

Add FoldHourlyRollupsAsync (in-memory grouped, per-metric gauge-last/rate-sum,
idempotent upsert on the series+hour key with null-ScopeKey equality, exclusive
upper hour bound so the in-progress hour is never folded), GetHourlySeriesAsync
(same KpiSeriesPoint contract as GetRawSeriesAsync), and PurgeRollupsOlderThanAsync
(one-hour-sliced batched DELETE mirroring PurgeOlderThanAsync). Adds 7 repo tests.

New KpiRollupHourly entity is the hourly pre-aggregated series backbone folded
from raw KpiSample rows, letting long-range (30d/90d) trend reads scan ~60x fewer
rows. Same (Source, Metric, Scope, ScopeKey) series key as KpiSample plus
HourStartUtc bucket, folded Value, and MinValue/MaxValue/SampleCount fidelity
columns. UNIQUE IX_KpiRollupHourly_Series (upsert key + range-read cover, with the
default [ScopeKey] IS NOT NULL filter suppressed so Global rows participate) and
IX_KpiRollupHourly_Hour for purge. Non-partitioned, [PRIMARY], no DB-role restriction.

Closes the operator parity gap the deferred-work register tracked as #12: native
alarm source overrides could only be set one-at-a-time, while attribute overrides
had a CSV bulk path. Adds an all-or-nothing CSV import for native sources.
- Commons: extract the RFC-4180 line splitter into a shared CsvLineSplitter
(refactor OverrideCsvParser onto it — no behavior change, pinned by its tests);
new NativeAlarmSourceOverrideCsvParser (header SourceName,Connection,
SourceReference,Filter; blank = inherited).
- Commons: NativeAlarmSourceOverrideEntry + bulk SetInstanceNativeAlarmSource-
OverridesCommand (auto-registered via the reflection command registry).
- ManagementService: Deployer-gated handler — flattens once, validates every
source resolves + is unlocked + no duplicates up front, then upserts the whole
batch under a single SaveChanges (true all-or-nothing txn). Added to the frozen
authorization matrix; dispatch-coverage guard passes.
- CLI: `instance native-alarm-source import --instance-id --file` (parity with
`instance import-overrides`) + README.
- Tests: native parser (Commons), CLI parse/entry mapping, 3 bulk-handler tests
(happy path single-commit, locked-source reject, unresolved-source reject).
Also corrects a stale XML-doc line in ScriptRuntimeContext (WaitForAttribute
quality-gated mode is shipped, not "planned") and updates the deferred-work
register: marks #7/#13/#15/#16/#20 verified-resolved, #12 as CLI/API-shipped with
only the Central UI upload affordance still pending.

Additive UpdateSmtpConfigCommand params (OAuth2Authority/OAuth2Scope),
preserve-on-null handler application, CLI --oauth2-authority/--oauth2-scope
on smtp update, Central UI text inputs shown only for the OAuth2 auth type,
and the Component-NotificationService doc paragraph with M365 defaults.

#05-T19. Import name-resolution findings are now split by origin: template-script
(and attribute-default-expression) references become non-blocking advisory
warnings (ConflictKind.Warning + ImportResult.Warnings) since the design-time
deploy gate re-validates authoritatively; ApiMethod-script references stay hard
errors (SemanticValidationException / ConflictKind.Blocker) as they have no
downstream gate. Names declared locally in a body (Roslyn-parsed local functions
/ methods) are excluded so a script's own helper isn't flagged; KnownNonReferenceNames
extended with common BCL/LINQ/SQL surface. DetectBlockersAsync and
RunSemanticValidationAsync Pass 1 apply the identical split so preview and apply
agree. Rollback/hard-fail tests retargeted to ApiMethods (the still-hard-failing
vehicle). CentralUI preview renders the new Warning badge/advisory.

New Commons seam: ScriptArtifactsChanged record + ScriptArtifactKinds + the
IScriptArtifactChangeBus pub/sub interface. Host ships InProcessScriptArtifactChangeBus
(lock-free copy-on-write, swallow-and-log per subscriber) registered as a central-role
singleton. BundleImporter gains an optional IScriptArtifactChangeBus? and, AFTER
tx.CommitAsync, publishes one notification per script-bearing kind (ApiMethod/
SharedScript/Template) whose resolution was Overwrite/Rename, using post-resolution
names — fully guarded so a bad subscriber can't fail a committed import. Contract +
plan-06 handoff table documented. No consumer yet (additive; publisher is correct).

Add IsLocked to ResolvedNativeAlarmSource; FlatteningService skips overrides on a
locked source (mirrors attribute/alarm lock rules); ManagementActor SetInstanceNativeAlarmSourceOverride
flattens the instance and rejects an override on a locked source (and rejects a
canonical name that does not resolve, preventing dangling overrides).

When a pulled AuditEvent fails to insert on every retry up to the permanent-
abandon threshold, the reconciliation actor now writes ONE synthetic
ReconciliationAbandoned row (new AuditKind) alongside the Critical log line —
fresh EventId, Status=Failed, channel preserved from the lost row, Extra carrying
the abandoned EventId + source site + final error — via the same
ScadaBridgeAuditEventFactory the ingest path uses. Best-effort in its own
try/catch so it never blocks the cursor twice. The permanent loss is now
queryable in the Audit Log, not only in a rotating log file.
Site side: additive proto after_id field, ReadChangedSinceAsync gains an optional
afterId cursor and deterministic (UpdatedAtUtc, TrackedOperationId) ordering — a
batch fully inside one UpdatedAtUtc instant no longer re-reads the same page
forever. Absent/empty afterId preserves the exact legacy inclusive >= contract, so
an older central is unaffected. Regenerated the checked-in gRPC C#.
Additive RequestedBy on Retry/DiscardSiteCallRequest, plumbed from the Central UI.
On an Applied relay, SiteCallAuditActor emits one best-effort CachedResolve central
direct-write row (Submitted/Discarded) with the operator as Actor. Gated on an
injected ICentralAuditWriter (null in existing tests → no mirror read, unchanged);
the site remains the source of truth for the state change.
Additive RequestedBy on Retry/DiscardNotificationRequest, plumbed from the Central
UI. RetryAsync emits a NotifyDeliver Submitted row (records who un-parked); Discard
stamps the operator on the Terminal row. Best-effort — audit failure never aborts
the action.
Retention purge deletes Forwarded/Reconciled rows older than the cutoff and
reclaims pages via incremental_vacuum; Pending rows are never purged on age
alone (would lose audit data that never reached central). Temp-table purge set
avoids the SQLite 999-param limit; runs under _writeLock. (PLAN-04 Task 1, S1/U2)
Remove project bookkeeping citations from shipped code comments across the
solution: hyphenated task IDs (WP-14, StoreAndForward-025), milestone/task/
issue refs (M3, Task 4, Audit Log #23, #21), Bundle X task-bundle labels,
and C/D/K/S/T phase labels.
Comment text only — no code logic, string/log literals, or XML-doc structure
changed. Genuine descriptions are preserved (only the citation is stripped),
and technical lookalikes are retained (UTF-8, SHA-256, T00:00:00, M365,
UTC-5, pre-C4/pre-C5 schema versions). Flagged by the new CommentChecker
TaskReferenceInComment / TrackingReferenceInComment checks plus targeted
grep passes; full solution builds clean, append-only guard tests pass.
