Each site card carries an Artifacts badge (current / out of date / never
deployed) plus an "N of M instances out of date" line linking to Topology,
both read from the shared pending-updates snapshot. The snapshot loads after
the site list so a slow fleet evaluation never holds the cards, and a failure
degrades the badge to "unavailable" instead of taking the page down. Header
gains a Re-check button and an as-of caption; a successful Deploy Artifacts
forces a refresh so the badge flips immediately.

Tallying filtered the whole deployed-instance set inside the site loop, making the
aggregate O(sites x instances) — the one per-entity loop in an otherwise batched
pass. Group once into a lookup and index per site. Also: ResolveArtifactState's
missing-hash branch is a defensive default, not the race the comment described
(the same site list feeds the hash computation), and the staleness batch omits an
instance undeployed mid-batch as well as one that never had a snapshot.

Both repositories are scoped over one DbContext, so a failed stamp save left the
Site entries tracked as Modified and the deployment record's (uncaught)
SaveChangesAsync rethrew it — losing the audit row and failing a deploy in which
every site succeeded. Ordering rule now: audit row first, stamp after, inside its
own try/catch. Same in RetryForSiteAsync, where the site load is caught too so
nothing on the stamp path can reach the method's catch.
Also: the method-definitions canonicaliser matches the name property
case-insensitively (a naming-policy change at the producer would otherwise
silently turn the sort into a no-op), and ComputeCurrentArtifactHashesAsync
documents that a per-site query failure aborts the whole batch by design.

One scoped read that answers "is anything waiting to be deployed?" for the whole
fleet: each site's stored artifact revision hash compared against what a deploy
would send right now (NeverDeployed / Current / OutOfDate), plus per-site
deployed/stale/unknown instance tallies from the batched staleness evaluation.
NeverDeployed is deliberately NOT a pending update — the operator has not deployed
yet — and exceptions propagate so the caller's single-flight cache can render
"unavailable" rather than invent an "up to date". Adds the validated
PendingUpdatesCacheTtl (60 s) that TTL will key off.

ArtifactRevisionHashService (deterministic SHA-256 of the per-site
DeployArtifactsCommand, DeploymentId/timestamp excluded) stamps
Site.ArtifactRevisionHash/ArtifactsDeployedAt for every site whose deploy
succeeded; failed sites keep their previous stamp.
ComputeCurrentArtifactHashesAsync answers "what would it be now".

DeploymentService.GetInstanceStalenessAsync shares a FlattenSession across
the batch, reads only the (InstanceId, RevisionHash) projection and pays the
snapshot read + I-1 List normalisation only for a mismatch, so the fleet
aggregate agrees exactly with the per-instance Topology badge. The I-1 logic
is extracted from GetDeploymentComparisonAsync unchanged.
Claude-Session: https://claude.ai/code/session_01Y5ef34iUUMjmwnMpL9xgmB
Site.ArtifactRevisionHash / ArtifactsDeployedAt (nullable, migration
AddSiteArtifactRevision) so the Sites page can tell whether a site's
system-wide artifacts are current. Not transported. Adds the
GetDeployedRevisionHashesAsync projection for the fleet-wide staleness batch.

The Flow Debugger link sat as a lone top-level item after the Deployment
section because its policy (RequireFlowDebugger: Deployer + Administrator +
Viewer) is wider than the section's RequireDeployment (Deployer only), so it
did not expand/collapse with the group. The section is now gated on
RequireFlowDebugger — a superset of RequireDeployment — with the three
Deployer-only pages gated per item inside it, so every Deployer sees the
same section as before and a Viewer/Administrator without Deployer gets a
Deployment section holding only Flow Debugger.

Task 13/14. seed-mes-alarm-demo.sh builds a template whose three computed alarms differ in
how they acquire the flag (template --mes-reportable, nothing, instance override over a
template false), a site Call script projecting them through Alarms.CurrentAsync() /
MesReportableAsync(), and two inbound methods + a scoped API key. Idempotent by name lookup.
verify-mes-alarm-demo.sh drives the real inbound HTTP surface: PASS 14/14 on the docker rig
(migration 20260911135501_AddAlarmMesReportable applied at boot). Playwright
AlarmOverride_MesReportable_RoundTrips passed. Results + the facts the gate established are
in design doc section 8.

Moves the legacy BTDB MachineAlarm.FlaggedForMES lookup onto TemplateAlarm.IsMesReportable
(instance-overridable), surfaces it as ScriptAlarm.IsMesReportable / Alarms.MesReportableAsync(),
and adds an AlarmStatus inbound method demo on the docker rig. Native alarms stay on the
severity band (no per-alarm row).

A null resetValue encoded to null, which wrote an empty string and then handed the
waiter a null target (= any change), fast-pathing on the stale cache and reinstating
the race the overload exists to close. The context parameter is now non-nullable and
the accessor throws ArgumentException before any write. Also: additive-timeout note on
all surfaces, batch-failure message no longer names the bool overload, and the
error-message/batch-failure branches are pinned.
Claude-Session: https://claude.ai/code/session_01XPsuy2ZZ5Gbyfpt8PrK5BV
The MES/Delmia handshake fast-paths on the previous run's cached CompleteFlag
because the reset write has not echoed back before the wait registers. An
edge-triggered wait is rejected (a subscription can swallow the reset when the
device flips inside one sampling interval); the fix encodes the reset leg inside
a new WriteBatchAndWaitAsync overload that observes the reset echo before writing
the trigger and returns a phase-aware HandshakeResult.

The Run-inbound-API-method pane rendered one text box per top-level schema
field and coerced the text on the page; an array/object field went through
JsonNode.Parse and, on failure, was SENT AS A STRING, while an empty box was
silently dropped. A required array-of-object parameter (MesMoveOut WorkOrders)
could not be entered at all — QA runs reached the site with "WorkOrders":[].
- The method pane now renders the same shared ParameterValueForm the script
pane uses (typed inputs, nested groups, add/remove list item editors,
$ref:lib: resolution, inline validation), keyed on the method id so a change
of method remounts it. The page keeps ONE value tree and BuildParameters()
serializes it as-is; the flat _inputs / Coerce() / SetInput path is deleted.
- Form | Raw JSON toggle: raw mode is a Monaco json editor for the whole
request body, given the method's root schema for completion, parsed and
schema-validated (InboundApiSchema.Validate) on every edit with the error
inline. Entering raw mode seeds the editor from the tree; leaving it
re-mounts the form over the last valid tree.
- Run is disabled while the form or the raw document is invalid (a required
field left empty disables Run before the first keystroke).
- localStorage per-method entry stores the value tree; on restore it is
validated against the schema and dropped if invalid, which also retires the
pre-#37 flat string-per-field entries.
- ParameterValueForm.ToJsonSchema / JsonElementToObject made internal static
for page reuse.
- Tests: 7 new bUnit tests (WorkOrders array-of-object round-trip to the
RunMethodAsync payload, required list-item gating, invalid raw JSON blocks
Run + shows parse/schema/non-object errors, valid raw JSON sent verbatim and
survives the switch back to the form, method switch resets, persisted tree
restored, legacy flat entry dropped); existing method-pane tests moved to
the form's #param-<field> ids and fill the required field before Run.
Playwright smoke selector moved to #param-Text.
- Docs: design doc, Component-CentralUI.md entry-points bullet, CLAUDE.md.
CentralUI.Tests 1425/1425 green; Playwright project builds.

Both driven from the Mac over the winrm CLI (WinRM 5985 + SMB 445, no helper
on the boxes). Migration 53->55; the first Central boot encrypts
DataConnections.PrimaryConfiguration (dp:protocol:v1:), so rollback is the
COPY_ONLY DB restore, not a binary swap. QA: all four nodes stopped together,
one shared-DB migration, 2 min 35 s window, preflight against a restored clone.
