Three layers were each blind to nested composition in different ways:
- FlatteningPipeline only loaded compositions for templates in the parent's
inheritance chain, so depth-2 composed attributes (e.g.
Pump.AlarmSensor.SensorReading) never materialized. Walk composed chains
breadth-first so the flattener's nested step has the data it needs.
- InstanceConfigure's alarm trigger picker was fed only direct, non-locked
attributes, hiding inherited and composed-member paths. Feed it the full
flattened attribute list via FlatteningPipeline.
- ValidationService.ExtractAttributeNameFromTriggerConfig only recognized
"attributeName", silently passing alarms still using the legacy
"attribute" key. Accept both keys, matching FlatteningService,
AlarmActor, and AlarmTriggerConfigCodec.
Replaces the per-row JSON textbox with an Edit button that opens a modal
hosting the full AlarmTriggerEditor. The editor pre-populates with the
merged inherited + override config so the operator sees the effective
state, not the override delta.
On Save:
- HiLo: diff against inherited, store only changed keys
- Binary trigger types: whole-replace if the edited config differs
Value comparison in the diff is type-aware (decoded strings, numeric
GetDouble) so JSON-escape differences (e.g., literal em-dash vs —)
don't produce false-positive diffs that pollute the override JSON.
FlatteningService.MergeHiLoConfig is now public so the UI can pre-merge
the editor seed; new public DiffHiLoConfig handles the symmetric
direction. +2 encoding tests cover the new equivalence behavior.
The override row's summary column shows the diff'd keys + priority chip
so operators see what's overridden at a glance.
Adds an Alarm Overrides card to the per-instance Configure page (next to
the existing Attribute Overrides and Connection Bindings cards). Each
non-locked template alarm gets a row showing its trigger type, inherited
config, and inputs for an override JSON + priority override. A Clear
button removes the override; the Save Alarm Overrides button upserts
all dirty rows.
The HiLo merge / binary whole-replace semantics are surfaced via the JSON
placeholder hint per trigger type. Wired to the existing
InstanceService.SetAlarmOverrideAsync / DeleteAlarmOverrideAsync flow.
Single /deployment/topology page replaces /deployment/instances (legacy URL
preserved as a secondary @page directive) and the /admin/areas* CRUD pages.
TreeView with Site → Area → Instance, V1–V7 visual guide (bi-building /
bi-diagram-3 / bi-box), always-visible empty containers, search dim, F2
inline area rename, and right-click context menus per node kind (Add Area,
Move to Area…, lifecycle actions, etc.).
Adds AreaService.MoveAreaAsync with cycle prevention, same-site enforcement,
and name-collision check at the new parent. Instance rename intentionally
out of scope — UniqueName is the site-side actor identity, requires its own
design pass.
Move connection bindings, attribute overrides, and area assignment from
inline expandable rows on the Instances table to a separate page at
/deployment/instances/{id}/configure for a cleaner, less cramped UX.
