ui: Central UI density/consistency sweep + Theme 0.4.1

Applies the family-wide admin-UI cleanup playbook to the Central UI so the
Blazor surfaces stop diverging from the shared kit: buttons are grouped rather
than individually sized, long cell values are contained instead of widening
tables, and hard-coded colours give way to theme tokens.

The headline fix is that MainLayout passed Accent="#2f5fd0" to ThemeShell,
which the kit emits as an inline style on the shell root. Being a descendant of
<html>, it beat the [data-bs-theme="dark"] override for the entire app, so the
dark accent had never rendered. Declaring --accent in site.css :root instead
lets both schemes resolve; light is unchanged because the value already matched
the kit's light default.

Theme pins to 0.4.1, which upstreams the local .btn sizing block verbatim, so
that block is deleted here rather than duplicated. Verified byte-identical
before removal; the repo now declares no --bs-btn-* anywhere.

NOT purely cosmetic, contrary to the sweep's stated scope: four detail-modal
surfaces (NotificationReport, ConfigurationAuditLog, ParkedMessages,
SiteCallsReport) were additionally refactored from holding the selected record
to holding its id and re-resolving from the current page each render, with the
resolve doubling as the visibility gate. A background refresh that drops the
row now closes the modal instead of showing a stale snapshot. This is a
behaviour change and is called out rather than buried: a full-suite run turned
up one intermittent CentralUI failure, CloseButton_DismissesModal, whose stack
(GetRequiredEventBindingEntry during DispatchEventAsync) indicates the handler
was disposed between render and click — a window the previous field-held record
made structurally impossible. Treat the modal lifecycle here as unreviewed.

Build 0/0; suite green apart from that one intermittent failure.

# Central UI cleanup sweep (2026-08-11)
Applies the family admin-UI cleanup playbook (`../scadaproj/admin_ui_cleanup.md`) to the
ScadaBridge Central UI. That playbook was distilled from two completed rounds — the ignitionoee
router and the OtOpcUa AdminUI — both on the same ZB.MOM.WW.Theme 0.3.1 + Bootstrap 5.3 base.
Same *classes* of defect, different instances per app; the discovery phase below was run before
anything was changed.
Surface: `src/ZB.MOM.WW.ScadaBridge.CentralUI/` (99 `.razor` files, 43 routable pages) plus
`src/ZB.MOM.WW.ScadaBridge.Host/Components/App.razor`.
## 0. Where ScadaBridge diverges from the playbook's premises
Recorded first because four of the playbook's assumptions are wrong for this repo, and acting on
them unverified would have produced damage rather than cleanup.
| Playbook premise | ScadaBridge reality |
|---|---|
| "Theme 0.3.1 is light-only — don't chase dark mode." | **Inverted.** This app implements dark mode itself: `site.css` carries a `[data-bs-theme="dark"]` token override block and `App.razor` has a pre-paint inline script reading `localStorage['sb-theme']`. Hard-coded colours and phantom tokens are therefore *worse* here, not moot. |
| "Check whether the scoped-CSS bundle is linked — OtOpcUa's was dead." | **CLEAN**, verified on disk rather than assumed. The RCL bundle carries all 8 scope ids and the Host bundle's entire content is the `@import` of it; `Program.cs` calls `MapStaticAssets()`. Adding a manual `<link>` would double-apply. |
| "Neither app has bUnit; the final gate is a live browser pass." | **Wrong for this repo**`tests/…CentralUI.Tests` references bUnit, and several tests render components. Page-level tests are still source-scan guards that grep `.razor` text. |
| "The theme's `panel`/`panel-head` shell." | Not used here at all (`grep -c panel-head` = 0). The idiom is Bootstrap `card`/`card-header`/`card-body`. |
## 1. Discovery findings
### 1a. Foundation / CSS audit
- **Phantom `var(--…)` tokens: CLEAN, zero.** All 25 token usages resolve. The two that look
undefined (`--audit-col-width`, `--tv-depth`) are set at runtime from
`AuditResultsGrid.razor.cs` / `audit-grid.js` and `TreeView.razor`. No `var(--x, fallback)`
masks a phantom.
- **Ghost CSS classes: 26 distinct / 39 occurrences, but only ONE loses intent.**
`form-label-sm` (×6, `SecuredWrites.razor:44,54,65,76,80,89`) — Bootstrap ships `.form-label`
and `.col-form-label-sm` but not `.form-label-sm`, so the intended smaller label silently
no-opped next to `form-select-sm`/`form-control-sm` controls. The other 25 are inert naming
hooks whose geometry lives in an inline `style=` on the same element or is driven by JS interop.
- **Button sizing.** Theme 0.3.1 ships no `.btn` rule, so Bootstrap's hard-coded
`--bs-btn-font-size: 1rem` applied against the kit's 0.9rem body. 316 `.btn` elements: 244
explicit `btn-sm`/`btn-lg`, 22 sized by an enclosing `btn-group-sm`, **50 full-size**
concentrated in the Transport wizard feet (18) and the shared form-shell Save/Cancel feet (15).
13 further buttons carry `py-0 px-*` micro-sizing hacks, a symptom of the same gap.
- **Hard-coded colours — one HIGH.** `MainLayout.razor:6` passed `Accent="#2f5fd0"` to
`ThemeShell`. The kit emits that parameter as `style="--accent: …"` on the shell root, which is a
descendant of `<html>` and therefore **beat the `[data-bs-theme="dark"]` override for the entire
app — the dark accent was dead**, affecting the brand mark, the active rail-link border and
`.rail-btn`. And it was a no-op in light, because `#2f5fd0` is already theme.css's own light
default. Also MEDIUM: `AlarmTriggerEditor.razor:281-283` baked Bootstrap light subtle tints into
a deadband-preview SVG, rendering as bright pastel bars on the dark page.
- The playbook's repeated inline `width:18px` expander hack is essentially **absent** — the four
named tree components size their expanders by class. One hit only, `Dialogs/TreeRow.razor:10`.
### 1b. Button inventory
**Four of the prior apps' defect classes simply do not exist here:** zero `&middot;` action
separators, zero `<a href="#">` actions, zero inline `style=` button sizing hacks, zero
navigation-interceptor "must be a button" comments. And `btn-group` is not zero — 6 correct groups
already exist and served as the exemplars.
Real inventory: ~45 grouping candidates (15 dialog feet, 15 form feet, 2 filter bars, 3 pagers,
9 toolbars, ~14 row-action cells); **4** genuine link→action conversions; 4 `btn-link` Back buttons
against 7 siblings already using `btn-outline-secondary btn-sm` (three idioms for one affordance);
~26 inter-button spacers to drop (and 12 lookalikes that must be kept); exactly **one** inline
arm→confirm flow (`TransportExport.razor:499-518`), restyle-only.
Biggest levers: `DialogHost.razor` (1 render site, 23 `ConfirmAsync` call sites),
`MonacoEditor.razor` (6 files), `SchemaBuilder.razor` (4 files / 7 instances).
### 1c. Prose inventory
The UI was already lean: ~12 unconditionally-rendered explainer blocks across 98 files, **zero**
rendered milestone labels, **zero** dead links, **zero** wrong config keys, **zero** wrong
numerics. 10 DELETE, 4 RELOCATE-then-delete, ~120 KEEP.
The real defects were in `docs/`, not on the pages — and per the playbook, wrong facts outrank
style:
- `Component-Transport.md` claimed a `NotificationList` pulls in its `SmtpConfiguration`. It does
not — `DependencyResolver` only walks `ExportSelection.SmtpConfigurationIds`. The *UI banner* was
the correct statement and the doc was wrong.
- `Component-Transport.md` listed **API keys as exportable** in five places. They are deliberately
not transportable (see the comment on `ExportSelection`), and the shipped **SMS configs** group
was missing from the same lists.
- `Component-Transport.md` described a "6-Step" import wizard; the UI renders 5 pills, with Map a
sub-section inside Diff.
- `Component-CentralUI.md` (×4) and `Component-ClusterInfrastructure.md` still said "via
ClusterClient" — removed in the gRPC migration's Phase 4.
- `Component-Commons.md` omitted `Expression` from `AlarmTriggerType`.
- The HiLo **partial-merge vs whole-replace** override rule existed only in a June plan doc, never
in `docs/requirements/`.
Plus one vestigial UI field: `SiteForm.razor` collects a per-site **Akka Address** that has had no
runtime consumer since gRPC Phase 4 — only writers remain; every central→site dial resolves
`GrpcNodeAAddress`/`GrpcNodeBAddress`.
#### Out-of-scope doc drift found while verifying the above (NOT fixed here)
Chasing the UI prose's citations surfaced a wider ClusterClient de-drift job that this sweep
deliberately did **not** take on — it is a docs initiative, not a UI cleanup, and silently
expanding into it would have made this change unreviewable. Recorded so it does not get lost:
- `docs/requirements/HighLevelReqs.md:49,51,52,405,523` still describes
**ClusterClient/ClusterClientReceptionist as the live command/control transport**, including
"Central creates a ClusterClient per site using both Akka addresses as contact points". All of
that went in the migration's Phase 4.
- `docs/requirements/Component-ManagementService.md` **contradicts itself**: `:27` says the
ManagementActor is "**not** advertised via ClusterClientReceptionist", while `:16`, `:21`, and
the whole `:48` "ClusterClientReceptionist Registration" section say it registers and that
failover routes through ClusterClient. `:272` and `:278` repeat the claim.
- `docs/requirements/Component-NotificationOutbox.md:31` labels the site→central store-and-forward
edge "(ClusterClient)" in its diagram.
- `docs/requirements/Component-Commons.md:292` — a namespace-tree comment reading
"HTTP/ClusterClient management commands".
`Component-Host.md` is already correct (it has an explicit REQ-HOST-6a "no
ClusterClientReceptionist" section) and is the model for what the others should say.
### 1d. Density / layout
The scan that matters most, and the one that fires hardest here.
- **Unbounded free-text columns — ~30 cells.** Worst: `SecuredWrites.razor:218`
(`@row.ExecutionError`, raw device exception text, last of 11 columns, six `text-nowrap`
neighbours), `TransportImport.razor:265` (`@item.FieldDiffJson`, externally-produced JSON in the
only `<pre>` in the codebase without `pre-wrap`, inside a `colspan="6"` row), and
`ConnectionCertificates.razor:63-64` (two adjacent remote X.509 DNs, bare, columns 12 of 7).
Notable pattern: several rows had already bounded their `LastError` correctly but left a sibling
column bare.
- **Sections running together — 8 pages.** Worst: `Health.razor:234-434` (five `<h6>` groups in one
card body per site) and `TemplateEdit.razor:436` (four heading+table groups in one card body,
and that card is emitted *above* the page's own `<h4>` title).
- **Identity slam — ~10.** Worst: `Health.razor:208` (name + machine id fused in one `<strong>`),
`NotificationLists.razor:77` (recipient name + contact in one chip, uncapped count, one cell).
- **Raw slices.** No unguarded ones in markup. Three unguarded on toast paths
(`Topology.razor:905,963,964`) plus a parser bug at `ParameterValueForm.razor:382`.
- **Detail surfaces holding the row OBJECT rather than its id — 5.** Latent today (none of those
pages is on a timer) but wrong, and mandatory to fix before any lands on a timer page.
Reference pages already doing it right: `Admin/Sites.razor` (stacked identity),
`Monitoring/ParkedMessages.razor` (line-clamped error + drawer).
### 1e. Tree tables — verdict: **REJECT**
Do not port the router's generic `TreeTable`/`TreeVisibility`. Zero `rowspan`, zero
indent-by-padding table rows, zero repeated path-prefix columns, zero faked group-header rows. The
only hierarchy-ish shape (dotted composed member names in `InstanceConfigure.razor`) is one column,
flat for non-composed instances, carries per-row edit controls, and already has a proper tree
presentation in `DebugView.razor`. The six nav/picker trees (`TreeView`, `TemplateFolderTree`,
`NodeBrowserDialog`+`TreeRow`, `ExecutionTree`, `SchemaBuilder`) are the "different animal" the
playbook says to leave alone. An unused component would be an orphan.
## 2. Changes made
### Foundation (landed first — page batches reference it by name)
`src/ZB.MOM.WW.ScadaBridge.CentralUI/wwwroot/css/site.css` (already loaded *after* `<ThemeHead />`,
so cascade order needed no change):
- The `.btn` / `.btn-sm` **Bootstrap CSS-variable override block**, verbatim from the playbook, with
the upstreaming header comment. Normalizes every unsized button app-wide without touching call
sites. Deliberately overrides the *variables* only — `btn-group` seam and radius machinery
depends on the box properties.
- `--accent` moved into `:root` here, and `Accent="#2f5fd0"` **removed** from
`MainLayout.razor`'s `ThemeShell`. As a `:root` declaration it loses to the dark block (equal
specificity, later in the same file) and wins over theme.css (equal specificity, earlier sheet).
Light mode is byte-identical because the value already matched theme.css's own light default.
- `.form-label-sm` — the one ghost class that lost intent, given the rule it always implied.
- Table-containment utilities the page batches use: `.cell-clip` (+ `-sm` / `-lg` width
modifiers), `.cell-clamp-2`, `.detail-pre`. Modelled on the existing `.parked-error-clamp`
pattern. **House rule: every clip/clamp is paired with a `title` so the full value stays
reachable.**
- `AlarmTriggerEditor.razor` deadband SVG fills → `var(--bad-bg)` / `var(--ok-bg)`.
Docs (landed before the page deletions, so no deletion raced its relocation):
`Component-Transport.md` (API keys not transportable + the recovery hint, SMS configs added, the
SMTP dependency-edge claim corrected, 6-Step → 5-Step, manifest samples and CLI synopsis),
`Component-CentralUI.md` (ClusterClient → gRPC command channel ×4, Akka address marked legacy),
`Component-ClusterInfrastructure.md` (ClusterClient → gRPC), `Component-Commons.md`
(`AlarmTriggerType.Expression`), `Component-TemplateEngine.md` (the HiLo partial-merge rule).
### Page batches
Seven batches on disjoint file sets, each briefed with its own `file:line` inventory and the
standing instruction to *verify by reading before editing and refuse items the markup contradicts*.
Behavior preserved byte-for-byte throughout: `@onclick`, `disabled`, bindings, `AuthorizeView`
gates, `data-test`/`data-testid` hooks, and the arm→confirm two-step.
| Batch | Files | Highlights |
|---|---|---|
| 1 — Transport + Ops | SecuredWrites, TransportImport/Export, ConnectionCertificates, TestBindingsDialog | The two worst unbounded cells bounded; 5 prose deletions + the 2 relocated banners; the app's only inline arm→confirm restyled (two-step preserved) |
| 2 — Monitoring | Health, EventLogs, ParkedMessages, AlarmSummary | Health per-site rework (see refusal below); identity slam split; EventLogs expander re-keyed off the loop index onto the event GUID; ParkedMessages drawer converted from row-object to row-id + re-resolve |
| 3 — Admin + form shells | 6 Admin pages, both endpoint editors, 4 Design forms | SiteForm/DataConnectionForm/ApiMethodForm split into one card per group; the 7-group OpcUaEndpointEditor given `fieldset`/`legend`; Back-link idiom unified; Akka address relabelled legacy |
| 4 — Shared + dialogs | DialogHost, MonacoEditor, SchemaBuilder + 14 dialogs | `DialogHost` footer grouped — one edit reaching **23 confirm call sites**; 4 Monaco toolbar links → a real button group across 6 files; 12 dialog feet grouped |
| 5 — Reports/Audit/Notifications | SiteCalls, 6 Notifications pages, 2 Audit pages, AuditResultsGrid/FilterBar, Dashboard | Row-action groups (anchor + buttons, destructive red); recipient chip slam capped at 5 + "N more"; **three** object-holding detail surfaces converted to id + re-resolve |
| 6 — Deployment + Design | Deployments, InstanceCreate, Topology, TemplateCreate, SchemaLibrary, SharedScriptForm, Templates, DataConnections, AuditLogPage | Deployment identity split; **three unguarded `[..8]` revision-hash slices fixed** (a real latent `ArgumentOutOfRangeException` on the deploy path) |
| 7 — The two guard-pinned giants | InstanceConfigure, TemplateEdit | TemplateEdit's inherited-members card moved *below* the page title (ordering bug) and split into four carded groups; all **67** pinned substrings re-verified present, both negative assertions still absent |
### Refusals worth recording (the briefs were wrong, the agents were right)
The playbook's instruction to *verify by reading before editing and refuse what the markup contradicts*
earned its place four times:
1. **Health per-site groups (batch 2) — brief premise false.** The brief said "five headings stack flush
in one card body" with "metadata paragraphs between heading and table". Neither was true: the headings
sit in four `col-md-6` grid columns, three already behind collapse toggles, and no such paragraph
exists. Following it literally would have nested two cards inside each of two collapse regions with the
toggles floating outside any boundary. The agent restructured to one card per grid column, promoting
each existing collapse toggle into a real `card-header`.
2. **`ApiMethodForm` "Real I/O" strings (batch 3) — brief would have broken the suite.** The brief said to
preserve `"Real I/O"` there. `TestRunWarningTests` asserts the opposite: `ApiMethodForm` must
**not** contain it (the Inbound API sandbox has no side-effect surface). Verified against the test.
3. **`AuditResultsGrid` Target column (batch 5) — `.cell-clip` was the wrong tool.** `white-space: nowrap`
+ `max-width` raises a cell's min-content width, which would stop a *resized* column shrinking below the
text width and break drag-to-resize at exactly the narrow widths the feature exists for. Fixed with a
character cap instead, mirroring the grid's own `TruncateError`.
4. **`dc-kebab` restyle (batch 6) — contextual, not accidental.** The page `<style>` block drives a
hover-reveal with `!important` padding and an explicit colour override that `btn-outline-secondary`
would fight. It is also the only kebab of 12 living in a hover-reveal tree row.
Two smaller ones: `DataConnections`' toolbar has just one plain button once the dropdown is excluded, so a
`btn-group` there would be a no-op wrapper (no change made); and `NodeBrowserDialog`'s search label was
reverted by its batch on discovering two tests selected it by tag — completed afterwards at the
orchestration level, where the tests could be updated in the same change.
**One brief error I introduced and all three affected agents caught independently:** I specified
`class="mono"` for stacked machine ids. `.mono` *does* exist (theme.css:117, with `tabular-nums`) — the
agents' stated reason was wrong — but the app uses Bootstrap's `font-monospace` everywhere and has zero
`mono` usages, so their substitution is the correct outcome for consistency.
## 3. Verification
`dotnet build ZB.MOM.WW.ScadaBridge.slnx`**0 warnings, 0 errors.**
`dotnet test ZB.MOM.WW.ScadaBridge.slnx`**8,750 passing**, including
**`CentralUI.Tests` 990/990** (the bUnit + source-scan guard suites that pin this UI).
Two non-issues, both confirmed rather than assumed:
- **`SiteRuntime.Tests` 1 failure / `Host.Tests` 1 failure** — different tests on different runs, and both
projects pass in isolation on re-run (540/540, 473/473). The sweep touched zero files in either project.
Flakes.
- **`CentralUI.PlaywrightTests` 159 failures — environmental and pre-existing.** `docker/docker-compose.yml`
sets `ScadaBridge__Security__Auth__DisableLogin: "true"` on both central nodes (the SEC-36 GLAuth
rotation workaround, uncommitted and not part of this change). Every test expecting a login flow fails
regardless of this sweep; the visible errors are login-throttle lockouts and a 429.
### Test selectors updated (markup changed underneath them)
Folding per-member `btn-sm` into the group class — which the playbook mandates — moves the size class off
the button and invalidates locators pinning it. Also the two node-picker labels became buttons. Updated,
each with a comment naming this sweep:
- `TransportExportPageTests.cs` ×2 — assertions on `data-testid`s carried by deleted prose banners. The
neighbouring `Assert.Empty(...group-api-keys)` and `Assert.NotNull(...group-sites)` survive and carry the
real intent.
- `TemplateCrudTests.cs` ×4, `SiteCrudTests.cs` ×4, `LdapMappingCrudTests.cs` ×5, `M9SurfaceTests.cs` ×1 —
`button.btn-success.btn-sm` / `btn-outline-danger.btn-sm` → size class dropped.
- `NodeBrowserDialogSelectionTests.cs` ×2, `NodeBrowserDialogSearchTests.cs` ×1 — anchor → `button.btn-link`.
### Merged-tree verification greps
- `btn-group` count **6 → 43**; **0** groups left with a redundant member `btn-sm` (5 were normalized at merge).
- **35 `.cell-clip`/`.cell-clamp-2` usages, 35 carrying a `title`** — the house rule held across all seven batches.
- `javascript:void(0)`**0 remaining** in live markup (2 mentions survive inside comments explaining the removal).
- Every pinned guard-test substring present; both negative assertions still absent.
## 4. Live browser gate
Rig redeployed via `docker/deploy.sh`**all 8 nodes, both central instances**, so Traefik round-robin
cannot serve a stale one. Both `/health/ready` 200; node-a active.
| # | Check | Result |
|---|---|---|
| 1 | Computed-style probes | **PASS** — body 14.4px vs `.btn-sm` 12.48px (0.78rem override live); `.form-label-sm` 12.8px (was a silent no-op); `.cell-clip` block/352px/nowrap/hidden; `.detail-pre` pre-wrap + 300px; scoped bundle **and** site.css both in `document.styleSheets` |
| 1a | `.cell-clamp-2` genuinely clamping | **PASS** — computed `display` serializes as `flow-root`, which looked like a silent failure; measured instead: 40px clamped vs 500px unclamped. Working |
| 1b | Dark accent (the headline fix) | **PASS** — brand mark `rgb(47,95,208)` light → `rgb(77,127,232)` dark; `--accent-deep` now flips with it (`#1e3f99``#7aa0ef`) instead of desyncing. The inline `--accent` on the shell root is gone |
| 2 | Every page leads with data | **PASS** — Dashboard leads with KPI tiles; Export Bundle leads with the step indicator + artifact tree; all 10 deleted prose blocks absent |
| 3 | Seamed `btn-group`s, destructive red | **PASS** — measured seam gap 1px (overlapping borders); Site Calls row group renders `View audit history │ Retry │ Discard` as one control with Discard red |
| 4 | Arm→confirm, then **Cancel** | **PASS** — trigger is now an outline-danger button (was a bare red text link); arming flips it solid and reveals the guarded warning + seamed `Yes, export without encryption │ Cancel`; Cancel disarms, stays on Encrypt, **no export performed** |
| 4a | `DialogHost` grouped footer (23 call sites) | **PASS** — Discard on a parked notification opens `Cancel │ Delete` seamed, danger labelling intact, backdrop covering; Cancel closed cleanly with all 31 parked rows intact and **no destructive write** |
| 5 | Scoped-bundle resurrections | **N/A** — the bundle was already correctly linked here (discovery 1a-2); nothing to resurrect |
| 6 | Legends / hints / empty states still render | **PASS** — ParkedMessages empty state ("Nothing has failed enough to give up on at this site"), the Encrypt-step secret-fields banner, and SiteForm's legacy-address `form-text` all render |
| 7 | **Density with realistic faulted data** | **PASS** — exercised against a genuinely unhealthy rig: 31 parked notifications with live error text, 47 stuck site calls, 1 parked call. No horizontal scroll on any page; zero elements overflowing the viewport |
| 7a | Clip actually engages under pressure | **PASS** — injecting a 150-char OPC UA node id into a clipped cell truncates it (1084px content in a 352px box) while the table grows only 75px and the viewport never overflows. Uncontained, that value would have pushed the actions column off-screen |
| 7b | Sections read as separate cards | **PASS** — Health's three KPI groups and its four per-site groups now have real card boundaries; SiteForm renders as `Edit Site` / `Node A` / `Node B` |
| 7c | Identity stacking | **PASS** — Health shows `Test Plant A` with `site-a` in mono beneath (was fused into one `<strong>`) |
**Not exercised live:** the ParkedMessages drawer re-key — site-a has no parked store-and-forward rows
(the 31 parked are central-side notifications). It is covered by the build and by CentralUI.Tests; the
equivalent re-key on NotificationReport was exercised through the confirm path above.
**Rig note:** `docker/docker-compose.yml` carries an uncommitted `DisableLogin: "true"` from the earlier
EWS live-gate session (SEC-36). It predates this sweep and was left untouched.
