AdminUI density/layout sweep (§1d follow-through) — 2026-08-10

Follow-through of the /hosts density rework: the §1d scan (four parallel read-only agents, 62 files) applied to the rest of the AdminUI. Playbook: ../scadaproj/admin_ui_cleanup.md §1d + §2 "Density fixes". Prior context: 2026-08-10-adminui-ui-sweeps.md (structure sweep) and the /hosts rework commit 34d60c41.

Scan verdict

• Zero unguarded [..N] slices anywhere (all existing slices are length-guarded or Guid-fixed).
• Cluster pages: no A/B/D defects at all; 3 C items.
• The dominant class is C — unbounded backend/free text (~17 sites), concentrated on the fault-triage surfaces (/alerts, /fleet, /script-log, alarms-historian, DriverStatusPanel).
• Two structural defects: Scripts.razor (inline <details> source dump + identity slam — the /hosts shape) and EquipmentPage.razor (only authoring page with no panel idiom + bare RawPath column).
• Deliberate designs kept: RawManualTagEntryModal colspan config sub-row (documented, inside modal-xl — a fix means stacked modals), VirtualTagModal inline Monaco card (collapsed by default, own card boundary).
• Style-only residual (not §1d, not in this sweep): Deployments.razor is off the panel idiom (bare <h1> + Bootstrap table).

Task 1 — mechanical truncation sweep (Abbreviate + title)

All DisplayText.Abbreviate(value, N) + full text on title; behavior byte-for-byte.

File:line	Value	N
Pages/Alerts.razor:84	alarm Message	80
Pages/Fleet.razor:92	FailureReason	80
Pages/ScriptLog.razor:71	log Message (mono)	120
Pages/AlarmsHistorian.razor:41	drain LastError	80
Shared/Drivers/DriverStatusPanel.razor	op-result chip — truncate in ShowOpResult choke point, title on chip; also :41 SignalR _error	60
Pages/Certificates.razor:77-78	Subject / Issuer DNs	48
Pages/RoleGrants.razor:65,96,24	LDAP group DNs, SearchBase	48
Pages/Clusters/ClusterAcls.razor:88	ACL Notes	60
Pages/Clusters/ClusterOverview.razor:49,100,102	cluster Notes (120), Host (30), ApplicationUri (40)	—
Pages/Clusters/ClusterRedundancy.razor:128	ApplicationUri	40
Pages/Account.razor:63	group-DN chips	40
Pages/Clusters/ClusterAudit.razor:55-57	add title to the already-ellipsized DetailsJson cell	—
Shared/Drivers/Pickers/SqlAddressPickerBody.razor:208-211	composed TagConfig JSON <code>	64
Shared/Drivers/Pickers/SqlAddressPickerBody.razor:159-162	_openError → adopt the sibling truncated-chip + title pattern	60
Shared/Drivers/DriverTagPicker.razor:19-22	footer CurrentAddress	60
Picker Result <code> lines (AbCip:75, TwinCAT:64, OpcUaClient:57, Galaxy:95, FOCAS:109)	browsed address	64

Task 2 — Scripts page: <details> expander → source dialog + two-line identity

Pages/Scripts.razor: replace the per-row inline <details>/<pre> source dump with the Bootstrap modal pattern (modal-backdrop fade show + modal fade show d-block, modal-lg, one at a time); list rows get the stacked identity (name first line, mono id + hash beneath, chips with the name). Hold only the open row's ScriptId; re-resolve from current data every render (self-closes if the script vanishes).

Task 3 — EquipmentPage: adopt the panel idiom + bound the RawPath column

Pages/Uns/EquipmentPage.razor: wrap each tab body in <section class="panel"> + panel-head (Details tab: Identity and OPC 40010 as two panels, dropping the <hr>), matching ScriptEdit's shells; Abbreviate(r.RawPath, 48) + title at :166. Behavior byte-for-byte — tab switching, all bindings, buttons, modals unchanged.

Verification

Merged-tree full build + AdminUI.Tests; live gate on docker-dev (both centrals rebuilt) with at least one faulted/erroring row on screen (§1d realistic-data rule): /alerts, /fleet, /scripts dialog open/close, equipment page tabs, Sql picker footer.
