+# UI patterns
+
+Reusable patterns used across the operator console.
+
+## Three-layer view identification
+
+See [ADR-0009](../../decisions/0009-no-redundancia-titulos.md) for the full rationale.
+
+| Layer | Function | Element |
+|---|---|---|
+| 1 | Navigation (where am I in the product?) | Active pill in left rail |
+| 2 | Mode (what domain is this view in?) | Title strip in topbar (color shifts per domain) |
+| 3 | Operational context (what's happening here right now?) | `.ctx-strip` with badge + dynamic data |
+
+The panel-level `
` "▸ NAME" is **gone**. Don't reintroduce it.
+
+For multi-zone views (e.g. forensics), inner `
` headers are kept because zones coexist on screen.
+
+## Compact context strip
+
+Used at the top of every panel. Pattern:
+
+```html
+
+
+ DYNAMIC INFO HERE
+ optional info-bearing sub-line, no descriptive prose
+
+
+
+```
+
+The badge contains **dynamic info** (states, counts, target endpoints, branch/sha). The sub-line is optional and only when it adds info. Never used for descriptive prose explaining what the view does — that's redundant with the rail.
+
+## Full-screen wizard mode
+
+Used for first-boot wizard and camera onboarding. The console chrome (rail, topbar, status strip) is hidden when in wizard mode.
+
+```html
+
+
+
+
+
+```
+
+Activation via `body.classList.add('wizard-on')`. Deactivation reverts to normal console.
+
+For demos, both wizards have a floating toggle button at the bottom right. In production these don't exist — the wizard appears automatically on first boot, and disappears once provisioning is complete.
+
+## SCADA-style live diagram (SYNOPSIS)
+
+The landing view is a hand-tuned SVG diagram of the site's hardware and services. Conventions:
+
+- **Components** as rectangles with rounded corners (`rx="14"` for major devices, `rx="6"` for small chips).
+- **VLANs** as dashed colored halos around groups of components.
+- **Service chips** as small rounded rectangles inside their host device, with a status pulse dot on the right edge.
+- **Flows** as `stroke-dasharray` lines with `flow-line` animation. Direction arrows via SVG `marker-end`.
+- **Gauges** at the bottom: half-circle SVG paths with the value as text below.
+
+Hand-tuned coordinates for now. If the diagram grows beyond ~10 components, consider migrating to a layout library (e.g., Cytoscape.js) but accept the loss of brand polish.
+
+## Chat with ghost-text autocomplete
+
+Forensic and transcript queries use the same pattern:
+
+```html
+
+
+ user typed text
+
+ suggested completion
+
+
+
+ TAB ACCEPT
+ ↵ RUN
+ ⌘K COMMANDS
+
+```
+
+Suggestions come from the agent backend, contextual to known cameras / speakers / topics / time ranges.
+
+## Agent pipeline visualization
+
+When a query is decomposed into sub-queries, render the pipeline as:
+
+```html
+
+
+ ✓
+ nlp.search(topic="contrato Acme")
+ 94ms
+
+
+
+```
+
+States: `done` (green check), `run` (running, animated), `pending` (dimmed circle), `fail` (red).
+
+Communicates "the system is doing work, here's what" and demonstrates the multi-AI fusion.
+
+## Timeline with markers
+
+Used for forensics and transcript playback.
+
+- **X-axis**: time, with sparse axis labels (5-10 ticks).
+- **Markers**: vertical lines at hit positions, color-coded by type.
+- **Playhead**: distinct color (cyan or warn-cyan), fixed during playback.
+- **Swimlanes** (when multiple sources): horizontal bands per source, one row each.
+
+Click on marker → jump player to that timestamp + scroll transcript/event list to corresponding entry.
+
+## Player shell
+
+For both video clips (Blocao) and audio segments (transcript):
+
+```
+[ play | pause ] [ scrubber with progress overlay ] [ time MM:SS / TOTAL ]
+[ controls row: ±5s, prev/next turn, speed, follow playhead, secondary actions ]
+[ live caption / metadata bar ]
+```
+
+The shell is shared; what differs is the visualization above the scrubber (frame for video, waveform for audio).
+
+## Health test items with expandable detail
+
+```html
+
+ !
+
FPS per camera
expected 15.0 ±10%
+
3/4 IN RANGE
+
+
⚠ WARNING · cam-04 below threshold
+ Body explaining the issue.
+
+ Likely cause: ...
+
+
+
+
+
+
+
+```
+
+OK items don't expand (no info to show). Warn/err items expand with detail + suggested actions.
+
+## When to break a pattern
+
+Patterns are starting points, not handcuffs. Break a pattern when:
+
+- The data shape genuinely doesn't fit (e.g., a 1000-row table doesn't belong in a card).
+- The user's primary question can't be answered with the standard layout.
+- A custom visualization is more memorable for a key moment (SYNOPSIS itself is a "broken pattern" relative to the rest of the console).
+
+Document any pattern break with an inline code comment and, if it sticks, promote it to a new pattern in this file.
