# Command Deck Header Refinement

Simplified the overview command deck header into a compact status bar that keeps live state, last tick time, replay switching, and active filter context near the top of the page.

## Summary

The accepted live-mode variant replaces the heavier command deck header with a calmer two-line command bar. The top line now carries the product label, live connection chip, last-update chip, and replay toggle. The second line keeps the evidence-console context, focused ticker, and the active filter state.

## Changes Made

- Reworked `CommandDeckHeader` markup from a three-column brand/brief/control layout into a compact two-line status bar.
- Added active filter chips for selected option contracts and ticker filters, with hover/focus clear buttons.
- Moved accepted live styling into `globals.css` and removed temporary live-mode wrappers, scripts, and session files.
- Added responsive overrides so compact status chips wrap without becoming full-width controls on mobile.

## Context

This change came from an Impeccable live session on the overview page. The selected element was the command deck header. The accepted direction was variant 2, a simplified command bar that keeps operational controls close to the top while reducing decorative weight.

## Important Implementation Details

Contract filters When an option contract is focused, the header renders its label and clears with `setSelectedInstrument(null)`.
Ticker filters When ticker text is active, the header renders `Ticker: value` and clears with `setFilterInput("")`.
Filter affordance The clear button appears on hover or focus-within, preserving a quieter default chip while staying keyboard reachable.
Motion The hover transition is included in the existing reduced-motion terminal control block.

## Relevant Diff Snippets

Rendered with `@pierre/diffs/ssr` using `preloadPatchFile`. These are the focused file diffs for the accepted header implementation.

### Diff 2

## Expected Impact for End-Users

Users get a quieter command deck with live status, last update, and replay switching preserved in the first scan line. Active filters become easier to notice and clear without adding another permanent button to the header.

## Validation

- Passed `bun --cwd=apps/web run build`, including production compile and TypeScript.
- Verified live session cleanup removed temporary Impeccable source markers and the injected live script.
- Observed existing browser fetch failures for unavailable local backend endpoints; these were not introduced by this change.

## Issues, Limitations, and Mitigations

- The live browser continued logging existing failed fetches for option support and alert evidence while backend services were unavailable. The web production build still passed.
- The no-filter state remains textual: `No active filter`. This keeps the status explicit, but it can be revisited if the header should hide inactive filter context entirely.

## Follow-up Work

- Beads: `islandflow-9ns` tracks this completed refinement.
- Consider aligning the topbar ticker input and command deck filter chip language if the same filter state should appear in both places.
