New tab showing all circuit breakers for the selected integration, inserted between Endpoints and Health. Supports all three Camel implementations: resilience4j, fault-tolerance, and core (ThrottlingExceptionRoutePolicy). Columns: ROUTE · ID · COMPONENT · STATE · PENDING · SUCCESS · FAIL · RATE% · REJECT - STATE is colour-coded: green=CLOSED, red=OPEN/FORCED_OPEN, yellow=HALF_OPEN - PENDING and REJECT are resilience4j-only - RATE% is resilience4j-only (failure rate percentage) - fault-tolerance shows only ROUTE · ID · STATE (its dev console provides no counters) Sort: press 's' to cycle ROUTE → ID → COMPONENT → STATE. Tab badge shows circuit breaker count; empty table shows "No circuit breakers". Tab numbering shifted: Circuit Breaker=5, Health=6, History=7, Trace=8. All footer hints updated to "1-8 tabs". Health tab gains red "(N DOWN)" badge when any check is DOWN. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…s are open When one or more circuit breakers are OPEN or FORCED_OPEN, the tab title changes to a red '(N OPEN)' badge — same pattern as the Health tab's '(N DOWN)' indicator. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Track failed/s alongside total/s in the sparkline history. Each time slot in the overview chart now renders as two bars side-by-side: - green bar = ok exchanges per second (total - failed) - red bar = failed exchanges per second 30 time slots × 2 bars × width=1 = ~60 columns, preserving the same visual footprint as the previous single-bar chart. Chart title shows current throughput broken down as 'N ok / M failed'. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Setting textValue("") hides the 0/value labels below each bar.
The current numbers are already shown in the chart title.

…orrectly barWidth=1 only fits single digits; with barWidth=2 values 0-99 render inside the bar. Render points reduced from 30 to 20 to keep total chart width roughly constant (20 × 2 bars × width 2 = ~80 columns). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…legend
- Replace single-color sparkline with BarGroup (green=ok, red=failed) bars
- Dynamic tick count: fills available terminal width (up to 60s of history)
- Y-axis scale labels (max, max/2, 0) aligned with bar chart rows
- X-axis time markers (-Ns labels and "now") drawn below the chart
- Styled title legend showing current msg/s, ok count and fail count
- barWidth=1, textValue("") suppresses per-bar numeric labels

The route dev console JSON already includes a "group" field on each route when a route group is set. Parse it into RouteInfo and display it as a dimmed GROUP column between ROUTE and FROM. The column is sortable via the 's' key, cycling in column order: name → group → status → total → failed. COVER value is right-aligned. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Camel returns -1 for mean/min/max processing time when no exchanges have completed yet. Clamp to 0 at parse time so the MIN/MAX/MEAN column never displays -1. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Replaces Color.RED with Color.LIGHT_RED (ANSI bright red) throughout the TUI so that failure states, DOWN health checks, OPEN circuit breakers, failed exchange counts, and error text all render with the same light red that is visible on dark/black terminal backgrounds.

The light red (BRIGHT_RED) does not contrast well against the bar chart background. Revert the chart bars and legend swatch back to the darker Color.RED while keeping Color.LIGHT_RED for text-based error indicators. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
