davsclaus opened a new pull request, #23772:
URL: https://github.com/apache/camel/pull/23772
## Summary
- Add `isStubEndpoint()` to `BacklogTracerEventMessage` API to detect stub
endpoints in tracer events
- Detect stub endpoints in `CamelInternalProcessor` and `BacklogTracer` by
checking endpoint class name (works in both explicit `stub:` and shadow mode)
- Add direction arrows in TUI History tab to distinguish endpoint types:
- `*-->` / `<--*` remote first/last
- `*->` / `<-*` local first/last
- `~-->` / `<--~` stub first/last
- `--->` send to remote endpoint
- `~-->` send to stub endpoint
- Add `n` toggle for route description display in History tab
- Add step count to History and Trace detail titles
- Add `>>` selection indicator in waterfall view with auto-scroll
- PageUp/PageDown now jump 10 steps in waterfall mode
- Show `d` diagram hint in footer when waterfall is active
- Wider route column (25 chars)
- Updated F1 help text with arrow documentation
## Test plan
- [x] Build `camel-api`, `camel-base-engine`, and `camel-jbang-plugin-tui`
- [ ] Run route-topology example with `--stub` and verify `~-->` / `<--~`
arrows appear for stub endpoints
- [ ] Verify `*-->` / `<--*` arrows for real remote endpoints (without
`--stub`)
- [ ] Verify `--->` arrows on regular `to[kafka:...]` steps
- [ ] Verify `n` toggle shows route descriptions
- [ ] Verify waterfall `>>` indicator follows cursor
- [ ] Verify PageUp/PageDown jumps in waterfall mode
- [ ] Verify `d` diagram hint visible in waterfall mode
