fix: reveal selected agent when cycling the sidebar by ogulcancelik · Pull Request #4355 · herdrdev/herdr

ogulcancelik · 2026-09-18T15:12:33Z

Summary

Reveal agents selected through cycling or direct shortcuts while preserving scroll when already visible.
Defer cross-machine reveals until the destination projection is active, using its filter and sort.
Preserve pending reveals through source restoration, cancel them on another selection, and request a repaint.

Validation

TDD: confirmed failures before fixing off-screen selection, repaint scheduling, destination sorting, and source restoration.
Cover forward/backward navigation, direct selection, cross-machine navigation, cancellation, and visible-target scroll preservation.
just check passed: 3,629 Rust tests, Windows lint, and contract tests. An unrelated plugin capture test failed once, then passed individually and in the full rerun.
Initial sidebar behavior manually verified by Can.

No documentation change: restores expected sidebar navigation behavior.

📝 Walkthrough

Walkthrough

The change defers agent reveals until endpoint activation completes. Navigation reveals agents immediately for the active endpoint and stores pending reveals for different endpoints. Endpoint and pane selection clear pending reveals. Agent scrolling now uses the supplied body height. Tests cover repaint requests, remote activation, sorting, cancellation, and visible targets.

Merge Risk: ⚪ Minimal · up to 04340

The updated navigation behavior preserves deferred reveals across endpoint restoration and includes coverage for activation, cancellation, sorting, repainting, and visible-target scrolling. No merge-blocking risk remains.

Summary

This PR ensures keyboard-based agent navigation reveals the selected agent in the sidebar without disturbing the scroll position when the row is already visible.

Adds variable-height, gap-aware scrolling for endpoint-qualified agent rows.
Defers cross-endpoint reveals until the destination projection is active.
Preserves deferred reveals through unrelated intermediate projection activations.
Cancels stale deferred reveals when another endpoint or pane selection supersedes them.
Adds regression coverage for forward, backward, direct, cross-machine, destination-sort, cancellation, and already-visible cases.
