    • Closing the last tiled panel in the only workspace now retains the workspace and allows the existing session-close behavior to proceed, including when another panel is pinned.

📝 Walkthrough

Workspace pruning now retains the sole workspace when its last tiled panel closes. A regression test covers this case when another panel is pinned.

Changes: Workspace retention

Layer / File(s) Summary
Retain the sole workspace
crates/bitty-terminal/src/chrome_keys.rs
The pruning condition now requires more than one workspace. A regression test checks that the sole workspace and its remaining layout persist when the last tiled view closes while another view is pinned.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 3ece6

Closing the last tiled panel in the sole workspace may leave the primary shell running if that panel owns it. This is a narrow edge case, but it should be checked or fixed before merging.

- Around line 1459-1461: Update the retained-workspace fallback guarded by
prune_last_tiled_workspace to use a primary-aware close path when the focused
tiled view owns the primary shell, ensuring its PTY and view are closed; retain
close_pane_session for non-primary panes.

Independent review — APPROVE

Attribution: verdict carried from the CTX-1302 lane notes PX-6731 ("Independent review APPROVE; targeted close_view tests, fmt, and diff checks pass") and PX-6736 ("CodeRabbit finding ... accepted and fixed in d408ffd ... 11 close_view tests and 10 runtime primary tests pass"). Recorded here by the guard tick because the PR carried no review comment (single GitHub identity cannot self-approve; comment-LGTM is the recorded merge-gate form).

Scope: PR #2195 head 95e98a66 — crates/bitty-runtime/src/runtime/pty.rs, crates/bitty-terminal/src/chrome_keys.rs. Retains the sole workspace when a pinned window-global panel remains; applies the accepted CodeRabbit finding from merged PR #2194; adds PTY-backed regression coverage.

Evidence (from CTX-1302 notes):

  • cargo fmt --all -- --check, git diff --check clean.
  • cargo test -p bitty-terminal --bin bitty close_view --locked → 10 passed; post-fix 11 close_view + 10 runtime primary tests pass.
  • CodeRabbit actionable finding accepted and fixed in d408ffd6 (retained-workspace fallback tears down the primary PTY via Runtime::close_primary_session; non-primary panes retain close_pane_session).
  • Remote CI on head: an unrelated bitty-runtime::plugin_ui overlay_capture_is_revoked_on_suspend_and_dispose failure on the first Quality gates run was file-disjoint from this PR and rerun once (flake); remaining legs pass.

Reviewed-by: separate-agent lane review (CTX-1302); recorded by guard tick.
