What

The agent session split header was the only title in the app with a hover pencil and an always-focusable input, so a single click on the split tab dropped a caret into the session name. This makes it behave like the other titles: static text that renames in place on double-click, commit on blur/Enter, discard on Escape.

InlineTitleEditor stays the existing input (CRM headers). Pencil is gone; autofocus / onExit let a caller mount it on a gesture and tear it down on blur. StaticSplitLabel composes that with the same static span as the non-rename title — no RenamableSplitTitle.

Touch, which has no double-click, keeps a single tap. Renames still go through agentHarnessServiceClient.rename and handleAgentSessionRenamed.

Testing

Manual pass against the local stack on a real agent session: hover shows no pencil, single click leaves the title alone, double-click edits, Enter commits, Escape reverts, and the name survives a reload.

…pencil

The agent session header was the only title in the app with a hover pencil
and an always-focusable input, so a single click on the split tab dropped a
caret in the name. Match the rest of the app: a static title that renames in
place on double-click, plus a Rename item in the title menu for touch, where
double-click doesn't exist.

Removing the pencil also aligns the CRM contact and company headers with the
markdown document title the shared editor's docs already claim to mirror.

Kobalte traps focus inside an open menu, so the editor the Rename item
mounted never took focus and the item looked inert. Touch has no
double-click, so the title takes a single tap there — which is what the
always-focusable input did before this change.

Summary by CodeRabbit

  • New Features

    • Split titles can now be renamed inline by double-clicking, or by single-tapping on touch devices.
    • Press Enter or click away to save a new title; press Escape to cancel.
    • The editor automatically focuses and selects the existing title when opened.
  • Bug Fixes

    • Editing interactions no longer trigger the surrounding split title controls.
    • Blank or unchanged titles are not saved.
  • Tests

    • Added coverage for title editing, cancellation, focus behavior, and touch interactions.

Walkthrough

Adds autofocus and exit callbacks to InlineTitleEditor and removes its pencil button. Adds RenamableSplitTitle for double-click and touch-tap renaming. Updates SplitLabel to use the new component. Adds tests for editor lifecycle, rename commits, cancellation, validation, focus behavior, and device-specific gestures.

Merge Risk: 🔵 Low · up to a2050

The title now enters edit mode through pointer or touch gestures, but keyboard-only users cannot start renaming and double-clicking the active editor may also open the split context menu. This is a bounded UI risk; the PR is mergeable with explicit follow-up to address those interaction issues.

Add keyboard activation to the static title.

The interactive <span> is not focusable and has no keyboard handler. Keyboard-only users cannot enter edit mode. Use a semantic button, or add focus, keyboard activation, and an accessible name. Add an Enter and Space regression test.

Stop dblclick propagation from the editor.

This wrapper stops each click, but it does not stop dblclick. When split title actions exist, a double-click in the input bubbles to SplitLabelContextMenu and opens the context menu. Stop propagation for onDblClick on this wrapper. Add a regression test for double-clicking the active editor.

The split header already had InlineTitleEditor. Own the static-title /
double-click swap in StaticSplitLabel instead of a one-off wrapper, and
drop the extra test files.
