This PR groups the TUI fixes that restore macOS Terminal usability and clean up the theme/composer regressions:
- copy transcript selections on macOS drag-release so Terminal.app users can copy while mouse tracking is enabled
- copy composer selections on macOS drag-release; composer selection is internal to TextInput and does not use the global Ink selection bus
- keep IDE Cmd+C forwarding setup macOS-only, and make keybinding conflict checks respect simple when-clause overlap/negation
- force truecolor before chalk initializes (unless NO_COLOR / FORCE_COLOR / HERMES_TUI_TRUECOLOR opt-outs apply) so the default banner keeps its gold/amber/bronze gradient in Terminal.app
- move TUI surfaces onto semantic theme tokens and preserve skin prompt symbols as bare tokens with renderer-owned spacing
- render focused placeholders as dim hint text in TTY mode instead of inverse/selected-looking synthetic cursor text
Selected rows in the model/session/skills pickers and approval/clarify
prompts only changed from dim gray to cornsilk, which reads as low
contrast on lighter themes and LCDs (reported during TUI v2 blitz).
Switch the selected row to `inverse bold` with the brand accent color
across modelPicker, sessionPicker, skillsHub, and prompts so the
highlight is terminal-portable and unambiguous. Unselected rows stay
dim. Also extends the sessionPicker middle meta column (which was
always dim) to inherit the row's selection state.
Medium fixes:
- textInput.tsx: prevent silent data loss when async paste resolves
after user types — fall back to raw text insert at current cursor
instead of dropping the content entirely
- useComposerState.ts: tighten looksLikeDroppedPath to require a
second '/' or '.' for bare absolute paths, avoiding unnecessary
RPC round-trips for pasted text like /api or /help
- useComposerState.ts: add cross-reference comment linking to the
canonical _detect_file_drop() in cli.py
- osc52.ts: add 500ms timeout via Promise.race so terminals that
do not support OSC52 clipboard queries cannot hang paste
Low fixes:
- terminalSetup.ts: export isRemoteShellSession and reuse in
terminalParity.ts and useComposerState.ts (was inlined 3 times)
- useComposerState.ts: extract insertAtCursor helper, replacing 3
copies of the lead/tail spacing logic
- useComposerState.ts: remove redundant gw from handleTextPaste
useCallback dependency array
- terminalSetup.test.ts: add EACCES (read-only keybindings.json)
and unterminated block comment test coverage
Fixes from OutThisLife review:
1. Restore Linux Alt+Enter newline: textInput.tsx now uses
k.shift || (isMac ? isActionMod(k) : k.meta) so Alt+Enter
inserts a newline on Linux (was broken by isMac guard).
2. Fix image.attach response type: useComposerState.ts now uses
ImageAttachResponse (which already has remainder) instead of
InputDetectDropResponse with intersection.
3. Expand looksLikeDroppedPath test coverage with edge cases for
image extensions, file:// URIs, spaces, empty input, and
non-file URLs.
4. Make terminalParity.test.ts hermetic: terminalParityHints() now
accepts optional fileOps/homeDir and passes them through to
shouldPromptForTerminalSetup(), so tests inject mock readFile
instead of hitting the real filesystem.
Fixes from Copilot inline review:
5. Remove unused options.now parameter from configureTerminalKeybindings.
6. Replace naive stripJsonComments (full-line // only) with a proper
JSONC stripper that handles inline // comments, block comments,
trailing commas, and preserves comment-like sequences in strings.
7. Move backupFile() call from immediately after read to right before
write - backups are only created when changes will actually be
written, not on every /terminal-setup invocation.
