Branch: fix/tui-permissions-screen-wrong-base-class
Commit Message: fix(tui): convert PermissionsScreen from Static widget to proper Textual Screen subclass
Milestone: v3.7.0
Parent Epic: #868

Bug Report

What Was Tested

Source code inspection of src/cleveragents/tui/permissions/screen.py.

Expected Behavior (from spec)

Per the specification (§TUI > Screens), PermissionsScreen must be a proper Textual Screen subclass (i.e., inherit from textual.app.Screen). This allows it to be pushed onto the screen stack via app.push_screen(), receive keyboard events natively, and participate in the Textual screen lifecycle (compose, on_mount, dismiss, etc.).

Actual Behavior

PermissionsScreen in src/cleveragents/tui/permissions/screen.py inherits from _StaticBase, which resolves to textual.widgets.Static. This is a widget, not a screen. Specifically:

# permissions/screen.py
def _load_static_base() -> type[Any]:
    try:
        return importlib.import_module("textual.widgets").Static
    except Exception:
        ...

_StaticBase = _load_static_base()

class PermissionsScreen(_StaticBase):  # ← inherits from Static, NOT Screen
    ...

As a Static widget, PermissionsScreen:

Cannot be pushed onto the screen stack via app.push_screen()
Cannot receive keyboard events natively (no BINDINGS class variable support)
Cannot use self.dismiss() to return a result to the caller
Cannot participate in the Textual screen lifecycle properly

The keyboard bindings documented in the class docstring (a, A, r, R, j, k, d, escape) are not wired to any Textual action methods — they are just documentation with no functional implementation.

Steps to Reproduce

Inspect src/cleveragents/tui/permissions/screen.py — PermissionsScreen inherits from _StaticBase (which is textual.widgets.Static).
Attempt to use app.push_screen(PermissionsScreen(...)) — this will fail because Static is not a Screen.
Press a, r, j, k, d keys while PermissionsScreen is displayed — no keyboard events are handled.

Impact

PermissionsScreen cannot be used as a proper TUI screen for permission request handling.
Keyboard shortcuts for allow/reject/navigate/diff-cycle are non-functional.
The permission request workflow is broken — users cannot interactively approve or reject tool permission requests via the TUI.

Subtasks

Refactor PermissionsScreen to inherit from textual.app.Screen instead of textual.widgets.Static
Add BINDINGS class variable with a (allow-once), A (allow-always), r (reject-once), R (reject-always), j (nav-next), k (nav-prev), d (cycle-diff), escape (dismiss)
Implement action methods: action_allow_once(), action_allow_always(), action_reject_once(), action_reject_always(), action_nav_next(), action_nav_prev(), action_cycle_diff(), action_dismiss()
Implement compose() method to render the split-pane layout (file list + diff view)
Update permissions/__init__.py exports accordingly
Tests (Behave): Add TDD scenario tagged @tdd_issue, @tdd_expected_fail asserting PermissionsScreen is a textual.app.Screen subclass
Tests (Behave): Add TDD scenario asserting keyboard bindings are functional
Remove @tdd_expected_fail once implemented and verify scenarios pass
Verify coverage >= 97% via nox -s coverage_report
Run nox (all default sessions), fix any errors

Definition of Done

PermissionsScreen inherits from textual.app.Screen (not Static)
issubclass(PermissionsScreen, Screen) returns True
Keyboard bindings a, A, r, R, j, k, d, escape are functional
app.push_screen(PermissionsScreen(...)) works correctly
TDD scenarios pass without @tdd_expected_fail
All nox stages pass
Coverage >= 97%
A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details about the implementation.
The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.

This allows it to be pushed onto the screen stack via `app.push_screen()`, receive keyboard events natively, and participate in the Textual screen lifecycle (compose, on_mount, dismiss, etc.). ### Actual Behavior `PermissionsScreen` in `src/cleveragents/tui/permissions/screen.py` inherits from `_StaticBase`, which resolves to `textual.widgets.Static`. This is a **widget**, not a **screen**. Specifically: ```python # permissions/screen.py def _load_static_base() -> type[Any]: try: return importlib.import_module("textual.widgets").Static except Exception: ... _StaticBase = _load_static_base() class PermissionsScreen(_StaticBase): # ← inherits from Static, NOT Screen ... ``` As a `Static` widget, `PermissionsScreen`: - Cannot be pushed onto the screen stack via `app.push_screen()` - Cannot receive keyboard events natively (no `BINDINGS` class variable support) - Cannot use `self.dismiss()` to return a result to the caller - Cannot participate in the Textual screen lifecycle properly The keyboard bindings documented in the class docstring (`a`, `A`, `r`, `R`, `j`, `k`, `d`, `escape`) are not wired to any Textual action methods — they are just documentation with no functional implementation. ### Steps to Reproduce 1. Inspect `src/cleveragents/tui/permissions/screen.py` — `PermissionsScreen` inherits from `_StaticBase` (which is `textual.widgets.Static`). 2.

Implementation Attempt — Tier 3: Sonnet — Success

Implemented the fix for PermissionsScreen inheriting from Static widget instead of Textual Screen.

Changes made:

src/cleveragents/tui/permissions/screen.py: Changed PermissionsScreen to inherit from textual.app.Screen instead of textual.widgets.Static. Replaced _load_static_base() with _load_screen_base(). Added BINDINGS class variable with 8 keyboard shortcuts (a, A, r, R, j, k, d, escape). Implemented 8 action methods (action_allow_once, action_allow_always, action_reject_once, action_reject_always, action_nav_next, action_nav_prev, action_cycle_diff, action_dismiss_screen). Added compose() method for Textual screen layout. Added update() method for backward compatibility.
features/tui_permissions_screen.feature: Added 3 new TDD scenarios tagged @tdd_issue @tdd_issue_10488 (without @tdd_expected_fail since the fix is implemented).
features/steps/tui_permissions_screen_steps.py: Added step definitions for the new TDD scenarios.

Quality gate status: lint ✓, typecheck ✓, unit_tests ✓ (65 scenarios passing)
