 ## [Unreleased]
 
+### Fixed

+- **TUI prompt symbol changes based on input mode** (#6431): The
+  ``PromptInput`` widget now displays a dynamic mode-dependent symbol at the
+  bottom of the TUI prompt area: ``">"`` for normal mode (plain/text with
+  @references), ``"/"`` for slash-command mode (input starts with ``/``), and
+  ``"$"`` for shell mode (input starts with ``!`` or ``$``). This matches the
+  specification (lines 29304-29311, 29085, 29493) and gives users immediate
+  visual feedback about which input mode they are in. The ``_detect_mode_symbol()``
+  helper performs the first-character classification, and Textual event hooks
+  (``on_input_changed`` / ``input_changed``) trigger live updates as the user
+  types. CSS modifier classes ``mode-normal``, ``mode-command``, and ``mode-shell``
+  are applied dynamically so the TUI stylesheet can render distinct visual cues
+  per mode (accented border colors for command and shell). The ``consume_text()``
+  method now strips the leading mode-symbol prefix from submitted text so
+  downstream code receives clean input without shell/command markers. Added BDD
+  scenario suite in ``features/tui_prompt_mode_symbols.feature`` with corresponding
+  step definitions in
+  ``features/steps/tui_prompt_mode_symbols_steps.py``.

 - Fixed `ReactiveEventBus.emit()` exception handler to log the full exception
   message (`str(exc)`) and enable traceback forwarding (`exc_info=True`).
   Previously the handler logged only the exception type name (e.g.

CONTRIBUTORS.md

@@ -33,4 +33,5 @@ Below are some of the specific details of various contributions.
 * HAL 9000 has contributed the LLMTraceRepository data-integrity fix (PR #8185 / issue #7505): replaced the unconditional `session.commit()` in `LLMTraceRepository.save()` with a dual-path implementation that respects the UnitOfWork pattern — flushing only when an external session is provided, and flushing + committing + closing when operating standalone. This eliminates premature transaction commits, loss of rollback capability, and a docstring/implementation mismatch.
 * HAL 9000 has contributed the ACMS Index Data Model and File Traversal Engine (PR #9664 / issue #9579): foundational data structures for indexed context entries with hot/warm/cold/archive storage tier classification, tag system, and a timeout-safe chunked file traversal engine for large projects with 10,000+ files.
 
-* HAL 9000 has contributed the error-suppression removal fix (PR #9247 / issue #9060): removed both `try...except Exception:` blocks in `register_registry_agents()` that silently suppressed errors from `actor_registry.list_actors()` and the route bridge refresh, enabling exceptions to propagate per CONTRIBUTING.md fail-fast policy. Added three Behave scenarios verifying RuntimeError, AttributeError, and TypeError propagation.

Added BDD test suite in `features/tui_prompt_mode_symbols.feature`.
