 - All file paths are relative to the worktree root (e.g. `server/src/bridge/types.rs`).
 - Do not navigate to or access sibling worktrees (`../client/`, `../copy/`, etc.) unless explicitly instructed.
 - **Exception — stale git lock files:** Worktree index locks live in the shared `.git` directory (e.g. `main/.git/worktrees/copy/index.lock`). If a `git` command fails with `index.lock: File exists`, you may remove the lock file for **your own worktree only**. Never touch lock files belonging to other worktrees.
+- **Never chain git commands** in a single Bash call (e.g. `git add ... && git commit ...`). The shared `.git` directory means concurrent index access from the same terminal creates `index.lock` collisions. Always run `git add` and `git commit` as **separate sequential Bash calls**.

Subject: [PATCH 2/5] feat(client): character select, triangle activation
 consumer, news ticker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sprint 24 Signal — three client tickets delivering the player-facing
storyteller feedback loop:

- #588: Character archetype select screen between New Game and session
  start. Two-card UI (Smuggler/Detective), keyboard+mouse, ESC cancels.
  GameState.character_archetype persisted and sent in StartupMessage.
  PROTOCOL_VERSION bumped to 19.
- #590: Triangle crisis event consumer. Decodes triangle_crisis_events
  from snapshot, fires sfx_monologue_chime_urgent once per triangle per
  session via AudioManager.CHIME_ACTIVATION.
- #592: News ticker HUD element. Scrolling marquee on UILayer, visible
  only when current_ticker is present in snapshot (Last Shift zone).
  Zero-arg update_from_state reads from GameState.current_snapshot.

 ## [Unreleased]
 
 ### Added
+- Character archetype select screen — two-card UI (Smuggler/Detective) between New Game and session start, keyboard+mouse selection, ESC cancels (#588, D-027)
+- Triangle activation consumer — urgent monologue chime fires once per triangle per session when triangle_crisis_events received (#590, D-039)
+- News ticker HUD — scrolling marquee visible in The Last Shift zone, hidden elsewhere, reads current_ticker from snapshot (#592, D-039)
 - Triangle activation proximity monologue lines — 5 smuggler lines (Kael Davan) and 5 detective lines (Sera Venn/Torek Lintar) that fire when observing triangle anchor NPCs post-activation (#597, D-035, D-039)
 
+### Changed
+- Protocol version bumped to 19 — StartupMessage includes character_archetype, snapshot includes triangle_crisis_events and current_ticker (#588, #590, #592)
+
 ## [v0.1.23] — 2026-03-04

- protocol.gd: replace capitalize() with explicit match for archetype
  string mapping, push_error on unknown input with Detective fallback
- main.gd: clear _known_triangle_ids in _teleport_transition() alongside
  _known_recognition_ids so chime re-fires after room change
- news_ticker.gd: defer get_minimum_size() via call_deferred to run
  after layout pass, fixing first-frame scroll distance
- 3 new tests: unknown archetype fallback, triangle dedup per-id,
  independent triangle ID firing
