+## Main branch workflow (sprint close + version bump)
+
+When `/start-sprint` is run on `main`, it means the user wants to close
+the current sprint, cut a version, and prepare for the next one.
+
+### M1. Close the active sprint
+
+```bash
+db/connectors/sprint stop
+```
+
+This marks the active sprint as completed and lists carry-over candidates.
+Note the sprint number (N) from the output.
+
+### M2. Bump the version
+
+The project version scheme is `v0.1.{sprint_number}`. After closing
+sprint N, the version is `v0.1.N`.
+
+Update `CHANGELOG.md`:
+- Move all entries under `## [Unreleased]` into a new section
+  `## [v0.1.N] — YYYY-MM-DD` (using today's date).
+- Leave `## [Unreleased]` as an empty section above the new version.
+- Keep the existing sub-headings (Added, Fixed, Changed, Removed) —
+  only move entries that have content.
+
+### M3. Commit the release
+
+Stage and commit `CHANGELOG.md`:
+```
+chore(meta): release v0.1.N
+```
+
+### M4. Tag the release
+
+```bash
+git tag v0.1.N
+```
+
+### M5. Push
+
+```bash
+git push && git push --tags
+```
+
+### M6. Report
+
+Output a summary:
+- Sprint closed (name, done/total tickets, carry-over count)
+- Version tagged (`v0.1.N`)
+- Carry-over candidates (if any)
+- Suggest running `/plan-sprint` next to prepare the next sprint

 ## [Unreleased]

+## [v0.1.9] — 2026-02-18
+
+### Fixed
+- `make game` now builds client before launching — was missing `build-client` dependency, causing class_name registration failures after `make clean`
+- `build-client` uses `--import --quit` instead of just `--quit` — ensures `.godot/` cache and `global_script_class_cache.cfg` are created from scratch
+- `make clean` preserves `client/.godot/` directory (clears contents only) to avoid Godot startup issues
+
+### Added
+- `--description TEXT` flag for `ticket create` CLI — previously required raw SQL workaround to set ticket descriptions
+
+### Changed
+- UI audio assets revised — monologue chimes re-generated (0.8s, insert-tech aesthetic), fog_recognition re-generated (was silent), all 8 assets normalized to 44.1kHz stereo LUFS -16 (#453)
+- review-pr skill: explicit verdict rules — critical/warning → REQUEST_CHANGES, suggestion-only → APPROVE
+
+### Added
+- `make golden-diff` + `make golden-update` targets (#486) — developer workflow for golden file comparison and regeneration; safe restore on cargo failure
+- Gauntlet checklist YAML schema (#497) — 7 condition types evaluable from ObserverSnapshot, per-room checklists for 3 rooms, `make checklist-validate` and `make checklist-generate` targets, wired into `pre-pr-content` gate
+- Gauntlet room timer + personal bests (#496) — GauntletHUD shows TIMER: MM:SS (PB: MM:SS), starts on room entry, resets on room change, persists stats to user://dev/gauntlet-stats.json, session summary on disconnect, hidden in non-gauntlet mode
+- WRONG button F12 MVP (#495) — bug report capture: pause sim, show modal prompt, save snapshot.json + render.txt + description.txt to user://bug-reports/, Esc to cancel
+- GameState.room_id and gauntlet_mode fields — parsed from ObserverSnapshot, enabling gauntlet UI
+- BUG_REPORT action in InputMapper (F12 binding) with SimBridge wire guard (client-only)
+- 24 new anti-tedium tests — GauntletHUD lifecycle (16: timer, PB, visibility, room change, session tracking) + BugReportDialog (8: pause/unpause, wire guard, text render, edge cases)
+- whatsinagame starter kit — reusable multi-agent team bootstrap for any project (3-tier profiles, 18 skills, 16 agent archetypes, stakeholder personas, ticketing DB, decision tracking)
+- Domain-action naming convention for skills documented in create-skill guide
+- `gauntlet` feature flag (default-on) — allows stripping Gauntlet test world from release builds with `--no-default-features`
+- `EXPECTED_ENTITY_COUNT` and `RESET_PLATE_STABLE_IDS` constants — entity counts derived from StableId ranges instead of hardcoded values
+- Debounce exact-boundary test for room reset (tick 9 rejected, tick 10 accepted)
+- Reset plate StableId verification in `stable_id_ranges_match_spec`
+- Runtime content test (`content_runtime.rs`) separated from structural loading tests
+- Client P2 tests (#492) — 16 gdUnit4 tests for camera (smoothing, zoom, viewport, follow, no-pan), entity alpha/color (peripheral, forward, NPC color, player constant), UI (monologue, interaction, inventory, dialogue, pause, fog blob, fog z_index)
+- Client P3 tests (#493) — 12 gdUnit4 tests for z-layer ordering (floor/ysort/fog/UI), entity lerp (snap, converge, LERP_SPEED=12.0), Tyre additions (recognition, facing, delta scaling, blob removal)
+- Anti-tedium regression tests (#494) — 5 tests: F12 no-crash guard, no queued input, gauntlet UI hidden in default/normal snapshot/multi-tick modes
+
+### Changed
+- Room reset API consolidated to `plan_reset` only — `execute_reset` removed (was a maintenance trap; production uses Commands via `plan_reset`)
+- `room_at()` documented with z-range and corridor overlap assumptions
+- TCP runtime test now has 10s read timeout and registers player in EntityRegistry
+
+### Removed
+- Dead `RoomMember` component from reset.rs (defined but never used)
+- Protocol v8: dialogue_response field decoding (DialogueResponseEvent with line_id, text, speaker_entity_id) from server #305/D-028
+- Test client binary scaffolding (#480) — standalone crate at `tooling/test-client/` with CLI (--connect, --replay, --text, --json, --quiet, --golden, --ticks), exit codes (0/1/2), golden file JSON diff, JSONL replay loader
+- Snapshot text renderer (#481) — `format_snapshot_text(&ObserverSnapshot)` pub-exported from server crate, entity labels as kind:entity_id sorted by distance, room name stub, 10 unit tests
+- Sprint 9 (Gauntlet) briefing files — server, client, CI, audio, joint — 23 tickets across 4 teams
+- Weapon aim lock audio (`sfx_weapon_aim_lock.ogg`) — clinical targeting confirmation tone for weapon aim state (#440)
+- Stance change audio (`sfx_stance_change.ogg`) — subtle mechanical click for stance toggle feedback (#440)
+
+### Fixed
+- MessagePack int_64 encoder dead code branch (#516) — `-(1 << 63)` overflowed making int_64 branch unreachable; negative values beyond int_32 now correctly encode as 0xd3 instead of 0xcf
+- Cross-encoder fixture pipeline hardened — encode failures now exit non-zero instead of writing empty .msgpack files (#475 review)
+- GDScript fixture test no longer silently skips on missing/empty fixture dir — asserts instead (#475 review)
+- GDScript fixture generator covers all PlayerAction variants (added MoveSouth, MoveEast, MoveWest, Unpause, ToggleStanceDown, WalkAway)
+- `make pre-pr` now checks GDScript fixture staleness alongside Rust fixtures
+- Protocol version bumped from 7 to 8 to match server — fixes 5 test failures from version mismatch
+- Interact action encoding changed from unit variant to struct variant to match server's PlayerAction::Interact { target_entity_id, verb }
+- Monologue duplication test (test_monologue_not_duplicated_after_consumption) fixed — was using poll_snapshot() which doesn't consume _last_snapshot in test mode
+- `make pre-pr` target — full pre-PR verification chain: lint → build → test → content validation → fixture staleness (#460, #465)
+- Branch-specific pre-PR variants: `make pre-pr-server`, `make pre-pr-client`, `make pre-pr-content`
+- Content cross-reference validation (9 checks) — canonical_id uniqueness, relationship targets, location slugs, dialogue locations, fact_ids, triangle membership, npc_count, dialogue line_ids, bidirectional relationships (#464)
+
+### Fixed
+- Dialogue schema missing `focused` (mood) and `greeting` (situation) values added in Sprint 7-8 content
+- Speaker wire ID silent fallback — dialogue now warns and skips when target entity missing from registry (was silently using 0)
+- Cross-plugin system ordering — trigger_recognition_monologue now runs after detect_anomalies (latent determinism bug)
+- Walk-away ordering — process_walk_away now runs after process_talk_interaction (prevents same-tick race)
+- ActiveDialogue overwrite — new Talk while in existing dialogue now emits IncompleteInteraction before replacing
+- Server-side Talk range check — handle_talk now enforces CLOSE_RANGE before setting TalkRequest (was client-only)
+- ExamineNpc label collision — VerbKind::ExamineNpc now uses "Examine NPC" label (was "Observe", same as generic Observe)
+- Dead conditional in main.rs collapsed (both branches were identical)
+- WalkAway variant added to all_player_action_variants_roundtrip serialization test
+
+### Changed
+- DialogueCooldownTracker.used changed from Vec to BTreeMap for O(log n) lookup (D-041 compliance)
+- MonologueState.shown_ids changed from Vec to HashSet for O(1) contains check (was O(n) per tick)
+- Secret trust tier documented as unreachable with TODO for Phase 2 KG-gated unlock
+
+### Added
+- Determinism test: different_seed_produces_different_replay — exercises SimRng via dialogue weighted selection
+- Dialogue selection pipeline (#305, D-028) — 4-layer filtering engine: access tier from KG relationship, situation derivation from game state, trust tier, weighted topic+mood scoring via SimRng. Full Talk verb → selected line → ObserverSnapshot pipeline with cooldown tracking
+- ContentSlug component (#452) — stable content identity from YAML (e.g. "kael-davan") independent of runtime Entity handles, for knowledge graph interaction memory across save/load
+- Walk-away KG recording (#427, D-064) — IncompleteInteraction knowledge events with Talk/Confront type, ActiveDialogue tracking, walk-away detection clears dialogue and records in KG
+- Anomaly detection for urgent recognition (#450, D-060) — AnomalyMarker flags PersonOfInterest/Contradicted entities for 0.3s cognitive delay instead of 0.6s normal
+- Recognition monologue during cognitive delay (#451, D-060) — monologue fires at delay START (grey blob phase), not completion. v0.1 fallback lines, anomaly prioritization, cooldown tracking
+- Server --test-mode, --port, --seed CLI flags (#459) — LISTENING:{port} stdout signal, OS-assigned ports, deterministic seed override, stderr-only tracing
+- Determinism gauntlet test (#466) — 20-tick replay determinism regression test with movement, stance, pause/unpause exercise
+- Pause guard test suite (#461-463, #468) — 7 tests covering movement, unpause, roundtrip, stance, interact, batch, tick_rate during pause
+- EntityRegistry lifecycle tests (#469) — stale mapping, re-register, unknown unregister edge cases
+- Boundary value encode/roundtrip tests (#471) — 41 values across all MessagePack integer format boundaries
+- Encoding asymmetry tests (#473) — Rust decoder accepts GDScript-style signed encodings for unsigned fields
+- Boundary fixture generation (#472) — 14 raw + 5 snapshot fixtures at integer format boundaries
+- Malformed batch rejection test (#479) — truncated, garbage, and mixed payloads rejected atomically
+- Per-fix determinism unit tests (#467) — equidistant NPC ordering, visible tile sorting, same-tile mover resolution
+
+### Fixed
+- Determinism: visible_ids HashSet → BTreeSet for stable iteration order (#456)
+- Determinism: visible entities in snapshot sorted by entity_id (#457)
+- Determinism: movers sorted by Entity bits in validate_movement (#458)
+- Pause guard blocks all actions except Pause/Unpause while paused (previously only blocked movement)
+
+### Changed
+- Protocol version bumped from v7 to v8 (dialogue_response field in ObserverSnapshot)
+
 ### Added
 - AudioManager autoload (#255, D-068/D-069/D-073) — 5-bus architecture (Music, Ambient, WorldSFX, PlayerActions, UISounds), directory-scan asset registry, spatial/non-spatial playback, audio dip profiles (dialogue, confrontation, listening_focus) with low-pass filter sweep, zone crossfade stub
 - Dialogue response selection (#435, D-061/D-062) — structured options with response_id, priority sorting, max 3 visible, invisible locked options, RichTextLabel for BBCode support

+## Anti-tedium regression tests (#494):
+## Guard against UI clutter that makes testing tedious.
+##
+## Test 1: F12 bug report capture — pressing F12 must not crash; when #495 lands,
+##         the handler should pause, show capture dialog, save 3 files, unpause.
+## Test 2: Gauntlet progress UI hidden — in non-Gauntlet mode (no room_id or
+##         gauntlet_mode flag in snapshot), timer and personal-bests must not appear.
+##
+## #495 blocked by #481/#490 (server). #496 blocked by #487 (server).
+## Tests stub blocked features and verify anti-tedium guards.
+## Spec ref: Sprint 9 briefing (client.md), #495, #496.
