- Debug console server — 10 DebugCommandKind variants (AdvanceTicks, SkipToContamination, TeleportToPosition, InspectNpc, ListTriangles, etc.) with DebugResponsePayload on ObserverSnapshot (#580)
- Debug console client — tilde-toggle UI panel with command input, output log, settings toggle, and full DebugCommandKind dispatch via protocol v18 (#581)
- Entity-bound dialogue speaker colors — NPC colors assigned by entity ID (not screen position) with per-conversation lifecycle and round-robin palette (#573)
- Sova Transit District tile maps — 5 locations authored: The Terminal (44×28), The Last Shift (34×22), Maintenance Corridors (58×6), Gate Ground (40×34), Gate Gallery (32×10) (#582, #583)

### Fixed
- LOS boundary walls — 1-tile wall margin beyond vision cone included in visible_tiles as BoundaryWall sector, walls at fog edge now render instead of bleeding into fog (#584)
- LOS boundary walls client — BoundaryWall tiles render through fog without marking explored, 4 new fog tests verify lifecycle (#585)
- Entity renderer test failures — updated 7 stale ColorRect/position assertions for Sprite2D migration, fixed SoundIndicatorRenderer class cache (#574)
- Dialogue speaker color contrast — re-enforce contrast floor after desaturation for passive (overheard) lines
- PROTOCOL_VERSION 17 → 18 mismatch — client rejected every server snapshot
- Debug console D-088 pause — sim now pauses while console is open, matching dialogue/settings overlay behavior
- Debug console settings toggle reads live state instead of ConfigFile, preventing checkbox divergence

### Changed
- PROTOCOL_VERSION bumped 17 → 18 (debug_response field on ObserverSnapshot, DebugCommand PlayerAction variant)

## [v0.1.22] — 2026-03-03

### Added
- Visual test harness — `make screenshot`, `make test-visual`, `make visual-update` for automated visual regression testing with golden PNGs across 11 scenarios (fog, HUD, dialogue, minimap)
- Visual movie mode — `make visual-movie` captures interaction flows as frame sequences with contact sheet generation
- World seed protocol — StartupMessage carries world_seed from client to server after handshake, enabling deterministic NPC population seeding (D-010, D-029)
- EntanglementConfig — per-seed NPC population ratios (flat/mundane/intrigue) sampled from seeded RNG with D-029 bounds, ensuring same seed = same world (#175, #178)
- Fog debug mode — toggle FogState.debug_exploration to render raw exploration texture as colored overlay for diagnostic use
- D-110 through D-112: z-level addressing, subterranean architecture, no instancing decisions
- Q-051: speech bubble indicator over speaking NPCs
- Sprint 22 "Wire" briefings (server, client, visual, CI, planning, joint)

### Added (server)
- Production NPC pool generation — 23 authored Sova NPCs spawn with EntanglementTag (Flat/Intrigue) based on triangle membership (#176, D-029)
- Authored triangle instantiation — 5 Sova triangles (3 active forks, 2 passive tensions) loaded from content YAML with deterministic IDs (#188, D-087)
- Contamination activation mechanic — timer-based storyteller fires after 30 game-minutes, pressures active triangles, emits ContaminationEvent (#254)
- Modifications data model stub — Vec<Modification> on chunk entities, round-trips through save/load for future construction DLC (#567, D-112)
- Zone Gate gauntlet room — two-zone test room with door boundary, zone crossing detection system (#512)
- Fuzzy map tests — 50-seed randomized testing of procedural maps against 4 structural invariants (#509)

### Fixed
- Fog shader: silent compilation failure in OpenGL3 compat mode — removed `return` statements from fragment() which are not supported, causing fog overlay to render as no-op (root cause of Sprint 22 fog regression)
- Fog system: blocky stair-stepped edges at vision cone boundary — doubled Gaussian blur step size for D-066 compliant 6-8 tile smooth gradient (#569)
- Fog system: zero visibility in explored areas — switched bounds calculation from visible_tiles (empty in live server mode) to visible_positions, and removed shader guard that cut off gradient bleed into unexplored tiles (#569)
- Fog shader alpha tuned to D-059 spec: light fog 0.25-0.35 (was 0.25-0.55), deep fog 0.55-0.70 (was 0.78-0.90) — world content now visible through fog instead of hidden behind it (#563)

### Changed
- Fog shader now distinguishes light fog (near cone, neutral dark) from deep fog (far from cone, zone temperature tint) with separate Perlin noise breathing cycles (8-10s / 15-20s)
- Zone temperature tint populated per-tile from server zone_id: bar=warm amber-dark, hub=cool blue-dark, corridor=neutral dark (D-059/D-046/D-077)
- Simplified vision cone from 3-sector (forward/peripheral/blind) to forward-only 120° arc — server sends only forward-cone tiles, client renders explored tiles behind the player with light fog overlay
- Simplified fog shader from 5-layer to 3-layer model (clear, explored, unexplored)
- Fog texture resize now preserves exploration data — tiles behind the player stay as light fog instead of reverting to unexplored black
- Updated D-015/D-017 perception decisions to reflect simplified cone model
- Moved connector scripts from db/connectors/ to tooling/db/ (#274) — backwards-compat symlink removed in #568

### Removed
- db/connectors symlink — all references now use tooling/db/ directly (#568)

## [v0.1.20] — 2026-02-25

- D-094: Spatial hierarchy — chunk (64×64 sim) → block (128×128 sim) → district (4×4 blocks, 256×256 visual), supersedes D-014 estimate
- D-095: Horizon stations and transport lore — span gates (human-built, dual-use), horizon stations (alien-built, 4-8 apertures), "The Ring" per-system naming, sequential hop travel, The Loop internal tram

- SnapshotEventRouter — callable-based snapshot dispatch replaces inline if-has blocks in main.gd (#559)
- YamlParser shared utility — unified YAML parsing for UI strings and checklist conditions (#560)

### Fixed
- Wire triangle crisis event queue into observer snapshot — clients now receive TriangleCrisisEventWire via protocol v16 (was always empty)
- Persist TriangleState in SaveStateV1 — triangle phase and tension survive save/load cycles
- Validate dangling with_role references in TriangleDef constraint validation
- Replace O(n²) fallback NPC assignment with BTreeSet; prevent same NPC assigned to two roles in one triangle
- Replace O(N*M) scan in apply_resolve_triangle with BTreeMap index for O(1) per-command lookup
- Add From impls for RoleId, TriangleId, StableId, TriangleCrisisEventWire — eliminate fragile .0 newtype access
- Consolidate near-identical unit tests with integration counterparts

### Changed
- Sova station profile updated — horizon gates located at The Van Maanen Ring (800 AU), not on Station Sova; Admin Hub houses transit processing facility only
- game_state.gd: stationary_ticks and zone_id now read from server snapshot with deprecated client-side fallbacks (#557, D-020)
- dialogue_box.gd: decoupled from GameState and AudioManager via signals — zero direct autoload references (#558, D-020)
- main.gd: snapshot dispatch via SnapshotEventRouter, dialogue signal coordinator handlers (#559, #558)
- ui_strings.gd and checklist_evaluator.gd: delegate to YamlParser, ~140 lines of duplication removed (#560)

## [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

- 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)

- 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)

- 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)

- 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

- 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

- 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

- Workshop skill updated — agents now write output files to disk instead of sending messages, fixing documenter access
- Camera anchor test suite — 10 gdUnit4 tests verifying camera init, smoothing cycle, and player tracking

### Fixed
- Server never sends snapshots — blocking TCP read in receive_bridge_inputs stalled the entire bevy Update schedule; switched to non-blocking I/O with WouldBlock handling
- Camera doesn't center on player at startup — Camera2D smoothed_camera_pos starts at (0,0); now disable smoothing during init, snap to player, re-enable after first anchored frame
- Player moves while game is paused — movement commands now discarded when TickRate is Paused (pause/unpause still process)
- Spacebar only pauses, doesn't toggle — added UNPAUSE action with toggle logic based on tick_rate state

- Monologue/dialogue lost on snapshot overwrite — one-shot events now carried forward when a newer snapshot replaces an unconsumed one
- Fog shader white screen on load failure — ColorRect defaults to transparent, shader load failure logged instead of crashing
- Fog desync during camera smooth pan — fog rect now tracks camera position instead of player position

### Changed
- Server game loop throttled to ~20 ticks/sec (50ms frames) — non-blocking TCP loop no longer spins; remaining frame budget available for NPC AI

- D-066: Dual-scale grid — 0.5m simulation tiles for stealth granularity, 1m visual tiles for proportional art (2x retina factor). All world geometry 2x2 sim tile minimum so cover/LOS maps 1:1 with visuals. Amends OQ-01.
- Sprint CLI (`db/connectors/sprint`) — unified sprint lifecycle management with 5 subcommands: status, start, stop, start-work, prepare. Auto-detects sprint from DB state and team from git branch. Guards prevent activating unplanned sprints.
- Shared permission settings in `.claude/settings.json` — git, ticket/sprint CLI, make, tea, and core skills pre-approved across all worktrees. Deny rules block destructive operations.
- Decisions D-053 through D-065 from Control & Interaction Workshop — formalized interaction verb system, contextual actions, NPC awareness model, and related design decisions
- Sprint 6 Touch briefings for server, client, copy, and joint teams
- Control & Interaction Workshop outputs — full workshop notes and outcomes
- Smuggler inventory item specs for transit district (#441)
- Start-workshop skill for multi-agent design workshops

### Fixed

- Plan-sprint skill now enforces worktree-relative paths in generated briefings
- Worktree-update skill now discovers branches dynamically via `git worktree list` instead of relying on hardcoded branch names — fixes missed branches like `planning`

### Changed
- Start-sprint and plan-sprint skills updated to use sprint CLI instead of manual multi-query workflows
- Permission syntax migrated from deprecated `:*` suffix to modern space-wildcard format across all worktrees
- Internal monologue trigger system (#414) — enter_location fires on first tick, time_idle fires after 100 ticks of no movement, 300-tick cooldown, dedup within session, random line selection from content pools via ChaCha20 RNG
- MonologueEvent in ObserverSnapshot v5 — current_monologue field carries id, text, and display duration across the IPC bridge
- Client monologue display wiring — protocol v5 decoding, GameState extraction, HUD display pass-through

### Fixed
- NPC spawn missing Interactable component (#413) — NPCs spawned from content and proof room now have Interactable, enabling E-prompt detection
- PlayerAction::Interact was a no-op (#415) — changed from unit to struct variant with target_entity_id and verb fields, server logs interaction data

### Changed
- Protocol version bumped from 4 to 5 (MonologueEvent field, Interact variant change)
- MessagePack fixtures regenerated for protocol v5

### Changed
- UIStrings YAML parser now handles arbitrary nesting depth and inline comments — adapts to copy team's restructured ui-strings.yaml with multi-level sections (relationship_states, health_values)
- HUD uses new YAML keys: `hud.perception_mode_prefix`, `hud.time_prefix`, `hud.health` (empty prefixes display values directly)
- Interaction prompt keybind hint ("E") hardcoded instead of loaded from YAML — keybinding is not copywriter text

### Added
- Pre-commit FactId validation hook (#393) — grep-based check validates fact_id references in content YAML against canonical knowledge catalogs; advisory mode when catalogs are stubs, enforcing mode when populated
- Pre-commit hook infrastructure — `.config/hooks/` with modular dispatcher, `make setup-hooks` target, `core.hooksPath` config for worktree-safe hook installation
- `make check-fact-ids` target for manual fact_id validation
- UIStrings autoload with YAML-based UI string loading (#409) — minimal YAML parser, `get_text()` lookup with fallback-to-key
- HUD and interaction prompt labels now loaded from `client/data/ui-strings.yaml` instead of hardcoded strings

- UI microcopy (#409) — 72 YAML strings for client integration: interaction verbs, relationship states, HUD labels, perception modes, notifications, knowledge panel, tutorial prompts
- Kael Davan FRIEND pack (#297) — 86 hand-authored lines across 3 locations, 5-phase relationship arc with contradiction scene, dual-lens notes
- Sera Venn FRIEND pack (#298) — 75 hand-authored lines at The Last Shift, trust-gated gossip, avoidance contradiction, contaminated trust arc
- PC-as-NPC content (#401) — 70 authored items enabling second-playthrough recognition (D-039 wow moment #4)

### Changed
- Moved ui-strings.yaml from content/campaigns/_meta/ to client/data/ for direct Godot client loading

### Fixed

- Entity ref format inconsistency — normalized underscore format to npc:hyphenated across ~15 monologue references
- Phase tag inconsistency between FRIEND packs — standardized to phase-N format, added missing phase-2 tags to Kael ring ops lines
- Detective monologue gap for Kael — added 7 observation lines (7 → 15 total), added mood tags and bar_evening situation to Kael bar content
- Hoshe QA briefing updated with integration test coverage priorities — test harnesses, dedicated client-server test map, edge case focus

- Live server mode (`make game`) — single command builds server, launches client with TCP connection, auto-kills server on exit; `make stop` helper for manual cleanup
- `SR_LIVE=1` environment variable switches SimBridge from test mode to real TCP server connection
- TileKind in wire protocol (#412) — server sends Floor/Wall/Door/Object per visible tile, client renders walls and floors in live mode
- Input roundtrip integration test (#411) — spawns real server, connects via TCP, validates full movement and interact pipeline
- Debug logging for received player inputs on server (visible with `RUST_LOG=debug`)

### Fixed
- Interaction prompt target+verb data now attached to Interact action in game loop (#405) — was TODO stub, server receives `{target_entity_id, verb}` payload
- Player entity detection uses `kind.variant == "Player"` instead of hardcoded `entity_id == 1` — fixes "player not found" warnings when connected to real server (which assigns different IDs)
- Movement keys now work in live mode — client was sending millisecond timestamps as input tick, server only processes ticks <= current frame counter; now uses server tick from latest snapshot
- Entity-to-tile alignment in live mode — server sends tile-center render coords (tile 16 → 16.5), entity renderer now floors to tile index before positioning

### Added
- Content loader Phase 2 (#408) — 2-phase spawn pipeline loads real YAML content into ECS entities: enums, entity attributes, pools, templates, triangles, NPC profiles with Want/Tolerance/Contentment/Personality/Tells/Skills axes plus cross-reference resolution for Secrets, Relationships, Information, and DailyRoutine

- YAML to RON converter tool (#403) — build-time converter in tooling/content-converter/, runs via `make content-ron`
- Line previewer CLI (#407) — 4 subcommands (dialogue, monologue, coverage, sequence) for content authors to test line selection without running the full game
- Happiness added to WantKind enum — Harek remapped from Safety to Happiness

### Fixed
- Dialogue-pool schema corrected to use arrays for situation/topic/mood per D-035 (were incorrectly single strings)
- NPC want.primary changed from narrative strings to WantKind enum keywords — fixes silent Want component drop at spawn time
- Schema enum constraint added to npc-profile.schema.json for want.primary validation

### Added

- Client-side PROTOCOL_VERSION enforcement — snapshot decoder rejects version mismatches with error log
- POI verb priority test in observer pipeline — asserts both verb kind and priority values end-to-end

### Changed
- Observer pipeline decomposed into two-stage system: compute_visibility_geometry (geometry) → compute_observer_snapshot (entity filtering + assembly)
- POI verb priority adjustment moved from simulation phase (interaction.rs) to perception phase (observer) — fixes D-010 information boundary violation
- compute_nearby_interactions no longer reads KnowledgeGraph — determines verb availability by proximity only, verb priority adjusted by observer
- compute_nearby_interactions scheduling moved from SimulationPlugin to BridgePlugin for explicit ordering with geometry and observer systems
- Client test snapshot updated to v4 format (Protocol.PROTOCOL_VERSION, tick_rate replaces paused)

### Added
- Content validation tooling — `make validate-content` validates campaign YAML files against JSON schemas, maps files by directory context
- Entity::to_bits() roundtrip test — guards against bevy version changes silently breaking wire IDs
- TickRate switch mid-accumulation test — verifies Half→Full→Paused→Half transitions preserve accumulator state

- Content schema definitions (#386) — 8 JSON Schema files (draft 2020-12) for district, location, npc-profile, dialogue-pool, monologue-pool, triangle, routine, fact-catalog validation
- PROTOCOL_VERSION constant in bridge types — versioning strategy documented (subprocess IPC, serde defaults for field evolution)
- Campaign, system, station JSON schemas for hierarchical content validation

### Fixed
- Test suite aligned with server v4 protocol enforcement — all hand-built snapshots include version field, verb priorities 1-indexed, ExamineNpc label corrected to "Observe"
- E2E proof tests resilient to entity ordering — player found by kind instead of array position, wall-hides test checks specific NPC position instead of total count, supports 3-NPC proof room layout
- Wire entity_id now uses StableId consistently across observer, observation, interpretation, and interaction systems (was Entity::to_bits() in some paths)
- Restored system/station/district hierarchical fields in district metadata (incorrectly removed during canonical_id cleanup)
- Unregistered entities in observer/interaction now log tracing::error instead of silently falling back to Entity::to_bits()

### Changed
- NearbyInteractionBuffer refactored from global Resource to per-entity Component on PlayerCharacter — multiplayer-ready (D-009)
- Observer module split into mod.rs (244 lines) + tests.rs (480 lines) — reduces module complexity

- Missing PlayerCharacter in input processing now panics instead of silent no-op
- Verb sort uses (priority, kind) tuple for deterministic ordering at equal priority
- Unregistered entity in knowledge events triggers debug_assert + error (was warn)
- District schema: canonical_id is now optional (derived from directory path at load time)
- Skills trimmed for CLAUDE.md deduplication — search-docs (-48%), ticket (-17%), review-pr (-35%) now reference CLAUDE.md for basics instead of repeating them
- Review-pr reviewer profiles extracted to `references/reviewer-profiles.md` for progressive disclosure

### Removed
- Dead generate_snapshot function in bridge/mod.rs — superseded by compute_observer_snapshot
- content/global/regions/ directory — region data absorbed into system.yaml metadata

### Fixed
- create-skill references to nonexistent init_skill.py and package_skill.py scripts
- SimBridge wire format: inputs now batch-encoded as Vec\<PlayerInput\> array per server protocol (was sending individual inputs per frame)
- SimBridge server args: positional address format ("127.0.0.1:9876") matching server CLI, port default corrected to 9876
- Wire format mismatch: LocalBridge now uses rmp_serde::to_vec_named() (named maps) matching client Protocol.gd expectations
- EOF on bridge read now returns BridgeError::Transport for disconnect detection instead of empty Vec
- WalkabilityMap rewritten from flat Vec to chunk-based HashMap per D-012 architecture (Tyre review)
- LocalBridge mutex .unwrap() → .expect() for clearer panic messages (Hoshe review)
- Documented 16MB MAX_MESSAGE_SIZE rationale in framing.rs (Hoshe review)
- Client input_mapper double-check bug (redundant event.pressed + is_action_pressed)
- Bounds validation on snapshot position arrays in game_state.gd and entity_renderer.gd
- Deterministic test snapshots (replaced Time.get_ticks_msec() with incrementing counter)
- Tween overlap in monologue_display.gd (cancel active tween before creating new one)
- SubViewportContainer missing SubViewport child in minimap.tscn
- Cargo.toml edition 2024 → 2021 for broader toolchain compatibility
- Relationship.target_name: String → target_id: u64 for entity scalability (Tyre review)
- DayPhase enum now derives Serialize/Deserialize (consistent with other enums)
- Replaced all absolute paths (macOS and Linux) with project-relative paths across round-16 docs
- Removed duplicate ROUND-16-STATUS.md from project root (content already in round-16-session-notes.md)
- Added relative-path convention to Qatux agent persona for cross-system consistency

### Removed
