+description: >
+  Generate audio assets for The Settled Reach using the Stable Audio Open API
+  (self-hosted Gradio app at tower-of-joy:11500). Use when generating any game
+  audio: ambient loops, SFX, UI sounds, monologue chimes, footsteps, or any
+  sound asset from docs/assets/audio/. Also use when the user asks about audio
+  generation, sound design pipeline, or audio asset iteration. Triggers on:
+  "generate audio", "make sounds", "create ambient", "audio pipeline",
+  "generate sfx", "stable audio", "gen audio", "sound design".
+---
+
+# Audio Generation — The Settled Reach
+
+Generate sonically consistent audio assets using the Stable Audio Open API via
+wrapper scripts at `db/connectors/audio-*`.
+
+Asset descriptions, filenames, bus routing, and design intent are documented in
+`docs/assets/audio/`. This skill provides the prompt system, generation
+workflow, and quality validation.
+
+## API Access
+
+**Never call the API directly.** Use the wrapper scripts:
+
+```bash
+# Check API health
+db/connectors/audio-health
+
+# Generate a single asset (WAV only)
+db/connectors/audio-generate "prompt text" \
+  --duration 10 --steps 100 --cfg 7 \
+  --output path/to/output.wav
+
+# Generate + post-process in one command (WAV → trim → normalize → OGG)
+db/connectors/audio-generate "prompt text" \
+  --duration 10 --steps 100 --cfg 7 \
+  --output path/to/gen/intermediate.wav \
+  --output-ogg client/assets/audio/final.ogg
+
+# Batch-generate from a manifest (preferred for multiple assets)
+db/connectors/audio-batch docs/assets/audio/batch-s10-327.json
+```
+
+### Parameters
+
+| Parameter | Default | Range | Notes |
+|-----------|---------|-------|-------|
+| `--duration` | 10 | 0-47s | Max 47s per generation. For longer loops, generate 45s with crossfade overlap. |
+| `--steps` | 100 | 10-200 | More steps = better quality, slower. Use 50 for quick previews, 100-150 for final. |
+| `--cfg` | 7 | 1-15 | Classifier-free guidance. Higher = more prompt-adherent but less natural. 5-9 is the sweet spot. |
+| `--output` | auto | — | Output WAV file path. Auto-names from prompt if omitted. |
+| `--post` | off | — | Run trim + normalize + convert after generation. |
+| `--output-ogg` | auto | — | OGG output path (implies `--post`). Defaults to same basename as WAV. |
+| `--timeout` | 600 | — | Max wait in seconds. Generation can take 2-5 minutes on 11GB VRAM. |
+
+### Critical Constraints
+
+- **NEVER parallelize requests.** The server has 11GB VRAM and runs one
+  generation at a time. Always wait for a generation to complete before
+  starting the next. Sequential only.
+- **Generation takes 2-5 minutes** per clip depending on duration and steps.
+  Be patient. The timeout default (600s) is generous.
+- **Max 47 seconds** per generation. For 60-90s ambient loops, generate 45s
+  clips and crossfade-stitch in post-processing.
+
+## Prompt Assembly
+
+Every generation uses three parts:
+
+```
+[SONIC FAMILY PREFIX] + [CATEGORY TEMPLATE] + [ASSET DESCRIPTION from docs/assets/audio/]
+```
+
+Never call the API with just the asset description. Always prepend the sonic
+family prefix and matching category template.
+
+- **Sonic palette and families:** Read `references/sonic-palette.md`
+- **Category templates:** Read `references/category-templates.md` and match by
+  asset type (ambient, sfx, ui)
+- **Asset description:** Look up the specific asset in `docs/assets/audio/{category}.md`
+
+## Batch Workflow (Preferred)
+
+For generating multiple assets, use a manifest file. This reduces prompt
+approvals to 2: one Write (manifest) + one Bash (batch run).
+
+### 1. Create the manifest
+
+Write a JSON manifest to `docs/assets/audio/batch-{sprint}-{ticket}.json`:
+
+```json
+{
+  "description": "Sprint 10 ambient + world SFX batch",
+  "output_dir": "client/assets/audio",
+  "gen_dir": "client/assets/audio/gen",
+  "defaults": {
+    "steps": 100,
+    "cfg": 7,
+    "lufs": -16,
+    "quality": 6
+  },
+  "assets": [
+    {
+      "id": "AMB-001",
+      "filename": "amb_station_base.ogg",
+      "method": "sao",
+      "duration": 45,
+      "steps": 150,
+      "cfg": 5,
+      "prompt": "[sonic family prefix] + [template] + [description]"
+    },
+    {
+      "id": "UI-005",
+      "filename": "sfx_monologue_chime.ogg",
+      "method": "synth",
+      "synth": {
+        "type": "harmonic",
+        "duration": 0.8,
+        "fundamental": 1200,
+        "harmonics": [
+          {"freq": 2400, "db": -12},
+          {"freq": 3600, "db": -24}
+        ],
+        "attack_ms": 15,
+        "sustain_ratio": 0.2,
+        "decay": "exponential"
+      }
+    }
+  ]
+}
+```
+
+Asset `id` values must match IDs in `docs/assets/audio/{category}.md` (e.g.,
+AMB-001, SFX-002, UI-005). This couples the manifest to the asset inventory.
+
+### 2. Run the batch
+
+```bash
+# Full run
+db/connectors/audio-batch docs/assets/audio/batch-s10-327.json
+
+# Dry run — preview what would be generated
+db/connectors/audio-batch docs/assets/audio/batch-s10-327.json --dry-run
+
+# Generate only specific assets
+db/connectors/audio-batch docs/assets/audio/batch-s10-327.json --only AMB-001,AMB-002
+
+# Skip assets that already have OGG files
+db/connectors/audio-batch docs/assets/audio/batch-s10-327.json --skip-existing
+```
+
+### 3. Update asset docs with prompts
+
+After the batch completes, write the exact prompts used back into the
+Prompt/Notes column of `docs/assets/audio/{category}.md`. The manifest records
+what was generated; the asset docs record what we have.
+
+### Manifest fields
+
+| Field | Required | Notes |
+|-------|----------|-------|
+| `id` | yes | Asset ID from docs (AMB-001, SFX-002, UI-005) |
+| `filename` | yes | Output filename (must match asset doc) |
+| `method` | yes | `sao` (Stable Audio Open) or `synth` (harmonic synthesis) |
+| `duration` | SAO only | Duration in seconds |
+| `prompt` | SAO only | Full assembled prompt |
+| `steps` | no | Override default steps |
+| `cfg` | no | Override default CFG |
+| `synth` | synth only | Synthesis parameters (see below) |
+
+### Synth parameters
+
+| Field | Default | Notes |
+|-------|---------|-------|
+| `type` | harmonic | Only `harmonic` supported currently |
+| `duration` | — | Duration in seconds |
+| `fundamental` | — | Fundamental frequency in Hz |
+| `harmonics` | [] | List of `{"freq": Hz, "db": dB}` objects |
+| `attack_ms` | 10 | Attack time in milliseconds |
+| `sustain_ratio` | 0.2 | Fraction of duration at full level before decay |
+| `decay` | exponential | `exponential` or `linear` |
+
+## Single Asset Workflow
+
+For one-off generation or iteration on a specific asset:
+
+1. Find the asset in `docs/assets/audio/{ambient,sfx,ui}.md` — note filename,
+   duration, bus, method, and design intent.
+2. Read `references/sonic-palette.md` for the sonic family prefix.
+3. Read `references/category-templates.md` for the matching template.
+4. Assemble the full prompt.
+5. Run `db/connectors/audio-health` to verify the API is up.
+6. Run `db/connectors/audio-generate` with `--post` or `--output-ogg` to
+   generate and post-process in one step.
+7. Verify the output (file size, duration).
+8. Update the asset status and prompt in `docs/assets/audio/{category}.md`.
+
+## Iteration Workflow
+
+For each asset, generate 4-6 candidates:
+
+1. **Generate candidates** — vary the prompt slightly (add/remove descriptors,
+   adjust CFG between 5-9). Run each generation sequentially — never in
+   parallel.
+2. **Solo test** — does each candidate sound right alone?
+3. **Stack test** — play the candidate alongside other layers. Does it mask or
+   clash?
+4. **Fatigue test** (loops only) — can you listen for 5+ minutes without a
+   jarring repeat?
+5. **Close-your-eyes test** — does it create a mental image or sensation?
+6. Select the best candidate (post-processing is already done if `--post` was
+   used).
+
+## Post-Processing (Standalone)
+
+If you need to post-process separately (e.g., re-normalizing an existing file):
+
+```bash
+# Full pipeline: trim → normalize → convert
+db/connectors/audio-post pipeline input.wav --output output.ogg
+
+# Individual steps
+db/connectors/audio-post trim input.wav
+db/connectors/audio-post normalize input.wav --lufs -16
+db/connectors/audio-post convert input.wav --output output.ogg
+```
+
+## Manual Synthesis (Insert-Tech Sounds)
+
+For sounds under 200ms (cursor hover, weapon aim), Stable Audio Open cannot
+produce meaningful output. Use manual synthesis via `tooling/synth_ui_sounds.py`
+or the batch manifest's `method: "synth"` with harmonic parameters.
+
+For complex synthesis beyond the `harmonic` type (FM, filtered noise, bandpass
+impulse), write a custom script in `tooling/` following the pattern in
+`tooling/synth_ui_sounds.py`.
+
+## Quality Checklist
+
+After generating, verify:
+- Sound matches the sonic family (insert-tech = synthetic/precise, organic = warm/natural)
+- Frequency range doesn't mask other layers (check docs/assets/audio/)
+- Duration matches spec
+- No unwanted artifacts (clicks, pops, digital noise at start/end)
+- Loop point is clean (ambient loops only)
+- Volume sits well relative to other assets (LUFS normalized)
+- Passes the close-your-eyes test
+
+## File Placement
+
+Generated assets go to `client/assets/audio/` with exact filenames from the
+asset docs. Intermediates go to `client/assets/audio/gen/` (gitignored).
+
+AudioManager discovers assets by directory scan — filenames must match exactly.

-
-## Prompt Assembly

-
-## Iteration Workflow
-
-For each asset, generate 4-6 candidates:

-5. **Close-your-eyes test** — does it create a mental image or sensation?
-6. Select the best candidate, trim, normalize, convert.
-
-## Post-Processing
-
-After selecting the best generation:
-
-```bash
-# Trim silence from start/end
-ffmpeg -i input.wav -af "silenceremove=start_periods=1:start_silence=0.1:start_threshold=-50dB,areverse,silenceremove=start_periods=1:start_silence=0.1:start_threshold=-50dB,areverse" trimmed.wav
-
-# LUFS normalize to -16 LUFS (broadcast standard, good for game audio)
-ffmpeg -i trimmed.wav -af loudnorm=I=-16:LRA=11:TP=-1 normalized.wav
-
-# Convert to .ogg for Godot
-ffmpeg -i normalized.wav -c:a libvorbis -q:a 6 output.ogg
-
-# For loops: verify loop point
-ffplay -loop 0 output.ogg
-```
-
-For ambient loops, create crossfade overlap:
-```bash
-# Create a 45s loop with 3s crossfade overlap
-# (manual: export 48s, crossfade first 3s with last 3s in Audacity)
-```
-
-## Manual Synthesis (Insert-Tech Sounds)
-
-For sounds under 200ms (cursor hover, weapon aim), Stable Audio Open cannot
-produce meaningful output. Use manual synthesis instead:
-
-```python
-# Example: 50ms cursor hover tick
-import numpy as np
-import wave
-
-sr = 44100
-duration = 0.05  # 50ms
-t = np.linspace(0, duration, int(sr * duration), endpoint=False)
-freq = 3200  # Hz
-signal = np.sin(2 * np.pi * freq * t)
-envelope = np.exp(-t * 80)  # exponential decay
-audio = (signal * envelope * 32767).astype(np.int16)
-
-with wave.open("cursor_hover.wav", "w") as f:
-    f.setnchannels(1)
-    f.setsampwidth(2)
-    f.setframerate(sr)
-    f.writeframes(audio.tobytes())
-```
-
-## Quality Checklist
-
-After generating, verify:
- Sound matches the sonic family (insert-tech = synthetic/precise, organic = warm/natural)
- Frequency range doesn't mask other layers (check docs/assets/audio/palette.md)
- Duration matches spec
- No unwanted artifacts (clicks, pops, digital noise at start/end)
- Loop point is clean (ambient loops only)
- Volume sits well relative to other assets (LUFS normalized)
- Passes the close-your-eyes test
-
-## File Placement
-
-Generated assets go to `client/assets/audio/` with exact filenames from the
-asset docs:
-
-```
-client/assets/audio/
-  amb_station_base.ogg       # Ambient bus
-  amb_workplace_layer.ogg    # Ambient bus
-  amb_bar_layer.ogg          # Ambient bus

+
+# Start Sprint Skill
+
+Prepare a team branch for sprint work: sync with main, load the sprint
+briefing, and present actionable next steps.
+
+## Workflow
+
+### 1. Determine the team
+
+The current branch IS the team. Read it with:
+```bash
+git branch --show-current
+```
+
+Valid team branches: `server`, `client`, `copy`, `audio`, `visual`, `ci`.
+
+If on `main`, follow the **Main branch workflow** below instead of
+the team branch workflow (steps 2–8).
+
+---
+
+## Main branch workflow (sprint lifecycle management)
+
+When `/sprint-start` is run on `main`, assess the current sprint state
+and do the next right thing. Query the database to determine the state:
+
+```bash
+db/connectors/sqlite-query "SELECT id, name, status FROM sprints ORDER BY id DESC LIMIT 3"
+```
+
+Then follow the **first matching case**:
+
+### Case A: An active sprint exists
+
+First, check whether the sprint's work is actually done:
+
+```bash
+db/connectors/sprint status
+```
+
+This shows ticket counts by status (done, in_progress, backlog).
+
+Also check for open PRs that may contain completed work waiting for
+review or merge:
+
+```bash
+tea pr list --login schweitz --repo jpmschweitzer/settled-reach --state open --output simple
+```
+
+Report the full picture to the user:
+- Ticket progress (done / in_progress / backlog counts)
+- Open PRs (if any — these represent work that's done but not merged)
+
+**If tickets remain unfinished** (in_progress or backlog) **or open PRs
+exist**, do NOT close the sprint. Instead, report the current progress
+and ask the user what they want to do:
+
+- **Continue working** — switch to a team branch and run `/sprint-start`
+  there to resume work
+- **Review & merge PRs first** — (only if open PRs exist) merge pending
+  work before deciding whether to close
+- **Close anyway** — proceed with the close workflow below (carries over
+  unfinished tickets)
+
+Use `AskUserQuestion` to confirm. Do not proceed to A1 unless the user
+explicitly chooses to close.
+
+#### A1. 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.
+
+#### A2. Bump the version
+
+The project version scheme is `v0.1.{sprint_number}`. After closing
+sprint N, the version is `v0.1.N`.
+
+Update `project.yaml`:
+- Set the `version` field to `0.1.N` (this is the source of truth).
+
+Update `server/Cargo.toml`:
+- Set `version = "0.1.N"` in `[package]`.
+
+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.
+
+#### A3. Commit the release
+
+Stage and commit `project.yaml`, `server/Cargo.toml`, and `CHANGELOG.md`:
+```
+chore(meta): release v0.1.N
+```
+
+#### A4. Tag the release
+
+```bash
+git tag v0.1.N
+```
+
+#### A5. Push
+
+```bash
+git push && git push --tags
+```
+
+#### A6. Check for a planned sprint
+
+After closing, re-query the database. If a sprint in `planning` status
+exists, continue to **Case B**. Otherwise, report the close and suggest
+running `/sprint-plan`.
+
+---
+
+### Case B: No active sprint, but a planned sprint exists
+
+A sprint is ready to activate. Verify it looks complete:
+
+1. Check that briefing files exist at `docs/sprints/sprint-N/`:
+   ```bash
+   ls docs/sprints/sprint-N/
+   ```
+2. Check the ticket count:
+   ```bash
+   db/connectors/sprint status --sprint N
+   ```
+
+If briefings are missing or the sprint has 0 tickets, report the gap
+and suggest running `/sprint-plan` to complete planning.
+
+If everything looks ready, activate the sprint:
+
+```bash
+db/connectors/sprint start
+```
+
+Then report:
+- Sprint activated (name, ticket count per team)
+- Remind the user to switch to a team branch and run `/sprint-start`
+  there (or `cd` into the relevant worktree)
+
+---
+
+### Case C: No active sprint and no planned sprint
+
+Nothing is ready. Report the state and suggest running `/sprint-plan`
+to plan the next sprint.
+
+---
+
+## Team branch workflow
+
+### 2. Sync with main
+
+```bash
+git fetch --all
+git merge origin/main --no-edit
+```
+
+If the merge has conflicts, report them and stop — do not force-resolve.
+
+### 3. Load sprint context
+
+Run the sprint CLI to get the full context dump in one shot:
+
+```bash
+db/connectors/sprint start-work
+```
+
+This auto-detects the active sprint and current team from the branch.
+It outputs: sprint metadata, briefing paths, decision refs, actionable
+tickets, blocked tickets, and done tickets.
+
+If no active sprint is found, report that and stop.
+
+### 4. Read the sprint briefing
+
+Read the briefing file(s) listed in the `start-work` output
+(e.g. `docs/sprints/sprint-6/server.md` and `joint.md`).
+If no matching briefing exists for the team, suggest running
+`/sprint-plan` to generate one.
+
+### 5. Load ticket details
+
+For tickets that need more detail than the `start-work` summary provides:
+```bash
+db/connectors/ticket show <id>
+```
+
+### 6. Read key decisions
+
+Read the decision files referenced in the sprint briefing so the agent has
+full architectural context before starting work.
+
+### 7. Mark tickets in progress and present the work plan
+
+Mark all actionable (unblocked, non-done) tickets in the sprint as
+`in_progress`:
+
+```bash
+db/connectors/ticket status <id> in_progress
+```
+
+Then output a summary:
+- Sprint name and goal
+- Branch status (clean merge or conflicts)
+- Tickets marked in_progress (list with IDs)
+- Blocked tickets (and what blocks them)
+- Key decisions loaded
+- Suggested first task (lowest ID unblocked ticket)
+
+### 8. Confirm and spawn the team
+
+Before spawning agents, use `AskUserQuestion` to confirm the work plan and
+agent lineup with the user. If declined, stop.
+
+Once confirmed:
+
+#### 8a. Parse agents from the briefing
+
+Extract agent names from the `**Agents:**` line. Format:
+```
+**Agents:** Name (role), Name (role), ...
+```
+
+Map each name to its `subagent_type` (lowercase):
+- "Dudley (simulation)" → `dudley`
+- "Stig (UI)" → `stig`
+- "Tyre (architecture)" → `tyre`
+- "Hoshe (QA)" → `hoshe`
+- "Mellanie (author)" → `mellanie`
+- etc. (see `.claude/agents/` for full roster)
+
+#### 8b. Create the team
+
+```
+TeamCreate(team_name: "sprint-{N}-{team}")
+```
+
+This makes you the team lead.
+
+#### 8c. Create tasks from tickets
+
+For each ticket in the briefing, create a task:
+
+```
+TaskCreate(
+  subject: "#{id}: {title}",
+  description: "Full ticket details from step 5, plus briefing notes
+    and integration points for this ticket.",
+  activeForm: "Working on #{id}: {short_title}"
+)
+```
+
+After creating all tasks, mirror the dependency chain from the briefing
+using `TaskUpdate` with `addBlockedBy`.
+
+#### 8d. Spawn agents
+
+For each agent from the `**Agents:**` line, spawn a teammate in the
+background. Spawn all agents in parallel (one message, multiple Task calls):
+
+```
+Task(
+  subagent_type: "{name_lowercase}",
+  team_name: "sprint-{N}-{team}",
+  name: "{name_lowercase}",
+  prompt: "You are on the {team} team for Sprint {N}.
+    Branch: `{team}`
+
+    RULES:
+    - GIT: Do NOT run any git commands (commit, push, pull, merge,
+      checkout, branch, stash, tag, etc.). All git operations are
+      handled by the team lead.
+    - DB SCRIPTS: When calling ticket/sprint/sqlite scripts, use
+      the exact command with no wrappers or chaining. Examples:
+        db/connectors/ticket show 528
+        db/connectors/ticket list --sprint {N}
+      Do NOT prepend python3, do NOT chain with && or ;, do NOT
+      add cleanup commands. Just the bare command.
+
+    1. Read the sprint briefing: docs/sprints/sprint-{N}/{team}.md
+    2. Read the decision files referenced in the briefing.
+    3. Check TaskList for available work.
+    4. Claim an unblocked task (TaskUpdate with owner: your name),
+       mark it in_progress, and implement it.
+    5. When done, mark the task completed and check TaskList for
+       the next available task.
+
+    Use `db/connectors/ticket show <id>` for full ticket specs.",
+  description: "Sprint {N} {team}: {name}",
+  run_in_background: true
+)
+```
+
+#### 8e. Report
+
+Output to the user:
+- Team name: `sprint-{N}-{team}`
+- Agents spawned (names and roles)
+- Tasks created (count actionable vs blocked)
+- How to interact: `SendMessage` to talk to agents, `TaskList` to
+  check progress
+
+You are now the team lead. Agents work autonomously — monitor via
+`TaskList`, communicate via `SendMessage`, and handle blockers as
+they arise.

+- 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
@@ -15,6 +158,11 @@ Format based on [Keep a Changelog](https://keepachangelog.com/).
 - 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
