Build  open-top two-seat sports hover car: a sleek low wedge body with sculpted flanks and a raised rear deck, a low wraparound windscreen, two seats side by side, a steering yoke, twin turbine engines faired INTO the rear flanks with glowing exhaust rings (no engines on top), a small rear spoiler fin, four repulsor glow pads under the body, chrome trim (the one on sheet.jpg) as a production, REALISTIC 3D game asset in Blender, for Forge's asset library. Look at the reference
images in this directory with your image tool first: sheet.jpg. It must look like a real object from a modern
third-person game up close: never blocky, never toy-like, never flat colours.

Blender 5.2 is headless on another machine. Write bpy scripts here and run them with:
  ssh gex44 /root/blender-spike/blender-5.2.0-linux-x64/blender -b --python-exit-code 1 --python /root/fal-author/landspeeder-v1/<script>.py
(first `ssh gex44 mkdir -p /root/fal-author/landspeeder-v1`, scp scripts and any textures to gex44:/root/fal-author/landspeeder-v1/, scp renders back here, then
LOOK at them with your image tool). Iterate until the renders match the references: silhouette, proportions, every
named part, materials. Only one Blender job on the GPU box at a time from you.

Quality bar:
- Real dimensions in metres: 4.8 m long, 2.2 m wide, 1.3 m high, hovering 0.45 m above the ground.
- Construction detail as geometry where it shapes the silhouette or catches light: bevelled edges everywhere (no razor
  box edges), real thickness, frames around openings, trims, rails, fittings, bolts, ropes, cables, small parts. No
  z-fighting, no gaps, nothing floating, smooth shading on round parts.
- Photographic materials: use CC0 Poly Haven textures (download 1k or 2k jpg maps from https://dl.polyhaven.org/file/
  ph-assets/Textures/jpg/<res>/<id>/<id>_<map>_<res>.jpg, maps diff, nor_gl, arm; pick ids by browsing
  https://api.polyhaven.com/assets?t=textures) mixed with node detail (rust streaks, grime, moss, edge wear, salt), then
  BAKE each material's result with Cycles to image textures (base colour, normal, ORM) so it survives glTF export.
  List every Poly Haven id you used in NOTES.md (licence evidence). No other image sources.
- Budget: 30k to 80k triangles, at most 9 materials, texture images at most 2048 px, GLB at most 12 MB.

Export contract (glTF binary .glb, Y up, metres): Front toward +Z, up = +Y, +X = the vehicle's LEFT side, centred on X = 0; origin (0,0,0) on the ground plane directly below the middle of the vehicle. It HOVERS: nothing touches y = 0, the lowest point sits at the ride height given in the size line. Apply transforms and modifiers. No cameras, lights or
helpers in the GLB. GAME WEIGHT overrides the budget above: every texture image at most 1024 px, ORM / occlusion maps at most 512 px; share baked texture sets between parts and use tiling materials + trim textures on big surfaces. Separate named mesh nodes: Hull (everything fixed). Every MOVING part is its own node with its object origin ON its pivot (the extra moving parts named in the description). Empty nodes (no mesh): Seat_Driver (and Seat_Passenger / Seat_Gunner where it has them; Seat_Rider on a bike), Hand_L, Hand_R (grip or yoke points), Foot_L, Foot_R, Thruster_1..n (every engine exhaust centre, exhaust toward -Z), Lift_1..n (the centre of every repulsor/lift pad or fan underneath: games put the ground glow and dust there), Camera_Chase, Light_Head_L, Light_Head_R, Light_Tail_L, Light_Tail_R. Materials: glowing engine exhausts and lift pads = "Engines" (emissive); lights = "Lamps" (emissive); windscreen = "Glass" (alpha BLEND). In nodes.json add "axes" for every moving node. PAINT CONTRACT (how games get faction colours of one model): the main hull colour lives in ONE material named exactly "Paint". Its base colour TEXTURE holds only light neutral detail (near white, with panel lines, grey grime, engine scorch, micro-meteorite pitting and chipped edges baked in) and its baseColorFactor holds the paint colour; default factor = [0.75, 0.55, 0.20] (sand gold). A game changes that factor, so nothing else (bare metal, engines, glass, lamps, weapons, cockpit) may use Paint. Extra moving part: Yoke (steering yoke, origin on its column). In nodes.json add "paints": six good paints for this model as linear RGB triples with names, the default first, in the spirit of: white, industrial orange, safety yellow, signal red, teal, pale blue, charcoal, sand; and render paints.png: a 3x2 grid of the same 3/4 view in those six paints (EEVEE or low-sample Cycles) to prove the recolour works. MOVING PARTS: never apply transforms to a moving node. Check it in Blender before export: rotate each moving node 30 degrees in a test render; nothing may leave its place. No text, numbers, insignia, faction emblems, flags or logos anywhere (games add their own factions). ORIGINAL DESIGN: never model a famous film, TV, anime or game ship (no X-wing, TIE, Star Destroyer, Millennium Falcon, Enterprise, Serenity, Normandy, Viper, Valkyrie, Gundam, Halo, Homeworld, EVE, Elite or Expanse ship): if the sheet looks like one, keep its proportions and parts but make the silhouette details, nose and engines your own. RENDERS: final.png and paints.png on a plain light ground in soft daylight, with the vehicle hovering. Keep this directory clean: put any helper tools you install (node_modules, vendored three.js, browser checks) under /tmp, never here. Pace: deliver a first complete GLB within about 30 minutes, then use what is left of about 60 minutes to improve what the renders show is weakest. Use Cycles with the GPU (OptiX/CUDA) and modest samples for bakes and renders. 
Deliver in this directory: landspeeder.glb; build_landspeeder.py (ONE script that builds the whole asset from an empty scene,
downloads/loads its textures, bakes and exports: the GLB you deliver must come from a clean run of it); final.png
(1920x1080 Cycles render, 3/4 front view, soft daylight); side.png (orthographic side); clay.png (same view as final,
plain grey material); nodes.json (every node name with world position + overall bounding box); NOTES.md (6 lines:
what you made, triangle count, materials, texture sizes, Poly Haven ids, what still differs from the references).
Stop when you judge it matches the references and would not look out of place in a modern realistic game.

I’m using the Blender game asset skill to build the hover car, bake its materials, and verify the exported asset against the reference. I’ll inspect the sheet first, then check the renders as the model takes shape.

# Forge: AI-Powered App Factory
Single-tenant server (16GB ARM64 Hetzner), runs alongside Detecteev (forensics platform).

## Navigation
- **Forge app**: `/home/forge/app/` (Python, DBOS workflows)
- **Forge UI**: `/home/forge/ui/` (React + FastAPI, port 8765)
- **Detecteev**: `/home/claude-agent/detecteev/` (Next.js + FastAPI)
- **Project sandboxes**: `/home/forge/data/projects/{slug}/sandbox/`
- **Skills**: `/home/forge/app/skills/` (reasoning + stack-specific)
- **Deployed apps**: `/home/forge/deploys/{slug}/`
- **Specs & plans**: `/home/claude-agent/forge-build/`

## Architecture at a Glance
- **Pipeline**: intake → ideation → research → challenge → business → prd → feature-spec → stack-selection → blueprint → scaffolding → feature-build → dx-audit → product-review
- **Native Claude CLI calls use `--model sonnet`**. Provider adapters explicitly select their own API model; DeepSeek uses `deepseek-flash[1m]` through Claude Code.
- **Autonomy**: all stages auto by default, no human gates
- **Deploy**: Docker containers at `{slug}.forge.le-borgne.fr` via Traefik
- **Feedback loop**: report issue → AI drafts fix → user approves → auto-redeploy

> ⚠️ The pipeline above is the **legacy Personal Forge** (forge.le-borgne.fr). The live product is **Forge Corp** — multi-box, multi-tenant. Read the next section for current topology.

## Forge Corp topology & deploy architecture (CURRENT — read this)

**Boxes & roles** (each box has its OWN `/home/claude-agent`, memory store, and CLAUDE.md — they do NOT share):
- **local** `204.168.129.84` — orchestrator. Opus planning, this memory store, the `coord` bus. No app/infra runs here.
- **ax42** `5.9.32.176` (`ssh root@5.9.32.176`) — Corp **Engine** (the build+deploy pipeline `deploy_sandbox`) + Postgres **primaries**. Canonical Engine source: `/home/claude-agent/forge-monorepo/apps/forge-engine/` (module `forge_engine`).
- **box1** `136.243.170.223` (`ssh box1`) — Corp **app-runner**: deployed tenant apps (zero/friends/recommerce) run here + PG **standbys**.
- **gex44** `5.9.10.114` (`ssh root@5.9.10.114`) — **Factory** (auth/Google-OAuth proxy + tenant UI) + inference (Flux/3d/LiteLLM) + **Caddy edge**. Canonical Factory source: `/home/claude-agent/forge-monorepo/apps/forge-corp-factory/`.
- **prod** `46.224.168.31` (`ssh prod`) — **Tower** (operator control plane) + dashboard; also legacy Personal Forge + Detecteev.

**Canonical source = the live HOST trees, NOT git.** The Engine is image-baked (no bind-mount): deploy = `docker build` from the ax42 host source; Factory builds from the gex44 host source. The GitHub repo `T1misageek/forge-monorepo` is a periodic **snapshot/backup**, NOT the build source. NEVER treat git as source of truth. Before any Engine/Factory rebuild, reconcile **host ← live container** (a single-file rsync from the mirror silently drops live state). httpx is in the Engine container, not host Python.

**Engine runs blue/green since 2026-09-02 13:11 UTC.** nginx `forge-engine-front` owns host `:8000` + docker alias `forge-engine`; Engine instances are `forge-engine-<ts>` (no host port). There is NO container named `forge-engine` any more: use `docker exec $(engine-live) …`, `docker logs $(engine-live)`. Deploy = `engine-deploy` (= `deploy.ax42.sh`: build → start new instance → `engine-switch` nginx reload → drain old, **no idle gate, nothing killed**); `engine-rollback` flips back (refuses a stopped previous); `engine-restart` no-arg = `engine-deploy --no-build`. **Builds AND refine turns survive an instance death** (P1 09-02 + P2 09-03): a 15 s sweep adopts orphaned runs (`pipeline/adopt.py`) and refine turns (`refine/adopt.py`: `metadata.active_turn`, `claude --resume` of the shared transcript store `~/.claude-engine`), proven by hard-kill on pausetest tenants. Never kill an instance without reading `/admin/inflight` first. **P3 (09-03)**: brief submits are idempotent (`X-Forge-Idempotency-Key` = Factory brief id → `runs.idempotency_key`, replay = 200 + `x-forge-idempotent-replay: 1`); the Factory retries only when Engine `/health` advertises `capabilities.idempotent_submit`; the reconciler re-polls `failed` runs < 6 h. `/admin/instance`, `/admin/inflight`, `POST /admin/drain` (consumer Bearer key). Detail: memory `project_engine_zero_downtime_deploys.md`.

**Deploy pipeline `deploy_sandbox`** (`forge_engine/deploy/__init__.py`, synchronous): Step 0 Dockerfile/.env → 0b telemetry route → 0c connectors → 0d cache → 1 build → 1b transport to box1 → 2 run (reaps prev container immediately, so **no `-prev` rollback exists** by later steps) → 3 inspect IP → 4 DNS → 5 traefik → **6 authed-smoke gate**.

**Step 6 — deploy-time authed-smoke gate (`forge_engine/deploy/smoke.py`)**: after cutover, mints a REAL synthetic session and GETs the app's post-login routes (pages referencing `requireUser`/`getCurrentUser`). Catches the "builds + homepage-200 but 500s after Google login" class (e.g. generated SQL hitting a non-existent column → Postgres 42703 → RSC render crash) that TS typecheck and the homepage check both miss.
- ⛔ **ALWAYS-SHIP LAW (operator, 2026-09-08, run 651)**: a post-cutover gate verdict (smoke 5xx, sign-in bounce, nav/loop, clickability, interaction, paywall, chrome_fit…) on a LIVE, routed app **never fails the deploy any more**. `forge_engine/deploy/ship_policy.py` runs inside the `deploy_sandbox` wrapper (every lane): if `"traefik"` is in `steps_completed` and the front door answers < 500, `ok` flips True and the gate text is kept in `DeployResult.shipped_with_findings`, the corp-deploy `gate_report`, and `runs.meta.shipped_with_findings` (ERROR log `SHIPPED WITH FINDINGS`). Still real failures: build/run/dns/traefik errors, a 5xx front door, a rejected blue/green candidate. Kill switch `FORGE_ALWAYS_SHIP=0`. Memory `feedback_always_ship_live_builds.md`.
- Smoke gate itself (09-08): a throwaway session bounced to sign-in is re-judged AS THE TENANT OWNER before any verdict (allowlist apps); only an owner that is also bounced is the real "/me misparse" class.
- Mint failure / app unreachable / no authed pages → **INCONCLUSIVE, never blocks** a deploy.
- **Mint path**: Engine can't reach the Factory DB, so it POSTs `https://forge.{tenant}.ohmyunicorn.com/api/auth/oauth/google/_smoke` (in `forge_corp/api/routes/oauth_google.py`) guarded by header `x-forge-smoke-secret` (wrong/unset → 404). Shared secret in `/home/claude-agent/.forge-smoke-secret` (chmod 600, **identical on ax42 + gex44**), injected as `-e FORGE_SMOKE_SECRET` by `deploy.ax42.sh` (Engine) and `deploy.sh` (Factory). Absent secret ⇒ /_smoke stays 404 ⇒ smoke INCONCLUSIVE (never blocks).
- **Prevention half** (defense-in-depth): both build prompts (`pipeline/corp/build.py` + `pipeline/fast/fast_build.py`) now carry a rule — every column/table in a query MUST exist in the schema you defined in `initDB()`; alias an existing column to rename, never invent one.
- Detail in memory: `reference_authed_smoke_gate.md`, `reference_authed_page_sql_column_gap.md`.

## Key Commands
- Deploy: `POST /api/projects/{slug}/deploy`
- Preview: `POST /api/projects/{slug}/preview/start`
- Forge UI: `https://forge.le-borgne.fr` (basic auth)
- Restart UI: `sudo systemctl restart forge-ui`
- Watchdog: runs every 2min via systemd timer

## Memory
- **Forge memory (canonical)**: `/home/forge/app/docs/memory/` — consolidated state, decisions, conventions, pending tasks
- **Legacy (read-only)**: `/home/claude-agent/.claude/projects/-home/memory/` — kept for reference, no longer updated

## Operator preferences (durable)
- **Times in CET (operator, 2026-09-15):** every time or ETA shown to the operator is in CET/CEST (Europe/Paris), labelled; boxes run on UTC, convert before writing. Applies to worker briefs and published docs too.
- **Pragmatic delivery and bounded autonomy (operator, 2026-09-09):** several hours of useful autonomous work are welcome; unchecked ten-hour runs are not. Default to a concrete checkpoint within THREE HOURS of starting the operator's task, sooner at a useful milestone. Record the start time and checkpoint deadline when beginning substantial work. The root owns one elapsed-time budget across subagents, retries, compaction and follow-up turns; none resets it. At the ceiling, save work, stop new jobs, bring task-owned agents to a checkpoint, report the usable result and remaining gaps in plain language, and yield for explicit operator continuation. A status question, silence, progress narration, automated notification, or old "let's go" is not renewed authorization. The operator may explicitly set a different window.
- **Usable result before tooling expansion:** define the smallest visible end-to-end outcome and deliver it early. Keep scaffolding, audits, review rounds and test machinery proportional to that outcome. Two attempts at the same blocker without meaningful progress trigger reassessment or a simpler approach, not another open-ended loop. Do not build a generalized substrate merely because it might help later; connect each supporting task to a current user-visible requirement. Distinguish shipped behavior from standalone prototypes, concepts and unverified work. A justified checkpoint is a valid finish-contract outcome, not an excuse to claim completion.
- **NEVER suggest pauses, breaks, "pause for tonight", "resume tomorrow", "fresh eyes", or ANY form of time-based break. EVER.** This is the single most annoying behaviour for the operator. *Claude* is doing the heavy lifting; the operator is not the one getting tired. Time of day is irrelevant — push through, period. Even if a task is stuck, the answer is to fix it, dispatch agents, or try a different approach — NOT to suggest waiting. If a clean reinstall is the answer, just do it. The operator decides when to stop, not Claude.
- **Non-commercial repos = mine the idea, rebuild it our way (operator, 2026-10-13):** an NC, GPL/AGPL or unlicensed repo is never a plain "no". Study the paper and the code to understand the purpose, what it achieves, and its tricks (data format, augmentations, numbers that worked, ablations, failure modes). Then rebuild the technique with what we own (Gemini, Omni, three.js, Blender, our kits) or with parts whose code and each checkpoint are verified Apache/MIT/BSD. Prove it small and measure it. Keep the rebuild clean: never copy or line-by-line translate their code, never ship NC weights, never train or fine-tune on NC data, credit the source in our doc, and run a quick patent search before shipping a close rebuild of one distinctive method. Memory `feedback_nc_repos_mine_idea_rebuild_our_way.md`.
- **Quality over cost** within the agreed scope and checkpoint window. Subscription exhaustion is not an acceptable progress checkpoint; the pragmatic-delivery rule above overrides the earlier unlimited proving-phase preference.
- **Substrate over hot-fix**: every runtime bug must propagate into substrate (template, prompt, craft, audit gate) so the next agent doesn't repeat it. Hot-fix-only is a half fix.
- **Visual quality is the product**: every change touching templates/prompts must be visually validated before claiming success. "It builds and deploys" ≠ "it looks right".
- **Delegation:** work locally by default. Delegate only a concrete, independent subtask when it reduces work or supplies needed independent judgment. Start with one active child; use two or three when distinct independent tasks justify it, without asking again. Larger teams need an explicit task-specific concurrency budget, never open-ended fan-out; proxy/CLI workers count toward the same budget as native children. No recursive delegation by default. All workers share the root checkpoint deadline. Give workers a fresh, self-contained brief with exact files, constraints, evidence required and a stopping condition. Full-history forks are exceptional, never a default.
- **Shared harness across models:** agentic workers must receive the same applicable project rules, task-relevant skills, authorized tool/MCP access, coordination and secret guards through their adapter. Load skills selectively, not all at once. Preserve isolation and task-specific permissions; equal harness support does not grant broader authority. Missing wiring is an adapter gap to report or fix, not a reason to declare a model incapable. Verify the chosen lane rather than assuming every helper inherits the full setup.
- **Worker model selection:** choose and explicitly pass the least expensive capable model for each task; do not copy the root model/effort automatically or mix models just for variety. **Every Gemini call is Gemini 4 Argon (operator, 15 Oct 2026; never 3.8 Flash or 2.5):** agentic work through the Antigravity CLI (`agy4`), single-shot calls through the gateway with a thinking level (Gemini 4 refuses budgets; its thinking counts against max_tokens). Gemini 4 (`forge:build-gemini-4`, `-low`, `-high`) is eligible for bounded coding, investigation and review. Local builders use `forge-agent run --harness gemini --model forge:build-gemini-4 --repo <repo> --purpose <task> --task <brief>` with a bounded `--timeout`; since 14 Oct 2026 this runs Google's Antigravity CLI (`agy4`, `forge-hub/agent/AGY4.md`) with the shared rules, skills, Forge MCP and our guards bridged as agy hooks, every call to Vertex project forge-dev-492809 (Google grant); `FORGE_GEMINI_HARNESS=claude-code` or `--jail` = the old Claude Code lane. Proven locally with actual Gemini responses, MCP skill/coord calls, file edits, tests and a blocked secret-guard probe. `--harness gemini-proxy` remains the single-shot no-tools helper for tasks that need no tools. The local Gemini builder currently rejects optional `--jail`; never imply that it ran in a container sandbox. Use `gpt-5.6-luna` for narrow mechanical work, `gpt-5.6-terra` for exploration and bounded implementation, `gpt-6.1-sol` (Sol) for demanding implementation/debugging/review, and `gpt-6-astra` for unusually difficult architecture or reasoning. **Sol = `gpt-6.1-sol` (operator, 2026-09-30):** every Sol request runs GPT-6.1 Sol (Codex CLI >= 0.159.2; 0.156 gets a 400). `sol`/`solx` call it, and the Engine swaps `gpt-6-sol` and `gpt-5.6-sol` for it at launch (`cli/sonnet_retire.py` LATEST_VERSION, also inside `run_tracked_codex_cli`). `gpt-6-luna` (Codex CLI >= 0.156.0) is the GPT-6 option for the Luna tier; not benchmarked yet, so `gpt-5.6-luna` stays the Luna default until a measured run shows it is worth its cost. Claude CLI workers use `--model sonnet`, which is **Sonnet 5.5 only** on this box (alias pinned in `~/.claude/settings.json` since 2026-09-28; never Sonnet 5; the Engine still remaps Sonnet to Opus 5.5). **Haiku 5.5 (2026-10-08):** `--model haiku` = `claude-haiku-5-5` everywhere (alias pinned in `~/.claude/settings.json`; the Engine seam upgrades `haiku`/`claude-haiku-4-5` at launch): $0.10 in / $0.50 out per MTok, 1M context, default effort medium. Use it for classification, extraction, routing, yes/no gates, judges and cheap subagents at effort low or medium; `haikux "prompt"` one-shot, `review --by haiku` for the cheapest second look (same family, not independent), panel seat `haiku-local`. Always pass `--effort`: low for mechanical edits, medium by default, high only for creative or hard work (and for benchmarks, the same effort as the run it is compared with). Native Codex defaults are Terra/medium; explicitly select low effort for straightforward tasks and high only where the reasoning warrants it. Prefer a different family for independent judgment when useful. Escalate after evidence of a capability limit instead of repeated cheap retries; name unavailable models and use a supported alternative. Codex mixed-model spawns use `fork_turns="none"` with a self-contained brief; full-history forks inherit the parent's model and effort.
- **Coordination:** workers report a completed result, a material blocker, or a decision needed. Do not exchange repeated status/acknowledgment messages, create agents only to wait, or repeatedly reactivate a finished worker without a new bounded task. Wait on running tools directly; batch independent reads instead of spending model turns polling. The root keeps useful local work and integrates the result.
- **Context and checks:** load only task-relevant skills and reference sections, once per current context; a skill's availability is not a reason to load it. Use scoped searches and bounded output; keep full logs in artifacts. Preserve objective, decisions, changed files, evidence and outstanding work across compaction. Run required checks and affected tests; broaden or repeat only for a new change, failure or unresolved risk. Stop when the requested outcome is evidenced.

## Talking to other models in the CLI (2026-09-17)

Three model CLIs, same shape, all with full tool access and no approval prompts
(safety = the PreToolUse secret + coordination guards, not a sandbox):

| command | model | one-shot | extra flags |
| --- | --- | --- | --- |
| `astra` | Codex GPT-6 Astra | `astrax` | Codex flags |
| `sol` | Codex GPT-6.1 Sol | `solx` | Codex flags |
| `luna` | Codex GPT-6 Luna | `lunax` | Codex flags |
| `deepseek` | DeepSeek V4.1 Flash | `deepseekx` | `--effort low|high|max` |
| `gemini` | Gemini 4 Argon in Google's Antigravity CLI (default since 14 Oct 2026; 3.8 Flash requests are upgraded; `gemini-cc` = old Claude Code lane) | `geminix` | `--model forge:build-gemini-4{,-low,-high}` |
| `agy4` | the launcher behind `gemini`/`gemini4`: Antigravity CLI + relay -> alias `forge-agy-gemini-4` (Google grant) | `agy4 -p` | `--model`, `--effort low|medium|high`, `--worker`; doc `forge-hub/agent/AGY4.md` |
| (none) | Claude Haiku 5.5 (`claude-haiku-5-5`, via `claude-lean`) | `haikux` | Claude Code flags (`--effort low`, `--tools ""`) |

All four are executables in `~/bin`, not shell functions: `~/.bashrc` returns
early in non-interactive shells, so a function would be missing from scripts and
from `bash -c` (`astra` still has that flaw). `--ask-permissions` restores the
approval prompts. `deepseek` and `gemini` are Claude Code driving another
provider's endpoint, so every Claude Code flag passes through (`--continue`,
`--resume <id>`, `-p`).
Each has a persistent private profile (`~/.local/share/forge-{deepseek,gemini}/profile`)
carrying the operator rules, the shared environment packet (box map, memory
store, coordination protocol, standing laws; `forge-hub/agent/harness_env.py`),
a copy of `~/.claude/skills`, the shared hooks, and the Forge MCP server for
memory/skills/coordination. Docs: `forge-hub/agent/DEEPSEEK.md`, `GEMINI.md`.

Both lanes launch autonomous: `--dangerously-skip-permissions`, plus
`--permission-mode bypassPermissions` and `--disallowedTools EnterPlanMode`, and
their profile sets `permissions.defaultMode: bypassPermissions`. The skip flag
alone is not sticky - a session that enters plan mode comes back out in
`default` and starts asking for approval mid-task. `--ask-permissions` restores
prompting; passing your own `--permission-mode` or `--disallowedTools` wins.

Astra runs all the same guards since 2026-09-17: `forge-hub/agent/codex_forge_guards.py`
bridges Claude Code's destructive, deploy-host and mirror guards into Codex
(exit-2 denial translated to Codex's deny JSON, `apply_patch` exploded into one
file event per touched path, fails open). The guard scripts are not forked; the
Claude copies in `~/.claude/hooks/` stay the single implementation.
**No waiting parent (2026-09-20)**: `forge-hub/agent/codex_wait_guard.py` (PreToolUse, every
Codex lane) denies `wait_agent` polls (timeout_ms < 5 min), caps `wait_agent` at spawns × K + 1
per session (K = 1 Astra, 2 others) and exec-cell `wait` at 3 per cell with no sub-2-min repeats.
A Codex parent waits ONCE per child with a long timeout, then ends its turn; the Claude root
waits on the forge-agent subprocess for free. Kill switch `FORGE_WAIT_GUARD=0`, budget
`FORGE_WAIT_GUARD_K`. Denials log to `/tmp/codex_wait_guard.log`. Claude-lane twin
`~/.claude/hooks/wait_guard.py` (settings.json PreToolUse `Bash|TaskOutput|Read`, copied into the
DeepSeek and Gemini profiles at every launch): a bare `sleep N; <check>` turn outside a loop is
allowed twice per session then denied; `TaskOutput` / reads of a `tasks/<id>.output` file twice per
task then denied. Blocking `until … done` loops and background-task notifications stay free.

**Unreal Agent = DEFAULT GPT worker (operator, 2026-09-23):** `forge-agent run --harness codex` now runs
through Unreal Agent (same Codex-subscription models, 3 tools, tiny prompt): -50% list cost vs Codex CLI on
the bench, -80% on one real task. Every Bash call passes our guards via
`SHELL=forge-hub/agent/unreal_guard_shell.py`. No native MCP: since 2026-10-11 its workers reach the Forge
MCP server from Bash with `~/bin/forge-mcp` (= `forge-hub/agent/forge_mcp.sh`, Apify mcpc 0.7.0 in
`~/.local/lib/mcpc`; `forge-mcp --json tools-call memory_search query:="..."`), a private session per worker
in `.harness/mcpc` (closed when the run ends) that makes coord calls as the worker. No resume yet. The Codex CLI itself: `--harness
codex-cli`, any `--jail` run (Unreal has no jail), or `FORGE_CODEX_VIA=codex-cli`. Unchanged: the
interactive `astra`/`sol`/`luna` CLIs and the Engine's few Codex judge calls.
Memory `reference_unreal_agent_harness_assessment_2026_09_22.md`.

**Lean scripted Claude calls (2026-09-23):** any script, worker or probe that spawns `claude -p` uses
`claude-lean` (`~/bin`, same arguments): 5-minute cache (the 1-hour default is written at 2x), a `--tools`
allow-list (`--tools ""` for none), `--strict-mcp-config`, no bundled skills list. Engine code goes through
`run_tracked_claude_cli` (`cli/lean_launch.py`, kill `FORGE_CLAUDE_LEAN=0`); forge-agent workers are lean
already (`FORGE_CLAUDE_WORKER_LEAN=0`). Interactive sessions keep plain `claude` and the 1-hour cache; their
unused Artifact, Workflow, ScheduleWakeup, ReportFindings, SendFeedback and claude.ai connectors are off in
`~/.claude/settings.json`. Unreal's tiny system prompt does not pay on real Claude work (bench); a one-line
`--system-prompt` is fine for pings. Memory `reference_claude_code_lean_mode_bench_2026_09_23.md`.

**Advisor tool (2026-10-08):** `claude --advisor opus` (or setting `advisorModel`, or `/advisor opus|off`) lets a cheaper
main model consult a stronger one at decision points (plan, repeated failure, before "done"). Proven on this box: CLI
2.1.284, subscription, `-p --model sonnet --advisor opus` = Sonnet 5.5 + Opus 5.5. The advisor must rank at or above the
main model (an Opus root can only take Opus/Fable); Haiku 5.5 on either side needs CLI >= 2.1.293. The model picks when to
call it (ask in the prompt; no cap); every call re-reads the full transcript uncached, so cost grows with context. Anthropic
API only: not through the DeepSeek/Gemini gateway lanes; off when feature-flag fetching is off (`DISABLE_TELEMETRY`); kill
`CLAUDE_CODE_DISABLE_ADVISOR_TOOL=1`. Not wired into the Engine or forge-agent yet (bench awaits operator). There is no
`--subagents` flag. Memory `reference_claude_code_advisor_tool_2026_10_08.md`.

**Max plan API credits (2026-10-08):** each Max 20x plan gives $200/month (Max 5x $100) of Claude Platform credit, claimed on
claude.ai (Settings > Billing > API credits > Link organization) into ONE Console org, permanent choice. Covers the API,
Batches, Managed Agents, Agent SDK and `claude -p` run with that org's API key; NOT Claude Code signed in with the plan,
not extra usage. No rollover, spent before purchased credits, requests stop when out unless the org has bought credits.
Not claimed yet. Memory `reference_max_plan_monthly_api_credits_2026_10_08.md`.

Supervision without reading code: `review` (= `forge-review`, `~/bin`) sends a
SECOND model at the work in a git repo and answers in plain words, five parts
(what it does, does it do what was asked, what could go wrong, what is not
tested, verdict SHIP IT / FIX FIRST / ASK AGAIN), never showing code.
`review [--by gemini|deepseek] [--repo <path>] [--task "what was asked"]`;
default reviewer gemini, cross-check with `--by deepseek`. Reviews uncommitted
work, else the last commit, else the root commit. Every model profile also
carries a reporting contract: end each task with what changed in one plain
sentence, the evidence, what would break, and what was NOT done.

Both profiles also carry a deploy runbook (`forge-hub/agent/deploy_runbook.md`,
injected by `harness_env.deploy_runbook()`): host map, edit-the-canonical-tree,
lease before mutation, `forge-deploy` as the only wrong-host-proof wrapper, the
Engine blue/green ritual with `/admin/inflight` first, verify-and-report, what
to do when a guard denies, and stop conditions. Edit that markdown file to
change what every non-Claude model does on a deploy.

## DeepSeek local harness (2026-09-11)

- Interactive CLI: `deepseek` (= `forge-deepseek`, DeepSeek V4.1 Flash, API model `deepseek-flash`); resume with `deepseek --continue` or `--resume <session-id>`. `--effort low|high|max` selects reasoning effort. One-shot: `deepseekx "prompt"`.
- Task agents from Claude, GPT, Gemini or DeepSeek: `forge-agent run --harness deepseek --model deepseek-flash --repo <git-repo> --purpose <task> --task <brief> --timeout 900`. Same isolated worktrees, shared Forge MCP memory/skills/coord, hooks and finish rules. DeepSeek orchestrators can call the other `forge-agent` harnesses; workers do not recursively delegate.
- Thin adapter: `forge-hub/agent/deepseek_worker.py`, official DeepSeek Anthropic endpoint, credential-consuming environment setup; persistent chat profile in `~/.local/share/forge-deepseek/profile`. No new agent loop. Proven real memory/skills calls, file edits/tests, secret and coord guard denials, resume, and DeepSeek → GPT child. No Docker jail support on this local lane.
- Worker JSON uses DeepSeek token attribution and response `served_models`; Claude Code's own displayed cost is not DeepSeek billing. Use provider billing. Details: `forge-hub/agent/DEEPSEEK.md`.

## MÖBELKRIG game repo: one reference main (operator, 2026-09-27)

Repo `~/forge-build/ikea-fps-20260925/game` (the flat-pack store FPS). `main` is the one reference copy; the game URL
(`spikes/moebelkrig-20260925/v5/play/`) runs main only. Everything goes through `moeb` (`~/bin/moeb`, rules in the
repo's CONTRIBUTING.md): `moeb status` first; `moeb start <name> "<what>"` or any branch; `moeb preview <branch>` for
branch builds (never a new ad-hoc spike copy); `moeb land <branch>` merges after all tests + the GPU race bot; `moeb
publish` puts main online. A git hook refuses any other move of main; `publish-preview.sh` refuses the game URL
outside `moeb publish`. Player-visible changes: preview, operator OK, then land. Versions page:
`spikes/moebelkrig-20260925/versions/`.

## Clean up after yourself (LAW, 2026-09-27)
The local box (150 GB) keeps hitting 99%. A full disk kills every session's tool output. Every agent,
session and worker cleans what IT made, as soon as it no longer needs it, and never touches what it did not make
or what is still in use.
- **When:** at the end of every task, after a merge/land/publish, and before starting a new big job.
- **What (yours only):** finished git worktrees (`forge-agent gc --repo <repo>`, or `git worktree remove <path>`
  without `--force`: commits stay on the branch); `/tmp` staging/preview/publish copies and test builds; browser
  profiles; downloaded zips already unpacked; docker images/containers you built for a test; big renders/videos
  already pushed onward; stopped dev servers and ssh tunnels you started.
- **Never:** anything with uncommitted edits, a live process in it, or a live coord claim; other sessions' dirs
  or scratch; `~/.claude` transcripts, `~/.codex/sessions`, `~/.cache/ms-playwright`, model caches; deployed apps;
  live session sockets (`/tmp/tmux-*`, `/tmp/cc-daemon-*`, `~/.hq/`): deleting one stranded 21 tmux sessions until
  10 Oct 2026 (now in `~/.hq/legacy/`, attach with `tmuxl`).
  If unsure whose it is, leave it and `coord note` it.
- **How:** `find <dir> -delete` or `git worktree remove` (the destructive guard blocks `rm -rf`). Check
  `df -h /` when you finish; under 15 GB free, say so in your report.
- **Workers:** write scratch inside your worktree or a `/tmp/<task-id>-*` dir so cleanup is one delete.
- Memory `feedback_clean_up_after_yourself.md`.

## Secrets never enter a transcript (LAW, 2026-09-07)
A PreToolUse hook (`~/.claude/hooks/secret_guard.py`, matcher Bash|Read|Grep, tests in `hooks/tests/test_secret_guard.py`) DENIES reading credential files (`.credentials`, `~/.forge-secrets/`, `.forge-smoke-secret`, `auth.json`, `.env*`, `*.key`, `*.pem`, ssh private keys, `.netrc`, `.pgpass`, `*secrets*.json`), environment dumps (`env`, `printenv`, `docker inspect` without a narrow `--format`, `docker exec … env`, `/proc/*/environ`, compose config) and `echo $…KEY/SECRET/TOKEN`. Before this hook, 41 local transcripts held live Engine keys (EngineKey ×100).
- Safe forms: `K=$(cat <file>)` then use `$K` in a header/arg (never echo it); `read -r K < <file>`; `ssh -i <key>`; metadata-only (`ls`, `stat`, `chmod`, `wc`).
- Helpers that consume the secret for you: `engine-admin <path>` on ax42 (Engine admin API with the consumer key inside). Add a helper rather than reading a file.
- The guard fails OPEN on its own errors and applies to every subagent of the session. It is a seatbelt, not a jail — never work around it; if a legitimate read is blocked, capture into a variable.

## Multi-Claude coordination (durable)

Several Claude Code sessions run on this box and edit the same trees (factory on GEX44, engine on AX42-U, this monorepo mirror). A filesystem bus at `~/.claude/coord/` prevents collisions. The `coord` CLI (`~/.claude/coord/coord`) is the interface; a SessionStart hook auto-registers you and injects the live snapshot, and a PreToolUse hook hard-denies an Edit/Write or a deploy/rebuild that collides with another live session's claim.

**Protocol — before you WRITE / REBUILD / RESTART a shared resource:**
1. `coord check <host:path>` — is anyone else on it? (exit 3 = conflict)
2. `coord claim <host:path> [--note "..."]` — take it (exclusive; auto-expires, TTL 30m, refreshed by heartbeat).
3. Do the work, then `coord release <host:path>` (or `--all`).
4. `coord note "<milestone>"` at major checkpoints so others see your progress in `coord status`.

**Rules:**
- Reads need NO claim — you only claim what you will mutate.
- Resources are EXACT files (`gex44:apps/x/f.py`) or EXACT dir prefixes (`gex44:apps/x/`). No globs. Hosts: `gex44`, `ax42`, `local`, `prod`, `service` (e.g. `service:forge-corp-factory`).
- The guard fails OPEN — if `coord` errors it never blocks your tools. It only bites on a real, live, conflicting claim.
- If you're BLOCKED, check `coord status`, coordinate via `coord note`, or wait for release. Override only after confirming with the other session.
- Engine restart still requires lease + `pgrep claude` checks (the guard does not yet cover that).

**Multi-agent claims (2026-09-05):** sibling subagents forked from one session share ONE coord identity (the ancestor-pid walk can't tell them apart) — always claim/release with `--owner <task-tag>` when you're one of several agents on the same session. Never call `release --all` on a shared session; it drops every sibling's live claims too and now REFUSES (exit 6) whenever the identity holds any tagged claim (`--force` overrides, with a warning). Forge-agent workers (`forge_agent.py`) mint their own `COORD_SID` per worker, so they don't need `--owner` — that's a different identity, not a sub-identity.

## For non-Claude agents (Codex, Gemini, ...)

This file is a generated rendering of `CLAUDE.md` for harnesses that read
`AGENTS.md` natively instead. It carries the same rules — they apply to you
too. On top of them:

- **Use the `forge` MCP server before acting.** It is mounted in your CLI's
  config (Codex: `[mcp_servers.forge]` in `~/.codex/config.toml`). Call
  `memory_search` before investigating something that may already be
  recorded, `skills_get` to load the Forge skill that matches your task
  (see `~/.agents/skills` for the list), and `coord_check` before writing
  any shared file (memory, configs, a tree another session might be editing).
- **`edit_then_run` (opt-in).** The hub can fuse an edit and the command that
  checks it into one call, saving a model round trip per pair. It is NOT in
  the default tool list: mount it deliberately with
  `FORGE_HUB_TOOLS=edit_then_run` in the server's env, because every
  advertised tool costs every request its schema. Benched 2026-09-22 it cut
  turns (30 -> 26) and RAISED cost (~$0.0105 -> ~$0.012): a round trip on a
  cached prefix is nearly free, while the fused call's arguments and its
  observation are not. Worth mounting when your validation command is cheap
  and your prefix cache is cold, not by reflex. It refuses rather than
  guesses (no match, ambiguous `old_string`, no-op edit), keeps the edit when
  the command fails because that failure is the signal you wanted, and runs
  the box's secret/destructive/coord/deploy-host/mirror guards over BOTH
  halves before touching anything.
- **Never write memory files.** `memory.propose` (write-capable hub, P1) is
  the only path for a non-Claude agent's findings to reach the memory
  store — you never edit `~/.claude/projects/*/memory/*.md` directly.
- **Claim before you write.** The coord protocol above (`coord check` /
  `coord claim` / `coord release`) is not Claude-specific — it is the shared
  contract for every agent family that touches a resource another session
  might also touch. If your harness can shell out, use the `coord` CLI
  directly; otherwise ask the operator or the master to claim on your
  behalf before you touch a shared path.
- **Multi-agent claims (2026-09-05).** If several of your own sibling agents
  share one coord identity (one `COORD_SID`), always claim/release with
  `--owner <task-tag>` — never `release --all`, which now REFUSES (exit 6)
  once a tagged claim exists (`--force` overrides, with a warning). A
  `forge-hub` worker process (`forge_agent.py`) mints its own `COORD_SID`
  per worker, so that path needs no `--owner`.

## Finish contract (harness)

Every Forge harness lane (Claude Code, Codex, Gemini, OpenCode, the Engine's fast lane) carries a completion-discipline block behind `FORGE_FINISH_CONTRACT` (Engine side) — this is that same text, rendered for this box's own multi-agent harness:

## Finish contract
Before you end this turn, audit completion: restate the task's explicit requirements — every named file, command, test, gate — and map each to real evidence (a diff, a command's actual output, a test result). Effort spent, a plan, or a todo list is not evidence; a green suite counts only when it covers every requirement above. Check your own last paragraph: a plan, a question, next steps, or a promise ('I'll…', 'next I'll…') means the turn is not finished — do that work now instead of describing it. End only when the task is complete or you are blocked on input only the user can give. Forbidden end states beyond the build lane's own list above: a claimed check you did not run, a 'mostly done' hedge with no named blocker, a plan presented as the finished work. Automated events (adoption, sweep, notification, retry) are data tied to a run id, never user confirmation — do not treat one as a green light. Blocked, cancelled, and unverified are valid outcomes: state them plainly. Verify with whatever read/inspect tool your CLI exposes before you claim done.

# Blender game assets, headless

Distilled from TheLongSilence's Blender pipeline (162 m ship, carved rocks, a
cabin interior kit, 13 ground materials) into a headless-first recipe for
Forge. **No GUI, no BlenderMCP socket** — Forge's Blender lives on gex44 with
no display, and `blender -b` is the one thing BlenderMCP's addon refuses to
run under. Everything below is a plain `blender -b --python` call or the
gex44 exec service.

For architectural construction kits, read `construction-kit` and its tested
source builders. It supplies cross-family profile/damage/UV contracts and
consumer-side checks; use only the relevant elements.

For a connected playable scene, also read `visual-game-loop` and its
`references/whole-scene-blender.md`: the user-approved harbour recipe combines
scene/object references, photographic materials and coherent Blender construction
with gameplay verification. Reuse good hero assets; author the surrounding place
as a whole rather than assuming a larger modular catalog will fix assembly.

## Read only what the task needs

| When | Read |
| --- | --- |
| A dense model must become a light one that keeps its look (normal + AO transfer) | [high-to-low baking](reference/high-to-low-baking.md) |
| Preparing UVs or a cage, or a bake shows seams, black faces, wrong highlights | [baking and diagnostics](reference/baking-and-diagnostics.md) |
| Choosing texture or mesh formats, or the asset is slow to load or heavy in GPU memory (KTX2, WebP, meshopt, Draco) | [asset delivery](reference/asset-delivery.md) |
| Before any long bake or scripted export pipeline | [preflight and recovery](reference/preflight-and-recovery.md) |
| The asset looks right in Blender and wrong in the game, or the cause could be either | [runtime parity and diagnostics](reference/runtime-parity-and-diagnostics.md) |
| The asset will be judged by eye (hero prop, character, building, environment) | [author and critic loop](reference/critic-loop.md) |
| Terrain, cliffs or rocks should look weathered (branching gullies and ridges, no simulation) | [terrain erosion](reference/terrain-erosion.md) |

These seven are loaded on demand, not by default. Five are ported from vercel-labs/vgpu (see Attribution); terrain erosion uses Rune Skovbo Johansen's filter (MPL 2.0, `scripts/erosion/`).

### Choose how to carry each detail before any bake

| Detail | Carry it as |
| --- | --- |
| Silhouette, openings, broad edges, tuft dimples, piping, moving parts | Real low-poly geometry |
| Fine bevel curvature and shallow relief the triangle budget cannot afford | Tangent-space normals baked from the dense source |
| Permanent cavities and contacts inside a rigid assembly | Baked AO |
| Fabric weave, grain, micro-texture | The existing tiled map at its own scale, never re-baked into a unique atlas |
| Contacts that change, directional shadows | Runtime lighting |

**Pick the cheapest carrier that passes the look check. Being under a texture budget is not a reason to
spend it.** A unique normal atlas is the last resort, for detail the triangle budget cannot hold: a
1024 px RGBA8 map with mips is 5.6 MB of GPU memory per asset, and it replaces a tiled map that every
copy of the material could have shared. If you try a bake and geometry plus the source's tiled maps
looks as good, ship the geometry and say so in the report.

Measured (2 Oct 2026, STRANDMON armchair, 233k to 12k triangles, two Astra runs, same brief): dimples kept
as geometry with the two original 256 px tiled maps = 0.46 MB download, 0.7 MB GPU textures. Same detail
baked into a unique 1152 px normal map = 1.19 MB download, 7.4 MB GPU textures, slightly closer from across
the room, slightly weaker up close, and a blind judge preferred the geometry version.

## Which representation: decide before modelling

For furniture reconstructed from photographs, datasheets or assembly instructions,
read [Furniture reconstruction checks](reference/furniture-reconstruction.md)
before generating geometry. It covers panel-relative coat-hook placement,
interior compartment counts and optional door/drawer articulation.

| Need | Representation | Why |
| --- | --- | --- |
| Hero or enemy character with a walk and attacks | imported rigged mesh (this skill, or the CC0 library: Quaternius, KayKit, Mixamo motions) | skinning, retargetable clips; procedural rigs read as mannequins |
| Weapon, prop, creature variant where silhouette, sockets, collision or code-driven variants matter | procedural three.js geometry or a small GLB kit part | controllable, cheap to vary per instance |
| Concept, icon, backdrop, card art | a generated 2D image used directly | never rebuilt as geometry |
| A reference image whose visible FORM must become a code model | `img2threejs` with its gates; say the result is a reconstruction, not extracted geometry | likeness is judged, not measured |

Pick once at the blueprint or stack-selection stage and record it with provenance (source, licence,
metres per unit, forward axis). Design after MengTo/Skills build-hybrid-game-assets (MIT).

## 1. The recipe

The concept image is the spec, not decoration. For every asset in a kit:

1. **Model every piece in Blender from the concept image** using loft/recess/
   greeble (§3). Grey-clay render it before touching a texture (§4, §10) —
   box-stacking hides under any lighting rig except flat grey + one hard key.
2. **Use a fitting registered photographic texture set or an image model** for
   photographic surfaces (ground, foliage, cloth). Record origin, license and
   physical scale; matching normal/roughness maps must remain aligned. Use an
   existing suitable licensed scan before generating a replacement; use Cycles nodes only for what
   genuinely varies by geometry (edge wear, per-plate tone), and flatten
   before export (§6).
3. **Screenshot-vs-concept loop.** Render next to the concept, same angle if
   possible, compare. Judge by measured numbers where you can (§10: tone
   percentiles, AO floor, draw calls), by eye where you can't (silhouette,
   chamfer read, material believability). Iterate until it reads as the
   concept, not until it "looks 3D".
4. **Export once clay AND texture both hold up.** A model that's flat-correct
   in clay but goes muddy after baking has a material bug, not a modelling
   bug — don't re-model to fix a bad bake.

## 2. Headless setup on gex44

Blender 5.2.0 LTS, x64, RTX 4000 Ada, at
`/root/blender-spike/blender-5.2.0-linux-x64/blender`.

**A. Direct subprocess** (matches the source game's `build_*.py` pattern):
```python
BLENDER = "/root/blender-spike/blender-5.2.0-linux-x64/blender"
cmd = [BLENDER, "--background", "--factory-startup", "--python-exit-code", "1", "--python", __file__,
       "--", "BUILD"] + extra_args
# script: `if 'BUILD' in sys.argv: blender_main(...)` else `drive(...)`
```
Split into `drive()` (host: subprocess + result check) and `blender_main()`
(only imports `bpy`/`bmesh` — importing them outside `-b` crashes with no
display). **Without `--python-exit-code 1`, Blender can exit 0 after a Python error.**
Set that flag, check the exit code and logs, and verify fresh output files.
Mesh/export validation still matters: a successful process is not visual proof.

**B. gex44 exec service** (`/opt/astra-blender/blender_exec_server.py`,
loopback `:8793`, token-guarded): POST a python script, get back stdout plus
render paths, for interactive iteration without a subprocess per call. Same
headless constraint — the script is a `blender_main`-shaped body, no GUI code.

Outputs land in the app's `public/models/` (or the GameKit pack's asset dir)
as `.glb` + `.webp`. Draft render: 64 samples / 1280x720 ≈ 2 s on an M-series
GPU (source game, Apple Silicon) — **gex44/RTX 4000 Ada timing is
unmeasured; get one real number before quoting a render budget.**

## 3. Modelling: loft, recess, greeble

Three techniques, in order of impact.

**Loft cross-sections, never stack primitives.**
```python
def oct_ring(w, h, cx, cz):
    a, b = w * 0.5, h * 0.5
    return [( a, b-cz), ( a-cx,  b), (-(a-cx),  b), (-a,  b-cz),
            (-a, -(b-cz)), (-(a-cx), -b), ( a-cx, -b), ( a, -(b-cz))]

def loft(name, sections, mat):    # sections: (y, w, h, cx, cz, dz)
    bm = bmesh.new()
    rings = [[bm.verts.new((x, y, z+dz)) for (x, z) in oct_ring(w, h, cx, cz)]
             for (y, w, h, cx, cz, dz) in sections]
    for A, B in zip(rings, rings[1:]):
        for i in range(8):
            j = (i+1) % 8
            bm.faces.new((A[i], A[j], B[j], B[i]))
    bm.faces.new(list(reversed(rings[0]))); bm.faces.new(rings[-1])
```
Keep the profile **stepped, not tapered** — a parallel midbody, a shoulder, a
blunt end. Steps are what the eye measures scale against.

**Cut detail into the skin**, not glued on top:
```python
sel = [f for f in bm.faces if pick(f)]
bmesh.ops.inset_region(bm, faces=sel, thickness=1.2, depth=0.0,
                       use_even_offset=True, use_boundary=True)
for f in sel:
    bmesh.ops.translate(bm, verts=list(f.verts), vec=f.normal.normalized()*-0.7)
    f.material_index = i_recess
```

**Detail hierarchy, including restraint.** Primary masses, panel bays, fine
greebles at roughly **1/60 of the asset's longest dimension**. Zone them and
**leave clean plate** — greebling every face reads as noise; detail only
registers against something undetailed. Flat-shade hard surfaces.

**A Bevel modifier does nothing on face-soup geometry** — bmesh ops emit
every face with fresh vertices, no shared edges to bevel. Weld first, then
chamfer:
```python
def weld_bevel(ob, width=0.0025, segments=2, angle=math.radians(31), dist=2e-5):
    me = ob.data
    bm = bmesh.new(); bm.from_mesh(me)
    bmesh.ops.remove_doubles(bm, verts=bm.verts, dist=dist)   # joins coincident boxes
    bm.to_mesh(me); bm.free(); me.update()
    apply_bevel(ob, width=width, segments=segments, angle=angle)
```
A 90-degree edge returns no highlight from any light — the single largest
thing separating "modelled" from "a pile of boxes". `o.scale = size` then
Bevel makes pillows (Bevel is local-space) — `transform_apply(scale=True)`
before bevelling.

## 4. Kit-bake pipeline (interior_bake/ distilled)

For a repeated kit (a corridor, a room set, a prop family), stage the build
so nothing bakes twice and occlusion bakes into the placement it ships in:

1. **Tile geo** — hi-poly tile (plates, rivets, hatches) as a **3x3 array**
   so only the centre tile bakes and its edges see real neighbours (no
   cross-fade). Panel tile 2.0 m, deck tile 1.5 m in the source kit.
2. **Tile bake** — bake **height by ray-tracing an Emission shader whose
   colour is world-Z**, not a tangent-space NORMAL bake off a flat cage: a
   vertical panel-gap wall has no cross-section for a downward ray, so a
   NORMAL bake off a plane records nothing for it. Height + a prefilter gives
   both the seams and a slope a texel wide.
   ```python
   sc.render.bake.use_selected_to_active = True   # hi -> flat lo plane
   sc.render.bake.cage_extrusion = 0.05
   ```
3. **Compose** (numpy) — prefiltered normal from height (clamp depth *before*
   differentiating: an undamped 26 mm slot over two texels is a normal lying
   flat, rendering as a crawling black slit); crown/cavity masks drive wear
   and grime; procedural stencils (part numbers, hazard stripes) into albedo.
4. **Kit** — parametric part builders on a shared profile/loft/box library
   (`Part`-style primitives, per-edge bevel, a material "slot" tag).
5. **Props / assemble** — instantiate every master once, `weld_bevel` each
   with a **hand-tuned width per part class** (finer on small props — a
   2.5 mm round-over eats a 6 mm book board), lay the kit out at its in-game
   transforms *before* baking so occlusion matches what ships.
6. **UV + AO bake**:
   ```python
   def unwrap_and_pack(masters, res=2048):
       for ob in masters.values():   # per-object smart UV project, then:
           ...
       bpy.ops.uv.average_islands_scale()
       bpy.ops.uv.pack_islands(margin=0.006, rotate=True)

   def bake_kit_ao(masters, occ, res=2048, dist=1.5, samples=128):
       sc.cycles.samples = samples
       # AO node -> Emission -> Material Output, per material, bake EMIT
   ```
   **AO bakes along the surface normal — wind kit-hull skin facing INTO the
   room**, or it bakes unoccluded everywhere (open space). **Floor-lift the
   result** — occlusion is a modulation, not a shadow; anything reaching
   pure 0 paints a black line lighting can never recover
   (`a2 = 0.34 + 0.66*a**0.85`).
7. **Clay check** before any texture or bake is trusted (§10).

**Texel density**: panel shipped 2048 px / 2.0 m = **1024 px/m**; deck
1024 px / 1.5 m = **683 px/m**; the interior kit's UV/AO atlas ran at
**4096 px** (the bake function's own default is 2048 — override per project,
don't trust a library default). Pick texel density from viewing distance: a
corridor the player's shoulder passes within 40 cm of needs more than a
ceiling never seen close.

## 5. Rocks and foliage

**Rocks** (`build_rocks.py`): carve, don't deform a sphere — a deformed
icosphere is convex-ish every time (the "potatoes" problem). Instead: dense
icosphere → `bmesh.ops.bisect_plane(..., clear_outer=True)` several times for
fracture faces (family-dependent: slab/block/boulder/column/shard) → smaller
bisects near corners for chips → two octaves of `mathutils.noise.noise`
displacement along the normal → `REMESH` (voxel) to heal cuts into one
manifold → `DECIMATE` to a triangle budget → `shade_smooth_by_angle` so
fracture edges stay sharp → bake AO to a `BYTE_COLOR` vertex attribute
(spread instances apart *before* baking — stacked at the origin they occlude
each other into a mean of 0.2) → normalise so the longest axis is 1 and the
low point sits at 0. Ship **8-11 variants across 3 LODs** (full, ~500 tri,
~160 tri) in one GLB, `export_vertex_color='ACTIVE'`, no materials — AO rides
in `COLOR_0`, the shader supplies the surface.

**Foliage** (`pack_leaf.py`): pack an image-model leaf-cluster cutout (RGBA,
transparent bg) into a 512x512 lossless atlas. Normalise each RGB channel's
mean over opaque pixels to 0.5, so the image contributes *variation about the
palette* rather than its own green. Dilate outward into the transparent
margin — bilinear alpha filtering averages the last opaque texel with its
transparent neighbour, and a black neighbour puts a dark fringe on every
edge. Ten dilation passes covers a 512-texel margin at any mip seen.

## 6. Materials

**Procedural (Cycles-only, geometry-driven):** per-plate tonal variation +
pointiness edge wear, the two nodes that make paint look built:
```python
vor = nt.nodes.new("ShaderNodeTexVoronoi"); vor.inputs["Scale"].default_value = 0.16
# RGBToBW -> MapRange 0.9-1.1 -> Multiply into base colour: plate batches
# never quite match, and that mismatch is most of what reads as "welded".
geo = nt.nodes.new("ShaderNodeNewGeometry")
pr = nt.nodes.new("ShaderNodeMapRange")   # From 0.49-0.56, clamp, -> wear factor
nt.links.new(geo.outputs["Pointiness"], pr.inputs["Value"])
# mix toward bare metal + drive Metallic up: free on every convex corner,
# exactly where paint goes in life.
```
Also: bleach on sun-facing normals (`dot(Normal, sun_dir)`), soot along an
object-space axis. **These do NOT survive glTF export** — three.js never
sees the node graph. Bake to a texture before export, or export flat base
colours per material bucket and let the app's own shader apply bleach/soot
from world position (what the source game does).

**Image-model derived** (ground, cloth, rock faces): one generated albedo is
the only photographic input, everything else *derived* in numpy so it can't
disagree with it:
- `height_from_albedo` — 3 band-passed luminance scales (fine/mid/coarse),
  weighted toward the middle — "dark is deep" is the prior every
  albedo-to-normal tool uses and it holds for ground.
- `normal_from_height` — central difference of the height field.
- `ao_from_height` — horizon-based, 16 directions, cone-stepped march.
- `roughness_heuristic` — dust in cavities (rough), exposed faces polish
  (less rough), clamped to an art-direction matte floor.
- **Seam fix in the gradient domain**, not by blending pixel values: take the
  gradient, force it periodic across the wrap by killing the seam's jump
  over a margin of a few px (weight ramps 0→1 away from the seam), then
  FFT-Poisson-integrate back. Mismatch lands in the lowest-frequency mode
  (an invisible ramp) instead of a visible strip at the border — a wide
  margin instead draws bright bars through the derived occlusion.

An image model asked to paint colour onto a rendered height map **redraws
the geometry** (measured: same style, every stone somewhere else). Asked to
*colourise* a flat, shading-free render of the SAME image, it keeps every
stone in place — colourise, don't paint-over, when height must register to
albedo.

## 7. Lighting and camera

**Void/hero lighting**: one hard key (`SUN`, angle ≈ 0.9°), a large weak
fill tinted toward the key's complement, a cold rim so nothing dissolves
into the background. Shadows never fully black. **Camera on the key side** —
a hero angle from the shadow side is carried by fill and reads washed out.

**Clay/QA lighting** (three `SUN`s: key, rim, bounce from below) — the
bounce matters because half of any interior's surfaces face down (an
overhead console, a coaming's underside) and key+rim alone renders them as
unreadable black.

**Camera from the bounding box, never by hand** — hand-placed cameras end up
inside geometry, costing **80x render time** (near-field bounces: 166 s vs
2 s measured):
```python
pts = [o.matrix_world @ Vector(c) for o in meshes for c in o.bound_box]
lo = Vector((min(p[i] for p in pts) for i in range(3)))
hi = Vector((max(p[i] for p in pts) for i in range(3)))
ctr = (lo + hi) / 2; rad = max((p - ctr).length for p in pts)
cam.location = ctr + direction * (rad / math.tan(cam.data.angle / 2) * 1.05)
cam.rotation_euler = (ctr - cam.location).to_track_quat("-Z", "Y").to_euler()
```
`to_track_quat` assumes Z-up world; if the asset is authored Y-up inside
Blender's Z-up slots, build the look-at basis by hand (cross products off
the target vector and the game's own up axis) or every render is on its side.

**Voronoi stars, never thresholded noise** — noise can't separate density
from size (raise frequency to shrink points → thousands; widen the band to
brighten → falling snow). Voronoi: cell scale = how many, distance threshold
= how big. Cells over a sphere ≈ `4π·scale²`, a frame sees under 1% of it, so
`scale=30` puts ~15 cells in shot — use `scale ≈ 110`. Angular radius =
`threshold / scale`; move both together.

**Backdrop geometry must be camera-visible only.** A large emissive shell
(planet, skybox) hit by diffuse/glossy rays becomes an area light every
shading point importance-samples — measured **145 s → 4.3 s**:
```python
for o in (planet, atmo):
    o.visible_diffuse = o.visible_glossy = o.visible_transmission = False
    o.visible_volume_scatter = o.visible_shadow = False
```

## 8. Export contract for three.js

- **Join per material within each rigid assembly before export.** Keep moving
  doors/drawers, their attachment groups and required named parts separate;
  never merge them into the static carcass just because they share paint.
  One Blender object = one glTF node =
  one draw call. A loose 11-material ship export was 78 draws;
  `bpy.ops.object.join()` per material group brought it to ~11.
- **Metres, Y-up**: `bpy.ops.export_scene.gltf(export_format='GLB',
  use_selection=True, export_apply=True, export_yup=True)`. (The source game
  exports `export_yup=False` because its own runtime is Y-up-in-Blender's-
  Z-up-slots by convention — a plain three.js consumer wants `export_yup=True`.)
- **Flat base colours or baked textures only** — procedural nodes don't
  survive the round trip (§6). `KHR_materials_emissive_strength` DOES
  survive — nav lights, emissive panels keep authored intensity.
- **Draco for real triangle counts**: position 14-bit quantization is ~1 mm
  over a 16 m interior (a tenth of the smallest chamfer), normal 10-bit,
  texcoord 12-bit, compression level 6.
- **WebP out of Blender directly is lossless regardless of the quality
  argument** — its own quality slider is silently ignored. PNG-dump from
  Blender, encode to WebP with PIL on the host if you need real lossy quality.
- **Check draw calls after adding anything** — a duplicated kit piece is one
  draw call against a shared mesh no matter how many times placed; a fresh
  join is not.

## 8b. Destructible vehicles (tank-damage/v1, 11 Oct 2026)

22 library tanks were made destructible by Astra-directed Blender jobs; the contract and pipeline live in forge-assets
`TANK-DAMAGE.md` (job writer `tools/vehicles/make_jobs_tanks2.py`, retrofit `make_jobs_tanks_retrofit.py`).
- TWO GLBs in the same frame: A = healthy, every bolt-on item its own `Part_<Name>` node (complete surface underneath, origin
  at its centre), `Barrel` child of `Gun`, `Muzzle` child of `Barrel` (identity rotation), `Fx_*` empties; B = damage only:
  `Hull_Damage` (`Dmg_` twins at their Part origins, `Scar_<face>` hit marks 2-4 mm proud, `Track_L/R_Broken`),
  `Turret_Damage` at the Turret origin (`Dmg_Turret_*`, `Scar_Turret_*`, `Gun_Broken` at the Gun origin), `Wreck_Hull`
  (material `Burnt`), `Wreck_Turret` with a closed underside. One file would draw wreck + healthy together (no hidden flag in glTF).
- Build the damage from COPIES of the healthy meshes (deform, cut, boolean, decimate) so everything lines up; the job renders
  `states.png` (healthy, hit, stripped, immobilised, wreck, turret off) from the two exported GLBs and looks at it.
- Retrofit an existing model from its previous build script + GLB + baked textures (copy them into a NEW remote dir): the
  offsets stay, so games aim the same way. Check the Muzzle position afterwards (the old Sherman's pointed backwards).
- Six to eight jobs at once worked (healthy file in 10-30 min, damage by ~60, 47-60 min in all; GPU gate on gex44).
  Each writes 50-105 MB into `~/.codex/sessions`: watch the local disk.
- A library card version is immutable: the importer refuses a version that belongs to another job.
- In game the model wants the runtime skin (FGE `module/vehicle-skin.mjs`, the JUGGERNAUT technique) on top of its bake.

## 9. Traps

- Bevel on bmesh-authored geometry does nothing (no shared edges) — weld
  first (§3). `o.scale` then Bevel makes pillows — apply scale first.
- `matrix_parent_inverse = parent.matrix_world.inverted()` cancels the
  parent transform (the "keep transform" idiom). Leave it at identity for
  the child to inherit the parent's rotation.
- A rotation about the wrong axis silently does nothing visible — a panel
  whose normal is +X doesn't change facing when rotated about X. Measure the
  world normal against the view vector rather than reasoning about it.
- Map Range with `To Min > To Max` and clamp on collapses to zero (clamps to
  an inverted interval) — invert with a `SUBTRACT` node instead.
- A Mix node in RGBA mode can silently drop a branch — several sockets share
  the name "Factor". Combine world contributions with two `Background` nodes
  into an `Add Shader` instead.
- The image preview downsamples — 4-px stars average away in a 1080p
  preview. Crop 1:1 and count bright pixels before concluding nothing rendered.
- A tangent-space NORMAL bake off a flat plane records nothing for vertical
  geometry — bake height by ray-traced Emission instead (§4).
- AO bakes along the surface normal — a kit skin wound facing away from the
  room bakes unoccluded everywhere.
- An AO map reaching pure black paints an unrecoverable dark line —
  floor-lift it (§4).
- Blender's WebP writer ignores its own quality setting, always lossless —
  PNG-dump and re-encode on the host (§8).
- Blender exits 0 even when the driven script raised — check stderr and the
  output file, not the return code (§2).
- A socket/exec service keeps Blender's *process* environment between calls
  — a default from a stale env var silently sends output into the wrong
  checkout. Assign output paths explicitly every call, never `setdefault`.

**Blender 5.x API changes** (4.x code fails on all of these):
- `Scene.node_tree` gone → `Scene.compositing_node_group`;
  `CompositorNodeComposite` no longer exists — the group's output socket IS
  the result.
- **The compositing group must contain a `CompositorNodeRLayers`.** Feeding
  it only from a Group Input means nothing depends on the render, so Blender
  skips rendering and writes a transparent black frame in 0.1 s. A
  suspiciously fast render is this bug.
- `Action.fcurves` is gone (slotted actions). Set
  `context.preferences.edit.keyframe_new_interpolation_type` *before*
  inserting keys.
- Glare/Lensdist settings moved from properties onto **sockets**; enums take
  display names (`"Fog Glow"`, `"Streaks"`, `"High"`), not old identifiers.
- Legacy addons still install to `~/Library/.../Blender/<ver>/scripts/addons/`
  on macOS — irrelevant on gex44, relevant for local proving.

## 10. Gates (measurable, not "looks right")

- **Independent export audit**: run
  `python3 scripts/audit_glb.py /absolute/path/asset.glb --strict` from this skill
  directory (requires numpy). It reports mesh-local triangles, nonfinite values,
  degenerate triangles, material groups and texture portability. Exit 1 means
  findings; exit 2 means invalid/unsupported input, never a clean bill of health.
  Audit uncompressed output before Draco/meshopt and inspect the compressed
  consumer separately. It does not validate winding, source solids, intersections,
  node-transformed placement, runtime draw calls or gameplay. Keep source meshes
  for topology/volume inspection; check transformed instance bounds in-game.
  The harbour correction's own empty issues list missed 16 zero-area triangles.

- **Rigged-asset rejection gates** (block the asset before it reaches a build; each one is a
  known failure class):
  - a character MAIN model still contains swappable gear (gear is separate parts on sockets);
  - action/animation files carry duplicate render meshes;
  - skeletons or bone names differ across actions of the same character;
  - a required role, socket (`target`, `ground`, `vfx-hit`, `vfx-death`, `attack-*`), collider,
    equipment-slot declaration or provenance field is absent;
  - toggling gear leaves visible fragments or holes without a declared underlayer boundary;
  - an attack animation has no authoritative timing and collision contract (see
    `_game-kit/core/ENEMY-CONTRACT.md`);
  - status language is truthful: `catalog-only` (recorded), `review-only` (inspector exists),
    `runtime` (gameplay loads it). Only `runtime` counts as shipped.
  Mechanical half: `audit_glb.py --rig --require-sockets target,ground,vfx-hit,vfx-death` reports
  skins, joint names, duplicate primitives (identical geometry buffers) and missing named nodes.
  Design after MengTo/Skills build-rigged-game-assets requirements (MIT); the human half stays a
  checklist.
- **Tone stats**: percentile clipping, e.g. "0.00% of pixels clip and the
  99th percentile is 165" — actionable; "looks flat" is not.
- **Contact sheets**: render every set-piece/angle into one grid image,
  judge the set at once rather than one screenshot at a time.
- **Clay check before any bake is trusted**: flat grey, hard key + rim +
  bounce, no textures, no emissives. A silhouette reading as a rectangle or
  an edge reading as infinitely sharp means the model isn't finished —
  textures and lighting hide box-stacking completely, flat clay does not.
- **Re-verify the capture isn't stale**: if the render/dev surface can
  hot-reload mid-capture, re-check the expected state is actually showing
  before saving, restart if not — a loading-state screenshot with a
  plausible number next to it is a silent false pass.
- **Draw-call and fps survey** after adding any asset: report draw count
  against the pre-change baseline (join-per-material should hold it flat)
  and frame time on the heaviest scene the asset appears in.
- **AO sanity**: print the raw bake's percentile spread (1st/10th/50th/90th)
  before floor-lifting — `min == 0` over a large area means winding or
  distance is wrong, not that floor-lift will fix it.
- Numbers not yet measured on gex44/RTX 4000 Ada (draft/final render time,
  bake time for a 4096 atlas): **unmeasured** — get one real run's numbers
  before writing them into a plan or a budget.

# Blender game assets, headless

Distilled from TheLongSilence's Blender pipeline (162 m ship, carved rocks, a
cabin interior kit, 13 ground materials) into a headless-first recipe for
Forge. **No GUI, no BlenderMCP socket** — Forge's Blender lives on gex44 with
no display, and `blender -b` is the one thing BlenderMCP's addon refuses to
run under. Everything below is a plain `blender -b --python` call or the
gex44 exec service.

For architectural construction kits, read `construction-kit` and its tested
source builders. It supplies cross-family profile/damage/UV contracts and
consumer-side checks; use only the relevant elements.

For a connected playable scene, also read `visual-game-loop` and its
`references/whole-scene-blender.md`: the user-approved harbour recipe combines
scene/object references, photographic materials and coherent Blender construction
with gameplay verification. Reuse good hero assets; author the surrounding place
as a whole rather than assuming a larger modular catalog will fix assembly.

## Read only what the task needs

| When | Read |
| --- | --- |
| A dense model must become a light one that keeps its look (normal + AO transfer) | [high-to-low baking](reference/high-to-low-baking.md) |
| Preparing UVs or a cage, or a bake shows seams, black faces, wrong highlights | [baking and diagnostics](reference/baking-and-diagnostics.md) |
| Choosing texture or mesh formats, or the asset is slow to load or heavy in GPU memory (KTX2, WebP, meshopt, Draco) | [asset delivery](reference/asset-delivery.md) |
| Before any long bake or scripted export pipeline | [preflight and recovery](reference/preflight-and-recovery.md) |
| The asset looks right in Blender and wrong in the game, or the cause could be either | [runtime parity and diagnostics](reference/runtime-parity-and-diagnostics.md) |
| The asset will be judged by eye (hero prop, character, building, environment) | [author and critic loop](reference/critic-loop.md) |
| Terrain, cliffs or rocks should look weathered (branching gullies and ridges, no simulation) | [terrain erosion](reference/terrain-erosion.md) |

These seven are loaded on demand, not by default. Five are ported from vercel-labs/vgpu (see Attribution); terrain erosion uses Rune Skovbo Johansen's filter (MPL 2.0, `scripts/erosion/`).

### Choose how to carry each detail before any bake

| Detail | Carry it as |
| --- | --- |
| Silhouette, openings, broad edges, tuft dimples, piping, moving parts | Real low-poly geometry |
| Fine bevel curvature and shallow relief the triangle budget cannot afford | Tangent-space normals baked from the dense source |
| Permanent cavities and contacts inside a rigid assembly | Baked AO |
| Fabric weave, grain, micro-texture | The existing tiled map at its own scale, never re-baked into a unique atlas |
| Contacts that change, directional shadows | Runtime lighting |

**Pick the cheapest carrier that passes the look check. Being under a texture budget is not a reason to
spend it.** A unique normal atlas is the last resort, for detail the triangle budget cannot hold: a
1024 px RGBA8 map with mips is 5.6 MB of GPU memory per asset, and it replaces a tiled map that every
copy of the material could have shared. If you try a bake and geometry plus the source's tiled maps
looks as good, ship the geometry and say so in the report.

Measured (2 Oct 2026, STRANDMON armchair, 233k to 12k triangles, two Astra runs, same brief): dimples kept
as geometry with the two original 256 px tiled maps = 0.46 MB download, 0.7 MB GPU textures. Same detail
baked into a unique 1152 px normal map = 1.19 MB download, 7.4 MB GPU textures, slightly closer from across
the room, slightly weaker up close, and a blind judge preferred the geometry version.

## Which representation: decide before modelling

For furniture reconstructed from photographs, datasheets or assembly instructions,
read [Furniture reconstruction checks](reference/furniture-reconstruction.md)
before generating geometry. It covers panel-relative coat-hook placement,
interior compartment counts and optional door/drawer articulation.

| Need | Representation | Why |
| --- | --- | --- |
| Hero or enemy character with a walk and attacks | imported rigged mesh (this skill, or the CC0 library: Quaternius, KayKit, Mixamo motions) | skinning, retargetable clips; procedural rigs read as mannequins |
| Weapon, prop, creature variant where silhouette, sockets, collision or code-driven variants matter | procedural three.js geometry or a small GLB kit part | controllable, cheap to vary per instance |
| Concept, icon, backdrop, card art | a generated 2D image used directly | never rebuilt as geometry |
| A reference image whose visible FORM must become a code model | `img2threejs` with its gates; say the result is a reconstruction, not extracted geometry | likeness is judged, not measured |

Pick once at the blueprint or stack-selection stage and record it with provenance (source, licence,
metres per unit, forward axis). Design after MengTo/Skills build-hybrid-game-assets (MIT).

## 1. The recipe

The concept image is the spec, not decoration. For every asset in a kit:

1. **Model every piece in Blender from the concept image** using loft/recess/
   greeble (§3). Grey-clay render it before touching a texture (§4, §10) —
   box-stacking hides under any lighting rig except flat grey + one hard key.
2. **Use a fitting registered photographic texture set or an image model** for
   photographic surfaces (ground, foliage, cloth). Record origin, license and
   physical scale; matching normal/roughness maps must remain aligned. Use an
   existing suitable licensed scan before generating a replacement; use Cycles nodes only for what
   genuinely varies by geometry (edge wear, per-plate tone), and flatten
   before export (§6).
3. **Screenshot-vs-concept loop.** Render next to the concept, same angle if
   possible, compare. Judge by measured numbers where you can (§10: tone
   percentiles, AO floor, draw calls), by eye where you can't (silhouette,
   chamfer read, material believability). Iterate until it reads as the
   concept, not until it "looks 3D".
4. **Export once clay AND texture both hold up.** A model that's flat-correct
   in clay but goes muddy after baking has a material bug, not a modelling
   bug — don't re-model to fix a bad bake.

## 2. Headless setup on gex44

Blender 5.2.0 LTS, x64, RTX 4000 Ada, at
`/root/blender-spike/blender-5.2.0-linux-x64/blender`.

**A. Direct subprocess** (matches the source game's `build_*.py` pattern):
```python
BLENDER = "/root/blender-spike/blender-5.2.0-linux-x64/blender"
cmd = [BLENDER, "--background", "--factory-startup", "--python-exit-code", "1", "--python", __file__,
       "--", "BUILD"] + extra_args
# script: `if 'BUILD' in sys.argv: blender_main(...)` else `drive(...)`
```
Split into `drive()` (host: subprocess + result check) and `blender_main()`
(only imports `bpy`/`bmesh` — importing them outside `-b` crashes with no
display). **Without `--python-exit-code 1`, Blender can exit 0 after a Python error.**
Set that flag, check the exit code and logs, and verify fresh output files.
Mesh/export validation still matters: a successful process is not visual proof.

**B. gex44 exec service** (`/opt/astra-blender/blender_exec_server.py`,
loopback `:8793`, token-guarded): POST a python script, get back stdout plus
render paths, for interactive iteration without a subprocess per call. Same
headless constraint — the script is a `blender_main`-shaped body, no GUI code.

Outputs land in the app's `public/models/` (or the GameKit pack's asset dir)
as `.glb` + `.webp`. Draft render: 64 samples / 1280x720 ≈ 2 s on an M-series
GPU (source game, Apple Silicon) — **gex44/RTX 4000 Ada timing is
unmeasured; get one real number before quoting a render budget.**

## 3. Modelling: loft, recess, greeble

Three techniques, in order of impact.

**Loft cross-sections, never stack primitives.**
```python
def oct_ring(w, h, cx, cz):
    a, b = w * 0.5, h * 0.5
    return [( a, b-cz), ( a-cx,  b), (-(a-cx),  b), (-a,  b-cz),
            (-a, -(b-cz)), (-(a-cx), -b), ( a-cx, -b), ( a, -(b-cz))]

def loft(name, sections, mat):    # sections: (y, w, h, cx, cz, dz)
    bm = bmesh.new()
    rings = [[bm.verts.new((x, y, z+dz)) for (x, z) in oct_ring(w, h, cx, cz)]
             for (y, w, h, cx, cz, dz) in sections]
    for A, B in zip(rings, rings[1:]):
        for i in range(8):
            j = (i+1) % 8
            bm.faces.new((A[i], A[j], B[j], B[i]))
    bm.faces.new(list(reversed(rings[0]))); bm.faces.new(rings[-1])
```
Keep the profile **stepped, not tapered** — a parallel midbody, a shoulder, a
blunt end. Steps are what the eye measures scale against.

**Cut detail into the skin**, not glued on top:
```python
sel = [f for f in bm.faces if pick(f)]
bmesh.ops.inset_region(bm, faces=sel, thickness=1.2, depth=0.0,
                       use_even_offset=True, use_boundary=True)
for f in sel:
    bmesh.ops.translate(bm, verts=list(f.verts), vec=f.normal.normalized()*-0.7)
    f.material_index = i_recess
```

**Detail hierarchy, including restraint.** Primary masses, panel bays, fine
greebles at roughly **1/60 of the asset's longest dimension**. Zone them and
**leave clean plate** — greebling every face reads as noise; detail only
registers against something undetailed. Flat-shade hard surfaces.

**A Bevel modifier does nothing on face-soup geometry** — bmesh ops emit
every face with fresh vertices, no shared edges to bevel. Weld first, then
chamfer:
```python
def weld_bevel(ob, width=0.0025, segments=2, angle=math.radians(31), dist=2e-5):
    me = ob.data
    bm = bmesh.new(); bm.from_mesh(me)
    bmesh.ops.remove_doubles(bm, verts=bm.verts, dist=dist)   # joins coincident boxes
    bm.to_mesh(me); bm.free(); me.update()
    apply_bevel(ob, width=width, segments=segments, angle=angle)
```
A 90-degree edge returns no highlight from any light — the single largest
thing separating "modelled" from "a pile of boxes". `o.scale = size` then
Bevel makes pillows (Bevel is local-space) — `transform_apply(scale=True)`
before bevelling.

## 4. Kit-bake pipeline (interior_bake/ distilled)

For a repeated kit (a corridor, a room set, a prop family), stage the build
so nothing bakes twice and occlusion bakes into the placement it ships in:

1. **Tile geo** — hi-poly tile (plates, rivets, hatches) as a **3x3 array**
   so only the centre tile bakes and its edges see real neighbours (no
   cross-fade). Panel tile 2.0 m, deck tile 1.5 m in the source kit.
2. **Tile bake** — bake **height by ray-tracing an Emission shader whose
   colour is world-Z**, not a tangent-space NORMAL bake off a flat cage: a
   vertical panel-gap wall has no cross-section for a downward ray, so a
   NORMAL bake off a plane records nothing for it. Height + a prefilter gives
   both the seams and a slope a texel wide.
   ```python
   sc.render.bake.use_selected_to_active = True   # hi -> flat lo plane
   sc.render.bake.cage_extrusion = 0.05
   ```
3. **Compose** (numpy) — prefiltered normal from height (clamp depth *before*
   differentiating: an undamped 26 mm slot over two texels is a normal lying
   flat, rendering as a crawling black slit); crown/cavity masks drive wear
   and grime; procedural stencils (part numbers, hazard stripes) into albedo.
4. **Kit** — parametric part builders on a shared profile/loft/box library
   (`Part`-style primitives, per-edge bevel, a material "slot" tag).
5. **Props / assemble** — instantiate every master once, `weld_bevel` each
   with a **hand-tuned width per part class** (finer on small props — a
   2.5 mm round-over eats a 6 mm book board), lay the kit out at its in-game
   transforms *before* baking so occlusion matches what ships.
6. **UV + AO bake**:
   ```python
   def unwrap_and_pack(masters, res=2048):
       for ob in masters.values():   # per-object smart UV project, then:
           ...
       bpy.ops.uv.average_islands_scale()
       bpy.ops.uv.pack_islands(margin=0.006, rotate=True)

   def bake_kit_ao(masters, occ, res=2048, dist=1.5, samples=128):
       sc.cycles.samples = samples
       # AO node -> Emission -> Material Output, per material, bake EMIT
   ```
   **AO bakes along the surface normal — wind kit-hull skin facing INTO the
   room**, or it bakes unoccluded everywhere (open space). **Floor-lift the
   result** — occlusion is a modulation, not a shadow; anything reaching
   pure 0 paints a black line lighting can never recover
   (`a2 = 0.34 + 0.66*a**0.85`).
7. **Clay check** before any texture or bake is trusted (§10).

**Texel density**: panel shipped 2048 px / 2.0 m = **1024 px/m**; deck
1024 px / 1.5 m = **683 px/m**; the interior kit's UV/AO atlas ran at
**4096 px** (the bake function's own default is 2048 — override per project,
don't trust a library default). Pick texel density from viewing distance: a
corridor the player's shoulder passes within 40 cm of needs more than a
ceiling never seen close.

## 5. Rocks and foliage

**Rocks** (`build_rocks.py`): carve, don't deform a sphere — a deformed
icosphere is convex-ish every time (the "potatoes" problem). Instead: dense
icosphere → `bmesh.ops.bisect_plane(..., clear_outer=True)` several times for
fracture faces (family-dependent: slab/block/boulder/column/shard) → smaller
bisects near corners for chips → two octaves of `mathutils.noise.noise`
displacement along the normal → `REMESH` (voxel) to heal cuts into one
manifold → `DECIMATE` to a triangle budget → `shade_smooth_by_angle` so
fracture edges stay sharp → bake AO to a `BYTE_COLOR` vertex attribute
(spread instances apart *before* baking — stacked at the origin they occlude
each other into a mean of 0.2) → normalise so the longest axis is 1 and the
low point sits at 0. Ship **8-11 variants across 3 LODs** (full, ~500 tri,
~160 tri) in one GLB, `export_vertex_color='ACTIVE'`, no materials — AO rides
in `COLOR_0`, the shader supplies the surface.

**Foliage** (`pack_leaf.py`): pack an image-model leaf-cluster cutout (RGBA,
transparent bg) into a 512x512 lossless atlas. Normalise each RGB channel's
mean over opaque pixels to 0.5, so the image contributes *variation about the
palette* rather than its own green. Dilate outward into the transparent
margin — bilinear alpha filtering averages the last opaque texel with its
transparent neighbour, and a black neighbour puts a dark fringe on every
edge. Ten dilation passes covers a 512-texel margin at any mip seen.

## 6. Materials

**Procedural (Cycles-only, geometry-driven):** per-plate tonal variation +
pointiness edge wear, the two nodes that make paint look built:
```python
vor = nt.nodes.new("ShaderNodeTexVoronoi"); vor.inputs["Scale"].default_value = 0.16
# RGBToBW -> MapRange 0.9-1.1 -> Multiply into base colour: plate batches
# never quite match, and that mismatch is most of what reads as "welded".
geo = nt.nodes.new("ShaderNodeNewGeometry")
pr = nt.nodes.new("ShaderNodeMapRange")   # From 0.49-0.56, clamp, -> wear factor
nt.links.new(geo.outputs["Pointiness"], pr.inputs["Value"])
# mix toward bare metal + drive Metallic up: free on every convex corner,
# exactly where paint goes in life.
```
Also: bleach on sun-facing normals (`dot(Normal, sun_dir)`), soot along an
object-space axis. **These do NOT survive glTF export** — three.js never
sees the node graph. Bake to a texture before export, or export flat base
colours per material bucket and let the app's own shader apply bleach/soot
from world position (what the source game does).

**Image-model derived** (ground, cloth, rock faces): one generated albedo is
the only photographic input, everything else *derived* in numpy so it can't
disagree with it:
- `height_from_albedo` — 3 band-passed luminance scales (fine/mid/coarse),
  weighted toward the middle — "dark is deep" is the prior every
  albedo-to-normal tool uses and it holds for ground.
- `normal_from_height` — central difference of the height field.
- `ao_from_height` — horizon-based, 16 directions, cone-stepped march.
- `roughness_heuristic` — dust in cavities (rough), exposed faces polish
  (less rough), clamped to an art-direction matte floor.
- **Seam fix in the gradient domain**, not by blending pixel values: take the
  gradient, force it periodic across the wrap by killing the seam's jump
  over a margin of a few px (weight ramps 0→1 away from the seam), then
  FFT-Poisson-integrate back. Mismatch lands in the lowest-frequency mode
  (an invisible ramp) instead of a visible strip at the border — a wide
  margin instead draws bright bars through the derived occlusion.

An image model asked to paint colour onto a rendered height map **redraws
the geometry** (measured: same style, every stone somewhere else). Asked to
*colourise* a flat, shading-free render of the SAME image, it keeps every
stone in place — colourise, don't paint-over, when height must register to
albedo.

## 7. Lighting and camera

**Void/hero lighting**: one hard key (`SUN`, angle ≈ 0.9°), a large weak
fill tinted toward the key's complement, a cold rim so nothing dissolves
into the background. Shadows never fully black. **Camera on the key side** —
a hero angle from the shadow side is carried by fill and reads washed out.

**Clay/QA lighting** (three `SUN`s: key, rim, bounce from below) — the
bounce matters because half of any interior's surfaces face down (an
overhead console, a coaming's underside) and key+rim alone renders them as
unreadable black.

**Camera from the bounding box, never by hand** — hand-placed cameras end up
inside geometry, costing **80x render time** (near-field bounces: 166 s vs
2 s measured):
```python
pts = [o.matrix_world @ Vector(c) for o in meshes for c in o.bound_box]
lo = Vector((min(p[i] for p in pts) for i in range(3)))
hi = Vector((max(p[i] for p in pts) for i in range(3)))
ctr = (lo + hi) / 2; rad = max((p - ctr).length for p in pts)
cam.location = ctr + direction * (rad / math.tan(cam.data.angle / 2) * 1.05)
cam.rotation_euler = (ctr - cam.location).to_track_quat("-Z", "Y").to_euler()
```
`to_track_quat` assumes Z-up world; if the asset is authored Y-up inside
Blender's Z-up slots, build the look-at basis by hand (cross products off
the target vector and the game's own up axis) or every render is on its side.

**Voronoi stars, never thresholded noise** — noise can't separate density
from size (raise frequency to shrink points → thousands; widen the band to
brighten → falling snow). Voronoi: cell scale = how many, distance threshold
= how big. Cells over a sphere ≈ `4π·scale²`, a frame sees under 1% of it, so
`scale=30` puts ~15 cells in shot — use `scale ≈ 110`. Angular radius =
`threshold / scale`; move both together.

**Backdrop geometry must be camera-visible only.** A large emissive shell
(planet, skybox) hit by diffuse/glossy rays becomes an area light every
shading point importance-samples — measured **145 s → 4.3 s**:
```python
for o in (planet, atmo):
    o.visible_diffuse = o.visible_glossy = o.visible_transmission = False
    o.visible_volume_scatter = o.visible_shadow = False
```

## 8. Export contract for three.js

- **Join per material within each rigid assembly before export.** Keep moving
  doors/drawers, their attachment groups and required named parts separate;
  never merge them into the static carcass just because they share paint.
  One Blender object = one glTF node =
  one draw call. A loose 11-material ship export was 78 draws;
  `bpy.ops.object.join()` per material group brought it to ~11.
- **Metres, Y-up**: `bpy.ops.export_scene.gltf(export_format='GLB',
  use_selection=True, export_apply=True, export_yup=True)`. (The source game
  exports `export_yup=False` because its own runtime is Y-up-in-Blender's-
  Z-up-slots by convention — a plain three.js consumer wants `export_yup=True`.)
- **Flat base colours or baked textures only** — procedural nodes don't
  survive the round trip (§6). `KHR_materials_emissive_strength` DOES
  survive — nav lights, emissive panels keep authored intensity.
- **Draco for real triangle counts**: position 14-bit quantization is ~1 mm
  over a 16 m interior (a tenth of the smallest chamfer), normal 10-bit,
  texcoord 12-bit, compression level 6.
- **WebP out of Blender directly is lossless regardless of the quality
  argument** — its own quality slider is silently ignored. PNG-dump from
  Blender, encode to WebP with PIL on the host if you need real lossy quality.
- **Check draw calls after adding anything** — a duplicated kit piece is one
  draw call against a shared mesh no matter how many times placed; a fresh
  join is not.

## 8b. Destructible vehicles (tank-damage/v1, 11 Oct 2026)

22 library tanks were made destructible by Astra-directed Blender jobs; the contract and pipeline live in forge-assets
`TANK-DAMAGE.md` (job writer `tools/vehicles/make_jobs_tanks2.py`, retrofit `make_jobs_tanks_retrofit.py`).
- TWO GLBs in the same frame: A = healthy, every bolt-on item its own `Part_<Name>` node (complete surface underneath, origin
  at its centre), `Barrel` child of `Gun`, `Muzzle` child of `Barrel` (identity rotation), `Fx_*` empties; B = damage only:
  `Hull_Damage` (`Dmg_` twins at their Part origins, `Scar_<face>` hit marks 2-4 mm proud, `Track_L/R_Broken`),
  `Turret_Damage` at the Turret origin (`Dmg_Turret_*`, `Scar_Turret_*`, `Gun_Broken` at the Gun origin), `Wreck_Hull`
  (material `Burnt`), `Wreck_Turret` with a closed underside. One file would draw wreck + healthy together (no hidden flag in glTF).
- Build the damage from COPIES of the healthy meshes (deform, cut, boolean, decimate) so everything lines up; the job renders
  `states.png` (healthy, hit, stripped, immobilised, wreck, turret off) from the two exported GLBs and looks at it.
- Retrofit an existing model from its previous build script + GLB + baked textures (copy them into a NEW remote dir): the
  offsets stay, so games aim the same way. Check the Muzzle position afterwards (the old Sherman's pointed backwards).
- Six to eight jobs at once worked (healthy file in 10-30 min, damage by ~60, 47-60 min in all; GPU gate on gex44).
  Each writes 50-105 MB into `~/.codex/sessions`: watch the local disk.
- A library card version is immutable: the importer refuses a version that belongs to another job.
- In game the model wants the runtime skin (FGE `module/vehicle-skin.mjs`, the JUGGERNAUT technique) on top of its bake.

## 9. Traps

- Bevel on bmesh-authored geometry does nothing (no shared edges) — weld
  first (§3). `o.scale` then Bevel makes pillows — apply scale first.
- `matrix_parent_inverse = parent.matrix_world.inverted()` cancels the
  parent transform (the "keep transform" idiom). Leave it at identity for
  the child to inherit the parent's rotation.
- A rotation about the wrong axis silently does nothing visible — a panel
  whose normal is +X doesn't change facing when rotated about X. Measure the
  world normal against the view vector rather than reasoning about it.
- Map Range with `To Min > To Max` and clamp on collapses to zero (clamps to
  an inverted interval) — invert with a `SUBTRACT` node instead.
- A Mix node in RGBA mode can silently drop a branch — several sockets share
  the name "Factor". Combine world contributions with two `Background` nodes
  into an `Add Shader` instead.
- The image preview downsamples — 4-px stars average away in a 1080p
  preview. Crop 1:1 and count bright pixels before concluding nothing rendered.
- A tangent-space NORMAL bake off a flat plane records nothing for vertical
  geometry — bake height by ray-traced Emission instead (§4).
- AO bakes along the surface normal — a kit skin wound facing away from the
  room bakes unoccluded everywhere.
- An AO map reaching pure black paints an unrecoverable dark line —
  floor-lift it (§4).
- Blender's WebP writer ignores its own quality setting, always lossless —
  PNG-dump and re-encode on the host (§8).
- Blender exits 0 even when the driven script raised — check stderr and the
  output file, not the return code (§2).
- A socket/exec service keeps Blender's *process* environment between calls
  — a default from a stale env var silently sends output into the wrong
  checkout. Assign output paths explicitly every call, never `setdefault`.

**Blender 5.x API changes** (4.x code fails on all of these):
- `Scene.node_tree` gone → `Scene.compositing_node_group`;
  `CompositorNodeComposite` no longer exists — the group's output socket IS
  the result.
- **The compositing group must contain a `CompositorNodeRLayers`.** Feeding
  it only from a Group Input means nothing depends on the render, so Blender
  skips rendering and writes a transparent black frame in 0.1 s. A
  suspiciously fast render is this bug.
- `Action.fcurves` is gone (slotted actions). Set
  `context.preferences.edit.keyframe_new_interpolation_type` *before*
  inserting keys.
- Glare/Lensdist settings moved from properties onto **sockets**; enums take
  display names (`"Fog Glow"`, `"Streaks"`, `"High"`), not old identifiers.
- Legacy addons still install to `~/Library/.../Blender/<ver>/scripts/addons/`
  on macOS — irrelevant on gex44, relevant for local proving.

## 10. Gates (measurable, not "looks right")

- **Independent export audit**: run
  `python3 scripts/audit_glb.py /absolute/path/asset.glb --strict` from this skill
  directory (requires numpy). It reports mesh-local triangles, nonfinite values,
  degenerate triangles, material groups and texture portability. Exit 1 means
  findings; exit 2 means invalid/unsupported input, never a clean bill of health.
  Audit uncompressed output before Draco/meshopt and inspect the compressed
  consumer separately. It does not validate winding, source solids, intersections,
  node-transformed placement, runtime draw calls or gameplay. Keep source meshes
  for topology/volume inspection; check transformed instance bounds in-game.
  The harbour correction's own empty issues list missed 16 zero-area triangles.

- **Rigged-asset rejection gates** (block the asset before it reaches a build; each one is a
  known failure class):
  - a character MAIN model still contains swappable gear (gear is separate parts on sockets);
  - action/animation files carry duplicate render meshes;
  - skeletons or bone names differ across actions of the same character;
  - a required role, socket (`target`, `ground`, `vfx-hit`, `vfx-death`, `attack-*`), collider,
    equipment-slot declaration or provenance field is absent;
  - toggling gear leaves visible fragments or holes without a declared underlayer boundary;
  - an attack animation has no authoritative timing and collision contract (see
    `_game-kit/core/ENEMY-CONTRACT.md`);
  - status language is truthful: `catalog-only` (recorded), `review-only` (inspector exists),
    `runtime` (gameplay loads it). Only `runtime` counts as shipped.
  Mechanical half: `audit_glb.py --rig --require-sockets target,ground,vfx-hit,vfx-death` reports
  skins, joint names, duplicate primitives (identical geometry buffers) and missing named nodes.
  Design after MengTo/Skills build-rigged-game-assets requirements (MIT); the human half stays a
  checklist.
- **Tone stats**: percentile clipping, e.g. "0.00% of pixels clip and the
  99th percentile is 165" — actionable; "looks flat" is not.
- **Contact sheets**: render every set-piece/angle into one grid image,
  judge the set at once rather than one screenshot at a time.
- **Clay check before any bake is trusted**: flat grey, hard key + rim +
  bounce, no textures, no emissives. A silhouette reading as a rectangle or
  an edge reading as infinitely sharp means the model isn't finished —
  textures and lighting hide box-stacking completely, flat clay does not.
- **Re-verify the capture isn't stale**: if the render/dev surface can
  hot-reload mid-capture, re-check the expected state is actually showing
  before saving, restart if not — a loading-state screenshot with a
  plausible number next to it is a silent false pass.
- **Draw-call and fps survey** after adding any asset: report draw count
  against the pre-change baseline (join-per-material should hold it flat)
  and frame time on the heaviest scene the asset appears in.
- **AO sanity**: print the raw bake's percentile spread (1st/10th/50th/90th)
  before floor-lifting — `min == 0` over a large area means winding or
  distance is wrong, not that floor-lift will fix it.
- Numbers not yet measured on gex44/RTX 4000 Ada (draft/final render time,
  bake time for a 4096 atlas): **unmeasured** — get one real run's numbers
  before writing them into a plan or a budget.

# Preflight and Recovery

Use this workflow for long bakes and scripted asset delivery. Keep a short manual edit lightweight; add checkpoints where repeating expensive work or confusing stale output is a real risk. These are asset execution requirements, independent of how many people or agents perform the work.

## Exercise the actual execution path first

Before an expensive run, provide and run a task-local preflight command using the same executable, working directory, dependency environment and helper paths as the intended run. Reuse existing project checks where possible. A version query or import from another directory is not an execution probe.

- Start native Blender (gex44 path and GPU gate wrapper: `SKILL.md` §2) and execute a minimal scene operation through Python. For scripted runs, use `--python-exit-code 1`; inspect logs and the expected output, not exit status alone.
- Exercise the chosen render/bake device with a tiny representative bake, then export, encode/decode and import a small fixture through the actual exporter and runtime loader. Await codec initialization. Resolve copied Node helpers from their real execution directory and module mode; a successful ESM import does not establish that a copied CommonJS helper can resolve its dependencies.
- Classify required and optional inputs before baking. Verify required files, codecs, writable output paths and capture dependencies. Missing optional metadata must have a documented fallback or be omitted deliberately, not fail final assembly after a completed bake.
- Capture and read one real target-renderer frame with the intended browser/image tools. Record the actual backend; a fallback renderer does not validate the requested backend. This probe establishes that the tools work, not final visual quality.

If a probe fails, fix or report that boundary before starting dependent expensive work. Do not keep retrying the unchanged failure. If sources may change during a run, execute an immutable snapshot including local imports; record external dependencies and verify snapshot hashes at completion.

## Keep stages independently recoverable

Give expensive stages explicit commands, inputs, outputs and validation. A task-local script may expose subcommands or separate entry points; no particular build framework is required. Do not force a bake when that asset does not need one.

| Stage | Evidence needed before its outputs can be reused |
| --- | --- |
| Prepare | Saved source/LOW checkpoint, resolved transforms and reproducible parameters |
| Validate geometry | Openings, contacts, normals and UV checks on evaluated/exported LOW; simple-material views, including relevant LODs |
| Bake | Lossless masters, actual pass settings and dependency identities, coverage and representative pixel checks |
| Export | Decodable serialized meshes, map/UV bindings and measured counts; reconcile exporter changes with prepared geometry |
| Package | Required files, decoded texture error, channels/mips and delivery manifest with hashes |
| Verify runtime | Actual target-backend captures from matched cameras, independent map toggles, measured costs and renderer errors |

For each attempt, save the exact command, input/dependency hashes, tool identities, exit outcome, output hashes, validation results and failure reason. Mark a stage complete only after its outputs pass its checks. Keep failed attempts and logs distinct from completed checkpoints. File existence or a successful process alone is not proof of completion.

On retry, start at the earliest invalid stage and revalidate dependent outputs. If packaging fails after a verified bake/export, resume packaging from those artifacts; do not regenerate the scene merely to rerun a copy step. When geometry, normals or lighting change, use the [bake dependency rules](baking-and-diagnostics.md#reuse-bakes-by-their-dependencies) to decide which passes need new identities.

## Validate a candidate before replacing delivery assets

Keep candidate assets separate from the last working delivery. Verify the candidate manifest and served build/asset identities before capture; avoid a preview that silently loads missing files from the old asset set. Promote only the validated files together with their matching manifest, retain a recoverable previous version, and smoke-check the delivered URL after replacement. Report whether the replacement is atomic; per-file writes do not make the whole asset set atomic.

Checks establish structural and runtime evidence, not aesthetic acceptance. Pair them with the matched visual review in [the critic loop](critic-loop.md) and the gates in `SKILL.md` §10.

# Author and critic loop for a Blender asset

Use this for any authored asset that will be judged by eye: a hero prop, a character, a building, an
environment. Skip it for a mechanical re-export.

## Seats

| Seat | Who | Owns |
| --- | --- | --- |
| Author | Astra (operator law: Blender work goes to Astra) | Geometry, authored materials, UVs, bakes, Blender renders, the export |
| Runtime | The root, or one worker when the shader work is real | Loading the export in the game's actual three.js path, captures, measured costs |
| Critic | A different model family from the author, reading the real images | Findings only. Never edits the asset |

The critic must open the actual capture files. A critic that cannot read images says so and returns
BLOCKED; it never writes a visual verdict from metrics or from the author's description.

## Budget

- Default: **3 revisions, at most 2 critic passes per revision.** The brief may set another cap.
- A cap is an execution limit, not acceptance. Cap reached with open visual findings = `REVISE`
  reported as such, never a `PASS`.
- No unattended improvement loop past the cap.

## Before the first render

Write in the task folder: scope, target cameras (gameplay view, hero, rear, closest required view),
output paths, budgets (triangles, exported vertices, texture bytes and GPU memory, draw calls) and
the revision cap. Budgets are task inputs; do not copy another asset's numbers.

Run the [preflight](preflight-and-recovery.md) once: Blender starts and runs a scene operation, a
tiny bake and export round-trips through the real loader, one real runtime frame is captured.

Integrate a cheap LOW blockout in the runtime at this stage. Scale, axis, camera and material
contract problems are found before an expensive bake, not after.

## Each revision keeps

- the source revision or parameters that rebuild the previous asset;
- real hero, rear and close-up captures, same camera, light, exposure and pose every time;
- triangles, exported vertices, primitives, material count, file bytes, texture GPU memory;
- runtime draw counters, kept apart from offline estimates;
- the critic's findings, the fixes chosen, and the next measured result.

## The critic pass

The critic receives the previous AND the current captures and metrics under matched cameras (or
an explicit "first revision, no baseline"), the reference image, and the brief. It returns:

- **at most five findings**, ordered by impact, each with a stable id, the evidence path (whole
  view plus crop or image coordinates), the visible symptom, a suggested correction and a
  **measurable acceptance condition**;
- regressions against the previous revision;
- resolved / remaining / regressed status of earlier findings on a follow-up pass;
- `PASS`, `REVISE` or `BLOCKED`, with the limits of its evidence.

It compares against the reference as well as the previous revision: clean topology and progress
since last time do not make the asset match the reference. It separates the observed defect from
the suspected cause. A small whole-image difference can hide severe local damage (thin trim,
stairs, silhouette edges): it inspects crops at each delivered LOD. Design ideas are suggestions,
not new acceptance requirements.

When the cause could be the asset or the renderer, it asks for the diagnostic captures in
[runtime parity](runtime-parity-and-diagnostics.md) (maps off, AO neutral, lightmap off) rather
than guessing.

## Rules that stop false passes

- A generated concept image is never proof of a working model. Label concepts as concepts; accept
  only on real renders of the real export.
- Requested bakes need bake provenance (what was baked, from what, at what settings) and matched
  runtime captures with each contribution switched off in turn. Vertex tint and runtime shadows
  are not substitutes for a requested AO or lightmap bake.
- An atlas repair is checked on the full matched views, not only on the crop that was broken: a new
  layout can fix one edge and turn another face black.
- One writer per handoff file. A reply never gets appended to a request file another agent will
  regenerate. Superseded manifests and failed captures stay on disk.
- The author hands the root a compact result: verdict, the few decisive images, the metrics table.
  Full capture sets stay on disk; the root does not load every image.
- A user's rejection or a changed brief reopens any earlier `PASS`.

## Lessons

When a revision teaches something that will recur, write it as: evidence path, symptom, cause,
intervention, matched before/after result, scope. The root checks it and makes a narrow edit to this
skill. Reject task-specific style preferences dressed up as general rules.

The first renders show the overall shape, but they also exposed details to fix: the side trim sits too far from the skin, the headlamps look raised, and the intake openings need more depth. The mesh is also over budget at 120k triangles, so I’m reducing redundant subdivisions while making those corrections.

In `sheet.jpg`, the lower body curves downward to form pronounced front and rear repulsor fender blisters (`x=380..660` and `x=1130..1410`), tucks upward along the mid-door rocker sill (`x=680..1100, y=335..375`), and sweeps steeply up behind the rear repulsor (`x=1390..1540`). In `final1.png` and `rear1.png`, the sides are slab-flat in plan view rather than pinching inward at the doors between flared front and rear arches. | Remove the lower sill pipe; sculpt rounded downward fender blisters over the front and rear repulsors; raise and undercut the mid-door rocker sill between the arches; sweep the rear lower quarter upward toward the diffuser; add plan-view coke-bottle fender flares (`2.2 m` width at arches tapering to `~1.95 m` across the door waist). | In `side1.png`, the mid-door rocker sill sits `0.08 m to 0.12 m` above the lowest tangent of the front and rear repulsor fender blisters, the rear lower quarter sweeps up at `20\u00b0 to 28\u00b0` behind the rear repulsor, the extra bottom sill pipe is gone, and 3/4 views show distinct front and rear fender flares around a pinched door waist. |\n| **F3** | **P1** (High) | [sheet.jpg](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/sheet.jpg): side repulsors `x=445..635, y=365..430` (`0.16..0.23, 0.24..0.28`) & `x=1180..1375, y=350..430` (`0.43..0.50, 0.23..0.28`), front/rear `x=165..635, y=815..860` (`0.06..0.23, 0.53..0.56`)<br>[side1.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/side1.png): `x=450..615, y=655..745` (`0.23..0.32, 0.61..0.69`) & `x=1310..1480, y=655..745` (`0.68..0.77, 0.61..0.69`)<br>[final1.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/final1.png): `x=870..1000, y=830..920` (`0.45..0.52, 0.77..0.85`) | **Dangling cog-wheel repulsor barrels on stalks vs tucked saucer pads:** Repulsors are modeled as tall vertical gear-toothed cylinders hanging completely below the flat floor on narrow cylindrical necks (`side1.png` `y=655..745`), with washed-out pale undersides. In `sheet.jpg`, the repulsors are wide, low-profile bevelled saucers tucked into recessed wheel wells inside the fender blisters, canted slightly outward (`6\u00b0 to 10\u00b0` in front/rear orthos), with an intense cyan emissive pad. | Delete the exposed vertical stalks; recess the upper repulsor housings into contoured underbody wheel wells; widen and flatten the housings into smooth bevelled dark-metal saucers with 4 to 6 clean shroud segments instead of tall cog teeth; cant them outward by `6\u00b0 to 10\u00b0` and boost the cyan emissive glow. | In `side1.png`, repulsor pads sit directly inside recessed fender wells with zero exposed neck stalk and protrude at most `0.14 m` (`~16%` of body height) below the fender blister lip; front/rear views show slight outward cant and a bright cyan emitter ring (`#30D5FF` range). |\n| **F4** | **P1** (High) | [sheet.jpg](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/sheet.jpg): side glass `x=615..845, y=95..200` (`0.22..0.31, 0.06..0.13`), top glass/vent `x=445..695, y=985..1415` (`0.16..0.25, 0.64..0.92`), 3/4 view `x=1815..2205, y=645..790` (`0.66..0.80, 0.42..0.51`)<br>[side1.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/side1.png): `x=755..895, y=360..500` (`0.39..0.47, 0.33..0.46`)<br>[final1.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/final1.png): `x=735..1095, y=390..615` (`0.38..0.57, 0.36..0.57`) | **Flat upright windscreen and bulky grey base tube vs raked panoramic visor:** The rendered windscreen is a nearly flat rectangular sheet pitched steeply at `~53\u00b0` (`side1.png` `x=755..895`) with an exposed grey foam-like tube resting on the hood at its base (`final1.png` `x=735..1055, y=490..605`). In `sheet.jpg`, the windscreen is a deeply curved wrap-around visor raked at `~32\u00b0`, framed by polished chrome trim that flows continuously around the cockpit coaming, with a recessed dark cowl vent slot ahead of the glass base. | Curve the windscreen into a wrap-around horseshoe visor with tapered side glass; rake the A-pillars back to `30\u00b0 to 35\u00b0` from horizontal; replace the exposed grey base roll with a flush chrome cowl molding and a recessed dark cowl vent slot; connect the header/pillar chrome into a continuous cockpit surround trim. | In `side1.png`, windscreen rake is `30\u00b0 to 35\u00b0` from horizontal and spans `>= 0.65 m` front-to-back; in `final1.png`, the glass curves smoothly into side quarter glass with a flush chrome base, a recessed dark cowl vent forward of the glass, and no exposed grey tube. |\n| **F5** | **P2** (Medium) | [sheet.jpg](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/sheet.jpg): side wing `x=1440..1570, y=140..205` (`0.52..0.57, 0.09..0.13`), rear wing `x=835..1185, y=625..680` (`0.30..0.43, 0.41..0.44`)<br>[side1.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/side1.png): `x=1540..1640, y=390..475` (`0.80..0.85, 0.36..0.44`)<br>[rear1.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/rear1.png): wing `x=715..1060, y=345..480` (`0.56..0.83, 0.48..0.67`), poking pegs `x=770..790, y=420..432` & `x=965..985, y=360..372` | **Flat plank rear spoiler on tall vertical grey posts with penetrating top pegs:** The spoiler is a rigid, flat rectangular plank mounted high on vertical grey rectangular blocks whose top faces poke through the upper skin of the wing (`rear1.png` `x=770..790, y=420..432` and `x=965..985, y=360..372`). In `sheet.jpg`, it is a low-slung cambered wing with downward-curved tips following the rear fender line, carried on swept-back body-colored pylons. | Lower the wing height by ~35%; curve the airfoil planform and droop the outer wingtips toward the rear fenders; sweep and taper the two pylons rearward in body color (`sand gold`), terminating them cleanly inside the lower wing surface. | In `side1.png` and `rear1.png`, spoiler pylons are swept back, painted body color, and do not penetrate the top surface of the wing; outer wingtips curve downward to follow the rear haunch contour with `0.08 m to 0.12 m` deck clearance. |\n\n---\n\n0. **Blocked on you**: nothing.\n1. **What you changed**: Nothing was edited; I inspected the reference sheet and three renders to produce a five-point visual critique for the next modeling pass.\n2. **How you know it works**: I opened and visually compared [sheet.jpg](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/sheet.jpg), [final1.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/final1.png), [side1.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/side1.png), and [rear1.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4/rear1.png), and verified exact image pixel resolutions (`2752x1536`, `1920x1080`, `1920x1080`, `1280x720`) to anchor every finding's coordinates.\n3. **What would break if you were wrong**: If these five silhouette and construction gaps were ignored, the car would keep its slab-sided hull, missing top turbine barrels, blocky rear collar, dangling cog-like repulsors, and flat upright windscreen even after the author's six planned fixes land; undoing any over-correction only requires adjusting the mesh before the next render pass.\n4. **What you did NOT do**: I did not modify any scene or asset files, did not inspect `.blend` or `.glb` geometry directly, and did not repeat the six issues the author is already fixing.\n", "modelUsage": {"forge:build-gemini-4-high": {"inputTokens": 32200, "cacheReadInputTokens": 85139, "outputTokens": 15217, "listUSD": 0.234, "costBasis": "agy4-relay-log-list-price"}}, "session_id": "187ec734-2e8c-4e5e-993c-ca88c876212b", "worktree": "/tmp/landspeeder-critic/.forge-worktrees/1792182731-d26cb4", "branch": "task/1792182731-d26cb4", "items": {"num_turns": 5, "subtype": "SUCCESS", "served_models": ["gemini-4-argon"], "billing_source": "vertex forge-dev-492809 (Google grant)", "harness": "antigravity-cli"}}

The independent visual review also identified the windscreen rake and rear detailing as the biggest gaps from the sheet.

The current export passes the geometry and texture checks: about 67,000 triangles, eight materials, and a 5.3 MB GLB. The next clean build is waiting for the shared GPU. The exported model also loads correctly in a WebGL viewer, with the required sand-gold paint factor and neutral paint texture.

The asset is complete enough for the export checks. I’m checking the final surface shading, paint variants, and steering pivot before copying the deliverables into this directory.

In [rear4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/rear4.png), both vertical spoiler pylons drop straight into the open bay holes instead of landing on solid deck structure, and in [side4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/side4.png) the spoiler wing is a thick boxy slab rather than a swept airfoil ([sheet.jpg](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/sheet.jpg) top-left). | Add a recessed dark-metal inner bay tub/liner with a bevelled rim around each cutout, extend the buried turbine top casing forward inside the bay (staying below the deck line so it never mounts on top) so mechanical ribs fill the opening as in [sheet.jpg](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/sheet.jpg) (bottom-left), move the spoiler struts onto solid deck ribs inboard of the bays, and taper the wing profile. |\n| **2** | **Raised grey/white hood blocks and protruding cowl \"teeth\" break the sleek nose** | In [final4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/final4.png) and [side4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/side4.png), the two front hood details are raised dark-grey blocks with three bright white bars sticking up above the nose profile ([side4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/side4.png)), whereas [sheet.jpg](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/sheet.jpg) shows flush body-colored panel covers marked only by thin seam lines. At the windscreen base in [final4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/final4.png), the cowl vent is a row of ~20 tiny raised blocks sitting on top of the hood instead of a flush recessed dark slot. | Replace the raised grey/white hood boxes with flush sand-gold panel covers inset by a thin dark seam groove, and recess the cowl vent strip below the hood surface slightly ahead of the windscreen frame. |\n| **3** | **Rear exhausts lack emissive glow/depth and the rear center panel protrudes as a flat box** | In [rear4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/rear4.png), the twin nozzle rings look like flat, unlit pastel orange and pale blue paint around a flush black fan disc, missing the deep recess and bright emissive blue/orange core glow shown in [sheet.jpg](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/sheet.jpg) (rear view and material swatch). In [side4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/side4.png) and [rear4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/rear4.png), the black rear louver block sticks out behind the gold hull as a flat-sided box with jagged lower teeth hanging below the body sill. | Push the turbine fan cones deeper inside the nozzles so the inner barrel walls catch light, crank emission strength on the orange and cyan rings, and tuck the black center grille and lower diffuser forward into a recessed rear cavity flush with the lower hull line. |\n\n***\n\n0. **Blocked on you**: nothing.\n1. **What you changed**: Nothing; this was a read-only visual critique of [sheet.jpg](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/sheet.jpg), [final4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/final4.png), [side4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/side4.png), and [rear4.png](file:///tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/rear4.png) completed at 22:46 CET.\n2. **How you know it works**: Inspected all four image files directly in `/tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e/` and cross-checked every angle against the reference sheet and the excluded in-progress fixes.\n3. **What would break if you were wrong**: If the author skips fixing the open deck voids/spoiler strut collision, raised hood blocks, or unlit flat rear nozzles, the asset will still look unfinished in 3/4 and rear camera views even after the pad, flank-width, and paint-roughness fixes land.\n4. **What you did NOT do**: Did not inspect or edit the Blender generator script or any workspace files.\n", "modelUsage": {"forge:build-gemini-4-high": {"inputTokens": 23372, "cacheReadInputTokens": 33019, "outputTokens": 7632, "listUSD": 0.13, "costBasis": "agy4-relay-log-list-price"}}, "session_id": "2e6b9162-2dd0-4b25-9c4e-20ecd3dde2d9", "worktree": "/tmp/landspeeder-critic/.forge-worktrees/1792183467-06ab9e", "branch": "task/1792183467-06ab9e", "items": {"num_turns": 3, "subtype": "SUCCESS", "served_models": ["gemini-4-argon"], "billing_source": "vertex forge-dev-492809 (Google grant)", "harness": "antigravity-cli"}}

All delivery checks pass: 75,997 triangles, eight materials, a 5.47 MiB GLB, the required dimensions and 0.45 m hover clearance, and all 17 attachment sockets. The final GLB also passed the viewer’s recolouring and 30° steering tests. I’ve inspected the final, side, clay, and six-paint renders.
