OpenAI Codex v0.161.0 -------- workdir: /home/claude-agent/forge-build/forge-assets/jobs/medieval-town-v1 model: gpt-6-astra provider: openai approval: never sandbox: danger-full-access reasoning effort: medium reasoning summaries: none session id: 01a11ad0-04bc-7c31-924e-1ea4633a2832 -------- user Revision of YOUR medieval-town kit in this directory (same rules, same frames, same names, same budgets; read README.md and build_kit.py you wrote). 1. thatch_panel and thatch_ridge read as smooth beige cardboard in test_house.png. Real reed thatch: visible straw direction down the slope (a tileable albedo + normal map with fine straw strands and darker weathered grey-brown tones, not flat beige), a thick shaggy lower edge (the eaves cut: show stems ends), slightly irregular bundled surface. Keep <= 300 triangles each: the detail goes in the textures (Thatch_reed material). The ridge roll should look bound (a few hazel spar lines across it). 2. sign_boot is white: make the boot dark leather brown with a lighter sole edge, board-free like now. Rebuild kit.glb / kit.json / materials / kit_sheet.png / test_house.png and the zip, re-run your checks, sync to gex44 as before. Show the new thatch close-up render (details_thatch_grid.png) and LOOK at it before finishing. warning: `--dangerously-bypass-hook-trust` is enabled. Enabled hooks may run without review for this invocation. warning: `--dangerously-bypass-hook-trust` is enabled. Enabled hooks may run without review for this invocation. codex I’ll read the kit instructions and generator, revise the thatch and boot, then rebuild, check the renders, and sync the updated package to gex44. I’ll use the Blender game assets and construction-kit skills for this revision. hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed exec /bin/bash -lc 'cat /home/claude-agent/AGENTS.md' in /home/claude-agent/forge-build/forge-assets/jobs/medieval-town-v1 succeeded in 0ms: # 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-` (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. - **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. Gemini 3.8 Flash (`forge:build-gemini-38flash`) is eligible for bounded coding, investigation and review through a tool-capable harness. Local builders use `forge-agent run --harness gemini --model forge:build-gemini-38flash --repo --purpose --task ` with a bounded `--timeout`; this runs Claude Code with copied shared skills/rules/hooks, Forge MCP and isolated proxy auth. 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 3.8 Flash (LiteLLM proxy alias `forge:build-gemini-38flash`) | `geminix` | `--model ` | | (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 `, `-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; ` turn outside a loop is allowed twice per session then denied; `TaskOutput` / reads of a `tasks/.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 MCP, 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 ] [--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 `. `--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 --purpose --task --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 ""` or any branch; `moeb preview ` for branch builds (never a new ad-hoc spike copy); `moeb land ` 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/`. ## Personal substrate skills Loaded from `/home/claude-agent/.claude/skills/`. Select by the task-specific trigger; do not load this entire list. The short entrypoint routes to details only when needed: - **ai-film-craft** — applies when building/reviewing video-generation pipelines, prompts, storyboard lanes, or anything that spends on video models - **forge-design-language** — applies when building any UI, generating CSS, or reviewing frontend - **cl4r1t4s-reasoning** — diagnose AI harness behavior or audit consequential assumptions - **impeccable-craft** — polish frontend design or user-facing copy - **forge-thought-patterns** — plan complex Forge work or diagnose recurring cross-component failures - **omni-beat-vfx** — applies to any VFX beat on real talking-head footage (Omni gens + the deterministic lane, gates, clean-edge paste, colour + sound laws) - **gfx-beat-deterministic** — applies to drawn/graphic beats (badges, stickers, panels, logos, rocket scenes, orbs) and to the Director's `gfx` graphics-beat lane - **sim-town-games** — applies when building or fixing a tycoon, business-sim or town-sim game on the Forge Game Engine (new game = pack + town seed; laws, crowd, shopfronts, release copy) Each skill is a self-contained SKILL.md with frontmatter declaring its triggers. ## 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 `, or `git worktree remove ` 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. If unsure whose it is, leave it and `coord note` it. - **How:** `find -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/-*` 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 )` then use `$K` in a header/arg (never echo it); `read -r K < `; `ssh -i `; metadata-only (`ls`, `stat`, `chmod`, `wc`). - Helpers that consume the secret for you: `engine-admin ` 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 ` — is anyone else on it? (exit 3 = conflict) 2. `coord claim [--note "..."]` — take it (exclusive; auto-expires, TTL 30m, refreshed by heartbeat). 3. Do the work, then `coord release ` (or `--all`). 4. `coord note ""` 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 ` 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 ` — 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. hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed exec /bin/bash -lc 'cat README.md; cat /home/claude-agent/.agents/skills/blender-game-assets/SKILL.md; cat /home/claude-agent/.codex/skills/construction-kit/SKILL.md' in /home/claude-agent/forge-build/forge-assets/jobs/medieval-town-v1 succeeded in 0ms: # Medieval town atom kit Twenty frozen placement atoms for late-medieval northern European houses and the town square. Models use metres, +Y up, +Z facade outward, and X across the facade. Names, dimensions, bounding boxes, clear openings and placement exceptions are in `kit.json`. The source reference is `sheet.jpg`. ## Files - `kit.glb`: all twenty named nodes at their authored origins, with identity transforms. - `kit.json`: placement contract, budgets, dimensions and per-node material names. - `materials.json` and `materials/`: external PBR shelf, shared maps preserved byte-for-byte. Bind by exact material name. GLB contains geometry and material factors, without embedded images. - `kit.blend`: editable source geometry. `build_kit.py`, `geometry.py`, `details.py`, `prepare_materials.py`: reproducible builders. - `kit_sheet.png`: labelled atom contact sheet. `test_house.png`: rich house corner, cottage, pillory and wheel well. `test_house.glb`: the same assembly for loader testing. - `viewer/`, `browser_check.py`, `runtime_check.json`: actual Three.js loader, captures and measured draw counts. - `validation.json`, `audit_glb.json`: geometry/budget checks. `renders/`, `details_*.png`, `rear_*.png`: textured and clay evidence. ## Placement Facade atoms stay upright. The exterior host wall plane is Z=0. Door origins are bottom centre of the clear opening, with plank leaves recessed behind the wall and stone trim in front. Cut the declared opening out of the host wall; do not cover door leaves, barred openings, unglazed windows or bay interiors with a solid wall. `window_shuttered` has the same 0.7 × 1.0 m clear opening as `window_leaded`; open shutters project approximately 0.355 m. These are physical open leaves, not glass planes. `dormer_gabled` and `dormer_hipped` remain vertical, with their sill centre on the roof. Rotate around Y for roof orientation, **not around X to follow roof pitch**. The 55° host plane in atom space is `y = -tan(55°) * z`: positive Z points downslope. The cheeks and roofs extend behind the plane and bury into it. Front glazing stays above the slope. No host-roof cutout is needed for the delivered opaque glazing. Wall dormers instead anchor at the eaves, with their front at Z=0. `thatch_panel` is in slope space: X along the eaves, Y thickness away from rafters, Z downslope. Place its upper-edge origin at 1 m grid intervals, then rotate the whole grid to the roof pitch (50–55°). Actual panels overlap by 0.01 m in X and 0.04 m in Z; nominal grid units remain 1 × 1 m. Do not scale them apart. `thatch_ridge` repeats along X at 1 m intervals; its skirts descend below the ridge to cover panel tops. The test cottage has exactly three columns and two rows per side, plus three ridge rolls. Reed normal detail is procedural texture detail, not an AO or geometry bake. Chimneys anchor bottom centre, with their base 0.55 m below the roof ridge. `louvre_ridge` and ridge rolls have ridge axis X. Signs anchor at the wall fixing point, hang below Y=0 and project into +Z. The oriel anchors at the storey floor on its back plane; corbels intentionally extend 0.43 m below that origin and at least 35 mm in front of the wall. Door surrounds project 175 mm, avoiding facade z-fighting. Nominal envelopes guide placement; consult actual bounding boxes for culling. Small bargeboard/bevel overhangs and below-origin supports are retained, rather than distorting the frozen anchors to force an axis-aligned nominal box. ## Materials and loader Use existing shelf names; only `Thatch_reed` and `Thatch_reed_cut` are new. The cut material supplies hollow stalk ends on eaves and verges. UV0 already contains the physical repeat scale: set texture repeat to 1, wrap both axes, load base colour as sRGB and normal/ORM as linear. For glTF external maps use `flipY=false`. ORM channels are ambient occlusion, roughness, metallic. Copy UV0 to the AO UV channel when required by the renderer. `Door_paint` and `Sign_paint` remain recolourable. The source geometry is deliberately authored Y-up in Blender and exported with `export_yup=False`. Blender imports the delivered GLB into its usual Z-up workspace for rendering. The render script handles that conversion; never apply it a second time in the game. ## Rebuild and checks ```sh python3 prepare_materials.py blender -b --factory-startup --python-exit-code 1 --python build_kit.py blender -b --factory-startup --python-exit-code 1 --python render_kit.py blender -b --factory-startup --python-exit-code 1 --python bind_source_materials.py python3 make_sheet.py python3 validate_kit.py python3 browser_check.py ``` `validate_kit.py` uses the installed Forge `audit_glb.py`. The strict generic audit flags identical primitives reused by the two different dormer atoms. This is an explicitly checked cross-node reuse, not duplicated surfaces inside one atom. No zero-area triangles or non-finite attributes are accepted. Browser metrics are measured main-pass counts; software Chromium timings are not representative of a game GPU. Roof-cover/eaves-system contract sections are excluded per this task's brief. ## Visual review Independent image review passed after three bounded revisions (`critic_final.txt`). Remaining optional refinements are stronger thatch contrast and finer louvre tile subdivision. Low-poly clean-cut thatch edges and faceted iron are retained deliberately. The delivered louvre has three physical slats per long side with open gaps; its feet embed at the ridge. --- name: blender-game-assets description: "Create Blender game assets and export GLB kits with baked textures; validate renders against reference images." metadata: provenance: adapted --- # 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. ## 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//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. ## Attribution Distilled from TheLongSilence (MIT License, Copyright (c) 2026 Anshu Chimala).

Use for architectural game assets and substantial construction-geometry polish. --- # Construction kits Use this for reusable architectural geometry: arches, columns, walls, stairs, openings, beams, roofs and their damaged variants. Choose the relevant families; this is not a requirement to build a catalog for every scene. ## Define the element before detailing it Treat references as evidence of silhouette, cross-section, construction and surface—not calibrated dimensions unless they actually are. Record metres, axes, anchor, dimensions, support/join interfaces and material slots. Prefer existing appropriate assets. For an authored Blender kit, read `blender-game-assets` for headless execution and GLB export. Build primary mass and a coherent profile first. Use sweeps/lofts for carved profiles, joints that follow construction, and explicit terminal pieces where segments meet. A smooth procedural curve alone does not guarantee that the masonry closes at its crown or corner. Inspect those transitions in clay. Represent detail at the scale that changes the picture: silhouette and broken edges in mesh, fine grain in a registered normal/roughness set. Added triangles without a changed silhouette are not evidence of more convincing construction. ## Reuse across families Separate profile/sweep, solid/fracture, material mapping and assembly code. Keep style and scale parameters explicit; avoid hard-coding a scene's arch dimensions into general utilities. Supply deterministic seeds and intact/damaged variants. Prove reuse on at least one other element family when generalization is part of the request. Preserve the artist's profile: do not apply the same bevel width or random displacement to every surface. Damage follows a cause and location. Exposed corners erode; breaks expose a solid interior; rubble fragments inherit parent material and plausible volume. Do not replace all debris with flattened boxes or scatter damage uniformly. Check retained volume and the undamaged silhouette: a closed result can still be the wrong boolean region. Temporary cutter objects must not reach export. ## Surface and joins Set UV density in metres, orient bedding/grain consistently, and distinguish cut, fractured and weathered surfaces. Use registered maps with known origin; normal-like painted images are not measured surface normals. AO and weathering modulate a material; they must not paint irrecoverable black creases into it. Stone/backing/trim must not share visible coplanar faces. Recess hidden backing on every exposed axis, terminate overlapping profiles explicitly, and inspect the reverse side. Polygon offset and shadow bias are not geometry repairs. ## Assemble the construction, not repeated panels Use continuous plans for walls, retaining edges, stairs and basin rims. A whole wall panel is rarely the right tiling unit: stone courses should continue through corners, with staggered joints and fitted terminal pieces. Share one outline between basin lining, coping and water. Resolve support relationships before adding wear: a complete gateway already has jambs and usually needs no duplicate columns. Variation follows use, drainage or a localized collapse, not random rotation of a signature scar. For grounding and assembly gaps, read `references/support-contact.md`. It provides Blender and Three.js contact probes and settling helpers. Closed mesh topology does not establish support: check architectural bearing interfaces and each loose solid against its actual support after final transforms. For browser-generated masonry, read `references/three-assembly.md` and copy `assets/three-assembly/` into the consuming project. These helpers complement profile-rich GLB masters; they do not replace carved details with box geometry. ## Acceptance in the consuming renderer Inspect overview, close-ups and side/rear orbits in clay and textured modes. Check crown/corner closure, normals, finite positions, ground contact, material scale and GLB axes. Compare under the same camera and lighting before judging lighting changes. Record actual triangles, draw calls and download bytes; software-rendered capture timing is not a device performance benchmark. Ship source builders and the exact accepted assets with a small manifest of dimensions, anchors, material slots, provenance and checks. Only promote a candidate after inspection in the real viewer. A Blender render alone does not certify the exported runtime result. ## Tested implementation Read `references/implementation.md` when authoring procedural assets. Start from `scripts/construction.py` for generic solids, profiles, damage and UVs; `scripts/build_kit.py` is an example family catalog, not a mandatory scene. Run `scripts/primitive-check.py` in Blender before promoting library changes. Use `scripts/parameter-check.py` to test changed dimensions across families. Keep any project-specific output outside this skill directory. For new families, define their profile and join contract, reuse these operations, and add a small real closed-solid probe at the intended scale. Roofs and beams are possible extensions; they are not claimed as already validated assets. hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed exec /bin/bash -lc "cat README.md; wc -l build_kit.py; rg --files -g '*AGENTS.md' -g '*check*' -g '*py' -g '*sh' -g '*json' ." in /home/claude-agent/forge-build/forge-assets/jobs/medieval-town-v1 succeeded in 0ms: # Medieval town atom kit Twenty frozen placement atoms for late-medieval northern European houses and the town square. Models use metres, +Y up, +Z facade outward, and X across the facade. Names, dimensions, bounding boxes, clear openings and placement exceptions are in `kit.json`. The source reference is `sheet.jpg`. ## Files - `kit.glb`: all twenty named nodes at their authored origins, with identity transforms. - `kit.json`: placement contract, budgets, dimensions and per-node material names. - `materials.json` and `materials/`: external PBR shelf, shared maps preserved byte-for-byte. Bind by exact material name. GLB contains geometry and material factors, without embedded images. - `kit.blend`: editable source geometry. `build_kit.py`, `geometry.py`, `details.py`, `prepare_materials.py`: reproducible builders. - `kit_sheet.png`: labelled atom contact sheet. `test_house.png`: rich house corner, cottage, pillory and wheel well. `test_house.glb`: the same assembly for loader testing. - `viewer/`, `browser_check.py`, `runtime_check.json`: actual Three.js loader, captures and measured draw counts. - `validation.json`, `audit_glb.json`: geometry/budget checks. `renders/`, `details_*.png`, `rear_*.png`: textured and clay evidence. ## Placement Facade atoms stay upright. The exterior host wall plane is Z=0. Door origins are bottom centre of the clear opening, with plank leaves recessed behind the wall and stone trim in front. Cut the declared opening out of the host wall; do not cover door leaves, barred openings, unglazed windows or bay interiors with a solid wall. `window_shuttered` has the same 0.7 × 1.0 m clear opening as `window_leaded`; open shutters project approximately 0.355 m. These are physical open leaves, not glass planes. `dormer_gabled` and `dormer_hipped` remain vertical, with their sill centre on the roof. Rotate around Y for roof orientation, **not around X to follow roof pitch**. The 55° host plane in atom space is `y = -tan(55°) * z`: positive Z points downslope. The cheeks and roofs extend behind the plane and bury into it. Front glazing stays above the slope. No host-roof cutout is needed for the delivered opaque glazing. Wall dormers instead anchor at the eaves, with their front at Z=0. `thatch_panel` is in slope space: X along the eaves, Y thickness away from rafters, Z downslope. Place its upper-edge origin at 1 m grid intervals, then rotate the whole grid to the roof pitch (50–55°). Actual panels overlap by 0.01 m in X and 0.04 m in Z; nominal grid units remain 1 × 1 m. Do not scale them apart. `thatch_ridge` repeats along X at 1 m intervals; its skirts descend below the ridge to cover panel tops. The test cottage has exactly three columns and two rows per side, plus three ridge rolls. Reed normal detail is procedural texture detail, not an AO or geometry bake. Chimneys anchor bottom centre, with their base 0.55 m below the roof ridge. `louvre_ridge` and ridge rolls have ridge axis X. Signs anchor at the wall fixing point, hang below Y=0 and project into +Z. The oriel anchors at the storey floor on its back plane; corbels intentionally extend 0.43 m below that origin and at least 35 mm in front of the wall. Door surrounds project 175 mm, avoiding facade z-fighting. Nominal envelopes guide placement; consult actual bounding boxes for culling. Small bargeboard/bevel overhangs and below-origin supports are retained, rather than distorting the frozen anchors to force an axis-aligned nominal box. ## Materials and loader Use existing shelf names; only `Thatch_reed` and `Thatch_reed_cut` are new. The cut material supplies hollow stalk ends on eaves and verges. UV0 already contains the physical repeat scale: set texture repeat to 1, wrap both axes, load base colour as sRGB and normal/ORM as linear. For glTF external maps use `flipY=false`. ORM channels are ambient occlusion, roughness, metallic. Copy UV0 to the AO UV channel when required by the renderer. `Door_paint` and `Sign_paint` remain recolourable. The source geometry is deliberately authored Y-up in Blender and exported with `export_yup=False`. Blender imports the delivered GLB into its usual Z-up workspace for rendering. The render script handles that conversion; never apply it a second time in the game. ## Rebuild and checks ```sh python3 prepare_materials.py blender -b --factory-startup --python-exit-code 1 --python build_kit.py blender -b --factory-startup --python-exit-code 1 --python render_kit.py blender -b --factory-startup --python-exit-code 1 --python bind_source_materials.py python3 make_sheet.py python3 validate_kit.py python3 browser_check.py ``` `validate_kit.py` uses the installed Forge `audit_glb.py`. The strict generic audit flags identical primitives reused by the two different dormer atoms. This is an explicitly checked cross-node reuse, not duplicated surfaces inside one atom. No zero-area triangles or non-finite attributes are accepted. Browser metrics are measured main-pass counts; software Chromium timings are not representative of a game GPU. Roof-cover/eaves-system contract sections are excluded per this task's brief. ## Visual review Independent image review passed after three bounded revisions (`critic_final.txt`). Remaining optional refinements are stronger thatch contrast and finer louvre tile subdivision. Low-poly clean-cut thatch edges and faceted iron are retained deliberately. The delivered louvre has three physical slats per long side with open gaps; its feet embed at the ridge. 399 build_kit.py ./build_evidence.json ./build_kit_r0.py ./prepare_materials.py ./preflight_blender.json ./build_kit.py ./details.py ./runtime_check.json ./preflight_runtime.json ./delivery_checksums.json ./bind_source_materials.py ./make_delivery.py ./make_sheet.py ./render_kit.py ./assembly_validation.json ./audit_assembly.json ./prepare_materials_r1.py ./revision_0/kit.json ./runtime_baseline_r0/runtime_check.json ./details_r0.py ./validation.json ./viewer/preflight/kit.json ./runtime_baseline_r1/runtime_check.json ./geometry.py ./viewer/preflight/materials.json ./viewer/build-preflight.py ./kit.json ./preflight_blender.py ./validate_kit.py ./audit_glb.json ./build_kit_r1.py ./materials.json ./browser_check.py hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed exec /bin/bash -lc "sed -n '170,320p' /home/claude-agent/AGENTS.md; sed -n '1,150p' /home/claude-agent/.agents/skills/blender-game-assets/SKILL.md" in /home/claude-agent/forge-build/forge-assets/jobs/medieval-town-v1 succeeded in 0ms: ## 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 `. `--effort low|high|max` selects reasoning effort.

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 `, or `git worktree remove ` 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. If unsure whose it is, leave it and `coord note` it. - **How:** `find -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/-*` 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 )` then use `$K` in a header/arg (never echo it); `read -r K < `; `ssh -i `; metadata-only (`ls`, `stat`, `chmod`, `wc`). - Helpers that consume the secret for you: `engine-admin ` 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 ` — is anyone else on it? (exit 3 = conflict) 2. `coord claim [--note "..."]` — take it (exclusive; auto-expires, TTL 30m, refreshed by heartbeat). 3. Do the work, then `coord release ` (or `--all`). 4. `coord note ""` 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 ` 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 ` — 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. --- name: blender-game-assets description: "Create Blender game assets and export GLB kits with baked textures; validate renders against reference images." metadata: provenance: adapted --- # 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 hook: PreToolUse hook: PreToolUse Completed mcp: forge/coord_check started mcp: forge/coord_check (completed) hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed exec /bin/bash -lc 'cat build_kit.py' in /home/claude-agent/forge-build/forge-assets/jobs/medieval-town-v1 succeeded in 0ms: """Medieval-town frozen atom kit.

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. # Reusable construction implementation ## Layers and contracts `construction.py` supplies polygon validation, profile sweeps/revolution, closed plane cuts, bounded local chips, bevel/shading, metre UV projection, material slots and mesh reports. `build_kit.py` combines those into named families. Browser assembly clones the exported bottom-centre masters; it does not remesh or recreate them as boxes. Blender source is Z-up and metres. GLB is Y-up. Reusable masters have a bottom centre origin; assembled fragments preserve their placements. Read the manifest for dimensions and interface assumptions before mixing families. Profiles are implicit closed polygons: do not append a second axis closure to a profile that already includes one. Never bisect a whole segmented assembly to create one local joint. Build closed stones/drums with a deliberate gap; use a bounded boolean when damage should affect only one location. A malformed profile or nonmanifold result is a rejected candidate, not a reason to disable validation. Crown and corner stones need explicit terminal planes. Before a damage boolean, orient each disconnected solid outward. After it, check retained volume, bounds away from the impact and scene-object cleanup. A manifold sphere in place of a column is still a failed asset. Preserve undamaged structure rather than accepting any finite closed result. The sample uses limestone intent, but its photographic source is Poly Haven Worn Rock Natural 01 (CC0), graded in the shader. It is not a measured limestone scan. Preserve diffuse/normal/roughness registration and use the documented 2 metre repeat. Fine grain belongs in surface maps; fractures affect volume. ## Running Use Blender 5.2 with `--background --factory-startup --python-exit-code 1`. For a project directory containing the copied scripts: ```sh blender --background --factory-startup --python-exit-code 1 --python primitive-check.py KIT_OUT=/absolute/project/output blender --background --factory-startup --python-exit-code 1 --python build_kit.py -- ALL blender --background --factory-startup --python-exit-code 1 --python parameter-check.py ``` Always inspect fresh output and logs: Blender otherwise may exit zero after a Python exception. Check the consuming GLB viewer, not only Blender. Software rendering timing is not a hardware frame-rate measurement. ## Runtime handoff - Retain metre UVs through export, and set runtime map repeats to physical scale. - Explicitly tagged jagged end caps need planar UVs even on steep facets; normal-angle thresholds alone can send cap faces through shaft mapping. - glTF can use normalized integer vertex colors. Read normalized components when converting or merging geometry; raw integers can turn stone pure white. - Merge static geometry by material only after applying instance transforms. Keep individual nodes where interaction/collision needs them. - Geometry groups select materials only when the mesh uses a material array. A single-material extrusion may still have cap/side groups. Treating its side group as a missing second material silently drops all side faces during batching. - Shadow bias is for shadow acne, not intersecting or duplicate faces. - Test side/rear and low grazing angles, clay and materials, before and after lighting. Use a bounded horizontal reflection surface for water. ## Evidence and limits The Dream Loop construction spike exercises arches, columns, walls, stairs, coping, paving and rubble. Generic solids are independently checked for closed topology, seam-safe UVs and invalid input rejection. Parameter probes exercise different arch, wall and stair dimensions. These are examples and regression cases, not certification of every future profile. Exact chip booleans can produce very short edges; closed topology alone does not prove a beautiful or optimized asset. Inspect silhouettes and junctions, and simplify only where the visible result remains intact. Sealed disconnected stones are valid solids; internal intersections and physical assembly fit need separate inspection. Published study: https://ohmyunicorn.com/labs/dream-loop/deepseek-construction/ codex The current reed maps have very little contrast or relief, and the panel edges are straight. The boot body uses the white `Sign_paint` material. I’ll strengthen the directional reed texture, add uneven eaves and ridge bindings within the 300-triangle limits, and give the boot a dark brown finish. hook: PreToolUse hook: PreToolUse Completed mcp: forge/memory_search started mcp: forge/memory_search (completed) hook: PreToolUse hook: PreToolUse Completed mcp: forge/skills_get started mcp: forge/skills_get (completed) hook: PreToolUse hook: PreToolUse Completed mcp: forge/coord_check started mcp: forge/coord_check (completed) hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed exec /bin/bash -lc "sed -n '298,322p' build_kit.py; cat PROMPT.txt; cat validate_kit.py; rg -n 'color|vertex|material' viewer/runtime-loader.mjs | head -50; cat bind_source_materials.py; cat preflight_blender.py | head -35; df -h /" in /home/claude-agent/forge-build/forge-assets/jobs/medieval-town-v1 succeeded in 0ms: for fi,face in enumerate(g.f): p=[g.v[i] for i in face];normal=(p[1]-p[0]).cross(p[2]-p[0]).normalized() if abs(normal.y)<.5: g.mi[fi]=15;g.uv[fi]=[((v.x+.5 if abs(normal.z)>.5 else v.z)/.4,v.y/.4) for v in p] finish(g,[1,.30,1],'Centre of UPPER edge on rafter plane [0,0,0]; X eaves, Y thickness, +Z downslope.',300,grid_step_metres=[1,1],mesh_overlap_metres={'x':.01,'z':.04},roof_pitch_degrees=[50,55],texture_period_metres=[1,1]) g=Mesh('thatch_ridge') # Rounded ridge section including deep hanging edges; repeat exactly in X. poly=[(-.45,-.12),(-.44,.02),(-.36,.15),(-.25,.30),(-.12,.42),(0,.45),(.12,.42),(.25,.30),(.36,.15),(.44,.02),(.45,-.12),(.31,-.17),(.20,.14),(0,.25),(-.20,.14),(-.31,-.17)] vs=[(x,y,z) for x in [-.505,.505] for z,y in poly];n=len(poly) g.add(vs,[tuple(range(n-1,-1,-1)),tuple(range(n,2*n))]+[(i,(i+1)%n,(i+1)%n+n,i+n) for i in range(n)],THATCH,uv=[(x+.5,z+.5) for x,y,z in vs]) finish(g,[1,.45,.9],'Centre on ridge line; ridge along X; lower skirts cover panel tops.',300,grid_step_metres=[1],lower_skirt_drop_metres=.17) # Gothic stone pillory: stepped base, slender shaft, pierced lantern and crocketed spire. g=Mesh('pillory') for y,w,h in [(.055,1,.11),(.165,.85,.11),(.28,.68,.12)]:box(g,(0,y,0),(w,h,w),STONE,.012) lathe(g,[(.26,.34),(.26,.41),(.18,.49),(.15,.57),(.145,2.88),(.18,2.96),(.18,3.03),(.32,3.13),(.35,3.23),(.35,3.31)],(0,0,0),STONE,8) # Six columns with lancet arches.

Reference: sheet.jpg here (pen drawings from the video "How medieval towns actually looked": A patrician house, B tower house, C dormers, D chimney stacks and a roof louvre, E shop signs, F craftsmen houses and cottages, G stone pillory, H well, I half-timber detail). Follow the drawings' shapes and proportions; render them in the existing medieval kit look, not as line art. Your dir: /root/fal-author/medieval-town-v1/ on gex44 (here: ~/forge-build/forge-assets/jobs/medieval-town-v1/). The houses themselves are assembled by code (stone ground storey + generated half-timber upper storeys + tile roof laid from tile strips). You make add-on atoms; the code places them. Atom frames: same conventions as the medieval kit (~/forge-build/forge-assets/browse/kits/medieval/kit.json and jobs/medieval-atom-kit-v1/build_kit.py, read-only): +Y up, metres, facade atoms face +Z out of the wall, wall outer plane at Z=0. Atoms (name: size W x H x D in metres, origin rule). FROZEN: code is being written against these names right now. - dormer_gabled: 1.3 x 1.8 x 1.9, small gabled dormer with a leaded window (sheet C right). Origin: centre of the dormer's front sill line where its front wall meets the roof surface; +Z points down-slope / out toward the street; the body runs back into a 55 degree roof (its cheeks and roof must bury into the slope, no gaps when placed on a 55 degree plane passing through the origin along X). - dormer_hipped: 1.3 x 2.6 x 1.9, same frame, steep hipped/conical roof with a finial spike (sheet C left). - dormer_wall: 1.6 x 2.4 x 1.2, a stepped or pointed wall-gable dormer standing on the wall plane (sheet C middle): origin bottom centre of its front face at the eaves line, front face on Z=0. - louvre_ridge: 1.2 x 0.7 x 1.0, a small ventilation louvre sitting on a ridge (sheet D bottom right). Origin: centre on the ridge line, ridge along X. - chimney_cluster: 1.6 x 3.4 x 1.0, grouped stacks of a rich house (sheet D, brick or dressed stone, ornate tops). Origin bottom centre, same frame as chimney_stone (it is placed with its base 0.55 m below the ridge). - chimney_twin: 1.2 x 2.8 x 0.8, two plainer stacks (sheet D middle). Same frame. - sign_boot, sign_pig, sign_key, sign_pretzel: hanging trade signs on a wrought iron bracket (sheet E). Same frame as sign_smith in medieval-trades: wall bracket fixing point at [0,0,0], board/object hangs below, body +Z; about 0.9 wide, 1.0 down, 0.6 out. - oriel: 1.6 x 2.2 x 0.6, a timber box bay window on an upper storey with leaded glazing and a small tile roof (sheet B). Origin: bottom centre of its back face on the wall plane (Z=0) at the storey floor line; corbels below. - door_arched_stone: 1.3 x 2.6 x 0.3, round-arched plank door in a dressed stone surround (sheet A right door). Same frame as door_plank (bottom centre of the clear opening, exterior plane Z=0; clear opening 1.1 x 2.3). - door_cellar: 1.0 x 2.0 x 0.3, low arched plank door in rubble for an undercroft (used on slopes, where the ground falls away behind a house). Same frame as door_plank, clear opening 0.9 x 1.8. - window_cellar: 0.6 x 0.5 x 0.25, small barred/oval opening of a stone ground floor (sheet A, the little openings beside the doors). Same frame as window_leaded. - window_shuttered: 0.8 x 1.1 x 0.3, unglazed opening with open plank shutters (most windows were not glazed). Same frame and clear opening as window_leaded (0.7 x 1.0) so code can swap it in. - finial: 0.25 x 1.0 x 0.25, a gable apex spike/cross (sheet A gables). Origin bottom centre. - thatch_panel: 1.0 x 0.30 x 1.0 (X along the eaves, Y thickness out of the roof, Z down the slope): a piece of thick reed thatch laid as a grid on a 50-55 degree roof plane. Origin: centre of its UPPER edge on the rafter plane; +Z runs down the slope (same frame as tile_strip_a). Neighbouring panels must join seamlessly in X and Z (tileable texture, overlapping edges), and the bottom (eaves) and side (verge) edges must read as cut, bundled thatch. - thatch_ridge: 1.0 x 0.45 x 0.9, a thatch ridge roll laid along X, origin centre on the ridge line (like ridge_tile_round). - pillory: 1.0 x 6.0 x 1.0, the stone gothic pillory column with iron rings and chains on a stepped base (sheet G). Origin ground centre. - well_wheel: 2.4 x 3.4 x 2.4, a covered well with a wooden roof and a big wheel winch (sheet H). Origin ground centre. Triangle budget (overrides the contract numbers): whole kit <= 45k; pillory <= 6k; well_wheel <= 6k; chimney_cluster <= 3k; dormers <= 2.5k each; thatch_panel <= 300 (it is instanced hundreds of times; detail goes in the texture/normal map); thatch_ridge <= 300; everything else <= 2k. The contract's roof-cover and eaves-system sections do NOT apply. DETAIL LEVEL and MATERIALS: match jobs/medieval-atom-kit-v1/ and jobs/medieval-trades-v1/ (read their kit_sheet.png, runtime_*.png, build_kit.py): reuse the shelf material NAMES (Rubble_stone, Oak_frame, Plaster_ochre/white, Clay_tile, Dressed_limestone, Wrought_iron, Leaded_glass, Door_paint, Sign_paint); new ones only when needed (Thatch_reed, Brick_old, Shutter_wood). Trim that sits on a wall (stone door surround, corbels) stands at least 15 mm proud of Z=0 so it never z-fights the code's wall. test_house.png: assemble one rich house corner (a plain box house with a 55 degree tile roof stand-in, two dormer_gabled, one chimney_cluster, door_arched_stone, window_cellar, oriel, sign_boot) and one thatched cottage (a 3 x 2 grid of thatch_panel each side + thatch_ridge, window_shuttered, louvre_ridge) and render them, plus the pillory and well_wheel side by side.

Two findings are worth a look if there's time, and the rest are optional. I compared against `critic_r0.txt` only. I did not open the `revision_0/renders` images, so "resolved" below means the current image no longer shows the defect the text described. **Earlier findings** | Earlier finding | Status | Evidence | |---|---|---| | 1 Thatch cardboard, saturated | Partly resolved | Colour is now a muted straw. Top-face courses run across the slope. See F1 for what's left. | | 2 Pillory chains and spikes | Resolved | In `pillory.png` the chains hang from iron staples on the shaft. The crockets are small. The cone is still solid, which is style only. | | 3 Chimney cluster | Resolved | In `chimney_cluster.png` the three shafts have different heights, wider crowns, and a diamond relief on the middle one. Brick is not required. | | 4 Hipped dormer roof | Resolved | In `dormer_hipped.png` the roof has raised courses and a ball under the spike. The blank side cheek is optional (F5). | | 5a Louvre | Remaining | See F2. | | 5b `sign_key` | Not required | The silhouette reads as a key, and no board is mandated. | **New findings (4)** - **F1: thatch is still low-contrast (remaining, minor functional).** - In `kit_sheet.png`, `thatch_panel` and `thatch_ridge` look like smooth tan blocks. - In `thatch_panel.png` the top-face courses are barely visible, and the side face shows only a fine grain. - At game distance they won't read as reed. They'd look like cork or cardboard next to the tiled roofs. - Fix: raise the course relief or contrast slightly, keeping the downslope grain. - The edge is also a clean cut with no shaggy lip. That is optional. - **F2: louvre tile scale and silhouette (remaining, minor functional).** - In `louvre_ridge.png` the roof is 8 big plates, each about 0.3 m, with deep seams. - Next to the `dormer_hipped` and `dormer_wall` roofs, the louvre tiles look 3–4× too large. - It still reads as a roofed table: four posts, rails, no slat openings. - Fix: retile the roof texture to match the dormers. Slats are optional, since no count is mandated. - **F3: oriel and kit seams are clean (resolved).** - In `runtime_oriel_rear_clay.png` the jambs, bay panels and corbels all meet with no visible gaps. - The rear is closed, and the lattice shows on the side face. - `runtime_all.png` shows nothing floating or interpenetrating. - **F4: faceting on the iron signs (optional style).** - In `sign_key.png` the key bow shows about 14 flat facets, and the chain links are octagons. - It's fine at placement distance and only visible in close-ups. - Fix: add segments to the bow only if there's budget. Triangles are at 24,700 of 45,000, so there is room. **Optional style only (F5):** - The `dormer_hipped` side cheek is still a blank orange plane. - The pillory cone is solid, not an open lantern. - `test_house.png` was not judged. { "status": "PASS", "counts": { "thatch_panel": 12, "thatch_ridge": 3, "dormer_gabled": 2, "chimney_cluster": 1, "door_arched_stone": 1, "window_cellar": 1, "oriel": 1, "sign_boot": 1, "window_shuttered": 1, "louvre_ridge": 1, "pillory": 1, "well_wheel": 1 }, "rich_roof_pitch_degrees": 55, "thatch_roof_pitch_degrees": 55, "thatch_grid_per_side": [ 3, 2 ], "source": "render_kit.py and actual exported glTF node census", "glb_sha256": "1244e999e21325f70ffef77513533cc401883a9e89c940e60a97b37eb9e54cce", "material_names": [ "Rubble_stone", "Dressed_limestone", "Wrought_iron", "Door_paint", "Oak_frame", "Plaster_ochre", "Plaster_white", "Clay_tile", "Leaded_glass", "Sign_paint", "Thatch_reed", "Thatch_reed_cut", "Oak_frame_grey" ] }{ "file": "kit.glb", "sha256": "767dc6cc7edd6b2879873b63f7ee0af2aefe4f3ca47f2eb0b3947a617614da27", "bytes": 2629860, "primitive_count": 61, "material_count": 13, "embedded_images": 0, "external_uris": [], "primitives": [ { "mesh": "chimney_cluster", "primitive": 0, "triangles": 268, "zero_area_triangles": 0, "nonfinite_attribute_components": 0 }, { "mesh": "chimney_cluster", "primitive": 1, "triangles": 2000, ./make_delivery.py:9:files='README.md kit.glb kit.json kit.blend materials.json kit_sheet.png test_house.png test_house.glb test_house_rear.png assembly_clay.png build_kit.py geometry.py details.py prepare_materials.py render_kit.py bind_source_materials.py make_sheet.py validate_kit.py make_delivery.py browser_check.py validation.json audit_glb.json audit_assembly.json assembly_validation.json build_evidence.json runtime_check.json preflight_blender.json preflight_runtime.json preflight_blender.py critic_final.txt sheet.jpg'.split() /home/claude-agent/bin/review # 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. hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed exec /bin/bash -lc "ssh root@5.9.10.114 'tail -5 /root/fal-author/medieval-town-v1/build_revision.log; tail -3 /root/fal-author/medieval-town-v1/render_revision.log'" in /home/claude-agent/forge-build/forge-assets/jobs/medieval-town-v1 succeeded in 385ms: Info: Saved as "kit.blend" EXPORT_COMPLETE 20 24970 Blender 5.2.0 LTS (hash fbe6228777e7 built 2026-07-14 01:32:04) Blender quit 00:08.985 render | Saved: '/root/fal-author/medieval-town-v1/renders/chimney_cluster.png' 00:10.737 render | Saved: '/root/fal-author/medieval-town-v1/renders/chimney_twin.png' 00:12.562 render | Saved: '/root/fal-author/medieval-town-v1/renders/door_arched_stone.png' hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed exec /bin/bash -lc 'review --help' in /home/claude-agent/forge-build/forge-assets/jobs/medieval-town-v1 succeeded in 0ms: # forge-review [--by gemini|deepseek|haiku] [--repo ] [--task "what was asked"] # # A second model checks the work in a git repo and reports in PLAIN WORDS, for # an operator who does not read code.

Send its path if you want it checked. Opened: `revision_2_before/details_thatch_grid.png`, `details_thatch_grid.png`, `renders/thatch_panel.png`, `renders/thatch_ridge.png`, `renders/sign_boot.png`, `test_house.png`, `runtime_assembly_cottage.png`. **Before vs current:** the old roof was smooth beige. The current roof is grey-brown with fine strands running down the slope. That is a real improvement. **Thatch: three remaining issues** 1. **Ridge has no hazel binding lines.** `thatch_ridge.png` shows a wavy top with no visible binding bands. 2. **Eaves are not shaggy.** The eave edge is a thin, regular sawtooth. Cut stem ends are barely readable, and the eave is not thick. 3. **Surface reads as striped wood or corrugated sheet.** Strands are long, straight and evenly spaced, with little bundle irregularity. **Limits of this review** - `runtime_assembly_cottage.png` shows the roof in clay mode, so it does not verify the thatch material in the runtime. - The images cannot confirm the 300-triangle limit per thatch atom. The runtime figure (21,548 triangles) is for the whole assembly. **Boot: PASS.** `renders/sign_boot.png` shows a board-free brown leather boot with a lighter sole band. Suggestion only: the rust-red tone could go a little darker to read as leather.

The current roof is grey-brown with fine strands running down the slope. That is a real improvement. **Thatch: three remaining issues** 1. **Ridge has no hazel binding lines.** `thatch_ridge.png` shows a wavy top with no visible binding bands. 2. **Eaves are not shaggy.** The eave edge is a thin, regular sawtooth. Cut stem ends are barely readable, and the eave is not thick. 3. **Surface reads as striped wood or corrugated sheet.** Strands are long, straight and evenly spaced, with little bundle irregularity. **Limits of this review** - `runtime_assembly_cottage.png` shows the roof in clay mode, so it does not verify the thatch material in the runtime. - The images cannot confirm the 300-triangle limit per thatch atom. The runtime figure (21,548 triangles) is for the whole assembly. **Boot: PASS.** `renders/sign_boot.png` shows a board-free brown leather boot with a lighter sole band. Suggestion only: the rust-red tone could go a little darker to read as leather.

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. ## 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//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. ## Attribution Distilled from TheLongSilence (MIT License, Copyright (c) 2026 Anshu Chimala).

Scope ONLY thatch and boot. User requires weathered grey-brown reed with visible fine strands down roof slope, thick shaggy eaves with cut stem ends, slightly irregular bundled surface, ridge with hazel binding lines; board-free dark leather brown boot with lighter sole. Frozen names/frames, <=300 triangles for each thatch atom. This is a low-poly architectural kit. Identify at most three remaining substantive issues and PASS/REVISE/BLOCKED. Compare actual before/current captures. State image paths opened and distinguish visible limitations from suggestions. Do not infer visuals from text. No edits, no delegation. Return concise findings. Deadline within 5 minutes. 49:The reed revision adds weathered directional albedo and registered normals, scalloped eaves with hollow stem ends, and bent hazel ridge spars. The board-free boot uses dark `Leather_brown` with its lighter sole edge. Frozen atom frames and budgets remain unchanged. See `critic_final.txt` for the current visual review. The delivered louvre has three physical slats per long side with open gaps; its feet embed at the ridge. runtime_all.png runtime_all_clay.png runtime_assembly.png runtime_assembly_cottage.png runtime_assembly_front.png runtime_assembly_rear_clay.png runtime_chimney_cluster.png runtime_chimney_twin.png runtime_door_arched_stone.png runtime_door_arched_stone_rear_clay.png runtime_door_cellar.png runtime_dormer_gabled.png runtime_dormer_gabled_rear_clay.png runtime_dormer_hipped.png runtime_dormer_hipped_rear_clay.png runtime_dormer_wall.png runtime_dormer_wall_rear_clay.png runtime_finial.png runtime_front_contact.png runtime_louvre_ridge.png runtime_louvre_ridge_rear_clay.png runtime_oriel.png runtime_oriel_rear_clay.png runtime_pillory.png runtime_pillory_rear_clay.png runtime_rear_contact.png runtime_sign_boot.png runtime_sign_boot_rear_clay.png runtime_sign_key.png runtime_sign_key_rear_clay.png runtime_sign_pig.png runtime_sign_pig_rear_clay.png runtime_sign_pretzel.png runtime_sign_pretzel_rear_clay.png runtime_thatch_panel.png runtime_thatch_panel_rear_clay.png runtime_thatch_ridge.png runtime_thatch_ridge_rear_clay.png runtime_well_wheel.png runtime_well_wheel_rear_clay.png runtime_window_cellar.png runtime_window_shuttered.png hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed exec /bin/bash -lc "cat /home/claude-agent/.agents/skills/blender-game-assets/reference/critic-loop.md; cat prepare_materials.py; rg -n 'thatch|tuft|xs=' build_kit.py; cat revision_scope.md" in /home/claude-agent/forge-build/forge-assets/jobs/medieval-town-v1 succeeded in 0ms: # 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.

Models use metres, +Y up, +Z facade outward, and X across the facade. Names, dimensions, bounding boxes, clear openings and placement exceptions are in `kit.json`. The source reference is `sheet.jpg`. ## Files - `kit.glb`: all twenty named nodes at their authored origins, with identity transforms. - `kit.json`: placement contract, budgets, dimensions and per-node material names. - `materials.json` and `materials/`: external PBR shelf, shared maps preserved byte-for-byte. Bind by exact material name. GLB contains geometry and material factors, without embedded images. - `kit.blend`: editable source geometry. `build_kit.py`, `geometry.py`, `details.py`, `prepare_materials.py`: reproducible builders. - `kit_sheet.png`: labelled atom contact sheet. `test_house.png`: rich house corner, cottage, pillory and wheel well. `test_house.glb`: the same assembly for loader testing. - `viewer/`, `browser_check.py`, `runtime_check.json`: actual Three.js loader, captures and measured draw counts. - `validation.json`, `audit_glb.json`: geometry/budget checks. `renders/`, `details_*.png`, `rear_*.png`: textured and clay evidence. ## Placement Facade atoms stay upright. The exterior host wall plane is Z=0. Door origins are bottom centre of the clear opening, with plank leaves recessed behind the wall and stone trim in front. Cut the declared opening out of the host wall; do not cover door leaves, barred openings, unglazed windows or bay interiors with a solid wall. `window_shuttered` has the same 0.7 × 1.0 m clear opening as `window_leaded`; open shutters project approximately 0.355 m. These are physical open leaves, not glass planes. `dormer_gabled` and `dormer_hipped` remain vertical, with their sill centre on the roof. Rotate around Y for roof orientation, **not around X to follow roof pitch**. The 55° host plane in atom space is `y = -tan(55°) * z`: positive Z points downslope. The cheeks and roofs extend behind the plane and bury into it. Front glazing stays above the slope. No host-roof cutout is needed for the delivered opaque glazing. Wall dormers instead anchor at the eaves, with their front at Z=0. `thatch_panel` is in slope space: X along the eaves, Y thickness away from rafters, Z downslope. Place its upper-edge origin at 1 m grid intervals, then rotate the whole grid to the roof pitch (50–55°). Actual panels overlap by 0.01 m in X and 0.04 m in Z; nominal grid units remain 1 × 1 m. Do not scale them apart. `thatch_ridge` repeats along X at 1 m intervals; its skirts descend below the ridge to cover panel tops. The test cottage has exactly three columns and two rows per side, plus three ridge rolls. Reed normal detail is derived from the same periodic analytic height field as the albedo, not an AO or geometry bake. Maps are 1024² with a 1 m surface repeat and 0.4 m cut-end repeat; PNG row derivatives are inverted for OpenGL +Y normal maps. Chimneys anchor bottom centre, with their base 0.55 m below the roof ridge. `louvre_ridge` and ridge rolls have ridge axis X. Signs anchor at the wall fixing point, hang below Y=0 and project into +Z. The oriel anchors at the storey floor on its back plane; corbels intentionally extend 0.43 m below that origin and at least 35 mm in front of the wall. Door surrounds project 175 mm, avoiding facade z-fighting. Nominal envelopes guide placement; consult actual bounding boxes for culling. Small bargeboard/bevel overhangs and below-origin supports are retained, rather than distorting the frozen anchors to force an axis-aligned nominal box. ## Materials and loader Use existing shelf names; `Thatch_reed`, `Thatch_reed_cut` and `Leather_brown` are original additions. The cut material supplies hollow stalk ends on eaves and verges. UV0 already contains the physical repeat scale: set texture repeat to 1, wrap both axes, load base colour as sRGB and normal/ORM as linear. For glTF external maps use `flipY=false`. ORM channels are ambient occlusion, roughness, metallic. Copy UV0 to the AO UV channel when required by the renderer. `Door_paint` and `Sign_paint` remain recolourable. The source geometry is deliberately authored Y-up in Blender and exported with `export_yup=False`. Blender imports the delivered GLB into its usual Z-up workspace for rendering. The render script handles that conversion; never apply it a second time in the game. ## Rebuild and checks ```sh python3 prepare_materials.py blender -b --factory-startup --python-exit-code 1 --python build_kit.py blender -b --factory-startup --python-exit-code 1 --python render_kit.py blender -b --factory-startup --python-exit-code 1 --python bind_source_materials.py python3 make_sheet.py python3 validate_kit.py python3 browser_check.py ``` `validate_kit.py` uses the installed Forge `audit_glb.py`. The strict generic audit flags identical primitives reused by the two different dormer atoms. This is an explicitly checked cross-node reuse, not duplicated surfaces inside one atom. No zero-area triangles or non-finite attributes are accepted. Browser metrics are measured main-pass counts; software Chromium timings are not representative of a game GPU. Roof-cover/eaves-system contract sections are excluded per this task's brief. ## Visual review The reed revision adds weathered directional albedo and registered normals, scalloped eaves with hollow stem ends, and bent hazel ridge spars. The board-free boot uses dark `Leather_brown` with its lighter sole edge. Frozen atom frames and budgets remain unchanged. See `critic_final.txt` for the current visual review. The delivered louvre has three physical slats per long side with open gaps; its feet embed at the ridge. { "status": "PASS", "glb_sha256": "62f70c65f3f111465c76d8ece4cdf48567144d5758e838dbef905e995839f547", "frozen_names": 20, "triangles": 25072, "budget": 45000, "per_atom": { "dormer_gabled": 1444, "dormer_hipped": 1778, "dormer_wall": 1840, "louvre_ridge": 740, "chimney_cluster": 2352, "chimney_twin": 360, "sign_boot": 756, "sign_pig": 948, "sign_key": 856, "sign_pretzel": 884, "oriel": 1956, "door_arched_stone": 1132, "door_cellar": 1132, "window_cellar": 316, "window_shuttered": 1036, "finial": 210, "thatch_panel": 298, "thatch_ridge": 246, "pillory": 2356, "well_wheel": 4432 }, "nonfinite": 0, "zero_area": 0, "identity_node_transforms": true, "dormer_rear_buried_on_55_degree_roof": true, "shared_texture_files_identical": 33, "documented_audit_exception": [ { "primitive": "dormer_hipped[1]", "same_as": "dormer_gabled[1]" }, { "primitive": "dormer_hipped[4]", "same_as": "dormer_gabled[5]" } ], "audit_exception_reason": "Separate dormer atoms intentionally reuse identical component geometry.

The UI shows a "Clay" toggle button, confirming the current view is textured mode, not clay. - **renders/sign_boot.png**: Hanging metal bracket holding a brown boot silhouette without a backboard. It has thin wooden battens pinned across the top cuff and bottom edge, but no lighter-colored sole. - **details_thatch_grid.png**: Half-textured, half-unlit split diagnostic view showing the cottage thatch geometry and material mapping. --- ### Verification of previous critic claims | Prior claim | Pixel evidence | Fact check | | :--- | :--- | :--- | | Ridge has no bindings | Three distinct 3D binding straps wrap across the ridge in both `thatch_ridge.png` and `runtime_assembly_cottage.png`. | **FALSE** | | Runtime image was clay | Full PBR materials are visible (timber, plaster, reed, stone). The UI button reads "Clay" as a toggle target. | **FALSE** | --- ### Requirements check - **Passed**: - Directional grey-brown reed thatch. - Hazel bindings physically modeled on the roof ridge. - Thick cut-stem eave cross-sections with circular reed textures. - Board-free hanging boot sign (no rectangular backing plate). - **Substantive findings**: 1. **Boot lacks lighter sole**: The boot body is uniform reddish-brown; there is no contrasting lighter leather layer on the bottom tread. 2. **Stray batten strips on boot**: Thin mounting strips run along the boot cuff and sole edge instead of a clean standalone cut boot. 3. **Thatch panel bundling is uniform**: Bundles use regular triangular pitch waves rather than organic, irregular clump variation. --- ### Verdict **REVISE** (boot requires lighter sole texture/geometry and removal of edge battens; thatch meets core structural and binding requirements). hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed hook: PreToolUse Completed exec /bin/bash -lc "cat > critic_final.txt <<'EOF' FINAL REVISION REVIEW — technical PASS; visual REVISE Root author inspected the actual final PNGs: details_thatch_grid.png, renders/thatch_panel.png, renders/thatch_ridge.png, runtime_assembly_cottage.png, runtime_sign_boot.png, kit_sheet.png, test_house.png. Independent reviews are retained verbatim in critic_revision.txt (Haiku) and critic_followup.txt (Gemini). Both return REVISE, but contain factual image-reading errors; neither is adopted wholesale. Confirmed improvements: weathered grey-brown directional reed albedo and aligned normal maps; thick cut-stem cross-section; small eave tufts; three visible hazel bindings per ridge; board-free dark brown boot with existing lighter sole edge. Remaining: reed strands remain overly continuous/regular, and the eave silhouette is scalloped rather than convincingly shaggy. These are visual shortcomings, not technical validation failures. The three-revision skill cap is reached; no claim of full visual acceptance is made. Review reconciliation: first review's missing-ridge-bindings and clay-runtime claims are disproved by the final images and the second review. Second review's 'half-unlit split diagnostic' claim misreads the ordinary light/shadow boundary. The boot's existing sole edge is visibly lighter than its dark leather body; removing its cuff/sole trim is not part of this revision's brief. Geometry and runtime: 298 triangles panel; 246 ridge; 25,072 kit. Twenty frozen names, identity node frames and declared placement contracts retained. No zero-area triangles or nonfinite attributes. All 33 original shared texture files identical. Measured asset-only draws: kit 61 -> 63, assembly 86 -> 92. Chromium SwiftShader captures verify material loading; no GPU performance claim.
