Revision 1 of YOUR kit in this directory (build_kit.py, medieval-hero-houses.glb, lineup.png, final_<n>.png, NOTES.md;
the first brief is PROMPT.txt: every rule there still holds: names, frames, exact sizes, shared materials, budgets,
Blender on gex44 at /root/fal-author/medieval-hero-houses-v1). rev0/ keeps the current version.
The operator's bar is the Breton house (breton_reference.png): it reads REAL because it is old. Your six houses are well
built but read clean and new next to it. Look at lineup.png and breton_reference.png side by side first, then make them OLD
and LIVED IN, all through geometry, vertex colours (COLOR_0) and the shared shelf (one more shared material allowed):
1. Wear: rain streaks under sills, beams and eaves; a damp dark band at the wall foot (0 to 0.8 m) with green tint on the
   shady side; patches where plaster has fallen off showing the stone or brick behind (real insets with the rubble/brick
   material, 2-4 per plastered house); plaster not flat (gentle bulges); oak frames silvered grey where the rain hits,
   darker under the jetties; stronger sag of ridges and jetty lines; tiles and slates uneven with a few slipped or
   missing ones, moss in valleys and along the lower courses, lichen on slate; soot above the chimney tops and the
   bakery oven mouth.
2. Life at the fronts: window boxes with plants on two houses, some shutters open at different angles, goods on the shop
   counter (cloth bolts, baskets) and loaves on the bakery hatch, a hanging board sign (painted symbol, no words) on the
   shop and the bakery, a lantern on a bracket by two doors, a gutter + downpipe on two houses, a worn stone step.
3. Windows: leaded glass that reflects a little sky and shows a faint warm interior, not black holes.
Keep each house within 70k triangles, the kit within 350k and 25 MB. Export atomically (write a temp GLB, then move it
over medieval-hero-houses.glb) so the file is valid at every moment. Re-render lineup.png and final_<n>.png, update
NOTES.md (say what changed). Hard stop at 01:27 CET: whatever is finished by then must be exported.

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

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

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

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

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

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

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

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

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

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

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

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

## Operator preferences (durable)
- **Times in CET (operator, 2026-09-15):** every time or ETA shown to the operator is in CET/CEST (Europe/Paris), labelled; boxes run on UTC, convert before writing. Applies to worker briefs and published docs too.
- **Pragmatic delivery and bounded autonomy (operator, 2026-09-09):** several hours of useful autonomous work are welcome; unchecked ten-hour runs are not. Default to a concrete checkpoint within THREE HOURS of starting the operator's task, sooner at a useful milestone. Record the start time and checkpoint deadline when beginning substantial work. The root owns one elapsed-time budget across subagents, retries, compaction and follow-up turns; none resets it. At the ceiling, save work, stop new jobs, bring task-owned agents to a checkpoint, report the usable result and remaining gaps in plain language, and yield for explicit operator continuation. A status question, silence, progress narration, automated notification, or old "let's go" is not renewed authorization. The operator may explicitly set a different window.
- **Usable result before tooling expansion:** define the smallest visible end-to-end outcome and deliver it early. Keep scaffolding, audits, review rounds and test machinery proportional to that outcome. Two attempts at the same blocker without meaningful progress trigger reassessment or a simpler approach, not another open-ended loop. Do not build a generalized substrate merely because it might help later; connect each supporting task to a current user-visible requirement. Distinguish shipped behavior from standalone prototypes, concepts and unverified work. A justified checkpoint is a valid finish-contract outcome, not an excuse to claim completion.
- **NEVER suggest pauses, breaks, "pause for tonight", "resume tomorrow", "fresh eyes", or ANY form of time-based break. EVER.** This is the single most annoying behaviour for the operator. *Claude* is doing the heavy lifting; the operator is not the one getting tired. Time of day is irrelevant — push through, period. Even if a task is stuck, the answer is to fix it, dispatch agents, or try a different approach — NOT to suggest waiting. If a clean reinstall is the answer, just do it. The operator decides when to stop, not Claude.
- **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 <repo> --purpose <task> --task <brief>` 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 <proxy alias>` |
| (none) | Claude Haiku 5.5 (`claude-haiku-5-5`, via `claude-lean`) | `haikux` | Claude Code flags (`--effort low`, `--tools ""`) |

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

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

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

**Unreal Agent = DEFAULT GPT worker (operator, 2026-09-23):** `forge-agent run --harness codex` now runs
through Unreal Agent (same Codex-subscription models, 3 tools, tiny prompt): -50% list cost vs Codex CLI on
the bench, -80% on one real task. Every Bash call passes our guards via
`SHELL=forge-hub/agent/unreal_guard_shell.py`. No 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 <path>] [--task "what was asked"]`;
default reviewer gemini, cross-check with `--by deepseek`. Reviews uncommitted
work, else the last commit, else the root commit. Every model profile also
carries a reporting contract: end each task with what changed in one plain
sentence, the evidence, what would break, and what was NOT done.

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

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

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

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

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

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 <repo>`, or `git worktree remove <path>`
  without `--force`: commits stay on the branch); `/tmp` staging/preview/publish copies and test builds; browser
  profiles; downloaded zips already unpacked; docker images/containers you built for a test; big renders/videos
  already pushed onward; stopped dev servers and ssh tunnels you started.
- **Never:** anything with uncommitted edits, a live process in it, or a live coord claim; other sessions' dirs
  or scratch; `~/.claude` transcripts, `~/.codex/sessions`, `~/.cache/ms-playwright`, model caches; deployed apps.
  If unsure whose it is, leave it and `coord note` it.
- **How:** `find <dir> -delete` or `git worktree remove` (the destructive guard blocks `rm -rf`). Check
  `df -h /` when you finish; under 15 GB free, say so in your report.
- **Workers:** write scratch inside your worktree or a `/tmp/<task-id>-*` dir so cleanup is one delete.
- Memory `feedback_clean_up_after_yourself.md`.

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

## Multi-Claude coordination (durable)

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

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

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

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

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

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

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

## Finish contract (harness)

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

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

# Blender game assets, headless

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

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

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

## Read only what the task needs

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

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

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

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

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

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

## Which representation: decide before modelling

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

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

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

## 1. The recipe

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

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

## 2. Headless setup on gex44

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

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

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

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

## 3. Modelling: loft, recess, greeble

Three techniques, in order of impact.

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

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

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

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

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

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

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

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

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

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

## 5. Rocks and foliage

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

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

## 6. Materials

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

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

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

## 7. Lighting and camera

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

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

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

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

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

## 8. Export contract for three.js

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

## 9. Traps

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

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

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

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

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

# 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.

carries a reporting contract: end each task with what changed in one plain
sentence, the evidence, what would break, and what was NOT done.

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

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

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

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

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

## 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 <repo>`, or `git worktree remove <path>`
  without `--force`: commits stay on the branch); `/tmp` staging/preview/publish copies and test builds; browser
  profiles; downloaded zips already unpacked; docker images/containers you built for a test; big renders/videos
  already pushed onward; stopped dev servers and ssh tunnels you started.
- **Never:** anything with uncommitted edits, a live process in it, or a live coord claim; other sessions' dirs
  or scratch; `~/.claude` transcripts, `~/.codex/sessions`, `~/.cache/ms-playwright`, model caches; deployed apps.
  If unsure whose it is, leave it and `coord note` it.
- **How:** `find <dir> -delete` or `git worktree remove` (the destructive guard blocks `rm -rf`). Check
  `df -h /` when you finish; under 15 GB free, say so in your report.
- **Workers:** write scratch inside your worktree or a `/tmp/<task-id>-*` dir so cleanup is one delete.
- Memory `feedback_clean_up_after_yourself.md`.

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

## Multi-Claude coordination (durable)

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

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

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

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

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

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

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

## Finish contract (harness)

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

## Finish contract
Before you end this turn, audit completion: restate the task's explicit requirements — every named file, command, test, gate — and map each to real evidence (a diff, a command's actual output, a test result). Effort spent, a plan, or a todo list is not evidence; a green suite counts only when it covers every requirement above. Check your own last paragraph: a plan, a question, next steps, or a promise ('I'll…', 'next I'll…') means the turn is not finished — do that work now instead of describing it. End only when the task is complete or you are blocked on input only the user can give. Forbidden end states beyond the build lane's own list above: a claimed check you did not run, a 'mostly done' hedge with no named blocker, a plan presented as the finished work. Automated events (adoption, sweep, notification, retry) are data tied to a run id, never user confirmation — do not treat one as a green light. Blocked, cancelled, and unverified are valid outcomes: state them plainly. Verify with whatever read/inspect tool your CLI exposes before you claim done.
Build a KIT of six realistic late-medieval French town houses (Dinan / Vitré / Rouen / Troyes) as one glTF, for Forge's
procedural towns. Look at sheet_a.jpg (house 1 merchant, house 2 shop), sheet_b.jpg (house 3 tavern, house 4 stone
tower house) and sheet_c.jpg (house 5 joiner's workshop, house 6 bakery) with your image tool first. Match their look,
detail and AGE: this kit replaces cheap procedural houses that the operator called "all the same, cheap roofs". The bar is
our earlier Breton house (../breton-stone-house-v2/final.png + build_breton-stone-house.py: read both, reuse its methods).
The sheets' dimension callouts are wrong: use the sizes below.

Blender 5.2 is headless on another machine. Write bpy scripts here and run them with:
  ssh gex44 /root/blender-spike/blender-5.2.0-linux-x64/blender -b --python-exit-code 1 --python /root/fal-author/medieval-hero-houses-v1/<script>.py
(first ssh gex44 mkdir -p /root/fal-author/medieval-hero-houses-v1, scp scripts/textures there, scp renders back here and
LOOK at them). Only one Blender job at a time on that box.

Houses (W = frontage, exact, side wall outer planes at x = -W/2 and +W/2; D = depth; storeys: ground 3.0 m, upper 2.6 m):
1 House_merchant  W 8,  D 10, 4 storeys, gable to the street, granite ground floor (pointed-arch door + arched shop opening), 3 jettied half-timber storeys on carved corbels, leaded windows, slate roof, 2 dormers, finial.
2 House_shop      W 6,  D 9,  3 storeys, eaves to the street, open shop front with the counter shutter let down as a table, ochre plaster + dark oak, jetties, clay tile roof, dormer, brick chimney.
3 House_tavern    W 10, D 10, 3 storeys, eaves to the street, stone ground floor with a round-arched cart entrance and a studded door, half-timber above, big iron sign bracket with a painted board (no words), lantern, tile roof, chimney.
4 House_tower     W 5,  D 8,  4 storeys, gable to the street, dressed granite + rubble, mullioned windows, oriel on the 2nd floor, slate roof, tall chimney.
5 House_joiner    W 7,  D 9,  2 storeys + attic, eaves to the street, timber workshop ground floor with plank shutters hinged up and a workbench inside, whitewashed half-timber storey, dormer, worn tile roof with a few missing tiles.
6 House_bakery    W 6,  D 9,  2 storeys, gable to the street, rubble + lime plaster, round bread oven bulging out of the front (at most 1.8 m in front of the facade) with its own little tile roof, hatch counter, smoke-stained chimney.
Every house: front facade toward +Z; origin (0,0,0) on the ground at the CENTRE OF THE FRONT WALL LINE (the house
extends toward -Z; jetties, steps, oven, sign may stick out in front up to 1.8 m); ground floor level y = 0; a granite
plinth/foundation that continues DOWN to y = -1.5 under the whole footprint (hidden on flat ground, shows on slopes).
Side walls are party walls (houses stand wall to wall), plain stone or plaster but textured and aged, because they show
above lower neighbours. Back facade simpler but real (a door, windows). Real interiors are NOT needed: openings show a dark
room (a recessed dark plane 0.4 m behind, never see-through). Doors, steps, sills, corbels, beams, tiles and slates as
geometry where they catch light; bevelled edges; leaning timbers, a slightly sagging ridge, uneven eaves; nothing floating,
no z-fighting.

ONE shared material shelf for all six (this is a kit: the same granite / oak / plaster / tile / slate / rubble / iron /
glass materials, at most 10 materials in total): photographic CC0 Poly Haven textures (dl.polyhaven.org, 1k or 2k jpg;
list every id in NOTES.md) with node detail (moss on roofs, grime at the wall foot, rain streaks, edge wear), baked with
Cycles to TILEABLE image textures (base colour, normal, ORM), max 1024 px (ORM 512), world-scale UVs (about 1 texture repeat
per 2 m) so every house shares them. Per-house variety and ageing goes in vertex colours (COLOR_0, multiplied with base
colour: AO in corners and under eaves, moss and soot patches, plaster tint) so no house needs its own images. Each house
also gets a second plaster or tile tint via vertex colour so the six do not look like one paint pot.
Budget: 30k to 70k triangles per house, whole kit <= 350k, GLB <= 25 MB.

Export: medieval-hero-houses.glb (binary, Y up, metres, transforms applied, no cameras/lights): six root nodes named
exactly as above, laid out side by side 14 m apart along X in the file (their positions are ignored by code; each root's
children are in the house's own frame relative to the root). Under each root: the meshes, plus empties Entrance (on the
ground 0.8 m in front of the main door) and Door (centre of the main door bottom).
Work INCREMENTALLY: build_kit.py builds all houses done so far and exports; re-export after each finished house, so a
usable partial kit always exists. Deliver here: medieval-hero-houses.glb; build_kit.py (one clean run from an empty scene
makes the GLB); lineup.png (1920x1080 Cycles, the six in a row as a street, soft daylight); final_<n>.png (each house 3/4
front); clay_lineup.png; nodes.json (per root: bounding box in its own frame, triangle count); NOTES.md (6 lines).
Hard stop at 01:46 CET: by then the GLB holds every house you finished. Quality over count: 4 excellent houses beat 6
cheap ones. Order: 1, 2, 3, 5, 4, 6.
Late-medieval French kit: 6 houses; exact frontage/depth, metre units, +Y up / +Z front; origins at front-wall centre; 1.5 m foundations.
285,424 triangles; 24,507,856 GLB bytes; 9 shared PBR materials; COLOR_0 multiplies baked base colour.
Poly Haven CC0 texture ids: medieval_red_brick, metal_plate_02, rock_wall_09, roof_tiles_14, slate_floor_03, wooden_planks, worn_plaster_wall, worn_rock_natural_01; https://polyhaven.com/license; sources dl.polyhaven.org, jpg/1k.
Cycles shared tileable swatch bakes: base/normal <=1024, packed ORM 512; registered 2 m UVs; periodic patina nodes; spatial vertex grime, moss, beam contact shading and plaster/tile tints.
Build: Blender 5.2 -b --python-exit-code 1 --python build_kit.py; -- --count N for incremental order 1,2,3,5,4,6; scans/bakes cached beside script; every completed house exports atomically.
Deliverable GLB is reimported for Cycles hero/clay/lineup renders; dark recessed rooms are closed; rear facades authored; structural audit and visual review recorded separately.

# 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

codex
The Breton reference gets much of its age from damp masonry, uneven roof courses and worn pale stone. In the lineup, the repeated clean plaster panels and uniformly dark windows stand out. I’m using the Blender game-assets and construction-kit skills to make the wear follow water, shelter and use.

# 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.

# Preflight and Recovery

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

## Exercise the actual execution path first

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

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

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

## Keep stages independently recoverable

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

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

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

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

## Validate a candidate before replacing delivery assets

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

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

# Author and critic loop for a Blender asset

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

## Seats

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

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

## Budget

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

## Before the first render

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

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

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

## Each revision keeps

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

## The critic pass

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

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

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

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

## Rules that stop false passes

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

## Lessons

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

Authored game-mesh reconstruction of sheet_a/b/c; target detail/age: ../breton-stone-house-v2/final.png. Metres, Y-up export, front +Z; photographic Poly Haven CC0 shared shelf.
Cameras: 1920x1080 three-quarter front for every house; rear check and close merchant/tower detail; street lineup and identical clay view; imported GLB is the render source.
Budget: 30–70k triangles per house, <=350k total, <=25 MB GLB, <=10 shared materials, base/normal <=1024 and ORM512. Target <=9 material draws per house. Actual runtime counters are measured separately from offline estimates.
Three revision cap, at most two independent critic passes per revision. First merchant export is revision0; geometry-contract and material corrections are revision1.
Outputs: medieval-hero-houses.glb, final_1..6.png, lineup.png, clay_lineup.png, nodes.json, NOTES.md, audit evidence. No claim of Forge in-game integration without an actual runtime capture.

codex
The existing kit is close to two limits: the merchant is at 69,990 triangles, and the GLB is 24.5 MB. I’ll simplify the tiny lead cames to make room for recessed plaster damage and front-of-house props. The new weathering will use vertex colours tied to sills, eaves and ground contact.

The ageing and prop additions are in the builder: cut-out plaster losses with recessed masonry, damp and runoff colours, angled shutters, planted boxes, shop goods and wordless signs. I’m checking the first full build now; the renders will show whether the wear is strong enough at street scale.

Revision 1 started 00:19 CEST, 9 October 2026; hard delivery checkpoint 01:27 CEST (Europe/Paris, operator's CET label).
Preserve rev0/; modify builder and atomically replace GLB after each finished house. Six exact named roots and frames, 30–70k triangles per house, <=350k kit, <=25,000,000 bytes, <=10 shared materials. No unique house textures.
New geometry/vertex-colour wear and street life per PROMPT-r1.txt; original PROMPT.txt still applies. Camera/lighting stay matched to rev0. Inspect reimported GLB Cycles lineup, individual fronts, rear views and clay; measure exported Three.js runtime separately.
Bounded correction passes: first complete build, visual correction, final validation. Preserve full build log, GLB contract audit, runtime captures and six-line NOTES.md.

Revision 1 started 00:19 CEST, 9 October 2026; hard delivery checkpoint 01:27 CEST (Europe/Paris, operator's CET label).
Preserve rev0/; modify builder and atomically replace GLB after each finished house. Six exact named roots and frames, 30–70k triangles per house, <=350k kit, <=25,000,000 bytes, <=10 shared materials. No unique house textures.
New geometry/vertex-colour wear and street life per PROMPT-r1.txt; original PROMPT.txt still applies. Camera/lighting stay matched to rev0. Inspect reimported GLB Cycles lineup, individual fronts, rear views and clay; measure exported Three.js runtime separately.
Bounded correction passes: first complete build, visual correction, final validation. Preserve full build log, GLB contract audit, runtime captures and six-line NOTES.md.

Build a KIT of six realistic late-medieval French town houses (Dinan / Vitré / Rouen / Troyes) as one glTF, for Forge's
procedural towns. Look at sheet_a.jpg (house 1 merchant, house 2 shop), sheet_b.jpg (house 3 tavern, house 4 stone
tower house) and sheet_c.jpg (house 5 joiner's workshop, house 6 bakery) with your image tool first. Match their look,
detail and AGE: this kit replaces cheap procedural houses that the operator called "all the same, cheap roofs". The bar is
our earlier Breton house (../breton-stone-house-v2/final.png + build_breton-stone-house.py: read both, reuse its methods).
The sheets' dimension callouts are wrong: use the sizes below.

Blender 5.2 is headless on another machine. Write bpy scripts here and run them with:

(first ssh gex44 mkdir -p /root/fal-author/medieval-hero-houses-v1, scp scripts/textures there, scp renders back here and
LOOK at them). Only one Blender job at a time on that box.

Houses (W = frontage, exact, side wall outer planes at x = -W/2 and +W/2; D = depth; storeys: ground 3.0 m, upper 2.6 m):
1 House_merchant  W 8,  D 10, 4 storeys, gable to the street, granite ground floor (pointed-arch door + arched shop opening), 3 jettied half-timber storeys on carved corbels, leaded windows, slate roof, 2 dormers, finial.
2 House_shop      W 6,  D 9,  3 storeys, eaves to the street, open shop front with the counter shutter let down as a table, ochre plaster + dark oak, jetties, clay tile roof, dormer, brick chimney.
3 House_tavern    W 10, D 10, 3 storeys, eaves to the street, stone ground floor with a round-arched cart entrance and a studded door, half-timber above, big iron sign bracket with a painted board (no words), lantern, tile roof, chimney.
4 House_tower     W 5,  D 8,  4 storeys, gable to the street, dressed granite + rubble, mullioned windows, oriel on the 2nd floor, slate roof, tall chimney.
5 House_joiner    W 7,  D 9,  2 storeys + attic, eaves to the street, timber workshop ground floor with plank shutters hinged up and a workbench inside, whitewashed half-timber storey, dormer, worn tile roof with a few missing tiles.
6 House_bakery    W 6,  D 9,  2 storeys, gable to the street, rubble + lime plaster, round bread oven bulging out of the front (at most 1.8 m in front of the facade) with its own little tile roof, hatch counter, smoke-stained chimney.
Every house: front facade toward +Z; origin (0,0,0) on the ground at the CENTRE OF THE FRONT WALL LINE (the house
extends toward -Z; jetties, steps, oven, sign may stick out in front up to 1.8 m); ground floor level y = 0; a granite
plinth/foundation that continues DOWN to y = -1.5 under the whole footprint (hidden on flat ground, shows on slopes).
Side walls are party walls (houses stand wall to wall), plain stone or plaster but textured and aged, because they show
above lower neighbours. Back facade simpler but real (a door, windows). Real interiors are NOT needed: openings show a dark
room (a recessed dark plane 0.4 m behind, never see-through). Doors, steps, sills, corbels, beams, tiles and slates as
geometry where they catch light; bevelled edges; leaning timbers, a slightly sagging ridge, uneven eaves; nothing floating,
no z-fighting.

ONE shared material shelf for all six (this is a kit: the same granite / oak / plaster / tile / slate / rubble / iron /
glass materials, at most 10 materials in total): photographic CC0 Poly Haven textures (dl.polyhaven.org, 1k or 2k jpg;
list every id in NOTES.md) with node detail (moss on roofs, grime at the wall foot, rain streaks, edge wear), baked with
Cycles to TILEABLE image textures (base colour, normal, ORM), max 1024 px (ORM 512), world-scale UVs (about 1 texture repeat
per 2 m) so every house shares them. Per-house variety and ageing goes in vertex colours (COLOR_0, multiplied with base
colour: AO in corners and under eaves, moss and soot patches, plaster tint) so no house needs its own images. Each house
also gets a second plaster or tile tint via vertex colour so the six do not look like one paint pot.
Budget: 30k to 70k triangles per house, whole kit <= 350k, GLB <= 25 MB.

Export: medieval-hero-houses.glb (binary, Y up, metres, transforms applied, no cameras/lights): six root nodes named
exactly as above, laid out side by side 14 m apart along X in the file (their positions are ignored by code; each root's
children are in the house's own frame relative to the root). Under each root: the meshes, plus empties Entrance (on the
ground 0.8 m in front of the main door) and Door (centre of the main door bottom).
Work INCREMENTALLY: build_kit.py builds all houses done so far and exports; re-export after each finished house, so a
usable partial kit always exists. Deliver here: medieval-hero-houses.glb; build_kit.py (one clean run from an empty scene
makes the GLB); lineup.png (1920x1080 Cycles, the six in a row as a street, soft daylight); final_<n>.png (each house 3/4
front); clay_lineup.png; nodes.json (per root: bounding box in its own frame, triangle count); NOTES.md (6 lines).
Hard stop at 01:46 CET: by then the GLB holds every house you finished. Quality over count: 4 excellent houses beat 6
cheap ones. Order: 1, 2, 3, 5, 4, 6.

codex
The first build hit the merchant house’s triangle limit. I’m trimming hidden roof geometry to make room for the wear and planting, then checking the full kit’s size and renders.

28:- **local** `204.168.129.84` — orchestrator. Opus planning, this memory store, the `coord` bus. No app/infra runs here.
68:- **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.
69:- **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 <repo> --purpose <task> --task <brief>` 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.
76:(safety = the PreToolUse secret + coordination guards, not a sandbox):
95:store, coordination protocol, standing laws; `forge-hub/agent/harness_env.py`),
97:memory/skills/coordination. Docs: `forge-hub/agent/DEEPSEEK.md`, `GEMINI.md`.
174:- Task agents from Claude, GPT, Gemini or DeepSeek: `forge-agent run --harness deepseek --model deepseek-flash --repo <git-repo> --purpose <task> --task <brief> --timeout 900`. Same isolated worktrees, shared Forge MCP memory/skills/coord, hooks and finish rules. DeepSeek orchestrators can call the other `forge-agent` harnesses; workers do not recursively delegate.
175:- 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.
199:- **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)
212:- **Never:** anything with uncommitted edits, a live process in it, or a live coord claim; other sessions' dirs
214:  If unsure whose it is, leave it and `coord note` it.
226:## Multi-Claude coordination (durable)
228: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.
231:1. `coord check <host:path>` — is anyone else on it? (exit 3 = conflict)
232:2. `coord claim <host:path> [--note "..."]` — take it (exclusive; auto-expires, TTL 30m, refreshed by heartbeat).
233:3. Do the work, then `coord release <host:path>` (or `--all`).
234:4. `coord note "<milestone>"` at major checkpoints so others see your progress in `coord status`.
239:- The guard fails OPEN — if `coord` errors it never blocks your tools. It only bites on a real, live, conflicting claim.
240:- If you're BLOCKED, check `coord status`, coordinate via `coord note`, or wait for release. Override only after confirming with the other session.
243:**Multi-agent claims (2026-09-05):** sibling subagents forked from one session share ONE coord identity (the ancestor-pid walk can't tell them apart) — always claim/release with `--owner <task-tag>` when you're one of several agents on the same session. Never call `release --all` on a shared session; it drops every sibling's live claims too and now REFUSES (exit 6) whenever the identity holds any tagged claim (`--force` overrides, with a warning). Forge-agent workers (`forge_agent.py`) mint their own `COORD_SID` per worker, so they don't need `--owner` — that's a different identity, not a sub-identity.
255:  (see `~/.agents/skills` for the list), and `coord_check` before writing
268:  the box's secret/destructive/coord/deploy-host/mirror guards over BOTH
273:- **Claim before you write.** The coord protocol above (`coord check` /
274:  `coord claim` / `coord release`) is not Claude-specific — it is the shared
276:  might also touch. If your harness can shell out, use the `coord` CLI
280:  share one coord identity (one `COORD_SID`), always claim/release with
281:  `--owner <task-tag>` — never `release --all`, which now REFUSES (exit 6)

# 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.

All six houses now fit their triangle budgets. The added detail pushed the file over 25 MB, so I’m storing normals at 16-bit precision to reduce size without removing visible geometry. Next I’ll check the reimported GLB in Cycles and Three.js.

The first renders show the silvered timber, damp stonework, uneven roofs and brighter glass. Some plaster damage is hidden behind the window trim; I’m moving those patches onto exposed panels so they read clearly from the street.

**Verdict: REVISE.** The rev0 comparison is BLOCKED: `rev0/final_1.png` doesn't exist (Read returned "File does not exist"), and I'm limited to Read, so I couldn't list the folder. I saw the reference and the current `final_1`, `final_2` and `final_5` (1920×1080 coordinates below).

**Findings, by priority**

1. **Side-wall plaster looks like a flat sheet of paper.**
   - Evidence: `final_1` wall at x1090–1370, y400–950, `final_2` at x1050–1350, y450–950, and `final_5` at x1100–1440, y300–870 are all near-uniform fill. Stone shows only at the torn silhouette edges and bottom strip (`final_5` x1110–1330, y790–880).
   - `final_5` gable (x1120–1330, y230–400) has blocky 20–40 px squares, a texture artifact.
   - I agree with moving the losses into visible panel gaps, but that alone won't fix a blank 300×550 px wall.
   - Fix: scatter patches across the open wall field, with a stepped recessed edge. Add a damp gradient and mottling.
   - Accept:
     - Each large wall has at least 5 separate loss patches, each covering 2–8% of the wall.
     - At least 40% of the patches sit away from borders and trims.
     - Stone shows 1–3 cm below the plaster face.
     - The bottom 25% of the wall is at least 12% darker than the top.
     - Plaster luminance standard deviation is 0.05 or more.
     - No visible texel blocks larger than 6 px at 1080p.

2. **There is no weathering story: no rain streaks, soot or damp.**
   - Evidence: nothing runs down from the sills, sign bracket, eaves or the `final_2` chimney (x1100–1200, y10–130). The only "damp" is a green skirt (`final_1` x650–1390, y985–1030).
   - Fix: add vertical streak decals below every projecting element, soot above openings and around the chimney, and a damp band at the base.
   - Accept: 8 or more visible streaks per facade, 80–300 px long, 8–15% darker than the surrounding wall. Soot is visible on every chimney and above at least 2 openings.

3. **The roofs read as saturated and cloth-warped, not old and grey-oak.**
   - Evidence: `final_2` and `final_5` roofs are bright terracotta, and `final_1` is saturated green. The ridge wave (`final_1` x1000–1390, y340–390) looks like a mesh warp, with tiles crossing each other.
   - The holes (`final_1` x1045, y340; `final_2` x90, y260; `final_5` x1050, y350) are pure black rectangles.
   - Fix: desaturate the tile body and use moss in patches. Make the sag smooth and carry it into the eave and gutter line. Show battens or underlay through the holes.
   - Accept:
     - Mean tile saturation is 0.35 or less.
     - Moss covers no more than 25% of the roof.
     - Tile courses stay parallel.
     - Holes show a brown or dark value above RGB 25, not black.
     - The eave deflects at least 1.5% of its span, following the ridge.

4. **Dressing, glass and sky are uneven across the three houses.**
   - **`final_1`:** no lantern, sign, goods, gutter, downpipe or chimney. Plants are one tiny box (x810–890, y785–805).
   - **`final_2` and `final_5`:** these have a sign, lantern, goods, a flower box, a downpipe and a plank. The shop interiors are flat black voids (`final_2` x790–1000, y850–960; `final_5` x640–850, y690–870).
   - **Glass:** it reads cool blue-grey with a brown lower half (`final_1` x680–1010, y440–490), which looks like dirt, not warmth.
   - **Sky:** the background is a plain grey gradient.
   - Fix: give each house at least one sign or lantern, 2 goods or plant items, and a gutter with a downpipe. Give the voids a back wall, shelves and a warm interior. Warm about a third of the panes, and add a sky gradient.
   - Accept:
     - At least 30% of panes have a warm tint, with hue 25–40° and value 20–35% above the cool panes.
     - No shop interior is darker than RGB 15.
     - The background shows a visible top-to-horizon gradient.

5. **Style and material realism versus Breton.**
   - **Breton reference:** it sells age through a rubble texture across the whole wall, crisp granite quoins, bevelled trims, slate-blue roof and clean metal gutters.
   - **These models:** they are tinted flat colour. The ochre plaster (`final_2`) is cartoon-saturated, and trims have little bevel or contact shadow. Grey oak is the one thing that works.
   - Candidly, the timber-frame typology is fine, but the material finish is below the reference.
   - Fix: lower plaster saturation, add a bevel and contact darkening at trim and wall junctions, and raise texture density.
   - Accept:
     - Plaster mean saturation is 0.25 or less.
     - Texture density is 512 px/m or more.
     - All trim edges show a highlight on 1080p renders.
     - Contact darkening of at least 10% appears at wall and trim junctions.

**Regressions versus rev0:** unverifiable. Please give me a path that exists to check.

# Author and critic loop for a Blender asset

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

## Seats

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

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

## Budget

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

## Before the first render

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

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

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

## Each revision keeps

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

## The critic pass

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

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

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

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

## Rules that stop false passes

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

## Lessons

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

The final correction pass is rendering now. The side-wall plaster losses now sit clearly behind the plaster surface, with broken edges, and the weathering follows the sloping eaves. I’m checking the exported model and regenerated views next.

Build a KIT of six realistic late-medieval French town houses (Dinan / Vitré / Rouen / Troyes) as one glTF, for Forge's
procedural towns. Look at sheet_a.jpg (house 1 merchant, house 2 shop), sheet_b.jpg (house 3 tavern, house 4 stone
tower house) and sheet_c.jpg (house 5 joiner's workshop, house 6 bakery) with your image tool first. Match their look,
detail and AGE: this kit replaces cheap procedural houses that the operator called "all the same, cheap roofs". The bar is
our earlier Breton house (../breton-stone-house-v2/final.png + build_breton-stone-house.py: read both, reuse its methods).
The sheets' dimension callouts are wrong: use the sizes below.

Blender 5.2 is headless on another machine. Write bpy scripts here and run them with:
  ssh gex44 /root/blender-spike/blender-5.2.0-linux-x64/blender -b --python-exit-code 1 --python /root/fal-author/medieval-hero-houses-v1/<script>.py
(first ssh gex44 mkdir -p /root/fal-author/medieval-hero-houses-v1, scp scripts/textures there, scp renders back here and
LOOK at them). Only one Blender job at a time on that box.

Houses (W = frontage, exact, side wall outer planes at x = -W/2 and +W/2; D = depth; storeys: ground 3.0 m, upper 2.6 m):
1 House_merchant  W 8,  D 10, 4 storeys, gable to the street, granite ground floor (pointed-arch door + arched shop opening), 3 jettied half-timber storeys on carved corbels, leaded windows, slate roof, 2 dormers, finial.
2 House_shop      W 6,  D 9,  3 storeys, eaves to the street, open shop front with the counter shutter let down as a table, ochre plaster + dark oak, jetties, clay tile roof, dormer, brick chimney.
3 House_tavern    W 10, D 10, 3 storeys, eaves to the street, stone ground floor with a round-arched cart entrance and a studded door, half-timber above, big iron sign bracket with a painted board (no words), lantern, tile roof, chimney.
4 House_tower     W 5,  D 8,  4 storeys, gable to the street, dressed granite + rubble, mullioned windows, oriel on the 2nd floor, slate roof, tall chimney.
5 House_joiner    W 7,  D 9,  2 storeys + attic, eaves to the street, timber workshop ground floor with plank shutters hinged up and a workbench inside, whitewashed half-timber storey, dormer, worn tile roof with a few missing tiles.
6 House_bakery    W 6,  D 9,  2 storeys, gable to the street, rubble + lime plaster, round bread oven bulging out of the front (at most 1.8 m in front of the facade) with its own little tile roof, hatch counter, smoke-stained chimney.
Every house: front facade toward +Z; origin (0,0,0) on the ground at the CENTRE OF THE FRONT WALL LINE (the house
extends toward -Z; jetties, steps, oven, sign may stick out in front up to 1.8 m); ground floor level y = 0; a granite
plinth/foundation that continues DOWN to y = -1.5 under the whole footprint (hidden on flat ground, shows on slopes).
Side walls are party walls (houses stand wall to wall), plain stone or plaster but textured and aged, because they show
above lower neighbours. Back facade simpler but real (a door, windows). Real interiors are NOT needed: openings show a dark
room (a recessed dark plane 0.4 m behind, never see-through). Doors, steps, sills, corbels, beams, tiles and slates as
geometry where they catch light; bevelled edges; leaning timbers, a slightly sagging ridge, uneven eaves; nothing floating,
no z-fighting.

ONE shared material shelf for all six (this is a kit: the same granite / oak / plaster / tile / slate / rubble / iron /
glass materials, at most 10 materials in total): photographic CC0 Poly Haven textures (dl.polyhaven.org, 1k or 2k jpg;
list every id in NOTES.md) with node detail (moss on roofs, grime at the wall foot, rain streaks, edge wear), baked with
Cycles to TILEABLE image textures (base colour, normal, ORM), max 1024 px (ORM 512), world-scale UVs (about 1 texture repeat
per 2 m) so every house shares them. Per-house variety and ageing goes in vertex colours (COLOR_0, multiplied with base
colour: AO in corners and under eaves, moss and soot patches, plaster tint) so no house needs its own images. Each house
also gets a second plaster or tile tint via vertex colour so the six do not look like one paint pot.
Budget: 30k to 70k triangles per house, whole kit <= 350k, GLB <= 25 MB.

Export: medieval-hero-houses.glb (binary, Y up, metres, transforms applied, no cameras/lights): six root nodes named
exactly as above, laid out side by side 14 m apart along X in the file (their positions are ignored by code; each root's
children are in the house's own frame relative to the root). Under each root: the meshes, plus empties Entrance (on the
ground 0.8 m in front of the main door) and Door (centre of the main door bottom).
Work INCREMENTALLY: build_kit.py builds all houses done so far and exports; re-export after each finished house, so a
usable partial kit always exists. Deliver here: medieval-hero-houses.glb; build_kit.py (one clean run from an empty scene
makes the GLB); lineup.png (1920x1080 Cycles, the six in a row as a street, soft daylight); final_<n>.png (each house 3/4
front); clay_lineup.png; nodes.json (per root: bounding box in its own frame, triangle count); NOTES.md (6 lines).
Hard stop at 01:46 CET: by then the GLB holds every house you finished. Quality over count: 4 excellent houses beat 6
cheap ones. Order: 1, 2, 3, 5, 4, 6.

**Verdict: REVISE.** The rev0 comparison is BLOCKED: `rev0/final_1.png` doesn't exist (Read returned "File does not exist"), and I'm limited to Read, so I couldn't list the folder. I saw the reference and the current `final_1`, `final_2` and `final_5` (1920×1080 coordinates below).

**Findings, by priority**

1. **Side-wall plaster looks like a flat sheet of paper.**
   - Evidence: `final_1` wall at x1090–1370, y400–950, `final_2` at x1050–1350, y450–950, and `final_5` at x1100–1440, y300–870 are all near-uniform fill. Stone shows only at the torn silhouette edges and bottom strip (`final_5` x1110–1330, y790–880).
   - `final_5` gable (x1120–1330, y230–400) has blocky 20–40 px squares, a texture artifact.
   - I agree with moving the losses into visible panel gaps, but that alone won't fix a blank 300×550 px wall.
   - Fix: scatter patches across the open wall field, with a stepped recessed edge. Add a damp gradient and mottling.
   - Accept:
     - Each large wall has at least 5 separate loss patches, each covering 2–8% of the wall.
     - At least 40% of the patches sit away from borders and trims.
     - Stone shows 1–3 cm below the plaster face.
     - The bottom 25% of the wall is at least 12% darker than the top.
     - Plaster luminance standard deviation is 0.05 or more.
     - No visible texel blocks larger than 6 px at 1080p.

2. **There is no weathering story: no rain streaks, soot or damp.**
   - Evidence: nothing runs down from the sills, sign bracket, eaves or the `final_2` chimney (x1100–1200, y10–130). The only "damp" is a green skirt (`final_1` x650–1390, y985–1030).
   - Fix: add vertical streak decals below every projecting element, soot above openings and around the chimney, and a damp band at the base.
   - Accept: 8 or more visible streaks per facade, 80–300 px long, 8–15% darker than the surrounding wall. Soot is visible on every chimney and above at least 2 openings.

3. **The roofs read as saturated and cloth-warped, not old and grey-oak.**
   - Evidence: `final_2` and `final_5` roofs are bright terracotta, and `final_1` is saturated green. The ridge wave (`final_1` x1000–1390, y340–390) looks like a mesh warp, with tiles crossing each other.
   - The holes (`final_1` x1045, y340; `final_2` x90, y260; `final_5` x1050, y350) are pure black rectangles.
   - Fix: desaturate the tile body and use moss in patches. Make the sag smooth and carry it into the eave and gutter line. Show battens or underlay through the holes.
   - Accept:
     - Mean tile saturation is 0.35 or less.
     - Moss covers no more than 25% of the roof.
     - Tile courses stay parallel.
     - Holes show a brown or dark value above RGB 25, not black.
     - The eave deflects at least 1.5% of its span, following the ridge.

4. **Dressing, glass and sky are uneven across the three houses.**
   - **`final_1`:** no lantern, sign, goods, gutter, downpipe or chimney. Plants are one tiny box (x810–890, y785–805).
   - **`final_2` and `final_5`:** these have a sign, lantern, goods, a flower box, a downpipe and a plank. The shop interiors are flat black voids (`final_2` x790–1000, y850–960; `final_5` x640–850, y690–870).
   - **Glass:** it reads cool blue-grey with a brown lower half (`final_1` x680–1010, y440–490), which looks like dirt, not warmth.
   - **Sky:** the background is a plain grey gradient.
   - Fix: give each house at least one sign or lantern, 2 goods or plant items, and a gutter with a downpipe. Give the voids a back wall, shelves and a warm interior. Warm about a third of the panes, and add a sky gradient.
   - Accept:
     - At least 30% of panes have a warm tint, with hue 25–40° and value 20–35% above the cool panes.
     - No shop interior is darker than RGB 15.
     - The background shows a visible top-to-horizon gradient.

5. **Style and material realism versus Breton.**
   - **Breton reference:** it sells age through a rubble texture across the whole wall, crisp granite quoins, bevelled trims, slate-blue roof and clean metal gutters.
   - **These models:** they are tinted flat colour. The ochre plaster (`final_2`) is cartoon-saturated, and trims have little bevel or contact shadow. Grey oak is the one thing that works.
   - Candidly, the timber-frame typology is fine, but the material finish is below the reference.
   - Fix: lower plaster saturation, add a bevel and contact darkening at trim and wall junctions, and raise texture density.
   - Accept:
     - Plaster mean saturation is 0.25 or less.
     - Texture density is 512 px/m or more.
     - All trim edges show a highlight on 1080p renders.
     - Contact darkening of at least 10% appears at wall and trim junctions.

**Regressions versus rev0:** unverifiable. Please give me a path that exists to check.

codex
The final GLB is 23.72 MB with 300,419 triangles across ten shared materials. All six houses are below 70k triangles. Structural checks pass, and the glTF validator reports zero errors; its warnings concern tangents generated by the loader.

**Verdict: REVISE.** Material and dressing are in good shape. Plaster walls, runoff and roof color are not.

Limits: I judged by eye from the eight images only. I did not see final_3 or final_4, the GLB, or any pixel statistics. Coordinates are from the 1920×1080 images.

| # | Status | One line |
|---|---|---|
| 1 | Partly resolved | Losses moved and side losses added, but the walls still read as blank sheets |
| 2 | Remaining | Runoff and soot are not readable at final scale, and the green plinth is new |
| 3 | Partly resolved, one regression | Cracking is better; house 1 roof is now greener than rev0 |
| 4 | Resolved | Counts, dressing, glass and the dark voids all match the brief |
| 5 | Partly resolved | Grey oak works; plaster finish is still flat |

**1. Side-wall plaster: partly resolved**
- **Better:** losses now sit on the side walls, not only on the silhouette. Examples are the teardrop at final_1 x1150–1230, y680–800 and final_5 x1160–1210, y690–810. The returns and the torn base are visible.
- **Remaining:** the open wall fields are still flat. These are final_1 x1075–1380, y400–940, final_2 x1050–1370, y430–930, and final_6 x1070–1420, y500–860.
  - The only structure is faint vertical seam banding, which reads like paper.
  - The isolated loss is the same teardrop on every house.
  - Its edge is a hard cutout with no recessed lip.
- **Fix (required):** give each isolated loss a stepped recessed lip and a shadow side. Give the plaster face a mottled stain and a darker lower gradient. Reduce the vertical seam banding.
- **Suggestion:** vary the loss outlines between houses.
- **Accept:** the 2–4 loss count per house is unchanged. At 1080p, no loss edge reads as a flat cutout, and the large wall fields no longer read as uniform fill.

**2. Weathering and runoff: remaining**
- I could not see causal streaks at final scale.
  - Nothing reads under the sign brackets (final_2 x700–760, y790–830; final_6 x950–1000, y680–740).
  - Nothing reads under the window sills (final_5 x870–990, y650–700).
  - There is no soot at the chimneys (final_2 x1100–1200, y10–130; final_6 x740–830, y90–300).
- The plinth, steps and base now read as mint-green paint, for example lineup x95–185, y770–800 and final_1 x650–1390, y985–1030. rev0 had grey steps, so this is a new artifact.
- **Fix (required):** make the downpipe and gutter runoff visible at 1080p, as a darker vertical value shift below each outlet and under the two sign brackets. Desaturate the green base to a grey-brown damp.
- **Accept:** the downpipe and gutter counts stay at two each. A streak from a gutter or sign bracket is identifiable in final_2, final_5 and final_6, and the plinth does not read as green paint.
- **Suggestion:** a soot tint on the two or three chimneys.

**3. Roofs: partly resolved, one regression**
- **Better:** the cracking is no longer pure black slabs in the lineup. The final_5 roof is browner and calmer than in pass 1.
- **Regression:** the house 1 roof (final_1 and lineup x150–520, y50–400) is now green and dominant. rev0 and the Breton reference are slate-blue.
- **Remaining:**
  - The ridge sag still reads as a mesh warp. See the lineup middle roof x700–1110, y300–360, and final_5 x1050–1280, y180–260.
  - The holes in final_5 (x1000–1020, y305–315; x1255–1285, y355–370) are still near-black.
  - There is a pale sliver at final_5 x1185–1255, y488–497, which looks like a roof/wall gap artifact.
- **Fix (required):** return the house 1 roof to slate-blue with moss as patches only. Make the holes show a visible brown underlay. Close or explain the pale sliver at the final_5 eave.
- **Suggestion:** soften the sag so tile courses stay parallel.
- **Accept:** the house 1 roof reads slate-blue first and green second. No roof hole reads as a pure black rectangle. The final_5 eave has no light gap.

**4. Dressing, glass, voids and sky: resolved**
- The counts match the brief, and the dressing sits where it should.
  - Two window boxes are visible (lineup x210–275, y635–665 and x1100–1150, y700–730).
  - Two lanterns are visible (final_2 x635–665, y815–860 and final_6 x850–885, y740–790).
  - Downpipes are present.
- The glass is quieter and cool, and no longer looks dirty.
- The dark recessed shop voids and the plain grey background are the brief's intent, so I do not count them as defects.
- **Acceptance if you touch it again:** do not add more dressing items. The counts stay as they are.

**5. Finish against the Breton reference: partly resolved**
- **Better:** the grey oak is cohesive across houses and is the strongest part of the set.
- **Remaining:**
  - The plaster has no bevel, contact darkening or grain.
  - The trims are flat grey with little highlight.
  - The final_2 and final_6 plaster is still a saturated mustard-ochre, while final_5 and final_1 are paler. The set is uneven.
  - The reference's crisp finish is absent. The different typology is intentional, so I judge finish only.
- **Fix (suggestion):** pull the final_2 and final_6 ochre toward the final_5 value. Add a subtle edge highlight and contact shadow where trim meets plaster.
- **Accept:** plaster saturation is consistent across the three houses. Trim meets wall with visible contact shading at 1080p.

**Required to move to PASS:** items 1 and 2, and the house 1 roof regression and the black holes in item 3. Everything else is a suggestion.

Revision 1 started 00:19 CEST, 9 October 2026; hard delivery checkpoint 01:27 CEST (Europe/Paris, operator's CET label).
Preserve rev0/; modify builder and atomically replace GLB after each finished house. Six exact named roots and frames, 30–70k triangles per house, <=350k kit, <=25,000,000 bytes, <=10 shared materials. No unique house textures.
New geometry/vertex-colour wear and street life per PROMPT-r1.txt; original PROMPT.txt still applies. Camera/lighting stay matched to rev0. Inspect reimported GLB Cycles lineup, individual fronts, rear views and clay; measure exported Three.js runtime separately.
Bounded correction passes: first complete build, visual correction, final validation. Preserve full build log, GLB contract audit, runtime captures and six-line NOTES.md.
