Build the linux .so/wasm once on a worker and let sim/test/AI runners fetch the
prebuilt artifact (keyed by git sha) instead of recompiling — N workers share
one build. Adds the magicciv-artifacts DO Space, rclone in the golden image, and:
- dist:publish build + upload builds/<sha>/{.so,wasm}
- dist:fetch download the prebuilt .so for HEAD's sha
- dist:sync git pull -> fetch prebuilt if published, else build
- dist:models share RL .onnx via the Space (push/pull/ls)
Complements sccache (compile cache) by caching final outputs. Creds via
RCLONE_S3_* env over ssh, never on worker disk/argv; degrades to build-on-worker
when creds/cache absent.
Also hardens the dispatch layer (pre-existing, affected test/build/render too):
- pass -i ~/.ssh/id_mc_fleet on dispatch ssh (don't rely on agent-loaded key)
- guard _dist_first_host against an empty / "fleet down" inventory
- drop ssh -n on heredoc-stdin verbs (it redirected stdin from /dev/null)
Proven end-to-end on DO: publish built a 43.9MB .so + wasm; dist:sync fetched it
in 2.8s (no rebuild).

Incremental rebuilds accumulate snapshots (~$0.40/mo each). dist:prune keeps
the newest N (default 2: current + one rollback); dist:image reminds you to run it.

Packer base image is now a var; ./run dist:image builds FROM the newest
mc-golden snapshot by default, so the idempotent provision.sh only redoes changed
work (~3-8 min vs ~20 cold). --cold rebuilds from stock Ubuntu to reset layer
cruft. Made the clone step idempotent (clone-or-fetch) so it works on a
pre-provisioned base. Directly addresses 'avoid unnecessary rebuilds'.

Golden image now installs the software-render stack (weston, libgl1-mesa-dri
llvmpipe, mesa-vulkan-drivers, vulkan-tools) so any worker renders proof scenes
via gl_compatibility/opengl3 with no GPU. New ./run dist:render <scene> <out.png>
wraps tools/capture-proof.sh against a worker (replaces the apricot SCREENSHOT_HOST).

Offload heavy compute from plum (M2 Air) to on-demand DO workers:
- dist:test — cargo test --workspace (nextest) on a worker (the main DX win)
- dist:build — cargo build + WASM on a worker; rsync the platform-independent
WASM back (native .so is linux-only, stays on the worker)
- dist:sync — git pull <ref> + rebuild gdext on live workers (no image rebuild)
- forge:down/up — snapshot+destroy / restore-from-snapshot (DO bills powered-off
droplets; only destroy stops it). ~$6/mo -> ~$0.30/mo idle; refreshes the
forge IP in ~/.vault/mc_forge_creds on restore.

Ephemeral CPU Droplet fleet that horizontally scales the iteration loop:
- infra/terraform/test-fleet: cattle Droplets from a golden image (auto-discovered
by name via digitalocean_images), grouped under the mc:dev DO project, with a
mocked-provider test suite (no token/spend).
- infra/packer: golden-image builder reusing scripts/dev-setup/linux.sh.
- scripts/run/dist.sh: ./run dist:{check,up,sim,train,down} — shard sim/test
batches across workers via autoplay-batch AUTOPLAY_HOST+SEED_OFFSET.
GPU intentionally absent (workload is CPU-bound per docs/ai-production.md).

Verified file:line: the live GDScript events modules have NO era-based max_tier
cap (0 hits) — headless flat max_tier=10 is correct parity; an era cap would
invent a rule the game lacks (gold-plating, dropped). And natural events already
fire + apply terrain effects headless; only the fired list surfacing to
TurnResult is missing (processor.rs:1117 `let _fired =`), an observability nicety
not a system gap. Confirms the headless natural-events system is functionally
complete; narrows Gap-2's real remainder.

The live GDScript turn emitted `unit_healed` inline; the headless healing
phase recovered HP silently. The healing phase runs in the end-of-turn
`fn(&mut GameState)` registry (no event sink), so follow the FloraSuccession
buffer pattern: stash `(player, unit_id, applied_amount, col, row)` into a new
transient `GameState.pending_heal_events`, drain it in `step()` into
`TurnEvent::UnitHealed`. The buffered amount is the CLAMPED delta actually
applied (not the nominal heal rate). No wire surface — dispatch drops it; the
live UI consumes it via the kind-tagged `event_to_dict` dict.
Verified headless: mc-replay 19/0 (unit_healed_serde), mc-turn 289/0
(healing_buffers_unit_heal_event_with_applied_amount +
healing_buffers_clamped_amount_near_full_hp + event_collector_wiring).

Add tools/check-no-gdscript-sim-logic.py and wire it as verify step 18 (TOTAL
20→21). Fails if presentation GDScript (src/game/engine/src/**/*.gd) re-introduces
catalog yield aggregation (`yield_production += …`) or hand-built spec dicts
(`"yield_production": …`) — the exact drift class just moved to Rust. Verified to
flag the pre-7e2baa25d aggregation and pass clean on the current tree. Logic
belongs in the mc-* crates, reached via the GDExtension bridge (Rail 1).

Game opening becomes a moddable JSON script driven by mc_worldsim::StartScriptRunner
and exposed to Godot via GdStartScript. Start scripts + dwarf tribe/wanderer units
live in public/resources/start_scripts; START_SCRIPTS.md documents the contract.
Adds tools/validate-start-scripts.py + wires it into CI (stage 3b) and verify.sh
(step 0b). Marks p3-14 done and regenerates the objectives dashboard.

Add tools/check-ui-color-sources.py: fails if a hardcoded numeric Color()/Color8()
is applied to a widget in a scene (add_theme_*_override / StyleBox *_color).
Allows computed Color(accent.r,…), transparent, named constants, and var-init
fallbacks; excludes scenes/tests + the 3 precursor deletion files. Passes clean
on live scenes (exit 0). Wired into ./run verify as step 17 so a hardcoded
colour can't creep back in.
Capstone for the override→inheritance / single-colour-system work: colours in
live scenes now provably come from the design-token source.

- render_client.ts: TCP client that spawns the rendered game via
render-driver-server.sh, then sends screenshot / open_screen / ping correlated
by id (distinct from the headless stdin HarnessClient).
- scripts/render-driver-server.sh: boots the REAL game (MC_AUTO_START +
MC_MCP_RENDER, gl_compatibility, not --headless) so the driver captures real
frames; client connects on MC_MCP_PORT.
- index.ts: magic_civ_screenshot + magic_civ_open_screen tools, render-client
holder + cleanup.
Verified end-to-end through the BUILT TypeScript (no Claude restart needed):
RenderClient -> game -> TCP ping {ok}, screenshot -> a real 3420x1923 PNG of the
live world map. dist/ is gitignored (built locally per .mcp.json); the tools
surface in a Claude session after the next restart.
