ESIR-first repo-local development surface for Exotic Space Industries: Remembrance. Use when Codex should work faster inside this workspace by relying on checked-in manifests, the ESIR wrapper command, Factorio QC delegation, Mod Portal scouting, save catalog resolution, Lua/runtime/prototype helper routing, Meshy/Blender asset pipeline routing, Factorio asset export, item icon prep, recipe icon style audits, art/browser session handoff, cache diffing, packaging, or ESIR-specific runtime/prototype maps.
Use when Codex should create, inspect, or render Blender procedural animations for non-human assets, ESIR machines, crystals, gates, orbitals, props, Meshy GLBs, animation spritesheets, or Factorio-ready transparent frame sheets.
Use when Codex should orchestrate a full ESIR asset pipeline from Meshy prompts or existing models through Blender static/procedural rendering, Factorio-style shadows, staged Factorio export, previews, QA, manifests, and reproducible asset dossiers.
Use when Codex should stage Meshy/Blender spritesheets, animated sheets, shadow sheets, or source icon art as Factorio/ESIR-ready asset drafts with previews, manifests, and Lua prototype snippets without wiring them into the mod.
Use when ESIR item art needs to be turned into a transparent Factorio item icon strip, especially when source art has a baked light checkerboard or white background and must end up as a `128/64/32` mipmapped item icon under `exotic-space-industries-remembrance/graphics/items/`.
Prefer the shared `ei_lib` helper surface in `exotic-space-industries-remembrance/lib/lib.lua` before creating new Lua local functions. Use when Codex edits ESIR runtime, data-stage, prototype, migration, or support Lua files and might add utility helpers, table or string helpers, recipe or technology mutation helpers, notification helpers, color or formatting helpers, wrappers around `data.raw`, prototype `custom_tooltip_fields`, or runtime `LuaEntity.custom_status` combat readouts such as DPS/status rows for weapons, turrets, or vehicles. For runtime queue, delayed-bucket, telemetry-gate, counter, or status-snapshot plumbing, prefer `exotic-space-industries-remembrance/lib/runtime-scheduler.lua` instead. Inspect `ei_lib` first when the helper is general utility; if it almost fits, extend or harden the shared function instead of inventing a one-off local helper.
Use when Codex should render or wire ESIR Factorio train and rolling-stock body sprites, especially elevated-rail sloped train sprites, rolling_stock_template.blend, susanne_0.0.1.zip precedent, Spritter spritesheet packing, normal/sloped frame contracts, or prototype RotatedSprite metadata for locomotives, cargo wagons, fluid wagons, or train bodies.
Use when Codex needs to import, audit, replace, or choose Factorio's bundled `data/core/lualib` helpers in ESIR or other Factorio mod Lua, especially `require("__core__.lualib.meld")`, `util`, `mod-gui`, `resource-autoplace`, `collision-mask-util`, `math2d`, `math3d`, `event_handler`, `sound-util`, `circuit-connector-sprites`, `story`, `silo-script`, `space-finish-script`, `production-score`, or `kill-score`. Use before reimplementing helper behavior that Factorio core already ships, before changing existing core lualib imports, and when deciding between core lualib helpers, ESIR `ei_lib`, direct prototype mutation, or local Lua helpers.
