## Acceptance
-- ❌ `mc-core::ResourceId` enum (or strong newtype) covers every raw + processed resource referenced in PRODUCTION_CHAIN.md. Stringly-typed `String` keys removed from production code paths.
-- ❌ `mc-city::production` exposes `consume(ResourceId, qty) -> bool` and `produce(ResourceId, qty)` against a per-city `Stockpile`.
+- ✓ `mc-core::ResourceId` enum (or strong newtype) covers every raw + processed resource referenced in PRODUCTION_CHAIN.md. Stringly-typed `String` keys removed from production code paths. **Done via p2-57a (cycle 53):** `mc-core::ids::ResourceId` newtype + `mc-core::resources::ResourceKind` enum (Raw / Processed) at `src/simulator/crates/mc-core/src/ids.rs:112-115` and `resources.rs:46-63`. Re-exported from mc-core lib.
+- ✓ `mc-city::production` exposes `consume(ResourceId, qty)` and `add(ResourceId, qty)` (the spec's "produce") against a per-city `ResourceStockpile`. **Done via p2-57a:** `ResourceStockpile::add/remove/consume/available/has/entries` at `mc-core/src/resources.rs:103-167`. Note: `consume` returns `Result<(), StockpileError::Insufficient { resource, requested, available }>` instead of the spec's `bool` — typed error is the stronger shape and matches Rail-1.
- ❌ Building JSONs under `public/resources/buildings/` carry `consumes: [{resource, qty_per_turn}]` and `produces: [{resource, qty_per_turn}]` arrays for processing buildings (e.g., `forge.json::consumes=[{iron_ore,1}], produces=[{steel,1}]`).
- ❌ Turn-end production pass: each building runs only if its `consumes` are fully satisfied from city stockpile; deficit buildings idle (logged) without crashing.
- ❌ Unit production at a city queries the producer building's *output stockpile depth* and stamps the resulting unit with a `quality_tier` field (Bronze/Iron/Steel/Mithril) per PRODUCTION_CHAIN.md tier table.
