# SHiRE Academy Stage 3C.3.1 — Learning Bridge + Gothic Dice Tower

This package upgrades the live Stage 3C.2 Speed Core without returning to npm or Base44.

## What changes

- Checks high-level design intent before component words such as `tray`.
- Prevents a dice tower, skull, articulated model, or unknown design from silently becoming a simpler starter object.
- Adds a SHiREVault-backed Unsupported Request Learning Bridge.
- Adds a validated `gothic_dice_tower` Fast Builder family.
- Parses named dimensions, ramp count, ramp angles, minimum dice passage, base, collection tray and Gothic feature intent.
- Adds eight deterministic dice-tower practice exercises to the autonomous curriculum.
- Expands autonomous practice from 48 to 72 evidence runs while preserving existing progress.
- Keeps the warm local CadQuery Unix-socket engine and direct STEP/STL generation.

## Built-in evidence

The installer must pass three real Gothic dice-tower parameter variants. Each creates and validates STEP and STL files on SHiREVault before the capability pack is marked `validated_draft_template`.

## Permanent boundaries

- Existing 371-skill state remains read-only.
- No counted attempt is consumed.
- No certification or Forge permission changes.
- No arbitrary prompt/code execution.
- No external network research.
- No public port.
- All outputs remain non-load-bearing drafts requiring 3D-view, slicer and physical dice-flow inspection.


## Verification-path correction

The persistent CadQuery worker remains restricted to `/SHiREVault/SHiREAcademy/FastBuilder`. Capability proofs are now built and validated in that allowlisted system-test tree, then copied into the Learning Bridge capability-evidence tree. No filesystem allowlist was widened.
