# SHiRE Academy Stage 3C.1 — Autonomous Gothic Practice

This package advances the proven Stage 3B Fast Object Builder without activating the old counted-certification worker.

## Builder improvements

- Adds a project/file-name field with a safe cross-platform filename stem.
- Lets Ray choose STEP, STL, or both before generation.
- Uses the chosen name for the real downloaded files and SHiREVault artifacts.
- Adds Collapse and Close controls for safe plans.
- Adds Close/Show controls for completed job panels without deleting evidence.
- Keeps the fast local 3D STL viewer and direct downloads.

## Autonomous practice foundation

- Installs `shire-academy-autonomous-practice.service` as a resource-limited background worker.
- Starts an allowlisted `Gothic Geometry Foundations` curriculum immediately after installation.
- Runs eight deterministic CadQuery exercises across three parameter variants:
  pointed arches, lancets, quatrefoils, trefoils, rose windows, ribs, tracery, and an organiser facade.
- Stores real STEP/STL and validation evidence at:
  `/SHiREVault/SHiREAcademy/AutonomousPractice/GothicFoundations/`
- Runs one exercise every 120 seconds and pauses after 24 successful evidence runs for Ray's review.
- Provides local UI status, Pause, Resume and Run One controls.

## Permanent safety boundary

- Existing 371-skill practice state remains read-only.
- No counted attempts are consumed.
- No certification file is changed.
- No Forge permission is changed or unlocked.
- No arbitrary prompts, user code, shell commands, external research, publishing, spending, credentials or public ports.
- Three consecutive failures or any protected-state hash change causes a safety stop.
- Organic skull mastery is not claimed; the first autonomous curriculum builds validated Gothic architectural foundations.
