 ## Project Overview
 
-The Nexus is Timmy's canonical 3D/home-world repo.
-Its intended role is:
-- local-first training ground for Timmy
-- wizardly visualization surface for the system
+The Nexus is a Three.js environment — Timmy's sovereign home in 3D space. It serves as the central hub for all portals to other worlds. Stack: vanilla JS ES modules, Three.js 0.183, no bundler.
 
-## Current Repo Truth
+## Architecture
 
-Do not describe this repo as a live browser app on `main`.
+```
+index.html    # Entry point: HUD, chat panel, loading screen, live-reload script
+style.css     # Design system: dark space theme, holographic panels
+app.js        # Three.js scene, shaders, controls, game loop (~all logic)
+```
 
-Current `main` does not ship the old root frontend files:
-- `index.html`
-- `app.js`
-- `style.css`
-- `package.json`
+No build step. Served as static files. Import maps in `index.html` handle Three.js resolution.
 
-A clean checkout of current `main` serves a directory listing if you static-serve the repo root.
-That is world-state truth.
+## Conventions
 
-The live browser shell people remember exists in legacy form at:
-- `/Users/apayne/the-matrix`
+- **ES modules only** — no CommonJS, no bundler
+- **Single-file app** — logic lives in `app.js`; don't split without good reason
+- **Color palette** — defined in `NEXUS.colors` at top of `app.js`
+- **Conventional commits**: `feat:`, `fix:`, `refactor:`, `test:`, `chore:`
+- **Branch naming**: `claude/issue-{N}` (e.g. `claude/issue-5`)
+- **One PR at a time** — wait for merge-bot before opening the next
 
-That legacy app is source material for migration, not a second canonical repo.
+## Validation (merge-bot checks)
 
-Timmy_Foundation/the-nexus is the only canonical 3D repo.
+The `nexus-merge-bot.sh` validates PRs before auto-merge:
 
-See:
-- `LEGACY_MATRIX_AUDIT.md`
-- issues `#684`, `#685`, `#686`, `#687`
+1. HTML validation — `index.html` must be valid HTML
+2. JS syntax — `node --check app.js` must pass
+3. JSON validation — any `.json` files must parse
+4. File size budget — JS files must be < 500 KB
 
-## Architecture (current main)
+**Always run `node --check app.js` before committing.**
 
-Current repo contents are centered on:
-- `nexus/` — Python cognition / heartbeat components
-- `server.py` — local websocket bridge
-- `portals.json`, `vision.json` — data/config artifacts
-- deployment/docs files
+## Sequential Build Order — Nexus v1
 
-Do not tell contributors to run Vite or edit a nonexistent root frontend on current `main`.
-If browser/UI work is being restored, it must happen through the migration backlog and land back here.
+Issues must be addressed one at a time. Only one PR open at a time.

-1. One canonical 3D repo only: `Timmy_Foundation/the-nexus`
-2. No parallel evolution of `/Users/apayne/the-matrix` as if it were the product
-3. Rescue useful legacy Matrix work by auditing and migrating it here
-4. Telemetry and durable truth flow through Hermes harness
-5. OpenClaw remains a sidecar, not the governing authority
-6. Before claiming visual validation, prove the app being viewed actually comes from current `the-nexus`
+## PR Rules
 
-## Validation Rule
+- Base every PR on latest `main`
+- Squash merge only
+- **Do NOT merge manually** — merge-bot handles merges
+- If merge-bot comments "CONFLICT": rebase onto `main` and force-push your branch
+- Include `Fixes #N` or `Refs #N` in commit message
 
-If you are asked to visually validate Nexus:
-- prove the tested app comes from a clean checkout/worktree of `Timmy_Foundation/the-nexus`
-- if current `main` only serves a directory listing or otherwise lacks the browser world, stop calling it visually validated
-- pivot to migration audit and issue triage instead of pretending the world still exists
+## Running Locally
 
-## Migration Priorities
+```bash
+npx serve . -l 3000
+# open http://localhost:3000
+```
 
-1. `#684` — docs truth
-2. `#685` — legacy Matrix preservation audit
-3. `#686` — browser smoke / visual validation rebuild
-4. `#687` — restore wizardly local-first visual shell
-5. then continue portal/gameplay work (`#672`, `#673`, `#674`, `#675`)
+## Gitea API
 
-## Legacy Matrix rescue targets
-
-The old Matrix contains real quality work worth auditing:
-- visitor movement and embodiment
-- agent presence / bark / chat systems
-- transcript logging
-- ambient world systems
-- satflow / economy visualization
-- browser smoke tests and production build discipline
-
-Preserve the good work.
-Do not preserve stale assumptions or fake architecture.
