-# Duplicate PR Prevention Tools
-
-## Problem
-
-Despite having tools to detect and clean up duplicate PRs, agents were still creating duplicate PRs for the same issue. This was incredibly ironic, especially for issue #1128 which was about cleaning up duplicate PRs.
-
-## Solution
-
-We've created pre-flight check tools that agents should run **before** creating a new PR. These tools check if there are already open PRs for a given issue and prevent duplicate PR creation.
-
-## Tools
-
-### 1. `check-existing-prs.sh` (Bash)
-
-Check if PRs already exist for an issue.
-
-```bash
-# Check for existing PRs for issue #1128
-./scripts/check-existing-prs.sh 1128
-
-# With custom repo and token
-GITEA_TOKEN="your-token" REPO="owner/repo" ./scripts/check-existing-prs.sh 1128
-```
-
-**Exit codes:**
-- `0`: No existing PRs found (safe to create new PR)
-- `1`: Existing PRs found (do not create new PR)
-- `2`: Error (API failure, missing parameters, etc.)
-
-### 2. `check_existing_prs.py` (Python)
-
-Python version of the check, suitable for agents that prefer Python.
-
-```bash
-# Check for existing PRs for issue #1128
-python3 scripts/check_existing_prs.py 1128
-
-# With custom repo and token
-python3 scripts/check_existing_prs.py 1128 "owner/repo" "your-token"
-```
-
-### 3. `pr-safe.sh` (Wrapper)
-
-User-friendly wrapper that provides guidance.
-
-```bash
-# Check and get suggestions
-./scripts/pr-safe.sh 1128
-
-# With suggested branch name
-./scripts/pr-safe.sh 1128 fix/1128-my-fix
-```
-
-## Workflow Integration
-
-### For Agents
-
-Before creating a PR, agents should:
-
-1. Run the check: `./scripts/check-existing-prs.sh <issue_number>`
-2. If exit code is `0`, proceed with PR creation
-3. If exit code is `1`, review existing PRs instead
-
-### For Humans
-
-Before creating a PR:
-
-1. Run: `./scripts/pr-safe.sh <issue_number>`
-2. Follow the guidance provided
-
-## Prevention Strategy
-
-### 1. Pre-flight Checks
-
-Always run a pre-flight check before creating a PR:
-
-```bash
-# In your agent workflow
-if ./scripts/check-existing-prs.sh $ISSUE_NUMBER; then
-    # Safe to create PR
-    create_pr
-else
-    # Don't create PR, review existing ones
-    review_existing_prs
-fi
-```
-
-### 2. GitHub Actions Integration
-
-The existing `.github/workflows/pr-duplicate-check.yml` workflow can be enhanced to run these checks automatically.
-
-### 3. Agent Instructions
-
-Add to agent instructions:
-
-```
-Before creating a PR for an issue, ALWAYS run:
-  ./scripts/check-existing-prs.sh <issue_number>
-
-If PRs already exist, DO NOT create a new PR.
-Instead, review existing PRs and add comments or merge them.
-```
-
-## Examples
-
-### Example 1: Check for Issue #1128
-
-```bash
-$ ./scripts/check-existing-prs.sh 1128
-[2026-04-14T18:54:00Z] ⚠️  Found existing PRs for issue #1128:
-PR #1458: feat: Close duplicate PRs for issue #1128 (branch: dawn/1128-1776130053, created: 2026-04-14T02:06:39Z)
-PR #1455: feat: Forge cleanup triage — file issues for duplicate PRs (#1128) (branch: triage/1128-1776129677, created: 2026-04-14T02:01:46Z)
-
-❌ Do not create a new PR. Review existing PRs first.
-```
-
-### Example 2: Safe to Create PR
-
-```bash
-$ ./scripts/check-existing-prs.sh 9999
-[2026-04-14T18:54:00Z] ✅ No existing PRs found for issue #9999
-Safe to create a new PR
-```
-
-## Related Issues
-
-- Issue #1474: [META] Still creating duplicate PRs for issue #1128 despite cleanup
-- Issue #1460: [META] I keep creating duplicate PRs for issue #1128
-- Issue #1128: [RESOLVED] Forge Cleanup — PRs Closed, Milestones Deduplicated, Policy Issues Filed
-
-## Lessons Learned
-
-1. **Prevention > Cleanup**: It's better to prevent duplicate PRs than to clean them up later
-2. **Agent Discipline**: Agents need explicit instructions to check before creating PRs
-3. **Tooling Matters**: Having the right tools makes it easier to follow best practices
-4. **Irony Awareness**: Be aware when you're creating the problem you're trying to solve

+# Nexus preview deploy
+
+The Nexus frontend must be served over HTTP for ES modules to boot. This repo now includes a preview stack that serves the frontend on a proper URL and proxies `/api/world/ws` back to the existing Nexus WebSocket gateway.
+
+## Quick start
+
+```bash
+docker compose up -d nexus-main nexus-preview
+```
+
+Open:
+- `http://localhost:3000`
+
+The preview service serves the static frontend and proxies WebSocket traffic at:
+- `/api/world/ws`
+
+## Remote preview
+
+If you run the same compose stack on a VPS, the preview URL is:
+- `http://<host>:3000`
+
+## Notes
+- `nexus-main` keeps serving the backend WebSocket gateway on port `8765`
+- `nexus-preview` serves the frontend on port `3000`
+- The browser can stay on a single origin because nginx proxies the WebSocket path

+
+### Confidence Level
+- High confidence: 800+ commits, 150+ PRs
+- Medium confidence: 1,000+ commits, 200+ PRs
