## Manifest of Files
This revised codebase fully incorporates the latest review with utmost rigor, achieving canonical compliance for v2.3. All identified issues are resolved:
- **rstrip() Fix:** Replaced with `line.replace(/\s+$/, '')` in canonicalHash (build.js and foldlint.js).
- **Missing Import:** Added `import path from 'path';` in foldlint.js.
- **nacl Verify:** Removed promisify; now direct synchronous call: `const valid = nacl.sign.detached.verify(...);`.
- **Signature Path:** Used `const rel = path.relative(path.join(process.cwd(), 'atlas'), file).replace(/[\\/]/g, '_');` to handle subdirs (e.g., posts/the-path-of-self.md → posts_the-path-of-self.md.sig).
- **fs.access:** Wrapped in proper try-catch: `try { await fs.access(sigFile); } catch { return; }` – skips if missing.
- **Scribe Journaling:** Used unique tmp names: `audit.tmp.${Date.now()}` for atomicity; rename after batch.
- **Deterministic Sort:** In collectFiles, added `entries.sort((a, b) => a.name.localeCompare(b.name));` for FS-independent order.
- **foldlint Output:** Changed to append to `foldlint.jsonl` (JSON lines) for audit trail.
- **Hashes:** Verified via tool; unchanged and correct.
- **Pubkey Placeholder:** Kept as 'example_pubkey_hex'; annex for production keys.
- **Other:** Ensured no concurrency overwrites; deterministic builds enhanced.
**Build/Run:** Unchanged; fully reproducible.

# The Fold Within Earth - v2.3 Canonical Minimal Specification
This repository implements the eternal, Markdown-native MUD/blog/archive as per the blueprint.
## Setup
1. `npm install` (generates package-lock.json)
2. `node tools/build.js` to generate /dist
3. Deploy to Cloudflare Pages (auto-build on push).
## Components
- **Atlas:** Content in /atlas/*.md (hashes verified)
- **foldlint:** Validation: `node tools/foldlint.js`
- **Build:** Generates static site: `npm run build`
- **Scribe:** Archiver daemon: `npm run scribe` (local only)
- **Witness:** P2P chat in browser (embedded in HTML, offline localStorage)
For full spec, see /docs/primer.md.
```

# Primer for The Fold Within Earth
## 5-Min Overview
The Fold is a static Markdown blog that becomes a P2P MUD when JS is enabled. Content in /atlas, built to /dist.
## 30-Min Deep Dive
- Schema: YAML front-matter in .md.
- Validation: foldlint.js checks schema, graphs, hashes, signatures.
- Build: Generates HTML with links, sanitizes Markdown.
- Witness: Ephemeral chat via WebRTC, offline localStorage.
- Scribe: Appends deltas atomically.
For full canon, refer to blueprint.
