Summary: Substack is the canonical long-form platform in the cross-posting hierarchy. It supports native footnotes, LaTeX math, code blocks, image galleries, audio embed, and paid subscriptions. Publishing workflow: write in wiki → export to Substack with canonical URL → distribute condensed versions to LinkedIn/X.

Platform Role in Hierarchy

Owned Domain (ahsan.ai) ← canonical
       ↑
Substack (ahsan.ai subdomain or custom) ← canonical for newsletter
       ↓ syndicate
LinkedIn Article (condensed, link to canonical)
       ↓
X/Twitter Thread (section-by-section, link in reply)

Publishing Workflow

1. Write in Wiki (Source of Truth)

  • File: wiki/blogs/slug.md
  • Frontmatter: full schema (title, slug, tags, sources, related_concepts)
  • Content: Full depth with Mermaid, LaTeX, code, tables
  • Internal links: <span class="wikilink unresolved">concept-slug</span>

2. Export to Substack

  • Manual: Copy Markdown → Substack editor (preserves most formatting)
  • Automated (future): Script wiki → Substack API
  • Canonical URL: Set in Substack post settings → https://ahsan.ai/blog/slug

3. Configure Canonical

<!-- In Substack post settings -->
<link rel="canonical" href="https://ahsan.ai/blog/slug" />

4. Publish & Distribute

Platform Format Timing
Substack Full post + email Day 0
LinkedIn Condensed post (template) Day 0–1
X/Twitter Thread (1 tweet/section) Day 0–1
Owned Domain Full HTML (wiki → HTML) Day 0
