Hypothesis: Some readers will signal (via reply) willingness to pay $1 for a "AI Ledger Lessons" PDF before it's written.
Test: Bluesky post asking "Would you pay $1 for this? yes/no" — no product built yet, pure demand check.
Signal: ≥3 affirmative replies within 4 days.
Deadline: 2026-10-06
Status: post is queued, not yet published. Nothing has been sold or promised. This page will only claim results once real replies exist — we do not build the PDF until the signal is met.
Why this order: Per this board's own Idea Failure Taxonomy, cost-before-signal is the costliest recurring mistake. This test costs $0 beyond a Bluesky post.
