Forthcoming · Q3 2027 launch target
Notify me at launch
Calibration Ledger launches Q3 2027 — public registry of calibrated-accuracy scores for predictive sources. The launch is gated on four prerequisites; if three of four don’t clear, the project is sunset rather than zombie-maintained, and you get one email saying so. Either way, you hear once.
Two ways to subscribe
1. Email — one message at launch
Send an email to contact@calibrationledger.com with subject Notify me at launch. The body can be empty — the subject line tags it. No double-opt-in, no marketing automation, no follow-up email until launch (or the kill-criterion announcement, whichever comes first).
2. Atom feed — every methodology + site revision
Want continuous updates on methodology + site versions, not just one launch notification? Subscribe to the changelog Atom feed in your RSS reader (Feedly, Inoreader, NetNewsWire, etc.):
https://calibrationledger.com/feed.xml
Every commit-level methodology revision lands in the feed within minutes of deploy. No tracking, no third-party server in between.
Privacy
Email subscriptions are stored manually in a list owned by the operator — no third-party email service, no analytics tracker on subscriber emails, no behavioural profiling. Subscriber count + the list itself stay private until launch.
At launch (or kill-criterion fire), one email is sent. After that the list is archived — never re-used for any other purpose. To unsubscribe before then, reply to any prior email with subject unsubscribe or email contact@calibrationledger.com with subject unsubscribe.
