2026-06-12 - The 121 AI Ledger v0.1 launch

v0.1 launch - methodology under iteration, corrections welcome

What changed: Launched /ai-ledger, /ai-ledger/daily, topic desks, method page, source index, corrections page, subjecthood desk method note, item pages, and root /changelog hook.

Why: L chose live-site review with honest labels after substrate-distant audits converged on day-1 discipline blockers.

Who made the change: Codex implementation from Cowork-CC dispatch using G build-with-reframe and R failure-mode mitigations

Ledger impact: 12 launch entries, 72 source-index entries, all nine source labels exercised, direct COI disclosures inline, no company scoring in the Ledger.
