TrustToken describes a hands‑on workflow: run audits, formal verification and bug bounties in parallel against one commit, inject bugs and hash them so auditors can’t claim post hoc finds, and use capture‑recapture estimators to quantify missing issues. A Chapman/Lincoln‑Peterson style estimate puts total bugs at ~23 when 21 are found; formal verification catches 17, auditor A finds 8 (3 overlap injected), auditor B finds 1, bounty program performs poorly. Concrete outcome is replacing auditor B, reworking the bounty, and pausing releases until estimated residual bugs drop, capture‑recapture (Chapman, Lincoln‑Petersen).
