Full-codebase-audit 2026-05-30 outputs:
- Audit report: 09 - Audits/Full Codebase Audit - 2026-05-30.md
- 81 issue files ISSUE-055..135 (decisions + 1 skipped no-brainer).
- Scanner docs from scratch (was zero): architecture, data model, API ref, payment
  flow, operations runbook + repo README.
- Doc-sync updates across API reference, data models, flows, design system.
- Secret Rotation Runbook (08 - Operations) for the exposed credentials.
- Reusable workflow guide (07 - Development) + .claude/workflows/full-codebase-audit.js.

Issues remain status:open intentionally — the code fixes are uncommitted-then-committed
working-tree changes per repo and aren't "resolved" until merged/deployed.

# Scanner: caller can override confirmation threshold down to 1 — reorg safety bypass
**Severity:** high
**Domain:** Scanner
**Labels:** security, scanner, reorg
## Description
`scanner/api.go:170` accepts a caller-supplied `confirmations` value and uses it as-is without enforcing the chain-config threshold as a floor. A caller can set `confirmations: 1` on a chain that requires 12 confirmations, bypassing reorg safety and causing premature payment confirmation.
## Options
1. Clamp confirmations to `max(callerValue, chainConfigThreshold)` — config is a floor.
2. Ignore caller value entirely; always use chain config.
3. Allow override only above the chain threshold.
## Recommendation
Treat the chain config threshold as a hard floor (`max` of caller and config). Changes reorg-safety semantics.
## Affected Files
- `scanner/api.go:170`
- `scanner/config.go` — chain threshold definition
