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: unbounded goroutine fan-out for webhook retries and reconciliation
**Severity:** medium
**Domain:** Scanner
**Labels:** bug, scanner, goroutine-leak
## Description
`scanner/main.go:130` spawns goroutines for retry and reconciliation fan-out without any concurrency bound. Under high load or many failed deliveries, the number of live goroutines is unbounded, risking OOM.
## Options
1. Bound with a semaphore/worker pool (e.g. `errgroup` with limit).
2. Process retries in batches sequentially.
3. Rate-limit outbound webhook calls globally.
## Recommendation
Introduce a bounded worker pool (`errgroup.SetLimit` or semaphore) for all retry fan-out paths. Coordinate with ISSUE-111.
## Affected Files
- `scanner/main.go:130`
- `scanner/webhook.go` — retry fan-out
