Report written to `loop/pentest/security-assessment-report.md`.

**Summary of what's in the report:**

- **21 confirmed findings** across 4 severity levels (6 Critical, 7 High, 5 Medium, 3 Low)
- Full exploitation evidence with request/response pairs for every finding
- Root cause analysis showing AUTH-001 (no session management) as the single point of failure — fixing it blocks 15 of 21 findings
- A documented attack chain demonstrating full node takeover in 6 curl commands
- Prioritized remediation table (P0 within 48 hours through P2 within 1 month)
- Appendix with excluded findings, technology inventory, and dependency tree of vulnerabilities

The most critical takeaway: the existing session middleware in `core/startos/src/middleware/auth.rs` just needs to be wired into `core/archipelago/`'s HTTP handler. That single integration addresses the root cause of nearly every finding.
