Security Audit Report: Islandflow

Executive Summary

Stage 15 final report assembly completed for the Islandflow /piolium-deep audit workspace. The repository presents a multi-service market-data platform with public web/API/WebSocket entrypoints, NATS/JetStream eventing, ClickHouse/Redis persistence, ingest workers, synthetic-admin controls, and an Electron shell. No promoted final finding directories were present under piolium/findings/ during this assembly, so this report consolidates the available attack-surface and methodology artifacts rather than listing confirmed packaged findings.

Findings by Severity

• Critical: 0
• High: 0
• Medium: 0

No promoted confirmed finding directories were present under piolium/findings/ at assembly time. Earlier-stage candidate and chamber outputs remain available under piolium/findings-draft/, piolium/chamber-workspace/, and piolium/adversarial-reviews/, but no standalone report.md finding packages were available to link as final confirmed findings.

Attack Surface Summary

The audit identified the primary exposed and security-relevant surfaces as: unauthenticated market-data REST and WebSocket routes in services/api, Next.js synthetic-admin proxy routes, external feed ingestion paths, NATS/JetStream subjects and KV state, ClickHouse query/insert sinks, Redis live/candle caches, Electron navigation/open-external boundaries, and Docker/edge deployment bindings.

Key supporting artifacts:

• Knowledge Base / Threat Model
• Architecture Entrypoints
• Manual Attack Surface Inventory
• Public Routes Authorization Matrix
• Source/Sink Flow Review
• Cross-Service Edges
• Candidate Scan Summary
• Advisory Summary
• Patch Bypass Summary
• Spec Gap Summary
• State/Concurrency Summary
• Variant Summary

Coverage Gaps

• piolium/findings/ was not present or contained no promoted finding packages at final assembly time; therefore no final per-finding reports or PoC links could be included.
• Candidate drafts and review evidence exist outside the promoted findings directory and should be reviewed before treating this as a no-findings audit result.
• Final report completeness depends on prior-stage promotion from drafts to piolium/findings/<ID>-<slug>/report.md; that promotion was not observable in this workspace.

Methodology Notes

The audit followed the deep piolium workflow: advisory and architecture reconnaissance, attack-surface inventory, candidate scanning, custom SAST/source-sink review, structured review chambers, adversarial verification for higher-risk candidates, and final assembly. Chamber evidence is available at piolium/chamber-workspace/index.md, with cluster debates covering news XSS, data exposure, synthetic admin proxying, concurrency, and infrastructure/bus risks. Static and structural analysis artifacts are available under piolium/codeql-artifacts/, piolium/semgrep-rules/, and piolium/attack-surface/.

Assembly Checks

• Finding report size check: passed for every directory under piolium/findings/ that existed; no promoted directories were found.
• Required final report written: piolium/final-audit-report.md.
