Summary
Remediates all ten validated findings from the repository-wide Codex Security scan of
origin/main, plus every issue found during repeated exact-head security and compatibility review of the remediation branch.The final integration pass additionally:
503to ordinary followers while rejecting Engine.IO followers before they retain transport or socket capacityThe broader remediation also hardens MFA bootstrap, OAuth/account step-up, Tailscale SSH target and interface authority, backup/restore durability, Socket.IO and terminal bounds, SFTP parsing and pagination, SMB transport and namespace integrity, transfer ownership/cancellation, saved-connection storage and recovery, audit redaction, session aliases, and deployment defaults.
Compatibility guardrails
Test-suite consolidation
The final commit removes 14 redundant test cases and 160 net test lines without changing production code or removing a security boundary from coverage.
Exact-head validation

7adaca24-2bc7-43e5-98b8-ebcac96159c8) reviewed all 66 authoritative changed-source items on the preceding application-code head and completed with full coverage, zero reportable findings, and zero deferred findings. The final test-only follow-up received its own completed Codex Security diff scan (7dbd9246-bf5f-434f-8d7a-40aa235ce3bb): all three changed coverage surfaces were reviewed with zero findings and no production-source change.Review posture and remaining target-specific checks
The immutable patch-risk assessment recommends merge after human review; automatic merge is intentionally not recommended because this is a broad, security-critical change touching authentication, remote-file mutation, persistent-state migration, deployment behavior, and public browser/runtime contracts.
Local evidence does not replace environment-specific canaries for the deployment's real LDAP provider, an end-to-end Tailscale peer, a concurrent two-principal live SMB race/Windows SMB server, Firefox/Safari, or an operational schema-v3-to-previous-version rollback rehearsal. These are recorded rollout checks, not unresolved code findings.
