Review comments at @docs/security-threat-model.md:
- Line 229: Update the severity guidance in the threat-model entry so an
accepted V1 downgrade when DisableV1=true is classified as Critical, reflecting
unauthenticated vote creation in v2-only mode. Narrow the existing High entry to
cover only its other listed threats, and preserve the note that the current
parser rejects V1 when disabled, so this is not a claim of a current bypass.

## Security threat model
For security reviews, vulnerability triage, and security-sensitive changes, read `docs/security-threat-model.md` before classifying or fixing findings. Treat it as the repository-specific attacker/trust-boundary model; verify every conclusion against current code and tests. Do not promote compatibility, trusted-operator behavior, or generic correctness bugs into security findings unless the documented boundary is actually crossed.

Summary
Notes
Documentation only; no runtime behavior changes.
The model reflects current hardening such as bounded listener/forward queues, trusted proxy handling, packet/header bounds, and V1 disable support so Codex tests those controls for bypasses instead of re-reporting their old absence.
