# tests/test_security_headers_middleware.py
"""
Focused regression coverage for `SecurityHeadersMiddleware`
(core/middleware.py), added alongside the HSTS + Permissions-Policy
hardening:
1. HSTS is emitted only for HTTPS requests, including those reaching
the app over a reverse proxy (`X-Forwarded-Proto: https`).
2. HSTS is absent on plain HTTP so local/dev deployments are unaffected.
3. `Permissions-Policy` locks down camera/geolocation but preserves
same-origin microphone access (`microphone=(self)`), so the app's
own voice/STT flow (`getUserMedia({ audio: true })`) keeps working.
