Codex P2 on #1364, extending the `localhost.` fix into `isStalkerStreamCredentialSafe()`. It compared hostnames literally, so a portal on `portal.example` serving `https://portal.example./movie.mkv` classified its own stream as third-party. Wider than the download guard it was reported against: this predicate is the single rule BOTH the renderer playback-header builder and the Electron main-process fallback use to decide whether a stream may carry the mac cookie and Bearer token. A portal-owned stream spelled with the root dot was getting the credential-free profile and would 401 — pre-existing, and exactly the "only VLC works" class this contract exists to prevent. My PR added two new dependencies on the same predicate (the download static guard and the portal-owned fallback), which is how it surfaced. Both sides are normalized, so it stays symmetric, and it can only widen toward "same host" — never toward handing credentials to a different one. A test pins that `evil.portal.example.` is still rejected. Also carries the authority guard found by probing the same class myself rather than waiting for it to be reported: `http:///ch/1` has no authority and `URL` quietly reinterprets the first path segment as the host, so a malformed command reached the player as a nonsense address instead of going to the portal. `isPlayableHttpUrl()` now requires a non-empty authority. The other exotic spellings I probed were already covered — `URL` canonicalizes `127.1`, `2130706433` and `0x7f000001` to `127.0.0.1`, uppercases and expanded IPv6 normalize too.
