From 076f3dfe7c59a73a5132d0711c883308478d5689 Mon Sep 17 00:00:00 2001 From: fylorn <249551762+fylorn@users.noreply.github.com> Date: Thu, 24 Sep 2026 16:53:22 +0800 Subject: [PATCH 1/2] refactor(gateway): run the request guards on core's tw-guard engines Core v0.43.0 moved this gateway's guard engines into the shared `tw-guard` crate. Switch to them and drop the copies here: - Hidden text: `tw_guard::hidden::scan_request` with `SMUGGLING`. The audit event's `found` items gain `revealed`, the text the tag characters spell. - Content filter: `tw_guard::content`. Stored rules keep their format (`security.content_filter_patterns`); each compiles through `Rule::new`, a bad one is skipped and the rest run. Rules are keyed by position, so two with the same name both report. The settings validator runs the same compile, so an empty pattern is now refused on save. Presets are core's built-ins grouped as injection / persona / chinese (were basic / strict / chinese). - Output length: `tw_guard::output` with byte counting, as before. The cap now also applies to streams: the frame that crosses it is not sent and the stream ends with an error in the caller's format (a Gemini JSON array ends with an error element and `]`). Cache hits are checked against the cap in force. Bumps tw-dialect, tw-guard and tw-breaker to v0.43.0 and removes `common::regex_util`, which nothing uses any more.
