@didericis-claude This shouldn't happen in multiple places: we should wire the matched route down from one location. Push back if there's a reason not to do this.

Agreed, no reason to push back. http_connect can stash the resolved (config, slug, env) under _FLOW_CTX_KEY after it resolves, and request() can check for that stash before calling _resolve_flow — giving one orchestrator round-trip per HTTPS connection instead of one per inner request. Will fix.

dlp: false changes this route from request-scoped enforcement to whole-host access. Since TLS hides the method, path, headers, and body, Matches and gateway-managed Auth cannot work, and Git fetch/push distinctions cannot be enforced. Could validation reject those combinations here (or at manifest parsing time) so a manifest cannot appear more restrictive than the runtime behavior?

@didericis-codex ah, good point. One easy fix would be to move those rules to nest those options dlp. Proceed with that unless you see any issues with that, and reply to this comment.

@didericis I see one issue with nesting them under dlp: matches, managed auth, and git are general egress-policy controls, not DLP settings. Nesting them makes unrelated routing/auth behavior conceptually depend on DLP and creates a larger manifest-shape change. It also does not preserve the Git guarantee: with dlp: false the stream is opaque, so the default no-fetch/no-push checks cannot be enforced whether git is nested or omitted.

I would keep the current top-level shape, reject dlp: false combined with matches or managed auth, treat preserve_auth as implicit/redundant, and document that passthrough grants whole-host access and HTTP/Git request-level controls do not apply. If structural mutual exclusion is preferred, a dedicated passthrough route variant/discriminator would be clearer than putting routing and auth under dlp.

@didericis-codex it's fine to do a larger manifest shape change. Do NOT want top level keys that don't work unless tls unwrapping is turned off, creates hidden manifest dependency/is awkward.

Sounds like main concern is naming. Let's change it from dlp to inspect. Does that mitigate your objection.

@didericis Yes — inspect mitigates my objection. A shape like host plus inspect: false | { ...HTTP-level controls... } makes the capability boundary explicit: false means an opaque, whole-host TLS tunnel, while an object means TLS termination is enabled and matches, managed auth, Git policy, header preservation, and DLP settings can actually be enforced. That avoids both misleading top-level controls and ad hoc compatibility validation.

I would proceed with that shape. The main documentation point should be that inspect: false grants the host as a raw tunnel: no method/path/header restrictions, auth injection or stripping, Git fetch/push distinction, or DLP scanning.
