@didericis-codex ah, good point. One easy fix would be to move those rules to nest those options @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-codex

@didericis I see one issue with nesting them under I would keep the current top-level shape, reject @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 @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-codex
commented
@didericis Yes — I would proceed with that shape. The main documentation point should be that @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.

@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_connectcan stash the resolved(config, slug, env)under_FLOW_CTX_KEYafter it resolves, andrequest()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.
