In a gated scope, the two HTTP clients the platform owns connect only to
addresses that a pin or a stored exemption covers at the moment of the
connection, on every hop.
- intercept.PinnedDialer(tool, scoped): the DialContext of both clients.
It reads the target scope from the context net/http passes to the dial.
Gate off, or no scope in a client built without one: plain dial, as
today. A client built for a scope whose scope is missing at the dial
fails closed with TARGET_GATE_UNAVAILABLE.
- dialTarget runs the gate decision on the dialled host:port with a fresh
lookup (block rules first, exemptions, pins, port precedence) and
connects only to the addresses it compared, never to the name. Derived
exemptions and name-only pins dial the address as received. An address
no pin covers finds or opens the request (new_ip / no_pin, wait 0) and
fails at once with TARGET_APPROVAL_PENDING. Redirect hops are dialled
against the hop's own (host, port).
- WebFetch (withWebFetch, now given the run context): DialContext set on
every agent kind; DisableDirectRetry when the run's scope is gated.
- Custom http tool: a direct call in a gated scope gets a DefaultTransport
clone with the pinned dialer, no environment proxy and keep-alive off.
Proxied calls are unchanged (the recording proxy is step 2.2).
- Name-only: request reason says the platform does not bind the
connection; the first-use pin_match row records the effective state.
- Derived exemptions: a proxy URL without a port is listed with the port
net/http dials (1080 for socks5) (OPEN-9).
- go.mod: Norma v0.4.8 (DialContext, DisableDirectRetry).
