📝 WalkthroughWalkthroughThe Google Antigravity provider now permits base URL overrides. Secure transport validation rejects remote cleartext HTTP overrides. Tests cover routing, invalid URLs, local relays, HTTPS, and registry parity. ChangesGoogle Antigravity provider configuration
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to This change enables custom endpoints for an OAuth-backed provider, but the current validation can allow bearer credentials to reach a public HTTP endpoint when allowPrivateNetwork is enabled. That creates a high-impact credential exposure risk and should be fixed before merging. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

provider before the Google adapter sends its Authorization token, covering
baseUrl overrides accepted by router and config validation. Apply the
restriction only to OAuth/Antigravity or equivalent remote Google destinations,
preserving HTTP for providers that explicitly support local transport; update
the shared validation or Google adapter path rather than the registry metadata
alone.

CodeRabbit review (PR lidge-jun#2110): an http override would expose the OAuth bearer token in cleartext.

…tps enforcement Rebased onto dev @ fbc6f26 (single squashed commit; the previous branch history is re-applied in full). - registry: allowBaseUrlOverride: true on the google-antigravity entry; default baseUrl unchanged. - security (CodeRabbit + maintainer review): new providerSecureTransportConfigError in src/lib/destination-policy.ts — OAuth registry entries with allowBaseUrlOverride require https; cleartext http is allowed only for loopback/localhost/private relays behind the existing allowPrivateNetwork opt-in, which keeps the motivating http://127.0.0.1:47821 proxy working. Enforced inside providerDestinationConfigError, so routing, config validation, and the outbound layer share the gate; the lidge-jun#2071 https-rewrite stack can never observe a cleartext public destination. - tests: antigravity-baseurl-override covers override precedence, https rejection on both paths, and the localhost relay escape hatch; parity opted-in list gains google-antigravity.

🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift
Do not let allowPrivateNetwork bypass HTTPS for public destinations.
Line 155 returns before URL parsing and destination assessment. A configuration with baseUrl: "http://attacker.example" and allowPrivateNetwork: true therefore passes this function. The OAuth adapter can then send bearer credentials to a public cleartext endpoint.
Classify the destination before applying the private-network opt-in. Permit HTTP only after the destination is confirmed as localhost, loopback, or private. Preserve support for named private relays by enforcing the resolved-destination check before any outbound request. Add a regression test for a public HTTP URL with allowPrivateNetwork: true.
Based on learnings, OAuth adapters that attach Bearer credentials require separate HTTPS enforcement when cleartext transmission is unacceptable.

Thanks for both of these, @drakonkat — closing as superseded by #2148, which carries your implementation from #2109 and #2110 together: the registry opt-ins, the They were combined rather than landed separately because they share one byte-identical One correction, and it is the reason these needed a careful pass. Your gate returned before classifying the URL when if (providerAllowsPrivateNetwork(name, provider)) return null;So That was a genuinely good feature to add — being pinned to the registry endpoint is a real limitation for corporate gateways. The https requirement you already wrote was the right instinct; it just had a reachable bypass. Your work is credited in #2148's description. |

Problem
When a stale
baseUrlis saved inconfig.jsonfor thegoogle-antigravityprovider (e.g.http://127.0.0.1:47821from a proxy or a different account/region), ocx prints a warning on every run:There is currently no supported way to intentionally route this provider through a local proxy endpoint, and the warning cannot be silenced without hand-editing config.
Fix
Set
allowBaseUrlOverride: trueon thegoogle-antigravityprovider entry insrc/providers/registry.ts, consistent with other providers that already support endpoint overrides (alibaba, ollama, vllm, lm-studio, ...). The defaultbaseUrlis unchanged; behavior is identical unless the user explicitly configures an override.Security hardening (review follow-up)
Because
google-antigravityis an OAuth provider, an override endpoint receives bearer credentials. Per the CodeRabbit and maintainer review, this PR now also addsproviderSecureTransportConfigErrortosrc/lib/destination-policy.ts: OAuth registry entries that opt intoallowBaseUrlOverriderequirehttps:, and cleartexthttp:is accepted only for loopback/localhost/private relays behind the existingallowPrivateNetworkopt-in — which keeps the motivatinghttp://127.0.0.1:47821proxy working. The check runs insideproviderDestinationConfigError, so routing, config validation, and the outbound layer all enforce it before the Google adapter attaches its Bearer token. This also guarantees the #2071 HTTPS-rewrite stack can never observe a cleartext public destination. Keyed/local providers are untouched.Regression tests added in
tests/antigravity-baseurl-override.test.ts: http override rejected on the routing path and on the shared discovery/config gate, https override accepted, localhost relay escape hatch pinned.Companion PR for the same issue on the Anthropic Claude provider: #2109; it carries the same shared-policy commit so either merge order works.
