Summary

Preserve unrelated authenticated loopback proxies when baking service environments. A proxy's username and address shape do not establish ownership; exclude only the canonical Claude intercept URL authenticated by this installation's existing token.

Ownership is independent of the current configured port, so an inherited URL from a still-bound older port is also excluded after configuration changes. Other credentials, users, hosts, schemes and malformed URLs remain untouched. The lookup neither creates nor logs a token.

Verification

  • Pinned Bun 1.4.3, official queued runner: new default-path regression 4 passed / 27 assertions / 0 failed. It failed in two cases before the fix.
  • Existing service tests passed. After materializing one unchanged inventory file omitted by the sparse checkout, the proxy/layout batch passed 138 tests, 4 existing platform skips, 0 failures.
  • TypeScript, structure, privacy, changed-file size and whitespace checks passed. The independent follow-up review found the port-drift and unrelated-proxy cases covered without broadening ownership to username alone.
  • Current-head hosted CI passed at e7d17395b55da58271809ab8a26f8ece98ccb27e, including all four selected test shards. The full local suite and real native service installation were not run under the repository's resource exception.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Runtime ownership documentation and test-layout registrations are updated.
  • Existing credential reads and URL ownership checks received independent review.

Review readiness

  • Required validation passed with scope and limitations documented.
  • Branch freshness was checked against dev at 0706074b8065c80cbfe23a475c70a1b4530a5a36: four dev commits ahead, within the allowed ten-commit window.
  • The reported configured-port drift is fixed and regression-tested.
  • Current-head CI passed and maintainer approval is recorded. Merge/platform policy remains separate.

Summary by CodeRabbit

  • Bug Fixes
    • Proxy configuration now distinguishes this app’s intercept proxy from unrelated proxy settings, even when its port changes. This prevents the app’s own proxy from being selected as an external proxy while preserving other valid proxy settings.
    • Proxy URLs with invalid ports, malformed values, or unrecognized ownership are no longer incorrectly treated as this app’s proxy. When the app’s proxy is excluded, a valid HTTPS proxy can still be used as a fallback.

📝 Walkthrough

resolvedProxyEnv accepts an optional Claude intercept proxy URL. When provided, it excludes exact matches. Otherwise, it checks proxy values against the installation token, opencodex username, 127.0.0.1 host, and valid port. Tests and runtime documentation cover these rules.

Changes: Proxy environment filtering

Layer / File(s) Summary
Resolve and filter the installation proxy
src/service/definition.ts, structure/runtime.md
resolvedProxyEnv accepts an optional intercept URL. Without one, it checks proxy URLs against the installation token and requires the exact opencodex username, 127.0.0.1 host, and a port from 1 through 65535.
Validate proxy filtering
tests/service/service.test.ts, tests/service/service-proxy-env.test.ts, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
Tests cover owned URLs across environment key variants, nonmatching or malformed URLs, and absent or invalid tokens. The test layout and expected fixture include the new test file.

Reviewed exact head e7d17395b55da58271809ab8a26f8ece98ccb27e against dev, including all six changed files and the existing pinned token reader. Ownership now requires this installation's usable existing credential and the canonical loopback URL components, rather than the opencodex username/address shape alone. This preserves unrelated authenticated proxies while still excluding an inherited owned URL after configured-port drift. The default reader does not create, rewrite or harden a credential during this inspection. No blocking issue found in this scope.

The regressions exercise the default lookup, configured-port drift, unrelated credentials/components, fallback spelling and absent/unusable-token no-creation controls. I independently inspected current-head hosted run 39731595298: gates/typecheck, all four selected Ubuntu shards and structure succeeded; the Service lifecycle workflow also completed. No additional local suite, real service installation or native OS acceptance was performed for this review. Skipped Windows/macOS lanes remain explicit coverage limits; merge/platform policy is separate.

Merged on the owner path (squash, --match-head-commit 556889945c). Windows-sensitive, so rule C applies: ci.yml lane=all run 39832432710 on this exact head has every test, Windows, macOS and gate job green; only the final ci aggregate job was still waiting for a runner behind a 200+ run queue, and it only re-checks those same job results. PR checks are green, review threads are resolved, and a squash simulation onto current dev (with the other merge in this batch) passed typecheck, structure:check and the changed test files.
