Merge Risk: 🟡 Moderate · up to Some local and link-local web-search requests can still go through the configured proxy, particularly when lowercase no_proxy is inherited. Correct the macOS bypass handling before merging to avoid misrouted or failed requests. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Mac users can now route outbound requests through a system proxy, but some system bypass rules may not take effect as intended. Under a narrower combination of inherited bypass settings, an outbound safety check may also disagree with the route the request actually takes. Retained concerns

Apply discovered exceptions to the effective lowercase bypass list.
If the process inherits a nonempty no_proxy, mergeNoProxyEntries puts systemNoProxy only in NO_PROXY. Bun reads NO_PROXY only when lowercase no_proxy is unset or empty. A host in macOS ExceptionsList can therefore still use the discovered proxy. The test at tests/server/proxy-env.test.ts Lines 575-582 exercises this state but asserts the ineffective lowercase list. Add discovered exceptions to nonempty no_proxy as well, and assert that an exception appears in the effective list. Keep the existing treatment of configured entries separate. (bun.sh)

Holding approval for two decision-critical items. The parser/selection controls are bounded, but effective bypass precedence is unresolved: with inherited lowercase no_proxy, discovered macOS ExceptionsList entries are added only to uppercase NO_PROXY; Bun native fetch prefers lowercase while the custom matcher reads uppercase. Base code intentionally preserves lowercase authority to avoid silently widening direct egress, so the open suggestion should not be applied mechanically. Please record the intended precedence contract and prove it through exact-head macOS native-fetch plus custom-transport proxy/bypass tests. Required exact-head runtime/macOS CI is also absent.
This reverts commit 3e9aa99.
This batch leaves six non-GUI enhancements on the current `dev` base as one squashed commit per contributor PR. Idle Codex accounts can start a fresh five-hour window on a real request; the Windows tray gains Chinese text; CONNECT can enforce an exact destination allowlist and a shorter CA lifetime; an on-demand native queue helper gains cross-platform offline CI; Gemini video retains its agentic mode; and GJC model exports expose supported reasoning levels. | PR | Change | Author | | --- | --- | --- | | #5949 | Idle five-hour window activation | codingbo; Terry Tan credited for earlier overlapping work | | #5884 | Windows tray Chinese localization | Yum-wu | | #5934 | CONNECT destination allowlist and CA lifetime option | luvs01 | | #5829 | On-demand native queue helper and offline workflow | luvs01; Epinephrine | | #4663 | Gemini agentic video passthrough | Abhishek Sharma | | #5431 | GJC reasoning controls in model exports | 이재현 | Integration commit `116cc6c37c` documents GJC's exported effort controls in the English guide and all seven translated guides. Commit `b93e2524b5` updates the older GJC schema guard for those exported fields; commit `b900ce73c1` fixes the queue helper's help-probe watchdog and adds a timing regression. No file under `gui/` changed. **Left out:** #5893 was reverted in `5a96cade33` and remains open. Its macOS system-proxy exceptions (`*.local` and CIDR ranges) were copied into `NO_PROXY`, but Bun fetch does not honor those patterns; a populated lowercase `no_proxy` can also override the merged value. It needs translation or CIDR routing across transports and a proxy-contact regression before integration. Review the remaining security-sensitive diff at `src/codex/routing.ts` and `src/codex/routing/idle-window.ts` (account selection), `src/claude/intercept/connect-proxy.ts` and `local-ca.ts` (CONNECT policy and certificates), `src/adapters/google.ts` (video URI forwarding), and `.github/workflows/codex-queue-helpers.yml` plus `scripts/codex-queue.sh` and `.ps1` (workflow permissions and explicit message destination). The new workflow grants `contents: read`, pins checkout to a full SHA, disables credential persistence, and runs the Node test on Linux, macOS and Windows. Independent review of the revised head is pending before merge.

Qualify the no-proxy environment-preservation claim in all seven translations.
When proxy is unset, applyProxyEnvWith preserves inherited proxy variables. It can still add loopback entries to NO_PROXY for an inherited SOCKS or HTTP(S) proxy, and may also update lowercase no_proxy.
The wording “the existing environment is preserved” implies that no environment variable changes. Replace it in:
docs-site/src/content/docs/fr/reference/configuration/server.md:276docs-site/src/content/docs/ja/reference/configuration/server.md:187docs-site/src/content/docs/ko/reference/configuration/server.md:246docs-site/src/content/docs/ru/reference/configuration/server.md:235docs-site/src/content/docs/tr/reference/configuration/server.md:307docs-site/src/content/docs/zh-cn/reference/configuration/server.md:201docs-site/src/content/docs/zh-tw/reference/configuration/server.md:220
Use wording that limits preservation to inherited proxy variables and states that loopback entries may be added to NO_PROXY. The English canonical page already uses this narrower meaning.

Thank you @codingbooo for macOS system proxy discovery. It landed on dev through #6124 (merge commit 296f0ce), with your authorship recorded in Co-authored-by trailers. The carry reads scutil once for proxy: "auto", translates *.domain and IP exceptions only where Bun and the WebSocket matcher agree, drops only the default link-local ranges with a notice, and refuses before any environment write for anything it cannot represent. Closing this PR as carried; the full review trail is on the lane PR linked from #6124. |
