fix(server): provider updates on macOS use the system proxy - #25747
On macOS, a Dock-launched T3 Code has no HTTP_PROXY/HTTPS_PROXY in its environment. On a network that requires the proxy set in System Settings, provider updates (npm install -g, brew upgrade, opencode upgrade) therefore run unproxied and time out. The provider CLIs themselves keep working because they read the system proxy natively. On main, ProviderMaintenanceRunner spawns the updater with only the inherited env, so nothing ever applies the system proxy to it.
Change
Before each provider update on darwin, if neither the inherited environment nor the updater's own capability env sets HTTP_PROXY, HTTPS_PROXY or ALL_PROXY (in either case), the runner reads /usr/sbin/scutil --proxy with a 2 s timeout:
An enabled HTTP proxy becomes HTTP_PROXY/http_proxy=http://host:port for the update command, and an enabled HTTPS proxy becomes HTTPS_PROXY/https_proxy the same way.
NO_PROXY keeps the updater's or inherited entries (lowercase first, as curl reads them), then adds loopback and the macOS exception list. A bypass-all no_proxy=* skips the system proxy entirely.
SOCKS and PAC are not used.
If scutil fails, times out or reports no proxy, the update runs exactly as before.
Linux and Windows spawn nothing new. The value is read on each update, so changing the system proxy takes effect without restarting the app.
vp test run apps/server/src/provider/macosSystemProxy.test.ts apps/server/src/provider/providerMaintenanceRunner.test.ts: 25 passed.
Red on main (412c128): passes the macOS system proxy to the updater when the env has none failed with expected undefined to equal 'http://127.0.0.1:7890'. It passes with the fix.
Further runner tests cover four cases:
An inherited proxy, or an updater that declares its own proxy, skips scutil and leaves the env alone.
An updater's NO_PROXY (Grok and Muse pass the whole env) is merged into the bypass list.
no_proxy=* skips the system proxy.
Removing each guard makes its test fail.
Parser tests cover disabled, incomplete, SOCKS and PAC entries, scoped per-interface dictionaries, IPv6 hosts, and the NO_PROXY merge.
Runtime transcript (Linux, at f7e512c):npm view @openai/codex version without the env main gives the updater left a local CONNECT-logging proxy with 0 connections. With the env parseScutilProxy produces for that proxy, npm went through it (PROXY RECEIVED: CONNECT registry.npmjs.org:443). transcript.txt, driver scripts proxy.py and parse.ts.
Parser complexity: a single linear pass, plus two anchored regexes with bounded, non-overlapping groups. Malformed 3000-token inputs parse in under 10 ms.
Evidence table: none. This is a server-only change with no visible surface, so there are no captures.
cannot-verify macos: no macOS machine was available. A real scutil --proxy output, a Dock launch and a brew/npm update behind a System Settings proxy were not exercised.

…r updates
This test reproduces #2709: on darwin, with no proxy variable in the
inherited environment, the provider updater is spawned without the
HTTP(S) proxy configured in macOS System Settings (scutil --proxy).

A Dock-launched desktop app has no HTTP(S)_PROXY in its env, so
`npm install -g`, `brew upgrade` and `opencode upgrade` ran unproxied and
timed out on networks that need the proxy set in System Settings.
On darwin, when the inherited env has no HTTP_PROXY, HTTPS_PROXY or
ALL_PROXY (either case), each update now reads `scutil --proxy` (2 s
timeout, any failure means no proxy env) and passes the enabled HTTP and
HTTPS proxies as HTTP(S)_PROXY/http(s)_proxy, with NO_PROXY from the
exceptions list plus loopback. The capability's own env still wins.
Linux and Windows spawn nothing new.
Fixes#2709

… macOS system proxy
A capability that declares its own proxy now skips the system proxy entirely,
so a generated lowercase https_proxy cannot shadow it for curl. An inherited
NO_PROXY is merged into the generated list instead of replaced, and npm's
bracketed IPv6 loopback is bypassed too.

Providers that pass their whole environment as update.env (Grok, Muse) no
longer overwrite the merged bypass list, the lowercase no_proxy wins as it
does for curl, and NO_PROXY=* skips the system proxy entirely.

Macroscope's review found this PR requires human approval — macOS provider maintenance commands now automatically use compatible system proxy settings when no explicit proxy is configured. This changes default network routing for existing users and requires confirmation of that product behavior.

Walkthrough
Provider update commands now receive eligible macOS system proxy settings. The change parses scutil --proxy output, merges discovered values with the update environment, and adds tests for parsing and environment precedence.
Changes: Provider update proxy handling
Layer / File(s)
Summary
Parse system proxy settings apps/server/src/provider/macosSystemProxy.ts, apps/server/src/provider/macosSystemProxy.test.ts
The parser converts supported top-level HTTP and HTTPS settings and exceptions into proxy environment variables. Tests cover ignored inputs, exception handling, and merged NO_PROXY values.
Gate and read system proxy settings apps/server/src/provider/macosSystemProxy.ts
The discovery function skips lookup when platform or environment conditions exclude it. Otherwise, it runs scutil --proxy and parses the output.
Pass proxy settings to provider updates apps/server/src/provider/providerMaintenanceRunner.ts, apps/server/src/provider/providerMaintenanceRunner.test.ts
The runner merges discovered settings with the update environment. Tests cover existing proxy settings, bypass values, and system proxy values.

It does not include an explicit maintainer approval comment, but the description is otherwise substantially complete.
Full details: Linked Issues check
Explanation
PR #2709 requires provider maintenance subprocesses to use the macOS system proxy. providerMaintenanceRunner.ts calls readMacosSystemProxyEnv before each update. macosSystemProxy.ts runs /usr/sbin/scutil --proxy only on Darwin when no inherited or updater proxy exists, maps supported HTTP/HTTPS settings, merges NO_PROXY, and preserves the existing behavior on failure, timeout, SOCKS, PAC, or unsupported bypass entries. The reported 25 focused tests cover the runner guards, proxy propagation, bypass merging, parser cases, and failure paths.
Full details: Out of Scope Changes check
Explanation
The changed files support PR #2709. The parser, macOS lookup, runner integration, and automated tests implement or verify proxy propagation for provider update commands. The platform and environment guards prevent unrelated subprocesses and non-macOS behavior changes. No unrelated product change is evident.

The automated pipeline stopped on this pull request and will not merge it:
the reviewers still had findings after 3 rounds (the work is on main...fix/issue-2709):
[major] apps/server/src/provider/macosSystemProxy.ts:68: Worse than main: passing CIDRs through NO_PROXY does not preserve npm's bypass behavior. Injecting HTTP_PROXY sends requests for a private-IP npm registry through the proxy, breaking updates that currently connect directly. Confirmed with actual npm requests: main's unchanged environment returned package metadata successfully; this head's generated environment contacted the proxy and failed with E502.
Fails with: A macOS environment without explicit proxy variables, an enabled system HTTP proxy, ExceptionsList containing 192.168.0.0/16, and npm configured with registry=http://192.168.122.48:. A corporate proxy that cannot reach that private registry returns 502. Corporate users with npm-installed providers hit this during updates.
…ranges
npm matches NO_PROXY by hostname suffix and ignores CIDR and wildcard IP
entries, so passing the system proxy would send a bypassed private
registry through the proxy. When the exception list holds such an entry
(other than the default link-local range), the update runs as before.
Also fold the runner's skip-case tests into one table.

65-67: Trivial · Maintainability & Code Quality
Log a debug message when a macOS proxy exists but the parser discards it.
parseScutilProxy returns {} when any exception contains / (other than the link-local range) or *. The update then runs without a proxy, as it did before. Users on corporate networks with CIDR bypass entries get no signal that the system proxy was ignored. The updater times out as in issue #2709, and nothing in the logs explains why.
Log at debug level in readMacosSystemProxyEnv when output is non-empty and the parsed result is empty. Include only a category, such as unrepresentable-exception. Do not log the raw scutil output or the host names.

npm cannot match IP ranges or dotless hosts in NO_PROXY. Apply the
existing guard to the inherited and updater NO_PROXY entries too, and keep
the direct connection when macOS excludes simple hostnames.

Preserve the effective lowercase bypass value
If inherited no_proxy=* and the updater supplies only NO_PROXY=registry.corp, the reader can enable the system proxy and replace no_proxy=*. A lowercase-first updater can then send requests through the proxy instead of bypassing it. Select the bypass value from the effective environment before applying the bypass-all guard.

Update the noProxy selection in macOS system proxy handling to preserve the effective lowercase bypass value when the updater provides only uppercase NO_PROXY.

npm sends plain-HTTP requests via https_proxy and falls back to
HTTP_PROXY for HTTPS, so a proxy enabled for only one protocol, or
different HTTP and HTTPS proxies, would reroute traffic macOS sends
direct. Pass the system proxy only when HTTP and HTTPS share one.
