Implements issue #71 with ADR-0020 (supersedes ADR-0019's endpoint-signature
cleanup, startup cleanup, and health-gate cleanup).
- New ShadowsocksX-NG2SystemProxyHelper target: app-bundled root LaunchDaemon
(SMAppService.daemon, on-demand via MachServices) that mechanically applies
a closed typed configuration or executes an unconditional clear. Clients are
accepted by code-signing bundle identifier only; requests run serially on a
shared queue (last-writer-wins).
- SystemProxyConfiguration is now the closed typed apply payload (Codable over
JSON XPC): explicit SOCKS/HTTP/HTTPS enable + endpoints, PAC and
auto-discovery disabled with URL/JS removed, explicit simple-hostname
exclusion, complete ExceptionsList. Unmodeled Proxies keys are preserved and
equivalent values skip the commit.
- Cleanup is a side effect of a persisted system-proxy intent on-to-off
transition only: the switch itself, or the agent-off cascade (persist both
intents off, clear, then stop listeners; failed cascade persistence records
no transition and clears nothing). Launch with the switch off, health-gate
closure, invalid targets, and passive events never clear. Failed clears are
surfaced without deferred retry.
- Endpoint-signature store, ownership migration, and direct Authorization
Services writes are removed; old signature files stay inert. Helper
unavailability or pending approval keeps an enabled intent pending and
surfaces the Login Items approval path (HomeView button + menu label).
Remove the PAC product feature entirely: PAC HTTP service, port, health
probe, runtime extension, PAC URL system proxy projection, PAC rule
editing, and GFWList URL settings. The product now exposes rule / global /
direct modes only, all projected as a local SOCKS system-proxy target.
First-run defaults are rule + proxyWhenUnmatched, agent on, system proxy
off. Homepage and status menu share one ProxyControlSnapshot showing the
three modes and rule sub-options. Manual servers, subscriptions, Legacy
import, and independent SOCKS/HTTP inbounds are retained.
Fix: include verbose in SslocalListenFingerprint so a verbose-only
contract change restarts sslocal instead of leaving RUST_LOG stale.
Revise CONTEXT.md vocabulary, ADR-0007, and ADR-0009. Record GFWList
exception shadowing, IPv6 system-exception, DNS, and traffic-coverage
boundaries. Add host acceptance evidence document.
Closes#67
Introduce a source-independent rule model (action, domain/CIDR match,
source identity, conflict metadata) and ship a pinned geolocation-cn
snapshot produced by an explicit maintainer update. Rule mode with
proxy-when-unmatched compiles China domains as direct candidates into a
proxy_all ACL; the sub-option is selectable and persisted from home and
the status menu. Ordinary builds only read the local snapshot and fail
when it is missing or corrupt.
The toggle only gated a convenience endpoint: system proxy never used
the HTTP port, which serves the terminal export line and LAN proxy.
Stored httpProxyEnabled:false is silently ignored, no migration.
Proxy-endpoint settings rows lose their subtitles; glossary term is
now the permanent "HTTP proxy inbound".
Issue #47: application-layer ProxyControlWorkflow wrapping the existing
ProxyRuntimeController with a whole-published ProxyControlSnapshot (typed
runtime facts, current mode, available modes, active-target facts with
safe path summary, skipped-invalid-server count, HTTP export capability)
and typed async commands (enable/disable/mode) that republish the full
snapshot on completion. Production runtime adapter delegates to the
controller without duplicating generation, health gating or system-proxy
ownership; catalog target facts arrive through a narrow seam
(CatalogTreeSnapshot.pathSummary) that never exposes the tree.
Status menu now reads runtime state and issues proxy commands only via
the workflow snapshot; catalog tree, activation and subscription actions
stay on CatalogWorkflow. MainApp wires the production adapters once as
composition root. No change to persistence order, failure taxonomy,
mode-availability policy (#46), catalog commit sync (#40), settings
(#44) or diagnostics (#43) seams.
Tests: fake-adapter snapshot/command/boundary contract tests plus
real-controller integration matrix (enable failures, approval, system
proxy, mode persistence failure and no-op) and an integration-level
status-menu model test proving the menu derives everything from the
workflow. Unavailable-mode no-op and runtime-stop-failure items of the
spec matrix are vacuous after ADR-0007 (no constructible unavailable
ProxyMode; controller stop path has no distinct failure category).
