The downloadable build signs Developer ID, which permits the tunnel entitlement only in its system-extension form, so that build compiles the same provider sources into a system extension while every other build keeps the app extension the harness and CI exercise. The entry point compiles behind CELL_TUNNEL_SYSTEM_EXTENSION so both modes carry the same file list and the dead-code gate keeps its coverage. Set ARCHS to arm64 in the project and in the external package settings. The vendored WireGuard bridge is built for Apple silicon alone, so an Intel slice had nothing to link against.

Manual signing needs a profile named for every target carrying App Groups, and the Catalyst slice had none in the Developer ID mode, so the release build stopped there. It signs against CellTunnelPhone Tart Catalyst Direct, which covers io.goodkind.CellTunnelPhone on macOS and lists no devices. Co-authored-by: Claude <noreply@anthropic.com>
A packet tunnel packaged as a system extension does not exist for NetworkExtension until macOS activates it, so the agent submits the activation request in loadOrCreateManager, which every start path reaches. The build that ships an app extension logs the skip, because macOS registers that provider from the app bundle. Co-authored-by: Claude <noreply@anthropic.com>
The release signs three targets and one GitHub secret holds at most 48 KB, which the agent and tunnel provider profiles nearly fill, so the Catalyst profile travels in APPLE_DEVELOPER_ID_PROFILE_CATALYST_BASE64 and joins the other two on its own line. The shared pipeline installs one profile per line. A caller passes either inherited secrets or a named map, never both, so naming the profile value means naming every secret the pipeline reads. Co-authored-by: Claude <noreply@anthropic.com>
A request holds its delegate weakly, so the local delegate had no owner once submitRequest returned and macOS could report the outcome to a deallocated object, leaving the caller suspended with no tunnel and no error. The delegate now holds itself until a callback resumes the caller. Cancelling the caller resumes it with CancellationError, because macOS cannot withdraw a submitted request, and a lock guards the single resume across the cancelling thread and the main queue. Also replaces the nested signing-mode ternary in Project.swift with an explicit chain, and rewrites the run.md section that still described the release as unable to use a system extension. Co-authored-by: Claude <noreply@anthropic.com>
Notarization returned Invalid with two kinds of error: every binary in the app lacked a secure timestamp, and the agent and system extension requested get-task-allow. Xcode signs during a plain build the way it signs for running locally, passing --timestamp=none and writing the debugging entitlement into the entitlements it generates. Project.swift sets OTHER_CODE_SIGN_FLAGS to --timestamp and turns off base entitlement injection for the whole project in Developer ID mode, and Tuist/Package.swift applies the timestamp flag to the vendored WireGuard frameworks, which notarization checks as well. Both stay off in every other build, where a timestamp would contact Apple's timestamp server on each signing and dropping the debugging entitlement would stop a debugger attaching.

Compare
Every thread from this review is answered and resolved, and the branch has moved on since it was written. The two findings that were real, the activation delegate lifetime and the stale run.md section, are fixed. The rest were refuted with evidence in their threads. The signed pipeline now runs end to end: all three Developer ID profiles install, every macOS target signs, and Apple returns Accepted for both archives.

Problem
Because Apple grants the Network Extension entitlement to Developer ID provisioning only in its system-extension form, this app could not produce a signed download at all. The tunnel ships as an app extension, so the release stopped at the entitlement mismatch and nobody could install the product without a toolchain.
This PR makes the downloadable build package the tunnel as a system extension and activate it, so the release signs, notarizes, and runs. Development, CI, the second-Mac harness, the provider class, the agent, the relay, and the loopback dial to the agent are all unchanged. Only the Developer ID build swaps the product type and the entitlement strings.
A system extension does not exist for NetworkExtension until macOS activates it, and only an app in
/Applicationsmay request activation for an extension inside its own bundle. So the agent submits that request before it resolves a tunnel profile, and macOS asks the person to allow it once.Both halves of the download ship: the agent bundle carries the tunnel, and the Catalyst app is what a person opens.
Testing
The packaging was proven on a throwaway macOS 26.6.1 machine before any of it was written, because two unknowns could have killed the design. A minimal packet tunnel built as a real system extension, signed Developer ID with these same profiles and installed to
/Applications, reached[activated enabled]; its datagram arrived at a listener on127.0.0.1:51821from the root extension, proving the relay dial survives the move; and a profile pointingproviderBundleIdentifierat the system-extension id reached connected. The approval prompt was answered without a human at the machine, and that method is now indocs/machine.md.Two packaging rules came out of that machine rather than from documentation:
sysextdrejects a bundle with noNSSystemExtensionUsageDescription, and NetworkExtension rejectsNEMachServiceNameunless an app group prefixes it.Owed: the signed dry run on this pull request reaching Notarize. A local build cannot stand in, because the local signing configuration resolves automatic provisioning and never reaches the manual path the release uses.
