On macOS, the launchd service started <T3_HOME>/runtime/versions/<version>/t3 __service-launcher. TCC stores a non-bundled executable's grants (Full Disk Access, App Management, Screen Recording, Accessibility) under the launch agent program's path. Every t3 update or t3 service install at a new version therefore wrote a new path into the plist: users had to approve again, and another t3 entry piled up in System Settings. Reproduced on main with a darwin install at 1.2.3 and then 1.2.4. The plist program moves from versions/1.2.3/t3 to versions/1.2.4/t3.
<T3_HOME>/runtime/launcher/ and points ProgramArguments at runtime/launcher/t3 __service-launcher. The launcher still starts serve from runtime/versions/<v>/t3, so only the path TCC sees stays fixed. The directory is a field on the launchd BootServiceManager, so systemd units and the Linux handoff are unchanged.cp -c -pR, which clones on APFS, and falls back to fs.copy. It goes into a per-install staging directory under runtime/.launcher/ fails. A failed swap restores the previous copy.status reports the service as not current when the launcher copy is missing or of another version, so t3 update repairs it. t3 service uninstall removes the copy and any staging leftovers.Fixes pingdotgg/t3code#17225
Triaged via the automated issue flow; GitCafe issue #17225. Two users confirmed the root cause in the issue thread, and one tested this fixed-path launcher shape on macOS 27 in their fork.

No code changes; evidence and verification added below.
Server-only change, so the captures are ordered runtime transcripts of the real BootService layer: real filesystem, real cp and real t3 --version validation, with launchctl/systemctl intercepted and their argv logged. The platform is forced to darwin (or linux for K8). Release rows use the native Linux release runtimes 0.1.1-preview.20261018.3327 (A) and 0.1.3-preview.20261026.3702 (B). A's .install-complete was missing from the source copy, so it was rebuilt in scratch from the binary's own --version. Harness rows use labelled synthetic runtimes with named faults or Deferred barriers.
Environment: Linux x86_64 (fs-14), kernel 6.1.102, Node v24.22.1 (release rows) / v26.12.1 (harness rows), GNU cp 9.4, ext4. Each checkpoint prints the revision SHA, recorded manager argv, plist ProgramArguments (or ExecStart), launcher tree with modes and hashes, sentinels, state, restart marker and status.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — The PR changes macOS launchd installation to maintain a stable copied launcher path and adds atomic replacement and cleanup behavior across service updates. Because this directly affects macOS privacy/TCC grants and production runtime update handling, the change warrants human review.

macOS launchd services now use a stable runtime launcher path. Install stages and publishes the pinned runtime there, and status checks both runtime copies. Linux services continue to use the versioned runtime path. The troubleshooting guidance describes the stable path and the Full Disk Access grant required when an older service moves to it.

Explanation
The title "fix(server): macOS service keeps its privacy grants across updates" matches the main change. The PR keeps the launchd program path fixed at runtime/launcher/t3, so TCC grants (Full Disk Access and others) survive version updates. It uses a conventional commit prefix and names the affected component and the user-visible result. It is specific and does not list files.
Explanation
Issue [#17225] requires stable macOS service executable paths across version updates. launchdManager sets launcherDir to runtime/launcher, and install publishes the pinned runtime there before it writes the service unit. The unit therefore uses one stable t3 path. Staging, rename-based replacement, rollback, cleanup, and current-status checks cover update safety. Tests cover stable paths, copy failure, rollback, interrupted swaps, overlapping installs, executable mode, and uninstall cleanup. Linux systemd behavior remains versioned. The documentation records the permission behavior. No macOS runtime test was run, but this is not required to establish the coding implementation and automated test coverage.
Explanation
The changes remain within issue [#17225]. The service code implements the stable launchd path and safe launcher lifecycle. The tests verify the implementation, including failure and concurrency cases. The documentation explains the resulting Full Disk Access behavior. The diff does not change the separate desktop permission behavior, Linux systemd path, or Linux handoff.
Explanation
The pull request description includes all required sections: Problem, Change, Scope and approval, and Verification. It explains the root cause, implementation, linked issue, approval context, focused tests, evidence, platform limitations, and remaining macOS checks. The description is complete and directly aligned with the pull request objectives.

Republish the launcher when a remote update commits.
#handlePrepared changes activeVersion, but the launcher copy remains unchanged because publishLauncher runs only during install. Since status requires the launcher sentinel to match input.cliVersion, a completed remote update can report current: false until the user runs service install again. Publish the target runtime to the stable launcher path during remote-update commit.

Not changing this here. On main, a committed remote update already leaves status not current: the plist names versions/<old>/t3, which never matches the plan rendered for the new version. The next t3 update or t3 service install refreshes the unit, and now the launcher copy too. Republishing from inside the running launcher would mean the launcher replacing its own image mid-run, which is outside this fix's scope.
@juliusmarminge Understood. The existing plist comparison already leaves status.current false after a remote update. The launcher sentinel check preserves that behavior rather than introducing a new regression. My request to republish during remote-update commit was outside this PR’s scope, so I withdraw it.
Would you like a follow-up issue for the existing remote-update status behavior?

Independent macOS verification of 7a90b56c54 (macOS 26.7.2, Apple Silicon, APFS, Node 26.8.2).
Tests: bootService, cli/update, cli/uninstall, pinnedRuntime, serviceLauncher and serviceLauncherClient pass at head, 74 passed, 1 Linux-only skip.
Merge with main (12ec17ce4c): one conflict in bootService.ts, three mechanical hunks (xdgConfigHome/systemdUnitDir args from #29244, runtimePaths moved by #23239). Resolved diff against main equals this PR. Same tests on the merged tree: 96 passed, 2 platform skips. vp run --filter t3 typecheck passes.
M03: cp -c -pR of a real 336 MiB 0.1.7 nightly runtime used 4.7 MiB of free space (APFS clone). Tree identical, mode 755 kept, codesign -v --strict passes, the copied t3 --version runs.
M02 (partial): a running signed binary survives the stage, rename, rename, delete swap. The runtime is Developer ID signed (team ARK85ZXQ4Z), so its designated requirement is the same across versions.
Real service path, on a second Mac: I ran the same layout as a local bridge (copy versions/0.1.7-nightly.20261103.4119/ to runtime/launcher/, point the plist's first argument there) and restarted with t3 service restart. launchd then ran runtime/launcher/t3 __service-launcher, its child was runtime/versions/0.1.7-nightly.20261103.4119/t3 serve, and the server answered HTTP 200. So 0.1.7 already accepts __service-launcher from outside versions/.
Not run: the TCC grant check across an update, because that needs a System Settings approval.
Notes, none blocking:
cp is resolved through PATH (bootService.ts:620). With GNU coreutils first in PATH, -c is rejected and every install makes a full copy. /bin/cp on darwin would avoid that.status does flag it.cp -c (bootService.test.ts:111), so the clone branch that macOS takes is not covered by the suite.plutil -replace ProgramArguments.0 inserts rather than replaces. Not an issue for this PR, which renders the whole plist, but worth knowing for anyone bridging locally.
