The t3code-cli Debian and RPM package unpacks the CLI release archive under /opt/t3code-cli, links /usr/bin/t3 to it, and writes a one-line package-type marker (deb or rpm) beside the executable. t3 update did not check for that marker. It downloaded a copy into <T3 home>/runtime/versions, could not repoint /usr/bin/t3, and could move the background service to the copy, so the launcher and the service ran different versions. t3 update now reads package-type next to the real path of the running executable and fails with a CliUpdateError before any network or filesystem change. The message names the package manager command to run instead. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

ApprovabilityVerdict: Approved at Macroscope's review found this PR approvable — This is a focused CLI bug fix that prevents package-managed installations from being silently split between system and home-directory versions. The guard is early and well-tested, while markerless archive and npm installations retain their existing update behavior. You can add or adjust custom eligibility rules. Learn more. |

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Do not treat an unreadable marker as an unmanaged install.
Effect.option converts every readFileString failure into None, not only a missing package-type file. If a package installation has an unreadable marker, runUpdate receives undefined and continues with self-update work.
Distinguish a missing marker from other read errors. Fail with CliUpdateError, or classify non-ENOENT failures as "unknown".
Based on learnings: do not collapse persisted-value read errors into normal absence.

When a system package owns
t3(for example/usr/bin/t3 -> /opt/t3code-cli/t3),t3 updatestill downloads a copy into~/.t3/runtime/versions. It cannot repoint/usr/bin/t3, and it can move the background service onto the copy. The command and the service then silently run different versions.t3 updatenow reads a one-linepackage-typefile next to the real executable. If the file saysdeb,rpm, or any other value, the command stops before any network or disk change and prints the right command, for examplesudo apt update && sudo apt upgrade. Archive and npm installs have no marker, so nothing changes for them.This makes a future
t3code-cliDebian and RPM package safe. #13177 does not ship that package yet. Remote self-update needs no change: the service always runs its pinned copy under the T3 home, not the package's executable.Tests:
update.test.tspasses (5 tests). The new tests cover detection fordeb,rpm, unknown, and missing markers, and a refusal that makes no HTTP, process, or service calls.Created with Claude Fable 5.1 in Claude Code.
