# Local ARR Web launcher compatibility recovery

## Metadata

- Date: 2026-08-06
- Status: Restored locally; reboot-persistent supervision remains open
- Scope: owner-local `arr2-web-8766` launcher and local Web listener only
- Last verified: 2026-08-06

## Evidence

- No process listened on local ARR ports and `screen -ls` reported no Web session, so the page could not establish a
  connection.
- The Keychain-backed launcher configuration check passed, but its command still supplied `--node-binary` and
  `--artifact-tool-module`. The current `arr_web.run --help` shows neither option, and its argument parser rejects both
  before application startup.
- Removing only those two retired launch arguments and starting one detached `arr2-web-8766` session restored the
  service. Local `/healthz` returned HTTP 200; root redirected to the login page, whose browser console had no warnings
  or errors. At verification, both `127.0.0.1:8766` and the current LAN address `192.168.3.48:8766` returned root
  redirect HTTP 303.

## Boundary

No login, form submission, upload, Finance/object-store/database write, processor run or monthly-worker action was
performed. The detached Screen process is still not reboot-persistent; the existing supervision maintenance item
continues to apply.
