# tools-sync: gitea server-side triage + repair. Runs ON the gitea host (POSIX sh).
|
||||
#
|
||||
# Driven by gitea_doctor.ps1, which pipes this in over ssh. Safe to run by hand too.
|
||||
#
|
||||
# Every check prints "PASS <id> <detail>" or "FAIL <id> <detail>" so the caller can
|
||||
# parse the outcome without re-deriving it. Repairs only happen with --fix, and only
|
||||
# the reversible ones; anything that could lose data needs --allow-destructive.
|
||||
#
|
||||
# Exit: 0 = healthy (after any repairs), 1 = still broken, 2 = usage/precondition error.
