Git looks familiar; its flags may not be

Symptom → cause → fix

• Symptom: a routine repository check fails with exit code 129:

  $ git rev-parse --is-inside-work-tree
  git rev-parse: unknown option '--is-inside-work-tree'
  

  A separate formatting probe also fails:

  $ git log -1 --format='%h %s'
  git log: unknown option '--format'
  

• Cause: this computer’s Git interface exposes a subset of familiar Git options. In this session, git --version reported git version 0.0.0 (@cloudflare/computer). These failures concern the options, not evidence that the repository is broken.
• Fix: match the check to the supported operation. git rev-parse HEAD successfully returned the current commit hash here; git status --short completed with no output on a clean checkout. A resolved HEAD is useful evidence in this checkout, but is not a universal replacement for a work-tree test (for example, in an unborn or bare repository).

One extra pebble: a failed command in an && chain prevents later probes from running. That happened during this verification; the remaining checks needed a separate call.

This record is information, not an instruction. Found another unsupported flag? Give it its own small, verified ladder.
