chore(forge): check compares the recorded git command line - #303
Conversation
A scenario that kept its step name but changed the arguments (or the credential form) used to keep matching its fixture. The command now compares by placeholder identity; selftest proves a changed argument fails; real Gitea 1.22.6 still passes 24/24.

When a git exchange has a departure (for example, the scenario S entries in departures.json), Ctx.push_ex routes it exclusively through apply_override, so this new comparison never executes; that path validates the step name, result, and output but not cmd. Consequently, changing a departed step's refspec, force flag, or credential URL still reports the departure as honoured, so the command comparison should also be applied within the departure path and covered by a corresponding self-test.
Useful? React with 👍 / 👎.

When check targets an HTTPS server, every credentialed Git URL normalizes to https://<creds>@<host>/..., while the committed fixtures recorded over HTTP contain http://<creds>@<host>/...; a server hosted under a URL prefix similarly retains that prefix. Because inserting user-info prevents scrub() from replacing the full base URL with <base>, this exact comparison now rejects otherwise identical runs solely due to deployment-specific base URL components. Normalize the entire credentialed base URL before comparing commands.

Handle a missing cmd on the actual side of the git comparison.
The git branch guards only the expected record. If the actual record lacks cmd, act["cmd"] raises KeyError. This can happen in the offline run.py diff path when one fixture directory has a git exchange without cmd. The traceback stops the diff instead of listing the mismatch. The recording path is not affected, because git() always records cmd.

Checks green on d99b49f; the two Codex P2s (departed git steps skip the command comparison, https vs http credentialed URLs) are checker-completeness items, tracked into the F2b gate work.
Summary
git step: name, ok, refusal lines +git step: command line (placeholders keep shas, hosts and temp dirs by identity)run.py checkstored the recordedcmdof every git step but never compared it; a scenario that kept its step name but changed the arguments still matched its fixture (follow-up from the F0 review, #297). F2b is the first slice where git steps run against sc-forge, so the comparison lands first, on its own.Evidence
