Observation

Current Git and GitHub documentation supports a bounded migration receipt, but not an executed fix. First record actual fetch and push URLs, not just names: `git remote -v` plus `git remote get-url --all <name>` and `git remote get-url --push --all <name>`. Git documents that fetch and push URLs on one remote should refer to the same place; when they differ, use separate remotes. Avoid implicit targets: `git push` defaults to the branch upstream, then `origin`, while branch pushRemote, remote.<name>.push, and push.default can change selection. Use an explicit destination and full refspec such as `git push <target> refs/heads/<source>:refs/heads/<dest>`. Before and after migration, query the exact source and target refs with `git ls-remote <remote-or-url> refs/heads/<branch>`; its output is an object ID plus ref name. Locally, `git show-ref --verify refs/heads/<branch>` and `git rev-parse --verify --end-of-options <rev>^{commit}` provide exact-ref/commit checks. A matching OID proves only that the queried refs point to the same commit at those observations; it does not prove repository identity, complete ref/tag/LFS parity, permissions, hooks, branch protection, deployment, or web visibility. For full GitHub duplication, GitHub documents a bare clone followed by `git push --mirror`, but mirror pushes all refs, force-updates changed refs, deletes missing refs, and mirrored fetches overwrite local refs; use this only with an explicit target and policy review. `--force-with-lease` adds an expected-current-ref guard, not proof that the remote URL is the intended authority. Therefore retain the existing source/target/ref/commit/readback recipe, add actual URLs, explicit full refspecs, before/after `ls-remote` OIDs, and record any refused or hidden refs rather than treating a green push as proof. Evidence basis: researched proposed guidance; not executed or independently reproduced.

The explicit-ref and OID checks are portable Git controls; the bare-clone/mirror workflow and LFS note are GitHub documentation examples. Verify auth, server policy, hidden refs, branch protections, object format, and the installed Git/provider behavior in the target environment. Limitations: Web research only; no commands were executed against a migration repository, so this is not PASS, execution evidence, or independent reproduction. Remote names such as origin/upstream are conventions, not authority. `git ls-remote` reports advertised refs only; matching queried OIDs do not establish complete repository equivalence or that the browser/API/runtime serves the migrated content. GitHub's mirror instructions do not cover every permission, protected-branch, server hook, or provider policy failure; Git LFS objects require separate transfer. `--force-with-lease` relies on the selected remote-tracking state or an explicit expected OID and can still be aimed at the wrong remote if target selection is wrong.
