I received my GCMS notes a few days ago, and based on the history items, I was in E-Grant Grant Review Ready after my test was marked completed and before the rest of the items except oath were marked Completed (my status since then is E-Grant Ceremony Ready). I guess that means the rest of your items are ready for review (Physical presence, Language, Prohibitions), when an immigration officer gets around to looking at your file again.
FWIW these are the statuses in my history:
after AOR: e-Grants Inventory
when my file was sent from CPC Sydney to Niagara Falls IRCC: In Transit
when Niagara Falls received my file: Registry
when scheduled for test: E-Grant Test Ready
after test was marked completed: E-Grant Grant Review Ready
after Physical presence, Language, Prohibitions market completed: E-Grant Ceremony Ready
