documentation-cascade-must-not-defer-past-checkpoint
Deferring project memory file rewrites to ‘post-Checkpoint-1 to avoid double-rewrite’ is a Law 3 violation. The stop-hook correctly flagged this: documentation must sync with file writes in the same operation, even if minor refinements remain. Core facts that crystallize mid-session (e.g., internal-platform reframe) do not require Checkpoint approval to document — only uncertain decisions should wait.
