Previously the session-end protocol told the AI to update profile.md
if new insights emerged, with no guidance on where. Over many sessions
this caused freeform bold-text entries to accumulate without structure.
Now requires each update to match an existing H2 section in the file,
with explicit rules against creating new top-level sections.
