Module behavioral_sequence 

Behavioral sequence guard – enforces tool ordering policies using the session journal.

This guard checks the tool invocation sequence recorded in the session journal against configurable ordering policies:

• Required predecessors: tool X can only run after tool Y has been invoked.
• Forbidden sequences: tool X cannot be invoked immediately after tool Y.
• Max consecutive: limits on how many times the same tool can run in a row.
• Required first tool: the first tool in a session must match a specific name.

The guard fails closed: if the session journal is unavailable, access is denied.
