Ratify the Behavior-native OS architecture and ubiquitous language

[LeftTwixWand]

Outcome

Establish one canonical, vendor-neutral architecture and vocabulary for the Behavior-native OS.

Acceptance criteria

• Record Behavior : Neuron as the governing type relationship.
• Define Synapse as the universal typed durable fact substrate with causal lineage.
• Expose typed request/reply methods only as generated facades over correlated request and response Synapses.
• Guarantee durable delivery at least once, with bounded deduplication.
• Preserve FIFO ordering per sender-target pair, not globally.
• Expose uncertainty and reconciliation for external effects and never claim exactly-once execution.
• Define Module as a non-runtime package.
• Define Surface as immutable data.
• Keep Agent distinct from Behavior.
• Remove Application as a runtime concept.
• Reconcile contradictions in CLAUDE.md, REFINED-ARCHITECTURE-AND-NEXT-STEPS.md, and the public README.

Non-goals

• Implementing runtime components or expanding compatibility commitments.
• Introducing a second request transport, global FIFO ordering, or exactly-once external effects.
