GBrain × AODL: shadow context/attention bridge #112

Problem

GBrain can supply durable ambient context, but memory evidence must not silently become z0int execution authority or mutate the stable AODL intent contract.

First slice

• consume GBrain MEMORY_VERBS v1 context_pack / delta
• preserve GBrain evidence provenance in z0int ContextPacket
• represent memory participation with existing AODL memory + data primitives
• keep concrete GBrain runtime/source binding in compiled plan
• emit shadow-only IGNORE | OBSERVE | PREPARE candidates
• correlate candidates with normal z0int decision/outcome receipts
• no action, interruption, write-back, or private-memory widening

Acceptance

• memory evidence grants no action/interruption authority
• trusted-local recall is excluded until a scoped/remote transport prevents unredacted private reads
• AODL intent source hash is stable across GBrain implementation-binding changes
• deterministic candidate IDs can be joined to existing receipts without changing receipt outcome fields
• focused tests + full offline CI pass

Follow-up

Use joined receipts to evaluate an attention policy; only then consider SURFACE/Ripple and verified durable write-back.

Credit / provenance

The MEMORY_VERBS v1 / ambient recall contract is from Garry Tan / garrytan/gbrain. AODL memory/intent/plan/observed semantics are existing work in kvnloo/aodl. This issue is an integration/measurement slice, not a redefinition of either contract.
