Jump-Off State(s)

Graph Intent

canonical candidate

Scope

• Define canonical symbol model and normalization path.
• Add translation layers for external app compatibility.
• Preserve backward compatibility for existing ticker-only flows.

Acceptance Criteria

• Core intents support richer identifier payload semantics.
• Mapping logic is deterministic and test-covered.
• Existing integrations continue to work during migration.

Decision Gate (Promote/Park)

Promote if interoperability quality and future-proofing improve with acceptable migration burden.
