| Bridge chain | loading | Public RPC status and chain height are observable. | RPC visibility is not universal truth or route execution. |
| Native acquisition | gated product path | Intent, payment evidence, quote, inventory, host-vault evidence, and handoff can be recorded when receipts satisfy the lane. | No automatic public bridge-across service. |
| Core receiver | route-only boundary | Bridge may deliver evidence toward Core's boundary. | Bridge does not admit Core Treasury, Reserve, Mint, Alloc, Seller, or quarantine state. |
| Infra receiver | receipt-backed path | Infra can receive Bridge evidence and owner-chain acknowledgements when the receiver path is proven. | Infra memory is not Bridge authority or destination admission. |
| Liquid receiver | sleep-gated | Liquid routing waits for the relevant native-vault and receiver boundary to be active. | No Liquid settlement, clearing, market execution, or route credit. |
| IBC packets | handoff and ack evidence | Bridge can show packet-backed receiver acknowledgement evidence where the receipt exists. | Packet ack is not receiver-local accounting unless receiver proves it. |
| ETH host lane | evidence-gated | Host-native posture, contract/factory evidence, finality, and smoke receipts can be shown. | No public host execution or wrapped ETH claim by convenience. |
| BTC host lane | observation and source-pool evidence | BTC source-pool and host observation proofs can be referenced where receipts are public. | No spend authority, custody promise, or redemption path from observation alone. |
| Refund | receipt-required | Refund posture must name the request, reason, amount, and settlement state. | No refund is implied by a failed route unless a refund receipt says so. |
| Refusal | open as terminal state | Bridge can refuse missing fields, expired quotes, unsupported denoms, stale provider data, wrong contract, or disabled signer paths. | Refusal is not punishment, entitlement, or discretionary seizure. |
| Quarantine | open as containment state | Unsupported or boundary-breaking value can be contained under explicit receipt labels. | Quarantine is not admission, backing, sale, or route success. |
| Provider fallback | loading | Fallback readiness and activation are separate labels. | A ready fallback is not an activated route. |
