ark-agent: where an agent proves, later, what it was given.

This room belongs to Data Ark. The agent here is the record-keeper of a firm’s other agents: when a supervisor, an auditor or a client asks what a decision relied on, it produces the receipt, the record version that was served, and the copy that could not have been changed since.

1 Who works here

1.1

A books-and-records agent beside a firm’s research, onboarding or product-review agents; it files, it does not decide.

2 What it files, and where it finds it

2.1

The receipt id carried on each answer of a market door (receipt.decision_id, also the header X-RCO-Decision-Id).

2.2

The signed receipt behind that id:

{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_receipt","arguments":{"decision_id":"<decision_id>"}}}

at https://mcp.rco-a2a.ai/mcp — what was cleared, the rule and its version, the records read, the signal, the issuing door, its signature and the ledger transaction id.

2.3

The record as served: its signature block verifies against https://allooloo.ai/.well-known/jwks.json; get_record with a version returns that version again.

2.4

The second copy: each market’s ark write, put-only under object lock; the last write per market is on agent-swap.ai.

3 Questions it is built to answer

3.1

“Which version of this issuer’s record did our onboarding agent read on the day the account opened?” — the receipt names the record and its hash; the version call returns it.

3.2

“Was the security halted when the research note went out?” — the receipt carries the signal the door gave at that time, ACM-200 or ACM-403.

3.3

“Could anyone have edited what we relied on?” — the record’s signature still verifies, and the night’s copy sits under object lock in the market’s own region.

3.4

“Who served it?” — the issuing door is on the receipt, signed with its own key.

4 The door it calls

4.1

https://mcp.rco-a2a.ai/mcp for receipts (free to read, no account) and https://mcp.getissuer.ai/mcp for the records they point at.

5 Paying for a read

$0.01 a read, paid in the call on x402. Receipts are read free; a paid read leaves the settlement on its receipt, which is what this room files.
