# AdBid.io

> Governed AI media buying. Every impression is a decision — bounded by budget, policy, and approval.

AdBid.io is a target design (specification v1.0) for advertising systems that bound,
record, and reconcile machine spending. A bid is treated as a conditional promise to
pay, authorized by a signed spend warrant and proven by a durable receipt.

This document is discovery material, not authorization. An agent must still receive an
explicit, scoped credential from the workspace owner.

## Core concepts

- Spend warrant: Ed25519-verifiable authority binding tenant, campaign, channel, ceiling, expiry, and approval lineage.
- Receipt: durable, unique record of every financial side effect.
- BidderSnapshot: immutable signed state consumed by the edge; rollback never reverses settled spend.
- Micro-dollars: integer arithmetic at every financial boundary; double-entry journal.
- Operational states: ADVISORY, DRAFT, AWAITING_APPROVAL, APPROVED, DEPLOYING, LIVE, PAUSED, FAILED, SETTLING, CLOSED.
