Agent Compute Ledger

Record a unit of agent compute work. energy_j = power_w * duration_s; carbon_g follows from grid intensity. If bit_ops is declared, the entry is validated against the Landauer floor (bit_ops * kB * T * ln2) — physically impossible claims are rejected. Idempotent on entry_id.

Aggregate footprint for an agent: total J, kWh, gCO2e, cost, and mean Landauer efficiency. Totals are exact sums of the ledger entries.

Issue a content-addressed attestation for a ledger entry (verifiable green-compute / energy claim).

Verify an attestation by recomputing the entry hash.

Verify the tamper-evident hash chain of an agent's ledger.

List all ledger entries for an agent.

Emit an x402-C carbon receipt for a recorded work entry — the physically-grounded {version, g_co2e, energy_j, method, landauer_*, ...} object an x402 machine-payment receipt can carry. method is 'landauer-floor' when the workload declared bit_ops (thermodynamically validated), else '

Record an audited GHG inventory in a separate append-only chain. mass_g is exact integer grams; content and factor-pack digests are bare lowercase SHA-256 hex. Idempotent on inventory_id.

Fetch one immutable inventory record by inventory_id.

List the separate GHG inventory chain for an agent.

Verify an agent's inventory hash chain independently of compute work.
