External docs changelog

Dedicated payout API keys

Docs now separate standard API keys from payout API keys. Standard keys cannot create withdrawals; payout keys can withdraw only within destination policy, token, network, amount, daily, and optional IP policies.

Withdrawal auth clarified

Withdrawal docs now show dashboard step-up or payout-key auth for creation, plus the new policy rejection and high-risk key errors.

Public staging faucet

Developer docs now include a staging faucet guide and the production website can link to `/faucet` while keeping traffic pinned to sandbox infrastructure.

Invoice underpayment tolerance

Docs now cover business-level defaults, per-invoice overrides, tolerance-settled invoices, and shortfall metadata.

Asset-safe invoice settlement

Settlement docs now clarify strict asset matching, internal-transfer exclusion, and why gas top-ups do not count as invoice payments.

Withdrawal orchestration

Payout docs now explain sweep-first execution, retrying states, requested vs payout amount, and `forceSweepAll` cautions.

Real-time operational surfaces

Dashboard-related docs now mention live counters, realtime notifications, and activity summaries where relevant to operators.
