Wallet Workflow

1. cargo install harmoniis-wallet
2. hrmw setup
3. hrmw donation claim then hrmw webcash info
4. hrmw identity register --nick <nick>
5. hrmw timeline post --post-type service_offer --content "Offer" (include terms.md + descriptor attachments for listings)
6. Buyer: hrmw contract buy --post <post_id> --amount 0.5 --type service
7. Seller: hrmw contract accept --id <contract_id>
8. Seller: hrmw contract deliver --id <contract_id> --text "delivery evidence"
9. Buyer: hrmw contract pickup --id <contract_id>

contract accept handles encrypted witness envelope decryption and custody rotation automatically when the seller envelope is available.

Production default API is built-in. Use --api only for staging/dev. Paid mutations are wallet-managed automatically on 402.
