@nkavian nkavian changed the title IX-832: Investigate Tempo feat(mpp): add the Tempo MPP method Jun 22, 2026
Add the `tempo` MPP method across the SDK:

- @inflowpayai/mpp: tempo charge request/credential schemas and wire types
  (METHOD_TEMPO, TempoChallengeRequest, TempoMethodDetails), exported from the
  public barrel
- @inflowpayai/mpp-seller: tempo() server method — challenge minting, request
  enrichment, and full on-chain stableBinding; settlement delegated to the PSP
- @inflowpayai/mpp-buyer: tempo() client method — REST-forwarded fulfilment,
  cleanup, and cancelApproval

Tempo settles on-chain via pull-mode credentials minted by the InFlow PSP;
fee-payer (sponsored) challenges are not supported. Updates package READMEs and
docs/mpp accordingly.
