Phase 5 — PASE and commissioning session
Layer: Native MTR
Call chain
Delegate callbacks
| Callback | When | What we do |
|---|---|---|
| commissioningSessionEstablishmentDone | PASE complete | commissionNode(withID:commissioningParams:) with attestation delegate |
| onPairingComplete (legacy path) | Pairing done | Same commissionNode call |
| deviceAttestationCompleted / deviceAttestationFailed | Attestation | continueCommissioningDevice(..., ignoreAttestationFailure: true) |
| onCommissioningComplete / controller(_:commissioningComplete:) | Matter commission done | performPostCommissioningActionsImmediate() |
PASE: Established inside setupCommissioningSession — secure channel to the uncommissioned device before operational cert install.
What could go wrong
QR parse failure → failedToParseQR. PASE / session setup timeout → COMMISSIONING_ERROR + promise reject. Attestation failure is ignored (ignoreAttestationFailure: true) for development builds.
