🤖 Augment PR Summary

Summary: Enables Quip validator onboarding with session-key ownership proofs.
Changes:

• Detects Quip via the runtime specification name.
• Adds ownership-proof input shared by onboarding and key updates.
• Validates nonempty, byte-aligned hex and binds proofs to stash and keys.
• Clears proofs when keys, stash, or the session API changes.
• Uses the stash account to sign Quip session-key updates.
• Requires atomic utility.batchAll for Quip onboarding.
• Retains legacy signing, empty proofs, and batching fallback elsewhere.

Technical Notes: Adds RPC guidance, conditional relay-chain warnings, and regression tests for proof handling, signers, and onboarding availability.

Could you check the signer/permission mismatch at packages/page-staking/src/Actions/Account/SetSessionKey.tsx:46, since both launch actions still require isOwnController (packages/page-staking/src/Actions/Account/index.tsx:260,341)? With distinct stash/controller accounts on Quip, a stash-only owner cannot open this now-stash-signed operation, while a controller-only owner can queue a transaction they cannot sign.

Severity: medium
