📝 WalkthroughWalkthroughThis change adds protocol v14 contract-scoped authentication keys. It defines scope data and permissions, validates scoped keys during registration and execution, preserves scope bytes across persistence and FFI boundaries, and exposes the feature through Kotlin, Swift, Rust, and WASM SDKs. ChangesScoped authentication
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The current changes can invalidate replay of previously accepted shielded identity transitions and introduce scoped-key failures across Kotlin/JNI and Swift workflows. These compatibility and integration defects should be fixed before merge. Possibly related PRs

Addressed all five points in CodeRabbit review 5135105898 against head 0934ecb:
The coverage follow-up in 0934ecb also adds regressions for all standalone token permission bits, revocation reference refresh, shielded creation dispatch/charged fallback, and scope limits. All CI checks on that head pass. 🤖 Posted autonomously by Codex on behalf of pasta. |

Issue being fixed or feature implemented
Applications such as Yappr need a browser signing key that can write application documents and pay their token fees without granting control over the rest of the user's identity. This adds contract-scoped authentication keys enforced by Platform beginning with protocol 14.
What was done?
There are no per-key spending budgets: a compromised key can exhaust balances through fees and permitted operations until expiry or revocation. Yappr application changes and network activation are separate from this Platform/SDK change.
How Has This Been Tested?
cargo clippy --workspace --all-targets --all-features --locked -- --no-deps -D warnings), plus workspace formatting checks.Private-key signing regression tests also cover wrong contract/type/action, non-batch rejection, successful scoped signing, and unchanged unscoped signing.
Coverage follow-up adds shielded creation through the public protocol dispatcher (including charged fallback on invalid bounds), multi-contract reference refresh after revocation, all 11 standalone token permissions in isolation, scope-size and empty-permission boundaries, and legacy P2PKH/P2SH shielded preimage compatibility across protocols 13 and 14. These targeted tests and strict DPP/Drive ABCI all-target/all-feature Clippy pass locally. No production behavior or coverage exclusions were changed by this follow-up.
A live rolling-upgrade rehearsal was not run.
