…field The key-wallet pin bump takes key-wallet dashpay#818, which dropped `generated_at` / `used_at` from `#[repr(C)] FFIAddressInfo`. `build_ios.sh` regenerates that crate's cbindgen header into DashSDKFFI.xcframework, so a fresh framework build left AddressPool.swift referencing a member the C struct no longer has: error: value of type 'FFIAddressInfo' has no member 'generated_at' `generatedAt` is kept (public API, no in-repo or observable change) and pinned to the Unix epoch. That is not a substituted value: every key-wallet `AddressInfo` constructor set `generated_at: 0` ("Should use actual timestamp"), so the property has always evaluated to the epoch. Both it and `used` now document the new `AddressState` model, including that a `Reserved` address reports `used == false` and that reservation state is not observable across the C surface. Also settles the persistence round-trip question raised in review. `generated_at` / `used_at` were never serialized — `CoreAddressEntryFFI` has no field for them, and `address_info_from_ffi` was the only producer, from the literals `0` / `Some(0)` — so dropping them is lossless. `Reserved { at }` genuinely has no slot in that schema and would reload as `Available`, but nothing in platform reserves addresses (no caller of `next_receive_address_and_reserve` / `next_unused_and_reserve` in the workspace), so the loss is unreachable today rather than live. The emit path now spells the `Reserved` arm out and warns instead of silently flattening it, the schema field documents the constraint, and a new test pins the behavior so a future reserving caller surfaces as a schema decision. Verified: `cargo check --workspace --all-targets` clean; platform-wallet 513 passed, platform-wallet-ffi 221 passed; rustfmt clean; scoped clippy (the CI invocation) clean. Swift verified by type-checking the whole SwiftDashSDK module under -swift-version 6 -warnings-as-errors against the cbindgen headers regenerated from the new pin — clean, and the pre-fix source reproduces the reviewer's exact error against the same headers.
