 ### Added
 - Added Nix package outputs for Android with bundled NDK r24, Rust toolchains, Boost, and cmake.
 - Added `Block::check` to perform context-free validation of a block (size, weight, coinbase, transactions, sigops), with optional proof-of-work and merkle-root checks toggled via the `BLOCK_CHECK_BASE` / `_POW` / `_MERKLE` / `_ALL` flags. Returns a `BlockCheckResult` enum carrying the validation state on failure.
-- Implemented `Debug` for `BlockValidationResult`, `BlockValidationStateRef`, `ProcessBlockHeaderresult` and `BlockCheckResult`, enabling inspection via `{:?}` in logs and test output.
+- Implemented `Debug` for `BlockValidationResult`, `BlockValidationStateRef`, `ProcessBlockHeaderResult` and `BlockCheckResult`, enabling inspection via `{:?}` in logs and test output.
 - Added `#[must_use]` to `BlockCheckResult` and `ProcessBlockHeaderResult` to warn when validation results are silently ignored.
 - Added `ScriptPubkeyExt::as_bytes` to return a zero-copy slice into kernel-managed memory. Unlike `to_bytes`, this does not allocate.
 - Added `Transaction::check` for context-free consensus validation of a transaction. Returns `TxCheckResult::Valid` on success or `TxCheckResult::Invalid(TxValidationResult)` on failure.

 ### Changed
 - The `verify` function's `flags` parameter now uses `ScriptVerificationFlags` instead of `u32`, making the type explicit in the public API.
 - `BlockHeader::new` now returns `Err(KernelError::InvalidLength)` when passed a buffer that is not exactly 80 bytes, rather than delegating the check to the underlying library.
-- `ChainstateManager::process_block_header` now returns `Result<ProcessBlockHeaderResult, KernelError>` instead of `ProcessBlockHeaderResult` directly. `Err` indicates an internal failure; `Ok(ProcessBlockHeaderResult::Invalid(state)` indicates the header failed validation.
+- `ChainstateManager::process_block_header` now returns `Result<ProcessBlockHeaderResult, KernelError>` instead of `ProcessBlockHeaderResult` directly. `Err` indicates an internal failure; `Ok(ProcessBlockHeaderResult::Invalid(state))` indicates the header failed validation.
 - `ProcessBlockHeaderResult::Success` and `ProcessBlockHeaderResult::Failed` renamed to `ProcessBlockHeaderResult::Valid` and `ProcessBlockHeaderResult::Invalid` respectively. `Valid` no longer carries a `BlockValidationState`.
 
 ### Fixed
 - `verify` now uses an infallible conversion for the internal `ScriptVerifyStatus`, since an unrecognized status can only indicate a build-time mismatch between the bindings and the vendored `libbitcoinkernel` subtree rather than a runtime condition.
 - `ChainstateManager::get_block_tree_entry` now resolves the requested block instead of returning `None` for every input. It passed the address of the `BlockHash` wrapper to the kernel rather than the block hash handle the wrapper owns, so no lookup ever matched an entry in the block tree.

 - Updated to latest libbitcoinkernel-sys with btck_PrecomputedTransactionData` changes.
 - The `verify` function now takes a `PrecomputedTransactionData` instead of an array of outputs spent by the transaction. The user is now always required to pass this struct to the function. This is done to encourage its use and protect against quadratic hashing costs.
