## Summary Merges v4 into v4-next, resolving the conflict in `getBlockHashMembershipWitness` in `server.ts`. The conflict was between v4-next's simple passthrough to `getWorldState(referenceBlock)` and v4's off-by-one bugfix that uses `getWorldState(BlockNumber(referenceBlockNumber - 1))`. The v4 fix is correct: the Noir circuit checks the archive membership proof against `anchor_block_header.last_archive.root`, which is the archive tree root BEFORE the anchor block was added, so we need the world state at block N-1. Resolution: took the v4 bugfix, adapted to use v4-next's `getWorldState` (protected) instead of v4's `#getWorldState` (private). Replaces #21493 which had stale conflict markers.

## Summary Merges latest `v4` (`bb3ea6f1`) into `v4-next` with a proper **merge commit** to preserve the merge topology. This fixes the issue where PR #21702 was squash-merged, causing git to lose track of which v4 commits were already in v4-next. ## Commits 1. **Merge commit with conflict markers** — raw `git merge origin/v4` showing the conflicts 2. **Fix server.ts** — resolve `getWorldState` vs `#getWorldState` conflict (use protected version), remove duplicate `resolveBlockNumber` method 3. **Fix deploy_network.sh** — resolve pre-existing conflict from old merge (keep default multiplier of 2) ## Important **This PR must be merged with a merge commit (not squashed)** to preserve the v4→v4-next merge topology. Add the `ci-no-squash` label. Without the merge commit, future auto-merges will re-encounter the same conflicts.

Summary
Backport of #21639 to v4-next.
Splits
compute_note_hash_and_nullifierinto separatecompute_note_hashandcompute_note_nullifierfunctions to reduce hashing overhead. The old combined function is kept as a deprecated wrapper.Conflict Resolution
Cherry-pick had conflicts in 8 files due to v4-next not having
CustomMessageHandler/process_custom_message(which exists onnext). AllCustomMessageHandlerparameters were correctly omitted. Visibility differences (pub(crate)on next vspubon v4-next) were preserved for v4-next.Changes
