  # chore: merge master 23.1.5 back into develop

  ## Issue being fixed or feature implemented

  Backmerge current `master` into `develop` so the active development branch
  includes the `v23.1.4` and `v23.1.5` release-line changes.

  ## What was done?

  Merged `upstream/master` (`v23.1.5`, `5dde61050d20c23c3e179c34e663a025f56843f3`)
  into `upstream/develop`.

  Carried forward release metadata and generated artifacts for `v23.1.4` and
  `v23.1.5`, including version metadata, man pages, release notes, checkpoints,
  chainTxData, minimum chain work, assume-valid data, and seed updates.

  Resolved conflicts in Dash-specific code while preserving develop-only refactors:

  - Kept develop's `CChainstateHelper` ownership layout and `SuperblockManager`
    integration.
  - Carried forward the EHF block-connect optimization without reintroducing the
    removed `CMNHFManager` quorum-manager member.
  - Carried forward the LLMQ signing-share inventory bounds into develop's
    `NetSigning` split.
  - Carried forward the Platform node ID mempool conflict handling and its
    functional test coverage.

  ## How Has This Been Tested?

  - Ran `git diff --check upstream/develop...HEAD`.
  - Scanned changed files for conflict markers.
  - Verified the corrected `CMNHFManager` constructor call after conflict
    resolution.
  - Ran the required pre-PR `code-review` gate against the backmerge branch;
    final recommendation was `ship` with no significant issues found.

  No local build was run; this is a release backmerge and CI should run the full
  Dash Core PR build/test matrix.

  ## Breaking Changes

  None expected. This is a backmerge from the release branch into `develop`.
