   If #34855#pullrequestreview-4205518227 applies to 29.x, then I think it applies here too:

   https://github.com/bitcoin/bitcoin/blob/ce45e8c6a6d76995174f963a03e0f93bf4bf68fe/src/node/miner.h#L112-L125

9. multi_index: fix compilation failure with boost >= 1.91

   This effectively reverts a3cb309e7c31853f272bffaa65fb6ab0a7cc4083 from PR #30194.
   
   That PR reduced the multi_index type signatures as recommended upstream, but
   this is no longer supported as of boost 1.91 because it is no longer necessary.
   1.91 drops support for the pre-c++11 work-arounds that bloated the type
   signatures to begin with.
   
   The upstream `BOOST_MULTI_INDEX_ENABLE_MPL_SUPPORT` define is meant to provide
   compatibility with removed features, but it does not work for this case. Using
   `indexed_by` directly when defining the `multi_index` (as opposed to inheriting
   from it) works with all versions, and avoids the use of the back-compat define.
   
   This is a slight regression when building against boost < 1.91 because the
   bloated type signatures are reintroduced in that case, but it's not significant
   enough to go to the trouble of introducing version detection and ifdefs.

11. ci: unconfine seccomp for i686 no IPC

    Docker 29.4.2 blocks `socketcall(2)` in the default seccomp profile:
    https://docs.docker.com/engine/release-notes/29/#2942
    https://github.com/moby/profiles/releases/tag/seccomp%2Fv0.2.2
    https://github.com/moby/moby/pull/52501
    
    That affects the `i686, no IPC` job because it runs 32-bit Linux test binaries inside Docker.
    
    Add Docker's documented `--security-opt seccomp=unconfined` workaround to this job's `CI_CONTAINER_CAP` - the hook `ci/test/02_run_container.py` already appends to `docker run`.
    
    This restores socket availability for the 32-bit test binaries throughout the job:
