ci: Enable experimental kernel stuff in MSan task
Base the task on --preset=dev-mode to ensure maximal coverage and add
the following:
bitcoin-chainstate (experimental) ... ON
libbitcoinkernel (experimental) ..... ON
kernel-test (experimental) .......... ON
The GUI remains disabled explicitly.
What changed, and why it matters
This commit only changes Bitcoin Core's continuous integration (CI) testing configuration. It renames a CI job from 'MSan, depends' to 'MSan' and switches the build to use a 'dev-mode' preset that enables experimental kernel-related components for testing with MemorySanitizer (MSan). There is no change to the actual Bitcoin node or wallet code that users run, and nothing in the commit suggests a security vulnerability or fix.
No security action required. This is a CI/test configuration change. Reviewers may verify that the new MSan job completes successfully and that enabling experimental kernel components does not introduce unrelated CI noise.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies .github/workflows/ci.yml and ci/test/00_setup_env_native_msan.sh. It removes the ‘depends’ label from the MSan CI job and adds –preset=dev-mode plus -DBUILD_GUI=OFF to the BITCOIN_CONFIG used by the MSan CI environment. This enables experimental kernel components (bitcoin-chainstate, libbitcoinkernel, kernel-test) in the MSan build for broader sanitizer coverage. No source code, consensus logic, networking, or cryptographic code is changed.
