# Heavy correctness jobs that compile the whole workspace (full test suite, clippy,
# benches, doc-tests). To keep the push/PR feedback loop fast, these do NOT run on
# every push — the every-push gate (compile + runtime build + try-runtime + security
# + quick-checks) lives in check.yml / quick-checks.yml / security.yml. This heavy
# suite runs nightly and on demand (e.g. before a release). They run on the dedicated
# self-hosted build runners and — for security on this public repo — never on
# pull requests from forks.

  # pallet-revive (PolkaVM smart contracts) is a TESTNET-only feature. Its contract
  # fixtures are compiled by a build script that uses a polkavm `.json` target spec
  # which the polkavm-linker tooling has not yet updated for Rust 1.96's target-spec
  # format. Skip that contract compilation in native CI builds (upstream-provided
