* ci: move compile-free and prebuilt-binary lanes to hosted runners
Standard GitHub-hosted runners are free for this public repository, while
every sm-standard minute is paid self-hosted capacity. Move the jobs that
never compile (quick checks, typos, scope selection, the required-checks
aggregate, audit, closed-PR cancellation) and the two s3-tests lanes that
only run the prebuilt debug binary to ubuntu-latest, drop the wget install
the custom image needed for typos, and move the upgrade-compatibility
workflow, whose build shape already runs on hosted runners in
e2e-distributed, with renamed cache keys so the hosted and self-hosted
images never share a rust-cache entry. Gate the package summary job on
resolve having run, so development builds stop starting a pod to report a
skipped job.
* docs(ci): document runner billing and placement rules
Record in .github/workflows/README.md which runner labels GitHub bills
(none for this public repository), which ones RustFS pays for, the rule for
when a job may leave ubuntu-latest, the rust-cache single-writer and
same-image constraints, the patterns that have leaked self-hosted minutes,
and a checklist for new or moved jobs. Point to it from .github/AGENTS.md,
docs/testing/ci-gates.md and the ci.yml placement comment so the rule has a
single home.
Add a default-on multi-role adversarial validation policy to the root
AGENTS.md (risk tiers, six reviewer roles, findings protocol, exit
criteria), a shared adversarial-validation skill with repo-specific
attack probes grounded in shipped bugs, seven audit fixes to the root
instruction files, and an actionlint gate for workflow changes.
Agent-instruction and architecture docs had drifted from the code:
- CLAUDE.md: slim to commands + pointers; fix wrong claim that
`make pre-commit` is the full pre-PR gate (that is `make pre-pr`);
drop stale pre-#3929 file paths and merged bug narratives
- AGENTS.md: drop dead `rust-refactor-helper` skill rule and the
hand-maintained (already stale) scoped-AGENTS index; link
architecture docs from Sources of Truth
- .github/AGENTS.md: replace the outdated copied CI command matrix
with a pointer to ci.yml
- crates/AGENTS.md: merge duplicated Testing sections
- ARCHITECTURE.md: resolve the utils->config contradiction (edges are
removed), mark volatile counts as snapshots, fix a bad path
- docs/architecture: add README router; move one-shot plans/trackers
(rebalance-decommission phases, migration-progress ledger, PR
template) to docs/superpowers/plans with archive headers; fix stale
source paths in kept inventories (core/sets.rs, core/pools.rs,
store/mod.rs, startup_* split from #3671)
- docs/operations/tier-ilm-debugging.md: extracted tier debugging
playbook with corrected paths
- scripts/check_doc_paths.sh: new guard failing pre-commit/pre-pr when
instruction/architecture docs reference nonexistent file paths
- .claude/skills: add tier-debug and arch-checks repo skills;
.gitignore now keeps .claude/skills and docs/operations committable
Verification: ./scripts/check_doc_paths.sh,
./scripts/check_architecture_migration_rules.sh (both pass)
