`full_object_plaintext_len` decides whether a body-cache hook hit may serve
bytes in place of the erasure read. It is a fail-closed allow-list: it excludes
every read whose `ReadPlan::build` applies some other transform (ranged/part,
raw/data-movement, restore, encrypted, remote) with an early `return None`,
then returns a `Some(..)` length only for the whole-plaintext cases. A newly
added `ReadPlan` branch that nobody teaches this gate about falls through to
`None` and safely bypasses the cache. Flip it to a deny-list and the same new
branch silently serves bytes in the wrong representation — the backlog#1108 /
#1109 / #1146 class of bug.
The existing unit and e2e tests only cover the branches that exist today. This
adds `scripts/check_body_cache_whitelist.sh`, a structural guard wired into
pre-commit / pre-pr / dev-check and CI, that asserts every exclusion predicate
and a `return None` still precede the first `Some(..)`. Reordering a predicate,
dropping one, moving the positive return ahead of the gate, or renaming/removing
the function all fail; wording, formatting, and adding a new exclusion in the
same gate do not. Mutation-tested against all four regression shapes.
This machine-enforces the structural invariant that backlog#1146 was kept open
to guard by hand.

The ecstore/global-state migrations are done (backlog#815, #939, #1052 all
closed). Review of every migration-era test/gate measure found three things
actually retirable or broken — everything else is a live anti-regression
guard and stays.
Remove:
- scripts/check_metrics_migration_refs.sh — guards a migration that
finished: rustfs_metrics:: has zero hits, the metrics crate no longer
exists, and the script was never wired into CI or make (only reference
was one line in config-model-boundary-adr.md, also removed).
- crates/obs init_metrics_collectors — the "backward-compatible alias kept
during migration" the removed script was guarding. Zero callers; pure
delegate to init_metrics_runtime.
Archive (docs/superpowers/plans/, continuing the 2026-07 convention,
with the standard archived banner):
- startup-timeline.md, scheduler-baseline.md,
profiling-numa-capability-inventory.md,
kms-development-defaults-inventory.md — one-shot snapshots whose only
consumer is the already-archived migration-progress ledger (their
same-dir links there start resolving again after the move); zero script
pins; fed the closed backlog#660/#665 architecture-review ledger.
Fixed the one outbound link (startup-timeline -> readiness-matrix) that
the move would have broken — check_doc_paths.sh deliberately does not
scan plans/, so nothing else would have caught it.
Wire (found orphaned by the same review):
- scripts/check_extension_schema_boundaries.sh guards a live contract
crate but was never invoked anywhere. Add lint-fmt.mak target, include
in pre-commit/pre-pr/dev-check, add ci.yml Quick Checks step (job
already installs ripgrep), sync the CONTRIBUTING.md enumerated list,
and harden the script against a silently-passing rg probe when src/
is missing.
Keep (verified live, documented so the next cleanup pass does not repeat
this analysis):
- scripts/check_architecture_migration_rules.sh — added a header stating
it is a permanent boundary guard, not retirable migration scaffolding;
'migration' in the name is historical.
- check_migration_gate_count.sh + floor, delete-marker e2e proof, all
pinned docs, compat-cleanup-register sync, remaining inventories
(referenced by live docs).
Verification: all 7 guard scripts pass, actionlint clean,
cargo check --workspace (excl e2e) clean, cargo fmt --check clean.
Adversarially reviewed by two independent skeptic passes; their 7
findings (alias left behind, broken outbound link, missing banners,
wrong backlog attribution, CONTRIBUTING drift, rg exit-2 hole, missing
header rationale) are all folded in.
Drop the [target.'cfg(target_os = "linux")'.dependencies] tokio
"io-uring" feature from 6 crates and the rustfs binary. Because
.cargo/config.toml enables --cfg tokio_unstable globally, this feature
switched every Linux build's file I/O onto tokio's io_uring runtime
backend. Restricted Linux environments (Docker default seccomp, gVisor,
proot, old kernels) reject io_uring_setup with EACCES/ENOSYS, which
tokio surfaced as PermissionDenied and RustFS reported as
DiskAccessDenied at startup.
Add scripts/check_no_tokio_io_uring.sh so the feature cannot silently
return: it fails on any tokio dependency line enabling "io-uring", while
still allowing a future application-level io-uring crate dependency.
Wire it into make pre-commit/pre-pr/dev-check and CI.

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)
