* feat(get): SF01 - bucket validation cache
Add 5s TTL cache for bucket validation to avoid repeated stat_volume()
calls on every GET request.
Changes:
- Add BUCKET_VALIDATED_CACHE (OnceLock + RwLock + HashMap)
- Add invalidate_bucket_validation_cache() for cache invalidation
- Add invalidate_all_bucket_validation_cache() for bulk invalidation
- Update get_validated_store() to use cache
- Add cache invalidation in execute_delete_bucket()
Expected impact: 3-5x improvement for small file GET latency.

* feat(get): SF03 - metadata cache TTL increase
Increase metadata cache TTL from 250ms to 2s and capacity from 1024
to 4096 entries.
Changes:
- GET_OBJECT_METADATA_CACHE_TTL: 250ms -> 2s
- GET_OBJECT_METADATA_CACHE_MAX_ENTRIES: 1024 -> 4096
All mutation paths already call invalidate_get_object_metadata_cache,
so the longer TTL is safe.
Expected impact: 10-50x improvement for hot objects.

* feat(get): SF04 - remove unnecessary tokio::spawn in metadata fanout
Replace tokio::spawn with direct async future in read_all_fileinfo_full_wait.
join_all already provides concurrency, so tokio::spawn adds unnecessary
task creation and scheduling overhead.
Changes:
- Remove tokio::spawn from metadata fanout futures
- Update result handling for direct future results
Expected impact: 16-32us reduction per GET request.

* feat(get): SF06 - conditional lifecycle check
Only call resolve_put_object_expiration when the object has an
x-amz-expiration metadata marker. This avoids unnecessary lifecycle
configuration reads on every GET request.
Expected impact: 50-100us reduction per GET request.

* feat(get): SF07 - conditional metrics recording
Gate hot path metrics behind get_stage_metrics_enabled() to reduce
overhead when metrics are not needed.
Changes:
- Conditional record_zero_copy_read
- Conditional manager.record_disk_operation
- Conditional manager.record_access
- Conditional manager.record_transfer
Expected impact: 20-50us reduction per GET request.

* refactor(get): SF01 - use moka instead of dashmap for bucket cache
Replace OnceLock + RwLock + HashMap with moka::sync::Cache for bucket
validation cache. moka provides built-in TTL support and is already
available in the workspace.
Changes:
- Add moka dependency to rustfs crate
- Replace manual TTL management with moka's time_to_live
- Simplify cache operations

* feat(get): SF02 - inline data fast path
Add fast path for small inline objects that bypasses duplex pipe,
tokio::spawn, and bitrot reader creation when data is already in memory.
Changes:
- Add inline data detection before codec streaming gate
- Direct in-memory erasure decode for inline objects <= 128KB
- Add GET_OBJECT_PATH_INLINE_DIRECT metric path
- Skip duplex pipe and background task for inline data
Conditions for fast path:
- Single part object
- Inline data available
- Size <= 128KB
- Not encrypted/compressed/remote
- No range request
Expected impact: 2-3x improvement for small file GET latency.

* feat(get): SF05 skip IO planning + refactor inline detection + adaptive bucket cache
SF05: Skip disk I/O semaphore for inline data fast path
- Reorder prepare_get_object_read_execution: read first, then decide semaphore
- Inline objects skip acquire_disk_read_permit() entirely (saves 100-200us)
- Add is_inline_fast_path field to GetObjectReadSetup
Refactor: Unify inline detection logic
- Add ObjectInfo::is_inline_fast_path_eligible() as single source of truth
- Version-aware thresholds: non-versioned 128KB, versioned 16KB (matches PUT)
- Eliminates divergent conditions between set_disk/mod.rs and object_usecase.rs
Refactor: Restore fault tolerance in metadata fanout
- Restore tokio::spawn + JoinError handling in read_all_fileinfo_full_wait
- Prevents single disk read panic from unwinding the entire operation
Refactor: Restore lifecycle check correctness
- Remove incorrect SF06 conditional that skipped lifecycle for most objects
- Always call resolve_put_object_expiration (original behavior)
Fix: make_bucket cache invalidation
- Invalidate bucket validation cache on create_bucket
Fix: erasure decode written validation
- Check decode() return value; error if 0 bytes written for non-empty object
Adaptive bucket cache
- Default: RwLock<HashMap> for < 100 buckets (low overhead)
- Opt-in: starshard::ShardedHashMap via RUSTFS_BUCKET_CACHE_STARSHARD=1
- 5s TTL with manual timestamp checking
Benchmark results (warp get, concurrency 32, 10s, 3 rounds):
- 10KiB: 25.10 MiB/s (+28.2% vs SF01-07)
- 100KiB: 221.81 MiB/s
- 1MiB: 1972.78 MiB/s
- vs main: -10% to -12% (inline path not triggered by warp)

* fix(versioning): use read lock for versioning config query + five-expert analysis
P0 fix: BucketVersioningSys::get() was using write lock on
GLOBAL_BucketMetadataSys for a pure read operation. This serialized
all concurrent GET requests (3 write-lock acquisitions per request).
Changed to read lock — get_versioning_config() handles its own
internal locking via metadata_map RwLock.
Five-expert analysis identified top bottlenecks:
1. Versioning write lock (P0, fixed)
2. Inline fast path not triggered (P0, needs verification)
3. Metadata fanout no early-stop (P1, early-stop has bug, reverted)
4. Request-level versioning cache (P1, pending)
5. Duplex pipe for small objects (P2, pending)
Benchmark (read-lock fix, warp concurrency 32):
- 1KiB: 2.29 MiB/s (vs 2.53 before, within variance)
- 10KiB: 25.00 MiB/s (same as before)
- 100KiB: 246.72 MiB/s (+11% vs 221.81)
- 1MiB: 2039.95 MiB/s (+3% vs 1972.78)

revert: restore #![allow(dead_code)] - clippy -D warnings treats warn as error
The #742 PR changed #![allow(dead_code)] to #![warn(dead_code)], but
CI runs clippy with -D warnings which turns warnings into errors.
This caused CI failures across multiple PRs.
Reverting to #![allow(dead_code)] until the dead code is actually
cleaned up. The 189 warnings in ecstore should be fixed incrementally
by deleting dead code and adding item-level allows, not by changing
the crate-level policy.
fix(ecstore): replace unbounded metadata cache with moka
Replace the manual Arc<RwLock<HashMap>> metadata cache with
moka::future::Cache, which provides:
- Built-in LRU eviction when max_capacity is reached
- Automatic TTL expiry via time_to_live (250ms)
- Lock-free concurrent reads
- Non-blocking invalidation
Fixes the memory leak risk from unbounded HashMap and the
all-or-nothing eviction logic that cleared all entries at once.
Closes#743
