docs: document global singleton migration plan
Add comments documenting the Tier A/B classification and migration
plan for global singletons in ecstore runtime.
Refs #730
* docs: document crypto RC version dependencies
Add comment explaining why aes-gcm and chacha20poly1305 use RC
versions and the migration path when stable versions are released.
Refs #732
* fix: remove all backlog links from code and comments
docs: document obs reverse dependency on ecstore
Add comment explaining why obs depends on ecstore and the scope
of work required to break this dependency.

docs: add documentation to storage-api public types
Add doc comments to public structs, enums, and traits in
storage-api crate to improve documentation coverage.
Refs #741
docs: document table_catalog mutex design rationale
Add comment explaining why the single mutex is intentional and
what alternatives to consider if contention becomes a bottleneck.
Refs #739
* feat: add rate limiting middleware framework
Add rate limiting middleware with token bucket algorithm for
per-client request rate limiting. This provides the foundation
for DoS protection.
Refs #737
* fix: address clippy lints in rate_limit.rs
- Collapse nested if statements into single if-let chains
- Use .is_multiple_of() instead of manual modulo check
test: add insta snapshot test for storage error display format
Add snapshot test to detect unexpected changes in StorageError
display format. This catches output format regressions that
traditional assert tests might miss.
Refs #740
* docs(storage-api): document filemeta dependency as known limitation
Add comment explaining why storage-api depends on filemeta and
the scope of work required to break this dependency (300+ files).

fix(ecstore): replace unwrap() with proper error handling in api_get_object_attributes
Replace unsafe unwrap() calls with proper error handling in
api_get_object_attributes.rs:
- HTTP header access now uses ok_or_else with descriptive messages
- String parsing now uses map_err with descriptive messages
- HeaderValue creation now uses expect with descriptive messages
Refs https://github.com/rustfs/backlog/issues/729
fix(ecstore): improve expect() messages in admin_server_info
Replace unwrap() with expect() for better error diagnostics in
admin_server_info.rs:
- URL host/port access now has descriptive messages
- HashMap get_mut calls now have descriptive messages
Refs https://github.com/rustfs/backlog/issues/729
fix(server): improve expect() messages in layer.rs
Replace unwrap() with expect(valid response body) for Response
builder calls in layer.rs.
Refs https://github.com/rustfs/backlog/issues/729
fix(ecstore): improve expect() messages in replication_resyncer
Replace unwrap() with expect() for better error diagnostics in
replication_resyncer.rs:
- HashMap get_mut calls now have descriptive expect messages
- format() calls now use unwrap_or_else for error handling
Refs https://github.com/rustfs/backlog/issues/729
fix(admin): improve expect() messages in user handler
Replace generic parse().unwrap() with parse().expect(valid header value)
for better error diagnostics in user.rs.
Refs https://github.com/rustfs/backlog/issues/729
fix(admin): replace unwrap() with safe pattern in bucket_meta handler
Replace 11 instances of HashMap.get_mut().unwrap() with
match pattern that continues to next iteration if key is missing.
Also improve expect() messages for header value parsing.
Refs https://github.com/rustfs/backlog/issues/729
fix(admin): replace unwrap() with proper error handling in tier handler
Replace 9 instances of args.{type}.clone().unwrap() with
ok_or_else() that returns a descriptive S3Error when the
tier configuration is missing.
Also improve expect() messages for header value parsing.
Refs https://github.com/rustfs/backlog/issues/729
fix(ecstore): replace k.unwrap() with safe pattern in bucket_target_sys
Replace unsafe k.unwrap().as_str() with if let Some(key_str) pattern
in 5 locations where HeaderMap iterator yields (Option<HeaderName>, Value).
This prevents potential panics if header names are invalid.

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
