* fix(s3): evaluate conditional reads before opening object bodies
Reuse locked metadata snapshots for conditional GETs and unify HEAD
preconditions and cache headers. Preserve body-cache hooks and validate
encryption metadata and key authorization before returning bodyless errors.

* refactor(s3): unify conditional reads at metadata quorum
Apply scoped metadata conditions to the existing reader pipeline instead
of maintaining parallel prepared-read branches. Preserve quorum checks,
early-stop, coalescing, and cache-hook behavior on condition misses.
Track metadata-only termination through selection and reject body access
or a changed decision. Keep concrete reader futures off request stacks.

* test(s3): strengthen conditional read acceptance evidence
Assert zero shard, decode, cache-fill, and remote-body calls on matching
conditions with live positive controls. Exercise GET and HEAD through
s3s and Hyper with conditional-header and precedence matrices.
Add reproducible paired application-read benchmarks with isolated
metadata controls and strict drift, artifact, and resource gates.

* refactor(s3): remove obsolete conditional comparison helper
Keep ETag comparison tests on the canonical read-condition evaluator,
remove unused date-trait imports, and name the HTTP case type.

* fix(s3): validate full conditional etag fields
Reject adjacent tags and malformed trailing list members before accepting a
match. Keep the existing request-scoped metadata read and authorization order,
while removing redundant validation wrappers and unused benchmark overrides.
Replace simulated phase coverage with real 304/412 cache-fill probes and extend
HTTP/1.1 and HTTP/2 ingress regressions.

* fix(ecstore): cache terminal conditional metadata safely
Preserve quorum-validated conditional metadata when early termination
cancels the remaining fanout. Restrict those entries to terminal GET
readers; body and full-layout consumers still obtain their own metadata.
Serialize cache publication per key so conditional entries cannot replace
complete layouts or renew their TTL. Retain generation fencing and the
final selected-metadata predicate check before any body access.
Cover real four-disk hedging, nonterminal body and range reads, consumer
isolation, generation races, atomic publication and actual cache expiry.

* fix(log-analyzer): align heal writer failure rule with current logs
Match the current structured all-targets failure, retain legacy log support, and reject partial or unrelated failures.
