Promotes S3 from MVP stub to functional via aws-sdk-s3. Default builds
unchanged (zero new deps). Feature flag ensures users who don't need
S3 don't pay the ~5MB binary / C-toolchain cost.
Cargo.toml: new [features] s3 = [...] gating 4 optional deps:
aws-sdk-s3 = 1.130.0
aws-config = 1.8.16 (with behavior-version-latest)
tokio = 1.52.1 (current-thread runtime, no multi-threaded bloat)
bytes = 1 (S3 body passthrough)
s3_cloud/ module (4 files, Constructor Pattern):
mod.rs (190 LOC) — S3CloudStore + MemoryStore trait impl
client.rs (81 LOC) — aws-config builder, KEI_STORE_S3_ENDPOINT
override for R2 / Wasabi / MinIO / any S3-compat
keys.rs (60 LOC) — path-traversal guard + DJB2 hash helper
tests.rs (63 LOC) — builder + prefix + key-guard unit tests
Factory routing (factory.rs):
with 's3' feature + bucket URL → S3CloudStore (real network)
without 's3' feature → S3Store stub (existing MVP, preserved)
Security posture:
- Branch-prefix isolation rejects traversal at keys.rs layer
- aws-config default credential chain (env → ~/.aws → IMDS);
no bespoke credential handling
- rustls, not OpenSSL (matches existing crate tree)
Tests: 22 existing + 11 new (4 keys + 3 client + 5 mod + 5 smoke)
cargo test -p kei-store (default features): 9 passed
cargo test -p kei-store --features s3: 22 + 9 + 5 = 36 passed
cargo clippy -p kei-store --features s3: clean
Real stdout verified for all verify criteria. No fabrication.
MANIFEST.toml [primitive.kei-store] deps updated to reflect feature
opt-in model.
