US-003 Review: Create sqlite-storage crate skeleton
Commit: 75af69cd24
Reviewer: Claude Opus 4.6
Date: 2026-04-15

=== Acceptance Criteria ===

1. engine/packages/sqlite-storage/Cargo.toml exists with package name sqlite-storage
   PASS - Cargo.toml exists with name = "sqlite-storage" and uses workspace version,
   authors, license, and edition.

2. Crate is added to workspace members in the root Cargo.toml
   PASS - "engine/packages/sqlite-storage" added to workspace members list, sorted
   correctly between service-manager and telemetry.

3. Workspace dependencies added for: tokio, tracing, scc, lz4_flex, parking_lot,
   async-trait, anyhow, bytes, rand, moka
   PASS - All 10 dependencies present in Cargo.toml with .workspace = true. parking_lot
   was also added to root workspace dependencies (0.12). All other deps already existed
   in the workspace.

4. src/lib.rs exists with pub mod declarations for: types, keys, store, ltx, page_index,
   engine, takeover, read, commit, compaction, metrics, test_utils
   PASS - All 12 modules declared as pub mod in lib.rs.

5. src/compaction/mod.rs and src/test_utils/mod.rs exist as module roots
   PASS - Both files created with placeholder comments.

6. cargo check -p sqlite-storage passes (modules can contain placeholder code)
   PASS - PRD marks passes: true. All module files contain placeholder comments only
   (single-line "//!" doc comments), which compiles cleanly.

=== Additional Checks ===

Crate does NOT depend on pegboard-envoy: PASS - No pegboard-envoy dependency.
Crate does NOT depend on universaldb: PASS - No universaldb dependency.
Crate does NOT depend on nats: PASS - No nats dependency.
Crate does NOT depend on any WebSocket crate: PASS - Clean dependency list.

=== Concerns ===

- All module files are trivially empty (just a doc comment). This is expected for a
  skeleton story but means cargo check is a weak signal. Real compilation validation
  will come in subsequent stories.

- The crate follows existing engine crate patterns well: workspace version/authors/license,
  workspace dependencies, and correct placement under engine/packages/.

- No dev-dependencies section yet. Later stories (US-005+) will need test dependencies.
  This is fine for a skeleton.

=== Verdict: PASS ===
