Remove ~280 lines of duplicated code across 30 files in 5 areas:
- centered_rect: consolidate 5 identical TUI layout helpers into a
single pub fn in openshell-tui/src/ui/mod.rs
- server test helpers: replace ~100 inline Store::connect() calls
with local test_store() helpers; deduplicate test_server_state()
in grpc/service.rs to use the shared test_support version
- rogue PKI: extract 20-line rogue CA+client cert generation block
(duplicated in two integration tests) into generate_rogue_pki()
in tests/common/mod.rs
- provider tests: replace 8 identical 28-line test modules with a
single macro_rules! test_discovers_env_credential! invocation
- label constants: centralize openshell.ai/ container label keys
in openshell-core::driver_utils; update Docker and Kubernetes
drivers to import from there instead of redefining them locally
Add resource_version-based optimistic concurrency control to the
persistence layer. Every write now requires an explicit WriteCondition
(MustCreate or MatchResourceVersion), enforced at compile time by
gating unconditional put/put_message behind #[cfg(test)].
- Add WriteCondition enum and put_if for conditional writes
- Add update_message_cas for atomic read-modify-write operations
- Add list_messages/list_messages_with_selector helpers that hydrate
resource_version from authoritative DB rows
- Convert all production write paths to CAS-aware methods
- Gate put/put_message behind #[cfg(test)] to prevent non-CAS writes
- Use structured PersistenceError::UniqueViolation matching instead of
string matching for duplicate detection
- Hydrate resource_version from WriteResult directly on creates,
eliminating unnecessary read-after-write round trips
