Adam Moussa a4e59040d6 test(api): concurrency, codec, 409 wire-shape, and audit-atomicity coverage ... - ProposalConcurrencyTests (shared-connection SQLite, two competing writers): stale-token pre-check with embedded currentState, DB-level lost race reloading the winner's values, 422 token codes, version bump on success, bulk-update proposal-token guard, line-item create bumping the aggregate, audit rows never persisted on a lost race. - GlobalExceptionHandlerTests: pin both SHOC 409 envelopes verbatim (guarded { message, currentState } incl. null state; fallback { status, message, code }) and assert shape exclusivity. - RowVersionCodecTests: round-trip, SHOC-style token literal, malformed/wrong-length rejection. - Existing suites threaded with live version tokens (Ver helper); audit assertions moved from LogAsync to Stage. 187 xUnit green (was 166).		2026-07-13 20:48:28 -04:00
