 ## API verification and known caller blockers
 
-v0.3.2 preserves Bearer authentication and all-source unified-ledger reads. It records integral-share stock consolidations even when 8-decimal WAC storage creates a harmless recomputation residue: WAC is rounded half-up to 8 decimals, while the authoritative total cost basis remains independently stored and drives replay. The release gate runs the complete portfolio-hub source test suite (including auth success/failure, strategy catalog/data, portfolio and ledger APIs), then verifies the built image's health/OpenAPI surface, exact 31-file migration inventory, isolated PostgreSQL migration twice, readiness at `0031`, persistent-volume restart, non-root/read-only operation, secret canary absence, and graceful SIGTERM. Publication consumes the tested archive without rebuilding it. The changed-scope Ruff gate uses the locked linter and the ACMR Python path selector, compares normalized findings against v0.2.1, v0.3.0, and v0.3.1, and rejects every newly introduced finding.
+v0.3.3 preserves Bearer authentication and all-source unified-ledger reads. Corporate-action quantity/reference-price updates, the complete ledger snapshot (including `total_value_after`), and the audit row execute in one explicit transaction. The guarded `resume_partial` path repairs only a verified quantity-only partial state without raw SQL.

 The strategy catalog API remains additive: strategy responses expose `nick`, admin create/update requests may set it, and portfolio responses expose the current strategy as `strategy_nick`. Existing clients may omit `nick`; supplied values are trimmed and blank-only values are rejected. trex-web v0.2.3 displays `strategy_nick`, but that dependency does not resolve or waive the separate caller blockers below.
