+## Implementation Confirmation
+
+- Confirmed: 2026-07-14 KST
+- Implementing Batch: BAT-024 — `docs/batches/bat-024_20260714_manual-ledger-api/`
+- Implementation commit: `b3447f6 feat(api): add owner-scoped manual ledger endpoint`
+- Developer verification: `594 passed, 12 warnings in 37.24s`
+- Independent QC: PASS (`deleg_f2337a39`) — `594 passed, 12 warnings in 37.29s`; focused remediation tests `4 passed`.
+- Lead gate: `confirm-req-implemented` accepted.
+- Release caveat: production DB rollout needs release-gate handling for additive `portfolio_ledger` columns (`source`, `target_ledger_entry_id`, `confirmation_evidence`, `actor_user_id`), preferably Alembic migration/runbook instead of relying only on `ensure_schema()`.
