# promote_docx_candidate [MAINTENANCE] W1-K — explicitly promote a status='candidate' docx derivative to be THE accepted derivative for its source_path, demoting whatever derivative previously held that role (if any) to status='superseded' in the same call — a real state transition with an audit trail (promoted_at/promoted_by_session_id on the newly-accepted row; superseded_at/superseded_by_derivative_id on the demoted one), mirroring promote_experiment_run's promotion-pattern precedent. Idempotent on an already-accepted derivative (mirrors promote_research_run's idempotency guard): a repeat call on the same derivative_id returns the existing accepted state unchanged (idempotent_retry=true), never a duplicate transition or an error. Rejects with {error} when the derivative's status is 'superseded' — a superseded derivative can never be re-promoted; register a fresh candidate instead. Returns {derivative_id, derivative, superseded_derivative_id, idempotent_retry}. Persistent-state disclosure: on hosted Meridian, supplied text and project/session metadata -- including task log entries, pinned decisions, sprint items, notes, handoff/goal state, and HITL queue items -- are sent to and stored in Meridian's service, in an isolated per-tenant Postgres database (Neon); self-hosted deployments keep the same categories in the configured local SQLite/Postgres database. This data is visible in the dashboard and API, and may resurface in later project context or handoffs. Notes and pinned decisions can be deleted individually; task log entries and sprint items can be deleted via the dashboard/API (not exposed as an agent-facing tool); HITL queue items and handoff state have no per-record delete. Full removal of any of this data is available via project or account deletion, using the documented controls. Do not include secrets.

Every call changes real data in your Meridian environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
