# acquire_docx_document_lease [MAINTENANCE] 6507e83a — Whole-document cross-process lease for .docx files, the counterpart claim_docx_region never provided (that tool hard-requires a specific element_id). Use this when a session needs to rewrite an ENTIRE document (a bulk restructure, a canonical-merge promotion) and must block out every other writer, not just one element. Blocked by another live session's whole-file lock (claim_file) OR ANY other live session's claim on the file (lease or scoped element) — a whole-document lease requires the document be free of every other session's claims first. Once held, blocks every other session's writes (via check_docx_region_write_conflict, the same gate update_paragraph and the meridian-docs tunnel relay already enforce) and new claim_docx_region attempts on this file until released or expired (same TTL as every other claim in this module). Returns {leased: true, file_path, session_id} on success or {leased: false, reason, message, ...} on conflict — never raises. 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.

Whatever it removes from Meridian is gone. There is no undo for destructive operations. Risk signals: Accepts file system path (file_path) ## Use case AI agents call acquire_docx_document_lease to permanently remove resources in Meridian, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo. ## Recommended policy (PolicyLayer) Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Meridian: ```json { "version": "1", "default": "deny", "hide": [ "acquire_docx_document_lease" ] } ``` ## Other tools on Meridian (234) - `accept_handoff` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/accept-handoff.md - `answer_hitl` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/answer-hitl.md - `batch_mutate` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/batch-mutate.md - `capture_research_finding` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/capture-research-finding.md - `checkpoint` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/checkpoint.md - `claim_docx_region` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/claim-docx-region.md - `claim_file` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/claim-file.md - `claim_sprint_item` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/claim-sprint-item.md - `clear_capability_profile` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/clear-capability-profile.md - `clone_profile_layer` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/clone-profile-layer.md - `delete_custom_hook` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/delete-custom-hook.md - `delete_note` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/delete-note.md - `delete_sprint_item_pointer` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/delete-sprint-item-pointer.md - `delete_watchlist_query` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/delete-watchlist-query.md - `dismiss_hitl` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/dismiss-hitl.md - `fan_out_sprint_items` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/fan-out-sprint-items.md - `idle_until_all_done` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/idle-until-all-done.md - `index_equation` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/index-equation.md - `index_figure` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/index-figure.md - `index_table` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/index-table.md - `ingest_document` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/ingest-document.md - `ingest_document_structure` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/ingest-document-structure.md - `link_figure_caption` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/link-figure-caption.md - `link_flag_to_section` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/link-flag-to-section.md - `link_proposal_lineage` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/link-proposal-lineage.md - `link_table_caption` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/link-table-caption.md - `log_task` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/log-task.md - `purge_ai_log` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/purge-ai-log.md - `receive_messages` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/receive-messages.md - `reconcile_stale_claims` — Destructive — https://policylayer.com/tools/io-github-ajc3xc-meridian/reconcile-stale-claims.md - …and 204 more: https://policylayer.com/tools/io-github-ajc3xc-meridian.md ## For agents This record is a snapshot.
