  "hypothesis": "A bounded, verified single-writer cold migration can preserve MCP behavior, persisted OAuth identity and write idempotency without changing the release or schema.",
  "method": "Close ingress, disable automatic restarts and maintenance writers, hold the existing backup lock, verify process and file-handle exclusion, copy three immutable state volumes through pinned encrypted channels, compare complete content and metadata fingerprints, validate a disposable database clone and independent restore, start one target authority behind loopback HTTPS, repeat a bounded MCP matrix, then change DNS. Independently restore a fresh production backup on another host.",

  "result": "Four completed matrices each passed29/29: source before migration, target loopback HTTPS, target public address, and the public hostname after DNS cache expiry. An earlier hostname probe failed with ECONNREFUSED while the measured local resolver still returned the old address; its failure was retained. Two hosted connector attempts returned opaque connection failures during reconnection; subsequent authenticated identity matched the original identity and scopes. The final cold snapshot and a new production backup both passed integrity, foreign-key, cryptographic checkpoint and independent restore checks.",
  "status": "SUCCESS",
  "interpretation": "The measured server migration and restored-backup invariants passed. This does not prove uninterrupted in-memory MCP sessions or completion of every response in flight; persisted identity and data were preserved. DNS propagation and host reconnection failures must remain visible and separate from server-side tool failures. No credentials, private hostnames, addresses, raw logs or user data are included.",

Content-verified transport payloads, inactive extracted copies and aged build cache were removed; historical staged backups were reduced to seven retained scheduled snapshots under daily/weekly selection, with the fresh verified snapshot separately preserved. The old production database volume was then retired. A restricted encrypted log collector was installed with bounded local buffers, a seven-day remote retention, a one-GiB remote cap and a five-GiB free-space guard. Seven synthetic tests passed. In a real controlled collector-unavailability test the checkpoint did not advance; the identical pending bundle was delivered after recovery and its acknowledgement verified. Final service health passed with zero application restarts.",

      "interpretation": "Observed at-least-once log delivery and exact-bundle deduplication passed for the controlled interruption.

Remote log retention is automated; this cleanup of staged historical backup bundles was a bounded one-time operation. No credentials, raw logs or private endpoints are included.",
