Between 2026-09-05 and 2026-09-11 this repository served a handover that\nwas `advanced` and six days dead, and every surface that read this model — MCP, the HTTP\nAPI, the Cockpit — presented its `Next Action` as the thing to do (ADR 0052).\n\nThe thresholds are policy and are read, never restated here: a constant in this file\nwould be a second source of truth for a number the policy owns, and a repository whose\npolicy predates the key is reported as `Freshness::Unknown` naming the missing key\nrather than judged against a default nobody declared.\n\nThe five words divide into two groups, and the division is the one a caller acts on:\n`fresh` and `aging` are current and may be presented as the instruction, `stale` and\n`invalid` must be shown as history, and `unknown` is neither — a record nobody can date\nis not thereby an old record, and treating it as one would quietly discard a briefing\nthat is perfectly good. `Freshness::history` is that division, and it is the only\nplace it is decided.\n\n```\nuse majordomus_cli::capability::builtin::continuity::Freshness;\n\n// the two renderings are one value: the serialised word is the word `as_str` gives,\n// so a reader who met `stale` from MCP and from the command line met one fact\nlet stale = serde_json::to_value(Freshness::Stale).unwrap();\nassert_eq!(stale, serde_json::json!(\"stale\"));\nassert_eq!(stale.as_str(), Some(Freshness::Stale.as_str()));\n\n// and the division a caller acts on: absence of a judgement is not a bad judgement\nassert!(Freshness::Stale.history() && Freshness::Invalid.history());\nassert!(!Freshness::Unknown.history(), \"undated is not old\");\nassert!(!Freshness::Fresh.history() && !Freshness::Aging.history());\n```",
