      "heading": "FINDINGS",
      "content": "On 13 September 2026 the registry was reconciled for the first time against the authoritative federal catalog data file rather than against search and mirror sweeps. Of 180 catalog entries listed since 1 March 2026, 54 were absent. Forty-one predated 1 July, before the registry treated every catalog alert as owed; they were admitted for completeness and labeled not owed under the rules then in force, with 1 July declared as the completeness-era boundary, a reconstruction that will not be moved to reclassify any absence. Thirteen entries listed from 1 July onward were genuine misses, the longest at 92 days, all keyed to their true listing dates."

        "Enumeration without admission",
        "Duplicate on re-catch",
        "Silent no-op edit",
        "Observation without signal (two published observations were founded on entries that existed in the observation layer and never as signal rows)",
        "Matcher defect (bare-number substring matching against note text)",
        "Research-pass undercount (a deep pass is a sweep, not a source)"

    },
    {
      "heading": "MECHANISM CHANGE",
      "content": "Discovery now runs against the catalog data file at every run, by full-form identifier against admission fields; search and mirrors enrich but do not discover. Seven consecutive runs after the change matched the catalog byte-for-byte or admitted at zero to one day's lag."

    {
      "heading": "WHAT THE EVIDENCE ESTABLISHES",
      "content": "The registry's gaps were produced by how its sources were read, not by which sources it read. Forward-window auditing cannot see a missed historical batch; source-to-registry reconciliation can."

  "attestation": "This memorandum records that the registry disclosed its own incompleteness at full volume, dated every absence, and changed the control that produced them."
