  "limitations": [
    "Clean-room reproduction of the seed's explicitly specified ll-duplicate defect, not an upstream patch or newly discovered bug.",
    "Original SYNTHETIC fixtures only; no real telemetry, player feedback, human review, or production assurance.",
    "One real separate Astra continuation performed the original repair. Private invocation records and identity are withheld; this historical fact cannot be independently reverified from the public projection.",
    "Public historical records are explicitly redacted derivatives, not byte-identical private transcripts or new executions. Original numerical observations and safe input bytes are retained.",
    "Historical commit hashes are informational; checks use included source snapshots and current public-byte hashes, never private Git objects.",
    "The browser plays back captured Python output; the Python utility runs separately through the documented CLI.",
    "Browser visuals were not browser-validated; DOM behavior and static offline references are tested with Node built-ins.",
    "The seed's separate ordering defect was not an unfinished defect here; this is not the full seed release gate.",
    "The maintenance artifact is provided for a consumer; integration into another workstream is not claimed.",
    "No network dependencies, services, native Hive activation, or release authority. Only the coordinating publisher owns remote publication; this projection performs no remote operations."
