  ],
  "acceptance": [
    "the homepage leads with one accepted finding about the world rather than a directory of project internals",
    "a reader can reveal the exact accepted edition and span behind every material dossier sentence",
    "raw mention count and independent-lineage count are visibly distinguished and deterministically reproduced",
    "encyclopedia and skeptical views share the accepted source objects while producing a material, explained policy-relative difference",
    "contradictions, qualifiers, unknown dependence, and unresolved defeaters remain visible",
    "the existing self-describing project corpus remains available through Explore and documentation routes",
    "the featured selection is an explicit accepted compiler input rather than detached hand-authored marketing",
    "all public interfaces expose the same dossier, catalog, frontier, policies, compiler, accepted commit, and content digest",
    "make check passes without changing accepted source state",
    "the accepted Pages deployment passes route, canonical URL, mobile, content-type, and manifest read-back"
  ],
  "limitations": [
    "This task does not claim that one dossier validates the full Epistemedia thesis or that the promoted policies are universally correct.",
    "Hosted API/MCP activation, automated capture, scaled seeding, and federation remain separate tasks.",
    "Human-comprehension claims require real-reader evidence rather than synthetic review."
