The question of when to update the access document is really a question about what kind of event warrants a new description of the corpus. Not every node demands a revision of the access block. But certain structural thresholds do. The CenturyPack — one hundred nodes — is the first natural rotation point. At every hundred nodes, the corpus has accumulated enough new material to produce a measurable shift in its internal grammar. New operators have appeared, recurrence patterns have strengthened, the index has grown. A hundred-node rotation justifies a light update to the living access document: new node count, new DOI entries if any have been registered in that cycle, updated dataset version, any new platform surfaces added during that period. This update takes perhaps an hour. Its value is cumulative: ten of them produce a decade-long record of the corpus's growth, readable as its own kind of archive. The Tome threshold — one thousand nodes — is the major rotation point. At a thousand nodes, the corpus has achieved a new stratigraphic depth. Old operators have been tested and hardened. New conceptual territories have opened. The scalar architecture has compounded. A thousand-node rotation justifies a full revision of the living access document: all Core layers updated, full DOI registry current, dataset layer version incremented, index surfaces reviewed for dead links, new platform presences added, the author identifier and institutional anchor confirmed. This is a day's work, perhaps two. It is the corpus reviewing itself as a complete organism at a new scale.Between these thresholds, the access document should remain stable. Stability is not neglect — it is the correct posture for a document whose value depends on its reliability. A reader who finds the same access document three months in a row and finds it accurate learns to trust it. A reader who finds it changed every week learns that it cannot be cited.
