Result

The strongest proposition surviving this twelve-pair audit is not that the ancient record tells one transparent story. It is that a record can cross a rupture while its reader, authority, grammar, physical carrier, archive, and clock separate. Recovery then works by joining partial carriers again.

That pattern is visible at very different scales:

• a cuneiform composition can survive in later copies while its original support and first performance are lost;
• a catalog row can preserve modern knowledge of an artifact without proving one independent physical witness;
• a Maya monument can preserve signs after the institution that trained fluent composers has fractured;
• a khipu can preserve knots, arithmetic, and local custody while the wider comparison and authentication network disappears;
• an inscription date range can cross the event it is supposed to classify unless the event, artifact, use, deposition, recovery, edition, and database clocks are separated.

This is strong evidence for ordinary civilizational inheritance through rupture. It leaves found civilization, breakaway continuity, nonhuman intervention, and literal cataclysm-linked departure explicit but unpromoted at F0/K0/N0/B0.

Frozen review frame

Bridge 61 froze 119 active non-self research pairs at commit b369f27. Bridges 62–65 reviewed four disjoint twelve-pair cohorts. Bridge 66 selected a fifth disjoint cohort:

• 12 pairs;
• 24 files;
• 212,415 bytes read by each reviewer;
• two independent full-file readers;
• zero overlap with Bridges 62–65;
• frozen residual after this tranche: 119 - 60 = 59.

The two short output wrappers contribute no independent evidence. They collapse into their canonical inscription-ontology and event-window pairs.

Do not count unlike things as one denominator

CDLI’s current API exposes artifacts, inscriptions, publications, composites, seals, external resources, and other relations through distinct interfaces. That architecture supports typed joins rather than row inflation (CDLI REST API). ORACC likewise distinguishes P-numbered catalog objects from Q-numbered composites organized around documentary rather than physical structure (ORACC project catalogues, ATF composites).

The clocks that must stay separate

1. event or narrated-event clock;
2. initial composition clock;
3. recension or copying clock;
4. artifact manufacture or inscription-execution clock;
5. use and reuse clock;
6. deposition or archive-placement clock;
7. excavation, acquisition, or recovery clock;
8. physical joining and restoration clock;
9. edition, translation, and decipherment clock;
10. digitization, catalog revision, and current-claim clock.

An AD 79 date interval that overlaps the Vesuvius boundary is not automatically post-eruption. A later copy of a king list dates the witness, not every reign it narrates. A modern khipu database date describes catalog custody, not cord manufacture. A modern Maya reading can reactivate an ancient sign without becoming an ancient witness.

Pair dispositions

The cuneiform claim in plain English

The corpus can tell extremely clear histories when a bounded archive, date range, genre, institution, and physical lineage are dense. It cannot yet be compressed into “the clear history of the world.” The reviewed data instead show:

• heavy concentration in a small number of sites and periods;
• strong administrative overrepresentation;
• missing or uneven archive, stratigraphic, genre, and provenience fields;
• compositions copied across multiple physical witnesses;
• fragments, envelopes, joins, casts, editions, and project mirrors;
• recovery and publication bias.

The viral formulation about more than 200,000 tablets from fifteen locations since 1849 remains a useful routing lead, not a supported compound denominator. The Phase-2 matrix is the controlling quantitative result.

Why the Ur III comparison remains sealed

Stage T successfully removes ruler, year, site, window, publication, archive label, source IDs, names, and numbers from the safe text layer. That is a major leakage control. It is not enough to run the terminal comparison.

Before outcomes may be joined, the project still needs:

• physical fragment and join adjudication;
• tablet/envelope and cast/original relations;
• archaeological archive and subarchive roots;
• dossier, formula, scribe, seal, and official networks;
• grouped holdouts that keep related records together;
• external event controls and blind proposition coding.

An exact repeated phrase may be ordinary bureaucracy, a genre formula, or an artifact of masking. The frozen 31.650092-bit gate is a review threshold, not statistical proof.

Two carrier controls

The Open Khipu Repository’s versioned 2.1.0 release added KH0631–KH0702 and describes itself as an expanding archive of archaeological and museum khipu data. Growth in catalog coverage does not create a universal decipherment key (Open Khipu Repository v2.1.0).

Harvard’s Corpus of Maya Hieroglyphic Inscriptions has operated since 1968, published nineteen fascicles, standardized recording, and built a field archive instrumental in decipherment. That is an unusually strong modern recovery carrier, while still being a modern archive rather than an independent ancient witness (Peabody Museum CMHI).

Together the controls show that carrier survival is layered. Objects, syntax, language, genres, readers, authority, and comparison archives can persist on different clocks.

TimeWar synthesis

The important fringe-forward possibility is not lost by enforcing these distinctions. It becomes testable.

• Ordinary transformation (T) asks whether people, practices, objects, archives, or institutions cross the rupture in altered form. Khipu and Maya provide strong positive cases.
• Found civilization (F) asks whether a securely older productive phase and technical ecology underlie later reuse or ownership claims. No reviewed pair closes that chain.
• Breakaway civilization (K) asks whether a bounded population and self-sustaining material/logistical system continue outside ordinary visibility. Restricted custody is not enough.
• Nonhuman intervention (N) requires authenticated nonhuman agency or discriminating technical residue. Undeciphered signs are not enough.
• Literal departure (B) requires a bounded source population, mechanism, positive destination-side trace, identity continuity, and independent replication. Missing readers or destroyed archives are not enough.

This tranche therefore strengthens the TimeWar thesis without laundering mystery into proof: civilizations can disappear as operating systems while remaining present as scattered carriers. The stranger hypotheses remain live at their own gates.

Falsifiers and promotion tests

The carrier-fragmentation model weakens if secure cases show that full competence and institutional reproduction continued without interruption despite the alleged rupture.

The strong found-civilization thesis gains support only if independently dated older manufacture, a prior productive ecology, later reuse, successor non-reproduction, and matched technical residues close on the same object family.

The Ur III content hypothesis gains support only after the sealed comparison survives archive-aware dependency groups, blind coding, external controls, and held-out replication.

Literal departure gains support only from positive transition and destination evidence. Silence, catalog gaps, damaged texts, mortality, or disappeared institutions cannot promote it.

Disposition

Bridge 66 closes this exact twelve-pair proposition tranche. It does not close the expansive goal, the remaining 59-pair frozen review residual, the Ur III outcome experiment, the Vesuvian held-out study, or the broader public-integration queue.
