# C50 — Endpoint atlas for the full 6877 constructions

22 September 2026 · Step 28 of the authorized 30-step Mirror continuation (C23–C52).

The two complete Creation expansions retain their actual paired endpoints:

| Branch | SP Creation | MT Flood | SP companion death | MT Noah | SP Noah |
| --- | --- | --- | --- | --- | --- |
| N02 | 4420t/4419n BC | AD 2458t/2459n | AD 2757t/2758n | AD 3056t/3057n | AD 3706t/3707n |
| N04 | 4418t/4417n BC | AD 2460t/2461n | AD 2759t/2760n | AD 3058t/3059n | AD 3708t/3709n |

Their consecutive widths are **6877, 299, 299, 650**. Creation remains in its fixed SP Normal/G2 field. All later points in this display are canonical reflections of the qualified regular event or person stations. The SP companion death is not a one-year uncertainty attached to the Flood.

The enclosing and extended Mirror intervals are:

| Branch | Path | Left pair | Right pair | Width |
| --- | --- | --- | --- | --- |
| N02 | Creation 13 | 4420t/4419n BC | AD 2458t/2459n | 6877 |
| N02 | intersection 15 | 5288t/5287n BC | AD 2648t/2649n | 7935 |
| N02 | Noah 17 | 5288t/5287n BC | AD 3706t/3707n | 8993 |
| N02 | Shem–Noah 19 | 6346t/6345n BC | AD 3706t/3707n | 10051 |
| N02 | mixed 20 | 5294t/5293n BC | AD 5287t/5288n | 10580 |
| N02 | right 22 | 5294t/5293n BC | AD 6345t/6346n | 11638 |
| N04 | Creation 13 | 4418t/4417n BC | AD 2460t/2461n | 6877 |
| N04 | intersection 15 | 5286t/5285n BC | AD 2650t/2651n | 7935 |
| N04 | Noah 17 | 5286t/5285n BC | AD 3708t/3709n | 8993 |
| N04 | Shem–Noah 19 | 6344t/6343n BC | AD 3708t/3709n | 10051 |
| N04 | mixed 20 | 5296t/5295n BC | AD 5285t/5286n | 10580 |
| N04 | right 22 | 5296t/5295n BC | AD 6343t/6344n | 11638 |
| N01 | joined 24 | 6351t/6350n BC | AD 6346t/6347n | 12696 |

The labels c/u refer to cumulative LXX OFF Flood / native-ON Shem; v is the retained alternate MT Flood, and A is MT cumulative restored-ON Flood. Those profile distinctions remain part of the endpoint identity even when coordinates or widths agree.

The 24-fold row is deliberately shown on N01. It belongs to the same synthesis but does not complete the missing MT Noah station there. N02/N04 supply the full 6877 branches and their associated 19/22 paths; N01 supplies the joined 24-fold chain and a valid simple 13-fold interval.

This atlas is a concrete result of the continuation, with every displayed interval tied to source-qualified endpoints. It is not a list of unconstrained multiples of 529.

**Validation.** 17 exact arithmetic/structural checks passed. The ten frozen dependencies passed hash verification; all three generated outputs replayed byte for byte in isolation, and the original dependencies remained unchanged. This step reads completed certificates and does not execute their campaigns.

**Scope and provenance.** Controlling File_18 and File_09 remain unchanged. Regular Gears apply only to Noah/Shem/Flood; SP person companions only to Noah/Shem. Creation and Conquest fields remain fixed. Native LXX ON, explicitly derived OFF, independent Flood start/close, and paired suffix inversion at January AD 1 remain in force. No civil year zero, upstream Gear transport, primers, Rounded campaign, or localized −33 is introduced. These are new continuation reports, not recovered historical Reports 11–25. Evidence is conditional on the supplied project model, not a proof of literary intention or independent historical dating.

**Source locators.** File_09 §3.1 (paired Mirror); File_18 §§2.1.3, 3.1–3.2, 6B and 6D (qualified regular and cumulative fields); frozen C15 typed graph, C16 domain certificate, and C22 reduced scale/constraint certificates.

**Best next bounded step — High sufficient.** Test whether preserving every displayed family width is enough to preserve the source bindings.
