External records and comparison manuscripts

The records named 265-01 and 265-02 are attributed to OpenAI, with manuscript edition date 24 September 2026 OpenAI265A,OpenAI265B,OpenAIOverview. The companion page for 265-01 expressly distinguishes that external record from Cheung's programme Companion265.

Cheung's supplied Oai265-A version 1 separates static entropy records, quantum recovery, and radiation histories. The present development preserves that distinction and reproves the finite statements it uses CheungOai265A. It is a development under the requested identifier, not a claim that a new revision has been registered or approved by N. Cheung.

The other Cheung sources are used as comparisons with their supplied scopes retained:

• En02-A/B/C distinguish a task, its complete channel, and its resource ledger CheungEn02A,CheungEn02B,CheungEn02C;

• En07-B/C distinguish complete preservation, accessible recovery, selected entropy, and thermal data CheungEn07B,CheungEn07C;

• Oai265-B separates finite-confidence coverage from physical calibration and reports a procedure-dependent small-sample limitation CheungOai265B;

• XXII-A/B/D/F distinguish an operational relation, a supplied geometry, a conditional implication, and a nonempty physical instantiation CheungXXII;

• Landmark I's destructive readout has its own finite measurement interface, not a many-body ground-state construction CheungI.

No Cheung theorem is inserted as a premise into an external Family 265 proof stage.
