C03.1 · Source basis/status

Kind: **CONDITIONAL**. This describes the exposition, not a scientific tier. Basis: sealed Rev32.7_S303 page-preserving extraction and the house-supplied D1259 Registrar extract. Registrar master SHA-256 **as attested by the house**, not computed from an unavailable master: `cab1d95e8b1e6caad72a30cec35e7ff3bc5394cdc65354b2e17b3d65c90c298a`. Extract SHA-256 computed here: `c25eaf2247542f3dbff542607993d1a5058bf596c268679d86a491abba85f467`. No live Registrar was fetched. The supplied records are DRAFTED/in review; `house_tier` is null. The historical report of a numerical certificate is distinguished below from a calculation executed in this return.

All substantive predicates are classified in PRIOR ART. STANDARD is not a programme discovery; PROGRAMME identifies the corpus-specific assertion and does not establish external priority; UNRESOLVED is a genuine identification or proof boundary. These classifications do not alter the literal labels below.

**Premise before result.** The group-closure statement assumes the registered Cartan realization:

> Let p = span(S70 ) ⊂ Sym(56), k = [p, p], e7 = k ⊕ p (Cartan pair, machine-verified).

— Rev32.7, PDF p.29 [Q001].

The programme's boundary is the specifically named slice, not an unspecified hypersurface:

> Writing LJ = Re− ⊕ J+2 for the slice carrying the golden ladder:

— Rev32.7, PDF p.348 [Q002].

The source's transport limitation is equally binding:

> The result identifies the Albert and shell carriers; it does not make the unpointed shell choose the transported unit.
