Engine 1 — discrete closure
From the five-slot carrier: the D₅ half-spinor, the family geometry A₃ = ℙ¹∖μ₄, the μ₄ glue to E₈, and the Standard-Model packet — N_fam = 3, Ω_adm = 48, b₁ = 41/10, and the residue matrix R with det 8.
Two axioms, one discrete compiler, the Standard Model.
The entry document for the TFPT 5.1 set. It does not introduce new physics — it is the reading guide. Its purpose is to state what TFPT claims, what it does not claim, how the compiler closure is organized, and where each load-bearing argument is isolated in the document set — every claim graded and resolving to a single machine-checked ledger.
The two axioms {c₃ = 1/(8π), g_car = 5}. Everything else — the gauge group, the constants, the scale grammar — is a consequence.
The compiler closure, the two-engine picture, the dependency DAG, the proof ledger, and the live experimental tests — stated in one place.
No new physics. The load-bearing derivations — the E₈ glue, the SM packet, the masses, the gravity sector — live in the companion documents.
Fails as a guide if it misstates the dependency order, if a status marker disagrees with the ledger, or if a claim is promoted past the grade its companion document carries.
The introduction makes two things explicit: what TFPT does claim at the compiler level, and what it explicitly does not promote past its grade. The split is what makes the falsification surface auditable.
Everything is generated from the seam constant and the five-slot carrier. They are not even independent: both are elementary symmetric polynomials of the single anchor a = (1,1,2), so the inputs collapse to the anchor plus the lone continuous primitive π.
Read from the two axioms, the theory factorises into exactly two engines — a discrete closure from g_car and a boundary dressing from c₃ — and the bootstrap loop that feeds the E₈ closure back to fix the inputs.
Engine 1 — discrete closure
From the five-slot carrier: the D₅ half-spinor, the family geometry A₃ = ℙ¹∖μ₄, the μ₄ glue to E₈, and the Standard-Model packet — N_fam = 3, Ω_adm = 48, b₁ = 41/10, and the residue matrix R with det 8.
Engine 2 — boundary dressing
From the seam constant: the seed u = φ₀, the electromagnetic fixed point α⁻¹, the Einstein normaliser ξ, and the exponential scale grammar 1 : 5 : 10 that gives v_EW, H₀ and Λ. Gravity is this engine's geometry channel.
The bootstrap loop
The E₈ closure feeds back as an internal consistency check: g_car = 5 is forced three ways (rank-fill, Coxeter-match, integer-glue), and the 8 in c₃ equals rank E₈ = h(D₅) = φ(30) — recovered independently. The bootstrap overdetermines the discrete core; only π stays irreducible.
Every layer of the dependency DAG carries its own grade — exact identity, lattice theorem, numerical fixed point, conditional, or open. The single source of truth is the machine-checked status ledger; if the text and the ledger ever disagree, the ledger wins.
The reviewer path is the architecture and the two axioms (Doc 1), the E₈ glue and the α fixed point (Doc 1), the Standard Model (Doc 2), the E₈ audit and bootstrap (Doc 3), and the honest frontier (Doc 4). Appendix H (horizon), the Origin Theory synthesis, and the research contracts sit alongside.

The dependency order of the four core documents is rigid (1 → 2 → 3 → 4). The recommended reading order starts from the introduction and adds the three companions — Appendix H, the Origin Theory synthesis, and the research contracts — without breaking the chain.
The introduction is the entry document of the TFPT 5.1 set. It states the compiler closure, the two-engine picture, the dependency DAG, the proof ledger, and the live experimental tests — with every claim graded and resolving to the ledger.
