What this framework is — and is not

What this framework is — and is not

CPT aims to become capable of the laboratory measurements used to support the Standard Model and QED — and to provide equivalence to those numbers. It does not owe SM/QED ontology, and it is not a present replacement certificate.

Recent honesty (lab → public)

• Local hold programme parked

  honesty

  The local one-seat / thin-seat shop is parked, not closed. Public F1 stays OPEN. Hopfion / ACT existence is not H-D hold. Reopen only with a new independent length (L-NEW) or a transmutation named in L — not another field on leftover R.

• One leftover length cannot mint a thin seat

  honesty

  With a single leftover length, scored soliton roots are O(1) in that length. A Compton-class thin tube is a hierarchy (open frontier F2), not a one-scale root. Dilaton, unfrozen g, and Einstein coupling do not mint a second length.

• R_eff is not the electron S³

  honesty

  The Mach length R_eff ~ 3.3×10²⁶ m remains unnamed. It is not the electron’s 3-sphere (Compton / R_eff ~ 10⁻³⁹), not FLRW curvature, and not F2 L_*.

• Quarks are lobe / channel labels

  E meta

  Not free particles and not knot-diagram crossings. G₂ 3⊕3̄ is a flavour-slot column, not a count of sites on one nucleon.

• No 3-quark photograph

  honesty

  Experiment has not counted three quarks on a live proton. Structural lab reading: the T(2,3) proton seat has two internal lobes; the T(3,2) neutron seat has three. That is a discriminator versus QCD’s 3/3 — not a claimed laboratory photograph, and not a licence to add a third proton lobe.

• A factor 2/3 is not one identity

  honesty

  Two lobes over three lobes is 2/3, and T(2,3) has p/q = 2/3. Neither derives the magnetic-moment ratio μ_n/μ_p = −2/3, which remains an SU(6) compatibility formula (magnitudes are inputs).

• Virtual photons are not CPT objects

  honesty

  A real probe is a free train times a seat. May DIS F₂ / r/R = 0.847 is not a free theorem.

• Two leftovers downstairs

  honesty

  One dimensionless coupling (α) and one length. {c, ℏ, ε₀, e} are SI clothes. Hold is not an m_e factory. α = tan β is a reading, not a derivation of 1/137.

• Seven open frontiers

  honesty

  F1–F7 remain the genuine residuals. F1 chip OPEN, local hold programme parked. F2 remaining generator is L-NEW. Paper I/II submit is PARKED process, not F8. A 137-formula, a third proton lobe, or Darwin-as-hold is the wrong book.

• Requirements spine complete; generative theory incomplete

  maturity

  SAP requirements, typed arrows, scorecards, and stop conditions are explicit on the current skeleton. The native action, occupation, hold, formation, hard join, scale ontology, and a discriminating observable remain open.

Two leftovers · seven open frontiers

Seven genuine physics frontiers: one-seat hold, hard bulk–face join, visibility, spin growth-rate, Foot δ/K/L, native heavy membership, and smash-fragment census if asked. Paper I/II submit is PARKED process, not an eighth frontier. α and local m_e are leftovers, not frontiers. Local hold programme parked; F1 chip stays OPEN.

Genuine physics frontiers

• F1One-seat continuum hold

  OPEN

  One-seat packaging. Two-seat laboratory ED (Darwin / boosted Coulomb) does not close it. Local one-seat/thin-seat programme parked; chip stays OPEN.

  Would not count: Maxwell recovery, dual cancel, Schott/Goedecke, Coulomb bunching, a two-body bench test, Hopfion/ACT as hold, or selling the parked local programme as hold closed.

• F2Hard bulk–face E=mc² join

  OPEN

  Independent geometric length a and inertial mass m. Soft P_EMC is glue [M], not the theorem. Remaining generator is L-NEW — not present R_eff, not an extra field on leftover R.

  Would not count: Dual cancel, α-screening, R = r_e/2, present R_eff as L_*, or dilaton / unfrozen g / Einstein as a second-length mint.

• F3Visibility / occupancy

  OPEN

  Which lattice states are seen is a multi-body / sum-class question. Sister of α, not α.

  Would not count: A knot invariant (gcd, writhe) selecting Hopf vs Free, merging this into a derivation of α, or a 2D occupancy rerun as a close.

• F4Spin growth-rate / moment-arm

  OPEN

  The form of the Regge tower is banked. The slope ratio ≈0.744 is not a missing geometric constant.

  Would not count: Shopping another projection equal to 0.744, or treating 0.744 as tan β.

• F5Foot δ and K/L first principles

  OPEN

  One S⁷ residual with two named numbers. Licensed selectors on frozen R-HOPF are exhausted negatively; the residual remains OPEN and Route E μ/τ ratios are a different track.

  Would not count: Two-channel doubling of Foot K/L, treating Route E as a derivation of δ, or selling an S⁷ involution / equator as a first-principles δ theorem.

• F6Native heavy flavour membership

  PARKED

  Which seats and scales match what SM calls charm / bottom / top. Not free c,b,t on e_i.

  Would not count: e_5 = c, a unique CKM matrix, or a six-quark basis as derivation.

• F7Smash-fragment census

  OPEN if asked

  What whole seats exit a break-up. Probe ≠ smash. Not on-shell quarks.

  Would not count: On-shell quarks as smash products, or mixing probe resolution into jet counts.

Open-frontier labels F1–F7 come from the lab shareable note. They are not the forbidden-list IDs F1–F21 (forbidden F1 is “hold closed”; open frontier F1 is “one-seat hold remains open”).

Longer list and how to pitch in: /validation/open-problems. Residual chips stay on /status.
