"""v394 -- COXETER.ATOMS.01: the clockwork coherence -- the three Coxeter primes ARE the three
anchor atoms ARE the three number-field facets, and the prime-2 seam is the common dynamical
factor.  A bird's-eye [E] re-reading that ties v390 (the prime facets) to the anchor a=(1,1,2)
and to v319 (the 5x6 translation clock); it also REGISTERS the residual-asymmetry research
question (RES.COXETER.SYMMETRY.01) as a tracked [O].  No new number.

The Coxeter clock 30 = 2*3*5 = h(E8) had its three primes facet-typed in v390.  Seen from the
anchor, those primes are not three coincidences -- they are the three atoms of a=(1,1,2):

    |Z2| = e3(a) = 2,    N_fam = p0(a) = 3,    g_car = e2(a) = 5,    product = 30 = h(E8).

So {atoms} = {Coxeter primes} = {facet fields}: 2->Q(i) (seam), 3->Q(sqrt-3) (family CP),
5->Q(sqrt5) (carrier golden).  And the dynamic rates are {2,3}-arithmetic with prime-2 as the
common factor (the seam involution drives every sector):

  [E] 1. ANCHOR ATOMS = COXETER PRIMES: a=(1,1,2) has e3=2=|Z2|, p0=3=N_fam, e2=5=g_car, and
        2*3*5 = 30 = h(E8); the clock's three primes ARE the anchor's three atoms.
  [E] 2. ATOMS = FACET FIELDS (v390): each atom-prime is the ramified prime of its facet field
        -- 2->Q(i) (disc -4), 3->Q(sqrt-3) (disc -3), 5->Q(sqrt5) (disc 5); {atoms}={primes}={fields}.
  [E] 3. QG SUSCEPTIBILITY IS PURE {2,3}: chi = 1/(1-(2/3)^6) = 729/665 = 3^6/(3^6-2^6), and
        (2/3)^6 = 2^6/3^6 -- both built from the prime-2 and prime-3 sixth powers; exponent
        6 = 2*N_fam.
  [E] 4. PRIME-2 IS THE COMMON DYNAMIC FACTOR: the seam rate 2/3 = |Z2|/N_fam (prime-2/prime-3),
        and the compiler rate (phi+2)/4 = (phi+2)/|mu4| with |mu4| = 4 = 2^2 (prime-2) -- so
        BOTH dynamic rates carry prime-2 (the seam involution), while prime-3 (family) and
        prime-5 (carrier golden) distinguish the two hands.
  [E] 5. THE 5x6 CLOCK (v319): 30 = 5 * 6 = g_car * (2*N_fam) = (static carrier, prime-5) *
        (dynamic, prime-2*prime-3) -- the translation clock, grounded in the prime split.
  [C] 6. THE READING: the prime-2 seam is the universal dynamical engine (present in every rate);
        prime-3 and prime-5 are the two distinguishable attractors (family / carrier).
  [O] 7. OPEN RESEARCH QUESTION (RES.COXETER.SYMMETRY.01): is the prime-2-as-common-factor
        reading FORCED -- i.e. does the seam involution provably appear in EVERY sector's gap,
        with no independent prime-2 attractor -- or is there a residual asymmetry?  A named,
        tracked open question (see tfpt_research_contracts), NOT closed here.

NET TYPING: [E] the exact arithmetic (atoms=primes=fields; chi=3^6/(3^6-2^6); 2/3=|Z2|/N_fam;
4=|mu4|=2^2; 30=5x6); [C] the seam-as-engine reading; [O] the registered symmetry question.
