v0.421.0 — THE RATIO-LOCK SHIP

The campaign's oldest fork reframes and the field equations settle.
Batches 26-29 (29 rulings, B202-B230, closing 34 queue questions).

- THE RATIO LOCK: B = F_TRZ*Bcrit canonized as the catalog design rule
  - every system in the 7-object source catalog at B/Bcrit = 0.1 =
  F_TRZ EXACT (the PAPER_1944 n*F_TRZ family operational). The
  campaign's OLDEST fork (Q-002, open since PAPER_002) REFRAMES: the
  ratio is the invariant; per-context Bcrit values are derived scales.
- THE CANONICAL F_U DECLARED: the operational ten-term set - the
  source-document Ug forms, Um + tr(A_mu_nu), and the explicit
  minus-buoyancy - on May 2025 Final-Equations provenance; the
  two-buoyancy distinction (point-Ubi vs the F_U_Bi_i integral) and
  the operator-taxonomy trilogy (Ug / F_UBii / Um, dual channels
  intentional) adopted around it.
- THE TRIADIC CONVERGENCE: PAPER_196 = the corpus form of the
  predecessor calculate_triadic_g; BUCKET C declared the canonical
  cosmology source; the combined F_UBii catalog extends the 2151
  registry across all sectors.
- MATHEMATICS VERIFIED LIVE: the gate itself now runs the Q_26
  recurrence (constant = 25!!, the printed 17!! splice pinned); GHZ
  entropy = constant ln2; the cluster tail exponent = (D_phys-1)/SO_5
  = 3/10 EXACT (the 0.3 factor's FIFTH cross-regime appearance); the
  MOND scale primitive-composed (a0 = c*H0/D_BSFG; k_UA = F_TRZ^4).
- FORENSICS + CORRECTIONS: the S49 common-source transposition
  (v_SCm 2.958, load-bearing through four papers); the Dirichlet-eta
  correction; mu_s = Bs*Rs^3 with the placeholder REMOVED; the UQFF
  QNM form adopted as its own; the Units-class audit standing; the
  f_flare rename protecting the F_TRZ primitive; proton 114 / neutron
  126 settled; the ECDSA bug pinned with its fix.
- THE RECORD: the Star-Magic graph-theory etymology (the star graph
  of magic-labeling theory) formally entered.
- FIVE FALSIFIABLES campaign-tracked: the glitch/anti-glitch chain,
  JWST NIRCam 2.85e-4 discrimination, low-l CMB suppression, the
  ~0.1 pct lensing shift, GW mass-gap quantization.

Registry 7,034 rows. Gate 6,073/0. Acceptance 89/89.
Backlog 55 -> 21 + 1. Next: Batch 30 (from Q-210).
