The 141-row observable ledger
The observable ledger organises every prediction DCT commits to into 11 domains, with row-by-row prediction, measurement, residual, verdict, and source paper. Closure state: 117 HIT / 14 SOFT / 0 FLAG / 0 MISS / 10 OPEN = 141.
This page is the broad inventory. Live row-level numbers are in corpus (master table) and the closure-archive ledger. Per-row index:.

Derivation census (135 tag assignments)
Each row is tagged by how the prediction is derived. Census refined from earlier 82/59 split:
| Derivation tag | Count | Description |
|---|---|---|
| DERIVED_FROM_PRIMITIVES | 42 | Pure icosahedral algebra: master identity, Burnside, spectral sums, mathematical identities (D5), PPN structure, H_phys clock map. No physics input beyond V=12, E=30, F=20, |2I|=120, φ. |
| DERIVED_WITH_ASSERTED_STEP | 34 | Uses standard physics inputs: SM loop running for sin²θ_W(M_Z), slow-roll for n_s, BBN for Ω_bh², RGE for α_S. DCT provides geometric boundary conditions; SM provides the running. |
| POST_HOC_ANSATZ | 25 | Integer combinations of icosahedral invariants matching measured mass ratios (pion, kaon, D, B mesons, charm, bottom, strange masses, quark ratios, top, η_B exponent). Clean numerical matches but no derivation chain from the DCT Lagrangian to these specific combinations. Predictive content: the coefficients, not the masses. |
| ΛCDM_PASSTHROUGH | 18 | Quantities that DCT inherits from ΛCDM at leading order via the conformal-wall theorem (recombination CMB, BBN, BAO photon-null geometry). |

Machine-readable catalogue
Per-observable detail pages live at /observables/<slug>/. Each carries a JSON sidecar at /observables/<slug>/data.json with the prediction, measurement, residual, source paper, and Python verification snippet metadata. Index of all detail pages: /observables/manifest.json (JSON-LD).
Empirical isolators
Not every HIT row is an empirical isolator (a row that uniquely distinguishes DCT from competing frameworks). The classifies rows into four exclusivity tiers:
- POTENTIALLY_EXCLUSIVE — distinguishes DCT from ΛCDM/SM under current measurement bounds. Examples: H_phys = H_E/√P₀ clock-rate mapping; ΔN_eff = 0.027 forward test; M_lens/M_dyn turnover.
- SHARED_VALUE — other frameworks can reproduce. Examples: CKM/PMNS angles (SM free parameters; DCT derives them but SM fits them); particle masses (SM uses Yukawa couplings; DCT derives the Yukawas from geometry).
- STRUCTURAL_THEOREM — closed mathematical identity, not an empirical test. Examples: master identity, Casimir spectral sums.
- ANTI-PREDICTION — any positive detection falsifies DCT. Examples: σ_SI = 0 (WIMP); proton decay null; magnetic monopole null.
