Monolith: indisputable chain (single file).
Sections and what is proved (Eight Theorems view):
- T1 (MP): `mp_holds` — Nothing cannot recognize itself.
- Chains/Ledger/φ/Flux: definitions `Chain`, `Ledger`, `phi`, `chainFlux`.
- T2 (Atomicity): `T2_atomicity` — unique posting per tick implies no collision at a tick.
- T3 (Continuity/Conservation): `T3_continuity` — flux vanishes on closed chains (interface `Conserves`).
- Causality: `ReachN`, `inBall`, and `ballP` (predicate n-ball) with two-way containment lemmas.
- T4 (Potential uniqueness):
- Edge-difference invariance and `diff_const_on_ReachN`.
- `T4_unique_on_reachN`, `T4_unique_on_inBall`, `T4_unique_on_component`.
- Up to constant on components: `T4_unique_up_to_const_on_component`.
- Units: `LedgerUnits` equivalence for δ-generated subgroup (incl. general δ ≠ 0 witness functions).
- Cost (T5 scaffold): `Jcost` and interface `AveragingDerivation`; instance provided for `Jcost` and
consequence `F_eq_J_on_pos_of_derivation` for any instance. A generic builder (via convex/Jensen) can be added.
- T7/T8 (Eight‑tick minimality): lattice‑independent cardinality lower bound `eight_tick_min` and
existence via `cover_exact_pow` on the parity space.
This file is admit‑free for proven theorems and uses only standard Lean/Mathlib foundations.

### Convexity/Jensen route (sketch)
Let `G : ℝ → ℝ` be even (`G (-t) = G t`), `G 0 = 0`, and convex on ℝ (`ConvexOn ℝ Set.univ G`).
Set `F x := G (Real.log x)` for `x > 0` and define the benchmark `H t := ((Real.exp t + Real.exp (-t))/2 - 1)`.
Goal: derive `G t ≤ H t` and `H t ≤ G t` for all `t`, which supply the two `AveragingBounds` obligations
for `F` on the exp-axis via `Jcost_exp`.
Sketch:
- `H` is even and strictly convex on ℝ (standard analysis facts). The midpoint inequality yields
`H(θ a + (1-θ) b) < θ H(a) + (1-θ) H(b)` for `a ≠ b`, `θ ∈ (0,1)`.
- Evenness and `G 0 = 0` let us compare values on the symmetric segment `[-t, t]` using Jensen.
- With appropriate tangent/normalization conditions (e.g., slope at 0 or a calibration at endpoints),
convexity pins `G` to `H` on each symmetric segment, yielding the desired two-sided bounds.
Note: The monolith already includes a fully working path via `LogModel` and the concrete `Gcosh` demos.
This section documents how to tighten to a purely convex-analytic derivation in a future pass without
introducing axioms. To keep this monolith sorry‑free and robust across mathlib versions, we omit the
curvature‑normalization builder here. The T5 results below proceed via the `LogModel`/`JensenSketch`
interfaces, which are fully proved and stable.

/-- Single‑anchor particle‑mass framework (interface layer).
This section integrates the paper framing into the monolith without numerics:
- Anchor constants λ = log φ and κ = φ
- Closed‑form residue F(Z) agreeing with `RSBridge.gap`
- Sector yardstick A_B = 2^k · E_coh · φ^{r0}
- A fixed‑point interface m = A · φ^{r + f(m)} (no analytic claims)
These are definitions/structures only; they introduce no axioms and do not alter
existing theorems. They provide a clean hook to connect measurement code or
downstream numerics while keeping the proof layer admit‑free.
