DimensionalConsistency.lean — Formal Admission of Dimensional Fitting
The BraidCore framework claims that the Menger sponge void fraction z = 7/27
and the dislocation correction 133/137 are "derived" from geometric
construction. However, when these dimensionless ratios are used to predict
physical quantities with dimensions (years, meters, inverse meters), a
dimensional scale factor P0 must be introduced.
P0 = 1 year is NOT derived from the Menger sponge construction. It is a
fitted parameter chosen so that P(5) = 3⁵ × 7/27 × 133/137 × P0 ≈ 61.2 years
matches the observed sardine cycle period.
This module formally admits the dimensional inconsistency and catalogs
which predictions require dimensional fitting.

/-- P0 is the dimensional scale factor required to turn the dimensionless
Menger period formula P(k) = 3^k × z × 133/137 into a prediction with
units of time.
CLAIMED in framework: P0 = 1 year is "natural" or "derived".
HONEST: P0 = 1 year was chosen AFTER the sardine cycle was observed
at ~61 years, so that P(5) = 243 × 931/3699 × 1 yr ≈ 61.2 yr.
If P0 = 1 second had been chosen, P(5) ≈ 61.2 seconds (nonsense).
If P0 = 1 millennium had been chosen, P(5) ≈ 61,200 years (nonsense).
The value P0 = 1 year is empirically fitted, not structurally derived.
This is the most severe dimensional inconsistency in the framework. -/

-- §5 Honest Assessment
-- ═══════════════════════════════════════════════════════════════════════════
/- Dimensional consistency assessment:
Of the 10 active pre-registered predictions, ALL 10 are dimensionless:
P1 (quantum defect), P2 (wall fraction), P3 (percolation threshold),
P5 (Mott criterion), P6 (amplification limit), P7 (species-area exponent),
P8 (void fraction), P9 (filling factor), P10 (fractional deviation),
P11 (period ratio = 3, dimensionless replacement for withdrawn P4).
P4 (ecological period = 61.2 years) was WITHDRAWN on 2026-05-22 because
it required P0 = 1 year, a fitted dimensional scale factor. The Menger
sponge has no intrinsic timescale. P0 was chosen to match the observed
sardine cycle period.
The FIX: P11 replaces P4 with a genuinely dimensionless prediction:
P(k+1)/P(k) = 3. This ratio is purely structural (comes from the 3-fold
self-similarity of the Menger sponge) and requires no external scale factor.
The adversarial assessment of the ORIGINAL framework: severe structural
weakness. A theory that predicts dimensionless ratios cannot, without an
external scale factor, predict dimensional quantities. The claim that P(5)
was "derived from Menger geometry" was false — the dimensional part was fitted.
Honest framing after fix: 10/10 active predictions are dimensionless and
internally consistent. The withdrawn prediction (P4) is explicitly reported
with its replacement (P11). No active prediction requires a fitted
dimensional scale factor. -/
