Internal claim: measurability of the Mu operator family restricted to AEEQuantitativeEllipticSlices, plus the progressive composition variants (raw Mu → composed Mu → a.e. Mu) needed by the Theorems/Mu.lean and Theorems/CanonicalSolutions.lean consumers. Combines AEESliceAssembly/BlockEnergyAverage.lean with the FixedCompetitorEnergyMeasurability chain on the AEE side of the slice predicate.

Consumed by:

If the single-claim summary above grows into three or more distinct claims, split or refactor per the rebuild contract.

Canonical AEE cube-slice measurability of Mu, with the Ch4 canonical operator/generator plumbing supplied internally.

Canonical AEE cube-slice strong measurability of the selected doubled-Mu Hilbert maximizer/minimizer. The proof selects the first dense generator whose block energy is within 1 / (m + 1) of Mu, and then passes to the Hilbert energy-gap limit.

Canonical AEE cube-slice measurability of a fixed block-L² test paired through the Hilbert energy form with the selected canonical doubled-Mu minimizer. This is the source primitive for scalar-response operator-image averages: the proof uses the same dense-generator selection as the minimizer measurability theorem, then passes the fixed continuous bilinear functional to the limit.

Build the ambient HasMeasurableMuFamily U hypothesis from a measurable AEE quantitative-slice cover.

The explicit hLocal hypothesis records that the sampled coefficient field is measurable into the local coefficient-field sigma algebra on U. For the identity map on ambient coefficient fields this is now supplied by the public coefficient-field measurable-space API.

Open finite-volume version of hasMeasurableMuFamily_of_measurable_aeeQuantitativeSlice_sets, with the smooth-probe Hilbert L² measurability supplied internally.

Law-facing a.e. version of the AEE-slice Mu family bridge. This is the form naturally produced by a random law whose fields are only known to be locally uniformly elliptic almost surely.
