RebaseJoinErrorWeighted

The error-weighted provider assembly, the outer join

RebaseJoinRegated's script with the general clause's fifth leg read 𝓔-multiplied on both sides (hypothesis and conclusion). The shell lemma le_ofReal_mul_bracket_add_three is blind to the coefficients' shape, so the only change is one more nonnegativity factor at two sites. The proved RebaseJoinRegated is untouched.

The output is the ε-free block with that one leg replaced; the print's own average form is then produced by HarmonicApproximationProvider's fractional-Poincaré split.

Orientation

This module is a conditional A, not a source-node closure. It is The outer join re-cut at the frozen statement (realized in ProviderEpsFree, read for comparison, never imported). Against the (1/2)-gated display the frozen statement moves exactly two literals, both at the statement's own existential C: the hoisted funding line's (1/2) ↦ C⁻¹ s⁴ and the general clause's good-event threshold (1/2) ↦ C⁻¹ s⁴. The interior clause's event stays at (1/2).

Why this is a re-cut and not a composition

hgen is a hypothesis, and both edits touch its own hypotheses: at the frozen text hgen is funded less and gated on a smaller event, i.e. it is a weaker caller obligation than the (1/2)-gated join's. A weaker hypothesis cannot be fed to the (1/2)-gated theorem, so that script is re-run, and the two back-ports appear where the constants are chosen:

• the interior clause (exists_interiorClause_anchorShape, untouched) is funded from the C⁻¹ s⁴ line through clauseEpsilon_le_half;
• the caller's hgen is funded through clauseEpsilon_anti at its own constant;
• the conclusion's C⁻¹ s⁴ event is pushed into hgen's (larger) one by the proved GoodEvents.goodEventAt_mono_ep.

The joint constant is max (max C_gen C_int) 2: the 2 is exactly what makes C⁻¹ s⁴ ≤ 1/2 on the anchor's own range s ≤ 1.

What the module discharges, unconditionally

• the outer join: the two clauses under one existential constant;
• the a.e. layer: the two almost-sure statements intersected;
• the ℝ≥0∞ shell of both clauses;
• the binder weakening n + 3 ≤ m ⟹ n + 2 ≤ m at the interior-instance call;
• the ε-back-ports of both threshold moves.

The caller obligation hgen, in words

On the anchor's own binders, funded at γ|log γ|² ≤ (s/8)^{3/2} c⋆² · C⁻¹ s⁴, and on the good event 𝒢(n+3, z; s/8, C⁻¹ s⁴), almost surely,

  ‖u − v‖_{L²(x+□_n)}
      ≤ C ( s^{-4} 𝓔_{s/8}(z+□_{n+3}) ( ‖u − (u)_{W'}‖_{L²(W')}
                                        + s^{-3/2} 3^n |(∇h)_W| )
          + s^{-7}  σ_n^{-1} 3^{(1+s)n} [g]_{H^s(W')}
          + s^{-6}          3^{(1+s)n} [∇h]_{H^s(W')}
          + s^{-6}          3^n        ‖∇h‖_{L²(W')} ) ,
      W = (z + □_{n+2}) ∩ □_m ,   W' = (z + □_{n+3}) ∩ □_m ,

with every carrier the anchor's own — the two deliberate asymmetries are unchanged: the in-bracket ∇h average stays at W, and the interior clause's slot, gate, flux index and (1/2) event all stay at n+2.

The frozen block, from the proved interior chain and one real-valued caller obligation.

The conclusion is the frozen statement byte-for-byte (only the two indicator binders omega' carry a leading underscore, forced by the repository's zero-warning gate: the frozen file escapes the unusedVariables linter only through its sorry). The hypothesis hgen is a conditional A obligation, not a premise of the pinned source statement.
