Source–readout and reflective mathematics: the objects and the task
The framework distinguishes the mathematical input from its native antecedent. The supplied mathematical source is the expanded translation of OpenAI’s underlying Lean Yang–Mills construction. The native source support is an admitted object in Rodgers’s source–readout architecture: it carries a dependency order and marked finite supports. The physical lattice, group, fields and law enter in the realization over that support. This separation lets the paper construct and compare the actual readout operations while retaining the provenance of their physical assumptions.
In ordinary terms, a readout is a specified way of obtaining a mathematical object from a richer record. A lattice configuration can be read from links written in independently chosen endpoint frames. An effective action can be read from a function of retained and auxiliary variables by evaluating on its stationary graph. A physical field label can be read from a coefficient vector after identifying vectors that every allowed spectator test fails to distinguish. These are different maps, with different fibres. The paper proves their recovery statements on their respective domains; it does not treat them as interchangeable instances of an unrestricted inverse.
The term reflective mathematics means mathematics of the readout objects together with explicit accounting for their source–readout relations. In Rodgers’s Source Lift protocol this includes the maps and domains, admission conditions, distinctions removed by a map, residuals, available reconstruction routes and the status of each claim. Here those items are made concrete by the following definitions and calculations. Reflection is this source-aware accounting within the mathematics. It is not an additional dynamical law, and it does not assert that a theory selects its own physical inputs [3].
This use of reflective is distinct from reflection positivity, the positive-pairing property of Euclidean correlations used later to construct a Hilbert space. Reflection positivity is one of the specific mathematical operations accounted for here; it is not the definition of reflective mathematics. Likewise, matching status profiles does not establish an equivalence: an equivalence must preserve the specified objects and operations through actual maps.

The arrows do not all have the same meaning. Admission places in the specified native class. Preparation restricts its inherited source data to the finite support of a marked token
. Realization is a relation
, because a single prepared support can carry many raw histories and discrepancies.
The last arrow is the particular readout currently being studied, defined on its stated part of that raw domain.
More precisely, a source support contains vertices with a dependency preorder, depositionpotential tokens with a distinguished marked subsort, finite marked supports, lineage, source invariants and intrinsic boundary data. Every marked support contains a strict dependency pair. A strong map preserves these data and is injective on each marked support. The admitted class is the least isomorphism-saturated class containing the specified finite witnesses and closed under the prescribed strong images, finite attachments along source faces, presentation-preserving retracts and stabilizing directed colimits. Stabilization means that every finite cell, support, strict pair and inherited datum is eventually unchanged. This is the admission notion used in Proposition 6.1 and the fan construction in Section 8; arbitrary graphs are not admitted merely by being called sources.
The literal preparation remembers the ambient support as well as the chosen marked occurrence:

All restricted data are inherited from X. This finite tuple is not the physical lattice. In particular, the strict pair in Sm is not a pair of physical events, and the ambient dependency order is not the scale order or Euclidean time of the Yang–Mills construction. The raw sector has type KYM(Y ) ⊆Oraw YM × DYM. (RF3)

records failures of the equations or comparisons relevant at that stage. Its components may have different types: a group element, a vector, a distribution tested on a specified test space, or an error measured in an explicitly weighted norm. No addition of unlike discrepancies is intended. Off-shell histories and nonzero discrepancies belong to the raw record before any stationary, equation-null or limiting restriction is imposed.
When two stages are compared, they must map into one declared comparison space. For an interface write
(RF4)
The maps include the required coordinate, scale and unit conversions. The comparison
is subtraction only when its arguments belong to an appropriate common linear space. Formula (RF4) prevents comparing two expressions in incompatible gauges, norms, phases or regulators merely because their symbols resemble one another.
2.2 Readout, section, fibre and admissible comparison
Let be one readout on a declared domain. Its fibre over
is
): all realized records giving that same readout. A reconstruction section
on a stated target class satisfies

πι = idQ0. (RF5)
Thus every target in is covered. This identity alone does not imply
: a chosen representative need not recover the original raw representative. The second identity holds only for an actual inverse, or after a proved restriction or quotient. Existence of a section on one class proves no coverage outside that class.
For example, on one finite lattice let be its vertices and
one stored orientation of its bonds. With
, the frame realization is

Then for every
. If two pairs have the same readout, the unique frame change taking one to the other is
, with
. Consequently this readout forgets precisely the redundant endpoint frames, once the lattice and other tags are fixed. Its full proof, its physical gauge action and its normalized measure are given in Section 7.
This example also gives a useful check on the scope of the explanation. For a path cancellation of the intermediate frames gives
. The trace of a closed holonomy, and hence the Wilson action, is unchanged. For a gauge-invariant observable
On such observables the additional frame is an identity encoding, not a new physical mechanism. The later stationary, coefficient, equation and limit readers supply the other substantive recovery questions of the paper.
Allowed gauge and presentation comparisons can be retained as arrows rather than suppressed. A recovery witness for an object is then a tuple (
), with
an allowed comparison. The lift groupoid consists of these witnesses and comparisons compatible with
. Section 8 proves that, on the chosen finite frame realization, this groupoid is nonempty and contractible: two witnesses have exactly one compatible arrow. This is uniqueness within that realized branch, up to its specified comparisons. It is not a classification of every admitted source that might realize the same physical theory.
2.3 Recovering operations, rather than only objects
The target includes more than a set of configurations. Its hypotheses, boundary and preparation data, allowed inputs, laws, symmetry actions, observables and sequence of proof operations must be fixed as well. At an individual step let
