What goes in.

Repair is a dissipative optimization - disagreement gradient descent. It is not unitary on the carrier, which fixes where quantum reversibility must come from.

Derived from the executed C/E instruments: positive, local Liouville operator; exact transfer I − H/M; each repair minimizes the pair's quadratic load cost and V = ||x||²/2 decreases by (d² − r)/4.

Several microscopic repair responses remain empirically open; the model specifies how to tell them apart.

N2 (local six-level), N3 (flat endpoint) and N4 (reciprocal load-response) preserve load/record marginals; distinguishing assays defined, physical attachment missing.

Physics is what overlapping observers can consistently agree on. Everything else - geometry, particles, forces - must be reconstructed from that agreement.

OPH starts not from fields or spacetime but from finite observer patches: accessible algebras, states, records, visible overlap restrictions and repair instruments.

The synthesis paper treats this as a candidate specification: an executable observer whose inhabitants should recover the specification from their own records. It is an input, not a derivation.

Formerly called axioms. A1: oriented observer-patch federation on a spherical screen with twelve-port icosahedral carriers; A2: endogenous overlap transport; A3: generalized-entropy / information projection.

Twelve ports in six antipodal pairs are the minimal symmetric way for a closed patch to exchange records with its neighbours; the icosahedral group is the largest finite rotation group acting on them.

Each local carrier has twelve primitive boundary ports on an oriented icosahedral boundary (30 seams, 20 faces); its A5 action decomposes as 1+3+3'+5. This is part of the specification (A1).

Equal splitting is forced only once the quadratic central-readback cost is declared; that cost choice is an exposed premise in the selection ledger.

All twelve ports carry weight one: the unique minimiser of the quadratic readback cost among 1,352,078 integer splittings of 12.

Antipodal pairing is what makes the record exchange reversible; it fixes the six axes that later carry the Z6 centre.

Ports pair into six inverse axes; this pairing is forced in the selection ledger, not chosen.

Records carry orientation; forgetting it loses information that later distinguishes chirality.

The carrier acts by the oriented 60-element rotation group rather than the orientation-forgetting extension.

Holography: the information of a region is carried on its boundary. The celestial sphere of a local observer is that boundary, and its conformal group is exactly Lorentz.

Observers live on a two-dimensional screen of patches whose conformal symmetry Conf+(S2) is the Lorentz group SO+(3,1).

Instead of a Hamiltonian postulated from outside, time evolution is the process of observers reconciling records.

When overlapping patches disagree, a local repair instrument restores consistency; repeated repair is the elementary dynamics of OPH.

A theory of everything built from many papers must fit together exactly; OPH tracks every interface.

Cross-paper typed composition contract checks that results of different papers compose without hidden type mismatches.

The programme separates what is proven from what is conjectured, and makes the boundary machine-checkable.

Finite theorems are formalised in Lean 4 with CI; numerical results carry replayable receipts.

Which order repairs happen in must be fair; the specific scheduler is declared.

Fair-block contraction branch of scheduler is an exposed premise (selection row 9).

Defining facts as records accessible to enough observers is a premise of the consensus layer.

What counts as public is a declared policy (selection row 8).

OPH predicts dimensionless ratios; converting to SI units needs one calibrated scale.

G_SI is imported as a calibration anchor; a source-derived physical clock is required before G can be predicted.

The minimal scalar content is declared, not yet derived.

Declared matter completion with one-generation/one-Higgs witness (selection row 6).

Hadronic corrections are imported until the QCD solver is source-armed.

Delta alpha_had = 0.027609 +- 0.000112 imported from KNT19 compilation.

OPH is a theory of ratios; one unit must be supplied by measurement.

SI anchors are imported; dimensionful constants need a calibrated physical clock.

In OPH, hbar is the unit of record phase, a convention once units are fixed.

Quantum of action used as unit; not separately predicted.
