Holography Landauer Bridge Walls Clausius Step Heat Is One Channel Posting

The posting rule

The declaration clausius_stepHeat_is_one_channel_posting is a small but exact piece of bookkeeping. It says that in the Recognition Science framework, the heat posted by a single step of a cell configuration is defined as the change in a binary flag: the new value of the flag minus the old value. If the flag turns on, the step posts one unit of heat; if it turns off, it posts negative one unit; if it stays the same, it posts zero. This is a definitional identity, true by how the terms are set up, and it is the atom behind every face of the framework's heat cell.

What the declaration does not do is more interesting. It does not identify this posted flux with any independent calorimetric measurement, any physical thermometer reading, or any SI-unit joule count. The framework keeps those two things apart on purpose. One can define a heat carrier that is literally the scaled posted flux, and the library proves that this tautological choice satisfies the carrier premise by definition. But that is hygiene, not physics. The framework also proves that a zero heat carrier fails the premise as soon as any forced step posts a nonzero flux, so the posting rule is not vacuous. The missing arrow, the thing the declaration explicitly does not supply, is an independent observable on cell steps that equals the posted flux for a reason other than being defined that way. That physical discharge remains an open target, and the declaration is honest about it.

/-- Clausius one-channel heat is the posting-rule atom behind each face of
`stepHeatCell`, but it is not a `PhysicalStepHeat`. The missing arrow is an

`q * ↑stepHeatCell` for a reason other than defining it that way. -/

What this page does not claim

The declaration does not claim that the posted flux equals a measured physical heat. It does not claim that any logical-bit reset protocol forces the erasure debit. It does not claim that thermal calibration or SI units are in scope.

Verify this page

Every tagged claim above names its theorem. To check one yourself rather than trust this page, elaborate the source module with Lean 4 and audit its axiom basis:

$ lake env lean IndisputableMonolith/Holography/LandauerBridgeWalls.lean
expected axiom basis: [propext, Classical.choice, Quot.sound] (the Lean kernel's standard three; no RS-specific axioms)

A page whose claims cannot be reproduced this way does not ship. In production, every anchor links to the exact declaration in the public source release, and this block carries the build receipt for the page itself.
