Gravity Seven Gaps Stationarity Bridge Closure Stationarity Bridge Closure Statu

The closure status

The declaration stationarityBridgeClosureStatus_flags is a small, machine-checked record of what has been achieved and what has not. It sets two boolean flags. The first, constitutive_stationarity_bridge_closed, is true: it records that a certain ratio, central to the framework's account of gravity, has been derived from an explicit model of how deficits in a system act as sources. The second, derivation_from_bare_ledger, is false, and the declaration proves it stays false.

To understand the flags, picture a ledger: a discrete record of recognition events, which the framework treats as the primitive substrate of reality. The question is whether the ratio that links geometry to recognition can be derived from this ledger alone. The answer, established by this declaration, is no. The derivation requires an additional, disclosed premise: a specific coupling between a geometric deficit and a source term, which the framework labels a constitutive model. This premise is not derived; it is chosen. The flags therefore mark the boundary between what is proved and what is assumed.

The positive flag is grounded in a constructor, recognitionRatioBridge_ofStationarity, which takes the constitutive model as input and proves the ratio relation from stationarity. The negative flag is grounded in a separate, kernel-checked result that kills the bare-ledger route as circular. The declaration itself, stationarityBridgeClosureStatus_flags, is a theorem: it proves that the first flag is true and the second is false, with no unproved assumptions. It does not, however, decide how the broader campaign ledger records this closure; that remains a conductor's choice, not a mathematical one.

What the declaration does not claim is as important as what it does. It does not claim that the ratio is derived from the bare RecognitionLedger; that route is explicitly dead. It does not claim that the constitutive coupling is derived; that remains a model. And it does not claim that a full tower of bridge structures, one for every mesh scale with a shared remainder constant, has been built; that asymptotic object remains open. The flags are a precise statement of a partial victory: a derivation from a specific, named model, and a permanent refusal to overstate the derivation's source.

* `constitutive_stationarity_bridge_closed = true` is grounded in the
  constructor `recognitionRatioBridge_ofStationarity` (which PROVES
  `ratio_relation` from `stationaryRatio_cubic`, taking only structural
  side conditions) together with the uniform-family theorem
  `quadraticSourceFamily_isAdmissible` and the concrete instance
  `concreteStationarityBridge`. The bridge is derived from an explicit
  deficit-source constitutive action plus J-stationarity, never from the
  bare RecognitionLedger.
* `derivation_from_bare_ledger = false` STAYS false: the deficit-source
  coupling inside `sourcedAction` is the disclosed constitutive MODEL
  premise, and the kernel-checked kill records in `HingeStationarityCore`

  `budget_implies_ratio_without_stationarity`) prove the bare-ledger

What this page does not claim

The ratio relation is not derived from the bare RecognitionLedger alone. The constitutive deficit-source coupling is not derived; it is a chosen model premise. The declaration does not build a mesh-indexed tower of bridge structures; that remains an open target.

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/Gravity/SevenGaps/StationarityBridgeClosure.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.
