a lost sign becomes a detector

Interpretive mapIntegrator

Organizes thought or workflow but is not evidence for a physical claim. joins several typed results while letting the weakest edge set the claim.

Exact assertion

The exact map sends central endpoint transports +I2 and -I2 to binary signs +1 and -1. It preserves composition, and a second traversal squares the negative return to +I2. Projector-only detection erases the sign, while determinant also misses it because det(-I2)=+1. A successful measurement therefore needs projector closure plus coherently referenced endpoint-frame tomography and a one-loop/two-loop parity control.

What this commits us to

The claim supplies a map or analogy. It becomes a derivation only after an explicit carrier-preserving map and invariant are given.

Logical anatomy

Scope

Chapter “The admissibility frontier”, section “a lost sign becomes a detector”. This is assertion 2 of 3 in that section.

Evidence posture

Treat the passage as organization or analogy unless a cited carrier-preserving map is supplied.

Research move

joins several typed results while letting the weakest edge set the claim.

Verification route

  1. Recover the declared objects and assumptions from the controlling documents.
  2. Check the calculation, construction, obstruction or stopping rule on those same objects.
  3. Compare the source conclusion with the exact assertion above; do not strengthen its verbs or enlarge its domain.
  4. Apply the status rule and retain every named external dependency.

What would move or defeat this claim

Provide an explicit map that preserves the claimed structure, then identify an observable consequence that the analogy alone did not supply.
