feat(ucns): declare and instantiate scale-transform substrate

[erinepshovel-code]

Purpose

Make UCNS's scale/representation jurisdiction explicit and add the first narrow executable component of that architecture without importing domain semantics.

Architecture

• METAPAT: cross-domain semantic authority and transfer constraints
• UCNS: geometry / mathematical representation and scale transport
• EDCM: measurement and evaluation
• consumers: domain meaning and evidence

Current METAPAT v4 was consulted before the boundary was changed.

Implementation

Adds src/ucns/scale_action.py, an exact domain-agnostic candidate action

T_q(x)_i = q^w_i x_i

over positive exact-rational coordinates, with:

• exact integer weights;
• exact multiplicative composition T_p o T_q = T_(p*q);
• identity and reciprocal inverse;
• exact monomial scale weight sum(a_i*w_i);
• invariant-kernel test;
• replayable application receipts;
• no domain axis names or interpretations in the core.

The candidate is deliberately narrower than a universal ScaleTransform law. It does not yet bind native Möbius origin/attachment, recursive carrier transitions, or the higher-dimensional UCNS construction.

External physics fixture removed from UCNS

The conditional six-axis physics fixture formerly drafted here has been moved to Stack PR #56:

The-Interdependency/stack#56

UCNS now keeps only the domain-agnostic scale-action machinery. The external physics fixture owns the names (epsilon, mu, c, hbar, m, L), confinement/Compton algebra, and all physical interpretation under Stack provenance. No physics premise, trapped-field claim, varying-constants claim, or cosmological claim transfers into UCNS.

Documentation / agent boundary

• promotes scale/representation jurisdiction into CANON.md;
• adds the placement test to AGENTS.md and CLAUDE.md;
• updates README.md;
• adds docs/scale-transformation-jurisdiction.md;
• preserves the incomplete composition/origin boundary as hmmm;
• deletes the misplaced UCNS physics fixture.

Tests / contracts

The new module owns MODULE_BUILD + five CONTRACTS; tests/test_scale_action.py owns the resolving CHECKS, including facade exposure.

hmmm

The exact law binding this multiplicative action to UCNS origin/attachment, native Möbius transport, recursive carriers, and the full circle → epicycle → disk → sphere → recursive-scale construction remains unresolved.

P2 placement finding: preserve the domain-neutral scale action in UCNS, but move the physics-domain fixture out of UCNS. This PR correctly declares that domain meaning/evidence stays with the consumer and METAPAT domain-restraint says structural recurrence does not transfer domain terms, mechanisms, or evidence standards. docs/scale-transform-physics-fixture.md nevertheless makes UCNS the host of epsilon/mu/c/hbar/m/L names, a varying-constants hypothesis, Compton/confinement interpretation, and particle-physics falsification criteria. Keep the exact T_q action, invariant-kernel machinery, and a domain-neutral fixture/interface here; put the physics binding in the consuming/incubating physics research layer (Stack unless another source owner exists) and link it by exact source identity. Re-run exact-head geometry CI and review after the move.

[erinepshovel-code]

Executed the requested placement repair.

• Deleted the misplaced UCNS physics fixture.
• Updated README and scale-transformation jurisdiction docs so UCNS owns only the domain-agnostic scale-action candidate.
• Moved the conditional physics fixture to Stack and merged it as docs(physics): consume UCNS scale-action fixture outside core stack#56 at daf5ed81f9964bccbe79330bc6ab9dfb0438c918 after the Stack consistency workflow passed.

Current UCNS head is a374e2a8f08be2140d88a0ab24daaad2e5a98864; geometry CI is still running at this comment. Merge should wait for the current exact-head workflow and review.
