Summary

Closes the last major Third-Door blueprint ⚫ rows (#21): trajectory invariants + zero-fabrication (R&D §2.2) and ADR-DAG conformal embedding (R&D §2.4).

Python is the geometry-first authority (deterministic algebra/*). Optional Rust Ring-1 port is deferred, not a second truth.

A. Trajectory invariants — `core/physics/trajectory_invariants.py`

Relative holonomy H = V_i · reverse(V_{i+1})
Divergence D = Σ log(1 + ‖H reverse(H) − 1‖) · Δt
Energy boundary E_exertion ≤ κ · E_sensory
Zero-fabrication: empty / short / non-closed refused

B. ADR-DAG embedding — `core/adr/validator.py`

Ψ(M): SHA-256 → 10×3-byte → c_k ∈ [−1,1] → planes 6..15 → simple-bivector project (dominant plane)
Master blade: successive wedge with sum fallback if wedge degenerates
Proposal drift: ‖B_p ∧ A_master‖
Not a parallel GeometricDelta ABI validator (core/abi/geometric_delta_validator.py remains envelope/closure ABI)

Ledger

Rows 7–8 → 🟢; §9 rewritten as landed surfaces.

## Summary Closes the last major Third-Door blueprint ⚫ rows (**#21**): trajectory invariants + zero-fabrication (R&D §2.2) and ADR-DAG conformal embedding (R&D §2.4). Python is the **geometry-first authority** (deterministic `algebra/*`). Optional Rust Ring-1 port is deferred, not a second truth. ### A. Trajectory invariants — `core/physics/trajectory_invariants.py` - Relative holonomy `H = V_i · reverse(V_{i+1})` - Divergence `D = Σ log(1 + ‖H reverse(H) − 1‖) · Δt` - Energy boundary `E_exertion ≤ κ · E_sensory` - Zero-fabrication: empty / short / non-closed refused ### B. ADR-DAG embedding — `core/adr/validator.py` - `Ψ(M)`: SHA-256 → 10×3-byte → `c_k ∈ [−1,1]` → planes 6..15 → simple-bivector project (dominant plane) - Master blade: successive wedge with sum fallback if wedge degenerates - Proposal drift: `‖B_p ∧ A_master‖` - **Not** a parallel GeometricDelta ABI validator (`core/abi/geometric_delta_validator.py` remains envelope/closure ABI) ### Ledger Rows 7–8 → 🟢; §9 rewritten as landed surfaces. ## Test plan - [x] `pytest tests/test_third_door_trajectory_invariants.py tests/test_third_door_adr_dag_embedding.py` (18 passed) - [x] goldtether + wave regression (76 passed total with those) - [x] smoke 108 passed ## Issue Closes #21.

Geometry-first Python authorities for the last Third-Door blueprint gaps:
- trajectory_invariants: relative holonomy, divergence integral, energy
  boundary, zero-fabrication refusals (R&D §2.2)
- core/adr/validator: SHA-256→bivector Ψ(M), simple project, master blade,
  proposal drift (R&D §2.4); not a parallel GeometricDelta ABI validator
