# THIRD-PARTY NOTICES — source-level ports, adaptations, and provenance Cosmogonic Quantum Mechalogodrom is owned by 0thernes — © 2026 (see [LICENSE](./LICENSE)); released under a non-commercial research & play license (study / run / modify / share non-commercially, keep attribution, no for-profit use). This file is the **source-level** attribution for algorithms that were ported / adapted into this project's own TypeScript from third-party research code. It complements [NOTICE.md](./NOTICE.md), which lists the bundled runtime dependencies and fonts. The quantum- and spin-mind layer of the apex **Super Creature** contains a mixture of compatible source-level algorithm ports and independent deterministic adaptations informed by **Tsotchke**, **Eshkol**, and **Moonlab**. The table states the relationship for each entry; –adapted— must not be read as gate-for-gate parity. MIT notices are retained below for the MIT-licensed upstream works. Repositories with different or missing licenses are governed by the per-repository boundaries in [the integration map](./docs/TSOTCHKE-INTEGRATION-MAP-2026-06-26.md). > **Tsotchke evidence boundary (updated 2026-07-10).** The corpus contains substantive implementations > of stabilizer, tensor-network, QEC, VQE, QGT, AD, spin/Hopfield, symmetry, and RNG techniques. License, > maturity, and integration depth differ by repository and are never inferred from the corpus as a whole. > Cosmogonic's runtime evidence is deterministic classical simulation; it does not establish physical-QPU > speedup, hardware entropy, cryptographic security, or experimental quantum behavior. A local bridge or > facade is described as such without diminishing or inflating its upstream source. ## Ported primitives | Adapted algorithm | Ported into (ours) | Upstream source | | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Quantum Geometric Tensor / Fubini–Study metric** (Re = metric, Im = Berry curvature) | `src/math/quantum-geometry.ts` (`quantumGeometricTensor`), consumed by `src/sim/super-qubits.ts` (`QuantumMind.geometricMetric`) | Tsotchke `quantum_geometric_tensor` (QGTL): `quantum_geometric_metric.c` / `…_curvature.c` / `…_gradient.c`; **Moonlab** `src/algorithms/quantum_geometry/qgt.c` (`qgt_metric_at`) | | **Deterministic statevector RNG adaptation** (2–8 classical-simulated qubits, unitary gates, Born collapse, snapshot/restore, and diagnostic repetition/adaptive-proportion-style counters); independent adaptation, **not** the former phase-array gate-for-gate port | `src/math/deterministic-statevector-rng.ts`; compatibility API `src/math/eshkol-qrng.ts` (`EshkolQrng`) | Tsotchke `quantum_rng` **v3.0.1**, commit `a00ad483cbbef31ea7536f09ae99409d81c9a823`; MIT reference implementation.

The QGT and spin/Hopfield paths retain their separate attributed algorithm lineage. `src/math/eshkol-qrng.ts` now preserves an existing API over the independent statevector adaptation; it is no longer an Eshkol phase-array measurement-source port. ### Deterministic adaptation (intentional) The upstream QRNG uses host/hardware entropy pathways. Cosmogonic's determinism law (CLAUDE.md; ADR 0004; `docs/PHILOSOPHY-2026-06-26.md`) forbids unseeded randomness and clocks in simulation logic. The local implementation therefore uses an explicitly seeded classical statevector model whose snapshot replays the same stream. This is a different execution contract, not an entropy-source substitution that preserves gate-for-gate upstream equivalence. ## Academic references (geometric tensor) - R. Provost & G.
