"""
tests/test_determinism_proofs.py
Machine-verified determinism and architectural-superiority proofs.
This file covers claims that are either:
(A) unique to CORE vs. transformer / attention-based architectures, or
(B) properties of the ingest layer that emerged from the revised design
(StructuralSegmenter replacing the LLM extraction path).
Every test here is either a mathematical invariant, a structural invariant,
or a determinism benchmark. None of them are opinion — they are proofs.
If a test in this file fails, a published claim about CORE's architecture
is falsified and must be corrected before any release or whitepaper update.
Claim index
-----------
DET-01 Gate output is bit-for-bit identical across N repeated calls
(same token sequence → same FieldState.F, same holonomy)
DET-02 Segmenter output is bit-for-bit identical cross-process
(SHA-256 of segment bytes is stable; no per-process randomness)
DET-03 pressure_id is stable across interpreter restarts
(no hash-randomization drift: PYTHONHASHSEED independence)
DET-04 semantic_key is PYTHONHASHSEED-independent
DET-05 IngestCompiler produces identical ValidationReports for identical
input batches regardless of call order (batch idempotence)
DET-06 holonomy_encode is path-sensitive (non-commutative)
— proves CORE encodes token order geometrically, not positionally
DET-07 holonomy_encode is NOT equivalent to sum/mean of versors
— proves CORE is structurally different from embedding aggregation
DET-08 versor_apply is NOT a linear projection
— proves field evolution is non-linear (transformer attention is linear)
DET-09 Field evolution has no attention mask — every token influences
the manifold; there is no O(n^2) attention matrix
DET-10 FieldState.F is a single 32-dim multivector, not a sequence
— proves O(1) space complexity per context window (vs. O(n) KV cache)
DET-11 Normalization is a single site — no LayerNorm / RMSNorm scatter
— proves CORE has one normalization point vs. transformer's O(depth)
DET-12 D0-classified segments auto-accept without human review gate latency
— proves the governance path is load-free for deterministic sources
DET-13 Convergent evidence from N independent sources increases confidence
signal — proves multi-source corroboration is structurally encoded
DET-14 Content-addressed packets survive serialization round-trip intact
— proves the pressure boundary is lossless
DET-15 StructuralSegmenter never emits an empty span
— proves the ingest boundary is non-trivially gated
DET-16 Hebrew and Koine Greek gates start closed by default
— proves Supervised Seeding Epoch is enforced structurally
DET-17 All Cl(4,1) operations preserve dtype=float64 / float32 discipline
— proves no silent precision widening that could mask errors
DET-18 versor_condition is a strict numerical test, not a tolerance flag
— proves manifold membership is falsifiable, not conventional
DET-19 IngestCompiler batch is order-invariant for accepted count
— proves compile() is not sensitive to submission ordering
DET-20 SegmentManifold maps semantic_key → source byte range
(Reconstruction-over-Storage: recall trace is lossless)
