v0.2.3 — receipt_id ordering fix + PyPI stable

AetherProof v0.2.3

Cryptographic AI execution receipt engine. Generates a tamper-evident
signed receipt for every AI inference — verifiable offline, forever,
with zero server dependency.

pip install aetherproof==0.2.3

What's fixed in this release

• receipt_id ordering bug fixed — receipts now order deterministically
  across all platforms; prior versions produced inconsistent ordering on
  Windows vs Linux
• PyPI package stable and tested on Python 3.9–3.12

What a receipt proves

Field	Proof
model_weight_root	SHA-256 Merkle of model — what ran
input_commitment	hash of input — what it saw
output_hash	hash of output — what it produced
timestamp_ms	when it ran — replay detectable
log_sequence	uint64 sequence — gaps detectable
signature	Ed25519 + ML-DSA-65 hybrid — tamper-evident

Compliance

• EU AI Act Article 13(3)(c) — technical documentation of AI decisions
• Offline-verifiable: Verify(receipt, public_key, log) = TRUE forever
• No cloud dependency, no vendor lock-in
