AgDR Changelog

Phoenix SDK v1.8.1 (April 2026) — Tamper-Resistant Timing

Added libc dependency for POSIX clock_gettime binding
Implemented monotonic_raw_nanos() helper using CLOCK_MONOTONIC_RAW (Linux) with fallback for other platforms
Added monotonic_nanos field to SealedRecord for forensic chain integrity
Updated Rust edition to 2021 for improved pyo3 compatibility
Optimized release profile: LTO, strip symbols, panic=abort for production deployments
Wall-clock timestamps (timestamp field) retained for legal mapping; monotonic timestamps (monotonic_nanos) ensure tamper-resistant ordering

Phoenix SDK implements the AgDR specification. Spec version unchanged; only implementation enhanced.

Completed getting-started.md — full implementation guide with SDK usage, PPP guidance, human delta and FOI examples, and next-steps navigation
Added foi-formal-definition.md — formal definition, designation process, data structure, liability mapping, and multi-FOI registry for the Fiduciary Office Intervener
Added human-delta-chain-spec.md — complete data structure spec for the human delta chain including action codes, invariants, timing requirements, and legal significance
Added PPP triplet, human delta chain, and AgDR record JSON schemas to specs/agdr-v0.2.json
Added ppp-industry-templates.md — sector-specific PPP definitions for capital markets, healthcare, government, legal, financial services, and critical infrastructure
Added beauty-truth-wisdom.md — formal explanation of the three closing principles of the Purpose pillar
Added eu-ai-act-mapping.md — article-by-article mapping of AgDR v0.2 to EU AI Act (Regulation 2024/1689) high-risk obligations including GDPR interaction
Added verification-audit-procedure.md — CLI, Python, and manual cryptographic verification methods; court-ready evidence packaging procedure
Added horizontal-scaling.md — Root Merkle Coordinator architecture for scaling beyond 2.85B single-process ceiling with throughput table and evidentiary properties
Added sdk/python/ — agdr-aki Python SDK reference implementation (capture, delta chain, verify, evidence packaging, pyproject.toml)
Removed empty archive stub
