Changed

• Version bump to 0.3.1 across all workspace crates
• Refactor oxirs-fuseki/src/config.rs (1999 lines) → split into config.rs + config_server.rs + config_security.rs + config_runtime.rs; public API preserved via re-exports
• Refactor oxirs-arq/src/lateral_join.rs (1978 lines) → directory module; test block extracted to lateral_join/lateral_join_tests.rs; source down to 1138 lines
• Refactor oxirs-federate/src/query_decomposition/advanced_pattern_analysis.rs (1990 lines) → split into _consciousness.rs (252) + _analyzer.rs (1484) + _quantum.rs (298) + 16-line facade
• Refactor oxirs-cluster/src/storage/persistent.rs (1953 lines) → persistent.rs (710) + persistent_wal.rs (335) + persistent_integrity.rs (444) + persistent_tests.rs (287)
• Refactor oxirs-shacl/src/targets/selector.rs (1961 lines) → selector.rs (709) + selector_query.rs (548) + selector_eval.rs (641)
• Refactor oxirs-shacl-ai/src/performance_monitoring.rs (1949 lines) → performance_monitoring.rs (1575) + performance_monitoring_advanced.rs (514); fixed pre-existing Duration/field-name/Serialize bugs
• Refactor oxirs-shacl-ai/src/optimization/engine.rs (1987 lines) → engine.rs (1308) + optimization/engine_analysis.rs (718)
• 21 TODO.md files updated: 47 [~] items flipped to [x] for RFC-001 (LTS) and RFC-002 (Enterprise) now that policies are published
• Dependency: SciRS2 workspace crates bumped 0.4.3 → 0.5.0 (all 12 scirs2-* sub-crates)
• Dependency: oxiarc-* compression crates pinned to 0.3.3 and consumed directly from crates.io — the temporary [patch.crates-io] path overrides were removed, leaving only pathfinder_simd patched (an unrelated Rust-nightly intrinsic fix)
• Refactor (Round 31 — facade recovery): 13 oversized files (1602–1909 lines) across oxirs-core, oxirs-vec, oxirs-fuseki, oxirs-embed, oxirs-shacl-ai, oxirs-samm, oxirs-rule, and oxirs converted to thin facades over pre-existing sibling modules (~20K lines net removed)
• Refactor (Round 32 — tier-2): oxirs-fuseki auth/saml.rs + bind_values_enhanced.rs, oxirs-cluster cluster_metrics.rs, oxirs-tdb advanced_diagnostics.rs, oxirs-federate service.rs, and oxirs commands/jena_parity.rs split into focused submodules
• Refactor (Round 33 — tier-3): oxirs-shacl constraints/expression_constraint.rs, oxirs-vec tree_indices.rs (ball/cover/kd/rp/vp-tree), oxirs-wasm query/construct.rs, oxirs-gql schema.rs, and oxirs-stream backend/kafka/backend.rs split into submodules
• Refactor (tools/oxirs): commands/aspect.rs, commands/interactive.rs, and commands/import_command.rs split into focused modules; lib.rs → lib_commands.rs + lib_dispatch.rs
• Refactor (additional): oxirs-gql validation_spec.rs, oxirs-tdb mvcc/mod.rs, oxirs-stream lib_types.rs / neuromorphic_analytics.rs / wasm_edge_computing.rs, and oxirs-core storage/tiered.rs split into module directories
• oxirs-vec: build.rs CUDA-toolkit detection now emits informational build-script output instead of cargo:warning= (no-warnings policy); GPU acceleration remains opt-in via the cuda feature with Pure-Rust CPU fallbacks
• Error-handling hardening: unwrap() calls in the benchmark runner and performance-benchmark modules replaced with context-carrying error handling

Changed — Pure-Rust (COOLJAPAN Policy)

• Compression: brotli → oxiarc-brotli, snap → oxiarc-snappy, flate2 → oxiarc-deflate across all consuming crates (tdb, stream, federate, fuseki, cluster, arq, gql, star, embed, shacl-ai, chat, did, tools); direct brotli/snap/flate2 deps removed
• Crypto: 27 first-party ring:: call sites (tools/oxirs, oxirs-did, oxirs-fuseki, oxirs-cluster) migrated to oxicrypto leaf crates (hash/mac/aead/kdf/rand) + workspace ed25519-dalek + rsa for Ed25519/RSA signatures; all direct ring deps removed
• TLS: pure-Rust oxitls::pure_provider() installed process-wide at every binary entry; rustls no-provider, reqwest rustls-no-provider, tokio-rustls default-features=false, metrics-exporter-prometheus push-gateway-no-tls-provider; cluster cert-gen rcgen → oxitls-rcgen; async-openai gated behind non-default openai feature
• Fixed an oxiarc-brotli incompressible-input compressor bug (it emitted streams its own decoder rejected); the fix shipped upstream as oxiarc 0.3.3 (2026-06-06) on crates.io, which OxiRS now consumes directly
• Default cargo build is now free of ring and aws-lc-sys/aws-lc-rs C/asm crypto — cargo tree -i ring and cargo tree -i aws-lc-sys/aws-lc-rs are all empty for the default feature set

Fixed

• oxirs-stream: fixed undefined behavior in neuromorphic analytics — NetworkTopology and NeuralResponse removed from the unsafe impl_zeroed_default! macro (std::mem::zeroed() is UB for Vec/Instant); replaced with derive(Default) and a manual Default impl (Round 31)
• oxirs-core: declared indexmap and toml as workspace dependencies, fixing a latent compile break in jsonld::{compaction,flattening} (Round 31)
• oxirs-vec: restored JointEmbeddingSpace::zero_shot_retrieval, lost to earlier module drift (Round 31)

Policy Compliance

• All .rs files under 2000 lines (proactive refactors applied)
• Zero warnings, zero errors across workspace
• Total test count: ~43,511 (+19 graphrag, +6 embed from Round 18)
