v1.1.0 — drop-in replacement for v1.0.0

No file-format changes, no public API changes, no query surface changes. Upgrading requires no code changes.

Performance

• Hash-join replaces nested-loop join for multi-clause queries — O(N) instead of O(N²) for large fact sets (#202, #203, #204)
• Selective B+Tree fact fetch: queries with bound entity/attribute skip full-scan (#208)
• Predicate push-down into join ordering (#207)
• Cost-based clause ordering for not/or rules (#205, #206)
• SIMD crossover analysis and benchmarking infrastructure (#229)

Bug fixes

• Critical correctness and durability bugs from deep audit (#225)
• Read-only handle Drop no longer modifies the file on close (#226)
• QueryResult::Transacted/Retracted restored to tuple variants — struct-variant form was a breaking change (#261)
• New additive Minigraf::current_tx_count() -> u64 exposes the :as-of monotonic counter

Reliability

• WAL fault injection + crash-recovery matrix (#209, #210, #214)
• Storage/migration resilience, index corruption recovery, concurrency stress (#215, #216, #217)
• Property-based query correctness tests, fuzz targets, per-module coverage gates (#212, #213, #219)
• Long-haul smoke suite, XTDB/Datomic semantic compatibility (#220, #221)
• Workspace-wide clippy enforcement, grammar conformance harness (#232, #233)
