chore: release v1.1.0 - #262

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

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

What's in this release

Performance

• Hash-join replaces nested-loop join (O(N) vs O(N²)) — perf(post-1.0): hash-join negation inner loop #202, perf(post-1.0): hash-join disjunction inner loop #203, perf(post-1.0): hash-join with-grouped aggregation cross-product #204
• Selective B+Tree fact fetch for bound entity/attribute queries — perf(post-1.0): B+Tree selective lookup for bound patterns #208
• Predicate push-down, cost-based not/or ordering — perf(post-1.0): cost-based optimizer extensions for new clause types #205, perf(post-1.0): optimize mixed rule evaluation #206, perf(post-1.0): predicate push-down for expression clauses #207
• SIMD benchmarking infrastructure — Benchmark SIMD vectorization gains vs current scalar implementation #229

Bug fixes

• Critical correctness/durability bugs from deep audit — fix: critical correctness and durability bugs from deep audit #225
• Read-only handle Drop no longer modifies the file — [vulcan] minigraf_bug: MiniGrafDb::drop() writes to the graph file uncond #226
• QueryResult::Transacted/Retracted restored to tuple variants (was a breaking change) — fix(api): revert QueryResult tuple variants for 1.x compat; add current_tx_count() #261
• New additive Minigraf::current_tx_count() -> u64 exposes :as-of counter

Reliability

• WAL fault injection + crash-recovery matrix — test: add WAL crash-recovery matrix for commit boundaries and partial writes #209, test: add WAL durability fault-injection tests for fsync and write failures #210, fuzz: add WAL and file-format deserialization fuzz targets #214
• Storage/migration resilience, index corruption recovery — test: add index corruption recovery and rebuild fixtures #215, test: add legacy file-format migration matrix and corruption fixtures #216, test: add concurrency stress tests for read/write transactions and rollback paths #217
• Property-based query correctness, fuzz targets, coverage gates — test: add Datalog cross-feature property tests with a reference evaluator #212, fuzz: add Datalog parser and expression evaluator fuzz targets #213, ci: add coverage gates for critical reliability modules #219
• Long-haul smoke suite, XTDB/Datomic compat — test: add long-run real-world dataset reliability smoke suite #220, test: import XTDB/Datomic compatibility test corpus #221
• Clippy enforcement (336 violations fixed), grammar conformance harness — fix: add workspace clippy lint enforcement and fix all violations #232, [FEATURE] EBNF grammar specification and semantics documentation #233

Test plan

• 935 tests passing locally
• Pre-push hooks (fmt + clippy + test) green
• CI green → merge → tag v1.1.0
