[0.6.0] — 2026-06-03

A large openCypher conformance release. TCK pass rate moves from 91.5% (3549 executable scenarios) to 97.7% (3788 / 3876), +239 scenarios with zero regressions among previously-passing scenarios. 944/944 unit tests pass; functional tests clean.

Added — openCypher coverage

• Pattern & path matching completeness — variable-length path hydration, relationships() / nodes() on varlen and null paths, path-wide relationship uniqueness, multi-rel OPTIONAL MATCH with full-pattern (all-or-none) semantics, bidirectional bracketed relationship patterns, and four-label conjunctions in expression context.
• Temporal — closed the non-DST temporal cluster: duration arithmetic and ISO round-trip normalization (months not normalized across days; 1 month = 30.436875 days), duration.between, component accessors, date/time/ datetime/localdatetime construction and selection, named-zone handling, and UTC-instant ordering. Cross-type ordering now uses an orderability comparator with a NaN sentinel and an overflow-safe (seconds, nanoseconds) temporal comparison (far-future years no longer wrap int64 epoch-nanoseconds).
• Quantifiers — all / any / none / single over list pipelines now evaluate consistently; non-deterministic CTEs (rand()/RANDOM() in WITH projections) are emitted AS MATERIALIZED so a multiply-referenced list is evaluated once, fixing algebraic-identity scenarios.
• WITH / ORDER BY / aggregation — ORDER BY on a non-aggregating WITH now flows to a downstream aggregating WITH (… ORDER BY x WITH collect(y) collects in sorted order); computed (non-aggregate) WITH keys (e.g. a.n % 3 AS m) are now GROUP BY keys; LIMIT/OFFSET inline into the WITH CTE body.
• Existential subqueries — EXISTS { pattern } brace form.
• Validation — compile-time SyntaxError diagnostics (pattern expressions in SET RHS, relationship-uniqueness, label/type 3-valued-logic predicates, and more).

Fixed

• Multi-row MATCH … CREATE / MATCH … DELETE … CREATE runs the write per matched row; inter-pattern variable references in CREATE ({x: a.id}) resolve against earlier patterns; RETURN is pre-captured before DELETE.
• REMOVE on a null/unbound variable is a no-op; RETURN * excludes synthetic anonymous aliases.
• General-expression projection in CREATE … RETURN and SET (list/JSON props).

Notes

Remaining gaps (~2.3%) concentrate in DST-aware timezone arithmetic, nested existential subqueries, multi-row MERGE binding, and boolean subtype preservation (SQLite has no native boolean type). See https://github.com/colliery-io/graphqlite/blob/main/docs/testing/semantic-coverage-matrix.md. Windows extension tests (test_*_timestamp*) remain non-blocking pending an
