dimgigov	cf2aba104f	Phase 5 complete: B-tree property tests + benchmark regression suite ... - prop_test.nim: 11 new property-based B-Tree invariants (size accuracy, get roundtrip, scan ordering, range correctness, contains, remove, large order, duplicates, empty tree, interleaved ops) - bench_all.nim: JSON-based benchmark result tracking with regression comparison against previous runs; each benchmark reports ops/sec delta vs last run	2026-05-18 12:52:44 +03:00
dimgigov	5dba7b5699	feat: Phase 1 — SSTable persistence, README honesty, benchmark fix ... - Add Current Status / Limitations section to README - Fix benchmark compilation (Duration.ticks → inNanoseconds) - Implement real SSTable binary format with write/read/mmap support - Add BloomFilter serialize/deserialize for disk storage - Fix mmap.nim to use posix.open instead of system.open - New PLAN.md with improvement roadmap - All 214 tests pass	2026-05-06 03:16:39 +03:00
dimgigov	eecd846df9	feat: UDF stdlib, SIMD vector ops, benchmarks — 162 tests ... - User Defined Functions: register/call/deregister, stdlib (math, string, type conversion, array) - SIMD vector operations: unrolled dot product, L2, cosine, manhattan, normalize, batch distance - TopK and batch distance for vector search - Performance benchmarks (LSM, B-Tree, HNSW, FTS, Graph) - All roadmap phases marked complete except cluster/optimizations tail - 26 new tests (162 total, all passing)	2026-05-06 01:33:51 +03:00
