- WebSocket: WsServer wired to HttpServer via ExecutionContext.onChange
- INSERT/UPDATE/DELETE now broadcast to subscribed WebSocket clients
- CHECK constraints: evaluate AST expressions via evalExpr(lowerExpr())
- Works on both INSERT and UPDATE paths
- VIEW persistence: CREATE VIEW stores to LSM-Tree, restoreSchema loads views
- Migration tracking: APPLY MIGRATION marks applied with _schema:migrations:applied:<name>
- Update PLAN.md honesty for WebSocket, CHECK, Views, Migrations
- 216 tests passing
Executor:
- FOREIGN KEY enforcement: checks referenced row exists on INSERT
- Type enforcement: INTEGER, FLOAT, BOOLEAN, TIMESTAMP validated
- GROUP BY execution: actual row grouping with count(*) aggregation
- WebSocket broadcast: onChange callback wired into INSERT/UPDATE/DELETE
- CREATE INDEX handler: creates B-Tree index + populates from existing data
- ALTER TABLE ADD COLUMN: actually adds column to table definition
- LIKE evaluation with regex pattern matching
- FK metadata stored in ColumnDef (fkTable, fkColumn)
Parser:
- CREATE INDEX / CREATE UNIQUE INDEX parser added
- ALTER TABLE now parses ADD COLUMN with type
HTTP Server:
- Rate limiter wired (token bucket per client IP)
- CORS headers on all responses (Allow-Origin: *, OPTIONS preflight)
- 429 Too Many Requests when rate limit exceeded
All 216 tests pass
Critical bugs fixed:
- SELECT now returns actual row data (was returning empty arrays)
- WHERE filter evaluation now works (was pass-through stub)
- ORDER BY sorting now works (was no-op)
- UPDATE execution implemented (was no-op stub)
- DELETE uses WHERE filter (was key-match only)
- B-Tree point reads return actual row data (was returning count only)
- EXPLAIN returns plan string (was computed then discarded)
- UNIQUE constraint uses B-Tree index (was memtable scan only)
- DEFAULT values work for int/bool/float (was string-only)
- HTTP /query returns real JSON rows with columns
- Docker healthcheck uses wget (Alpine has no curl)
Updated PLAN.md with honest status:
- Marked what's truly done vs stub vs not implemented
- Honest score: 8/10 (not 9.5/10)
- Clear list of what actually works in production
All 216 tests pass
