- Pidgin lexer: words, escaped phrases (strict closing), parens - Full-Pidgin token-level parser, strict: malformed input throws SearchSyntaxException (BREAKING: lenient degradation removed from the plan; M7 must surface the error, M8 USAGE.md documents strict behavior) - AST with reference-equality collection terms; structural comparison lives in the test-side SearchNodeComparer (YYC MARK note records the record-equality pitfall) - SQL compiler: parameterized predicate over cards alias, LIKE escaping, COLLATE NOCASE exact matches, tag EXISTS / column IN subqueries - Markdown exporter: ResX-driven templates, per-language export time AND card time patterns, kebab i18n file names, table cell escaping - New RgbColor value type (byte components, strict #RRGGBB parse, canonical lowercase text) wired through TagModel and repository - 57 new tests (grammar branches, strict errors, SQL end-to-end, en/zh export snapshots, color conversions)
