Alexander Zielonka	be6eaee6d0	fix(01-02): TS-strict narrowing for EvalResult discriminated union ... Rule 1 deviation: TS strict mode (noImplicitAny + strict) couldn't narrow the EvalResult union via 'r.ok' direct access because the {unknown:true,raw} variant has no 'ok' property. Added explicit type-guard helpers (isUnknown, isOk, isFail) for both production and spec narrowing. Runtime behavior unchanged; tsc --noEmit now exits clean for the leveling lib. Files: - prereq-evaluator.ts: 3 type-guard functions, used in OR/AND walkers - prereq-evaluator.spec.ts: isFail() in lieu of result.ok=== checks	2026-04-27 14:18:10 +02:00
Alexander Zielonka	da82d9bf82	feat(01-02): implement prereq-evaluator (D-01..D-04) ... Task 3 GREEN phase. Three-layer parser + evaluator + German formatter. Evaluable patterns (D-01): - Skill rank: 'Trained in Athletics', 'Expert in Stealth', etc. - Disjunctive OR-list (Oxford comma): 'X, Y, or Z' - Conjunctive AND: 'X; Y' - Bare feat name (Title Case, ≤4 words, no function words) - Heritage: '<name> heritage' - Class ref + Ancestry ref (against known sets) - Level ref: 'level N' Non-evaluable (D-02 → {unknown, raw}): - Spellcasting tradition refs (spellcasting class feature, divine spells, etc.) - Deity / worship-of refs - Age / ethnicity refs - Vision/sense traits (low-light, darkvision, scent) - Free-text sentences (heuristic: contains 'you', 'a', 'the', 'of', 'and', 'to') UNKNOWN-aggressive: any unknown atom in OR or AND poisons the whole prereq. German failure reasons (D-15): 'Du benötigst...', 'Dir fehlt das Talent...', 'Voraussetzung nicht erfüllt: ...'. 19 tests passing.	2026-04-27 14:09:43 +02:00
