Execute golden-path transcripts, wrong-attempt testing, save/reload persistence checks, and harden the automated parser-driven walkthrough
Run specialized review passes (puzzle fairness, vocabulary audit, state audit) and maintain progressive parent-child hint UX
Write player-facing prose, NPC dialogue trees, layered hints, and ensure every noun in text resolves through the parser
Translate design docs into a coherent simulation plan — validate puzzle fairness, audit parser vocabulary, and prevent softlocks before writing ZIL
Test target-audience approachability and accessibility through explicit player personas, fresh sessions, and evidence-based usability findings
Fix technical and functional ZIL defects found during staged QA, including parser, object, exit, persistence, progression, and NPC failures
Run blind functional play-throughs with @tester, collect player-visible evidence, and prepare functional regressions
Coordinate independent technical, blind functional, artistic, and audience-accessibility release passes for a packaged ZIL adventure
