[Bug] Model switching to Opus 4.8 when setting Fable 5 due to safeguard flags

This was the part of the chat that caused the trigger to fire.

Bug Description
The architecture insight — your own doctrine, inverted. /extract proved "the model is the judge, never the conveyor belt — code moves the bytes." Output is the mirror: the model composes structured content (HTML/JSON/markdown); deterministic Swift code renders the document. Never the model emitting raw .docx bytes (that's the lossy-copier trap again). And notably — this is exactly how Ollie's skills already work (build a JSON config → Node script renders), so it validates the shape.

The library picks, license-verified for your paid App Store build:

• PDF → native WebKit (tier 1), Typst (Apache-2.0, bundle-safe) only if you ever need PDF/A archival typesetting.
• XLSX → libxlsxwriter (BSD-2, actively maintained) — links as C exactly like llama.cpp, so it doesn't break your zero-Swift-deps posture. Clean winner.
• DOCX → a real fork: SwiftDocX (MIT, but would be your first SPM dependency) vs hand-rolling OOXML (reuses the ZipArchiveReader you already built — the house pattern, zero-dep) vs NSAttributedString→docx. Worth a small spike before committing.
• pandoc / LibreOffice are GPL/MPL — can't be bundled into the sold binary, but shell-exec to a user install is license-clean, and that's the immediate path for Ollie's Node skills.

The bundle-safe stack (WebKit + libxlsxwriter + a permissive docx path) ships cleanly. First step when it gets a slot: a /document skill — content + template → HTML→PDF via WebKit → .pdf + a provenance receipt. It goes through the house pipeline like everything else.

This is a genuinely strong asset to add, and the fact that PDF — the format that matters most — is free and native means the "best in the world" bar is actually reachable without touching your dependency posture.
