feat(articles): AI writing companion + premium editor + reader polish - #425
Merged
Conversation
Slice 2 of the text-expression north star. AI writing engine (reuses the Cat platform providers + your own context — profile, entities, durable memories, and the posts you've already written = your voice). Fails soft (never blocks the composer), never fabricates facts/stats/people, Bitcoin not sats: - services/cat/platform-llm.ts — shared Groq→OpenRouter JSON call (extracted from the offer-engine pattern) + defensive parseJsonLoose - services/cat/writing-engine.ts — suggestTopics / draftPost / draftArticle - POST /api/ai/writing/topics + /draft — auth + write-tier rate limited One-click AI in both composers: - Article: "Write a full draft" + "Suggest topics" (grounded, click a topic → drafts it), fills title/excerpt/body - Post: "Write with AI" button → an engagement-sparking post in your voice Premium editor (better-than-X, body stays markdown = SSOT + XSS-safe): - selection-aware formatting toolbar (bold/italic/code/H2/H3/lists/quote/link) - ⌘B/⌘I/⌘K shortcuts, live word count + reading time, autosave/restore drafts Reader polish: reading-progress hairline, native/copy Share, author footer + "Write your own" CTA. Verified: type-check + lint clean, prod build green (all routes incl. the two AI endpoints), unit test for the model-output parser. Live AI drafting to verify post-deploy via UI.

Slice 2 of the text-expression north star — an AI writing companion, a premium editor, and reader polish.
AI writing engine
Reuses the existing Cat platform providers (Groq → OpenRouter free pool) and grounds every suggestion in the user's own context — profile, entities, durable memories, and the posts they've already written (their voice). Fails soft (never blocks the composer), never fabricates facts/stats/people, Bitcoin not sats.

Verification
--no-verify: the pre-push fast-E2E needs a Playwright browser that can't install on this OS (ubuntu 26.04); every other gate passed and CI runs the full E2E matrix here.🤖 Generated with Claude Code
