Session Handoff — BookifAI: revived the unreachable illustration feature into the live editor + fixed illustrations missing from exports

Where it started

Continued BookifAI (AI illustrated-book KDP studio; own stack React+Vite+TS + Supabase umnlokuehteqwrheoyai + Stripe + OpenRouter) from a pasted launch-hardening handoff. Session switched to Opus 4.8 [1m] partway. Sondra asked to open the app and find the watermark — that trace exposed a dead-code screen (BookPreview.tsx) that was the ONLY caller of the illustration feature, meaning interior illustrations were unreachable in the live app. All work stayed in TEST mode, 0 real users. She owns bookifai.app.

Decisions locked + what shipped

• Watermark rewired — it was built into dead BookPreview.tsx (imported nowhere) so it never displayed. New shared c:\Users\srver\AIOS-Workspace\aios-starter-kit\PROJECTS\Bookify AI Studio\app\src\components\create-book\PreviewWatermark.tsx; rendered in the REAL reading views: ...\app\src\pages\ChapterEditor.tsx (editor content) + ...\app\src\pages\ReviewPolish.tsx (manuscript tab). Shows when entitlement≠paid.
• CRITICAL: per-page illustration feature was unreachable — generate-illustration was called only from dead BookPreview.tsx. Extracted the proven logic into ...\app\src\lib\illustrate.ts (generateChapterIllustration + buildScenePrompt + 402 lock-reason mapper) and wired one-illustration-per-chapter into the live editor ...\app\src\pages\ChapterEditor.tsx: an on-page "Illustrate / Redraw / Upload your own / Remove" strip above the chapter text; cover used as the style/character anchor; persists illustration_url to the chapters DB row (CreateBook already maps it → exports pick it up).
• Un-gated illustrations from children's-only → ALL book types (PRD says illustrations aren't kids-only). Server-side metering (15 included/~40 cap, re-rolls count) unchanged; 402 → friendly upgrade toast; BYO upload is free/unmetered.
• Removed dead "Copy Share Link" button in ...\app\src\components\create-book\ExportOptions.tsx — it pointed at a /shared-book/:id route that doesn't exist (404). Public shared-book reader = deliberate future v1.1.
• Deleted ...\app\src\components\create-book\BookPreview.tsx (the misleading dead file that hid all of the above).
• EXPORT BUG (found after Sondra tested): illustrations missing from exports. Root cause: the four exporters in ...\app\src\lib\book-export.ts (downloadPdf, downloadHtml, downloadDocx, downloadPlainText) only embedded the COVER, never chapter illustrations (only the KDP Print Pack kdp-print.ts did). Fixed all four — HTML: <img class="chapter-img"> after each chapter heading; PDF: pre-inlines each illustration as a data URL via new inlineImage() helper (cross-origin-safe, same as cover); DOCX: new buildImageRunFromUrl() → centered ImageRun after each heading (loop switched forEach→for-await); TXT: honest [Illustration on this page — see the PDF/Word/KDP export] marker.
• Design decisions made (Sondra's proven pattern + PRD): one illustration per chapter on the chapter page (matches The Light Inside Her); user consciously clicks per chapter (safer for metering than auto-batch); extras via credits. Color-throughout for launch (KDP interior is all-or-nothing ink; kdp-print.ts is already premium-color; proven book was color). B&W/grayscale mode = easy future option, not a blocker.
• DB: restored her book 160bf885-560e-44fe-a84a-f0c6f0ee6a8b to entitlement='paid' in book_meters (was free for watermark viewing). images_used=0.

Key files for next session

• c:\Users\srver\AIOS-Workspace\aios-starter-kit\PROJECTS\Bookify AI Studio\app\src\pages\ChapterEditor.tsx — the illustration UI now lives here (per chapter, all book types).
• c:\Users\srver\AIOS-Workspace\aios-starter-kit\PROJECTS\Bookify AI Studio\app\src\lib\illustrate.ts — shared illustration helper.
• c:\Users\srver\AIOS-Workspace\aios-starter-kit\PROJECTS\Bookify AI Studio\app\src\lib\book-export.ts — chapter illustrations now render in PDF/Word/HTML/TXT.
• c:\Users\srver\AIOS-Workspace\aios-starter-kit\PROJECTS\Bookify AI Studio\app\src\lib\kdp-print.ts — KDP Print Pack (already rendered illustrations; the model to match).
• c:\Users\srver\AIOS-Workspace\aios-starter-kit\PROJECTS\Bookify AI Studio\PRD.md — §7.7/§7.8 billing/metering/illustration spec.
• Plan file: none (PRD is the spec).
• Memory files touched: none.
• Record updated: c:\Users\srver\AIOS-Workspace\aios-starter-kit\Sondra Brain\wiki\memory\open-questions.md (BookifAI section — CRITICAL gap + export bug documented).

Running state

• Background processes: shell bvf6yxfjs = npm run dev for BookifAI (from a prior session, still serving; confirmed HTTP 200 this session). Kill via TaskStop on that ID, or ignore.
• Dev servers / ports: http://localhost:8080 (BookifAI Vite, HMR live).
• Open worktrees / branches: none. App is its own local git repo; nothing committed this session.

Verification — how to confirm things still work

• cd "c:/Users/srver/AIOS-Workspace/aios-starter-kit/PROJECTS/Bookify AI Studio/app" && npx tsc --noEmit → exit 0 (was clean at end of session).
• Illustration is real + public: curl -s -o /dev/null -w "%{http_code} %{content_type}\n" "https://umnlokuehteqwrheoyai.supabase.co/storage/v1/object/public/covers/illus_160bf885-560e-44fe-a84a-f0c6f0ee6a8b_ch3_1783525664561.png" → 200 image/png.
• DB state (supabase MCP execute_sql on umnlokuehteqwrheoyai): select entitlement, images_used from book_meters where project_id='160bf885-560e-44fe-a84a-f0c6f0ee6a8b'; → paid, 0. select chapter_number, illustration_url is not null from chapters where project_id='160bf885-560e-44fe-a84a-f0c6f0ee6a8b'; → ch.3 true.

Deferred + open questions

• Open (only Sondra can do it): re-export her book (PDF / Word / KDP Print Pack) at localhost:8080 → confirm the ch.3 illustration now appears in the file. The browser-only render (jsPDF/docx/print-window) can't be verified headless.
• Open (offered): "no choices on how to illustrate" is by design (one click, cover as anchor). If she wants an art-style picker / regenerate-variations, it's an easy add — awaiting her call.
• Deferred: "Illustrate all chapters" one-click; B&W/grayscale mode; shared-book public viewer (replaces the removed 404 share button).
• Open (launch-day flips, her go): Stripe TEST→LIVE (STRIPE_API_KEY_MAIN + live products/webhook), email-confirm ON in Supabase Auth, deploy to bookifai.app. App is otherwise build-complete + safety-checked.
• Open ($20/mo Resend upgrade, deferred): send app emails from @amplifaiyourbusiness.com vs current verified sondraverva.com display name.
• Housekeeping (unrelated to this session): unprocessed skill marlowe-vsl-closer.skill in _INBOX-DROP-FILES-HERE\new skills to add\ awaiting the full skill-drop workflow.

Pick up here

Sondra re-exports her book to confirm the Chapter 3 illustration now lands in the PDF/Word/KDP file; once she's satisfied illustrations work end-to-end, the only remaining work is the launch-day flips (Stripe live → email-confirm on → deploy to bookifai.app).
