Date: 2026-08-08 20:12 Summary: Implemented full pdf-watermark tool with pdf-lib, 10 locales, and all gates green.

[question] Implement full pdf-watermark in /Users/xuli/vscodeai/onlinefreetools.

Spec

• slug: pdf-watermark, category: pdf, #56
• work-tasks/pdf-watermark ready. Title: "PDF Watermark — Stamp Text on Every Page Locally"
• Tech: pdf-lib CDN. Text watermark on every page via drawText (Helvetica). Controls: text, opacity (0.1–1), rotation degrees (-45 default), position (center/corners). Optional image watermark: if user picks PNG/JPG, embedJpg/embedPng + drawImage (scaled). related: check if add-watermark exists in catalog; if yes use ["add-watermark","pdf-page-numbers"] else ["organize-pdf","pdf-page-numbers"] (page-numbers may not exist yet — use ["organize-pdf","rotate-pdf"] then)
• loadSample(): 2-page PDF + text "DRAFT" → watermarked.pdf downloadable
• Privacy, 25MB, encrypted errors

Create catalog, icon, pdfWatermarkPage.ts, 10 i18n locales (full keys, independent).

Update 02/03 (1b+2b with en,zh,es,ja), inventory #56 已上线, README

Gates until green:

npm run merge:tools && npm run coverage:gate -- --slug=pdf-watermark --phase=all && npm run build:site && npm run lint:seo && CROSS_TOOL_UPDATE=1 TOOL_SLUG=pdf-watermark npm run lint:tool-isolation

No plan edit, no commit. 中文 brief. Chinese comments on code.

[try to solve] Finished full pdf-watermark stack; all gates green.

Deliverables

• src/site/tool-catalog.d/pdf-watermark.json — category pdf; related uses add-watermark + rotate-pdf because pdf-page-numbers was not live yet
• src/pages/pdfWatermarkPage.ts — pdf-lib drawText/drawImage; text/opacity/rotation/position/optional PNG·JPG; 25MB warn; encrypted errors; on-enter loadSample() two pages + DRAFT → watermarked.pdf
• public/icons/tools/pdf-watermark.svg
• src/site/i18n/tools/pdf-watermark/{en,zh,es,ar,pt,id,fr,ja,ru,de}.ts — full keys, independent rewrites
• work-tasks/pdf-watermark/02-tool-info.md, 03-locale-briefs.md — 1b/2b multi-round; 03 → i18n-done
• docs/2026-08-08-tool-inventory-table.md #56 → live
• README.md zh+en tool-list entries

Gates (all passed)

• coverage:gate --phase=all
• build:site (catalog 51 tools)
• lint:seo
• lint:tool-isolation (CROSS_TOOL_UPDATE=1)
