Sources files and media

Use Add a link or note, or Upload a file. Signed-in imports read real source text and metadata, then attempt analysis. Without model credentials, the source is still saved with an explicit warning and remains Needs review. Without sign-in, URLs are saved as unfetched links and provided text stays in browser storage. No completed fetch or model result is simulated.

Uploads support images and common text/code formats up to 2 MB, including Markdown, JSON, CSV, HTML, TypeScript, Python, C/C++, Rust, Go, CSS, SQL, and configuration files. The agent only reads files you upload; it cannot browse arbitrary folders on your computer. PDF and Word parsing are not implemented.

Page fetching is limited to 1.5 MB; readable page text is capped at 60,000 characters, with at most 22,000 sent to the source analysis model. Full uploaded file text is stored and searchable; model reading uses bounded chunks.

Public fetching validates and pins DNS addresses, checks each redirect, blocks local/private networks, caps response size, and times out. Included links are followed only when selected, up to three per import. Model-generated tags and articles remain Needs review.

Real page screenshots require:

1npx playwright install chromium

Set ENABLE_SCREENSHOTS=true and restart. Chromium is installed and capture is enabled in this workspace's private local environment. Screenshot capture is restricted to the source hostname, with service workers, downloads, and WebSockets disabled; cross-domain assets may be missing. This is a real capture, not a generated cover. Live capture through the authenticated agent still needs end-to-end verification. The free vision adapter has been tested against the real BoardUI screenshot.

Curated covers are original source screenshots and the original thumbnail from Nero's BoardUI post. Provenance is in public/previews/sources.json. The X video opens on its original source because the CDN rejected localhost playback. Notes without media have no cover. Remote access blocks are reported; pasted text or original uploaded screenshots can supply the evidence.
