Capture direct image URLs as image cards

[silverbucket]

Summary

• recognize common direct-image URL paths during quick capture
• verify the response is actually an image using Content-Type
• download and store image bytes in remoteStorage with the original URL retained as the source
• enforce the existing 25 MB image limit and a 20-second timeout
• fall back to a normal bookmark when CORS, networking, type verification, or size checks fail

Verified example

The supplied Rolling Stone URL returns image/jpeg, allows cross-origin GET requests, and is approximately 11.2 MB, so it will be captured as an image card.

Validation

• npm run check
• npm run test (844 tests passed)
• npm run check --workspace=@inbox-rs/web (0 errors)
• focused capture tests (16 passed)

Summary by CodeRabbit

• New Features

  • Direct image URLs can now be captured and stored with their metadata, thumbnails, and binary content.
  • Image downloads validate file type, size, and request timing before capture.
  • Bookmark capture now falls back gracefully when an image cannot be downloaded.

• Tests

  • Added coverage for direct image capture, metadata storage, binary data, and fallback behavior.
  • Improved test isolation by resetting global stubs after each test.

📝 Walkthrough

Walkthrough

captureDetected now attempts direct image capture for bookmark URLs. The new helper validates and downloads image files. Failed downloads use the existing bookmark or note path. Tests cover image storage, metadata, fallback behavior, and stub cleanup.

Changes

Direct image capture

Layer / File(s)	Summary
Direct image download validation packages/web/src/lib/capture.ts	downloadDirectImage validates image-like URLs, MIME types, response sizes, blob sizes, and timeouts. It returns a decoded File or null.
Capture integration and validation packages/web/src/lib/capture.ts, packages/web/src/lib/capture.test.ts	captureDetected builds and stores image items with source URLs, files, and thumbnails. It falls back to bookmark or note capture when image download fails. Tests cover both paths and restore global stubs after each test.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 3b458

Direct image capture can download an oversized response before enforcing the 25 MB limit, increasing bandwidth and memory usage instead of promptly falling back to a bookmark; valid images with uppercase MIME types may also be rejected. Address these bounded issues before merging.

A rabbit tests the image trail

A tiny file rides through the mail
If image winds should fail
A bookmark guards the trail
And clean stubs leave no stale detail

Security review

No medium, high, or critical vulnerabilities in this PR.

Reviewed the new downloadDirectImage path and captureDetected integration for injection, XSS, SSRF, path traversal, MIME confusion, and supply-chain risk.

Existing controls are sufficient for the change:

• Quick-capture only treats a single http/https URL as a bookmark, so javascript:, data:, and file: never reach the fetcher.
• The remote Content-Type must start with image/; size is capped at 25 MB and the request times out at 20s; failures fall back to a bookmark.
• Image bytes are stored under files/<uuid>.<ext> (UUID, not the remote filename) and rendered in <img> with Svelte-escaped titles, so SVG scripts do not execute in the app.
• The fetch runs in the user’s browser and is CORS-constrained; downloaded bytes stay in that user’s remoteStorage. No new dependencies.

In `@packages/web/src/lib/capture.ts`:
- Around line 49-50: Update the response-reading logic in the capture flow to
consume response.body incrementally, track accumulated bytes against
MAX_DIRECT_IMAGE_BYTES, and cancel the stream immediately when the limit is
exceeded instead of calling response.blob() first. Preserve successful blob
creation for bodies within the limit, and add a regression test covering a body
larger than 25 MB without a Content-Length header.
- Around line 37-38: Normalize the MIME essence to lowercase in the capture flow
before validating it with startsWith('image/') and before passing it to File.
Add a regression test covering Content-Type: IMAGE/JPEG and assert the resulting
image file uses the normalized MIME type.

Security review

No medium, high, or critical vulnerabilities in this PR.

Re-reviewed downloadDirectImage and the captureDetected integration after 390a2f6 (streaming size cap, MIME lowercase). Prior automation findings still do not apply; no inline issues remain.

Checked injection, XSS, SSRF, path traversal, MIME confusion, and supply-chain risk:

• Quick-capture only treats a single http/https URL as a bookmark, so javascript:, data:, and file: never reach the fetcher.
• Response Content-Type must start with image/; bodies are read incrementally and cancelled over 25 MB; requests time out at 20s; failures fall back to a bookmark.
• Image bytes are stored under files/<uuid>.<ext> (UUID, not the remote filename) and rendered in <img> with Svelte-escaped titles, so SVG scripts do not execute in the app.
• The fetch runs in the user’s browser and is CORS-constrained; downloaded bytes stay in that user’s remoteStorage. No new dependencies.
