Add Blink App Support for Android

This module adds support for 4 Blink artifacts:

• Camera Information
• Camera Entitlements
• Syncmodule Information
• Syncmodule Entitlements

All artifacts are present in the BlinkRoom database.

Test Device

This data was collected from a Samsung SM-A166U (A16 5G) running Android 16 with the 2025-10-01 security patch.

• Ran the tool against a real extraction and confirmed the row counts, not just that it imports.
• Ran python admin/scripts/check_artifact_output.py <report folder> on that report and fixed or documented every finding. An empty or constant column is often a real result (no group chats, coarse location denied); the fix for those is to say so in the artifact's notes, which is also what stops the checker reporting them.
  --Syncmodule Entitlements holds constant values on 4 columns. This is expected.
• Checked it against a second app data directory (a second Android user, or two iOS containers). --compare <multi-container report> reads the scaling for you: it should be exactly double.
• notes, description and sample_data say only what the data shows, and the numbers were re-derived from the finished run.

Anything reviewers should know

I cancelled the original PR for this app because it was poorly done. And this is my first PR and I am a git newcomer.

Thanks for the contribution!

This PR changes artifact modules without test data for them. A small fixture with each artifact change lets reviewers run the module against real data, and the committed case keeps guarding the module after merge.

• BlinkApp.py: please include a fixture with this PR.

Adding a fixture

Generate it from your extraction with the helper (details in create_module_test_cases.md):

python admin/test/scripts/make_test_data.py <module> --case <case_number> --input <extraction.zip>

It writes admin/test/cases/testdata.<module>.json and one zip per artifact under admin/test/cases/data/<module>/.

Size rules:

• Under 10 MB per zip: commit the files in this PR.
• 10 to 25 MB: commit the case JSON in the PR and attach the zip to a comment here.
• Over 25 MB: say so here and a maintainer will arrange a handoff.

If your extraction cannot be shared:

• If the app appears on a public research image, generate the fixture from that instead. public_corpus_images.md lists the images and where to download them.
• Or sanitize the real file in place: keep the file the app wrote and overwrite only the personal values, which keeps the format honest.
• Or script a known session: install the app on a test device with a throwaway account, perform documented actions, and extract that.

If none of those fit, say so here and we will work it out. The PR can still be reviewed and merged with the gap recorded in the artifact's notes.

This is a request, not a gate. Nothing here blocks review.

I may be able to use the helper. Let me verify there is no sensitive data. If that isn't possible, I will likely make a copy and sanitize the real db file. Thanks!

[frahmco]

I edited data that was sensitive from the original BlinkRoom db file, nothing is particularly identifying but just to be cautious. I've attached it here, it is not very large.

I hope to eventually get my hands on some Blink cameras to be able to control actual tests, there's much more data that could be gleaned from the app, I just don't have a way of testing without cameras to connect. Thank you for your time!
