Add Chrome sync synced tabs and session devices - #1311
Merged
Conversation
Two artifacts from the Chrome sync LevelDB store nothing read before: the pages held in synced tabs, with the address, page title, visit time and HTTP status, and the devices that synced a session to the profile. Sync carries sessions from the other devices signed into the same profile, so the tables name laptops and desktops alongside the phone and attribute each tab to the device that synced it. Field numbers are Chromium's, from session_specifics.proto and tab_navigation.proto. Storage view mirrors are collapsed before the store is opened and a navigation entry that repeats unchanged across superseded copies is reported once. sample_data measured on 23 Android corpora.

Re-running the measurement script inserted a second sample_data key into each artifact, which pylint caught as a duplicate key. Each artifact now carries one block, holding the same measured counts. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Two artifacts from the Chrome sync LevelDB store that nothing reads today.
Sync carries sessions from the other devices signed into the same profile, so these tables name laptops and desktops alongside the phone, and every tab row carries the device name it was synced from. Measured on 23 Android corpora: 2,551 tab rows and 28 device rows across 15 of them.
Field numbers are Chromium's, from components/sync/protocol/session_specifics.proto and components/sync/protocol/tab_navigation.proto. The mirrored Android storage views of a store are collapsed before it is opened, and a navigation entry that repeats unchanged across superseded copies is reported once, which took one image from 890 rows to 162 without losing an entry. A window field that held no value or -1 on every tested record is not reported, and the notes say so.
