Changelog

Description

This release is the fourth leg of the media hash-scanning rollout (versions 2.0.2030–2.0.2037; user_index, storage_index and storage_bucket already released). It adds the worker-facing side of the media scan pipeline to the local user indexes: a media scan job log and endpoints from which registered scanner principals fetch jobs and submit verdicts. All of it is gated on the media scan configuration held by the user_index, which is set by a separate dual-authorized platform-operator action that will only be taken once the full train is released - media scanning remains switched off.

The local user index also now watches its own pipeline health: if scan jobs are queued but no verdicts are arriving, it reports the stall to the user_index (which posts a notice to the internal moderation channel), with an all-clear on recovery.

This release also removes message media from the OpenAI moderation request payload - classification is text-only. This is one of the preconditions, recorded on #9149, for ever enabling the text classifier.

This leg must precede the community and group releases later in the train, which send media scan requests to the local user index.

Added

• Add the media scan job log plus worker-facing media_scan_jobs and submit_media_scan_verdicts endpoints, gated on the media scan config set by the user_index (#9161)
• Detect a stalled media scan pipeline (jobs queued but no verdicts arriving) and raise it in the internal moderation channel via the user_index, with an all-clear on recovery (#9161)

Changed

• Never send message media to the OpenAI moderation API - classification is text-only (#9149)

Fixed

• Fix detection of when to retry c2c calls (#9106)
