Solid-color members phash-collapse to distance 0, so the second archive's member
deduped away ("held no supported members") and members_imported was 0. Use
structurally distinct patterned jpegs so both members import — the resume cursor
mechanics were already correct.

reextract_archive_attachments loaded ALL PostAttachments and ran in one pass up
to a 30-min soft limit, then died without re-enqueueing — a large archive
backlog would only ever partially process. And a naive re-run can't advance: an
already-extracted archive is still an archive on disk, so it'd re-extract the
same first batch forever.
Give it a real cursor + time-box + self-resume (mirrors normalize_tags_task,
operator-asked 2026-06-07: reasonable timeout, then re-queue so other work keeps
flowing):
- service scans attachments with id > after_id in ascending order, time-boxes
the chunk, and reports partial=True + resume_after_id (last scanned id).
- task passes a 600s budget and re-enqueues itself from the cursor until the
scan is exhausted. Routes on the maintenance_long lane.
- This is independent of the maintenance_long lane isolation (already shipped) —
that stops long tasks starving the quick maintenance queue; this stops the
re-extract itself dying on a big backlog.

Existing PostAttachments that are actually archives (filed opaquely before the
magic-byte gate) need extracting retroactively. cleanup_service.
reextract_archive_attachments scans PostAttachments, magic-detects the archives,
and for each reconstructs the post's sidecar from the DB + re-runs attach_in_place
in a temp dir — so the members extract and re-link to the SAME post via
find_or_create_post (source_id + external_post_id). Idempotent (members dedupe by
sha256). Enqueues thumbnail+ML for new members.
Wired as a maintenance-queue Celery task (tasks/admin) + POST
/api/admin/maintenance/reextract-archives (202) + a "Re-extract archive
attachments" card in Settings → Maintenance.
Test: a zip stored under a mangled extension-less name extracts + links its
member to the post via ImageProvenance, and a second run is a no-op (idempotent).
