Executes the 2026-07-05 product decision (FC downloaders = art-dedicated
services only), which removed Twitter/X and Bluesky but left deviantart
fully wired for seven weeks — the half-retired state rule 22 exists to
prevent.
Removed: the PlatformInfo module and its registry entry, the gallery-dl
extractor block, extension_service's artist-page pattern, the extension's
PLATFORMS + PLATFORM_ARTIST_PATTERNS entries, its manifest host permission
and content-script match, the frontend icon/colour/label, and the operator-
facing "supported platforms" list that still advertised it.
Two judgment calls, both recorded in migration 0088:
* existing `source` rows are DISABLED, not deleted. The row is the only
record of the artist's DeviantArt URL. Disabling is also required for
correctness rather than tidiness: with the platform unregistered the
download path falls through to gallery-dl, which carries its OWN
deviantart extractor, so an enabled row would have kept downloading
from a dropped platform.
* the `credential` row IS deleted — a live session cookie for a site FC
will never call again.
Adds the invariant whose absence is why manifest.json drifted in the first
place: nothing tied its domain lists back to the platform table. The
extension suite now asserts both directions, plus that no host permission
belongs to an unclaimed domain (`*://*/*` exempted — FC is self-hosted at
an operator-chosen URL the extension cannot enumerate).
Extension version 1.0.10 -> 1.0.11: ci.yml's guard hard-fails a packaged
extension change without a bump. No release is cut — build.yml's
sign-extension job only runs on main.

test_artist_directory_service._seed_image built sha256 from
abs(hash(suffix)) % 10000 — PYTHONHASHSEED-randomized hash() over only 10k
buckets, so two suffixes in one test could birthday-collide and violate
uq_image_record_sha256. Flaky per process seed: passed on dev (run 1179),
failed on main (run 1182) with identical code. Use
hashlib.sha256(suffix).hexdigest() for a stable, collision-free digest.
