Per-tick drain (backfill_utc_dates) at the existing date-drain seam, inside the per-library online gate. Selects date_utc IS NULL AND date_taken IS NOT NULL (new partial index idx_image_exif_utc_backfill), re-runs resolve_dates_batch with empty priors (one exiftool subprocess per batch, same call shape as the #117 audit), and writes only the new-contract triple; the legacy pair stays frozen. Capped by DATE_BACKFILL_MAX_PER_TICK; missing-file rows are paged past without spending the cap. Legacy manual overrides convert via manual_date_resolution rather than being re-resolved from the file. Day-boundary invalidation deletes the day-span precomputed reels covering a re-dated row's old/new display-zone month-day so the nightly pre-gen regenerates them. Progress: imageserver_date_backfill_remaining gauge + date_backfill_remaining on GET /libraries. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

-- Partial index backing the true-instant backfill drain (ADR-0001, ticket
|
|
-- #118). The drain selects rows still on the legacy convention
|
|
-- (`date_utc IS NULL`) per library in id order, and the progress surface
|
|
-- (Prometheus `imageserver_date_backfill_remaining` + `/libraries`) counts
|
|
-- the same set. Mirrors `idx_image_exif_date_backfill`: the index shrinks
|
|
-- to nothing as the drain converges, so it costs ~0 after cutover.
