The engine owns the OCR backend, a shared OCR lock and a dedicated tag worker, so
a tag pass can never occupy a classification worker or slow a frame. A live
session plans rail bands on the frame loop (cheap), runs them on that worker, and
attaches whatever the cache already knows; a still runs one synchronous pass.
Tracks and detections now carry price_tag and reconciliation, and the summary
carries price_tags plus compliance. Config can turn tags off per session.
Compliance now fails closed on evidence quality. The first real run produced 106
"missing tag" violations on a shelf where only 8 tags were readable - our tag
*detection* was incomplete, not the shelf. A row is only judged when at least
half its facings carry tag evidence; otherwise it reports "tags detected for 14
of 91 facings in this row" as a hint. Missing-tag findings are one per row with a
count, not one per facing, and price_mismatch still reports every disagreement.
On add/image6.jpg the result is now 7 real price mismatches and no false
violations.

test_live: a product is unconfirmed, then labelled, without blocking frames; a
weak match never names a SKU and ends as needs_confirmation; a restarted id is
re-verified rather than inheriting its old label; inherited labels are flagged;
latest-frame-wins accounting; payload shape; glare hint; per-session
classification cap; a method change clears labels and drops late results.
test_api: health, catalog shape (no local paths), template-image 404s including
traversal-looking ids, stock validation, recognize over raw bytes and multipart,
415/422/400 with one error shape, classify/inspect roundtrip, IMAGE_EXPIRED,
token auth on REST and the socket, the WebSocket protocol (hello, frames,
config/reset/ping, recoverable BAD_FRAME and UNDECODABLE_IMAGE, inspect and
TRACK_NOT_IN_VIEW), the session limit, and the legacy session route.
Server fixes the tests forced out: FastAPI validation errors now use the same
{"error": {...}} envelope as every other failure, and the legacy session routes
accept a missing JSON body instead of returning 500.
