kiyo9w 07de2bd37d fix(identity): calibrate both accept lines against unrelated shelves
The gates were tuned on image6 alone, where every crop is a facing of a product
the shelf actually holds. Wikimedia supermarket photos of milk, soy and snack
shelves share nothing with the LOPIA catalog, so every accept there is a false
accept by construction - and at the old lines there were 83 of them.

Text lane: TEXT_MIN_SHARED 2 -> 4. The vocabulary filter drops bigrams no name
contains, so a short garbage read can end up with a perfect ratio on two
coincidental pairs. 20 of 26 text-lane answers on those shelves rested on
exactly two: '避くて おいしい' named sku_l12 through おい/いし.

Local lane: LOCAL_ACCEPT 2.0 -> 4.0. The residual accepts were geometric
matches with no text overlap at all, scoring 2.26-4.81.

Measured, 2297 distractor crops and 109 image6 facings:
  accept  floor   image6 shown/correct   precision   false accepts
  2.0     2       54 / 49                90.7%       83 (3.61%)
  2.0     4       52 / 48                92.3%       30 (1.31%)
  4.0     4       44 / 42                95.5%        8 (0.35%)
  5.0     6       36 / 36               100.0%        0 (0.00%)

4.0/4 is the only region passing both G2 (>=95% precision) and G3 (<=1%
far-unknown) with coverage left. On the shipped evaluator: 66% end-to-end at
95% precision, 2 false accepts, against 77%/91%/5 before.

The two tests that pinned the old floors now pin the new ones, with the reads
that separate them.
