# External evidence (2026-09-29)

Independent-source media used to stress the identity pipeline. **None of this is
Tier 2.** DECISION.md's Tier 2 is a second labelled store visit; these are
`external_proxy` artifacts, and every manifest here says so.

| Directory | What it holds |
|---|---|
| `other-mayo/` | 8 accepted images for `sku_l04`, `sku_l07`, `sku_l09` from 6 source domains, plus the scored result |
| `l12-reconciliation/` | What `sku_l12` actually is, from the shelf tag and package pixels |
| `kewpie/` | Kewpie 450 g research (the near-unknown case) |
| `tier3-sources/` | Two reusable pan clips and 11 rejected candidates for a future Tier-3 replay |

## Leak test

Every accepted image was template-matched against `add/image6.jpg`. Highest
score across all 8 is 0.675 (`sku_l07_1`), and the 0.95+ band that identifies a
crop of the evaluation photo is empty. The images are genuinely external.

## Result: 8 images, 0 false accepts

Scored through the shipped `LocalLaneAdapter` + `DecisionPolicy` against
`stock-lopia-clean` (`other-mayo/eval_result.json`):

| Verdict | Count | Files |
|---|---|---|
| Correct accept | 4 | `sku_l07_1`, `sku_l07_2`, `sku_l09_1`, `sku_l09_2` |
| Abstain | 4 | all `sku_l04_*` |
| False accept | **0** | — |

Two things this establishes that the image6 shelf cannot:

- **`sku_l07` is answered with no enrolled image.** Both l07 images accept
  through the text lane alone: `sku_l07_1` reads ラッキー フヨネーズ, and
  `sku_l07_2` reads the rear label's 製造者：丸和油脂株式会社 with 内容量：200g.
  The catalog row is 丸和油脂 ラッキーマヨネーズ 200g, so the manufacturer and
  the size together name it. This is the text lane's coverage claim - that a
  product with no reference image can still be named - holding on data that was
  not used to build it.
- **The l04 abstentions are correct behaviour, not a miss.** l04 has no
  enrolled image either, and its reads are weak: `sku_l04_2` reads only
  コと旨 タ 味 (all rows score 0.0), and `sku_l04_4` reads the rear label with
  やまや garbled to まや, scoring 0.379 - below the accept line. Abstaining on
  a weak read is the designed outcome.

`sku_l07_2` accepts with a negative local score (-0.55) on text evidence alone.
That is the lane doing its job, but it is worth naming: the accept rests on two
matched tokens (manufacturer + size), not on geometry.

## What is still missing

No external source gives per-SKU identity for the whole catalog, and no
reusable clip combines the target category with shelf-distance text
resolution. The Tier-2 and Tier-3 gates in DECISION.md still need the
operator's own recorded walks.
