The retrain in #258 took the aroma roster 164 β†’ 167, which moved three numbers quoted in nineteen places β€” README, five docs, the workbench UI, the MCP server, the e2e conftest, and the pipeline comments in predict.py/app.py.

Several were already stale before this: the profile vector had been described as 170-dimensional since before mouthfeel shipped, and one workbench card claimed 167 heads in its title while still saying "164 survive" in its body.

The three canonical numbers, stated once so future drift is easy to spot:

190 trained heads in all 6 taste + 167 aroma + 5 mouthfeel + 12 safety
178 dimensions in the flavor-profile vector taste + aroma + mouthfeel β€” tox deliberately excluded, safety isn't a flavor-match dimension
167 aroma descriptor heads clearing CV-AUROC β‰₯ 0.70

The loader reports 191 artifacts: the 190 heads plus the sweetness-intensity regressor, which is a regressor rather than a head and so isn't counted as one.

Also corrects the aroma corpus size in AROMA.md β€” still read 1,994 molecules against an actual 2,403 after the supplement work.

Verified live against the running app after restart: /api/heads returns 6 + 167 + 5 + 12 = 190, and blackberry/fig/magnolia are serving.

The retrain in #258 took the aroma roster from 164 to 167, which moved three numbers that were
quoted in nineteen places across the README, five docs, the workbench UI, the MCP server, the
e2e conftest and the pipeline comments in predict.py and app.py. Several were already stale
before this β€” the profile vector had been described as 170-dimensional since before mouthfeel
shipped, and one workbench card claimed 167 heads in its title while still saying 164 survive
in its body.

The three canonical numbers, so future drift is easy to spot:

  190  trained heads in all β€” 6 taste + 167 aroma + 5 mouthfeel + 12 safety
  178  dimensions in the flavor-profile vector β€” taste + aroma + mouthfeel, tox deliberately
       excluded because safety is not a flavor-match dimension
  167  aroma descriptor heads clearing CV-AUROC >= 0.70

(The loader reports 191 artifacts: the 190 heads plus the sweetness-intensity regressor, which
is a regressor rather than a head and so is not counted as one.)

Also corrects the aroma training corpus size in AROMA.md, which still read 1994 molecules
against an actual 2403 after the supplement work.
