Registering `ko` in the `Locale` union left seven locale-keyed tables
without an entry, so the build could not type-check and the safety
screens, the citation-coverage grader and the reference-range parser
read nothing at all for a Korean reader.
Three failures were not missing keys but wrong assumptions:
- The shared fold decomposes with NFD and strips U+0300-U+036F. Latin
accents become plain letters, but Hangul decomposes into jamo, which
are not in that range and survived — so folded Korean text was a jamo
sequence no precomposed table entry could ever match. It recomposes to
NFC now; every Latin, Polish and German fold is byte-identical.
- `normaliseLabKey` kept `[a-z0-9]`, which reduced every Korean analyte
name to the empty string, so the derived index held none of them and a
Korean cholesterol result reached a FHIR export uncoded.
- The reference-range parser had the hyphen and the dashes but not the
tilde a Korean lab actually prints (`3.5~5.0`).
The Korean safety banks carry no `\b` next to a Hangul token — `\b` is
an ASCII `\w` boundary and Hangul is not `\w`, so `/\b증량/` matches
nothing — and the clause order is the mirror of the Latin banks, since
Korean closes with the verb. The dose patterns require a target-marking
particle for the same reason the Latin banks require "to"/"by": without
it the permitted restatement "7.5mg을 복용 중이고, 체중은 내려가고
있어요" tripped the lowering pattern.
The Coach and Insights prompts route `ko` down the reviewed English body
plus a Korean reply directive; there is no `safety-contracts.ko.yaml`, so
the native builder has no Korean ground rules to compose from.
The normative-claim bank held English and German words. Insight
recommendations are generated in the reader's locale, so for French,
Spanish, Italian and Polish every recommendation scored non-normative:
the annotation reported zero normative claims and zero uncited ones, and
the admin quality dashboard read that as full coverage rather than as no
measurement at all. A check that cannot fail is indistinguishable from a
check that passes.
The bank now has one arm per shipped locale and the caller passes the
generation locale; the reader's arm and the English one both run, because
a fallback provider answers a non-English reader in English. Matching
folds both sides through the shared label fold and anchors the leading
word boundary, so inflections still hit while the everyday Italian
"soprattutto" no longer counts as a comparative.
These words are the model's prose, not app labels, so they are not in the
message bundles and cannot be derived from them. The structural test
refuses an empty arm instead: a seventh language fails the suite rather
than quietly scoring nothing. An empty arm also used to compile to an
alternation that matched every string, which would have flipped the same
blindness to the opposite extreme.
generateInsight() parsed against the strict aiInsightResponseSchema,
cross-checked that every recommendation's metricSource appeared in
citations[], and threw InsightSchemaError on a second failure. Its only
caller was runWithFallback(), which had no production caller — every
live surface runs runRawCompletionWithFallback. So none of it executed.
Wiring it into the live path was the alternative and it is not viable:
the live insightResultSchema has no citations[] field at all and treats
metricSource as optional, so the cross-check would have rejected
essentially every generation rather than tightening anything.
Removed: runWithFallback and its param/result types, generateInsight
and its private helpers, findUncitedRecommendations,
findRecommendationsMissingRationale, the never-thrown InsightSchemaError
and the isHardProviderFailure branch that excluded it, and
computeConfidence — a deterministic override that only ran inside the
dead wrapper.
Kept: buildRetryCorrectionMessage, which comprehensive-generate sends on
its own retry leg; the file it lived in is renamed to match what it now
holds. aiInsightResponseSchema stays as the shape that message
describes. Note the retry prompt asks for a stricter payload than the
live validator requires — that mismatch predates this and is left alone.
computeCitationCoverage is untouched and still live: it is a metric, not
a gate, and v1.30.24 wired it into the comprehensive post-parse step.
Chain-runner coverage the deleted tests carried (last-working cache,
empty-input guard) is ported onto runRawCompletionWithFallback, which
shares the machinery.
The coverage check hung off generateInsight, whose only caller runWithFallback
has no production caller left -- every live surface routes through
runRawCompletionWithFallback instead. The admin quality dashboard was reading a
metric nothing emitted. Widen the input to the structural shape both payloads
share and call it from the comprehensive post-parse step, so the annotation
reflects real generations.
Writing the locale tests found three gaps the English-only banks hid: Polish
verb suffixes fell outside the ASCII word class, a trailing word boundary after
an accented character never closed, and German subordinate clauses put the verb
last so the natural phrasing of a dose instruction never matched. The payload
collector also skipped legacy bare-string recommendations entirely.
After the schema parse and citation cross-check pass, the wrapper
counts how many recommendations make a normative claim ("target",
"should", "normal range", "above", "below") and how many of those
carry a `referenceId` pointing into the curated medical-reference
bundle. The result lands in the active Wide-Event meta annotation
under `ai_total_recommendations`,
`ai_normative_recommendations`,
`ai_cited_normative_recommendations` and
`ai_uncited_normative_recommendation_ids` so the admin AI quality
dashboard can chart citation-coverage over time.
Observational only in v1.4.16 — a normative rec without a referenceId
is logged, never raised as a parse error. Phase B5c will flip the
check to required for severity >= "important".
15 unit tests pin the keyword heuristic (EN + DE), the coverage
counts across cited / uncited / observational mixes, and the
`generateInsight()` integration that emits the annotation only on
success (skipped on schema-failure throw).
