Source-string analysis showed the Hypertonie miss is not a bug but a
structural consequence of embedding whole noisy Anamnese paragraphs
against terse Alpha-ID corpus strings. Resolution (user-decided): the
caller (doctate's LLM) extracts diagnostic phrases; this project still
contains no LLM — it just receives a cleaner input contract.
Spec: new §1a (rationale + generous extraction contract + the honest
extractor-is-recall-bottleneck trade-off); §1/§2/§3/§6/§8/§9/status
updated; §6 reworks eval (representativeness shift, paraphrase axis,
hand-labeled phrase-list set, separated extraction-ceiling vs matcher
recall). Plan: Goal/Architecture, revision banner, Task 6 rewritten
(one non-empty line = one unit; split_segments name/fields retained,
minimal-churn decision), Task 11/19 revision notes.
Code not yet changed (segment.rs still blank-line splits) — next step.
