Closes the loop on the "Metric Pressure_Sys" leak Marc reported on
the Einschätzungen surface 2026-05-14. The stripChartTokens regex
extension cleans up render-time output, but the model was free to
keep emitting raw enum identifiers turn after turn. This commit
teaches the generator to stop emitting them in the first place.
Insight-generator (DE + EN) gets GROUND RULE 13:
- Lists every banned identifier verbatim — Pressure_Sys,
BLOOD_PRESSURE_SYS, PULSE_BPM, MOOD_SCORE,
MEDICATION_COMPLIANCE_PCT, plus the v1.4.23 Apple Health surface
(HEART_RATE_VARIABILITY, RESTING_HEART_RATE,
ACTIVE_ENERGY_BURNED, FLIGHTS_CLIMBED,
WALKING_RUNNING_DISTANCE, VO2_MAX, BODY_TEMPERATURE,
SLEEP_DURATION).
- Enumerates the exact user-facing fields the ban applies to —
summary, recommendations[].text, findings, dailyBriefing,
trendAnnotations.*, weeklyReport.*, storyboardAnnotations.
- Carves out the contract identifiers the parser reads
(metricSource.type, sourceMetric, trendAnnotations keys) so the
JSON contract stays intact — the ban applies ONLY to prose.
- Documents the natural-language labels to use instead ("your
systolic", "your weight", "your medication adherence", …).
Coach system-prompt (DE + EN) gets the matching GROUND RULE 8 with
the same banned list, the same prose-only carve-out, and an extra
clarification that evidence-block labels stay human-readable
("avg30 systolic", NOT "BLOOD_PRESSURE_SYS_AVG_30") while the
window slot keeps its documented contract vocabulary.
PROMPT_VERSION 4.23.0 → 4.24.0. The rule is genuinely new (neither
prompt previously mentioned the enum identifiers in any form), so
the bump reflects the additive behavioural change. Existing pin
assertions in coach-prompt-v423.test.ts + coach/system-prompt.test.ts
loosen from `/^4\.23\.\d+$/` to `4.{>=23}.x` so future additive
ratchets don't force a hostile test rewrite each time.
New unit tests pin GROUND RULE 13 + 8 by the banned-identifier
strings + the contract-carve-out wording so a future copy-paste
regression can't silently drop either rule.
