From 7921ffc8e6f1f25a78eba3708390b4877b0a5e96 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Bombeck?= Date: Sun, 10 May 2026 19:20:50 +0200 Subject: [PATCH 1/8] fix(insights): wire generate route to strict prompt so dailyBriefing emits MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The /api/insights/generate route was still calling the legacy getInsightsSystemPrompt that returns the v1.4.5 {changed, stable, drivers, …} shape and never asks the model for a dailyBriefing block. GROUND RULE 8 (emit dailyBriefing when the snapshot has signal) lives on getStrictInsightsSystemPrompt in src/lib/ai/prompts/insight- generator.ts; the route never adopted it. Re-runs from the hero strip therefore stored a payload with no briefing, the use-insights-advisor lift saw null, and the briefing card painted its empty state forever. Switch the route to getStrictInsightsSystemPrompt(locale). Existing strict-shape tolerance is unchanged: insightResultSchema.safeParse falls through to the raw parsed body on shape mismatch, and aiInsightResponseSchema's passthrough() keeps any custom keys for forward compat.

A turn that asked "why was BP higher on Monday?" had no day-level rows to ground in and the model fell back to apologetic aggregate-only phrasing ("from the snapshot I cannot isolate the specific Monday"). Extend buildCoachSnapshot to fold in: - timeline.recent: one row per UTC day for the last 14 days, each tagged with its weekday so the model can answer day or weekday questions directly. BP rows pair systolic + diastolic; days with only one side measured are dropped to avoid fabricating a complement. - timeline.weekly: ISO-week buckets covering days 15..N where N is the configured window. Keeps the prompt budget tight on 30/90-day windows while still letting the Coach cite older weeks. - per-day medication adherence rows from MedicationIntakeEvent so the Coach can answer "did I miss my dose Tuesday?" without inventing the schedule. Also add the optional `scope` field to coachChatRequestSchema (sources + window) so the upcoming sources-rail picker can narrow the snapshot without breaking older clients — missing fields fall through to all-source last30days. A typical 30-day, 5-source snapshot lands around 2.4-2.8 KB JSON (≈700-900 prompt tokens) — comfortably inside the 25k/day Coach token budget.
