From 3f60c81b9e08c22a85a3361f44b28b5aee743de8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Bombeck?= Date: Mon, 11 May 2026 01:35:45 +0200 Subject: [PATCH] feat(coach): per-user prompt-tuning surface (settings cog returns) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The v1.4.22 B5 audit removed the placeholder cog from the Coach drawer header because it had no real wiring. v1.4.23 H4 returns the cog with an actual settings surface backed by a per-user preferences row. Schema: nullable JSONB column `users.coach_prefs_json` (migration 0038_coach_prefs). Null = legacy v1.4.22 defaults; non-null carries `{ tone, verbosity, excludeMetrics, showEvidenceByDefault }` validated by the Zod schema in `src/lib/validations/coach-prefs.ts`. Routes: GET + PUT `/api/auth/me/coach-prefs`. PUT validates the body, persists the canonical defaulted form, and emits an `auth.me.coach-prefs.put` annotation with the four-knob meta. OpenAPI registry covers both verbs; the spec regenerates without drift. Coach prompt builder: `getCoachSystemPrompt(locale, prefs)` prepends a per-user OVERRIDE paragraph for non-default tone (neutral / concise) and verbosity (brief / detailed). Concise tone forces brief verbosity regardless of the explicit selection — concise == short. Default prefs leave the prompt unchanged so the v1.4.22 train stays in place. Snapshot builder: reads the prefs row BEFORE any measurement query and intersects `excludeMetrics` with the resolved scope. The model never sees data the user opted out of — that's the load-bearing order: filter first, query second. UI: settings cog in the drawer header opens a right-edge `` with three Select pickers (tone, verbosity) and one Switch column (per-metric exclusions + showEvidenceByDefault). Save calls the PUT route and invalidates the `["coach-prefs"]` query so the next reply honours the new defaults without a reload. EN + DE i18n keys for every label and hint. Message-thread reads the same `["coach-prefs"]` cache and toggles the `open` attribute on the evidence `
` element when `showEvidenceByDefault` is true. Tests +24 unit (coach-prefs schema, system-prompt prefix, snapshot mock for new prefs row). Integration round-trip seeds a session, PUTs a non-default prefs shape, asserts the GET reflects the saved values + the DB row carries the canonical defaulted form.
