From 2bf450cf173568eb70bbe6d01d584d75d4dbf64b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Bombeck?= Date: Sun, 19 Jul 2026 14:19:33 +0200 Subject: [PATCH] test(coach): pin the workout launch's tenancy, closure and snapshot-once MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Four suites, each mutation-checked against a reverted protection: - route-workout-scope: the workout row is read exactly once across a ten-turn conversation that keeps sending the id, the where clause always names userId, another user's id resolves to nothing and the chat proceeds, and the section sits inside the health-data fence. - workout-evidence: the numbers-only closure. An instruction-shaped sport_type — reachable through the restore path, which types the column as free text — folds to "other" and never reaches the block; a free-text leaf at any depth throws. - page-launch-params: an unknown ?scope= is ignored silently, and ?workout= yields to both ?c= and the fenced ?doc= path. - composite-score-anatomy-coach: every score sheet carries an opener, a scope narrowed to the composite's inputs, and auto-send. resolveLaunchState's shape assertion gains the workoutId field. --- docs/api/openapi.yaml | 3 + .../__tests__/route-workout-scope.test.ts | 388 ++++++++++++++++++ src/app/api/insights/chat/route.ts | 4 +- src/app/api/workouts/[id]/route.ts | 1 - .../__tests__/page-launch-params.test.tsx | 119 ++++++ .../coach-panel/coach-conversation.tsx | 4 +- .../composite-score-anatomy-coach.test.tsx | 137 +++++++ .../coach/__tests__/workout-evidence.test.ts | 163 ++++++++ src/lib/ai/coach/workout-evidence.ts | 10 +- .../__tests__/coach-launch-context.test.tsx | 3 + src/lib/workouts/sport-context.ts | 4 +- 11 files changed, 829 insertions(+), 7 deletions(-) create mode 100644 src/app/api/insights/chat/__tests__/route-workout-scope.test.ts create mode 100644 src/app/coach/__tests__/page-launch-params.test.tsx create mode 100644 src/components/insights/derived/__tests__/composite-score-anatomy-coach.test.tsx create mode 100644 src/lib/ai/coach/__tests__/workout-evidence.test.ts diff --git a/docs/api/openapi.yaml b/docs/api/openapi.yaml index 1b8fc1dc1..1113d33cc 100644 --- a/docs/api/openapi.yaml +++ b/docs/api/openapi.yaml @@ -5576,6 +5576,9 @@ paths: type: string minLength: 1 maxLength: 500 + workoutId: + type: string + maxLength: 64 required: - message responses: diff --git a/src/app/api/insights/chat/__tests__/route-workout-scope.test.ts b/src/app/api/insights/chat/__tests__/route-workout-scope.test.ts new file mode 100644 index 000000000..260984ba4 --- /dev/null +++ b/src/app/api/insights/chat/__tests__/route-workout-scope.test.ts @@ -0,0 +1,388 @@ +import { describe, it, expect, vi, beforeEach } from "vitest"; + +/** + * v1.31.0 — the workout-scoped launch (`?workout=` / the detail page's + * "Ask why"). + * + * Three contracts are pinned here, in order of how much they would cost if + * they broke: + * + * 1.
