Positive completed reps are required for records; less assistance wins and zero remains valid. Assistance does not contribute to lifted-load volume, maxWeight, or estimated 1RM. Requires the workout_sessions:write scope. This operation maps to /app/v1/workout/performance/sessions/:sessionId/exercises and retains its Workout V2 permission, feature-flag, and resource-scope checks. The clientId path parameter is resolved inside the company bound to the Public API token when present. ## OpenAPI ````yaml /openapi/public-v1.json post /public/v1/workout/performance/sessions/{sessionId}/exercises openapi: 3.1.0 info: title: FITsociety Public API v1 version: 1.0.0 description: >- Developer Public API endpoints under `/public/v1`.

It is a FALLBACK, not an override: the coach's `repsPlaceholderCoach` wins wherever it exists, so this value is only used for sets the coach never prescribed (per-set tracking off, extra sets, metrics left blank). Sending it for a prescribed set is accepted but has no effect. **Never logged work**: placeholders are excluded from every total, volume, PR and completion check, so leaving a hint after clearing a value does not make the set count. To COMMIT a hint the athlete accepted, send it as the real `reps` value with `completed: true` — but never submit a RANGE on a completed set, which is stored as its minimum (`"12-24"` → 12) and under-credits the athlete. weightPlaceholder: type: - number - 'null' minimum: 0 example: 30 description: >- The client's own hint for an empty weight input.

A range string (`"8-12"`) is allowed. It is a FALLBACK, not an override: the coach's `repsPlaceholderCoach` wins wherever it exists, so this value is only used for sets the coach never prescribed (per-set tracking off, extra sets, metrics left blank). Sending it for a prescribed set is accepted but has no effect. **Never logged work**: placeholders are excluded from every total, volume, PR and completion check, so leaving a hint after clearing a value does not make the set count. To COMMIT a hint the athlete accepted, send it as the real `reps` value with `completed: true` — but never submit a RANGE on a completed set, which is stored as its minimum (`"12-24"` → 12) and under-credits the athlete. weightPlaceholder: type: - number - 'null' minimum: 0 example: 30 description: >- The client's own hint for an empty weight input.
