## GET /api/solutions

List solutions.

**Query parameters**

- `limit` (optional): Page size (1–100, default 100).
- `after` (optional): Keyset cursor — return the page after this row (next page).
- `before` (optional): Keyset cursor — return the page before this row (prev page).
- `ids` (optional): Comma-separated list of IDs. Narrows results to these IDs within the caller's accessible scope (does not bypass access checks).
- `filter` (optional): Nested filter expression (`<Entity>Filter`): AND/OR/NOT + per-field comparison operators + relation traversal. JSON-encoded on the query string.
- `orderBy` (optional): Multi-key sort (`<Entity>OrderBy[]`): array of `{ field: direction }` applied in order. Directions: asc/desc plus the four explicit nulls variants. JSON-encoded on the query string.
- `workspace_id` (optional): Filter to solutions in this workspace. When omitted, returns solutions across every workspace the caller is a member of (admins see all).
- `member_entity_id` (optional): Filter to solutions that contain this entity as a member. Powers 'what solutions is this agent part of?'.
- `include_deleted` (optional): Soft-deleted solution visibility. `false` (default) — active rows only. `true` — active plus soft-deleted. `only` — soft-deleted only (trash view).
- `name` (optional): Case-insensitive substring match on name.
- `created_by` (optional): Shorthand: filter where `createdBy` equals this value.
- `retention_tier` (optional): Shorthand: filter where `retentionTier` equals this value.
