| 4 | + * `DatasourceSchema.name` refuses the route-shadowed names (#29308). |
| 5 | + * |
| 6 | + * ## What was wrong |
| 7 | + * |
| 8 | + * The datasource admin API mounts the driver catalog at |
| 9 | + * `GET /api/v1/datasources/drivers`, ahead of `GET /api/v1/datasources/:name`, |
| 10 | + * so a datasource named `drivers` can never be read by name. The admin create |
| 11 | + * door refused it, but `DatasourceSchema.name` accepted it, so the same |
| 12 | + * unreachable name was minted from code (`defineStack`) or through the |
| 13 | + * metadata save door (`PUT /api/v1/meta/datasource/drivers`). |
| 14 | + * |
| 15 | + * ## What is pinned |
| 16 | + * |
| 17 | + * - the reserved set is ONE exported constant, frozen, whose entries are |
| 18 | + * identifiers the `name` pattern accepts (so the refusal pattern built from |
| 19 | + * them needs no escaping); |
| 20 | + * - `DatasourceSchema` refuses every entry: one issue at `name`, an |
| 21 | + * `invalid_format` whose message names the name and the shadowing route, |
| 22 | + * and carries no tracker number; |
| 23 | + * - `defineStack` (the code door) refuses it with the ADR-0112 envelope at |
| 24 | + * `datasources.0.name`; |
| 25 | + * - the published JSON Schema carries the refusal (a second `pattern`), so a |
| 26 | + * JSON-Schema consumer refuses the name too; |
| 27 | + * - CONTROLS: near names (`driver`, `drivers_archive`, `my_drivers`), the |
| 28 | + * host's `default` row and `test` (a literal that shadows no by-name read) |
| 29 | + * still parse. |
| 30 | + * |
| 31 | + * The admin door's half (the registrar mounts the literal from this list, and |
| 32 | + * the create door refuses it) is pinned in |
| 33 | + * `packages/services/service-datasource/src/__tests__/datasource-route-reserved-names.test.ts`. |
