| 1 | """U2: backend-chain descriptors with predicted selection (lib/backends.py). |
| 2 | |
| 3 | Chained sources declare their routing once — imported from the definitions |
| 4 | lib/env.py already owns — and ``backends.resolve`` produces a truthful |
| 5 | "will use" prediction for alternative chains (X, YouTube, web search) plus |
| 6 | honest conditional wording for Reddit. |
| 7 | |
| 8 | Covers the plan's U2 scenarios: |
| 9 | 1. X with cookies present, bird healthy, no XAI key -> predicted ``bird``. |
| 10 | 2. Pin var set to a later backend -> pin honored and marked pinned. |
| 11 | 3. Preferred backend installed-but-unauthenticated does not shadow a |
| 12 | fully-usable fallback (collect-then-pick). |
| 13 | 4. No backend usable -> tier error; prescription from the highest-priority |
| 14 | backend. |
| 15 | 5. Paid lanes probe key presence ONLY — no network, no subprocess. |
| 16 | 6. Reddit renders conditional wording (default + backfill), never a |
| 17 | computed winner; a scrapecreators pin renders as pinned. |
| 18 | 7. Parity: descriptor prediction == pipeline's pre-failover X selection |
| 19 | (env.x_backend_chain()[0]) across three config permutations. |
