"""Stress tests — real OSS repo transcripts (Medusa, Saleor, Vendure).

Status: FAILING until Phase 2 (SurrealDBLedgerAdapter) is complete.

These tests ingest the real meeting transcripts from pilot/ml/data/transcripts/
into the decision ledger and verify that the expected decisions can be retrieved.

Ground truth is defined in tests/fixtures/expected/decisions.py — edit that
file to tune what the system is expected to find.  That is the living artifact.
The test logic here stays stable; the expected decisions evolve.

Run: pytest tests/test_stress_oss_repos.py -v
