| 1 | """TDD spec for EntangleProvider — issue #13, Phase 5. |
| 2 | |
| 3 | Verifies that EntangleProvider reproduces the same co-change analysis as |
| 4 | ``muse code entangle``: Jaccard-min rate, import filter, mass-commit exclusion, |
| 5 | canonical pair ordering, and repo isolation. |
| 6 | |
| 7 | Eight test tiers (54 cases) |
| 8 | --------------------------- |
| 9 | Unit ET_01 – ET_08 rate formula, import filter, pair canonicalisation |
| 10 | Integration ET_09 – ET_18 provider upserts, re-runs, row counts |
| 11 | E2E ET_19 – ET_25 full seeded scenarios |
| 12 | Stress ET_26 – ET_30 500-symbol batch, mass-commit exclusion |
| 13 | State ET_31 – ET_36 idempotency, incremental updates, stale-row purge |
| 14 | Integrity ET_37 – ET_41 corrupt addresses, NULL exclusion, file-same filter |
| 15 | Performance ET_42 – ET_46 timing bounds on realistic datasets |
| 16 | Security ET_47 – ET_54 injection strings, repo isolation, address length cap |
