Chronic-exploit flag (≥3 incidents)

Yearn Finance's assessment for RD-F-078 — scored red on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

4 confirmed distinct incidents in hack database (2021-02-04, 2023-04-13, 2023-11-30, 2023-12-16). Threshold for CHRONIC flag fires at ≥3. Binary flag = red. CHRONIC badge determination (PD-022 same-root-cause ≥3) is borderline — the identical Fulcrum-misconfiguration class has 2 events; broader 'legacy immutable/abandoned' meta-class has 3 events within 8 months — requires_curator_input for final badge call. F078 scores red on incident count alone (4 ≥ 3).
