Phase 1 security fixes from v2 audit (2026-03-10): pyth-adapter-v1: - Reject zero/negative prices before to-uint conversion (H-1, H-9, M-15) - Bound exponent to [-18, 18] to prevent pow overflow (M-3) - Cap future timestamps to 60s tolerance (M-2) - Enforce time-delta range [60s, 7200s] (M-1) - Remove dead zero-price branch in check-confidence - Add named constants MAXIMUM_TIME_DELTA, FUTURE_TIMESTAMP_TOLERANCE linear-kinked-ir-v1: - Guard utilization-calc division by zero on total-assets (H-2) - Guard elapsed-block-time underflow with saturation to u0 (H-10) linear-kinked-ir-utility: - Same division-by-zero and elapsed-time underflow guards (L-32) liquidator-v1: - Unconditionally reject zero repay amount (H-1 defense-in-depth) tests: - Add pyth-adapter oracle hardening tests (price, exponent, timestamp, time-delta) - Add utilization zero-total-assets test - Fix pyth test helpers to use simnet-aligned timestamps - Update all test files for time-delta max of 7200 - Add price refreshes for long-running test scenarios 207/207 tests pass.
