Issue ID: SONE033
Status: ✅ RESOLVED
Release Date: [Insert Date]
Affected Systems: [e.g., Core API v3, Data Pipeline, UI Module]
The TIMER0 register’s fixed‑point representation makes it particularly vulnerable to fractional overflow. Traditional overflow checks (e.g., saturating counters) are insufficient because a missing increment can shift the fractional part, causing the integer portion to under‑flow—exactly what happened in SONE033. The idempotent update strategy preserves the invariant that the fractional part never loses a tick, guaranteeing deterministic watchdog behavior. sone033 fixed
