L1 Physics Engine Stability and Duplication Hardening

[dcplatforms]

This contribution delivers critical stability and security hardening to Layer-1 (L1) Physics Engine of the MiGrid operating system.

Core Achievements:

1. Resolved critical SyntaxErrors caused by duplicate functions/exports.
2. Formulated clean, type-safe telemetry utilities (safeFloat and safeFloatFormatted) that successfully enforce 4-decimal ML precision (Phase 6 Parity) and avoid fragile Jest test introspection.
3. Enhanced edge resilience with robust handlePhysicsAlert site-level extraction.
4. Consolidated Kafka/direct DER alarm handling with case preservation.
5. Deployed the July 2026 PO Weekly Report documenting cross-layer alignment.

Note

Medium Risk
Changes safety-lock Redis keying and telemetry type contracts on the L1 edge path; incorrect consumers could miss locks or mis-parse scores, though behavior is largely clarifying duplicates rather than new features.

Overview
Splits telemetry parsing so safeFloat returns numeric values for load/limit math while safeFloatFormatted owns four-decimal strings for confidence scores, physics metadata, and L11 audit parity; tests now target safeFloatFormatted for formatting cases.

Removes duplicate handleDerAlarm / export entries and replaces them with one handler that accepts either a plain alarm object or a Kafka-style { value } message, then writes both l1:safety:lock:SITE:<id> and l1:safety:lock:site:<id> on CRITICAL/HIGH DER alarms for cross-layer key compatibility.

Hardens handlePhysicsAlert site resolution by preferring top-level payload site fields before metadata, and adds the July 2026 weekly report documenting the cross-layer safety-lock alignment.
