LoopGrid x Strands Agents v0.1.0 — release-candidate validation

Built against:
- LoopGrid Core contract: 0.8.1-design-partner
- LoopGrid Python SDK line: 0.8.x
- Strands Agents current line checked during build: 1.57.1

Completed in build environment:
- Current native Strands Plugin/@hook lifecycle cross-checked against official docs/source
- LoopGrid Core endpoint and lifecycle rules cross-checked against uploaded 0.8.1 source
- Python compileall: PASS
- Framework-independent plugin logic tests with Strands API stubs: 13/13 PASS
- Secret scan/manual package inspection: no credentials or .env secrets included

Must be completed on a machine with PyPI access before v0.1.0 is frozen/published:
- install actual strands-agents>=1.57.1,<2 and loopgrid>=0.8,<0.9
- run full pytest including native Strands Agent + Plugin + tool + deterministic custom Model test
- run local LoopGrid Core E2E demo
- confirm lifecycle=evidence_complete, coverage=100, verification.valid=true, failures=[]
- GitHub Actions green
- PyPI release
- Strands integrations catalog submission

This report is intentionally conservative. Runtime/E2E claims are not made until observed.

- Strands Plugin constructor regression: PASS (super().__init__ initializes native hook registry)
