Research direction

Read SECURITY.md and inspect src/meridian/runtime/isolation.py, src/meridian/runtime/pytest_runner.py, and src/meridian/runtime/secrets.py to map each named trust boundary to its protections. Find the tests that exercise those protections and cite their paths alongside the enforcing code. Done when docs/threat-model.md covers each boundary, attacker-controlled inputs, and the relevant code and tests.

Written by the indexing model from the issue text.

Description

area: docs area: security documentation size: M
Context

SECURITY.md lists what is in scope, but there is no single description of the trust boundaries (agent, task files, cassettes, the proxy's credential, the grading sandbox) and what defends each.

What to do

Write docs/threat-model.md with each boundary, what an attacker controls, and the code that enforces it.

Done when

The document exists and each defence points at its file and test.

Where to look

src/meridian/runtime/isolation.py, src/meridian/runtime/pytest_runner.py, src/meridian/runtime/secrets.py
