fix(policy): classify agent base-policy presets distinctly in explain - #9082
Conversation
`policy explain` reported a Hermes base-policy preset (`pypi`, from agents/hermes/policy-additions.yaml) as `gateway-only (not in local registry)` — implying registry drift — solely because its name collides with the built-in catalog preset `pypi`. The sibling Hermes base additions (managed_inference, nvidia, nous_research) have no catalog entry and were never reported, so the classification depended on an incidental name collision rather than provenance. The implied remediation, `policy add pypi`, replaces the enforced GET-only base rule with the broader catalog preset, which additionally permits an agent-writable binary path (/sandbox/.venv/bin/python*) — a data-exfiltration channel introduced by a command whose stated purpose is to reconcile a status report. Classify a gateway-enforced-but-not-applied catalog preset supplied by the sandbox agent's base policy as `agent-base` instead of `gateway-only`. Such a preset is active (enforced), not drift; it stays in the active set and is never suggested for `policy add`. The access-failure classifier treats `agent-base` as enforced, matching `verified`.

At head dd87d025f6494d4bce5dda94ea7ff65ad0a8fb35, one behavior/documentation inconsistency remains blocking for a policy explanation change.
failure-classifier.ts treats gateway-only as gateway-confirmed enforcement, but the generated POLICY.md text says every status other than verified or agent-base is advisory and must not be assumed enforced. The public page also omits the new agent-base branch from its network-block classification: the implementation returns high-confidence unknown, like verified, rather than the low-confidence policy verdict described for other states. This can make an agent act differently from the classifier contract based on the explanation intended to guide it.
Please align the generated text and public documentation with the classifier, and add rendering/documentation coverage for the full status matrix. This confirms the existing inline CodeRabbit finding after checking it against the head.
The failing CLI shards appear to be unrelated base-branch expectation drift in maintainer/E2E tests, not failures in these changed policy files; I did not treat those as a PR defect.
Security review:
- Input validation — PASS: agent and preset identifiers flow through existing validated loaders.
- Authentication and authorization — PASS: no permission change.
- Secrets and sensitive data — PASS: policy output remains redacted.
- Injection — PASS: no new shell or query construction.
- Cryptography — PASS: no cryptographic changes.
- Dependencies and supply chain — PASS: no dependency changes.
- Error handling and information exposure — PASS: load failures retain the prior best-effort classification.
- System security and sandbox boundaries — WARNING: enforcement is unchanged, but inconsistent agent-facing guidance can misclassify policy failures.
- Testing — WARNING: status rendering/classification tests do not catch the inconsistent guidance.

Approved. Policy guidance now matches the classifier, direct Hermes catalog-collision coverage exercises the loader, all required checks pass, and all review threads are resolved.
