## Description

Route retrieval of Chinese medical guidelines, consensus statements, regulatory documents, drug information, safety notices, standards, and public-health materials through authoritative originals and verified fallback copies. Use when a canonical medical source is blocked, slow, unavailable, moved, paywalled, or difficult to parse, or when designing and auditing domestic medical-source fallback rules. Do not treat secondary summaries or reposts as independent clinical evidence.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Medical Source Failover

Retrieve the intended medical document reliably without laundering a secondary source into primary evidence.

## Non-negotiable invariant

**Degrade the access path, never the document identity or evidentiary standard.**

- Keep authority, document quality, access health, and retrieval priority as separate judgments.
- A domain's reputation does not grade every item published on it.
- A repost that reproduces the same document is an access carrier, not independent corroboration.
- A summary, interpretation, search snippet, news item, or social post may help discover an original; it must not support a precise recommendation, dose, contraindication, or evidence grade.

## Load the relevant references

- For any domestic medical retrieval, read [references/domestic-source-registry.md](references/domestic-source-registry.md) before selecting sources. It defines authoritative scope, discovery-only sources, fallback relationships, and how to extend the registry.
- When a page is blocked, slow, moved, paywalled, incomplete, or unparseable, read [references/failover-policy.md](references/failover-policy.md) before retrying or switching hosts.
- Before using a repost, mirror, alternate PDF, cached copy, or database full text, read [references/document-identity.md](references/document-identity.md) and verify that it is the same document and version.
