对 RAG 段落分类
对 RAG 段落分类
用一次 TypeSafe 请求给每个检索到的段落打分，再在代码里决定哪些能到达作答的模型。
RAG 流水线的检索步骤按段落措辞与查询的相似程度排序，并把最靠前的几个交给语言模型。这些段落里可能混有噪声或无关内容，更糟的是，可能把相互矛盾的事实、提示词注入或针对模型的指令，和名义上的证据混在一起，一起送去协助生成答案。
在检索和生成之间，加一个第二阶段，对每个检索到的段落分类。对每一个，给 TypeSafe 发一个请求，携带关于查询-段落对的多个问题：它相关吗、它陈述了答案里可用的东西吗、它与查询视为理所当然的东西相矛盾吗、它在试图给模型下指令吗。这些问题的答案通过简单的分支逻辑决定每个段落的去向：作为证据加进提示词，作为冲突信息加进提示词，或丢弃。证据与冲突放在不同的块里到达，这样生成器可以做出恰当的应对。
为了演练这条流水线，我们用它跑一些刁钻的问题，对手是真实的 auth 文档——里面满是读起来雷同的页面，还故意埋了一个带提示词注入的段落。其中两个问题含有错误的前提，它们会在交给生成答案的模型之前被标记出来。
按各节构建的顺序，这条流水线是：81 个段落的语料库、为每条查询保留前 12 个段落的余弦相似度搜索、为其中每个段落发给 TypeSafe 的四个 Noul 问题、route() 中给每个段落打标签的阈值、由独立的证据块和冲突块拼装成的提示词，以及 claude-sonnet-5 据此写出的答案。

每个段落带 id、title、text 和 source_type，每个请求都会发送这四项。近似干扰项构成了整个集合。轮换、过期、会话和签名密钥各占自己的页面，而这些页面读起来很像。刷新令牌轮换和 JWT 签名密钥轮换是不同的东西，却用几乎相同的话来描述。

对每个段落提四个问题
把查询和一个段落一起放进 state，这样每个问题针对的都是这一对，而不是孤立的段落。形状：
{
"query": "Refresh tokens expire after 30 days - how do I extend that window?",
"passage": {
"id": "sessions-01",
"title": "User sessions: What is a session?",
"text": "A session is created when a user signs in...",
"source_type": "official_documentation"
}
}每条查询都用同样这四个问题。调用之间只有 state 会变。
四个 Noul 问题，以及每个答案驱动什么：
is_relevant：相关性的底线。contains_answer_evidence：纳入，还是丢弃。contradicts_query_premise：升级到冲突块。contains_prompt_injection：直接排除。
这四个问题没有一个在问要不要纳入这个段落。那个决定放在下面的代码里，改它就意味着改一个数字，而不是重写问题。
PASSAGE_QUESTIONS = {
"is_relevant": Noul(
instructions="Does this passage address the subject of the query?",
),
"contains_answer_evidence": Noul(
instructions="Does this passage state information usable in a direct answer?",
),
"contradicts_query_premise": Noul(

with ThreadPoolExecutor(max_workers=4) as pool:
return list(pool.map(lambda passage: gate(query, passage["id"]), passages))在代码里给每个段落路由
每个答案都以概率返回，把四个概率变成一个决定有很多种做法。这里用一串朴素的比较就够了。按固定顺序拿四个概率和它们的阈值比较，第一个命中的就停。这次命中给段落打上标签，标签决定它的去向：作为证据进提示词、作为冲突进提示词，或丢弃。
测试顺序如下：
contains_prompt_injection > 0.70-> excludecontradicts_query_premise > 0.70-> conflicting_evidenceis_relevant < 0.45-> excludecontains_answer_evidence > 0.55-> include- otherwise exclude
注入排在最前，因为它是安全决定，而不是证据决定。矛盾测试排在证据测试之前，因为一个否认查询前提的段落通常也陈述了可用的东西；要是把顺序反过来，它就会落进已接受的块，而不是冲突块。

注入问题是一个过滤器，而且只是一个。分数低于阈值的段落仍然会到达提示词，所以生成器的提示词必须把所有段落都当作不可信文本，无论它的分数如何。这里没有任何东西构成安全边界。
每个段落一个请求，所以成本随 k 增长。没有把多个段落批进一个请求，因为每个问题针对的是一对。
用已接受的证据拼装提示词
TypeSafe 给段落打分，路由给它们贴标签。答案仍然由 LLM 来写，这里是 claude-sonnet-5。把已接受的证据和冲突证据放在不同的块里。
两个块让答案可以反驳。把它们合而为一，生成器就没办法分辨一个回答查询的段落和一个否认其前提的段落。

"Refresh tokens expire after 30 days - how do I extend that window?"
conflicting_evidence 1, exclude 11
I don't have sufficient accepted evidence to tell you how to extend a 30-day refresh token expiration window. No accepted passages were provided on this topic.
I also need to flag a conflict with the premise of your question: the only evidence available, [sessions-01], states that refresh tokens **never expire** — instead, they are single-use ("can only be used once") and are exchanged for a new access/refresh token pair each time the session is refreshed. It does not mention any 30-day expiration for refresh tokens. According to [sessions-01], a session instead ends due to sign-out, a security-sensitive action (e.g., password change), inactivity timeout, reaching a maximum session lifetime, or signing in on another device — not due to a fixed refresh-token expiry.
Since this passage is marked as conflicting/unverified evidence rather than accepted evidence, and no other sourced information addresses a 30-day refresh token limit or how to configure/extend one, I can't provide a reliable answer to your specific question. You would need documentation or configuration references that explicitly address refresh token or session lifetime settings to proceed safely.
========================================================================================
"How long should an access token live?"
include 4, exclude 8
**Recommended access token (JWT) lifetime**
- The **default and generally recommended expiration is 1 hour** [sessions-05].
- More broadly, access tokens are designed to be short-lived, **typically ranging between 5 minutes and 1 hour** [sessions-01].
- Setting expiration **above 1 hour is generally discouraged** for security reasons, though it "may make sense in certain situations" [sessions-05].
- Setting expiration **below 5 minutes (and especially below 2 minutes) is discouraged** in most cases, because [sessions-05]:
- It increases refresh token usage and load on the Auth server.
- Clock skew between servers and user devices can cause hard-to-debug errors.
- Supabase's client libraries try to refresh sessions ahead of expiry, which isn't possible if the window is too short.
- Access tokens should stay valid at least as long as your longest-running request, to avoid tokens expiring mid-request.
**Practical implication for key/secret rotation:** If your access token expiry is set to 1 hour, you should wait at least 1 hour and 15 minutes before revoking a legacy JWT secret, to avoid forcibly signing out active users (unless there's an active security incident requiring immediate revocation) [signing-keys-51-c].
**Related note on sign-out enforcement:** Access tokens remain valid until they expire even after a user signs out (sessions are removed from the database, but the JWT itself isn't invalidated early) unless you add extra validation logic against `auth.sessions`. The guidance here is to "adjust the JWT expiry time to an acceptable value" rather than rely on strict revocation checks for most use cases [sessions-09].
**No conflicts** were found between the passages — they consistently point to a default/recommended value of 1 hour, with an acceptable range of roughly 5 minutes to 1 hour, and caution against going much shorter or longer without specific need.第一个答案到达时，已接受的块是空的，只有一个冲突段落。它以“I don’t have sufficient accepted evidence”开头，点出了冲突，并引用 sessions-01 说明刷新令牌永不过期，而不是凭空编一个 30 天的设置。
第二个有 4 个已接受的段落、没有冲突，并引用了全部四个。注入指令没有任何一部分进入文本。

每根条带装着为一条查询检索到的 12 个段落，总共 72 个。每根条带至少三分之二都是被排除的。只有那两条错误前提的查询把东西路由到了冲突，还有两条查询什么都不接受：那条关于 30 天过期的，以及 how are refresh tokens rotated?
在 Playground 里打开
打开下面的链接可以实时重跑一次调用：用第一条查询对照那个被路由到冲突块的段落，再加上那四个问题。
linked = next(r for r in ROUTED[HEADLINE_QUERY] if r["route"] == "conflicting_evidence")
deeplink = make_playground_link(
gate_document(HEADLINE_QUERY, linked["passage"]),
