GitHub REST API list issue comments default pagination per_page page Link header

💡 Result:

For the GitHub REST API endpoint to list issue comments, the default pagination settings are as follows: - per_page: The default number of results returned per page is 30, with a maximum limit of 100 [1][2][3]. - page: The default page number is 1 [1][2][3]. When an API response is paginated, GitHub includes a Link header in the HTTP response [4][5]. This header provides URLs that you can use to navigate between pages of results [5][6]. It contains links for the following relations [5][6]: - rel="prev": The URL for the previous page. - rel="next": The URL for the next page. - rel="last": The URL for the final page of results. - rel="first": The URL for the first page of results. If an endpoint does not support pagination, or if all results fit on a single page, the Link header is omitted from the response [5][7].

为 T6 的 issue comments 查询实现分页。

check_triple_survived 请求 /repos/{REPO}/issues/{issue_number}/comments 时未设置分页参数。GitHub 默认每页返回 30 条；api 也未保留 Link 响应头。当符合解析规则的 survived 评论位于后续页面时，T6 会找不到 run_id 并错误地 fail-closed。后续跨卡复用检查同样只读取第一页，也可能错误拒绝合法的 run_id。请读取全部分页结果，并增加跨页测试。

Remediation recommended

2. Comment pagination rejects evidence 🐞 Bug ☼ Reliability

Both fallback scans call the comments endpoint once without pagination, so GitHub returns only the
first 30 comments in ascending order and a valid survived record after comment 30 is invisible. On
such issues the label path is denied for missing run_id, while an old survived-looking record in
the first page may be selected instead of the current one.
Agent Prompt 
## Issue description
The new fallback reads only the default first page of issue comments, making valid evidence unreachable on issues with more than 30 comments.

## Issue Context
GitHub orders issue comments by ascending ID and defaults to 30 results on page 1. The local `api` helper performs a single request and does not follow pagination links.

## Fix Focus Areas
- .github/workflows/conductor.yml[122-134]
- .github/workflows/conductor.yml[398-428]

Fetch all comment pages (or query a bounded authoritative record directly), avoid duplicate comment requests, and select the evidence explicitly bound to the current lifecycle rather than the first historical match.

Action required

1. Untrusted comments bypass gate 🐞 Bug ⛨ Security

The fallback accepts any comment containing a survived substring and a run-like token, then the
existing check merely rediscovers that same token on the same issue; it never verifies the comment
author, the Actions run, or any binding to card_id, specVersion, or the current lifecycle. Thus
a stale or user-authored comment such as adversary:survived run_id=fake can satisfy T6 once an
owner applies the transition label, despite the transition contract forbidding historical/cross-card
evidence.
Agent Prompt 
## Issue description
The label-path fallback treats arbitrary issue-comment text as a valid adversary audit record, without proving that the run exists, succeeded, produced a survived verdict, or belongs to this card/spec/current lifecycle.

## Issue Context
T6 is documented as requiring a mechanically verified card ID + specVersion + audit run ID triple and rejecting historical/cross-card reuse. The fallback and subsequent check currently compare only an extracted token against the same comments that supplied it.

## Fix Focus Areas
- .github/workflows/conductor.yml[377-429]
- governance/transitions.yaml[69-92]

Require a structured record from a trusted producer, verify its author/provenance, and query the Actions API (or another authoritative audit store) to confirm the run, survived result, card, spec version, and current lifecycle binding before allowing T6.

Major：不要把任意 issue 评论当作权威审计记录。

此分支按评论正文的子串和首个正则匹配直接设置 run_id。它不验证评论作者、成功 check/run、当前 specVersion、当前生命周期或 ADR-0062 hash 链。旧评论、被编辑的评论或伪造的 verdict=survived run_id=... 都可能通过；后续检查使用相同规则，不能恢复真实性。T6 现在允许 owner 触发，因此该组合可绕过真实 adversary run。

请改为校验不可变且可追溯的审计记录，并将 card、specVersion、run_id 绑定到当前生命周期。不要以自由文本评论作为唯一证据。

As per coding guidelines：append-only 账本要求用量/生命周期/分诊/fan-out 产物只增不改，并使用 ADR-0062 hash 链。

In @.github/workflows/conductor.yml around lines 402 - 405, Replace the

branch with validation of an immutable, traceable ADR-0062 append-only audit

assigning it; ensure subsequent checks reuse this validated record rather than
free-text comments.
