## Open now

- PR #23260: fix(kimi): strip trailing v1 for anthropic endpoints

Members describe a shared problem where an Anthropic-style base_url ending in /v1 (including the kimi-coding provider's /coding/v1) can lead to a doubled /v1/v1/messages URL and HTTP 404 errors. Several pull requests propose stripping or normalizing the trailing /v1; this label does not assert whether any were merged or fixed the issue.

## TL;DR

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.19`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
