## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The release pipeline keeps a canonical stable note at
`releases/vX.md` on master for every published stable.
> - Stable `2026.831.1` was a hotfix cut from a branch off
`v2026.831.0`, with its notes committed into the source tree.
> - In that path the workflow resolves notes in `source_tree` mode and
skips `canonicalize_stable_notes`, which is the job that normally copies
the note to master.
> - As a result `releases/v2026.831.1.md` exists on the tag but never
landed on master, so the stable-notes history has a gap.
> - This pull request adds the canonical copy of that note to master.
> - The benefit is a complete, consistent stable-notes history for
readers and for the release tooling.
## Linked Issues or Issue Description
No separate issue. Describing the gap in-PR with the docs template
fields:
**Issue type**
Documentation gap in the release-notes history on master.
**Where is the issue?**
`releases/` on the master branch — the file `releases/v2026.831.1.md` is
missing, although the stable `2026.831.1` release has already published.
**What's wrong?**
The `2026.831.1` patch was published from a hotfix branch whose notes
lived in the source tree (`source_tree` notes mode). That mode skips
`canonicalize_stable_notes`, the job that copies a stable's note onto
master. So every other stable has a `releases/vX.md` on master, but
`2026.831.1` does not.
**Suggested fix**
Add the canonical `releases/v2026.831.1.md` to master, identical to the
copy published with the tag.
## What Changed
- Add `releases/v2026.831.1.md` to master, copied verbatim from the
published `v2026.831.1` tag.
## Verification
- `diff` of the added file against `git show
v2026.831.1:releases/v2026.831.1.md` is empty (identical to the shipped
note).
- Docs-only change: no code, tests, or build outputs are affected.
## Risks
- Low risk. The change adds one Markdown file and touches no code,
schema, or configuration.
## Model Used
- Claude (Anthropic), model id `claude-fable-5` (Claude Fable 5), used
with tool use, shell commands, and file editing.
