## Thinking Path > - Paperclip helps people manage AI agents for work. > - Maintainers use Storybook to review the board UI. > - Reviews need public previews of selected repository branches. > - Each branch needs its own URL so previews do not replace each other. > - This pull request adds manual, CODEOWNER-controlled publishing to S3 and CloudFront. > - The action returns stable branch links and permanent build links in its summary and a Markdown artifact. ## Linked Issues or Issue Description **What existing behavior does this improve?** The existing Storybook build and manual visual-review workflow. **Current behavior** The repository has no manual branch-preview publisher. A single GitHub Pages site cannot support independent publishers without combining their output. **Proposed behavior** A CODEOWNER selects a source branch and approves publication. Each branch has a stable CloudFront URL. A completed build becomes the branch target only after its upload succeeds. The action attaches `storybook-deployment.md` with the preview links and source commit. **Reason and benefit** Maintainers can share multiple branch previews at the same time. Branch builds have no repository token permissions or AWS credentials. Dependency caching and install hooks are disabled. The publisher cannot write runner dashboard files or delete objects. **Breaking changes** None. Normal visual checks keep their existing behavior. This does not change application code or GitHub Pages settings. **Additional context** Searched public issues and PRs for Storybook deployment work. No duplicate deployment proposal was found. This is maintainer infrastructure, not a roadmap-level core feature. ## What Changed - Add `Storybook Deploy` with a source-branch input and a manual entry through `Storybook Visual`. - Check the original actor and rerunner against default-branch CODEOWNERS. Require a protected deployment environment with CODEOWNER reviewers. - Separate public-source builds with no repository permissions from an OIDC publisher restricted to the Storybook S3 prefix. - Publish distinct branch URLs and retain build URLs. Preserve Storybook deep links across the branch redirect. - Add the run summary, a downloadable Markdown deployment report, focused tests, and operator setup docs and IAM policies. ## Verification - `node --test scripts/__tests__/storybook-deploy.test.mjs`: 19 tests pass. - `actionlint .github/workflows/storybook-deploy.yml .github/workflows/storybook-visual.yml`: passes. - [Feature branch live publication and deployment-only rerun](https://github.com/paperclipai/paperclip/actions/runs/34533202273): passed. - [Master branch live publication](https://github.com/paperclipai/paperclip/actions/runs/34533204743): passed. - Both public branch URLs render a component story without browser errors. A deployment-only rerun updates only the selected branch entry and preserves the previous build URL. - AWS policy simulation allows Storybook uploads and denies dashboard writes and object deletion. - Full local typechecking passes. Full local tests, build, and current-head PR checks are running. - [Revised build and Markdown artifact validation](https://github.com/paperclipai/paperclip/actions/runs/34605623088): passed. Downloaded the report and verified its branch URL, build URL, and source commit. - The public verifier also checks that the stable branch URL points to this build and rejects stale targets. ## Risks - Storybook previews are public. Maintainers must publish only public UI fixtures. - Retained builds accumulate until an operator prunes them. - Environment reviewers must stay synchronized with CODEOWNERS. The workflow fails closed if its environment loses required protection. - The existing CloudFront distribution is shared with runner reports. Separate S3 prefixes and a dedicated role prevent the publisher from overwriting those reports. ## Model Used OpenAI GPT-6 via Codex, with reasoning, shell tools, and browser verification. The exact runtime model ID and context-window size are not exposed in this session. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>

Storybook branch hosting
The Storybook Deploy workflow publishes public static Storybook builds to the
existing private S3 bucket behind CloudFront. It does not deploy to GitHub Pages.
Current destination
- AWS account:
078455283791, regionus-east-1 - Bucket:
paperclipai-runner-e2e-history-078455283791-us-east-1 - Allowed upload prefix:
storybook/branches/ - Distribution:
E3GTU28BBO2SFR - Public origin:
https://d1p6rlowie26tp.cloudfront.net - Role:
arn:aws:iam::078455283791:role/paperclip-storybook-github
The distribution's default behavior disables edge caching and rewrites directory
URLs to index.html. Stable branch indexes send no-cache; unique build objects
send immutable. No invalidations or CloudFront write permissions are needed.
GitHub configuration
Create environment storybook-deploy with required reviewers set to the
individual CODEOWNERS accounts. Disable administrator bypass, allow self-review,
and allow repository branches. Keep these reviewers synchronized with CODEOWNERS.
The workflow rejects environments with no required reviewers, non-owner reviewers
or administrator bypass enabled. The AWS role trusts only this repository and
this environment, so a branch cannot obtain upload access through an unprotected
environment.
Set repository variables:
| Variable | Value |
|---|---|
STORYBOOK_AWS_ROLE_ARN |
arn:aws:iam::078455283791:role/paperclip-storybook-github |
STORYBOOK_AWS_REGION |
us-east-1 |
STORYBOOK_S3_BUCKET |
paperclipai-runner-e2e-history-078455283791-us-east-1 |
STORYBOOK_PUBLIC_BASE_URL |
https://d1p6rlowie26tp.cloudfront.net |
No stored AWS access keys are needed. Leave the runner dashboard variables and GitHub Pages configuration unchanged.
Operator setup
Use the paperclip-dev operator AWS profile. Review the checked-in policies in
.github/storybook-deploy/ before applying them. The existing GitHub OIDC provider
must be present in this account.
aws sts get-caller-identity --profile paperclip-dev
aws iam create-role --profile paperclip-dev \
--role-name paperclip-storybook-github \
--assume-role-policy-document file://.github/storybook-deploy/trust-policy.json
aws iam put-role-policy --profile paperclip-dev \
--role-name paperclip-storybook-github --policy-name StorybookBranchUpload \
--policy-document file://.github/storybook-deploy/upload-policy.json
For an existing role, use update-assume-role-policy instead of create-role.
Add the statement from cloudfront-read-statement.json to the existing bucket
policy's Statement array. Preserve every other statement, including the HTTPS
requirement and runner report access. Keep all S3 public-access blocks enabled;
only CloudFront receives read access to this public-content prefix.
The role has no delete, bucket policy, IAM, CloudFront, or root-object permissions.
The workflow never runs sync --delete. Builds accumulate; any retention cleanup
must preserve the build referenced by each branch entry.
Verification
node --test scripts/__tests__/storybook-deploy.test.mjs
actionlint .github/workflows/storybook-deploy.yml .github/workflows/storybook-visual.yml
Dispatch two source branches, approve each deployment, and check their distinct
branch URLs and each build's deployment.json. Redeploy one branch and confirm
its stable URL now points to the new build while the other branch is unchanged.
The publisher checks the public build metadata against the selected source SHA
and verifies that the public branch entry points to this exact build. It retries
brief propagation delays and fails if the branch URL remains stale.
