Problem

Images that a private Bitbucket Cloud PR description links from the repository's Downloads (https://bitbucket.org/{ws}/{repo}/downloads/{file}) show "Image unavailable" in the PR panel. The client has no Bitbucket session, so Bitbucket answers 401. That web URL also ignores an API token. Only GitHub-hosted media went through the server's credentialed path.

Reproduce: upload a PNG to a private repo's Downloads, embed it in a PR description, and open the PR in the PR panel.

Change

• Contract: adds a bitbucket-media asset resource next to github-media, plus AssetBitbucketMediaUrlValidationError.
• URL mapping: @t3tools/shared/bitbucketMedia maps the web download URL to the API download endpoint (api.bitbucket.org/2.0/repositories/{ws}/{repo}/downloads/{file}). That is the endpoint that honours the token. Any other URL keeps loading directly.
• Server fetch: the server signs the resource, fetches it with the configured Bitbucket credential (Settings or T3CODE_BITBUCKET_*), and follows the 302 to the signed S3 object. The token is never sent to S3. It then streams the bytes back with the same media-type, SVG CSP and cache rules GitHub media already gets.
• Bitbucket package: the only new export is BitbucketApi.authorize. It adds the credential only to requests bound for the configured API origin, so the token never leaves the package as a value.
• Shared fetch module: GitHubMediaFetch.ts is renamed to PullRequestMediaFetch.ts. GitHub and Bitbucket now share one redirect loop and response shaper; each host supplies only its authorize step.
• Clients: web (ChatMarkdown, PullRequestMarkdown) and mobile (PullRequestMedia, pullRequestMediaSource, video thumbnail keys) pick the resource through one pullRequestMediaResource helper. ChatMarkdown's githubMedia prop is renamed to pullRequestMedia, and the URL is now parsed only when that flag is on.

Compatibility: a new client talking to an older server can't get the image signed, so it falls back to loading the image directly. That is today's behavior: public images load, private ones still fail.

Not covered:

• If T3CODE_BITBUCKET_API_BASE_URL points somewhere other than api.bitbucket.org, these downloads go out without the credential.
• GitLab uploads ([Bug]: Private GitLab uploads do not load in MR descriptions pingdotgg/t3code#11412) could be added the same way later.

Scope and approval

Fixes pingdotgg#19828. This follows the design proposed there: the credentialed server path that GitHub media already uses, applied to Bitbucket and limited to Bitbucket download URLs.

Verification

• apps/server/src/assets/AssetAccess.test.ts, new tests for:
  • the web URL and the API URL both signing and resolving to the API download URL;
  • http:, non-download paths, S3 links and GitHub links being rejected, without echoing the URL in the error;
  • a fetch where the API request carries the credential, the S3 hop carries none, and an application/octet-stream upstream is served as image/png based on the file name.
• apps/server/src/sourceControl/BitbucketApi.test.ts: the real authorize, built from the real layer, adds credentials for the configured API origin and leaves an S3 URL untouched.
• apps/mobile/src/features/pull-requests/pullRequestMediaSource.test.ts: a Bitbucket download resolves to a bitbucket-media resource.
• Results: server suites 82/82 pass, mobile 4/4 pass. tsc-rs --noEmit shows 0 errors in contracts, shared, source-control-bitbucket, server, web and mobile. Lint shows no errors on the changed files.

Not checked:

• I did not run this against a real private Bitbucket repository. The 401 and 302 behavior comes from the issue report, so there are no before/after screenshots.
• I did not do a pass in a real client.

Walkthrough

Pull-request media handling now recognizes Bitbucket Cloud downloads alongside GitHub media. The server can issue signed Bitbucket media assets and fetch them with Bitbucket API credentials. Mobile and web pull-request views use shared resources for hosted images and videos.

Changes: Pull-request media

Layer / File(s)	Summary
Media resource recognition packages/contracts/src/assets.ts, packages/shared/src/bitbucketMedia.ts, packages/shared/src/pullRequestMedia.ts, packages/shared/src/githubMedia.ts, packages/shared/package.json	Contracts and shared helpers add Bitbucket media resources, convert supported Bitbucket download links to API URLs, and provide shared filename handling.
Asset issuance and authorization apps/server/src/assets/AssetAccess.ts, packages/source-control-bitbucket/src/server/BitbucketApi.ts, apps/server/src/ws.ts, apps/server/src/assets/AssetAccess.test.ts	AssetAccess issues and resolves Bitbucket media claims after validating download URLs. BitbucketApi.authorize adds credentials only for the configured API origin. Tests cover URL validation and asset issuance.
Authenticated media delivery apps/server/src/assets/PullRequestMediaFetch.ts, apps/server/src/http.ts, apps/server/src/assets/AssetAccess.test.ts, apps/server/src/sourceControl/BitbucketApi.test.ts	The server dispatches GitHub and Bitbucket assets through shared response handling. Redirect requests use host-specific authorization. Tests check authorization, redirects, and inferred content type.
Pull-request rendering apps/mobile/src/features/pull-requests/*, apps/mobile/src/lib/videoPreviewSource.ts, apps/web/src/components/ChatMarkdown.tsx, apps/web/src/components/pullRequest/PullRequestMarkdown.tsx	Mobile and web views use shared media resources for hosted images and videos. Bitbucket media is included in video preview source handling.

Merge Risk: Low · up to 183c2

Private Bitbucket images and videos in pull request descriptions now load through the server. If a download fails, the server log may record details of the signed download link. Change the logging to record only bounded failure details; otherwise the change looks ready to merge.
