Layer 3 of 9 in the source-control plugin boundary stack: forge knowledge (GitHub, GitCafe, GitLab, Forgejo, Bitbucket, Azure DevOps) moves into packages/source-control-<forge>, and shared, contracts, server and clients ask forge-neutral hooks in source-control-core instead.

builtInDrivers.ts deep-imported every forge's internals and assembled their layers with provideMerge, so forge-private services such as GitHubCredentials leaked into the whole server context, and the server's GitHub media fetch only worked because of that leak. Both registries also called each driver's make. GitHub media URL rules lived in shared, client-runtime and the server, and the repository service special-cased a Bitbucket error.

A driver's make now requires only what core names SourceControlDriverServices (SourceControlHost, SourceControlRateLimit, HttpClient, FileSystem, Crypto) plus a scope; each forge's server/driver.ts builds its own services with withOwnServices. builtInDrivers.ts builds every instance once, as the SourceControlDrivers service, and both registries and the asset route read it, so GitHub's quota reserve still exists once per process. The rate-limit pause is the server's, shared with the pull request service as before.

Client definitions gain a mediaUrl hook (GitHub implements it with the old shared rules plus the bare-upload video rule) and the registry asks all of them. Driver instances gain an optional fetchMedia, which GitHub implements with its credential; the server keeps the response policy (content types, SVG CSP, caching). The Bitbucket provider now puts its workspace/repository hint in the neutral error's detail, and the repository service passes any provider's detail through. measure-pr-preview moves into the GitHub package.

Compatibility: the asset resource keeps its "github-media" wire tag, exported from contracts as SOURCE_CONTROL_MEDIA_ASSET, because servers and clients of different releases must keep agreeing on it and the server works out the host from the URL. Signed asset claims are unchanged, so outstanding URLs survive an upgrade. AssetGitHubMediaUrlValidationError is renamed AssetSourceControlMediaUrlValidationError; clients do not branch on it.

Behaviour changes: repository lookup, clone and publish errors show the provider's own detail instead of a generic message. The PR body attachment link reads "Open attachment on ". A bare www.github.com upload link is treated as a video like a github.com one. A malformed Bitbucket environment setting is a defect at startup rather than a typed layer failure.

Correction to my inline note on apps/server/src/assets/sourceControlMediaResponse.ts:25: please disregard the request to turn the response helper into a service method. It acquires the registered Effect service and delegates media fetching to the driver; the cited placement convention does not require a separate service for this transport-response helper.

Walkthrough

The change adds source-control media recognition and driver-based fetching. It updates asset issuance, server responses, and mobile and web media rendering. It also changes built-in driver construction and registration, and adds provider-neutral repository error details.

Changes: Source-control media and drivers

Layer / File(s)	Summary
Media contracts and URL recognition `packages/source-control-core/src/client/definition.ts`, `packages/contracts/src/assets.ts`, `packages/source-control-github/src/client/*`	The client registry now recognizes media URLs and returns fetch details. The GitHub client implements URL recognition, and the asset contract exports a shared media tag and validation error.
Driver services and media fetching `packages/source-control-core/src/server/driver.ts`, `packages/source-control-/src/server/driver.ts`, `packages/source-control-github/src/server/`, `packages/source-control-github/scripts/measure-pr-preview.ts`, `packages/source-control-github/tsconfig.json`, `knip.jsonc`	The driver interface adds optional media fetching and fixed service requirements. Built-in drivers provide their own service layers. The GitHub driver adds credential-aware media fetching; its preview script and package configuration are updated.
Built-in driver registry `apps/server/src/sourceControl/builtInDrivers.ts`, `apps/server/src/sourceControl/builtInDrivers.testkit.ts`, `apps/server/src/sourceControl/Registry`, `apps/server/src/pullRequest/PullRequestProviderRegistry.ts`, `apps/server/src/server.ts`	The server collects built-in driver instances into a registry. Provider registries and repository identity refinement use that registry, and tests provide the built-in driver layer.
Asset issuance and media responses `apps/server/src/assets/AssetAccess.ts`, `apps/server/src/assets/AssetAccess.test.ts`, `apps/server/src/assets/sourceControlMediaResponse.ts`, `apps/server/src/assets/GitHubMediaFetch.ts`, `apps/server/src/http.ts`, `apps/server/src/ws.ts`	Asset issuance resolves media through the source-control client registry. The server selects a driver to fetch media and streams validated media responses. The GitHub-specific response module is removed.
Mobile and web media rendering `apps/mobile/src/features/pull-requests/*`, `apps/mobile/src/lib/videoPreviewSource.ts`, `apps/web/src/components/ChatMarkdown.tsx`, `apps/web/src/components/chat/ChatMarkdownMedia.tsx`, `apps/web/src/components/pullRequest/PullRequestMarkdown.tsx`, `packages/client-runtime/src/pullRequestMarkdown.ts`	Mobile and web consumers use the shared media tag and source-control URL registry. Pull-request rendering identifies host media and video, and chat markdown loads recognized source-control media.

Source-control repository errors

Layer / File(s)	Summary
Provider error details `apps/server/src/sourceControl/SourceControlRepositoryService.ts`, `apps/server/src/sourceControl/SourceControlRepositoryService.test.ts`, `packages/source-control-bitbucket/src/server/BitbucketSourceControlProvider.ts`, `packages/source-control-bitbucket/src/server/BitbucketApi.ts`, `packages/source-control-core/src/server/SourceControlProvider.ts`	Repository lookup maps provider error details to user-facing messages. Bitbucket operations use repository locator details when available.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This is a broad source-control architecture refactor that changes driver lifecycles, credentialed media fetching, asset serving, and web/mobile behavior across production paths. Its scope and unresolved service-boundary and data-handling concerns warrant human review.

No code changes detected at 89dde9c. Prior analysis still applies.

Review follow-up, now on the pushed heads:

prcomment_01m5nmerhxf4q8k3rmzcchga6n DISMISS: pre-existing shape: main's http.ts already called the free function githubMediaResponse (assets/GitHubMediaFetch.ts); this layer only moves the fetch into the GitHub driver. Turning asset media into a service is a separate refactor.
prcomment_01m5nmrbdped3ag1z37fdzj52b FIXED(L3): only a failure's userFacingDetail (Bitbucket locator hint) is shown; other detail gets the generic message; tests both ways
prcomment_01m5nmyzc2e1jr7q50bj1tmx45 FIXED(L3): log host only
prcomment_01m5nmyzh8ev8rqw18jd91kdy1 FIXED(L3): keep AssetGitHubMediaUrlValidationError wire tag
prcomment_01m5nmyzpseysrs59dxg0amvad FIXED(L3): same as the detail finding above

Review follow-up on d407a88:

prcomment_01m5pkfsvffbfv8wxf82fxpws7 FIXED: the media-fetch warning now logs only the host and the failure kind (cause.reason._tag). The raw error, and the signed request URL it holds, are no longer logged. (Main logged the full URL and the raw error, so this tightens existing behaviour.)
