feat(lowering): send deploy source and client headers to the Management API

[gregory-boch-prisma]

Linked issue

n/a — small change. Server side: prisma/pdp-control-plane#5284.

Summary

The Prisma Management API now records where each Compute deploy came from in its analytics, and which tool sent it. It cannot tell a GitHub Actions deploy from a laptop deploy today, because every deployment create and start call comes from alchemy's Prisma client with the User-Agent alchemy-prisma/1.0.

Composer now adds three headers to its Management API requests:

Header	Value
x-prisma-deploy-source	github-action when GITHUB_ACTIONS is "true", otherwise composer
x-prisma-client-name	composer
x-prisma-client-version	the package version

• alchemy's Prisma client: upstreamPrismaProviders now provides a node transport wrapped with HttpClient.mapRequest. makePrismaClient captures that client when its layer is built, so every deployment, app, database and bucket call carries the headers.
• The artifact upload is unaffected. It resolves HttpClient when it runs, from the ambient client that providers() exposes, so presigned upload URLs get no extra headers. The private-vs-ambient invariant in providers.ts still holds.
• Composer's own management client (client.ts) passes the same headers through createManagementApiClient's headers option.

The headers change analytics only; the API behaves the same without them. They carry no user data. Users pick this up when they upgrade Composer in their app, because alchemy deploy runs from the app's own node_modules.

Testing performed

• pnpm build, then in packages/1-prisma-cloud/0-lowering/lowering: tsc --noEmit (clean) and bun test (192 pass).
• pnpm lint (clean), pnpm lint:casts (delta 0).
• New src/__tests__/deploy-source-headers.test.ts: the source inside and outside GitHub Actions, the client name, and a semver-shaped version.
• Checked by reading alchemy@2.0.0-beta.74: makePrismaClient captures HttpClient at layer build (Client.ts), and executeArtifactUpload uses PrismaUploadClient if provided, otherwise the ambient HttpClient (Internal/ArtifactUpload.ts).

Checklist

• All commits are signed off (git commit -s) per the DCO. Pending: the commit author needs to add their sign-off (git commit --amend -s --no-edit && git push --force-with-lease).
• I read CONTRIBUTING.md and the change is scoped to one logical concern.
• The PR title is a conventional commit.
• Tests are updated.

Summary by CodeRabbit

• New Features

  • Deployment requests now include client, package version, and deployment-source information.
  • GitHub Actions and Composer environments are identified in deployment metadata.

• Tests

  • Added coverage for deployment-source detection, package-version formatting, fallback behavior, and environment restoration.

Walkthrough

The change adds deploySourceHeaders, which reports the package version, Composer client name, and deployment source. It selects github-action when GITHUB_ACTIONS is "true" and otherwise selects composer. A scoped Prisma management HTTP layer adds these headers to requests. The management client and Prisma provider now use this configuration. Tests cover environment handling and header values.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to de0dc

The deployment-header test coverage now verifies the package version exactly, and no unresolved issue remains for this change.

Change walkthrough

This PR makes Composer's Management API traffic attributable in deploy analytics: three static headers (x-prisma-deploy-source, x-prisma-client-name, x-prisma-client-version) are added to both the alchemy provider transport and Composer's own management client, derived from GITHUB_ACTIONS and the package version in a new deploySourceHeaders() helper.

Header source (credentials.ts) — A single pure-ish function produces all three headers, so Composer's SDK client and the upstream alchemy transport can never disagree about who is calling. Values are a fixed set plus pkg.version; no user data flows into them, so there is no injection surface.

Composer's own client (client.ts) — Headers go through the SDK's headers option inside the same layer effect that already resolves token and base URL, so they are captured once at client construction alongside everything else the layer reads.

Upstream alchemy transport (providers.ts) — The node transport is wrapped with HttpClient.mapRequest in a new private layer that replaces the previous bare NodeHttpClient.layerNodeHttp dependency. Because it is wired with Layer.provide (not provideMerge), the layer's output service set is unchanged and the bundle's ambient HttpClient still comes from the top-level plain node transport — preserving the documented invariant that the artifact-upload path (which resolves the ambient client for Content-Length reasons) receives no extra headers.

Tests (deploy-source-headers.test.ts) — Cover the three source branches (true, unset, other values) plus both fixed headers, with correct save/restore of GITHUB_ACTIONS.

Findings outside the diff

• 🟡 Minor · consistency packages/1-prisma-cloud/0-lowering/lowering/src/builds/reporter.ts — Third createManagementApiClient call site (builds/reporter.ts) sends no deploy-source headers
  The PR wires deploySourceHeaders() into two of the three createManagementApiClient call sites — client.ts:34 and the wrapped transport in providers.ts:51 — but not the standalone build-reporter client in src/builds/reporter.ts (built at line 133 for the CLI process, driving buildsApi and applicationTopologyApi). Every deploy also reports its build session and topology through that client, so if the Management API attributes Composer-originated traffic by the new client headers, that traffic stays unattributed while deployment/app/database/bucket calls from the same alchemy deploy run now say composer. If the omission is deliberate because build-report analytics key off resolveRunIdentity instead, a comment at the call site saying so would prevent the next reader from re-deriving it.
  Recommended fix: Pass the same headers at the standalone call site — createManagementApiClient({ token: token ?? '', baseUrl: ..., headers: deploySourceHeaders() }) — or document why build-session reporting is exempt.
