Summary

Standard framework builds produced by create-prisma currently fail in Composer's Compute packaging/runtime path:

  • Next.js standalone output contains safe framework and package-manager links that the current flat-bundle check rejects. pnpm output can also refer to traced targets that Next leaves outside .next/standalone.
  • SvelteKit's Node adapter crashes under Compute's current Bun URL custom-inspection semantics.
  • Astro's Node adapter leaves runtime packages external and defaults to loopback, while Composer currently deploys only dist.
  • pnpm peer-context links can exceed USTAR's fixed link-name field.

This PR is a temporary compatibility bridge for the current Compute provider. It does not rebuild or rewrite application output: Composer stages runtime files from the explicitly declared entry, preserves validated in-bundle topology, and adds narrowly scoped hosting compatibility.

Framework and packaging fixes

  • Next.js: preserve safe in-bundle links; for a missing pnpm target referenced by standalone output, stage only the corresponding traced path from Next's outputFileTracingRoot. The source and final target must remain inside that root. Dangling or escaping links still fail.
  • SvelteKit: install a Bun-only URL/URLSearchParams custom-inspect setter before importing the app. This restores the Node behavior expected by SvelteKit without changing generated application output.
  • Astro: trace the explicit Node adapter entry with @vercel/nft, stage its external runtime files beside dist, and default HOST to 0.0.0.0 without overriding an author value.
  • Archives: emit deterministic USTAR archives with POSIX PAX path/linkpath records when framework or pnpm paths exceed USTAR fields. Preserve only links whose resolved target is inside the assembled bundle; local extraction enforces the same boundary.
  • Bootstrap security: keep all caller-controlled bootstrap inputs in compute.bootstrap.json; bootstrap.js is constant code. This fixes the CodeQL code-construction finding and is covered by adversarial and execution tests.

Composer still uses the existing Management API contract: wait until the deployment reports running, then promote it. It does not poll the public URL or inspect internal routing headers.

Temporary ownership and the upstream Alchemy migration

The intended end state is the full Alchemy Prisma.Compute provider. Delete each local bridge only when the upstream provider demonstrably owns the same guarantee:

  • replace Composer's archive/link implementation when upstream createComputeArchive handles validated symlinks and long PAX paths;
  • remove Next.js pnpm target staging when the upstream Next strategy packages the complete traced standalone runtime;
  • remove Astro NFT staging when the upstream Astro strategy traces external runtime dependencies (the inspected beta.72 strategy copies dist only);
  • remove Composer's listen-all default when the provider/runtime reliably supplies the external bind address;
  • remove the SvelteKit shim when the provider/runtime supplies equivalent compatibility or Compute's Bun behavior is fixed.

Moving only the low-level resources to Alchemy is not enough to fix these framework failures. The deletion point is the later composite provider migration with equivalent behavior.

Testing performed

  • Exact create-prisma PR chore(drive): close out prisma-next-data-contract #53 preview: create-prisma@0.4.2-pr.53.191.1.

Checklist

  • All commits are signed off (git commit -s) per the DCO.
  • I read CONTRIBUTING.md and the change is scoped to one logical concern.
  • The PR title is a conventional commit.
  • Tests are updated.

Notes for the reviewer

Please review this as temporary hosting compatibility with explicit deletion conditions, not a permanent framework abstraction. ADR-0047 records the narrow boundary: users build; Composer assembles the declared runtime topology needed to execute that build.

Summary by CodeRabbit

  • New Features

    • Application bundles now preserve safe in-bundle symlinks and include traced runtime dependencies.
    • Compute artifacts support symlinks, long paths, executable permissions, and runtime bootstrap metadata.
    • Services default HOST to 0.0.0.0 when no host is specified.
  • Bug Fixes

    • Deployments now reject dangling or out-of-bundle symlinks with clear validation errors.
    • Improved compatibility for pnpm and Next.js standalone builds.
    • Deployment readiness now requires a promoted URL to return an application-owned response.
  • Documentation

    • Updated build guidance and architecture decisions to describe bundle assembly and symlink behavior.

Walkthrough

Framework assembly now traces runtime dependencies and preserves symlinks whose targets remain inside the bundle. Compute artifact generation and extraction preserve safe symlinks, executable modes, and long TAR paths through PAX metadata. Bootstrap values move to compute.bootstrap.json, with a Bun compatibility shim. Compute services default HOST to 0.0.0.0 when unset. Documentation and architecture records define the updated assembly rules.

Merge Risk: 🟠 High · up to d6db6

The PR changes how framework runtimes are assembled and promoted, but unresolved issues can allow files to be staged outside the intended bundle, cause successful deployments to fail during promotion when given a bare host, and break runtime-agnostic consumers. These should be fixed or explicitly accepted before merging.

Inline comments:
In `@docs/design/90-decisions/README.md`:
- Line 71: Update the ADR-0005 index entry to annotate that it is superseded in
part by ADR-0047, while preserving the existing “no laundering (symlink = hard
error)” text and following the annotation convention used by ADR-0009, ADR-0010,
ADR-0021, and ADR-0034.

In `@packages/0-framework/2-authoring/nextjs/src/control/build.ts`:
- Around line 137-141: Update stageMissingStandaloneLinkTargets to check whether
tracingRoot exists before calling fs.promises.realpath; when it is absent,
return an empty string array so assemble continues without staging sources,
while preserving the existing link-inspection behavior for present roots.

In `@packages/0-framework/2-authoring/node/src/control/build.ts`:
- Around line 222-231: Update the traced-dependency destination mapping in the
build loop and the corresponding symlink target mapping in copyTracedEntry so
dependencies are re-rooted under bundle according to Node lookup paths from the
entry, rather than preserving traceBase-relative workspace prefixes; retain
containment checks and existing copy behavior, and add a regression test
covering a workspace-depth layout where the entry can resolve the staged
dependency.

In `@packages/1-prisma-cloud/0-lowering/lowering/src/__tests__/artifact.test.ts`:
- Around line 319-357: Add a test alongside the existing symlink tests that
creates an absolute symlink target inside the bundle, packages it through
packageComputeArtifact, and verifies the archived node_modules/link target is
the bundle-relative name “real” rather than an absolute deploy-machine path. Use
the existing makeBundle, readTar, and archive.link helpers, and assert the link
does not contain the temporary bundle path.

In
`@packages/1-prisma-cloud/0-lowering/lowering/src/__tests__/Deployment.test.ts`:
- Line 44: Bound the retry schedule used by the probe in the Deployment test by
composing Schedule.spaced with a finite retry limit. Preserve the existing
1-millisecond spacing while ensuring persistent failures terminate after a
small, explicit maximum number of attempts.

In `@packages/1-prisma-cloud/0-lowering/lowering/src/compute/artifact.ts`:
- Line 103: Replace both localeCompare-based archive-entry sorts in the artifact
lowering logic with a locale-independent byte-order comparison, preserving
ascending relPath ordering and deterministic output for identical entry sets.
- Around line 273-285: Wrap the Bun compatibility shim in artifact
initialization around the Object.defineProperty calls for URL and
URLSearchParams so any installation failure is caught and does not interrupt
application startup. Preserve the existing inspect getter/setter behavior when
the properties are configurable.
- Around line 90-95: Update the symlink linkname construction in the artifact
lowering logic to normalize path separators for both absolute and relative
targets. Ensure the relative target branch converts platform-specific separators
to POSIX “/” before pushing the symlink entry, while preserving the existing
absolute-target behavior.
- Around line 219-226: Update the regular-file archive branch around ustarHeader
so its mode preserves the source entry’s owner-execute bit instead of always
using 0o644. Keep the existing readable/writable permissions and typeflag, and
apply the preserved executable mode to standalone and traced dependency files.

In `@packages/1-prisma-cloud/0-lowering/lowering/src/compute/Deployment.ts`:
- Around line 181-183: Normalize the URL used by the deployed endpoint probe in
the Deployment flow before calling probeDeployedUrl, ensuring schemeless
appEndpointDomain values become absolute HTTPS URLs while preserving
already-schemed URLs. Add a test covering the schemeless domain shape and verify
probing receives the normalized URL.

In `@packages/1-prisma-cloud/1-extensions/target/src/compute.ts`:
- Around line 108-111: Update the HOST initialization in compute.ts to treat
both nullish and empty-string values as unset, assigning the listen-all address
when HOST is absent or empty while preserving any non-empty explicit author
value.

Apply the review findings on PR #235:

- Derive the node adapter's staging root from the declared paths and
  the traced files themselves, not the invocation cwd: pnpm workspaces
  with a root-level virtual store assemble from any directory, layout
  is identical across invocation directories, and a root that
  degenerates to the filesystem root is a loud error naming the traced
  path that widened it.
- Detect staging collisions: two traced packages collapsing onto one
  bundle path is an error naming both sources instead of silently
  shipping whichever sorted first; dangling staged links no longer
  surface as raw EEXIST.
- Require lexical containment of the exact linkname the archive stores,
  in addition to the realpath check, so the writer and the extractor
  enforce the same boundary and a link that re-enters the bundle
  through an outside alias fails at package time.
- Validate the assembled Next.js bundle's links at assemble time (the
  node adapter already did), and error on a required link repair when
  the manifest records no outputFileTracingRoot instead of silently
  falling back and failing later in the packager.
- Extract the containment predicate and bundle-link walk into
  @internal/bundle-paths, replacing the five per-package copies; core
  stays runtime-neutral per its shipped-surface invariant.
- Align the binding docs with ADR-0047: architectural principles,
  AGENTS.md, ADR-0005's body, and the building-an-app guide no longer
  state the superseded flat-bundle rule; ADR-0047 now documents the
  PAX path dependency and the local scope of the HOST default.

- Move @internal/bundle-paths to the authoring floor: the runtime-
  agnostic principle covers core, and the predicate's consumers are
  control-plane build and packaging code.
- Give the package its own tests; a test script with no tests failed
  CI's bun run.
- Refuse a required-server-files.json whose recorded app location
  escapes its tracing root, instead of joining ..-segments into the
  bundle path.
- Reject an absolute symlink target at extraction: it could resolve
  inside the temporary directory and dangle after the rename into
  place.
- Document in the guide that the dir form traces the declared entry
  and stages its runtime imports beside the build output.

93-99: 🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Validate relativeAppDir against standaloneRoot.

Line 94 checks path.join(appDir, rel), but rel is later joined with bundleDir. Because appDir and standaloneRoot are different roots, a manifest can use .. segments that stay inside appDir while escaping the copied standalone tree. appOut can then point outside bundleDir, and the static and public copies can write outside the bundle.

Validate path.resolve(standaloneRoot, rel) with isWithin(standaloneRoot, ...). When relativeAppDir is derived from manifest.tracingRoot, also reject an appDir outside manifest.tracingRoot. Add a regression test for a path that passes the current appDir check but escapes standaloneRoot.

Proposed boundary check
-  if (path.isAbsolute(rel) || !isWithin(appDir, path.join(appDir, rel))) {
+  const resolvedStandalonePath = path.resolve(standaloneRoot, rel);
+  if (path.isAbsolute(rel) || !isWithin(standaloneRoot, resolvedStandalonePath)) {
