fix(prisma-cloud): wait for environment updates before deployment

[sampolahtinen]

Linked issue

Design brief: #281.

Summary

Compute snapshots environment variables when a deployment is created. An update to an existing Composer input document could race with replacement deployment creation, leaving the new deployment with old configuration and missing required fields.

Changes

• Preserve dependencies on whole environment resources in appAfterEnvironment, so deployment creation waits for pending value updates even when variable IDs stay unchanged.
• Add lifecycle regressions using the real Alchemy planner and Prisma providers with an in-memory API and a controlled update gate. Cover changed input, newly required fields, drift repair, mixed variables, failed writes, and unchanged deployment reuse.
• Update the deployment guide and ordering documentation to explain the dependency on completed writes.

Why

Alchemy can resolve a persisted variable ID while its value update is pending. Referencing the whole resource retains the ordering dependency. The edge stays on the deployment's app input so artifact replacement detection continues to work.

Testing performed

• Before the fix, four of the five lifecycle scenarios failed. All five pass with the fix.
• pnpm format, pnpm build, pnpm typecheck, pnpm lint, and pnpm lint:deps passed. Lint reports existing warnings outside the changed files.
• pnpm --filter @internal/lowering test: 192 passed.
• bun test packages/1-prisma-cloud/1-extensions/target/src/__tests__/control-lowering.test.ts: 56 passed.
• CodeRabbit reviewed all five changed files and reported no findings.
• pnpm test was attempted but stopped in the local-target PostgreSQL emulator suite: the sandbox denied writing its machine-global lock file. The affected suites passed independently as listed above.

Checklist

• All commits are signed off 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 for the behavior change.

Notes for the reviewer

This implements the environment ordering proposal in #281. Readiness checks remain a separate design. Validation uses an in-memory API; no live deployment was performed.

Summary by CodeRabbit

• Bug Fixes

  • Deployments now wait for environment-variable updates to complete before creation.
  • Deployment environment variables are captured consistently, including pending updates and replacements.
  • Existing deployments continue using their original environment snapshot when variables change later.

• Documentation

  • Updated deployment guidance and design documentation to explain environment-variable timing and deployment ordering.

• Tests

  • Added coverage for environment updates, replacements, drift repair, added variables, and failed updates.

Walkthrough

Deployment ordering now depends on complete environment variable resources instead of stable IDs. Lifecycle tests cover updates, new variables, drift repair, snapshots, idempotence, and failed updates. Design records and deployment documentation describe the updated ordering and creation-time environment capture.

Merge Risk: 🔵 Low · up to 725ff

Deployments now wait for completed environment-variable writes before capturing configuration. The remaining risk is limited to an outdated design-diagram label, so the change is otherwise mergeable with a documentation follow-up.

Update the diagram to show whole-resource dependencies.

These edges still use the label id ref. Lines 184-185 and Lines 206-209 now specify complete EnvironmentVariable resource dependencies. Rename these labels to resource ref or equivalent.

Also applies to: 172-172
