Removes the stg deployment stage from the stage model and everything that existed only to serve it.

Why

Staging was dead infrastructure with a live hazard attached:

  • .github/workflows/deploy-stg.yml was disabled_manually on GitHub, with no run history.
  • api-staging.maple.dev and ingest-staging.maple.dev do not resolve.
  • resolveHyperdriveRefId handed stg the production Hyperdrive config (ad4c487838594b89810b23e5fb14e129, "TEMPORARY … owner decision, 2026-07-14"). A staging deploy would have read and written the production customer database, and its alerting crons would have overlapped prod's. Deleting the stage deletes that hazard.

What changed

Stage model (packages/infra)

  • MapleStage is now prd | pr-<number> | dev.
  • parseMapleStage rejects "stg" explicitly. It is not enough to drop the case: stg matches the dev-stage pattern, so a --stage stg would otherwise have silently built a maple-*-dev-stg stack with an alchemy-managed Hyperdrive.
  • Dropped: the staging domain block, the staging MAPLE_ENVIRONMENT label, and the stg arms of resolveDatabaseMode, resolveHyperdriveRefId, resolveWorkerName and resolveAwsResourceName.
  • Service gates that were prd || stg are now prd: stageDeploysSandbox, stageEnablesReplayBlobs, stageDeploysElectric. stageDeploysIngest is prd || pr.
  • Every prd Hyperdrive config id is byte-for-byte unchanged, and a new test in stage.test.ts pins both ids plus the fact that nothing but prd gets one.

CI / scripts

  • Deleted .github/workflows/deploy-stg.yml.
  • Removed the staging leg (tinybird-cd-stg environment) from tinybird-cd.yml.
  • Removed alchemy:deploy:stg and alchemy:destroy:stg from package.json.
  • Fixed the staging GitHub Environment references in aws-probe.yml's and deploy-pr-preview.yml's role-trust notes, and in deploy-setup/build-ingest-binary headers.

Tests — expectations updated rather than dropped; the "staging maps to X" assertions became "this stage string is now rejected".

Docsdocs/infra.md's "Open item — staging points at production" section is now a resolved-by-deletion note; README.md's deploy table and stage grammar, CLAUDE.md, docs/persistence.md, docs/electric-sync.md and docs/local-mode.md updated.

Deliberately left standing

  • MAPLE_ALERTING_ALLOW_NONPROD / MAPLE_EMAIL_ALLOW_NONPROD — they still serve dev stages and PR previews. Only the comments that justified them by reference to staging changed.
  • The production ? standard-2 : standard-1 sizing in apps/sandbox/alchemy.run.ts. With the sandbox now prd-only the non-prd arm is unreachable, but it is a stage dial rather than a staging artifact; collapsing it is a separate call.
  • Every customer-facing use of the word "staging" — dashboard fixtures, query-engine test data, deployment.environment values in telemetry fixtures, the semconv docs, CLI flag help. That is user data, not our infrastructure.
  • apps/api/src/routes/v2/widget-summary.http.ts and friends, for the same reason.

Verification

  • bun run --cwd packages/infra test — 75 passed
  • bun run --cwd packages/alchemy-maple test, bun run --cwd packages/db test scripts/reset-preview-branch, bun run --cwd apps/api test src/routes/v2/integrations-origin, bun run --cwd apps/cli test, bun run --cwd apps/local-ui test src/lib/constants
  • bun turbo typecheck filtered to @maple/infra, @maple/db, @maple/api, @maple/backend, @maple/alerting, @maple/sandbox, @maple/cli, @maple/local-ui, @maple-dev/alchemy; plus tsc -p tsconfig.alchemy.json for the root stack
  • oxfmt --check and oxlint clean on the touched trees

Follow-up for the operator

Nothing in this repo can remove the external remnants: the staging and tinybird-cd-stg GitHub Environments, the staging Infisical environment, the staging subject in the AWS deploy role's trust policy, and any leftover maple-*-stg Cloudflare workers or AWS resources. They are inert once this merges, but worth reaping.

Summary by CodeRabbit

  • Breaking Changes

    • Removed the staging (stg) deployment stage and workflow.
    • Staging-specific commands, environments, domains, database branches, and infrastructure resources are no longer supported.
    • Staging identifiers are now rejected; deployments use production, development, or PR preview stages.
    • Tinybird deployments now target production environments only.
  • Documentation

    • Updated deployment, infrastructure, local development, persistence, and operational documentation to reflect production and preview environments.
    • Updated staging examples and references to production or preview URLs.

Staging had been disabled in GitHub with no run history and neither
api-staging.maple.dev nor ingest-staging.maple.dev resolved, so the only
thing the stage still cost was a compliance hazard: resolveHyperdriveRefId
handed `stg` the production Hyperdrive config, which would have had staging
workers read and write the production customer database and staging alerting
crons overlap prod's.

`MapleStage` is now prd / pr-<number> / dev. `parseMapleStage` rejects "stg"
explicitly rather than letting it fall through to the dev-stage pattern it
matches — a `--stage stg` that quietly built `maple-*-dev-stg` is not the
failure anyone typing it wants.

Removed with it: the staging domain block, deploy-stg.yml, the staging leg of
tinybird-cd.yml, the alchemy:deploy:stg / :destroy:stg scripts, and the
prd/stg service gates now reading prd only (sandbox, R2 replay blobs,
Electric, AWS ingest). Every prd Hyperdrive config id is unchanged.

MAPLE_ALERTING_ALLOW_NONPROD and MAPLE_EMAIL_ALLOW_NONPROD stay — they still
serve dev stages and previews; only the comments citing staging changed.

📝 Walkthrough

Walkthrough

The staging deployment stage is removed from stage parsing, infrastructure resolution, CI workflows, deployment scripts, tests, and documentation. Production, PR preview, and development stages remain documented and validated.

Comment thread apps/api/scripts/BENCH.md Outdated
Comment thread CLAUDE.md Outdated
bench:fetch mines production traces, so the re-run step has to name production rather than "deploy the change". And prd is now the only stage with a PlanetScale branch at all — PR previews are deployed but resolveDatabaseMode returns "none" for them — so "one branch per deployed stage" no longer describes anything.
