Adds a build-tagged (//go:build e2e) suite under e2e/ that runs the compiled cac binary as a subprocess against the postmance-dev test tenant: - TestImportAndPull: create a workspace via `push --method import`, pull it back - TestImportRoundTrip: change the workspace name, re-import, pull into a fresh dir, and assert the change persisted (the contract assertion a mock can't make) Tenant constraints handled: workspaces are created via import (the client lacks server-admin rights), mutations use import (the rfc7396 patch endpoint is forbidden for this client), and runCAC retries the config API's burst rate-limit (request_forbidden) with backoff. Tests run sequentially. Credentials come from CAC_E2E_* env vars (gitignored .env.local locally, secrets in CI); .env.local.example documents them. CI runs on merge_group via .github/workflows/e2e.yaml. Env parsing uses subosito/gotenv (already in the module graph via viper). Workspace deletion is not yet implemented; runs leak e2e-* workspaces.

What
Adds a real-server end-to-end suite (
e2e/, build-tagged//go:build e2e) that drives the compiledcacbinary as a subprocess against thepostmance-devtest tenant. It targets the tool↔API contract — the class of bug a hand-written mock can't catch.Two tests:
TestImportAndPull— create a workspace viapush --method import, pull it back, assert the server file is written with the expected name.TestImportRoundTrip(core contract test) — change the workspace name locally, re-import, pull into a fresh dir, assert the change persisted remotely.How it runs
make test-e2elocally, orgo test -tags e2e ./e2e/.... The defaultgo test ./internal/...is unaffected (build tag).CAC_E2E_*env vars — a gitignored.env.locallocally (see.env.local.example), repo secrets in CI..github/workflows/e2e.yamlruns onmerge_groupso it executes once on the to-be-merged HEAD; intended as a required check via merge queue.Tenant constraints handled (discovered via live testing)
