Summary

  • Adds ~70 targeted tests for deploy.go and stack.go handlers: multipart tarball parsing, tier-cap 402 walls, env-vars merge + POSIX key validation (incl. empty-string deletes + 64KiB cap), vault-ref resolution, needs:-resource resolution (resolve/inject/cross-team/deleted), promote approval flow (consumeApprovedPromote — all branches), dev-env promote execution, two-step email-confirmed deletion (confirm/cancel success + cross-team + 404), and the async runDeploy/runStackDeploy/runStackRedeploy goroutine success+failure branches via injected compute/stack-provider doubles and closed-DB fault paths.
  • Adds a test-only SetStackProvider setter on StackHandler (mirrors the existing SetComputeProvider on DeployHandler) plus export_test.go wrappers so external handlers_test tests can exercise unexported helpers without an import cycle through testhelpers.

Coverage

  • deploy.go: ~71% → ~86%
  • stack.go: ~62% → ~77%
  • Remaining uncovered paths are dominated by k8s-constructor init branches (unreachable without a live cluster), rand.Read failure, and deep best-effort defensive error tails (audit goroutines, teardown-failure warns). The 95% target was not fully reached on stack.go; the remaining gap is largely structurally unreachable in unit tests.

Test plan

  • All new tests pass: go test ./internal/handlers -run '<new tests>' -count=1 -p 1
  • go build ./... + go vet ./internal/handlers clean
  • CI green on the coverage workflow

Add ~70 targeted tests for the deploy.go and stack.go handlers covering
multipart tarball parsing, tier-cap 402 walls, env-vars merge/key-validation,
vault-ref resolution, needs:-resource resolution, promote approval flow
(consumeApprovedPromote), dev-env promote execution, two-step deletion
(confirm/cancel), and the async runDeploy/runStackDeploy/runStackRedeploy
goroutine success+failure branches via injected compute/stack-provider doubles
and DB-fault paths.

Adds a test-only SetStackProvider setter (mirrors SetComputeProvider) and
export_test.go wrappers so external tests can exercise unexported helpers
(truncateForAudit, resourceEnvKey, parseResourceToken, rewriteToInternalURL,
runDeploy, captureAutopsy) without an import cycle through testhelpers.

deploy.go ~71% -> ~86%, stack.go ~62% -> ~77%. Remaining uncovered paths are
k8s-constructor init and deep defensive error tails not reachable without a
live cluster.

Add gap-filling tests for deploy.go and stack.go error and edge branches:
manifest/tarball/token/env validation on /stacks/new, promote
invalid-body/env-mismatch/no-services/missing-image-ref/create-target paths,
copyVaultRefsForPromote no-op + skip-existing + per-key copy, stack
Redeploy/UpdateEnv merge+delete+cross-team, and closed-DB 503 arms for
stack UpdateEnv/Promote/Family. Lifts deploy.go ~82->83% and stack.go
~72->80%.

Add a real-DB test that pre-seeds a target stack in the same family so
Promote takes the updated_existing path — covering both the existing-service
image_ref update and the missing-service create branches.
