LoadConfigForCDto avoid state mutation on failure.The current implementation sets
CDRegioneven whenLoadDefaultConfigreturns an error (line 41 executes before the error is returned). Additionally, whenCDRegionis empty, passing it as an empty string toLoadDefaultConfigdoesn't trigger normal AWS region resolution—instead, it propagates the empty value.Fall back to
LoadConfigForAppwhenCDRegionis unset (which validates the region and handles fallback logic), then only callLoadDefaultConfigwith a confirmed non-empty region. This ensures state mutations only occur on success.💡 Proposed fix

Align cfnOtherRegion config/env before SetUp to avoid unintended stack updates.
cfnOtherRegion runs with default RetainBucket/Spot and no DockerHub envs, but SetUp uses those values to update the stack. That can both mutate the existing stack and make the equality assertions for RetainBucket/Spot flaky. Mirror the main test’s config/env (or use a read‑only path) before calling SetUp.

Consider using LoadConfigForApp for consistency with Stop().
Info() currently uses LoadConfigForCD while Stop() uses LoadConfigForApp for the same AwsEcs struct. Although both regions are initialized to the same value in AwsEcsCfn (line 48 of cfn/setup.go: "assume CD runs in the same region as the app"), this inconsistency is semantically confusing. Since Info() is only called from AwsEcsCfn.GetInfo() context and operates on the CD cluster, the current implementation works, but consider aligning with Stop() for clarity, or add a comment documenting why Info() requires LoadConfigForCD when both region configs are identical in practice.

Recreate the CloudFormation client if CDRegion changes.
The CloudFormation client is bound to the region at creation time (line 103). However, describeStacksAllRegions (line 109) can update a.CDRegion when discovering the stack in a different region. Subsequent calls to UpdateStack (line 133) and the waiter (line 150) will then operate against the wrong region, causing failures.
The proposed fix is necessary: after describeStacksAllRegions returns, recreate the CloudFormation client if a.CDRegion has changed to ensure all subsequent operations target the correct region.

Avoid package-level quotaClient mutation during deploys.
Assigning a shared client per request can race and leak config across concurrent deployments. Prefer storing it on ByocAws or passing it into validateGPUResources.

Fix concurrent writes to es.err and loop variable capture in goroutine.
The es.err field is written by multiple goroutines without synchronization, creating a data race that can cause undefined behavior and lost errors. Additionally, the loop variable s is captured by the goroutine closure; while Go 1.22+ fixed per-iteration scoping, explicit parameter passing is the clearer, safer practice.
Guard error assignment with a mutex and pass s as a goroutine parameter to prevent capture issues.

- Around line 18-23: The LogType bit values were shifted by introducing
`LogTypeCD = 1 << iota`, altering `LogTypeRun` and `LogTypeBuild` numeric
values; revert to explicit constants (e.g., set `LogTypeCD = 1`, `LogTypeRun =

compatibility, and add `LogTypeCD` to the `AllLogTypes` slice used by `String()`

Guard against empty CDRegion from unresolved LoadDefaultConfig.
Code paths in byoc.go:136 pass empty region to New(), which initializes CDRegion to empty string with a comment "default region". However, LoadConfigForCD does not validate that cfg.Region is populated after calling LoadDefaultConfig, unlike LoadConfigForApp which explicitly errors on empty region. If LoadDefaultConfig returns empty cfg.Region, then CDRegion remains empty and propagates into MakeCdARN, creating malformed ARNs.
Add validation to ensure a region is resolved:
func (a *AwsEcs) LoadConfigForCD(ctx context.Context) (awsx.Config, error) {
cfg, err := aws.LoadDefaultConfig(ctx, a.CDRegion)
+ if err != nil {
+ return cfg, err
+ }
// If we don't have an region override for CD, use the current AWS region
if a.CDRegion == "" {
a.CDRegion = aws.Region(cfg.Region)
}

Use explicit bit positions to preserve Run and Build values.
Inserting LogTypeCD = 1 << iota shifts subsequent values: Run moves from 2→4, Build from 4→8. This breaks compatibility with any persisted or serialized log type values that previously stored Run=2 or Build=4. Use explicit bit positions instead to maintain backward compatibility:
const (
LogTypeUnspecified LogType = 0
LogTypeCD LogType = 1 << 0
LogTypeRun LogType = 1 << 1
LogTypeBuild LogType = 1 << 2
LogTypeAll LogType = 0xFFFFFFFF
)Additionally, LogTypeCD is missing from the AllLogTypes slice, which will cause it to be omitted from the String() output when combined with other flags (e.g., LogTypeCD | LogTypeRun will only display "RUN"). Add it to the slice.

In `@src/pkg/logs/log_type.go` around lines 18 - 23, The LogType bit values were
shifted by introducing `LogTypeCD = 1 << iota`, altering `LogTypeRun` and
`LogTypeBuild` numeric values; revert to explicit constants (e.g., set
`LogTypeCD = 1`, `LogTypeRun = 2`, `LogTypeBuild = 4`, keep `LogTypeAll =
0xFFFFFFFF`) to preserve backward compatibility, and add `LogTypeCD` to the
`AllLogTypes` slice used by `String()` so the CD flag appears when combined with
other flags (e.g., `LogTypeCD | LogTypeRun`).

Description
Currently, the CD CloudFormation stack has to be in the same region as the region the app will be deployed too. This now requires a CD stack per region.
This PR allows us to use the CD stack in any region to deploy to app, to other regions.
