📝 WalkthroughWalkthroughChangesThe pull request adds a reusable composite action for incremental S3 deployment. It hashes local files, preserves protected paths, sets text metadata, skips unchanged uploads, and optionally invalidates CloudFront. Website workflows now use the action. S3 deployment

never reach upload_changed while unprotected changes retain current behavior.

Preserve CloudFront wildcard paths.
When a caller sets cloudfront-distribution-id, Bash expands the default /* into runner filesystem paths before aws cloudfront create-invalidation runs. The invalidation then does not cover the full site. Current repository callers leave this optional branch disabled.
Split the documented space-separated input into an array, then expand the array with quotes.

Exclude protected objects from the bootstrap metadata copy.
The preceding s3 sync excludes protected paths, but this recursive S3-to-S3 copy does not. A protected text object such as assets/refarch/handoffs/example.json matches the extension filter and is copied onto itself with --metadata-directive REPLACE. That overwrites its externally managed metadata even though the production workflow marks that prefix as protected. S3 permits same-key copies with REPLACE, and unspecified metadata is not preserved. (docs.aws.amazon.com)
Add every protected_patterns entry as a final --exclude to this command, or stage and upload only managed local text objects.

Fail when S3 reports per-object delete errors.
DeleteObjects can return HTTP success with an Errors list for individual keys. run_aws checks only the CLI exit status. This function then returns and Line 280 uploads a manifest that no longer tracks the undeleted keys. Future deployments will not retry them. (docs.aws.amazon.com)
Request JSON output, parse Errors, and raise before upload_manifest.

Exclude protected paths from the managed manifest and changed uploads.
The production workflow passes pr-* and assets/refarch/handoffs/* as protected patterns to the S3 deploy action. build_manifest still records matching local files, and manifest_diff filters protected paths only from deleted. A changed protected file therefore reaches stage_changed_files and upload_changed, which can overwrite the externally managed object in the production S3 root.
Exclude protected paths from the managed manifest or from changed uploads, in addition to excluding them from deletions.

Summary
Safety
The first run bootstraps existing destinations with the current sync behavior and records the manifest. Later runs delete only objects previously managed by the same deployment prefix. The manifest advances only after all changes succeed.
Validation
Expected savings: approximately $70-80/month.
