Summary by CodeRabbit

New Features
- Added support for including asset files when publishing policies to a registry with the --assets option. Pulled policies now include their assets, which are available after pulling when options.relativepaths: manifest is set.
Bug Fixes
- Policy publishing now returns an error when it cannot resolve a file path or when a file is outside the configured file store, instead of continuing with incomplete file lists.

📝 Walkthrough

Walkthrough

The registry push flow accepts asset files, stores them under an asset media type, and resolves pushed file paths relative to the file store. The pull flow returns a PullResult containing manifests, values, secrets, and assets, and checks local existence for all four file categories.

Changes

OCI Policy Assets

Layer / File(s)	Summary
Push assets to the registry `cmd/manifest_push.go`, `cmd/root.go`, `pkg/core/engine/registry.go`, `pkg/core/registry/push.go`, `pkg/core/registry/var.go`, `pkg/core/registry/testdata/asset.sh`, `pkg/core/registry/pullpush_test.go`	The CLI accepts asset file paths and passes them through the engine to registry push. The push flow resolves file paths relative to the file store and adds assets with the asset media type. The tests include an asset push case.
Return pulled assets to policy loaders `pkg/core/registry/pull.go`, `pkg/core/engine/registry.go`, `cmd/root.go`, `pkg/core/compose/main.go`, `pkg/core/registry/pullpush_test.go`	`Pull` returns a `PullResult` with manifests, values, secrets, and assets. The pull flow checks local asset paths, and the CLI and compose callers read the result fields. Tests cover the result shape, path handling, and pulled asset files.

Merge Risk: ⚪ Minimal · up to 99a4c

No unresolved issue identified in the reviewed change; it is mergeable after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 99a4c

Asset publishing uses the existing registry credentials and publication controls, and the new push path rejects files lexically outside the selected store. Filesystem containment for symlinks and untrusted registry content still needs confirmation.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — A caller able to select policy files and publish with registry credentials can now include asset bytes in that policy. The observed path does not grant new registry credentials or change the existing overwrite decision.

Trust Boundaries and Controls

observed — Push-side containment checks relative path strings, not resolved symlink targets. On pull, registry-controlled layer titles are joined to the policy directory and checked for local existence without an explicit containment check. The title-handling pattern already applied to other file categories before this PR; whether the file-store dependency prevents an out-of-root read or write is unverified.

Resilience and Maintainability Implications

observed — Failures while adding files stop publication before packing. Once publication starts, references are processed independently; the partial-publication and retry limitation is inherited rather than introduced by the new asset category.

Hardening Proposals

proposed — Verify file-store symlink and extraction behavior, and enforce resolved-root containment for both asset inputs and OCI layer titles if that behavior does not provide it.

The description includes the issue number and a test command, but it does not describe the changes introduced by the pull request. The tradeoff and potential improvement sections are also left blank, and the manual-testing checklist item is missing.

Resolution

Add a brief summary of how the pull request stores and retrieves policy assets in an OCI registry. State the dependency on #8300 clearly. Complete the manual-testing checklist item and describe any tradeoffs or potential improvements, or state that there are none.

PushToRegistry, before resolving inputs or calling relativeToFileStore, and
return a contextual error if normalization fails. This ensures filepath.Rel
