Overview

Package componenttypes defines shared types for component management. These types are used across lockfile, userconfig, catalog, and conformance packages to provide a consistent interface for component metadata.

Package componenttypes defines shared types for component management. This file defines exit codes and error codes shared across all component types.

Package componenttypes defines shared types for component management. This file defines type-safe validated names that can only be constructed through validation functions, making validation bypass impossible.

Package componenttypes defines shared types for component management. This file defines binary name prefixes per C-001 naming convention.

  2. Missing digest: allowed only with InsecureAllowUnpinned, never in frozen mode
  3. Frozen mode: all components must have a digest

CopyPlatforms creates a defensive copy of a platforms map.

func InsecureAllowUnpinnedFromEnv 

func InsecureAllowUnpinnedFromEnv() bool

func WarnUnpinnedExecution 

func WarnUnpinnedExecution(w io.Writer, kind ComponentKind, name, path string, fromPATH bool)

WarnUnpinnedExecution prints a warning when executing an unpinned component. This is called when InsecureAllowUnpinned is true and a component is not pinned.

VerifyOptions controls component execution security. These options are shared across all component types (collectors, tools, remotes, utilities).

The security model follows the collector pattern:

  • By default, all components must be pinned in lockfile with digest verification
  • --frozen mode (CI) requires all components to be pinned
  • --insecure-allow-unverified permits components installed with --insecure-skip-verify
  • --insecure-allow-unpinned permits components not in lockfile (for development)

DefaultVerifyOptions returns secure defaults for component verification. All security checks are enabled; no insecure modes allowed.

func VerifyOptionsFromEnv 

func VerifyOptionsFromEnv() VerifyOptions

VerifyOptionsFromEnv returns options with environment variable defaults applied. Reads EPACK_INSECURE_ALLOW_UNPINNED to set InsecureAllowUnpinned.
