Bracket symlink target observation with the identity captured during enumeration. Report replacements and disappearing links as changed, and keep cancellation and I/O mapping at one owner boundary.
Remove duplicate target-error wrappers and unreachable external-target handling. Validation: reference reader filesystem suite passes, including deterministic replacement during observation.
Require a caller-owned artifact resource scope for source traversal and Git metadata reads. Preserve cancellation, filesystem reasons, partial entries and bytes, and cleanup observations through import and the CLI. Transfer exact failed file owners at regular-file admission and close boundaries, including multiple failures encountered by Git reference resolution.
Validation: 169 focused tests passed across 26 files; two Windows-only cases skipped. Build, typecheck, lint, formatting, knip, architecture guards, discovery and docs checks passed.
BREAKING CHANGE: Reference source readers and imports require an ArtifactResourceScope. VCS metadata reads return Result, and CLI import failures include observed details and partial evidence.
Inspect each entry without following links before applying directory-only patterns. Retain the winning rule and original entry path while pruning excluded directories before reading their children.
Validate directory exclusions, negation, symlinks, explicit secret rules, and compiled CLI provenance alongside reference reader failure and cancellation coverage.
