Specification loading, persistence, indexing, caching, startup, and frontend enqueueing pass default names and definition IDs consistently. Tests cover symlinked and resolved DAG paths. ChangesDAG entry naming
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The change preserves authored names for symlinked DAGs across listing, scheduling, and execution, while continuing to read from resolved targets. A bounded edge case remains for whitespace-surrounded fallback names in error paths, which can produce inconsistent DAG identities; the PR is otherwise mergeable with explicit owner awareness or follow-up.

Addressed the valid outside-diff cache finding in b7da15d as well. Metadata cache identity now includes both the DAG entry path and resolved target while freshness still follows the target file, and a regression test covers two differently named symlinks sharing one nameless target. The docstring-coverage notice is informational rather than a missing API contract: the new exported cache method has Go documentation, while the other reported declarations are private helpers or tests. No comment-only churn was added. |

Summary
Root cause
External DAG symlink support changed indexing, metadata, and execution reloads to use the resolved target path. The spec loader also derives a missing DAG name from the path it loads, so Nix/store and dotfile target basenames leaked into DAG identity. Long target names then exceeded the 40-character DAG-name limit, and content-addressed hashes made names unstable across edits.
Impact
A symlink such as
wiki-digest.yml -> /nix/store/<hash>-hm_wikidigest.ymlnow remainswiki-digestthroughout listing, details, scheduling, and enqueue. The resolved target remains authoritative for reads, relative-file resolution, and cache invalidation.Testing
make fmtmake lintmake test(13,669 tests passed; 37 environment/platform-specific tests skipped)Closes #2578
Summary by cubic
Preserves DAG names from symlink entry files and isolates metadata cache by entry. Previously, missing names were derived from the resolved target path and cached by target, causing long/unstable names and cross-entry bleed; now the default name uses the entry basename and metadata is cached per entry.
spec.WithDefaultNameand applies it to metadata-only loads, load-error DAGs, index build, repository details/update, and CLI start (env-provided definition ID) so resolved-target loads retain the entry identity.dagindex.IndexVersionto 4; indexes built with target-derived names are invalidated and rebuilt.entryPath + "\x00" + resolvedPath, and update/delete invalidate using this key, so multiple entries pointing to the same target don’t share cached metadata or names.enqueueDAGRunaccepts adefinitionID; callers ininternal/service/frontend/api/v1pass the entry identity (reschedule uses the prior definition), so runs retain their originating definition.Written for commit b7da15d. Summary will update on new commits.
