Clean dissolution. The approach is exactly right:

• FileEntry stays as the authoritative carrier (the broader Layer-1 definition in the original comment prose)
• FileClassification becomes a type alias — type FileClassification = FileEntry
• One record, one authority, but the semantic name for "what probe returns" is preserved for readability at call sites

Per feedback_naming_is_aliasing ("named types are namespaces; the compiler sees through names"), this is the canonical pattern. Better than deleting FileClassification outright — it keeps the API-surface name meaningful for the dsl/std/resources.dag consumer without carrying a second record shape.

Caller check

Verified the only live consumer is dsl/std/resources.dag (import std.filesystem { FileClassification } + output { classification: FileClassification }). That import + usage naturally resolves through the alias — no caller update needed. Docs references in docs/lens-library-design.md and docs/modeling/worked-examples-*.md stay consistent.

Minor note (non-blocking)

Two small things to consider for a followup if you're back in this area:

1. ROADMAP entry can be closed — once this merges, the P2 "FileClassification / FileEntry duplicate" bullet in ROADMAP.md is resolved. Good followup is to delete the bullet (or add a DONE: PR #596 marker) as part of the next ROADMAP maintenance pass.
2. lens-library-design.md explicitly names this as a target example — the mention is now stale (alias done). Also a followup, not this PR's scope.

Ship criteria

• +11/-21, single-file, isolated to std/filesystem.
• CI should pass cleanly (markdown + .dag syntax only).
• Merge when fmt / ci / v3 green.

One down on the P2 list — nice focused scope.

✅ Review (blocking: 0, non-blocking: 1+/1-)

Non-blocking — Strengths

• dsl/std/filesystem.dag Mixed (.dag models + docs): collapsing FileClassification to type FileClassification = FileEntry removes the parallel carrier while preserving the probe-surface name, which is the right single-authority shape.

Non-blocking — Improvements (fix in-PR if easy, else defer to roadmap)

• docs/lens-library-design.md The new "intentional aliases excluded per policy" claim makes alias handling load-bearing for lens_structural_duplicates, but section 2.1 still does not define how the lens distinguishes sanctioned aliases from true duplicates; document that rule in the lens-library implementation lane before the lens lands.

✅ The substantive model change is clean, the doc updates mostly track it accurately, and I found no blocking issues in the PR.

⚠️ Review (blocking: 1, non-blocking: 0+/0-)

BLOCKING (1)

Root Cause

• docs/lens-library-design.md The policy only distinguishes transparent alias vs nominal declaration, but the missing split is alias-vs-canonical-name exclusion vs alias-vs-alias duplicate detection; choose one rule and align the examples, tests, and success criteria to it.

ROADMAP — Verified

• P2 FileClassification/FileEntry duplicate: This PR really does collapse the duplicate carrier to one FileEntry record plus a namespace alias, so removing that debt line from ROADMAP.md is accurate.

⚠️ The FileClassification/FileEntry substrate cleanup is good, but the new lens alias policy still contradicts its own target set and should be clarified before it guides implementation.

⚠️ Review (blocking: 1, non-blocking: 1+/0-)

BLOCKING (1)

Root Cause

• docs/lens-library-design.md v3 lowers each where predicate to a fresh declaration and proves equivalence structurally, so a canonical_refinement_id here would either add a parallel authority or miss same-shape peers; define Rule 2 on structural predicate equivalence or fingerprint and align the algorithm plus test text to that same fact.

Non-blocking — Strengths

• dsl/std/filesystem.dag Collapsing FileClassification to a FileEntry alias removes the duplicate substrate carrier while preserving the probe-surface API name for callers.

ROADMAP — Verified

• P2 FileClassification/FileEntry duplicate: Removing the debt bullet is accurate because this PR replaces the second record with a namespace alias rather than a parallel carrier.

⚠️ The filesystem cleanup is good, but Section 2.1 still needs one consistent refinement-identity authority before it is safe to guide the duplicates-lens implementation.

✅ Review (blocking: 0, non-blocking: 2+/0-)

Non-blocking — Strengths

• docs/lens-library-design.md The new Rule 1 / Rule 2 split gives lens_structural_duplicates one coherent single-authority story: pure aliases fold into the canonical carrier, while peer refinement aliases are still surfaced.
• dsl/std/filesystem.dag Collapsing FileClassification into FileEntry plus a namespace alias removes the duplicate substrate carrier without losing the probe-surface API name.

ROADMAP — Verified

• P2 FileClassification/FileEntry duplicate: Removing the debt bullet is accurate because this PR leaves one record in std/filesystem.dag and demotes FileClassification to an alias instead of a second authority.

✅ The load-bearing ambiguities from the earlier review are addressed, and the filesystem cleanup plus roadmap update are consistent with the thesis and current v3 refinement behavior.

Non-blocking — Improvements (fix in-PR if easy, else defer to roadmap)

• docs/lens-library-design.md The new §2.1 prose correctly demotes NonEmptyStr/NonEmptyString to an audit-era example, but later changed sections still describe it as a current expected repo finding even though dsl/std/types.dag now only carries NonEmptyStr; tighten those examples before they become stale lens-test expectations.

✅ The duplicate-record substrate issue is fixed cleanly and the prior refinement-authority ambiguities are resolved; only the stale example inventory looks worth a follow-up.

4/4 green. FileClassification/FileEntry dissolution via type alias. Docs + ROADMAP updated cleanly. Per feedback_naming_is_aliasing — canonical pattern. Merge.
