Media Trust Tools

Four macOS apps and a CLI tool for media integrity — copy, verify, and prove it.

Current stable: v2.1.7 (Build 5). Testing: v2.1.8 Build 8.

Version History (since v2.1.6)

v2.1.8 Build 8 (testing) — Post-cancel UX: "Reveal Receipts" and "Reveal Manifest" buttons appear in the action bar after a cancelled copy. Inline subfolder prefix field on the main view for quick tagging (e.g. "2.1.8_b6") without opening Settings.

v2.1.8 Build 6 — Fixed CopyTrust cancellation discarding partial file counts from session manifest. Manifest now also written to local logs folder. Drop Verify export-only UI: artifact rows show exported files with "Exported" badge, auto-reveal on completion, "Reveal Manifest" button after cancel. JSON keys differentiated: CopyTrust uses filesCopied, Drop Verify uses filesVerified.

v2.1.8 Build 5 — Session manifest persistence: structured JSON manifest written after every CopyTrust ingest and Drop Verify run, recording all verified, skipped, and failed files with reasons. Partial manifests saved on cancellation. New SkippedFileEntry / FailedFileEntry types in CopyCore with structured error capture in the copy loop.

v2.1.8 Build 4 — Drop Verify: read-only media detection with automatic export fallback. Cancel button and determinate progress bar during scanning/hashing.

v2.1.8 Build 3 — Volume Pool stays visible during copy sessions (collapsible disclosure triangle instead of hidden). Sources panel also collapsible. "End Session…" button renamed to "Review Summary…" for clarity.

v2.1.8 Build 1 — UI and receipt improvements.

• Smart video thumbnail frame selection — samples at ~17%/50%/83% instead of 0%/33%/66% to avoid black lead-in frames. Grid contact sheets sample at 50% (mid-point). Applies to both CopyTrust and Drop Verify.
• Phase timing in receipts — copy, verification, and artifact durations per destination with throughput (e.g. Copy: 04:32 @ 620 MB/s). JSON and plaintext.
• Collapsible panels — verification, completed sources, and log panels collapse with disclosure triangles. State persists across sessions.

v2.1.7 (stable) — Critical memory reduction across 5 builds. A 168 GB camera card that previously crashed the Mac at 118 GB RAM now copies at under 400 MB. Validated with a 4-hour, 390+ GB stress test.

v2.1.6 — Xsan (Fibre Channel SAN) volume detection in volume browser. Fixed network volume free space underreporting on SMB/NFS by cross-checking statfs, statvfs, and FileManager resource keys.

CopyTrust

Multi-source, multi-destination copy tool designed for camera card ingest but capable of copying any folders and files. Queue multiple cards, walk away, come back to verified results.

• Volume browser and Volume Pool for fast source/destination setup
• Destination preset groups for one-click restore of saved destination sets
• Per-destination preflight checks (free space, write permissions, reachability)
• Post-copy verification with xxHash64 (None / Quick / Full)
• MHL v1.1 hash list generation — compatible with OffShoot, Silverstack, ShotPut Pro, YoYotta
• MHL import verification — drag-and-drop any .mhl to re-verify destination files
• Auto-advance multi-source copy with per-card subfolder naming
• Contact sheet PDF (row or grid layout) and EXIF metadata CSV after each ingest
• Session receipts (JSON + TXT), per-ingest logs, and optional export to a separate folder
• Verify panel: Deep Compare Files, Compare Browser, Copy Missing, Retry MHL Export
• Safe-to-eject flow after successful transfer

See CopyTrust_UserGuide.md for the full workflow and settings reference.

Drop Verify

Single-folder drag-and-drop verification. Drop a folder and generate trust artifacts — no copy, no session, no setup.

• Media-only recursive scan with configurable exclusion patterns
• Generates MHL, contact sheet PDF (row or grid), and EXIF metadata CSV
• Writes artifacts into the folder and/or mirrors them to an export folder

See DROP_VERIFY_README.md and DROP_VERIFY_USER_GUIDE.md.

MHL Verify

Standalone MHL verification. Load any .mhl file and verify whether the media files still match.

• Re-check copies, archive restores, and handoff deliveries
• Works with MHLs from Drop Verify, CopyTrust, OffShoot, Silverstack, or any MHL-capable tool

Folder Copy Compare

The original tool that started the suite — a simple "did the copy work?" sanity check. Drop two folders and get an honest answer.

Use after copying with CopyTrust, Archiware P5 Sync, a Finder copy, rsync, Hedge, ShotPut Pro, or any other tool.

• Quick Scan (name, size, date) or Full Scan (xxHash64 / SHA-256 content hashing)
• Per-file comparison: missing, extra, different, identical
• Copy All Missing to sync differences, then Refresh to re-verify
• MHL v1.1 generation and verification from either compared folder
• Standalone app — no ingest session, no receipts, no artifacts

See FOLDER_COPY_COMPARE_README.md and FOLDER_COPY_COMPARE_USER_GUIDE.md.

mhl-tool (CLI)

Command-line tool for creating and verifying MHL v1.1 manifests. Same MHL engine as CopyTrust and Drop Verify, built for the terminal.

• mhl-tool create <folder> — hash files and write an MHL manifest
• mhl-tool verify <folder> — verify files against MHL(s), auto-discovers _Receipts
• Media-only (default) or --all-files mode
• JSON output for scripting, quiet mode for CI
• Reads MHLs from any tool (OffShoot, Silverstack, ShotPut Pro, YoYotta)
• Signed, notarized .pkg installer for distribution

See MHLToolPackage/README.md for command reference and MHLToolPackage/docs/USER_GUIDE.md for workflows.
