Alpha 0.0.93 / Driver B190 — engineering prerelease

This download includes the rewindDV application, independent Driver B190, and the native arm64 rewinddv CLI / stdio MCP client. App build188 and driver build190 are separate identities. All three executables are freshly built from the exact reviewed public source and signed ad hoc with hardened runtime.

• Saved raw DV25 playback opens with frame-local reads without automatic whole-file indexing. Rapid scrubbing prioritizes the latest request, and selected-frame metadata follows gesture release. Exact coordinates and full-file source assessment remain explicit scans; preview duration and ordinals are estimates.
• Surgery makes separate byte-preserving DV assemblies with source mappings, hashes and reviewed frame ranges.
• 66 local CLI/MCP tools control playback, Surgery, archive inspection, evidence maps, review, multi-pass comparison and recovery-plan preparation through the running app's existing operation guards. Start the app and accept its alpha notice before using ./rewinddv status or ./rewinddv mcp. External source/destination paths require a GUI sandbox grant for the current session. Driver activation and physical supervised recovery remain interactive.
• The automation bridge bounds socket client I/O, keeps it off the app main thread, rejects malformed MCP arguments, and retains operation locks and supervised STOP rules.

Known limits: mixed NTSC/PAL seeking can reach a position while the inspector remains unassociated with the displayed source frame. This remains unresolved. Session-scoped sandbox grants may need renewal after app restart. HDV playback, physical PAL/HDV capture, natural end-of-tape, full-tape completion, broad hardware compatibility and live driver unload/hot replacement remain unqualified.

Ad-hoc signed, not notarized. Driver installation requires disabling SIP, which reduces macOS security. Use a backed-up dedicated test Mac and read INSTALL.md and UNINSTALL.md. No developer account, device registration, profile download or local re-signing is required. Ad-hoc signing checks integrity; it is not an Apple-verified publisher or normal notarized SIP-on distribution. Offline playback, Surgery and inspection do not require driver activation.

This exact public package has not been installed or physically qualified. The public-source build passes 273 Swift Testing cases, 14 XCTest cases, native app/driver/CLI compilation and release/status/disclosure regressions. Restored-ZIP signatures, architectures, modes, manifest and hashes are verified separately. These are software checks. Earlier Alpha 0.0.89 / B190 development-signed evidence remains limited to bounded NTSC DV captures, normal capture STOP and re-entry on one Sony HVR-M15U / Apple silicon / macOS27.0.1 setup; it is not new qualification of this download.

Normal capture STOP keeps the driver loaded. Live extension disable, hot replacement and reboot-free removal remain unqualified. Finish capture, stop tape motion and use the documented shutdown/restart maintenance procedure. Do not use extension disable as a capture-session STOP.

• Apple silicon: app and CLI arm64, driver arm64e. App deployment floor macOS26; source toolchain Xcode27. Intel is unsupported.
• Supported controller: PCI11c1:5901 with the tested Apple Thunderbolt-to-FireWire adapter chain; USB-to-FireWire cables are not a substitute.
• Exact public package source: 482cf2fcdee763535dd5e69a658886accce20f36.
• ZIP SHA-256: 1d72e36932700230d2be98e66dc8718e514761576a9e2c6ae867861cdbff23e8.

Download the ZIP, its checksum sidecar, manifest.json and provenance.json from this release. Verify the checksum and signatures before use. Original captures are never replaced. Matching saved-byte hashes establish byte consistency, not flawless audiovisual content or uninterrupted hardware transport.
