Install Dependencies

Install missing forensics CLIs based on environment-check results, grouped by package manager.

When to use

• After environment-check reports gaps
• During initial setup (called by onboard)
• After host environment changes (new Python, node, system packages)

Inputs to gather

• Optional: path to state/env.json (defaults to plugin's standard location)
• Confirmation per package-manager group before proceeding

Procedure

1. Read state/env.json (or run environment-check if absent).
2. Identify missing tools and group by installer:
   • apt: exiftool, mediainfo, mat2, rclone, awscli
   • pip: opentimestamps-client, bagit
   • npm: single-file-cli
   • cargo (optional, if b3sum not in apt): b3sum
   • brew (macOS only, if applicable)
3. For each group, present the install command and request user confirmation.
4. Run apt groups with sudo apt-get update && sudo apt-get install -y <pkg> …
5. Run pip groups as user (or with python3 -m pip install …)
6. Run npm groups as user (prefer npm install -g … or npx)
7. Run cargo / brew as per platform defaults.
8. After all installs, re-run environment-check and diff the new state/env.json against the old.
9. Report summary: newly available tools, any still-missing, and next-step guidance.

Output / side effects

• System packages installed (apt: system-wide; pip/npm: user or global scope as appropriate).
• state/env.json updated with new tool availability.
• User sees a diff of before/after tool status.

Safety / constraints

• Require explicit user confirmation before running sudo apt-get.
• Do not attempt to install if a tool already exists (skip silently).
• mat2 may require apt install mat2 plus python3 -m pip install … for extras; check package notes.
• If installation fails, report the error and do not mask it; suggest manual troubleshooting.
