+## Overview of 3.0 "Auto-healing" or "Force Healing"
+
+In the past with the Nexus deleting files every day, we saw a need
+for rapid fully automatic healing for Wabbajack lists. This code was 
+brittle, quite complex, and hard to debug. However, these days with
+the Nexus no longer deleting files, we have an opportunity to simplify
+the process. 
+
+### Parts in play
+* List Validation service -  a GitHub action with some static storage, and rights to log into all our download soruces
+* Storage Server - the backing store behind the Wabbajack CDN consists of 3 storage spaces:
+  * Patches - a directory of files stored as `{from_hash_hex}_{to_hash_hex}`
+  * Mirrors - a directory of files in the CDN multi-parts format stored as `{file_hash_hex}`
+  * Authored files - a directory of files in the CDN multi-parts format
+
+### Multi-Parts Format
+The structure for CDN files in this format is:
+* `./definition.json.gz` - JSON data storing the hash of the files, and the hash of each part
+* `./parts/{idx}` - each part stored as `0`, `1`, etc. Each file is uncompressed and roughly 2MB
+
+
+### File Validation Process
+The workflow for list validation in 3.0 is as follows:
+1) Load the `configs/forced_healing.json` file that contains mirrored and patch files specified by list authors
+2) Download every modlist and archive it for future use, if already downloaded, don't redownload
+3) For each modlist, load it, and start validating the files
+4) For each file that passes, return `Valid`
+5) If the file fails, check the mirrors list for a match, if it matches return `Mirrored`
+6) If the file fails, check the patches list for a match,
+   * If one is found, validate the new file in the patch, if it fails try the next patch
+7) If all patches fail to match, return `Invalid`
+8) Write out reports for all modlists
+
+### List Author Interaction
+List authors now have two controls they can use:
+* `wabbajack-cli.exe force-heal -o <old_file> -i <new-file>` 
+  * Creates a patch for back porting `<new-file>` to `<old-file>`
+  * Uploads the patch
+  * Adds the patch go the `config/forced_healing.json` file
+* `wabbajack-cli.exe mirror-file -f <file>`
+  * Uploads a file as a mirror
+  * Adds the file to the `config/forced_healing.json` file
+  * Note: using this to violate author copyrights is strictly forbidden do not mirror files without seeking prior approval from WJ staff.
