# Recorded extraction failures

The original 28 October snapshot reported 551 unresolved error records across these inputs:

|Input|Error records|
|-|-|
|Largest Font Collection.zip|18|
|Worlds Largest Font Collection 600000.zip|533|

|Recorded reason|Records|
|-|-|
|Decoder rejected an unsafe, encrypted or invalid member|12|
|Legacy archive reader could not produce a valid inventory|9|
|Unsupported StuffIt decoding path|3|
|Stored member identity/CRC record disagreed during retry|8|
|Multipart RAR needed its complete validated volume set|519|

These are error records, not counts of distinct lost fonts or irrecoverable archives. Repeated attempts and individual multipart volumes can produce several records for the same set. Some records predate partial recovery; their presence does not mean every descendant failed.

Affected examples include wrapped multipart RAR sets in `Worlds Largest Font Collection 600000.zip`, the Arnhem and Scriptana packages, and older Atomicmedia Mac archive chains. No missing output was fabricated. Successfully retained fonts are included independently of unresolved siblings.

Unfinished recovery is listed under [pending work](pending.md). This release does not establish that the remaining failures are permanently irrecoverable.

The Drive import completed its outer ZIP and nested RAR traversal without recorded extraction errors. The historical records above remain unresolved.

The Pixeldrain RAR traversal also completed without recorded extraction errors. No historical recovery statuses were changed.
