From PR #26 (review 209, audit). In sword/src/install/http.rs the chunk path treats 416 Range Not Satisfiable as a fatal Http(416). It fails when a part file is longer than the server's file, which happens when a validator-less file (no ETag, no Last-Modified) shrinks, or when the saved total no longer matches. The download then fails on every retry until the part and state files are removed by hand, so the user sees a module that can never be installed.

Fix: on 416, drop the part and state files and restart from 0 once, then fail if it repeats. Add a testserver case: a validator-less file that shrinks below the part.

Trunk: sword/src/install*. Part 2 of #10 will surface install errors in the module manager, so this should land before or with it.
