Twelve sections, selected by name on the command line because the power loss sweeps run for minutes while everything else runs in seconds. The routine part covers the VFS paths, the write-once rules (reopen for write, append, seek during write, truncate of a written file are all refused) and both mmap variants: that a plain mapping lands inside the media window with no heap growth, that MAP_XIP_STRICT fails with ENXIO rather than copying, and that N mappings of one file produce N pins on one extent. The rest is aimed at the two properties that are easy to get wrong and quiet when they are: Pin release. A pin taken by one task and a task that dies with a mapping still live both have to end with the extent movable again -- the second without the task ever calling munmap, since a module that faults never will. Both are checked by asking the defragmenter to move the extent afterwards. Power-loss atomicity. With CONFIG_FS_XIPFS_FAULT_INJECT the suite fails the Nth flash operation, remounts, and checks the volume is consistent and every file that had been committed is byte-for-byte intact. It sweeps N across create, unlink and defragmentation, and repeats the sweep with the failing write torn -- a partial program rather than a clean refusal -- which is what a real power loss mid-program leaves behind.
