Test Case: FLAT_PLAIN Small File

Test ID: TC028-flat-plain-small

Objective

Verify a sub-block regular file explicitly encoded as uncompressed FLAT_PLAIN reads source-exactly.

Fixture

Use images/flat.erofs and source/flat/small.txt. Structured evidence asserts layout 0 and records NID and size.

Procedure

stat -f 'size=%z blocks=%b mode=%p' "$mnt/small.txt"
cmp /tmp/repo22-g1/source/flat/small.txt "$mnt/small.txt"
sha256 /tmp/repo22-g1/source/flat/small.txt "$mnt/small.txt"

Expected Results

• Evidence proves FLAT_PLAIN; size and data match the source.
• The read, hash, mount, and cleanup all succeed.
