Cryptext x64 tests
==================

Current dev30 password/vault synchronization regression:
- README_0.11y_dev30.txt

Current dev30 fix1 NC-skin geometry check:
- README_0.11y_dev30_fix1.txt

Current deterministic v1 fixture:
- Cryptext-v1-test-vector.txt
- Cryptext-v1-test-vector.bin
- Cryptext-v1-test-plaintext.txt

Before the real v1 writer is considered complete, add deterministic vectors for:

1. empty file
2. 1 byte
3. chunk_size - 1
4. exactly chunk_size
5. chunk_size + 1
6. multiple chunks
7. Unicode filename / path
8. wrong password
9. corrupted header
10. corrupted ciphertext byte
11. corrupted GCM tag
12. truncated final record
13. unexpected trailing bytes
14. disk-full / interrupted .temp simulations
15. legacy Cryptext 3.4: empty, 1 byte, 16 KiB, 16 KiB+1, larger binary

Each published vector should include password encoding, salt, nonce prefix, KDF
params, expected plaintext SHA-256 and complete expected encrypted bytes or an
exact file hash.

0.3h diagnostic: see README_0.3h.txt for the fixed SecureInput mapping test.
0.3i UI regression: see README_0.3i.txt for ampersand-label and caret checks.
0.4 CNG core: see README_0.4.txt.
0.4a format freeze: see README_0.4a.txt.
0.8 symmetric keep-original + process-session password: see README_0.8.txt.
0.8a multi-selection + remembered-password bullet display: see README_0.8a.txt.
