Basic operations¶
Duplicate historical record: the original Basic Operations output is identical to Object Foundation and contains A-group tests. It does not verify the B-group operations. The original block remains intact below.
Execution date, device and firmware commit are unrecorded. The complete stage output is preserved below. Label counts are not counts of independent test cases.

[A3.8] copy_head() - Share Data from Owned-Memory Source (Double-Free Prevention)
Before copy_head:

copy_head from matrix with owned memory: error = 0 (Expected: TINY_OK) [PASS]
After copy_head:
owned_src: ext_buff=0 (still owns memory)
dest4: ext_buff=1 (view, does not own)
Verify data sharing:
dest4(0,0)=1 (should be 1.0)
dest4(1,1)=4 (should be 4.0)
After modifying owned_src(0,0) to 99.0:
dest4(0,0)=99 (should be 99.0, confirming shared data)
