When a candidate's\nstart is misaligned, realign it: free the misaligned run and reallocate\nexactly @size at the next lower min_block_size boundary. This keeps the\nreturned size unchanged with no surplus to trim, and rejects the request\nonly when no aligned candidate fits.\n\nv2: align misaligned candidates down to min_block_size instead of\n    bailing out, for both the RHS and LHS paths (Matthew).","state":0,"publishedAt":"2026-08-15T05:54:31.866+00:00","modifiedAt":"2026-10-16T18:55:12.711+00:00","affected":[{"ecosystem":"Vendor
