Could you build this?

No Writing a crash-safe embedded key-value store in C demands deep systems programming knowledge regarding memory management, ACID transaction guarantees, write-ahead logging (WAL), and file system sync semantics.

What it would actually take: Requires low-level C programming implementing data structures like LSM-trees or B+ trees, write-ahead logging (WAL), lock-free concurrency, and explicit page cache flushing via fsync/fdatasync. The core difficulty lies in formal verification of crash safety across power failures and sudden process termination, buffer management, and preventing race conditions or memory leaks without high-level runtime safety nets.
