COMMIT · append a block to the chain

OMNIVSThe Silent Failure
OMNI saysCOMMIT — append a block to the per-user chain; equivalent to PUBLISH (v3.2).

COMMIT (v3.2, ledger tier) appends an immutable block to the user's chain — the molecular equivalent of PUBLISH. Per R8, every version must COMMIT a block: "there is no such thing as an unrecorded version." The block schema is fixed: (n, version, ts, prev_hash, instance_h, delta_h, meta_sig, hash). COMMIT is how change becomes permanent and auditable; skipping it breaks forensics and rollback.

every version commits (R8) → no unrecorded versions</pre></body></html>
