This disclosure relates to a symbolic containment firewall that evaluates and governs natural language transactions before they modify state in downstream computer systems. Incoming text is associated with a configurable domain profile and normalized, and heuristic features such as entropy, anchor coverage, omissions, and contradictions are computed. A model adapter obtains a model assisted structural stability score, and a symbolic containment engine combines the heuristic features and model score into a containment stability score and containment stability label. A decision stage selects a pass, block, or escalate action and may generate refactored text that satisfies domain profile requirements. For each transaction, the system constructs a canonical audit object that captures the input, context, analysis, and decision, computes a cryptographic seal over a deterministic representation of the audit object, and writes the sealed audit object to write once read many storage that gates downstream execution and enables later verification of containment decisions.

Write-once-read-many in cloud for file systems backed up to object storage (e.g., using a computerized tool), is enabled. For example, a system can comprise at least one processor, and at least one memory that stores executable instructions that, when executed by the at least one processor, facilitate performance of operations. The operations can comprise identifying changes to data in a file of a file system relative to a first version of an object chunk representative of the data in an object store, wherein the data is determined to comprise a defined data retention policy, copying changed data, of the data, from the file system to a second version of the object chunk, and copying unchanged data, of the data, from the first version of the object chunk to the second version of the object chunk.
