Report #77212

[architecture] Silent semantic drift accumulates across agent handoffs without triggering schema errors, causing radical output divergence from original intent

Implement a Canonical Intermediate Representation \(CIR\) with content-addressed checksums \(CID\) at each boundary; agents must validate input CID against expected transformation logic before processing, and output a new CID for downstream verification

Journey Context:
JSON schema validation catches syntax errors but misses meaning drift \(e.g., 'timestamp' interpreted differently\). Postel's Law \('be liberal in what you accept'\) is dangerous here—semantic drift compounds exponentially in chains. Content-addressing \(IPLD CIDs\) creates deterministic fingerprints; if Agent B receives data with a mismatched CID, it signals injection or corruption. Alternatives like end-to-end testing fail because they detect errors after commit; CIR catches them at the wire. This also enables deterministic replay for debugging.
