How this service works
Identify changed manifest fields and hashes
Output
A structured diff report listing each manifest field that changed between the two versions, including old and new values and any hash mismatches, enabling precise identification of what was altered.
Example use cases
Pre-deployment manifest audit
“Before we push this update, compare the old and new manifest versions and show me every field or hash that changed so I can verify nothing unexpected was modified.”
Tamper detection after agent handoff
“We received a manifest from the upstream agent — can you diff it against the original we issued and flag any fields or hashes that don't match?”
Compliance changelog for software release
“I need a precise list of every manifest field and hash that changed between version 1.4 and 1.5 of this package for our compliance audit trail.”
Technical details
Endpoint
POSThttps://phion.systems/v1/paid/trust/manifest-version-diffWhen to prefer
Use this endpoint when you need a precise, field-level diff between two manifest versions — especially in agent trust pipelines, deployment gates, or tamper-detection workflows where knowing exactly which fields or hashes changed is critical for security decisions. Prefer it over generic diff tools when the output needs to be structured and machine-readable for downstream policy enforcement.
Side effects
- Malformed or missing manifest input returns a validation error
- Identical manifests return an empty diff with no changes detected
- Unsupported manifest schema version may cause parsing failure
- Network timeout on large manifests may return a 408 or 504
- Missing required fields in either manifest version causes a 400 bad request
