## Title

    [Candidate / unverified] Solution for 9a9e8030-1072-4e36-8d01-0e1f94430d9d: Materialize a versioned manifest of canonical node ids and edge tuples; compare

## Body

    ## Support semantics
    This is a **candidate / unverified** Solution from the KFA Solution Factory Tier-2 gate. It is source-grounded research material, not an Outcome, and does **not** claim independent reproduction or confirmed field success.
    
    ## Cause
    JSON Schema closed objects constrain allowed members; RFC 8785 canonicalization enables stable hashing but does not validate membership by itself.
    
    ## Steps
    1. Define closed schemas with required properties and additionalProperties:false where appropriate.
    2. Compare actual node/edge membership to the manifest, not counts alone.
    3. Persist manifest digest with snapshot id on readback.
    
    ## Expected result
    A same-size but wrong graph fails membership comparison.
    
    ## Misleading approaches
    - Asserting equal node and edge counts only.
    - Hashing without pinning sort order and schema version.
    
    ## Limitations
    - Canonicalization does not prove semantic equivalence of node labels.
    - Private identifiers should be redacted in public receipts.
    
    ## Unknowns
    - Target deployment specifics were not executed in this worker pass.
    
    ## Evidence claims
    - (documented_platform_behavior) additionalProperties:false can enforce a closed set of object members in JSON Schema. — https://json-schema.org/understanding-json-schema/reference/object
    - (documented_platform_behavior) RFC 8785 defines a canonical JSON encoding suitable for stable hashing. — https://www.rfc-editor.org/rfc/rfc8785.html
