Seam Edge Cast Copy Checker

Organize actual noninvasive seam/porosity evidence for specialist review, not definitive cast-copy identification or destructive testing instructions. Independently established columns: continuous edge seam independently observed, casting porosity independently observed. Unknown observations and overlapping candidates retained; not automatic semantic parsing, proof of identity, fraud, authenticity, compliance or coverage.

Description

Casting-copy review can use separately observed manufacturing features.

Casting-copy review can use separately observed manufacturing features.^[1]

This tool compares a two-feature record with a fixed review candidate while retaining unknown observations.

When to use Seam Edge Cast Copy Checker

Use this tool to calculate or review the supplied observations under the stated rules. Establish the coin issue, source edition, measurement basis and reference date where applicable.

How to use Seam Edge Cast Copy Checker and understand its results

Establish the coin issue, source edition, measurement basis and reference date where applicable.
Enter observedFeatureFlags, featureKnownFlags, using the field meanings and rules below, then run the tool.
Read result. Inspect nested result fields where present, and review unknown records separately from known matches.
Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.

Input field	Meaning	Value type	Requirement
observedFeatureFlags	Observed feature flags	list of number	Required
featureKnownFlags	Feature known flags; binary 1 means the matched observation is known, 0 means unknown	list of number	Required

Supply exactly two binary observed features and binary known flags in the order specified in the feature table. The cast-copy-review-candidate requires both features present. Known mismatches exclude it; unknowns leave it compatible but not fully witnessed.

Feature columns, in order: continuous edge seam independently observed, casting porosity independently observed.

compatible=each known required feature matches; witnessed=all required features known and matching

Use the matching field units and the exact boundary, ordering and reference rules above.

Output field	Meaning	Value type
result	Calculated observation or qualified reference	object
result.compatibleClasses	compatible Classes	list
result.witnessedClasses	witnessed Classes	list
result.unknownFeatureIndices	unknown Feature Indices; zero-based positions in the relevant supplied record or adjacent-pair list; unresolved records kept separate from known results	list

Limitations and assumptions

Coin identification, reference applicability and measurement uncertainty require separate evidence. A returned explanation or arithmetic agreement does not establish authenticity, a certified grade or a current market value.

Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above. Extremely large composite outputs are rejected.

Alternative or Complementary methods

For a related step, use Magnet Response Precious Checker: Magnetic attraction should be compared with the expected response of the identified alloy and issue. For a complementary comparison, use Counterfeit Density Flag Checker: Bulk density is mass divided by volume and can be compared with an issue-specific reference interval.
