FE-012C Repeatability Observations

Repeatability outputs are present and a reproducible dataset comparison pipeline is available through npm run compare.

Use the generated reports in comparison/generated/ as the primary analysis artifacts.

Current generated comparison summary:

• Parsed observations: 90 of 90 expected across both datasets.
• Dataset B files requiring quote normalization before parsing: 15.
• Stable packet/model pairs: 1 of 45.
• Elaboration drift pairs: 8 of 45.
• Structural drift pairs: 36 of 45.
• Backbone-stable pairs: 9 of 45.
• Recognition drift pairs: 41 of 45.

Immediate interpretation:

• The repeatability dataset is usable as collected.
• Storage-format noise exists but did not block parsing.
• Drift is common enough that repeatability should not be described as established.
• Transition and sequence changes dominate the observed differences.

Interpretation constraints:

• Stable agreement is measurement evidence, not theory validation.
• Drift may reflect packet ambiguity, vocabulary pressure, or provider-specific elaboration behavior.
• Repeatability conclusions should be grounded in the generated comparison outputs rather than ad hoc inspection.

Capability Role Review Initiated

Observation:

"The literal and first semantic comparators may be operating below the correct abstraction level. Manual review will determine whether capability-role comparison better represents procedural reasoning agreement."
