Problem strength
Severity and recurrence of the unresolved failure.
METHODOLOGY / VERSIONED AND REPLAYABLE
Interpretation is not measurement.
AI structures permitted language. Deterministic code calculates the Core Market Signal, subindices, Confidence, and movement.
The canonical object
SXGNYL measures Problem Markets: a defined actor attempting a job under a recurring failure mode. Posts, links, trends, and generated ideas are evidence inputs—not markets.
Seven measured dimensions
Commercial evidence
Observed willingness to pay, spend, and transactions.
Unresolved gap
How incompletely existing solutions address the job.
Benefit capture
The economic value a better outcome may retain.
Persistence
Whether the signal survives time decay.
Supply pressure
Solution and competitor pressure, measured separately.
Momentum
Strengthening or cooling evidence over comparable periods.
Confidence is separate
Confidence grades reflect evidence quality, diversity, independence, coverage, specificity, and review quality. A high score does not manufacture high confidence.
Publication boundary
Public pages use delayed certified or explicitly restated closes only. Current provisional intelligence remains a Builder surface. Methodology-version changes are shown as breaks, never silently spliced into comparable movement.
