Coverage proof before the upsell

The kit is sold on audited delivery and visible limits. Behind the scenes, quarantined alternate-source checks help us distinguish real source-empty ranges from gaps that deserve deeper repair work.

Alternate-source checks are internal validation inputs. Paid artifacts still ship from approved release packages with coverage reports.

Why this is not just another data download

Free data exists. The product is the cleaned, packaged, inspected workflow layer that helps a buyer decide what data is safe to use.

Stop rebuilding commodity plumbing

The bundle packages the download, normalization, resampling, and QA layer so buyers can spend time on research instead of file repair.

Know where not to test

Coverage visibility helps buyers avoid drawing strategy conclusions from ranges that still need source-backed repair.

Build repeatable workflows

Parquet delivery makes it practical to query the same release from pandas, DuckDB, R, or a local app without API quotas.

Proof assets

The offer gets stronger as the proof improves. These are the assets that make the bundle easier to trust than a folder of raw exports.

  • -Pair-level release coverage report.
  • -Known-gap visibility rather than hidden continuity claims.
  • -Duplicate timestamp, null, schema, and invalid-OHLC checks.
  • -Parquet files that load directly into local analytics workflows.
  • -Completed source-backed Major-8 backfill plan with no remaining planned intervals.

Major-8 kit questions

Does the Major-8 kit include all gaps repaired?+
No universal gap-free claim is made. The current release is audited and coverage-reported, with known source-observed gaps disclosed separately from structural defects.
Why buy this if free sources exist?+
Free sources still leave buyers with downloading, merging, timezone handling, format conversion, deduplication, and coverage proof. This kit sells that workflow layer.
What happens after new backfill data is processed?+
The release is rebuilt, quality-audited, coverage-reported, and uploaded as the next R2 fulfillment artifact after checks pass.
