Absolute Breadth Index: preserve magnitude and evidence

Choose a scenario, step through its causal evidence, and watch raw ABI appear only when the revision is resolved.

Historical Nasdaq counts and Composite levels are provider observations. Net and ABI are author-derived. The historical pair is intentionally incomplete under the production contract.

2026-03-25: advances dominate

Bounded historical lesson
Advances, declines, signed Net Advances, and raw ABI Bars and exact labels compare advances and declines while a separate signed bar shows direction and an ABI bar shows non-negative magnitude. Issue counts Signed Net Raw ABI Advances Declines Net ABI 3,254 1,611 +1,643 1,643
Author-derived lesson arithmetic|3,254 − 1,611| = 1,643
What to notice now

The arithmetic is useful, but it is not a resolved output.

The official row supplies counts, not the stable roster, full partition, availability clock, policy, or revision lineage required by the production evaluator.
