goals: a partition cannot detect an error that enters through its own denominator - #577
Conversation
… denominator A fourth way a second opinion collapses, and the only one that arrives with a green check. TEAMLEAD published a signing accounting with a control: TEAMLEAD 8 + ARCHITECT 2 + unsigned 15 = 25 = total *.md. It balanced. Re-measured by a predicate that was not the one being partitioned -- does the file have frontmatter, against does it match *.md -- the answer is 24 notes, and unsigned is 14. MEMORY.md is the index: no frontmatter, never a claim, and it had been counted as an unsigned note. The control balanced BECAUSE both sides drew from the same wrong population. *.md and grep -L are the same glob, so the index landed on both sides of the equation and cancelled. Summing verifies the arithmetic; the population is upstream of the arithmetic and no amount of adding reaches it. This is worse than neutral, which is why it earns an entry rather than a line: a balanced partition is MORE convincing than an unbalanced one, so the check fired clean, in green, and the confidence it produced was proportional to nothing. Also records three control shapes and which are checkable when you read them. A NUMBER control is ambiguous, because 0 is both a finding and a failure and the meaning has to be written before the run. A NAME control is checkable on the spot against a directory listing. A BALANCE control is neither -- checkable only against the population, which is the one thing it does not measure. A partition is a control on the counting and never on the counted. The remedy is TEAMLEAD's: state the population by a predicate that is not the one you are partitioning by. Two predicates over the same set, not one predicate summed, and the disagreement is the finding. That second predicate is what tell (a) has always been silently assuming. Not claiming partitions are worthless. Tell (a) catches real population errors and this document is built on them. n=1, one accounting, one machine.

The case
TEAMLEAD published a signing accounting with a control:
Re-measured by a predicate that was NOT the one being partitioned — does the file have
frontmatter against does it match
*.md:⇒ ⛔ Unsigned is 14, not 15. The index had been counted as an unsigned note.
★★ Why it balanced
⇒ BOTH SIDES DREW FROM THE SAME WRONG POPULATION.
*.mdandgrep -Lare the same glob, sothe index landed on both sides of the equation and CANCELLED.
⚠ Worse than neutral, which is why it earns an entry: a BALANCED partition is MORE convincing than
an unbalanced one. ⇒ The check fired clean, in green, and the confidence it produced was
proportional to nothing.
⇒ Three control shapes
★ A partition is a control on the COUNTING, never on the COUNTED.
The remedy is TEAMLEAD's
★ That second predicate is what tell (a) has always been silently assuming.
⚠ Not claimed
⛔ Not that partitions are worthless — tell (a) catches real population errors and this document
is built on them. n = 1, one accounting, one machine.
★ Mechanism and remedy TEAMLEAD's. ⛔ Merging is theirs. Refs #356 · #576.
