name: op-filter-true
description: Keep records where Field is logically true. Strict packed_bool by default; opt into JS truthiness.

Use when

Keeps only the rows where a yes/no field is yes, such as active accounts or completed surveys.

Questions it answers:

What do only the completed interviews say?
What are the figures for active subscribers?

Use something else:

FILTER_FALSE when you want the rows where the field is no.
FILTER_EXPRESSION when the condition involves more than one field.

Params

Name	Type	Default	Description
`Values`	`[]string`	empty (strict)	Omit, or `["strict"]`, requires `packed_bool` and matches raw `1`. `["truthy"]` enables JavaScript-style coercion across any field type. Other values → `PROCESSING_CONFIG`.

Inputs

Param	Accepted field types
`Field`	strict mode: `packed_bool` only. Truthy mode: any cohort field type.

Output

Row-level predicate. Pass when value is true / truthy. No emitted column.

Components

Floor only — no operator-specific keys. Universal {n_in, n_out, n_null_input} per response-components contract. Mergeable across chunks.

Gotchas

Strict mode on non-packed_bool → PROCESSING_CONFIG with the suggested Values=["truthy"] fix.
Truthy mode coerces: 0, NaN, "", null → falsy; everything else → truthy. Null rows DROP in both directions.
decimal128 truthiness uses Sign() != 0.
