List experiment updates

Experiment identifier

Maximum number of items to return (1-100, default 50).

Number of items to skip (default 0).

Filter expression in s-expression syntax.

Comparison: eq(field,value), neq(field,value), gt(field,value), lt(field,value), gte(field,value), lte(field,value), contains(field,substring)

Range/set: between(field,lo,hi), in(field,v1,v2,...)

Logical: and(expr1,expr2,...), or(expr1,expr2,...), not(expr)

Null checks: is_null(field), is_not_null(field)

JSONB access: at(field,key) — e.g. eq(at(metadata,score),42)

Cast functions: float(expr), int(expr), text(expr), timestamp(expr), date(expr)

Example: and(gte(created_at,2026-01-01),eq(status,draft))

Sort expression. Supports multi-column sort (comma-separated, up to 8), JSONB path access, and type casts.

Three accepted surface forms produce the same ordering:

• Canonical — desc(field) / asc(field); also wraps casts and at(...) JSONB path access. Example: asc(date(at(metadata,start_date))).
• Prefix short form — -field (descending), +field or bare field (ascending). GitHub / Stripe / Jira convention. Bare field only; no casts.
• Suffix short form — field:asc / field:desc. Also bare field.

Examples: -created_at, -created_at,+name, created_at:desc, desc(created_at),asc(name), asc(at(metadata,score)).
