Control

Workflow	Type	Description
control.collection.distinct	Atomic	Drop duplicate elements (optionally by a field), preserving order
control.collection.filter	Atomic	Keep the list elements matching one comparison predicate
control.collection.flatten	Atomic	Flatten nested lists up to a given depth (-1 = fully flat)
control.collection.group_by	Atomic	Bucket list elements into an object keyed by a field path
control.collection.map	Atomic	Apply one unary transform (cast/case/abs/length…) to every list element
control.collection.match	Atomic	Match two record lists by exact or decimal-tolerance rules without guessing collisions
control.collection.pluck	Atomic	Extract one field (dotted path) from every element into a flat list
control.collection.reduce	Atomic	Aggregate a list with count/any/all/sum/min/max into one value
control.collection.slice	Atomic	Take a bounded window of a list (offset/limit; negative offset = from end)
control.collection.sort	Atomic	Sort a list (optionally by a field path), ascending or descending
control.flow.guard	Atomic	Assert a condition; pass through if it holds, else fail the branch with a reason
control.flow.wait	Linear	Pause for a bounded delay (seconds or until an epoch) before continuing
control.http.request	Atomic	Make a generic HTTP/REST request so integrations without a first-class workflow are reachable
control.math.compute	Atomic	Evaluate one arithmetic op (add/sub/mul/div/mod/pow/min/max/abs/neg/round)
control.policy.evaluate_matrix	Atomic	Evaluate a list of items against reusable policy rules and summarize compliance
control.poll.until	Linear	Poll a read-only probe workflow until a predicate on its output holds (or stop/deadline)
control.predicate.combine	Atomic	Combine a list of booleans with all/any/none into one result
control.predicate.compare	Atomic	Compare two values with one operator, emitting a boolean result
control.switch.select	Atomic	Map a value to a branch label via a cases table (with optional default)
control.text.extract_matches	Atomic	Extract regex matches from text into deterministic JSON row objects
control.text.join	Atomic	Join a list into a string with a separator (default empty)
control.text.replace	Atomic	Replace substrings in a string (literal or regex)
control.text.split	Atomic	Split a string into a list by a separator (default: whitespace)
control.time.now	Atomic	Emit the current UTC time (iso8601/date/epoch) as a value for downstream steps
control.value.build	Atomic	Build one object from a fields dict, with optional defaults and null-dropping
control.value.cast	Atomic	Coerce a value to a declared type (str/int/float/bool/json/list)
control.value.coalesce	Atomic	Return the first non-null value from an ordered candidate list
control.value.format	Atomic	Interpolate {0}..{7} placeholders in a template from positional arg0..arg7 — the composition-friendly form of control.value.template (each argN is a top-level input so a composition can bind a ref to it without nesting inside a values dict).
control.value.get	Atomic	Extract a nested value from an object/list by a dotted/indexed path
control.value.merge	Atomic	Merge two objects (overlay wins); deep (recursive) or shallow
control.value.set	Atomic	Set one key on an object to a value, composing objects across steps
control.value.template	Atomic	Interpolate a string template ({name} placeholders) from a values dict
control.version.lag_summary	Atomic	Aggregate version-lag evidence rows into a deterministic summary
control.version.select_latest	Atomic	Select the latest comparable version and compute current-version lag evidence
