WP Context

The pipeline's module runner. Holds an ordered list of modules (wildcards, fixed values, combines, derivations, constraints) plus optional bundles that group related modules. Each queue, the engine executes every enabled module in order, building up a context of $variable bindings that downstream nodes consume.

Inputs

upstream (optional) — chain another WP Context to inherit its bindings. Same-name bindings in this node override the upstream.
seed — drives every random pick this run (wildcards, weighted lookups). control_after_generate rotates per queue. Per-row seed locks override per-instance.
modules (widget) — the ordered module list. Picked from the library or created inline.

Output

context — PIPELINE_CONTEXT payload carrying all bindings + run trace + warnings. Feed into WP Prompt Assembler, WP Prompt Cleaner, WP Debug, or chain another Context.

Module kinds

Kind	What it does
wildcard	Picks one option from a weighted list. Roll changes each queue. Supports sub-categories, nested `@{uuid}` refs, null slots.
fixed_values	Assigns explicit `name = value` bindings — no randomness. Quick way to define static vars.
combine	Template-fills `$vars` into a string and writes the result to a new binding. E.g. `$mood $subject` → `subject_phrase = "sleepy cat"`.
derivation	IF/ELIF/ELSE conditional rules over the runtime context. E.g. if `$mood == sleepy` then `$lighting = soft`.
constraint	Re-weights a target wildcard's options based on a source wildcard's pick. E.g. if `$hair == bald` then exclude `$style == braided`. First-instance: fires on the first matching target downstream, then consumed.

Bundles group modules that belong together (e.g. "final framing": all the wildcards + the combine that builds the final prompt). They're reusable across workflows.

How to use

Click + Add module to insert a row. Pick from the library, or create a Fixed Values entry inline.
Order matters — modules run top-to-bottom. A combine that reads $mood must come after the wildcard that picks $mood.
Wire the context output into a WP Prompt Assembler / WP Prompt Cleaner / WP Debug.

Drag a row by its handle to reorder. Drag onto another Context node to move it. Toggle the checkbox to disable a row without deleting it.

Per-row indicators

MODIFIED badge — the row diverges from its library entry (instance overrides applied).
MISSING VAR badge — a combine/derivation references a $var no upstream module provides.
Conflict dots — blue = overriding an upstream binding (info), amber = sibling collision in this Context (warning).
Bundle frame — colored border grouping related modules. Click the bundle header to collapse / toggle the whole group.

Tips

Variables prefixed __ are engine-internal and hidden from the assembler.
Right-click a row for Edit / Duplicate / Save-to-library / Open-in-SPA.
Run once with WP Debug downstream to see exactly what each module produced.
