Expand description

Emit const NAME := <literal> for one workload param into source, choosing the literal value via the canonical chain-aware lookup order:

  1. parent_kernel.lookup(name) — if Some, this is the chain-resolved value. A bindings: / set: scope above us may have shadowed the workload-param default; whichever const NAME := <override> is closest in the chain wins via the local-final transit-suppression rule (SRD-13f §“Local-authoritative shadow”). If the lookup is non-scalar (vectors etc.), skip the chain path and fall back.
  2. hashmap_default — the workload-load-time default from params: plus CLI overrides. Used when nothing in the chain has a value for name.

Pre-marks name in emitted so subsequent cascade passes in the caller skip it. Optionally appends to inherited_names for the inherited-output bookkeeping consumers also do.

Why this helper exists: pre-helper, seven distinct synthesizer sites each rolled their own const NAME := <hashmap> emission, reading the HashMap directly without consulting the chain. Any name a scenario-tree set: or bindings: scope shadowed kept the stale HashMap default inside any sub-scope synthesized via one of those sites — breaking the SRD-21 / SRD-18 contract that the kernel chain is the single resolution surface. Routing through this helper closes that hole categorically.
