/**
 * Wire marker keys shared between @nifrajs/core and the @nifrajs/node adapter.
 *
 * Each entry names a symbol looked up with `Symbol.for(...)`, so the two packages agree ONLY by the
 * string. A rename on one side and not the other is a silent protocol break - no type error, just a
 * symbol that never matches and a body that stops taking the direct-write lane. This module is the
 * single source: core defines its own symbols from these literals, and `scripts/gen-node-outcome.ts`
 * copies the map verbatim into the adapter's generated contract, so @nifrajs/node reads the identical
 * strings without a runtime dependency on core (the same deployment shape the generated outcome type
 * preserves).
 *
 * Keep this module import-free: every core file that owns one of these symbols imports it, so a cycle
 * here would reach most of the response path.
