Effect Harness

Effect Harness publishes a Prelude Harness Module for Effect v4 beta targets.

import effectHarnessEslintConfig from '@sayoriqwq/effect-harness/eslint'
import { harnessModule } from '@sayoriqwq/effect-harness/prelude'

The ESLint export contributes only two composable boundaries: application code must not import delivered repos/effect/** or repos/tsgo/** reference trees. tsgo is the sole authority for Effect and TypeScript semantics; Target owners choose all other ESLint rules in their own flat config.

harnessModule plans a complete Integration-scoped managed knowledge tree, reference-only pinned source diagnostics, and a bounded Control Root routing block. Planning is read-only; Prelude owns convergence of those stable Harness-owned assets.

Integration feedback/** is target-owned and never planned as an Output. Pinned Effect and tsgo sources are delivered offline from canonical archive files in the Artifact with immutable provenance; they are agent references, never application dependencies. The delivered Target Adaptation skill reads immutable managed Baseline and canonical policy data, observes repository-specific topology, obtains authorization before changing Target-owned package, lockfile, TypeScript, activation, lint, editor, or verification state, proves actual Effect-tsgo behavior, then hands ongoing ownership back to that Target.

The reference publication authority chain is Prelude Contract's normative archive protocol → Partita production → Effect Harness composition → Prelude validation and materialization.
