# ADR-006: EditorState owns concrete workspace config (https://jackin.tailrocks.com/reference/adrs/adr-006-editor-state-workspace-config/)



**Status**: Accepted\
**Current state**: `EditorState` stores concrete `jackin_config::WorkspaceConfig` values for `original`
and `pending`; the remaining editor type parameters stay generic for modal, save-flow, auth, and pending
worker test seams.\
**Date**: 2026-07-04\
**Deciders**: Operator + agent

## Context [#context]

Plan 022 measured the cost of `jackin-console`'s generic host-console core. The editor state had eleven
type parameters, but production always bound the first one to `jackin_config::WorkspaceConfig` through
`crate::tui::state::EditorState<'a>`. That parameter leaked into impl blocks and type aliases without
preserving a real production substitution.

The other editor parameters are different. Unit tests use lightweight modal, cache, auth-target, and
pending-worker placeholders to characterize model and view behavior without constructing the whole console
surface. Removing those parameters would trade useful test seams for less syntax and needs separate
measurement.

## Decision [#decision]

`EditorState` owns the workspace-config type concretely:

* `original` and `pending` are `jackin_config::WorkspaceConfig`.
* `WorkspaceConfig` is no longer an `EditorState` generic parameter.
* `WorkspaceEditorState` and the root `crate::tui::state::EditorState<'a>` aliases forward one fewer type
  argument.
* Modal, save-flow, auth-target, env-value, and pending-worker slots remain generic.

This is a narrow collapse, not a rejection of the functional-core shape.

## Consequences [#consequences]

* Direct `EditorState<...>` spell-outs shrink by one argument.
* The editor model and state impl blocks no longer carry an unconstrained concrete type as ceremony.
* Existing lightweight tests still instantiate compact editor states with `()` or small test modal types.
* Further generic collapse must be measured separately before Plan 023 decomposes `jackin-console` by
  responsibility.
