Goal:
Stop ad-hoc mutable state drift and make edits deterministic.

Scope:

  • Central state store for model, selection, viewport, UI mode, diagnostics.
  • Action/reducer pipeline for all mutations (drag, edit pin, net operations, symbol edits).
  • Add undo/redo as transaction log with typed actions.
  • Persist view/ui preferences safely.

Acceptance:

  • No direct object mutation from UI components.
  • Undo/redo stability under stress (drag-edit-net sequence).
  • Deterministic replay of action log reproduces same model + viewport.

Sprint 1 progress landed in d029e48.

Implemented:

  • Deterministic centralized store foundation at frontend-react/src/state/store.js.
  • Core actions scaffold: setModel, setCompileResult, setSelection, moveComponent, applyJsonText.
  • Undo/redo transaction scaffolding.
  • Determinism and history tests in tests/state-store.test.js.

Validation:

  • npm test passes (includes new store tests).

Status:

  • Partial completion; React UI integration and full action coverage still pending.

Sprint 2 progress in 5a4e116.

Delivered:

  • Added lifecycle slice (isCompiling, lastError, lastAction) and actions (beginCompile, completeCompile, failCompile).
  • Added React subscription hooks (useSchemetaSelector, useSchemetaActions) using useSyncExternalStore.
  • Extended determinism tests for lifecycle behavior and history non-interference.

Validation:

  • npm test passed (includes updated tests/state-store.test.js).

Status:

  • In progress: additional action coverage and broader parity transactions still pending.

Completed by deterministic store/action pipeline integration in Sprint 2/3 (5a4e116, dc9c277). Undo/redo and mutation paths now run through centralized React store actions.
