The new helper centralizes the invalidation plan, emits per-section `targets`, and drops the previous `forcedGlobal` behavior that caused every global change to flush MCP/LSP/Plugin state. +- `Bus.subscribe` now calls `apply` directly, so we can unit-test the invalidation matrix without going through the HTTP stack. +- The new regression test `theme-only global updates avoid unrelated invalidations` in `packages/opencode/test/config/hot-reload.test.ts` invokes `ConfigInvalidation.apply` with a synthetic diff and asserts that only the `theme` state is touched. + +### Performance & Log Evidence +- Prior to the fix, a theme-only change produced four subsystem invalidations (`provider`, `mcp`, `lsp`, `plugin`) plus tool-registry churn, as shown in the 2025-11-12 logs in this document. +- After the refactor, the same scenario logs a single target: + +```text +INFO service=config.invalidation scope=global directory=/tmp/theme-only-oMAT6r config.invalidate.stateRefreshed +INFO service=config.invalidation scope=global directory=/tmp/theme-only-oMAT6r sections=["theme"] targets=["theme"] config.invalidate.start +INFO service=config.invalidation scope=global directory=/tmp/theme-only-oMAT6r sections=["theme"] targets=["theme"] config.invalidate.complete +``` + +- That reduces invalidation fan-out from 4+ subsystems down to one, eliminating roughly 75% of the work for theme edits. The improvement is enforced by the updated test suite (`bun test packages/opencode/test/config/write.test.ts packages/opencode/test/config/hot-reload.test.ts`). + +## What Was Implemented + +### Phase 0: State System Enhancements + +**Files Modified:** +- `packages/opencode/src/project/state.ts` -

The new helper centralizes the invalidation plan, emits per-section `targets`, and drops the previous `forcedGlobal` behavior that caused every global change to flush MCP/LSP/Plugin state. -- `Bus.subscribe` now calls `apply` directly, so we can unit-test the invalidation matrix without going through the HTTP stack. -- The new regression test `theme-only global updates avoid unrelated invalidations` in `packages/opencode/test/config/hot-reload.test.ts` invokes `ConfigInvalidation.apply` with a synthetic diff and asserts that only the `theme` state is touched. - -### Performance & Log Evidence - -- Prior to the fix, a theme-only change produced four subsystem invalidations (`provider`, `mcp`, `lsp`, `plugin`) plus tool-registry churn, as shown in the 2025-11-12 logs in this document. -- After the refactor, the same scenario logs a single target: - -```text -INFO service=config.invalidation scope=global directory=/tmp/theme-only-oMAT6r config.invalidate.stateRefreshed -INFO service=config.invalidation scope=global directory=/tmp/theme-only-oMAT6r sections=["theme"] targets=["theme"] config.invalidate.start -INFO service=config.invalidation scope=global directory=/tmp/theme-only-oMAT6r sections=["theme"] targets=["theme"] config.invalidate.complete -``` - -- That reduces invalidation fan-out from 4+ subsystems down to one, eliminating roughly 75% of the work for theme edits.
