+# Structured Concurrency in Evolu
+
+## Overview
+Evolu uses a custom implementation of structured concurrency to manage async operations, resource lifecycles, and cancellation. This replaces "fire and forget" promises with a strict tree structure where no child outlives its parent.
+
+## Core Concepts
+
+### Task
+A functional effect description (lazy promise) that requires a `Runner` to execute.
+
+```typescript
+type Task<Success, Error = never, Deps = object> = (run: Runner<Deps>) => Promise<Result<Success, Error>>;
+```
+
+### Runner
+The execution context. It provides:
+- Dependency injection (`run.deps`).
+- Abort signaling (cancellation propagation).
+- Resource management (via `AsyncDisposableStack`).
+
+### Platform-Specific Runners
+As of `upstream/common-v8`, runners are platform-aware:
+
+1.  **Web (`packages/web`)**:
+    - Hooks into `globalThis` for `error` and `unhandledrejection`.
+    - Cleans up listeners on dispose.
+
+2.  **Node.js (`packages/nodejs`)**:
+    - Hooks into `process` signals (`SIGINT`, `SIGTERM`, `SIGHUP`).
+    - Provides graceful shutdown capabilities via `run.deps.shutdown`.
+
+## Usage Pattern
+
+### Creating a Runner
+**DO NOT** use generic `createRunner` directly for app entry points. Use the platform-specific library.
+
+```typescript
+// Web
+import { createRunner } from "@evolu/web";
+// Node
+import { createRunner } from "@evolu/nodejs";
+
+const main = async () => {
+   await using run = createRunner();
+   const result = await run(myTask);
+};
+```
+
+### AsyncDisposableStack
+Resources that need cleanup should implement `AsyncDisposable` or be registered with the runner's stack environment.

+# Test Nuances & Known Flakes
+
+## TreeShaking Tests
+**File**: `packages/common/test/TreeShaking.test.ts`
+
+### Issue
+Bundle size measurements can fluctuate slightly (typically < 20 bytes) between different environments (local dev vs CI vs `bun verify`).
+
+### Cause
+Likely differences in compression/minification details or environment-specific overhead in the test runner.
+
+### Mitigation
+- If checks fail on size mismatch, use `bun test -u packages/common/test/TreeShaking.test.ts` to update snapshots locally.
+- Be aware that `verify` might fail purely due to this flake even if logic is correct.
+
+## Bun Verify vs Bun Test
+`bun verify` runs the full monorepo check sequence. Sometimes `bun test` passes in isolation while `verify` fails due to cache/state issues.
+**Fix**: Run `bun run clean` in the failing package before retrying verification.

+# Bun Migration & Cleanup & Default Branch
+
+> **Status**: ✅ Completed
+> **Last Updated**: 2026-02-03
+> **Branch**: `main`
+
+## Summary
+Complete migration from pnpm/ESLint/Prettier to Bun/Biome across the entire monorepo. This replaces the complex cherry-pick strategy with a "Fresh Start" from `upstream/common-v8`.
+Also, set `main` as the default branch on GitHub.
+
+## Tasks
+
+- [x] **Cleanup Legacy Tooling**
+  - [x] Remove `pnpm`-related files (`pnpm-lock.yaml`, `pnpm-workspace.yaml`, `.npmrc` if any)
+  - [x] Remove `eslint`-related files (`.eslintrc`, `eslint.config.mjs`, `.eslintignore`, etc.)
+  - [x] Remove `prettier`-related files (`.prettierrc`, `.prettierignore`, `prettier.config.mjs`)
+  - [x] Scan and update `package.json` in all packages to remove `eslint`/`prettier` scripts and deps
+  - [x] Run `bun run clean` & `bun install` to ensure clean state
+- [x] **Set Default Branch**
+  - [x] Set `main` as default branch on `origin` (SQLoot/evolu-plan-b)
+- [x] **Verification**
+  - [x] Verify build passes without legacy tools
+  - [x] Verify `lint` command runs Biome only

+# Merge & Integrate Upstream Commits
+
+> **Status**: ✅ Completed
+> **Last Updated**: 2026-02-03
+> **Branch**: `sync/merge-upstream-03-02-26`
+
+## Summary
+Integration of 14 commits from `upstream/common-v8` bringing significant changes to the Task runner architecture and tooling.
+
+## Key Changes
+- **Structured Concurrency**:
+  - `TaskDisposableStack` -> `AsyncDisposableStack`.
+  - `runMain` -> `createRunner` (platform-specific implementations).
+  - Web: Uses `globalThis` event listeners for error handling.
+  - Node.js: Uses `process` signals (SIGINT, SIGTERM) for graceful shutdown.
+- **Relay**: `createNodeJsRelay` -> `startRelay`.
+- **Tooling**: Full removal of `pnpm` artifacts, reliance on Bun & Biome.
+
+## Verification
+- `bun verify` passes (with caveats, see below).
+- Manual confirmation of `createRunner` types export.
+
+## Known Issues
+- **TreeShaking Test**: `packages/common/test/TreeShaking.test.ts` shows minor bundle size fluctuations (~9 bytes) between local `bun test` and `bun verify` / CI. This is a known environmental flake.
