## Summary Add an opt-in source-development loop that restarts the dashboard and engine when runtime TypeScript or JSON changes. Use `pnpm dev:watch`; `pnpm dev:hmr` now combines Vite UI HMR with the same supervised API/engine restart path. The watcher filters tests, fixtures, generated declarations, build output, and task state. It coalesces bursts with a two-second maximum wait, waits for the child to acknowledge its IPC listener, and rebuilds runtime dist artifacts before a source-triggered respawn. ## Safety model - Close scheduler, triage, heartbeat, mission, routine, self-healing, and merge admission before checking for active work. - Let already-running agents reach a safe boundary; do not mutate durable pause settings. - Enter the existing graceful exit-code-86 shutdown and supervised respawn path. - Retry failed liveness reads and declined restart requests instead of dropping the pending change. - Keep ordinary `pnpm dev` behavior unchanged; inherited watch state does not break nested non-dashboard development commands. A development restart intentionally replaces the dashboard process, so transient dashboard connections and project dev-server children reconnect or restart with it. Agent work is the protected boundary. ## Validation - `pnpm lint` - `pnpm test:gate` (753 tests passed across engine, core, PostgreSQL gate, and CI-shape suites) - Focused CLI watcher/restart/supervision suites: 40 tests passed - Focused engine drain/manager suites: 52 tests passed - `pnpm --filter @runfusion/fusion typecheck` - `pnpm --filter @fusion/engine typecheck` - `pnpm verify:fast` (13 steps passed, including CLI build and real health boot smoke) - Manual unsupported-command probe confirms explicit `--watch` fails clearly outside the dashboard command ## Post-Deploy Monitoring & Validation - Watch for `[fusion:dev] source changed`, `source restart deferred`, `active work drained`, and `restart requested` logs during the first watched development session. - Healthy behavior is one exit-86 respawn per edit batch, no interrupted active agents, refreshed dist artifacts, and a healthy dashboard after respawn. - Investigate repeated restart loops, watcher attachment warnings, declined restart retries, or liveness-read failures. - Immediate mitigation is to use ordinary `pnpm dev` without `--watch`; no production runtime behavior or durable setting needs rollback. - Validation owner: Fusion maintainers during the first source edit after merge. --- [](https://github.com/EveryInc/compound-engineering-plugin) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added `pnpm dev:watch` to automatically restart development runtime processes when source files change. * Development restarts now wait for active work to finish, preventing new work from starting during the transition. * Enhanced `pnpm dev:hmr` with graceful runtime source restarts while keeping the dashboard available. * Rapid source changes are grouped to avoid unnecessary restarts. * **Documentation** * Updated development setup and contribution guides with the new watch workflow. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Fields
| Field | Required | Description |
|---|---|---|
summary |
Yes | One line, user-facing, max 120 chars. Describe what changed for the operator. |
category |
Yes | One of: feature, fix, breaking, security, performance, internal. |

Audience
The summary is the only content that appears in end-user release notes by default. Write for Fusion operators — describe behavior, fixes, and what changed. Avoid internal class names, file paths, and implementation detail.

Validation
Run pnpm check:changesets to validate. The linter runs in the PR-check gate and test:gate. Legacy freeform changesets pass with a warning during the transition period.
