## What this PR does Closes three lifecycle gaps in the Mission → Milestone → Slice → **Feature** model, where a feature links to exactly one delivery task (single-valued `feature.taskId`, one-feature-one-task): 1. **Reverse-lineage done-credit** — a terminal, non-failed task carrying a feature's reverse `missionLineage` (featureId/sliceId/missionId) now credits the feature as satisfying its acceptance criteria, independent of where the forward `feature.taskId` points (e.g. a newer follow-up task). Credit is only applied when **none** of the feature's lineage candidates is live, so a live follow-up keeps the feature active. Fixes features that otherwise sit "in-progress" forever after their delivering task completes. 2. **Re-point / unlink surface** — new `fn_feature_repoint_task` / `fn_feature_unlink_task` agent tools (engine + CLI) backed by an atomic `repointFeatureToTask` store primitive, so a mis-linked feature can be re-attached to the correct delivery task or unlinked — without a manual DB edit. Single-valued `feature.taskId` and one-feature-one-task invariants are preserved; unlinking an already-unlinked feature errors clearly. Classified as mutation tools, same class as the existing `fn_feature_link_task`. 3. **Live SSE update** — the `feature:unlinked` store event is now emitted over SSE (`event: feature:unlinked`) so the dashboard refreshes immediately after a re-point/unlink instead of waiting for the next poll. ## Why The forward-only `feature.taskId` link made three real failure modes unrecoverable from the product surface: stale done-features after task replacement, permanently mis-linked features, and a stale dashboard after a repair. This closes the feature lifecycle end-to-end. ## Invariants - `feature.taskId` stays single-valued; one feature is linked to at most one task at any time (atomic store primitive). - Done-credit requires: terminal column, non-failed, and no live lineage candidate. - No new run-audit prose; store events carry ids/counts/outcomes only. ## Tests - `mission-state-reconcile.test.ts` — reverse-lineage credit matrix (live vs. terminal vs. failed candidates) - `mission-store.pg.test.ts` — `repointFeatureToTask` atomicity + invariants (PG; gate-safe auto-skip without Postgres) - `agent-mission-tools.test.ts` — tool delegation (unlink / re-point exactly once) - `heartbeat-executor.test.ts`, `extension.test.ts` — tool exposure and heartbeat interaction - Changeset: `@runfusion/fusion: minor` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added tools to reassign a feature to another live task or remove its task link. - Unlinking resets the feature to a defined state and provides clear errors when applicable. - Added live updates for feature unlink events. - Improved reconciliation to recognize completed reverse-lineage work while respecting active follow-up tasks and failures. - Improved relationship consistency when concurrent task-link operations occur. - **Documentation** - Documented feature linking, unlinking, reassignment, lifecycle events, and reconciliation behavior. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Fusion <noreply@runfusion.ai>
Fusion Documentation
Fusion is an AI-orchestrated task board that turns ideas into reviewed, merged code using a structured workflow: planning → todo → in-progress → in-review → done.
Quick Start
Start the local dashboard with pnpm dev dashboard, then create your first task from the board or CLI.
