Make runAiMerge (the FN-5633 clean-room AI merge path, already the default) the sole merge path; soft-deprecate the legacy aiMergeTask pipeline. Phase 0 of the workspace-mode master plan — a standalone merge-consolidation refactor that lands first so downstream workspace work targets one merge function. U1 — collapse the dispatch: project-engine.ts now calls runAiMerge unconditionally; the two direct callers that bypassed the dispatch (dashboard.ts onMergeImpl in --no-engine mode, task.ts runTaskMerge / `fn task merge`) now route to runAiMerge too. Export runAiMerge from @fusion/engine. U2 — soft-deprecate: aiMergeTask is @deprecated (body retained for a later deletion pass; shared helpers runAiMerge imports, e.g. captureSingleCommitLandedMetadata, left intact). merger.mode "deterministic" is annotated deprecated and made inert (type + field kept — published @runfusion/fusion surface); the dispatch logs a one-time deprecation warning and routes to runAiMerge. Changeset added (minor). U3 — R7 workspace merge-boundary guard: shared @fusion/core predicate assertNotWorkspaceTaskMerge(task) rejects tasks with populated workspaceWorktrees at all four merge entry points (dispatch, store.mergeTask, onMergeImpl, runTaskMerge) with an error naming master-plan U6. Covers the window until per-repo merge support lands; U6 removes it. U4 — deterministic-mode blast-radius audit: no production project, CI config, or seeded setting pins merger.mode "deterministic"; only four engine tests used it to drive the dispatch to aiMergeTask as a mockable seam — migrated to mock runAiMerge instead. Other module-level aiMergeTask mocks were dead under the default "ai" mode or test aiMergeTask directly (body retained), so they are unaffected. Also removes an unused acquireWorkspaceRepoWorktree import inherited from the foundation branch (executor.ts) that was failing lint; master-plan U1 re-adds it with its per-repo usage. Merge gate green: lint, typecheck (29 projects), build, test:gate (649 + 58), plus the migrated (114) and new predicate (4) tests. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
For a full walkthrough (installation, onboarding, first task, and daily workflow basics):
