## Summary Adds the **Stash memory backend** (`memory.backendType=stash`) that connects Fusion's agent memory to the [Stash](https://github.com/Fergana-Labs/stash) product — *knowledge bases for the agent era* ([product site: joinstash.ai](https://joinstash.ai)). Fusion becomes a first-class Stash client: complete chat sessions and finished tasks are captured into Stash, memory is recalled during chat, and Stash sessions are kept in sync with the dashboard (including deletes and archival). **Product:** <https://github.com/Fergana-Labs/stash> · [joinstash.ai](https://joinstash.ai) ## What's included ### 1. Stash memory backend (RUFU-068 / RUFU-121) - New `StashMemoryBackend` (`memory.backendType=stash`) with `stashUrl` / `stashApiKey` settings (global secrets-store `stash-api-key` + per-project override). - **Complete-chat-session capture** keyed by ChatSession id. - Sessions are classified into **per-project folders** (get-or-create, `external_key fusion-<projectId>`, 1h per-process cache) and **soft-deleted with their chat** via `DELETE /api/chat/sessions/:id`. - Per-conversation **memory-focus** read-time scoping (new `0066_chat_session_memory_focus.sql` migration — sequence renumbered 0059→0060→0061→0065→0066 as origin/main claimed the lower numbers); event metadata enriched with `project` / `project_name` / `chat_title`. - Recall queries normalized to single-keyword / explicit-OR ASCII (≤100 chars); shared normalizer export reused by per-turn recall. ### 2. Per-task executor transcript capture (RUFU-122) Finished or failed tasks upload their executor transcript (`agent-log.jsonl`) to Stash as a task session. ### 3. Bulk archive Stash sync (RUFU-125) Archived task-planner chats soft-delete their Stash sessions on bulk archival (paged). The snapshot of doomed session ids is taken *before* the local bulk delete, and the Stash sync runs fire-and-forget so a Stash stall can never delay local archival. ### 4. Per-chat "Preserve to Stash" backfill (RUFU-136) A per-chat action that backfills a chat's full history into Stash, with client-side idempotency and a pre-check that skips already-uploaded content (fail-closed, no duplicate upload on transport failure). - **Session-folder naming fix:** the first project folder is now named "Fusion — <project name>" instead of the bare "Fusion" fallback (the backfill now resolves the central-registry project name, best-effort, never blocking the upload). ### 5. Opt-in semantic (vector) recall (RUFU-126) `stashVectorSearch` setting (default `false` — **zero behavior change until enabled**). For multi-word queries the backend tries Stash's semantic-search endpoint first, then falls back byte-identically to the keyword path. Definitive 404/405/501/503 responses are negatively cached per process. Requires a patched Stash server (new endpoint + `sentence-transformers` + embedding backfill); unpatched servers are transparently bypassed after the first 404. ## Safety - **Opt-in / inert by default:** the default backend remains `qmd`; the Stash backend is inert until `memoryBackendType=stash` + `stashUrl` are set. - All Stash I/O is **best-effort, fail-closed, and non-blocking** — a Stash outage never blocks chat, task completion, or archival. No run-audit content is emitted. ## Testing - Backfill + delete-sync suites (20/20), Stash backend suite (68/68), executor memory / session capture suites, `memory-focus-recalling`, description-guard — all green. - `tsc` clean across core / engine / dashboard. - Live verification: bulk backfill of 21/24 chats completed; the "Preserve to Stash" action is idempotent on re-run. ## Changesets - `@runfusion/fusion` **minor** — Stash memory backend + capture (RUFU-068/121), per-task transcript (RUFU-122), bulk archive sync (RUFU-125), per-chat backfill (RUFU-136), opt-in vector search (RUFU-126) - `@runfusion/fusion` **patch** — backfill session-folder naming fix ## Rebase Note (2026-08-23) Rebased onto `origin/main` `3f448f7292` (v0.77.0-beta.7). Conflicts resolved additively: - `packages/core/src/postgres/schema-applier.ts` + test — upstream's 0062-0065 migrations (task/subtask splitting removal, AI merge review reconciliation, task repository scope, FN-149 review convergence) unioned with this PR's `chat_sessions.memory_focus` migration, which is **renumbered 0065 → 0066** (upstream's FN-149 shipped 0065 canonically on origin/main); `SCHEMA_BASELINE_VERSION` advances to `0066`. - `packages/dashboard/app/components/ChatView.tsx` — upstream's docked chat sidebar resize handlers unioned with the RUFU-136 "Preserve to Stash" backfill handler. - New commit: `settings.memory.*` stash-backend i18n keys added to all 6 secondary locales (RUFU-121/122 parity fix; `pnpm i18n:status` no longer reports any violation introduced by this PR). **Deploy note (operator environments that already ran a pre-rebase build of this PR):** the memory-focus SQL may already be in the schema under ledger row `0065`. Remap that row to `0066` (`UPDATE fusion_schema_migrations SET version = '0066' WHERE version = '0065';`) *before* first boot of a 0066-ceiling binary — otherwise the fresh upstream `0065_fn_149_review_convergence_stage.sql` would be skipped as "already applied". Clean databases (no prior memory-focus row) need no action. **CI note — Lint (lifecycle-column census) is red on the merge base:** `pnpm check:lifecycle-columns --strict` fails identically on pure `origin/main` `3f448f7292` with `packages/core/src/db/legacy-adoption.ts: 0 -> 3` (3 column guards in the U9b legacy-adoption table without a baseline entry or `DELIBERATE-LITERAL` marker). Verified by running the census on a clean origin/main checkout — inherited from the base, not introduced by this PR. Fix belongs upstream; tracked separately. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added Stash memory integration with project configuration and optional semantic search. * Added per-chat memory focus controls and a `/focus` command. * Added “Preserve to Stash” for uploading complete chat history. * Added automatic chat, task transcript, and completion-event capture. * Added project-specific Stash session folders and archive/delete synchronization. * **Bug Fixes** * Improved Stash folder naming and handling of missing branches during no-commit tasks. * **Documentation** * Added setup, configuration, integration, vector-search, and performance guidance. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Fusion <noreply@runfusion.ai> Co-authored-by: gsxdsm <gsxdsm@users.noreply.github.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.
