# Production readiness roadmap

Status: implementation started; no production release yet. Windows VM tests use CPU only.

## 1. Search foundation
- [x] Rust workspace, reusable engine, CLI, versioned SQLite storage.
- [ ] Filename/path and ranked full-text retrieval with strict filters.
- [ ] Safe folder discovery, exclusions, bounded extraction, passage locations.
- [ ] Incremental updates, rename/deletion reconciliation, crash recovery.
- [x] Persistence and filesystem lifecycle integration tests (Windows CPU).

## 2. Document and semantic retrieval
- [ ] Text, Markdown, code, PDF and DOCX extraction with fixtures.
- [ ] Validate actual embedding model artifacts, license, CPU runtime and quantization.
- [ ] Versioned embeddings, ANN index, exact-match priority and hybrid fusion.
- [ ] English/German relevance corpus and measured top-10 recall.
- [ ] Atomic model/index replacement and resumable persistent work queues.

## 3. Desktop
- [ ] Tauri shell, accessible keyboard search, progressive results and previews.
- [ ] Folder selection, exclusion controls, resource budgets and indexing status.
- [ ] Global shortcut, opening/revealing source files, PDF page navigation.
- [ ] Watchers and reconciliation across Windows, macOS and Linux.

## 4. Media
- [ ] CPU OCR, image retrieval, audio transcription, video segment locations.
- [ ] Isolated extraction workers with timeouts and resource ceilings.

## 5. Release gates
- [ ] Formatting, lint, tests and security/dependency review.
- [ ] CPU benchmarks: filename p95 <50 ms/1M records; text <150 ms/100K documents; semantic <500 ms on declared hardware.
- [ ] Measure cold start, indexing throughput, RAM, disk and idle CPU.
- [ ] Test migrations, interrupted work, invalid documents, inaccessible/offline roots and cloud placeholders.
- [ ] Automated native build matrix and documented supported cross-compilation paths.
- [ ] Execute Linux/macOS platform tests; create Windows/macOS/Linux installers.
- [ ] Signing/notarization configuration, upgrade/rollback validation, release instructions.

Completion requires recorded evidence; targets are not measured results.

## Completed foundation details

- SQLite FTS5 with exact filename priority, text snippets and strict filters.
- Default directory exclusions and protection against indexing the index itself.
- Metadata reuse, atomic root reconciliation and schema-v1 migration coverage.
- Actual CLI process integration tests and independent-reader concurrency test.
- TypeScript desktop frontend build and dependency audit passed; native validation underway.
- Initial README commit pushed to Gitea main via protected Infisical injection.

The partial features above do not close broader production milestones such as
crash-resumable jobs, fuzzy retrieval, watcher reliability or performance targets.
