+## Coverage roadmap
+
+This is the living plan for what still needs tests. Keep it updated whenever a
+bug is fixed, a new module is added, or a planned area becomes covered.
+
+Status meanings:
+- ✅ Covered enough for current risk
+- 🟨 Basic coverage exists, important edge cases remain
+- ⬜ Not covered yet
+- 🔴 Regression target from a real bug
+
+### Phase 7 — Recent Regression Coverage
+
+| Priority | Area | Target tests | Status |
+|---|---|---|---|
+| P0 | `navi.content_store.ensure_tables()` | creates `session_content`, creates `idx_session_content_file`, is idempotent when index already exists | ⬜ |
+| P0 | `navi.content_store.publish()` | repeated publish of same `(session_id, filename)` updates one row instead of creating duplicates | ⬜ 🔴 |
+| P0 | `navi.main` startup | registries are initialized before `_check_embed()` so memory has an embedding backend | ⬜ 🔴 |
+| P0 | `navi.core.registry._discover_backends()` | primary Ollama backend receives HTTP timeout >= `LLM_COMPLETE_TIMEOUT` and `LLM_STREAM_FIRST_CHUNK_TIMEOUT` | ⬜ 🔴 |
+| P0 | `navi.llm.fallback.FallbackOllamaBackend` | per-server `OllamaBackend` clients receive the same expanded timeout | ⬜ 🔴 |
+| P1 | `navi.tools.content_publish` | missing file, directory instead of file, successful publish metadata, filename path stripping | ⬜ |
+| P1 | `navi.tools.share_file` | duplicate filename collision produces numbered output without overwrite | ⬜ |
+| P1 | `navi.api.routes.sessions` file endpoints | upload duplicate naming, forbidden extension, download path traversal, content disposition | 🟨 |
+
+### Phase 8 — Agent Loop Behavior
+
+| Priority | Area | Target tests | Status |
+|---|---|---|---|
+| P0 | `Agent.run_stream()` planning entry | first user message forces planning; later messages follow `planning_enabled` | ⬜ |
+| P0 | plan → todo bridge | numbered plan steps auto-populate todo exactly once per plan | ⬜ |
+| P0 | stop handling | stop during stream prefill yields `StreamStopped` and closes LLM generator | 🟨 |
+| P1 | subagent forwarding | parent forwards subagent tool events and counts subagent tokens/tool calls | ⬜ |
+| P1 | adaptive replan | newly failed todo step injects replan prompt on next iteration | ⬜ |
+| P1 | anti-stall | repeated tool calls or no todo progress inject warning after threshold | ⬜ |
+| P1 | workers | post-turn workers run after `StreamEnd`; worker failure is logged and non-fatal | ⬜ |
+
+### Phase 9 — Memory And Embeddings
+
+| Priority | Area | Target tests | Status |
+|---|---|---|---|
+| P0 | embedding backend wiring | `get_registries()` wires dedicated `EMBEDDING_OLLAMA_HOST` backend into `MemoryStore` | ⬜ |
+| P0 | pgvector detection | `_has_pgvector()` true/false paths and caching behavior | ⬜ |
+| P1 | embedding generation | invalid/empty/NaN vectors are skipped before PostgreSQL update | 🟨 |
+| P1 | backfill | `backfill_embeddings()` batches rows and only updates rows with valid vectors | 🟨 |
+| P1 | search | vector search falls back to ILIKE when vector search unavailable or empty | 🟨 |
+
+### Phase 10 — WebSocket And API Lifecycles
+
+| Priority | Area | Target tests | Status |
+|---|---|---|---|
+| P0 | active run guard | duplicate message while a run is active returns `run_already_active` | 🟨 |
+| P0 | reconnect replay | reconnect receives missed events and session sync after finished run | 🟨 |
+| P1 | stop endpoint | `POST /sessions/{id}/stop` sets stop event and is idempotent | 🟨 |
+| P1 | malformed input | oversize images, invalid file refs, and non-string payloads are rejected or sanitized | ⬜ |
+| P1 | startup cleanup | session file cleanup task is started once and deletes orphaned dirs | ⬜ |
+
+### Phase 11 — Frontend
+
+| Priority | Area | Target tests | Status |
+|---|---|---|---|
+| P0 | `ContentCard.vue` | renders download links and inline viewer links; handles encoded filenames | ⬜ |
+| P0 | streaming chat | auto-scroll and streaming message updates stay reactive | 🟨 |
+| P1 | session switching | concurrent session loads cannot overwrite active session with stale response | 🟨 |
+| P1 | error surfaces | API/store failures show recoverable UI state, no unhandled rejection | 🟨 |
+| P1 | file upload UI | upload success/failure, duplicate names, large-file errors | ⬜ |
+
