+# SciDK — Architecture & Status Handoff
+
+_Snapshot date: 2026-06-22 · Branch: `production-mvp` @ `23ba225` (the de-facto trunk)_
+
+> **Read this, not the root `README.md`.** The README has accreted ~2 years of per-cycle
+> notes and is partly stale (e.g. it still claims "in-memory graph, Neo4j not wired" — false;
+> Neo4j, a Concept Graph, and an MCP server are all wired in). This doc reflects the actual code.
+
+---
+
+## 1. What SciDK is
+A Flask web app for **scientific data management on top of a knowledge graph**. It scans
+filesystems (local, mounted, or rclone remotes), interprets files, builds a property graph in
+Neo4j, and exposes an LLM chat interface (ReAct + GraphRAG) over that graph, plus an MCP server
+so external agents (Claude Desktop, etc.) can query it.
+
+## 2. Branch / repo topology (important)
+- **`production-mvp`** is the real mainline — it contains all of `main` plus **320 commits** on top.
+- **`main`** is a **stale snapshot frozen at 2026-03-02** (last PR `#52`). The PR→main review flow
+ (PRs #32–#52, per `dev/README-planning.md`) stopped there. All March work (AI/Chat stack,
+ scanner, Cytoscape fixes) was committed **directly to `production-mvp` and never PR'd into main**.
+- **`dev/`** is a **git submodule** = the planning/docs repo (stories, phases, tasks, features;
+ see `dev/README-planning.md`). It is NOT app runtime code.
+
+## 3. Tech stack
+- **Backend:** Python 3.12, Flask (app-factory + blueprints), Swagger/flasgger at `/api/docs`,
+ `ProxyFix` for reverse-proxy/subpath deploys, gunicorn in prod (`restart_gunicorn.sh`).
+- **Graph DB:** Neo4j 5 (`docker-compose.neo4j.yml`; Bolt 7687 / HTTP 7474). In-memory graph
+ backend exists as a fallback (`SCIDK_STATE_BACKEND=memory`).
+- **Relational/state:** SQLite with WAL — multiple DBs: `scidk.db`, `scidk_settings.db`,
+ `scidk_path_index.db`. Auto-migrations run on boot (`scidk/core/migrations*`), reported via `/api/health`.
+- **LLM:** pluggable providers — Ollama / Anthropic / OpenAI (`scidk/ai/provider_factory.py`,
+ `llm_providers.py`). GraphRAG/embeddings stack is **optional** (`requirements-graphrag.txt`,
+ PyTorch+CUDA, gated by `SCIDK_GRAPHRAG_ENABLED`).
+- **Frontend:** server-rendered Jinja templates + vanilla JS; **Cytoscape.js** for graph viz
+ (`scidk/ui/static/js/graph_utils.js`, `SciDKGraph`).
+- **Tests:** pytest, 3 tiers via markers (`unit` / `integration` / `e2e`); Playwright for E2E.
+
+## 4. App initialization — `scidk/app.py::create_app()`
+Single application factory. Wires, in order:
+1. Logging, channel defaults, ProxyFix, Swagger.
+2. SQLite auto-migration; state-backend toggle (`sqlite` default).
+3. **Graph backend** (`core/neo4j_config.create_graph_backend` → Neo4j or in-memory).
+4. **Concept Graph driver** (optional, `SCIDK_CONCEPT_GRAPH_ENABLED=1`; graceful fallback to
+ hard-coded intent classifier if unavailable).
+5. Interpreter registry; FilesystemManager; FS providers (`local_fs`, `mounted_fs`, `rclone`).
+6. Everything hung off `app.extensions['scidk']` (graph, concept_driver, registry, fs, providers,
+ in-session registries for scans/tasks/directories, neo4j_config/state, rclone_mounts, settings).
+7. Hydrate persisted state from SQLite (last scan, rclone mounts/settings, Neo4j creds).
+8. Register **26 blueprints** (`web/routes/register_blueprints`); init auth middleware (RBAC).
+9. **Plugin system**: label-endpoint registry, plugin-template registry, plugin-instance manager,
+ plugin loader (discovers `plugins/`).
+10. Backup scheduler (also runs Concept Graph weight-decay job).
+
+## 5. Package layout (`scidk/`)
+- **`ai/`** — LLM layer. `react_loop.py` (ReAct agent), `chat_graph.py`, `summarization.py`,
+ `cypher_utils.py`, `mcp_tools.py`, `schema_context.py`, `provider_factory.py` / `llm_providers.py`.
+- **`services/`** — business logic. Key ones:
+ - `concept_graph_service.py` (~1k lines) — Concept Graph: semantic schema layer with weighted
+ edges + decay, export/import, intent routing.
+ - `schema_intelligence.py` (~675 lines) — editable schema intelligence (labels/profiles, embeddings).
+ - `chat_neo4j_client.py`, `chat_service.py` — DB-persisted chat with permissions.
+ - `graphrag/` (incl. `intent_classifier.py`) — LOOKUP vs REASONING routing, text-to-Cypher.
+ - `neo4j_client.py`, `query_service.py`, `link_service.py` / `link_service_v2.py`,
+ `label_service.py`, `fs_index_service.py`, `scan_index_service.py`, `commit_service.py`,
+ `saved_maps_service.py`, `metrics.py`.
+- **`web/routes/`** — 26 Flask blueprints (see §6). Pattern: `_get_ext()` to reach
+ `app.extensions['scidk']`; background work uses threads with captured `app.app_context()`.
+- **`core/`** — infra: migrations, neo4j/channel/rclone config, plugin loader + registries,
+ backup manager/scheduler, alert manager, settings, logging.
+- **`concept_graph/`** — `intents.yaml`, `schema.cypher` (Concept Graph seed/schema).
+- **`interpreters/`, `labels/`, `schema/`, `scripts/`, `export/`** — file interpreters, label
+ definitions, schema generation, script registry, exporters.
+- **`mcp_server.py`** — standalone MCP server (`python -m scidk.mcp_server`), 5 read-only tools:
+ `query_knowledge_graph`, `get_schema`, `summarize_dataset`, `get_label_profile`, `list_labels`.
+
+## 6. HTTP surface — 26 blueprints (`scidk/web/routes/`)
+UI (`ui.py`: `/`, `/datasets`, `/map`, `/chat`, `/settings`, …) + API blueprints:
+`api_files`, `api_graph`, `api_maps`, `api_scripts`, `api_tasks`, `api_chat`, `api_queries`,
+`api_neo4j`, `api_admin`, `api_interpreters`, `api_providers`, `api_annotations`, `api_labels`,
+`api_integrations`, `api_links` (legacy) + `api_links_v2` (LinkRegistry), `api_settings`,
+`api_auth`, `api_users`, `api_audit`, `api_alerts`, `api_logs`, `api_plugins`, `api_system`
+(chat self-awareness), `api_results`.
+_(The `web/routes/README.md` count of "9 blueprints / 91 routes" is outdated — it's 26 now.)_
+
+## 7. Major subsystems delivered (newest → older)
+- **AI / Chat stack (Mar 2026, production-mvp only):** Concept Graph (Phases 1–3: weighted edges,
+ decay, MCP tools, export/import), Schema Intelligence editable UI, ReAct streaming chat with
+ reasoning-block visualization, MCP server, Neo4j full-text indexes. Seed scripts at repo root
+ (`seed_concept_graph*.py`, `seed_schema_embeddings.py`, `apply_concept_schema.py`).
+- **Standalone filesystem scanner (Mar 2026):** `tools/scidk_scanner.py` + `_opt.py` —
+ magic-byte detection + parallel enumeration; spec in `tools/SCIDK_SCANNER_SPEC.md`.
+- **Cross-database transfer V2 (#51):** provenance, progress tracking, cancellation.
+- **Security (#40):** multi-user auth + RBAC + DB-persisted chat with permissions.
+- **Config backup/restore (#41) + auto-lock on inactivity (#44).**
+- **Plugins:** `plugins/{example_plugin, example_ilab, table_loader, ilab_table_loader}` —
+ UI-instantiable plugin templates + instances; the recent demo focused on the **iLab plugin +
+ concept-graph seeding** (see the `dev` submodule branch `feature/ilab-plugin-and-demo-seeding`).
+- **Providers:** rclone is core (feature flag removed, #31); FUSE mount manager under `./data/mounts/`.
+
+## 8. How to run
+```bash
+pip install -e .[dev] # or requirements.txt (lite) / requirements-graphrag.txt (AI)
+docker compose -f docker-compose.neo4j.yml up -d # Neo4j (default creds neo4j/neo4jiscool)
+scidk-serve # or: python -m scidk.app → http://127.0.0.1:5000
+python -m scidk.mcp_server # MCP server for external agents
+make unit | make integration | make e2e | make check # tests
+```
+Key env: `SCIDK_STATE_BACKEND` (sqlite|memory), `SCIDK_PROVIDERS`, `NEO4J_URI`/`NEO4J_AUTH`,
+`SCIDK_CONCEPT_GRAPH_ENABLED`, `SCIDK_GRAPHRAG_ENABLED`, `SCIDK_CHANNEL` (stable|dev), `SCIDK_BASE`
+(subpath deploys). `.env` is auto-loaded via python-dotenv.
+
+## 9. Open items / gotchas for the next agent
+1. **main is stale.** Decide whether to back-merge the March AI/Chat + scanner work from
+ `production-mvp` into `main`, or formally retire `main` in favor of `production-mvp`.
+2. **`dev` submodule diverges** (47 local-only vs 8 pinned-only commits) on
+ `feature/ilab-plugin-and-demo-seeding`. Reconcile before committing the superproject's `dev` pin.
+3. **Stale root `README.md`** — large sections describe an earlier MVP; trust this doc + code instead.
+4. **GraphRAG/AI features are optional and heavy** (PyTorch/CUDA) and degrade gracefully when off.
+5. Repo root holds loose scripts/artifacts (`seed_*.py`, `*.db`, `htmlcov/`, `pytest_fully_output.txt`)
+ that could use a cleanup pass.

## Architecture
SciDK uses a modular Flask blueprint architecture for web routes:
-- **9 blueprints** organize 91 routes by functional area (UI, files, tasks, graph, Neo4j, providers, chat, admin, interpreters)
-- **Reduced footprint**: app.py reduced from 5,781 to 645 lines (89% reduction)
+- **~27 blueprints** organize 300+ routes by functional area (UI, files, tasks, graph, Neo4j, providers, chat, labels, links, admin, interpreters, and more)
+- **Application factory**: `create_app()` lives in `scidk/app.py` (~314 lines); blueprints are registered via `register_blueprints()` in `scidk/web/routes/__init__.py`
- **Clean separation**: Each blueprint is self-contained with proper import scoping
- See `scidk/web/routes/README.md` for detailed blueprint documentation

## Neo4j integration
-- Status: The app ships with docker-compose.neo4j.yml to run a local Neo4j, but the Flask app currently uses an in-memory graph.
-- Next steps to enable Neo4j writes/reads:
- 1) Add a GraphAdapter interface and a Neo4jAdapter implementing upsert_dataset, add_interpretation, commit_scan, schema_triples.
- 2) Add config/feature flag (e.g., SCIDK_GRAPH_BACKEND=neo4j) to switch adapters.
- 3) Map current in-memory structures to Neo4j schema: (:File), (:Folder), (:Scan) nodes and CONTAINS, INTERPRETED_AS, SCANNED_IN relationships.
- 4) Use Cypher or APOC to compute schema triples for /api/graph/schema.
-- Until then, data is not persisted to Neo4j. Use the CSV exports or the in-memory map for the demo.
+- Status: Neo4j is fully wired. The app ships with docker-compose.neo4j.yml to run a local Neo4j; set `SCIDK_GRAPH_BACKEND=neo4j` (plus `NEO4J_URI`/`NEO4J_AUTH`) to persist to it. With the default in-memory backend, graph data is not persisted across restarts.
+- How it works:
+ - The graph backend is selected at startup in `create_app()` via `SCIDK_GRAPH_BACKEND` (`memory` default, `neo4j` to persist); invalid Neo4j params fall back to in-memory.
+ - Committing a scan writes `(:File)`, `(:Folder)`, `(:Scan)` nodes with `(Folder)-[:CONTAINS]->(File|Folder)`, `(File|Folder)-[:SCANNED_IN]->(Scan)`, and `INTERPRETED_AS` relationships, via `scidk/services/neo4j_client.py`.

+# Contributing to SciDK
+
+Conventions for common changes. For setup and how to run the app, see the README ("Run the server" — `scidk-serve` is canonical).
+
+## Add a new route
+
+Routes live in per-area blueprints under `scidk/web/routes/`. Reuse an existing module when one fits; otherwise add a new file following the same pattern:
+
+```python
+# scidk/web/routes/api_widgets.py
+from flask import Blueprint, jsonify
+bp = Blueprint("api_widgets", __name__, url_prefix="/api")
+
+@bp.get("/widgets")
+def list_widgets():
+ return jsonify([])
+```
+
+Then register it in `scidk/web/routes/__init__.py` inside `register_blueprints()`:
+
+```python
+from . import api_widgets
+app.register_blueprint(api_widgets.bp)
+```
+
+Add `data-testid` attributes to any new interactive UI elements.
+
+## Persist settings
+
+Use the helpers in `scidk/core/settings.py` — do not write the `settings` table directly:
+
+```python
+from scidk.core.settings import get_setting, set_setting
+set_setting("my_key", "value")
+val = get_setting("my_key", default=None)
+```
+
+## Query Neo4j
+
+Always go through `scidk/services/neo4j_client.py`; never instantiate `neo4j.GraphDatabase` drivers directly:
+
+```python
+from scidk.services.neo4j_client import get_neo4j_client
+client = get_neo4j_client()
+rows = client.execute_read("MATCH (n:File) RETURN count(n) AS c")
+client.execute_write("MERGE (:Tag {name: $name})", {"name": "demo"})
+```
+
+This centralizes connection params, auth modes, and profiles.
+
+## Add a migration
+
+Schema lives in `scidk/core/migrations.py` and auto-runs on boot. Append a new versioned block at the end of `migrate()` — never edit past blocks:
+
+```python
+if version < 26:
+ cur.execute("CREATE TABLE IF NOT EXISTS my_table (...);")
+ conn.commit()
+ _set_version(conn, 26)
+ version = 26
+```
+
+`files`/index schema lives in `scidk/core/path_index_sqlite.py`.
+
+## Logging
+
+Use a module-level logger; do not use `print()`:
+
+```python
+import logging
+logger = logging.getLogger(__name__)
+logger.info("scan started: %s", path)
+```

+# SciDK MCP Server Setup
+
+The SciDK MCP (Model Context Protocol) server exposes core SciDK functionality to external AI agents like Claude Desktop.
+
+## Features
+
+The MCP server provides 5 core tools:
+
+1. **`query_knowledge_graph`** — Execute safe read-only Cypher queries against the Neo4j knowledge graph
+2. **`get_schema`** — Retrieve the current database schema (labels, relationships, properties)
+3. **`summarize_dataset`** — Generate statistical summaries of labels/relationships
+4. **`get_label_profile`** — Get detailed Schema Intelligence profiles for specific labels
+5. **`list_labels`** — List all labels with node counts
+
+All tools return structured JSON responses and enforce read-only safety (no CREATE/MERGE/DELETE operations).
+
+## Installation
+
+### 1. Install MCP SDK
+
+```bash
+pip install mcp>=1.0.0
+```
+
+This is already included in `requirements.txt`.
+
+### 2. Configure Claude Desktop
+
+Add the following to your Claude Desktop configuration file:
+
+**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
+**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
+**Linux**: `~/.config/Claude/claude_desktop_config.json`
+
+```json
+{
+ "mcpServers": {
+ "scidk": {
+ "command": "python3",
+ "args": ["-m", "scidk.mcp_server"],
+ "cwd": "/path/to/scidk",
+ "env": {
+ "NEO4J_URI": "bolt://localhost:7687",
+ "NEO4J_USER": "neo4j",
+ "NEO4J_PASSWORD": "neo4jiscool",
+ "NEO4J_DATABASE": "neo4j"
+ }
+ }
+ }
+}
+```
+
+**Important**: Replace `/path/to/scidk` with the absolute path to your SciDK installation.
+
+### 3. Restart Claude Desktop
+
+After updating the config, restart Claude Desktop completely. The MCP server will start automatically when you open a new conversation.
+
+## Testing
+
+### Manual Test
+
+You can test the MCP server directly from the command line:
+
+```bash
+# Start the server (it uses stdio transport)
+python3 -m scidk.mcp_server
+```
+
+The server will connect to Neo4j and wait for MCP protocol messages on stdin.
+
+### Test in Claude Desktop
+
+Once configured, open Claude Desktop and try these queries:
+
+1. **List available labels:**
+ ```
+ Use the list_labels tool to show me all labels in the database
+ ```
+
+2. **Get schema:**
+ ```
+ Use get_schema to show me the database structure
+ ```
+
+3. **Query the graph:**
+ ```
+ Use query_knowledge_graph to run: MATCH (f:File) RETURN f.name LIMIT 5
+ ```
+
+4. **Get label profile:**
+ ```
+ Use get_label_profile to analyze the File label
+ ```
+
+## Tool Usage Examples
+
+### 1. query_knowledge_graph
+
+Execute a read-only Cypher query:
+
+```json
+{
+ "cypher": "MATCH (f:File) WHERE f.mime_type CONTAINS 'image' RETURN f.name, f.path LIMIT 10",
+ "limit": 10
+}
+```
+
+Returns:
+```json
+{
+ "status": "success",
+ "rows": [
+ {"f.name": "image1.png", "f.path": "/data/images/image1.png"},
+ ...
+ ],
+ "row_count": 10,
+ "error": null
+}
+```
+
+### 2. get_schema
+
+Retrieve database schema:
+
+```json
+{
+ "max_labels": 50,
+ "max_props_per_label": 5
+}
+```
+

+```json
+{
+ "status": "success",
+ "schema": {
+ "labels": ["File", "Folder", "Scan", "Sample", "SampleType"],
+ "relationships": ["CONTAINS", "DERIVED_FROM", "SCANNED_IN"],
+ "properties": {
+ "File": ["name", "path", "mime_type", "size", "created"],
+ "Folder": ["name", "path", "host", "host_id"]
+ },
+ "label_counts": {
+ "File": 1523,
+ "Folder": 342,
+ ...
+ }
+ },
+ "error": null
+}
+```
+
+### 3. list_labels
+
+Get all labels with counts:
+
+```json
+{}
+```
+
+Returns:
+```json
+{
+ "status": "success",
+ "labels": [
+ {"name": "File", "count": 1523},
+ {"name": "Folder", "count": 342},
+ {"name": "Scan", "count": 89},
+ {"name": "Sample", "count": 45},
+ {"name": "SampleType", "count": 12}
+ ],
+ "error": null
+}
+```
+
+### 4. get_label_profile
+
+Get detailed profile for a label:
+
+```json
+{
+ "label": "File"
+}
+```
+
+Returns:
+```json
+{
+ "status": "success",
+ "profile": {
+ "label": "File",
+ "node_count": 1523,
+ "properties": [
+ {"name": "name", "frequency": 1523},
+ {"name": "path", "frequency": 1523},
+ {"name": "mime_type", "frequency": 1521},
+ {"name": "size", "frequency": 1520},
+ {"name": "created", "frequency": 1518}
+ ],
+ "relationships": [
+ {"type": "CONTAINS", "target": "Folder", "frequency": 1523},
+ {"type": "DERIVED_FROM", "target": "Sample", "frequency": 342}
+ ]
+ },
+ "error": null
+}
+```
+
+### 5. summarize_dataset
+
+Generate statistical summary:
+
+```json
+{
+ "label": "File"
+}
+```
+
+Returns:
+```json
+{
+ "status": "success",
+ "summary": "Dataset summary: {'node_count': 1523, 'label': 'File'}",
+ "error": null
+}
+```
+
+## Safety Features
+
+The MCP server enforces strict safety rules:
+
+- **Read-only queries**: Blocks CREATE, MERGE, DELETE, SET, DROP, DETACH keywords
+- **Automatic LIMIT**: Adds `LIMIT 50` to queries without explicit limits
+- **Error handling**: Returns structured error messages instead of crashing
+- **Connection pooling**: Uses Neo4j driver connection pooling for efficiency
+
+## Troubleshooting
+
+### MCP server not appearing in Claude Desktop
+
+1. Check the Claude Desktop config file path
+2. Verify JSON syntax is valid (use a JSON validator)
+3. Check that the `cwd` path is correct
+4. Restart Claude Desktop completely (quit and reopen)
+
+### Connection errors
+
+1. Verify Neo4j is running: `docker ps | grep neo4j`
+2. Test connection manually: `python3 -m scidk.mcp_server`
+3. Check environment variables in config
+4. Verify Neo4j credentials are correct
+
+### Tools not working
+
+1. Check the Claude Desktop logs (varies by platform)
+2. Verify the MCP server can import scidk modules
+3. Test tools directly via Python:
+ ```python
+ from scidk.ai import mcp_tools
+ from neo4j import GraphDatabase
+
+ driver = GraphDatabase.driver("bolt://localhost:7687", auth=("neo4j", "neo4jiscool"))
+ result = mcp_tools.list_labels(driver, "neo4j")
+ print(result)
+ ```
+
+## Next Steps
+
+Once the MCP server is working, these tools can be integrated into the Concept Graph Phase 3 as `:Concept_Tool` nodes. The Concept Graph will then route user intents to MCP tools alongside native SciDK tools, creating a unified planning layer.
+
+See the [SciDK Architecture Vision](SciDK_Architecture_Vision.md) for the full integration plan.

+# Rclone Setup
+
+Ops reference for configuring rclone remotes used by a SciDK instance. For UI/API usage of the rclone provider see [`docs/rclone/quickstart.md`](rclone/quickstart.md); for FUSE mounts see [`docs/rclone/mount-examples.md`](rclone/mount-examples.md).
+
+## Install rclone
+
+Install from the official package (do not vendor the binary). See .
+
+```bash
+# Linux
+curl https://rclone.org/install.sh | sudo bash
+# macOS
+brew install rclone
+
+rclone version
+```
+
+SciDK shells out to whatever `rclone` is on `PATH` (`shutil.which('rclone')`). It must be installed on the same host as the SciDK process — not just inside a container the app cannot reach.
+
+## How SciDK uses rclone
+
+`RcloneProvider` (`scidk/core/providers.py`) drives the `rclone` CLI directly:
+
+- **Discover remotes:** `rclone listremotes` → populates the provider roots (each line like `dropbox:`).
+- **Browse / scan:** `rclone lsjson ` → JSON entries (`Name`, `Path`, `Size`, `IsDir`) consumed by the scan loop.
+- **Fetch content:** `rclone cat ` via `provider.cat()` / `provider.open()`.
+
+Any remote you create with `rclone config` is therefore visible to SciDK automatically — there is no separate SciDK-side remote registry. Enable the provider with:
+
+```bash
+export SCIDK_PROVIDERS=local_fs,mounted_fs,rclone
+```
+
+Verify a remote is reachable before scanning:
+
+```bash
+rclone listremotes # SciDK sees exactly these
+rclone lsjson : # what a scan will enumerate
+```
+
+## Configuring remotes
+
+Run `rclone config` and follow the interactive prompts. Below are the three remote types used in this deployment. OAuth backends (SharePoint, Dropbox) need a browser for the initial token grant — if configuring on a headless server, run `rclone authorize` on a machine with a browser and paste the token, or use `rclone config` over an SSH tunnel.
+
+### SharePoint (Microsoft OneDrive provider)
+
+SharePoint document libraries are accessed through rclone's `onedrive` backend.
+
+```bash
+rclone config
+# n) New remote
+# name> sharepoint
+# Storage> onedrive
+# Leave client_id / client_secret blank to use rclone's defaults
+# region> 1 (Microsoft Cloud Global)
+# Use auto config? > y (opens browser for OAuth)
+# Then choose the site type:
+# - "SharePoint site" / "Search for a SharePoint site"
+# - enter the site name or URL, pick the document library (drive)
+```
+
+Confirm:
+
+```bash
+rclone lsd sharepoint:
+```
+
+### Dropbox
+
+```bash
+rclone config
+# n) New remote
+# name> dropbox
+# Storage> dropbox
+# Leave client_id / client_secret blank
+# Use auto config? > y (opens browser for OAuth)
+```
+
+Confirm:
+
+```bash
+rclone lsd dropbox:
+```
+
+### SFTP or mounted path (e.g. `/mnt/server`)
+
+For a local mount (NFS/CIFS already mounted by the OS, like the BMC-Lab6 archive at `/mnt/server`), you do **not** need an rclone remote at all — use SciDK's `mounted_fs` provider and point a scan at the path directly.
+
+To reach a server over SSH instead, configure an SFTP remote:
+
+```bash
+rclone config
+# n) New remote
+# name> server
+# Storage> sftp
+# host> server.example.mit.edu
+# user>
+# port> 22
+# Auth: key_file> /home/scidk/.ssh/id_ed25519 (preferred)
+# or set a password
+```
+
+Confirm:
+
+```bash
+rclone lsd server:/path/to/data
+```
+
+## Reconnecting an expired OAuth token
+
+OAuth backends (SharePoint, Dropbox) hold refresh tokens that can expire or be revoked. Scans then fail with auth errors. Re-grant access without recreating the remote:
+
+```bash
+rclone config reconnect sharepoint:
+rclone config reconnect dropbox:
+```
+
+This reopens the browser OAuth flow and rewrites the token in place. Verify afterward with `rclone lsd :`.
+
+## Troubleshooting
+
+Diagnose any failure by reproducing the exact call SciDK makes, with verbose logging:
+
+```bash
+rclone lsjson : -vv
+```
+
+| Symptom | Likely cause | Fix |
+|---|---|---|
+| `rclone not installed or not on PATH` from SciDK | `rclone` not visible to the app's user/environment | Install rclone for the SciDK service user; confirm `which rclone` |
+| Remote missing from SciDK provider roots | Not in `rclone listremotes`, or `rclone` is a different config/user | Check `rclone config file` location; run `rclone listremotes` as the SciDK user |
+| `401`/`403` / `token expired` / `invalid_grant` | OAuth token expired or revoked | `rclone config reconnect :` |
+| `directory not found` / empty `lsjson` | Wrong path, or backend has no folder placeholders | Verify with `rclone lsd :`; check casing and the document-library name |
+| Hang or timeout on large dirs | Backend slow to enumerate recursively | Scan with a bounded depth, or try `--fast-list` (provider retries without it on failure) |
+| `couldn't connect SSH` | SFTP host/key/firewall | Test `ssh user@host`; confirm `key_file` path and permissions (`600`) |
+
+Useful checks:
+
+```bash
+rclone config file # which config is in effect
+rclone config show # inspect a remote's settings (redacts secrets)
+rclone about : # quota / connectivity sanity check
+```
