Ped-AI is a pediatric clinical documentation, education, and bedside decision-support app. This fork has moved well beyond the original scribe app: it now combines encounter documentation, clinical workflows, Learning Hub CMS, admin controls, MCP-backed clinical assistant integration, Redis-backed operational state, and hardened deployment defaults.
-The app runs as an authenticated Express/Postgres service with a browser frontend and optional integrations for LiteLLM, Vertex/Gemini, AWS, OpenAI-compatible APIs, Nextcloud WebDAV, S3-compatible storage, OpenBao, Redis, OIDC, TOTP, and Cloudflare Turnstile.

-# Architecture
-
-This document is the current high-level map for Ped-AI. It is intentionally shorter and more operational than the older deep-dive files under `docs/logic/`.
-
-## System Shape
-
-Ped-AI is a self-hosted Express application with a browser frontend, PostgreSQL storage, Redis operational state, LiteLLM model routing, and optional MCP-backed clinical retrieval.
-
-| Area | Owner | Notes |
-|---|---|---|
-| Web app | Ped-AI | Auth, UI, clinical workflows, admin settings, notes, Learning Hub, bedside tools |
-| Database | PostgreSQL | Users, sessions, settings, saved app data, audit/API/access logs |
-| Operational cache | Redis | Prompt suggestions, lightweight state, queue groundwork; not clinical answer caching |
-| Model gateway | LiteLLM | Text, speech, image, embedding model discovery and routing |
-| Clinical retrieval | MCP service | Nextcloud access, indexing, search, rerank, source metadata |
-| Reverse proxy | Caddy or equivalent | TLS and public routing |
-
-## Request Flow
-
-Normal app request:
-
-```txt
-browser
- -> reverse proxy
- -> Express middleware
- -> auth/session check when protected
- -> route handler
- -> PostgreSQL/Redis/provider calls as needed
- -> JSON or HTML fragment response
-```
-
-Clinical Assistant request:
-
-```txt
-browser
- -> Ped-AI clinical assistant route
- -> MCP semantic search for indexed clinical sources
- -> Ped-AI builds grounded answer prompt
- -> LiteLLM chat model
- -> Ped-AI returns answer plus source metadata
- -> browser renders markdown, citations, and source cards
-```
-
-Ped-AI owns the user workflow and rendering. MCP owns retrieval and indexed source metadata. LiteLLM owns model routing.
-
-## Runtime Boundaries
-
-| Boundary | Main Risk | Current Direction |
-|---|---|---|
-| Browser to Ped-AI | XSS, stale shell, session handling | Sanitized rendering, httpOnly cookie for web, cache busting |
-| Ped-AI to PostgreSQL | schema drift, slow queries | migrations, maintenance checks, indexes where needed |
-| Ped-AI to Redis | unavailable operational state | Redis is useful but should not hold required clinical answers |
-| Ped-AI to LiteLLM | provider downtime, wrong model mode | metadata-based model discovery and timeouts |
-| Ped-AI to MCP | retrieval latency/failure | explicit MCP client layer and graceful fallback messages |
-| MCP to Nextcloud | stale indexed metadata | scanner/indexer updates source metadata over time |
-
-## Source Of Truth
-
-| Data | Source Of Truth |
-|---|---|
-| User accounts and sessions | Ped-AI PostgreSQL |
-| Admin app settings | Ped-AI PostgreSQL `app_settings` |
-| Clinical source documents | Nextcloud and MCP index |
-| Clinical source title/path shown to users | MCP result metadata, especially indexed `file_path` |
-| Clinical answer text | Generated per request; intentionally not cached |
-| Model availability | LiteLLM metadata and configured fallbacks |
-
-## Deployment Shape
-
-Production usually runs:
-
-```txt
-Caddy/TLS
- -> pediatric-ai-scribe container
- -> pedscribe-db container
- -> ped-ai-redis container
- -> LiteLLM endpoint
- -> MCP endpoint
-```
-
-The app should stay private behind the reverse proxy. Do not expose PostgreSQL, Redis, MCP internals, or provider keys publicly.
-
-## Design Principles
-
-- Keep Ped-AI stateless enough to run more than one app container.
-- Keep clinical answer generation live and source-grounded; do not cache final clinical answers.
-- Prefer model capability metadata over model-name regexes.
-- Prefer indexed file names and paths over embedded PDF metadata for source titles.
-- Keep renderer fixes narrow and tested because LLM markdown is messy.
-- Keep old frontend globals working until the affected feature is intentionally converted to ESM.

-# Development
-
-This is the practical guide for changing Ped-AI safely.
-
-## Local Start
-
-```bash
-cp .env.example .env
-./scripts/build-image.sh
-docker compose up -d --no-build
-curl -fsS http://127.0.0.1:3552/api/health
-```
-
-Use Node 24 LTS. Run a locked install and tests from the repository root:
-
-```bash
-npm ci
-npm test
-```
-
-Run a focused syntax check when touching backend entrypoints:
-
-```bash
-node --check server.js
-node --check src/routes/clinicalAssistant.js
-```
-
-## Code Map
-
-| Path | Purpose |
-|---|---|
-| `server.js` | Express entrypoint, middleware, static serving, route mounting |
-| `src/routes/` | API route handlers |
-| `src/utils/ai.js` | Text model routing through configured providers |
-| `src/utils/clinicalAnswer.js` | Clinical Assistant answer prompt and source-grounding rules |
-| `src/utils/clinicalRetrieval.js` | MCP result normalization and source title cleanup |
-| `src/utils/clinicalMcpClient.js` | MCP streamable HTTP client/session handling |
-| `src/utils/litellm.js` | LiteLLM API/admin header helpers |
-| `src/db/database.js` | PostgreSQL pool and compatibility helpers |
-| `public/js/app.js` | SPA shell, tab loading, shared browser actions |
-| `public/js/admin.js` | Admin panel logic |
-| `public/js/assistant/` | Clinical Assistant rendering, sources, images, export, API helpers |
-| `public/js/learningHub/` | Newer modular Learning Hub frontend code |
-| `test/` | Node test suite and frontend module regression tests |
-
-## Change Workflow
-
-1. Read the relevant route, utility, frontend module, and tests before editing.
-2. Make the smallest correct change.
-3. Add or update a regression test when changing clinical rendering, model routing, auth, settings, or source handling.
-4. Run focused tests first if available.
-5. Run `npm test` before deploy or commit.
-6. Deploy with Docker only after tests pass.
-7. Verify `/api/health` after deploy.
-
-## Clinical Assistant Changes
-
-Clinical Assistant changes should usually include tests because small rendering or prompt changes can affect clinical trust.
-
-High-risk areas:
-
-- citation linking,
-- table rendering,
-- source title cleanup,
-- named-source provenance rules,
-- image intent detection,
-- MCP result normalization,
-- provider/model selection.
-
-When a real answer renders badly, save a de-identified example as a fixture or direct test input. Do not make broad global repairs that convert arbitrary numbers into citation links.
-
-## Frontend Rendering Rules
-
-Use `textContent` for plain text. Use `innerHTML` only for static templates, sanitized markdown, or HTML built entirely from escaped values.
-
-Safe patterns:
-
-```js
-el.textContent = userText;
-el.innerHTML = escapeHtml(userText).replace(/\n/g, '
');
-el.innerHTML = sanitizeHtml(renderMarkdown(modelOutput));
-```
-
-Unsafe pattern:
-
-```js
-el.innerHTML = modelOutput;
-```
-
-If a dynamic value enters an HTML string, escape it at the point of insertion. If it is an attribute value, escape quotes too.
-
-## Deployment Checks
-
-After deployment:
-
-```bash
-curl -fsS http://127.0.0.1:3552/api/health
-docker compose ps pediatric-scribe
-```
-
-If the browser still shows old frontend behavior, force-refresh or check the injected `BUILD_ID` asset query string.
-
-## Documentation Expectations
-
-Keep docs close to operational truth. If a behavior changes, update the most specific doc in the same change. Prefer short, current docs over long historical explanations.

+| Database | PostgreSQL | Users, sessions, settings, saved app data, audit/API/access logs |
+| Operational cache | Redis | Prompt suggestions, lightweight state, queue groundwork; not clinical answer caching |
+| Model gateway | LiteLLM | Text, speech, image, embedding model discovery and routing |
+| Clinical retrieval | MCP service | Nextcloud access, indexing, search, rerank, source metadata |
+| Reverse proxy | Caddy or equivalent | TLS and public routing |
+
+### Request Flow
+
+Normal app request:
+
+```txt
+browser
+ -> reverse proxy
+ -> Express middleware
+ -> auth/session check when protected
+ -> route handler
+ -> PostgreSQL/Redis/provider calls as needed
+ -> JSON or HTML fragment response
+```
+
+Clinical Assistant request:
+
+```txt
+browser
+ -> Ped-AI clinical assistant route
+ -> MCP semantic search for indexed clinical sources
+ -> Ped-AI builds grounded answer prompt
+ -> LiteLLM chat model
+ -> Ped-AI returns answer plus source metadata
+ -> browser renders markdown, citations, and source cards
+```
+
+Ped-AI owns the user workflow and rendering. MCP owns retrieval and indexed source metadata. LiteLLM owns model routing.
+
+### Runtime Boundaries
+
+| Boundary | Main Risk | Current Direction |
+|---|---|---|
+| Browser to Ped-AI | XSS, stale shell, session handling | Sanitized rendering, httpOnly cookie for web, cache busting |
+| Ped-AI to PostgreSQL | schema drift, slow queries | migrations, maintenance checks, indexes where needed |
+| Ped-AI to Redis | unavailable operational state | Redis is useful but should not hold required clinical answers |
+| Ped-AI to LiteLLM | provider downtime, wrong model mode | metadata-based model discovery and timeouts |
+| Ped-AI to MCP | retrieval latency/failure | explicit MCP client layer and graceful fallback messages |
+| MCP to Nextcloud | stale indexed metadata | scanner/indexer updates source metadata over time |
+
+### Source Of Truth
+
+| Data | Source Of Truth |
+|---|---|
+| User accounts and sessions | Ped-AI PostgreSQL |
+| Admin app settings | Ped-AI PostgreSQL `app_settings` |
+| Clinical source documents | Nextcloud and MCP index |
+| Clinical source title/path shown to users | MCP result metadata, especially indexed `file_path` |
+| Clinical answer text | Generated per request; intentionally not cached |
+| Model availability | LiteLLM metadata and configured fallbacks |
+
+### Deployment Shape
+
+Production usually runs:
+
+```txt
+Caddy/TLS
+ -> pediatric-ai-scribe container
+ -> pedscribe-db container
+ -> ped-ai-redis container
+ -> LiteLLM endpoint
+ -> MCP endpoint
+```
+
+The app should stay private behind the reverse proxy. Do not expose PostgreSQL, Redis, MCP internals, or provider keys publicly.
+
+### Design Principles
+
+- Keep Ped-AI stateless enough to run more than one app container.
+- Keep clinical answer generation live and source-grounded; do not cache final clinical answers.
+- Prefer model capability metadata over model-name regexes.
+- Prefer indexed file names and paths over embedded PDF metadata for source titles.
+- Keep renderer fixes narrow and tested because LLM markdown is messy.
+- Keep old frontend globals working until the affected feature is intentionally converted to ESM.

+Or run it the way production does, against the built image:
+
+```bash
+cp .env.example .env
+./scripts/build-image.sh
+docker compose up -d --no-build
+curl -fsS http://127.0.0.1:3552/api/health
+```
+
+Use Node 24 to match the image. Tests run from the repository root with
+`npm ci && npm test`; `node --check ` is a fast syntax gate when you are
+touching a backend entrypoint.
+
+## Change workflow
+
+1. Read the relevant route, utility, frontend module, and tests before editing.
+2. Make the smallest correct change.
+3. Add or update a regression test when changing clinical rendering, model routing, auth, settings, or source handling.
+4. Run focused tests first if available.
+5. Run `npm test` before deploy or commit.
+6. Deploy with Docker only after tests pass.
+7. Verify `/api/health` after deploy.
+
+## Changing the Clinical Assistant
+
+Clinical Assistant changes should usually include tests because small rendering or prompt changes can affect clinical trust.
+
+High-risk areas:
+
+- citation linking,
+- table rendering,
+- source title cleanup,
+- named-source provenance rules,
+- image intent detection,
+- MCP result normalization,
+- provider/model selection.
+
+When a real answer renders badly, save a de-identified example as a fixture or direct test input. Do not make broad global repairs that convert arbitrary numbers into citation links.
+
+## Frontend rendering rules
+
+Use `textContent` for plain text. Use `innerHTML` only for static templates, sanitized markdown, or HTML built entirely from escaped values.
+
+Safe patterns:
+
+```js
+el.textContent = userText;
+el.innerHTML = escapeHtml(userText).replace(/\n/g, '
');
+el.innerHTML = sanitizeHtml(renderMarkdown(modelOutput));
+```
+
+Unsafe pattern:
+
+```js
+el.innerHTML = modelOutput;
+```
+
+If a dynamic value enters an HTML string, escape it at the point of insertion. If it is an attribute value, escape quotes too.
+
+## Deployment checks
+
+After deployment:
+
+```bash
+curl -fsS http://127.0.0.1:3552/api/health
+docker compose ps pediatric-scribe
+```
+
+If the browser still shows old frontend behavior, force-refresh or check the injected `BUILD_ID` asset query string.
+
+## Documentation expectations
+
+Keep docs close to operational truth. If a behavior changes, update the most specific doc in the same change. Prefer short, current docs over long historical explanations.

-# Transcription Options
-
-Ped-AI currently supports server-side transcription through LiteLLM plus an explicit browser Web Speech preview option. Browser Whisper was removed and should not be offered in settings, documentation, public workers, or model download scripts.
-
-## Recommended Clinical Setup
-
-Route STT through LiteLLM and configure the compliant upstream in LiteLLM.
-
-| Need | Recommended provider |
-|---|---|
-| Server STT | LiteLLM with a compliant upstream. |
-| Real-time draft preview | Browser Web Speech only with explicit user opt-in and privacy warning. |
-
-Auto-detect uses LiteLLM when `LITELLM_API_BASE` is configured. Direct Google, AWS, local Whisper, and OpenAI Whisper branches are not part of the app runtime.
-
-## Configuration
-
-```env
-TRANSCRIBE_PROVIDER=litellm
-LITELLM_API_BASE=https://your-litellm.example/v1
-LITELLM_API_KEY=
-LITELLM_STT_MODEL=local-parakeet-v3
-```
-
-## Failure Handling
-
-- Every recording is kept, encrypted, for 24 hours — not only the ones whose
- transcription failed — and can be downloaded from Settings.
-- Users can retry or delete failed backups from Settings.
-- Web Speech interim text is not a substitute for a server transcription response.
