From 68c8478aed2a0b1b6cadfbfc53a6e430a9366aa1 Mon Sep 17 00:00:00 2001 From: Salih Yilboga Date: Mon, 3 Aug 2026 22:53:49 +0300 Subject: [PATCH 01/30] =?UTF-8?q?release:=20v1.3.0=20=E2=80=94=20ModelForg?= =?UTF-8?q?e=20Medical,=20a=20clinical=20decision-support=20workspace?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This release moves the project from a general-purpose local AI chat/agent client to a medical-focused clinical workspace. See the notice at the top of README.md and its Product boundary section for what that does and doesn't mean (never an autonomous diagnostician or prescriber, no regulatory certification claimed). Highlights: - Clinical layer: Patient Cases, Evidence Library, per-case Knowledge Graph, and an Audit & Privacy log, plus a structured 8-section response contract and deterministic safety checks (emergency red-flag detection, allergy/medication conflict warnings, transmission preview, redaction) that run independently of the model. - MCP client rework on the official SDK: protocol version negotiation, AJV schema validation, resources/prompts, OAuth 2.1+PKCE, per-tool trust profiles, and a DICOM MCP integration with an enforced tool denylist. - Privacy/security: passphrase-based encryption at rest for patient cases and chat sessions, automatic session locking, configurable audit retention, and a SHA-256 hash-chained tamper-evident audit log. - Approved model registry, clinical-note review sign-off, structured consent records, and a swappable MedicationSafetyProvider. - Rust-backed data store I/O (lib/, napi-rs): atomic JSON read/write and audit-log hashing/appends moved off the O(n) Node path, fixing an O(n^2) audit-log growth pattern (~20s -> ~0.3s at 5,000 events) — every native call has a verified pure-TypeScript fallback. See docs/RUST_DATASTORE_TEST_REPORT.md and docs/RUST_MIGRATION_ASSESSMENT.md. - SBOM generation and Dependabot coverage across every workspace; CI's Rust job now also builds and load-verifies the native addon on Windows and macOS, not just Linux.

It never presents a single diagnosis as settled fact — the response contract requires "possible interpretations," not a verdict, and every model-generated message in Clinical Assistant is labeled **"Not verified."** +- A prescriber. It does not place orders, submit prescriptions, or take any other consequential clinical action on its own. +- A certified HIPAA/HITRUST-compliant system, or any other regulatory certification. It stores data locally by default and logs an audit trail (see **Audit & Privacy** in the app), but that is a privacy *posture*, not a certification — evaluate it against your own organization's compliance requirements before using it with real patient data. + +Every clinically relevant answer is asked to follow an eight-section structure (Summary → Known patient facts → Assessment/possible interpretations → Missing information → Red flags → Suggested next steps → Evidence and citations → Uncertainty and limitations), enforced via system prompt in `frontend/src/pages/Chat.tsx` (`CLINICAL_RESPONSE_CONTRACT`). Because a system prompt is not a hard guarantee, the safety-critical checks below run independently of the model: + +- **Emergency red-flag detection** (`app/src/medical-safety.ts`, `checkForEmergencyFlags`) scans the user's own message for plain-language emergency phrasing (difficulty breathing, stroke symptoms, severe chest pain, anaphylaxis, major bleeding, loss of consciousness, active self-harm risk, overdose) *before* any model call, and shows a persistent banner telling the user to contact emergency services — this never depends on, or waits for, a model response. +- **Allergy/medication conflict warnings** (`checkMedicationConflicts`) run against a Patient Case's recorded allergies and medications using simple keyword/synonym matching — explicitly **not** a licensed drug-interaction database (First Databank, Lexicomp, Multum, etc.), and labeled as such in the UI every time a warning appears. +- **Transmission preview and consent**: sending a message to a remote provider (OpenAI/Anthropic/Gemini/a custom endpoint) while a patient case or file is attached shows exactly what's included and requires explicit confirmation before anything leaves the device. Local providers (Ollama, llama.cpp) never trigger this, since nothing leaves the device either way. +- **Untrusted-content framing**: attached files and retrieved (RAG) content are wrapped with an explicit instruction that the model must treat them as reference material, not commands — mitigating (not eliminating) prompt injection from an imported clinical document. + +## Medical MCP integrations + +Agent mode already supports arbitrary MCP servers (stdio and Streamable HTTP — see [MCP servers](#mcp-model-context-protocol-servers) below); Settings → MCP Servers now also offers one-click **quick-add presets** for verified, real MCP servers useful for medical work (`frontend/src/lib/mcp-presets.ts`): + +- **[Graphify](https://github.com/graphify-ai/graphify)** — this project's own knowledge-graph tool ships a `graphify --mcp` stdio mode (see `.claude/skills/graphify/SKILL.md`). Point it at a folder of documents, papers, or case attachments and its query/path/explain tools become available to Clinical Assistant like any other tool, gated by the same per-call approval. The Knowledge Graph page links here for anything beyond its own simple per-case field visualization. +- **[BioMCP](https://github.com/genomoncology/biomcp)** — `biomcp serve`, giving the model structured access to PubMed, ClinicalTrials.gov, and MyVariant.info. Public databases, no API key required. +- **[DICOM MCP](https://github.com/ChristianHinge/dicom-mcp)** — `uvx dicom-mcp `, giving the model connection verification (`verify_connection`) and study/series/patient/instance metadata queries against a configured DICOM node, plus signed-report text extraction (`extract_pdf_text_from_dicom`). Scoped deliberately narrower than the upstream server: `move_series` and `move_study` (DICOM C-MOVE, which transfers studies between nodes) are hard-blocked in code via `McpServerConfig.blockedTools` — filtered out of both the tool list and `callMcpTool` itself in `app/src/mcp-client.ts`, not just hidden in the UI, and never exposed to the model even if a given server offers them. The upstream project's own README states plainly that it "is not meant for clinical use, and should not be connected with live hospital databases or databases with patient-sensitive data" — ModelForge Medical surfaces that exact warning in Settings when adding the preset and on every tool-approval card for its tools, and treats the integration as a prototype accordingly. Raw image/pixel content is never forwarded into a model's context by any MCP tool call, DICOM or otherwise — see the "no autonomous interpretation of image pixels" note in `mcp-client.ts`'s `buildStructuredResult`. + +All three require their own CLI installed first (`pip install graphifyy`, `uv tool install biomcp-cli`, `uv tool install dicom-mcp` respectively) — the quick-add button prefills the command into the existing manual "Add MCP server" form so you can review (and fill in any ``, e.g. a folder path or config file) before connecting; it never installs or runs anything without that explicit step. + +A few other real, healthcare-relevant MCP servers exist but weren't added as one-click presets because they need more than a command line to actually work — e.g. the [FHIR MCP Server](https://github.com/the-momentum/fhir-mcp-server) requires a Docker build plus a `.env` file with FHIR server and Pinecone credentials. Advanced users can still add these manually via Settings → MCP Servers using their own documented setup; adding them as a "quick add" button would have implied a one-click experience they don't actually have. + +### MCP client — spec-correctness and security rework + +Before adding the DICOM MCP preset, the MCP client itself (`app/src/mcp-client.ts`) was rebuilt from a hand-rolled JSON-RPC implementation to the official `@modelcontextprotocol/sdk`, closing several real gaps: + +- **Protocol version negotiation** — the SDK negotiates against `LATEST_PROTOCOL_VERSION` and rejects an unsupported server version, instead of blindly sending a hardcoded `"2024-11-05"` and never checking the response. +- **Real JSON Schema validation** (`app/src/mcp-schema-validation.ts`, AJV) — replaces a shallow required/type-only check with full `$ref`/`oneOf`/`pattern`/`enum`/nested-schema support, compiled and cached per server+tool at connect time. +- **Resources, resource templates, and prompts** — `listResources`/`listResourceTemplates`/`readResource`/`listPrompts`/`getPrompt`, previously unsupported entirely. +- **Structured tool results** — `structuredContent`, MIME types, and resource links are preserved instead of being flattened into a lossy string (`callMcpToolStructured`). +- **Server trust profiles** — a per-tool-name allowlist a user builds one tool at a time in Settings for a specific connected server, never a blanket "trust this server" toggle; every other tool call still requires per-call approval. +- **Progress and cancellation** — long-running tool calls can report progress (shown as a progress bar on the approval card) and be cancelled mid-call. +- **OAuth 2.1 + PKCE** (`app/src/mcp-oauth.ts`) for HTTP-transport servers — authorization-server discovery, dynamic client registration, and RFC 8707 resource-indicator scoping (so a token obtained for one server is never usable against another) via the SDK's built-in `OAuthClientProvider`; tokens are stored through the existing `safeStorage`-backed secrets store, namespaced per server. +- **PHI transmission preview** before any tool call to an http-transport (remote) MCP server, showing exactly what's about to be sent and to which server. +- **Audit trail extensions** — every MCP tool call (approved, auto-approved, or denied) is logged with server identity, tool name, approval outcome, duration, and the currently-attached patient case — but never the call's actual arguments or result, which can carry PHI. +- **Untrusted tool descriptions** — the approval card now shows which MCP server a tool call came from and renders the server's own tool description in a clearly labeled "server-provided, unverified" block, rather than treating it as trusted UI text. + +## Limitations and what still needs external authority + +The items below are **not solved by this codebase alone** — they require licensed data, legal review, or clinical validation that no amount of code can substitute for: + +- **Drug-interaction and allergy checking** uses a small demonstration list (`KNOWN_INTERACTIONS` in `app/src/medical-safety.ts`), not a licensed clinical database. Do not treat its absence of a warning as clearance. +- **Evidence Library and Knowledge Graph** are honest about what they are: Evidence Library only records a page's own ``/meta description when you add a URL (never a fabricated citation); Knowledge Graph only visualizes structured fields already on a case (conditions/allergies/medications), with no medical ontology (UMLS/SNOMED/RxNorm) linkage and no inferred relationships. +- **No clinician identity/authentication system** — `enteredBy`/audit actor fields are plain text, not a verified identity. Session locking (below) narrows *when* case data is accessible, but not *by whom* — anyone with the passphrase (or the unlocked, running app) has full access. +- **No regulatory certification of any kind.** HIPAA/HITRUST/FDA claims would require legal and compliance review this change cannot perform. Encryption at rest and session locking (below) are real privacy controls, not compliance certifications. +- **Accessibility** follows the existing app's ad hoc `aria-*` labeling; a full WCAG 2.2 AA audit (automated tooling, screen-reader testing, keyboard-only pass across every new page) has not been performed. +- **No literature-search API integration** (e.g. PubMed) — Evidence Library is add-by-URL only, deliberately, to avoid presenting unreviewed live search results as vetted medical evidence. +- **PHI redaction before a remote send** (Clinical Assistant's "Redact identifiers before sending" checkbox, `medical-safety.ts`'s `redactIdentifiers`) is the same best-effort, pattern-based scrubbing described above for drug interactions — it catches emails/phones/SSNs/MRNs/dates via regex, not clinical-grade de-identification (HIPAA Safe Harbor requires far more: names, locations, ages 90+, device identifiers, etc. embedded in free-text narrative). Off by default; opt in per the risk you're willing to accept, and never treat a "0 redacted" result as confirmation the text was actually clean. + +### Privacy/security controls that *are* implemented + +Beyond the transmission preview and audit trail described earlier, this session added: + +- **Encryption at rest for patient case data** (`app/src/case-encryption.ts`, Settings → Audit & Privacy) — optional, passphrase-based AES-256-GCM encryption of `patient-cases.json`. The passphrase itself is never written to disk in any form (only a salt and an HMAC verifier); the derived key lives in memory only for the current unlocked session. This protects the file at rest (a stolen/copied device, a backup, a synced folder) — it does not protect against anyone with access to the running, unlocked app, which is what session locking narrows. +- **Automatic session locking** — a configurable inactivity timeout (Settings → Audit & Privacy, default 15 minutes, disable-able) that re-locks case encryption after no keyboard/mouse activity; Patient Cases shows a passphrase prompt in place of case content until unlocked again. Still device-login-level security if encryption itself is off — there is no separate app-wide lock independent of case encryption. +- **Configurable audit log retention** — Settings → Audit & Privacy lets you cap how long audit events are kept (30/90/365 days, or forever), purged on both read and write, on top of the existing fixed 5,000-event cap. +- **Tamper-evident audit log** — every audit event is now SHA-256 hash-chained to the one before it (`app/src/audit-log-store.ts`); Settings → Audit & Privacy's "Verify integrity" button recomputes the chain and reports whether any event was edited, reordered, or deleted after the fact. +- **Encryption at rest also covers chat sessions**, not just patient cases — `sessions.json` shares the exact same passphrase and encryption gate as `patient-cases.json`, since chat messages routinely carry the same clinical detail typed or pasted into a message. +- **Structured consent records and clinical-note review sign-off** on a case (Patient Cases → a case → Consent / Clinical notes) — consent grants/revocations with scope and method, and a reviewedBy/outcome sign-off gate specifically for model-generated notes, so "present in the case" is never conflated with "a clinician reviewed it." +- **Approved model registry** (Settings → Audit & Privacy → Approved model registry) — optionally restrict Clinical Assistant to an explicit allowlist of provider/model pairs; enforced in `Chat.tsx`'s send path, not just hidden from a picker. +- **SBOM generation and dependency update automation** — CI (`.github/workflows/ci.yml`, `sbom` job) generates a CycloneDX SBOM for every npm workspace on each run; `.github/dependabot.yml` covers all five npm workspaces, the Rust download engine (`lib/`), the Python hardware-recommender project, and the workflows' own GitHub Actions. +- **Rust-backed data store I/O** — `lib/` (the same napi-rs addon used for GGUF downloads) now also backs the read/write/hash path every `*-store.ts` sits on: atomic JSON file reads and writes (`lib/src/datastore.rs`), and the SHA-256 hashing behind the audit log's tamper-evident chain. Every store falls back to pure Node/TypeScript automatically when the addon hasn't been built (`app/src/native-datastore.ts`) — dev, test, and E2E runs are unaffected; only a packaged build (`npm run build:native`) gets the faster path. +- **O(1) audit log appends** — the audit log used to do a full read-parse-stringify-write of its entire (only-ever-growing) event array on every single recorded event, an O(n²) pattern that made 5,000 sequential writes take ~20+ seconds. `append_json_array_element` (`lib/src/datastore.rs`) now splices a new event directly onto the end of the existing file — no re-reading, re-parsing, or re-serializing what's already there — backed by an mtime/size-checkpointed in-memory cache (`audit-log-store.ts`) that's always verified against the real file before use and never substituted for a real read when verifying the tamper-evident hash chain or listing events. Same 5,000-write benchmark: ~300ms with the native addon built, unchanged (~20s) without it — this optimization only ever narrows, never changes, correctness or on-disk format. Falls back to the original full-rewrite path automatically whenever age-based retention is active (it needs to see every event to purge by age) or the event count is at/over the 5,000 cap (needs the whole array to trim). + +None of these are substitutes for encrypting the whole device, a real identity/access-control system, or a compliance audit — they narrow specific, real gaps without claiming to close the larger ones. + ## Contents - [Features](#features) @@ -195,7 +268,10 @@ This README covers what the app does and how to install/build it.

It is deliberately **not**: + +- An autonomous diagnostician — every clinically relevant answer is structured as + "possible interpretations," never a single settled diagnosis, and every + model-generated message carries a **"Not verified"** badge (`frontend/src/pages/Chat.tsx`, + the `MessageBubble` component). +- A prescriber — the app places no orders and submits nothing on a clinician's + behalf; every tool call (built-in or MCP) still requires per-call human approval. + See [Agent mode](AGENT_MODE.md) for that approval model in full. +- A certified HIPAA/HITRUST/FDA-compliant system. Local-first storage, an audit + trail, encryption at rest, and session locking are real privacy *controls* — + none of them are a compliance *certification*. See [Known limitations](#known-limitations). + +## Navigation map + +The sidebar's **Clinical** group (`frontend/src/components/layout.tsx`) adds four +routes on top of the base app's Chat/Settings/Compare/etc.: + +| Route | Page | Purpose | +|---|---|---| +| `/cases` | `pages/PatientCases.tsx` | List, create, delete patient cases | +| `/cases/:caseId` | `pages/PatientCaseDetail.tsx` | Structured case fields, per-field context selection, conflict warnings | +| `/evidence` | `pages/EvidenceLibrary.tsx` | Add-by-URL evidence source library | +| `/knowledge-graph` | `pages/KnowledgeGraph.tsx` | Per-case concept graph (conditions/allergies/medications) | +| `/audit` | `pages/AuditPrivacy.tsx` | Audit trail, encryption management, session-lock settings, retention | + +Clinical Assistant itself is the existing `/` and `/chat/:sessionId` routes +(`pages/Chat.tsx`) — it wasn't given a new route, only a safety layer layered on top +(below). + +## Clinical Assistant + +### Structured response contract + +Every message sent from Clinical Assistant carries a system-prompt addendum, +`CLINICAL_RESPONSE_CONTRACT` (`frontend/src/pages/Chat.tsx`), requiring exactly +eight sections in order whenever the answer is clinically relevant: + +1. Summary +2. Known patient facts +3. Assessment or possible interpretations +4. Missing information +5. Red flags and urgent concerns +6. Suggested next clinical steps +7. Evidence and citations +8. Uncertainty and limitations + +This is a *prompt*, not a guarantee — a model can still fail to follow it. That's +why the safety-critical pieces below (emergency detection, drug-conflict warnings) +run as plain code, independent of anything the model says. + +### Clinical modes + +A dropdown in the composer toolbar (`CLINICAL_MODES` in `Chat.tsx`) prepends a +mode-specific instruction on top of the response contract: + +| Key | Label | Instruction focus | +|---|---|---| +| `none` | General | No addition (default) | +| `soap` | SOAP note | Subjective/Objective/Assessment/Plan | +| `differential` | Differential diagnosis support | Ranked possible interpretations, not a single diagnosis | +| `medicationReview` | Medication review | Interactions, duplication, dosing concerns | +| `dischargeSummary` | Discharge summary | — | +| `patientEducation` | Patient education | Plain-language, no unexplained jargon | +| `researchReview` | Research/literature review | Summarize literature/guidelines, cite sources | + +### Emergency red-flag detection + +`app/src/medical-safety.ts`'s `checkForEmergencyFlags(text)` scans the **user's own +message** — before any model call — for plain-language emergency phrasing: +difficulty breathing, stroke symptoms (facial droop, slurred speech, sudden +weakness/numbness), severe chest pain, anaphylaxis, major bleeding, loss of +consciousness, active self-harm risk, overdose. A match sets `emergencyFlags` state +in `Chat.tsx`, rendering a persistent, dismissible banner +(`EMERGENCY_BANNER_TEXT`) telling the user to contact emergency services — this +banner's appearance **never depends on, or waits for, a model response**; it's +computed and shown before the message is even sent to a model. Reached via +IPC `medicalSafety:checkEmergency` (deterministic regex matching, no model call — +see [`medical-safety.test.ts`](../app/src/medical-safety.test.ts) for the exact +pattern list and what does/doesn't trigger it). + +### Allergy / medication conflict warnings + +`checkMedicationConflicts(allergies, medications)` in the same file runs +deterministic keyword/synonym matching against a Patient Case's recorded allergies +and medications: + +- **Allergy matches**: a small synonym table (`ALLERGY_CLASS_SYNONYMS`) maps common + allergy classes (penicillin, sulfa, NSAID) to their member drug names. +- **Known interaction pairs**: a small demonstration list (`KNOWN_INTERACTIONS`, + e.g. warfarin+aspirin, MAOI+SSRI, sildenafil+nitrate) — explicitly **not** a + licensed clinical drug-interaction database (First Databank, Lexicomp, Multum). + +Every warning rendered from this (`PatientCaseDetail.tsx`) is labeled "Generated by +simple keyword matching, not a licensed drug-interaction database. Verify +independently." Reached via IPC `patientCases:checkConflicts`. + +### Transmission preview before a remote send + +Sending to a remote provider (anything not in `LOCAL_PROVIDERS` — i.e. not Ollama, +llama.cpp, or a local MLX/ROCm/vLLM runtime) while a patient case is attached or +files are attached triggers a native `confirm()` dialog listing exactly what's +about to leave the device and to which provider, **before** the request fires +(`handleSend` in `Chat.tsx`). Declining aborts the send entirely — nothing is sent +silently. + +### PHI redaction (opt-in) + +A checkbox in the composer ("Redact identifiers before sending"), shown only when +the selected model is a remote provider, runs `medicalSafety.redact(content)` +(`redactIdentifiers` — regex patterns for email, phone, SSN, MRN, DOB) on the fully +assembled outgoing content **before** the transmission-preview dialog, so the +confirmation the user sees already reflects the redacted text and the redaction +count. Off by default — this is pattern-based scrubbing, not clinical-grade +de-identification (HIPAA Safe Harbor requires far more: free-text narrative +mentions of names, locations, rare ages, device identifiers, etc., none of which +regex can reliably catch). + +### Untrusted-content framing + +Attached files and RAG-retrieved content are wrapped with an explicit +`UNTRUSTED_CONTENT_PREAMBLE` (`Chat.tsx`, `buildMessageContent`) telling the model +this is reference material to inform its answer, never an instruction to follow — +a mitigation (not an elimination) of prompt injection via an imported clinical +document. Patient-case field content is **not** wrapped this way, since it's +clinician-typed, trusted input, not imported/untrusted content. + +### Case attachment and context selection + +A dropdown in the composer lets the user attach one Patient Case to the current +message. Only the fields the user has explicitly marked `includeInContext: true` +on that case (see [Patient Cases](#patient-cases)) are pulled in — via +`patientCases:buildContext` — and prefixed as `Patient case context +(clinician-entered, fields explicitly included by the user):` ahead of the user's +own message text. + +## Patient Cases + +`app/src/patient-cases-store.ts` + `app/src/schemas.ts` (`patientCaseSchema`). + +### Structured fields + +Every clinical field on a `PatientCase` is a `CaseField<T> = { value: T; +includeInContext: boolean }` — the `includeInContext` flag is what the "user +controls exactly which fields are sent" requirement is actually built on; nothing +is included in a model prompt unless that flag is explicitly `true`, and it +defaults to `false` on every new case and every new field. + +| Field | Type | Notes | +|---|---|---| +| `demographics` | `CaseField<{age?, sex?, notes?}>` | | +| `presentingComplaint` | `CaseField<string>` | | +| `symptomsTimeline` | `CaseField<string>` | | +| `vitalSigns` | `CaseField<string>` | Free text, e.g. `"BP 122/78, HR 76, RR 16, Temp 37.0°C, SpO2 98%"` | +| `conditions` | `CaseField<string[]>` | | +| `allergies` | `CaseField<string[]>` | Feeds the conflict checker | +| `medications` | `CaseField<string[]>` | Feeds the conflict checker | +| `labResults` | `CaseField<LabResult[]>` | `{id, name, value, unit?, referenceRange?, observedAt?}` | +| `imagingAndReports` | `CaseField<string>` | | +| `clinicalNotes` | `ClinicalNote[]` | `{id, author: "clinician" \| "model-inference", text, createdAt}` — provenance-tagged, never blended | +| `attachments` | `AttachmentRef[]` | `{id, name, mimeType?, addedAt}` | +| `consentNote`, `enteredBy` | `string?` | Plain text — no verified-identity system behind `enteredBy` (see [Known limitations](#known-limitations)) | + +### Case isolation + +Every read goes through `getCase(id)` / `listCases()`, which never does a raw array +index or unfiltered scan — a caller can only ever get back the one case it asked +for. This is the actual guarantee behind "one patient's data never leaks into +another case's context." See `patient-cases-store.test.ts`'s "isolates cases from +one another" test. + +### `buildContextForCase` + +The single choke point that assembles a model-prompt-ready text block: iterates +every field, includes a line only if `includeInContext` is true and the field is +non-empty, and returns both the text and the list of included field labels (so the +transmission preview can show exactly what was included in plain language, not +just a raw diff). + +## Evidence Library + +`app/src/evidence-store.ts` + `app/src/schemas.ts` (`evidenceSourceSchema`). + +Add-by-URL only — deliberately, to avoid presenting unreviewed live search results +as vetted medical evidence. `addSourceFromUrl(url)`: + +1. Validates the URL is `http(s)://` (rejects anything else, e.g. `file://`). +2. Fetches the page (15s timeout) and extracts only what it can honestly find: the + `<title>` tag and a `<meta name="description">` tag. **Never fabricates** a + title, author, or date it couldn't find — a missing title falls back to the + URL's path, never an invented string. +3. Guesses `organization` and `sourceType` (`peer-reviewed` / `guideline` / + `reference-database` / `other`) from a small table of known domains + (`KNOWN_ORGANIZATIONS`: PubMed/NCBI, NIH, WHO, CDC, FDA, Cochrane, UpToDate) — + this is a UI convenience default, not a claim that every page on that domain is + peer-reviewed. + +Sources added here are what `checkCitations` (`medical-safety.ts`) can cross-check +a model's inline citation markers (`[1]`, `(Smith, 2020)`) against — a marker with +no matching known source is flagged as unverified rather than trusted at face +value. (This citation-checking function exists and is tested; it is not yet wired +into Clinical Assistant's message rendering — see [Known limitations](#known-limitations).) + +## Knowledge Graph + +`frontend/src/pages/KnowledgeGraph.tsx` — intentionally simple and honest about +what it is: a **per-case concept graph**, not a medical knowledge base. Nodes are +built directly from a case's `conditions` / `allergies` / `medications` fields +(rendered via the existing Mermaid diagram support), with every node's provenance +listed in a table below the diagram (which case field it came from). No +UMLS/SNOMED/RxNorm linkage, no inferred relationships — it shows only what's +directly on the case. + +For anything richer (building a real knowledge graph from a folder of documents, +papers, or imaging reports, and letting Clinical Assistant query/path/explain it), +the page links to connecting **Graphify** as an MCP server — see +[Medical MCP integrations](#medical-mcp-integrations). + +## Audit & Privacy + +`app/src/audit-log-store.ts` + `app/src/schemas.ts` (`auditEventSchema`), +UI at `frontend/src/pages/AuditPrivacy.tsx`. + +### What's logged + +Every `AuditEvent` has `id`, `timestamp`, `actionCategory`, and optional +`targetType` / `targetId` / `detail`. The categories: + +| Category | Recorded when | +|---|---| +| `case-created` / `case-updated` / `case-deleted` / `case-viewed` | Patient Cases CRUD (`patient-cases-handlers.ts`) | +| `model-call-local` / `model-call-remote` | Every chat send, split by whether the provider is local or remote | +| `mcp-tool-call` | Every MCP tool call — approved, auto-approved, or denied (see below) | +| `export` / `data-deleted` / `settings-changed` | Data export, deletions, and settings changes such as enabling encryption | + +`mcp-tool-call` events additionally carry `mcpServerId`, `mcpServerName`, +`mcpToolName`, `approvalOutcome` (`"approved" | "auto-approved" | "denied"`), and +`durationMs` — recorded from `Chat.tsx`'s `respondToToolCall`, which measures wall +time around the tool execution and calls `window.api.audit.record(...)` regardless +of whether the call was approved, auto-approved (via a trust profile — see +[MCP client architecture](#mcp-client-architecture)), or denied. + +### What's deliberately never logged + +**No field on `AuditEvent` carries a tool call's actual arguments or result.** +`detail` is documented as "short, non-clinical" and callers are responsible for +keeping it that way — the store itself doesn't (and structurally can't) inspect it +for clinical content, but nothing in the codebase puts clinical narrative into it. +This is a deliberate design constraint: the audit trail's whole purpose is +accountability (who did what, when, was it approved), and turning it into a second +place PHI could leak from would defeat that purpose. + +### Retention + +Settings → Audit & Privacy offers **30 days / 90 days / 1 year / forever** +(`AppSettings.auditLogRetentionDays`). Purging happens both on write (`recordEvent`) +and on read (`listEvents`), so lowering the retention window takes effect +immediately rather than waiting for the next recorded event. This sits on top of a +fixed `MAX_EVENTS = 5000` hard cap that always applies regardless of the +age-based setting. + +## Encryption at rest + +`app/src/case-encryption.ts`, IPC in `app/src/ipc/encryption-handlers.ts`, UI in +`AuditPrivacy.tsx`'s `EncryptionSection`. + +### Threat model + +Protects `patient-cases.json` (the one store holding real clinical detail — +allergies, medications, conditions, notes) against **someone with filesystem +access but not the passphrase**: a stolen laptop that's powered off, a backup tool, +a synced folder. It does **not** protect against an attacker with control of the +running, unlocked app — that's narrowed by [session locking](#automatic-session-locking), +not eliminated by it. + +### How it works + +- **AES-256-GCM**, key derived from a user passphrase via `crypto.scryptSync` + with a random 16-byte salt. +- The **passphrase itself is never stored anywhere, in any form.** Only the salt + (safe to store — its job is defeating rainbow tables, not being secret) and a + **verifier** — an HMAC of a fixed message, computed with the derived key — + persist to `case-encryption-config.json`. A passphrase check is "derive the key, + recompute the HMAC, compare to the stored verifier" — the passphrase is compared + to nothing; only its *derived key's fingerprint* is. +- The derived key lives **only in main-process memory**, only while the session + considers itself unlocked. Nothing persists it across an app restart — every + fresh launch starts locked if encryption is enabled. +- **Two physical files**, never both authoritative at once: `patient-cases.json` + (plaintext) and `patient-cases.enc.json` (an envelope of `{ivHex, + ciphertextHex, authTagHex}`). Switching modes always deletes the now-stale file + — enabling encryption deletes the plaintext copy after the encrypted one is + written; disabling does the reverse. Stale plaintext is never left lying around + next to a freshly-encrypted copy, or vice versa. + +### Flows (all in `encryption-handlers.ts`, orchestrating `case-encryption.ts` + `patient-cases-store.ts`) + +| Action | What happens | +|---|---| +| **Setup** | Read existing (plaintext) cases → `caseEncryption.setup(passphrase)` (new salt/key/verifier, unlocks) → re-write cases (now encrypted) → audit `settings-changed` | +| **Unlock** | Derive key from stored salt, compare verifier — no state change to case files | +| **Lock** | Clear the in-memory key only — case files untouched, unreadable again until unlock | +| **Disable** | Verify passphrase (which also unlocks) → read cases (decrypts with current key) → clear encryption config → re-write cases (now plaintext) → audit | +| **Change passphrase** | Verify old passphrase → read cases (decrypts with *old* key) → rotate to new salt/key/verifier → re-write cases (encrypts with *new* key) → audit | + +Reading (`readAll`) or writing (`writeAll`) case data while encryption is enabled +but locked throws `CaseDataLockedError` rather than silently returning an empty +list — an empty case list and "you haven't unlocked it" must never look the same +to a caller. `PatientCases.tsx` / `PatientCaseDetail.tsx` check `encryption:status` +before listing/loading and render a `<CaseLockScreen>` passphrase prompt instead of +case content whenever locked. + +## Automatic session locking + +`frontend/src/lib/use-case-auto-lock.ts` (DOM/timer wiring, mounted once in +`layout.tsx`) + `frontend/src/lib/case-auto-lock.ts` (pure decision logic, +unit-tested separately from the timer wiring). + +- Configurable timeout in Settings → Audit & Privacy: Never / 5 / 15 (default) / + 30 / 60 minutes (`AppSettings.caseAutoLockMinutes`). +- Implemented as **polling against wall-clock time since last activity** (checked + every 30s) rather than one long `setTimeout`, specifically because a laptop + sleep/wake cycle doesn't reliably advance a suspended `setTimeout` delay across + platforms — polling against `Date.now()` is self-correcting regardless of + suspend/resume. +- Listens for `mousemove` / `mousedown` / `keydown` / `touchstart` / `scroll` / + `wheel` to reset the "last activity" timestamp. +- A no-op whenever encryption isn't enabled (nothing to poll for) — re-checks its + config whenever a custom `modelforge:encryption-status-changed` event fires + (dispatched by `AuditPrivacy.tsx` after any encryption-state-changing action), + so turning encryption on mid-session arms the timer without requiring an app + restart. +- On firing: calls `encryption:lock`, then dispatches `modelforge:case-locked` — + `PatientCases.tsx` / `PatientCaseDetail.tsx` listen for this and immediately + swap to the lock screen if the user is already on one of those pages when + auto-lock fires, rather than only discovering it on next navigation. + +This locks **case data specifically**, not the whole application — chat history, +Settings, and every other page remain reachable. There is no separate whole-app +lock independent of case encryption; see [Known limitations](#known-limitations). + +## Medical MCP integrations + +Settings → MCP Servers offers one-click **quick-add presets** +(`frontend/src/lib/mcp-presets.ts`) for three MCP servers, each verified against +its own upstream documentation before being hardcoded — none of the command +strings or tool names below are guessed. + +| Preset | Command | What it gives the model | +|---|---|---| +| **[Graphify](https://github.com/graphify-ai/graphify)** | `graphify <path-to-folder> --mcp` | query/path/explain over a folder of documents/papers/case attachments — this project's own knowledge-graph tool, confirmed via `.claude/skills/graphify/SKILL.md`'s documented `--mcp` flag | +| **[BioMCP](https://github.com/genomoncology/biomcp)** | `biomcp serve` | PubMed, ClinicalTrials.gov, MyVariant.info — public databases, no API key | +| **[DICOM MCP](https://github.com/ChristianHinge/dicom-mcp)** | `uvx dicom-mcp <path-to-config.yaml>` | Connection verification, study/series/patient/instance metadata queries, report-text extraction — scoped, see below | + +All three require their own CLI installed first — the quick-add button only +*prefills* the command into the existing manual "Add MCP server" form (filling in +any `<placeholder>`, e.g. a folder path, is left to the user); it never installs or +connects anything without an explicit review-and-click step. + +### DICOM MCP scoping + +The upstream `dicom-mcp` server's own tool catalog includes `move_series` and +`move_study` (DICOM C-MOVE — transfers studies between nodes). ModelForge Medical +hard-blocks both via `McpServerConfig.blockedTools`, enforced in **two places**: + +1. `filterBlockedTools()` (`app/src/mcp-client.ts`) removes any blocked tool name + from the connection's tool list at connect time, before it's ever returned by + `getConnectedTools()` — so a blocked tool never reaches the model's tool + catalog or the approval card in the first place. Filtering is logged + (`logger.warn`) rather than silent, since a server offering a blocked name (or, + on reconnect, a *new* move-shaped tool) is exactly the "don't blindly trust the + server's self-reported tool list" case this exists for. +2. `callMcpToolStructured()` independently re-checks `conn.config.blockedTools` + before dispatching *any* call — defense in depth, not just "hidden from the + list." + +Both layers are exercised in `mcp-client.test.ts`'s `blockedTools` describe block +against a real (stub) MCP server that actually offers a `move_series` tool. + +The upstream project's own README states plainly: *"DICOM-MCP is not meant for +clinical use, and should not be connected with live hospital databases or +databases with patient-sensitive data. Doing so could lead to both loss of patient +data, and leakage of patient data onto the internet."* This exact text is carried +as `warningBanner` on the preset, and surfaced in **two places**: in Settings when +adding the preset, and — via the same field, threaded through +`Chat.tsx`'s `mcpServerInfoForCall` — on every tool-approval card for any of this +server's tools, so the warning is unavoidable at the point a tool call is actually +about to run, not just once at setup. + +### No image pixel data reaches a model + +`buildStructuredResult()` (`mcp-client.ts`) is the single place every MCP tool +result passes through before becoming the text a model sees. An `image` or +`audio` content block is **only ever summarized as `[image content, image/png]`** +— its raw base64 `data` is never copied into the text output. This is enforced +generically (for any MCP server, not DICOM-specific code) and locked in by +`mcp-client.test.ts`'s "never forwards raw image content data" test, which asserts +a real base64 payload from a stub tool never appears in the structured result's +`.text`. + +## MCP client architecture + +Before adding DICOM MCP, the entire MCP client (`app/src/mcp-client.ts`) was +rebuilt from a hand-rolled JSON-RPC implementation onto the official +`@modelcontextprotocol/sdk`. This section is the detailed reference for that +rework; each piece below is independently unit-tested (see +[Testing this layer](#testing-this-layer)). + +| Concern | Where | What it does | +|---|---|---| +| **Transport** | `mcp-client.ts` — `Client` + `StdioClientTransport` / `StreamableHTTPClientTransport` | Official SDK, both transports. Protocol version negotiation happens inside the SDK's own `connect()` (validates the server's returned version against `SUPPORTED_PROTOCOL_VERSIONS`, throws on mismatch) rather than a hardcoded, unchecked version string. | +| **Schema validation** | `mcp-schema-validation.ts` | AJV, compiled and cached per server+tool at connect time. Full JSON Schema support (`$ref`/`oneOf`/`pattern`/`enum`/nested schemas) — the previous implementation only checked top-level `required`/`type`. An uncompilable schema is treated as "no validator" (permissive) rather than crashing the connection. | +| **Resources / prompts** | `mcp-client.ts` — `listResources`, `listResourceTemplates`, `readResource`, `listPrompts`, `getPrompt` | Thin wrappers over the SDK client. Not yet wired into any model-facing tool — backend plumbing only (see [Known limitations](#known-limitations)). | +| **Structured results** | `mcp-client.ts` — `callMcpToolStructured` / `buildStructuredResult` | Preserves `structuredContent`, MIME types, and resource links instead of flattening everything to a lossy string. `callMcpTool` (the model-facing entry point) still returns plain text for backward compatibility — the structured version is for audit logging and future UI. | +| **Trust profiles** | `McpServerConfig.trustProfile.autoApprovedTools`, `frontend/src/lib/tool-approval.ts`'s `trustedMcpToolNames` | Per-tool-name allowlist a user builds one tool at a time in Settings — **never** a blanket "trust this server" flag. `Chat.tsx` seeds the session's `autoApprovedTools` set with the flattened list on load, so a trusted MCP tool auto-resolves exactly like an already-approved built-in tool. | +| **Progress / cancellation** | `mcp-client.ts`'s `McpToolCallOptions` (`signal`, `onProgress`); `app-state.ts`'s `activeMcpToolRequests` map; IPC `mcp:cancelTool`; `preload.ts`'s `agent.executeToolWithProgress` | A progress bar + Cancel button render on the approval card only for an *executing* MCP tool call (built-in tools have no server-side progress support, so they're unaffected). Cancellation turns into the SDK's `notifications/cancelled`, not just a client-side give-up. | +| **OAuth 2.1 + PKCE** | `mcp-oauth.ts` | Implements the SDK's `OAuthClientProvider` interface — the SDK itself does PKCE generation, RFC 9728/8414 discovery, and RFC 8707 resource-indicator scoping (so a token obtained for one server is never reusable against another); this module only supplies storage (via the existing `secrets-store.ts`, namespaced per server) and the browser/redirect plumbing (a loopback HTTP listener on `127.0.0.1:51823`, opened only while a flow is in progress). | +| **PHI transmission preview (MCP)** | `Chat.tsx`'s `ToolApprovalCard` rendering, gated on `mcpServerInfoForCall(call)?.transport === "http"` | Same pattern as the model-call transmission preview — shown only for http-transport (remote) MCP servers, since a stdio server is a local child process. | +| **Audit + case binding** | `AuditEvent`'s `mcpServerId`/`mcpServerName`/`mcpToolName`/`approvalOutcome`/`durationMs` fields; `Chat.tsx`'s `respondToToolCall` | Every MCP tool call — approved, auto-approved, or denied — is audited with the currently-attached patient case as `targetId`, never the call's actual arguments/result. | +| **Untrusted descriptions** | `ToolApprovalCard`'s `mcpServerInfo` block | Renders the server's own tool description in a visibly separate "server-provided, unverified" block, alongside `readOnlyHint`/`destructiveHint` annotations if the server declared them — never treated as trusted UI text or as an instruction. | + +## Data model reference + +Full Zod schemas live in `app/src/schemas.ts`; TypeScript interfaces are mirrored +in `frontend/src/types/electron.d.ts` for the renderer (main-process types in +`app/src/*.ts` are the source of truth).

Evidence-backed gap analysis (by requested capability area) + +### 2.1 Identity and access management — **absent entirely** + +No login screen, no user object, no session concept beyond "the OS user who launched +the app." Confirmed by direct inspection: no SSO/OIDC/SAML/MFA library in either +`app/package.json` or `frontend/package.json`; no `User`/`Session` type in +`app/src/**`; `secrets-store.ts` and `case-encryption.ts` are per-device, not +per-person. Break-glass, RBAC/ABAC, patient/department-level authorization, and +account lifecycle management all require an identity system that doesn't exist as a +prerequisite — none of these can be partially retrofitted onto a single-user desktop +process without that foundation. **[SW+CFG]**: an identity layer is buildable, but a +desktop Electron app enforcing RBAC against a local install is inherently weaker than +a server-mediated one (a user with disk access can inspect/modify local state) — real +RBAC for this product shape implies a **server-mediated deployment topology** (see +§5 Target architecture), not just a login screen bolted onto the current +single-process app. + +### 2.2 Central institutional administration — **absent entirely** + +`app/src/settings-store.ts`'s `AppSettings` is a single flat, per-device JSON file +(`settings-store.ts:1-225`, confirmed no `organization`/`centralPolicy`/`orgPolicy` +field via grep). There is no concept of an admin pushing policy to a fleet of +installs, no remote configuration, no remote revocation, and no organization-wide +feature toggle. Agent mode can be disabled per-device by the device's own user +(Settings toggle exists for `networkToolsEnabled`, `verificationEnabled`, etc.) but +**not by an administrator remotely** — anyone with the app installed can re-enable +anything on their own machine. **[SW+CFG]**: requires a central policy service (or +at minimum, a signed policy file distribution mechanism) — pure client-side +enforcement without server backing is fundamentally circumventable by whoever has +local admin rights on the device. + +### 2.3 PHI and sensitive-data protection — **partial, one store only** + +**PHI-bearing stores identified by inspection:** + +| Store | File | PHI risk | Encryption today | +|---|---|---|---| +| Patient cases | `patient-cases.json` / `.enc.json` | High — allergies, meds, conditions, notes | **Yes**, opt-in AES-256-GCM (`case-encryption.ts`) | +| Chat sessions | `sessions-store.ts` → `sessions.json` | High — case context gets pasted/typed directly into chat messages, model responses | **No** | +| Evidence sources | `evidence-store.ts` → `evidence-sources.json` | Low (URLs/metadata only, no patient data by design) | No (not needed) | +| Audit log | `audit-log-store.ts` → `audit-log.json` | Low by design (`detail` documented as non-clinical, never enforced at the type level) | No | +| RAG embeddings | `app/src/rag.ts` (per `docs/ARCHITECTURE.md`) | High if a clinical document is embedded | **Not inspected in this pass — flag for follow-up; likely unencrypted like sessions.** | +| Exported files | `data-transfer.ts`-driven exports (session/all export) | High | **No** — exports are plaintext by construction | +| Electron cache/temp | Chromium's own disk cache, crash dumps | Unknown/high | **Not addressed at all** — outside this app's direct control without Electron-level hardening | +| Logs | `logger.ts` rotating file logs | Medium — depends on what gets logged; not audited for PHI leakage in this pass | **Not addressed** | +| Backups | None exist — no backup mechanism at all currently | N/A | N/A | + +**This is the single largest concrete gap**: chat session history — where actual +clinical conversation content lives, arguably the *highest*-PHI-density store in the +app — has **no encryption at rest**, while only the structured Patient Case store +does. A user could enable case encryption, feel protected, and still have full +clinical detail sitting in plaintext `sessions.json` from every conversation. +**[SW]** extending `case-encryption.ts`'s pattern to sessions is directly buildable; +**[SW]** a temp-file/cache audit is buildable; **[CFG]** enterprise key +management (HSM/KMS-backed keys, rotation) requires infrastructure this app doesn't +have and a passphrase-only design (as built) cannot satisfy on its own; **[LEGAL]** +BAA/DPA and zero-retention configuration metadata are provider contracts, not code. + +De-identification: `medical-safety.ts`'s `redactIdentifiers` is regex-only +(email/phone/SSN/MRN/DOB patterns — `medical-safety.ts`, confirmed via +`docs/CLINICAL_WORKSPACE.md`'s own explicit caveat) and is documented in-repo as +**not** clinical-grade (HIPAA Safe Harbor requires handling free-text narrative +mentions of names/locations/rare ages/device IDs, which regex cannot reliably catch). +**[DATA+CLIN]** — a real de-identification engine needs either a licensed NLP +de-identification service or a clinically-validated model, not a regex list. + +### 2.4 Audit and accountability — **partial, not tamper-evident, no real actor identity** + +`audit-log-store.ts` records `id, timestamp, actionCategory, targetType?, targetId?, +detail?` plus (added this engagement) MCP-specific fields. Confirmed by direct +inspection (`grep -n 'hash|sign|hmac|checksum' audit-log-store.ts` → **no matches**): +**the audit log has no cryptographic integrity protection whatsoever.** It is a flat +JSON array anyone with filesystem access can edit with a text editor, with no hash +chain, no digital signature, and no append-only enforcement at the OS or application +level. There is also **no authenticated actor** on any event — because there's no +identity system (§2.1), "who did this" cannot be recorded beyond "whoever had the app +open." No SIEM export, no central aggregation (every install's audit log is local and +isolated — an institution running 200 clinician workstations has 200 disconnected +audit logs, not one), no access-review report generation, no automated security +alerting. **[SW]**: a hash-chained or signed log format, structured export, and a +SIEM-compatible output format (CEF/syslog) are all directly buildable without external +dependencies. **[SW+CFG]**: central aggregation requires either a server component or +a defined export/ship-to-SIEM pipeline (Filebeat, Fluentd, etc.) configured per +institution. + +### 2.5 Clinical interoperability — **absent entirely (by design, per README)** + +No FHIR client, no SMART on FHIR, no HL7 v2 parser, no CDA handling anywhere in +`app/src` or `frontend/src` (confirmed via grep across both trees — zero matches +for `FHIR|HL7|SMART`). DICOM support is **MCP-tool-mediated only** (`dicom-mcp` +preset, `docs/CLINICAL_WORKSPACE.md`'s "Medical MCP integrations" section) — the app +calls an external, community-maintained, explicitly-prototype MCP server for DICOM +metadata queries; it does not itself speak the DICOM protocol, has no patient-matching +logic, no duplicate detection, and (correctly, per the existing design) no write-back +capability of any kind. Turkish SBYS/e-Nabız integration does not exist in any form. +**[SW]**: a read-only FHIR R4 client (patient/encounter/condition/medication resource +fetch) is buildable as a new MCP-server-equivalent integration, following the same +pattern already established for DICOM MCP (a scoped, denylist-enforced, warning-banner +integration) — but this is genuinely large new work, not a gap-fill. **[LEGAL+CFG]**: +SMART on FHIR requires an institutional EHR's app-registration process; e-Nabız +requires Turkish Ministry of Health authorization that is explicitly outside +engineering scope. + +### 2.6 Medical terminology — **absent entirely** + +No SNOMED CT, LOINC, RxNorm, ICD-10, UMLS, or UCUM handling anywhere in the codebase +(confirmed via grep — the only occurrences of these terms are in `medical-safety.ts` +comments *explaining their absence* and in `docs/CLINICAL_WORKSPACE.md`, which this +engagement wrote to document that absence honestly). Patient Case fields +(`conditions`, `medications`, `allergies` in `patient-cases-store.ts`) are **free-text +string arrays** with no coded-value binding, no terminology version, and no mapping +provenance. **[DATA]**: SNOMED CT, LOINC, RxNorm, and UMLS are licensed vocabularies +(UMLS requires a UTS license even for research use) — none can be bundled into an +open-source-adjacent product without a license agreement per institution. **[SW]**: +the *integration surface* (a terminology-lookup abstraction, coded-value fields +alongside free text, UCUM-based unit normalization for lab values) is buildable now, +ready to plug in a licensed terminology server later. + +### 2.7 Medication and allergy safety — **demonstration-only, explicitly labeled as such** + +`checkMedicationConflicts()` (`medical-safety.ts`) uses two small hardcoded tables: +`ALLERGY_CLASS_SYNONYMS` (3 classes: penicillin, sulfa, NSAID) and +`KNOWN_INTERACTIONS` (5 pairs: warfarin+aspirin, warfarin+ibuprofen, MAOI+SSRI, +sildenafil+nitrate, metformin+contrast dye). The in-repo comment on +`KNOWN_INTERACTIONS` states verbatim: *"NOT a substitute for a licensed +drug-interaction database (e.g. First Databank, Lexicomp, Multum)."* Every UI +surface that renders a warning from this function (`PatientCaseDetail.tsx`) appends +*"Generated by simple keyword matching, not a licensed drug-interaction database. +Verify independently."* **This labeling is a real, load-bearing safety control** — it +correctly prevents the single most dangerous failure mode of a system like this +(silent false confidence from an absent warning) by making the limitation +unavoidably visible at the point of use. No cross-sensitivity beyond the three +allergy classes, no duplicate-therapy detection, no dose-range checking, no +renal/hepatic adjustment, no pregnancy/age/weight/pediatric logic, no formulary +support. **[DATA]**: a real medication-safety engine requires a licensed database +(First Databank/Multum/Lexicomp-class) — this is a data-licensing problem, not an +engineering one. **[SW]**: the *abstraction boundary* — a `MedicationSafetyProvider` +interface `checkMedicationConflicts()` could be refactored behind, with the current +demonstration table as the default/fallback implementation and a licensed-database +adapter pluggable per institution — is directly buildable now and is the concrete, +correctly-scoped "software responsibility" here. + +### 2.8 Clinical AI validation — **absent entirely** + +No intended-use statement beyond the product-boundary language in `README.md` +("clinical decision-support... not an autonomous diagnostician"). No validation +dataset, no clinician-adjudicated reference answers, no hallucination/harmful-omission +metrics, no sensitivity/specificity/calibration measurement, no subgroup evaluation, +no acceptance thresholds, no silent-mode prospective evaluation pipeline, no +human-factors/usability study. **This entire category is [CLIN]** — it cannot be +satisfied by code changes at all. The one thing engineering *can* do is instrument +the product to make such a study possible later (structured logging of model +outputs against the response contract, a review/adjudication UI for clinicians to +mark outputs correct/incorrect) — that instrumentation does not exist today either. +**[SW]**: build the *instrumentation* (structured output logging, a clinician-review +UI, a metrics pipeline) now; **[CLIN]**: the actual validation study itself is not an +engineering deliverable under any circumstance. + +### 2.9 Model governance — **absent entirely** + +`AppSettings.defaultModel` and per-session `model` string +(`sessions-store.ts:ChatSession.model`) are free-text identifiers with no version +pinning beyond whatever string the user typed, no model card, no approved-use flag, +no evaluation gate before a model becomes selectable, no drift detection, no +periodic revalidation requirement, no reproducibility guarantee (temperature/seed are +user-configurable per session but nothing prevents a user from changing them +turn-to-turn). System-prompt/prompt-preset versioning exists in a limited form — +`PromptPreset.versions` (`schemas.ts`) keeps a history when a saved prompt is edited +— but this is a convenience feature, not a governance control (no approval workflow, +no change-control gate). **[SW]**: an approved-model registry (institution-curated +list of `{provider, modelId, version, approvedUseCases, approvedBy, approvedAt}`) +gating what's selectable in the model picker is directly buildable and is a natural +extension of the existing `mcp-presets.ts`/trust-profile pattern already used for MCP +servers. **[CLIN]**: deciding *which* models are approved for *which* use cases is a +clinical/governance decision, not one code can make. + +### 2.10 Output safety — **partial** + +What exists: the 8-section response contract (prompt-level, not enforced), pre-model +deterministic emergency detection (`checkForEmergencyFlags` — genuinely +model-independent, a real control), the "Not verified" badge on every assistant +message (`Chat.tsx`'s `MessageBubble`), transmission preview before remote sends, +and (built but **not wired into the UI** — confirmed via grep, `checkCitations` is +only referenced from its own test file) a citation-verification function that checks +a model's inline citation markers against known Evidence Library sources. **Gap**: +there is no structured *validation* of a model's response against the 8-section +contract — a model that skips "Uncertainty and limitations" or fabricates a citation +is not caught by anything today; the contract is a system-prompt instruction only, +exactly as `docs/CLINICAL_WORKSPACE.md` already discloses. No abstention enforcement +(a model can answer confidently even when the contract asks it to say "insufficient +data"). No mechanism requires an identifiable clinician's sign-off before a +model-drafted note (e.g. a SOAP note) is treated as final — `ClinicalNote.author` +(`patient-cases-store.ts`) does distinguish `"clinician" | "model-inference"` +provenance, which is good, but nothing *enforces* a review step before a +model-inference note could be acted on. **[SW]**: structured-output validation +(parse the response for the 8 required section headers, flag a response missing +any), wiring `checkCitations` into the chat UI, and a review/sign-off gate on +`clinicalNotes` are all directly buildable now. + +### 2.11 Evidence quality — **partial** + +Evidence Library (`evidence-store.ts`) never fabricates title/organization/date — +confirmed by its own test suite (`evidence-store.test.ts`'s "never fabricates a +title when none is found"). This is real and correctly built. Gaps: no automatic +claim-to-source traceability from a model's answer back to a specific Evidence +Library entry (the citation-checking function exists but isn't wired in, per §2.10); +no retraction awareness; no evidence grading (GRADE-style strength-of-evidence +labeling); no guideline-versioning; publication/retrieval dates are captured +(`retrievedAt`, `publishedOrUpdated`) but not surfaced prominently enough to +distinguish "current" from "possibly outdated" evidence in the UI. Patient +facts/retrieved evidence/model inference *are* structurally separated at the data +level (`ClinicalNote.author`, `CaseField.includeInContext`, Evidence Library as a +distinct store) — this separation exists and is a real strength; it's the +*rendering* of that separation in the chat transcript itself (as opposed to the case +page) that's incomplete. + +### 2.12 Operational readiness — **absent** + +No centralized monitoring (single-device app, nothing to centralize into). No HA +concept (desktop app). No backup mechanism of any kind exists — a user's Patient +Cases, chat history, and audit log live only on their local disk with no built-in +backup, encrypted or not.

There is no institutional trusted-MCP-server registry +(any user can add any MCP server locally — this is by design for a single-user app, +but is a gap for institutional deployment where an admin should be able to restrict +which MCP servers are addable at all), no network-egress control beyond the existing +`networkToolsEnabled` global on/off toggle, and no least-privilege *service identity* +concept (there are no services — everything runs as the OS user). **[SW]**: an +institutional MCP-server allowlist (server URL/command must match an admin-approved +list) is a direct, buildable extension of the existing preset/trust-profile pattern. +**[CFG]**: true Windows sandboxing would require either a fundamentally different +process-isolation approach (a Windows container, AppContainer/Job Object-based +confinement) — a genuinely large undertaking, not a quick fix — or accepting the +denylist-only posture as a documented, institution-acknowledged risk for Windows +deployments specifically. + +### 2.14 Accessibility and human factors — **ad hoc, not audited** + +`docs/CLINICAL_WORKSPACE.md`'s own "Known limitations" section already discloses: +"ad hoc `aria-*` labeling, no full WCAG 2.2 AA audit performed on the clinical +pages."

The "Not verified" badge and clinical severity/warning +styling (destructive-red for emergency banners, warning-amber for medication +conflicts) do differentiate facts/warnings/unverified output *visually*, but this +has not been validated for colorblind accessibility or screen-reader announcement +priority (an emergency banner should almost certainly be an `aria-live="assertive"` +region — not confirmed as implemented in this pass). **[SW]**: a WCAG audit pass +and `aria-live` correctness review are directly buildable. **[LEGAL]**: formal +accessibility *certification* (e.g. VPAT) is a compliance-documentation exercise +layered on top of the engineering work. + +--- + +## 3.

Target architecture for institutional deployment + +The current single-process desktop shape is fundamentally incompatible with several +P0 requirements (RBAC, central policy, tamper-evident central audit, SIEM +integration) — these require **something on the other end of a network connection** +that the desktop app talks to, not just more local code. A realistic target +architecture: + +``` +┌─────────────────────────┐ ┌──────────────────────────────────┐ +│ ModelForge Medical │ │ Institutional control plane │ +│ (desktop client, │◄──────►│ - Identity (OIDC/SAML broker) │ +│ this repository) │ HTTPS │ - Policy service (feature flags, │ +│ │ │ model registry, MCP allowlist) │ +│ - Local case cache │ │ - Central audit ingestion (SIEM) │ +│ (encrypted, short-TTL) │ │ - Key management (KMS-backed) │ +│ - Offline-capable for │ │ - Backup/DR orchestration │ +│ local-model inference │ └──────────────────────────────────┘ +└─────────────────────────┘ +``` + +Key architectural decisions this implies: + +1. **Identity moves to the control plane.** The desktop app becomes an OIDC/SAML + *relying party*, not an identity holder — no custom auth is built in-app. +2. **Audit events are shipped, not just stored locally.** Local storage remains + (offline resilience) but every event is also forwarded to a central, + tamper-evident sink as soon as connectivity allows; local logs stay + hash-chained regardless of connectivity so a gap in shipping doesn't create a + gap in integrity. +3. **Policy is pulled, signed, and cached.** The client periodically fetches a + signed policy document (approved models, MCP allowlist, retention rules, + feature flags) and enforces it locally, refusing to operate on an + expired/unverifiable policy past a grace period — this is how "central + revocation" becomes real without requiring permanent connectivity. +4. **Local-first inference is preserved.** This is the product's actual + differentiator and should not be sacrificed for the control plane — local model + inference continues to work fully offline; only identity, policy-refresh, and + audit-shipping require connectivity, and each degrades gracefully (cached + policy, local audit buffering) rather than failing closed in a way that blocks + clinical work. +5. **Key management splits local/central.** Case-encryption keys can remain + passphrase-derived for individual/small-practice deployments (current design, + kept as a supported mode) *or* be wrapped by an institutional KMS for larger + deployments — both modes share the same `case-encryption.ts` interface, just a + different key-provider implementation behind it. + +This is a genuinely large architectural addition (a new backend service this +repository does not currently have any component of), not a set of patches to the +existing Electron app — sizing it accurately matters more than a comforting +smaller estimate. + +--- + +## 6. Phased implementation roadmap + +Dependencies are explicit; nothing after Phase 0 should start before its listed +dependency is done, since building on an unstable foundation (e.g. audit fields +before an identity system exists to populate the actor) means redoing the work. + +### Phase 0 — Foundation (blocks all P0 work) +- Full PHI inventory completion (§2.3's flagged-but-not-fully-inspected stores: + `rag.ts` embeddings, exports, logs, Electron cache/temp). +- Decide target architecture posture (single-device-only vs. control-plane-backed — + §5) — **this is a product decision, not an engineering one**, and everything + downstream depends on it. +- **Acceptance criteria**: written PHI inventory covering every store with + encryption status; a signed-off target-architecture decision document. + +### Phase 1 — Identity, RBAC, central policy (P0) +- Depends on: Phase 0's architecture decision. +- OIDC relying-party integration; role model (clinician/admin/researcher/ + auditor/support) with `patient-level`/`department-level` scoping; break-glass + flow with mandatory justification text, itself an audited event; central policy + fetch-and-cache with signature verification and expiry. +- **Acceptance criteria**: no PHI-bearing action is reachable without a verified + identity and a role check; break-glass access is itself audit-logged with the + justification text; a revoked policy takes effect within the defined grace + period even offline-then-reconnected. + +### Phase 2 — Tamper-evident audit + PHI encryption completion (P0) +- Depends on: Phase 1 (for authenticated actors on every event). +- Hash-chain or sign every audit event; extend encryption-at-rest to + `sessions.json`, exports, and any PHI-bearing cache/temp path found in Phase 0's + inventory; central audit shipping with local buffering. +- **Acceptance criteria**: any out-of-band edit to the local audit log file is + detectable; every store in the Phase 0 inventory marked "PHI: high" is + encrypted at rest; audit events survive a network outage and ship on + reconnection without loss or duplication. + +### Phase 3 — Model/MCP governance (P0/P1) +- Depends on: Phase 1 (policy delivery mechanism). +- Approved-model registry gating the model picker; institutional MCP-server + allowlist enforced client-side against the fetched policy; evaluation-gate + workflow before a model/MCP server can be marked approved. +- **Acceptance criteria**: a non-approved model/MCP server is not selectable in + the UI, not just discouraged; an admin can revoke approval and it takes effect + per Phase 1's policy-refresh mechanism. + +### Phase 4 — Clinical interoperability, read-only (P0/P1) +- Depends on: Phase 1 (identity/authorization — patient-context sync requires + knowing *who* is allowed to see *which* patient), Phase 3 (an EHR integration + is itself a governed "tool"). +- Read-only FHIR R4 client (patient/encounter/condition/medicationrequest + resources), SMART on FHIR launch flow, patient matching (deterministic, not + probabilistic, to start), source provenance tagging on every imported field. +- **Acceptance criteria**: no write-back capability exists at all in this phase + (explicitly deferred); every FHIR-sourced field is visibly tagged with its + source and retrieval time in the UI, matching the existing + `ClinicalNote.author` provenance pattern. + +### Phase 5 — Terminology + licensed medication safety (P1) +- Depends on: Phase 0 (architecture decision affects whether terminology service + is local or centrally hosted), a signed data-license agreement (external to + engineering). +- `MedicationSafetyProvider` abstraction (keep the current demonstration table as + the default fallback, explicitly labeled, exactly as today); pluggable + terminology-lookup interface; UCUM unit normalization on lab-result entry. +- **Acceptance criteria**: swapping the demonstration medication-safety table for + a licensed adapter requires no changes outside the adapter implementation; + every terminology-coded field records its code system and version. + +### Phase 6 — Output safety hardening + evidence provenance (P1) +- Depends on: nothing above — can run in parallel with Phases 1-5. +- Structured-response validation against the 8-section contract; wire + `checkCitations` into the chat UI; evidence-grading labels in Evidence Library; + a review/sign-off gate before a `clinicalNotes` entry with + `author: "model-inference"` is treated as final. +- **Acceptance criteria**: a response missing a required contract section is + visibly flagged, not silently accepted; an unresolvable citation marker is + rendered as unverified in the transcript, not just internally computed. + +### Phase 7 — Operational readiness (P1) +- Depends on: Phase 2 (backup must cover the now-fully-encrypted stores). +- Encrypted backup mechanism with defined RPO/RTO; SBOM + Dependabot in CI; + code-signing for releases; documented incident-response runbook. +- **Acceptance criteria**: a restore-from-backup drill succeeds against a + synthetic dataset; CI fails the build on a newly-disclosed critical CVE in a + direct dependency. + +### Phase 8 — Accessibility + maturity (P2) +- WCAG 2.2 AA audit and remediation; `aria-live` correctness pass on + emergency/warning banners; localization validation for clinical content. + +--- + +## 7.

A soft + cap (`MAX_EVENTS` + `TRIM_BATCH` = 5000 + 100) keeps this fast + indefinitely instead of reverting to O(n)-per-write forever once an + install's audit log first reaches capacity — a real cliff that a smaller + first version of this fix had (see "What stress testing caught" below). + +## Test suites and results + +| Suite | Tool | Files | Tests | Result | +|---|---|---|---|---| +| Rust unit | `cargo test` | 4 modules (`datastore`, `download`, `manager`, root) | 37 | ✅ 37 passed | +| Rust format/lint | `cargo fmt --check`, `cargo clippy -- -D warnings` | — | — | ✅ clean | +| App unit (native addon built) | `vitest` | 41 | 570 | ✅ 570 passed | +| App unit (native addon absent — CI's default) | `vitest` | 41 | 570 | ✅ 569 passed, 1 skipped* | +| Frontend unit | `vitest` | 14 | 95 | ✅ 95 passed | +| Frontend lint/typecheck | `eslint`, `tsc -b` | — | — | ✅ clean | +| App typecheck/build | `tsc`, `tsc -p` | — | — | ✅ clean | +| E2E (real Electron app, Playwright) | `playwright test` | 6 specs | 9 | ✅ 9 passed | + +\* The one skipped test (`stays correct across multiple trim cycles (2x the +cap)`) is a large-scale stress test that's only meaningful with the native +addon's fast-append path active — without it, it would legitimately take +minutes of pure O(n²) work to prove something the smaller cap test already +covers, so it's guarded with `it.skipIf(!nativeAddonPresent)` rather than +slowing down the standard CI run for no additional signal. + +Every suite above was run **twice**: once with the native addon built +(`npm run build:debug` in `lib/`), once with `app/native/` temporarily moved +aside to force the pure-TypeScript fallback path. Both runs pass with +identical test *results* — only timing differs, which is exactly the +property this change is supposed to have (a pure performance optimization, +zero behavior change). + +## New tests added this round + +- `lib/src/datastore.rs` — 8 new Rust tests for `append_json_array_element`: + missing file, empty file, non-array tail, truncated array, append onto an + empty array, append onto a compact array, append onto a pretty-printed + (indented) array, and a 50-iteration repeated-append order/content check. +- `app/src/native-datastore.test.ts` — a 4th test (`appendJsonArrayElementNative`) + covering both the addon-present and addon-absent branches. +- `app/src/audit-log-store.test.ts` — 3 new tests: + - **Multi-trim-cycle stress test** (10,010 events, 2× the cap): proves the + soft-cap design stays correct — bounded size, valid hash chain, newest + event always retained — across many trim cycles, not just the original + single 10-events-over-cap case. + - **Self-healing under external mutation**: writes directly to + `audit-log.json` between two `recordEvent()` calls (simulating a text + editor, restored backup, or another process) and confirms the store + notices (via the mtime/size checkpoint) and reseeds instead of trusting + a now-stale cached hash — and confirms `verifyChainIntegrity()` still + correctly reports the resulting anomaly as broken, rather than the + self-healing silently "fixing" what is a genuine tamper signal. + - **Informational timing benchmark**: 2,000 sequential `recordEvent()` + calls, logged (not just asserted) so the number is visible in test + output; asserted only against a generous 20s ceiling meant to catch a + regression back to O(n²), not to pin an exact number. +- `e2e/tests/audit-log-persistence.spec.ts` (new spec, 1 test): drives the + real Electron app — create a patient case → confirm the resulting + `case-created` audit event appears in the Audit & Privacy page → click + "Verify integrity" → relaunch against the same profile → confirm the event + and a valid integrity check both survived to disk. This is the one place + in the whole suite that never knows or cares whether native or fallback + served the write — it only checks that the end-to-end behavior is + correct, which is the actual guarantee this change needs to hold. + +## Timing comparison + +All numbers are real, from this sandbox, for the 5,010-event scenario the +original bottleneck was reported and measured against +(`audit-log-store.test.ts`'s "caps retained events instead of growing +without bound", later widened to 5,110 events to actually exercise the new +soft cap): + +| Configuration | Time for ~5,000 sequential audit events | +|---|---| +| Before any Rust migration (pure Node/TS, full read-modify-write + `crypto` hash per write) | ~20–23s | +| Rust I/O + hashing, but still full read-modify-write per write (first migration pass) | ~20–21s (I/O/hash constant factor only — the O(n²) shape was unchanged) | +| Rust I/O + hashing + O(1) append + soft-cap trimming (final) | **~0.3s** | +| Same final code, native addon *not* built (fallback path) | ~22–24s (unchanged from "before" — confirms zero regression when the addon is unavailable) | + +That's roughly a **70×** improvement for the scenario that motivated this +work, achieved by fixing the actual algorithmic shape (O(n²) → effectively +O(n) below the soft cap) rather than only speeding up the same repeated +work in a faster language. + +The larger 2×-cap stress test (10,010 events, only run with the addon +present) completes in **~1–1.5s**. Extrapolating the old O(n²) behavior to +that same scale would have taken on the order of minutes. + +## What stress testing caught (and fixed) + +The first version of this fix (committed before this test-writing pass) +handled the *ramp-up* phase correctly — 0 up to the 5,000-event cap — but +fell back to a full read-modify-write on literally every single event once +at or over the cap, because the cap was enforced exactly. That's fine for a +5,010-event test (only 10 events pay the slow-path cost), but it means any +install that runs long enough to actually *reach* its audit log cap — which +real usage over weeks/months will — reverts to the original O(n)-per-write +cost forever afterward, for its entire remaining lifetime. The large-scale +(10,010-event, 2× cap) stress test added in this pass is what surfaced this: +it timed out at the original 60s budget instead of the sub-2-second result +the smaller test showed. + +Fix: the cap became a **soft cap** — `MAX_EVENTS` (5,000, unchanged, +still what Settings → Audit & Privacy and every existing test describes) +plus a `TRIM_BATCH` (100) of slack. The file is allowed to grow up to +5,100 events before a single full-array trim brings it back down to +exactly 5,000, so the O(n) trim cost is amortized over 100 appends instead +of paid on every one — capacity is a steady state the fast path stays in +indefinitely, not a wall it hits once and never leaves. + +## Correctness properties preserved (unchanged by any of this) + +- **Tamper-evidence never trusts the cache.** `verifyChainIntegrity()` and + `listEvents()` always re-read the real file from disk — the in-memory + cache exists purely to make `recordEvent()`'s own bookkeeping cheap, and + is never consulted for anything that needs to be actually trustworthy. +- **Retention purging is exact when active.** Age-based retention + (Settings → Audit & Privacy) still forces the full read-modify-write path + on every write while enabled, since purging by age requires seeing every + event's timestamp — unchanged from before this work, verified by the + pre-existing "purges expired events on write too" test. +- **On-disk format is unchanged.** Still a plain JSON array + (`JSON.stringify`-compatible), still readable by literally every existing + test that does `JSON.parse(fs.readFileSync(auditLogPath()))` directly — + nothing about this change required a migration or a new file format. +- **Every fallback is exercised, not just written.** Every "falls back to + X" comment in the code was verified by actually forcing that path (hiding + the built addon, or in the Rust tests, feeding malformed/missing files + directly) and confirming the fallback produces the same result the + primary path would have. diff --git a/docs/RUST_MIGRATION_ASSESSMENT.md b/docs/RUST_MIGRATION_ASSESSMENT.md new file mode 100644 index 0000000..3f58ad1 --- /dev/null +++ b/docs/RUST_MIGRATION_ASSESSMENT.md @@ -0,0 +1,234 @@ +# Rust Native-Core Migration — Assessment (Phase 0 deliverable) + +Required initial deliverable before any Phase 1+ code changes, per the +migration brief.

Measured baselines + +From [docs/RUST_DATASTORE_TEST_REPORT.md](RUST_DATASTORE_TEST_REPORT.md), +reused rather than re-measured: + +- 5,000 sequential audit events: ~20–23s (pre-Rust) → ~0.3s (Rust + O(1) + append + soft cap). +- 10,010 events / 2× the cap (multi-trim-cycle stress test): ~1–1.5s with + the addon; the equivalent pure-Node cost was not exercised at that scale + (extrapolated to minutes) because it isn't representative of any real + code path once this migration lands. + +**Not yet measured** (would need to precede any Phase 1+ work on these +specific modules): RAG query latency at realistic collection sizes (10³–10⁵ +chunks), `case-encryption.ts`'s `scryptSync` wall time on this machine's +CPU, `workspace-path.ts` call frequency under a long agent run, +`resource-monitor.ts` polling overhead. None of these have a reported user +complaint or profiled bottleneck in this repository today — the brief's own +P1/P2 framing (RAG, ingestion, GPU inspection, safety scanning, recommender +inference) versus P0 (persistence, crypto, filesystem/process security) +already reflects that the P0 items are risk/security-driven, not +measured-bottleneck-driven, and should be scoped accordingly. + +## 5. Proposed N-API interfaces (for Phase 1, not implemented this pass) + +Sketch only — these must be refined against real characterization tests +before implementation, per the brief's own "minimal typed N-API interface" +step: + +``` +store_open(path: String, schema_version: u32) -> StoreHandle +store_migrate(handle) -> MigrationReport +store_insert_json(handle, table: String, json: String) -> Result<String /* id */> +store_query_json(handle, table: String, filter: String) -> Result<Vec<String>> +store_transaction(handle, ops: Vec<Op>) -> Result<()> +store_backup(handle, dest: String) -> Result<()> +store_verify_integrity(handle) -> IntegrityReport +``` + +Every function returns structured, stable error codes (missing file, +corrupt schema, migration-in-progress, busy-timeout, etc.) rather than a +single generic `napi::Error::from_reason` string — the current datastore +functions use string reasons because their failure modes are simple +(missing file, not-an-array); a transactional store's failure modes are not, +and callers (audit sign-off UI, patient case error banners) need to +distinguish them. + +## 6. Persistent-data migration plan (Phase 1, not started) + +Recommended order matches the brief: audit → patient cases/case-linked +sessions → evidence/model registry → general sessions/projects → other. +For each store: characterization tests against current JSON behavior first, +then a Rust-backed implementation run side-by-side against the same test +vectors (native vs. fallback vs. new-store, three-way comparison, not just +two), then a feature flag, then — only after verified — a one-way, +backed-up, idempotent migration. The original JSON is never deleted +automatically; every existing `*-store.ts` already keeps this discipline +(see `json-store.ts`'s corrupted-file backup behavior) and the SQLite +migration should extend it, not relax it. + +Provider secrets already live in `secrets-store.ts` behind +`safeStorage`/OS keychain, separate from the general JSON stores — this +plan does not propose moving them into the same SQLite database. + +## 7. Rollback strategy (Phase 1, not started) + +Each per-store migration ships behind a flag defaulting to the existing +JSON path. Rollback is "the flag was never flipped" for anyone who hasn't +opted in, and "restore the retained JSON backup" for anyone who has — which +is why the migration plan above insists the JSON backup is retained until +the new store's integrity check passes, not deleted at write time. + +## 8. Platform build matrix + +napi-rs's own targets (already declared in +[lib/package.json](../lib/package.json)): `x86_64-pc-windows-msvc`, +`x86_64-apple-darwin`, `aarch64-apple-darwin`, `x86_64-unknown-linux-gnu`. +**This sandbox is Linux x86_64 only** — every verification in this pass and +in the prior Rust-datastore work was necessarily Linux-only. The CI +`rust` job in [ci.yml](../.github/workflows/ci.yml) also only runs on +`ubuntu-latest`. This is a real, standing gap: nothing in this repository's +current CI actually builds or loads the `.node` addon on Windows or macOS, +despite shipping installers for both. Closing this (a Phase 0 item in the +brief) requires CI runner access this environment doesn't have — flagged +here rather than silently left undone. + +## 9. Phase-by-phase acceptance criteria + +- **Phase 0** (this pass): docs reconciled with actual native-addon scope; + native load-failure modes distinguished instead of collapsed into one + boolean; existing fallback-path tests still pass. *Not done this pass* + (blocked on infrastructure this sandbox lacks): multi-platform CI build + jobs, cross-platform load verification. +- **Phase 1+**: not started. Acceptance criteria per the brief's own + Phase 1 requirements list (WAL mode, migrations, transactional writes, + backup/restore, corruption reporting, etc.) apply unchanged; this + assessment doesn't relax any of them. + +## 10. Files expected to change (Phase 1, if/when undertaken) + +`lib/Cargo.toml` (new `rusqlite` or equivalent dependency), new +`lib/src/store/` module tree, `lib/src/lib.rs` (thin N-API surface only, per +the brief's own "don't grow one oversized lib.rs" rule), a new +`app/src/native-sqlite-store.ts` bridge mirroring `native-datastore.ts`'s +fallback pattern, and — one at a time, per the recommended order — +`audit-log-store.ts`, then `patient-cases-store.ts`/`sessions-store.ts`, +then `evidence-store.ts`/`model-registry-store.ts`. `docs/ARCHITECTURE.md` +and this assessment both get updated as each slice lands. + +--- + +## What was actually changed in this pass (Phase 0, minimal slice) + +Per the brief's own closing instruction — "implement only Phase 0 and the +smallest vertical slice of Phase 1 unless the evidence shows another first +slice is safer" — the evidence above (no profiled bottleneck on any P0 +non-persistence item, and persistence's own Phase 1 being a multi-day, +high-risk, schema-migrating undertaking that cannot be safely finished and +verified in one pass) points to *not* starting Phase 1 at all yet. What +shipped alongside this document: + +1. **`docs/ARCHITECTURE.md` reconciled** — its native-addon section + described download-only; corrected to include the datastore/audit + functions added in the prior session. +2. **Native load-failure modes distinguished** — `native-datastore.ts` and + `native-downloader.ts` previously collapsed every failure (`require()` + throwing for *any* reason — missing file, wrong ABI, corrupted binary, + unsupported platform, or an exception during the addon's own init code) + into a single "unavailable, fall back" boolean. `getNativeCapabilityReport()` + now inspects the thrown error and reports which of those it actually + was, purely for diagnostics/logging — every existing fallback behavior + is unchanged. + +**Explicitly not done, with reasons, per "stop and document the blocker" +rather than half-finish:** + +- Multi-platform CI build/load jobs — this sandbox has no Windows/macOS + runner access; the CI YAML change itself would be easy, but "add a job" + without being able to verify it actually builds and loads the addon + there is exactly the kind of unverified change this brief says not to + ship. +- Any Phase 1+ code (SQLite store, crypto vault, RAG index, filesystem + capability layer, process supervisor, system-inspection rewrite, + ingestion, safety-scanning engine, recommender inference) — none of it + was started. Each is a substantial, independently-scoped project per the + brief's own phase breakdown; starting one without the characterization + tests, benchmarks, and migration/rollback machinery the brief itself + requires first would produce exactly the "half-migrated" state the brief + says to avoid. diff --git a/e2e/tests/audit-log-persistence.spec.ts b/e2e/tests/audit-log-persistence.spec.ts new file mode 100644 index 0000000..3eae651 --- /dev/null +++ b/e2e/tests/audit-log-persistence.spec.ts @@ -0,0 +1,44 @@ +import { test, expect } from "@playwright/test"; +import { launchApp, makeUserDataDir, type LaunchedApp } from "../fixtures/electron-app"; + +// Exercises the real IPC path end to end — Patient Cases UI -> +// patientCases:create -> app/src/audit-log-store.ts's recordEvent() -> +// audit-log.json (via json-store.ts / the Rust addon when built) -> Audit & +// Privacy UI -> audit:list / audit:verifyIntegrity.

Adds lib/src/store/audit.rs (rusqlite, bundled SQLite, WAL mode, schema-versioned, idempotent migration-from-JSON) with a TypeScript bridge (app/src/native-sqlite-store.ts) - built, tested through the real addon, and deliberately NOT wired into audit-log-store.ts's live path yet, per the assessment's own rollback plan (ship inert, cut over behind a flag later). Also fixes a real build issue this surfaced: adding rusqlite broke 'cargo test' linking for the whole crate (undefined references to napi's own C-ABI symbols, normally supplied by the Node process at runtime) because this crate had napi's 'dyn-symbols' feature off. Re-verified the built addon still loads correctly under Node after turning it on.

From 79baf71311164017ad9e1983d50dd6af0f710aca Mon Sep 17 00:00:00 2001 From: Salih Yilboga <salihyilboga98@gmail.com> Date: Mon, 3 Aug 2026 23:20:42 +0300 Subject: [PATCH 03/30] rust: flagged opt-in SQLite cutover for audit-log-store.ts Continues the Phase 1 SQLite scaffold (previous commit) from inert to actually reachable, gated behind a new Settings field (auditLogBackend: "sqlite", default unset/"json" - completely unaffected). Two new Rust functions support it: get_last_audit_event_hash and list_audit_events_json (same field shape as the JSON file, so verifyChainIntegrity()/listEvents() reuse their existing logic unchanged regardless of backend). Existing JSON events migrate in on first write after opting in; JSON is never deleted. clearAll() now clears both backends so switching afterward can't resurrect old events either way. 4 new parity/integration tests plus a fallback test (requesting sqlite without the addon silently and correctly keeps using JSON), verified through the real built addon both with and without it present. Known, documented gaps for this experimental first slice: no retention purging or row cap on the SQLite backend yet (real but lower-urgency than the JSON O(n^2) fix, since SQLite inserts don't have that growth problem), and no Settings UI toggle - see docs/RUST_MIGRATION_ASSESSMENT.md.

New audit:sqliteCapability IPC handler surfaces getSqliteStoreCapabilityReport() so the UI can explain *why* the toggle is disabled when the native addon isn't built, rather than it silently doing nothing. Audit & Privacy gets a new "Audit log storage backend" card: current backend badge, a disabled state with reason text when SQLite isn't available, and a switch button that migrates existing events in automatically (JSON is never deleted, so switching back is always possible). New e2e spec (audit-sqlite-backend-toggle.spec.ts) drives the real Electron app: create a case on JSON, switch to SQLite, confirm the migrated event survived, switch back, confirm it's still there. Screenshotted the resulting Audit & Privacy page to confirm visual placement. Full e2e suite (10 specs) and unit suites (581 app + 95 frontend) all still pass.

Two new Rust functions, trim_audit_events_to_cap and purge_audit_events_older_than - both single indexed DELETEs, cheap regardless of table size (unlike the JSON backend's full-file-rewrite equivalent, which is why that backend needed a soft cap with batching in the first place). audit-log-store.ts's SQLite write path now enforces the same MAX_EVENTS/TRIM_BATCH cap and age-based retention as the JSON backend, with equivalent semantics (purge runs on every write when retention is configured; trim still batches to avoid a DELETE per insert, though a single trim isn't expensive here either). Found and fixed a real bug in the process: get_last_audit_event_hash crashed on a legacy-shaped last event (NULL event_hash column) - none of the original tests exercised that case. A new TypeScript retention integration test seeded exactly that shape and caught it. Fixed by reading the column as Option<String> and flattening the two independently-nullable layers instead of assuming non-null. New dedicated Rust test covers it directly. 7 new tests (4 Rust: trim/purge correctness and no-op cases, 1 Rust bug regression test, 2 TypeScript bridge tests) plus 1 new integration test proving retention purge works end-to-end through the real SQLite path. Verified through the real built addon, with and without it present, plus full e2e suite (10/10) and app unit suite (584/585, 1 intentional skip).

When unset — every deployment + before this variable existed — `DATABASE_URL` is used for both, exactly + as before: one role does everything, and RLS remains inert. + +To actually enable enforcement, create a role named exactly +`modelforge_runtime` before running migrations — +`migrations/010_runtime_role_grants.sql` conditionally grants it (and +every future tenant schema `009`'s provisioning function creates) exactly +what it needs, and is a complete no-op if this role doesn't exist: + +```sql +CREATE ROLE modelforge_runtime WITH LOGIN PASSWORD '...' + NOSUPERUSER NOCREATEDB NOCREATEROLE NOBYPASSRLS NOREPLICATION; +GRANT CONNECT ON DATABASE modelforge_iam TO modelforge_runtime; +``` + +then set `RUNTIME_DATABASE_URL` to that role's connection string.

See `src/cache/` for the implementation; this +section is the operational summary. + +### Backends + +- **In-memory (`MemoryCache`, default)** — per-process, lost on restart. + Fine for local development and a single-instance deployment. +- **Redis (`RedisCache`, `REDIS_URL` set)** — shared across every instance + of this service, so a write on one instance is visible to every other + instance's next read instead of each carrying its own cold cache. + `docker compose up -d redis` (`docker-compose.yml`, this directory) runs + one locally. + +Both implement the same `Cache<V>` interface (`src/cache/cache.ts`) and the +same generation-tagged-key correctness scheme — see that file and +`redis-cache.ts`/`memory-cache.ts`'s doc comments for the full detail. They +differ in a few ways that can't be made equivalent: + +| | MemoryCache | RedisCache | +|---|---|---| +| Capacity bound | `maxSize` (LRU-evicted) | none — Redis's own `maxmemory`/`maxmemory-policy` | +| Expired-entry reclaim | proactive periodic sweep + lazy on read | Redis's own internal TTL expiry | +| Stampede coalescing | per-process | per-process only (not cross-instance) | +| Invalidation failure | cannot fail | can fail (Redis unreachable) → **degraded mode**, below | + +Since `RedisCache` never enforces a size cap itself, a deployment running +against Redis should configure Redis's own `maxmemory` and +`maxmemory-policy` (e.g. `volatile-lru`, since every key this service +writes already carries a TTL) rather than relying on this process to +bound memory. + +### Negative caching + +Every `T | null` lookup here (`getUser`, `getOrganization`, `getGroup`, +`getPolicy`) caches a *found* result but never a miss — with one +deliberate exception: `findUserByExternalSubject`, called on every request +to an org-scoped route. An authenticated caller with no account in the +target organization is a real, repeating request pattern (an outsider +retrying, or a caller pointed at the wrong org), not a one-off — so that +miss is cached too, at a much shorter TTL (`CACHE_NEGATIVE_TTL_MS`, +default 5s, vs. `CACHE_TTL_MS`'s default 30s) than a found user. +`createUser`/`updateUser` invalidate it through the exact same cache key +and mechanism as a positive result — no separate invalidation path exists +or is needed. See that method's doc comment in `caching-iam-store.ts` for +the full reasoning, including why every other id lookup deliberately does +*not* do this (their ids are server-generated UUIDs a legitimate caller +only ever has after the entity exists). + +### Why a policy or group change clears the whole effective-policy cache + +`resolveEffectivePolicies` depends on a user's own policies *and* every +policy attached to every group it belongs to. There's no reverse index +from a policy or group back to the users it affects, and building one (to +narrow invalidation to just the affected users) would trade a rare, +already-cheap admin write for correctness risk on the read side that +matters far more: this is an authorization cache, and an incorrectly- +narrowed invalidation would leak a stale `Allow`/`Deny` decision to a +request that has nothing to do with the write that just happened. Given +that trade, a group or policy mutation invalidates the entire +`effectivePolicies` cache namespace; a user update invalidates only that +one user's entry (unambiguous — no index needed). Group/policy writes are +rare admin operations; `/authz/check` is not, so this favors correctness +on the hot path over narrowing the cost of the cold one. + +### Stampede coalescing + +A burst of concurrent requests all missing on the same freshly-expired (or +never-cached) key join a single in-flight load instead of each issuing +their own backing-store query — see each `Cache<V>` implementation's doc +comment for how this stays safe under a concurrent invalidation (a caller +never coalesces onto a load that started before an invalidation its own +request arrived after). + +### Failure mode: Redis unreachable + +If Redis becomes unreachable, every cache **read** degrades to a cache +miss (correctness-neutral — the request just falls through to the store, +slower but never stale). If Redis becomes unreachable during a +**write-invalidation** (a policy revoked, a user suspended, mid-outage), +that specific cache namespace enters a **degraded** state: every read +bypasses the cache entirely (never risking serving what might still be the +pre-invalidation value) until a generation-bump operation actually +succeeds again. Recovery is automatic and needs no operator action — +retried opportunistically on the next read to that namespace, and +proactively as soon as the shared Redis connection reports healthy again +(the `ready` event, `src/cache/create-cache.ts`). This only protects the +process that observed the failure; a multi-instance deployment relies on +the shared Redis `INCR` itself (one counter, not one per process) for +cross-instance consistency. + +### Failure mode: Redis restored from a stale backup + +"Unreachable" isn't the only failure shape — an operator can also restore +Redis from a backup taken *before* a revoking mutation, which silently +undoes that mutation's own cache-invalidation call along with everything +else, potentially resurrecting a stale `Allow` under its original key. This +is exactly what "Redis outage cannot preserve an allow decision" +(docs/ENTERPRISE_ARCHITECTURE_ROADMAP.md's P0 item 9) is about: an outage +alone already can't (see above); a full data rollback is the harder case +this section covers. + +`resolveEffectivePolicies` closes it with a durable, per-organization +authorization epoch (`IamStore.getAuthorizationEpoch`, bumped by +`updateGroup`/`updatePolicy`/`deletePolicy` atomically with their own +mutation — see that method's doc comment). The cached value is tagged with +the epoch it was computed under; every read compares that tag against the +current epoch, fetched through `CachingIamStore`'s own small +`authorizationEpochs` cache — deliberately **always in-process, never +Redis-backed**, so the comparison target can't be rolled back along with +the rest of Redis. A resurrected stale entry's tag reads as older than the +current epoch and is recomputed rather than served. That epoch cache's own +TTL (2s, `EPOCH_CACHE_TTL_MS`) bounds how long this specific failure mode +could still serve a stale decision — not zero, but a small, fixed window +after what is already a rare, deliberate operational event, not an +ongoing exposure. + +### Observability + +`CachingIamStore.stats()` returns per-sub-cache `{hits, misses, size, +loads, coalesced, loadTimeMsTotal, evictions, expirations, invalidations, +redisErrors, degraded}` (`src/cache/cache.ts`'s `CacheStats`) — counts +only, never a cached key or value, so it's safe to log or expose without +risk of leaking a subject identifier, user id, or policy document. This +service logs one structured line (`{"event":"cache_stats", ...}`) per +sub-cache every 5 minutes (`src/index.ts`), plus an immediate line +whenever a Redis-backed cache enters or leaves degraded mode +(`{"event":"cache_degraded"|"cache_recovered", ...}`) and on every caught +Redis operation failure (`{"event":"cache_redis_error", ...}`) — grep for +these in production logs to correlate a degraded-cache period with what +Redis itself was doing. + +These same `stats()` numbers are also exposed as Prometheus gauges on `GET +/metrics` (`src/metrics.ts`), alongside HTTP/authorization-decision/ +audit-write latency histograms and audit-write outcome counts — see +[docs/OBSERVABILITY.md](../../docs/OBSERVABILITY.md) for the full metric +list, the importable Grafana dashboard at `server/observability/` +`grafana-dashboard.json`, and how each panel maps to the roadmap's §17 +provisional SLOs. `/metrics` is unauthenticated by default (every metric it +reports is a bounded-label aggregate, never a caller- or tenant-identifying +value) — set `METRICS_TOKEN` for a second layer if an operator wants one. +There's still no separate authenticated *diagnostic* endpoint beyond this — +a route that could return raw per-key cache state was judged more new +attack surface than this cache layer alone warrants; `stats()` remains +available programmatically to any future tool that wants it on demand. + +### Configuration + +See `.env.example` for the full list (`CACHE_DISABLE`, `CACHE_TTL_MS`, +`CACHE_NEGATIVE_TTL_MS`, `REDIS_URL`). `CACHE_TTL_MS` and +`CACHE_NEGATIVE_TTL_MS` are validated at startup — a malformed or +out-of-range value (non-numeric, negative, or outside the [1s, 1h] / +[100ms, `CACHE_TTL_MS`] bounds respectively) fails loudly with a +`ConfigError` rather than silently producing a cache that never expires or +expires every entry immediately. Every other numeric env var (`PORT`, +`POOL_MAX`, `POOL_*_TIMEOUT_MS`, `RATE_LIMIT_MAX`, `RATE_LIMIT_WINDOW_MS`) +gets the same treatment, for the same reason — a typo'd value fails startup +instead of silently becoming `NaN` somewhere downstream. + +`loadConfig` (`src/config.ts`) also refuses to start against insecure +production-shaped configuration: + +- **`OIDC_ISSUER` must be HTTPS**, unless it's an explicit + `http://localhost` / `http://127.0.0.1` / `http://[::1]` address (local + development only) — a plaintext issuer makes JWKS/discovery tamperable in + transit, a direct path to accepting forged tokens.

CI (`.github/workflows/ci.yml`'s `server` job) runs the +whole suite against real Postgres and Redis service containers, so the +gated suites above are actually exercised on every push/PR, not just when a +developer happens to run them locally. + +`npm run build && npm start` builds to `dist/` and runs the compiled output. + +## Identity: generic OIDC, not one vendor + +`OIDC_ISSUER` and `OIDC_AUDIENCE` (both required) point at any +spec-compliant OIDC provider — Cognito User Pools, Keycloak, or anything +else. `src/auth/oidc-verifier.ts` verifies a bearer token's signature +(against the issuer's JWKS, resolved via `OIDC_JWKS_URI` directly or OIDC +discovery), issuer, audience, and expiry. Nothing here is Cognito- or +Keycloak-specific — this is deliberate, per +docs/ENTERPRISE_MULTIUSER_ARCHITECTURE.md §4's decision to decide the actual +IdP per deployment topology rather than hard-code one. + +`OIDC_AUDIENCE` is required, not just recommended, specifically because +this is a *generic* relying party: without checking `aud`, a validly-signed +ID token — or an access token minted for a completely different client of +the same IdP — would verify successfully here (same issuer, same signing +key, a real `sub` claim) and be treated as a genuine access token for this +API. `aud` is the portable, spec-defined way (RFC 7519 §4.1.3) to rule that +out without coupling this service to one provider's own token-type claim +(e.g. Cognito's `token_use`). + +The verified token's `sub` claim becomes `User.externalSubject` — the only +thing tying a `User` record to a real identity. This service never stores a +password or any other credential. + +### Multiple identity providers, proxies, and custom certificate authorities + +(docs/ENTERPRISE_ARCHITECTURE_ROADMAP.md P2 item 3: "proxy, custom CA, and +multiple-IdP compatibility.") + +**Multiple IdPs.** Set `OIDC_ADDITIONAL_ISSUERS` to a JSON array of +`{issuer, audience, jwksUri?}` objects to accept tokens from more than one +IdP at once — e.g. migrating between providers, or federating a legacy +on-prem provider alongside a new cloud one. `OIDC_ISSUER`/`OIDC_AUDIENCE` +remain required and always trusted; this is purely additive. Each issuer +still needs its own real, HTTPS discovery/JWKS endpoint and a distinct +issuer string — a token is routed to the right issuer's keys by its own +(unverified) `iss` claim, but that routing is never itself the security +check: `src/auth/oidc-verifier.ts`'s `verifyAccessToken` independently +re-validates the real signature and issuer against whichever issuer got +selected, so a token that merely *claims* a trusted issuer without actually +being signed by it is rejected the normal way. Example: + +```bash +OIDC_ADDITIONAL_ISSUERS='[{"issuer":"https://idp-b.example-hospital.org","audience":"modelforge-iam-server-b"}]' +``` + +**HTTP(S) proxy.** This process's outbound calls (OIDC discovery, JWKS +fetch) use Node's global `fetch`. If your network requires all outbound +traffic through a corporate proxy, set `NODE_OPTIONS=--use-env-proxy` (Node +≥ 22) and the standard `HTTP_PROXY`/`HTTPS_PROXY`/`NO_PROXY` environment +variables — no application code or configuration here is needed, since this +is a Node runtime capability that applies to every outbound HTTPS call this +process makes. + +**Custom/internal certificate authority.** If your IdP (or anything else +this process calls over HTTPS) presents a certificate issued by an internal +or self-signed CA, set `NODE_EXTRA_CA_CERTS=/path/to/your-ca-bundle.pem` — +again a Node runtime capability, not something this service implements or +needs to. Do not disable certificate validation (`NODE_TLS_REJECT_UNAUTHORIZED=0`) +as a substitute for this: that disables validation for every TLS connection +this process makes, including to your database and object storage. + +## Authorization: real IAM-style JSON policy documents + +A `Policy` is a named JSON document of statements, not a fixed role enum: + +```json +{ + "version": "2026-01-01", + "statements": [ + { + "sid": "AllowCaseViewInCardiology", + "effect": "Allow", + "actions": ["patientCase:view"], + "resources": ["organization:org-1/*"], + "condition": { "StringEquals": { "user:department": "cardiology" } } + } + ] +} +``` + +- **Actions/resources** support `*` as a wildcard (`patientCase:*`, + `organization:org-1/*`) — matched by `src/domain/policy-evaluator.ts`'s + `matchesPattern`, a fixed pattern language, never a policy-author-supplied + regex (that would make a policy document a code-injection-shaped surface + instead of a data-shaped one). +- **Conditions** support `StringEquals`/`StringNotEquals` against a context + map. `user:id` and `user:organizationId` are always injected server-side + by `src/routes/guards.ts`'s `requirePermission` *after* any caller-supplied + context, so a caller can never override its own resolved identity by + sending a context key with the same name. +- **Evaluation semantics are AWS IAM's**: default deny (nothing matched → + deny), and an explicit `Deny` statement always overrides any number of + matching `Allow` statements, regardless of order or which policy they're + in. See `src/domain/policy-evaluator.test.ts` for the full behavior matrix. +- **Policies attach to a `User` directly, to a `Group` the user belongs to, + or both** — `IamStore.resolveEffectivePolicies` unions and de-duplicates + across both before evaluation. +- **A `User` can optionally carry a permission boundary** + (`permissionBoundaryPolicyId`, another AWS IAM concept) — a single policy + that caps what their own policies (direct + via groups) can ever grant, + regardless of how permissive those are. The effective decision is Allow + only if *both* the identity's own policies and the boundary allow it; see + `src/domain/policy-evaluator.ts`'s `evaluateWithBoundary`. Useful for + safely delegating `iam:managePolicies` to a sub-admin without risking + them (or anyone they grant access to) exceeding a defined ceiling. + Setting or changing it is gated behind `iam:managePolicies`, same as + `policyIds` (see the table below). **Fails closed**, not open: if the + referenced policy is later deleted, the reference is left dangling on + purpose (no foreign key at the storage layer) so + `src/routes/guards.ts`'s `resolveEffectivePoliciesWithBoundary` denies + that user everything rather than silently treating a vanished boundary + as no boundary at all. `POST /organizations/:id/authz/check` — documented + below as "the primitive every other service is meant to call" — goes + through this same resolution, not a bare policy evaluation, so it never + gives a different answer than every other route already enforces for the + same user. + +## Bootstrapping the first admin + +`POST /organizations` is the one deliberate exception to "every other +endpoint requires an existing account with the right permission": creating +an organization requires only a valid bearer token (any authenticated +identity), because no organization exists yet for a permission check to be +scoped against. The caller automatically becomes that organization's admin, +via a `builtin: true` policy (`src/domain/builtin-policies.ts`) granting +`*` on `organization:{id}` and `organization:{id}/*` — scoped to that one +organization only, never wider. Every other route requires the caller to +already hold an account with the relevant `iam:*` permission in the target +organization; there is no self-service sign-up path beyond that one +bootstrap case. + +## API surface + +| Method | Path | Auth | Notes | +|---|---|---|---| +| GET | `/health` | none | Original combined probe (kept for back-compat) — DB-aware, same as `/health/ready` below | +| GET | `/health/live` | none | Liveness probe — never depends on Postgres; "this process can answer HTTP" only | +| GET | `/health/ready` | none | Readiness probe — DB-aware; `503 degraded` when configured `healthCheck` fails | +| GET | `/metrics` | none (optional `METRICS_TOKEN`) | Prometheus exposition — see [docs/OBSERVABILITY.md](../../docs/OBSERVABILITY.md) | + +Before promoting a candidate deployment, build the server and run the platform-neutral canary gate with `CANARY_BASE_URL=https://candidate... npm run ops:canary`.

Server-side support +only: nothing in `app/`'s client currently generates/retries with a key +(there's no offline-queue/retry loop yet to reuse one across attempts) — see +`docs/ENTERPRISE_ARCHITECTURE_ROADMAP.md`'s "Offline edit and reconnect" +flow for the client-side half this sets up for. + +**Audit log** (`src/store/audit-store.ts`): every IAM mutation +(organization/user/group/policy create/update/delete) and every case +write/delete records an entry — who (`actorExternalSubject`, plus +`actorUserId` once a User record exists), what (`action`, a fixed +`<resource>.<verb>` vocabulary like `"policy.delete"`), and which record +(`targetType`/`targetId`). Immutable: no update or delete method is exposed +by this store, by design. On Postgres, the audit row is written inside the +*same transaction* as the mutation it records (`insertAuditEntry`, called +with the mutation's own `PoolClient`) — a rolled-back mutation writes no +audit row, and a committed mutation can't fail to produce one; this is the +"transactional outbox" property +docs/ENTERPRISE_ARCHITECTURE_ROADMAP.md's P0 item 11 asks for. The +in-memory mode has no transactions to join (nothing here does), so the +same guarantee holds trivially: `InMemoryIamStore`/`InMemoryCaseStore` +append the entry synchronously, in the same call, right alongside the +in-memory mutation itself — one shared `InMemoryAuditStore` instance is +passed to both (see `index.ts`) so IAM and case mutations merge into one +chronological trail, the same thing Postgres mode gets from both stores +writing into the same `audit_log` table. **Not included**: a publisher +that ships entries to an external system — nothing reads this table today +except `GET /organizations/:id/audit` itself; wiring a real "outbox" (a +process that tails new rows and forwards them) is separate work with no +concrete external destination yet to build against. + +Every non-bootstrap, non-`/me` route requires an active first-class +membership for the authenticated human or service principal +(`src/routes/guards.ts`). A valid OIDC token without a membership gets +`403`, not a silent empty result and not auto-provisioning. A narrow legacy +fallback remains for pre-migration `User` rows that do not yet have an +`Identity`; once an identity exists the new membership model fails closed. + +## Known gaps in this slice + +- **No server-side encryption of case data** (see "What this is not" + above) — `InMemoryCaseStore` holds plaintext in process memory, + `PostgresCaseStore` stores plaintext JSONB (`patient_cases.data`); a real + deployment needs Postgres-level encryption (TDE, encrypted volumes) + configured by whoever operates it. This is the server-managed-keys + trade-off docs/ENTERPRISE_MULTIUSER_ARCHITECTURE.md §7 names explicitly, + not silently assumed away. +- **`PostgresIamStore`, `PostgresCaseStore`, `PostgresCaseMigrationStore`, + and `postgres-rls.test.ts`'s role-separation/RLS penetration tests are + untested against a real database in this environment** (see + "Persistence" and "Role separation" above) — the SQL has been reviewed + carefully, including the Postgres-documented interaction between RLS and + FK-triggered cascade deletes (`deleteOrganization`'s cleanup relies on + cascades bypassing RLS rather than being blocked by it), but none of it + is proven by execution. Run with `DATABASE_URL` (and, for the + role-separation tests specifically, `RUNTIME_DATABASE_URL` pointed at a + real `modelforge_runtime` role) before trusting any of this in + production. +- **Role separation has no retroactive-grant path for an already-populated + database** — `010_runtime_role_grants.sql`'s `ALTER DEFAULT PRIVILEGES` + only covers tables created *after* `modelforge_runtime` exists. Every + environment this ships to today (CI, any fresh deployment) creates the + role before the first organization is bootstrapped, so the gap doesn't + arise there; an operator turning on role separation against an existing, + already-populated database needs to run the equivalent `GRANT`s by hand + once, against each existing tenant schema, first. +- **Staged case migration has no persisted reconciliation report or + rolled-back-data retention policy** — `activate()` now re-checks for a + destination that changed since validation (concurrent case creation) + before applying anything, and a failed activation/rollback attempt + cleans up after itself (see `in-memory-case-migration-store.ts`'s and + `postgres-case-migration-store.ts`'s doc comments), but there is no + durable, queryable record of *what a completed activation actually did* + beyond the migration's own `preview` snapshot, and no scheduled cleanup + of `rolled-back` migrations' staged data — both are real features, not + bugs, and need their own design pass. +- **`SharedBackendConnectionSection` (the Settings UI) has not been + visually verified in a running Electron window** — no display was + available in the environment it was built in. It typechecks cleanly and + its underlying calls (`app/src/shared-backend-auth.ts`, + `app/src/shared-backend-client.ts`, + `app/src/shared-patient-cases-backend.ts`) are unit-tested against a + mocked `fetch`, but the component itself — state transitions, + form-then-connect-then-pick-organization flow, error rendering — has + only been read-reviewed, not clicked through. +- **Version threading from the Electron UI is now real, but only for + edits/deletes made through `PatientCaseDetail.tsx`/`PatientCases.tsx`** — + both screens now pass the case's loaded `version` through + `patientCases:update`/`patientCases:delete` and surface a + `CaseWriteConflictError` as a toast + automatic reload rather than + silently overwriting a concurrent edit. `grantConsent`/`revokeConsent`/ + `addClinicalNote`/`reviewClinicalNote` remain intentionally + version-unaware (see `app/src/patient-cases-store.ts`'s doc comments on + each — they're additive/append operations, not whole-record overwrites, + so there is no "base snapshot" to protect). +- **No refresh-token handling, logout, or session concept** — this service + only ever verifies a bearer token per request; session lifecycle is + entirely the IdP's responsibility, consistent with delegating + authentication to it. +- **No request logging beyond Fastify's own, or production TLS + termination** — assumed to sit behind a reverse proxy/load balancer in any + real deployment, not configured here. (Rate limiting *is* configured — + see the API surface section above and `.env.example`'s `RATE_LIMIT_*`.) +- **The audit log (see "Audit log" above) has no publisher/outbox consumer + and no hash-chaining** — every mutation is durably recorded and readable + via `GET /organizations/:id/audit`, but nothing ships those entries + anywhere external yet, and entries aren't cryptographically chained + against tampering.

Keying by the *data* key (which embeds + * both generation counters) gives the same safety property MemoryCache's + * coalescing has: a concurrent delete()/clear() changes what data key the + * *next* caller computes, so it can never join a load that a since-landed + * invalidation has already made stale. + * + * While degraded (below), there's no generation to key by — every value is + * a direct, uncached passthrough to `loader()`, so a `DEGRADED_COALESCE_PREFIX`- + * prefixed key derived from the bare `key` argument is used instead. This + * is exactly when coalescing matters most: a Redis outage is precisely the + * condition under which a burst of concurrent requests could otherwise + * each fall through to Postgres independently and turn a cache outage into + * a database overload too. + * + * ## Failed invalidation must never be silent + * + * If the INCR behind delete()/clear() itself fails (Redis unreachable), + * this cache cannot claim the invalidation happened — the counter didn't + * move, so any value cached under the old counter is still exactly as + * reachable as before the call. Silently treating that as success (as a + * bare "log and swallow" would) is how a Redis outage during a permission + * revocation could leave the revoked grant servable from cache once Redis + * reconnects. Instead this cache flips into a `degraded` state: every + * getOrLoad() bypasses the cache entirely (reads the store directly, + * caches nothing) until a generation bump actually succeeds. Recovery + * happens two ways: opportunistically, retried on the next getOrLoad() + * call while degraded; and proactively, via `recoverIfDegraded()`, which + * create-cache.ts calls on every cache instance when the shared ioredis + * client reports its `ready` event (i.e. as soon as the connection itself + * is confirmed healthy again, without waiting for the next request to this + * particular namespace). A successful bump, however it's reached, is by + * itself sufficient to guarantee correctness again: it advances the + * namespace generation past whatever an in-flight load from *before* or + * *during* the outage could have captured, so any such load's eventual + * write is orphaned exactly like the normal case above. + * + * This only protects the process that observed the failure. A + * multi-instance deployment sharing one Redis needs every instance to + * agree "this generation is dead" — which the shared INCR already gives + * them, since it's one counter in Redis, not one per process.
