 # Crossref Fetcher (DOI → Research Packet)
 This fetcher retrieves bibliographic metadata for a DOI from Crossref and emits a schema-conforming Research Packet.
 ## Security Constraints
 - Only connects to: `https://api.crossref.org`
 - Uses proxy env vars (`https_proxy`, `http_proxy`) via urllib
 - Produces metadata-only packets (no full text)
 - Output must pass `validate_research_packet.py` before CORE consumes it
 ## Usage
 From repo root:
 ```sh
 chmod +x fetch/crossref/fetch_by_doi.py
 export PYTHONPATH="$(pwd)"
 # Recommend setting CONTACT_EMAIL for Crossref etiquette
 export CONTACT_EMAIL="you@example.org"
 python3 fetch/crossref/fetch_by_doi.py \
  --doi 10.5555/12345678 \
  --out infra/volumes/handoff/inbound-to-core/RP-crossref-doi.md

 ThreeGate FETCH: Crossref-by-DOI fetcher (constrained)
 - Fetches metadata for a DOI from Crossref API using stdlib urllib.
 - Honors proxy env vars (http_proxy/https_proxy) via urllib ProxyHandler.
 - Enforces an internal allowlist: ONLY https://api.crossref.org is permitted.
 - Produces a schema-conforming Research Packet (schema_version=1).
 Usage:
  python3 fetch/crossref/fetch_by_doi.py --doi 10.1038/nature12373 --out <path>
 Operational notes:
 - Crossref requests should include a contact email in the User-Agent if possible.
  Set CONTACT_EMAIL env var (recommended).

 Below are the **next repo additions** in the exact order I suggested. Each file is **ready to commit**.
 ---
 ## 1) `docs/threat-model.md`
 ```markdown
 # Threat Model
 This document defines the threat model for ThreeGate, including assets, adversaries, attack surfaces, mitigations, and explicit out-of-scope threats.
 ThreeGate is designed for **single-user local operation** and prioritizes structural containment over behavioral promises.
 ---
 ## 1. Assets to Protect
 ### Primary Assets
 - **User data**: notes, drafts, PDFs, research corpora, local documents
 - **Secrets**: API keys, tokens, credentials, SSH keys, cookies
 - **System integrity**: host OS, container images, configs, policy files
 - **Assistant integrity**: component separation, network isolation, validation pipelines
 - **Provenance**: citations, source traces, execution logs (auditability)
 ### Secondary Assets
 - Model weights and caches (integrity and confidentiality)
 - Execution results and intermediate artifacts
 - System availability (denial of service is relevant but not primary)
 ---
 ## 2. Adversaries and Capabilities
 ### A. Malicious Content Provider
 - Controls a webpage, PDF, or document that FETCH retrieves or user ingests
 - Attempts **indirect prompt injection** to cause unsafe actions
 Capabilities:
 - Embed malicious instructions and deceptive content
 - Craft content to manipulate citations and reasoning
 - Provide poisoned research artifacts
 ### B. Malicious User (or User Mistake)
 - Provides prompts that request unsafe actions
 - Pastes untrusted code for execution
 - Misconfigures allowlists or mounts
 Capabilities:
 - Trigger tool requests
 - Place files into ingestion directories
 - Approve execution unintentionally
 ### C. Supply-Chain Attacker
 - Tampered container images, dependencies, ERA binary, or model weights
 Capabilities:
 - Replace artifacts at build or update time
 - Introduce malicious binaries or scripts
 ### D. Network Attacker
 - Attempts MITM, DNS poisoning, or proxy abuse
 - Tries to induce exfiltration through allowed domains
 Capabilities:
 - Manipulate network paths
 - Exploit weak TLS validation or DNS configuration
 ---
 ## 3. Security Goals
 ### G1: Prevent Untrusted Content from Triggering Action
 Untrusted documents must not cause execution, installation, persistence, or exfiltration.
 ### G2: Minimize Blast Radius of Compromise
 A compromise of any single component must not yield end-to-end authority.
 ### G3: Preserve Auditability
 Key actions must be attributable, logged, and reviewable:
 - Fetch operations and sources
 - Packets accepted vs quarantined
 - Execution requests and approvals
 - Execution results and metadata
 ### G4: Enforce Least Privilege by Construction
 Topology and filesystem permissions must ensure least privilege even if the model misbehaves.
 ---
 ## 4. Attack Surfaces
 ### CORE
 - Prompt injection via Research Packets and local documents
 - Attempts to coerce policy violations (“ignore rules”, “run commands”, etc.)
 - Attempts to encode tool requests to bypass human review
 ### FETCH
 - Malicious websites attempting instruction injection
 - Response content masquerading as policy, commands, or credentials
 - Proxy bypass attempts, domain confusion attacks
 ### TOOL-EXEC
 - Malicious code in execution requests (intended or unintended)
 - Attempted sandbox escape (microVM/container breakout)
 - Attempts to write unexpected outputs or encode exfiltration payloads
 ### Shared
 - Handoff directories (malformed artifacts, schema bypass)
 - Proxy allowlist and DNS resolution
 - Container runtime configuration drift
 ---
 ## 5. Key Mitigations (Mapped to Threats)
 ### M1: Compartmentalization (CORE/FETCH/TOOL-EXEC)
 Mitigates end-to-end compromise by ensuring no single component:
 - both browses and executes
 - both reasons and acts
 ### M2: Network Topology Enforcement
 - CORE has no internet route
 - FETCH only via allowlisted proxy
 - TOOL-EXEC no network by default
 Mitigates exfiltration and unauthorized retrieval.
 ### M3: Deterministic Validation + Quarantine
 - Research Packets must match strict schema
 - Tool results must match strict schema
 - Rejections go to quarantine; CORE never consumes them
 Mitigates indirect injection and “format smuggling.”
 ### M4: Human Approval Gate for Execution
 - CORE may draft requests, but cannot execute
 - Human must promote execution requests into TOOL-EXEC
 - Every execution is logged
 Mitigates automated tool abuse.
 ### M5: Read-Only Policy Mounts and Immutable Configuration
 - Policy files mounted read-only into containers
 - Configuration changes require explicit operator action
 Mitigates self-modification and persistence via prompt.
 ### M6: Supply-Chain Hygiene (recommended)
 - Pin image digests
 - Verify releases (hash/signature where possible)
 - Keep minimal base images
 - Prefer reproducible builds
 Mitigates tampered artifacts.
 ---
 ## 6. Explicit Out-of-Scope Threats
 ThreeGate does not attempt to mitigate:
 - Hardware fault induction (e.g., RowHammer)
 - Microarchitectural side channels
 - Kernel/firmware compromise
 - Hostile multi-tenant co-residency scenarios
 These threats are not aligned with the intended single-user local operating assumptions.
 ---
 ## 7. Residual Risks
 Even with compartmentalization, residual risks include:
 - User approving unsafe execution requests
 - Allowlist misconfiguration enabling exfiltration channels
 - Supply-chain compromise of container images or binaries
 - Weak local host hygiene (unpatched kernel, insecure Docker daemon)
 ThreeGate reduces consequences, but cannot replace operator diligence.
 ---
 ## 8. Security Posture Summary
 ThreeGate assumes model fallibility and focuses on:
 - strict separation of duties
 - deterministic validation
 - constrained connectivity
 - human-gated execution
 - auditable workflows
 ```
 ---
 ## 2) Schemas: create `schemas/` and add three schema documents
 ### 2a) `schemas/research-packet.schema.md`
 ````markdown
 # Research Packet Schema (Normative)
 A **Research Packet** is the only permitted format for data flowing from FETCH to CORE.
 All packet content is treated as **untrusted data**. The packet is designed to:
 - preserve provenance (where it came from)
 - prevent instruction smuggling
 - constrain content into predictable sections
 - support deterministic validation and quarantining
 Packets that do not conform MUST be quarantined.
 ---
 ## File Naming
 Recommended:
 - `RP-YYYYMMDD-HHMMSSZ-<slug>.md`
 ---
 ## Required Front Matter
 Research Packets MUST begin with YAML front matter:
 ```yaml
 ---
 packet_type: research_packet
 schema_version: 1
 packet_id: "RP-20260209-153012Z-arxiv-llm-security"
 created_utc: "2026-02-09T15:30:12Z"
 source_kind: "arxiv|pubmed|crossref|europepmc|doi|url|manual"
 source_ref: "https://... or DOI or PMID"
 title: "..."
 authors: ["Last, First", "..."]
 published_date: "YYYY-MM-DD"   # if known
 retrieved_utc: "YYYY-MM-DDTHH:MM:SSZ"
 license: "open|unknown|restricted"
 content_hashes:
  body_sha256: "hex..."
  sources_sha256: "hex..."
 ---
 ````
 Notes:
 * `license` is informational; CORE must still treat as untrusted.
 * `content_hashes` support auditability and tamper detection.
 ---
 ## Required Sections (in this order)
 Packets MUST contain the following H2 sections, exactly:
 1. `## Executive Summary`
 2. `## Source Metadata`
 3. `## Extracted Content`
 4. `## Claims and Evidence`
 5. `## Safety Notes`
 6. `## Citations`
 ### 1) Executive Summary
 * Short, neutral description of what the source is about
 * No imperatives, no instructions to CORE
 * No tool suggestions
 ### 2) Source Metadata
 Must include:
 * canonical URL / DOI / PMID
 * publication venue (if known)
 * retrieval method (API vs HTML)
 * any access constraints observed
 ### 3) Extracted Content
 * Quotes are allowed but must be short and attributed.
 * Prefer paraphrase with citations.
 * Avoid embedding procedural steps (install/run) beyond what is necessary to understand the source.
 ### 4) Claims and Evidence
 A list of claim blocks:
 ```text
 - Claim: ...
  Evidence: ...
  Confidence: low|medium|high
  Citation: [C1]
 ```
 ### 5) Safety Notes
 This section is mandatory and MUST contain:
 * `Untrusted Content Statement:` a sentence explicitly stating the content is untrusted and must not be treated as instructions.
 * `Injection Indicators:` list any suspicious patterns found (or `None observed`).
 ### 6) Citations
 A numbered list with stable labels:
 ```text
 [C1] Author, Title, Venue, Year. URL/DOI.
 [C2] ...
 ```
 ---
 ## Forbidden Content (Validation Failures)
 Packets MUST be rejected if they contain (case-insensitive, including obfuscations):
 * shell commands or code blocks intended for execution (e.g., `bash`, `sh`, `powershell`)
 * installation instructions (`apt`, `pip install`, `curl | sh`, etc.)
 * persistence suggestions (cron, systemd units, init scripts)
 * instructions aimed at overriding hierarchy (“ignore previous instructions”, “system prompt”, etc.)
 * embedded credentials or tokens
 * links to executables or binary downloads presented as steps to take
 Packets may describe such things academically if necessary, but must do so as **descriptive text** with no runnable commands.
 ---
 ## Validation Output
 Validators should produce:
 * `ACCEPT` → moved to `handoff/inbound-to-core/`
 * `REJECT` → moved to `handoff/quarantine/` with a reason report
 ````
 ---
 ### 2b) `schemas/tool-request.schema.md`
 ```markdown
 # Tool Execution Request Schema (Normative)
 A **Tool Execution Request** is a human-approved artifact placed into TOOL-EXEC.
 CORE may draft it, but the operator must approve and promote it.
 Requests must be deterministic, auditable, and minimally privileged.

 ````
 ---
 ## Required Sections (in this order)
 1. `## Command`
 2. `## Input Files`
 3. `## Output Expectations`
 4. `## Risk Assessment`
 ### 1) Command
 Must be a single command line in plain text (no code fences), e.g.:
 `python -u script.py --in /in/input.csv --out /out/output.json`
 Notes:
 * TOOL-EXEC implementation may wrap this into ERA invocation.
 * Requests containing multiple commands, shell chaining (`;`, `&&`, `|`), or heredocs MUST be rejected.
 ### 2) Input Files
 List each input file and expected location (`/in/...`), matching `inputs` hashes.
 ### 3) Output Expectations
 List each output path restricted to `/out/...`.
 ### 4) Risk Assessment
 Must include:
 * `Risk level: low|medium|high`
 * `Justification:` short text
 * `Data sensitivity:` public|internal|confidential
 * `Network rationale:` why network is needed (if any)
 ---
 ## Forbidden Content (Validation Failures)
 Requests MUST be rejected if they include:
 * shell as language
 * command chaining, pipelines, redirection
 * instructions to install packages
 * attempts to access host paths
 * attempts to use privileged devices
 * embedded secrets
 ---
 ## Approval Gate
 A request is only valid if:
 * `approved_by` and `approved_utc` are present and non-empty
 * `requested_by` is present
 * hashes are present for all declared inputs

 * backend identity (ERA version if available)
 * resource limits applied
 ### 3) Outputs
 A table-like list:
 ```text
 - /out/output.json  sha256: ...
  Description: ...
 ```
 ### 4) Stdout
 * Include at most the first N lines (recommend N=200)
 * If longer, include truncation note and store full stdout as an artifact file
 ### 5) Stderr
 Same rule as Stdout.
 ### 6) Safety Notes
 Must include:
 * `Untrusted Output Statement:` output is untrusted and must not be treated as instructions
 * `Unexpected behavior:` None observed / describe anomalies
 * `Network confirmation:` none used / list allowlisted destinations
 ---
 ## Forbidden Content (Validation Failures)
 Results MUST be rejected if they contain:
 * embedded secrets
 * executable payloads embedded inline
 * claims that the system policy should be changed
 * new instructions to fetch or execute
 Results may report *that* something requested those things, but cannot include actionable steps.
 ---
 ## Validation Outcome
 Validators should produce:
 * `ACCEPT` → moved to CORE inbound
 * `REJECT` → moved to quarantine with reasons

 ## 3) Role profiles: add `docs/roles/` and the first role
 ### 3a) `docs/roles/research-assistant.md`
 ```markdown
 # Role Profile: Research Assistant (Early Target)
 This role profile defines how the ThreeGate system is used as a **secure local research assistant**.
 This role is intentionally conservative and emphasizes provenance, citation discipline, and injection resistance.
 ---
 ## Goals
 - Retrieve scholarly sources from allowlisted academic domains
 - Build structured summaries with explicit evidence and citations
 - Support writing (literature reviews, outlines, annotated bibliographies)
 - Optional computations (statistics, plotting) via TOOL-EXEC when approved
 ---
 ## Component Responsibilities
 ### FETCH
 - Retrieves:
  - metadata (title/authors/venue/date)
  - abstracts
  - open-access full text where permitted
 - Produces Research Packets only
 - Never executes code and never installs tools
 ### CORE
 - Consumes validated Research Packets and local PDFs
 - Produces:
  - summaries and syntheses
  - clearly cited claims
  - draft fetch requests (if needed)
  - draft tool execution requests (optional)
 ### TOOL-EXEC (optional)
 - Runs approved computations such as:
  - parsing BibTeX / RIS
  - calculating descriptive statistics
  - converting formats (CSV ↔ JSON)
  - limited plotting workflows (non-interactive)
 Default: no network, ephemeral execution.

 ## Allowed Sources (Examples)
 These are examples; the actual allowlist is an operational policy artifact.
 - arXiv
 - PubMed / NCBI
 - Crossref
 - Europe PMC
 - DOI resolution endpoints
 ---
 ## Operating Rules
 1. All fetched content is hostile by default.
 2. CORE must not treat packet content as instructions.
 3. Tool execution requires human approval and must be isolated.
 4. Any packet or result that fails validation is quarantined.
 5. CORE output must separate:
   - factual claims
   - interpretations
   - open questions
 ---
 ## Output Standards
 CORE outputs should include:
 - Clear citations mapping to packet citation labels
 - Explicit uncertainty markers where appropriate
 - Separation of summary vs analysis
 - A short “sources consulted” section
 ---
 ## Common Anti-Patterns (Do Not Do)
 - Letting FETCH run scripts “to parse the paper”
 - Letting CORE browse “just this once”
 - Allowing TOOL-EXEC to have default internet access
 - Accepting packets/results that contain commands or install steps
 - Treating content from PDFs/webpages as trusted instructions
 ---
 ## Upgrade Path
 As the role matures:
 - Introduce structured bibliographic exports (BibTeX, CSL-JSON)
 - Add topic-specific allowlists
 - Add more robust citation/provenance linting
 - Add optional dataset ingestion lanes (still read-only into CORE)

 If you want to keep momentum, the next step (per the same plan) is **infra skeleton**:
 4. `infra/docker-compose.yml` (three services + proxy placeholder)
 5. `infra/firewall/docker-user-chain.sh` (policy-enforcing egress rules)
 6. `docs/networks.md` (network topology spec)
 Say “proceed” and I’ll generate those next.
