No stubs, no remaining tasks. All tested on real hardware. +**Test Infrastructure**: SSH access to `tensor01.dartmouth.edu` (credentials in `.credentials`) + +--- + +## User Scenarios & Testing + +### User Story 1 — Cryptographically Verified Attestation (Priority: P1) + +A coordinator receives an attestation quote from a donor node and verifies the full certificate chain — not just structure, but real RSA/ECDSA cryptographic signatures — against pinned root CA certificates (AMD ARK for SEV-SNP, Intel DCAP for TDX, manufacturer roots for TPM2). Invalid chains are rejected. Rekor transparency entries include full Merkle inclusion proof verification against the signed tree head. + +**Why this priority**: Without real cryptographic verification, the system accepts any well-formed attestation. This is a Safety First (Principle I) violation — the single most critical gap. + +**Independent Test**: Present known-good AMD SEV-SNP certificate chain → accepted. Present chain with wrong root fingerprint → rejected. Submit Rekor entry → retrieve inclusion proof → verify against signed tree head. Run on `tensor01.dartmouth.edu` with real TPM hardware. + +**Acceptance Scenarios**: + +1. **Given** a valid TPM2 EK certificate chain, **When** the validator processes it, **Then** the chain is accepted and trust tier is assigned based on measurement match +2. **Given** a certificate chain with an expired intermediate, **When** the validator processes it, **Then** the chain is rejected with a clear error +3. **Given** a Rekor log entry, **When** the inclusion proof is retrieved, **Then** the proof validates against the published signed tree head +4. **Given** a tampered inclusion proof, **When** verification is attempted, **Then** the proof is rejected + +--- + +### User Story 2 — Agent Lifecycle and Preemption (Priority: P1) + +A donor installs the agent, enrolls, receives heartbeat-based lease offers from the broker, executes work, pauses (checkpointing active sandboxes), resumes, and withdraws cleanly leaving zero host residue. The preemption supervisor delivers SIGSTOP within 10ms of a keyboard event, attempts checkpoint within 500ms, and escalates to SIGKILL if needed. + +**Why this priority**: Principle III (Donor Sovereignty) requires sub-second preemption and clean lifecycle. Without this, donors cannot safely participate. + +**Independent Test**: Run agent on `tensor01.dartmouth.edu`. Enroll → receive work → inject keyboard event → measure SIGSTOP latency (<10ms) → checkpoint → resume → withdraw → scan for residual files/processes (must find zero). + +**Acceptance Scenarios**: + +1. **Given** an enrolled agent, **When** a heartbeat is sent, **Then** the broker responds with available lease offers +2. **Given** a running workload, **When** a keyboard event fires, **Then** SIGSTOP reaches all sandbox processes within 10ms (measured) +3. **Given** a paused agent, **When** resume is issued, **Then** the agent resumes from checkpoint and continues processing +4. **Given** a withdrawing agent, **When** withdrawal completes, **Then** zero files, processes, scheduled tasks, or network state remain on host + +--- + +### User Story 3 — Policy Engine Completion (Priority: P1) + +A job submission passes through all 10 steps of the deterministic policy engine: identity verification, signature check, artifact registry CID lookup (with real resolution against the ApprovedArtifact registry), workload class check, quota check, egress allowlist validation (declared endpoints checked against approved list), data classification, ban check, and optional LLM advisory. Each step produces an immutable audit record. + +**Why this priority**: The policy engine is the gatekeeper for all workload execution. Incomplete steps mean unsafe jobs can be dispatched. + +**Independent Test**: Submit job with approved CID and approved endpoints → accepted. Submit job with unknown CID → rejected. Submit job with undeclared network endpoint → rejected. + +**Acceptance Scenarios**: + +1. **Given** a job with a valid artifact CID in the registry, **When** submitted, **Then** it passes the artifact check +2. **Given** a job with an unknown CID, **When** submitted, **Then** it is rejected with error code WC-006 +3. **Given** a job declaring endpoints not on the approved list, **When** submitted, **Then** it is rejected at the egress allowlist step +4. **Given** artifact signer and approver are the same identity, **When** submitted, **Then** it is rejected (separation of duties) + +--- + +### User Story 4 — Sandbox Depth: GPU, Firecracker Rootfs, Incident Containment (Priority: P1) + +GPU passthrough is verified via real IOMMU group inspection. Firecracker VMs boot from OCI images fetched from the CID store and assembled into rootfs.ext4. Incident containment primitives (FreezeHost, QuarantineWorkloadClass, BlockSubmitter, RevokeArtifact, DrainHostPool) execute real enforcement effects — not just audit records. + +**Why this priority**: Without GPU verification, unsafe passthrough is possible. Without rootfs preparation, Firecracker cannot run real workloads. Without containment enforcement, incidents cannot be responded to. + +**Independent Test**: On `tensor01.dartmouth.edu`: enumerate GPUs → verify IOMMU groups → store OCI image in CID store → assemble rootfs.ext4 → boot Firecracker VM → execute workload → verify output. Trigger FreezeHost → verify all sandbox processes stopped within 60s. + +**Acceptance Scenarios**: + +1. **Given** a GPU in a singleton IOMMU group, **When** passthrough is requested, **Then** it is allowed +2. **Given** a GPU in a shared IOMMU group, **When** passthrough is requested, **Then** it is rejected +3. **Given** an OCI image stored in the CID store, **When** rootfs preparation runs, **Then** a bootable ext4 image is produced +4. **Given** a FreezeHost containment action, **When** executed, **Then** all sandbox processes on the target host are stopped within 60 seconds +5. **Given** a QuarantineWorkloadClass action, **When** a job of that class is submitted, **Then** it is rejected by the policy engine + +--- + +### User Story 5 — Security: Adversarial Tests, Confidential Compute, mTLS, Supply Chain (Priority: P1) + +All 8 adversarial test scenarios are fully implemented (not `#[ignore]`/`unimplemented!()`). Confidential compute provides client-side AES-256-GCM encryption with TPM-attested key release. mTLS certificates are issued per-account with 90-day auto-rotation. Release binaries are reproducibly built and code-signed. + +**Why this priority**: Principle I (Safety First) requires these before any external deployment. + +**Independent Test**: Run sandbox escape test (ptrace from inside Firecracker → must fail). Encrypt job → execute on attested node → decrypt result → verify correct. Generate mTLS cert → authenticate → verify accepted → exceed rate limit → verify 429. + +**Acceptance Scenarios**: + +1. **Given** a sandbox escape attempt via ptrace, **When** executed inside Firecracker VM, **Then** the attempt fails and is logged +2. **Given** a Byzantine donor injecting wrong results, **When** 100 tasks are audited, **Then** the donor is detected and quarantined +3. **Given** a job with confidential-medium classification, **When** key release is requested without valid TPM attestation, **Then** key release is denied +4. **Given** a new account, **When** an mTLS certificate is issued, **Then** it authenticates successfully and auto-rotates before 90-day expiry +5. **Given** two independent builds from the same git commit, **When** compared, **Then** they produce identical binary output + +--- + +### User Story 6 — Integration Test Coverage and Churn Validation (Priority: P1) + +All 12 previously untested src/ modules have integration tests. The churn simulator validates 80% job completion at 30% node churn over a 72-hour run. The Phase 1 LAN testnet runs on 3+ physical machines with mDNS discovery, R=3 job execution, preemption, and failure recovery. + +**Why this priority**: Principle V (Direct Testing) is non-negotiable. No component ships without real-hardware evidence. + +**Independent Test**: Run full test suite → verify every src/ module has integration coverage. Deploy 3+ nodes on `tensor01.dartmouth.edu` cluster → form cluster via mDNS → run R=3 job → kill one node → verify job completes from checkpoint. + +**Acceptance Scenarios**: + +1. **Given** the full test suite, **When** run, **Then** every src/ module has at least one integration test (zero untested modules) +2. **Given** a 20+ node testbed with 30% churn, **When** jobs are submitted over 72 hours, **Then** at least 80% complete correctly +3. **Given** 3 physical machines on a LAN, **When** agents start, **Then** they form a cluster via mDNS in under 5 seconds +4. **Given** a running R=3 job, **When** one node is killed, **Then** the job reschedules from checkpoint and completes correctly + +--- + +### User Story 7 — Runtime Systems: Credits, Storage, Scheduler, Ledger (Priority: P2) + +Credits decay at 45-day half-life with floor protection. Storage enforces per-donor caps with garbage collection. The scheduler performs real ClassAd-style matchmaking with lease management. The ledger uses t-of-n threshold signing with CRDT merge. + +**Why this priority**: Required for sustained multi-node operation, but not blocking initial testing. + +**Independent Test**: Simulate 90 days of credit earn/spend → verify decay curve. Fill donor storage to cap → verify GC triggers. Submit job → verify broker matches to capable node → kill executor → verify rescheduling. Start 5 coordinators → sign ledger entry → verify 3-of-5 threshold. + +**Acceptance Scenarios**: + +1. **Given** credits earning over 90 days, **When** decay is applied, **Then** the balance follows the 45-day half-life curve within 1% tolerance +2. **Given** a donor at storage cap, **When** new data arrives, **Then** expired data is garbage collected to make room +3. **Given** a job requiring GPU capabilities, **When** submitted, **Then** the broker matches it only to GPU-capable nodes +4. **Given** 5 coordinator nodes, **When** a ledger entry is signed, **Then** 3-of-5 threshold signature is valid + +--- + +### User Story 8 — Platform Adapters: Slurm, Kubernetes, Cloud, Apple VF (Priority: P2) + +The Slurm adapter connects to a real Slurm head node and dispatches jobs via sbatch. The Kubernetes adapter watches a ClusterDonation CRD and creates Pods. The cloud adapter verifies instance identity via metadata services. The Apple VF helper binary uses real Virtualization.framework APIs. + +**Why this priority**: Adapters extend reach to HPC, cloud, and macOS but are not required for core functionality. + +**Independent Test**: Deploy Slurm adapter on `tensor01.dartmouth.edu` (if Slurm available) → submit SHA-256 test job → verify correct result. Deploy K8s operator on minikube → apply CRD → verify Pod created. Build Apple VF helper on macOS → boot VM → execute workload. + +**Acceptance Scenarios**: + +1. **Given** a Slurm cluster, **When** the adapter is installed, **Then** jobs are dispatched via sbatch and results collected +2. **Given** a Kubernetes cluster with the operator deployed, **When** a ClusterDonation CRD is applied, **Then** capacity is registered and tasks create Pods +3. **Given** an AWS EC2 instance, **When** the cloud adapter starts, **Then** instance identity is verified via IMDSv2 +4. **Given** macOS 13+ hardware, **When** the Apple VF helper starts, **Then** a Linux guest VM boots and executes a workload + +--- + +### User Story 9 — User-Facing: GUI, REST Gateway, Web Dashboard (Priority: P2) + +The Tauri desktop app launches with functional donor, submitter, governance, and settings pages backed by real agent IPC. The REST/HTTP+JSON gateway exposes all 6 gRPC services. The web dashboard provides donor and submitter feature parity with the CLI. + +**Why this priority**: Required for public-facing operation but not for core system validation. + +**Independent Test**: Launch Tauri app → submit job through GUI → verify completion. Call REST endpoint → verify matches CLI output. Load web dashboard → cast governance vote → verify recorded on ledger. + +**Acceptance Scenarios**: + +1. **Given** the Tauri app, **When** launched, **Then** it displays a functional window with donor dashboard +2. **Given** a REST API call to submit a job, **When** the job completes, **Then** the result matches CLI output +3. **Given** the web dashboard, **When** a governance vote is cast, **Then** it is recorded on the tamper-evident ledger + +--- + +### User Story 10 — Operations: Deployment, Energy, Documentation (Priority: P2) + +Docker containers, Helm charts, and release pipelines are functional. Energy metering reports per-node CPU/GPU-time and estimated watts. Documentation includes working quickstart, evidence artifact schema, and incident disclosure policy. + +**Why this priority**: Required for real deployment but not for development testing. + +**Independent Test**: `docker build` → verify minimal image. `docker compose up` → verify 3-node cluster. Follow README quickstart on clean machine → verify it works. Compare RAPL readings against wall-meter on `tensor01.dartmouth.edu`. + +**Acceptance Scenarios**: + +1. **Given** a Dockerfile, **When** built, **Then** the image is under 100MB and runs the agent +2. **Given** docker compose with 3 nodes, **When** started, **Then** they discover each other and form a cluster +3. **Given** a clean machine, **When** following README quickstart, **Then** a working single-node agent is operational within 5 minutes +4. **Given** RAPL-capable hardware, **When** energy metering runs, **Then** estimates are within 20% of real power draw + +--- + +### User Story 11 — Distributed Mesh LLM (Priority: P3) + +GPU donor nodes each run a LLaMA-3-8B model at 4-bit quantization. A distributed router selects K-of-N experts per token. Sparse logit aggregation produces coherent text at 3.2+ tokens/second. The self-prompting loop generates actionable improvement tasks. Action tiers gate operations through governance. A kill switch immediately halts all inference. + +**Why this priority**: The largest single feature, requiring 280+ GPU nodes for distributed operation. Phase 0-1 (centralized model, read-only + suggest tiers) ships first. + +**Independent Test**: Deploy 4+ GPU nodes → register as experts → generate 100 tokens via sparse aggregation → verify coherent output. Trigger kill switch → verify immediate halt. Test self-prompting loop → verify actionable output. + +**Acceptance Scenarios**: + +1. **Given** 4 GPU nodes running LLaMA-3-8B, **When** the router selects K=4 experts, **Then** sparse logit aggregation produces coherent text +2. **Given** K=4 experts at 100ms inter-node latency, **When** generating tokens, **Then** throughput is 3.2+ tokens/second +3. **Given** the governance kill switch, **When** triggered, **Then** all inference streams halt immediately and the last 3 changes are reverted +4. **Given** the self-prompting loop, **When** run for one cycle, **Then** it produces at least one actionable improvement task +5. **Given** a deploy-major action, **When** proposed, **Then** it requires a full governance vote and 24-hour review period + +--- + +### Edge Cases + +- What happens when a donor's internet drops mid-heartbeat?
