Firecracker API Socket (#13) + +### Current State +- `src/sandbox/firecracker.rs`: + - **Line 227–228**: Process spawning works (launches `firecracker --api-sock`), captures PID. But no HTTP calls to the API socket. + - **Line 274**: Snapshot creation writes file placeholders instead of calling `PUT /snapshot/create`. + - **Lines 101–120**: Rootfs preparation is stubbed (writes placeholder file). + - **Lines 123–152**: Network config is stubbed (logs only). + - API socket path defined at line 58 (`work_dir/firecracker.sock`). + +### Decision +Use hyper (already available via reqwest dependency) or a lightweight Unix socket HTTP client to issue PUT requests to the Firecracker API socket. Sequence: /machine-config → /boot-source → /drives/rootfs → /network-interfaces/eth0 → /actions InstanceStart. + +### Rationale +Firecracker uses a REST API over Unix domain socket. The protocol is simple HTTP PUT with JSON bodies. hyper with unix socket support is the standard Rust approach. + +### Alternatives Considered +- **Raw TCP over UDS**: Too low-level; would need to implement HTTP framing manually. +- **reqwest with unix socket**: reqwest doesn't natively support UDS; would need a custom connector. hyper is simpler for this use case. + +--- + +## 3. Apple Virtualization.framework FFI (#14) + +### Current State +- `src/sandbox/apple_vf.rs`: + - **Line 138**: `start()` — logs but TODOs Swift FFI bridge for VZVirtualMachineConfiguration. + - **Line 154**: `freeze()` — TODOs VZVirtualMachine.pause() FFI. + - **Line 173**: `checkpoint()` — writes "vm-state-placeholder" instead of calling saveMachineStateTo(). + - **Line 191**: `terminate()` — TODOs VZVirtualMachine.stop() FFI. + +### Decision +Build a Swift helper binary (`wc-apple-vf-helper`) invoked via subprocess. The helper accepts JSON commands on stdin and returns JSON results on stdout. Commands: create, start, pause, resume, stop, checkpoint. + +### Rationale +Direct Objective-C FFI from Rust (via objc2 crate) is fragile, requires unsafe code (violating project conventions), and is hard to test. A subprocess helper is code-signed independently (Principle I), testable in isolation, and avoids unsafe blocks entirely. + +### Alternatives Considered +- **objc2 crate**: Requires unsafe code, complex lifecycle management. Rejected per zero-unsafe-code policy. +- **C bridging header**: Same unsafe issues as objc2 with extra build complexity. + +--- + +## 4. WASM Module Loading (#15) + +### Current State +- `src/sandbox/wasm.rs`: + - **Line 35**: `create()` — logs CID but skips module fetch and compilation. + - **Line 43**: `start()` — sets running flag but TODOs instantiation and stdout capture. + - **Line 106**: `run_module()` — returns empty `Vec::new()`, no actual WASM execution. + +### Decision +Implement: (1) fetch WASM bytes from CID store via existing `data_plane::cid_store`, (2) compile with `wasmtime::Module::new()`, (3) instantiate with `wasmtime::Instance::new()`, (4) call exported `_start` or specified entry function, (5) capture stdout via WASI preview1. + +### Rationale +wasmtime 27 is already in Cargo.toml. The WASI preview1 API provides standard stdout/stderr capture. CID store integration follows the existing data_plane patterns. + +### Alternatives Considered +- **wasmer**: Not already in dependencies; wasmtime is the project's chosen WASM runtime. + +--- + +## 5. Ed25519 Signature Verification (#16) + +### Current State +- `src/policy/rules.rs` **line 60–61**: `check_signature()` rejects only empty or all-zero 64-byte signatures. Any other 64-byte value passes. Comment references T018 Phase 2. + +### Decision +Replace with `ed25519_dalek::VerifyingKey::from_bytes(&ctx.submitter_public_key)` → `verifying_key.verify(&message, &signature)`. The message is the manifest hash. The public key comes from the submitter's registered identity. + +### Rationale +ed25519-dalek 2 is already in Cargo.toml. The API is straightforward: construct VerifyingKey, call verify(). No new dependencies needed. + +### Alternatives Considered +- **ring**: Also viable but ed25519-dalek is already a dependency and provides a cleaner API for Ed25519 specifically. + +--- + +## 6. TPM2/SEV-SNP/TDX Certificate Chain Validation (#17) + +### Current State +- `src/verification/attestation.rs`: + - **Lines 392–398**: `verify_quote_signature()` uses crude binding check — first 4 bytes of signature must match first 4 bytes of SHA-256(signed_data). Not real crypto. + - **Lines 401–424**: `verify_tpm2()`, `verify_sev_snp()`, `verify_tdx()` perform structural parsing (magic bytes, length, field presence) then delegate to the stubbed signature check. + - **Implemented**: Measurement registry (known-good PCR/measurement values), quote structure parsing, empty/zero rejection, agent version rollover. + - **Missing**: Actual cryptographic signature verification, CA certificate chain validation. + +### Decision +Implement a `CertificateChainValidator` trait with platform-specific implementations: +- **TPM2**: Parse EK certificate, verify AIK signature against EK, verify quote signature against AIK. +- **SEV-SNP**: Fetch/bundle AMD ARK → ASK → VCEK chain. Verify VCEK signs the attestation report. +- **TDX**: Use Intel DCAP verification library or implement ECDSA chain validation against Intel's root CA. + +Bundle known root CA certificates as compile-time constants. Provide runtime refresh via vendor API as fallback. + +### Rationale +Certificate chain validation is the core of hardware attestation. Bundled CAs enable offline verification (faster, no network dependency). Runtime fetch handles CA rotation. + +### Alternatives Considered +- **Vendor-hosted verification services**: Adds network dependency to the critical trust path. Rejected for offline-first approach. +- **openssl crate**: Heavy dependency. Prefer pure-Rust x509 parsing (x509-parser crate or webpki). + +--- + +## 7. Apple Secure Enclave DeviceCheck (#18) + +### Current State +- `src/verification/attestation.rs` **lines 426–442**: `verify_apple_se()` checks only payload length ≥ 64 bytes and last 64 bytes non-trivial. No Apple API call. + +### Decision +Implement HTTP POST to Apple's App Attest validation endpoint. The attestation object (CBOR-encoded) is sent to Apple's server which returns a verified assertion or error. + +### Rationale +Apple Secure Enclave attestation cannot be verified locally — it requires Apple's server to validate the device identity. This is by design (Apple controls the root of trust). + +### Alternatives Considered +- **Local verification**: Not possible for Apple SE. Apple's server is the only authority. + +--- + +## 8. BrightID HTTP Client (#19) + +### Current State +- `src/identity/personhood.rs` **line 103**: `ureq_get_brightid()` returns `Err("HTTP client not yet integrated")`. +- `BrightIdVerification` struct exists with `verified`, `unique`, `context_id`, `error` fields (deserializable from JSON). +- `PersonhoodResult` enum: Verified, Pending{connections_needed}, Failed(String), ProviderUnavailable(String). + +### Decision +Add reqwest as an async HTTP client. Implement `GET /node/v6/verifications/WorldCompute/{contextId}` call. Parse JSON response into existing `BrightIdVerification` struct. Map to `PersonhoodResult`. + +### Rationale +reqwest is async and tokio-native (project already uses tokio). The BrightID API is a simple GET endpoint. The data model already exists. + +### Alternatives Considered +- **ureq**: Sync-only; would block the tokio runtime. The stub even mentions ureq but async is better for a P2P daemon. + +### New Dependency +`reqwest = { version = "0.12", features = ["json", "rustls-tls"] }` — needed by 5+ stubs (#18–#22). Use rustls-tls to avoid native openssl dependency. + +--- + +## 9. OAuth2 Provider Adapters (#20) + +### Current State +- `src/identity/oauth2.rs` **line 27**: `verify_oauth2()` returns `ProviderUnavailable("OAuth2 verification flows not yet implemented")`. +- `OAuth2Result` enum: Verified{provider, account_id}, Failed(String), ProviderUnavailable(String). + +### Decision +Implement authorization code flow for each provider: +1. Generate authorization URL with provider-specific scopes +2. Handle callback with authorization code +3. Exchange code for access token via provider's token endpoint +4. Fetch user profile to get account_id +5. Return OAuth2Result::Verified + +Provider config (client_id, client_secret, redirect_uri) loaded from environment variables. + +### Rationale +Standard OAuth2 authorization code flow. Each provider follows the same pattern with different endpoint URLs and scopes. + +### Alternatives Considered +- **oauth2 crate**: Provides OAuth2 flow abstractions. Worth adding to avoid reimplementing token exchange. Decision: use `oauth2 = "4"` crate. + +### New Dependency +`oauth2 = "4"` — standard Rust OAuth2 client library. + +--- + +## 10. Phone/SMS Verification (#21) + +### Current State +- `src/identity/phone.rs`: + - **Line 18**: `send_verification_code()` returns error. + - **Line 25**: `verify_code()` returns error. +- `PhoneResult` enum: Verified{phone_hash}, CodeExpired, InvalidCode, ProviderUnavailable(String). + +### Decision +Implement Twilio Verify API integration: +1. `send_verification_code()`: POST to Twilio Verify to send SMS/voice code. +2. `verify_code()`: POST to Twilio Verify to check code. +Provider abstracted behind a trait for future provider swap. + +### Rationale +Twilio Verify is the most widely used SMS verification API. Trait abstraction allows swapping to Vonage or another provider later. + +### Alternatives Considered +- **Vonage**: Viable alternative. Trait abstraction makes this swappable. +- **AWS SNS**: More complex setup. Twilio is simpler for SMS verification. + +--- + +## 11. Sigstore Rekor Integration (#22) + +### Current State +- `src/registry/transparency.rs` **line 60**: Returns `TransparencyLogResult::Unavailable` with placeholder message. +- `src/ledger/transparency.rs` **lines 28–44**: Creates fake entry ID from hash prefix (`stub-rekor-{hex_prefix}`). Verify function always returns `Ok(true)`. + +### Decision +Implement HTTP POST to `https://rekor.sigstore.dev/api/v1/log/entries` with hashedrekord entry type. Parse response for log index, entry UUID, and inclusion proof. Verify function checks inclusion proof against Rekor's signed tree head. + +### Rationale +Rekor's REST API is well-documented. The hashedrekord type is the simplest entry format — just a hash and signature. Public instance available for development; private instance for production. + +### Alternatives Considered +- **sigstore-rs crate**: Provides Rust bindings. Decision: evaluate maturity; if insufficient, use raw reqwest calls. + +--- + +## 12. OpenTelemetry OTLP Exporter (#23) + +### Current State +- `src/telemetry/mod.rs` **line 20**: Ignores `otel_endpoint` parameter (`let _ = otel_endpoint`). Only initializes JSON logging via tracing-subscriber. + +### Decision +When `otel_endpoint` is Some: +1. Create OTLP trace exporter via `opentelemetry_otlp::new_exporter().tonic()` +2. Create trace pipeline with batch span processor +3. Add tracing-opentelemetry layer to the subscriber +4. Register metrics exporter for runtime metrics + +All OTLP dependencies are already in Cargo.toml. + +### Rationale +The dependencies (opentelemetry 0.27, opentelemetry-otlp 0.27, tracing-opentelemetry 0.28) are already declared. This is purely wiring code. + +### Alternatives Considered +None — the technology choice was already made when dependencies were added to Cargo.toml. + +--- + +## 13. Raft Consensus (#24) + +### Current State +- `src/scheduler/coordinator.rs`: + - **Line 55**: `start_election()` increments term, sets Candidate role. No RPC broadcasting. + - **Line 64**: `become_leader()` sets Leader role. No heartbeat sending or log replication. + +### Decision +Implement openraft's `RaftStorage` and `RaftNetworkFactory` traits for coordinator state: +1. `RaftStorage`: In-memory log with optional write-ahead log (WAL) file. +2. `RaftNetworkFactory`: Use existing libp2p gossipsub for Raft RPC transport. +3. Wire `Raft::new()` into coordinator startup. +4. Replace stub election/leader with openraft's built-in leader election. + +### Rationale +openraft 0.9 is already in Cargo.toml. It provides a complete Raft implementation — just needs storage and network adapters. + +### Alternatives Considered +- **Custom Raft**: Reimplementing Raft is error-prone. openraft is well-tested. +- **etcd**: External dependency; too heavy for an embedded coordinator. + +--- + +## 14. NAT Detection (#25) + +### Current State +- `src/network/nat.rs` **line 35**: Returns hardcoded `NatStatus::Direct`. Comment notes real detection needs AutoNAT and STUN. + +### Decision +Implement STUN binding request (RFC 5389) to determine external address and NAT type. Use libp2p's built-in AutoNAT behavior for ongoing NAT status updates. + +### Rationale +libp2p already includes AutoNAT support. For initial bootstrap (before peers are available), a STUN binding request to public servers (Google, Cloudflare) provides the external address. + +### New Dependency +`stun_client` or use raw UDP with STUN message parsing. Evaluate `stun-rs` crate. + +### Alternatives Considered +- **libp2p AutoNAT only**: Requires existing peers; doesn't work at bootstrap. STUN supplements it. + +--- + +## 15. DNS Seed Nodes (#26) + +### Current State +- `src/network/discovery.rs` **line 63**: `DiscoveryConfig::default()` populates bootstrap seeds with placeholder `/dnsaddr/bootstrap1.worldcompute.org`. + +### Decision +Replace placeholder addresses with real World Compute DNS seed hostnames once domain is registered. For now, make the seed list configurable via config file or environment variable, with the placeholder as fallback. + +### Rationale +DNS seeds cannot be implemented until the domain and seed infrastructure exist. Making the list configurable allows deployment without code changes. + +### Alternatives Considered +- **Hardcoded IPs**: Fragile; DNS names are preferred for infrastructure flexibility. +- **DHT-only bootstrap**: Requires at least one known peer. DNS seeds solve the initial bootstrap problem. + +--- + +## Summary of New Dependencies + +| Dependency | Version | Purpose | Used By | +|-|-|-|-| +| reqwest | 0.12 (rustls-tls, json) | Async HTTP client | BrightID, OAuth2, Rekor, Apple DeviceCheck, Twilio | +| oauth2 | 4 | OAuth2 authorization code flow | OAuth2 adapters (#20) | +| x509-parser | 0.16 | Certificate chain parsing | TPM2/SEV-SNP/TDX validation (#17) | +| stun-rs or equivalent | latest | STUN binding requests | NAT detection (#25) | + +**No new dependency needed for**: CLI wiring, WASM loading, Ed25519, OTLP, Raft consensus, DNS seeds, Firecracker API. diff --git a/specs/003-stub-replacement/spec.md b/specs/003-stub-replacement/spec.md new file mode 100644 index 0000000..f10752b --- /dev/null +++ b/specs/003-stub-replacement/spec.md @@ -0,0 +1,228 @@ +# Feature Specification: Replace Implementation Stubs with Real Functionality + +**Feature Branch**: `003-stub-replacement` +**Created**: 2026-04-16 +**Status**: Draft +**Input**: User description: "Address issue #7 and all sub-issues (#8–#26): replace all implementation stubs with real functionality across CLI, sandbox, attestation, identity, infrastructure, and network modules." + +## User Scenarios & Testing *(mandatory)* + +### User Story 1 - Donor Operates via CLI (Priority: P1) + +A volunteer donor launches the World Compute CLI to join the network, check their status, pause/resume contribution, view earned credits, and read logs — all from a single terminal session. + +**Why this priority**: The CLI is the primary user-facing entry point. Without functional CLI commands, no other feature can be exercised by end users. All five command groups (donor, job, cluster, governance, admin) are currently inert. + +**Independent Test**: Can be fully tested by running each CLI subcommand (e.g., `worldcompute donor join`, `worldcompute job submit`) and verifying it dispatches to the correct module and returns meaningful output. + +**Acceptance Scenarios**: + +1. **Given** a compiled binary, **When** a user runs `worldcompute donor join --resource-cap 50%`, **Then** the agent lifecycle module initializes and the user sees confirmation of enrollment. +2. **Given** a running donor agent, **When** a user runs `worldcompute donor status`, **Then** the system displays current resource usage, trust score, and credit balance. +3. **Given** a compiled binary, **When** a user runs `worldcompute job submit manifest.yaml`, **Then** the job is validated, dispatched, and the user receives a job ID. +4. **Given** a running cluster, **When** a user runs `worldcompute cluster status`, **Then** peer count, ledger head, and cluster health are displayed. +5. **Given** appropriate governance role, **When** a user runs `worldcompute governance propose "Increase NCU cap"`, **Then** a proposal is created and broadcast to voters. +6. **Given** OnCallResponder role, **When** a user runs `worldcompute admin halt`, **Then** the system triggers an emergency halt with audit trail. + +--- + +### User Story 2 - Submitter Runs a Sandboxed Workload (Priority: P1) + +A job submitter sends a workload that gets assigned to a donor node. The donor's sandbox (Firecracker on Linux, Apple VF on macOS, or WASM for lightweight tasks) boots a real VM or runtime, loads the workload from the CID store, executes it in isolation, and enforces egress rules. + +**Why this priority**: Sandboxed execution is the core value proposition. Without real VM/WASM lifecycle, the system cannot run any workloads. + +**Independent Test**: Can be tested by submitting a sample workload and observing that a sandbox starts, executes, and terminates — producing output artifacts. + +**Acceptance Scenarios**: + +1. **Given** a Linux donor with Firecracker installed, **When** a workload is assigned, **Then** a microVM boots with the correct kernel, rootfs, and resource limits. +2. **Given** a macOS donor, **When** a workload is assigned, **Then** an Apple Virtualization.framework VM starts with the correct configuration. +3. **Given** a WASM-eligible workload, **When** assigned to any donor, **Then** the WASM module is fetched from the CID store, compiled via wasmtime, and executed with sandbox constraints. + +--- + +### User Story 3 - Platform Verifies Donor Hardware Integrity (Priority: P2) + +When a donor enrolls or is re-evaluated, the platform verifies their hardware attestation — validating the full certificate chain for TPM2, AMD SEV-SNP, Intel TDX, or Apple Secure Enclave — to assign an accurate trust score. + +**Why this priority**: Trust scores gate what workloads a donor can run. Without real certificate-chain validation, trust scoring relies on structural checks only — sufficient for testing but not for production security guarantees. + +**Independent Test**: Can be tested by presenting known-good and known-bad attestation quotes and verifying correct accept/reject decisions with full chain validation. + +**Acceptance Scenarios**: + +1. **Given** a donor with a valid TPM2 endorsement key chain, **When** attestation is verified, **Then** the full EK→AIK→quote chain is validated and trust score reflects hardware-backed integrity. +2. **Given** a donor with AMD SEV-SNP, **When** attestation is verified, **Then** the ARK→ASK→VCEK chain is validated against AMD's root certificates. +3. **Given** a donor presenting an Apple Secure Enclave attestation, **When** verified, **Then** the DeviceCheck/App Attest API confirms the device's authenticity. +4. **Given** a policy-engine signature check, **When** a manifest is submitted, **Then** Ed25519 signatures are verified against the submitter's registered public key (not just structural checks). + +--- + +### User Story 4 - Donor Proves Personhood and Links Identity (Priority: P2) + +A new donor verifies their identity through BrightID (primary), OAuth2 providers, or phone verification to earn humanity points and participate in governance. + +**Why this priority**: Identity verification gates governance participation and HP-weighted voting. Without real provider integrations, no user can complete enrollment beyond structural stubs. + +**Independent Test**: Can be tested by initiating a BrightID verification flow and confirming the HTTP call to BrightID's API returns a valid verification status. + +**Acceptance Scenarios**: + +1. **Given** a donor with a BrightID account, **When** they verify via WorldCompute context, **Then** the system calls BrightID's verification API and records the result. +2. **Given** a donor choosing OAuth2 login, **When** they select GitHub as provider, **Then** a real authorization code flow completes and links their identity. +3. **Given** a donor choosing phone verification, **When** they submit their phone number, **Then** an SMS code is sent via the configured provider and can be verified. + +--- + +### User Story 5 - Platform Anchors Decisions to Transparency Logs (Priority: P3) + +Policy decisions and artifact signatures are recorded in an immutable transparency log (Sigstore Rekor) so that any participant can audit the history of approvals, deployments, and governance actions. + +**Why this priority**: Transparency anchoring is essential for trust but does not block core compute operations. It can be added after the compute pipeline is functional. + +**Independent Test**: Can be tested by submitting a transparency log entry to Rekor's API and verifying it appears in the log. + +**Acceptance Scenarios**: + +1. **Given** an artifact signature event, **When** the registry records it, **Then** a Rekor log entry is created via the REST API and a receipt is returned. +2. **Given** a policy decision, **When** the ledger anchors it, **Then** the decision hash is recorded in the transparency log with a verifiable timestamp. + +--- + +### User Story 6 - Operators Monitor System Health (Priority: P3) + +Cluster operators configure an OpenTelemetry endpoint and receive traces and metrics from all nodes, enabling observability dashboards and alerting. + +**Why this priority**: Observability supports operations but is not required for core functionality. + +**Independent Test**: Can be tested by configuring an OTLP endpoint and verifying that traces and metrics are exported. + +**Acceptance Scenarios**: + +1. **Given** `otel_endpoint` is configured, **When** the telemetry module initializes, **Then** traces and metrics are exported to the configured OTLP endpoint. + +--- + +### User Story 7 - Coordinators Achieve Consensus (Priority: P3) + +Multiple coordinator nodes elect a leader and replicate the scheduling log via Raft consensus, ensuring the cluster survives coordinator failures without losing job state. + +**Why this priority**: Consensus is critical for multi-coordinator deployments but single-coordinator mode works for initial testing. + +**Independent Test**: Can be tested by starting multiple coordinator instances and verifying leader election and log replication. + +**Acceptance Scenarios**: + +1. **Given** three coordinator nodes, **When** they start, **Then** a leader is elected via openraft within the configured timeout. +2. **Given** a leader coordinator fails, **When** the failure is detected, **Then** a new leader is elected and scheduling resumes. + +--- + +### User Story 8 - Nodes Discover Peers on the Network (Priority: P3) + +Donor and coordinator nodes discover each other through DNS seed nodes and detect their NAT topology to establish connectivity. + +**Why this priority**: Network discovery bootstraps the mesh but mDNS already provides local discovery for development. + +**Independent Test**: Can be tested by resolving DNS seed addresses and verifying peer records are returned; NAT detection can be tested with a STUN server. + +**Acceptance Scenarios**: + +1. **Given** a new node starting, **When** it queries DNS seeds, **Then** it receives a list of bootstrap peer addresses to connect to. +2. **Given** a node behind a NAT, **When** NAT detection runs, **Then** the correct NAT type (Direct, FullCone, RestrictedCone, PortRestricted, Symmetric, or Unknown) is identified via STUN. + +--- + +### Edge Cases + +- What happens when a BrightID node is unreachable during verification? The system should return a clear error and allow retry, not silently pass or permanently fail. +- What happens when Firecracker is not installed on a Linux donor? The sandbox should report the missing dependency and mark the donor as WASM-only capable. +- What happens when an OAuth2 provider revokes app credentials? The system should fail gracefully with an actionable error message and not crash. +- What happens when the Rekor transparency log is temporarily unavailable? Policy decisions should still proceed but flag the anchoring as pending, with retry. +- What happens when a WASM module in the CID store is corrupted? The module should fail compilation with a clear error and the task should be rescheduled. +- What happens when all coordinator nodes fail simultaneously? The system should detect the condition and refuse new job submissions until a coordinator recovers. +- What happens when DNS seed nodes return stale peer addresses? The node should attempt connection, detect failure, and fall back to mDNS or cached peers. +- What happens when provider credentials (OAuth2, BrightID, Twilio, Apple) expire mid-operation? The current operation fails with a clear error message indicating credential expiry. The agent must be restarted with updated credentials; no hot-reload. +- What happens when Firecracker API socket returns an error during VM setup (invalid kernel, insufficient resources)? The system fails immediately, marks the donor as incompatible for this workload class, and reschedules the task to another donor. Maximum 3 donors attempted per task — after 3 failures the task is marked as failed with a clear error listing all attempted donors and their failure reasons. + +## Requirements *(mandatory)* + +### Functional Requirements + +**CLI Wiring (Issues #8–#12)** +- **FR-001**: System MUST dispatch all donor CLI subcommands (join, status, pause, resume, leave, credits, logs) to the agent lifecycle module. +- **FR-002**: System MUST dispatch all job CLI subcommands (submit, status, results, cancel, list) to the scheduler module. +- **FR-003**: System MUST dispatch all cluster CLI subcommands (status, peers, ledger-head) to the network/ledger modules. +- **FR-004**: System MUST dispatch all governance CLI subcommands (propose, list, vote, report) to the governance module. +- **FR-005**: System MUST dispatch all admin CLI subcommands (halt, resume, ban, audit) to the admin service, enforcing OnCallResponder role requirements. + +**Sandbox VM Lifecycle (Issues #13–#15)** +- **FR-006**: System MUST configure and start a Firecracker microVM via the API socket, including machine config, boot source, drives, network interfaces, and instance start. +- **FR-006a**: When a Firecracker VM configuration fails, the system MUST mark the donor as incompatible for that workload class and reschedule to another donor, with a maximum of 3 donor attempts per task before marking the task as failed. +- **FR-007**: System MUST start, pause, stop, and save Apple Virtualization.framework VMs via a Swift FFI bridge or helper binary. +- **FR-008**: System MUST fetch WASM modules from the CID store, compile them via wasmtime, and execute them within sandbox constraints. + +**Attestation & Crypto (Issues #16–#18)** +- **FR-009**: System MUST perform real Ed25519 signature verification against registered public keys in the policy engine, replacing structural-only checks. +- **FR-010**: System MUST validate the full certificate chain for TPM2 (EK chain), AMD SEV-SNP (ARK→ASK→VCEK), and Intel TDX (DCAP) attestation quotes. +- **FR-011**: System MUST verify Apple Secure Enclave attestation via Apple's DeviceCheck/App Attest API. + +**Identity & Verification (Issues #19–#21)** +- **FR-012**: System MUST call BrightID's verification API via HTTP to check a donor's personhood status in the WorldCompute context and record the result. +- **FR-013**: System MUST implement real OAuth2 authorization code flows for email, GitHub, Google, and Twitter providers. +- **FR-014**: System MUST send and verify SMS/voice codes via a phone verification provider. + +**Infrastructure (Issues #22–#24)** +- **FR-015**: System MUST submit transparency log entries to Sigstore Rekor's REST API and return verifiable receipts. +- **FR-016**: System MUST export traces and metrics to a configured OTLP endpoint when `otel_endpoint` is set. +- **FR-017**: System MUST implement Raft leader election and log replication via openraft for coordinator consensus. + +**Network (Issues #25–#26)** +- **FR-018**: System MUST detect NAT topology using STUN-based probing, replacing the stub that always returns Direct. +- **FR-019**: System MUST resolve DNS seed node addresses for bootstrap peer discovery, replacing placeholder values. + +### Key Entities + +- **DonorAgent**: Represents a volunteer node's lifecycle state, resource caps, trust score, and credit balance. +- **Sandbox**: An isolated execution environment (Firecracker VM, Apple VF VM, or WASM runtime) with enforced resource and egress constraints. +- **AttestationQuote**: A hardware-backed integrity proof with a certificate chain linking to a platform root of trust. +- **IdentityVerification**: A record of a donor's proof-of-personhood or identity linkage via BrightID, OAuth2, or phone. +- **TransparencyEntry**: An immutable log record of a policy decision or artifact signature, anchored in Sigstore Rekor. +- **CoordinatorState**: A Raft-replicated state machine tracking job scheduling, leader election, and log replication. + +## Success Criteria *(mandatory)* + +### Measurable Outcomes + +- **SC-001**: All 5 CLI command groups (donor, job, cluster, governance, admin) accept and dispatch every defined subcommand, with no "not yet implemented" messages remaining. +- **SC-002**: A sample workload submitted via CLI completes end-to-end through sandbox execution and returns results within 60 seconds on each supported platform. +- **SC-003**: Hardware attestation verification correctly accepts valid certificate chains and rejects invalid/expired chains with 100% accuracy on test vectors. +- **SC-004**: At least one identity verification path (BrightID, OAuth2, or phone) completes a full end-to-end flow from user initiation to recorded verification. +- **SC-005**: Transparency log entries are retrievable from Sigstore Rekor after submission, with verifiable timestamps and receipts. +- **SC-006**: Telemetry data (traces and metrics) appears at a configured OTLP endpoint within 30 seconds of system activity. +- **SC-007**: A 3-node coordinator cluster completes leader election and survives a single-node failure without losing scheduled jobs. +- **SC-008**: NAT detection correctly identifies at least 3 NAT types (direct, full cone, symmetric) when tested against known network configurations. +- **SC-009**: DNS seed resolution returns valid peer addresses and nodes successfully bootstrap from them. +- **SC-010**: All existing tests continue to pass after stub replacement, plus new integration tests cover each replaced stub — zero regressions. + +## Clarifications + +### Session 2026-04-16 + +- Q: What end-to-end completion target defines success for a minimal test workload? → A: Under 60 seconds on each supported platform. +- Q: What happens when provider credentials (OAuth2, BrightID, Twilio) expire or are rotated mid-operation? → A: Fail the current operation with a clear error; require agent restart for new credentials. +- Q: What happens when Firecracker API socket returns an error during VM configuration? → A: Fail immediately, mark donor as incompatible for this workload, reschedule to another donor. + +## Assumptions + +- Firecracker binary, guest kernel, and rootfs images are available on the host or fetchable from the CID store. Firecracker testing requires a Linux environment with KVM support. +- Apple Virtualization.framework testing requires macOS 12+ on Apple Silicon or supported Intel Macs. +- BrightID's verification API (v6) remains stable and the WorldCompute context is registered. +- OAuth2 provider app credentials (client ID, client secret) are configured via environment variables or a secrets manager — not hardcoded. +- Phone/SMS verification requires a funded account with the chosen provider (e.g., Twilio). Testing will use the provider's sandbox/test mode. +- Sigstore Rekor's public instance (rekor.sigstore.dev) is used for development; production may use a private instance. +- AMD, Intel, and Apple root certificates for attestation chain validation are available as bundled trust anchors or fetched from vendor APIs. +- The existing 422 tests serve as a regression baseline — no test may be removed or weakened to accommodate stub replacement. +- Single-coordinator mode remains functional as a fallback when Raft consensus is not configured. +- DNS seed domain names will be registered and configured before the network bootstrap feature is deployed. diff --git a/specs/003-stub-replacement/tasks.md b/specs/003-stub-replacement/tasks.md new file mode 100644 index 0000000..af4c8cc --- /dev/null +++ b/specs/003-stub-replacement/tasks.md @@ -0,0 +1,324 @@ +# Tasks: Replace Implementation Stubs + +**Input**: Design documents from `/specs/003-stub-replacement/` +**Prerequisites**: plan.md, spec.md, research.md, data-model.md, contracts/ + +## Format: `[ID] [P?] [Story] Description` + +- **[P]**: Can run in parallel (different files, no dependencies) +- **[Story]**: Which user story this task belongs to (e.g., US1, US2) +- Exact file paths included in all descriptions + +--- + +## Phase 1: Setup (Shared Infrastructure) + +**Purpose**: Add new dependencies and shared utilities needed by multiple user stories + +- [x] T001 Add reqwest dependency to Cargo.toml: `reqwest = { version = "0.12", features = ["json", "rustls-tls"] }` +- [x] T002 Add oauth2 dependency to Cargo.toml: `oauth2 = "4"` +- [x] T003 Add x509-parser dependency to Cargo.toml: `x509-parser = "0.16"` +- [x] T004 Verify build succeeds with new dependencies: `cargo build --lib` + +--- + +## Phase 2: Foundational — CLI Dispatch (Blocking Prerequisites) + +**Purpose**: Wire all CLI subcommands into main.rs.
