 ## Project Overview
 
-World Compute is a decentralized, volunteer-built compute federation. The codebase is a Rust workspace with 94+ source files, 489+ passing tests, and 20 library modules. All 5 CLI command groups are functional (donor, job, cluster, governance, admin). Core modules implemented: WASM sandbox with CID store integration, real Ed25519 signature verification, certificate chain validation (TPM2/SEV-SNP/TDX), BrightID/OAuth2/phone identity verification, Sigstore Rekor transparency logging, OTLP telemetry, STUN-based NAT detection, Raft coordinator consensus, and Firecracker/Apple VF sandbox drivers.

Production P2P daemon with full libp2p NAT-traversal stack (TCP + QUIC, Noise, mDNS + Kademlia DHT, identify, ping, AutoNAT, Relay v2 server+client, DCUtR) and distributed job dispatch (TaskOffer + TaskDispatch request-response with CBOR + real WASM execution) — validated end-to-end in-process via `tests/nat_traversal.rs`.

-## Remaining Stubs
-
-Most of the original 76 stubs replaced (issue #7, branch 003-stub-replacement). Remaining:
-- **Egress allowlist**: Endpoint allowlist field in JobManifest (egress is default-deny, correct behavior)
-- **Artifact registry lookup**: Full CID lookup against ApprovedArtifact registry (structural gate in place)
-- **Apple VF helper binary**: Swift helper (`wc-apple-vf-helper`) needs separate macOS compilation
-- **Full Merkle proof verification**: Rekor inclusion proof (format validation in place)
+## Remaining Stubs and Placeholders
+
+Zero TODO comments in src/ and zero `#[ignore]` tests remain. However, several subsystems have scaffolding landed but placeholders in critical paths — these are not production-ready and are tracked in open issues:
+
+- **Mesh LLM** (#27, #54): `src/agent/mesh_llm/expert.rs::load_model()` is a placeholder — no real LLaMA inference. Orchestration (router, aggregator, safety tiers, kill switch) is complete.
+- **AMD / Intel root CA fingerprints** (#28): pinned as `[0u8; 32]` in `src/verification/attestation.rs`. Validators enter permissive bypass mode when fingerprints are zero.
+- **Rekor public key** (#29): pinned as `[0u8; 32]` in `src/ledger/transparency.rs`. Signed tree head verification is skipped when the key is zero.
+- **Agent lifecycle → gossip wiring** (#30): heartbeat/pause/withdraw return payloads but don't broadcast over gossipsub (the daemon event loop does broadcast separately).
+- **Firecracker rootfs** (#33): concatenates layer bytes; does NOT run mkfs.ext4 + OCI tar extraction. A real boot would fail.
+- **Admin `ban()`** (#34): `src/governance/admin_service.rs::ban()` returns `Ok(())` without updating the trust registry.
+- **Platform adapters** (#37, #38, #39): Slurm/K8s/Cloud scaffolds exist but have not been exercised against live systems.
+- **GUI** (#40): never built or run.
+- **Deployment** (#41): Dockerfile and Helm chart exist but have never been built or deployed.
+- **REST gateway** (#43): routing + auth + rate-limit logic exist but no HTTP listener is bound in the daemon.
+- **Churn simulator** (#51): statistical model, not a real kill-rejoin harness.
+- **Apple VF Swift helper** (#52): never built on macOS.
+- **Receipt verification** (`src/verification/receipt.rs`): structural check only; coordinator public key not yet wired.
+- **Daemon `current_load()`** (`src/agent/daemon.rs:500`): stub returning 0.1.
+- **Cross-machine firewall traversal** (#60): production NAT stack validated in-process only. Real WAN operation behind institutional firewalls is unverified.

 ## Recent Changes
 
+- **004-full-implementation** (2026-04-18): Merged scaffolding + significant implementation for #57 and its sub-issues (#28–#56, and a first pass on #27/#54 mesh LLM). 802 tests passing across Linux/macOS/Windows + Sandbox KVM + swtpm CI. Landed: full production P2P daemon with libp2p NAT-traversal stack (TCP + QUIC + Noise + mDNS + Kademlia + identify + ping + AutoNAT + Relay v2 server/client + DCUtR), AutoRelay reservations, public libp2p bootstrap relays as default rendezvous, TaskOffer + TaskDispatch request-response protocols over CBOR, real WASM execution of dispatched jobs, `worldcompute job submit --executor <multiaddr> --workload <wasm>` CLI command, end-to-end 3-node relay-circuit integration test. Also landed: ~12 sub-issues fully completed (policy engine, GPU passthrough, adversarial tests, test coverage, credit decay, preemption, confidential compute, mTLS, energy metering, storage GC, documentation, scheduler matchmaking); ~16 sub-issues partially addressed with scaffolding (see Remaining Stubs above); #27/#54 mesh LLM orchestration shell complete but real LLaMA inference deferred. Critical open issue #60 tracks cross-machine WAN mesh formation behind firewalls.
 - **003-stub-replacement** (2026-04-16): Replaced all implementation stubs (#7, #8–#26). 77 tasks, 489+ tests. Added reqwest, oauth2, x509-parser, rcgen dependencies. Wired CLI, sandboxes, attestation, identity, transparency, telemetry, consensus, network.
 - **002-safety-hardening** (2026-04-16): Red team review (#4). Policy engine, attestation, governance, incident response, egress, identity hardening. 110 tasks, PR #6.
-- **001-world-compute-core** (2026-04-15): Initial architecture and implementation across 11 phases.

-> - Library crate with 422 passing tests covering safety-critical paths
-> - Deterministic policy engine (10-step evaluation pipeline)

-> - Governance separation of duties, quorum thresholds, time-locks
-> - Network egress blocking (RFC1918, link-local, cloud metadata)
-> - Incident response containment primitives with audit trails
-> - CI on Linux/macOS/Windows via GitHub Actions

+> - Distributed job dispatch: TaskOffer and TaskDispatch request-response protocols over CBOR. Real WASM execution on the executor. `worldcompute job submit --executor <multiaddr> --workload <wasm>` CLI command for end-to-end remote dispatch.
+> - All 5 CLI command groups functional
+> - WASM sandbox with CID-store integration and real workload execution (wasmtime)
+> - Deterministic 10-step policy engine with artifact registry + egress allowlist
+> - Preemption supervisor with SIGSTOP via nix (measured and logged)
+> - BrightID / OAuth2 / phone identity verification
+> - Scheduler with ClassAd matchmaking + R=3 disjoint-AS placement
+> - All 8 adversarial test scenarios implemented
+> - Confidential compute: AES-256-GCM + X25519 key wrapping
+> - mTLS certificate lifecycle via rcgen + Ed25519 auth tokens
+> - Credit decay with 45-day half-life + anti-hoarding
+> - Storage GC + acceptable-use filter + shard residency enforcement
+> - Energy metering via Intel RAPL
