Safety hardening — red team response (issue #4)#6
Merged
Conversation
Independent evaluation of red team findings via 5 parallel research agents. Adopts valid safety concerns (attestation stubs, egress enforcement, governance separation) while preserving constitutional identity as volunteer compute federation. Rejects recommendations requiring constitutional amendment (institutional SSO, excluding personal hardware). Artifacts: spec, plan, research, data-model, contracts, tasks (108 tasks, 7 phases, 10 phases total including setup/polish). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
New modules: policy/ (engine, rules, decision), incident/ (containment, audit), identity/ (oauth2, phone, personhood), registry/ (artifacts, transparency), sandbox/egress, governance/roles. 257 tests pass. Policy engine implements 8-step pipeline wrapping validate_manifest(). Governance roles enforce separation of duties with 90-day default expiration. Egress module blocks RFC1918/link-local/metadata. Incident containment requires OnCallResponder role. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- DonorId: strongly-typed with enforced format "wc-donor-{hex16}" derived
from Ed25519 public key hash per FR-S072

- Format validation: rejects invalid prefix, wrong length, non-hex chars
- Lifecycle enrollment now derives DonorId from signing key, not opaque string

Summary
Comprehensive safety hardening addressing the red team review in #4. Independent evaluation of the review's claims found ~40% were mischaracterized or already addressed; the remaining valid concerns are fully implemented.
validate_manifest()— identity, signature, artifact registry, workload class, quota, egress allowlist, data classification, ban checks. LLM advisory is non-authoritative.Key architectural decision
The project's constitutional identity as a volunteer compute federation is preserved. The red team's recommendation to convert to an institution-only model was evaluated and rejected — safety is achieved through VM isolation, cryptographic attestation, and deterministic policy enforcement, not through excluding hardware classes or requiring institutional affiliation.
