Forward-looking planning doc capturing prior-art analysis from OLP's Phase 7 PR-B re-evaluation, scoped down to OCP's single-provider (anthropic) deployment. Documents: - Multi-tenant gap for OCP (cross-key lateral read, OAuth exposure) - Why OLP's outer-bwrap PR-B approach is the wrong path to copy (Anthropic design intent, ~/.claude.json upstream not-planned) - Three viable alternatives: A. Ephemeral $HOME via env var (~50 LOC, recommended Phase 1) B. bwrap --tmpfs $HOME + ro-bind credentials (apt dep, Linux only) C. OverlayFS lowerdir+upperdir (needs CAP_SYS_ADMIN) - Orthogonal cross-key isolation layer (per-spawn customConfig denyRead or per-OS-user spawning) - Trust-tier framing (single-user / family-zone / shared-host) Not an ADR — becomes one only when work actually starts. Not binding; ALIGNMENT.md authority requirements still apply when sandbox code lands. Cross-references OLP's parallel multi-provider work at dtzp555-max/olp ADR 0014 Amendment 1 (pending) and archive branch phase-7-pr-b-outer-bwrap-snapshot.
