 ### Out of Scope
 
-- Network isolation — trusting Claude Code's built-in proxy for domain allowlisting
 - NixOS module form — this is a wrapper script derivation, not a services/programs module
-- Configurable per-project profiles — v1 is one tool set, profiles come later
 - Shareability — personal tool first, not designed for others yet
+- Domain-level network allowlists — tiered isolation (full/internet-only/none) is sufficient for now

+## Current Milestone: v2.0 Network Isolation & Profiles
+
+**Goal:** Add tiered network isolation, per-project instance isolation, named profiles, and host auth passthrough.
+
+**Target features:**
+- Host auth passthrough (read-only mount of auth files from `~/.claude`)
+- Per-project instance isolation (conversation history scoped per project automatically)
+- Named profiles with env vars, mounts, packages, and network tier
+- Nix devshell injection per profile
+- Tiered network: full, internet-only (no LAN/Tailscale), none (offline)

+## Evolution
+
+This document evolves at phase transitions and milestone boundaries.
+
+**After each phase transition** (via `/gsd-transition`):
+1. Requirements invalidated? → Move to Out of Scope with reason
+2. Requirements validated? → Move to Validated with phase reference
+3. New requirements emerged? → Add to Active
+4. Decisions to log? → Add to Key Decisions
+5. "What This Is" still accurate? → Update if drifted
+
+**After each milestone** (via `/gsd-complete-milestone`):
+1. Full review of all sections
+2. Core Value check — still the right priority?
+3. Audit Out of Scope — reasons still valid?
+4. Update Context with current state
