New policy-loader.mjs reads .llm-security/policy.json with deep-merge against
defaults that exactly match existing hardcoded values. Integrated into all 7 hooks:
- pre-prompt-inject-scan: injection.mode (env var still takes precedence)
- post-session-guard: trifecta.mode, window_size, long_horizon_window
- pre-edit-secrets: secrets.additional_patterns
- pre-bash-destructive: destructive.additional_blocked
- pre-write-pathguard: pathguard.additional_protected
- pre-install-supply-chain: supply_chain.additional_blocked_packages
- post-mcp-verify: mcp.volume_threshold_bytes, mcp.trusted_servers
Backward compatible: no policy file = identical behavior to v5.1.0.

New audit-trail.mjs writes structured events to LLM_SECURITY_AUDIT_LOG path.
Integrated into post-session-guard at 6 warning emission points: trifecta,
escalation-after-input, data flow, volume threshold, slow-burn, behavioral drift.
No-op when env var not set — zero overhead for existing users.

All 6 plugin READMEs now use identical installation section:
marketplace-first approach with /plugin browsing, then direct
settings.json as alternative. Replaces inconsistent mix of
git clone, plugin add, and JSON-only instructions.

Initial addition of ms-ai-architect plugin to the open-source marketplace.
Private content excluded: orchestrator/ (Linear tooling), docs/utredning/
(client investigation), generated test reports and PDF export script.
skill-gen tooling moved from orchestrator/ to scripts/skill-gen/.
Security scan: WARNING (risk 20/100) — no secrets, no injection found.
False positive fixed: added gitleaks:allow to Python variable reference
in output-validation-grounding-verification.md line 109.

Harden git clone attack surface for remote scans with defense-in-depth:
Layer 1 (all platforms): 8 git config flags disable hooks, symlinks,
filter/smudge drivers, fsmonitor, local file protocol. 4 env vars
isolate from system/user git config and block interactive prompts.
Layer 2 (OS sandbox): macOS sandbox-exec and Linux bubblewrap (bwrap)
restrict file writes to only the specific temp directory. bwrap
probe-tests availability before use. Graceful fallback on Windows
and Ubuntu 24.04+ (git config hardening only).
Additional: post-clone 100MB size check, UUID-unique evidence filenames,
evidence file cleanup, cleanup guarantee in scan/plugin-audit commands.
32 new tests (1147 total).
