README: add a dedicated Security section (always-on Host/Origin
allowlist & DNS-rebinding defense, cross-site CSRF guard, raw
text/plain parser, WebSocket origin validation, XSS-escaped agent
output), plus an Orchestrator Loop section, Agent Teams, and a
More Features section (self-update, dual-CLI, effort/ultracode,
voice, image, gesture, multi-monitor, CJK). Correct stale stats
(tests 1435->2861, 13->15 route modules, 14->16 types, 9->10
config, server.ts 2697->2254, 9->18 frontend modules), fix the
keyboard-shortcut table to match the actual registry (drop the
unbound Ctrl+Enter/Ctrl+K), repoint a moved doc link, add
Orchestrator + self-update API rows, and add Orchestrator/Team
Watcher to the architecture diagram.
security-architecture.md: document the always-on Host-header &
Origin allowlist, text/plain hardening, WebSocket check, XSS
escaping, and CODEMAN_ALLOWED_HOSTS.
CLAUDE.md: add Host guard / CSRF guard rows + CODEMAN_ALLOWED_HOSTS.
security review report: add a remediation-status banner (the
pre-fix TL;DR now reads as v0.9.4 state; fixed in c669518).

Adds an always-on Host-header allowlist and a cross-site Origin/CSRF guard,
hardens the text/plain body parser, validates the WebSocket upgrade origin,
and escapes AI-derived fields in the subagent panel. Closes the two
CRITICALs and 5 HIGHs from the 2026-06-09 adversarial security review.
- C1: no Host allowlist -> DNS rebinding drove the full API (RCE) on the
default no-auth loopback install. New registerHostGuard rejects rebound
custom domains; allows loopback, any IP literal, the bind host,
*.ts.net / *.trycloudflare.com / *.cfargotunnel.com, the active managed
tunnel, and CODEMAN_ALLOWED_HOSTS.
- C2: a global text/plain parser JSON-parsed every body, enabling cross-site
simple-request CSRF. Parser now keeps the raw string; /api/crash-diag
self-parses; the global Origin guard rejects cross-site state changes.
- H1/H3/H6: self-update, session create/input, and settings/tunnel toggles
were CSRF-triggerable -> now covered by the Origin guard.
- H4: the subagent activity panel injected raw AI tool names/inputs into
innerHTML (executed under CSP 'unsafe-inline'). All sinks now escapeHtml'd.
- H5: the WebSocket upgrade had no Origin/Host check (CSWSH) -> now validated.
A missing Origin is allowed so curl/CLI and Claude Code hooks keep working;
custom reverse-proxy domains need CODEMAN_ALLOWED_HOSTS=host,.suffix.
Deferred: H2 (self-update tag signing, needs signing infra) and CSP
'unsafe-inline' removal (needs a nonce migration).
Tests: test/network-host-guard.test.ts (19), test/routes/ws-routes.test.ts
updated. Report: docs/reports/security-review-2026-06-09.md
