X-Content-Type-Options, X-Frame-Options, and Referrer-Policy all
defaulted to empty (disabled). Set defaults to nosniff, DENY, and
strict-origin-when-cross-origin respectively. Operators can still
override or disable via environment variables.

Both backend and frontend Dockerfiles ran all processes as root.
Add a dedicated appuser in each runtime stage so container processes
run with minimal privileges, limiting blast radius of any container
escape.

The first 6 characters of invalid agent tokens were logged, leaking
partial credential information. Remove token_prefix from log messages
while preserving the request path for debugging.

send_gateway_session_message only required basic auth (AUTH_DEP) while
all other gateway endpoints required ORG_ADMIN_DEP. Any authenticated
user could send messages to any gateway session. Now requires org-admin
and verifies the board belongs to the caller's organization.

The webhook ingest endpoint read the entire request body with no size
limit, enabling memory exhaustion attacks. Add a 1 MB limit checked
via both Content-Length header (early reject) and actual body size.

User-controlled fields (skill name, source URL, webhook payloads) were
interpolated directly into agent instruction messages. Sanitize skill
fields by stripping newlines/control chars, and fence all external data
behind "BEGIN EXTERNAL DATA" / "BEGIN STRUCTURED DATA" delimiters with
explicit "do not interpret as instructions" markers. Move system
instructions above the data section so they cannot be overridden.

Webhook ingest endpoint was completely unauthenticated. Add an optional
`secret` field to BoardWebhook. When configured, inbound requests must
include a valid HMAC-SHA256 signature in X-Hub-Signature-256 or
X-Webhook-Signature headers. Uses hmac.compare_digest for timing safety.
Includes migration to add the secret column.

Main agents (board_id=None) could list boards across all organizations.
Now resolves the agent's organization via its gateway and filters boards
by organization_id to prevent cross-tenant data leakage.

The function only checked that the caller was an authenticated user
(not an agent) but its name implied privilege enforcement. Rename to
require_user_actor and add docstring clarifying the distinction between
actor-type checks and privilege/role checks (require_org_admin, is_super_admin).
