Gate House

The council where NetKingdom's security and defence doctrine is established, documented, taught, and supervised.

Gate House is a NetKingdom Staff-layer repository and the home of the Active Secrets Management (ASM) Canon. It is the headquarters of the operational staff that does the chores of IT security in NetKingdom.

A word about the name, because it argues the other way. A gate house sounds like the thing requests pass through. It is not. In a real castle the gate house is where the guard is quartered, the watch is set, and the porter's rules are posted — the rules of entry are decided there, and the gate itself is held by someone else.

Gate House does not stand in the gate. It decides what the gate is for, who may be asked to open it, and how we know it held.

Its artifacts are specifications, decisions, workplans, and tasks. It holds no runtime position, renders no authorization decision, and stores no state that anything depends on at runtime.

Where it sits

NetKingdom's IT security is layered by determinism and by the kind of artifact each layer produces — see net-kingdom/canon/standards/security-layer-model_v0.7.md.

Taxonomy   cross-cutting language          info-tech-canon, net-kingdom canon
Tooling    deterministic state             key-cape (authelia, lldap, privacy-idea), OpenBao
Engines    deterministic APIs              user / tenant / zone / secrets / access-engine
Staff      interactive, non-deterministic  gate-house, ops-mason, ops-warden,
                                           kings-guard, whitehat-security

Read by determinism, those layers reproduce the Canon's three planes — which is the point:

Cognition proposes. Authority disposes. Infrastructure executes.

The rule that binds every repository:

Staff never touches Tooling directly. It acts only through Engine APIs.

Why Gate House is not the decision point

Gate House was seeded as a deterministic authority plane — an /authorize API, grant storage, a revocation service. That was withdrawn on its own argument:

A decision point inside Gate House would place the deterministic authority boundary inside the non-deterministic management layer, violating INV-02, "No Privilege from Cognition" — the first invariant this repository exists to defend.

NetKingdom already has a policy decision point: access-engine (currently flex-auth). It stays the only one. Gate House writes the doctrine that decision point implements, and checks that it did.

The boundary, in one line:

The mandate and the operating mode are Gate House's. The decision is access-engine's. The credential is secrets-engine's. The perimeter is ops-mason's and ops-warden's.

What Gate House owns

• The doctrine — the ASM Canon, its invariants, and the argument behind them. Invariants graduate into net-kingdom/canon/standards/.
• The authority context — principal, actor, runtime identity, tenant, environment, mandate, task, operating mode. Defined here, consumed by access-engine as input claims.
• The agentic operating modes — assistant and autonomous as distinct security regimes.
• Mandates, authority ceilings, and kill switches for autonomous actors, as a model and a governance obligation.
• The Change Dynamics Envelope — how much change the organization tolerates.
• The MCP doctrine — tool availability is not permission.
• The posture contract with kings-guard, including its asymmetry.
• Conformance review — whether authority in practice matches the declared mandate and ceiling.
• The assurance specifications T-01…T-10, executed by whitehat-security.
• The security curriculum.

What Gate House does not own

The authorization decision or any /authorize surface; policy engines, packages, or rollout; grants, credentials, leases, or revocation; identity, tenancy, zone, or user lifecycle; secret storage or PKI; anomaly detection or threat intelligence; access lanes, SSH certificates, or host hardening; deployment or remediation execution; and other repositories' workplans.

Component	Layer	Responsibility
info-tech-canon	Taxonomy	ecosystem-wide semantic contracts
net-kingdom	Taxonomy	NetKingdom standards of record
key-cape	Tooling	packaged identity tooling; IAM profile; authentication
OpenBao	Tooling	secret storage, leases, PKI
user-engine	Engine	users, accounts, memberships
tenant-engine	Engine	tenant-as-an-entity facts
zone-engine	Engine	zone identity and membership
secrets-engine	Engine	credential abstraction, custody, lifecycle
access-engine	Engine	the decision — the only decision point
gate-house	Staff	doctrine, authority context, conformance, curriculum
ops-mason	Staff	builds and tears down access routes and perimeters
ops-warden	Staff	operational access lanes, stewardship, runbooks
kings-guard	Staff	adaptive defence, observation, containment
whitehat-security	Staff	offensive validation

Two words that must not drift: ops-warden and ops-mason own access lanes — how a worker reaches a host. access-engine owns access rules — whether they may.

The doctrine in seventeen lines

1. No privilege from cognition.
2. Every privileged action crosses a deterministic authority boundary.
3. Tool availability is not permission.
4. Principal and actor remain distinguishable.
5. Assistant and autonomous operation are different security modes.
6. Autonomous agents use independent identities and explicit mandates.
7. Authority is least-privileged, scoped, and time-bounded.
8. Delegation attenuates.
9. Security posture may reduce authority but must not expand it.
10. Emergency revocation works without agent cooperation.
11. Agents do not casually modify the policies defining their own ceiling.
12. Credentials are ephemeral implementation artifacts of authorization.
13. Audit evidence is protected from the actor being audited.
14. Failure of critical policy or authorization dependencies fails closed.
15. Production guarantees must survive incorrect agent behavior.
16. Where one appearance is reachable by two routes, the record says which route.
17. A transitional deviation is admissible only where it fails closed on the case that distinguishes it from the conformant state.

The last two are September 2026 and are repository-level, not estate doctrine. 16 is why an unknown and an absent stance cell must be told apart in the record even though both fail closed, and why a decision envelope that looks authentic is not therefore attributable. 17 is why one request for transitional relief was granted and another declined in the same week. See INTENT.md § Core Rules.

Agentic operating modes

The distinction Gate House exists to keep sharp.

Assistant — a human is engaged and can redirect or stop at human latency. The human remains the principal; the agent remains a visible actor. A human disconnecting must never silently promote the session into autonomous privileged operation.

Autonomous — a scheduled or triggered agent acts without supervision, and therefore requires unique identity, a named owner, an explicit mandate, an authority ceiling, runtime and concurrency limits, budgets, an independent kill switch, and audit reconstruction.

The conformance loop

Doctrine that no engine implements is fiction. Gate House is only real if this turns:

gate-house asserts an invariant
      → the engines implement it
      → whitehat-security tries to break it
      → kings-guard observes it in operation
      → findings return to gate-house as doctrine change

Agents decide what to attempt. Engines decide what may cross the boundary. Gate House decides what the boundary is for.
