## Context

The security estate acquired overlapping claims to the same responsibility, and
the overlap was invisible in each repository's own documents. `gate-house` was
seeded as a deterministic authority plane — a policy decision point with an
`/authorize` API, grant storage, and a revocation service — while `flex-auth`
already described itself as the authorization control plane and was actively
delivering `FLEX-WP-0017`, an approval contract binding approvals to action,
actor, target, and validity window. Neither repository's INTENT named the other.
`zone-engine` had already been ruled against on the same question.

Full review and evidence: `history/2026-08-28-security-layer-model-and-gate-house-recut.md`.

## Decision requested

Ratify three linked rulings. They are one decision because the second does not
hold without the first, and the third is the first applied to the repository
that was already right.

### Ruling 1 — Adopt the NetKingdom security layer model

The estate is layered **Taxonomy → Tooling → Engines → Staff**, distinguished by
determinism and by the kind of artifact each layer produces. The top layer is
named **Staff** — the general-staff sense of plans and doctrine without
execution — not "Helpers", which undersold a layer holding architecture,
controlling, and change.

The model is published as `net-kingdom/canon/standards/security-layer-model_v0.1.md`,
owned by gate-house, status `proposed`. It belongs in net-kingdom canon rather
than info-tech-canon because it is NetKingdom-flavored security architecture,
not general semantic contract.

It carries two normative rules:

- **Staff never touches Tooling directly. It acts only through Engine APIs.**
- **`access-engine` is the only policy decision point**, generalizing to the
  whole estate the ruling first drawn in `zone-engine/INTENT.md` §5.

### Ruling 2 — Re-cut gate-house as the doctrine council

Gate House is Staff: the council where NetKingdom's security and defence
doctrine is established, documented, taught, and supervised. It holds no
runtime position.

The decisive argument is gate-house's own: **a decision point inside gate-house
would place the deterministic authority boundary inside the non-deterministic
management layer, violating INV-02 — the first invariant the repository exists
to defend.** The repository would have been the clearest available
counterexample to the canon it hosts.

Boundary: *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.*

gate-house keeps what no other repository owns — the operating modes, the
principal/actor/runtime triple, mandates and authority ceilings, the change
dynamics envelope, the MCP doctrine, the posture asymmetry, the assurance
specifications, and the curriculum. It gives up `/authorize`, policy evaluation,
policy engine selection, grant storage, and revocation.

### Ruling 3 — Reframe flex-auth as an Engine and rename it access-engine

`flex-auth` is Engine-layer and remains the only policy decision point. It is
renamed **`access-engine`**. `auth-engine` was rejected: key-cape owns
authentication, and `auth-` preserves the ambiguity the rename exists to remove.
`permission-engine` was rejected as ageing badly against a future `role-engine`.

The name's one cost is that "access" is already spoken for operationally by
ops-warden and ops-mason. It is paid by a demarcation, now normative in §8 of
the standard: **ops-warden and ops-mason own access lanes — how a worker reaches
a host; access-engine owns access rules — whether they may.**

Sequence is binding: **reframe the INTENT first, rename second**, as a governed
migration. The rename touches `FLEX-WP` prefix ownership, State Hub identifiers,
ops-warden's routing tables, zone-engine's binding boundary text, and
secrets-engine integrations.

The reframing also splits a responsibility flex-auth currently holds whole:
**authoring and governing policy is Staff work (gate-house); evaluating it
deterministically and in-path is access-engine's, exclusively.** This is the
constructive resolution of the `FLEX-WP-0017` overlap — gate-house designs the
approval contract, access-engine validates approvals at decision time.

## What approval authorizes

- Publication of the layer model as a proposed net-kingdom standard.
- The gate-house INTENT re-cut, already applied at `7f13f72`.
- The layering review notes placed at the top of twelve estate INTENT files.
- Starting the flex-auth INTENT reframe.
- Retiring the gate-house artifacts that describe an engine: ADR-003 (policy
  engine selection), milestones M0, M3, and M4, and `GH-WP-0001-T04`
  (`/authorize` skeleton). `GH-WP-0001` is rewritten against the re-cut before
  it is promoted to active.

## What approval does not authorize

- The `flex-auth` → `access-engine` rename itself. That is a separate governed
  migration with its own record, and it must not begin before the INTENT
  reframe lands.
- Any change to `zone-engine`'s 2026-08-23 disposition.
- Promoting the standard from `proposed` to `accepted`.
- Any change to another repository's workplans. Work structure stays with the
  repository doing the work.

## Assent still required

Two adaptations move vocabulary away from repositories that currently use it,
and follow the estate's precedent that a boundary is drawn on review by the
other side rather than asserted — as flex-auth did to zone-engine:

1. **flex-auth** — Engine framing, the rename, and the authoring/evaluation split.
2. **kings-guard** and **ops-warden** — releasing "control plane" and the
   security curriculum respectively to the layers that own them.

## Reversal

The rulings are documents; nothing executable depends on them yet, and no code
exists in gate-house. Reversal is reverting the INTENT and standard commits.
The falsifiers that should trigger reconsideration are in
`gate-house/INTENT.md` § "What Would Make This Repository Wrong" — principally
gate-house becoming a paper generator whose conformance loop never turns, or
the estate declining to adopt the authority vocabulary.

rationale: 'Approved as GH-WP-0002-T03. Local-outbox fail-closed is the only remaining
  closed path: if approval-engine cannot insert the outbox row, the revocation does

  for load-bearing approval evidence.'
decided_by: Bernd Worsch
decided_at: '2026-08-29T12:50:58.873684Z'
```

## Context

`GH-IN-0001` (from `audit-core`) required that the revocation failure mode be a
recorded decision rather than an implementation accident. Both sides are
defensible on their own: fail-closed makes an audit dependency into an
availability risk on the revocation path; proceed-with-gap needs a detectable
marker so the gap is visible rather than silent.

v0.5's local-outbox rule already narrowed this. With the queue in
`approval-engine`'s own store, fail-closed triggers only when that store is
down — where the change could not have been recorded anyway — and an
`audit-core` outage does not block a revocation. Satisfying atomicity by
emitting synchronously to `audit-core` inside the mutation is also atomic, and
turns an audit outage into an inability to revoke: the operation least
tolerable to block during an incident.

The statute states the locality rule at §9.4. This record is the decision the
workplan still owed, so an implementer cannot pick the other side by accident.

Wire: `docs/contracts/approval-outbox.md`.

## Decision

**If the local outbox insert cannot commit, the revocation does not commit.**
The same rule applies to issuance, use, and supersession.

**An `audit-core` outage MUST NOT block a revocation.** Drain is asynchronous
and at-least-once. `audit-core` dedupes on `event_id`.

**Synchronous emission to `audit-core` inside the state-change transaction is
forbidden**, even though it is atomic.

Proceed-with-gap is rejected for load-bearing approval evidence. A revocation
that succeeds while its event is lost is the exact case `AUDIT-IN-0001`
conditioned assent on.

## What this authorizes

- `approval-engine` failing a revoke (and any other mutation) when its own
  store cannot insert the outbox row.
- Continuing to revoke while `audit-core` is down, with the row draining later.
- Treating emit-after-commit, a second non-local queue, or a sync `audit-core`
  call inside `BEGIN`…`COMMIT` as out of contract.

## What this does not authorize

- Claiming the outbox closes adversarial omission. Atomicity prevents crash;
  cadence and reconciliation detect suppression after the fact (§9.6).
- A validity query on `audit-core`.
- Any change to another repository's workplans.

## Reversal

Revert this record and the outbox contract. The falsifier is operational: if
failing closed on the local store removes the ability to revoke during the
incidents this engine exists for, the trade needs revisiting — but the
alternative is a silent evidence gap on the event an attacker most wants
missing, which is worse.

decided_by: Bernd Worsch
decided_at: '2026-08-29T12:51:01.355583Z'
```

## Context

Statute §16 left open who marks an approval consumed, and at what point
relative to the decision. `flex-auth` named three failure modes neither engine
closes alone: an ALLOW never consumed; a double consumption by racing callers;
consumption after a failed action. `approval-engine` performs the mutation
because `access-engine` never mutates, and refused to wire a public consume by
guessing the contract. `APPROVAL-WP-0001-T05` and `FLEX-WP-0017-T05` are wait
on this record.

§9.7.3 forbids inferring consumption from a decision record. That stands. The
same paragraph currently reads as if the action must precede the consume call.
That reading cannot enforce single use: two racing PEPs can both act, and CAS
then prevents only the second record.

## Decision

**The PEP-shaped consumer consumes, by compare-and-swap, before the protected
side effect.** The PDP never mutates. Staff never calls consume.

**There is no unconsume and no reserve/release.** An approval authorizes one
attempt, not one success. A consume followed by a failed action spends the
object; retry is a new approval.

**Same `request_digest` against an already-consumed object is idempotent
success** (a retry of one logical request). A different digest is conflict,
and the PEP MUST NOT act.

The three failure modes have owners:

1. *Allow never consumed* — PEP duty to consume; PDP lifetime bounds the
   window; a stale ALLOW without a matching `use` is a finding, not a consume.
2. *Double consumption* — `approval-engine` CAS; the PEP that receives
   conflict does not act.
3. *Consumed then the action fails* — accepted as the cost of closing (2).

Protocol: `docs/contracts/approval-consumption.md`. Statute v0.8 will replace
the §9.7.3 implication that action precedes the consume call; until then this
record governs the blocked implementers.

## What this authorizes

- `approval-engine` exposing `POST /v1/approvals/{id}/consume` against this
  contract, including the digest column the internal CAS does not yet store.
- `FLEX-WP-0017-T05` requiring the PEP (secrets-engine, for that task) to
  consume before the OpenBao call.
- Canon `T-06` consume-side replay (a second, different digest against a
  consumed object) becoming in-scope once the endpoint exists.

## What this does not authorize

- The PDP consuming, or inferring consumption from a decision record.
- Unconsume, reserve, or any path that returns a consumed object to `approved`.
- A consume that is a decision ("may this actor do X").
- Any change to another repository's workplans. Work structure stays with the
  repository doing the work.

## Reversal

Revert this record and the consumption contract. The falsifier is operational:
if spending an approval on a failed attempt makes the estate unable to
complete the actions this object exists for, a reserve/commit protocol can be
raised then. Unconsume is not the alternative — it reopens replay.

state_hub_decision_id: "89c73f45-d07b-40ea-b428-5a7375ce4b09"
```

## Context

Security-layer-model v0.7 §§9.6 and 17 require evidence sources to declare an
expected emission cadence so silence can become a finding. King's Guard is the
only current consumer and drafted `EmissionCadenceDeclaration.md` against the
real `qonto-assistant` source, but correctly declined to keep a Staff-local
schema. The standard left ownership between the two Taxonomy repositories:
`info-tech-canon` for ecosystem-wide semantic contracts and `net-kingdom` for
NetKingdom standards of record.

Treating that as joint ownership would leave version authority ambiguous.
Giving the entire artifact to either repository would instead conflate a
reusable evidence/observability contract with the security obligations of one
estate. The split is therefore made by artifact, with one owner for each.

## Decision

**`info-tech-canon` owns the versioned, ecosystem-wide
`EmissionCadenceDeclaration` semantic contract.** It owns the generic forms,
fields, vocabulary, validation semantics, compatibility rules, and evolution
of the contract.

**`net-kingdom` imports that contract and owns the NetKingdom security
profile.** It owns which evidence classes MUST or SHOULD declare cadence, the
rule that rate monitoring is forbidden for rare load-bearing classes, and the
heartbeat-plus-reconciliation obligations that satisfy security-layer-model
§9.6.

The remaining ownership boundaries are unchanged:

- each source repository owns its declaration instance and emission behavior;
- `kings-guard` owns stream evaluation and silence findings, not the schema;
- Gate House owns doctrine and conformance supervision, not publication or
  runtime behavior.

The King's Guard draft remains the provenance and handover input. Once the
Taxonomy artifacts are published, it becomes historical rather than a second
contract.

## What this authorizes

- Requesting `info-tech-canon` to adopt, revise, or contest the generic
  contract and create its own owning work record.
- Requesting `net-kingdom` to adopt, revise, or contest the security profile
  and create its own owning work record.
- Sources such as `qonto-assistant`, `approval-engine`, and `secrets-engine`
  publishing instances against the eventual canonical contract and profile.
- King's Guard replacing its draft-shaped fixture with the published contract
  without changing its consumer ownership.

## What this does not authorize

- Joint ownership or two independently versioned definitions of the generic
  schema.
- Gate House or King's Guard retaining the schema as a local contract.
- Gate House creating workplans in either Taxonomy repository.
- Treating ownership as source conformance: `qonto-assistant` remains
  incomplete until it publishes and emits the required positive claim.

## Assent and completion

The ownership ruling is resolved. Publication is complete only when both
Taxonomy owners reply in their own voice and publish or explicitly schedule
their respective artifacts. Until then the prior handover residual remains
open, now with an unambiguous requested disposition.

## Reversal

Supersede this record if the generic contract proves inseparable from the
NetKingdom security profile, or if Info Tech Canon cannot provide a stable
cross-domain contract boundary. Reversal must still name one owner for every
artifact; returning to undifferentiated "Taxonomy ownership" is not an
acceptable outcome.

```

## Context

`GH-DEC-2026-003` settled the consumption sequence and named step 1 by endpoint and
by field: `GET /v1/approvals/{id}/claim` → `valid_now` (a fact, not permission).
`approval-engine` serves the approval-claim at that endpoint
(`approval-engine/docs/approval-claim.md`). `secrets-engine`'s PEP validator
(`validate_action_authorization`, `src/secrets_engine/authorization.py`) calls the
same endpoint but expects a flex-auth `ActionAuthorization`. Two different objects
were being assumed on one path, and the divergence would have surfaced at first live
consume rather than at deployment.

`ActionAuthorization` originates in `flex-auth/docs/action-bound-authorization-contract.md`
as a proposed shape for durable approval storage that the same document assigns to
`approval-engine`. It was never ratified, appears nowhere in this repository's
doctrine, and has no `valid_now` field. `GH-DEC-2026-003` was issued after it without
reference to it. There is therefore nothing to reconcile: the claim was the step-1
artifact all along, and this record says so where implementers will find it.

`approval-engine` raised the question rather than guessing, which is the behaviour
§12 asks for. The three substantive assertions in the request were checked here
independently before confirmation.

## Decision

**1. The approval-claim is the step-1 artifact on the `GH-DEC-2026-003` path.**
It carries the approval fact: binding digest, validity window, consumption state,
observation freshness, and issuer. Holding one with `valid_now: true` remains not
authority to act.

**2. `ActionAuthorization` is not required on that path.** `approval-engine` is not
expected to serve it and MUST NOT serve it from the claim endpoint. A step-1 response
cannot contain a step-2 decision; any composed post-decision artifact would be a new
artifact at a new endpoint. The proposal is shelved on this path, not withdrawn.

**3. A PEP validates across the two artifacts it already fetches.** The claim is
checked for the approval fact; the flex-auth `DecisionEnvelope` from step 2 is checked
for exact `CheckRequest` match and policy package/version pin. This is doctrine, not
merely an implementation convenience: **each artifact is validated against the layer
that owns its data.** A PIP republishing the PDP's decision would put a copy of the
authority decision in a repository that did not render it — the same shape of error
the re-cut removed from Gate House itself. No safety property is lost, because
`ActionAuthorization` is a bundle of exactly these two checks.

**4. The `provenance.authority == "state-hub"` requirement is struck.** State Hub is
a read model. It is not the runtime approval authority and never was; flex-auth's own
contract says so. A validator that requires it would fail closed against every
correctly issued claim. `secrets-engine` removes the constant with the validator split.

Consequent changes: `approval-engine` none — the claim schema stands as published;
`secrets-engine` splits its validator and drops the authority constant; `flex-auth`
records that the proposal is shelved on this path. Nothing here gates
`APPROVAL-WP-0002-T03` — `secrets-engine` is fail-closed until its own gates land,
and this record governs first live consume, not deployment.

## Deferred

A ratified post-decision `ActionAuthorization` — one composed, signed, forwardable
object — remains coherent and is recorded here so it is not rediscovered as new. It
is not adopted now because it has no named issuer or lifecycle owner and the sequence
is already settled without one. Revisit on any of: a third or fourth PEP-shaped
consumer; a requirement for a single signed forwardable artifact (offline
verification, or an audit that must replay one object rather than a join); resolution
of flex-auth's open G3 finding by composition rather than by adding a lifetime to the
envelope; or assent of the statute §17 Taxonomy request-claim schema
(`APPROVAL-IN-0001`) — in which case converge there and do **not** revive this
separately.

Also rejected, so they are not re-proposed: serving `ActionAuthorization` at the claim
endpoint (structurally impossible for step 1, and it would assert an authority
`approval-engine` does not hold); and extending the claim with `approvals.required_count`
or `entries` (publishing approver identities is a deliberate least-disclosure non-goal,
and it would still not satisfy the validator).

## Reversal

Revert this record and the amendment to `docs/contracts/approval-consumption.md`. The
falsifier is a demonstrated check that two-artifact validation cannot perform and a
single composed artifact can — most plausibly offline or forwarded verification with
no access to the PDP. That is a trigger for the deferred option above, not for
returning `ActionAuthorization` to the claim endpoint, which stays forbidden on
structural grounds regardless.

```

## Context

`security-layer-model` v0.7 §13 holds the open-gap register and §13.1 the PEP
stance-map register. Both were created because the obligations above them named a
register that did not exist — §9.1's own logic, that a requirement whose register is
missing is a capability catalogued without a surface. They did their job.

`maturity-engine` (MAT-WP-0001) now holds both as queryable data: the §13 snapshot
with state and owner-status intact, the §13.1 inventory, `ASM-0`…`ASM-6` registered
as data owned by gate-house, `pep-stance-publication` owned by ops-warden, and
blocked-clean scored equal to conforming by test. It proposes that the statute table
become a pointer.

Four repositories are waiting behind the answer. `user-engine` and `tenant-engine`
have published stance maps and asked for §13.1 rows; ops-warden is published and
ops-mason is not. §6.4 obliges every PEP-shaped consumer to publish and obliges those
maps to be inventoried. Each week the question stays open, the register either
accumulates transcription or accumulates silence.

## Decision

**§13 and §13.1 become pointers to `maturity-engine`, and not before it publishes a
committed, versioned export of both registers that is readable without a live query.**

Two things are true at once and the ruling holds both.

**A statute should not carry state.** §13 and §13.1 change without the doctrine
changing. A table maintained by hand inside a standard of record drifts, and every
row transcribed into it is the manual step `maturity-engine` exists to remove. This
is the same rule as `GH-DEC-2026-005`: the artifact is held by the layer that owns
its data, and a repository that neither computes nor owns a fact should not be its
register of record.

**A standard must be readable on its own.** A pointer to a live engine is not a
register an auditor can read; it is an instruction to run software. Whatever else the
statute is, it must be legible in git, at a version, to a reader with no cluster
access — including a reader auditing the estate precisely because they do not trust
its running systems. Replacing a drifting table with an unreadable reference trades a
known defect for a worse one.

The condition reconciles them. `maturity-engine` computes and remembers; it also
publishes the result as a committed artifact at a stated path and version, and the
statute cites that path. The rows are then computed rather than transcribed, and
still readable without a query. **Publication is the migration's precondition, not
its follow-up.**

### What happens meanwhile

The tables stay, and rows continue to be transcribed into §13.1 at each version cut.
No repository waits on the export to get an answer. `user-engine`, `tenant-engine`,
ops-warden and ops-mason are inventoried in v0.8 whether or not the export has
landed by then.

This is deliberately the slower path. The alternative — strike the tables now and
point at the engine — would close four open requests immediately and leave the
statute stating an obligation whose register no reader can open, which is the exact
defect §13.1 was created to fix. Repeating a defect in the other direction is not
progress.

### What is asked of `maturity-engine`

Not a new capability, a published form of one it has. The export must be a file in
the repository, versioned, generated rather than hand-edited, carrying the same
fields the statute tables carry today (§13: capability, kind, declarer, owner, state,
owner-status; §13.1: consumer, stance map path, shape), and regenerable so drift
between the export and the engine's own state is detectable. `layer.yaml` and
`pep-stance.yaml` are the shape to follow: published, machine-readable, and asserted
equal to shipped behaviour by a test. §6.4 obligation 3 already requires that
equality of every PEP; a register of those maps should not hold itself to less.

When it exists, the §13 and §13.1 tables are replaced by a citation of it, and
`maturity-engine` becomes the register of record.

## Reversal

Revert to tables if the export proves to drift from the engine's computed state
faster than a hand-maintained table drifted from reality — that is, if generation and
publication decouple. The falsifier is mechanical: a regeneration that changes the
committed export without any underlying evidence having changed, or an underlying
change that does not reach the export.
