# Security layer model v0.8 amendment set

## Goal

Land the queued amendments to security-layer-model as v0.8: the §9.7.3 consume-ordering protocol clarification, the §11 emission-guarantee declaration check, the §13/§13.1 register disposition against maturity-engine, the §9.5 posture/maturity recomputability boundary, and the GH-DEC-2026-005 split-validation doctrine. Each is currently doctrine held in a gate-house contract or decision rather than in the accepted statute.

**Normative text for A1–A6 is drafted at
`docs/amendments/v0.8-amendment-set.md`.** That file is the reviewable unit: each
amendment carries its own wording, defect statement, and authority, so it can be
argued before anything touches a cut document. T06 assembles from it.

## Why now

`security-layer-model_v0.7.md` is accepted and must not be patched in place. Since
its acceptance, five separate rulings have been made that belong in the statute and
are currently held in gate-house contracts, decision records, or a reply in another
repository's inbox. Each was correctly kept out of v0.7; together they are now a
version.

The risk of leaving them scattered is not that any one is wrong — each was argued
where it was made. It is that a reader of the accepted statute gets an answer that
the estate no longer holds, and that the register sections (§13, §13.1) are
accumulating rows in a document that four repositories have said should be a
pointer.

Gate House authors the amendment set. `net-kingdom` publishes. Nothing here edits
v0.7.

```

**§9.7.3 — consume ordering.** v0.7 reads as if the protected action must precede
the consume call. `GH-DEC-2026-003` and `docs/contracts/approval-consumption.md`
establish the opposite: the PEP MUST obtain a successful consume before the side
effect, because act-then-consume lets CAS prevent only the second *record* and not
the second *side effect*. Carry the clarification into §9.7.3 without retracting the
forensic claim that consumption MUST NOT be inferred from a decision record.

```

**§11 — emission-guarantee declaration check.** Add the conformance check drafted as
the last section of `docs/contracts/approval-emission-detection.md`: a load-bearing
evidence source declares a local outbox plus heartbeat-or-reconciliation; an
attributive non-atomic source declares the trade and does not claim completeness.
This exists so the next engine catalogued as an evidence source cannot reintroduce
the `GH-IN-0001` gap silently.

```

**§13 and §13.1 — register disposition.** `maturity-engine` (MAT-WP-0001) holds the
§13 gap-register snapshot and the §13.1 stance-map inventory as queryable data, with
`ASM-0`…`ASM-6` registered as data owned by gate-house and `pep-stance-publication`
owned by ops-warden. Four repositories have offered §13.1 rows —
`user-engine/pep-stance.yaml`, `tenant-engine/pep-stance.yaml`, ops-warden published,
ops-mason unpublished.

Decide whether §13 becomes a pointer to `maturity-engine` or stays a table. The
argument for the pointer is that a hand-maintained table in a statute is a register
that drifts, and that transcribing rows is exactly the manual step the engine exists
to remove. The argument against is that a statute must be readable without a live
query. Both are real; settle it as a decision record rather than by editing.

Settled as `GH-DEC-2026-006`: the registers become pointers, and not before
`maturity-engine` publishes a committed, versioned export readable without a live
query. Publication is the precondition, not the follow-up. Until it lands the tables
stay and rows are transcribed, so the four outstanding stance-map offers are
inventoried in v0.8 either way — `user-engine`, `tenant-engine`, `ops-warden`
(published) and `ops-mason` (unpublished).

```

**§9.5 — the posture/maturity boundary.** `kings-guard` (KG-DEC-2026-002,
`kings-guard/docs/PostureMaturityBoundary.md`) argues that the discriminator is
recomputability, not volatility: given the same criteria and the same evidence, if
you MUST get the same answer it is maturity and belongs in an engine; if you CANNOT
promise the same answer it is posture and belongs in Staff. The argument is that
volatility describes the two things without partitioning them, and every case it does
not obviously cover becomes an argument at exactly the boundary §6 says must not be
open to argument.

Disposed as `GH-DEC-2026-007`: **adopted**, with one added clause. Recomputability
is assessed over the stated criteria, so a criterion that dereferences a judgment
("level 2 iff the reviewer marked it adequate") is deterministic in form and
inferential in substance. A criterion MUST therefore bottom out in evidence about the
subject, not in another party's conclusion about it. All three kings-guard
consequences are carried, including the constraint they volunteered against
themselves — capability readiness MUST NOT be an input to posture — and their honest
limit, that "the same evidence" is undefined until §17, is recorded in the statute
beside the test rather than left in the commentary.

```

**Split validation as statute.** `GH-DEC-2026-005` states that a PEP validates each
artifact against the layer that owns its data and that a PIP MUST NOT republish the
PDP's decision. That is a general property of the layer model, not a fact about the
approval path, and it currently lives only in a decision record and a contract.
Place it in the statute where §8's three-way split is stated.

```

**Assemble, circulate, publish.** Cut `security-layer-model_v0.8.md`, circulate for
assent as v0.6 and v0.7 were, and hand to `net-kingdom` for publication. Record
dispositions of the returned findings. v0.7 stays accepted and unedited until v0.8
is accepted in its place.

```

**§17 — refresh the ownership paragraph.** §17 closes with "Ownership is proposed,
not assigned… Neither has assented." `GH-DEC-2026-004` assigned the split and both
`info-tech-canon` (`ITC-WP-0018`, `ITC-EMISSION-CADENCE 0.1` in canon 0.7.0) and
`net-kingdom` (`NK-WP-0035`, `emission-cadence-security-profile_v0.1.md`) have
accepted in their own voice. Replace the paragraph with the settled ownership and
cite the decision; keep §17's drafter credit to `kings-guard`.

Surfaced by `docs/conformance/2026-09-06-v06-findings-audit.md`, which also confirms
that all fifteen v0.6 review findings are dispositioned in v0.7 — this is the one
paragraph a later decision made stale, not a missed finding.

**Derived summaries must be marked (A7).** Four instances in one week, in four
repositories, of a repository acting on a derived summary rather than the
authoritative body — a stale revisit trigger here, a change log read for section text
here, a dual-control rule written against an assumed schema in `access-engine`, a
fixture read for contract prose in `secrets-engine`. Proposed by `approval-engine` on
the observation that at four instances it is a property of how the estate publishes
rather than four separate lapses: authoritative bodies with derived summaries beside
them and no staleness marker on the derivatives.

Drafted as A7 — a §11 marking obligation on the publisher and a §12 paragraph on the
consumer. The limit is stated in the draft: marking makes staleness visible, it does
not detect a marked derivative that is still wrong.
