# Layer declarations: the estate-wide view of flex-auth's boundaries review

flex-auth published `docs/conformance/boundaries-review.md` (FLEX-WP-0030) on
2026-09-20 and corrected its first finding on 2026-09-21. It surveyed twelve
security-relevant counterparts against §11 of the security layer model
(`net-kingdom/canon/standards/security-layer-model_v0.8.md`, proposed). Each of
the five engine repositories received a tailored message; none of them sees the
whole set. This record holds the cross-repo view and adds two findings the
review could not have reached from inside one repository.

## What the review established

**B1 (as corrected) — precedence between two permitted forms.** §11 accepts a
`layer:` key in `INTENT.md` frontmatter *or* an equivalent declaration file, and
does not say which governs when a repository carries both. Nine repositories
carry both and disagree in every case: `INTENT.md` capitalises, `layer.yaml`
does not. A conformance run reading one file and a run reading the other reach
different answers for nine repositories, and both follow §11. Two rulings are
needed: which form governs, and whether the §3 vocabulary is case-sensitive.

The first published B1 claimed the estate spelled `layer:` three ways *across*
repositories. It was produced by a shell pipeline that took the first match per
repository across two files without recording which file it came from. flex-auth
rebuilt it as `tools/survey_layer_declarations.go` with a receipt, and running it
falsified the finding it was built to reproduce. The correction is the stronger
result: the disagreement is *within* each repository and universal rather than
careless.

**B2 — four security-relevant repositories carry no `layer:` key**: gate-house,
key-cape, ops-mason, net-kingdom.

**B3 — an emission guarantee nobody has claimed.** §11 requires every repository
catalogued in §4 as a source of evidence to declare class, cadence and detection
surface, and says a source declaring none is not conforming. flex-auth produces
the decision record and declares none. Whether it is a §4 source, or only the
producer of an artifact audit-core is the source of, is unruled. flex-auth has
declined to take the reading that favours it and holds the gap open as G2.

**B4 — whether a layer declaration should carry a standard version.** flex-auth
removed `0.7` from its own and enforced the absence by test: assent is to a
boundary at a named version, not to current text, so a version in the declaration
makes every revision read as though it invalidated the declaration.

**B5 — canon names `access-engine`; the repository still answers to `flex-auth`**
and the rename (FLEX-WP-0020) has not landed.

## Two findings the review could not see

The review surveyed the twelve counterparts flex-auth has boundaries with. An
estate-wide sweep of every repository carrying a declaration finds fourteen, and
the three it did not cover change two of its conclusions.

**One repository declares a value outside the §3 vocabulary — not two.**
`informed-decision` declares `surface`, which appears nowhere in the model as a
layer. `railiance-master` declares `Taxonomy`, and **`Taxonomy` is §3's first
enumerated layer**, defined in §3.1, carried in §4's catalog, mapped in §7 and
given its own §17. The custodian's first reading of this finding was wrong: it
took flex-auth's validator set `{Staff, Engine, Tooling}` for the §3 vocabulary.
§3 enumerates four layers — Taxonomy, Tooling, Engines, Staff. The correction is
railiance-master's, with the citations, and it is recorded here rather than
quietly amended because the first version was circulated to gate-house.

What remains of the finding is sharper and is aimed at the validator and the
standard, not at the declaring repositories:

- **flex-auth's validator omits §3.1 and misspells §3.3.** It admits `Engine`
  where §3's table writes `Engines`, and omits `Taxonomy` altogether. Its set
  looks built from §4's role-typed catalog rows rather than from §3.
- **§3 and §4 disagree inside the standard.** §3's table says `Engines`; §4's
  catalog types eight rows `Engine`. A conformance run built from §3 and one
  built from §4 disagree about every engine repository in the estate. That is
  the same defect as B1 — two readings of one standard, both faithful — one
  level further in, and B1's precedence ruling does not reach it.
- **`railiance-master`'s casing matches §3's table exactly.** Against the
  standard's own spelling, the nine lower-casing `layer.yaml` files are the
  divergent ones, which bears on whether case sensitivity is even the question.

`informed-decision`'s `surface` is a genuinely separate case and does not
behave like `railiance-master`'s. The two should not be ruled on together.

**The "two generators, two conventions" reading does not hold estate-wide.**
Nine of nine is true of the repositories flex-auth surveyed, but
`informed-decision` and `railiance-master` agree between their two files. The
split tracks the vocabulary values, not the generators: exactly the repositories
whose value is outside the vocabulary are the ones written by hand and
internally consistent. This does not weaken B1 — precedence is still unruled —
but it removes the inference that a single generator pair explains the estate,
and with it the hope that one generator fix closes the finding.

`whitehat-security` declares `Staff` in `INTENT.md` and has no `layer.yaml`,
which is flex-auth's own shape: a second repository that cannot exhibit the
split for the same reason.

## Where the questions sit

| # | Question | Owner |
|---|---|---|
| 1 | Which §11 form governs when both are present | gate-house |
| 2 | Is the §3 vocabulary case-sensitive | gate-house |
| 3 | Is §3's vocabulary closed — `surface` only; `Taxonomy` is §3.1 | gate-house |
| 4 | gate-house's own layer declaration (B2) | gate-house |
| 5 | Is flex-auth a §4 source of evidence (B3) | gate-house |
| 6 | May a declaration carry a standard version (B4) | gate-house |
| 7 | Which side of the B3 line audit-core holds | audit-core |
| 8 | What `CheckRequest.tenant` denotes on the write API — ANSWERED, TEN-DEC-2026-002 | tenant-engine |
| 9 | Layer declarations for key-cape, ops-mason, net-kingdom (B2) | each owner |

gate-house holds six of the nine, including the ruling that decides whether
flex-auth is non-conformant on its own conformance record today. That
concentration is not an accident of routing: every one of them is a question
about what §11 means, and gate-house authors §11. It is also the repository
flex-auth names as the clearest B2 case — a doctrine owner that has not
discharged its own obligation.

audit-core can state its side of B3 without waiting for anyone, but stating it
does not close G2: flex-auth holds the gap open until gate-house rules *and*
audit-core confirms.

tenant-engine's is the longest-running — asked 2026-09-15, re-asked 2026-09-20,
still unanswered — and the only one of the nine blocking implementation rather
than documentation. FLEX-WP-0022-T02 waits on it by choice: flex-auth can read
`FlexAuthWriteAuthorizer.authorize` copying `tenant_id` onto both
`CheckRequest.tenant` and `resource.id`, and has declined to encode a policy rule
from reading a consumer's code. "None of the nine write actions is refused
cross-tenant" is a complete answer; silence is not, because a deliberate
cross-tenant scope and an omitted rule are indistinguishable in the published
package.

## The custodian's reading

The v0.8 assent round should not close while §11's own mechanical check is
ambiguous. Six of the nine questions are §11 interpretation, and a standard that
cannot tell two conforming conformance runs to agree is not yet mechanically
checkable in the sense §11 claims for itself. gate-house has already been asked
to hold v0.8 over audit-core's §11 review; these belong in the same hold rather
than in a follow-on amendment.

None of this is the custodian's to rule. §11 is net-kingdom canon authored by
gate-house, and the custodian's contribution is the estate-wide survey and the
observation that the questions concentrate in one repository.

## Correction, 2026-09-21

The first version of this record claimed two repositories declared values
outside §3's vocabulary. `Taxonomy` is in §3. The error was the custodian's and
was made in the same shape as the one flex-auth had just corrected: a survey run
against an artifact that stands in for the standard — there, a shell pipeline;
here, another repository's validator — and published without reading §3 itself.
A tenth question follows from the correction: whether §3's `Engines` or §4's
`Engine` governs a declaration.

## Resolution, 2026-09-21

gate-house ruled all six of its questions the same day, in `GH-DEC-2026-017`
(declaration form), `GH-DEC-2026-018` (B3) and `GH-DEC-2026-019` (the v0.8
hold), with the canon changes drafted as gate-house amendments A9–A13 and
circulated for assent. No net-kingdom file was edited; publication stays with
net-kingdom.

- **Precedence.** `INTENT.md` governs; a `layer.yaml` is a derived artifact that
  must agree. Precedence alone would have made eight of the nine disagreements
  invisible rather than settled, so a disagreement between the two forms stays
  a reportable finding.
- **Case.** Case-insensitive, ASCII fold, §4's column spelling canonical. No
  repository re-spells anything; flex-auth's validator changes, as it offered.
- **Vocabulary.** Closed at four tokens, not three. The validator's omission of
  `Taxonomy` is the defect; `railiance-master` is conforming. `surface` is the
  only genuine off-vocabulary value.
- **Scope.** §11 binds §4, and both off-vocabulary repositories sit outside §4 —
  so neither is a non-conformance, and **a conformance run must now state its
  scope**. That rule reaches this record: the sweep below was published without
  stating that it ranged over every repository carrying a declaration rather
  than over §4, and two of its three findings turned on repositories §11 does
  not bind.
- **B2.** Discharged for gate-house in the same commit: `INTENT.md` frontmatter,
  `layer: Staff`, no sidecar. The prose `**Layer:** Staff` line had stood since
  v0.1 and is exactly what gate-house's own paragraph says does not count.
- **B3.** Ruled against flex-auth: a custodian is never the source of what it
  holds, so flex-auth is a §4 source, owes an emission guarantee, has none, and
  is non-conforming on §11 today. audit-core's reading is upheld. The finding
  under it: §11 says "catalogued in §4 as a source of evidence" and §4
  catalogues no such thing, so flex-auth could not have answered from the text.
- **B4.** No standard version in a declaration. Every sidecar in the estate
  carries `standard_version: "0.7"` because ops-warden's reference form does —
  one change in one repository, not seven.
- **v0.8** stays held, with three stated conditions so the hold cannot drift.

Of the ten questions this record tracked, eight are ruled or answered.
Outstanding: `informed-decision`'s §4 membership (asked, not enrolled) and the
`role:` vocabulary, which needs A9 first.

### What the custodian got wrong, twice

Both errors were the same error. The sweep was run against flex-auth's
validator as a stand-in for §3, and published as an estate property without
stating the scope it ranged over. `Taxonomy` was in §3 all along, and the two
repositories named were never bound by §11. The reviewed repositories caught
both: `railiance-master` supplied the §3 citations, `informed-decision`
narrowed its own request rather than re-litigating, and gate-house's scope rule
names the defect generally. The custodian's contribution that survived is the
§3-`Engines`/§4-`Engine` disagreement, which became amendment A9.

## Application, 2026-09-21

- **ops-warden** applied GH-DEC-2026-017 to the reference form after verifying
  it at `gate-house@def0af2`. Its conformance checker listed `standard_version`
  as required, so any repository that copied the checker must drop the key from
  the checker's required list in the same commit, or a conforming declaration
  fails `MALFORMED`. Change set: `ops-warden/wiki/playbooks/netkingdom-layer-declaration.md`.
- **flex-auth** fixed its validator (four tokens, ASCII fold, §4 spelling, scope
  stated per run), published per-class emission guarantees in `cadence.yaml`,
  and holds G2 as a dated declared gap to 2026-10-19 under FLEX-WP-0031.
  FLEX-DEC-2026-015: `resource.system` follows the runtime, not the repository.
- **informed-decision** declares `Staff`/`pep-shaped` and asked for a §4 row with
  its guarantee reported as owed. The §3.4 fit — Staff is defined as
  non-deterministic; this repository is deterministic by test — stays open as
  INFD-IN-0007.
- **secrets-engine** established that its exec reads the ungoverned legacy path
  `secret/coulomb/whynot-design/npm/publish` (field `npm_token`), while ops-warden's
  runbook rotates the governed path (field `NPM_AUTH_TOKEN`). A rotation per the
  runbook would not reach the live publish path. Held by the founder.

Ten repositories still carry the pre-ruling sidecar form.

## Second round, 2026-09-21

GH-DEC-2026-017 is applied in thirteen repositories. No `standard_version` field
remains in any declaration, and no layer value was re-spelled. Six
repositories carried a copy of ops-warden's conformance checker, not five as
first counted; zone-engine's was under `tools/`. Each required
`standard_version`, and several compared layers with plain equality. Every one
changed in the same commit as its field.

Three questions about A12's reach went to gate-house with counts measured on
disk. The repositories' own reports had suggested a 3–3 split on the versioned
`standard:` path. On disk, only audit-core and user-engine still pin one.

- **flex-auth** closed FLEX-WP-0022. It enforces tenant-engine's invariant
  (`tenant` = `resource.id`) as a deny, and states and tests cross-tenant scope.
  One exception is named: user-engine's onboarding grant excludes
  `tenant:platform`. That was sent back to tenant-engine rather than decided.
  v3 is not rolled out.
- **tenant-engine** is admitted as an audit-core sender but cannot deliver:
  the egress NetworkPolicy, the URL, and the token projection are missing from
  its deploy manifests. TEN-IN-0005; this needs a credential path from custody (OpenBao, railiance-platform).
- **secrets-engine** surfaced a question: the service JWT design names
  `tenant:coulomb`, but the approval chain resolved to `tenant:platform`.

## Third round, 2026-09-21: GH-DEC-2026-020

gate-house ruled what A12 reaches (GH-DEC-2026-020, A12 r2):
- **Reached:** a version in the `standard:` path, and `companion_version`.
- **Not reached:** stance, claims and classification maps.
- **Checkers:** a re-runnable checker is sufficient if every run prints the version it checked against and its scope. kings-guard's `VALIDATED_AGAINST` pattern is the reference.

It is applied in eleven repositories. whitehat-security, which never received GH-DEC-2026-017 and which the custodian's rounds had also missed, applied both rulings.

The round produced the same failure a third time, now in the checkers: each wrote its own version detector, and they disagree. Measured:
- **Prose citations:** eight declarations carry a prose version citation, including gate-house's own. Seven carry the same inherited sentence, "Outside §5 by the v0.5 scope rule". The repositories split four ways on handling it while gate-house's ruling is pending.
- **`VALIDATED_AGAINST`:** six checkers name the v0.7 text in force; tenant-engine and flex-auth name the held v0.8.

ops-warden wrote one reference detector into its playbook (0f9ada0). All of this went to gate-house, with a proposed additional v0.8 flip condition.

## Fourth round, 2026-09-21: GH-DEC-2026-021 and B2 closed

gate-house ruled the third round's findings in GH-DEC-2026-021:
- **Prose citations:** the narrow reading. A12 reaches only a version carried as a pin, so no declaration changes. The ruling notes that this reading benefits gate-house. The wording is drafted as A12 r3 and sent for assent.
- **VALIDATED_AGAINST:** checkers name the accepted v0.7 plus the gate-house decisions they enforce. tenant-engine and flex-auth re-point now.
- **Detector:** ops-warden's playbook detector is the estate reference. Each copy converges on it when next edited, and no later than the post-flip commit.
- **Flip:** not added to GH-DEC-2026-019, because it would be circular as a precondition. Instead it is a post-flip task, GH-WP-0004-T11, and the flip notice must name all eight checkers.
- **A11 r2:** permits a single-repository conformance run.

B2 is closed. All four undeclared repositories declared their own layer:

| Repository | Layer |
|---|---|
| gate-house | Staff |
| key-cape | Tooling |
| ops-mason | Staff, pep-shaped |
| net-kingdom | Taxonomy |

Each reading agrees with §4, and GH-DEC-2026-019's third closing condition is met. Three things surfaced:
- **key-cape:** its token endpoint has the shape of a PIP, and its authentication enforcement sits where §3.3 places enforcement boundaries. It read both as Tooling behaviour.
- **ops-mason:** it writes OpenBao policies and auth roles, creates secret_ids and runs `kubectl apply`, gated by the founder approving the plan rather than by an access-engine decision. Its own earlier review note said otherwise. These are declared as dated gaps to 2026-12-21.
- **net-kingdom:** the canon repository carries runtime material, `identity-provisioner/` and `sso-mfa/k8s/`.

Still open: A11 r2 and A12 r3 assent, INFD-IN-0007 (the §3 cut, outside the §11 hold), and the role vocabulary after A9.

## Follow-ups, 2026-09-21

The founder approved A11 r2 and A12 r3, exercising `GOVERN`. The approval was relayed to gate-house under GH-WP-0004-T09 as the return for the four round members that deferred to the founder: audit-core, access-engine, ops-warden and net-kingdom. It does not stand in for approval-engine, kings-guard, informed-decision or railiance-master.

GH-DEC-2026-021's immediate changes are applied:

- **tenant-engine** (`ff0712b`) and **flex-auth** (`067d93a`) now name the accepted v0.7 in `VALIDATED_AGAINST`, and both converged on the reference detector. flex-auth kept one exemption: an empty version key is not flagged. It is justified by a Go struct field rather than by the ruling, and no declaration carries such a key. It is a candidate for removal at flex-auth's next edit of the detector.
- **ops-warden** (`3979152`): the playbook is now titled as the estate reference detector. Prose citations are recorded as not reached, with a note of what widens if A12 r3 is rejected. `intent_version` is named as a key that must not be flagged.

The reference detector flags a versioned path to any document, not only one naming the standard. GH-DEC-2026-021 §3 accepts that. No declaration carries such a path today.

## Terminology, 2026-09-21

This record and the custodian's messages today used bare "operator" for the founder's decisions. SecurityCanon's disambiguation rule forbids that: `Operator` is a CARING lifecycle role, and `OPERATE` is an Auth Mode. The founder's decisions today were authority over authority, which is `GOVERN`. The records are corrected. Messages already sent are not; later messages use the canon's terms.

The Kubernetes change gate is recorded in `docs/kubernetes-change-gate-decision.md` in Mode of Authority terms.
