NK-WP-0048 - Establish SecurityCaseTypes so that known security cases are light

Why

The founder's direction (2026-10-08): setting up a security integration of a kind that has been done before should be easy, meaning accept the case, then ops-mason arranges it and ops-warden follows through. Setting up a new kind needs ample documentation and tests and an informed-decision, because its shape is part of the security architecture.

Today every integration is hand-built: per-client helper scripts, per-lane custody, founder checklists. The trigger was KEY-WP-0038 (Forgejo as an OIDC client), whose next step was going to be yet another hand-written rollout script.

This plan continues the pattern work of NK-WP-0008 (pattern infospace), NK-WP-0009 (tutorials) and NK-WP-0030 (scenario composition). It turns patterns into SecurityCaseTypes that ops-mason and ops-warden can execute. Canon: canon/standards/security-case-types_v0.1.md (proposed).

Companion plans: ops-mason MASON-WP-0010 (materialization) and ops-warden WARDEN-WP-0044 (follow-through).

T01 — Accept the terminology and the canon

Founder review of canon/standards/security-case-types_v0.1.md, including its section 10 open questions. On acceptance the canon status goes from proposed to accepted.

2026-10-08: accepted by the founder (in session). Canon status accepted; section 10's open questions are carried forward to the first type (T04, T05).

T02 — Inventory the de-facto types already built by hand

Read-only. List every security integration built so far and group them by shape. Known starting points:

• browser OIDC relying parties on key-cape: informed-decision-approver, coulomb-social, user-engine portal, openbao-admin, and Forgejo (pending)
• confidential service clients with client_credentials: secrets-engine approval, requester and openbao clients, approval-engine operator
• workload KV read lanes on OpenBao: the railiance-platform credential lane designs and CCRs, for example railiance-backup-offsite-lane
• short-lived SSH certificates through ops-warden (warden sign)
• tunnelled operator access (ops-bridge)

For each: the repositories involved, the hand-built steps, attended human steps, custody paths, verification evidence, and rollback (if any). Output docs/security-case-type-inventory.md, ranking candidate types by how often the shape recurs and how much manual work each instance costs today.

2026-10-08: done, docs/security-case-type-inventory.md. 36 of 37 CCRs are already request_type: workload-kv-read, a de-facto type reviewed each time as if it were new. Browser clients: 5 hand-built plus Forgejo, each with its own rollout script. Confidential service clients need a registration plus two or three KV-read CCRs each. A forge read identity is needed in bulk by ORGREF-WP-0002-T06. Recommendation: oidc-browser-relying-party first (unblocks the forge), workload-kv-read second (largest payoff), then forge-read-identity.

T03 — Schema, template and validator

• canon/schemas/security-case-type_v0.1.schema.json and security-case_v0.1.schema.json
• security-case-types/_template/ with type.yaml, README.md and tests to copy
• a validator, extending tools/security-scenario-composer/, that checks a type, checks a case against its type, and renders the case into the composer's deterministic plan (still execution.permitted: false)

Acceptance: the validator rejects missing sections, secret-shaped parameter values, unpinned providers and cases against non-implemented types, with tests for each.

2026-10-08: done. canon/schemas/security-case-type_v0.1.schema.json and security-case_v0.1.schema.json; tools/security-case-types/security_case_validator.py (validate-type, validate-case, render, reusing the scenario composer); security-case-types/_template/ (a valid, runnable example type over net-kingdom.local-identity, with README sections, an example case and tests that travel with every copy). 31 tests pass, including the composer's existing suite.

T04 — Define the first type: browser OIDC relying party

security-case-types/oidc-browser-relying-party/, version 1.0:

• parameters: client id, display name, exact redirect URIs, scopes, client type (confidential or public), MFA pin, the groups the consuming service maps, custody path for the secret (confidential only), consuming service and its owner
• composition: key-cape client registration (key-cape declares it as a playbook capability), secret minting into custody (railiance-platform), LLDAP group existence and membership (net-kingdom identity-provisioner), handover to the consuming service
• materialization (ops-mason) and follow-through (ops-warden) sections
• verification: discovery lists the redirect URI; a test sign-in returns the expected claims for one human; anonymous access to the custody path is denied
• rollback: remove exactly this client and its custody path
• README: threat model, MFA rationale, why redirect URIs are exact, which steps still need an attended login and how that is minimised
• reference instances: informed-decision-approver, coulomb-social, user-engine portal, openbao-admin

Acceptance: complete per canon section 3, tests green, status proposed.

2026-10-08: done. security-case-types/oidc-browser-relying-party/ 1.0 (proposed): type.yaml with 12 parameters (the custody reference is required only for confidential clients), composition over key-cape's new key-cape.oidc-client-registration declaration (contract PASS, maturity: planned), materialization and follow-through, verification and rollback, all conditional on client type where it matters. One attended step, register-client, justified by the live registry being a Kubernetes Secret. README with threat model, alternatives, an honest fit table (portal and vergabe fit; Forgejo is the first confidential case; openbao-admin, coulomb.social and informed-decision-approver do not fit 1.0), and known limits. Examples: Forgejo (checked against the accepted request) and a public portal. The validator gained when / required_when conditions and provider discovery. 43 tests pass. ops-mason's and ops-warden's sections are drafted in the type. Their owners review them in MASON-WP-0010-T01 and WARDEN-WP-0044-T01 before acknowledgment (T05).

T05 — Acknowledge the type through informed-decision

Prepare the Decision Memo from the type's README and type.yaml and submit it through informed-decision's production intake. On acknowledgment the type moves to acknowledged.

2026-10-08: Decision Memo prepared. Hub decision e418263e-a71f-4f01-a970-c87c9e187c09. security-case-types/oidc-browser-relying-party/decision/: packet.md (question, one act, what acknowledging does not do, the shape, alternatives, attended steps, limits, evidence), build_intake.py and the built intake.json (memo class decision-record, review group net-kingdom-admins, resolves the hub decision on answer). The envelope passes informed-decision's own validate_submission. Queuing it is an attended operator step, a write inside the production dispatcher pod:

kubectl -n state-hub exec -i deploy/state-hub-memo-dispatch -- \
  python -m api.services.memo_dispatch --queue /data/private enqueue --envelope /dev/stdin \
  < security-case-types/oidc-browser-relying-party/decision/intake.json

The answer then appears for review in informed-decision.

2026-10-08: queued by the founder (pending, queued) after one refusal: the first envelope's idempotency key was not State Hub's stable state-hub.<decision>.<memo> form, and the builder now validates against both sides. The dispatcher delivered it to informed-decision (ledger 7 → 8 delivered). T05 waits for the founder's answer in informed-decision, which resolves hub decision e418263e.

2026-10-08: ops-mason's review (MASON-WP-0010-T01) folded into the type, still 1.0 proposed: secret_ref is no longer a parameter, the type derives platform/workloads/keycape/{client_id}; policies are workload-kv-read-keycape-{client_id}-eso and workload-kv-read-keycape-{client_id}-{consuming_service}, each with a templated body (read on that one data path); new openbao_role external-secrets-keycape-{client_id} (Kubernetes auth, ESO service account, 15m, no default policy); catalog entry {consuming_service}-keycape-client; the two rollback steps on the KV path collapse into one metadata delete. The schema and validator now require a body on policy and role items. 105 tests pass. Two consequences: the delivered memo describes the type before these changes (a case-set custody reference, two differently named policies, no ESO role), so the founder answers on a superseded shape unless the memo is re-sent; and Forgejo's custody path moves from the accepted request's proposed platform/workloads/forgejo/netkingdom-oidc-client to platform/workloads/keycape/forgejo, which key-cape (KEY-WP-0038) and railiance-apps (RAPPS-WP-0016-T02) need to adopt in T06. ops-warden's review (WARDEN-WP-0044-T01) is still in progress.

2026-10-08: revised memo nk-wp-0048-t05-oidc-browser-relying-party-r2 built (packet.md, intake.json, packet sha256:af6435e2…); it states that it supersedes the first memo and passes informed-decision's and the dispatcher's validation. It needs a new memo id because the dispatcher refuses new content under a delivered idempotency key (idempotency_conflict). Queuing it is the same attended step as above. Both memos serve hub decision e418263e; the first answer resolves it, so the founder answers r2 and leaves the first memo unanswered. key-cape and railiance-apps were told about Forgejo's new custody path.

T06 — First KnownSecurityCase: Forgejo

Write security-cases/forgejo-netkingdom-oidc.yaml from the parameters the founder accepted in KEY-WP-0038-T01 (key-cape/docs/forgejo-oidc-client-request.yaml), so that acceptance carries over as the case acceptance. ops-mason materializes it; ops-warden follows through and verifies it. The type becomes implemented once this reference case is live.

This replaces the hand-built path proposed for KEY-WP-0038-T02.

T07 — Queue the next types

From the T02 ranking, open the next type drafts (likely the confidential service client and the workload KV read lane), each to be acknowledged on its own. Record which existing hand-built instances get adopted as cases, without rewriting them in place.

T08 — identity-provisioner: ensure service-access groups

The type's ensure-groups step calls identity-provisioner groups ensure --groups <list> --members <group=user+user;...>. The provisioner already has idempotent _ensure_group and _add_group, but exposes only tenant-scoped operations. Add the general operation (create if absent, add the listed memberships, never remove others), its rollback (remove only this case's memberships), tests, and the ops-warden route for its service identity.

2026-10-08: done. identity-provisioner/provisioner.py gained ensure_service_groups (POST /v1/groups/ensure) and revoke_service_groups (POST /v1/groups/revoke), behind the existing service-token check. Names matching tenant*, netkingdom-* and lldap_* are reserved; members must already exist; everything is validated before any change; memberships are read back before success; nothing else is ever removed; groups are deleted only when asked and empty. 7 new tests (39 in the provisioner suite). The type's ensure-groups step and its rollback now name these endpoints. The ops-warden route for the provisioner's service token belongs to WARDEN-WP-0044-T01.

T09 — The keycape-client entry point and its declaration

Planned first as key-cape KEY-WP-0038-T04. Moved here because the machinery a live registration needs already lives in net-kingdom, where KeyCape is deployed (sso-mfa/k8s/keycape/): the contained kubectl, the cluster-identity pin and the issuer pin. A copy in key-cape would drift.

2026-10-08: done. sso-mfa/k8s/keycape/keycape-client.py derives the KeyCape client record from a case (client-from-case). It adds or removes exactly one client with the existing safeguards (byte-preserving merge, exact match or refuse, shared-reference refusal, compare-and-swap, read-back, contained errors), requires the Deployment env binding first for confidential clients, and requires the case acceptance record for apply instead of a per-client founder decision id. 15 tests, including a regression showing that the vergabe case reproduces its hand-built registration exactly; all 71 helper tests pass. Declaration capabilities/playbooks/net-kingdom.keycape-client-registration.yaml (contract PASS, maturity: implemented) replaces key-cape's draft. The type now pins it, and for confidential clients adds deliver-secret (delivery from custody into the sso namespace) and bind-env (Deployment env), attended in the same session as register-client. The per-client helpers stay until their clients are adopted as cases.
