Joseph Doherty 3dd7aa40ff docs: publish LocalDb 0.1.0 to the feed + reconcile component status against verified state
Publishes the three ZB.MOM.WW.LocalDb packages to the Gitea feed (restore-verified
from a scratch consumer) and adds the build/push.sh the other shared libs already have.

The status prose across CLAUDE.md, README.md and components/*/GAPS.md had drifted from
reality, so it was re-derived from the feed listing and the actual PackageReferences +
registration calls on each consumer's default branch rather than from prior claims.
Five claims were false: Health "not yet adopted" (all four apps wire MapZbHealth),
GalaxyRepository's mxaccessgw adoption "a follow-on" (its Server wires
AddZbGalaxyRepository), Configuration "not yet pushed", Secrets G-8 "not yet
committed", and Theme pinned at 0.2.0 (all four are on 0.3.1). Every doc also said
"three apps" while HistorianGateway is a fourth consumer of seven libs, and all
eight libraries' test counts were stale (re-ran each suite; all green).

Surfaces one previously unrecorded gap: Secrets source is at 0.1.3 with KEK rotation
committed, but the feed tops out at 0.1.2, so no app can consume rotation until it
is published.

Health and observability divergence tables are labelled historical, not re-verified —
the libraries are proven wired, but per-app probe coverage vs spec was not re-walked.

Raw Blame History

Auth — gaps & adoption backlog

Divergence of each project from spec/SPEC.md, and the ordered backlog to reach the shared ZB.MOM.WW.Auth library. Status legend: gap · 🟡 partial · matches.

Current state (verified 2026-07-18): feed carries 0.1.00.1.4; consumer pins are OtOpcUa 0.1.1, ScadaBridge 0.1.3, MxAccessGateway 0.1.4, HistorianGateway 0.1.4 (a fourth consumer this file predates, taking all four packages). OtOpcUa is three minors behind — it does not get the 0.1.4 API-key-expiry enforcement. Library suite: 215 passing, 1 skipped, green 2026-07-18.

ADOPTED 2026-06-02 (local-only). The full backlog (#1#8) was implemented across all three apps on each repo's feat/adopt-zb-auth branch — committed + spec/code-reviewed, then merged to each repo's local default (main/master) and PUSHED to origin (gitea) on 2026-06-03 (in sync; feat/* kept locally). Shared Auth.Ldap + Auth.ApiKeys (ScadaBridge inbound re-architected to keyId/Bearer), IGroupRoleMapper<TRole>, Transport-enum config, canonical ZbClaimTypes/ZbCookieDefaults, unified dev base DN dc=zb,dc=local, and the canonical-six roles (with ScadaBridge's accepted auditor/admin SoD collapse). Consumer pins: OtOpcUa 0.1.1, MxGateway 0.1.2, ScadaBridge 0.1.3. Detail: docs/plans/2026-06-02-auth-audit-normalization*.md. The /🟡 cells below describe the PRE-adoption divergence (kept for history).

Divergence vs spec

§1 LDAP config schema

Spec key OtOpcUa MxAccessGateway ScadaBridge
Section nesting 🟡 Authentication:Ldap (nested) MxGateway:Ldap (nested) flat ScadaBridge:Security:Ldap*
Transport enum UseTls bool UseTls bool LdapTransport enum
AllowInsecure 🟡 AllowInsecureLdap 🟡 AllowInsecureLdap 🟡 AllowInsecureLdap (rename)
UserNameAttribute UserNameAttribute UserNameAttribute LdapUserIdAttribute
GroupAttribute memberOf memberOf 🟡 LdapGroupAttribute (rename)
dev SearchBase dc=lmxopcua,dc=local dc=lmxopcua,dc=local dc=scadabridge,dc=local

Gap A1: adopt the Transport enum in OtOpcUa + gateway (replace UseTls). → Gap A2: ScadaBridge: nest keys + rename LdapUserIdAttributeUserNameAttribute, LdapGroupAttributeGroupAttribute. → Gap A3: unify the dev base DN (dc=lmxopcua vs dc=scadabridge) — pick one shared GLAuth base.

All three do bind-then-search; ScadaBridge has the most complete hygiene (RFC-4514 + filter escaping, per-op timeout, fail-closed on group lookup, username trim, service-account-bind distinction). 🟡 OtOpcUa/gateway: confirm each has filter escaping + fail-closed-on-group-lookup parity. → Gap B1: make ScadaBridge's hygiene the shared baseline; backfill any missing checks.

§3 group→role mapping

Mechanism split: OtOpcUa + gateway map in config (GroupToRole); ScadaBridge maps in the database (LdapGroupMapping). → Gap C1: IGroupRoleMapper<CanonicalRole> must support both backings; ship a config-backed and a DB/delegate-backed mapper.

Role vocabulary now standardized to the canonical six (spec/CANONICAL-ROLES.md); native enforcement stays per-project. → Gap C2: implement the canonical → native expansion in each project. ⚠ Removing Auditor collapses ScadaBridge AuditReadOnly→Viewer and Audit→Administrator, losing its auditor/admin separation-of-duties (accepted). OtOpcUa lacks a first-class Deployer (publish ⊂ FleetAdmin); ScadaBridge has no Operator/Engineer; mxaccessgw no Designer/Deployer — each project assigns only the applicable subset.

§4 API-key contract

OtOpcUa MxAccessGateway ScadaBridge
Has API keys n/a (OPC UA transport security) mxgw_…, SQLite, scopes + constraints 🟡 X-API-Key, per-method approval (Inbound API only)
Peppered HMAC-SHA256
Constant-time compare
Token format <prefix>_<id>_<secret> raw X-API-Key (no keyId/prefix structure)
Audit log append-only 🟡 (verify)

Gap D1: extract mxaccessgw's pipeline as ZB.MOM.WW.Auth.ApiKeys. → Gap D2: ScadaBridge Inbound API adopts it; reconcile token format and model "per-method approval" as the opaque constraint policy.

Cookie names differ (MxGatewayDashboard vs ZB.MOM.WW.ScadaBridge.Auth vs OtOpcUa control-plane cookie); claim-type conventions differ. → Gap E1: define canonical claim types + cookie defaults in ZB.MOM.WW.Auth.AspNetCore; each app keeps its own cookie name but shares attributes/claims.

§6 dev / secrets

All never-log-secrets and pepper-external. 🟡 escape-hatch flag names vary. Covered by A3 (base DN) + E.

Adoption backlog (ordered)

# Item Projects Priority Effort Risk Notes
1 Extract ZB.MOM.WW.Auth.Ldap from ScadaBridge's hardened impl all 3 High M Med security-sensitive; needs strong tests before cutover
2 Extract ZB.MOM.WW.Auth.ApiKeys from mxaccessgw Model A gw, SB High M Med gateway adopts first (it's the source), then SB
3 IGroupRoleMapper<TRole> seam + config & DB mappers (Gap C1) all 3 High S Low unblocks per-project role retention
4 Config migration to §1 schema (Gaps A1A2) all 3 Med S Low mechanical; do with #1
5 ZB.MOM.WW.Auth.AspNetCore claims/cookie conventions (Gap E1) all 3 (UIs) Med S Low incl. OtOpcUa Blazor Admin UI control-plane
6 Unify dev GLAuth base DN (Gap A3) all 3 Low S Low dev-only; touches fixtures/infra
7 Decide shared JWT/refresh helper vs per-project SB (+?) Low S Low only if a 2nd project wants the same
8 Adopt canonical roles: canonical → native mapping per project (Gap C2) all 3 Med M Med governance (assign canonical role per LDAP group org-wide) + each project's expansion; SB audit roles collapse

Sequencing: #3 first (cheap, unblocks), then #1 and #2 in parallel (independent libraries), then #4#5 alongside cutover, then #6#7 as cleanup. Each extraction lands behind tests in the source project before any consumer migrates. This stays consistent with the repos' loose coupling: adoption is opt-in per project, one consumer version-bump at a time.

Decisions still open

  • Shared dev base DN value (A3).
  • Whether constraints stay opaque object? or get a small IConstraintPolicy (shared-contract Q3).
  • Shared JWT/refresh helper or not (#7).
