+**Every feature-gated capability is now UI-gated, guardrailed by a flag registry and a declarative `requiresFeature` annotation (#2874, generalizing the create-user phone fix #2871).**
+
+`@objectstack/spec/kernel` gains `PUBLIC_AUTH_FEATURES` — a classification registry for all 13 boolean flags served at `/api/v1/auth/config`: consumption surface (crud/login/status), default semantics (opt-in `== true` vs default-on `!= false`), and the gated spec inputs or an exemption reason. A plugin-auth drift test pins the served key set to the registry, and a platform-objects completeness guard pins the registry to the actual gates in both directions.
+
+`ActionSchema`/`ActionParamSchema` gain `requiresFeature: '<flag>'` (enum-checked), lowered at parse time into the canonical `visible` CEL predicate per the flag's registered semantics, AND-composed with any explicit `visible`, and stripped from the output — renderers and lint see only `visible`, so objectui needs no changes. All 22 hand-written `features.*` gates migrated (behavior-locked by an exact-string matrix test), and the audit gated 17 previously naked capability-dependent actions: the six `sys_user` platform-admin actions, six 2FA actions, and five `sys_oauth_application` actions now hide when their plugin is off instead of rendering buttons that 404.

 This is a narrower scope than [record-alert](/docs/protocol/objectui/record-alert) conditions (which also expose `os.user` / `os.org` / `os.env`) — action predicates see the record only.
 
+#### Capability gates: `requiresFeature`
+
+When an action (or param) only works with an opt-in auth capability behind it — the better-auth `admin` plugin, `phoneNumber`, `twoFactor`, … — gate it with **`requiresFeature: '<flag>'`** instead of a hand-written `features.*` predicate. The flag names the public feature flag served at `/api/v1/auth/config` (see `PUBLIC_AUTH_FEATURES` in `@objectstack/spec/kernel`); at parse time the schema lowers it into the canonical `visible` predicate — `features.X == true` for opt-in flags, `features.X != false` for default-on flags — AND-composing with any explicit `visible` you also declare, then strips itself from the output. An unknown flag name fails the parse.
+
+```yaml
+# Hidden entirely when the admin plugin is off (instead of a button that 404s)
+name: ban_user
+label: Ban User
+type: api
+target: /api/v1/auth/admin/ban-user

+
+# Composes with a residual row predicate:
+# (!record.disabled) && features.oidcProvider != false
+name: disable_oauth_application
+visible: "!record.disabled"
+requiresFeature: oidcProvider
+```
+
+This is how the platform keeps "form follows plugin" (#2874): the UI never advertises an input the default backend would reject.

+/**
+ * Completeness guard (#2874 P2): the PUBLIC_AUTH_FEATURES registry
+ * (`@objectstack/spec/kernel`) and the feature gates actually carried by the
+ * platform objects must stay in lockstep, in BOTH directions:
+ *
+ * 1. Forward (registry → objects): every `gatedInputs` path must resolve to a
+ *    real action/param whose lowered `visible` predicate carries the flag's
+ *    gate. Removing a `requiresFeature` annotation (or the whole input)
+ *    without updating the registry turns this red.
+ * 2. Reverse (objects → registry): every `features.<name>` reference inside
+ *    any action/param `visible` predicate must name a registry flag AND be
+ *    booked in that flag's `gatedInputs`. Adding a gate without registry
+ *    bookkeeping turns this red.
+ *
+ * Scope notes: objects that moved to capability plugins per ADR-0029 K2
+ * (plugin-security / plugin-sharing / plugin-audit / service-realtime /
+ * plugin-webhooks) are outside this package and this guard; none of them
+ * reference `features.*` today. Object FIELDS (`visibleWhen`) carry no
+ * feature gates today and are not walked. Per the issue's explicit non-goal,
+ * this guard cannot catch a brand-new capability-dependent input that was
+ * never annotated at all — that ground truth lives in plugin runtime
+ * behavior.
