feat(WP-0009): IHF GAAF Compliance Foundation — type registries, extension manifests, architectural contracts

Implements IHUB-WP-0009: closes four GAAF-2026 gaps before domain hub work begins.
- TypeRegistry helper + controllers/views (hub_kind, hub_capability_manifest)
- HubCapabilityManifest entity with validation and registry linkage
- ARCHITECTURE-LAYERS.md + CI-enforced boundary contracts
- Alembic migration 1743724800, fitness tests (Test/Architecture/)
- GAAF spec, Operational Architecture spec, domain hub extension guide
- Updates to CLAUDE.md, SCOPE.md, Schema.sql, Routes, FrontController, Types

state_hub_sync: pending (tunnel was STALE at completion time; run fix-consistency)

+
+**Framework:** GAAF-2026 v1.0
+**Last reviewed:** 2026-03-31
+**Next review:** 2026-09-30
+**Repository:** inter-hub
+**Purpose:** Reference implementation of the Interaction Hub Framework (IHF) —
+a governed, observable interaction substrate for hub-based AI-enabled software
+systems.
+
+---
+
+## Layer Map
+
+### Core — High rigidity, frozen after v1
+
+Domain-agnostic primitives and invariants. The substrate that all functional
+modules depend on.
+
+**Entities:** `Hub`, `Widget`, `WidgetVersion`, `InteractionEvent`, `Annotation`,
+`AnnotationThread`
+
+**Traceability chain:** `Widget → InteractionEvent / Annotation →
+RequirementCandidate → Requirement → DecisionRecord → ImplementationChangeReference
+→ DeploymentRecord → OutcomeSignal`
+
+**Contracts:**
+- [widget-envelope-v1](contracts/core/widget-envelope-v1.md) — widget DOM
+  protocol, required `data-*` attributes
+- [append-only-events-v1](contracts/core/append-only-events-v1.md) — immutability
+  invariant on `interaction_events` and `outcome_signals`
+
+**Key invariants:**
+- `interaction_events` and `outcome_signals` are append-only (DB-trigger enforced)
+- Widget identity (UUID) is stable across implementation changes
+- Actor attribution is explicit on all interaction and decision artifacts
+
+### Functional — Medium rigidity, evolvable
+
+Value-realisation modules. Each module has a declared maturity. See
+`docs/functional-modules.md` for the full maturity register.
+
+**Modules:**
+- RequirementCandidate lifecycle (triage, reviewer assignment) — **Stable**
+- DecisionRecord + governance ledger — **Stable**
+- Requirements (promoted from candidates) — **Stable**
+- DeploymentRecord + OutcomeSignal — **Stable**
+- AgentProposal + AgentReviewRecord + ConfidenceAnnotation — **Beta**
+- Cross-framework adapter contracts (EnvelopeEmissionContract,
+  InteractionReportingContract, WidgetAdapterSpec) — **Stable**
+- FrictionScore + BottleneckRecord — **Beta**
+- HubHealthSnapshot — **Beta**
+- CrossHubPropagation — **Experimental**
+- WidgetOwnership — **Stable**
+- HubRoutingRule — **Stable**
+- FederatedPolicyOverlay — **Beta**
+- StewardshipRole — **Stable**
+- ArchiveRecord + lineage inspector — **Beta**
+- Type registries (WidgetTypeRegistry, EventTypeRegistry,
+  AnnotationCategoryRegistry, PolicyScopeRegistry) — **Beta**
+- HubCapabilityManifest — **Beta**
+
+**Contract:** [interaction-reporting-v1](contracts/functional/interaction-reporting-v1.md)
+
+### Customization — Low rigidity, hub-specific adaptation
+
+Hub-specific routing behaviour and policy configuration. These are Functional
+modules in implementation but serve the Customization purpose of adapting
+framework behaviour per-hub without forking code.
+
+**Entities:** `HubRoutingRule`, `FederatedPolicyOverlay`
+
+**Note:** A formal Customization layer manifest (per-hub configuration contract
+with migration support) is planned for IHF v1.0. Currently these are Functional
+modules with hub-scoped parameters.
+
+### Configuration — Very low rigidity, declarative state
+
+User-controlled settings validated against known schemas.
+
+**Fields:** `hubs.hub_kind`, `hubs.domain`, `hubs.api_key`,
+`widgets.policy_scope` (validated against `policy_scope_registry`)
+
+**Env vars:** `IHP_SESSION_SECRET`, `DATABASE_URL`, `IHP_BASEURL`,
+`IHP_ANTHROPIC_API_KEY`
+
+**Note:** Runtime-validated configuration schemas per hub are planned.
+Currently hub configuration fields are validated at the controller layer.
+
+### Extensions — Cross-cutting, externally supplied
+
+Domain hub vocabulary registration. The mechanism by which dev-hub, ops-hub,
+fin-hub, sec-hub, and other consumers extend the framework with their
+domain-specific types.
+
+**Entities:** `HubCapabilityManifest`, `WidgetTypeRegistry`, `EventTypeRegistry`,
+`AnnotationCategoryRegistry`, `PolicyScopeRegistry`
+
+**Contract:** [hub-capability-manifest-v1](contracts/extensions/hub-capability-manifest-v1.md)
+
+---
+
+## Dependency Rule
+
+```
+Core ← Functional ← Customization ← Configuration
+Extensions plug into Core or Functional only via manifests and type registries.
+
+Domain hubs (consumers) depend on Core and Functional.
+They extend via Extensions (manifest registration).
+They configure via Configuration (hub_kind, policy_scope, api_key).
+```
+
+Upward dependencies (Functional → Core) are permitted.
+Downward dependencies (Core → Functional) are **forbidden**.

+
+## GAAF-2026 Scorecard
+
+*Initial assessment: 2026-03-31 (post IHUB-WP-0009)*
+
+| Layer | Score (0–5) | Weight | Weighted | Notes |
+|---|---|---|---|---|
+| Core | 3.8 | 30% | 1.14 | Contracts formalised; type registries anchor discriminators |
+| Functional | 3.2 | 20% | 0.64 | Maturity labels added; demand signals still informal |
+| Customization | 2.5 | 15% | 0.38 | HubRoutingRule/Overlay present; no formal manifest yet |
+| Configuration | 3.0 | 10% | 0.30 | Registry-backed validation added; hub config schema planned |
+| Extensions | 3.5 | 10% | 0.35 | HubCapabilityManifest operational; manifest protocol Beta |
+| Cross-layer | 3.5 | 15% | 0.53 | Fitness functions in CI; contracts documented; layer map current |
+| **Total** | | | **3.34** | Usable but vulnerable — Phase 9 ready |
+
+**Interpretation:** 3.34 = Usable but vulnerable (2.5–3.4). Phase 9 may begin.
+Target for Phase 10 exit: ≥3.5 (Strong).
+
+*Score ≥3.5 target criteria for Phase 10:*
+- Customization layer manifest implemented (per-hub configuration contract)
+- Functional module demand signals formalised
+- Hub config schema runtime-validated
+
+---
+
+## Architectural Fitness Functions
+
+Implemented in `Test/Architecture/LayerBoundarySpec.hs`.
+Run as part of the standard `test` command.
+
+| Test | What it checks | On failure |
+|---|---|---|
+| Test 1 — Core immutability | Schema contains all 4 append-only triggers | Hard failure |
+| Test 2 — Contract artifacts | `/contracts/` key files exist | Hard failure |
+| Test 3 — Registry non-empty | All 4 type registries have ≥1 active entry | Hard failure |
+| Test 4 — No bare TEXT discriminators | New columns after GAAF marker use registry refs | Hard failure |
+| Test 5 — Domain hub manifest | Domain hubs have active manifests | Warning only |
+
+---
+
+## GAAF Architectural Laws (Applied to inter-hub)
+
+1. **Type discriminator columns** (`widget_type`, `event_type`, `category`,
+   `policy_scope`) must reference a registry or carry a CHECK constraint.
+   No new bare TEXT type discriminators after IHUB-WP-0009.
+
+2. **Core tables** (`widgets`, `interaction_events`, `annotations`, `hubs`,
+   `requirement_candidates`, `requirements`, `decision_records`,
+   `deployment_records`, `outcome_signals`) must not have columns added without
+   a corresponding review of `/contracts/core/`.
+
+3. **Append-only invariant** on `interaction_events` and `outcome_signals` is
+   permanent. No migration may remove or bypass the enforcement triggers.
+
+4. **Domain hub types** must be declared in a `HubCapabilityManifest` before
+   use. Unmanifested hub-owned types are flagged by fitness function Test 5.
+
+5. **Extensions plug into Core/Functional via contracts**, not via direct schema
+   mutations. A domain hub that needs a new entity adds it to its own schema
+   and links to IHF core entities via FK; it does not modify IHF core tables.
+
+---
+
+## Decisions Log
+
+| Date | Decision | Rationale |
+|---|---|---|
+| 2026-03-31 | Adopted GAAF-2026 as architectural compliance framework | Post-Phase 8 review identified gaps in extension layer, type safety, and contract formalisation |
+| 2026-03-31 | Type registries over CHECK constraints | Registries enable Phase 10 marketplace discovery; CHECK constraints are inflexible for domain extension |
+| 2026-03-31 | HubCapabilityManifest in inter-hub (not hub-core) | hub-core not yet implemented; manifest provides DB-side registration contract immediately |
+| 2026-03-31 | hub_kind 'framework' has unique index constraint | Prevents accidental creation of a second framework hub row |

+## GAAF Architecture Rules (enforced from IHUB-WP-0009)
+
+These rules apply to all code written after Phase 8 completion:
+
+1. **Type discriminator columns** (`widget_type`, `event_type`, `category`, `policy_scope`) must reference a registry table or carry a CHECK constraint. No bare TEXT for new type discriminators.
+2. **New hub-owned types** must be declared in the hub's `HubCapabilityManifest` before use. Register via the Extensions admin UI.
+3. **Core tables** (`widgets`, `interaction_events`, `annotations`, `hubs`, and their Phase 1–4 dependents) must not have new columns added without a corresponding update to `/contracts/core/`.
+4. **Append-only invariant** on `interaction_events` and `outcome_signals` is permanent. Never propose a migration that removes or bypasses those triggers.

 - Stability: core artifact model and schema are stable; Phase 6 contracts and Phase 8 activated policy overlays are immutable once active; native IHP widgets unaffected; Phase 7 observability scores are recomputed (not append-only), health snapshots are append-only; Phase 8 ownership records are soft-audit (no delete), archival is soft-delete (is_archived flag)

+# IHF Contract Catalog
+
+**Framework:** GAAF-2026
+**Last reviewed:** 2026-03-31
+**Repository:** inter-hub
+
+This directory contains the versioned, machine-readable contracts for each
+GAAF-2026 layer. Contract files are the authoritative declaration of
+interface, invariants, compatibility rules, and validation requirements for
+every public surface in the framework.
+
+The canonical implementation of each contract is the PostgreSQL schema and
+Haskell controllers. These files are the *discoverable declaration* — the
+human and agent-readable companion that makes intent explicit without
+requiring the source code to be read.
+
+---
+
+## Core Contracts
+
+| Contract | File | Version | Status |
+|---|---|---|---|
+| Widget Envelope | [core/widget-envelope-v1.md](core/widget-envelope-v1.md) | 1.0 | Active |
+| Append-Only Events | [core/append-only-events-v1.md](core/append-only-events-v1.md) | 1.0 | Active |
+
+Core contracts are **immutable after activation**. New requirements produce a
+new version (v1.1, v2.0); the old version remains readable for audit.
+
+---
+
+## Functional Contracts
+
+| Contract | File | Version | Status |
+|---|---|---|---|
+| Interaction Reporting API | [functional/interaction-reporting-v1.md](functional/interaction-reporting-v1.md) | 1.0 | Active |
+| Module Maturity Labels | [functional/module-maturity-labels.md](functional/module-maturity-labels.md) | 1.0 | Active |
+
+Functional contracts are **evolvable with minor-version notice**. Breaking
+changes require a major version bump and a deprecation window.
+
+---
+
+## Extensions Contracts
+
+| Contract | File | Version | Status |
+|---|---|---|---|
+| Hub Capability Manifest | [extensions/hub-capability-manifest-v1.md](extensions/hub-capability-manifest-v1.md) | 1.0 | Active |
+
+Extensions contracts govern how domain hubs register their vocabulary and
+capabilities with the framework.
+
+---
+
+## Contract Lifecycle
+
+```
+Draft → Active → Superseded
+              ↓
+           (never deleted — old versions remain for audit)
+```
+
+A contract becomes Active when:
+- Its corresponding schema and code are deployed
+- It is referenced in `ARCHITECTURE-LAYERS.md`
+
+A contract is Superseded when a new version replaces it. The old file
+remains with a `superseded_by` note at the top.
+
+---
+
+## Adding a New Contract
+
+1. Create the file in the appropriate layer directory
+2. Follow the header format: name, version, date, status, layer
+3. Document: interface, invariants, compatibility rules, validation rules,
+   failure mode
+4. Add an entry to this README table
+5. Reference it in `ARCHITECTURE-LAYERS.md`

+# Append-Only Events Contract
+
+**Name:** append-only-events
+**Version:** 1.0
+**Date:** 2026-03-31
+**Status:** Active
+**Layer:** Core
+**Immutable:** Yes — this invariant is permanent and cannot be relaxed
+
+---
+
+## Purpose
+
+Interaction events and outcome signals are the primary observational record of
+the IHF. Their integrity as an append-only log is a foundational invariant:
+governance, traceability, and antifragility all depend on the fact that the
+historical record cannot be silently rewritten.
+
+---
+
+## Invariant
+
+The following tables are **append-only**:
+
+| Table | Trigger (no update) | Trigger (no delete) |
+|---|---|---|
+| `interaction_events` | `interaction_events_no_update` | `interaction_events_no_delete` |
+| `outcome_signals` | `outcome_signals_no_update` | `outcome_signals_no_delete` |
+
+No row in either table may be modified or deleted after insertion. This
+invariant is enforced at the PostgreSQL level by `BEFORE UPDATE` and
+`BEFORE DELETE` triggers that raise exceptions. It cannot be bypassed by
+application code.
+
+---
+
+## Enforcement
+
+```sql
+-- Implemented in Application/Schema.sql
+CREATE TRIGGER interaction_events_no_update
+    BEFORE UPDATE ON interaction_events
+    FOR EACH ROW EXECUTE FUNCTION prevent_interaction_event_mutation();
+
+CREATE TRIGGER interaction_events_no_delete
+    BEFORE DELETE ON interaction_events
+    FOR EACH ROW EXECUTE FUNCTION prevent_interaction_event_mutation();
+
+-- Same pattern for outcome_signals
+```
+
+The trigger function raises:
+```
+"interaction_events is append-only: UPDATE and DELETE are not permitted"
+```
+
+---
+
+## Correction Policy
+
+Erroneous events **must not** be corrected by modifying the original row.
+The correct approach is to insert a new event:
+
+```json
+{
+  "event_type": "retracted",
+  "metadata": {
+    "retracted_event_id": "<uuid of original event>",
+    "reason": "incorrect actor attribution"
+  }
+}
+```
+
+The original event remains in the table. Downstream analysis should treat
+`retracted` events as markers that exclude the referenced event from
+calculations.
+
+---
+
+## Failure Mode
+
+Any attempt to UPDATE or DELETE a row in `interaction_events` or
+`outcome_signals` raises a PostgreSQL exception with SQLSTATE `P0001`.
+The calling transaction is aborted. No partial mutation is possible.
+
+---
+
+## Scope
+
+This contract applies **only** to `interaction_events` and `outcome_signals`.
+
+Other append-oriented tables (`triage_states`, `widget_ownerships`,
+`stewardship_roles`) use the same conceptual pattern (soft expiry instead of
+update, no hard delete) but are not covered by DB-trigger enforcement. Their
+append semantics are enforced by application-layer controller conventions.
+
+---
+
+## Implementation Reference
+
+- Functions: `prevent_interaction_event_mutation()`,
+  `prevent_outcome_signal_mutation()` in `Application/Schema.sql`
+- The architectural fitness function `Test/Architecture/LayerBoundarySpec.hs`
+  (Test 1) verifies these trigger names are present in the schema

+# Widget Envelope Contract
+
+**Name:** widget-envelope
+**Version:** 1.0
+**Date:** 2026-03-31
+**Status:** Active
+**Layer:** Core
+**Immutable:** Yes — changes require v1.1 with backwards-compatible additions only
+
+---
+
+## Purpose
+
+The Widget Envelope is the metadata boundary attached to every rendered widget.
+It enables the IHF capture pipeline to attribute any DOM event to a governed
+widget without coupling to the widget's implementation.
+
+Any UI technology that emits the required `data-*` attributes on a DOM element
+is a first-class IHF participant.
+
+---
+
+## Required Attributes
+
+Every widget root element **MUST** carry all of the following:
+
+| Attribute | Format | Example |
+|---|---|---|
+| `data-widget-id` | UUID (RFC 4122) | `data-widget-id="550e8400-e29b-41d4-a716-446655440000"` |
+| `data-hub-id` | Registered hub slug (TEXT) | `data-hub-id="ops-hub"` |
+| `data-view-context` | Dot-separated path (TEXT) | `data-view-context="ops.incidents.list"` |
+| `data-widget-type` | Registered name from `widget_type_registry` | `data-widget-type="chart"` |
+
+---
+
+## Optional Attributes
+
+| Attribute | Format | Notes |
+|---|---|---|
+| `data-capability-ref` | TEXT | Links widget to a hub capability |
+| `data-policy-scope` | Registered name from `policy_scope_registry` | Defaults to `internal` if absent |
+| `data-widget-version` | Integer as string | Current widget version number |
+| `data-experiment-variant` | TEXT | A/B experiment identifier |
+| `data-requirements-thread-ref` | UUID | Links to an open AnnotationThread |
+
+---
+
+## Validation Rules
+
+1. `data-widget-id` must be a valid UUID. Non-UUID values cause the envelope to
+   be treated as malformed.
+2. `data-hub-id` must match the `slug` of a registered hub in the `hubs` table.
+   Unknown hub slugs are logged but do not block event capture.
+3. `data-widget-type` must exist in `widget_type_registry` with `status = 'active'`
+   at the time of capture. Events from deprecated types are accepted but flagged.
+4. `data-view-context` has no format enforcement in v1.0 beyond non-empty.
+
+---
+
+## Failure Mode
+
+- **Missing required attribute**: the capture pipeline logs a
+  `malformed_envelope` event with the missing attribute names in `metadata`.
+  The original interaction event is **not** stored. This is fail-safe, not
+  fail-loud — the UI does not crash.
+- **Unknown hub slug**: event is stored with `metadata.hub_warning = "unknown_hub_slug"`.
+- **Unregistered widget_type**: event is stored with
+  `metadata.type_warning = "unregistered_widget_type"`. No 422 is returned to
+  the frontend (retroactive registration is possible).
+
+---
+
+## Backwards Compatibility Rule
+
+v1.0 is frozen. New optional attributes may be added in v1.1 without breaking
+existing implementations. Removing any attribute, or making an optional
+attribute required, requires a new major version (v2.0) with a migration window.
+
+---
+
+## Implementation Reference
+
+- Schema enforcement: `widgets.widget_type` validated against `widget_type_registry`
+  on create/update in `WidgetsController`
+- Client-side: `static/ihf-annotation-launcher.js` reads `data-widget-id` and
+  `data-hub-id` from the nearest ancestor with these attributes
+- Server-side envelope rendering: `widgetEnvelope` HSX helper in
+  `Application/Helper/View.hs`

+# Hub Capability Manifest Contract
+
+**Name:** hub-capability-manifest
+**Version:** 1.0
+**Date:** 2026-03-31
+**Status:** Active
+**Layer:** Extensions
+**Maturity:** Beta
+
+---
+
+## Purpose
+
+The Hub Capability Manifest is the formal extension registration mechanism of
+the IHF. It is the contract by which a domain hub (dev-hub, ops-hub, fin-hub,
+sec-hub) declares the vocabulary it introduces to the framework: widget types,
+event types, annotation categories, and policy scopes.
+
+Without an active manifest, a domain hub is an unregistered participant. Its
+widgets and events are accepted by the framework, but its type vocabulary is
+not namespaced, not validated, and not discoverable in Phase 10's marketplace.
+
+---
+
+## Schema
+
+```sql
+CREATE TABLE hub_capability_manifests (
+    id UUID DEFAULT uuid_generate_v4() PRIMARY KEY NOT NULL,
+    hub_id UUID NOT NULL UNIQUE REFERENCES hubs(id),
+    manifest_version TEXT NOT NULL DEFAULT '1.0',
+    declared_widget_types JSONB NOT NULL DEFAULT '[]',
+    declared_event_types JSONB NOT NULL DEFAULT '[]',
+    declared_annotation_categories JSONB NOT NULL DEFAULT '[]',
+    declared_policy_scopes JSONB NOT NULL DEFAULT '[]',
+    capability_description TEXT,
+    contact TEXT,
+    status TEXT NOT NULL DEFAULT 'draft',
+    activated_at TIMESTAMP WITH TIME ZONE,
+    created_at TIMESTAMP WITH TIME ZONE DEFAULT now() NOT NULL,
+    updated_at TIMESTAMP WITH TIME ZONE DEFAULT now() NOT NULL
+);
+```
+
+---
+
+## Registration Workflow
+
+```
+1. Create manifest in draft
+      ↓
+2. Declare types (edit declared_* arrays)
+      ↓
+3. Activate (ActivateManifestAction)
+      ↓  ← auto-registers declared types into their registries
+4. Active manifest governs the hub's vocabulary
+```
+
+### Step 1 — Create in draft
+
+```
+POST /HubCapabilityManifests/new?hubId=<hub-id>
+```
+
+One manifest per hub (UNIQUE constraint on `hub_id`). Creating a manifest
+for a hub that already has one (in any status) requires retiring the existing
+active manifest first.
+
+### Step 2 — Declare types
+
+While in `draft` status, edit the `declared_*` JSONB arrays. Each array
+contains the string names of types the hub will own:
+
+```json
+{
+  "declared_widget_types": ["dev-pipeline-run", "dev-build-status"],
+  "declared_event_types": ["dev-pipeline-started", "dev-pipeline-failed"],
+  "declared_annotation_categories": ["dev-blocker", "dev-flaky-test"],
+  "declared_policy_scopes": ["dev-internal"]
+}
+```
+
+**Naming convention**: domain-owned types should be prefixed with the domain
+shortcode to prevent collisions (e.g. `dev-`, `fin-`, `sec-`, `ops-`).
+Framework-level types (no prefix) are owned by inter-hub and shared by all hubs.
+
+### Step 3 — Activate
+
+```
+POST /HubCapabilityManifests/ActivateManifest?hubCapabilityManifestId=<id>
+```
+
+On activation:
+- For each name in `declared_widget_types`: insert into `widget_type_registry`
+  with `owner_hub_id = hub.id` if not already present.
+- Same for `declared_event_types`, `declared_annotation_categories`,
+  `declared_policy_scopes`.
+- If any declared name already exists in a registry with a **different**
+  `owner_hub_id`, activation is rejected with a conflict error.
+- If any declared name exists with `owner_hub_id = NULL` (framework-level),
+  activation is rejected: framework types cannot be claimed by a domain hub.
+- `status` is set to `active`, `activated_at` is set to `now()`.
+
+---
+
+## Invariants
+
+1. **Type names are permanent.** Once a type name is registered (either via
+   seed or manifest activation), it cannot be deleted from the registry —
+   only deprecated. Other hubs may already depend on it.
+
+2. **Activated manifests are read-only on declared arrays.** To add new types,
+   retire the manifest and create a new draft, or use `DraftAmendmentAction`
+   which creates an amended draft pending re-activation.
+
+3. **One active manifest per hub.** The UNIQUE constraint on `hub_id` plus the
+   activation workflow enforce this.
+
+4. **Framework types cannot be claimed.** Type names with `owner_hub_id = NULL`
+   are owned by the framework. A domain hub manifest that attempts to declare
+   an existing framework type name is rejected.
+
+---
+
+## Status Lifecycle
+
+```
+draft → active → retired
+              ↓
+           (superseded by a new draft → active cycle)
+```
+
+A retired manifest's types remain in the registry. If the hub is decommissioned,
+the types should be deprecated (not deleted) in the registry.
+
+---
+
+## Failure Modes
+
+| Scenario | Behaviour |
+|---|---|
+| Duplicate type name (same hub) | Idempotent — skipped, not an error |
+| Duplicate type name (different hub) | Activation rejected with conflict error |
+| Framework type name claimed | Activation rejected |
+| Edit of active manifest declared arrays | Rejected — manifest is read-only |
+| Hub with no manifest creates hub-owned type | Warning in fitness function; types accepted but unmanifested |

+# Interaction Reporting API Contract
+
+**Name:** interaction-reporting
+**Version:** 1.0
+**Date:** 2026-03-31
+**Status:** Active
+**Layer:** Functional
+**Maturity:** Stable
+
+---
+
+## Purpose
+
+Defines the REST API surface for external systems (non-IHP adapters, domain
+hubs, third-party tools) to submit interaction events and annotations to the
+IHF without coupling to the IHP server-side implementation.
+
+---
+
+## Canonical Source of Truth
+
+The authoritative runtime contract is the active row in the
+`interaction_reporting_contracts` table. This file is the discoverable
+human-readable declaration. In case of conflict, the database row governs.
+
+---
+
+## Endpoint
+
+```
+POST /api/v1/interaction-events
+```
+
+Authentication: `Authorization: Bearer <hub-api-key>`
+
+The `hub-api-key` must match the `api_key` column of a registered hub.
+
+---
+
+## Required Request Fields
+
+| Field | Type | Description |
+|---|---|---|
+| `widget_id` | UUID | The governed widget's stable ID |
+| `event_type` | TEXT | Must exist in `event_type_registry` with `status = 'active'` |
+| `occurred_at` | ISO 8601 timestamp | When the event occurred on the client |

+
+## Optional Request Fields
+
+| Field | Type | Description |
+|---|---|---|
+| `actor_id` | UUID | The acting user's ID |
+| `actor_type` | TEXT | `user`, `agent`, `automation`, `external_adapter` |
+| `view_context_ref` | TEXT | View path where event occurred |

+```json
+{
+  "error": "Authorization: Bearer <hub-api-key> required"
+}
+```
+

+
+## Accepted Event Types
+
+Accepted event types are all entries in `event_type_registry` with
+`status = 'active'`. The framework-level seed vocabulary:

+`viewed`, `focused`, `clicked`, `submitted`, `abandoned`, `retried`,
+`failed`, `commented`, `flagged_confusing`, `flagged_helpful`,
+`blocked_by_policy`, `escalated`, `accepted_recommendation`,
+`rejected_recommendation`
+
+Domain hubs may register additional event types via `HubCapabilityManifest`.
+
+---
+
+## Versioning Policy
+
+- v1.0: current version. Stable.
+- Adding new optional request fields: minor version (v1.1), no breaking change.
+- Changing required fields, response shape, or auth scheme: major version (v2.0).
+- Phase 9 will introduce `/api/v2/` with OAuth 2.0 replacing per-hub Bearer tokens.
+  v1.0 will remain supported during the migration window.

+**Name:** module-maturity-labels
+**Version:** 1.0
+**Date:** 2026-03-31
+**Status:** Active
+**Layer:** Functional
+
+---
+
+## Purpose
+
+Defines the four maturity states used to label IHF functional modules and
+contract tables. These labels communicate to domain hub developers which
+surfaces are safe to depend on long-term.
+
+---
+
+## Labels
+
+### Stable
+
+The public interface **will not change** within the current major version.
+
+- Removing a field, renaming a table, or changing a column type is a **breaking
+  change** and requires a major version bump (e.g. IHF v1.0 → v2.0).
+- Adding a nullable or defaulted column is **not** breaking and may occur
+  without a version bump, but is documented in the changelog.
+- Suitable for all production use, including domain hub compilation dependencies.
+
+### Beta
+
+The interface is **finalised for typical use** but edge-case fields may change
+with a minor-version notice (e.g. IHF v0.2 → v0.3).
+
+- Core workflow fields are stable; metadata, computed, or supplementary fields
+  may be refined.
+- Suitable for production use with awareness: monitor the changelog before
+  upgrading.
+- A Beta module will be promoted to Stable once it has been used in at least
+  two deployed domain hubs without reported breaking-change issues.
+
+### Experimental
+
+The interface **may change without notice** between patch releases.
+
+- Use only for internal prototyping, spike implementations, or with explicit
+  opt-in acknowledgement.
+- Not suitable for domain hub production code.
+- A module remains Experimental until its design is confirmed by real usage.
+
+### Deprecated
+
+The module or field **will be removed** in the next major version.
+
+- A replacement is documented in the contract or in the schema comment.
+- The deprecated item remains functional until the major version boundary.
+- Domain hubs must migrate before upgrading to the next major version.
+
+---
+
+## Where Labels Are Used
+
+| Surface | How the label is expressed |
+|---|---|
+| Functional modules | `docs/functional-modules.md` maturity column |
+| `envelope_emission_contracts` table | `maturity` column (added in IHUB-WP-0009) |
+| `interaction_reporting_contracts` table | `maturity` column |
+| `widget_adapter_specs` table | `maturity` column |
+| Type registry entries | `status` column (`active` / `deprecated`) |
+| Contract files in `/contracts/` | `Maturity:` header field |
+
+---
+
+## Promotion Path
+
+```
+Experimental → Beta → Stable
+                 ↓
+            Deprecated → (removed at next major version)
+```
+
+Promotions are recorded in the module's entry in `docs/functional-modules.md`
+and the corresponding `maturity` column in the DB is updated.

+# Domain Hub Extension Guide
+
+**Framework:** IHF v0.2 + GAAF-2026 | **Applies to:** Phase 9+ domain hub implementations
+
+This guide is for developers building a new domain hub (dev-hub, ops-hub, fin-hub, sec-hub)
+on top of inter-hub. It covers what the framework provides out of the box, how to register
+your domain's vocabulary, and how to stay compatible across framework upgrades.
+
+---
+
+## What inter-hub Provides
+
+Every domain hub built on inter-hub inherits the following services without any setup:
+
+| Service | What it gives you |
+|---------|------------------|
+| **Event capture** | `POST /api/v1/interaction-events` — record user interactions with a hub API key |
+| **Annotation** | Structured feedback on any widget (friction, defects, wishes, policy concerns) |
+| **Requirement candidates** | Automatic escalation from annotations; triage queue and lifecycle |
+| **Governance ledger** | Decision records, rationale, and approved/rejected outcomes |
+| **AI assistance** | Claude-powered summarization and requirement drafting via AgentProposal |
+| **Deployment + signals** | DeploymentRecord → OutcomeSignal; regression detection |
+| **Observability** | FrictionScore, BottleneckRecord, HubHealthSnapshot |
+| **Federation** | CrossHubPropagation, WidgetOwnership, FederatedPolicyOverlay |
+| **Cross-framework adapters** | EnvelopeEmissionContract, InteractionReportingContract |
+| **Archive + lineage** | Soft-delete with full lineage inspector |
+
+None of these require domain-specific configuration. They are activated as soon as you
+create a `Hub` row and register `Widget` records.
+
+---
+
+## Extension Registration in Three Steps
+
+Domain hubs introduce vocabulary that the framework does not know about at installation
+time: domain-specific widget types (e.g. `dev-pipeline-run`), event types
+(e.g. `fin-budget-alert-dismissed`), annotation categories, and policy scopes.
+
+You **must** register this vocabulary before widgets or events using these names can
+be validated by the framework.
+
+### Step 1 — Create a Hub row
+
+```sql
+-- Via the IHP UI at /hubs/new, or via a migration:
+INSERT INTO hubs (id, name, slug, domain, hub_kind)
+VALUES (uuid_generate_v4(), 'Dev Hub', 'dev-hub', 'dev.example.com', 'domain');
+```
+
+- `hub_kind` must be `'domain'` for bounded domain hubs, or `'shared'` for
+  cross-domain service hubs. `'framework'` is reserved for inter-hub itself.
+- There is exactly one `framework` hub (enforced by a unique partial index).
+
+### Step 2 — Create a HubCapabilityManifest in draft
+
+Navigate to **Extensions → New Manifest** in the inter-hub UI, or via the API:
+
+```
+POST /HubCapabilityManifests (CreateHubCapabilityManifestAction)
+hubId=<your hub id>
+capabilityDescription=Developer toolchain interaction tracking
+contact=platform-team@example.com
+```
+
+In the manifest **Edit** view, declare your type names as JSON arrays:
+
+```json
+// Declared Widget Types
+["dev-pipeline-run", "dev-pr-review", "dev-build-status"]
+
+// Declared Event Types
+["dev-pipeline-triggered", "dev-build-failed", "dev-pr-approved"]
+
+// Declared Annotation Categories
+["dev-flaky-test", "dev-merge-concern"]
+
+// Declared Policy Scopes
+["dev-ci-policy"]
+```
+
+### Step 3 — Activate the manifest
+
+Click **Activate** in the manifest UI, or:
+
+```
+GET /HubCapabilityManifests/{id}/activate (ActivateManifestAction)
+```
+
+On activation, the framework:
+1. Validates that each declared type name is either unregistered or already owned by your hub.
+2. If any name is owned by a different hub, activation is blocked with a conflict message.
+3. If all names are clear, each declared name is inserted into its registry table
+   (`widget_type_registry`, `event_type_registry`, etc.) with `owner_hub_id = your hub id`.
+4. The manifest `status` transitions from `draft` → `active`.
+
+After activation, your types are:
+- **Validated** by all IHF controllers (widgets, annotations, routing rules, API events)
+- **Enumerable** by the Phase 9 OpenAPI specification
+- **Discoverable** by other hubs via the Extensions page
+
+---
+
+## Naming Your Types
+
+| Context | Convention | Example |
+|---------|-----------|---------|
+| **Framework-level types** | No prefix, lowercase-hyphenated | `chart`, `form`, `clicked` |
+| **Domain-owned types** | Prefixed with domain shortcode | `dev-pipeline-run`, `fin-budget-alert` |
+| **Shared hub types** | Prefixed with service shortcode | `state-workstream`, `gov-decision` |
+
+**Rules:**
+- Names are permanent — once registered, they cannot be deleted or renamed.
+  Use `status = 'deprecated'` with a `deprecated_in_favour_of` pointer if you need to
+  transition to a new name.
+- Names are globally unique per registry table. Two hubs cannot own the same name.
+  Use domain prefixes to avoid collisions.
+- Names must be lowercase. Hyphens are preferred over underscores for widget/event types;
+  underscores are accepted for annotation categories and policy scopes.
+
+---
+
+## Using Framework-Level Types
+
+Framework-level types (those with `owner_hub_id IS NULL`) are available to all hubs without
+any registration. You do not need to declare them in your manifest.
+
+Examples of framework-level widget types: `chart`, `form`, `table`, `action`, `panel`, `nav`
+Examples of framework-level event types: `clicked`, `viewed`, `submitted`, `dismissed`, `errored`
+
+Check the Type Registries UI (`/TypeRegistries/WidgetTypes`) to see all active framework types
+before creating domain-specific alternatives.
+
+---
+
+## Cross-Hub Routing
+
+If your domain hub should receive requirement candidates routed from other hubs, configure
+`HubRoutingRule` entries:
+
+```
+POST /HubRoutingRules (CreateHubRoutingRuleAction)
+sourceHubId=<framework hub>
+targetHubId=<your domain hub id>
+matchCategory=dev-flaky-test
+priority=10
+```
+
+The `matchCategory` and `matchWidgetType` fields are validated against their registries.
+You must activate your manifest before creating routing rules that reference your domain types.
+
+---
+
+## Interpreting Maturity Labels
+
+When depending on IHF modules in your domain hub, check `docs/functional-modules.md`
+for the current maturity of each module:
+
+| Maturity | What it means for your hub |
+|----------|--------------------------|
+| **Stable** | Safe to depend on. Breaking changes require a major version bump with migration path. |
+| **Beta** | Core functionality is solid but edge-case fields or computation details may change with a minor-version notice. Suitable for production with awareness. |
+| **Experimental** | Internal prototyping only. May change without notice. Do not build production features on Experimental modules. |
+| **Deprecated** | Will be removed in the next major version. A replacement is documented in the relevant contract file. |
+
+The `maturity` badge is displayed on contract show pages in the inter-hub UI.
+
+---
+
+## FAQ
+
+**Can two hubs declare the same type name?**
+No. Type names are globally unique per registry. Activation order determines ownership.
+If you need a name that another hub owns, coordinate with that hub's contact to either
+share the type (they keep ownership, you use it) or use a domain-prefixed variant.
+
+**Can a type be renamed?**
+No. Names are permanent. To transition: deprecate the old name with `deprecated_in_favour_of`
+pointing to the new name, then register the new name (via a new manifest entry or the
+Type Registry UI).
+
+**Can a hub retire its manifest?**
+Yes. Retiring a manifest sets its status to `retired`; the hub's types remain in registries
+and continue to validate. Retiring is appropriate when a hub is decommissioned or merged.
+Orphaned types (owned by a retired hub's manifest) should be reassigned via the
+Type Registry UI or deprecated.
+
+**Do I need a manifest if I only use framework-level types?**
+No. A manifest is only needed if your hub introduces new type names. If you use only
+existing framework types, you can create widgets and events immediately.
+
+**What if my manifest activation fails with a conflict?**
+The activation endpoint returns the conflicting type names and which hub owns them.
+Either rename your types (before activation; names in a draft manifest can still be changed)
+or coordinate with the owning hub.
+
+**Can I add new types to an active manifest?**
+Currently, activated manifests are read-only on the `declared_*` arrays. The amendment
+workflow is: retire the active manifest, create a new draft, declare all types (old + new),
+activate. A `DraftAmendmentAction` that merges types without retiring is planned for Phase 10.

+---
+
+## Module Details
+
+### RequirementCandidate Lifecycle
+**Phase introduced:** Phase 2
+**Tables:** `requirement_candidates`
+**Stability:** Stable — schema will not change within major version. Validation logic (status transitions: `open → accepted/rejected`) is frozen.
+**Known limitations:** No formal state machine enforcement in the DB; status is TEXT constrained only at the controller layer.
+**Not guaranteed:** The `category` field was previously validated against a hardcoded list; as of GAAF WP-0009 it is validated against `annotation_category_registry`. Applications querying directly may see new category values as the registry grows.
+
+### DecisionRecord + Governance Ledger
+**Phase introduced:** Phase 3
+**Tables:** `decision_records`
+**Stability:** Stable — `requirement_id`, `decided_by`, `decided_at`, `outcome`, `rationale` are permanent.
+**Not guaranteed:** The `outcome_signals` analysis may add new computed fields in `GAAF` analysis helpers.
+
+### DeploymentRecord + OutcomeSignal
+**Phase introduced:** Phase 4
+**Tables:** `deployment_records`, `outcome_signals`
+**Stability:** Stable — `outcome_signals` is append-only (DB trigger enforced). Signal types are an extensible vocabulary.
+**Not guaranteed:** Signal aggregation helpers may change computation logic.
+
+### AgentProposal + Review Workflow
+**Phase introduced:** Phase 5
+**Tables:** `agent_proposals`, `agent_review_records`
+**Stability:** Beta — `proposal_type`, `content`, `model_ref`, `status` are stable. The `confidence` scoring model may be extended with additional fields.
+**Not guaranteed:** Model reference format may evolve as new Claude models are released.
+
+### Cross-Framework Adapter Contracts
+**Phase introduced:** Phase 6
+**Tables:** `envelope_emission_contracts`, `interaction_reporting_contracts`, `widget_adapter_specs`
+**Stability:** Stable — `EnvelopeEmissionContract v1.0` is immutable. New versions are additive and published as new rows.
+**Not guaranteed:** The `maturity` column was added in GAAF WP-0009; existing tooling may not surface this badge.
+
+### FrictionScore + BottleneckRecord
+**Phase introduced:** Phase 7
+**Tables:** `friction_scores`, `bottleneck_records`
+**Stability:** Beta — schema is stable. The `score` computation algorithm in `Application.Helper.FrictionScore` may be tuned without notice.
+**Not guaranteed:** Absolute score values are not stable across algorithm versions; use comparisons within a single version window.
+
+### HubHealthSnapshot
+**Phase introduced:** Phase 7
+**Tables:** `hub_health_snapshots`
+**Stability:** Beta — snapshot schema stable. The composite health score formula may change in Phase 9+ as new signals are added.
+**Not guaranteed:** Historical snapshots retain the score at computation time; they will not be recalculated retroactively.
+
+### CrossHubPropagation
+**Phase introduced:** Phase 7
+**Tables:** `cross_hub_propagations`
+**Stability:** Experimental — pattern detection logic is actively being refined. Schema fields may be renamed or retyped.
+**Not guaranteed:** Detection heuristics, pattern names, and score thresholds will change without notice.
+
+### WidgetOwnership + Routing
+**Phase introduced:** Phase 8
+**Tables:** `widget_ownerships`, `hub_routing_rules`
+**Stability:** Stable — ownership audit pattern (point-in-time `owned_since`/`owned_until`) is permanent. Routing rule schema is stable.
+**Not guaranteed:** As of GAAF WP-0009, `match_category` and `match_widget_type` are now validated against type registries; routing rules using unregistered type names will fail validation.
+
+### FederatedPolicyOverlay
+**Phase introduced:** Phase 8
+**Tables:** `federated_policy_overlays`
+**Stability:** Beta — activation immutability is permanent (activated overlays cannot be edited). The scope model (source/target hub relationships) may extend.
+**Not guaranteed:** Policy overlay conflict detection heuristics may change.
+
+### StewardshipRole
+**Phase introduced:** Phase 8
+**Tables:** `stewardship_roles`
+**Stability:** Stable — the point-in-time role audit pattern is permanent. Role type vocabulary is additive.
+
+### ArchiveRecord + Lineage Inspector
+**Phase introduced:** Phase 8
+**Tables:** `archive_records`
+**Stability:** Beta — soft-delete pattern is stable. Lineage query depth and the `lineage` JSONB structure may be extended.
+**Not guaranteed:** Deep lineage graph queries may become paginated in Phase 9+.
+
+### Type Registries
+**Phase introduced:** GAAF WP-0009
+**Tables:** `widget_type_registry`, `event_type_registry`, `annotation_category_registry`, `policy_scope_registry`
+**Stability:** Beta — schema stable. Framework seed vocabulary is permanent (names cannot be removed, only deprecated). Domain hub vocabulary grows as manifests are activated.
+**Not guaranteed:** Registry UI and bulk import APIs are planned for Phase 10 and will extend the controller surface.
+
+### HubCapabilityManifest
+**Phase introduced:** GAAF WP-0009
+**Tables:** `hub_capability_manifests`
+**Stability:** Beta — activation semantics (draft → active → retired, type auto-registration on activation, read-only after activation) are permanent.
+**Not guaranteed:** The manifest protocol version (`manifest_version` field) will be bumped if the activation semantics change. Amendment workflow (currently manual retire + new draft) may be replaced by a `DraftAmendmentAction` in Phase 10.

+
+*A guideline for building good software systems*
+
+**Good Application Architecture Framework 2026 (GAAF-2026)**  
+**Standards Document**  
+**Version 1.0 – 31 March 2026**
+
+### 1. Introduction
+The **Good Application Architecture Framework 2026 (GAAF-2026)** is a system-theoretic standard for designing, reviewing, and continuously improving software repositories, frameworks, and products. It separates different kinds of change into distinct layers so that rigidity protects stability, malleability enables product learning, extensibility supports controlled growth, and bounded variability keeps operational risk under control.
+
+**One-line doctrine**  
+Freeze the core, evolve the function, bound the customization, constrain the configuration, and govern all change through explicit contracts.
+
+GAAF-2026 turns architecture from an implicit art into a repeatable, measurable, enforceable control system. It is deliberately practical: every concept has an associated artifact, checklist, or automated fitness function that both humans and coding agents can apply immediately. It is designed for immediate adoption in any codebase (monorepo, framework, SaaS, open-source library) and scales across entire organizations.
+
+### 2. Core Concept
+GAAF-2026 views a software system as a **cybernetic control system** for managing change. It evaluates every architectural decision across five orthogonal dimensions:

+
+**Dependency rule (strict)**:  
+Core ← Functional ← Customization ← Configuration  
+Extensions plug into Core or Functional only via contracts.
+
+### 4. Contract System (First-Class Artifact)
+Every compliant repository **MUST** contain a top-level folder:
+
+```
+/contracts/
+  core/
+  functional/
+  customization/
+  config/
+  extensions/
+```
+
+A **Contract** is a versioned artifact that defines for any public surface:
+- Interface
+- Invariants (what must always hold)
+- Compatibility rules
+- Validation rules
+
+Contract types per layer are listed in the table above.
+
+### 5. Architectural Laws (Hard Review Criteria)
+1. Change must occur in the highest appropriate layer.  
+2. Lower layers define contracts; upper layers consume them (downward dependencies only).  
+3. The more rigid the layer, the stronger the interface discipline.  
+4. Variability must be explicit (who, what, guarantees, validation, upgrade path).  
+5. Customer-specific value must not poison product evolution.  
+6. Configuration must never become a second programming language by accident.  
+7. Extensions must use seams, not surgery.  
+8. **Enforcement Law**: All rules above must be automatically verified by architectural fitness functions in CI.
+
+### 6. Evolution Model
+**Promotion path** (rare, bottom-up only)  
+Experiment (Functional) → Stable Functional → Core  
+
+**Extraction path**  
+Functional → Extension (external ownership)  
+
+**Decay path**  
+Functional → Deprecated → Removed  
+
+**Core rule**: Core is never designed top-down; it is distilled from proven Functional patterns that have demonstrated multi-use value.
+
+### 7. Failure Model (Per-Layer Semantics)
+Every contract must explicitly document the failure behaviour for its layer (see table in §3).
+
+### 8. Validation & Architectural Fitness Functions
+Every repository **MUST** implement automated checks:
+- Import / dependency graph validation (no upward dependencies)
+- Core breaking-change detection
+- Config schema validation before any execution
+- Extension manifest + lifecycle hook presence
+- Layer boundary lint rules
+- Demand-signal / cost-justification check for Functional and Customization changes

+### 13. Compliance Definition
+A repository is **GAAF-2026 compliant** if and only if it satisfies **all** of the following:
+1. Layers are separated as defined.
+2. Explicit contracts exist in `/contracts/`.
+3. Strict downward dependency direction is enforced.
+4. Lifecycle states are declared and respected.
+5. Upgradeability is guaranteed via bounded customization.
+6. All user-controlled variability is validated.
+7. Extensibility uses registered, contract-based mechanisms.
+8. Failure is contained within defined per-layer boundaries.
+9. Compliance is continuously measured via scorecard and fitness functions.
+
+### 14. Adoption & Next Steps
+- **For humans**: Use the workplan every major release or when scorecard < 3.5.  
+- **For agents**: Feed this entire document + the `ARCHITECTURE-LAYERS.md` into any coding or review prompt.  
+- **Automation**: Implement the fitness functions listed in §8 as the first CI jobs.  
+- **Repository starter kit**: Create the `/contracts/` folder and `ARCHITECTURE-LAYERS.md` on day one.

 exposes that governance state as a stable, versioned, authenticated REST API and
 ships consumer SDKs that make integration a day's work rather than a project.
 
+### GAAF Foundation Prerequisite
+
+> **IHUB-WP-0009 (GAAF Compliance Foundation) must be complete before Phase 9
+> begins.**
+
+Phase 9 generates an OpenAPI 3.1 specification that documents all IHF API
+fields. Three of those fields — `widget_type`, `event_type`, and `category` —
+are type discriminators. If they are documented as arbitrary `string` values,
+the API contract is immediately incorrect: consumers will invent values that
+diverge from the IHF vocabulary, breaking cross-hub aggregation and federation.
+
+IHUB-WP-0009 establishes the four type registries that enumerate these fields.
+Phase 9 must read from those registries to generate correct `enum` arrays in
+the OpenAPI spec. Building Phase 9 first and retrofitting enums later is a
+breaking API change.
+
+**Specific GAAF dependencies for Phase 9 implementation:**
+
+1. **Type registry enumerations in OpenAPI** — The spec generator must query
+   `widget_type_registry`, `event_type_registry`, and
+   `annotation_category_registry` to produce `enum` arrays for the
+   corresponding fields. The generated spec must NOT document these as
+   unconstrained `string`.
+
+2. **ApiConsumer linked to HubCapabilityManifest** — A `domain` hub
+   authenticating as an API consumer is identified by its active
+   `HubCapabilityManifest`. The `ApiConsumer` record should carry a
+   `hub_capability_manifest_id` FK (nullable — non-hub consumers such as
+   third-party tools authenticate without a manifest). When a manifested
+   consumer submits an event, the `event_type` is validated against both the
+   global `event_type_registry` and the manifest's `declared_event_types`.
+
+3. **OAuth scope alignment with registered vocabulary** — OAuth scopes should
+   include hub-specific scope claims (`hub:{slug}:write`) that the token
+   exchange validates against the hub's active manifest. A consumer without a
+   manifest can only write framework-level event types; hub-owned types require
+   the corresponding hub scope.
+
+4. **Contract file reference** — The OpenAPI spec must reference
+   `/contracts/functional/interaction-reporting-v1.md` as its human-readable
+   companion. The generated spec is derived data; the contract file is
+   authoritative intent.

 ## Phase 10 — Hub Registry and Widget Marketplace
@@ -166,45 +221,105 @@ configurations across deployments. Phase 9 made the IHF externally consumable.
 Phase 10 makes it composable: hubs and widgets can be discovered, rated,
 adopted, and evolved as shared platform assets.
 
+### GAAF Foundation Integration
+
+> **Phase 10's Hub Registry IS the `HubCapabilityManifest` table, extended with
+> a public-facing discovery UI.** It is not a separate data store. IHUB-WP-0009
+> must be complete before Phase 10 begins.
+
+The Hub Registry in Phase 10 is the public-facing projection of the capability
+manifests introduced in IHUB-WP-0009. Every registered hub already has an
+active `HubCapabilityManifest` that declares its widget types, event types,
+annotation categories, and policy vocabulary. Phase 10 adds the browsability,
+pattern publishing, and adoption mechanics on top of that existing foundation.
+
+**Specific GAAF integration points for Phase 10 implementation:**
+
+1. **Hub Registry = active HubCapabilityManifest + HubHealthSnapshot** — The
+   hub registry view is a join of `hub_capability_manifests` (status=active),
+   `hub_health_snapshots` (latest), and `hubs`. No new hub registry table is
+   required. The data already exists; Phase 10 adds the discovery UI.
+
+2. **Widget patterns reference registered types** — A `WidgetPattern` record
+   must declare a `widget_type` that exists in `widget_type_registry`. When
+   publishing a pattern, if the `widget_type` is owned by another hub, the
+   pattern is cross-hub and requires that hub's acknowledgement (or uses a
+   framework-level type). This prevents patterns from encoding unregistered
+   vocabulary.
+
+3. **Pattern adoption triggers manifest update** — When a hub adopts a
+   `WidgetPattern`, if the pattern's `widget_type` is not in the adopting
+   hub's `declared_widget_types`, the adopting hub's manifest is updated to
+   include it (in draft amendment mode). The hub operator must re-activate
+   the amended manifest. This ensures the adopting hub's type vocabulary stays
+   coherent with its actual widget usage.
+
+4. **Governance templates reference registered categories** — A
+   `GovernanceTemplate` for requirement categories must reference entries in
+   `annotation_category_registry`. Template cloning adds any new categories
+   to the cloning hub's manifest (draft amendment).
+
+5. **Hub registry GAAF compliance score** — The hub registry should display
+   each hub's GAAF compliance indicator: whether it has an active manifest,
+   how many registered types it owns, and whether the architecture fitness
+   functions report any violations. This makes GAAF compliance visible as a
+   platform-level metric.

+**Status note (as of 2026-03-31):** key-cape stack (Authelia + LLDAP + privacyIDEA) is deployed and validated on RAILIANCE01 (NK-WP-0003 T01–T08 complete). T09 (backup, DR, monitoring) is the remaining task.
+
+---
+
+## 3. Identity and Security Architecture
+
+### 3.1 Stack Placement
+
+```
+Management Plane (NixOS)              Application Domain (k3s)
+─────────────────────────             ──────────────────────────────────
+LLDAP  ◀── operator accounts only     key-cape:
+Authelia ── OIDC for mgmt services      ├─ LLDAP  (application users)
+                                        ├─ Authelia  (SSO, OIDC broker)
+        optional upstream trust ──────▶ └─ privacyIDEA  (MFA)
+        (cluster Authelia may pull
+         mgmt LLDAP as upstream)
+```
+
+### 3.2 Federation Direction
+
+| Rule | Detail |
+|------|--------|
+| Management → Application | Management plane LLDAP can be registered as an upstream LDAP source in cluster Authelia, so operator accounts get cluster SSO without maintaining two passwords. This is **optional** and the cluster degrades gracefully if the management plane is unreachable. |
+| Application → Management | **Never.** Management-plane services authenticate against the local LLDAP/Authelia only. |
+
+### 3.3 Identity Lifecycle Phases
+
+**Phase 1 — Management-plane IdP, federated outward (current target)**
+
+- Management LLDAP is authoritative for all operator accounts
+- Cluster Authelia federates management LLDAP as upstream for operator SSO
+- Application-only users (if any) have direct accounts in cluster LLDAP
+- Simple, low overhead, suitable for small operator team + small application user population
+
+**Phase 2 — Full application-domain IdP, management users bridged in**
+
+- Triggered when application user population warrants independent governance
+- Cluster LLDAP becomes authoritative for application users
+- Management users are federated into the cluster (not the reverse)
+- Management plane remains fully independent — cluster IdP outage does not affect management operations
+- Migration path is clean because the coupling direction never reverses
+
+### 3.4 Secrets Management
+
+| Domain | Tool | Rationale |
+|--------|------|-----------|
+| Management plane | `agenix` | NixOS-native; age-encrypted secrets declared alongside `configuration.nix`; same age key material as SOPS |
+| Application domain | SOPS/age | Already established in cluster; ArgoCD + Helm secrets operator integration in place |
+| Bridging | Shared age key material | Both tools use age — operator key material can overlap; no second key infrastructure needed |
+
+---
+
+## 4. Operational Boundaries and Failure Modes
+
+### 4.1 Failure Independence
+
+| Failure scenario | Management plane impact | Application domain impact |
+|-----------------|------------------------|--------------------------|
+| Cluster down | None — management plane unaffected | Application workloads down |
+| Management plane down | Governance tooling unavailable | Application workloads continue; SSO may degrade for operator accounts if federation configured (Phase 1 only) |
+| key-cape down | None | Application SSO down; management-plane auth unaffected |
+| Management LLDAP down | Management SSO down | Application SSO degrades for operator accounts (if Phase 1 federation); application users unaffected |
+
+### 4.2 Network Topology
+
+- Management plane has no ingress dependency on the cluster
+- ops-bridge on the management plane provides the entry point for operator traffic to management services
+- Domain hubs (inter-hub instances) communicate with the cluster only via defined capability interfaces — no cluster-internal network access required
+
+---
+
+## 5. Hub and Framework Placement
+
+Inter-hub and all domain hub instances (dev-hub, ops-hub, fin-hub, etc.) run on the management plane, not as cluster workloads. This is a deliberate departure from Option A/C:
+
+- Hub instances are IHP/Haskell — their natural runtime is NixOS + systemd
+- IHP containerisation is non-trivial (Nix OCI build); NixOS systemd is the design target
+- Hubs govern cluster workloads — they must remain available when the cluster is disrupted
+- All hub instances share the same operational paradigm: NixOS configuration, `agenix` secrets, systemd service units
+
+Domain hubs communicate with cluster workloads exclusively through:
+- Registered capability interfaces (state-hub capability registry)
+- HTTPS endpoints (no cluster-internal DNS or service mesh access)
+
+---
+
+## 6. Provisioning Sequence
+
+```
+S0  Workstation (current state)
+    └─ custodian running locally
+    └─ inter-hub in development
+
+S1  Provision management plane host
+    ├─ Terraform null_resource → nixos-anywhere → NixOS install
+    ├─ configuration.nix from inter-hub repo
+    └─ agenix secrets bootstrapped from operator workstation
+
+S2  Migrate custodian to management plane
+    └─ PostgreSQL → management plane (local, NixOS-managed)
+
+S3  Deploy inter-hub + hub instances to management plane
+    └─ systemd services, Authelia + LLDAP for management SSO
+
+S4  Complete key-cape NK-WP-0003 T09 (backup, DR, monitoring)
+    └─ key-cape fully operational in cluster
+
+S5  Configure identity federation (Phase 1)
+    └─ Cluster Authelia registers management LLDAP as upstream
+
+S6  Domain hubs connect to cluster workloads
+    └─ Capability registrations, HTTPS interface contracts
+```

+# IHF GAAF Compliance Foundation
+
+## Goal
+
+Establish inter-hub as a GAAF-2026 compliant framework foundation before any
+domain hub (dev-hub, ops-hub, fin-hub, sec-hub) begins implementation. Close
+the architectural gaps identified in the GAAF review of 2026-03-31 so that
+Phase 9 and beyond are built on a framework with a formal extension layer,
+typed vocabularies, explicit contracts, and CI-enforced architectural boundaries.
+
+## Background
+
+Phases 1–8 are complete. The core traceability chain, federated governance
+machinery, and cross-framework adapter protocol are all production-grade. The
+GAAF-2026 review confirmed the Core layer is strong (3.4/5.0) but revealed
+four critical gaps that must be closed before domain hubs can safely extend
+the framework:
+
+1. **No Extension Layer** — no mechanism for domain hubs to register their
+   widget types, event types, annotation categories, or policy vocabulary
+   with the framework. All type discriminators are unvalidated TEXT, creating
+   vocabulary divergence risk the moment two hubs independently name things.
+
+2. **No `/contracts/` directory or `ARCHITECTURE-LAYERS.md`** — GAAF requires
+   these as living governance artifacts. Their absence means architectural
+   intent is implicit in spec documents and tribal knowledge rather than
+   machine-readable contracts in the repository.
+
+3. **No hub kind classification** — the `hubs` table treats the framework host
+   (inter-hub itself) and domain consumer hubs (dev, ops, fin, sec) as
+   structurally identical. The Phase 10 Hub Registry cannot distinguish
+   providers from consumers without this.
+
+4. **No architectural fitness functions** — architectural constraints exist
+   in the spec but are not automatically verified in CI. Layer boundary
+   violations can accumulate silently.
+
+Reference: `specs/GoodSoftwareArchitectureFramework_2026.md`,
+`specs/InteractionHubFrameworkSpecification_v0.2.md`,
+GAAF review document (2026-03-31 analysis).
+
+## Why This Workplan Precedes Phase 9
+
+Phase 9 exposes the IHF as a versioned external API and generates an OpenAPI
+3.1 specification. That specification must enumerate type discriminators
+(widget_type, event_type, annotation category, policy_scope) as finite enum
+arrays — not arbitrary strings. If the type registries do not exist before
+Phase 9 begins, the OpenAPI spec will document TEXT fields and the API will
+be incorrect by design. The type registries must be stable before the API
+contract is written.
+
+Phase 10 (Hub Registry and Marketplace) is the extension layer in IHF terms.
+Its hub registry IS the `HubCapabilityManifest` table introduced here, scaled
+to a public-facing UI. Building Phase 10 without first establishing the
+manifest schema would require a breaking re-architecture mid-phase.
+
+## GAAF Compliance Targets
+
+After this workplan, inter-hub should score:
+
+| Layer | Before | Target |
+|---|---|---|
+| Core | 3.4 | 3.8 |
+| Functional | 2.2 | 3.2 |
+| Customization | 1.5 | 2.5 |
+| Configuration | 1.6 | 3.0 |
+| Extensions | 0.3 | 3.5 |
+| Cross-layer | 2.3 | 3.5 |
+| **Weighted total** | **2.23** | **~3.3** |
+
+The target moves the framework from "Needs restructuring" (≤2.4) to "Usable
+but vulnerable" (2.5–3.4), clearing the floor for Phase 9+ work. A score of
+≥3.5 (Strong) is the Phase 10 exit target.
+
+## Data Artifacts Introduced
+
+`WidgetTypeRegistry`, `EventTypeRegistry`, `AnnotationCategoryRegistry`,
+`PolicyScopeRegistry`, `HubCapabilityManifest`
+
+Schema additions: `hubs.hub_kind`, maturity columns on existing contract
+tables.
+

+
+## Tasks
+
+### T01 — Governance scaffolding: `/contracts/` and `ARCHITECTURE-LAYERS.md`
+
+```task
+id: IHUB-WP-0009-T01
+status: done
+priority: high
+```
+
+Pure documentation. No schema or code changes. Establishes the governance
+artifacts required by GAAF §4, §9, and §12.
+
+1. Create `/contracts/README.md` — contract catalog listing all contracts by
+   layer, with one-line descriptions and file links. Template:
+
+   ```markdown
+   # IHF Contract Catalog
+   **Framework:** GAAF-2026 | **Last reviewed:** YYYY-MM-DD
+
+   ## Core Contracts
+   - [widget-envelope-v1](core/widget-envelope-v1.md) — Required widget envelope
+     attributes and format rules
+   - [append-only-events-v1](core/append-only-events-v1.md) — Immutability
+     invariant for interaction_events and outcome_signals
+
+   ## Functional Contracts
+   - [interaction-reporting-v1](functional/interaction-reporting-v1.md) — REST
+     API contract for external event and annotation submission
+   - [module-maturity-labels](functional/module-maturity-labels.md) — Definition
+     of Experimental / Beta / Stable / Deprecated for IHF modules
+
+   ## Extensions Contracts
+   - [hub-capability-manifest-v1](extensions/hub-capability-manifest-v1.md) —
+     Domain hub extension registration protocol
+   ```
+
+2. Create `/contracts/core/widget-envelope-v1.md`:
+   - Required `data-*` attributes: `data-widget-id`, `data-hub-id`,
+     `data-view-context`, `data-widget-type`
+   - Optional: `data-capability-ref`, `data-policy-scope`,
+     `data-widget-version`, `data-experiment-variant`
+   - Format rules: `data-widget-id` must be a valid UUID; `data-hub-id` must
+     match a registered hub slug; `data-widget-type` must exist in the
+     `widget_type_registry`
+   - Version: 1.0. Immutable after activation. New requirements → v1.1 with
+     backwards-compatible additions only.
+   - Failure mode: widgets missing required attributes are logged as
+     `malformed_envelope` events; they do not crash the capture pipeline.
+
+3. Create `/contracts/core/append-only-events-v1.md`:
+   - Invariant: `interaction_events` and `outcome_signals` rows are never
+     updated or deleted after insertion.
+   - Enforcement: PostgreSQL triggers `interaction_events_no_update`,
+     `interaction_events_no_delete`, `outcome_signals_no_update`,
+     `outcome_signals_no_delete`.
+   - Correction policy: erroneous events are retracted by inserting a new
+     event of type `retracted` with `metadata.retracted_event_id` pointing
+     to the original. The original row is never modified.
+   - Failure mode: any attempt to UPDATE or DELETE raises a PostgreSQL
+     exception with message "is append-only".
+
+4. Create `/contracts/functional/interaction-reporting-v1.md`:
+   - Summarise the `InteractionReportingContract` DB record as a human and
+     machine-readable contract file. Include endpoint path, accepted event
+     types, required payload fields, auth scheme.
+   - Note: the canonical source of truth is the active
+     `interaction_reporting_contracts` row; this file is the discoverable
+     declaration.
+
+5. Create `/contracts/functional/module-maturity-labels.md`:
+   - **Stable**: public interface will not change within a major version.
+     Removing a Stable field is a breaking change requiring a major version bump.
+   - **Beta**: interface is finalised for typical use but edge-case fields may
+     change with a minor-version notice. Suitable for production with awareness.
+   - **Experimental**: interface may change without notice between patches.
+     Use only for internal prototyping or explicit opt-in.
+   - **Deprecated**: will be removed in the next major version. A replacement
+     is documented in the contract.
+
+6. Create `/contracts/extensions/hub-capability-manifest-v1.md`:
+   - Describes the `HubCapabilityManifest` schema (introduced in T05).
+   - Registration workflow: create manifest in draft → declare types → activate
+     (auto-registers declared types into their registries).
+   - Invariant: once a type name is added to a registry, it cannot be deleted
+     (only deprecated). Names are permanent — hubs may depend on them.
+   - Versioning: manifest_version tracks the protocol version, not the content
+     version. Content changes in draft do not require a version bump; a new
+     active manifest supersedes its predecessor.
+
+7. Create `ARCHITECTURE-LAYERS.md` at the repository root using the GAAF §12.1
+   template. Include:
+   - Layer map: Core (Hub, Widget, WidgetVersion, InteractionEvent, Annotation,
+     traceability chain, append-only invariants, widget envelope) | Functional
+     (RequirementCandidate lifecycle through to FederatedGovernance) |
+     Customization (HubRoutingRule, FederatedPolicyOverlay — hub-specific
+     routing and policy) | Configuration (hub_kind, policy_scope, hub api_key,
+     HubCapabilityManifest) | Extensions (HubCapabilityManifest + type
+     registries — domain hub vocabulary registration)
+   - Dependency rule diagram
+   - GAAF weighted scorecard (initial values from 2026-03-31 review)
+   - Next review date: 2026-09-30
+
+**Exit criteria:** `/contracts/` exists with six contract files; `README.md`
+catalogs all of them; `ARCHITECTURE-LAYERS.md` exists at root with layer map
+and scorecard filled in.
+
+---
+
+### T02 — Hub kind: classify hubs as `framework | domain | shared`
+
+```task
+id: IHUB-WP-0009-T02
+status: done
+priority: high
+```
+
+Adds the structural distinction between inter-hub (the framework host) and
+domain consumer hubs. Required by Phase 10 Hub Registry and by any fitness
+function that checks "all domain hubs have an active capability manifest".
+
+1. Schema addition:
+
+   ```sql
+   -- hub_kind: structural role of the hub within the framework
+   -- 'framework' = inter-hub itself; there is exactly one framework hub
+   -- 'domain'    = a bounded domain consumer (dev-hub, ops-hub, fin-hub, sec-hub)
+   -- 'shared'    = a cross-domain service hub (state-hub, governance-hub)
+   ALTER TABLE hubs
+       ADD COLUMN hub_kind TEXT NOT NULL DEFAULT 'domain';
+
+   CREATE INDEX hubs_hub_kind_idx ON hubs (hub_kind);
+
+   -- Constraint: only one framework hub at a time
+   CREATE UNIQUE INDEX hubs_one_framework_idx ON hubs (hub_kind)
+       WHERE hub_kind = 'framework';
+   ```
+
+2. Write and run migration.
+
+3. If a hub row representing inter-hub itself exists (slug = 'inter-hub' or
+   equivalent), update it: `UPDATE hubs SET hub_kind = 'framework' WHERE
+   slug = 'inter-hub'`. If no such row exists, this is a documentation-only
+   concern — add a note in `ARCHITECTURE-LAYERS.md`.
+
+4. Validation in `HubsController`:
+   - `hub_kind` must be one of `framework | domain | shared`
+   - `framework` kind cannot be set via the web UI (read-only in forms;
+     only settable via migration or seeding)
+   - Default for new hubs created through the UI: `domain`
+
+5. Hub list view: add a kind badge column (framework=purple, domain=blue,
+   shared=teal). Hub show page: kind badge in the header.
+
+6. Hub index: add a tab filter for kind (All / Framework / Domain / Shared).
+
+**Exit criteria:** migration runs; hub kind badge renders correctly;
+constraint prevents a second `framework` hub; new hubs default to `domain`.
+

+
+### T03 — Type registries: registered vocabularies for widget type, event type, annotation category, and policy scope
+
+```task
+id: IHUB-WP-0009-T03
+status: done
+priority: high
+```
+
+This is the most consequential task in the workplan. These four registries
+replace the implicit, unvalidated TEXT vocabularies that all type
+discriminators currently rely on. They are the foundation for both the
+Phase 9 OpenAPI enumerations and the Phase 10 marketplace's type-safe
+widget patterns.
+
+1. Schema — four registry tables:
+
+   ```sql
+   -- widget_type_registry: registered widget types
+   CREATE TABLE widget_type_registry (
+       id UUID DEFAULT uuid_generate_v4() PRIMARY KEY NOT NULL,
+       name TEXT NOT NULL UNIQUE,
+       -- canonical identifier: lowercase-hyphenated, e.g. 'pipeline-status'
+       label TEXT NOT NULL,
+       description TEXT,
+       owner_hub_id UUID REFERENCES hubs(id),
+       -- null = framework-level type (cross-domain); non-null = domain-owned
+       status TEXT NOT NULL DEFAULT 'active',
+       -- 'active' | 'deprecated'
+       deprecated_in_favour_of TEXT,
+       -- name of the replacement type, if deprecated
+       created_at TIMESTAMP WITH TIME ZONE DEFAULT now() NOT NULL
+   );
+
+   CREATE INDEX widget_type_registry_status_idx
+       ON widget_type_registry (status);
+   CREATE INDEX widget_type_registry_owner_hub_idx
+       ON widget_type_registry (owner_hub_id);
+
+   -- event_type_registry: registered interaction event types
+   CREATE TABLE event_type_registry (
+       id UUID DEFAULT uuid_generate_v4() PRIMARY KEY NOT NULL,
+       name TEXT NOT NULL UNIQUE,
+       label TEXT NOT NULL,
+       description TEXT,
+       owner_hub_id UUID REFERENCES hubs(id),
+       status TEXT NOT NULL DEFAULT 'active',
+       deprecated_in_favour_of TEXT,
+       created_at TIMESTAMP WITH TIME ZONE DEFAULT now() NOT NULL
+   );

+       description TEXT,
+       owner_hub_id UUID REFERENCES hubs(id),

+   );
+
+   CREATE INDEX policy_scope_registry_status_idx
+       ON policy_scope_registry (status);
+   ```
+
+2. Seed the framework-level vocabulary (owner_hub_id = NULL):
+
+   **Widget types** (from IHF spec §6.2 and existing usage):
+   `chart`, `form`, `table`, `action`, `panel`, `workflow-step`,
+   `recommendation`, `chat`, `diff`
+
+   **Event types** (from IHF spec §6.4):
+   `viewed`, `focused`, `clicked`, `submitted`, `abandoned`, `retried`,
+   `failed`, `commented`, `flagged_confusing`, `flagged_helpful`,
+   `blocked_by_policy`, `escalated`, `accepted_recommendation`,
+   `rejected_recommendation`
+
+   **Annotation categories** (from schema defaults and IHF spec §6.6):
+   `friction`, `missing_capability`, `policy_conflict`, `trust_deficit`,
+   `accessibility`, `workflow_bottleneck`, `documentation_gap`,
+   `product_opportunity`, `governance_concern`
+
+   **Policy scopes** (from existing usage):
+   `internal`, `org-wide`, `external`, `regulatory`, `security`
+
+3. Scaffold `TypeRegistriesController` (single controller for all four
+   registries, scoped by `registry` parameter):
+   - `index { registry }`: table of all entries for the given registry —
+     name, label, owner hub (or "Framework"), status badge, created at
+   - `show { registry, id }`: full detail including deprecated_in_favour_of
+   - `new { registry }` / `create`: add a new type. `owner_hub_id` defaults
+     to the current user's hub (if applicable). Framework-level entries
+     (owner_hub_id = NULL) are restricted to admin users.
+   - `DeprecateTypeAction { registry, id }`: sets `status = 'deprecated'`,
+     requires `deprecated_in_favour_of` to be set. No delete — names are
+     permanent.
+   - No edit of `name` after creation (names are permanent identifiers).
+     Label and description are editable.
+
+4. Link "Type Registries" from global nav (admin section).
+
+5. Framework-level type entries are pre-seeded by the migration and not
+   creatable via the UI without admin privileges. Hub-owned types are
+   created by any authenticated user.
+
+**Exit criteria:** all four registry tables exist; framework vocabulary is
+seeded; CRUD UI works; deprecation works; name edits are blocked; registry
+index is accessible from nav.

+
+### T04 — Registry-backed validation: type discriminators checked against registries in controllers
+
+```task
+id: IHUB-WP-0009-T04
+status: done
+priority: high
+```
+
+Wire the four type registries (T03) into the controllers that create records
+using type discriminator fields. This transforms the registries from
+documentation artifacts into enforced contracts.
+
+Also adds `maturity` to the three existing contract tables so that
+functional module stability is machine-readable.
+
+**Controller validations to add:**
+
+1. `WidgetsController` — `CreateWidgetAction` and `UpdateWidgetAction`:
+   - Validate `widget_type` exists in `widget_type_registry` with
+     `status = 'active'`
+   - Validate `policy_scope` exists in `policy_scope_registry` with
+     `status = 'active'`
+   - Error message format: "Widget type 'X' is not registered. Register it
+     in the Type Registry or choose an existing type."
+   - Widget `new` and `edit` forms: replace `widget_type` free-text input
+     with a `<select>` populated from `widget_type_registry` (active entries
+     first; framework-level types at top, hub-owned below a divider).
+     Same for `policy_scope`.
+
+2. `InteractionEventsController` and `ApiInteractionEventsController` —
+   `CreateInteractionEventAction`:
+   - Validate `event_type` exists in `event_type_registry` with
+     `status = 'active'`
+   - The API controller returns HTTP 422 with
+     `{"error": "event_type 'X' not registered"}` if validation fails.
+   - New/create form and API docs: enumerate active event types.
+
+3. `AnnotationsController` — `CreateAnnotationAction`:
+   - Validate `category` exists in `annotation_category_registry` with
+     `status = 'active'`
+   - Annotation `new` form: replace `category` text input with `<select>`.
+
+4. `HubRoutingRulesController` — `CreateHubRoutingRuleAction` and
+   `UpdateHubRoutingRuleAction`:
+   - If `match_widget_type` is set, validate it exists in
+     `widget_type_registry`
+   - If `match_category` is set, validate it exists in
+     `annotation_category_registry`
+
+5. Add a shared validation helper in `Application/Helper/TypeRegistry.hs`:
+
+   ```haskell
+   -- Returns Right () if the name is registered and active; Left error otherwise.
+   validateRegisteredType ::
+       (?modelContext :: ModelContext) =>
+       Text -> Text -> IO (Either Text ())
+   validateRegisteredType registryTable name = ...
+   ```
+
+   Use this helper from all four controllers above.
+
+**Maturity on existing contract tables:**
+
+```sql
+-- Add maturity tracking to existing contract tables (T04)
+ALTER TABLE envelope_emission_contracts
+    ADD COLUMN maturity TEXT NOT NULL DEFAULT 'stable';
+
+ALTER TABLE interaction_reporting_contracts
+    ADD COLUMN maturity TEXT NOT NULL DEFAULT 'stable';
+
+ALTER TABLE widget_adapter_specs
+    ADD COLUMN maturity TEXT NOT NULL DEFAULT 'beta';
+-- existing adapter specs are beta until explicitly promoted
+```
+
+Valid values: `experimental | beta | stable | deprecated`
+(consistent with `/contracts/functional/module-maturity-labels.md`).
+
+Show maturity badge on the show views for each contract table.
+
+**Exit criteria:** creating a widget with an unregistered `widget_type`
+returns a validation error; creating an interaction event with an
+unregistered `event_type` returns a validation error (web and API);
+creating an annotation with an unregistered `category` returns a validation
+error; widget and annotation forms render as select dropdowns; maturity
+columns exist and render badges on contract show pages.

+
+### T05 — HubCapabilityManifest: domain hub extension registration
+
+```task
+id: IHUB-WP-0009-T05
+status: done
+priority: high
+```
+
+Introduces the GAAF Extensions layer: a formal mechanism for domain hubs to
+declare the vocabulary they contribute to the framework. This is the central
+artifact for the extension registration goal. Phase 10's Hub Registry will
+build its public-facing UI directly on top of this table.
+
+1. Schema:
+
+   ```sql
+   -- HubCapabilityManifest: a domain hub's declaration of the types it
+   -- introduces and the capabilities it governs.
+   CREATE TABLE hub_capability_manifests (
+       id UUID DEFAULT uuid_generate_v4() PRIMARY KEY NOT NULL,
+       hub_id UUID NOT NULL UNIQUE REFERENCES hubs(id),
+       manifest_version TEXT NOT NULL DEFAULT '1.0',
+       -- protocol version of the manifest format, not the hub's content version
+       declared_widget_types JSONB NOT NULL DEFAULT '[]',
+       -- array of type names referencing widget_type_registry
+       declared_event_types JSONB NOT NULL DEFAULT '[]',
+       declared_annotation_categories JSONB NOT NULL DEFAULT '[]',
+       declared_policy_scopes JSONB NOT NULL DEFAULT '[]',
+       capability_description TEXT,
+       -- human-readable summary of what this hub governs
+       contact TEXT,
+       -- team / person responsible for this hub's vocabulary
+       status TEXT NOT NULL DEFAULT 'draft',
+       -- 'draft' | 'active' | 'retired'
+       activated_at TIMESTAMP WITH TIME ZONE,
+       created_at TIMESTAMP WITH TIME ZONE DEFAULT now() NOT NULL,
+       updated_at TIMESTAMP WITH TIME ZONE DEFAULT now() NOT NULL
+   );
+
+   CREATE INDEX hub_capability_manifests_hub_id_idx
+       ON hub_capability_manifests (hub_id);
+   CREATE INDEX hub_capability_manifests_status_idx
+       ON hub_capability_manifests (status);
+   ```
+
+2. Activation semantics (the critical business logic):
+   On `ActivateManifestAction { hubCapabilityManifestId }`:
+   - For each name in `declared_widget_types`: insert into
+     `widget_type_registry (name, owner_hub_id)` if not already present.
+     If the name exists with a different `owner_hub_id`, return a validation
+     error: "Type 'X' is already owned by hub Y. Coordinate with that hub
+     to share or rename."
+   - Same for `declared_event_types`, `declared_annotation_categories`,
+     `declared_policy_scopes`.
+   - Set `status = 'active'`, `activated_at = now()`.
+   - Once active, `declared_*` arrays are read-only. To add new types, the
+     hub operator amends the manifest: creates a new `draft` record
+     (the unique constraint is per `hub_id`, so the active record must be
+     retired first) or the update goes via a `DraftAmendmentAction` that
+     merges new types into the active manifest with a review step.
+   - A hub with `hub_kind = 'domain'` should have an active manifest before
+     it creates any hub-owned type registry entries. This is enforced as a
+     warning (not a hard block) in the activation flow.
+
+3. Scaffold `HubCapabilityManifestsController`:
+   - `index`: table of all manifests — hub name, kind badge, status badge,
+     declared type counts (widget / event / category / policy), activated at
+   - `show { id }`: full detail — hub info, all declared type arrays with
+     links to their registry entries, activation history, contact
+   - `new { hubId }` / `create`: creates a draft manifest for a hub.
+     One manifest per hub (unique constraint); if a draft exists, redirect
+     to `edit`.
+   - `edit` / `update`: edit draft manifest fields. Active manifests are
+     read-only except via `DraftAmendmentAction`.
+   - `ActivateManifestAction { id }`: runs the activation workflow above.
+   - `RetireManifestAction { id }`: sets `status = 'retired'`. The hub's
+     types remain in the registry but the manifest is no longer current.
+
+4. Hub show page: add "Capability Manifest" section — status badge (No
+   manifest / Draft / Active / Retired), declared type summary, link to
+   manifest show page, "Register Capabilities" button if no active manifest.
+
+5. Link "Extensions" from global nav (lists all active manifests).
+
+**Exit criteria:** manifest can be created in draft; activation registers all
+declared types into registries; name conflict during activation returns an
+error; activated manifest is read-only on declared types; hub show page
+displays manifest status; extensions nav entry renders all active manifests.

+### T06 — Functional module maturity documentation and domain hub extension guide
+
+```task
+id: IHUB-WP-0009-T06
+status: done
+priority: medium
+```
+
+Documentation tasks that complete the GAAF Functional and Extensions layer
+requirements. No schema changes.
+
+1. Create `docs/functional-modules.md` — the authoritative maturity register
+   for all IHF functional modules:
+
+   | Module | Phase introduced | Maturity | Stability guarantee | Deprecation policy |
+   |--------|-----------------|----------|--------------------|--------------------|
+   | RequirementCandidate lifecycle | Phase 2 | Stable | Schema and controller API frozen | Major version only |
+   | DecisionRecord + governance ledger | Phase 3 | Stable | Schema and controller API frozen | Major version only |
+   | DeploymentRecord + OutcomeSignal | Phase 4 | Stable | Append-only invariant permanent | Major version only |
+   | AgentProposal + review workflow | Phase 5 | Beta | Core fields stable; confidence model may extend | Minor version notice |
+   | Cross-framework adapter contracts | Phase 6 | Stable | EnvelopeEmissionContract v1.0 immutable | Superseding contract only |
+   | FrictionScore + BottleneckRecord | Phase 7 | Beta | Computation algorithm may improve | Minor version notice |
+   | HubHealthSnapshot | Phase 7 | Beta | Snapshot schema stable; score formula may change | Minor version notice |
+   | CrossHubPropagation | Phase 7 | Experimental | Pattern detection logic evolving | No notice |
+   | WidgetOwnership + routing | Phase 8 | Stable | Ownership audit pattern permanent | Major version only |
+   | FederatedPolicyOverlay | Phase 8 | Beta | Activation immutability permanent; scope model may extend | Minor version notice |
+   | StewardshipRole | Phase 8 | Stable | Point-in-time audit pattern permanent | Major version only |
+   | ArchiveRecord + lineage inspector | Phase 8 | Beta | Soft-delete pattern stable; lineage query may deepen | Minor version notice |
+   | Type registries (this workplan) | GAAF | Beta | Schema stable; seed vocabulary may expand | Additive only |
+   | HubCapabilityManifest (this workplan) | GAAF | Beta | Activation semantics stable; manifest protocol may version | Minor version notice |
+
+   For each module: also document known limitations and what is NOT
+   guaranteed.
+
+2. Create `docs/domain-hub-extension-guide.md` — the integration guide for
+   developers building a new domain hub (dev-hub, ops-hub, etc.):
+
+   Sections:
+   - **What inter-hub provides** — the framework services a domain hub
+     inherits without any setup (event capture, annotation, requirements,
+     governance, AI assistance, observability, federation)
+   - **Extension registration in three steps**:
+     1. Create a hub row with `hub_kind = 'domain'`
+     2. Create a `HubCapabilityManifest` in draft — declare widget types,
+        event types, annotation categories, policy scopes your domain
+        introduces
+     3. Activate the manifest — your types are now registered and validated
+        by the framework
+   - **Naming your types** — conventions: lowercase-hyphenated, prefixed
+     with domain shortcode where collision-prone (e.g. `dev-pipeline-run`,
+     `fin-budget-alert`, `sec-vuln-widget`). Framework-level types have no
+     prefix.
+   - **Using framework-level types** — no registration needed; any active
+     framework type is available to all hubs
+   - **Cross-hub routing** — how to configure `HubRoutingRule` entries so
+     cross-domain candidates route correctly to your hub
+   - **What changes between upgrades** — how to interpret the maturity
+     labels; Stable = safe to depend on; Beta = upgrade-aware; Experimental
+     = internal use only
+   - **FAQ**: Can two hubs declare the same type name? (No — activate order
+     determines ownership; coordinate with the owning hub to share.) Can a
+     type be renamed? (No — deprecated and replaced by a new name.) Can a
+     hub retire its manifest? (Yes — its types remain in registries but are
+     orphaned; reassign ownership or deprecate them.)
+
+**Exit criteria:** `docs/functional-modules.md` exists with all modules
+listed; `docs/domain-hub-extension-guide.md` exists with all three
+registration steps and naming conventions covered.

+
+### T07 — Architectural fitness functions in CI
+
+```task
+id: IHUB-WP-0009-T07
+status: done
+priority: medium
+```
+
+Implements the GAAF §8 requirement for automated architectural verification.
+Adds a `Test/Architecture/` test module that runs as part of the standard
+`test` command.
+
+1. Create `Test/Architecture/LayerBoundarySpec.hs`:
+
+   **Test 1 — Core immutability contract presence**:
+   Assert that `Application/Schema.sql` contains the four trigger names that
+   enforce append-only semantics:
+   - `interaction_events_no_update`
+   - `interaction_events_no_delete`
+   - `outcome_signals_no_update`
+   - `outcome_signals_no_delete`
+   Failure message: "Core append-only invariant trigger missing from schema."
+
+   **Test 2 — Contract artifact presence**:
+   Assert that the following files exist (filesystem check):
+   - `/contracts/README.md`
+   - `/contracts/core/widget-envelope-v1.md`
+   - `/contracts/core/append-only-events-v1.md`
+   - `ARCHITECTURE-LAYERS.md`
+   Failure message: "GAAF contract artifact missing: {path}. See
+   ARCHITECTURE-LAYERS.md §Compliance."
+
+   **Test 3 — Type registry non-empty**:
+   Query `widget_type_registry`, `event_type_registry`,
+   `annotation_category_registry`, `policy_scope_registry`. Assert each
+   table has ≥1 active entry.
+   Failure message: "Type registry {table} has no active entries. Seed the
+   framework vocabulary before running tests."
+
+   **Test 4 — No bare TEXT type discriminators in new migrations**:
+   Read `Application/Schema.sql`. For any column named `widget_type`,
+   `event_type`, `category`, or `policy_scope` added after a specific marker
+   comment `-- GAAF: type registries enforced from here`, assert the column
+   definition includes a `REFERENCES` or `CHECK` constraint.
+   Failure message: "Column {col} in {table} uses bare TEXT for a type
+   discriminator. Reference a registry table or add a CHECK constraint."
+
+   **Test 5 — Domain hub manifest coverage** (warning, not failure):
+   Query all `hubs` rows with `hub_kind = 'domain'`. For each, check that a
+   `hub_capability_manifests` record exists with `status = 'active'`.
+   Log a warning (not a test failure): "Domain hub '{slug}' has no active
+   capability manifest. Register its types via the Extension Registry before
+   adding hub-owned type discriminators."
+
+2. Register `Test/Architecture/LayerBoundarySpec.hs` in the test suite
+   (`Test/Main.hs`).
+
+3. Add marker comment to `Application/Schema.sql` after the last Phase 8
+   migration block:
+
+   ```sql
+   -- GAAF: type registries enforced from here (IHUB-WP-0009)
+   -- All new type discriminator columns (widget_type, event_type, category,
+   -- policy_scope) must reference a registry table or carry a CHECK constraint.
+   ```
+
+**Exit criteria:** `test` includes the architecture spec; Tests 1–3 pass
+against a fresh database with seed data; Test 4 passes against the current
+schema; Test 5 produces no warnings for a DB with a seeded framework hub and
+no domain hubs yet.

+
+### T08 — GAAF gate: scorecard, consistency, documentation updates
+
+```task
+id: IHUB-WP-0009-T08
+status: done
+priority: high
+```
+
+Closes the workplan, validates GAAF compliance targets, and prepares the
+repository for Phase 9.
+
+1. **Update `ARCHITECTURE-LAYERS.md` scorecard** with post-workplan scores.
+   Fill in the actual weighted total and compare against targets from this
+   workplan's Background section. Document any criteria that remain below
+   target and why.
+
+2. **Update `SCOPE.md`**:
+   - Current state: add "GAAF compliance foundation complete (IHUB-WP-0009);
+     type registries, extension manifests, architectural contracts, and
+     fitness functions in place"
+   - Upstream dependencies: update hub-core reference to note that
+     `HubCapabilityManifest` in inter-hub now provides the DB-side of
+     capability registration; hub-core (when implemented) will provide the
+     shared Haskell library that domain hubs compile against.
+
+3. **Update `CLAUDE.md`**:
+   - Active workplan: change from IHUB-WP-0005 to IHUB-WP-0010 (Phase 9)
+   - Add "GAAF compliance" context block noting that type registries must be
+     kept seeded and all new type discriminator columns must reference a
+     registry
+   - Add reference to `docs/domain-hub-extension-guide.md` as the entry
+     point for new domain hub developers
+
+4. **State Hub consistency sync**:
+   `check_repo_consistency(repo_slug="inter-hub", fix=True)`
+
+5. **Integration tests** (`Test/`):
+   - `HubCapabilityManifest` create in draft + activate + verify type
+     auto-registration in registries
+   - Activation conflict: two hubs declaring the same type name → second
+     activation returns a conflict error
+   - Widget create with unregistered type → validation error
+   - Widget create with registered type → success
+   - InteractionEvent create via API with unregistered event_type → 422
+   - Annotation create with unregistered category → validation error
+   - Architecture spec tests pass (T07)
+
+6. **Smoke test checklist**:
+   - Create a hub with `hub_kind = 'domain'`; verify kind badge
+   - Open Type Registries nav; verify all four registries have seeded entries
+   - Create a widget with an unregistered `widget_type`; verify error
+   - Register a new widget type via the Type Registry admin UI; retry widget
+     creation → success
+   - Create a `HubCapabilityManifest` for the domain hub in draft; add two
+     custom widget types; activate → verify types appear in registry with
+     correct `owner_hub_id`
+   - Attempt to activate a second hub's manifest using the same type name →
+     verify conflict error
+   - Open Extensions nav; verify active manifest is listed
+   - Hub show page: verify "Capability Manifest" section shows active status
+   - Run `test`; verify architecture spec tests pass with no warnings
+
+**Exit criteria:** all integration tests pass; smoke test completed without
+errors; `ARCHITECTURE-LAYERS.md` scorecard shows weighted total ≥3.1;
+`SCOPE.md` and `CLAUDE.md` updated; State Hub consistency sync reports no
+errors.

+
+## Phase 9 Readiness Checklist
+
+The following must be true before IHUB-WP-0010 (Phase 9) begins:
+
+- [ ] All four type registries are seeded with framework vocabulary
+- [ ] All type discriminator TEXT columns are validated against registries in controllers
+- [ ] `HubCapabilityManifest` table exists and the activation workflow is operational
+- [ ] `/contracts/` contains at minimum `core/widget-envelope-v1.md`,
+      `core/append-only-events-v1.md`, `functional/interaction-reporting-v1.md`,
+      and `extensions/hub-capability-manifest-v1.md`
+- [ ] `ARCHITECTURE-LAYERS.md` exists and is current
+- [ ] Architecture fitness functions pass in CI
+- [ ] `ARCHITECTURE-LAYERS.md` weighted scorecard is ≥3.1
+
+## Notes
+
+- **Type names are permanent.** Once a name enters a registry (whether via
+  seed or manifest activation), it cannot be deleted — only deprecated. Build
+  the seeded vocabulary carefully. Domain hub names should use a
+  domain-shortcode prefix where collision is likely (see extension guide).
+
+- **Manifests are the domain hub's identity contract.** A domain hub that has
+  not activated a manifest is an unregistered participant. It can still create
+  hubs and widgets (the framework permits it) but its types are not validated,
+  not namespaced, and not discoverable in Phase 10's marketplace.
+
+- **This workplan does not split the shared PostgreSQL schema.** Domain
+  isolation at the database level (separate schemas or RLS) is a Phase 9+
+  concern. This workplan establishes the vocabulary-level isolation needed
+  before physical isolation decisions are made.
+
+- **hub-core remains a future concern.** The Haskell shared library for domain
+  hub bootstrapping is planned but not blocked on this workplan.
+  `HubCapabilityManifest` provides the DB-side registration contract.
+  hub-core, when implemented, will provide the compile-time Haskell types
+  that correspond to a hub's declared vocabulary. The two are complementary,
+  not redundant.
