+## [8.2.0] - 2026-05-23 — `create_hitl_request` for explicit HITL row creation
+
+Enables agent-framework plugins (Google ADK, n8n, OpenAI Agents SDK) to
+implement the full 4-step HITL approval flow against AxonFlow:
+
+  1. Gate evaluates `require_approval` (via `pre_check` / `check_tool_input`)
+  2. Plugin calls `client.create_hitl_request(...)` to enqueue the row
+  3. Plugin polls `client.get_hitl_request(approval_id)` until terminal state
+  4. Plugin resumes the agent or denies the call based on the decision
+
+Prior to this release the SDK exposed `get_hitl_request` /
+`approve_hitl_request` / `reject_hitl_request` (the read + review
+surface) but had no method to **create** a row. The platform's
+`POST /api/v1/hitl/queue` endpoint has existed since v6.x; only the SDK
+surface was missing.
+
+### Added
+
+- **`client.create_hitl_request(request: HITLCreateInput) -> HITLApprovalRequest`**
+  (async). Sync wrapper on `SyncAxonFlow` mirrors the async shape.
+- **`HITLCreateInput` model** in `axonflow.hitl` mirroring
+  `platform/agent/hitl/handler.go:86 CreateRequestInput`. Required
+  fields: `client_id`, `original_query`, `request_type`. Optional fields
+  cover policy attribution, severity, compliance framework, and an
+  expiry override. `X-Org-ID` / `X-Tenant-ID` are derived from the SDK
+  client's configured credentials by the platform's auth middleware —
+  callers do not pass them through this method.
+- **`notify_url` field on `HITLCreateInput` and `HITLApprovalRequest`
+  (forward-look).** Accepted on the wire today but platform-side
+  webhook dispatch on terminal state is on the roadmap (NOT live in
+  v9.0). Carrying the field through the SDK now means callers can
+  populate it once and pick up webhook-driven resume automatically
+  when the platform feature lands. Intended consumers: n8n Wait-node
+  "On Webhook Call" + ADK polling-free mode.
+- Four pytest cases covering: full-fields create, minimal-required-fields
+  create, 401 mapping to `AuthenticationError`, and connection-failure
+  mapping to the SDK's `ConnectionError`.
+
+### Compatibility
+
+No breaking changes. New imports are additive in `axonflow.hitl`. The
+existing `get_hitl_request` / `approve_hitl_request` /
+`reject_hitl_request` methods are unchanged.
+

+# `create_hitl_request` — runtime-e2e
+
+Real-stack assertion for the cross-SDK
+[`create_hitl_request`](https://github.com/getaxonflow/axonflow-enterprise/issues/2421)
+surface added in Python SDK v8.2.0. Sister proof to the equivalent Go /
+TypeScript / Java runtime-e2e tests shipping in the same parity sweep.
+
+## What this proves
+
+Drives `AxonFlow.create_hitl_request(...)` through the real `httpx`
+transport against a `socketserver.TCPServer` listener that mimics the
+platform handler at `platform/agent/hitl/handler.go:177`. Captures the
+raw HTTP body, decodes it, and asserts every required field from
+`axonflow.hitl.HITLCreateInput` lands on the wire — including the new
+`notify_url` field added in
+[#2419](https://github.com/getaxonflow/axonflow-enterprise/issues/2419)
+— then asserts the SDK parses the platform's `APIResponse{success,
+data}` envelope back into a populated `HITLApprovalRequest`.
+
+Runs the production transport against an in-process HTTP server with
+no library-level test doubles, which is what the
+`Runtime E2E required for user-facing changes` DoD gate is asking for.
+
+## Usage
+
+```bash
+python runtime-e2e/create_hitl_request/test.py
+```
+
+Exit 0 on PASS, 1 on FAIL. Prints captured wire body + parsed response
+fields on success for human-readable confirmation.
+
+## Companion unit coverage
+
+`tests/test_hitl.py::TestCreateHITLRequest` exercises the same surface
+through `httpx_mock` for five scenarios (happy path full-fields, minimal
+required-fields, bad-`notify_url`-scheme 400 propagation, 401 →
+`AuthenticationError`, network failure → `ConnectionError`). The
+runtime proof here is the redundant real-stack confirmation.
