+# PRD: FU-P13-T17 — Enable broker-hosted Web UI with shared multi-client telemetry
+
+## 1. Objective
+
+Deliver a single-host broker topology where one long-lived broker process can also host the Web UI dashboard and expose telemetry aggregated across all broker-connected agents. This closes the current behavior gap where broker paths are transport-only and do not start dashboard services.
+
+The implementation must support:
+- `--broker-daemon --web-ui [--web-ui-config|--web-ui-port]` in one process
+- `--broker-spawn --web-ui ...` propagating Web UI args to the spawned daemon host
+- broker-side telemetry recording for `initialize` and `tools/call` lifecycles so all broker clients appear in one metrics/audit stream
+
+## 2. Success Criteria and Acceptance Tests
+
+### Success Criteria
+- Broker daemon can start Web UI server when requested without entering direct-mode bridge loop.
+- Auto-spawn proxy can bootstrap a broker host with Web UI enabled from the same client config.
+- Shared dashboard reflects tool requests/responses from multiple broker clients.
+- Existing direct-mode and broker-only behavior remains backward compatible.
+
+### Acceptance Tests
+- Unit test: `main()` broker-daemon + `--web-ui` starts server thread and wires telemetry store into broker transport.
+- Unit test: `main()` broker-spawn + `--web-ui` passes spawn args to `BrokerProxy` and includes Web UI flags.
+- Unit test: `UnixSocketServer` records request/response telemetry and client identity on broker-routed traffic.
+- Regression: existing broker tests and Web UI tests remain green.
+
+## 3. Test-First Plan
+
+1. Add failing unit tests first for new broker-daemon Web UI branch behavior in `tests/unit/test_main.py`.
+2. Add failing tests for `BrokerProxy` spawn-arg propagation in `tests/unit/test_broker_proxy.py`.
+3. Add failing transport telemetry tests in `tests/unit/test_broker_transport.py`.
+4. Implement runtime changes after tests exist.
+5. Run required gates:
+   - `PYTHONPATH=src pytest`
+   - `ruff check src/`
+   - `mypy src/`
+   - `PYTHONPATH=src pytest --cov=src/mcpbridge_wrapper --cov-report=term-missing`
+
+## 4. Execution Plan (Hierarchical TODO)
+
+### Phase A — Broker+WebUI runtime orchestration
+- Inputs: `__main__.py` argument parsing and broker mode branches.
+- Outputs: broker-daemon mode can initialize Web UI components and start dashboard thread.
+- Verification: broker path exits through `asyncio.run(daemon.run_forever())` with Web UI active when requested.
+
+### Phase B — Broker telemetry integration
+- Inputs: `broker/transport.py` request/response routing logic.
+- Outputs: optional metrics/audit hooks recorded for `initialize` and `tools/call` traffic.
+- Verification: request latency/error stats emitted into shared store and audit stream.
+
+### Phase C — Auto-spawn configuration consistency
+- Inputs: `broker/proxy.py` spawn command construction.
+- Outputs: optional spawn args support so `--broker-spawn --web-ui` uses one shared config story.
+- Verification: spawned daemon command contains requested Web UI args.
+
+### Phase D — Validation/reporting
+- Inputs: updated code + tests.
+- Outputs: `SPECS/INPROGRESS/FU-P13-T17_Validation_Report.md` with PASS/FAIL and gate outputs.
+- Verification: acceptance criteria checklist fully resolved.
+
+## 5. Decision Points and Constraints
+
+- Keep Web UI hosting on broker daemon only; do not start dashboard in short-lived `--broker-connect` proxy processes.
+- Preserve current stdout protocol behavior: JSON-RPC only, no dashboard logs on stdout.
+- Keep feature additive and backward-compatible for existing configs.
+- Review subject name: `fu_p13_t17_broker_hosted_webui`.
+
+## 6. Notes (Files likely touched)
+
+- `src/mcpbridge_wrapper/__main__.py`
+- `src/mcpbridge_wrapper/broker/transport.py`
+- `src/mcpbridge_wrapper/broker/proxy.py`
+- `tests/unit/test_main.py`
+- `tests/unit/test_broker_proxy.py`
+- `tests/unit/test_broker_transport.py`

+# Validation Report: FU-P13-T17 — Enable broker-hosted Web UI with shared multi-client telemetry
+
+**Date:** 2026-02-28
+**Task ID:** FU-P13-T17
+**Verdict:** PASS
+
+## Scope Implemented
+
+- Updated `src/mcpbridge_wrapper/__main__.py` to support broker-hosted dashboard runtime:
+  - `--broker-daemon --web-ui` now starts broker transport and Web UI in one process.
+  - `--web-ui-only` is now rejected when combined with broker flags.
+  - Added shared helpers for Web UI runtime preparation and broker spawn arg construction.
+- Updated `src/mcpbridge_wrapper/broker/proxy.py`:
+  - Added configurable `spawn_args` support for `--broker-spawn` flows.
+  - Ensured daemon spawn command includes `--broker-daemon` plus propagated Web UI args.
+- Updated `src/mcpbridge_wrapper/broker/transport.py`:
+  - Added optional metrics/audit dependencies to broker transport.
+  - Added broker-side client identity capture (`initialize`) and tool telemetry tracking (`tools/call` request/response latency + error state).
+- Added/updated tests:
+  - `tests/unit/test_main.py`
+  - `tests/unit/test_broker_proxy.py`
+  - `tests/unit/test_broker_transport.py`
+
+## Quality Gates
+
+- `PYTHONPATH=src pytest` → PASS (`689 passed, 5 skipped, 2 warnings`)
+- `ruff check src/` → PASS
+- `mypy src/` → PASS
+- `PYTHONPATH=src pytest --cov=src/mcpbridge_wrapper --cov-report=term-missing` → PASS
+  - Total coverage: **91.81%** (required: >= 90%)
+
+## Acceptance Criteria Check
+
+- [x] `mcpbridge-wrapper --broker-daemon --web-ui --web-ui-config <path>` starts broker socket and dashboard without launching direct-mode bridge loop.
+- [x] `mcpbridge-wrapper --broker-spawn --web-ui --web-ui-config <path>` can auto-start a broker host with Web UI enabled.
+- [x] Tool calls from multiple broker-connected clients appear in one dashboard metrics/audit stream.
+- [x] Existing direct mode and broker-only behavior remain backward compatible.
+
+## Notes
+
+- In this environment, direct `pytest` (without `PYTHONPATH=src`) is not used for gating because imports resolve via `PYTHONPATH=src`.
