This remediation is written to +> `plan-remediation.md` to avoid clobbering that record. + +## Context + +`/trekreview` returned **BLOCK**: the slice's three load-bearing seams — the +debate→validator dataflow, the `ChatMiddleware` token-budget enforcement, and the +MCP/retrieval tool path — are each built and unit-tested in isolation but are **never +connected by the orchestrator** (`run.py`). The e2e suite is green because it tests the +pieces against stand-ins and asserts proposal *shape* only. This plan wires the seams +together so the brief's core contract — "candidate measures debated → a deterministic +validator decides the value → enforced via a shared `ChatMiddleware` token budget, +provenance-stamped" (brief Goal + NFR) — is actually delivered, not decorative. + +The danger the review surfaced is that the green suite *masks* the defect. So a hard +constraint on this remediation: **the tests must exercise the real mechanism, not a +stand-in.** The single most important discovery during planning is that the existing +test double (`SyntheticUsageChatClient`) extends the **minimal `BaseChatClient`**, which +has **no `ChatMiddlewareLayer`** — so attaching the budget middleware to the debate +agents would silently no-op in every test, reproducing the exact "green tests, dead +mechanism" failure the review caught. The remediation therefore fixes the test double +(Step 1) before wiring the mechanism (Steps 2–4), and proves the mechanism fires on a +real layered client (Step 5). + +## Architecture Diagram + +```mermaid +graph TD + subgraph "run_project orchestrator (run.py) — the seams this plan connects" + meter["TokenMeter(Budget)"] + mw["BudgetMiddleware(meter) (NEW wiring)"] + tool["make_retrieval_tool(docs_dir) (NEW wiring)"] + fw["fresh_workflow(factory, tools=[tool], middleware=[mw])"] + debate["debate = GroupChat (proposer/checker)"] + run["result = await debate.run(...) → get_outputs() (NEW: captured)"] + gen["generate_via_llm(proposer, debate_output+context, meter)"] + val["validate_proposal → ValidatedProposal | Rejection"] + stamp["ProvenanceStamp(token_usage=meter.tokens)"] + + meter --> mw + mw --> fw + tool --> fw + fw --> debate + debate --> run + run -->|debate_output| gen + gen --> val + val --> stamp + end + subgraph "MAF 1.9.0 (installed-source-verified)" + layer["Agent(client, tools=, middleware=) — middleware fires only if client has ChatMiddlewareLayer"] + mw -.attaches via.-> layer + tool -.attaches via.-> layer + end +``` + +## Codebase Analysis + +- **Tech stack:** Python ≥3.10, `uv`, `ruff`, `mypy`, `pytest` (asyncio_mode=auto), + Pydantic 2.x.

Construct via `super().__init__(model="synthetic", api_key="synthetic", base_url="http://127.0.0.1:9/v1")` (offline — verified no network call until a request is actually sent). Keep the existing behavior verbatim: scripted/default replies, `call_count`, the **`tokens_per_reply` constructor kwarg name (unchanged)**, and a synthetic `UsageDetails(total_token_count=tokens_per_reply)` returned from the `_inner_get_response(*, messages, stream, options, **kwargs)` override (verified to be the slot the layered client calls for the raw response — it intercepts offline). Preserve the `make_client_factory`, `fresh_store`, `seeded_store`, `docs_dir` fixtures unchanged. No production code changes in this step. +- **Reuses:** existing `SyntheticUsageChatClient` body (`tests/conftest.py:26-73`); `OpenAIChatCompletionClient` construction pattern from `src/portfolio_optimiser/backends.py:89-94`. +- **Test first:** + - File: `tests/conftest.py` is test infra; the regression gate is the existing suite. + - Verifies: the re-based double is a drop-in — every existing test still passes (the double still emits synthetic `UsageDetails`, so strict-usage accounting does not hard-fail and `token_usage > 0` still holds). `conftest.py` is shared by the whole suite, so the gate MUST be the full suite, not a subset. + - Pattern: `tests/conftest.py:26-73` (current double). +- **Verify:** `uv run pytest -q` → expected: `97 passed, 3 skipped` (unchanged from pre-remediation — this proves the re-base is a true drop-in across every fixture consumer). +- **On failure:** retry once adjusting the `_inner_get_response` override signature to match the layered client's call contract; if the layered base demands network on construction, escalate (it does not — verified offline).

In `maker_checker_agents`, pass them to each agent: `Agent(client_factory(role), _INSTRUCTIONS[role], name=role, tools=tools, middleware=middleware)`. `fresh_workflow` forwards both to `maker_checker_agents`. **Also set `output_from=[agents[0]]` (the proposer) on the `GroupChatBuilder`** — this is a verified prerequisite for F1: empirically, `get_outputs()` by default surfaces ONLY the orchestrator's "reached max rounds" notice; `output_from=[proposer]` is what surfaces the proposer's converged text (Step 4 consumes it). Defaults `None` preserve current behavior. Update the module docstring line that claims the budget middleware is "wired by the orchestrator" to point at the new param. (Verified: `Agent.__init__` accepts both `tools=`/`middleware=`; `ChatMiddleware ∈ MiddlewareTypes`; `GroupChatBuilder(output_from=[proposer])` surfaces the proposer output.) +- **Reuses:** `maker_checker_agents` / `fresh_workflow` (`workflow.py:45-86`); `Agent` signature + `GroupChatBuilder(output_from=)` (introspected). +- **Test first:** + - File: `tests/test_workflow.py` (existing — add) + - Verifies: TWO assertions. (a) Construction-spy: monkeypatch `portfolio_optimiser.workflow.Agent` with a recorder, call `maker_checker_agents(factory, tools=[sentinel_tool], middleware=[sentinel_mw])`, assert every recorded construction received `tools` containing `sentinel_tool` and `middleware` containing `sentinel_mw` (`.tools` is not a public attr on a built `Agent`, so assert at the construction boundary). (b) Behavioral: run a real `fresh_workflow(scripted_factory).run(...)` where the proposer's FakeChatClient reply is a distinctive marker, and assert that marker appears in `[getattr(o,"text","") for o in result.get_outputs()]` — proving `output_from=[proposer]` actually surfaces the proposer's output (not just the orchestrator notice). + - Pattern: `tests/test_workflow.py:14-40` (factory style + `monkeypatch.setattr`). +- **Verify:** `uv run pytest tests/test_workflow.py -q` → expected: `all passed` +- **On failure:** revert — `git checkout -- src/portfolio_optimiser/workflow.py tests/test_workflow.py` +- **Checkpoint:** `git commit -m "feat(fase2): thread tools + budget middleware through fresh_workflow onto agents"` +- **Manifest:** + ```yaml + manifest: + expected_paths: + - src/portfolio_optimiser/workflow.py + - tests/test_workflow.py + min_file_count: 2 + commit_message_pattern: "^feat\\(fase2\\): thread tools \\+ budget middleware through fresh_workflow onto agents$" + bash_syntax_check: [] + forbidden_paths: + - src/portfolio_optimiser/budget.py + must_contain: + - path: src/portfolio_optimiser/workflow.py + pattern: "middleware=middleware" + - path: src/portfolio_optimiser/workflow.py + pattern: "tools=tools" + - path: src/portfolio_optimiser/workflow.py + pattern: "output_from" + ``` + +### Step 3: Construct and attach BudgetMiddleware + retrieval tool in the orchestrator + +- **Files:** `src/portfolio_optimiser/run.py`, `tests/test_vertical_slice_e2e.py` +- **Changes:** In `run_project`, after building `meter` (`run.py:121`), construct `mw = BudgetMiddleware(meter)` and `retrieval_tool = make_retrieval_tool(docs_dir, top_k=top_k)`, then pass both into the factory call: `debate = fresh_workflow(factory, max_rounds=max_rounds, enable_layer1_hitl=enable_layer1_hitl, tools=[retrieval_tool], middleware=[mw])`. Add the imports `from portfolio_optimiser.budget import Budget, TokenMeter, BudgetMiddleware` and `from portfolio_optimiser.datasource import ..., make_retrieval_tool`. This makes the debate's per-call token usage flow through the shared meter via the `ChatMiddleware` (the brief's named mechanism) and gives the agents the citation-bearing data-source tool.

Add a helper `_debate_text(result) -> str` with the **verified** extraction: iterate `result.get_outputs()`, read each element's `.text`, **exclude the orchestrator's termination notice** (an element whose `author_name == "group_chat_orchestrator"`, or whose text contains `"reached the maximum number of rounds"`), and return the last remaining non-empty text (the proposer's converged output surfaced by `output_from=[proposer]` from Step 2); return `""` if none. Build the generation context from BOTH the debate output and the citations: `gen_context = _debate_text(result) or context` — passed to `generate_via_llm(factory("proposer"), project, gen_context, meter)`, so the validated proposal provably derives from the debate (retrieval `context` only as a last-resort fallback; note: the fallback path is a *test failure* per `test_g`, not a silent degradation — the test asserts the debate marker reaches generation). Add `debate_output: str` to `RunResult` and populate it (the minimal observable surface F1's mandated assertion needs). **F9 (MINOR, the `fake-model` provenance label) is OUT OF SCOPE for this remediation** — it is advisory only (Handover 6 excludes MINOR); deferred as an optional follow-on, NOT addressed here, to keep this step focused on the BLOCKER. +- **Reuses:** `generate_via_llm` (`generate.py:92`), `WorkflowRunResult.get_outputs()` returning `AgentResponse` with `.text` (verified), `RunResult` dataclass (`run.py:52`). +- **Test first:** + - File: `tests/test_vertical_slice_e2e.py` (existing — add) + - Verifies: `test_g_validated_proposal_derives_from_debate` — a spy captures the `context` argument passed to `generate_via_llm` (monkeypatch `portfolio_optimiser.run.generate_via_llm`), scripts the debate agents (via the proposer's FakeChatClient/synthetic reply) to emit a distinctive marker string, runs `run_project`, and asserts (a) `result.debate_output` is non-empty and contains the scripted marker, and (b) the captured generation context contains that marker — i.e. deleting the debate would change the generation input (the precise gap the review named).

In `tests/test_budget.py`, add `test_budget_middleware_fires_on_real_agent_chat`: build an `Agent(SyntheticUsageChatClient(tokens_per_reply=8), "x", name="proposer", middleware=[BudgetMiddleware(TokenMeter(Budget(max_tokens=5, max_rounds=10)))])`, `await agent.run("hi")`, assert `BudgetExceeded` is raised from the middleware path with `kind == "tokens"` (verified empirically: meter charged to 8 > cap 5). In `tests/test_vertical_slice_e2e.py`, add `test_h_tiny_budget_halts_via_debate_middleware` — and make it genuinely load-bearing (the critic's catch): **monkeypatch `portfolio_optimiser.run.generate_via_llm` to raise `AssertionError` if it is ever called**, then run `run_project` with a tiny `max_tokens` and per-reply tokens above it, asserting `BudgetExceeded` is raised. Because `generate_via_llm` independently raises `BudgetExceeded` (`generate.py:111`), a plain `pytest.raises` would pass even if the debate middleware no-ops (the exact "green-but-dead" trap) — failing the test the moment generation is reached forces the `BudgetExceeded` to originate in the **debate** `ChatMiddleware` (verified it propagates out of `debate.run()`), so detaching the debate middleware fails this test. Keep the existing `test_e` as-is (still green; its mechanism shifts from the generate loop to the debate middleware — note this in its docstring). +- **Reuses:** `BudgetMiddleware` (`budget.py:81`), the re-based `SyntheticUsageChatClient` (Step 1), `run_project` wiring (Steps 2-4). +- **Test first:** + - File: `tests/test_budget.py` (existing — add) and `tests/test_vertical_slice_e2e.py` (existing — add) + - Verifies: detaching `BudgetMiddleware` from the agent now fails a test (the middleware↔real-client integration is no longer untested — the exact gap from F8). + - Pattern: `tests/test_budget.py:41-56` (middleware assertion) + `tests/test_vertical_slice_e2e.py:74-82` (tiny-budget e2e). +- **Verify:** `uv run pytest tests/test_budget.py tests/test_vertical_slice_e2e.py -q` → expected: `all passed` +- **On failure:** revert — `git checkout -- tests/test_budget.py tests/test_vertical_slice_e2e.py` +- **Checkpoint:** `git commit -m "test(fase2): assert BudgetMiddleware short-circuits a real chat call + the debate"` +- **Manifest:** + ```yaml + manifest: + expected_paths: + - tests/test_budget.py + - tests/test_vertical_slice_e2e.py + min_file_count: 2 + commit_message_pattern: "^test\\(fase2\\): assert BudgetMiddleware short-circuits a real chat call \\+ the debate$" + bash_syntax_check: [] + forbidden_paths: + - src/portfolio_optimiser/budget.py + must_contain: + - path: tests/test_budget.py + pattern: "agent.run" + ``` + +### Step 6: Commit the env contract artifact under a pathguard-permitted name + +- **Files:** `env.template` (new) +- **Changes:** Create `env.template` at the repo root with the staged content documenting `PORTFOLIO_LOCAL_BASE_URL` / `PORTFOLIO_LOCAL_API_KEY`, the Foundry `PORTFOLIO_FOUNDRY_PROJECT_ENDPOINT`, and the research-03 no-egress notes (loopback only, Ollama bind `127.0.0.1`, pin ≥ 0.17.1, `OLLAMA_DEBUG` unset, model-pull = explicit egress).
