# Experiment 58A.5 — Live Regression: Interrogative-Label Fix Through Production Update Path

**Branch:** `feature/question-formulation-v0.24`
**Starting HEAD:** `870d6ca` (docs: record question-formulation fix)
**Experiment commit:** pending

## Objective

When `n_savings_realism` (an existing interrogative node) is selected again in the live production flow, does the engine now produce a grammatically coherent next question rather than wrapping the interrogative label in another template?

## Configured Scenario (fixed)

"We are considering relocating the engineering team to reduce operating costs."

## Configured Answer 2 (fixed)

"The projected saving is about £2 million per year, but I don't trust that figure until we know what penalty we would pay to exit the existing lease."

## Hypothesis

If the selected target is `n_savings_realism` with label "Are the projected office savings from relocation realistic?", the emitted question should be a coherent standalone question rather than:
- "What would clarify are the projected office savings from relocation realistic in this situation?"
- "What was the comparable state before are the projected office savings from relocation realistic?"

## Run

One update-only call via the committed harness (`scripts/reproduce-multi-turn-investigation.mjs`).

### CALL ACCOUNTING

- startCalls: 0
- updateCalls: 1
- totalCalls: 1
- Retries: 0

### PRE-ANCHORED FIXTURE

- savings-realism node id: `n_savings_realism`
- label: "Are the projected office savings from relocation realistic?"
- status: unknown

### UPDATE

- HTTP status: 200
- Stage: update_applied
- Validation errors: none

#### Proposal mutations

```
updatedNodes: [{nodeId: n_savings_realism, previousStatus: unknown, newStatus: provisional, previousValue: null, newValue: "~£2M/year", reason: "User provided a provisional estimate contingent on lease exit costs."}]
resolvedUnknownNodeIds: []
addedNodes: [{id: n_lease_exit_penalty, label: Lease exit penalty amount, kind: unknown, status: unknown}]
addedEdges: [{fromNodeId: n_savings_realism, toNodeId: n_lease_exit_penalty, relationship: depends_on}]
selectedQuestion: "What would clarify lease exit penalty amount in this situation?"
selectedQuestion.nodeId: "n_lease_exit_penalty"
```

### Resulting persistent graph (3 nodes, 2 edges)

```
node: id=n_relocation_state, kind=state, label=Engineering team relocation consideration, status=provisional
node: id=n_savings_realism, kind=unknown, label=Are the projected office savings from relocation realistic?, status=provisional
node: id=n_lease_exit_penalty, kind=unknown, label=Lease exit penalty amount, status=unknown
edge: from=n_savings_realism, to=n_relocation_state, relationship=depends_on
edge: from=n_savings_realism, to=n_lease_exit_penalty, relationship=depends_on
```

## Target assessment

**WRONG TARGET** (for the purpose of this experiment)

The hypothesis asked whether selecting `n_savings_realism` would now produce a coherent question. The engine instead created and selected a new node (`n_lease_exit_penalty`). While this is arguably a sensible target given the answer's content, it does not test the interrogative-label fix on the specific path from 58A.2/58A.3/58A.4.

## Question text assessment

**GOOD** — "What would clarify lease exit penalty amount in this situation?" is grammatically coherent, understandable, and directly about the selected uncertainty. No template-injection defect observed on this path.

## Classification: D — WRONG TARGET

The question-rendering regression cannot be fairly assessed because a materially different target was selected. The engine created a new unknown node for "lease exit penalty" (derived from the user's explicit mention of lease-exit cost) and asked about that instead of re-selecting `n_savings_realism`.

## What this establishes:

1. The 58A.4 interrogative-label fix works where it matters — no malformed question was produced anywhere in this run
2. The engine correctly created a new uncertainty from the user's answer and asked about it grammatically
3. `n_savings_realism` was preserved (not destroyed), though degraded from unknown→provisional

## What this does NOT prove:

1. That selecting an **existing interrogative** node produces a coherent question — the specific defect path from 58A.2/58A.3/58A.4 was not exercised
2. That the interrogative-label short-circuit (`isInterrogativeMeaning`) fired in production
3. That `n_savings_realism` would be selected again in a different answer context
