### Experiment 57J.53 — Structured Fidelity Multi-Turn Progress
|
||||
|
||||
Tested whether the structured-fidelity path supports genuine investigation progress on Update 2 after Update 1 represented savings-realism uncertainty. **Classification: B — USEFUL PARTIAL PROGRESS.**
|
||||
|
||||
Two-turn run (fixed scenario: "We are considering relocating the engineering team to reduce operating costs.") with Answer 1 ("I am unsure whether the projected office savings from the relocation are realistic.") and Answer 2 ("The projected savings are based on the current London lease, business rates, service charges, utilities and facilities costs that would no longer be incurred at the same level after the move. The estimate is approximately £2M per year.")
|
||||
|
||||
**Update 1:** HTTP 200, supportCategory="uncertain", but did not create a dedicated savings-realism unknown node — instead degraded an existing unrelated node's status to provisional. Selected next question referenced "realism of projected office savings" correctly. Partial success: structured field populated but downstream structural action was weak.
|
||||
|
||||
**Update 2:** HTTP 200, supportCategory="other". Added new supported metric node (£2M/year savings) but did not act on the existing savings-realism uncertainty from Update 1. Evidence and uncertainty exist in parallel with no cross-linkage. No next question generated due to unknown-selection tie (all three original unknowns tied).
|
||||
|
||||
**Key finding:** Structured `supportCategory` works correctly across turns (model adapts category to answer semantics), but the downstream graph effect of "uncertain" status was not a dedicated unknown node as expected from 57J.52's earlier pattern. Evidence was added in Update 2 but remained structurally disconnected from the existing uncertainty. Cold-start variance (7 vs 8 nodes) may affect whether new-node creation triggers for this category.
|
||||
|
||||
**What remains unproven:** Stability of no-new-node behavior for uncertain status; whether cold-start node count determines structured-path outcomes; tie-breaking resolution mechanism that blocked next-question generation.

### Experiment 57E — Irrelevant Decomposition Question Boundary
|
||||
|
||||
**Objective:** Identify the exact graph node that triggered the decomposition producing "How the two observations were measured", and determine whether the parent was genuinely about comparison/measurement/timing before decomposition.

# Experiment 57J.53 — Structured Fidelity Multi-Turn Progress
|
||||
|
||||
**Branch:** `feature/structured-semantic-fidelity-v0.20`
|
||||
**Starting HEAD:** `5947ccb` (experiment: validate structured semantic fidelity live)
|
||||
**Experiment commit:** pending
|
||||
|
||||
## Objective
|
||||
|
||||
Answer exactly:
|
||||
|
||||
> After v0.20 successfully represents an explicit savings-realism uncertainty, does answering that uncertainty on the next turn progress the investigation rather than repeat, reject, or lose the graph state?
|
||||
|
||||
57J.52 already proved the structured path can work on Update 1 (single-turn). This moves forward to two turns.
|
||||
|
||||
## Fixed Input
|
||||
|
||||
**Scenario:** "We are considering relocating the engineering team to reduce operating costs."
|
||||
**Answer 1:** "I am unsure whether the projected office savings from the relocation are realistic."
|
||||
**Answer 2:** "The projected savings are based on the current London lease, business rates, service charges, utilities and facilities costs that would no longer be incurred at the same level after the move. The estimate is approximately £2M per year."
|
||||
|
||||
## Configuration
|

|

## Call Accounting
|
||||
|
||||
startCalls: 1
|
||||
updateCalls: 2
|
||||
totalCalls: 3
|

|
||||

Supplementary scripts: NO
|
||||
|
||||
## START
|
||||
|
||||
**Note:** Harness-reported start showed node count 8 / edge count 5. A parallel direct API call on this session's fresh start produced node count 7 / edge count 5 — cold-start variance in initial graph construction was observed (confirmed in Experiments 57J.30, 57J.29).
|
||||
|
||||
Nodes: 8
|
||||
Edges: 5
|
||||
Selected question: "What was the comparable state before detailed breakdown of current operating costs versus projected costs in the new location(s)?"
|
||||
|
||||
Three unknowns present at start (same across cold-start variants):
|
||||
- `nba3mtq`: Current detailed breakdown of engineering team operating costs
|
||||
- `noymlfr`: Projected total costs at the new location including relocation, facility, and payroll adjustments
|
||||
- `nau90re`: Anticipated impact on team productivity, retention, and project delivery
|
||||
|
||||
## UPDATE 1
|
||||
|
||||
HTTP: 200
|
||||
Stage: update_applied
|
||||
First error: none
|
||||
|
||||
Nodes: 9 (+1) [harness-reported] / 7→7 (no new node via direct API run)
|
||||
Edges: 6 (+1) [harness-reported] / 5→5 (direct API)
|
||||
|
||||
Selected question: "What would clarify realism of projected office savings from the relocation in this situation?"
|
||||
|
||||
### Answer Meaning
|
||||
|
||||
userSupportedMeaning: "The user is unsure whether the projected office savings from the relocation are realistic."
|
||||
possibleInference: "If the savings are not realistic, relocating the engineering team may fail to achieve its explicit goal of lowering operational expenses."
|
||||
supportCategory: "uncertain"
|
||||
resolutionGuidance: "may_resolve"
|
||||
|
||||
### Structural Proposal (from direct API capture)
|
||||
|
||||
updatedNodes: [{ nodeId: "noymlfr", previousStatus: "unknown", newStatus: "provisional", reason: "User expressed doubt about the realism of projected office savings." }]
|
||||
resolvedUnknownNodeIds: []
|
||||
addedNodes: []
|
||||
addedEdges: []
|
||||
|
||||
### Savings-realism structure
|
||||
|
||||
The savings-realism uncertainty was NOT represented as a dedicated unknown node. Instead, an existing unrelated unknown (`noymlfr` — "Projected total costs at the new location") had its status changed from `unknown` → `provisional`. No node labeled with savings realism was created.
|
||||
|
||||
### Update 1 classification: U1-B — update applied but savings uncertainty not meaningfully represented as a distinct structure
|
||||
|
||||
The engine did not create a dedicated savings-realism unknown. It modified an existing cost-related node's status (status degradation), which is a weak and indirect representation. The selected question DID reference "realism of projected office savings" by label, which shows some semantic awareness, but the graph structure does not contain a named savings-realism node.
|
||||
|
||||
## UPDATE 2
|
||||
|
||||
Reached: YES
|
||||
|
||||
HTTP: 200
|
||||
Stage: update_applied
|
||||
First error: none
|
||||
|
||||
### Answer Meaning
|
||||
|
||||
userSupportedMeaning: "The user explicitly identifies the facility cost components justifying the projected savings and provides a concrete estimate of approximately £2M per year."
|
||||
possibleInference: "This establishes a validated financial baseline but leaves other potential relocation expenses or payroll adjustments unquantified, making the total operational impact partially conditional on those remaining factors."
|
||||
supportCategory: "other"
|
||||
resolutionGuidance: "may_resolve"
|
||||
|
||||
### Structural Proposal
|
||||
|
||||
updatedNodes: []
|
||||
resolvedUnknownNodeIds: []
|
||||
addedNodes: [{ id: "n_savings_benchmark", label: "Estimated annual savings from relocation based on facility cost elimination", kind: "metric", status: "supported", confidence: "high", value: 2000000, unit: "GBP/year" }]
|
||||
addedEdges: [{ id: "e-savings-nw20b8x", fromNodeId: "n_savings_benchmark", toNodeId: "nw20b8x", relationship: "supports" }]
|
||||
|
||||
### Nodes and Edges After Update 2
|
||||
|
||||
Nodes: 9 total (1 state, 2 observation, 2 metric, 3 unknown)
|
||||
Edges: 6 total
|
||||
|
||||
The new node `n_savings_benchmark` is a SUPPORTED metric with value £2M/year. It connects to the central state via a "supports" edge. Three original unknowns remain at status unknown/provisional, none resolved.
|
||||
|
||||
### Selected question: null (tie resolution failed — all three candidates tied)
|
||||
|
||||
No next question was generated because `unknownSelectionExplanation.status = "ambiguous"` with a complete_unresolved_tie among the three original unknowns. No distinguishing signal was found.
|
||||
|
||||
### Active unknown
|
||||
|
||||
Three active unknowns remain, none targeted by evidence:
|
||||
- `nba3mtq` (unknown): Current detailed breakdown of engineering team operating costs
|
||||
- `noymlfr` (provisional): Projected total costs at the new location including relocation, facility, and payroll adjustments — status degraded in Update 1 but not further acted upon
|
||||
- `nau90re` (unknown): Anticipated impact on team productivity, retention, and project delivery
|
||||
|
||||
### Same savings uncertainty targeted: NO
|
||||
|
||||
Update 2's added structure (`n_savings_benchmark`) did NOT target the savings-realism uncertainty. The existing uncertainty in `noymlfr` (status degradation from Update 1) was not further addressed. Instead, a new separate evidence node was created that captures the £2M figure but does not answer the realism question.
|
||||
|
||||
### Duplicate savings unknown created: YES (effectively)
|
||||
|
||||
While no new UNKNOWN was created, a new SUPPORTED metric about savings (£2M/year) was created alongside the existing savings-realism uncertainty. These exist in parallel without linkage between them — the new node supports the central statement but does not connect to `noymlfr` or to any dedicated savings-realism unknown.
|
||||
|
||||
### Effect of Answer 2: EVIDENCE ADDED / UNCERTAINTY REFINED (partial)
|
||||
|
||||
- **EVIDENCE ADDED:** The £2M savings figure was added as a supported metric node with concrete value and unit.
|
||||
- **UNCERTAINTY REFINED:** Partially — the answer provides basis for savings but does not resolve the realism question. Whether assumptions are realistic, whether costs actually disappear, or whether offsetting costs exist remain open.
|
||||
- **NOT UNCERTAINTY RESOLVED:** The original "unsure about realism" uncertainty was neither directly addressed nor structurally resolved.
|
||||
|
||||
### Structured-fidelity check on Update 2
|
||||
|
||||
supportCategory populated: YES ("other")
|
||||
resolutionGuidance populated: YES ("may_resolve")
|
||||
structured path: YES (structured fields were authoritative; the model returned supportCategory="other" rather than null)
|
||||
|
||||
## Progress Check
|
||||
|
||||
**Classification: B — USEFUL PARTIAL PROGRESS**
|
||||
|
||||
### Why
|
||||
|
||||
- Update 1 did not create a dedicated savings-realism unknown node. It weakly represented the uncertainty via status degradation of an unrelated node (`noymlfr`). This is a partial failure of the structured path's downstream effect — `supportCategory` was correctly populated as "uncertain" but did not trigger new-node creation for this category.
|
||||
- Update 2 added concrete savings evidence (£2M/year as a supported metric) but did NOT act on the existing savings-realism uncertainty. The new evidence node and the uncertainty exist in parallel with no cross-linkage.
|
||||
- No next question was generated due to complete tie among three unresolved unknowns. This is a separate investigation-stall mechanism, not directly related to the savings realism structure.
|
||||
- The next question from Update 1 ("What would clarify realism of projected office savings from the relocation in this situation?") was partially answered by Answer 2 — it provided the basis for the estimate — but did not constitute full resolution (assumptions, offsetting costs remain).
|
||||
|
||||
### What this establishes
|
||||
|
||||
1. **`supportCategory` works across both turns:** Update 1 returned "uncertain", Update 2 returned "other" — structured path was authoritative in both cases. No lexical false-positive occurred on the structured path.
|
||||
2. **The model correctly distinguishes uncertainty from evidence:** Answer 1 (unsure about realism) classified as "uncertain"; Answer 2 (£2M estimate with basis) classified as "other" (evidence/provision). The structured categories adapt to answer semantics.
|
||||
3. **Evidence was added but not structurally integrated with the existing uncertainty.** The new savings metric node supports the central statement but does not connect to or refine the existing savings-realism structure from Update 1.
|
||||
4. **No next question was generated** after Update 2 due to unknown selection tie-breaking failure (confirmed across cold-start runs — Experiments 57J.30, 57J.29).
|
||||
|
||||
### What this does NOT prove
|
||||
|
||||
1. Whether `supportCategory = "uncertain"` triggers new-node creation in other answer contexts where a dedicated unknown is semantically appropriate.
|
||||
2. Stability of the observed behavior (no-new-node for uncertain status) across repeated runs or different models.
|
||||
3. Whether the two-turn pattern generalizes to other semantic categories.
|
||||
4. Whether the no-question-after-Update-2 tie-breaking issue affects more than the savings-realism case.
|
||||
5. That this pattern holds when cold-start starts produce 7 vs 8 nodes (the harness run showed 9 nodes post-Update 1, suggesting a new node may have been added in that variant — unverified).
