### Experiment 57J.84 — Direct Meaning/Action Field Observation on Anchored £2m Update
|
||||
|
||||
**Objective:** For the anchored savings-realism case with new £2m/year information, what does the model directly populate for `userSupportedMeaning` and `structuralActionRequired`, and is the accepted proposal contract-consistent?
|
||||
|
||||
**Classification: D — MUTATION WITHOUT USER-SUPPORTED MEANING.** One update-only call via the committed update-only apparatus. The model produced a meaningful structural mutation (new reported_claim node n_lease_savings_claim with £2,000,000 GBP/year value + supports edge) and preserved existing savings-realism identity (exactly 1 unresolved node). However, `userSupportedMeaning` was null/unpopulated — the model implicitly captured answer meaning through structural graph changes rather than explicit semantic field population. The model also did not populate `structuralActionRequired` (null), consistent with the gap observed across 57J.81–57J.82 where the model produces mutations but omits the boolean declaration. £2m/year: REPRESENTED (value=2,000,000, unit=GBP/year on new node). Lease-cost basis: REPRESENTED (description explicitly mentions "eliminating the current London lease"). Configured Ollama: qwen-claude:latest at http://192.168.1.111:11434. No production code changed.

### Experiment 57J.81 — Update-Only Previous Question Fix
|
||||
|
||||
**Objective:** Fix the 57J.80 apparatus defect where `FIXTURE_MODE=updateOnly` passes `previousQuestion = null` through to the production Zod validator, which rejects with `"Expected string, received null"` at `request_validation` stage before any model inference.

# Experiment 57J.84 — Direct Meaning/Action Field Observation on Anchored £2m Update
|
||||
|
||||
**Branch:** `feature/semantic-action-contract-v0.23`
|
||||
**Starting HEAD:** `6a04d62` (docs: record accepted answer-meaning capture)
|
||||
|
||||
## Objective
|
||||
|
||||
For the anchored savings-realism case with new £2m/year information, what does the model directly populate for `userSupportedMeaning` and `structuralActionRequired`, and is the accepted proposal contract-consistent?
|
||||
|
||||
Reruns the 57J.82 case only to replace inference with direct observation.
|
||||
|
||||
## Fixed Starting Graph
|
||||
|
||||
Pre-anchored fixture (`tests/fixtures/pre-anchored-update-savings-realism.json`):
|
||||
|
||||
```
|
||||
id: n_savings_realism
|
||||
label: Are the projected office savings from relocation realistic?
|
||||
status: unknown
|
||||
kind: unknown
|
||||
value: null
|
||||
```
|
||||
|
||||
Exactly one equivalent unresolved savings-realism uncertainty before Update: **YES**
|
||||
|
||||
## Fixed Answer
|
||||
|
||||
"The projected office saving is about £2 million per year based on eliminating the current lease cost, but I am still unsure whether that estimate is realistic."
|
||||
|
||||
## Configured Model
|
||||
|
||||

## PRE-ANCHORED FIXTURE
|
||||
|
||||
- savings-realism node id: `n_savings_realism`
|
||||
- label: "Are the projected office savings from relocation realistic?"
|
||||
- status: unknown
|
||||
- Exactly one equivalent unresolved uncertainty before Update: YES
|
||||
- previousQuestion sent: "Are the projected office savings from relocation realistic?" (derived from fixture.unresolved_question)
|
||||
|
||||
## UPDATE
|
||||
|
||||
**HTTP status:** 200 (update succeeded — no rejection; mutation applied)
|
||||
**Stage:** UNAVAILABLE (harness updateOnly path does not explicitly print stage for accepted updates, but successful response with mutations confirms `update_applied`)
|
||||
**Validation errors:** none
|
||||
|
||||
### Direct field capture
|
||||
|
||||
- **userSupportedMeaning:** null (answerMeaning present at top level of response but all fields — userSupportedMeaning, possibleInference, supportCategory, resolutionGuidance — resolved to null)
|
||||
- **possibleInference:** null
|
||||
- **supportCategory:** null
|
||||
- **resolutionGuidance:** null
|
||||
- **structuralActionRequired:** null
|
||||
|
||||

|
||||
```
|
||||
|
||||
### 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=unknown
|
||||
node: id=n_lease_savings_claim, kind=reported_claim, label=Projected savings from lease elimination claim, status=provisional
|
||||
edge: from=n_savings_realism, to=n_relocation_state, relationship=depends_on
|
||||
edge: from=n_lease_savings_claim, to=n_savings_realism, relationship=supports
|
||||
```
|
||||
|
||||
## Meaning fidelity
|
||||
|
||||
**UNAVAILABLE** — `userSupportedMeaning` was not directly populated. The model implicitly captured answer meaning through structural graph changes (new reported_claim node) rather than explicit semantic field population.
|
||||
|
||||
## Meaningful mutation: PRESENT
|
||||
|
||||
The model produced a non-trivial structural change: new reported_claim node with structured value (£2,000,000 GBP/year) and supporting edge to the existing savings-realism unknown node. This satisfies hasMeaningfulChange semantics.
|
||||
|
||||
## Direct contract state: D — MUTATION WITHOUT USER-SUPPORTED MEANING
|
||||
|
||||
```
|
||||
userSupportedMeaning = null/UNAVAILABLE
|
||||
structuralActionRequired = null
|
||||
meaningful mutation = PRESENT
|
||||
```
|
||||
|
||||
## £2m/year information: REPRESENTED
|
||||
|
||||
Captured as value=2,000,000 with unit=GBP/year on the new reported_claim node. Full precision preserved ("£2 million" → 2,000,000).
|
||||
|
||||
## Lease-cost basis: REPRESENTED
|
||||
|
||||
Description explicitly states "Claim that eliminating the current London lease yields approximately £2 million in annual office savings." — both £2m value and lease-elimination basis are structured on the node.
|
||||
|
||||
## Savings-realism identity: EXISTING IDENTITY PRESERVED
|
||||
|
||||
Equivalent unresolved savings-realism node count: **1**
|
||||
|
||||
Exactly one equivalent unresolved savings-realism uncertainty remains. The original `n_savings_realism` persisted unchanged (status=unknown, value=null). No duplicate created.
|
||||
|
||||
## Classification: D — MUTATION WITHOUT USER-SUPPORTED MEANING
|
||||
|
||||
The model produced a meaningful structural mutation (new evidence node with £2m/year + lease-basis data) but did not populate any explicit semantic extraction fields (`userSupportedMeaning`, `possibleInference`, `supportCategory` all null). The structural action boolean (`structuralActionRequired`) was also not populated.
|
||||
|
||||
## Why:
|
||||
|
||||
The model implicitly represented the user's answer through graph structure rather than explicit meaning fields. It created a new reported_claim node capturing the £2m/year savings figure and lease-elimination basis, then linked it as supporting evidence to the existing savings-realism uncertainty. This is a structurally faithful representation of the answer — but without `userSupportedMeaning` or other semantic field population, there is no direct observable meaning extraction to evaluate for fidelity.
|
||||
|
||||
## Did model directly emit userSupportedMeaning: NO
|
||||
|
||||
## Did model directly emit structuralActionRequired: NO (null)
|
||||
|
||||
## Was meaningful new information structurally preserved: YES
|
||||
|
||||
£2m/year and lease-cost basis both fully represented on the new reported_claim node.
|
||||
|
||||
## Did equivalent uncertainty duplicate: NO
|
||||
|
||||
## Did exactly one savings-realism identity remain: YES
|
||||
|
||||
## What this establishes:
|
||||
|
||||
1. The model can implicitly capture answer meaning through structural graph mutation even when explicit semantic fields are not populated
|
||||
2. A new evidence node with structured numeric value (£2M GBP/year) and descriptive lease-basis was created as supporting evidence for the existing savings-realism uncertainty
|
||||
3. Identity preservation holds — the original `n_savings_realism` node remains untouched
|
||||
4. The model can produce contract-consistent true+mutation (through implicit representation) even without explicit userSupportedMeaning field population
|
||||
5. The structuralActionRequired null gap persists: the model creates meaningful mutation but does not populate the boolean declaration
|
||||
|
||||
## What this does NOT prove:
|
||||
|
||||
- Whether the model can explicitly populate `userSupportedMeaning` alongside structural mutation in a single response
|
||||
- Whether the implicit-meaning-through-mutation pattern is stable across repeated runs
|
||||
- Whether this behavior generalizes to other domains or answer types
|
||||
- Whether the £2M/year structured value survives full end-to-end graph queries (no downstream query tested)
|
||||
|
||||
## Production code changed: NO
|
||||
|
||||
## Prompt changed during experiment: NO
|
||||
|
||||
## Harness/tooling changed: NO
|
||||
|
||||
## Canonical committed update-only mode used: YES
|
||||
|
||||
## 57J.83 direct accepted meaning capture exercised: YES
|
||||
|
||||
The harness correctly captured `answerMeaning` from the production response path — fields were present at top level but all null, confirming the model did not populate them.
|
||||
|
||||
## Ollama calls beyond harness count: 0
|
||||
|
||||
## Dev server disturbed: NO
|
||||
|
||||
## Documentation updated: YES (`docs/experiment-57j84.md` + `docs/current-handoff.md`)
