The requirements synthesis for the next implementation pass lives in `docs/reasoning-refinement-requirements.md` — read it first. The key problem is preserving user-supported meaning, model inference, qualification, and unresolved uncertainty distinctly enough that later reasoning cannot silently convert one into another. Tomorrow should begin with code inspection against the requirements and regression pack rather than more semantic exploration. Production architecture is still undecided; no graph fields, Behaviour Selection changes, or UI layout have been prescribed. Branch: `feature/user-workspace-ux-v0.7`. This commit consolidates all findings into that single bounded document. +The first implementation pass against the reasoning refinement requirements is deferred one more round while we map how meaning actually flows through the production update path — before committing to any schema or architecture changes. A source-inspection exercise traced the full answer-to-reasoning chain from prompt building, through LLM response parsing and normalization, into graph mutation. The key finding: no provenance fields exist on nodes or edges in the current schema, meaning R1/R2 separation has no structural carrier. The answer string is used only for a narrow comparability check, not for semantic verification against proposed changes. A complete path map lives in `docs/reasoning-production-path-map.md`. Tomorrow should decide whether to add provenance fields to schemas, modify the prompt structure, or both — grounded in this accurate production trace rather than architectural speculation.

The production path does not carry semantic meaning — it carries structural graph changes that represent the LLM's interpretation of the answer.

How the Answer Enters the Prompt + +File: `lib/graph/prompt-builder.js`, function `buildGraphUpdatePrompt()` (lines 26–132). + +The prompt template includes four key sections: + +- `## Current Situation Graph` — the full graph serialized to JSON (line 43) +- `## Previous Selected Question` — text of the last question asked (line 46) +- `## User Answer` — the raw user answer as a plain text string (line 49) +- `## Proposal Rules` (lines 86–130) — constraints on what the model should produce in the JSON response + +**Important:** The answer appears only as free text within the prompt body. No provenance annotation, source ID, or semantic field is attached to it. It is indistinguishable from context text at the prompt level beyond section headers. + +**Requirement support status at this boundary:** +- R1 (preserve user-supplied meaning): Partially supported — the `## User Answer` section header and placement within a clearly bounded section help; however, there is no explicit instruction or structural constraint that prevents the model from strengthening or reinterpreting what was stated. +- R2 (keep inference distinguishable): Gap — the prompt does not instruct the model to separate user statement from interpretation in its output. The response schema has no fields for source vs inference tracking. +- R3–R8: Unsupported at this boundary — the prompt rules focus on graph topology constraints, not semantic fidelity of meaning preservation. + +--- + +## 3. What Happens After the LLM Response (Parsing and Normalization) + +File: `lib/graph/update-proposal.js`, function `parseGraphUpdateProposal()` (lines 100–157). + +This step performs four normalizations before validation: + +1. **JSON parsing** — attempts to parse the model's text response as JSON +2. **Null array entry removal** (`removeNullArrayEntries`) — filters null items from arrays +3. **Enum alias conversion** (`applyKnownEnumAliases`) — converts `reported_statement` → `reported_claim` on node kind values +4. **Missing field filling** (`fillMissingOptionalArrays`, `fillMissingNullableFields`) — fills absent array fields with `[]`, absent nullable fields with `null` + +Then the normalized proposal is validated against `graphUpdateSchema`. + +**Critical gap:** No provenance, source-tracking, or semantic-meaning fields exist anywhere on nodes, edges, or in the graph update schema. The parsed proposal contains only structural change operations (`addedNodes`, `updatedNodes`, `addedEdges`, etc.) with no annotation about which parts came from the user vs the model's inference. + +**Requirement support status at this boundary:** +- R1 (preserve user-supplied meaning): Gap — normalization transforms the LLM output but does not preserve or verify semantic content against the original answer. +- R2 (keep inference distinguishable): Gap — no provenance fields exist on nodes, edges, or in the update schema. The distinction between user-originated and model-inferred content is lost at parsing time. +- R3–R8: Unsupported at this boundary — normalization is purely structural; semantic preservation checks do not occur. + +--- + +## 4. Graph Mutation and Resolution (applyValidatedProposal) + +File: `lib/graph/apply-proposal.js`, function `applyValidatedProposal()` (lines 2719+). + +This is the largest and most complex step. It performs: + +1. **Graph validation** (situationGraphSchema + graphUpdateSchema) +2. **Resolution semantics reconciliation** (`reconcileResolutionSemantics`) — ensures nodes marked as resolved also have updated status +3. **Graph update compatibility validation** — edge references, node ID uniqueness, semantic duplicate unknown detection +4. **applyGraphUpdate** — actually mutates the graph with added/updated/removed nodes and edges +5. **Reasoning state derivation** (`deriveReasoningStateOverride`) — the only code that inspects the answer text directly; currently only handles comparability confirmation (lines 2685–2717) +6. **Observation relationship classification** (`classifyObservationRelationship`) +7. **Emergent reasoning unknown creation** (`buildEmergentReasoningUnknown`) +8. **Deterministic decomposition** (`runDeterministicDecomposition`) — quality checks on child unknowns, pattern compatibility, semantic similarity analysis +9. **Evidence propagation** (`propagateResolvedChildEvidence`) — up-chains status through parent-child relationships +10. **Question selection** (`selectActiveUnknownCandidate`, `determineGraphBackedQuestion`) + +**Key insight for reasoning requirements:** The answer string is passed to `deriveReasoningStateOverride` at line 2878 but is only used for a narrow comparability check (line 2698: `answerConfirmsComparability(answer)`). After that point, the original answer text no longer flows through the mutation path — only the structural graph state does. The model's LLM interpretation of the answer is already embedded in the proposed node/edge changes. + +**Requirement support status at this boundary:** +- R1 (preserve user-supplied meaning): Gap — the answer string reaches `deriveReasoningStateOverride` but is not compared against or verified with any proposed content. The graph mutation operates on structural changes, not semantic verification. +- R2 (keep inference distinguishable): Gap — by the time applyValidatedProposal runs, user-originated and model-inferred content are merged into a single graph state. No per-node source tracking exists. +- R3 (preserve qualification/conditionality): Gap — no mechanism compares the preserved qualification from the original answer against what appears in updated node values/statuses. +- R4 (preserve unresolved uncertainty): Partially supported — if the LLM correctly proposes `resolvedUnknownNodeIds` for only truly answered targets, uncertainty is preserved by omission. But there is no verification that uncertain parts of the answer were not implicitly resolved. +- R5 (distinguish evidence from clarification): Supported at the graph level — the schema already carries relationship types that distinguish evidence-supported vs user-clarification paths. +- R6 (clarify actual distinction): Unsupported — question formulation happens downstream and operates on graph structure, not on preserving a specific clarification target from the answer. +- R7 (avoid unnecessary clarification): Partially supported — `selectedQuestion` can be null; validation ensures no spurious unknowns are added. But there is no check against whether the original answer explicitly declined clarification. +- R8 (resolution on preserved meaning): Gap — resolution operates on graph state, not on a preserved-meaning field derived from the answer. If the LLM strengthened or lost meaning in its interpretation, that distorted interpretation becomes the basis for all downstream reasoning. + +--- + +## 5.

Where Meaning Preservation Must Enter (Gap Locations) + +Based on this trace, meaningful reasoning support at the production path requires changes at these specific locations: + +1. **Schema layer** (`lib/graph/schema.js`): `situationNodeSchema`, `graphUpdateSchema`, and potentially `updateCaseRequestSchema` need fields to carry meaning provenance. Currently no schema has any semantic-meaning fields. + +2. **Prompt layer** (`lib/graph/prompt-builder.js`): The prompt template would need explicit instruction and response format requirements that require the model to separate user-originated content from its own interpretation in the proposal output. + +3. **Parsing layer** (`lib/graph/update-proposal.js`): After JSON parsing but before schema validation, semantic-meaning fields would need to be extracted and verified against the original answer text. + +4. **Application layer** (`lib/graph/apply-proposal.js`): After `deriveReasoningStateOverride` at line 2875, a comparison step could verify that proposed graph changes do not contradict or strengthen the original answer meaning. + +--- + +## 8. Current-State Assessment for Each Requirement + +### R1: Preserve user-supplied meaning +**Status:** Gap — No mechanism exists to preserve or verify semantic content against the original answer. The answer flows through the prompt once and then is effectively discarded after parsing, with only its LLM interpretation surviving in graph state. + +### R2: Keep inference distinguishable +**Status:** Gap — The output schema has no provenance fields on nodes or edges. Even if a future mechanism separated user vs inference content in the model's response, there is no schema path for that data to flow through the mutation cycle. + +### R3: Preserve qualification and conditionality +**Status:** Gap — No mechanism compares preserved qualification from the answer against proposed node values. The `reason` field on `updatedNodes` is free-text and not verified against the original answer. + +### R4: Preserve unresolved uncertainty +**Status:** Partially supported by existing gates, but verification is LLM-dependent only. The schema supports null/unknown statuses, but there is no mechanism to verify that uncertainty stated in the answer was not silently resolved. + +### R5: Distinguish evidence need from clarification need +**Status:** Supported — existing relationship types and node kinds provide structural distinction between evidence-supported items and user-clarification needs. + +### R6: Clarify the actual unresolved distinction +**Status:** Partially supported — question selection has quality gates (decomposition, atomicity) but no mechanism to preserve a specific clarification target from the answer text. + +### R7: Avoid unnecessary clarification +**Status:** Partially supported by structural constraints — empty arrays and null selectedQuestion are valid. No explicit mechanism to enforce that the original answer's intent not to clarify was respected. + +### R8: Resolution on preserved meaning +**Status:** Gap — Resolution operates entirely on graph state, which reflects the LLM's interpretation of the answer rather than any explicitly preserved meaning from the user's words. + +--- + +## 9. Current-State Assessment for Known Good Behaviours and Failure Modes + +### Known good behaviours (currently working) +These work because they are enforced by existing structural gates, not semantic verification: + +- **Explicit hard constraint remains hard constraint** — Works because the LLM follows prompt rules about not downgrading explicit statements (instruction-based, not verified). +- **"I'm not really sure" stays uncertain** — Works because there is no structural mechanism to force resolution without explicit resolvedUnknownNodeIds in the proposal. +- **Operational disagreement is evidence-resolvable** — Works because relationship types allow distinguishing evidence from clarification needs. +- **Deterministic source identity via SHA-256** — This was demonstrated experimentally (54H) but is not integrated into any production schema or code path. + +### Known failure modes (current gap exposure) +These fail because there is no semantic verification between the answer and the proposed graph changes: + +- **Weak priority over-resolved to "not a constraint"** — The LLM strengthens relative importance; no mechanism prevents this because there is no comparison against original meaning. +- **Conditional trade-off losing qualification** — Same root cause — structural updates carry the interpretation, not the preserved qualification. +- **Target broadening replacing material distinction** — The question formulation step operates on graph structure and can lose precision that existed in the original answer text. +- **Stage 1 distortion propagating through Stage 2** — Since the answer meaning is never preserved as a separate artifact, all downstream reasoning works on interpretation rather than source. + +--- + +## 10.
