Read-only inspection of 8 files (prompt-builder.js, schema.js, utils.js,
apply-proposal.js, orchestrator.js, experiment-60b1.md, experiment-60b2.md,
current-handoff.md). No code changes.
Key findings:
- Prompt has no independent materiality/sufficiency rule (Rule 20 says null
selectedQuestion when 'no consequential unresolved unknown' but doesn't define
what makes an unknown non-consequential)
- Validator performs structural checks only, no evidence sufficiency evaluation
- No cross-option comparison logic in propagateResolvedChildEvidence
- Schema has no materiality or couldChangeDecision field
- 60B.1 resolved WITH 'no other material differences' cue; 60B.2 continued
WITHOUT it, despite internally computing ~3.6 month payback
Classification: C — NO SUFFICIENCY RULE + CONTINUATION BIAS
Missing distinction: MATERIALITY / DECISION-RELEVANCE RULE
Implementation of Candidate B (unknown+option) from decision architecture
design in 60A.2. Adds two new primitives to the situation graph:
Schema (lib/graph/schema.js):
- SituationKind.option — a choice available within a decision context
- SituationRelationship.contained_in — links option → its parent unknown context
Prompt rules (lib/graph/prompt-builder.js):
- Section added: Decision Option Structure Rules with 5 numbered instructions
governing when/how to create option nodes, link them via contained_in,
attach consequences to specific options, and handle do-nothing alternatives.
Explicitly forbids alternative_to edges and is_baseline/is_default flags.
Tests (446 new lines):
- schema.test.js: +300 — enum completeness updates, option kind validation,
contained_in edge validation, native two-option graph fixture (~25 new tests)
- prompt-builder.test.js: +133 — focused rules verification for all 5 rule points,
negative checks (no relocation/savings/example-specific wording, no alternative_to
requirement, baseline flag prohibition context)
No production code paths affected beyond the two enum additions; existing node and
edge kinds remain unchanged. No Ollama calls, no live API calls.
Diagnoses the root cause of the persistent pattern from 59B.2-59B.4
where explicit dual-option input collapsed into a single undifferentiated
unknown node. Concludes the graph vocabulary lacks first-class primitives
for options/decisions (not primarily a prompt issue). Identifies three
missing primitives: option node kind, decision node kind, alternative_of
edge type. Recommends ~25-line schema addition for 60A.2 implementation.
