feat(infospace): add L2 entity classification with type × VSM matrix (S2.9)
Implements the L2 typed-entities layer — each entity is assigned an
Entity Type (Element, Process, Relation, Principle, Institution) and a
VSM System (S1–S5) by an LLM, with one-sentence rationales for each.
New modules:
- markitect/infospace/classification.py — EntityClassification dataclass
+ ENTITY_TYPES / VSM_SYSTEMS controlled vocabularies
- markitect/infospace/classification_io.py — write/read classification
files (YAML frontmatter + markdown body, mirrors evaluation_io)
- markitect/infospace/classifier.py — build_classification_prompt(),
parse_classification_response(), run_entity_classification(); batch
runner writes files incrementally (same resumable pattern as evaluate)
CLI: markitect infospace classify [--entity SLUG] [--provider P] [--model M]
- Incremental skip: checks output/classifications/ for existing files
- Defaults to openrouter provider; 2000 max_tokens (Gemini 2.5 Flash
uses ~787 thinking tokens, so 800 was too low)
CLI: markitect infospace classify-summary [--update-metrics]
- Entity type counts + VSM system counts with percentages
- 5 × 6 type × VSM matrix (spots structural blind spots at a glance)
- --update-metrics writes type_distribution, type_entropy,
vsm_type_matrix_cells to metrics.yaml
Config: InfospaceConfig gains classifications_dir (default output/classifications)
Schema: schemas/typed-entity-schema-v1.0.md — type/VSM vocabulary tables,
rationale format rules, validation rules, metrics enabled at L2
infospace.yaml: schemas.typed_entity references typed-entity-schema-v1.0.md
Seed classifications (3): division_of_labour (Process/S1),
natural_price_as_central_price (Principle/S2),
invisible_hand_mechanism (Principle/S4)
