Add nodes/scene_validator_node.py: SceneValidatorNode, a thin adapter that
delegates to validate_scene (MASTER_SPEC §20).
- Required input scene (SCENE model, serialized via to_json); optional config
(COMPILER_CONFIG) defaulting to Config() when unconnected.
- Outputs (scene, warnings, errors): the validated SCENE plus warnings/errors
passed through unchanged. No compiler logic in the node.
- Registered as SceneCompilerValidator ("Scene Validator").
Tests: node metadata/inputs, valid scene pass-through, delegation + message
surfacing + config threading (monkeypatched), default config when absent, and
ComfyUI registration.

Add the Scene Validator per MASTER_SPEC §14 and a central message-code registry.
- compiler/common/message_codes.py: single source of truth for message codes
(Appendix B SC0001-SC0014 plus documented extensions SC0015 Unexpected Field
Removed, SC0016 Empty Concept Removed, SC0017 Interaction Dropped) with a
message() factory that pins each code's severity and title.
- compiler/validator/scene_validator.py: validate_scene(scene_json, config,
logger=None) -> CompilerResult.
- Strict schema validation classifies failures: missing required -> SC0009,
wrong type/malformed -> SC0002 (Errors that stop the compilation).
- Recoverable normalization: unexpected fields -> SC0015 warning + removed
(suppressed when config.validator.allow_unknown_fields is true); empty/
whitespace concepts -> SC0016 warning + removed after trimming; interactions
whose participants reference a non-existent character -> SC0017 warning +
dropped.
- Never creates concepts, generates tags, or does KB lookup. Output is a
Scene model wrapped in a CompilerResult; order is deterministic.
New warning codes (SC0015-SC0017) are extensions to be folded into Appendix B.
Tests: valid input, hard errors (SC0009/SC0002) that stop, recoverable warnings
(SC0015/SC0016/SC0017), allow_unknown_fields suppression, determinism, and the
code registry.

Define the nine JSON Schemas (draft 2020-12) exchanged between compiler stages
per MASTER_SPEC §10–§11, plus a reusable validation helper.
Schemas (schemas/json/, cross-referenced by $id):
- scene, character, concept, interaction, metadata, knowledge_base_entry,
resolved_tag, category_map, prompt_output
- Scene requires all seven sections (collections may be empty); Concept is a
bare string or an object with required name; Character has an integer id plus
seven concept arrays; Interaction has integer participants and a concept.
- Each schema carries a major.minor version; unknown fields rejected by default.
Helper (schemas/validation.py):
- validate_document(doc, schema_name, *, allow_unknown=False) -> list of
structured ValidationIssue (empty = valid); collects all errors.
- Loads all schemas into a referencing registry so cross-schema $ref resolves.
- allow_unknown relaxes additionalProperties per config without duplicating
schemas (schema-valued additionalProperties, e.g. Category Map, is preserved).
Tests: valid + several invalid documents per schema, unknown-field toggle,
unknown-schema error (34 assertions). Bumps jsonschema to >=4.18 for referencing.

Scaffold the Phase 0 foundation per MASTER_SPEC §24:
- Directory layout: nodes/, compiler/{analyzer,validator,resolver,splitter,
builder,common}/, knowledge_base/, schemas/, prompts/, config/,
tests/{analyzer,resolver,validator,integration,regression}/, examples/,
scripts/, docs/.
- pyproject.toml targeting Python 3.11+, jsonschema as the single runtime dep,
ruff + pytest as dev deps, explicit package list, and ruff/pytest config.
- ruff for linting and formatting; pytest with repo root on pythonpath.
- GitHub Actions CI running install, ruff lint, ruff format check, and pytest
on Python 3.11 and 3.12 for pushes and pull requests.
- docs/ skeleton and CONTRIBUTING.md referencing the wiki.
- Layout test asserting the §24 structure and package importability.
