v2.3.0

DeepDoc 2.3.0 is an internal quality and architecture release: the Node.js MDX compile gate subprocess is replaced by inline Python validation, validator checks are demoted to warnings so generation never stalls on stylistic issues, and the marketing site ships a full design-system refresh.

Changed

Generator

• MDX compile gate removed — the external Node.js subprocess (mdx_validator/validate.mjs) that validated generated MDX is replaced by inline Python-side validation. Generation no longer requires a Node.js process at validation time, eliminating subprocess startup overhead and environment-dependency issues on Node-less machines.
• Validator check demotions — most validation checks are now warning-only and no longer trigger Step 6 / Step 6.5 retries. Hard-fails remain only for: truncated output (word_count < 100), leaked placeholders (placeholder_sections), and hallucinated file paths (_check_hallucinated_paths). All other checks — missing sections, low file coverage, out-of-evidence refs, hallucinated symbols, unmatched routes, flow grounding, contract concepts, runtime entities, config keys, integration grounding — log warnings and are recorded in generation_quality.json but do not block the page. See docs/validator_demotions.md for per-check rationale.

Chatbot

• Shared constants centralised — chatbot/constants.py introduced as the single source of truth for shared string literals (chunk types, corpus names, field keys) used across indexer.py, retrieval_mixin.py, answer_mixin.py, and service.py.
• Retrieval and answer cleanup — retrieval_mixin.py and answer_mixin.py updated for the new constants module; dead code and redundant type checks removed across linking.py, live_fallback_mixin.py, docs_summary.py, and settings.py.

Planner

• Topology and refinement updates — topology.py cluster-merging and bucket_refinement.py decomposition logic updated for consistency with the new validator contract; nav_shaping.py and common.py minor cleanups.
• Public API tightened — planner/__init__.py exports trimmed to the canonical public surface; internal helpers no longer exported.

Legacy module removal

• deepdoc/_legacy_types.py deleted — all callers use v2_models.py directly.
• deepdoc/prompts_v2.py re-export facade deleted — callers import from deepdoc/prompts/ directly.
• deepdoc/generator/mdx_validator/ Node.js shim deleted.

Site builder

• scaffold_files.py, mdx_utils.py, engine.py, and templates.py updated for the removed compile-gate and new generator API surface.

Web

• Complete marketing site redesign — new design system: DM Serif Display + DM Sans + JetBrains Mono + Dancing Script cursive wordmark. Chartreuse #C2FF4D accent replacing old cyan. Aurora gradient hero background. Typewriter terminal animation. Upward-drifting code-fragment canvas on the CTA. Light/dark mode toggle with no-flash init. Video container fixed to 16:9. web/src/ added to git tracking.
• Docs page — updated to new design system; all hardcoded old-cyan color references replaced with the new cohesive palette; SVG architecture diagram updated; DM Serif Display headings throughout.

Tests

• test_mdx_compile_gate.py removed (module deleted).
• All other affected test files updated for the new generator, chatbot, and planner APIs.
