v0.2.0

What's Changed

Added

• synto add SOURCE — import PDF, Markdown, and text files as tracked source documents.
  The original is archived in .synto/sources/<id>/. For PDF files, segments are
  extracted immediately into heading-aware chunks and assembled into canonical raw/*.md
  notes for the ingest pipeline. Use --type to specify the document type; --force to
  re-import; --extend-pack remains reserved and is currently a safe no-op.
• Source-type prompt system: built-in prompts for notes, textbook, paper, spec,
  api_docs, web_article, corp_docs, transcript, plus unknown_text fallback are
  loaded during ingest analysis based on the declared source type, steering the fast model
  toward type-appropriate structure and terminology.
• Compile lineage: compile_runs table records every compile job (models, token counts,
  timestamps). Published articles carry a lineage: frontmatter field listing their
  contributing sources and run ID. synto trace article <name> prints the full compile
  history for any article.
• LLM response cache: llm_cache table stores SHA-256-keyed responses. synto maintain --clear-cache flushes all entries; --older-than N prunes entries older than N days.
• Term extraction: extract_terms() and VaultReader.list_terms() added;
  concept_occurrences table (schema v13) links concepts to the source segments they
  appear in.

Fixed

• PDF import now preserves ToC preamble text, surfaces bibliographic metadata into raw-note
  frontmatter, closes extractor resources correctly, and detects duplicate imports by content
  hash instead of filename alone.
• File-based imports are now atomic, and synto add --force correctly replaces prior raw,
  asset, and import state instead of leaving stale artifacts behind.
• synto status now counts imported on-disk raw notes before ingest, so synto add output
  shows up immediately as Raw: new.
• Structured-output recovery now repairs malformed JSON escapes more aggressively, fixing
  live compile failures caused by invalid backslash and malformed \u... sequences.
• Compile cleanup now strips stray [[wikilinks]... placeholder artifacts from generated
  article bodies before draft write.
• Ingest invalidation now respects source-type prompt changes, and imported ### Media
  blocks are stripped before article synthesis.
• Smoke coverage now matches current runtime behavior, including LM Studio model-id
  resolution and the intentional --extend-pack no-op.
