v0.9.0 — Rich Document Ingestion & chunk_rag Baseline

  • 📄 Rich Document Ingestion — he parse / he feed now accept PDF, Word, PowerPoint, Excel, HTML, CSV/JSON/XML, EPUB and more via the optional ingest extra (pip install "hyperextract[ingest]", powered by MarkItDown). Non-UTF-8 text (GBK, etc.) is auto-detected; text-less (scanned) PDFs fail with a clear OCR hint instead of silently ingesting garbage.
  • 🧱 chunk_rag Baseline Method — a new zero-extraction method: documents are chunked and embedded as-is, and search returns raw text chunks. Zero LLM cost at ingestion, with full provenance (tags, scoped search, per-document rollback). The chunk-retrieval baseline for corpus Q&A and method benchmarking.
  • 🐛 Fixes — he tag crashed on every knowledge abstract (tag_source was never exposed on any type); he search/he talk/he feed/he remove --document crashed on method-built KAs (method/* templates were not resolvable from KA metadata).

v0.8.1 / v0.8.2

  • 🏷️ Source Tags & Scoped Search — he tag ./ka/ --source doc-1 --add legal, then he search ./ka/ "query" --tag legal to retrieve only within tagged documents. Works for graph, hypergraph, and set KAs. (#89, #84)
  • 🛡️ Input Validation — he parse / he feed now reject unsupported file types with a conversion hint instead of silently ingesting garbage. (#88)
  • 📦 Document Archive Fix — re-feeding the same source from a differently-named file no longer accumulates stale copies. (#89)

v0.8.0

  • 🔄 Document Upsert — re-feed an attributed document and its previous version is rolled back automatically: removed facts disappear, shared keys re-merge from surviving sources. (#84)
  • 📁 Per-File Source Attribution — he parse ./docs/ attributes each file by its name automatically; roll back or audit any single file later. An explicit --source still overrides.
  • ⏱️ Spatiotemporal Provenance — temporal/spatial/spatio-temporal graphs fully support source attribution and rollback, with deterministic (MERGE_FIELD) replay tests.

v0.5.0 – v0.7.0

  • 🗑️ Two-Tier Knowledge Deletion — hard-delete by key (he remove --node/--edge, orphan edges pruned) or remove a single wrong fact via LLM-assisted editing (he remove --edit-node --fact), with dry-run, key-invariance checks, and automatic backups. (#84)
  • 📜 Source Attribution & Provenance — he feed --source / he parse --source record each document's raw contributions; he remove --document rolls back exactly what one document contributed; he info --sources shows the ledger. (#84)
  • 📈 Incremental Everything — feed/parse/removal/edit patch the vector index in place (only affected vectors re-embedded); he feed skips documents whose content hash is unchanged (--refeed to force). (#84)
  • 🧪 he template validate — catch semantic template errors before paying for LLM calls: 9 diagnostic rules, --json for CI, --all for directories. (#77)
  • 📊 GraphML & CSV Export — desktop graph tools and spreadsheets; hypergraphs get a hyperedges table. (#85)
  • 🌐 OrcaRouter Provider — one key for 150+ models via create_client("orcarouter"). (#71)
  • 🔐 Config File Permissions — ~/.he/config.toml saved 0600. (#86)
  • 🔗 Obsidian wikilink fix — aliases no longer break on [ ] | # ^. (#87)
  • 🛡️ Chunk-Level Fault Isolation — one failed chunk no longer discards the rest of a multi-chunk extraction. (#78)
  • ⚡ MCP Python SDK 2.x — he-mcp works on mcp 1.x and 2.x. (#72, #82)
  • 🔀 Directed-Edge Fix — (source, target) order preserved; custom endpoint field names. (#74)
  • 🔑 DeepSeek API Key Fix — DEEPSEEK_API_KEY honored on the OpenAI-compatible path. (#76)
  • 🎓 Education Templates — course_concept_graph + curriculum_structure. (#80)
  • 🧭 Smaller Fixes — Graph_RAG.search 3-tuple; he talk -i --top-k; onboarding/docs overhaul. (#70, #73, #57)
