1.1.2 - 2026-05-23

Research workflows

The Sources corpus is curated by Steiner-engagement, not by canon — these are the foundational texts the GA itself takes up. A few workflows it makes practical:

• From a Steiner lecture to its source text. find_source_chapters_for_ga_locus("GA 142, 1912-12-28") returns the Sources chapters the curator has linked to that lecture (Bhagavad Gita Discourses, Mahabharata Parvas, the Pauline epistles as the GA 142 counterpart text). fetch_source_chapter then quotes the verses verbatim.
• From a foundational text to Steiner’s treatment of it. fetch_source_summary on (say) the Kaṭha Upanishad or De Anima Book II names the verified GA loci where Steiner engages it; fetch_passage returns his actual words.
• Cross-corpus surveys in a single call. search_anthroposophy(query=..., corpus="all") fans GA + Free Man Creator (FMC) + Sources together, distinguishing hits by [ga] / [fmc] / [sources] tags with per-corpus totals.
• Honest gap-detection. When the curator has examined a chapter and Steiner did not engage it, steiner_status: "not_engaged" is the explicit sentinel — the data says so rather than inviting a fabricated bridge. Aristotle’s De Anima, for example, carries this flag despite the structural temptations to read his hylomorphic soul-account into the threefold-body schema.
• Stream-filtered comparative work. search_sources(stream="indian") scopes to Vedic / Upanishadic / Gita / Mahabharata material; stream="greco-christian" to Patrologia + Aristotle + Aquinas + Hermetic Corpus; stream="western-european" to the Beguine + Rhineland + Theosophical + Goethean strands.
• Curator’s cross-tradition congruences as named syntheses. Each summary surfaces the FMC curator’s explicit cross-tradition observations (e.g. De Anima’s tripartite soul ↔ Vedanta’s pancha-kosha ↔ Plotinus’s nous-triad ↔ Kabbalah’s nefesh / ruach / neshamah) as paraphrase the curator owns, never as quotes from those traditions.

Discipline reminder: only fetch_source_chapter is quote-safe (quote_safe=true). fetch_source_summary, find_source_chapters_for_ga_locus, and every steiner_loci.statement field are FMC-curatorial paraphrase (quote_safe=false) — they capture the verified loci but they never go inside quotation marks.

Added

• /sources/ corpus integration — Sacred, Inspired and Foundational Texts across 5 wisdom-streams (Indian, Persian, Egyptian-Hebrew, Greco-Christian, Western-European). Vedic scripture, the Greek-philosophical tradition (Aristotle, Plato, Plotinus), Patrologia (Church Fathers), Aquinas (Summa Theologiae + Summa Contra Gentiles), Beguine + Rhineland mysticism, Hermetic Corpus, Rosicrucian Manifestos, Theosophical inheritance (Isis Unveiled, Secret Doctrine, Mahatma Letters), Goethean works.
• Tool search_sources: full-text search over /sources/ chapters. Filters: work, lang, edition, stream, tradition, form, year_from, year_to. Returns ranked chapter hits with chapter_locus, snippet, curatorial blurb, and summary_url (when present) pointing at the FMC-curatorial paraphrase block.
• Tool fetch_source_chapter: retrieve verbatim chapter text by chapter_locus (<work>[/<subwork>...]/<chapter>). Returns text_trust='verbatim', quote_safe=true, parent breadcrumbs, descriptor subtitle + blurb, and available_versions[]. Use to obtain quote-safe text from /sources/.
• Tool fetch_source_summary: retrieve the FMC-curatorial paraphrase block for a chapter or work — theme, soul-faculty, Steiner engagement (paraphrase + verified GA loci, or the honesty-gap sentinel “not engaged in the GA corpus”), cross-tradition congruences. text_trust='paraphrase', quote_safe=false. The structural verbatim-vs-paraphrase split that prevents accidental quotation of curator-summary content.
• Tool list_source_works: discovery — enumerate /sources/ works by stream, tradition, form, parent_locus, top_level_only, has_summary. Returns work_locus, name, tradition, year_approx, chapter_count, word_count, landing_url, summary_url.
• Tool find_source_chapters_for_ga_locus: reverse cross-reference (sources → GA). Given a GA locus (GA 142, 1912-12-28) or volume (142), returns which /sources/ chapters cite that lecture, with paraphrase statements. Driven by the sources_ga_xref bridge, populated from chapter and work summaries.
• search_anthroposophy umbrella extended with corpus='sources' and corpus='all'. 'all' fans GA + FMC + sources in a single call with round-robin interleave; 'both' remains the back-compat default (GA + FMC). Response carries sources_total alongside ga_total and fmc_total.
• Tool fetch_fmc_schema_image: returns inline ImageContent for FMC schemas, mirror-first with upstream fallback. Resolves the image-fetch gap where MCP clients could not follow MediaWiki redirects to the upstream JPEGs.

Changed

• Top-of-document Quotation discipline (read first) block in server instructions extended with a /sources/ paragraph. fetch_source_chapter returns quote-safe text (text_trust='verbatim'); fetch_source_summary returns FMC-curatorial paraphrase (text_trust='paraphrase', quote_safe=false) — never quote, even when paraphrasing is tight. Each steiner_loci entry inside a summary names a verified GA locus retrievable via fetch_passage; the surrounding statement is the curator’s paraphrase, not Steiner’s words. find_source_chapters_for_ga_locus returns paraphrase as well.
• search_anthroposophy.corpus enum: ['ga','fmc','both'] → ['ga','fmc','sources','both','all']. Tool description acknowledges sources as a third corpus alongside GA and FMC.
• MCP tools/list returns 14 tools (4 GA + 5 FMC + 5 sources).
• MCP server version and SERVER_VERSION bumped to 1.1.2. Both were stale prior to this release (1.1.0 and 1.0.0 respectively).

Fixed

• scripts/deploy_site.sh parity probe: added retry/backoff (8 attempts, 0.5s × attempt#) to tolerate uvicorn’s multi-worker spawn window. systemctl is-active returned active before all workers had bound to port 8044, causing a false rollback on the 2026-05-22 deploy.
• v2/server/main.py: removed a stale import sources_shared that crashed all 4 anthro-api workers with ModuleNotFoundError on startup (the module is on the MCP service’s path, not the API service’s). The /sources/ REST endpoints remain deferred per the MCP-first pattern; the import was dead code.
• find_fmc_pages_for_ga_locus.inputSchema: removed the top-level anyOf that required either ga_locus or ga_volume. Anthropic’s custom tool API rejects top-level anyOf / oneOf / allOf in input_schema; any agent call that included this tool in its toolset was failing with 400 tools.N.custom.input_schema: input_schema does not support oneOf, allOf, or anyOf at the top level. The field-presence constraint is now enforced in the dispatch handler instead (which already validated the same rule and returned error_code: "missing_argument"). A regression test (test_no_top_level_schema_combinators) sweeps every FMC tool schema for top-level combinators.

1.1.1 - 2026-05-18

Research workflows

This release is the discipline layer that makes corpus citations trustworthy. With 1.1.1 in place:

• Anything inside quotation marks must be byte-for-byte from a corpus retrieval. fetch_passage, fetch_source_chapter, or a quoted_span record with status=stored — minor trimming, smoothing, or dropping a single word counts as paraphrase, even when self-labelled as quoting.
• 0-hit responses carry an authoritative “do not quote” signal. search_steiner / search_anthroposophy / search_sources return corpus_verdict: "NO_MATCH — ..." in the response payload when total == 0. A researcher receiving a NO_MATCH answer can trust that the topic is genuinely not in the corpus rather than worry the agent gave up too early.
• Bare GA-volume-and-year citations are rejected as unverified. A claim like “GA 26, 1924” without a specific lecture-date or passage-number does not survive the discipline check.
• Reverse-lookup questions get the dedicated tool. “Which FMC pages cite GA 146, 1913-06-02?” routes to find_fmc_pages_for_ga_locus, not generic FTS — exact-locus questions answered by an exact-locus tool.

For research this means citations in an agent’s output reflect retrieval rather than training memory or hallucination, and a “not in corpus” answer can be trusted as authoritative.

Added

• corpus_verdict field on search_steiner and search_anthroposophy responses when total == 0. Carries an authoritative “do not quote” signal in the response payload, so the agent reads it directly rather than relying only on session-level instructions.

Changed

• New top-of-document Quotation discipline (read first) block in server instructions. Requires search_steiner → fetch_passage before opening quotation marks. 0-hit corpus results are authoritative. Bare GA-number-plus-year citations (e.g. “GA 26, 1924”) rejected as unverified. Byte-for-byte means byte-for-byte: dropping a single word (‘thus’, ‘then’, ‘also’) or trimming for slide-readability breaks verbatim status; self-labeling a paraphrase doesn’t exempt it.
• Additional agent-discipline blocks in server instructions: inline citation rendering at parity with web-source linking; section references must use <page_slug>#<section_anchor> form; reverse cross-reference questions must use find_fmc_pages_for_ga_locus; stay inside the corpus when verify_locus returns true; citation follow-ups must verify both page and section anchor before answering.
• Tool find_fmc_pages_for_ga_locus: description lead rewritten around the question pattern it handles (“which FMC pages cite this lecture?”); routes away from search_anthroposophy for reverse-lookup queries.
• Tool search_anthroposophy: closing “When NOT to use this tool” block redirects exact-locus reverse lookups to find_fmc_pages_for_ga_locus.
• Shared FMC source-discipline contract (in search_anthroposophy + fetch_fmc_page descriptions): closing Quotation-marks discipline sentence reserves quotation marks for quoted_span records with status='stored' or verbatim Steiner passages from fetch_passage.

Fixed

• find_fmc_pages_for_ga_locus.inputSchema now declares anyOf requiring ga_locus or ga_volume. Was permissive on {}.
• Removed dead corpus argument from search_steiner / fetch_passage / fetch_parallel dispatch. Handlers pass corpus="steiner" as a literal. fetch_parallel.inputSchema no longer advertises the single-value corpus enum.

1.1.0 - 2026-05-14

Research workflows

This release brings the Free Man Creator (FMC) curatorial layer (anthroposophy.eu — pages, schemas, structured quoted-span records, and GA cross-references) onto the same MCP surface as the GA. Workflows it makes practical:

• Which FMC pages cite this lecture? find_fmc_pages_for_ga_locus("1913-06-02-GA146") returns the reverse cross-reference with attribution class (adjacent / section-inferred / main-body-reference).
• What does the FMC curator say about X? fetch_fmc_page("Krishna_impulse") returns ordered curatorial chunks (lead, sections, subsections, discussion notes) plus quoted_span records with provenance.
• Show me schema FMC00.NNN. fetch_fmc_schema("FMC00.389A") returns description, image URL, linked pages, and cited GA loci.
• What’s the link-graph around a page? traverse_anthroposophy_links runs BFS over the FMC cross-link graph (depth 1-3, configurable max-nodes).

FMC content is CC-BY-SA paraphrase; quoted_span records carry the curator’s structured provenance (status=stored for inline verbatim, status=referenced for GA pointers that resolve via fetch_passage). The unified search_anthroposophy umbrella ranks GA + FMC hits together for queries spanning both.

Added

• FMC (anthroposophy.eu) corpus integration. The curatorial wiki at anthroposophy.eu is now retrievable through the MCP connector alongside the Gesamtausgabe. License: CC-BY-SA.

• Tool search_anthroposophy: unified full-text search across the GA and FMC corpora. Filters: corpus, chunk_class, target_corpus, status, page_slug. Inherits GA filters (lang, edition, ga, ga_range, from_date, to_date). Detects ranking mode from query content (primary_seeking, comparative, curatorial, default) and adjusts interleave order accordingly.

• Tool fetch_fmc_page: retrieve an FMC page by slug. Returns ordered curatorial chunks (lead, sections, subsections, discussion notes), quoted_span records with provenance, and the page’s GA cross-references.

• Tool fetch_fmc_schema: retrieve a schema by FMC00.NNN id. Returns description, image URL, linked pages, and cited GA loci.

• Tool traverse_anthroposophy_links: BFS over the FMC link graph from a root page slug. Depth clamped to [1, 3]; configurable max_nodes.

• Tool find_fmc_pages_for_ga_locus: reverse cross-reference. Given a GA locus (1913-06-02-GA146) or volume (146), return all FMC pages that cite it with attribution class (adjacent, section-inferred, main-body-reference).

• Source-discipline contract enforced in tool response structure. quoted_span records with status=referenced carry no verbatim text; agents follow target_locus to the primary corpus. Records with status=stored carry the full embedded_attribution chain. All FMC retrieval results carry primary_anchor (corpus, page_url, curator, license) and content_hash for citation stability.

Changed

• MCP tools/list returns 9 tools (4 GA + 5 FMC).

1.0.0 - 2026-05-07

Research workflows

The initial release puts the complete Gesamtausgabe (GA 1 through GA 354, public domain) behind a single MCP surface. Workflows it makes practical:

• Search the full corpus by keyword. search_steiner runs FTS5 with Porter stemmer + diacritic normalization. Filters: lang, edition, ga, ga_range, from_date, to_date.
• Verify a GA reference exists before citing. verify_locus confirms (ga, lecture_date) is in the corpus — useful as a citation gate before publishing or quoting.
• Retrieve any passage verbatim. fetch_passage(ga, lecture, passage_number, lang, edition) returns text + stable citation URL in either German original or available English translation.
• View parallel translations side-by-side. fetch_parallel returns multiple editions of the same locus; per-edition translator + year + basis are surfaced, and an alignment_confidence flag warns when paragraph counts diverge between source and translation.

Multilingual support means a researcher reading the German can cross-check the English, and vice versa. Browseable HTML lives at /v1/steiner/<lang>/ga/<vol>/<date>/p<NNN> with content-negotiated JSON via the .json suffix. The MCP surface is anonymous and per-IP rate-limited at the edge — no account, no signup.

Added

• Initial public release.

• Gesamtausgabe corpus (GA 1 through GA 354). Rudolf Steiner’s books, lectures, and lecture cycles. Public domain.

• Multilingual retrieval. English translations alongside German originals. Per-edition tracking (translator, year, basis). alignment_confidence flag marks paragraph-count divergence between source and translation.

• MCP server at https://anthroposophy.ai/mcp. Streamable HTTP transport per MCP spec 2025-03-26. Anonymous access; per-IP rate limiting at the edge.

• Tool search_steiner: FTS5 search over the Gesamtausgabe. Porter stemmer with diacritic normalization. Filters: lang, edition, ga, ga_range, from_date, to_date, corpus.

• Tool verify_locus: confirm a GA reference exists in the indexed corpus before citing.

• Tool fetch_passage: retrieve a verbatim Steiner passage by (ga, lecture, passage_number, lang, edition). Returns text and a stable citation URL.

• Tool fetch_parallel: retrieve the same passage across multiple translation editions side-by-side.

• REST API at https://anthroposophy.ai/v1/.

• Browseable passages at /v1/steiner/<lang>/ga/<ga_volume>/<lecture_date>/p<NNN>. Content negotiation returns HTML to browsers, JSON to agents via the .json suffix.
