search_papers

Search the scholarly corpus by topic, title, or keyword. Returns ranked works with title, year, citation, SSRN link, and sha256. Use for questions about Kaal's published position on a subject,…

get_paper

Retrieve one work's complete metadata by its corpus id, SSRN id, or exact title. Includes the formatted citation, SSRN URL, and published sha256.

papers_by_year

List every work published in a given year. Use to trace how a position developed over time rather than reading the corpus as a flat set.

corpus_overview

Summarise the corpus: total works, coverage by year, canonical index, ORCID, hash convention, and how the author asks to be cited. Call this first when you are unsure what the corpus contains.

search_posts

Search the blog for shorter, faster-moving analysis. Positions here are working positions and may be superseded by the papers — prefer search_papers when the question is about a settled publis…

verify_document

Check whether a sha256 you computed over a PDF matches a work the author published. Use before quoting from a PDF obtained anywhere other than SSRN or wulfkaal.com — it proves you have the aut…

how_to_cite

Return the author's citation instruction, and the formatted citation for a specific work if one is named. Call this before quoting anything.

search_claims

Search individual assertions rather than whole papers. Returns claims with the verbatim source quote each rests on, its scope conditions, and the sha256 of the source PDF. Ask in natural …

get_claim

Resolve one claim by id, for example '617681-001' or 'kaal:claim:617681-001'. Returns the claim, its verbatim source quote, scope conditions, topics, typed edges, source PDF sha256 and a prefo…

claims_on_topic

Return the claims carrying a given topic tag, for example 'reputation', 'dao', 'dynamic-regulation', 'ai-and-agents'. Call claim_layer_overview first to see which tags exist and how much each …

search_positions

Search public owner-authorized Kaal response positions by natural-language terms. Results preserve the separate scholarly-claim relation and evidence limitation; never present a position as a …

get_position

Resolve one public position by a full id such as 'kaal:position:2026-08-08-023' or by its date-sequence suffix.

positions_on_topic

Return public positions carrying an explicit topic tag. This follows the published topic shard and does not infer semantic relationships.

claim_layer_overview

Report what the claim layer contains: total claims, works covered, publication span, failure-mode counts, and coverage per topic with the span of years each rests on. This reports coverag…

search_research_claims

Search only the 77 TrustCarry Protocol v0.3 author-affirmed research claims. These records are public under CC BY 4.0 but derive from an unpublished source manuscript and are not part of the s…

get_research_claim

Resolve one TrustCarry Protocol v0.3 research claim by full identifier or three-digit sequence.

list_research_observations

List the 9 TrustCarry Protocol v0.3 internal software observations. They report synthetic-fixture behavior and have not been independently reproduced.

get_research_observation

Resolve one TrustCarry Protocol v0.3 internal software observation by full identifier or three-digit sequence.
