Tools

Tools the server advertised in the latest measurement — measured, not catalog-claimed.

vela.corpus.query9 params
Ask the corpus by COORDINATE rather than keyword. Filter works by axis weights (e.g. religion ∈ {T,s} AND work ∈ {T,s} returns the God-and-Work source set across genres), controlled themes, qualities/emotions, genre, and free text. Returns card metadata: the one-line claim, themes, coordinates, qualities. FREE and read-only. [capability: library-extraction-cards · mirrors: POST /api/corpus/query]
- topicstring
- axesobject
- themesarray
- qualitiesarray
- genrestring
- textstring
- include_passagesboolean
- limitinteger
- offsetinteger
vela.corpus.list_topics0 params
List the coordinate systems the corpus can be queried through — each with its thesis, axes, and controlled vocabularies. Call this before vela.corpus.query to learn what axes and themes exist. FREE and read-only. [capability: topic-coordinate-systems · mirrors: GET /api/corpus/topics]
vela.corpus.describe_topic1 param
Describe ONE topic in full — its axes and their operative definitions, its complete controlled theme and quality vocabularies, plus the vocabulary actually IN USE across the corpus with counts. The declared vocabulary and the used vocabulary are different facts; this returns both. FREE and read-only. [capability: topic-coordinate-systems · mirrors: GET /api/corpus/topics/:slug]
- topicstring
vela.corpus.ground_claim2 params · 1 required
Ground a claim in the corpus: hybrid semantic + theme retrieval over real passages, returning citations with source, passage code, scores, and a SHORT snippet. Use to check whether the corpus supports, complicates or is silent on an assertion. COSTS a small amount (one embedding per call). [capability: corpus-ingestion-dual-grade · mirrors: internal — lib/audit/retrieve.ts]
- claimstringrequired
- limitinteger
vela.corpus.witness7 params
Literary Witness Rail (ASN-1577): return passages and one-line claims from Vela's 762-work corpus that illuminate the given themes and/or emotions. Designed for frame-family profile pages — PersonFrame × ProblemFrame × ConditionFrame — to add an inside-out layer (what writers who lived this say) alongside the outside-in portrait the frame join produces. Results carry evidence_grade 'T1' (single-extractor) until PRN-282 lands. FREE for claims; costs one embedding for the passage path. [capability: literary-witness · mirrors: GET /api/vela/witness]

- emotionsarray
- axesobject
- problem_slugstring
- condition_slugstring
- max_passagesinteger
- max_claimsinteger
vela.magazine.sequence_path4 params
Ask what this magazine would actually give a reader who said they wanted these things. Returns the REAL sequenced path with the rationale for each piece — the same core the anonymous intake calls, not a preview. Read-only: writes nothing and records no signal. [capability: adaptive-magazine-engine · mirrors: POST /api/magazine/start-path]
- emotionsarray
- formsarray
- propertystring
- limitinteger
vela.magazine.relation_floor1 param
Whether a magazine's corpus can support the adaptive promise its pages render. Reports, per property, each relational dimension's fill AND its separating power — a field present on every piece with one distinct value carries no information, so fill rate alone is misleading. Read-only. [capability: adaptive-magazine-engine · mirrors: npm run magazine:relation-floor]
- propertystring
get_membership_offer0 params
Returns the Psychology & the Humanities chapter of the Bicycle Cooperative membership offer: five options (enterprise member, practitioner member, worker, practitioner rent, enterprise rent) with chapter substitution applied and this front's join URL.

Availability history

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.

Era history

Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
