verifyVerify a claim deterministically — returns a verdict (HOLDS / BROKEN / INCOMPLETE / SYSTEM_ERROR), the worked trail, AND a sealed receipt {content_hash, cite_url} you can re-fetch and re-verify (seal_fetch).
Inferred read-onlyauditAudit a whole text: deterministic extractors find every checkable quantitative claim (sums, percentages, hourly/annual pay, compound interest, rule-of-72, elapsed years, day-of-week, leap years, nutrition labels), the engine verifies the lot, and ONE sealed coverage report returns — per-claim source quote + verdict + trail.
Potential side effectsredactStrip PII (emails, SSNs, credit cards, IPs, URLs) from text to stable placeholders before you pass it onward; the mapping is returned so YOU reveal replies locally.
Inferred read-onlydecksThe decks — curated card SETS, both by-situation (need decks, frontloaded for a moment of need like 'when the power goes out') and by-domain.
Inferred read-onlydeck_openOpen a deck to its frontloaded hand — the cards that situation calls for, in order, with NO query needed.
Inferred read-onlygrid_axisThe map: a read-only view of one axis (its scaffold members, depth, neighbors, umbrella children).
Inferred read-onlycard_connectionsCards related to one card — its explicit links + same-shelf siblings.
Inferred read-onlylibrary_healthCorpus health — is the keeping loaded and sound (totals, shelves, surfaces).
Inferred read-onlypronounceA synthesized pronunciation guide (respelling + approximate IPA) for a transliteration or word — honestly labeled, not a native speaker.
Inferred read-onlysteward_budgetSteward — a household budget (income, expenses -> net, savings rate, by category).
Inferred read-onlysteward_cost_destroyedSteward — cost destroyed: money you did NOT spend (was -> now), kept in your currency.
Inferred read-onlycoach_subjectsCoach — the subjects a learner can study (read / mcguffey / aesop / founding / pilgrims / es / …), each with its unit count.
Inferred read-onlycoach_overviewCoach (K-3 tutor) — one subject's whole path: unit count, tracks, ordered unit briefs.
Inferred read-onlycoach_unitCoach — one unit, VERBATIM as authored (rule, examples, decodable sentence, checks).
Inferred read-onlycoach_recommendCoach — adaptive 'what's next' in a subject: given completed unit ids, the next lesson whose prerequisites are met (grows with the student).
Inferred read-onlycoach_masteryCoach — seal an HONEST INTEGER count of completed units (a receipt for progress, never a grade on the child).
Inferred read-onlycoach_guidanceCoach — what it does and the boundary it will not cross (never grades a child).
Inferred read-onlyidentity_createExplains how to create a SOVEREIGN identity — keys are born on the USER'S device (never on the server; no private key crosses the wire).
Potential side effectsidentity_verifyVerify a signature over a message against a public key (never raises; True/False).
Potential side effectsidentity_fingerprintDerive the stable public fingerprint id from a public key (deterministic).
Inferred read-onlybadges_issueIssue a badge over already-sealed checks — a re-checkable receipt that points at N seals that STILL STAND.
Inferred read-onlybadges_verifyRe-check a badge from the store — re-verifies every seal it references and returns the count that still stands (N recomputed, not trusted).
Inferred read-onlyself_attestRecord a person's OWN words about their study — a DISTINCTLY TYPED record that can NEVER count as a sealed check or satisfy an auto-graded requirement.
Inferred read-onlystudy_createCreate/extend a shared study (superposition stack) — each entry mints ONE card that lives once and is referenced by key; no duplication.
Potential side effectsstudy_importImport an exported study bundle — re-materializes its cards (each lives once).
Inferred read-onlygroup_getA study group: topic, member handles (no ids/PII), and the shared-study cards.
Inferred read-onlygroup_createOpen a study group around a topic (pseudonymous; a handle, no personal info).
Inferred read-onlygroup_contributeAdd a verse/note/question to a group's shared study — attributed to your handle, optionally signed.
Inferred read-onlycalendar_createCreate ONE event in a human's calendar — the pilot on-behalf write, and the only one.
Potential side effectsconsent_checkCheck whether a human has authorized YOU (this agent's key fingerprint) for a named verb — the agent covenant's 'request human authorization before writes'.
Inferred read-onlycommons_readWhat the fellowship has put on the commons — promoted member work, newest first.
Inferred read-onlyplaybook_readTHE PLAYBOOK — the Body's testimony of faithful obedience: 'Canon commands, Playbook remembers.' List entries (optionally by `status` quarantine/confirmed/rejected/pruned or `author`), or one by `id`.
Inferred read-onlyplaybook_signableStep 1 — the exact bytes to sign ON THE DEVICE for a Playbook write.
Potential side effectsplaybook_submitStep 2 — verify your detached signature over those exact bytes and enter the testimony/event.
Inferred read-onlymoderation_signableStep 1 of a report or a block: the exact canonical bytes to sign with your own key, on your own machine.
Inferred read-onlywant_openAsk the library to ACQUIRE something it does not hold (kind=missing, give query) or to EXPAND a thin card (kind=expand, give card_id).
Inferred read-onlywants_listThe library's desiderata desk — open wants, sorted by demand, agent plane marked and separate.
Inferred read-onlywant_offerReturn to the comb with a FOUND source for an open want: label + url + snippet, attributed.
Inferred read-onlyreportReport a community item (group_contribution, mesh_message, door_note) to the moderation floor.
Inferred read-onlyattest_recordBind your identity to a record you already hold — phase 2 of the sovereign flow.
Inferred read-onlywitnessesWho has borne witness to a record, each signature re-verified as it is read (storage is never trusted).
Inferred read-onlynowThe actual current date and time, fresh at this call — UTC (the clock every seal is stamped in), the library's home zone, and optionally any IANA zone you name.
Inferred read-onlycapabilitiesThe live capability statement: what this engine can verify, what tools and endpoints exist, how large the keeping is, and where its boundaries are.
Inferred read-onlykernel_gateRoute ONE proposed state-change through the kernel and get back the verdict (REJECT / QUARANTINE / CONFIRMED) plus the nine-field record — so you can DISCERN before you write (covenant rule 8: stop when the evidence is incomplete).
Potential side effectsmesh_mapThe believers immediately around you in the Fellowship Mesh — your view only, never a global map.
Inferred read-onlymesh_inboxThe messages that reached you, each carrying its own offline verification so you trust it by proof rather than by this server's word.
Inferred read-onlymesh_doorRead the words left on YOUR door — the whiteboard others wrote to you, each with its verification.
Inferred read-onlymesh_signableStep 1 of speaking to your fellowship: get the exact canonical bytes to sign for a message (returned base64url, with the nonce and created_at to send back).
Potential side effectsmesh_leave_on_doorLeave a word on one believer's door — directed encouragement rather than a post to everyone near you.
Potential side effectsmesh_postStep 2: speak to the nodes around you, carrying only your SIGNATURE — your private key never leaves your machine and this tool will not take one.
Inferred read-onlyaskBring anything — a question, a claim to check, a word to study, or what is actually on your mind.
Inferred read-onlydiscernDiscern what to do with anything WITHOUT doing it — the proposal half of the engine, laid open.
Inferred read-onlycandidate_commitCandidate Engine step 1 — commit a COMPLETE raw candidate set BEFORE any evaluation.
Inferred read-onlycandidate_narrowCandidate Engine step 2 — narrow a COMMITTED set: verifiers are assigned under the fixed pre-registered routing policy (never your choice — that is what stops verification shopping), each routed claim runs through the deterministic moat, unroutable claims stay quarantined (held, never judged), and the FULL set — rejected and quarantined included — is sealed with its ordered trace.
Inferred read-onlycandidate_getFetch a sealed candidate record (a narrowing receipt or a commitment anchor) by its content hash — the whole preserved path, losers included, re-checkable offline with tools/verify_seal.py.
Inferred read-onlyread_passageRead a passage of the WEB — a single verse, a range (John 3:16-18), or a whole chapter (John 3).
Inferred read-onlyword_studyStrong's word study — original-language definition + pronunciation + every occurrence.
Inferred read-onlycross_referencesVerses connected to a reference by SHARED original words (Strong's) — the dots, connected; deterministic and found, ranked by shared-word count.
Inferred read-onlycommentaryPublic-domain, attributed commentary (Matthew Henry) on a reference — the commentator's own words, found and cited, never generated.
Inferred read-onlytsk_cross_referencesEditorial cross-references for a verse (openbible.info, CC BY — expansion of the public-domain TSK), ranked by relevance votes.
Inferred read-onlycharacter_getA Bible figure from Easton's Bible Dictionary (1897, PD) — summary + every verse that speaks of them (found + attributed; category tag is imperfect).
Inferred read-onlyprophecy_tracesChrist-signpost traces (prophecy/cross-cultural pointers to Jesus) — attributed, verdict CONCORDANT/MIXED, NEVER HOLDS (a signpost, not a proof).
Inferred read-onlyharmonyHarmony of the Gospels — one event of Christ's life, every gospel that records it, side by side (found, verbatim WEB text, never generated).
Inferred read-onlytimelineTimeline — Old Testament, New Testament (Acts onward), and Church History, one spine from creation to today.
Inferred read-onlybackmatterBack-matter reference tables: weights_measures, names_of_god, parables, miracles, book_intros, topical_index.
Inferred read-onlybible_placesThe Atlas — biblical places with REAL coordinates, honestly held: located places carry lat/lon (cross-checked against an independent gazetteer); disputed sites (Mount Sinai, Cana, Golgotha) NAME their candidates instead of planting one flag; unlocatable places (Eden, Emmaus, Tarshish, Ophir) are honest blanks with no coordinates.
Inferred read-onlynarrativesThe storyboards — the common narratives charted in the Bible FIRST (exile-and-return, the barren woman bears, down-to-the-pit-raised, the great reversal...), each instance real people with verified refs.
Inferred read-onlystudy_findThe quick-find index — ONE lookup across the whole reference section: archetypes, storyboards, movements, the six study tables, the atlas, harmony, timeline, and the encyclopedia.
Inferred read-onlyoriginal_wordsThe original-language words behind a verse (Hebrew/Greek, with Strong's where known) — FOUND in the lexicon, never generated.
Inferred read-onlycanonThe canon as concentric layers — the undisputed 66 that all major traditions share, plus the books held BEYOND it by particular traditions, each framed on its own layer and never merged.
Inferred read-onlyteachingsThe teachings of Christ (Words in Red) — the frozen Greek anchor plus the history that ALIGNS to each teaching, gathered and attributed, never authored.
Inferred read-onlyseedsSeeds of the Word (the Areopagus / logos spermatikos pass) — true fragments mined from the nations, ATTRIBUTED, CONCORDANT/signpost NEVER HOLDS; each names the idol it refuses and points to Christ (Acts 17; 1 John 4:1-3).
