101 tools

• verify

  [CHECK · door] Verify a claim deterministically — returns a verdict (HOLDS / PARTIAL / BROKEN / INCOMPLETE / SYSTEM_ERROR), the worked trail, AND a sealed receipt {content_hash, cite_url} you can re-fetch and re-verify (seal_fetch). Three forms: (a) PLAIN — {claim}: a plain-langu

• audit

  [CHECK · door] Audit 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 coverag

• seal_fetch

  [CHECK · door] Fetch a sealed verification record (the receipt) by its content hash.

• find_verifier

  [CHECK · door] Which verify DOMAIN handles a plain-language claim — the deterministic resolver (no model). Returns ranked domain candidates with the literal words that matched, to confirm and pass to `verify`. Crisis defers to real help; genuine ambiguity returns the candidates,

• attest_record

  [CHECK · internal] Bind your identity to a record you already hold — phase 2 of the sovereign flow. Do the thing unsigned (badges_issue, study_export, group_contribute), take the returned content_hash, sign THAT hash with your own key on your own machine, and submit only the atte

• candidate_commit

  [CHECK · internal] Candidate Engine step 1 — commit a COMPLETE raw candidate set BEFORE any evaluation. Give the query, the generator, the method, and EVERY raw candidate; weights ride verbatim as UNTRUSTED metadata (proposal_weight is never confidence and never ranks anything).

• candidate_get

  [CHECK · internal] Fetch 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. The seal proves process integrity, never truth.

• candidate_narrow

  [CHECK · internal] Candidate 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

• kernel

  [CHECK · internal] THE GATE KERNEL — the law you keep here, in one call. The five moves (find, distinguish the KIND, verify what can be verified, preserve the trail, never silently upgrade authority), the eight-rule agent covenant, the six object KINDS, the authority lattice (qua

• kernel_gate

  [CHECK · internal] Route 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). CONFIRMED needs a real verifi

• manufacture

  [CHECK · internal] The Conductor's shop-domain calc door: route an engineering claim + its numbers through the engine's manufacturing verifier -> seal -> hash-chained ledger, and report the disposition (CALCULATED/CONTROLLED/PROVISIONAL/OPEN). The engine verifies the calc; the en

• profession

  [CHECK · internal] Read a sealed profession of faith and who has borne witness to it (each signature re-verified as read), with the lineage it joins — up to Polycarp, the initial trajectory, and Christ at the head. Omit the hash to see the Polycarp root itself.

• redact

  [CHECK · internal] Strip 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. For true privacy run this on a LOCAL/sovereign engine (the text never leaves your machine) or us

• report

  [CHECK · internal] Report a community item (group_contribution, mesh_message, door_note) to the moderation floor. One report is a claim, never a verdict; at three DISTINCT reporters the item is held for a HUMAN steward's review (Deut 19:15). The counter never judges — it decides

• resolve

  [CHECK · internal] Resolve a Scripture reference to its World English Bible text.

• self_attest

  [CHECK · internal] Record 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.

• witness_profession

  [CHECK · internal] Bear witness to someone's sealed profession of faith — sign its content_hash on your own machine (signing.sign_seal) and submit only the attestation. One signature is a claim; two or three witnesses begin to establish a matter (Deuteronomy 19:15). Refuses any r

• witnesses

  [CHECK · internal] Who has borne witness to a record, each signature re-verified as it is read (storage is never trusted). Reports invalid entries rather than hiding them.

• search

  [FIND · door] Ranked search over the keeping (the kept library).

• card_get

  [FIND · door] Fetch one card (the full record) from the keeping by id.

• lookup

  [FIND · door] Look up a VALUE deterministically from the engine's offline, public-domain data — the found-value twin of `verify` (look it up, then verify it), consolidated like verify into one tool. kind is one of: molar_mass {formula}, element {symbol|name|atomic_number}, conver

• define

  [FIND · door] The dictionary — what an English word MEANS. Webster's 1913 (public domain) plus our gathered supplement for terms it predates; each sense labeled with its source. Empty when the word is unknown or no dictionary is loaded. The peer of thesaurus (synonyms) and word_s

• card_connections

  [FIND · internal] Cards related to one card — its explicit links + same-shelf siblings.

• cards_browse

  [FIND · internal] Browse the keeping — paginated, optional shelf filter. Returns card briefs.

• cards_stats

  [FIND · internal] Counts over the keeping — total, by shelf, by surface.

• daily_card

  [FIND · internal] The deterministic card of the day from the keeping (same all day).

• grid_axis

  [FIND · internal] The map: a read-only view of one axis (its scaffold members, depth, neighbors, umbrella children). Omit `axis` for an overview of all axes.

• grid_dimension

  [FIND · internal] The axes that sit on a given scaffold member (dimension).

• locate

  [FIND · internal] Find the card for a query — by exact id, then title, else ranked search.

• pronounce

  [FIND · internal] A synthesized pronunciation guide (respelling + approximate IPA) for a transliteration or word — honestly labeled, not a native speaker.

• thesaurus

  [FIND · internal] The thesaurus — WordNet synonyms and broader (IS-A) terms for a word; the words that stand with it. Empty when the word is unknown or no thesaurus is loaded. The agent twin of the GET /thesaurus page.

• capabilities

  [FIND · plumbing] The live capability statement: what this engine can verify, what tools and endpoints exist, how large the keeping is, and where its boundaries are. Every count is computed at call time and carries a 'means' line defining exactly what was counted — never a hand-m

• library_health

  [FIND · plumbing] Corpus health — is the keeping loaded and sound (totals, shelves, surfaces).

• now

  [FIND · plumbing] The 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. Your own sense of 'today' is months old; this is the correction. Never cached; unresolvable zones are

• steward_budget

  [FIND · plumbing] Steward — a household budget (income, expenses -> net, savings rate, by category). Shows and plans; NEVER moves money.

• steward_cost_destroyed

  [FIND · plumbing] Steward — cost destroyed: money you did NOT spend (was -> now), kept in your currency.

• ask

  [WALK · door] Bring anything — a question, a claim to check, a word to study, or what is actually on your mind. The engine discerns what KIND of thing you brought and answers in kind: it finds and verifies, and declines rather than guessing. This is also the door: if what you ask

• discern

  [WALK · door] Discern what to do with anything WITHOUT doing it — the proposal half of the engine, laid open. Bring a claim, a question, or a messy statement; get back what KIND it is, the necessary claim reduced to only what could change a verdict (private and framing context he

• coach_next

  [WALK · door] Coach — the next lesson in a subject, deterministically. Omit `after` for the first unit; pass a unit id for the one that follows it. `subject` selects the path.

• coach_guidance

  [WALK · internal] Coach — what it does and the boundary it will not cross (never grades a child).
