Verify a claim deterministically — returns a verdict (HOLDS / BROKEN / INCOMPLETE), the worked trail, AND a sealed receipt {content_hash, cite_url} you can re-fetch and re-verify (seal_fetch).

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 coverage report returns — per-claim source quote + verdict + trail.

Ranked search over the keeping (the kept library).

Fetch a sealed verification record (the receipt) by its content hash.

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.

Fetch one card (the full record) from the keeping by id.

Browse the keeping — paginated, optional shelf filter.

Counts over the keeping — total, by shelf, by surface.

The deterministic card of the day from the keeping (same all day).

The map: a read-only view of one axis (its scaffold members, depth, neighbors, umbrella children).

The axes that sit on a given scaffold member (dimension).

Cards related to one card — its explicit links + same-shelf siblings.

Find the card for a query — by exact id, then title, else ranked search.

Corpus health — is the keeping loaded and sound (totals, shelves, surfaces).

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

Steward — a household budget (income, expenses -> net, savings rate, by category).

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

Coach — the subjects a learner can study (read / mcguffey / aesop / founding / pilgrims / es / …), each with its unit count.

Coach (K-3 tutor) — one subject's whole path: unit count, tracks, ordered unit briefs.

Coach — one unit, VERBATIM as authored (rule, examples, decodable sentence, checks).

Coach — the next lesson in a subject, deterministically.

Coach — adaptive 'what's next' in a subject: given completed unit ids, the next lesson whose prerequisites are met (grows with the student).

Coach — seal an HONEST INTEGER count of completed units (a receipt for progress, never a grade on the child).

Coach — what it does and the boundary it will not cross (never grades a child).

Mint a SOVEREIGN, PORTABLE identity the person OWNS — {id, public_key, private_key, signing_available}.

Verify a signature over a message against a public key (never raises; True/False).

Derive the stable public fingerprint id from a public key (deterministic).

Issue a badge over already-sealed checks — a re-checkable receipt that points at N seals that STILL STAND.

Re-check a badge from the store — re-verifies every seal it references and returns the count that still stands (N recomputed, not trusted).

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.

Create/extend a shared study (superposition stack) — each entry mints ONE card that lives once and is referenced by key; no duplication.

Export a study as a self-contained, portable bundle (optionally signed).

Import an exported study bundle — re-materializes its cards (each lives once).

Discover pseudonymous shared-study groups by TOPIC (not by person).

A study group: topic, member handles (no ids/PII), and the shared-study cards.

Open a study group around a topic (pseudonymous; a handle, no personal info).

Join a study group (consent-based, pseudonymous; idempotent).

Add a verse/note/question to a group's shared study — attributed to your handle, optionally signed.

Resolve a Scripture reference to its World English Bible text.

Read a passage of the WEB — a single verse, a range (John 3:16-18), or a whole chapter (John 3).

Strong's word study — original-language definition + pronunciation + every occurrence.

Verses connected to a reference by SHARED original words (Strong's) — the dots, connected; deterministic and found, ranked by shared-word count.

Every verse where a Strong's word occurs (the concordance).

Public-domain, attributed commentary (Matthew Henry) on a reference — the commentator's own words, found and cited, never generated.

Editorial cross-references for a verse (openbible.info, CC BY — expansion of the public-domain TSK), ranked by relevance votes.

A Bible figure from Easton's Bible Dictionary (1897, PD) — summary + every verse that speaks of them (found + attributed; category tag is imperfect).

Browse/search Easton's Bible Dictionary (people, places, terms).

Christ-signpost traces (prophecy/cross-cultural pointers to Jesus) — attributed, verdict CONCORDANT/MIXED, NEVER HOLDS (a signpost, not a proof).

Seeds 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).
