v0.7.0

Added

• Learning, with the assistant as a tutor. A new Learning page, and the
  same in the chat ("teach me fractions for a ten-year-old", "quiz me",
  "what should I revise?"). Name any topic and a level — child, beginner,
  intermediate or advanced — for a lesson in one clear shape: the goal, what
  to know first, small steps each with a worked example, common mistakes,
  questions to check yourself with their answers folded away, and what to
  learn next. Practice questions (choices, numbers, short answers) come one
  at a time without their answers. Answers are marked by rules wherever a
  rule can tell — a letter or the option's words, a number however it is
  written (12,5, 1/3, "120 cm"), a short answer whatever its capitals — and
  otherwise judged by the model against the expected answer, or by you when
  there is no model. Missed questions come back in minutes, right ones
  tomorrow, then in three days, a week and a month, until they count as
  learnt; the page lists every topic with its progress and what is due. A
  tutor specialist teaches with only these tools and reading, never writing.
• Research with sources. A new Research page, and the same in the chat
  ("research … with sources"). The assistant plans the searches, reads the
  best sources it finds — official and scholarly first, forums last, never
  more than two pages from one site — and writes a report from them only: a
  short answer, what the sources say, where they disagree and what they do
  not settle, with a number after every claim and a list of sources saying
  what kind of place each is, its date and when it was read. Then every
  sentence is checked against its own source: citations to sources that do
  not exist are removed, and a claim with no source, a figure that is in
  none of its sources, or a sentence that shares almost no words with its
  source is marked and put to a fact checker that sees only the source's
  passage. Reports are kept, sealed, and download as Markdown. Check a
  text against its sources does the same for any text that cites [1],
  [2] … with web addresses or files. A fact-checker specialist joins the
  researcher. Research reads the web, so it is off while privacy keeps the
  machine to itself.
• Customer replies for a small business. A new Customers page, and the
  same in the chat ("answer this customer"). Replies are written only from
  the business's own answer book and the documents in its folder (prices,
  terms, hours; text, PDF, Word, OpenDocument, spreadsheets), in the
  customer's language, in a friendly or formal tone, with its signature.
  Each message is told apart (question, order, complaint, refund,
  cancellation) and each reply checked before the owner sees it: what the
  business's words do not answer is left as [[ASK: …]] for the owner, a
  promise of money or time nobody has made and a figure the business never
  gave are marked, and so is anything on the owner's "always leave to me"
  list. A reply is kept as a mail draft that waits for a yes like any
  other, and a draft with a gap still in it cannot be sent. A corrected
  reply can be saved in the answer book. A customer-care specialist writes
  drafts only.
• Tables, with every total checked. A new Tables page, and the same in
  the chat ("total my expenses by category"). A .csv, .tsv, .xlsx or .ods
  table is looked over first: each column's sum, range and average, cells
  that are not numbers (by row), rows entered twice, and every "Total" row
  compared with what its rows really add up to. Numbers are read however
  they are written (1 234,56 or 1,234.56, лв., €, %, a negative in
  brackets), each column deciding its decimal mark, and 1,250 is never
  guessed. A question becomes a recipe the model writes but never
  calculates; the program carries it out exactly — filters, a new column
  from a formula, groups, sums, averages, the largest first, a forecast by
  average or trend — leaves the sheet's own totals out so nothing counts
  twice, and checks every total a second way from the source rows. The
  result saves as a new workbook with its checks on a sheet of their own,
  never over an existing file. The finance and accounting specialists use
  it instead of adding up themselves. The .xlsx writer now writes several
  sheets, and .ods tables are read cell by cell.
• Invoices and VAT — information, not advice. A new Invoices & VAT page,
  and the same in the chat. An invoice register of sales and purchases,
  typed in, read from a PDF, Word file or scan, or imported from a table,
  every invoice checked as it is added: VAT exactly the rate of the net to
  the cent, the total the net and the VAT, a rate the country has, the basis
  for a zero rate, no VAT under reverse charge, the country's invoice
  number form, a plausible VAT number, no date in the future, no issued
  number twice, and gaps in the numbering shown. A month's VAT by rate, the
  amount to pay or deduct and its due date, and the year's sales against
  the registration threshold. Bulgaria's rules come from the VAT Act in
  force from 1 January 2026, each with its article, a link to the source and
  the date it was checked (20 % and 9 %, €51,130, the 14th of the next
  month, invoices within 5 days, ten-digit numbers); for another country
  the owner gives the rates and nothing is said about its law. Nothing is
  ever filed. The accountant specialist uses these tools.
• Filling in PDF forms. A new PDF forms page, and the same in the chat
  ("fill in this application"). A form's fields are read — text,
  checkboxes, radio buttons, lists, with their choices and whether they are
  required or read-only — and the form is filled into a new file beside the
  original, which is never changed and never written over. Every value is
  read back from the new file before it is saved, and a value a field
  cannot take is said while the rest is filled. Every filled value is drawn
  into the form so it shows the same in every reader: Helvetica for plain
  Latin text, otherwise a font from this computer that has the letters —
  Cyrillic included — embedded with only the letters used. Works with old
  and compressed (PDF 1.5+) files alike, and mends a damaged cross-reference
  table; encrypted and signed PDFs are left alone. No new library: the
  program reads and writes the PDF itself, as an incremental update.
