…df subpath Add a node-only `ksef-client-ts/pdf` subpath that renders FA(2)/FA(3) invoices and UPO(4.2)/(4.3) receipts to PDF from a template-driven block DSL, with pl/en/pl+en labels and automatic KSeF Code I QR whose hash is taken over the original input bytes. pdfmake is an optional peer (^0.2.20), lazily loaded, so the core install stays clean and `./pdf` imports never pull it in. Also adds the `ksef invoice pdf` CLI command, built-in templates for each supported version, i18n bundles, a verification harness (attw / publint / pdf-types / cold-subpath across the Node 18/20/22 matrix), a how-to guide, and the OpenSpec spec for the new invoice-pdf-render capability.

The invoice PDF renderer dropped bank account data entirely and emitted a QR verification URL with a NaN date: the payment due date and issue date were bound to the wrong XML paths, the payment-form code was left raw, and bank details were never modeled at all. - Add a bank-account repeater to the payment block (account number, SWIFT, bank name), rendered as localized label:value lines; skip empty optional payment fields. - Bind the payment due date to the payment-term element and decode the payment-form code to its name. - Read the QR issue date from Fa/P_1 (not the document root) and guard the verification-link service against an unparseable date instead of emitting a NaN segment. - Rebuild the FA(2)/FA(3) fixtures from a realistic payment structure so the strict self-consistency test exercises the payment/bank paths, and add tests for the QR date, the payment-form formatter, and bank-account rendering.

The release workflow triggers on tag push and does not depend on ci.yml, so a tag pointing at a commit that never went through PR CI could mint a published artifact without the guards that protect the public exports map: the ./pdf type check, the cold-subpath probe that proves ./pdf does not eagerly load pdfmake, and the attw/publint export checks. Extend the "Validate build" step in both publish-npm and publish-ghpkg to run the same guard set as ci.yml, keeping build first so the checks read the built dist. Both jobs run byte-identical command lists.

The PDF subcommand was written before main gained the completion-tree test that asserts COMMAND_TREE matches the subcommands each group actually registers, so rebasing the PDF work onto current main exposed the gap: `invoice pdf` was reachable but never suggested by completions.

`P_13_1` and `P_14_1` are the 23%/22% bucket alone, not the invoice total. Both default templates bound "Total net" and "Total VAT" to those single fields, so any invoice whose sales fall outside the standard rate printed blank or partial figures next to a correct "Amount due" — a visualization that misstates the invoice. A KSeF invoice carries no single net or VAT total, so a totals row now takes either one `path` or a `sum` of several, added in minor units so the decimals stay exact. The defaults aggregate the XSD bucket set: net over P_13_1..5 and P_13_7..11 (there is no P_13_6), VAT over P_14_1..5. The `P_14_*W` fields are excluded — they restate the same tax in PLN for foreign-currency invoices and would double-count. Sum paths are read non-strictly because a real invoice fills only the buckets that apply. Reproduced before the fix on an 8%-only FA(3): "Total net" and "Total VAT" rendered empty beside "Amount due: 540,00". After it they read 500,00 and 40,00; a mixed 23%/8%/exempt invoice adds up to 750,00 and 131,00. Full unit suite: 2477 passed.

A session UPO confirms a whole batch and carries one `<Dokument>` per accepted invoice — our own UPO parser has modelled that as an array all along. Both UPO templates, however, bound scalar paths like `Dokument.NumerFaktury`, and `getNode` follows the first element when a path crosses an array. A receipt for twenty invoices therefore rendered as a receipt for one, with nothing to indicate the rest had been dropped. The per-document fields now render through a `lines` repeater over `Dokument`, one table row per invoice, under a "Documents" heading. The session reference stays a scalar field above the table. Reproduced before the fix on a two-document receipt: the second invoice number was absent from the rendered tree. After it, a three-document receipt renders all three and a four-document one emits five table rows (header plus four). Full unit suite: 2484 passed.

The version guard only rejected a document it could positively identify as the wrong version. When the detector returned null it fell through and rendered anyway, binding every path against a root that does not exist — so a UPO, an FA(1), or arbitrary XML handed to an invoice template came back as a plausible, near-empty PDF instead of an error. Null is now a rejection. The detectors key off the root element plus a version marker the KSeF schemas make mandatory, so a null means "not this kind of document", not "cannot tell". The message distinguishes the two cases: an unrecognized input points at the input, a detected mismatch still names the version to use instead. Reproduced before the fix: rendering the UPO(4.3) fixture with `fa3-default` returned a 16547-byte PDF. It now throws, as do an invoice fed to a UPO template and arbitrary XML, while a detectable FA(2)/FA(3) mismatch keeps its original message. Full unit suite: 2489 passed.

The UPO branch was tested before the template branches, so once the input was a UPO — auto-detected or forced with --upo — both --template and --template-file were dropped on the floor. A custom UPO layout could never be selected from the command line, and a misspelled template name reported success instead of failing, because the flag was never read. An explicit template now takes precedence over auto-detection. The built-in registry holds the UPO layouts alongside the invoice ones, so the same branch serves both, and the renderer still rejects a template whose schema does not match the document. Reproduced against the built CLI: `--template totally-bogus-name` on a UPO wrote a 14978-byte PDF and exited 0. It now reports the unknown template, `--template upo-4_3` renders through the named layout, `--template fa3-default` on a UPO is rejected, and plain auto-detection still works. Full unit suite: 2492 passed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01H7pm4MqoegP7uMsX4hEg7Z
Strict mode throws on a missing scalar binding, which is what catches dot-path typos in the values a template prints. Presence tests and repeater sources are outside that net by design: `Platnosc` is minOccurs="0" in the FA schemas and `RachunekBankowy` is minOccurs="0" maxOccurs="100", so an absent node there is a cash-paid invoice, and making them throw would reject valid documents. That left a gap in our own presets — a misspelled `when` silently hides its block, a misspelled `from` silently yields a header-only table, and the strict-mode fixture test passes either way. This closes it where it can be closed without touching the public contract: every `when` and `from` path in every built-in template must resolve against that template's reference fixture. The scope of `strict` is now stated in the docs. Verified by mutation: misspelling `Fa.Platnosc` and `Fa.FaWiersz` in fa3-default each fails the lint, and both pass again once restored. Full unit suite: 2504 passed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01H7pm4MqoegP7uMsX4hEg7Z
Both table renderers sized every column `'*'`. pdfmake gives star columns one shared width and never shrinks it below the widest minimum content width among them, so a single long unbreakable token inflates all of them and the table silently extends past the page — the trailing columns are simply not on the paper. On a real FA(3) the "Wartość netto" column was cut off; the UPO receipt lost two of five columns. Columns now carry an optional `width` (points, `'auto'`, or `'*'`), and the invoice templates pin the narrow ones so the description column absorbs what is left. The UPO receipt cannot be fixed that way at all — a 35-character KSeF number beside a 44-character hash will not share a page-wide row — so a new `each` block repeats a group of blocks per collection entry with that entry as the binding root, and the UPO templates lay each confirmed document out as stacked label/value rows separated by a divider. This also repairs a regression from the multi-document UPO fix: that change traded "silently drops every document after the first" for "renders them all but clips the columns". Verified by rendering real invoices and receipts: the FA(3) line table now shows all seven columns in Polish and in the wider pl+en labels, and a five-document session UPO renders every field of every document on the page. The built-in template lint learned `each`, so a typo in its `from` is caught too. Full suites: 2506 unit, 119 E2E.

The KSeF number sat on its own full-width row below the header, in the small muted style, so the one identifier a reader looks up first was the least prominent thing on the page and visually detached from the invoice number and issue date it belongs with. The header block now takes a `ksefNumber` binding and stacks it under those two, right-aligned in the body font — three `label: value` lines that read as one group. The row it replaces is gone from both invoice templates. An absent number drops the line entirely rather than printing a dangling label; the OFFLINE marker already covers that case. Verified by rendering a real FA(3) in Polish, English and pl+en, and the same invoice with no KSeF number. Full suites: 2508 unit, 119 E2E.

Rendering real invoices exposed several ways the default templates lost or misplaced information, and the DSL had no vocabulary to fix them: - A counterparty established outside Poland carries NrVatUE or NrID rather than a NIP, and the buyer panel was bound to NIP alone — so a foreign buyer's identifier was replaced by a blank line. Party fields can now list alternatives and print the first that resolves, and a line that resolves empty is dropped instead of leaving a gap. - The address and contact details had no headings, and the contact block — which KSeF allows up to three times per party — could only ever show its first entry. Party fields can now be a labelled group, repeating over a collection when it names one. The country code joins the address. - `height: 6` on a spacer cost about 17pt: the block emitted an empty text node, which still occupies a full line. It is now an empty canvas and adds exactly what it says. Existing spacers were rescaled so only the gap above the parties panel changes; that one is halved. - The KSeF number sat below the header in the small muted style; it now stacks with the invoice number and issue date it belongs with. Alongside: a logo can be passed from the command line (the library still takes only a data URI, so the renderer never touches the filesystem), the header sizes it, and `en+pl` joins `pl+en` as a bilingual locale — the order is read from the locale name instead of being hardcoded. A new E2E spec renders twelve variants through the built CLI and keeps them for review, mirroring the throwaway script this work was iterated with. It asserts only that each PDF is written and structurally complete; layout is judged by eye, and asserting on positions would break on every deliberate design change. Its fixtures are new and fully anonymous — a cross-border np I invoice, a mixed 23/8/exempt one, a buyer with no identifier, and a generated logo. Full suites: 2531 unit, 134 E2E, plus the ./pdf type and cold-subpath guards.

Spec 35 drives the renderer through the CLI, but the CLI is a strict subset of the library: it wires five of the ten RenderOptions and has no way to pass a template as an object. Everything else — baseQrUrl, theme, bilingualSeparator, strict, invoiceHash, renderInvoicePdfFromTemplate — had no end-to-end coverage at all, so a regression there would have been invisible simply because no flag exposes it. The spec imports by package specifier, which resolves through the exports map to dist/, so it exercises the published artifact rather than src; a guard asserts that. Assertions stay as shallow as in spec 35 — a complete PDF is written and kept for review — with the rejection paths checked for an error instead of a blank page. One option turned out to be inert: no built-in template consumes `theme.accent`, and DSL styles are static values, so an accent cannot colour anything today — it reaches a template only as the `opts.accent` string binding. The test renders through a template that actually reads that binding, so the option is exercised rather than silently ignored. E2E suite: 150 tests.

…efix The two specs wrote to different places and numbered their outputs independently, so reviewing a run meant looking in two directories and mentally mapping `L4` to what it exercised. Both now render into `.pdf-preview` with a `cli-`/`lib-` prefix and a number that sorts the way the set reads: invoices first, receipts last, since a receipt is a different document. Generated inputs — the single-bucket template, the five-document receipt, the throwaway custom template — move to an `_inputs` subdirectory; they are inputs, not results, and no longer sit among the pages being reviewed. Sharing a directory means neither spec may clear it: they run in parallel, and whichever started second would delete the other's output. Each now removes only files carrying its own prefix. Verified by running them together three times and alone, with all 21 pages present each time.

A KSeF invoice states no net or VAT total. Net sales are split across the `P_13_*` rate buckets and the tax across `P_14_*`; the only total in the document is `P_15`, the amount due. The template printed a single computed net and VAT figure and labelled them like any other field, so two of the three numbers under the line items were the renderer's arithmetic, visually indistinguishable from the one read straight from the XML. On an invoice whose buckets do not reconcile, that is the renderer putting words in the issuer's mouth. `totals` now picks what appears above the amount due, which is always shown: `none`, `buckets` (a row per bucket the invoice carries, every figure a direct field reading), `summary` (the computed totals) or `both`. The default is `buckets` — always correct, never duplicated, and nothing on the page that the document does not say. It works through row-level `when` on the totals block and two context flags, the same mechanism that already governs the QR and the OFFLINE marker, so the template keeps control of layout and a custom one can regroup freely. Rows that resolve empty are skipped, which is what lets a template list all eighteen buckets and print only the two or three in use. Two consequences worth naming. Strict mode can no longer police this block: with every bucket listed, most rows are legitimately absent, so all totals reads are lenient — the built-in template lint now requires the amount due and at least one bucket to resolve instead. And the zero-rated buckets were missing from the sum entirely: `P_13_6_1/2/3` (domestic, intra-EU supply, export) are separate fields, not a `P_13_6`, so an exporter's net total was understated until now.

`strict` is meant to turn a dot-path typo into an error instead of a blank line. It could not do that job: the built-in templates bind fields the FA schema declares optional, so the first one an invoice happened not to carry threw. An unpaid invoice has no `Zaplacono`; a line may omit `P_7`; a rate bucket is present only if that rate was used. Enabling strict on a real document was therefore an error, and the previous commit gave up on the totals block entirely — reading even `Fa.P_15` leniently. A binding is now policed unless the template marks it `optional`, and the built-in templates mark exactly the paths the schema allows to be absent — 31 of them, verified against the XSD ancestry rather than guessed. `Fa.P_15` is not among them: it has no optional ancestor, an invoice always states its amount due, so a misspelled `totalDue` path throws again. That was the one binding worth policing most, and it is back. The marker generalizes across the blocks that read bindings — lines, table, payment, parties, totals — so a custom template gets the same contract: say what may be missing, and strict guards the rest. Verified by rendering every fixture strict, including an unpaid invoice and one without the optional second address line, and by misspelling the amount due, a party name and a line column in turn — each throws with the offending path. The trade-off is pinned too: a typo inside a path marked optional is not caught, and a test says so. Full suites: 2559 unit, 153 E2E.

…oter
Two layout changes and one that is not really layout.
Dividers now bracket the payment section, so bank details read as their own
block rather than trailing off the totals.
The `ksef-client-ts` note moved out of the content flow into a running page
footer: the localized attribution on the left, a `Page 1 of 3` indicator on
the right, aligned with the page margins and repeated on every page. It has
to be a pdfmake callback rather than a block — only pdfmake knows the page
total, and only after the content is laid out. The indicator keeps the body
colour instead of the muted credit grey; it is information a reader looks
for, not a byline.
The page indicator is a single label carrying its own `{page}`/`{pages}`
placeholders rather than a phrase assembled from parts, so a bilingual
render reads "Page 1 of 2 / Strona 1 z 2" instead of interleaving the two
grammars into "Strona / Page 1 z / of 2". The `page` and `of` keys it
replaces had sat in both bundles unused.
The attribution itself is fixed in the renderer and no longer a template
field: a template may restyle the footer or leave it out, but the schema
rejects a credit of its own.
Full suites: 2573 unit, 153 E2E.

…marker `partyAddress` styled the contact block as well as the address, so it is renamed `partyDetails`. The identity lines it never covered — the counterparty's name and tax number — had no style to reach for at all, because a panel could only style a labelled group, never its own lines. A party column now takes a `style` that its groups inherit unless they declare one, so the built-in templates set `partyIdentity` up top and let the address and contact groups drop to the smaller `partyDetails`. The group style is passed down instead of being stamped onto the rendered nodes afterwards, which also stops a nested group's sub-heading from losing its heading style. The OFFLINE marker moves into the KSeF number's slot in the header, via `offlineStyle`, rather than sitting full-width under the title — the condition is unchanged, only the position. A new lint fails a built-in template that references an undefined style: pdfmake ignores an unknown style name silently, so a missed reference in a rename costs a font and no test. A second one checks the two names the renderers reach for without the template naming them, `title` and `h2`. Verified: unit 2588, e2e 153, tsc, markdownlint, build.
A visualization carried Code I and nothing else. Code II — the link that verifies the issuer of an invoice written offline — is now printed beside it, and both take a clickable link when asked. Code II is supplied rather than derived: its URL is signed with the private key of a KSeF offline certificate, which a PDF renderer has no business holding. The codes are encoded here and handed to pdfmake as SVG instead of going through its QR node. That node sizes a code at whole points per module, so a code existed at only a handful of sizes and `fit` was a ceiling rather than a measurement — two codes of different data lengths could not be made to match at all, and a `fit` under the module count silently rendered nothing. Drawing the modules ourselves makes the size exact, so equal `fit` means equal footprint whatever each code carries, and brings the quiet zone the standard requires and that node omits. Error correction goes from the 7% default to 15%, the level KSeF's own reference clients use: an invoice gets folded. Both codes sit under a heading, in a row that holds them against the right margin however wide the heading runs. An absent code drops its column rather than emitting an empty node, which would have claimed an elastic column and pushed its neighbour off the margin. Sizing is the thing no render test can see — an unreadable code is still a valid PDF — so it has its own spec, measuring the built-in templates against real Code I and Code II URLs of both signature kinds. Verified: unit 2620, e2e 161, tsc, markdownlint, build.
Ukrainian joins Polish and English, and the bilingual locales stop being a hand-kept list of pairs: a locale's halves are read from its own name, so all six orderings work and the next language needs only its bundle. Two things stay Polish in every locale — the VAT rates and the payment forms, which decode from a Polish fiscal enum the official visualizations print untranslated. A missing translation does not fail a render, it falls back to Polish and a Ukrainian invoice quietly grows Polish headings, so the bundles now have to stay key-complete. The preview set had grown to 34 PDFs, one per feature, with the same document rendered over and over for one flag at a time. It is now 18: a covering design where each row varies several dimensions at once and every value of every dimension still appears. The totals modes are deliberately exempt — they only mean anything compared side by side. Two checks keep the design honest: the CLI set reads its own rows back and fails if a dimension loses its last cover, and the library set reads the option list off the published types, so a new render option fails until something exercises it. The QR row's right-margin layout moves out of the preview set and into a unit test, where it belongs — it is a property, not a picture. The link under each code now lines up with the code's first module rather than with the quiet zone around it. Verified: unit 2638, e2e 149, tsc, markdownlint, build.
A block's heading is the block's own, not the template's, so the renderer reached for a style name by convention: `h2`, hardcoded, invisible in the template JSON. A template could redefine what `h2` looked like but could not say which style its section headings should take, and a template that omitted `h2` lost every heading silently. `headingStyle` names it per block, and it reaches only the first line the block prints. The labels nested inside — the address and contact groups, the bank-account heading — sit a level down and stay on `h2`, so lifting section headings does not drag every label in the document along. The built-in templates now name both levels explicitly and set them apart: `h1` for the section headings, `h2` for what sits under them. Two gaps in the style lint closed on the way. It matched the key `style` exactly, so `linkStyle` and `offlineStyle` were never checked and a typo in either silently dropped the style. It now takes any key ending in `Style`. And it demands both heading levels exist, not just the one a block happens to name. Verified: unit 2644, e2e 149, tsc, markdownlint, build.
Some of what belongs on an invoice is not in the invoice — delivery terms, a payment reminder, a line the accountant wants on every document. There was nowhere to put it: a template binds to the XML, and the XML is what KSeF holds. `notes` takes those as a list of heading-and-body sections and prints them where the template puts its `notes` block, between the payment details and the verification codes in the built-in ones. Both halves are plain text, so a note can neither reach into the document nor disturb the layout around it. An entry blank on both halves is dropped, one with only a head or only a body prints that half, and a render supplying none leaves no trace of the block at all — the block renders nothing rather than an empty gap, so a template carries it unconditionally. The rule that closes the section had to become conditional with it, so a `divider` now takes a `when`. Without that an invoice carrying no notes showed a line hanging over its verification codes. From the command line the sections come from a JSON file, whose shape is checked when it is read: a hand-written file is where a shape mistake happens, and printing nothing at all is worse than failing with a reason. Verified: unit 2667, e2e 149, tsc, markdownlint, build.
The default templates are deliberately plain, which leaves the question of what a template can actually reach unanswered — and answered wrongly by assumption. `fa3-showcase` renders the same FA(3) invoice in a full palette, with letter-spaced headings, highlighted text, its own label wording, and full-width colour bars drawn as data-URI images, since the DSL has no drawing primitive of its own. It is as useful for its omissions. The line-item table's header fill and the rule colours belong to the renderer, not to a template, and Roboto is the only bundled font — so a design asking for any of those needs a code change, not a template. Registered like any other built-in rather than parked in an examples folder, which puts it under the lints the others answer to: every `when` and repeater path resolving against a fixture, every style it names being defined, both heading levels present. A render smoke test and a preview row cover what a lint cannot — that the shape still produces a page. The preview row also closes a dimension the grid never had: selecting a built-in by name. Every row until now took the auto-detected template or a file. Verified: unit 2673, e2e 150, tsc, markdownlint, build.

- Around line 47-48: Update detectInvoiceVersion so kodSystemowy and
WariantFormularza must identify the same FA version, rejecting contradictory or
structurally invalid markers; update detectUpoVersion to extract the version
only from the Potwierdzenie root namespace declaration, not arbitrary text
content. Add rejection tests covering conflicting FA markers and a non-KSeF
Potwierdzenie containing the marker text.

- Around line 30-33: Update both table renderers in table.ts and totals.ts so
they return null when the constructed body has no rows (body.length === 0),
before producing the pdfmake table. Add regression tests covering a headerless
repeater and empty totals, ensuring non-empty bodies retain the existing
rendering behavior.

- Line 16: Update buildInvoiceVerificationUrl and its date validation to reject
date-only issueDate values whose canonical UTC YYYY-MM-DD representation differs

pdfmake assembles the document asynchronously, so a failure raised in that phase — an image it cannot decode, a font it cannot load — landed long after createPdfBuffer's `try` had returned. `getBuffer`'s callback has no error channel, so nothing settled the promise: the rejection escaped to the process and Node terminated with ERR_UNHANDLED_REJECTION and a raw stack trace, where the caller should have seen a KSeFPdfError. Drain the document stream instead. Its `error` event is where pdfmake reports these failures, and it carries a plain string, so anything that is not an Error is wrapped. Verified against pdfmake 0.2.23 with a valid 1x1 GIF as the logo — a format pdfmake refuses. Before: exit 1, ERR_UNHANDLED_REJECTION. After: the promise rejects with "Invalid image: Unknown image format." Regression tests cover the stream's three outcomes and the end-to-end render. Full unit (2678) and E2E (150) suites pass. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`--logo` advertised PNG, JPEG, GIF, WebP and SVG, but pdfmake's `image`
node draws only PNG and JPEG. The other three were read, base64-encoded
and handed to the renderer, which then failed with "Unknown image
format" partway through — so `ksef invoice pdf --logo brand.svg`, spelled
exactly as the flag's own help suggested, never produced a PDF.
Accept only what renders, and say so in the flag description and in the
`logo` option's docs.
Verified against the built CLI with pdfmake 0.2.23:
--logo logo.svg -> exit 1, "Unsupported logo format \".svg\".
Supported: .png, .jpg, .jpeg" (no file written)
--logo logo.png -> PDF written, 22861 bytes
Before the change the same SVG reached the renderer and died there.
Full unit (2678) and E2E (151) suites pass.

Every built-in invoice layout printed monetary values bare and bound Fa.KodWaluty nowhere, so an invoice settled in EUR or USD rendered identically to one settled in złoty. A reader has no way to tell them apart, and the default assumption on a Polish invoice is the wrong one. Add the currency as the closing totals row in fa2-default, fa3-default and fa3-showcase, with a label in all three bundles. KodWaluty is mandatory in both FA(2) and FA(3), so the row never resolves empty and needs no optional marker. Verified on the EUR fixture (e2e-buyer-no-id.xml): the totals now close with "Currency EUR" where they previously ended at the amount due. The existing totals-mode assertions were updated for the extra row, and new ones pin the currency across all four modes and all three built-ins. Full unit (2680) and E2E (151) suites pass.

The money and number formatters parsed their input with `Number` before
formatting it. TKwotowy allows 18 digits, well past what a double holds
exactly, so a schema-valid amount was rewritten on the way to the page:
9999999999999999.99 printed as 10 000 000 000 000 000,00. The same round
trip undid the decimal-safe totals summation, which had gone to some
trouble to keep those digits.
Format the decimal string directly instead, reusing the shape sumDecimal
already parses. A third decimal now rounds half away from zero rather
than inheriting whatever binary rounding produced, and a value that
rounds to nothing no longer prints a minus sign.
Verified with the values from the review:
before formatMoney('9999999999999999.99') -> 10 000 000 000 000 000,00
after formatMoney('9999999999999999.99') -> 9 999 999 999 999 999,99
before formatMoney('0.145') -> 0,14 after -> 0,15
Every existing formatter assertion is unchanged. Full unit (2688) and
E2E (151) suites pass.

… from The set had grown to thirteen renders, and five of them said the same thing: rows 06–09 varied only --totals on one document, and rows 01–05 already spend all four modes between them. Row 10 then paired with 08 to show summed totals against single-bucket ones — a comparison whose arithmetic is pinned exactly in totals-sum.test.ts, while this suite only ever asserts that a complete PDF appeared. So the four mode pages are gone, and the template-file render moved onto the flags row 05 already carried. That row is now the one page drawn from a template file, which is what keeps --template-file wired, and its name says so; a comment records that its totals read one bucket by design, so the narrower net and VAT lines read as the template choosing rather than the renderer erring. Thirteen pages down to eight, with every dimension of the covering grid still spent and its assertions untouched. Also drops the two references to invoices/temp/regen.sh: that script is outside the repository, so a comment here claiming the two mirror each other is a promise this file cannot keep. Verified: spec 35 renders all eight variants, unit 2734, E2E 151. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Per CodeRabbit PR review on #46: narrowing the scan to a tag named Potwierdzenie was not narrow enough. The match was by name, so a commented-out root before the real one decided the version — a comment carrying KSeF/v4-2 ahead of a v4-3 root made the renderer pick the wrong UPO template. Reproduced with exactly that document. Strip comments and anchor the match to the first element in the source, whatever it is named, then require that element to be Potwierdzenie. The bot's own suggestion — read the namespace off `parsed.Potwierdzenie` — cannot work here: the parser runs with `removeNSPrefix`, which drops xmlns declarations entirely, so a parsed UPO root is `{"X":"1"}` with no version anywhere on it. That is why this reads the source at all, and the comment now says so. Co-Authored-By: Claude Code <noreply@anthropic.com>
Per CodeRabbit PR review on #46: the exported DSL type still promised that NotesBlock.headingStyle applies to each note's heading. It stopped doing that in 9f7b830, which gave the section a heading of its own and put the notes a level below it — headingStyle styles the section, and a note's title is a fixed h2. The code is the intent here, so the contract is what needed correcting. The prose in pdf-export.md already described it correctly; its list of blocks carrying the option was missing `notes`, which it now names. Co-Authored-By: Claude Code <noreply@anthropic.com>
Per CodeRabbit PR review on #46: the calendar check only looked at bare `YYYY-MM-DD` strings, so "2026-02-30T00:00:00Z" walked past it and was read as 2026-03-02 — the same defect the check was added for, wearing a timestamp. The written calendar fields are now checked on their own terms, for a bare date and a timestamp alike. Deliberately not the bot's suggestion of comparing the written prefix against the parsed UTC date: with an offset the two legitimately differ, so that test refuses real dates — "2026-01-01T00:30:00+01:00" is 2025-12-31 in UTC and is a perfectly good issue date. Both of those now have a test proving they still pass. Co-Authored-By: Claude Code <noreply@anthropic.com>
Per Codex review of version/v0.12.0 against main: an advance invoice (`RodzajFaktury` `ZAL` or `KOR_ZAL`) may carry no `Fa.FaWiersz` at all — the goods and services it covers are recorded under `Fa.Zamowienie`, which both default templates ignored. Rendering one produced a line-item table holding nothing but its header row and dropped the document's actual content, so the only figures on the page were the totals. A `lines` repeater now takes `when`, as almost every other block already does, and the two default templates use it twice: the item table disappears on a document that has no items, and an order table appears under its own heading when the document has one, with the order value beside the rate buckets. New pl/en/uk labels name both. The template lint now reads each built-in against a *set* of fixtures rather than one, because no single document exercises both branches; a misspelled path still resolves against none of them, so it stays a lint. Reproduced against the interpreted document definition: the advance invoice rendered one table whose body was `[header]` and no order rows. Afterwards it renders the order rows, no header-only table, and the ordinary fixtures are untouched — verified on the page as well as in the tree, via the new preview page. Full unit and e2e suites pass. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Per Codex review of version/v0.12.0 against main: `--env` was cast to the
three environments rather than checked against them, and the host lookup
treats anything it does not recognize as production. So `--env staging`,
or any typo, printed a production verification code on a test invoice and
the command reported success — the one way the page can be wrong that a
reader cannot see, because nothing on it names the registry.
Validate the flag where `--locale` and `--totals` are already validated.
Reproduced through the command with `--env staging`: the render options
came out `{…,"env":"staging"}` and the file was written. Now the command
exits non-zero naming the three valid values and writes nothing, checked
both at the seam and through the built CLI.

Per Codex review of version/v0.12.0 against main: a divider was a canvas line of a constant 515pt — portrait A4 with 40pt margins, and nothing else. A canvas needs its length in points and the interpreter has no page to measure, but the DSL lets a template choose its size, its orientation and its margins, so the constant was wrong everywhere else: measured out of the PDF, the old rule fell 247pt short on landscape A4 and hung 175pt past the margin on A5. Draw it as a single-cell table sized `'*'` with a border on the cell's bottom edge instead. pdfmake measures that against the page it is drawn on, and an empty canvas in the cell keeps the height at zero, so 300 rules still fit on one page — the property the canvas was chosen for. The new test reads the stroke back out of an uncompressed PDF and checks it against four geometries; against the previous renderer all four fail, including portrait A4, which was short by the 0.28pt the constant had rounded away. Full unit and e2e suites pass, and the preview pages are unchanged apart from rules now ending flush with the right margin. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The built-in templates printed `Fa.P_15` under a flat `Do zapłaty`, but the FA schemas give that field three readings. On an advance invoice (`ZAL`/`KOR_ZAL`) it is the payment the document records as already received, so the PDF told the reader to pay it a second time. And when the document carries `Fa.Rozliczenie.DoZaplaty` — P_15 plus surcharges minus deductions — that is the figure actually owed, so the page named a number nobody should pay. The reading is derived once from `Fa.RodzajFaktury` and the presence of the settlement, and the templates list one row per reading plus the settled payable when the document states one. Payment rows take `when` for the same reason totals rows do. Verified with a new fixture pair carrying `Rozliczenie` and a test that renders all three built-ins against an ordinary, an advance and a settled invoice: before, the advance invoice printed `Do zapłaty: 615,00` and the settled one printed `Do zapłaty: 615,00` instead of the 625,00 it owes; now the first says `Kwota zapłaty` and the second prints 625,00 under `Do zapłaty`. Full suite green: 2771 unit + 153 e2e. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`TPodmiot2` states the counterparty identifier as a choice, and two of its branches are pairs: `KodUE` is mandatory alongside `NrVatUE`, and `NrID` may be qualified by `KodKraju`. The templates bound only the number, so an EU buyer's VAT number lost the country prefix that makes it that country's number, and a foreign identifier lost the country it was issued in. A `firstOf` alternative can now name the qualifier the schema pairs it with. The qualifier is read leniently and dropped when absent, so an unqualified `NrID` — which the schema allows — still prints on its own. Verified by rendering the buyer panel of all three built-ins with each branch of the choice swapped into the fixture: `DE 123456789` and `UA ID-999` now print whole, where before the page showed `123456789` and `ID-999`. A bare `NrID` and a domestic `NIP` are unchanged. Full suite green: 2783 unit + 153 e2e. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`Podmiot2.DaneIdentyfikacyjne.Nazwa` sits in an optional sequence in `TPodmiot2` — art. 106e ust. 5 pkt 3 lets an invoice leave the buyer unnamed — but the templates bound it unmarked, so `strict` policed it. A schema-valid document therefore failed to render with `Missing binding`, which is exactly the outcome the mode's rule exists to prevent: mark what the schema declares optional, police the rest. Verified by stripping `<Nazwa>` from the FA(3) fixture and rendering strict: before, `Missing binding: "Podmiot2.DaneIdentyfikacyjne.Nazwa"`; now a PDF. A second test pins the marker in all three built-ins. Full suite green: 2787 unit + 153 e2e. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`Podmiot2.Adres` is minOccurs="0" — art. 106e ust. 5 pkt 3 lets an invoice omit the buyer's address — while `AdresL1` and `KodKraju` are mandatory only within an address that exists. The templates bound the children directly, so a strict render of a schema-valid document without a buyer address failed with `Missing binding: "Podmiot2.Adres.AdresL1"`. The group now reads `from` the optional parent, the way the equally optional `DaneKontaktowe` group already did, and disappears heading and all when the document carries no address. The seller's address stays bound directly, since FA declares that one mandatory. Verified by rendering the buyer panel of all three built-ins with and without `<Adres>`: the address still prints in full, an invoice without one now renders (strict included) and drops only that group while the seller's address stays, and removing the seller's address still throws.

`TerminPlatnosci` is maxOccurs="100" — an invoice paid in instalments states a term per instalment — but the templates read it through a scalar path, and a path walk that meets an array follows its head. Every date after the first vanished from the page with nothing to show it had ever been there. A payment row can now repeat over a collection, printing one line per entry with the entry as its binding root, which is what the bank-account section already did a level down. Verified against the FA(3) fixture given a three-date schedule: before, one date; now all three, in order. A single-term invoice prints exactly what it did, an invoice with no terms prints no term line, and a term stated only as a description is skipped rather than printing an empty label.

The version regexes matched anywhere in the root start tag, so any document with a `Potwierdzenie` root that merely quoted `KSeF/v4-3` — in a note, a source URL, or a second namespace it does not use — was detected as a UPO and routed to the UPO renderer instead of being rejected. Detection now takes the declaration bound to the root element's own prefix (`xmlns` when it has none) and reads the marker from that value alone. Verified: `<Potwierdzenie data-note="KSeF/v4-3">` returned `UPO(4.3)` before and returns null now, as does a root bound to an unrelated namespace while declaring the UPO one under a prefix. A prefixed root still resolves through its own declaration rather than a sibling's, and the real fixtures are unchanged. Full suite green: 2817 unit + 153 e2e.

`Fa.Platnosc` states how much has been paid through a choice: either `Zaplacono` — a bare 1 meaning settled in full, with `DataZaplaty` — or `ZnacznikZaplatyCzesciowej` (1 in part, 2 in full) with up to 100 `ZaplataCzesciowa` entries, each an amount, a date and a form. The templates bound only the first branch, so an invoice paid in instalments printed nothing at all about its payments: not that part of the money had arrived, not how much, not when. Neither branch's `DataZaplaty` was printed either. The payment block's one-off `accounts` section becomes a list of repeating groups, because the part payments need the same shape — several fields per entry, kept together — and one repeating row per field would have split them into three parallel lists. A group's paths are entry-relative, with a leading `/` to reach the document root, which is how a part payment keeps the currency the invoice states once. The paid/part-paid status is a flag-gated label rather than a printed value: the schema's `1` tells a reader nothing the label does not. Verified against a new fixture pair taking the partial branch, and by eye on the rendered page — the preview set gains cli-10-invoice-partial-payments. Full suite green: 2839 unit + 154 e2e. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
An invoice PDF has to say what a reader owes, and the FA schemas make that harder than it looks: `P_15` means four different things depending on the document, and the money that has already changed hands lives in three unrelated elements. The built-in templates knew about none of it, so whole classes of document printed a figure that was wrong, absent, or unexplained. What the pages now cover: - Payments received by an advance invoice (`Fa.ZaliczkaCzesciowa`), which add up to `P_15` exactly, and the advance invoices a settlement is issued against (`Fa.FakturaZaliczkowa`, numbers only — no amount lives there). - Settlements against the receivable (`Fa.Platnosc.ZaplataCzesciowa`), which do not add up while the invoice is only part-paid, plus a paid/part-paid status that reads as a fact rather than as the schema's `1`. - A settlement invoice in both of the shapes the schema allows: the remainder stated in `P_15`, or `P_15` as the whole amount with the remainder defined as the difference from the payments received. Nothing carries that difference, so it is computed. - An overpayment (`Fa.Rozliczenie.DoRozliczenia`), where the page must not ask for money at all. Two DSL additions carry the computed figures: `sumFrom` takes the sum of one binding over a repeater, and `less` subtracts such a sum. Both yield blank rather than a wrong number when anything they read is unparseable. The payment block's one-off bank-account section became a list of repeating groups, since the part payments need the same shape, and a group may reach the document root with a leading `/` so an amount inside a repeater keeps its currency. The preview set is reorganized around two independent two-document chains — different buyers, amounts, invoice numbers and forward-moving dates — so one deal can be followed from page to page, with the standalone cases after them. Verified by eye on all fourteen rendered pages as well as by test. Full suite green: 2864 unit + 158 e2e. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The settlement fixtures carried the full order in `P_13_1`/`P_14_1` while `P_15` held only the remainder, so the page said 500,00 net plus 115,00 VAT and then asked for 165,00 — figures that cannot all be true of one document. Worse, the advance invoice had already declared the tax on its own share: taxing the whole order again on the settlement would put 199,15 of VAT on a deal that carries 115,00. The tax summary now covers what is left, which is the share the advance did not: 134,15 net and 30,85 VAT against a stated `P_15` of 165,00. The line items still state the whole order, as the schema requires. Chain B is rebuilt the same way, and it no longer restates payments its own advance invoice had already invoiced — it documents one further payment of its own, so `P_15` covers that payment plus the rest and the remainder is the difference the schema defines. Each document now reconciles internally, and the tax declared across a chain adds up to the tax on the deal: 84,15 + 30,85 = 115,00, and 149,59 + 80,41 = 230,00. Alongside it, two things the pages were leaving to the reader to work out: a document now heads itself `Faktura zaliczkowa` or `Faktura rozliczająca` when it is one — a correction of an advance invoice is not one, and stays plain — and the order total says `brutto`, so it is not read as a net figure beside the net buckets under it. Verified on the rendered pages as well as by test: every money column now sums to the figure below it. Full suite green: 2873 unit + 158 e2e. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A settlement invoice states the whole order in its line items but taxes only what is left, so the page shows 500,00 of line values above a demand for 165,00 with nothing to connect them. The bridge is now printed: the order's net, and what the advances covered. Both are derived, so they appear only under `totals: 'summary'` or `'both'` — `'buckets'` promises that every number on the page traces to a field, and this keeps that promise. Neither figure invents tax: the order's net is a sum of stated line values and the advances' share is that sum less the stated remainder. It stops at net deliberately, because a settlement invoice carries no VAT or gross figure for the whole order at all — `Fa.Zamowienie` belongs to advance invoices, and `P_11Vat` is a special case rather than a per-line tax — so stating those would mean re-deriving tax from the rate and risking a figure the issuer never declared. The arithmetic closes against the other end of the chain: on the second chain the bridge computes 650,41, which is exactly the net its advance invoice declared. Also here, two smaller things: a computed figure may now be a single binding or a fixed list as well as a sum over a collection, which is what lets the bridge subtract a multi-rate remainder; and a caller may reword any label for one render, outranking both the template and the bundle, so an issuer who says "faktura końcowa" need fork neither. Full suite green: 2884 unit + 158 e2e. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The preview set had no advance or settlement page in anything but Polish, so every label this story added — the document titles, the payments received, the order-to-remainder bridge — was only ever seen in one language. Chain B now renders with `--locale en`, which puts each of them on a page in English without adding a page. The document data stays Polish, as it must: a locale switches labels, not the invoice.

Per CodeRabbit PR review on #46: the root-element match refused `<?` and `<!` at the opening bracket only, so a processing instruction quoting a start tag — legal XML, its content runs to `?>` rather than to the next `>` — had that fake tag matched instead of the real root, and its namespace decided the version while the parsed object's `Potwierdzenie` root passed the check unchanged. The same pattern ended the tag at the first `>`, which XML allows unescaped inside an attribute value, truncating the tag and losing an `xmlns` declared after it. The prolog is now skipped node by node, each to its own terminator, and a start tag ends at the first `>` outside quotes. Co-Authored-By: Claude Code <noreply@anthropic.com>
Per CodeRabbit PR review on #46: `RepeatedSum` declared all three of its fields optional, so `{}` and `{ from: 'X' }` type-checked while the schema that validates them refuses both — a caller building a template as an object learned about it at render time rather than at compile time. A union of the two real shapes says the same thing the two refinements do. The runtime rules had no tests of their own, so they get some: the three shapes that are accepted, and the three that are not. Co-Authored-By: Claude Code <noreply@anthropic.com>
Per CodeRabbit PR review on #46: nothing stopped a payment row carrying both `sumFrom` and `path`. The renderer settles the computed case first and returns, so the binding was silently dropped and the sum printed under a label written for the reading — a wrong figure with no error behind it. `from` and `less` are discarded the same way. The sibling `totals` row has carried this refinement all along; the payment row now does too. Not reapplying `.strict()` after `.extend()`, which the review also asked for: the pinned zod 4.4.3 does preserve the unknown-key behaviour of a strict object across `.extend()`, verified against the installed version.

The validator already refused a payment row that is both read and computed. The type did not, so a template built as an object compiled with `sumFrom` beside `path`, `from` or `less` — and the renderer settles the computed figure first, so such a page prints it under a label written for the reading. The row is now a union whose computed branch forbids the reading properties, pinned by negative compile assertions in the published-types fixture, which checks the built declarations rather than the source. The preview set takes back its stray page: the one-sided notes render joins the numbered table as 12, with the pages after it shifting up, instead of writing an unnumbered PDF beside them — and it now asserts the file exists, as every other page does. Both PDF specs also name the TEST verification host rather than DEMO. Neither spec touches the network, but a page should not name one environment while the specs beside it authenticate against another. CLAUDE.md becomes AGENTS.md, reworded for any coding agent, with CLAUDE.md and GEMINI.md pointing at it and the two references in the repository repointed. It also gains a short note on which environment the E2E specs drive.

`Rozliczenie.DoZaplaty` is, in the schema's words, the amount due "równa polu P_15 powiększonemu o Obciazenia i pomniejszonemu o Odliczenia". Where a document states it, that is what the reader owes — but the remainder row subtracted the instalments from `P_15` regardless, so an invoice carrying a surcharge and settled in part printed a remainder short by that surcharge, directly under its own correct `Do zapłaty` line. Two figures on one page that cannot both be right, and nothing to raise an error: both readings are valid shapes on their own. Nothing in FA stops the two from meeting, so the base is now chosen per document: a new pair of payment flags says whether the instalments come off the stated payable or off `P_15`, and each of the three invoice templates lists one remainder row per base, in totals and in payment alike. Verified with a case built from the part-payment fixture plus a 10,00 surcharge (P_15 615,00, payable 625,00, 450,00 paid): before, both blocks printed 165,00 in all three templates; after, they print 175,00, while an invoice with no `Rozliczenie` still reads 165,00 off `P_15`. Full unit suite 2905 passing, and the two PDF E2E specs 39 passing against a fresh build.

…ints The package ships a bundle per entry point, so a render from `./pdf` threw an error built from that bundle's own copy of the error classes. `instanceof KSeFError` against the root entry was therefore false, and `./pdf` exported no constructor of its own — leaving a consumer of the PDF module with no typed way to catch anything, while the documentation promised that one `instanceof KSeFError` covers every error the library throws. The base class now recognises its own kind by a registered symbol, so it answers for an error from any entry point. Subclasses keep the ordinary prototype test, so one kind of failure is still told apart from another; `./pdf` exports the two classes it throws for exactly that, and the documented contract now says which check is which. Verified against the built package in both module systems: before, an invalid template rejected with `instanceof KSeFError` false under ESM and CJS alike; after, true in both, with the subclass checks still distinguishing a bad template from a missing pdfmake. Pinned in tests/package, which runs against the built artefact in CI. Unit 2905 passing, package 28, PDF E2E 39, and both published-type checks clean.

Adds PDF rendering to the client: KSeF invoices and their official UPO receipts to print-ready documents, entirely offline, from a declarative template DSL.
pdfmakeis an optional peer loaded lazily, so installing the library pulls in nothing new until PDF output is opted into — importing the subpath without it does not throw; only arender*call surfaces an install hint.What it does
ksef-client-ts/pdf— a node-only subpath (renderInvoicePdf,renderInvoicePdfFromTemplate,renderInvoicePdfFromFile,renderUpoPdf) whose types never depend on@types/pdfmake, so consumers without the peer still type-check.ksef invoice pdf— the same rendering from the command line, with the document kind auto-detected.fa2-default,fa3-default,upo-4_2,upo-4_3, plusfa3-showcase, which exists to exercise the DSL rather than to be used on a real invoice.--totalspicks between printing the buckets as recorded, a computed summary, both, or neither. The amount due is always shown; it is the one real total.notes— sections the caller adds beside the document: delivery terms, a payment reminder. Plain text, so a note can neither reach into the invoice nor disturb the layout.Things worth knowing
strictis usable on real documents. It throws on a missing binding, which only works if templates say which bindings a document may legitimately omit — so every optional path is marked exactly where the FA schema allows absence.Fa.P_15is not among them: an invoice always states its amount due, and that one stays policed.Testing
Unit 2673, E2E 150,
tsc, markdownlint, build and the package-export guards all pass.The E2E specs also write a reviewable preview set — 19 PDFs kept in
.pdf-preview/, laid out as a covering design rather than one variant per feature: each row varies several dimensions at once, and two checks fail the suite if a dimension loses its last cover. Sizing has its own spec, because an unreadable QR is still a structurally valid PDF and no render test can see it.🤖 Generated with Claude Code
