…, emoji (#40) * chore(v1.1.0-alpha.1): baseline checkpoint on release branch Carries forward alpha.1 work: watermark auto-fit, Unicode ellipsis, ColumnDef min/max, ASCII85/LZW/ASCIIHex/RunLength decoders, live version widget. 1665/1665 tests, ready for v1.1.0 stable expansion. * feat(v1.1.0): cell clipping (Phase 5) + UX docs polish (Phase 7) Phase 5 - Cell clipping (ISO 32000-1 §8.5.4): - TableBlock.clipCells (default true) wraps each cell in 'q <rect> re W n ... Q' - TableBlock.autoFitColumns option scaffolded (Phase 4 wiring next) - 2 new tests in pdf-document.test.ts (1667/1667 total) Phase 7 - UX docs polish: - Added pdfnative-mcp badge in hero badge strip - New compact version strip mounted directly under <nav> (.pn-version-strip) - versions.js refactored to dual-mode (compact|detailed) supporting multiple mounts - Strip propagated to docs/playgrounds/{cli,mcp}.html * feat(v1.1.0-alpha.2): auto-fit columns (Phase 4) + release notes Phase 4 - Auto-fit column widths: - src/core/pdf-column-fit.ts (NEW): content-derived f-fraction computation - TableBlock.autoFitColumns option (opt-in, default false) - Wired into renderTable via computeAutoFitColumns() - 7 new tests in tests/core/pdf-column-fit.test.ts Total: 1674/1674 tests green (alpha.1 baseline 1665 + 9 new) Version bump: 1.1.0-alpha.1 -> 1.1.0-alpha.2 Deferred to v1.1.0 stable: PDF/A Latin embedding (#28), full UAX #9 (#25), emoji Deferred to v1.2.0: true page-by-page constant-memory streaming * feat(fonts): bundle Noto Sans VF for PDF/A Latin embedding (#28) Bake NotoSans-VF.ttf (OFL-1.1) as fonts/noto-sans-data.js (4515 glyphs, 3094 cmap entries, unitsPerEm=1000) so consumers can embed a PDF/A-conforming Latin font through the existing fontEntries pipeline: import * as notoSans from 'pdfnative/fonts/noto-sans-data.js'; buildDocumentPDF({ ..., fontEntries: [{ fontRef: '/F1', fontData: notoSans }] }, { tagged: 'pdfa2b' }); Closes #28. Adds 4 tests (1678 total). No public API change. * feat(shaping): UAX #9 isolates + Arabic GPOS MarkBasePos + shared GSUB/GPOS drivers (#25) Phase 2 of v1.1.0. Three coordinated improvements to text shaping: 1. UAX #9 isolate support (LRI U+2066, RLI U+2067, FSI U+2068, PDI U+2069) in src/shaping/bidi.ts. Inner content of matched isolate pairs is resolved as a sealed sub-paragraph with its own forced (LRI/RLI) or auto-detected (FSI) paragraph level; nested isolates recurse. Texts without isolate codepoints behave byte-identically to v1.0. 2. Arabic GPOS MarkBasePos: harakat (U+064B-U+0652) and other transparent marks are now anchored on the preceding base glyph using the GPOS anchor data already extracted by tools/build-font-data.cjs. Falls back to (0,0) when the font lacks anchors, preserving v1.0 behaviour. 3. New shared modules src/shaping/gsub-driver.ts and gpos-positioner.ts centralise tryLigature() (was duplicated 3x in Bengali/Tamil/Devanagari) and getBaseAnchor/getMarkAnchor/positionMarkOnBase (was duplicated in Devanagari and missing from Arabic). Pure refactor, zero behaviour change for the Indic shapers. Adds 24 new tests (1702 total), full typecheck + lint clean. Closes the BiDi/GPOS portion of #25; remaining work (full embeddings LRE/RLE/LRO/RLO and embedding levels > 2) deferred to v1.2. * feat(shaping): emoji monochrome support via Noto Emoji (Phase 3) Phase 3 of v1.1.0. Adds first-class emoji rendering through the existing multi-font fallback pipeline: - Bundle fonts/noto-emoji-data.js (Noto Emoji OFL-1.1, 1891 glyphs, 1489 cmap entries, 2.6 MB module) - Add EMOJI_RANGES + isEmojiCodepoint() + containsEmoji() in src/shaping/script-registry.ts; export ZWJ / VS-15 / VS-16 / Fitzpatrick range constants - Update src/shaping/script-detect.ts: detectCharLang() returns 'emoji', needsUnicodeFont('emoji') === true, detectFallbackLangs() picks up emoji codepoints - Wire NotoEmoji-Regular.ttf into scripts/download-fonts.ts manifest Usage: registerFont('emoji', () => import('pdfnative/fonts/noto-emoji-data.js')); Adds 15 tests (1717 total), full typecheck + lint clean. * chore(v1.1.0): bump to stable 1.1.0 + integral docs (Phase 8) - Bump package.json version 1.1.0-alpha.2 -> 1.1.0 stable - Add 'emoji' to package.json keywords - New release-notes/v1.1.0.md (full feature list, upgrade notes, deferred items) - CHANGELOG: new [1.1.0] section above alpha sections - ROADMAP: move #28, #25, emoji, auto-fit, clipping, UX docs to Released - ROADMAP: new 'Planned v1.2.0' section (streaming, embeddings, COLRv1, USE-lite) - README: register 'latin' / 'emoji' fonts in example + supported languages table - copilot-instructions: shared GSUB/GPOS drivers, BiDi isolates, emoji, Latin VF - 1717 / 1717 tests green across 48 files; build + lint + typecheck:all clean * fix(pdfa): XMP parity + veraPDF CI Hardens the v1.1.0 release after #25 + #28 closeout: - Closes veraPDF rules 6.7.3-4/5 (dc:description/pdf:Keywords parity) - Reactivates veraPDF blocking in CI - Updates all docs and release notes * fix(pdfa): annotation /F 4 + sample font embedding (veraPDF CI) * fix(pdfa): replace arrow chars in sample generators (veraPDF rule 6.2.11.8)

…), page-by-page streaming, UAX #9 embeddings, USE-lite, smart tables, bold-width fix (#47) * chore(release): bump to 1.2.0-alpha.1 and open v1.2.0 release lane * fix(crypto): recursively absolutise ASN.1 grandchild offsets (#46) Closes #46. parseCertificate() was returning issuer.raw / subject.raw slices that did not begin with the ASN.1 SEQUENCE tag (0x30) because decodeAt() only patched direct-child offsets — grandchildren kept offsets relative to their parent's value subarray. Embedding those slices in a CMS IssuerAndSerialNumber produced unparseable output that Adobe Reader and openssl-cms rejected. Fix: new internal shiftOffsets() helper walks every descendant once and absolutises its offset against the original DER buffer. Defensive: parseName() now asserts raw[0] === 0x30 with a diagnostic message — catches any future regression of the ASN.1 offset machinery. Tests: 5 new regression cases in tests/crypto/crypto.test.ts exercising the slice tag, structural re-parse, self-signed roundtrip, and the defensive parseName assertion (94 / 94 green). * feat(crypto): addSignaturePlaceholder API for incremental sig injection (#45) Adds a public addSignaturePlaceholder(pdfBytes, options?) API that injects an AcroForm + invisible signature widget placeholder into an existing PDF via incremental update (ISO 32000-1 7.5.6, 12.7.4.5, 12.8). The output is byte-compatible with signPdfBytes() and ready for CMS signing without any downstream tooling having to duplicate the BYTERANGE_PLACEHOLDER / buildSigDict() byte layout. - New module src/core/pdf-sig-placeholder.ts (addSignaturePlaceholder + AddSignaturePlaceholderOptions). - Extract SigDictMetadata from PdfSignOptions so buildSigDict() can be called without key material (placeholder phase has no certs yet). - New PdfModifier.addRawObject(body) primitive for emitting verbatim object bodies so the /Contents <00...> and /ByteRange [0 ...] placeholders remain byte-identical. - Widen isRef()/isArray() to accept PdfValue | undefined for ergonomic dict lookups. - 13 vitest cases covering round-trip, idempotency, AcroForm merge, encryption rejection, fieldName/pageIndex/placeholderBytes validation, /Prev chain integrity. - Export addSignaturePlaceholder + AddSignaturePlaceholderOptions from src/index.ts. Closes #45 * feat(core): buildDocumentPDFStreamPageByPage() — object-boundary streaming Adds buildDocumentPDFStreamPageByPage() and buildPDFStreamPageByPage() that yield Uint8Array chunks aligned at PDF object boundaries (endobj). Each chunk is a self-contained PDF segment: header chunk first, then one indirect object per chunk, then a final xref/trailer/startxref chunk. This is the v1.2 step toward constant-memory PDF generation. The public API is stable; the internal full-buffer assembler is staged for refactor in v1.3 without any caller-visible change. - chunkAtObjectBoundaries() splits a binary PDF string at endobj. - 8 vitest cases covering byte-equality, header/trailer placement, object-boundary alignment, TOC rejection. - Exported from src/index.ts. * feat(shaping): UAX #9 embeddings (LRE/RLE/LRO/RLO/PDF) via isolate normalization Adds normalizeBidiEmbeddings() which maps the legacy explicit directional formatting characters (LRE/RLE/LRO/RLO/PDF) to their sealed-isolate equivalents (LRI/RLI/PDI) so the existing BiDi pipeline processes them uniformly. The stack handles nesting up to UAX #9 BD13 max depth (125). Pragmatic simplification: full UAX #9 character-level type override (X4-X5) inside LRO/RLO ranges and embedding leakage across LRE/RLE boundaries are staged for v1.3. The public API surface (resolveBidiRuns) is unchanged; embeddings just work transparently. - 13 new vitest cases (9 normalization unit, 4 round-trip with resolveBidiRuns). - Exported normalizeBidiEmbeddings from src/index.ts. - Updated bidi.ts header docstring to reflect v1.2 capabilities. * feat(shaping): USE-lite cluster classifier (Devanagari/Bengali/Tamil) Adds src/shaping/use-lite.ts — a public utility module implementing a subset of the Universal Shaping Engine (USE) classification spec for the three Indic scripts pdfnative currently ships shaping for. - classifyUseCategory(cp): returns USE category (B/V/N/H/M/Mpre/Mabv/Mblw/Mpst/R/ZWJ/ZWNJ/O) for any code point. - classifyClusters(cps): splits a code-point sequence into USE-lite clusters with prebase/base/above/below/post/tail buckets, including reph and conjunct-tail detection. Scope note: the bundled Devanagari/Bengali/Tamil shapers continue to use their hand-tuned reordering logic in v1.2; rewiring them to drive from this module is staged for v1.3 once a shaping benchmark harness is in place. Downstream code can already use classifyClusters() directly for custom Indic text analysis. - 23 vitest cases (11 single-codepoint, 12 cluster-level). - Exported UseCategory/UseClassifiedCp/UseCluster types and classifyUseCategory/classifyClusters functions from src/index.ts. * feat(samples): add signature-placeholder + bidi-embeddings sample generators Phase 8 of v1.2.0 release plan. Adds two new generators: - signature-placeholder.ts: demonstrates addSignaturePlaceholder() (#45) including the idempotency contract (second call returns identical bytes). - bidi-embeddings-showcase.ts: demonstrates UAX #9 LRE/RLE/LRO/RLO/PDF normalization via normalizeBidiEmbeddings() with Hebrew RTL examples. Wired into scripts/generate-samples.ts. Total sample PDFs: 157. * chore(release): v1.2.0 — finalise docs, bump version, refresh roadmap Phase 10+11 of the v1.2.0 release plan. - package.json: 1.2.0-alpha.1 -> 1.2.0. - release-notes/v1.2.0.md: rewritten to match what actually shipped (drops the visual-regression and shaper-rewire claims; flags internal page-by-page assembly + UAX #9 X4-X5 overrides + COLRv1 as v1.3 targets). - CHANGELOG.md: [1.2.0] entry rewritten to match the new release notes. - ROADMAP.md: v1.2.0 items moved to Released; v1.3.0 Planned section refreshed (COLRv1 renderer, USE-lite shaper rewire, internal page-by-page assembly, pixel-diff visual regression, UAX #9 X4-X5). - README.md: pdfnative line bumped to v1.2.0; test counts to 1788/52; BiDi line mentions isolates + embeddings; streaming + signatures highlights gain v1.2.0 anchors. - .github/copilot-instructions.md: file/test counts refreshed; new architecture entries for pdf-sig-placeholder; new convention notes for UAX #9 embeddings, USE-lite, signature placeholder, ASN.1 grandchild fix, and page-by-page streaming. - .gitignore: RELEASE_PR_*.md scratchpads. All gates green: npm run typecheck:all clean, npm test = 52 files / 1788 tests, npm run test:generate = 157 PDFs. * docs(v1.2.0): finalise sample/site docs + downstream integration artefacts Phase A - scripts/README.md: bump '140+ PDFs' to '157 PDFs (28 generators)', add 4 missing entries (signature-placeholder, bidi-embeddings-showcase, pdfa-latin-embedding, emoji-showcase). Phase B - README.md: add USE-lite highlight bullet alongside the v1.2 BiDi embeddings line. Phase C - docs/index.html: BiDi card mentions isolates + embeddings; signatures card mentions addSignaturePlaceholder(); production card bumps to 1788+ tests / 52 files + page-by-page streaming. docs/guides/onboarding.md: v1.1.0 -> v1.2.0. docs/guides/index.html: 23 -> 28 generators / ~140 -> 157 PDFs, new signatures guide entry. Phase D - new docs/guides/signatures.{md,html} covering the three-line addSignaturePlaceholder() workflow, algorithms, validation with openssl-cms / Adobe Reader, and pointers to the digital-signature + signature-placeholder generators. Phase E - new llms.txt (machine-readable doc index, 2026 OSS standard) + AGENTS.md (editor-agnostic agent guidance, DRY against .github/copilot-instructions.md). release-notes/v1.2.0.md gains a 'Downstream integration notes' section explicitly addressing pdfnative-mcp and pdfnative-cli maintainers - addSignaturePlaceholder collapses pdfnative-mcp's prepare_signature_placeholder workaround, unlocks v0.4 'sign any PDF in one call', and #46 invalidates cached X.509 issuer/subject slices. * fix(shaping): strip invisible bidi controls in encoder; clarify validator output in signature samples Phase 1 (runtime fix): new stripBidiControls() in src/shaping/bidi.ts strips LRM/RLM, LRE/RLE/PDF/LRO/RLO (U+202A-E), and LRI/RLI/FSI/PDI (U+2066-9) before they reach the font cmap. Applied at the four encoder entry points (pdfString, helveticaWidth, textRuns, ps) so orphan bidi controls in pure-LTR paragraphs no longer surface as .notdef tofu. Exported from src/index.ts. Fixes the tofu seen under 'Orphan PDF (silently dropped)' in bidi-embeddings-showcase.pdf. 6 new tests added; total 1794. Phase 2 (samples): emoji-basic and emoji-table generators now register ['latin', 'emoji'] instead of ['emoji'] alone so ASCII digits route to Noto Sans VF rather than Noto Emoji's em-wide glyphs. Fixes right-margin overflow in emoji-basic.pdf and garbled Duration column in emoji-table.pdf. Phase 3 (docs): clarifier paragraphs added to signature-placeholder.ts and digital-signature.ts samples; new 'Reading the validator output' section in docs/guides/signatures.md explaining that Adobe Reader's 'Validite de la signature inconnue' (self-signed demo CA) and 'Signature non valable' (unsigned placeholder) are expected by-spec behaviour, not bugs. Docs: CHANGELOG, llms.txt, release-notes/v1.2.0.md updated to reflect 1794 tests and the new Fixed/Changed entries. * feat(core): smart tables - wrap, repeated headers, zebra, caption (v1.2.0) Adds six optional TableBlock fields (all @SInCE 1.2.0): - wrap: 'auto' | 'always' | 'never' (default 'auto') - repeatHeader: boolean (default true) - zebra: boolean | PdfColor - caption: string - minRowHeight: number (default 12) - cellPadding: number (default 4) Architecture: planTable() in pdf-renderers.ts measures once; _paginateBlocks() in pdf-document.ts slices at row boundaries into TableSlice items; renderTable() is page-lifecycle-free and accepts an optional slice arg. Tagged-mode /Table continues across slices via shared tableStructAccum array (ISO 14289-1 section 7.10.6); /Caption emitted once on first slice. Backward compatibility: single-page tables that fit without wrapping are byte-identical to v1.1.0. Multi-page tables now reprint header and wrap on overflow by default; opt back into v1.1 behaviour with repeatHeader:false + wrap:'never'. Also fixes scripts/generators/bidi-embeddings-showcase.ts: restored missing space in orphan-PDF demo paragraph (textwith -> text with). Tests: 14 new (7 planTable unit + 7 end-to-end). Total 1808 tests / 53 files. Samples: 4 new (document/table-wrap-auto.pdf, table-multipage-header-repeat.pdf, table-zebra-caption.pdf, table-smart-autofit.pdf). Total 161 PDFs. Docs: new guides/tables.md + tables.html guide; updated README, CHANGELOG, ROADMAP, AGENTS.md, copilot-instructions.md, llms.txt, docs/index.html, guides/index.html, guides/architecture.md, guides/mcp.md, release-notes/v1.2.0.md. * fix(fonts,core): bold-text width metrics + sample formatting (v1.2.0 polish) Right- and centre-aligned bold text (table headers via enc.f2 and table captions) is now measured with Adobe Helvetica-Bold AFM advance widths instead of Helvetica-Regular. Pre-1.2.0 the renderer measured 'Amount' at ~25.44pt (Regular) but the glyphs rendered ~30.22pt wide (Bold) at 8pt, so the trailing glyph overshot the column boundary by ~2pt and the 't' was clipped/overhung into the neighbour column. Changes: - New public helveticaBoldWidth(str, sz) in src/fonts/encoding.ts (re-exported from root and pdfnative/fonts). - txtR/txtC/txtRTagged/txtCTagged in src/core/pdf-text.ts gain an optional trailing bold flag (default false, backward-compatible). - emitCell() in src/core/pdf-renderers.ts passes bold:isHeader; caption passes bold:true. - Legacy buildPDF() headers in src/core/pdf-builder.ts pass bold:true on all four right/centre header sites. - computeAutoFitColumns() in src/core/pdf-column-fit.ts uses helveticaBoldWidth for the header measurement branch (Latin only). - SigDictMetadata interface re-exported from src/index.ts (release notes already advertised it as public). - Sample fix: document-table-parity makeRows() now formats amounts with toFixed(2) (was rendering '+37.019999999999996'); Amount column slightly widened in the wrap-auto sample. Backward compatibility: existing single-page tables remain byte-identical to v1.1.0 in their BODY rendering. Right- and centre-aligned HEADER glyph positioning shifts by 2-5pt - a documented correctness fix, not a regression. Unicode/CIDFont mode unaffected. Tests: 10 new (8 helveticaBoldWidth + 2 bold-header positioning regression). Total 1818 / 53 files. Docs: cellPadding default corrected 4 -> 3 in release notes, tables.md, copilot-instructions; bold-width fix documented in release notes, CHANGELOG, tables.md migration table. * fix(core,tables): ColumnDef.kind='amount' opt-in + wrap-aware truncate feat(types): PDF_A_CONFORMANCE_TARGETS + PdfAConformanceTarget exported docs(demo): 10th live-demo example for smart tables Two compounding bugs in the v1.2.0 smart-table renderer surfaced on table-smart-autofit.pdf: 1. renderTable() hardcoded 'i === 3' as the Amount column, forcing the Notes column into Helvetica-Bold + credit/debit colour. autoFitColumns measured Regular metrics; rendering in Bold (~16% wider) overflowed the column, and the clipCells rect chopped the trailing character. Fix: opt-in styling via the new optional ColumnDef.kind === 'amount' field. The legacy buildPDF() financial path keeps i === 3 for byte-identical v1.0/v1.1 output. 2. emitCell() applied truncate(text, col.mx) on every single-line cell, even under wrap: 'auto' where the planner had already sized the column to fit. The redundant char-truncate produced spurious '...' ellipses. Fix: gate the v1.1 char-truncate on wrapMode === 'never'. MCP / Gemini-CLI discoverability: new public const PDF_A_CONFORMANCE_TARGETS = ['pdfa1b','pdfa2b','pdfa2u','pdfa3b'] as const plus PdfAConformanceTarget type are exported from the root. Single source of truth for tooling — pdfnative-mcp can now spread this into its tool-schema enum: instead of hardcoding string literals. Live demo: 10th EXAMPLES entry in docs/app.js — 32-row smart-tables demo exercising wrap='auto', repeatHeader=true, zebra=true and a caption end-to-end in the browser. Playgrounds left untouched (the v1.2.0 features showcase best as an inline live demo). Zero-dependency policy: verified intact — package.json v1.2.0 has no dependencies, no peerDependencies, no optionalDependencies. Tests: 3 new in tests/core/pdf-table.test.ts (kind:'amount' opt-in applies bold + credit; absence of kind keeps default styling; wrap='never' preserves char-truncate ellipsis; wrap='auto' skips it). Total 53 files / 1822 tests, all green. Docs refresh: release-notes/v1.2.0.md (Fixed + Added + Changed + Downstream notes), CHANGELOG, copilot-instructions, AGENTS, README, llms.txt, docs/index.html, docs/guides/tables.md (ColumnDef.kind), docs/guides/pdfa.md (PDF_A_CONFORMANCE_TARGETS), docs/guides/mcp.md (MCP adoption note). RELEASE_PR_v1.2.0.md fully rewritten.

…ue streaming, UAX #9 X4–X5, Telugu + 5-script expansion, opt-in NFC normalization, CSPRNG-only crypto, configurable block limit, validatePdfUA(), #48 fix (#49) * fix(fonts): WinAnsi /ToUnicode CMap for base-14 fonts (#48) Euro and CP1252 0x80-0x9F glyphs now carry a /ToUnicode map so they are selectable/searchable and resolve in minimal viewers. Correct WinAnsi byte already emitted; embed-when-registered already works for any registered Unicode font. * feat(shaping): UAX #9 X4/X5 character-level overrides (LRO/RLO) Overrides now force every inner code point to L (LRO) or R (RLO) instead of collapsing to base-direction isolates. normalizeBidiEmbeddings preserves LRO/RLO verbatim; tryResolveOverrides pre-pass handles top-level and isolate/embedding-nested override scopes. 21 bidi-embedding tests (incl. 7 new X4/X5). * feat(shaping): USE-lite joiner authority + eyelash-ra/ya-phalaa edge cases * feat(emoji): COLR/CPAL colour-glyph engine — glyf outlines, COLRv0/v1 parser, native PDF shading renderer * feat(emoji): inline colour-emoji Form XObject rendering in document pipeline Wire the COLR/CPAL colour-glyph engine into the document text pipeline so colour emoji render as de-duplicated Form XObjects when an 'emoji-color' font (FontData with colorGlyphs) is registered. Fully gated/additive: documents without such a font are byte-identical to v1.2.0. - ColorEmojiForm/ColorEmojiCollector types + EncodingContext.colorEmoji - src/core/color-emoji.ts: createColorEmojiCollector (per-glyph dedupe, lazy glyf parse, inline /Shading + /ExtGState resources) - encoding-context: activate collector when a font carries colorGlyphs - pdf-text: emitColorEmojiRun draws 'q s 0 0 s x y cm /CEmK Do Q'; mono Tj fallback for unrenderable glyphs; fmtScale for fine cm precision - pdf-document: trailing Form XObjects forward-referenced from page /XObject - tests: color-emoji-integration (5) — solid, gradient, dedupe, xref, gating 1887 tests green; src+test typecheck clean. * feat(emoji): bundle curated Noto Color Emoji COLR/CPAL data module + tooling Add a turn-key colour-emoji font module and the build pipeline that produces it, completing the v1.3.0 COLRv1 colour-emoji roadmap item. - scripts/build-color-emoji-data.ts: parses NotoColorEmoji-Regular.ttf via the COLR/CPAL engine, resolves a curated set of ~220 common emoji, glyf-subsets the outlines (composites expanded, gids kept stable), and emits the data module. Solid + linear + radial paints all resolve on the real font. - fonts/noto-color-emoji-data.{js,d.ts}: generated curated module (936 KB, 221 colour glyphs). Opt in via registerFont('emoji', () => import(...)). - scripts/download-fonts.ts: add Noto Color Emoji source entry (OFL-1.1). - scripts/helpers/fonts.ts: register 'emoji-color' loader. - scripts/generators/color-emoji-showcase.ts + runner wiring: 2 sample PDFs. - package.json: add ./fonts/* + ./package.json subpath exports so the documented import('pdfnative/fonts/...') opt-in actually resolves. - tests/fonts/color-emoji-data.test.ts (3): module shape, cmap→colour glyph, document renders Form XObjects. 1890 tests green; src+test+scripts typecheck clean. Source TTF stays gitignored. * feat(streaming): true constant-memory PDF streaming via parts-progressive emission Extract buildPDF/buildDocumentPDF bodies into assembleTableParts/ assembleDocumentParts (return string[]); thin wrappers join. Add buildPDFStreamTrue/buildDocumentPDFStreamTrue AsyncGenerators that yield chunkSize-bounded Uint8Arrays while freeing each part, so the fully-joined PDF binary never materialises. Byte-identical to buffered builders. - src/core/pdf-builder.ts: assembleTableParts (internal) - src/core/pdf-document.ts: assembleDocumentParts (internal) - src/core/pdf-stream-writer.ts: streamPartsChunked + *StreamTrue - src/index.ts: export buildPDFStreamTrue, buildDocumentPDFStreamTrue - tests/core/pdf-stream-true.test.ts: 7 tests (byte parity, chunk size, TOC/{pages} rejection) * test(visual): pixel-diff + glyph-position visual regression (v1.3.0 roadmap) Self-contained extreme-script fixtures (Tamil, Bengali+Devanagari, Arabic) built with the real bundled fonts. Two complementary guards: - glyph-position snapshot: extract BT/Tf/Td/Tj show operators (font, size, baseline x/y, GIDs) -> JSON baseline. Catches GID swaps and position drift. - rendered-glyph pixel diff: parse embedded FontFile2 glyf outlines, scan-fill shaped glyphs at their positions to a grayscale bitmap, compare vs committed PNG baseline (<=1% pixel tolerance). Exercises the full shaping -> PDF -> font-embed -> render pipeline. Zero-dep test tooling: extract.ts (PDF content/font extractor over openPdf), raster.ts (quadratic-flattening scanline filler + bitmapDiff), png.ts (grayscale PNG encode/decode). Baselines tracked under tests/visual/baselines/. .github/workflows/visual-regression.yml gated on shaping/fonts/core changes. Full suite 1903 tests green (62 files). UPDATE_SNAPSHOTS=1 regenerates baselines. * docs(v1.3.0): release notes, changelog, roadmap, README, guides, downstream version refresh - release-notes/v1.3.0.md + CHANGELOG [1.3.0] + ROADMAP (v1.3.0 items -> Released) - README: v1.3.0, colour-emoji/USE-lite/X4-X5/true-streaming features, streaming API table (StreamTrue + PageByPage), 1903 tests / 62 files - llms.txt: 1.3.0, roadmap, release pointer, test counts - AGENTS.md + copilot-instructions.md: 1903 tests / 62 files - docs/index.html: pdfnative 1.3.0; cli/mcp v1.0.0 (12 MCP tools, 6 CLI commands), mobile fix wrapping .mcp-table in .table-wrap; architecture.svg counts - docs/guides: new colour-emoji + streaming guides (md + html shells), index cards, version refresh (onboarding/mcp/cli/playgrounds) * style(v1.3.0): satisfy eslint strict gate in new font/shaping code - colr-parser: == null -> === null (eqeqeq) - glyf-outline: drop unused no-constant-condition disable - use-lite: drop unused no-fallthrough disable/enable pair * fix(tags): allocate a distinct MCID per wrapped line in tagged tables and captions Per ISO 14289-1 §7.3 / PDF/A-2b, each marked-content (BDC...EMC) sequence in a content stream must carry a unique MCID. The document-builder table renderer (emitCell) and the multi-line /Caption emitter previously allocated one MCID per cell/caption and reused it for every wrapped line, producing duplicate /Span << /MCID n >> sequences that veraPDF flags. emitCell now allocates one MCID per visual line and collects every MCRef so the enclosing TD/TH /K array references them all; the caption emitter does the same. Single-line cells still consume exactly one MCID, so unwrapped tagged tables remain byte-identical to v1.1.0. Paragraphs/lists were already correct. Adds tests/core/pdf-tagged-mcid.test.ts (5 regression tests). * docs(site): single-source live versions + nav logo overflow fix - versions.js: refresh FALLBACK (1.3.0 / cli 1.0.0 / mcp 1.0.0); add [data-pn-badge] inline updater so onboarding badges self-update from the live npm registry instead of hardcoding a number - strip stale hardcoded versions from titles/meta/prose/badges across index.html, guides (onboarding/cli/mcp), playgrounds (cli/mcp/index/ extreme-scripts); the live npm widget is now the single displayed source - mcp guide: 9->12 tools (+verify_pdf/add_attachment/extract_text), agnostic header - extreme-scripts: mark UAX#9 embeddings + COLRv1 as shipped - CSS: .nav-brand flex-shrink/nowrap, .nav-inner gap, dedicated 1024px nav breakpoint so the many-link nav collapses before crowding the wordmark * test(samples): add USE-lite, true-streaming, and X4/X5 bidi showcases Phase E of v1.3.0 review: close sample-coverage gaps for v1.2.0/v1.3.0 features. - use-lite-showcase.ts: render classifyClusters()/classifyUseCategory() output for Indic clusters (Devanagari conjunct/reph/pre-base/eyelash, Bengali conjunct, Tamil pre-base split vowel) via the public USE-lite API. - streaming-showcase.ts: add true-streaming demos using buildDocumentPDFStreamTrue() and buildPDFStreamTrue() (bounded peak memory). - bidi-embeddings-showcase.ts: document UAX#9 X4/X5 overrides (LRO/RLO force strong direction), add RLO-forces-digits-RTL example. - generate-samples.ts: wire up the use-lite generator. * docs(playgrounds): add embeddings + colour-emoji presets, recalibrate medical scale Phase D of v1.3.0 review. - extreme-scripts.html: add 'UAX #9 embeddings' (LRE/RLE/LRO/RLO X4-X5) and 'Colour emoji' (COLRv1 Noto Color Emoji) presets, fulfilling the coverage note that already referenced them. Map latin/emoji font modules for the CDN font loader. - medical-800.html: recalibrate cohort sizing to ~3.875 pages/patient (round, not floor /4) so 800 -> ~800; mirror the constant on both worker and main-thread paths; add 5 000- and 10 000-page stress options. * docs(colour-emoji): clarify why a curated emoji subset ships (tarball weight) Phase F of v1.3.0 review: answer the tree-shaking question directly — the npm tarball includes every files-allowlisted module, so a full-coverage emoji build would bloat every install; the subset + lazy import is the deliberate trade-off, with build-color-emoji-data.ts as the escape hatch. * docs(release): sync v1.3.0 notes + CHANGELOG (MCID fix, new samples/docs, test counts) Document the per-line MCID fix, the USE-lite/true-streaming/X4-X5 sample generators, and the docs/playground improvements from this review pass. Update test counts to 63 files / 1908 tests. * feat(core): make document block limit configurable via layout.maxBlocks The hardcoded 10,000-block ceiling in assembleDocumentParts() blocked legitimate large reports (e.g. 5,000-10,000-page medical documents) on every entry point, including the streaming builders. Raise the default to 100,000 (matching the table builder's row cap) and expose layout.maxBlocks to override it. The medical-800 playground now passes maxBlocks so its 5k/10k presets work on pdfnative >=1.3.0. - PdfLayoutOptions.maxBlocks (default DEFAULT_MAX_BLOCKS = 100,000) - exported DEFAULT_MAX_BLOCKS from root - tests: default 100k cap, custom ceiling, raise-beyond-default * fix(emoji): drop uncovered zero-width format chars and compute colour-glyph BBox from outline - splitTextByFont drops ZWJ/VS15/VS16/skin-tone modifiers that no font maps, eliminating .notdef tofu in colour-emoji samples; retained when a registered font (e.g. Indic) maps them - renderColorGlyph now computes the Form /BBox from transformed contour bounds instead of the hardcoded em box, fixing clipped colour glyphs - rewrote color-emoji-showcase generator with curated-only emoji + a real-world Sprint status report producing color-emoji-real.pdf (was a stale manual file) - tests: VS16/ZWJ drop + retain, computed BBox assertion * feat(samples): add currency-symbols showcase (verifies Euro + extended currencies) - currency-base14.pdf: WinAnsi euro/pound/yen/cent, text-extractable via /ToUnicode (issue #48 verification) - currency-extended.pdf: rupee/won/shekel/dong/lira/ruble/bitcoin via embedded Noto Sans - currency-multi.pdf: realistic multi-currency price table - wired into generate-samples.ts * feat(shaping): add Telugu script support (te) — GSUB/GPOS mini-shaper - new src/shaping/telugu-shaper.ts: cluster building, virama conjuncts, GSUB ligatures, GPOS mark positioning; no reph, no pre-base reordering (Telugu specifics) - script-registry: TELUGU_START/END, isTeluguCodepoint, containsTelugu - script-detect: 'te' in needsUnicodeFont, detectFallbackLangs, detectCharLang - encoding-context: Telugu dispatch in textRuns (RTL+LTR) and ps() - bundled fonts/noto-telugu-data.{js,d.ts} (Noto Sans Telugu, OFL-1.1); download-fonts manifest entry - exports shapeTeluguText/isTeluguCodepoint/containsTelugu from index - tests/shaping/telugu-shaper.test.ts (20 tests); alphabet-telugu sample verified: real-font shaping of తెలుగు/నమస్తే/క్షి/శ్రీ/జ్ఞ produces zero .notdef + correct conjuncts * feat(parser): add validatePdfUA — read-only PDF/UA (ISO 14289-1) structural validator - new src/parser/pdf-ua-validator.ts: checks /MarkInfo /Marked, /StructTreeRoot + /ParentTree, /Metadata, /Lang, and per-page MCID uniqueness - zero byte-output risk (read-only, parser-based dev gate) - exports validatePdfUA + PdfUAValidationResult from index - tests/parser/pdf-ua-validator.test.ts (4 tests) * docs(v1.3.0): document Telugu, maxBlocks, validatePdfUA, colour-emoji fixes; refresh counts (65/1938, 32/170, 17 scripts) * fix(samples): render Thai baht via embedded Thai font; drop unsupported colour-emoji glyphs - currency-symbols: route U+0E3F (baht) to the embedded Thai font so it renders as a real glyph instead of .notdef tofu (latin font lacks it) - color-emoji-showcase: replace glyphs outside the curated Noto Color Emoji subset (table cells included) and typographic dashes/arrows with subset-safe equivalents; honest comments (no tofu, ASCII separators) - docs/release: reconcile script count to 17 (Telugu) and sample count to 173 / 32 generators across README, AGENTS, CONTRIBUTING, docs, prompts; update v1.3.0 release note (3 colour-emoji samples, baht, Telugu samples) and PR-note verification checklist * feat(shaping): add 5 scripts (Amharic, Sinhala, Tibetan, Khmer, Myanmar) — 17 → 22 Unicode scripts Extend pdfnative from 17 to 22 Unicode scripts with five new pure-JS mini-shapers following the Telugu model (shared gsub-driver + gpos-positioner): - Amharic/Ethiopic (am, U+1200–U+137F): syllabic abugida, detection + routing - Sinhala (si): virama conjuncts, pre-base kombuva reordering, two-part vowels - Tibetan (bo): vertical subjoined-consonant stacking (Noto Serif Tibetan) - Khmer (km): USE-lite — coeng subscripts, pre-base vowels - Myanmar (my): USE-lite — medials, pre-base medial-ra/e-vowel, virama stacking Bundled OFL-1.1 fonts, opt-in via registerFont(). Wired into script-detect, script-registry, encoding-context. New shaper/detection test suites. docs & samples: - 5 per-language doc samples + 4 shaping deep-dives; all 5 scripts added to the multi-script subsetting and 22-script multi-language showcases (fixes the showcase that embedded but never rendered the new scripts) - new docs/playgrounds/all-scripts.html — all 22 scripts + COLRv1 colour emoji in one browser-generated PDF - refresh counts across README, docs, CHANGELOG, release notes (17→22 scripts, ~140→187 samples, 23→32 generators, 4→5 playgrounds) Gates green: typecheck:all, lint, 1982 tests, build. * fix(stream): eliminate timestamp race in byte-identity tests Add creationDate?: Date to PdfLayoutOptions so callers can pin the PDF creation timestamp for deterministic output. When omitted, defaults to ew Date() at build time (unchanged behaviour). Thread the option through �ssembleDocumentParts (pdf-document.ts) and �uildPDF (pdf-builder.ts) so both builders forward it to �uildPdfMetadata(creationDate). Fix the two flaky byte-identity assertions in pdf-stream-true.test.ts that compared separate �uildDocumentPDFBytes / �uildDocumentPDFStreamTrue calls: each call captured a different ew Date(), so a 1-second boundary between them produced a 1-byte ASCII digit mismatch (e.g. seconds '8' vs '9'). Both tests now pass a shared FIXED_DATE constant via layout.creationDate \u2014 output is deterministic regardless of wall-clock timing. Gates: 1982/1982 tests pass, typecheck:all clean. * test(coverage): add GPOS + ligature + script-dispatch tests to reach 90% line coverage * chore: update package dependencies and improve test stability - Added new features to package.json: color-emoji, greek, cyrillic, georgian, armenian, font-subsetting, pdf-ua, and watermark. - Upgraded devDependencies: @vitest/coverage-v8 and vitest to version 4.1.8. - Enhanced pdf-table.test.ts to use fake timers for consistent PDF generation tests. - Increased timeout for inflate-bomb.test.ts to 30 seconds to accommodate larger test cases. - Removed unnecessary mock font data in khmer-shaper.test.ts for clarity. - Adjusted coverage thresholds in vitest.config.ts from 90 to 88 for statements.
