Changelog

All notable changes to Paradoc. Packages are versioned in lockstep.

[Unreleased]

[0.5.0] - 2026-08-10

Added

• Unified signatures slot map on layers. Each slot binds a party to a placement: 'auto' (an invisible marker injected at render time and located after conversion), a text anchor (unique in the document, or selected with occurrence), or absolute coordinates. One placement engine resolves all three, and misconfiguration fails before rendering with a SealConfigError naming every problem. Legacy signatureBlocks/anchorBlocks still parse and seal unchanged.
• A built-in placement locator in @paradoc/render: a dependency-light PDF text scanner (locate, extractFieldsFromPdf, pageTextRuns, marker encoding) that resolves signature positions in converted PDFs without a PDF rendering engine. Exported from @paradoc/render/pdf and re-exported by @paradoc/sdk.
• prepareSeal() on draft forms: resolves the signature map and returns the exact pre-flatten PDF it describes, with per-field provenance (declared | anchor | marker) and warnings, without changing the form's phase.
• SealOptions.locate to substitute a custom placement locator.
• The schema version 2026-08-10 adds the SignatureSlot layer schema; the published 2026-08-06 schemas remain available unchanged.

Changed

• Anchor-based sealing works with pure byte converters, including hostedSealAdapter, with zero configuration: core locates anchor text itself in the converted PDF. Adapters that resolve placements themselves still take precedence.
• The sealing guide is rewritten around signature slots, placement strategies, and pure converters.

Fixed

• PdfModel resolves indirect /Length stream references, so PDFs written by LibreOffice no longer lose trailing stream bytes.

Removed

• The unused SealingRequest.options block (renderer, format). It was never read by any implementation.

[0.4.0] - 2026-08-06

Changed

• Form rendering and sealing use the built-in MIME-selected renderer by default while preserving custom renderer overrides. The CLI and integrations use the same unified renderer.
• The current schema version is 2026-08-06; the published 2026-01-01 schemas remain available unchanged.

Added

• @paradoc/render, a dependency-light renderer for text, Markdown, HTML, PDF, and DOCX layers, including template control flow, PDF AcroForm filling, overlays, inspection, page selection, and flattening.
• Recursive List fields across builders, types, schemas, validation, serialization, and rendering.
• A sealing boundary with local PDF flattening and optional adapters for non-PDF conversion.

Removed

• The legacy @paradoc/renderers, @paradoc/renderer-text, @paradoc/renderer-pdf, and @paradoc/renderer-docx packages.
• Heavy PDF, DOCX templating, and Handlebars dependencies from the rendering and e-signing paths.

[0.3.0] - 2026-06-19

Added

• @paradoc/expr: a purpose-built, typed expression language for artifacts — a parser, an evaluator, and an artifact-aware type checker sharing one function registry. Exact-decimal arithmetic (no floating-point drift), temporal types (date, datetime, time, duration), in / not in, and null-safe access.
• @paradoc/sessions is now published: the deterministic, event-sourced form-completion session engine.
• Dependency-aware fill state: a single status ordinal (hidden, optional, required), transitive blockedBy, and DAG-ordered next-field.
• The expression engine is reachable through @paradoc/sdk as the expr namespace (expr.check, expr.parse, expr.Decimal).
• Documentation for @paradoc/sessions and @paradoc/expr, and the fieldset visibility cascade.

Changed

• Artifact logic now runs on @paradoc/expr. A hidden fieldset hides its entire subtree, and a child's required follows its effective visibility.

Removed

• The expr-eval-fork dependency.
