Introduce detailed console logging across document parsing API routes and worker
operation state fetches. Logs now capture stream openings, error conditions,
worker state unavailability, and invalid responses, improving observability and
debuggability for PDF parsing and ONNX layout processing flows.
Update PDF viewer and document hook to improve parse status management:
- Set parseStatus to null on clear instead of 'pending' for accurate state
- Explicitly set initial parseStatus and reset parseProgress when loading a new document
- Adjust loader display logic to check for resolved parse status before showing expanded loader
Prevents UI inconsistencies and ensures parse progress is reflected correctly during document transitions.
Introduce idle and hard cap timeouts for PDF layout parsing in the compute worker,
ensuring long-running jobs are capped and progress is tracked with explicit
timeouts. Refactor NATS JetStream client initialization to use a configurable
API timeout. Update PDF viewer UI to treat parse state as 'pending' by default,
improving clarity during document preparation and parsing. Refine parse loader
labels and progress logic for more accurate user feedback.
Introduce detailed progress reporting for PDF layout parsing, exposing phase and page-level updates to clients. Replace legacy parseStatus with a structured parseState field in the database schema, updating all relevant backend and API logic. Add SSE endpoint for real-time parse progress updates. Update client hooks and UI to reflect granular progress and improve user feedback during document parsing. Includes migration scripts and new parse-state utility module.
Eliminate the smartSentenceSplitting configuration flag from application state, UI, and all TTS and audiobook adapter logic. Consolidate TTS segment planning to always include context units, streamlining code and reducing conditional branches. Update tests and type definitions to reflect the removal of this feature toggle.
Update TTS segment prefetching logic to handle arrays of CanonicalTtsSourceUnit for upcoming and next locations, enabling more precise TTS segment mapping. Expand cache key construction to include providerType and instructions, improving cache differentiation for TTS requests. Adjust related types and usages to support richer segment metadata propagation.
Introduce sourceUnitsFromParsedPage helper to extract CanonicalTtsSourceUnit
objects from parsed PDF pages, filtering by block kind and text content. Update
TTS state setter to include extracted source units when available, enabling
improved TTS segment mapping and future extensibility.
Unify and improve layout settling logic across EPUB, HTML, and PDF viewers by
adding delayed recomputation and guarding against zero-height container during
transient states. Refactor PDF document loading to include retry logic with
success detection, ensuring robust handling of transient failures. Update
Playwright test helpers to provide more reliable PDF viewer readiness checks
and introduce request retry utilities for backend API calls. Add targeted unit
tests for single-section chapter fallback in the PDF audiobook adapter. Update
test files and helpers to align with new layout and export logic.
Eliminate unused PDF text extraction logic and margin-based filtering from the client library. Refactor API routes to generalize parse status normalization, removing explicit references to deprecated "unsupported" status and type variants. Update usages to accept string parse statuses for improved flexibility. Simplify document state dependency tracking in the PDF document hook.
Eliminate the "none" compute mode and all related code paths, including the NoneComputeBackend, "unsupported" parse status, and PDF margin settings. Parsing is now always available if the app starts successfully, and configuration is limited to "local" or "worker" compute modes. Update types, API routes, client adapters, and documentation to reflect this simplification.
BREAKING CHANGE: "none" is no longer a valid COMPUTE_MODE; only "local" and "worker" are supported. "unsupported" parse status and PDF margin settings are removed.
Implement block-level highlighting in PDF viewer by leveraging parsed document
structure and TTS segment locator. Extend highlightPattern API to accept options
for parsedDocument, locator, and block geometry mode. Update PDFViewer to use
block geometry highlighting when available, improving accuracy and alignment of
sentence and word highlights with ONNX-based DocLayoutV3 parsing. Refactor
highlighting logic to support both legacy span-based and new geometry-based
approaches.
Migrate PDF parsing to use ONNX Docling layout model for structured block extraction, enabling improved TTS segmentation and chaptering. Add compute backend abstraction for heavy tasks (alignment, layout parsing) with configuration via `OPENREADER_COMPUTE_MODE`. Integrate block-level locators and document settings for per-document PDF parsing options. Update S3 storage for parsed PDF JSON, add migration and schema changes, and extend client and server APIs for parsed data and settings. Remove legacy word highlight flag in favor of compute capability detection.
- Add ONNX model download, local/none compute modes, and `onnxruntime-node` dependency
- Update PDF viewer and TTS pipeline to use parsed blocks and block-level locators
- Add document settings storage and APIs for per-document PDF options
- Update S3 storage layout for parsed PDF JSON
- Add admin/config/docs updates for new compute and parsing features
- Remove obsolete word highlight runtime flag and UI
BREAKING CHANGE: PDF parsing and word highlighting now require `OPENREADER_COMPUTE_MODE=local` and ONNX model; document settings and S3 layout updated; legacy word highlight flag removed.
