Update DocumentUploader to upload all accepted files without filtering by type,
enabling consistent handling of DOCX and other supported formats. Add a default
timeout for DOCX-to-PDF conversion to prevent hanging LibreOffice processes.
This improves reliability and ensures uploads do not silently stall.
Remove the separate docx-to-pdf upload API and integrate DOCX conversion directly into the blob upload finalize route. Update client and uploader logic to treat DOCX as a supported upload type and streamline batch state handling. Adjust document caching and test helpers to align with the new unified flow. Add server-side DOCX-to-PDF conversion utility and corresponding unit tests.
This change simplifies the upload pipeline, consolidates conversion logic, and improves maintainability.
Avoid enqueuing duplicate parse jobs for PDFs that are already parsed or in terminal states. Update docx-to-pdf upload to reuse existing parsed PDF results when possible, skipping unnecessary parse operations and job enqueuing. Adjust parse-state-backfill to only enqueue jobs for pending or running states. Refine client upload logic to better infer document type from MIME when file names are missing. Enhance usePdfDocument to handle terminal parse states more robustly.
This change ensures idempotent parse job creation and reduces unnecessary worker load, while improving document upload and parse state handling.
Introduce startPdfParseOperation to encapsulate worker operation creation, job rate tracking, and parse state initialization for PDFs. Replace scattered operation setup logic in register-upload, docx-to-pdf upload, and parse-state-backfill with this unified helper. Update job enqueuing to propagate initial opId/jobId/status for accurate state tracking.
Change getParsedPdfDocument to throw on non-ready states and remove polling logic from usePdfDocument, shifting readiness detection to event streams. Switch API responses for non-ready parses from 202 to 409 to clarify client expectations and simplify error handling.
Add targeted tests to verify legacy backfill behavior and ensure no worker operation is created for pure data fetches of pending legacy PDFs.
BREAKING CHANGE: API now returns 409 Conflict for non-ready parsed PDFs instead of 202, and clients must subscribe to event streams for parse progress.
Add detection for precondition failures during blob copy to prevent race conditions when finalizing uploads. Refactor upload finalization to use Promise.all for concurrent processing. Extract parse state and parsed JSON key logic to variables for clarity and to avoid duplication in document registration.
Transition document upload flow to use presigned token-based temporary uploads. Add finalize endpoint to register uploaded documents after blob transfer, decoupling document ID assignment from upload initiation. Update client and server logic to operate on tokens, improve security, and enable canonical ID reuse for identical uploads. Update tests to verify deduplication behavior.
Add PDF_PARSER_VERSION constant and propagate parser versioning throughout
the PDF parsing, job, and API layers. Implement normalization of parse state
to ensure compatibility with the current parser version, and enable reuse of
parsed PDF results when possible. Add isPlaybackReady state to document hooks
and TTS player, improving playback UX by disabling controls until content is
ready. Update tests to reflect new playback readiness logic.
BREAKING CHANGE: PDF parse state and job logic now require explicit parserVersion;
older parse states may be treated as pending until reprocessed.
Eliminate the unused --delete-local option and related code from the
filesystem migration script to prevent accidental local data removal.
Introduce a cleanupClaimedLegacyFsSources utility for removing legacy
filesystem sources after claim, and integrate it into the user claim
flow. Add unit tests to verify the cleanup logic.
Introduce a backfill handler to restore missing PDF parse operations for
documents in legacy 'pending' or 'running' states lacking an opId.
Update parsed route handlers to invoke this logic, ensuring correct
operation association for affected documents. Add regression tests to
validate backfill behavior for legacy scenarios.
* refactor(ui): replace anchor tags with next/link in SidebarNavLink and UserMenu
Update SidebarNavLink to use next/link for navigation instead of anchor tags,
ensuring proper routing and improved accessibility in Next.js. Refactor UserMenu
to remove legacy Link wrappers and directly use SidebarNavLink for signin and
signup links. This streamlines navigation components and aligns with Next.js
best practices.
* fix(pdf): handle non-zero viewport origins and improve layout model ordering
Update normalizeTextItemsForLayout to correctly apply viewport transforms,
including non-zero page origins, ensuring accurate mapping of PDF text items
to top-left coordinates. Refactor runLayoutModel to implement a custom order
sequence builder for layout regions using model order logits, improving
region ordering consistency with model semantics. Update related tests to
cover viewport transform edge cases.
* refactor(pdf): improve text normalization with font ascent and vertical overlap logic
Enhance text normalization by incorporating font ascent and descent data to more accurately position glyphs, especially for decorative initials. Update merge logic to better detect line membership using vertical overlap, ensuring drop caps and overlapping glyphs are merged correctly. Extend tests to cover these layout scenarios.
* style(range): redesign slider with precision gauge and ruler ticks
Revamp the range input to feature a minimalist "precision gauge" style.
Introduce a hairline rail, ruler notches for discrete steps, and a slim
needle thumb. Add CSS variables and logic for per-instance tick sizing
and coloring. Remove bulky inline class-based styling in favor of
centralized CSS for improved maintainability and visual clarity.
* refactor(ui): modularize PDF loader and range slider visuals
Move PDF layout scan visualization and range slider styles into dedicated CSS
modules, isolating their styles from the global scope. Integrate PdfLayoutScan
component into the PDF viewer loader UI for animated parse progress. Refactor
progress bars to use a reusable progress-fill class with animated sheen effect.
Update range input to use CSS module for precision gauge styling.
* style(reader): remove grid overlay from PdfLayoutScan visualization
* refactor(api): add staleness detection for inflight worker operation states
Integrate isWorkerOperationStateStale checks into document parse API endpoints to ensure inflight worker operation states are not reused if stale. Introduce helper for staleness detection and corresponding unit tests. Enhance SSE event streaming with keepalive intervals and improve progress acknowledgment error handling.
* feat(worker): recover and fail stale in-flight pdf ops on startup
Add orphaned operation recovery logic to detect and mark stale in-flight pdf_layout jobs as failed during worker startup. Extend OperationStateStore with listOpStates for state enumeration. Update tests and documentation to cover recovery behavior and new environment variable COMPUTE_PDF_JOB_ATTEMPTS.
* refactor(worker): distinguish staleness thresholds for running and queued pdf ops
Update orphan recovery logic to apply separate timeouts for 'running' and
'queued' pdf_layout operations. Adjust tests to verify that only stale
'running' operations are failed, while stale 'queued' operations remain
untouched.
* feat(worker): extend orphan recovery to handle whisper_align ops and improve logging
Update orphan recovery to detect and fail stale 'running' whisper_align operations
in addition to pdf_layout. Refactor recovery logic to generalize staleness checks
across operation kinds and enhance log output with detailed operation info.
Expand tests to verify correct handling of both whisper_align and pdf_layout
operations in running and queued states.
* refactor(control-plane): introduce revision-based CAS for operation state updates
Add revision tracking and compare-and-set (CAS) semantics to operation state
stores, enabling atomic state transitions and preventing lost updates. Extend
the OperationStateStore interface with getOpStateRecord and compareAndSetOpState
methods. Update orchestrator and worker runtime to utilize CAS for marking
operations as failed only if the state is unchanged. Enhance in-memory,
JetStream, and test control plane implementations to support revision logic.
This change improves concurrency safety and correctness of operation state
management across distributed components.
* feat(ui): add parse failure state to PDF layout scan animation
Display a distinct "parse halted" visual state in the PDF layout scan
component and PDF viewer page when parsing fails. The loader animation
is replaced by a static, dimmed page with an alert glyph and updated
styling, ensuring users are not misled by an active animation after a
failure. CSS and component logic updated to support the new state.
* feat(worker): extract orphaned operation recovery to module with periodic sweep
Move orphaned operation recovery logic into a dedicated orphan-recovery module,
introducing a periodic sweep timer that triggers recovery every 15 seconds while
the worker is connected. Refactor runtime to delegate orphan detection and
handling to the new module, improving modularity and maintainability. Add
unit tests for orphan-recovery to ensure correctness.
* fix(ui): adjust PDF viewer layout and update parse loader description
* refactor(pdf): streamline layout model region extraction and update test coverage
- Replace custom order sequence logic with softmax-based class selection in runLayoutModel
- Remove unused sigmoid and buildOrderSequence functions
- Simplify detection loop to filter and map regions directly
- Add targeted tests for layout model extraction logic
- Update CSS animation naming for consistency
- Clarify test description and add inline comments for orphan recovery scenario
* fix(pdf): add strict validation for layout model output shapes and extend test coverage
Add explicit error handling for invalid or inconsistent pred_boxes and logits array lengths in runLayoutModel to prevent silent failures. Expand test suite to verify correct region filtering and error scenarios, ensuring only labeled regions are returned and malformed outputs are handled robustly.
Eliminate the enableDestructiveDeleteActions feature flag from runtime
configuration, admin panel, environment docs, and user settings modal.
Remove all references, toggles, and documentation for this flag. This
simplifies the runtime config and user interface by consolidating
destructive actions under account deletion only.
BREAKING CHANGE: The enableDestructiveDeleteActions runtime flag is no longer supported. Any configuration or code depending on this flag must be updated.
Move origin extraction to shared utility for consistent validation across
server and client modules. Update layout metadata to use the shared origin
helper, improving maintainability and deployment flexibility. Add unit tests
for layout metadata to ensure correct origin handling.
Eliminate the unused authEnabled property from context providers, hooks,
components, and API responses. All logic and UI now assume authentication is
required, simplifying prop signatures and reducing branching. Update related
types, context values, and function calls to reflect this change. This streamlines
the authentication flow and removes unnecessary configuration.
Eliminate all code, tests, and utilities related to the legacy 'unclaimed' user
scope. All API endpoints, document and audiobook storage, and access logic now
require a valid authenticated userId and only operate on resources owned by that
user. Remove related helper functions, test cases, and conditional flows for
anonymous/unclaimed data. Update types, client APIs, and UI logic to reflect
that only 'user' scope is supported. This simplifies ownership checks and
removes ambiguity around document and audiobook access.
Eliminate all code paths, configuration, and documentation related to running
without authentication. Require AUTH_SECRET and BASE_URL at startup, updating
middleware, server logic, and runtime checks to assume auth is always enabled.
Simplify onboarding, settings, and test helpers to reflect mandatory auth.
Update environment examples, Docker and deployment docs, and CI/test configs.
Remove no-auth-specific UI flows, test cases, and feature toggles.
Remove all references to legacy RUNTIME_SEED_* environment variables from documentation and codebase. Update docs and .env.example to document the new RUNTIME_SEED_JSON and RUNTIME_SEED_JSON_PATH variables for first-boot runtime config and provider seeding. Refactor admin seed logic and runtime config schema to eliminate env-var-based seeding in favor of JSON-based initialization. Update admin panel UI and badges to reflect new seed sources. Remove obsolete env parsing logic and tests for RUNTIME_SEED_* flags. Add new tests for JSON seed behavior.
BREAKING CHANGE: RUNTIME_SEED_* environment variables are no longer supported; use RUNTIME_SEED_JSON or RUNTIME_SEED_JSON_PATH for first-boot runtime config and provider seeding.
Remove TTS cache and upstream tuning environment variables in favor of admin-managed
runtime settings. Add new admin panel controls for TTS retry attempts, upstream timeout,
audio cache size, and cache TTL. Update API routes and TTS generation logic to consume
these runtime-configurable values, enabling live adjustment without redeploy. Update
documentation to reflect the removal of related env vars and the new admin workflow.
- Stream request body in blob upload fallback route to enforce size limits
without buffering entire payload
- Enhance admin provider panel error handling for multi-status responses

- Use full rate limit config for job event recording and prune by largest window
- Fix PDF layout job event userId usage in docx-to-pdf upload route
- Add missing windows array fallback in documents register route
- Minor CI workflow and env example corrections
- Update audiobooks blobstore test to use beforeAll directly
These changes improve efficiency, correctness, and maintainability across API, admin, rate limiting, and test modules.
change RUNTIME_SEED_DISABLE_COMPUTE_LIMIT default to true in env example,
documentation, and runtime config schema to align with TTS rate limit behavior.
clarify admin panel as the source of truth for enabling PDF parsing rate limits.
implement a generic user_job_events table for tracking compute job creation
enforce configurable burst and sustained limits for PDF layout parsing
add admin panel controls for compute rate limiting and max upload size
update API routes to apply and record rate checks for PDF parse jobs
document new environment variables and admin settings for compute limits
improve IP extraction logic for rate limiting accuracy
add tests for request IP extraction and test namespace gating
This change introduces a robust mechanism to throttle expensive compute operations, such as PDF parsing, on a per-user basis. It provides both burst and sustained rate controls, with admin-tunable parameters and clear user feedback on throttling. The job event ledger enables accurate concurrency and rate enforcement, while new documentation and tests ensure maintainability and clarity.
- Remove legacy TTS rate limit environment variables and migrate all related configuration to runtime settings managed via the Admin UI
- Add runtime config keys for TTS rate limiting enable/disable and per-user/IP daily quotas
- Refactor rate limiter and API routes to use runtime config for thresholds and enablement
- Update AdminFeaturesPanel to allow editing TTS rate limiting and quota values in the UI
- Add shared-provider-selection utility for consistent provider selection logic
- Update documentation to reflect new runtime/admin configuration and remove obsolete env var docs
- Add unit tests for rate limit runtime settings and provider selection
BREAKING CHANGE: TTS rate limiting is now controlled via Admin → Site features; environment variables for TTS rate limiting are no longer supported and will be ignored.
Introduce per-page progress events for PDF parsing by adding onPageStarted
hooks throughout the compute worker and core PDF pipeline. Add
compute/worker/src/pdf-progress.ts to encapsulate progress event builders.
Update server logic to emit page start and page parsed events, improving
client feedback during long-running PDF jobs.
Add src/lib/server/compute/abort-like-error.ts and integrate isAbortLikeError
to robustly detect and suppress expected aborts in API event streaming.
Update API route to ignore abort-like errors on worker proxy crash.
Add unit tests for abort-like error detection and PDF progress event
generation. Refactor PDF parse logic to allow empty merged regions without
throwing, ensuring downstream flows remain resilient to edge cases.
These changes improve observability, error handling, and reliability for
document parsing and event streaming.
Eliminate the errorCode property from server logger calls, error contract types, and API error bodies throughout the codebase. This reduces duplication and streamlines error reporting, relying on structured event names and error classes for identification. All affected API routes, server logic, and logging utilities have been updated for consistency. Documentation directory added for future reference.
Introduce `serverLogger` utility based on pino for consistent, structured logging across all server and API modules. Replace direct console logging with `serverLogger` and add request-scoped logging helpers. Update environment variable handling, documentation, and deployment guides to reflect new logging configuration (`LOG_FORMAT`, `LOG_LEVEL`, `COMPUTE_LOG_LEVEL`). Enforce no-console in server code via ESLint and add pino/pino-pretty dependencies.
This change standardizes log output, improves observability, and prepares the codebase for ingestion by log platforms.
Integrate opId handling throughout PDF layout parsing by updating client hooks, API routes, and event streams to support operation ID propagation. Add server utility for worker operation creation to centralize opId management. Enhance polling and SSE subscription utilities to accept and return opId, improving traceability and coordination of parse operations across the client and server.
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.
Add worker operation state polling to document parse routes, enabling real-time
status and progress updates from the ONNX layout worker. Introduce
`fetchWorkerOperationState` utility and status mapping logic to synchronize
parse status with worker job state, improving accuracy for pending, running,
and failed operations.
Move shared type contracts from `contracts` to new `api-contracts` module in `compute/core` for clearer API boundaries. Remove legacy `contracts`, `pdf`, and `whisper` index files. Update all imports to use `api-contracts`. Refactor server job logic by replacing `parsePdfJob.ts` with modular `user-pdf-layout-job.ts` and `user-whisper-align-job.ts`, updating all relevant API routes and compute integration. This improves maintainability and separation of concerns across compute and server layers.
Move TTS segment cache invalidation to a fire-and-forget promise after
document update to prevent cache errors from blocking parse readiness.
Log warnings for both cache invalidation failures and warnings, but do not
interrupt the main job flow. This improves job robustness and avoids
unnecessary failures due to cache issues.
Move and re-export all PDF parsing and TTS-related types from
@openreader/compute-core/types, eliminating local type duplication.
Update imports throughout the codebase to use the new centralized type
module. Remove obsolete worker-contract file and update tsconfig paths
and compute-core exports for the new types entry point. Refactor API
routes and job logic to use the new type imports and shared parse-state
healing utility. This streamlines type management and improves
consistency between compute and app layers.
Introduce automatic healing for stale PDF parse states in API routes. Add
`isDocumentParseStateStale` utility and use a shared `COMPUTE_OP_STALE_MS`
environment variable (with config getter) to control the stale window for both
worker op replacement and app-side parse-state healing. Update documentation and
environment variable references to reflect new config.
Enables automatic marking of stuck parses as failed, improving reliability and
retry behavior in distributed compute environments.
