Closes a bounded, high-value slice of the remaining D3 stubs. settings.*/rules.*/ limiter.*/schedule.*/grabber.*/media.*/capture.*/queue.reorder/download.refreshUrl/ download.update stay deferred — reasons noted individually in deferrals.md (settings.* specifically: a real, large field<->key<->JSON-type mapping table across ~43 fields / ~50 SettingKeys, not started rather than rushed). category.upsert/remove: store/categories.hpp gains get/upsert/remove. upsert generates an id when absent and always ignores the payload's `builtin` (preserved from the existing row on replace, false on create); saveDir goes through the same fs::resolve_target canonicalize-and-root-check as download.add. remove refuses a builtin at both layers (dispatcher's -32602 pre-check; the store's own "DELETE ... AND builtin = 0" as defense in depth) and reassigns member tasks to reassignTo (default "general") inside one transaction before deleting the row. queue.upsert: store/queues.hpp gains get/upsert (set_state already existed from D4b). Same create-generates-id pattern; a create always starts 'stopped', a replace keeps the queue's current run state (upsert edits config, not run state — that's queue.start/stop). Also fixed in passing: on_complete has been a real column since migration 0001 but Queues::list/get never projected it onto Queue.onComplete. download.remove: cancels with discard_partial=true (always drops the .veloxpart pair — unlike download.cancel, which keeps them, the row is gone either way), deletes the finished file only when deleteFile is true and the task was complete (best-effort), deletes the row (segments cascade via the FK), and publishes event.task.removed (closing the last open note under D5). download.addBatch: on_download_add's body is now a shared add_one(), called once per item after merging each item's unset fields against params.defaults. download.provideAuth: forwards to EnginePort::provide_auth via a new TaskActionPort::provide_auth. `remember`/persisting to the Secret Service is accepted but not acted on — nothing in this build talks to libsecret yet. Verified against real veloxd + tools/testserver: category create/replace/ remove-with-reassignment, queue create/replace-keeps-run-state, a batch add sharing defaults.saveDir, and download.remove with deleteFile actually deleting the file and the task then 404ing download.get with -32010.

Velox Download Manager (VDM)
An IDM-class download manager for Ubuntu 26.04 LTS: multi-segment accelerated HTTP(S) downloading, resume, categories and automatic file distribution, queues and scheduler, speed limiter, a Firefox extension that captures downloads automatically, and clipboard link capture.
Name is a placeholder. Binaries are
veloxd,velox-gui,velox,velox-nmhost. Rename before first release if you want something else — do it in M0, never later.
Status
Phase M0 — scaffolding. No implementation code exists yet. This repository currently contains the architecture, the wire contract, the roadmap, and one brief per build lane so that several agents can work in parallel without colliding.
Start here:
| Document | What it answers |
|---|---|
| docs/01-architecture.md | Process model, why four binaries, framework choices and why |
| docs/02-roadmap.md | Milestones M0–M7, what runs in parallel, exit gates |
| docs/03-gui-spec.md | IDM-parity UI: every window, dialog, column, menu |
| docs/04-engine-design.md | Segmentation, resume, buffers, rate limiting, disk I/O |
| docs/05-extension-spec.md | Firefox capture, transports, pairing, media grabber |
| docs/06-risks-and-spikes.md | Snap Firefox, Wayland clipboard, and the other landmines |
| docs/07-packaging.md | .deb/PPA, Flatpak, AMO signing, install layout |
| contracts/README.md | The interface. Both sides build against this |
| CLAUDE.md | Rules of engagement for agents working in this repo |
Per-lane briefs live in docs/agents/ — one per agent, each with an owned directory list, a definition of done, and the files it must never touch. To dispatch the agents, use docs/agents/PROMPTS.md — six copy-paste prompts plus the worktree commands and the wave order.

SQLite + sparse files
The daemon owns all state and all sockets. The GUI is a view — closing it does not stop a download. The extension never touches the disk; it hands URL + headers + cookies to the daemon and gets a task id back.

Toolchain bootstrap
Surveyed on this machine 2026-09-09 — most of it is already installed:
| Present | Version |
|---|---|
| git · cmake · ninja · g++ · gdb | 2.53.0 · 4.2.3 · — · 15.2.0 (C++23 ready) |
| qt6-base-dev · qt6-tools-dev · qt6-tools-dev-tools | ✓ |
| libcurl4-openssl-dev · libsqlite3-dev · nlohmann-json3-dev · libssl-dev | ✓ |
| libavformat-dev · libavcodec-dev · ffmpeg | ✓ |
| clang-format · clang-tidy · python3 · pkg-config | ✓ |
| python3-jsonschema · python3-referencing (conformance static runner) | ✓ |
Only these four are missing:
sudo apt update && sudo apt install -y \
qt6-svg-dev \ # GUI: SVG icon rendering
libsecret-1-dev \ # DAEMON: Secret Service for site logins
nodejs npm \ # EXT + PROTO: extension build, mockd, conformance runner
clang # optional: libFuzzer targets in M7
Node in the 26.04 archive may lag; if the extension toolchain needs 22+, use nvm.
Verify with cmake --preset dev && cmake --build --preset dev once lane CORE lands its
first target. Note CMake 4.2.3 is installed — newer than the 3.28 floor in
CMakeLists.txt, and it hard-errors on cmake_minimum_required below 3.5, so no
dependency may ship a pre-3.5 CMake file.
