samiandClaude Sonnet 5 3db0d01f9d daemon: download.add / download.list / download.get behind the store
VeloxDispatcher now takes a store::Db& and three handlers are real:

- download.list -> store::Tasks::list (filter / sort / paging in SQL) ->
  to_summary per row. No more empty-table stub.
- download.add -> resolve saveDir (spec, else saveTo.defaultDir; ~ expanded)
  and the leaf (spec.filename, else the URL's last segment percent-decoded,
  else download.bin) -> fs::resolve_target against canonicalize_root'd
  saveTo.allowedRoots. Any path-destination failure is -32011 with the
  *original* saveDir in data.path. On success a TaskRow is inserted in
  state `queued` (or `new` for startMode "manual") and {taskId, state}
  returned. The scheduler that would then admit it is D4.
- download.get -> store::Tasks::get; a real -32010 + data.taskId for an
  unknown id, else a TaskDetail (segmentDetail empty until the engine
  segments the task, which the schema permits).

util/time.hpp: now_iso() factored out of ws_server.cpp.

main.cpp constructs the dispatcher with the opened db. The three
integration tests build an in-memory migrated db for it; velox.client
now drives the full slice through the CLI — add outside roots -> -32011
with data.path, add into an allowed root -> a task that download.list
shows and download.get details, unknown id -> -32010. Verified with the
real binaries: velox add persists, velox ls shows it, it survives a
daemon restart, /etc is refused.

ASan+UBSan and TSan clean; 34 daemon/cli tests green. deferrals.md:
D2 down to just download.probe; D3 down to categories/queues/rules/
settings/limiter/schedule.

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 M0M7, 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.

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.
