+Description: IDM-class download manager for Linux (local test build)
+ Velox is a segmented, resumable download manager for Linux: a daemon
+ (veloxd) that does the transfer work, a Qt GUI, a CLI, and a Firefox
+ extension for capture.
+ .
+ This package ships veloxd, the velox CLI, the velox-gui Qt client and
+ velox-nmhost, the Firefox native-messaging host.
+ .
+ THIS IS A LOCAL TEST BUILD, not a release: it uses a placeholder app
+ icon and has no real pairing-approval UI (see /usr/share/doc/velox, or
+ packaging/README.md in the source tree, for both limitations).

+`libveloxcore` is **static**, linked into `veloxd`, `velox` and `velox-gui` directly —
+there is no `libveloxcore.so.*` to install. A shared, versioned `libveloxcore.so.1` was
+the original plan here; the user decided against building one for now (no consumer needs
+it as a shared object yet, and it would need CORE's `core/CMakeLists.txt` to grow a
+`SOVERSION`). Revisit as a CORE-lane request if that changes — this doc was corrected in
+the same commit as the decision rather than left describing something unshipped.
+
+`velox.service` and `velox.socket` are both DAEMON's (`packaging/systemd/README.md`,
+`daemon/src/rpc/systemd_activation.cpp`) — real `sd_listen_fds()` socket activation, not a
+plain `exec`. This package installs both units verbatim and lets `dh_installsystemduser`
+(compat 13) pick them up from the install tree; see `packaging/README.md` for what that
+does and does not do at install time for an already-running session.
+
 `postinst` additionally drops per-user native-messaging manifests for the packaging formats
 that need them, and **detects whether Firefox is a snap** — if so it prints (and the GUI's
 first-run wizard shows) a one-line note that the extension will pair over loopback.

+  plain generated placeholder (flat color, a download-arrow glyph), good enough to
+  install correctly and pass `desktop-file-validate`/lintian's icon checks, and nothing
+  more. **Replace it before any real release** — and do the icon-set licence audit
+  `docs/07-packaging.md`'s release checklist asks for once real art exists (this
+  placeholder was drawn from scratch for this package, so it has no licence question of
+  its own, but it is not real Velox branding either).
+
+- **No license has been chosen for Velox's own source yet.** There is no top-level
+  `LICENSE` file in the repo. `debian/copyright` says so plainly (`License:
+  Unlicensed-TODO`) rather than inventing one — that is a real project decision, above
+  any one lane. Expect `lintian` to flag this package over it; that is lintian doing its
+  job, not a bug in this packaging, and it stays a known exception to "lintian clean"
+  until the project adopts a license. The release checklist's "Licence audit" item (Qt,
+  libcurl, SQLite, ffmpeg, icon set) is separate and still open regardless.
+
+- **Pairing has no real approval UI in this build.** `libdbus-1-dev` is not in this
+  build's `Build-Depends` (D1's GUI-dialog/desktop-notification approver needs it and
+  isn't wired up yet — `daemon/src/main.cpp` still uses `EnvAutoApprover`
+  unconditionally). That approver auto-**rejects** every pairing request unless
+  `VELOX_PAIR_AUTO=1` is set in `veloxd`'s environment — there is no prompt, no
+  accept/decline, it is all-or-nothing. `postinst` prints this prominently after
+  install; it is repeated here so it isn't missed by anyone reading only one of the two.
+  **Do not set `VELOX_PAIR_AUTO=1` on a machine or account where auto-accepting every
+  pairing request is unacceptable.**
+
+- **Socket activation is real.** `velox.service` and `velox.socket` both ship, verbatim
+  from DAEMON's `packaging/systemd/README.md` — `veloxd` receives the pre-bound fd via
+  `sd_listen_fds()` (`daemon/src/rpc/systemd_activation.cpp`) rather than binding its own
+  socket. `debian/rules` does **not** disable `dh_installsystemduser` (only the
+  system-level `dh_installsystemd`, since these are `--user` units); debhelper finds both
+  units under `lib/systemd/user/` in the install tree and enables the pair together
+  (`Also=velox.socket` in `velox.service`'s `[Install]`).
+
+- **The systemd `--user` service starts enabled for your *next* login, not this one.**
+  debhelper's `dh_installsystemduser` (verified in the built package's `postinst`) marks
+  `velox.service` enabled automatically — that takes effect the next time each user's
+  `systemd --user` instance starts. It cannot reach an *already-running* session from a
+  root maintainer script, so for the session you're in right now, `postinst` prints:
+  ```sh
+  systemctl --user daemon-reload
+  systemctl --user start velox.service
+  ```
+
+- **`dpkg -P velox` (purge) does not delete user data.** The uninstall test this package
+  is built to pass is "manifests, units and sockets removed; user data untouched *unless
+  purged*" — this build is deliberately conservative and leaves `$XDG_DATA_HOME/velox`
+  (normally `~/.local/share/velox`, the task database) alone on **both** `remove` and
+  `purge`, for every account. A root maintainer script deleting per-user data across
+  every account on the system is exactly the kind of destructive, hard-to-test operation
+  that deserves its own design pass, not a first cut bolted on here. `postrm` only ever
+  undoes what `postinst` did: the per-user native-messaging manifest it copied in.
+
+### The uninstall test, concretely
+
+What `docs/07-packaging.md`'s release checklist asks for, and what this build actually
+does:
+
+| Removed on `dpkg -r`/`-P`? | |
+|---|---|
+| `/usr/bin/{veloxd,velox,velox-gui}`, `/usr/libexec/velox/velox-nmhost` | yes — dpkg itself, ordinary package files |
+| `/usr/lib/systemd/user/{velox.service,velox.socket}` | yes — same |
+| `/usr/lib/mozilla/native-messaging-hosts/com.velox.host.json` | yes — same |
+| Per-user `~/.mozilla/native-messaging-hosts/com.velox.host.json` | yes — `postrm`, both `remove` and `purge` |
+| `$XDG_DATA_HOME/velox` (task DB, settings) | **no, on either `remove` or `purge`** — see above |
+
+### Native messaging
+
+`velox-nmhost` (DAEMON's `nmhost/`) and its manifest (DAEMON's
+`packaging/nativehost/com.velox.host.json`) now ship in this package — the top-level
+`CMakeLists.txt`'s install rules are guarded on `if(TARGET velox-nmhost)`, the same way its
+`add_subdirectory()` calls are, so this lit up automatically the day that lane merged, no
+packaging change needed on this end.
