Roadmap phase 6, first half.

API

GET /api/storage (needs a session): for each disk of PLANKTON_DISKS, path, available, total_bytes (statvfs f_blocks × f_frsize), free_bytes, reserve_bytes (PLANKTON_MIN_FREE_GB), usable_bytes, pending_bytes (what the session's unfinished torrents on that disk will still write) and room_bytes (usable − pending), plus totals over the available disks. Read under add_lock.

The room computation is now one function, downloads::disk_rooms, shared by the disk choice of POST /api/downloads, the room check of PATCH and this route. DiskStatus gains total_bytes and reserve_bytes (so /health shows them too). A disk with more pending than usable now has a room of 0 instead of being skipped: same outcome for any real download.

Web

  • Navbar: disk <room> free (sum of the room over the disks, mono 11px), each disk in the tooltip, a warning when a disk is missing. Polled every 30 s, and refreshed after a download is added or removed and when metadata loads.
  • Magnet action bar: the mockup's DISK bar for the disk the selection would go to (the one with the most room, as the server picks), named in the tooltip. Used (everything a new download cannot use: files, reserve, pending) + selection (accent, or error when it does not fit), animated width, used · + selection · X free after / X short below. Start is disabled with "Not enough space: deselect X or free some disk." when it does not fit. The "filed into" path moved under the library select.

Checks

cargo fmt, clippy -D warnings, 129 tests (3 new for the route: two disks with a reserve, a missing disk, pending bytes after adding a torrent); svelte-check and vite build. Screenshots taken against the real backend on two scratch disks.

Docs: README API row and Storage section, ROADMAP, bruno/storage.yml.

Roadmap phase 6, first half. ## API `GET /api/storage` (needs a session): for each disk of `PLANKTON_DISKS`, `path`, `available`, `total_bytes` (statvfs f_blocks × f_frsize), `free_bytes`, `reserve_bytes` (`PLANKTON_MIN_FREE_GB`), `usable_bytes`, `pending_bytes` (what the session's unfinished torrents on that disk will still write) and `room_bytes` (usable − pending), plus `totals` over the available disks. Read under `add_lock`. The room computation is now one function, `downloads::disk_rooms`, shared by the disk choice of `POST /api/downloads`, the room check of `PATCH` and this route. `DiskStatus` gains `total_bytes` and `reserve_bytes` (so `/health` shows them too). A disk with more pending than usable now has a room of 0 instead of being skipped: same outcome for any real download. ## Web - Navbar: `disk <room> free` (sum of the room over the disks, mono 11px), each disk in the tooltip, a warning when a disk is missing. Polled every 30 s, and refreshed after a download is added or removed and when metadata loads. - Magnet action bar: the mockup's DISK bar for the disk the selection would go to (the one with the most room, as the server picks), named in the tooltip.

Start is disabled with "Not enough space: deselect X or free some disk." when it does not fit. The "filed into" path moved under the library select. ## Checks cargo fmt, clippy `-D warnings`, 129 tests (3 new for the route: two disks with a reserve, a missing disk, pending bytes after adding a torrent); svelte-check and vite build.

GET /api/storage gives, for each disk, its size, free space, reserve,
what the unfinished downloads will still write there and the room left
for a new one, plus totals over the available disks. The room comes
from the same function the disk choice of POST /api/downloads uses.

The navbar shows the room left over all disks, with each disk in its
tooltip, refreshed every 30 s and after a download is added or removed.
The Magnet screen's action bar shows the disk the selection would go to,
and blocks the start when it does not fit.
