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.

veloxd is the one process that turns an untrusted string into a
filesystem destination, and via capture.offer that string can come
from a web page. CLAUDE.md §4 and the M1 DoD both name this.
daemon/docs/safepath-adversarial.md is the spec, written before the
code the way EXT did for shouldCapture: 21 rows — .. traversal
(A1/A2), absolute-outside-roots (A3), prefix-match confusion (A4),
symlink-out (A7), TOCTOU on a created tail (A8), NUL/control bytes in
the leaf that CORE's fuzzer hit through Content-Disposition (A9/A10),
degenerate and overlong leaves (A11/A13), overlong dir component
(A14), symlinked root (A16), destination-is-a-file (A17), and the
legitimate cases that must still pass — non-ASCII (A18), redundant "."
(A19), trailing space/dot trimming (A20).
fs/safepath.cpp:
- sanitize_leaf: strip <0x20 and 0x7F, trim ws, strip trailing dots,
reject ""/"."/".."/contains-'/', cap 255 UTF-8 bytes on a codepoint
boundary. Mirrors core/src/net/content_disposition.cpp.
- canonicalize_root: expand ~ and realpath each allowedRoots entry
once, so a symlinked root resolves to its target.
- resolve_target: reject relative saveDir and any ".." component
lexically; if the dir exists, realpath + component-wise containment
(a symlink that escapes is caught, one that stays inside passes); if
a tail is missing, realpath+check the deepest existing ancestor then
create the tail via an openat/mkdirat O_NOFOLLOW walk and re-derive
the final path from the fd. Every failure is -32011 with data.path =
the *original* saveDir (never the resolved path). Residual TOCTOU on
a pre-existing intermediate dir is documented and closed by CORE's
O_NOFOLLOW open of the file.
veloxd_fs static lib; veloxd_rpc links it for the download.add wiring
next. Test veloxd.safepath is the adversarial table, on a real temp
tree. ASan+UBSan and TSan clean; 33 daemon/cli tests green.

The scheduling brain, built against CORE's headers (vdm/engine.hpp,
vdm/segment/budget.hpp) — signatures only; the Engine bodies land in
CORE stage 8 and the Scheduler that wires governor <-> store <-> engine
<-> timer comes after that (daemon/docs/deferrals.md D4).
- sched/governor — a pure decision function. In: a snapshot of every
task's coarse RunState and every queue's state (schedule windows
pre-resolved). Out: {to_start, to_resume, to_pause, pause_reasons,
priority_order}. Enforces, all in TASK units per ADR 0011 §1:
connection.maxConcurrentDownloads; the min(that, maxActiveSegments)
clamp (§2); Queue.maxConcurrent; the per-host task cap (§4); and a
stopped queue / closed window runs nothing. Never touches a task
paused for `user` or CORE's `auto` (ADR 0013 §3) — only Schedule /
QueueStopped / AdmissionReconcile are auto-resumable. Deterministic:
main-list before queued-in-queue, then queue order, then FIFO, then
task_id.
- sched/schedule_window — window_open(Schedule, local tm): disabled =>
always open; `once` => date + time match; `periodic` => weekday in
daysOfWeek (empty = every day) + time in [start, stop); null start =>
midnight, null stop => end of day, stop < start => overnight window.
Pure; re-evaluated every tick, no cached instants.
- veloxd_sched static lib; veloxd links it (nothing calls it yet).
Tests (ASan+UBSan and TSan clean): veloxd.sched_window (10 window
cases incl. overnight, once, null bounds), veloxd.sched_governor
(global/clamp/per-queue/per-host caps, stop vs window pause reasons,
resume-only-governor-reasons, auth-pause untouched, admission
reconcile, determinism under shuffled input). 32 daemon/cli tests
green; full tree green.
