daemon: persist engine progress/probe to the store — segments:0 no longer leaks
Engine numbers never reached the store: download.get after a correctly-finished
download reported sizeBytes: null, downloadedBytes: 0, speedBps: 0, resumable:
false, segments: 0, segmentDetail: [] — segments: 0 breaks the frozen contract
(TaskSummary.segments is minimum:1, required).
- Scheduler::tick() now probes (EnginePort::probe) before every start(), persisting
sizeBytes/resumable/validators via Tasks::set_probe_result before a byte moves,
then starts the engine with that ProbeResult as probe_hint.
- Scheduler::persist_progress() (new) writes downloadedBytes/speedBps/segments/
segmentDetail from the engine's Progress. Called from progress_snapshot() (the
250ms tick) *and* once more from on_engine_state right before release()/unmap on
every terminal transition, so a task that finishes between two ticks — the common
case for anything small or fast — still leaves real numbers instead of the
pre-persistence defaults.
- TaskSummary.segments is sourced from segments.size() when the task has any
(matching what actually lands in segmentDetail, per the schema's "exactly
segments entries"), falling back to the engine's effective_segments (budget
slots *held*, not necessarily physical range count) only pre-segmentation.
- Tasks::set_final_bytes tops up on_finished's byte count as a last-resort
backstop.
- store/segments.{cpp,hpp}: read/write access to the segments table behind
TaskDetail.segmentDetail. Wired into daemon/CMakeLists.txt.
- migrations/0002: speed_bps on tasks and segments; fixes segments.state's CHECK
to include 'pending' (0001 omitted it, so a pre-connect snapshot could never be
written).
- store_migrations_test's forward-only loop faked "released version N" by setting
the user_version pragma alone, with no real schema underneath — never exercised
until 0002 existed. Fixed to actually build the db through migrations 1..N first.
Verified against real veloxd + tools/testserver (not just unit tests):
download.list/download.get correct immediately after completion and after a
daemon restart, with saveTo.allowedRoots pointed at an isolated dir.
Observed but not fixed (CORE, not this lane, noted in deferrals.md): Progress.
speed_bps reads back 0 for the whole lifetime of a live throttled download in the
same E2E check, despite downloadedBytes visibly advancing. DAEMON passes it
through unmodified; filed rather than worked around.

daemon: store/ — SQLite WAL schema + forward-only migrator (build step 3)
The daemon's persistent state. SQLite in WAL mode, foreign keys on,
5 s busy timeout so a writer waits rather than SQLITE_BUSY under the
RPC loop.
- store/sqlite — RAII Db/Stmt over the C API; errors returned as
DbResult<T> (std::expected), never thrown — the RPC loop must not
unwind. transaction() helper: BEGIN / fn / COMMIT, ROLLBACK on error.
- store/migrations/0001_initial.sql — the eight tables from the brief:
settings, categories, queues, tasks, segments, rules, history,
pairings. Notable choices:
* tasks columns project onto proto TaskSummary with no computation;
requested vs effective segments/buffer split per ADR 0010/0012;
pause_reason column per ADR 0013.
* segments end_byte is NOT constrained >= 0 so a whole-file
zero-length download is one row with end_byte = -1 (ADR 0010 B3a).
* pairings stores only token_sha256 — the plaintext token is
returned once from session.pair and never persisted (CLAUDE.md §4).
* indices on tasks(state), (category_id), (queue_id, queue_position),
(created_at), (completed_at) for the "1000 tasks, download.list
under 50 ms" DoD.
* six built-in categories + a Main queue seeded.
- store/migrations — runs every embedded migration past PRAGMA
user_version, each in its own transaction, forward-only. SQL files
are embedded at build time by cmake/embed_migrations.cmake.
Test veloxd.store_migrations (ASan+UBSan and TSan clean): fresh DB ->
head, all tables present, seed rows, FK cascade (segment orphan
rejected, task delete cascades), the end_byte=-1 zero-length case,
idempotent re-run, and forward-only from every released user_version.
Also: daemon/docs/proto-requests-m1.md — P1 marked landed on lane/proto
as 1.4.0 (HandlerError/HandlerResult), to be adopted in rpc/ once that
merges to main; P2 resolved.
Not linked into the running daemon yet — the store is wired to the
dispatcher when download.add/list/get get real bodies, next.
