Schemas for the whole v1 surface: 38 methods, 9 events, 25 named types and the
JSON-RPC envelope, with x-privileged / x-transports / x-deadlineMs / x-errors
annotations that both generators emit as data rather than prose.
Four generators over one IR (contracts/codegen/schema_ir.py), so the C++ structs,
the TypeScript types and the OpenRPC document cannot disagree about what the
contract says:
gen_cpp.py -> core/generated/velox_proto.{hpp,cpp}
gen_ts.py -> extension/src/shared/protocol/
gen_openrpc.py -> contracts/openrpc.json
gen_cpp_conformance.py -> tests/conformance/cpp/fixture_dispatcher.hpp
Inbound parsing never throws: parse<T>() returns std::expected<T, ParseError> and
nlohmann's throwing ADL from_json is deliberately not emitted. Schema constraints
(minimum, maxLength, pattern, ...) become real runtime checks in both languages —
the daemon does not trust the extension and the extension does not trust the
daemon.
59 golden fixtures: a success case per method, 12 error cases, 9 events. Replayed
by tests/conformance/ against both the generated C++ and a live server over both
transports. tools/mockd serves the same fixtures with unhappy-path flags so the
GUI and EXT lanes never wait for veloxd.
run.sh also proves capture.offer fails open: with a daemon answering slower than
750 ms the client gives up and lets Firefox take the download.
core/generated/ is libveloxproto, a separate target from libveloxcore, which
still never sees JSON — see docs/adr/0009.

Zero-dependency Python 3.11+ single file. 16 failure modes selectable by
URL path and combinable with '+': no-range, lies-about-accept-ranges,
etag-changes, flaky-reset (TCP RST mid-body, clean on the 3rd try),
slow-loris, redirect-chain, 401-basic, 401-digest, 403-without-referer,
416-always, content-length-mismatch, expiring-signed-url, throttled,
chunked-no-length, utf8/legacy content-disposition. Deterministic
synthetic bodies (byte i = f(seed, path, i)) with a /sha256/ reference
route so any range is independently verifiable. /__control {"reset":true}
clears flaky-mode counters between cases.
selftest.py exercises every mode (43 checks) and is registered as the
`testserver_selftest` CTest. README documents the full surface — CORE's
M1 DoD is written against it.

Installs the full apt dependency set for a clean Ubuntu 26.04 machine
(build toolchain, Qt 6, libcurl/sqlite/openssl/secret, ffmpeg, node, lint
tools), then verifies versions: cmake >= 3.28, g++ with working
-std=c++23 <expected>, node >= 20, and every -dev package via pkg-config.
--with-clang adds LLVM for the M7 fuzz targets; --packaging adds .deb
tooling; --check verifies without installing. Flags the CMake 4.x
pre-3.5 cmake_minimum_required hazard from the brief.

Lays out Velox Download Manager (IDM-class download manager for Ubuntu
26.04) as a monorepo ready for parallel lane development. No implementation
code by design.
- docs/: architecture, roadmap M0-M7, IDM-parity GUI spec, engine design,
Firefox extension spec, risks/spikes, packaging
- contracts/: wire-contract skeleton (JSON Schema + fixture templates) —
the single synchronization point between lanes
- docs/agents/: one brief per lane (PROTO, CORE, DAEMON, GUI, EXT, PKG/QA)
with owned directories, build order and definition of done
- CLAUDE.md: rules of engagement — lane ownership, layering, non-negotiables
- CMake scaffolding with dev/tsan/release/ci presets
Two environment findings shape the design: Firefox here is the Mozilla snap
(native-messaging risk, so the extension carries a loopback-WebSocket
fallback), and Wayland forbids passive clipboard monitoring (so clipboard
capture is explicit-action-first).
