  "description": "Golden fixture. tests/conformance replays this against the real daemon AND the TS client. If either side drifts, this goes red before the lanes ever integrate. url is example.org (RFC 2606), not a real download source: 'take' against a real veloxd (tests/conformance/run.sh) admits a real task and hands it to the engine for real, and no fixture may do that against a real external URL. contentLength is a plausible-but-small 5 MiB rather than a real ISO's size: the 'Programs' category's saveDir is a migration-seeded builtin (~/Downloads/Programs, daemon/src/store/migrations/0001_initial.sql), not something an isolated test run's settings can redirect, so 'take' always sparse-preallocates into that real path on whatever machine runs this suite -- keeping the declared size small keeps that footprint trivial instead of a real ISO's worth of disk. transport is uds only: a real 'take' persists an active task, so replaying this same fixture again on a second live transport against the same daemon would correctly dedupe against it (capture.offer dedupes by exact URL) and get 'ignore' instead -- an artifact of replaying one fixture against one shared daemon over two transports, not a behaviour to golden.",
