[features]
# No features. The `parse` module (gemtext/gopher/nex/feed) compiles
# unconditionally: the dep-free parsers cost nothing, and the feed parser's
# quick-xml is light enough to keep as a plain dependency rather than a gate. (A
# cargo feature added in a sibling repo is invisible to its dependents until the
# crate is pushed, which made a `parse-feed` gate impractical in this workspace.)

# The Guppy protocol transaction (spec v0.4.4: acks, retransmission, chunk
# reassembly) lives in its own spec-faithful crate; errand adapts its response.

# 2026-07-10 with errand), each keeping its own published crate identity.

# RSS / Atom feed parsing (`parse::feed`). A light pure-Rust XML reader; kept an

# impractical, and quick-xml is small relative to the rustls/tokio cone).

# Host-neutral tracing facade: errand only *emits* structured events on the
# load-bearing fetch op; the consuming app installs the subscriber. No dep on any
# app or diagnostics registry.
