refactor(stats): one name per stats track, reader, and CLI surface - #6472
Conversation
Quest-Claim: 050ce8efe91db634
Rename the prefix track to <path>/prefix.json, take an Encoding instead of a compressed bool, name the consume readers *Consumer like the aggregate ones, rename the CLI media report surfaces to import --report and export report, drop the relay --stats-* flags from moq, and make stats.interval a duration.

Retain --stats as a hidden deprecated flag.
The rename removes --stats without adding a hidden legacy field or reporting it from Import::deprecated(). The old spelling is rejected as an unknown flag before the startup deprecation error can name --report. Add the hidden field and a deprecated() entry. The previous declaration had no explicit environment binding, so preserve that behavior.

Carries #6472's renames onto the group tracks: Encoding for track names, consume::GroupConsumer, and the FRAME_TOO_LARGE wording. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Completes
quest/m1/api-audit/stats-naming.md: each moq-stats track and reader has one name, the encoding is a type, and "stats" means one thing in the CLI.Changes
<path>/traffic.jsonis now<path>/prefix.json, soprefix_track()no longer shares a word withtraffic_track()(publisher.json/subscriber.json).Encoding { Plain, Compressed }replaces thecompressed: boolon the five*_trackfunctions and thecompression: bool/with_compressiononconsume::Configandaggregate::Config(nowencoding/with_encoding).COMPRESSED_SUFFIXstays public for name parsing. The producer's internals use it too, which folds three copies of the plain/compressed slot match intoPendingPair::slot.consume::{Traffic, Sessions, Totals, Presence, Prefix}shared names with the entry types (Traffic,Presence,Totals,Prefix). They are nowconsume::{TrafficConsumer, SessionsConsumer, TotalsConsumer, PresenceConsumer, PrefixConsumer}, matching the existingaggregate::*Consumer.doc/concept/stats.md: the entry heading "Sessions" is now "Presence" to match the type, the presence-track section becomes "Per-label tracks", and both too-large mentions use the wire nameFRAME_TOO_LARGE.import --statsisimport --reportandexport statsisexport report(the code isreport.rs). The--stats-*relay flags are gone frommoq: they published the relay's.stats, whichexport statscould not read. This also drops the now-dead per-session registry wiring in the listener.stats.interval/--stats-interval/MOQ_STATS_INTERVALis a duration ("1s"), and a zero interval refuses to start rather than being clamped (a zero period would panic the publish task's ticker).--stats-intervaland--stats-lingernow have--helptext.traffic.jsonand--stats/export statsare updated.Consumer of each change: moq.pro (uses
traffic_track,sessions_track,COMPRESSED_SUFFIX, and the frame types) and the CLI's own users.Public API and wire impact
*_trackfunctions takeEncoding;consume::Config/aggregate::Configtakeencoding;consumereaders renamed. MIGRATE entry added.stats::Config::intervalis aDuration,stats::Config::buildreturnsanyhow::Result, and the TOML/flag/env value is a duration string.

It was never released.Decisions
*Consumerin both modules (consume::TotalsConsumer,aggregate::TotalsConsumer). It removes the clash with the entry types (crate::Totals,Prefix,Traffic,Presence) and keeps the aggregate names that shipped. Rejected: short names in both modules (consume::Totals,aggregate::Totals), which keeps that clash.Checks
just checkpassed on the merged head (lint, docs, quest, markdown, and the Rust tests of the changed crates and their dependents).just test interop --all; the only wire change is the name of an unreleased, on-request stats track.Follow-ups
