-# [S] moq-mux exports the per-source clock anchor
-
-## Goal
-
-An application running its own demuxer puts several tracks of one source on
-the broadcast `Clock` with one shared offset, as the built-in TS, fMP4, and
-FLV importers do, without going through a built-in importer.
-
-## Plan
-
-Requested by an external consumer (OneTooMany, Discord): their MPEG-TS
-ingest publishes video, KLV, and sometimes audio from one program. One
-`SourceMap` per track lets tracks drift apart by their first-PTS difference,
-and one shared `SourceMap` reads interleave (beyond `MAX_REORDER`) as a reset.
-
-Decided: make `clock::Anchor` and `clock::Lane` public with the API the
-importers already use: `Anchor::new(clock)`, `translate(&mut lane, pts)`,
-`translate_at`, `extend`, and `Lane::restart`, with `Lane: Default`. Additive,
-so it lands on `main` for a 0.10 patch.
-
-Open for the PR: the export path. Proposal: `pub mod clock` with
-`moq_mux::clock::{Anchor, Lane}`, keeping the root `Clock` re-export. Ask the
-maintainer with alternatives.
-
-Document both in `doc/lib/rs/moq-mux.md`, with a two-track example.
-
-Their other `ts::Import` gaps (MPEG-2 video, KLV reassembly) stay unplanned
-until requested directly. The H.265 per-packet error is
