[release] v9.1.0 lockstep + independent crate releases (transmux 0.21, media-doctor 0.6, multimux 0.5.1, ll-hls-runtime 0.3, rtmp-runtime 0.3, ttml-subtitle 0.1) - #854

- Lockstep six (broadcast-common, dvb-si, dvb-t2mi, dvb-bbframe, dvb-conformance, dvb-tools): 9.0.0 → 9.1.0 (dvb-conformance T-STD buffer model + indicators 3.3/3.9/3.10; others lockstep-only). - transmux: 0.20.0 → 0.21.0 (InputDegradation events, constant_iv_senc on EncryptConfig, non_exhaustive sweep). - multimux: 0.5.0 → 0.5.1 (DASH/LL-DASH 503 fix, defensive StreamType filtering, LlHlsBody defensive match). Non-breaking: DriverProgress is a public struct with all-private fields, so adding a private track_generations field is not breaking. - media-doctor: 0.5.0 → 0.6.0 (non_exhaustive Cli, HLS+DASH validators). - ll-hls-runtime: 0.2.0 → 0.3.0 (non_exhaustive LlHlsRequest/LlHlsBody). - media-plane: 0.1.0 → 0.1.1 (drift-guard test only). - rtmp-runtime: 0.2.0 → 0.3.0 (non_exhaustive LimitType/Fmt/MessageHeader). - timed-metadata: 0.4.1 → 0.4.2 (drift-guard test + example dedup). - ts-fix: 0.4.0 → 0.4.1 (drift-guard test only). - dvb-flute: 0.3.0 → 0.3.1 (drift-guard test only). - ttml-subtitle 0.1.0: new release lane (release-ttml-subtitle.yml). - dvb-si-py 0.2.0, transmux-py 0.2.0: version bumps tracking parents. - acap-multimux: transmux pin 0.20 → 0.21. - Inter-crate dep refs updated (ll-hls-runtime ^0.3 in multimux, rtmp-runtime ^0.3 in multimux, media-doctor ^0.6 in transmux). - Cargo.lock regenerated. - CHANGELOG [Unreleased] cut to dated headings in every crate. - Release notes for v9.1.0, transmux 0.21.0, media-doctor 0.6.0, ll-hls-runtime 0.3.0, rtmp-runtime 0.3.0, ttml-subtitle 0.1.0. - ttml-subtitle added to workspace README crate table. 💘 Generated with Crush Assisted-by: Crush:deepseek-v4-pro
…de taxonomy, missing notes, README coverage - Revert the out-of-workspace bumps (acap-multimux, dvb-si-py, transmux-py). They take transmux from crates.io by version, so bumping them to ^0.21 before the publish makes their CI unsatisfiable. Recorded as a post-publish follow-up whose green CI is the proof the publish worked. - Correct media-doctor facts against the code: check_dash_mpd() not check_dash_manifest(), 6 DASH rules not 9, 8 HLS rules (3 LL-HLS-specific) not 5. Fixed in v9.1.0.md, media-doctor-0.6.0.md and media-doctor/README.md. - Quote the dep-consistency tool's actual six violations instead of asserting a count: four transmux ^0.20 normal-deps plus multimux's ll-hls-runtime ^0.2 and rtmp-runtime ^0.2. - Replace the flat 16-crate bump table with a cascade taxonomy carrying a why column: only four crates cascade from transmux; rtmp-runtime and timed-metadata hold it as a dev-dep, ts-fix and dvb-flute not at all. - Add the cargo tree -i / cargo tree -d mixed-version diagnostic to v9.1.0.md and transmux-0.21.0.md (issue #824, documented rather than guarded). broadcast-common 9.1 does NOT split a graph — ^9.0 accepts it; transmux 0.21 is the crate that does, and the note now says so. - Add per-crate release notes for multimux 0.5.1, media-plane 0.1.1, timed-metadata 0.4.2, ts-fix 0.4.1, dvb-flute 0.3.1. - Add the missing rtmp-runtime row to the root README crate table.

Summary
Sign-off checklist
Per-crate version table
Multimux breaking analysis
DriverProgress(multimux/src/source/mod.rs:314) is a public struct with all fields private (published,segmenters,track_generations). It uses#[derive(Default)]and exposes onlypub fn new() -> Self. No external caller can construct it with struct-literal syntax. Adding a privatetrack_generationsfield is not a breaking change. multimux → 0.5.1 (patch).Cascade table (verified against live crates.io)
Live transmux max version: 0.20.0 (verified via crates.io API)
tools/check-published-dep-consistency.pyfound 4 normal-dep violations — all resolved in this PR:Also: multimux 0.5.0 required ll-hls-runtime ^0.2 (bumped to ^0.3) and rtmp-runtime ^0.2 (bumped to ^0.3).
3 stale dev-deps (mpeg-ts→mp4-emsg, rtmp-runtime→transmux, transmux→media-doctor) are hygiene-only — old majors still published and consumers never pull dev-deps.

All four are met.
