Problem

Three decisions the maintainer made on 2026-10-24 need moq quests:

• adopting pure-Rust crypto for moq-relay, from the spike in kixelated/rust2#13;
• fixing a C name clash in moq-ffi's generated header;
• re-running the per-layer crate split decision from #5460, now that kixelated/rust2#21 supports same-named types across crates in every generator.

Approach

• New m2 epic, Pure-Rust crypto for moq-relay, with three quests:
  1. JWT on graviola [M]: a graviola-based jsonwebtoken provider in moq-auth. This drops the rsa crate's Marvin exposure (RUSTSEC-2023-0071) and the duplicate RustCrypto generation.
  2. moq-relay on graviola [L]: graviola for the x86_64/aarch64 release targets and aws-lc-rs elsewhere. moq-tokio refuses both providers at once, and CI builds moq-relay alone. The QUIC adapter stays until ctz/graviola#156 ships. The ChaCha20 slowdown is accepted and recorded.
  3. Provider-neutral rustls-acme upstream [S]: moq carries the spike's patched copy until this lands. Posting upstream needs the maintainer's approval when it starts.
• One C name per moq-ffi item [S], first in the C bindings epic. MoqAudioEncoder::finish and MoqAudioEncoderFinish both map to moq_audio_encoder_finish. Rust2's C generator derives collision-free names (for example, qualifying with the type) instead of a rename in moq-ffi. The work lands in rust2's fork, and this quest stands in until the fork ships it.
• m2 Re-run the per-layer crate split decision [S], next to the switch to rust2's UniFFI.

moq-relay on graviola Requires JWT on graviola, so the spike's interim rust_crypto JWT backend never ships the rsa crate.

Impact

None; quest files only. Wire: none.

Alternatives

The crypto work could be one quest. The maintainer chose an epic so the relay can move while the rustls-acme change waits upstream.

Follow-ups

rust2's side (the benchmark's no-C check, the MIR spike, and the rest) is in its own PR: kixelated/rust2#29.

Decisions

• JWT before the relay: ✅ Keep JWT first (relay-graviola requires jwt-graviola) / Land independently
• C name clash: ✅ Fix the C generator (collision-free names) / Rename in moq-ffi
• Crypto Fix for audio breaking after a certain time into the stream #13: ✅ Adopt, all 7 recs / Keep measuring / Drop it
• moq crypto split: ✅ Epic, 3 quests / One quest
• UniFFI: ✅ Drop C++ dead modes, ✅ C name clash, ✅ moq crate split rerun / Namespace edge cases
• Build: ✅ No-C check / Early cutoff upstream / moq-net split

The maintainer approved merging on 2026-10-24.

Walkthrough

The changes add planning documents and required-quest entries for a C-name collision in moq-ffi, reassessing its UniFFI crate split, and using graviola and RustCrypto for C-free moq-relay release builds. The documents record proposed approaches, constraints, performance measurements, and follow-up work. They do not change implementation code.

Priority: Low

Merge Risk: Low · up to 4af4c

The planning quests need clearer release boundaries and packaging constraints, but the PR changes documentation only and remains mergeable with bounded follow-up.

Pre-merge checks: 5

Inline comments:
Review comments at @quest/m1/c/name-clash.md:
- Around line 16-17: Update the Public API impact line in the name-clash quest
to state that renaming an exported moq-ffi item changes its generated name
across all bindings, not only C, and distinguish that from the generator’s
C-name changes; keep the Wire impact as none.

Review comments at @quest/m2/ffi-crate-split.md:
- Around line 14-15: Update the ffi-crate split discussion around rust2#21 and
the #5460 harness to state that Swift supports same-named types only with one
module per crate, while the xcframework path combines crates into one module;
specify the supported Swift packaging path or make the split conditional on
changing the xcframework path.

Review comments at @quest/m2/pure-crypto/relay-graviola.md:
- Around line 7-8: Update the dependency-check instructions in the Goal section
to specify running cargo tree -i for each forbidden package and each release
target, naming the corresponding release triple so the aarch64 dependency graph
is checked even on an x86_64 host.

Merging with the maintainer's approval (2026-10-24), which also settled the two open calls: JWT on graviola lands before the relay, and the C name clash is fixed in rust2's C generator, not with a rename in moq-ffi.

• New m2 epic pure-crypto/ (JWT on graviola, moq-relay on graviola, provider-neutral rustls-acme upstream), m1/c/name-clash.md, and m2/ffi-crate-split.md.
• Checks: just ci passes (markdown lint included), quest check --base origin/main --branch plan/pure-crypto-followups passes from outside the head, CodeQL passes, and Codex had no findings on 61f90e0. CodeRabbit's three findings are fixed and replied to.
