feat(c)!: close epoch and audio query gaps - #7246
C request preparation, origin requests, and follows reported a malformed epoch differently from publication announcements, C consumers could not query audio rendition enablement, and received route hops had no C API test coverage.
Approach
Parse every epoch-taking API's text through one helper that refuses anything but canonical UUIDv7 as MOQ_ERROR_INVALID_CONFIG: moq_publication_announce, moq_broadcast_request_prepare (preserving the pending request and output handle on refusal), moq_origin_request, and moq_origin_follow (NULL or empty still means unpinned).
Add the audio counterpart to the video enabled query, reusing catalog rendition lookup. Update the API guide and C documentation.
Test snapshot enablement across disable/re-enable and continued delivery through the same consumer, error output preservation, the malformed-epoch code on request and follow, and ordered hop IDs across publisher, relay, and subscriber origins over real C sessions. The relay accepts both sessions, as a relay server does: a client session asks its peer only about what a local reader watches, which a session forwarding the relay's origin downstream is not, so a client-ingest relay never learned the route.
Extend the existing C audio fixture to call the new query through the generated moq.h and linked libmoq.a before exercising its decode consumers.
Rewrites quest/m1/c/api-gaps.md to what remains (caller timestamps for JSON windows and disabling pre-encoded simulcast rungs, added to the quest after this PR opened), and updates its link in quest/m1/c/README.md and the reference in quest/m1/api-audit/route/handle.md.
Impact
Breaking C behavior: malformed epoch text passed to moq_broadcast_request_prepare, moq_origin_request, or moq_origin_follow returns MOQ_ERROR_INVALID_CONFIG (-40), replacing MOQ_ERROR_INVALID_CODE (-15), matching moq_publication_announce. Migrate callers that match the malformed-epoch error to MOQ_ERROR_INVALID_CONFIG; signatures are unchanged.
Added C API:int32_t moq_consume_audio_enabled(uint32_t catalog, uint32_t index, bool *dst) reads enablement from that catalog snapshot, like moq_consume_video_enabled. Missing optional enablement reads as true. On failure, the destination is unchanged. Rebuild with the matching generated header and library to use it.
Wire: none. No struct layouts change.
Overlap with moq-dev/moq#7489, not yet landed, which renames the route "identity" to "instance" (maintainer's call, 2026-11-01): this PR adds no identity API and keeps main's current epoch terms. Both PRs edit doc/lib/c/index.md, and feat(net)!: routes carry an instance and a per-instance epoch #7489 will need to carry the new malformed-epoch code (MOQ_ERROR_INVALID_CONFIG) into whatever epoch-taking C functions it keeps.
moq-dev/moq#7239 removes moq-transport epochs but keeps moq-lite 07 and shared-model epochs and touches no rs/moq-c file, so these epoch APIs still apply.
Alternatives
Retaining the error-code inconsistency or exposing enablement only for video conflicts with the maintainer's settled decisions (one PR, MOQ_ERROR_INVALID_CONFIG, add the audio query, test relay hops). A dedicated epoch error would add an unnecessary code at this cut.
Choices made without asking
Reuse the existing catalog-index lookup and loopback C session harness; extend the existing C fixture rather than adding a separate consumer harness.
Extended the error-code change to moq_origin_request and moq_origin_follow (review finding), since the quest's goal is one malformed-epoch code everywhere.
Made the relay hops test's relay a server for both sessions instead of exposing relay-mode discovery to C.
Validation
cargo test -p moq-c: 164 passed (the hops test failed with the original client-ingest topology; passes 5/5 after the fix).
just rs c-tests: C fixtures and doc samples compile against the generated moq.h, link libmoq.a, and pass.
nix develop --command just ci origin/main (CI_STRICT): passes on the final head.
quest check --base origin/main passes.
On 196bbc5 (merged with main 88e6990): cargo test -p moq-c 165 passed, just rs c-tests passed, nix develop --command just ci origin/main passed, quest check --base origin/main passed.
Review
mechanical fix by codex / Codex: Merged base and mechanically adapted C-package fixtures to the timestamp and optional-epoch APIs; passed cargo fmt --all --check, cargo nextest run --locked -p moq-c --tests (166 passed), and LOCAL_SUPERVISED=1 bash sh/rs/c-tests.sh (all three C fixtures passed), with LIBCLANG_PATH set to the installed library. (head 8b72ab3)
Re-land iterate (2026-11-01), head 196bbc5: local review skipped under the simple-review rule. Since the reviewed head d641d6b, the changes are base merges plus two edits that touch only docs and tests:
the doc/lib/c/index.md conflict resolution keeps main's new demand and rendition text and the moq_consume_audio_enabled mention;
196bbc5 fixes the land failure: moq-dev/moq#7311 made moq_consume_audio take a const moq_delay *, and this PR's audio disabled test still passed a bare 10_000_000, so moq-c's test build failed (error[E0308] at rs/moq-c/src/test.rs:1018). The test now passes &TEN_SECONDS, the same 10 s budget.
Earlier rounds:
mechanical fix by codex / Codex: Merged base; re·solved quest deletion conflict by retaining newly added pending tasks and their index link. (head e2d22bb)
mechanical fix by codex / Codex: Merged base cleanly and replaced the dangling completed-quest link with plain text, preserving its requirement. (head de59b27)
Reviewer: Codex, gpt-6-astra, medium effort (quest review --deep, public API change).
Round 1 on 8dd9252: 1 finding, fixed in d641d6b: moq_origin_request/moq_origin_follow still mapped a malformed epoch to MOQ_ERROR_INVALID_CODE.
C has no way to make an origin relay-mode (eager discovery) for a client-ingest relay; a C app forwarding a client session's routes needs a local announce watcher on that origin. Worth a quest if C relays are a target.
A client session asks its peer only about what a local reader watches,
and a session forwarding the relay's origin downstream is not one, so the
relay ingest is now a server-accepted session, as on a relay server.
Deletes quest/m1/c/api-gaps.md now that validation passes.

moq_origin_request and moq_origin_follow still refused malformed epoch
text as MOQ_ERROR_INVALID_CODE. Every epoch-taking API now parses through
one helper that refuses it as MOQ_ERROR_INVALID_CONFIG.

Walkthrough
The C API adds an audio rendition enablement query and standardizes invalid epoch errors as InvalidConfig. Tests cover audio catalog snapshots, epoch validation, and relayed route metadata. Documentation updates the audio playback guidance and the listed API gaps.
Merge Risk: Low · up to 8b72a
Readers can no longer follow the direct link to the API gaps document. Restoring it is a small fix; this does not otherwise block merging.

No actionable bugs found. Sharing the epoch parser removes the error-code inconsistency without changing optional unpinned behavior or consuming a request on malformed input. The audio enablement query appropriately mirrors video and reuses catalog selection; the snapshot and relay-hop tests cover meaningful C API behavior. The breaking error-code migration is documented, and the added surface stays small.
Verification: static inspection, including an independent audio-query/refactor pass. Builds, Rust/C tests, and network tests were not run.

Reviewed changes
This run reviewed the complete diff at d641d6b4b against main, covering the rs/moq-c C ABI, its C fixture, docs, and the quest deletion.
One epoch parser.epoch_from_str now maps any non-canonical UUIDv7 text to MOQ_ERROR_INVALID_CONFIG for moq_publication_announce, moq_broadcast_request_prepare, moq_origin_request, and moq_origin_follow, replacing MOQ_ERROR_INVALID_CODE on the last three. The optional unpinned path (NULL or empty) is preserved, and moq_broadcast_request_prepare still parses the epoch before broadcast_request_take, so a refusal leaves the pending request and output handle intact.
Audio enablement query.moq_consume_audio_enabled mirrors moq_consume_video_enabled (null check and write ordering included) and reuses Consume::select::<AudioConfig>; the parallel video_enabled refactor onto select is behavior-preserving. The destination stays unchanged on error, and omitted enabled reads true via enabled_default.
Tests. The new Rust tests cover snapshot immutability across disable/re-enable through one held consumer, malformed-epoch codes on request and follow, and ordered hop ids with accumulated cost across a server-accepted relay. The C fixture exercises the new query through the generated moq.h, and Epoch::from_str makes the new bad-epoch vectors meaningful.
Docs and quest.doc/lib/c/index.md and rs/moq-c/README.md list the new query; the finished quest file and its README link are removed.
No actionable findings. The breaking error-code migration is documented in the PR Impact, and the remaining client-ingest relay limitation is recorded as a follow-up rather than papered over.
Changes: one canonical-UUIDv7 epoch parser across moq_publication_announce, moq_broadcast_request_prepare, moq_origin_request, and moq_origin_follow. A malformed epoch now returns MOQ_ERROR_INVALID_CONFIG on all four (breaking for the last three, which used to return MOQ_ERROR_INVALID_CODE). Adds moq_consume_audio_enabled, adds tests for snapshot enablement and relay hops, and deletes the finished quest.
Decisions: the maintainer accepted the extra breaking change (all four epoch-taking functions return MOQ_ERROR_INVALID_CONFIG) and the server-accepted relay topology in the hops test.
Reviews: the local Codex review ended with no findings on round 2. The online reviews on this head (OpenAI, pullfrog) also found nothing. CI passed, and quest check --base origin/main passed.
codex / Codex land fixer: This maintainer pick already used its mechanical fi·x attempt. Run /quest-iterate to diagnose the repeated failure, then pick it again.
quest land removed this pull request from the queue: the batch check failed (exit 101).

Main's #7311 made moq_consume_audio take a moq_delay pointer; the merged
test still passed a bare microsecond count and failed to compile.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The batch failed because the new audio-enabled Rust test supplied integer zero to moq_publish_media_frame, whose current API takes moq_timestamp. The fix uses the existing micros(0) helper. After merging base, external C validation also found the timestamp fixture calling moq_origin_request without its optional epoch arguments; adding NULL, 0 preserves its unpinned request. Both changes only adapt test call sites. All 166 Rust tests and all three external C fixtures passed.

Problem
C request preparation, origin requests, and follows reported a malformed epoch differently from publication announcements, C consumers could not query audio rendition enablement, and received route hops had no C API test coverage.
Approach
MOQ_ERROR_INVALID_CONFIG:moq_publication_announce,moq_broadcast_request_prepare(preserving the pending request and output handle on refusal),moq_origin_request, andmoq_origin_follow(NULL or empty still means unpinned).moq.hand linkedlibmoq.abefore exercising its decode consumers.quest/m1/c/api-gaps.mdto what remains (caller timestamps for JSON windows and disabling pre-encoded simulcast rungs, added to the quest after this PR opened), and updates its link inquest/m1/c/README.mdand the reference inquest/m1/api-audit/route/handle.md.Impact
moq_broadcast_request_prepare,moq_origin_request, ormoq_origin_followreturnsMOQ_ERROR_INVALID_CONFIG(-40), replacingMOQ_ERROR_INVALID_CODE(-15), matchingmoq_publication_announce. Migrate callers that match the malformed-epoch error toMOQ_ERROR_INVALID_CONFIG; signatures are unchanged.int32_t moq_consume_audio_enabled(uint32_t catalog, uint32_t index, bool *dst)reads enablement from that catalog snapshot, likemoq_consume_video_enabled. Missing optional enablement reads as true. On failure, the destination is unchanged. Rebuild with the matching generated header and library to use it.doc/lib/c/index.md, and feat(net)!: routes carry an instance and a per-instance epoch #7489 will need to carry the new malformed-epoch code (MOQ_ERROR_INVALID_CONFIG) into whatever epoch-taking C functions it keeps.rs/moq-cfile, so these epoch APIs still apply.Alternatives
Retaining the error-code inconsistency or exposing enablement only for video conflicts with the maintainer's settled decisions (one PR,
MOQ_ERROR_INVALID_CONFIG, add the audio query, test relay hops). A dedicated epoch error would add an unnecessary code at this cut.Choices made without asking
moq_origin_requestandmoq_origin_follow(review finding), since the quest's goal is one malformed-epoch code everywhere.Validation
cargo test -p moq-c: 164 passed (the hops test failed with the original client-ingest topology; passes 5/5 after the fix).just rs c-tests: C fixtures and doc samples compile against the generatedmoq.h, linklibmoq.a, and pass.nix develop --command just ci origin/main(CI_STRICT): passes on the final head.quest check --base origin/mainpasses.cargo test -p moq-c165 passed,just rs c-testspassed,nix develop --command just ci origin/mainpassed,quest check --base origin/mainpassed.Review
mechanical fix by codex / Codex:
Merged base and mechanically adapted C-package fixtures to the timestamp and optional-epoch APIs; passed cargo fmt --all --check, cargo nextest run --locked -p moq-c --tests (166 passed), and LOCAL_SUPERVISED=1 bash sh/rs/c-tests.sh (all three C fixtures passed), with LIBCLANG_PATH set to the installed library.(head 8b72ab3)Re-land iterate (2026-11-01), head 196bbc5: local review skipped under the simple-review rule. Since the reviewed head d641d6b, the changes are base merges plus two edits that touch only docs and tests:
doc/lib/c/index.mdconflict resolution keeps main's new demand and rendition text and themoq_consume_audio_enabledmention;moq_consume_audiotake aconst moq_delay *, and this PR's audio disabled test still passed a bare10_000_000, somoq-c's test build failed (error[E0308]atrs/moq-c/src/test.rs:1018). The test now passes&TEN_SECONDS, the same 10 s budget.Earlier rounds:
Merged base; re·solved quest deletion conflict by retaining newly added pending tasks and their index link.(head e2d22bb)Merged base cleanly and replaced the dangling completed-quest link with plain text, preserving its requirement.(head de59b27)quest review --deep, public API change).moq_origin_request/moq_origin_followstill mapped a malformed epoch toMOQ_ERROR_INVALID_CODE.Follow-ups
