Problem

A session mints an instance for a route whose wire (moq-lite 06 or older, moq-transport) carries none, and marked it with an in-band ~ prefix on the text. Any caller could spoof a minted instance by naming one ~..., and a real name starting with ~ was ambiguous.

Approach

• Rust: moq_net::Instance is { text, minted }. FromStr, TryFrom<String>, and random() build only named instances; only a session mints one (pub(crate)). Equality, ordering, and hashing include the flag, so a named instance never equals a minted one with the same text. Display/as_str() is the bare text.
• Wire (lite-07 only, moq-lite-07-wip): a Minted (8) byte follows every Instance: ANNOUNCE_START, ANNOUNCE_RESTART, TRACK, TRACKS, SUBSCRIBE, FETCH, DATAGRAMS. 0/1, else PROTOCOL_VIOLATION; an empty pin flagged minted is a PROTOCOL_VIOLATION. The draft drops the ~ convention.
• FFI: MoqInstance is an opaque uniffi object exporting Debug, Display, Eq, and Hash, with a named-only parse, text(), and is_minted(). A record would let any caller build a minted one. It replaces the text in MoqRouteOptions.instance, MoqRouteInfo.instance, MoqRoute::instance_id, MoqClaim::instance_id, and the request/follow pins, so an announced minted instance passed back pins that stream.
• Generated C (c/moq): the C backend of our generator fork refused exported traits on objects. kixelated/uniffi-bindgen-cpp#7 renders them as moq_instance_eq/_ne/_hash/_to_string/_to_debug_string, tagged v0.11.0-kixelated.8+v0.32.2; the flake, the CI action, rs/moq-ffi/build.sh, and cpp/moq/README.md pin it.
• Hand-written C (rs/moq-c): instances are u32 handles: moq_instance_parse (named only), _text, _minted, _equal, _free. Route options and the pins take a handle (0 for none); moq_route_instance/moq_claim_instance return a caller-owned one; an announcement's route.instance lives with the announcement.
• Wrappers: Go, Python, Kotlin, Swift, Dart, C++, and OBS expose an Instance alias of the generated object, compared by value: Go Eq, Python ==/hash, Kotlin equals/hashCode, Swift Equatable/Hashable, Dart ==/hashCode, C++ eq() (== on a shared_ptr compares handles; the README says so).
• JS: named instances stay branded strings, used with === and as map keys in ~34 files. A minted instance is now a Minted object instead of a string with an in-band mark. Its constructor is private and also checks a module-private token, so a caller who reaches the class through a prototype still cannot build one. Minted instances are interned by text with a WeakRef table, so === and map keys still compare by value, and Instance.isMinted is a #private brand check. Minting lives in js/net/src/mint.ts, which the package does not export. The branded-string mark this replaces could be forged by any plain-JS caller passing "\uDC00...". That lost the flag's point, and it was an in-band sentinel again.
• Readers: signing and catalog checks keep reading is_minted(). moq_crypto::e2ee::Epoch::of and JS of skip a minted instance explicitly. JS signing scopes, the routing spread hash, and the fetch-coalescing key read Instance.text(). So the hash agrees with Rust's instance_key, and two minted fetches no longer share a key (JSON prints an object as {}). @moq/hang's InstanceSchema refuses ill-formed text, which UTF-8 cannot carry.
• Tests:
  • Unit tests on both sides pin the flag byte, round-trip both kinds, and refuse a bad flag.
  • An integration test forwards a minted instance lite-06 → lite-07 and checks it stays minted and equal.
  • job_reannounced names its instance ~job, to prove a tilde name stays named.
  • Every binding (moq-ffi, moq-c, generated C, C++, Go, Python, Kotlin, Swift, Dart) has a lite-06 session test. It pins request and follow with the announced minted instance, and checks that its parsed text is a different, named instance that does not resolve.
  • JS tests check that a minted instance cannot be built through its class.

Impact

• Breaking (moq-net): "~x".parse::<Instance>() is now a named instance; is_minted() is true only for one a session minted. Migrate: nothing to change unless code built a minted instance from text, which is no longer possible outside a session; tests use moq_net::fuzz::minted_instance() (feature fuzz).
• moq-net: Instance equality includes the minted flag; Debug prints "minted" for one.
• Breaking (moq-ffi): instances are MoqInstance objects, not strings: MoqRouteOptions.instance: Option<MoqInstance>, MoqRouteInfo.instance: MoqInstance, MoqRoute::instance_id() -> Option<MoqInstance> (none for a cancelled hidden route that never read or announced one), MoqClaim::instance_id() -> MoqInstance, and follow/request(path, Option<MoqInstance>). Migrate: MoqInstance::parse(text) where you named one, .text() where you printed or stored it, and pass a reported instance back as is to pin it.
• Breaking (wrappers): the same change as each language's Instance type. Go: RouteOptions is now a wrapper struct taking *Instance (field names unchanged), ParseInstance(text), compare with Eq. Python: moq.Instance.parse(text), Route.instance is Instance | None. Kotlin/Swift/Dart: Instance.parse(...); Swift Route.instance is optional. C++: pass nullptr, not std::nullopt, for no instance; compare with eq().
• Breaking (moq-c): moq_route_options.instance is a uint32_t handle (0 for a fresh one) replacing instance/instance_len; moq_route_info.instance is a handle the announcement owns; moq_route_instance(route) and moq_claim_instance(claim) return a handle to free with moq_instance_free instead of writing a string; moq_origin_request/moq_origin_follow take a uint32_t instance (0 unpinned) instead of instance, instance_len. New: moq_instance_parse, _text, _minted, _equal, _free.
• Breaking (c/moq): moq_route_instance_id and moq_claim_instance_id return a moq_instance * (free with moq_instance_free); pins and route options take one; new moq_instance_parse, _text, _is_minted, _eq, _ne, _hash, _to_string.
• Breaking (@moq/net): Instance.Valid is Instance.Named | Instance.Minted: a minted instance is an object, not its text. Read the text with Instance.text(), not as a string. Instance.parse refuses ill-formed text (a lone surrogate). Instance.minted() (was @internal) is gone from the entrypoint.
• @moq/hang: InstanceSchema refuses ill-formed instance text.
• moq-crypto / @moq/crypto: e2ee Epoch::of / of return none for a minted instance.
• Wire: lite-07 (moq-lite-07-wip, unpublished) adds Minted (8) after each Instance. lite-06 and moq-transport bytes are unchanged. Two relays both on moq-lite-07-wip must run builds from the same side of this change; moq.pro's mixed relays negotiate lite-06, which is unaffected.
• Build: uniffi-bindgen-cpp moves to v0.11.0-kixelated.8+v0.32.2; reinstall it outside Nix.
• Docs/drafts: drafts/draft-lcurley-moq-lite.md (fields, minting paragraph, changelog), drafts/draft-lcurley-moq-hang.md, doc/concept/identity.md, doc/concept/moq-lite.md, doc/lib/c, doc/lib/cpp, and the moq-c, C++, and Python READMEs. Per the root rule only the release cut edits MIGRATE.md; rs/moq-net/MIGRATE.md's ~ line and c/moq/MIGRATE.md's instance lines are for the cut to replace with this Impact note.

Alternatives

• JS: keep every instance a branded string and refuse a marked one at public entry points. A forged mark is byte-identical to a real one, so there is nothing to refuse, and it keeps the in-band sentinel.
• JS: make every instance an object. Named instances are user and catalog text compared all over the codebase; only minted ones need to be unforgeable, so wrapping both buys churn and no safety.
• FFI: a record with a minted field. Any caller could build one, which lets a binding mint.
• FFI: drop the exported traits so the old generator accepts the object. Every language would then compare instances by handle, so a pin, a map key, or a cached instance would silently mismatch.
• A varint "instance kind" (none/named/minted) replacing the empty-means-none pin: a bigger wire change for no behavioral gain over a flag byte.

Choices made without asking

• Fixed the generator fork and cut its tag (v0.11.0-kixelated.8+v0.32.2, on the head of kixelated/uniffi-bindgen-cpp#7) rather than shaping moq-ffi around the C backend's gap; merging that PR into the fork's kixelated/uniffi-0.32 is left to the maintainer, and the tag pins the commit either way.
• moq-c instances are slab handles like its other objects, and an announcement owns its own.
• moq-mux dev-depends on moq-net's hidden fuzz feature for one test hook, rather than standing up a lite-06 session harness in moq-mux.
• No shared corpus fixture for the flag: js/net's lite-07 ANNOUNCE_START still predates the route layer (tracked by routes/js.md), so each side pins the bytes in its own unit tests.
• Binding edits touch only instance types and the request/follow consumers. Kotlin's new test sits in SmokeTest.kt next to the lifecycle calls #8363 changes, and OBS moq-output.cpp changes one line, so whichever lands second may need a small rebase. Nothing here depends on connection-state phases.

Follow-ups

• When routes/js.md lands, add a lite-07 ANNOUNCE_START corpus case with the minted flag (recommend: fold into that quest).
• Swift: just swift check skips its build and tests without a Swift toolchain on Linux; the new Swift test was compiled and run by hand with Swift 6.3.3.

Checks

On 433d23654bfdc4bb34e22bb261cb8e664e4722e7: just fix and just check passed. check c and check cpp passed in the dev shell, after clearing a local CMake cache that still pinned the old generator (kixelated.7). just test interop --all passed. A first run under a host load average near 56 failed three lite-06 JS-native/C media lanes on frame timing (skipping slow groups). No code changed between that run and the clean rerun.

Iteration on CodeRabbit's review: fixed the identity guide wording (a broadcast generates its instance, and pinning a minted instance means passing back the reported one), freed the moq-c tests' instance handles, and corrected the stale announce golden comments. Added Route ID / Node ID encoding and golden realignment to routes/js.md. Declined, with replies on each thread: the JS lite-07 Route ID / Node ID findings (they predate this PR, from moq-dev/moq#8293, and routes/js.md tracks them), refusing minted instances in signing producers, raising the Kotlin moq-ffi floor (the release cut owns it), and matching the error kind in the Swift test (repo rule: never match on errors).

Reviewed changes

• Rust moq-net — Instance is { text, minted }: only a session mints (pub(crate) minted / decoded), FromStr/TryFrom<String>/random name only, and eq/order/hash include the flag while Display/as_str stay text. Reader sites (moq-mux::source, moq-gst, moq-crypto sign and e2ee epoch, route meta carried) now test the flag instead of the ~ prefix.
• Wire, lite-07 only — a Minted (8) byte follows every Instance (ANNOUNCE_START/RESTART, TRACK, TRACKS, SUBSCRIBE, FETCH, DATAGRAMS). Both languages funnel through lite::instance / lite/instance.ts, so the order matches the draft and lite-06 bytes are untouched; empty-and-minted is refused. Draft, lite changelog, golden hex, and an integration test (lite-06 → lite-07 forwarding keeps the flag) all move together.
• JS @moq/net — named instances stay branded strings; a minted one is an unforgeable Minted object from the unexported src/mint.ts, interned by text so ===, map keys, and Signal identity keep working. Instance.text() is new, isMinted is a brand-check type guard, and every text consumer (pin, fetch key, spread hash, signing scope, interop probe) reads the text.
• FFI / C / wrappers — new opaque MoqInstance (parse/text/is_minted, exported Debug/Display/Eq/Hash) replaces the string across route options, route info, claim/route instances, and request/follow pins; rs/moq-c uses u32 slab handles with an announcement owning its own; Go/Python/Kotlin/Swift/Dart/C++ expose a value-equal alias. Each gets a lite-06 session test proving the announced minted instance pins while its parsed text does not.

Checked and holding: every lite-07 pin/route site routes through the shared helpers in both languages (including ANNOUNCE_RESTART); relay forwarding preserves the flag; moq-c keeps parse_*_route_options outside State::lock() so lookup_instance cannot self-deadlock; the C++ OBS instance_id()->text() cannot see a null optional because that route was just created visible; Go's **ffi.MoqInstance matches the existing optional-object idiom; and js/watch's rootDir: ".." follows the js/crypto/js/json precedent for cross-package test imports.

ℹ️ Two announce fixtures stopped describing the same stream (pre-existing)

Worth knowing, not introduced by this PR and nothing to change here: the "pinned from each other" announce constants no longer encode the same stream, so neither side proves the other's codec for the new flag byte.

Technical details

# Announce fixture pins have diverged

## Affected sites

- `rs/moq-net/src/lite/compress.rs:416` — `GOLDEN`, asserted against
  `encode_announces(&golden(), true)` where `golden()` builds five announcements with empty hop
  chains (`Announced::Start(.., vec![])` etc.).
- `js/net/src/lite/announce.test.ts:347` — `GOLDEN`, whose comment says it is "Pinned from the Rust
  encoder (`lite::compress::tests::golden_stream_is_pinned`)", but the bytes carry hops
  `0x1111`, `0x2222`, `0x3333`, `0x4444`, `0x5555` and `GOLDEN_RESOLVED` expects them.
- `rs/moq-net/src/lite/compress.rs:442` — `JS_LITERAL` also has no hops, while the JS literal
  stream at `js/net/src/lite/announce.test.ts:355` does.

## What this means

Both hex blobs were bumped for the `Minted` byte in this PR, so each side still passes
`decode`/`encode` against its own constant. What is lost is the cross-language check: the same
`compress.rs` comment says "js/net decodes the same hex, so a codec change on either side breaks
both", which has not been true since lite-07 replaced hop chains with a route id. A future
divergence on one side would break only that side's constant.

## Note

The PR body already records that there is no shared corpus fixture for the flag yet (deferred to
`routes/js.md`), so this is consistent with the current state, not a regression from it.

Automated review by review (OpenAI)

Reviewed head: 1ccdfb1

No actionable defects found in the Rust/JS provenance representation, lite-07 flag codecs and their callers, signing/catalog checks, or opaque-instance ownership and pinning through the bindings. The explicit flag addresses the ambiguous text marker without changing lite-06 encoding.

Verification limits: GitHub-only static review; I did not run builds, tests, binding generation, or runtime interoperability checks. The exact-head Check workflow was still in progress. Confirm its result before landing; this comment is not an approval.

Walkthrough

Instances now store minted status separately from their text. Lite-07 messages encode and preserve that status, and APIs across several language bindings use instance objects for route values and request or follow selectors. The C API uses numeric instance handles. Tests cover minted instances announced over Lite-06, their use for pinning, and their distinction from parsed named instances with the same text.

Merge Risk: Moderate · up to 433d2

Lite-07 messages now carry a Minted byte, but the JavaScript Lite-07 implementation still lacks the route-layer fields that Rust sends, so JavaScript peers may reject routed announcements or misread unpinned requests. Interop for that path is skipped until the JS route-layer port lands. Align the JavaScript fixtures, and confirm the Kotlin dependency floor before release, before merging.

Inline comments:
Review comments at @doc/concept/identity.md:
- Around line 95-97: Update the identity guide’s terminology around
`Instance::is_minted` and `Instance.isMinted`: describe broadcasts or fresh
local routes as generating instances, and reserve “minted” for instances created
by a session. Preserve the distinction that a named instance can be valid even
when it is not minted.
- Around line 95-98: Update the identity guidance to tell readers to retain the
original minted Instance and reuse it when pinning later requests; do not parse
its text to recreate the instance, since parsing does not preserve the minted
flag represented by Instance::is_minted and Instance.isMinted.

Review comments at @js/crypto/src/sign/scope.ts:
- Line 19: Update both signing producer creation paths to reject session-minted
instances before signing, while continuing to allow named instances; ensure the
`Instance.text(instance)`-based scope cannot be used to accept a replay across
minted and named instances.

Review comments at @js/net/src/lite/announce.test.ts:
- Around line 346-347: Align the Lite-07 codec behavior between JavaScript and
Rust, then update the GOLDEN fixture and its counterpart so both test suites pin
the same stream. Verify the shared fixture represents the same encoded data in
both implementations.

Review comments at @js/net/src/lite/instance.ts:
- Around line 15-17: Update the Lite-07 FETCH encoding in the instance
serialization flow to write the Node ID between the pin and track name, using
zero when no node is selected. Locate the request construction around the
`instance` check and preserve the existing pin and track-name encoding order.
- Line 40: Update the announcement encoding and decoding near encode(w,
instance) to handle the Route ID before the instance, so Route ID 0 is not
interpreted as the instance length. Remove the hop block for lite-07 while
preserving the remaining layout and existing validation.

Review comments at @rs/moq-c/src/test.rs:
- Around line 64-68: In the test setup using parse_instance, retain ownership of
each allocated instance handle for named route options and pinned requests, then
call moq_instance_free after the corresponding API call has borrowed it. Ensure
every test-owned handle is freed during cleanup without freeing handles before
the API call.

Review comments at @rs/moq-ffi/src/instance.rs:
- Around line 13-15: Update the Kotlin wrapper’s published moq-ffi minimum
version to the first release that includes the MoqInstance API, so its
dependency range no longer permits 0.4.12 or earlier bindings; verify the
release boundary before changing the version constraint.

Review comments at @swift/Tests/MoqTests/SmokeTests.swift:
- Around line 272-275: The named-instance rejection test in the
`consumer.request` flow can pass on any error. Assert that the caught error
specifically indicates rejection of the named instance, using the established
error type or assertion pattern, so failures before instance routing do not
satisfy the test.

Reviewed changes

This run covers the delta since the prior pullfrog review (1ccdfb1..433d236). It is review-response work rather than behavior change.

• Clarified the identity guide so a broadcast generates its instance and only a session mints one, and documented that pinning a minted instance means passing back the reported one (its text parses to a different, named instance that never resolves to that route).
• Removed the false "a codec change on either side breaks both" claim from the Rust and JS announce golden comments, and recorded the Rust/JS route-layer realignment in quest/m2/cluster-routing/routes/js.md.
• Freed the instance handles the moq-c tests parse, after the call that borrows them (create_route, resolve_pinned, and the pin/follow test).

- Line 25: Update the “A new stream takes a new instance” statement to clarify
that a random instance is generated by default only when the publisher does not
supply one through RouteOptions::with_instance.

Review comments at @quest/m2/cluster-routing/routes/js.md:
- Line 21: Update the lite-07 routing plan so TRACK, TRACKS, SUBSCRIBE, FETCH,
and DATAGRAMS always encode a Node ID, including unpinned requests; use 0 when
the publisher selects the node. Keep the Node ID in the Rust-compatible field
order so subsequent request fields remain aligned.

Require Node ID on unpinned requests too.

The plan limits this requirement to requests that pin an instance. Rust also encodes Node ID when the instance is absent. Omitting it would misalign the remaining fields in an unpinned request. Require it for TRACK, TRACKS, SUBSCRIBE, FETCH, and DATAGRAMS, with 0 when the publisher selects the node. (raw.githubusercontent.com)

Agreed: Rust encodes the Node ID on every lite-07 request, pinned or not. The quest now says TRACK, TRACKS, SUBSCRIBE, FETCH, and DATAGRAMS always carry it, 0 when the publisher selects the node.

@kixelated Thanks for the update. I could not verify it: the checkout at 433d2365 still says Node ID is required only for requests that pin an instance. Please retry after the updated revision is available.
