feat(recv): parse the envelope type, enc mediatype and report-to-admin group IQs by jlucaso1 · Pull Request #1308 · oxidezap/whatsapp-rust

jlucaso1 · 2026-08-14T19:23:31Z

Summary

Four attributes the official client reads or writes on the receive path had no counterpart here, and three of them were fields this crate already declared and never assigned, so a consumer got String::new() with no way to tell a failed parse from an absent attribute. <message type> now reaches MessageInfo::type as a typed wire enum, with <meta polltype> scoped to poll envelopes the way the official parser scopes it. envelope_is_coherent states the rule the official client uses to decide whether a decrypt-fail="hide" stanza may be nacked, and only answers: nothing in this crate consults it. A retry receipt for a stanza that asked for hidden failures now reports the HID_FAILED_DECRYPT bit in <meta mode>. <enc mediatype> fills MessageInfo::media_type and <enc state> / <enc session_type> reach Event::DecryptedPayload per node, both read in the loop the receive path already runs over every <enc>. Finally the w:g2 report-to-admin pair lands as two IQ specs with their own response types.

Protocol evidence

IR read at oxidezap/whatspec@main, generated/manifest.json stamping waVersion 2.3000.1044659339, which is exactly what wacore::version::WA_WEB_VERSION carries. No drift, nothing to flag there. docs/captured-js/ is not in the tree and was not available, so every claim below is from the IR.

Envelope type and <meta> (items 1 and 4a) -- jq -c '.incoming[] | select(.shape.parserName=="incomingMsgParser") | .shape.fields[] | select(.name=="type" or .name=="enc" or .name=="meta")' incoming/index.json. Confirmed: type is attrEnum, required, over STANZA_MSG_TYPES (WAWebHandleMsgCommon) with the seven values text, media, medianotify, pay, poll, reaction, event. <enc> is mapChildrenWithTag with repeats: true and carries type (attrEnumValues over CiphertextType), mediatype, count, decrypt-fail, state, session_type. <meta> carries polltype as attrEnumOrNullIfUnknown over POLL_TYPES (creation, quiz_creation, vote, result_snapshot, edit), plus thread_msg_id and thread_msg_sender_jid among others.

Media type inventory -- jq -c '.enums[] | select(.name=="EncMediaType") | [.variants[].value]' enums/index.json returns the 30 values, all of which are mapped here.

Retry receipt <meta mode> (item 3) -- jq -c '.stanzas[] | select(.moduleName=="WAWebSendRetryReceiptJob")' stanza/index.json confirms the three children <retry v count id t error?>, <registration> and <meta mode="<int>">, with mode an integer. ReceiptModeBitPosition in enums/index.json is {"valueKind":"int","variants":[{ORPHAN,0},{NO_CHECKMARK_UX,1},{HID_FAILED_DECRYPT,2}]} -- bit positions, so HID_FAILED_DECRYPT is 1 << 2 == 4. Two props gate it: receipt_mode_bitmask_enabled (30084) and web_send_hid_failed_decrypt_in_receipts_enabled (31113), both bool, both default: false / altDefault: true, both already vendored.

Report-to-admin (item 4b) -- jq on iq/index.json for makeReportMessagesRequest and makeGetReportedMessagesRequest. Both are w:g2, one set with <reports><report message_id/></reports> and one get with an empty <reports/>. The get response carries addressing_mode (lid/pn) on the <iq> via groupAddressingModeMixin with sameNode: true, repeated <report message_id>, each with repeated <reporter jid timestamp> and an optional identity mixin whose union arms are {phone_number, username}, {phone_number} or {username}.

Where the IR differs from the task text. The prompt said to validate the to target. Both stanzas report "target": "s.whatsapp.net", but so does every w:g2 stanza in the IR, including makeSetSubjectRequest and makeAddParticipantsRequestAddParticipant, which this repo has always addressed to the group JID. So the field is the namespace's base target, the group mixin overrides it, and both requests are addressed to the group JID here. The set error arms are 400 bad-request, 403 forbidden, 404 item-not-found, 423 locked, 429 rate-overlimit as stated; the get arms differ from the prompt: 401 not-authorized in place of 403 forbidden, otherwise the same list.

The coherence rule (item 2) is not in the IR -- it is control flow, which the IR does not model, and docs/captured-js/ was unavailable. What I could validate is the vocabulary it uses: STANZA_MSG_TYPES and POLL_TYPES are exactly as quoted, and pay and event are genuinely the two members of STANZA_MSG_TYPES that appear in neither leg. The rule is implemented as the prompt transcribed it, and the doc comment on envelope_is_coherent says plainly that it answers a question and drives nothing.

Also unverifiable, and implemented on the stated reading: when HID_FAILED_DECRYPT is set. The IR gives the bit and the node, not the branch. The bit is set from the stanza's decrypt-fail="hide", which is the observable signal the bit's own name refers to and the only thing this client can see; the alternative reading ("retry with no placeholder created") has no counterpart here, since a placeholder is dispatched regardless of hide mode. ORPHAN is left unset: nothing in this tree models an orphan addon. The concept does exist upstream -- there is a web_send_orphan_in_receipts_enabled prop -- but inventing a second bit from a prop name would be a guess.

On generating these enums instead of hand-writing them. Worth checking and it does not work today. whatspec-codegen has no enum reader at all: tools/whatspec-codegen/src/ir.rs declares no enum type and the six emitters are proto, version, appstate, tokens, abprops and mex. Beyond the missing emitter, the IR would only cover part of this: EncMediaType and ReceiptModeBitPosition are first-class entries in enums/index.json, but STANZA_MSG_TYPES and POLL_TYPES are not -- they exist only inline as enumRef objects inside incomingMsgParser's shape, so an emitter reading the enum registry would generate one of the three enums here and leave the other two hand-written. Two of the three would also need shaping the registry cannot express: PollType is deliberately closed (attrEnumOrNullIfUnknown) while StanzaMessageType and EncMediaType need a #[wire_fallback] arm, and ReceiptModeBitPosition stores positions, so the 1 << 2 shift stays in hand-written code either way. Adding an emitter that also mines inline enumRefs is a real improvement and a separate change: it means a new IR document reader, a new committed artifact and a committed_artifacts.rs entry, which this batch put out of scope.

Changes

StanzaMessageType, PollType, EncMediaType in wacore/src/types/message.rs, all WireEnum. The first two mirror STANZA_MSG_TYPES and POLL_TYPES, the third mirrors the IR's EncMediaType.
parse_message_info reads <message type>. Absent stays None, unrecognized becomes Unknown(raw) -- the official parser rejects the stanza in both cases, and rejecting here would drop a message this client delivers today for an attribute nothing downstream needs.
<meta polltype> is read only on a poll envelope, matching how the official parser scopes it; an unrecognized value is None, per attrEnumOrNullIfUnknown.
<meta thread_msg_id> / <meta thread_msg_sender_jid> now fill the two MsgMetaInfo fields that declared them.
envelope_is_coherent is a pure function over (type, polltype, decrypt-fail mode). Nothing calls it in this crate.
RECEIPT_MODE_HID_FAILED_DECRYPT and build_receipt_meta_node in wacore/src/protocol/retry.rs; send_retry_receipt appends <meta> only when the bitmask is non-zero, and only while both gating props are on.
Both receipt props added to iq::props::WATCHED. AbPropsCache::apply_props keeps only codes in its interest set, so reading a prop that is not listed there discards the server's value and falls through to the registry default forever.
RetryRequestOptions::with_decrypt_fail_mode carries the mode from handle_decrypt_failure to the receipt. Additive; the default is Show, so an existing caller sends no <meta>.
<enc mediatype> aggregates into MessageInfo::media_type in the same pass that enumerates the stanza's <enc> nodes; <enc state> and <enc session_type> ride EncPayload to Event::DecryptedPayload.
ReportGroupMessagesIq / GetReportedGroupMessagesIq with ReportedGroupMessages, ReportedGroupMessage and GroupMessageReporter, wrapped as Groups::report_messages_to_admins and Groups::get_reported_messages, re-exported through features/groups.rs -> features/mod.rs -> lib.rs.

Breaking, with migration:

MessageInfo::type is Option<StanzaMessageType>, was String. info.r#type == "text" becomes info.r#type == Some(StanzaMessageType::Text); to keep string comparisons, info.r#type.as_ref().map(StanzaMessageType::as_str) == Some("text"). Code that treated "" as "no type" now matches None.
MessageInfo::media_type is Option<EncMediaType>, was String. Same shape of migration, with EncMediaType::as_str.
MsgMetaInfo::deprecated_lid_session is removed. It was never assigned and appears nowhere in the IR's <meta>, so no reader can have depended on a value.
handle_decrypted_plaintext and EncPayload gained fields/arguments; both are crate-internal.

One outgoing-wire consequence worth naming. build_nack_node already echoed MessageInfo::type as the nack's type attribute and, because the field was never assigned, the branch was dead and every nack went out without it. Filling the field makes that attribute appear, which is what the official client sends. No nack decision changed -- same stanzas, same reasons, same counts -- only the attribute is no longer missing. The pre-existing nack_omits_type_when_empty test became nack_omits_type_when_absent and asserts on None instead of String::new(); that is the only existing test whose contract moved.

Decisions

String vs typed enum. Typed, with a #[wire_fallback] arm holding the raw bytes. This is free: Option<StanzaMessageType> and Option<EncMediaType> are both 24 bytes, the same as the String they replace, because the fallback's String supplies the niche for both the enum discriminant and the Option. size_of::<MessageInfo>() is unchanged (numbers below). Closing the sets outright was rejected for the two that come off the wire uninterpreted -- the server can add a value tomorrow and losing its text would be worse than an extra variant. PollType is closed, because the IR says the attribute is enum-or-null: dropping an unknown value is the faithful behaviour, not a shortcut.

Reuse of StanzaType. Not reused. wacore/src/send.rs's StanzaType is a Copy send-time override with a closed set and no unknown arm, and a receive type needs both medianotify and a fallback that owns a String. Bolting those on makes the send type non-Copy and lets a caller ask to send Unknown("..."), which is a worse trade than two types. They are different directions of the same attribute and the duplication is two lists of literals; the receive type is the complete one and the send type is a deliberate subset of what this client can construct.

Where mediatype lives. Aggregated onto MessageInfo, first <enc> that declares one wins, in the enumeration order the crate already documents (direct children, then this device's under <participants><to>). That is a wider source than WA Web's parser, which maps only the direct children; the two agree on every stanza seen so far, since the attribute describes the message and every device copy repeats it, and the field doc names the difference. The aggregation runs in the same single pass that fills the enc-node vector, before parse_message_info, so the field lands while the struct is still owned: a custom enc handler or a per-node failure event that clones the Arc later cannot observe a half-finished MessageInfo. Documented on the field itself, including that a divergent later value is dropped, and covered by a fan-out test with three <enc> nodes where the first declares nothing and the next two disagree. Aggregating is right for this attribute specifically: it describes the message, and a fan-out is the same message repeated per device. Per-<enc> data that genuinely varies by node -- state, session_type -- went to DecryptedPayload instead, which is already per-node.

session_type and state. Both carried, neither interpreted. Reading them in the same loop is one attribute lookup each on a node already in hand, and both are raw strings on DecryptedPayload with doc comments saying this build does not model the values.

The abprop gate. Gated, on two props, both required. receipt_mode_bitmask_enabled (30084) introduces the <meta mode> node at all; web_send_hid_failed_decrypt_in_receipts_enabled (31113) is a separate experiment covering this one bit, so an account enrolled in the first and not the second must not send it. Both are default: false / altDefault: true. With a cold props cache is_enabled falls back to the registry default, so the first retries after connect go out in exactly the shape this client has always sent -- no new attribute reaches a server that never turned the flags on, and the worst case is that a few early receipts omit a diagnostic bit. Sending it unconditionally would have inverted that risk for no gain, since nothing in this client's own behaviour depends on the bit. There is a test for each of the four states: both props on, no hidden failure, bitmask prop only, and both off.

Public surface. The type changes break consumers and the migration lines are above. Pre-1.0, and the alternative was keeping two fields whose only possible value was the empty string.

Dead fields

Everything found that was declared and never assigned:

MessageInfo::type -- fixed, now parsed.
MessageInfo::media_type -- fixed, now aggregated from <enc mediatype>.
MsgMetaInfo::thread_message_id, MsgMetaInfo::thread_message_sender_jid -- fixed, both are in the IR's <meta> as thread_msg_id and thread_msg_sender_jid.
MsgMetaInfo::deprecated_lid_session -- removed. Never assigned, and grep -r deprecated_lid_session over the whole IR returns nothing, so there is no wire attribute it could ever have been parsed from.

Cost

size_of, measured with a mirror of the previous field set in the same build (repr(Rust) layout depends only on the field types):

	before	after
`MessageInfo`	952	952
`MsgMetaInfo`	264	264

Option<StanzaMessageType> = 24 (was String, 24). Option<EncMediaType> = 24 (was String, 24). PollType = 1, absorbed into existing padding, which is also why removing Option<bool> and adding Option<PollType> leaves MsgMetaInfo unchanged.

Allocations, counted with a counting global allocator around parse_message_info on a <message type="media"> with one <enc mediatype="image">:

known type: 1 allocation for the whole parse -- the message id, which was already the only one. Reading type costs zero: every known value is a unit variant.
unknown type: 2 -- the id plus the preserved raw string, paid only by a value this build does not model.

<enc state> and <enc session_type> allocate only when the attribute is present, which it is not on ordinary traffic. The receipt's <meta mode> allocates nothing either: NodeValue's integer conversion writes through itoa into a CompactString, which inlines a value this short.

Bench: wacore/benches/message_utils_benchmark.rs::bench_parse_message_info exists and covers exactly this function. Medians, one run each, same container:

shape	before	after
dm_pn	370.1 ns	378.6 ns
group_lid	394.5 ns	403.0 ns
self_sent	307.2 ns	325.9 ns
status_broadcast	356.0 ns	367.7 ns

Consistently 2-6% higher. Calling that noise would be wrong: four shapes all moved the same way, and a per-sample spread is not the same as a biased median. It is a small real cost, not a free change. The added work is one attribute read plus a match for the type, and two more attribute reads inside the <meta> block that only runs when <meta> exists. CodSpeed, which measures instructions rather than wall clock on a shared runner, is the better instrument here and did not flag it.

Reported, not fixed

The nack divergence is real. spawn_nack fires from handle_plaintext_failure, from the msmsg paths in src/message/msg_secret.rs and from two arms in src/message/receive.rs, none of which consult the envelope type. Under the official rule an incoherent combination cannot be nacked, so at minimum this client nacks two shapes it would not: a pay or event envelope that fails to decode (outside both legs), and a text or media envelope carrying decrypt-fail="hide" (the hide leg admits only reaction and poll+vote). handle_plaintext_failure already receives the DecryptFailMode it would need and ignores it. Not changed here -- this batch observes, and a nack is a control-flow decision.

Second, smaller: the HID_FAILED_DECRYPT trigger is implemented on the reading argued above and could not be confirmed against the bundle, since docs/captured-js/ is not in the tree. If someone with the bundle finds the bit keys off placeholder creation rather than off decrypt-fail, the change is one condition in send_retry_receipt.

Validation

cargo fmt --all
cargo test -p wacore --lib            # 1453 passed
cargo test -p whatsapp-rust --lib     # 1704 passed
cargo test --doc -p wacore            # 1 passed, 11 ignored
cargo clippy -p wacore -p whatsapp-rust --all-targets -- -D warnings
cargo bench -p wacore --bench message_utils_benchmark -- parse_message_info

cargo nextest is not installed in this environment, so the suites ran through cargo test. cargo clippy --workspace cannot complete here -- alsa-sys fails its build script for want of a system package -- so it is scoped to the two crates this touches. Full matrix left to CI. e2e not run.

…n group IQs Four attributes the official client reads or writes on the receive path had no counterpart here, and three of them were fields this crate already declared and never assigned, so a consumer got an empty string with no way to tell a missing parse from a missing attribute. - `<message type>` now reaches `MessageInfo::type` as a typed wire enum with the seven values the official parser accepts. That parser rejects the stanza when the attribute is absent or unrecognized; rejecting here would drop a message this client delivers today, so absence is `None` and an unrecognized value keeps its bytes. `<meta polltype>` follows, scoped to poll envelopes the way the official parser scopes it. - `envelope_is_coherent` states the rule the official client uses to decide whether a `decrypt-fail="hide"` stanza may be nacked. It only answers; no control flow in this crate consults it. - A retry receipt for a stanza whose `<enc>` asked for hidden failures now reports the HID_FAILED_DECRYPT bit in `<meta mode>`, built only when the bitmask is non-zero and only while `receipt_mode_bitmask_enabled` is on. - `<enc mediatype>` fills `MessageInfo::media_type`, aggregated to the first node that declares one; `<enc state>` and `<enc session_type>` reach `Event::DecryptedPayload` per node. Both are read in the loop the receive path already runs over every `<enc>`. - The `w:g2` report-to-admin pair (`<reports>` set and get) lands as two IQ specs with their own response types, distinct from the `spam` IQ that reports to WhatsApp rather than to the group's admins. Breaking: `MessageInfo::type` is `Option<StanzaMessageType>` and `MessageInfo::media_type` is `Option<EncMediaType>`; both were `String`. `MsgMetaInfo::deprecated_lid_session` is gone -- never assigned and absent from the protocol's `<meta>`. `size_of::<MessageInfo>()` is unchanged at 952 bytes and a known type costs no allocation.

…ment Two Option<&str> parameters pushed handle_decrypted_plaintext past the argument limit clippy enforces, and they always travel together.

…fore sharing it Two independent props guard the receipt bit: receipt_mode_bitmask_enabled introduces the <meta mode> node, and web_send_hid_failed_decrypt_in_receipts_ enabled is a separate experiment covering this one bit. An account in the first and not the second was being sent a shape the official client leaves off, so both are now required and both are watched. The media type was also being written after the decrypt loop, by which point a custom enc handler or a per-node failure event could already hold a clone of the Arc and observe the field unset. Enumerating the <enc> nodes before the parse lets the value land while MessageInfo is still owned, in the same single pass that fills the node vector.

Dismissed because a newer commit was pushed; Greptile will re-review the current head.

⚠️ Unverified finding
Sandbox verification was unavailable.

Verify deferred annotation propagation.

Confirm that every DeferredPlaintext constructor copies state and session_type from its EncPayload. Confirm that the deferred drain passes both fields into DecryptedPayload. Otherwise normal Signal payload events can lose annotations while the msmsg path preserves them.

As per PR objectives, encrypted-node annotations must flow through deferred plaintext handling and decrypted-payload events.

Two things from the CodeRabbit pass.

Typed tags in GetReportedGroupMessagesIq::parse_response (Major) — not changing this. The rule it quotes is conditional on tagged mode: "In tagged mode it generates a sibling <Name>Tag; parsers must dispatch on <Name>Tag::try_from(node.tag.as_ref()) rather than string literals." That is for a node whose tag selects between alternatives, which is why the two places using it in-tree are CallActionTag and UsyncProtocolResultTag, both over #[wire(tag = "...")] enums with per-variant payloads.

This parser has no alternation. <reports> contains only <report>, which contains only <reporter> — a fixed nesting, walked with required_child and get_children_by_tag, exactly as every other spec in this file does (GetMembershipRequestsIq, GetGroupProfilePicturesIq, and the rest). A tagged WireEnum here would need variants that carry nothing and are never dispatched between, and it would leave this one spec looking unlike its twenty neighbours.

Deferred annotation propagation (flagged unverified) — verified, and it holds. All three DeferredPlaintext constructors carry state and session_type: src/message/receive.rs:875 (main session decrypt), :1000 (identity-retry decrypt) and :1976 (PN→LID migration retry). The drain at :1394 destructures both and passes them into handle_decrypted_plaintext as EncNodeAnnotations, which is the same path that fills DecryptedPayload. The msmsg path in src/message/msg_secret.rs:503 reads them off its own EncPayload, so neither route drops them.

Generated by Claude Code

NodeValue's integer conversion writes through itoa into a CompactString, which inlines a value this short, so to_string() was buying a heap allocation the builder does not need. Also names the one place the media type aggregation reads wider than WA Web's parser.

Dismissed because a newer commit was pushed; Greptile will re-review the current head.
