feat(wacore): bind five more enums to the catalog and retire a dead event - #1310
Conversation
Three findings from auditing what the schema-4 catalog now makes checkable. Six hand-written enums turned out to have a real upstream name in the catalog, found by matching variant sets rather than names: DecryptFailMode, MemberAddMode, MemberShareHistoryMode, DisallowedListAction, GroupParticipantType and CallLinkMedia. They move to WANTED. Nine others match only a synthetic-named entry, which the emitter refuses on purpose, so they stay hand-written for a reason that is now on record. The move needed #[wire_default] in the emitter first. The catalog's variant order is not ours, and the derive takes the first variant as Default when nothing says otherwise, so generating DecryptFailMode from catalog order would have flipped its default from Show to Hide without a compile error. The default is declared per entry and validated against the catalog. Event::PushNameUpdate promised an old-name/new-name comparison and was never dispatched by anything. There is no contact store here to hold a previous name, and a per-connection guess would be worse than nothing: the event would fire inconsistently across reconnects. The payload and the Event variant are gone. MessageInfo::push_name still carries the current name on every message, which is what a consumer keeping its own contact state reads. The EventKind slot stays, renamed to RetiredPushNameUpdate: the repository's own append-only test caught that removing it shifts every discriminant past it, and that discriminant is an EventInterest bit index consumers persist. LocalChatSettings goes too, unreferenced anywhere. Group IQ addressing is now locked by a test. The IR only started resolving group_jid against g.us in schema 4 -- before it, every w:g2 stanza reported the namespace's base target -- so a request sent to the wrong one looked exactly like a request sent to the right one, and the only symptom was a server that never answered.

Renaming this kind and removing Event::PushNameUpdate and its payload breaks consumers that subscribe to or match the existing public event; the in-tree chat store already references EventKind::PushNameUpdate and Event::PushNameUpdate at storages/chat-store/src/store.rs:130 and :981, so the workspace no longer compiles when that member is checked. Retire the behavior by ceasing dispatch while retaining the deprecated kind, variant, and payload under their original names.

The compile break was real and mine: I checked wacore and src and never storages/. Fixed in 561cea0.
On retaining the names, I'm keeping the removal, deliberately. The crate is pre-1.0 and the repo owner has confirmed breaking changes are acceptable there when the PR carries a migration line, which the body now does.
The reason a deprecated shim is worse than removal here: PushNameUpdate cannot be implemented. Its payload promises old_push_name alongside new_push_name, and there is no contact store in this repository to hold a previous name — every push_name in the tree is our own device's. Keeping the type means keeping a #[deprecated] struct that no code path can ever construct, which reads as "this fires and we'd rather you moved on" when the truth is "this has never fired and never can". A consumer matching that arm today gets silence; after this change they get a compile error pointing at MessageInfo::push_name, which is the value they were actually waiting for. The compile error is the useful outcome.
The frozen-payload contract in AGENTS.md and the Event doc governs how a live payload evolves — sealed with #[non_exhaustive], built through bon, absent fields as Option<T> rather than sentinels — so that adding a field is not a breaking change. It is not a promise that a variant which never dispatched can never be withdrawn.
What is genuinely frozen is the EventKind discriminant, because it doubles as an EventInterest bit index consumers persist. That is why the slot stays as RetiredPushNameUpdate rather than being deleted; persisted masks are unaffected.

With default: None, WireEnum derives Default from whichever catalog variant happens to come first, so a future catalog reorder will silently change MemberAddMode::default() from AdminAdd; the same problem exists for CallLinkMedia at line 174, whose existing default is Audio. These hand-written types had stable defaults before this migration, and generated variants deliberately follow bundle ordering, so declare Some("admin_add") and Some("audio") just as the other migrated enums do.

The removal of the event missed this crate: chat-store both listed the kind in its interest mask and matched the variant, so the workspace no longer built. The branch was dead here too. Contact push names already reach the same table from MessageInfo::push_name on every incoming message, which covers the cases the event never fired for. Also pin MemberAddMode and CallLinkMedia to their protocol defaults rather than letting the first catalog variant stand in, matching the other migrated enums, and correct the Wanted::default doc: the field is declared for every type that has a default, not only where the default trails the catalog order.
`Option<&'static str>` beside the shape left two states expressible that should not be. `None` meant both "the protocol defines no default" and "nobody considered the question", which is the state that let the DecryptFailMode default ride on catalog order in the first place. And a Masks entry could carry a default that the mask emitter silently ignored, since only wire_enum ever read the field. Shape now carries a WireDefault on its two enum arms and nothing on Masks, so an enum always answers the question and a constant set is never asked it. The value stays a wire string because the catalog is read at runtime and there is no Rust type to name it with, but it is now checked against what was emitted rather than against the catalog: a declared default the entry stopped carrying, or one the rename pass failed to place, both fail generation instead of leaving the first variant to stand in. Two tests pin that, one per direction. Output is byte-identical; --check passes against the committed artifacts.

When the status composer's MediaType changes independently—for example, by gaining a status-only kind—the next regeneration will incorrectly add that value to CallLinkMedia, even though this type is used to build and parse call-link stanzas in wacore/src/stanza/group_call.rs. WAWebStatusSetupController is not the call-link protocol, and the commit's identical-variant-set match does not establish that it owns the same wire enum; keep this type handwritten until the actual call-link source is identified, or bind that source instead.

You're right, and this is the one binding in the sweep that was actually wrong. Reverted in b8e202a — CallLinkMedia goes back to hand-written.
I checked the catalog before reverting: WAWebStatusSetupController::MediaType is the only entry whose variant set is exactly {audio, video}, and there is no call-link media enum anywhere in the 403, so there is nothing correct to bind instead. Meanwhile the type builds and parses <call_link> through build_call_link_create, build_call_link_join and parse_call_link_media. So the match was two unrelated two-valued media enums agreeing by coincidence, and a status-only kind added upstream would have landed in call-link stanzas on the next sync.
The underlying mistake is worth naming, because my own PR body advertised it as a feature: matching on variant sets is how a candidate gets found, not how it gets decided. The module has to own the wire format we parse. The other five hold up under that test — MemberAddMode from the group metadata schema, MemberShareGroupHistoryMode from the history-share module, PrivacyUserAction from the privacy job, GROUP_PARTICIPANT_TYPES from the group API, and DecryptFailType from the same WAWebBackendJobs.flow that already owns EncMediaType and the <enc> node — each is used for exactly what its module governs. Only this one crossed a domain boundary.
That rule is now in the emitter's module doc rather than only here, since a comment on a rejected candidate is not where the next sweep will look.

Binding it to `MediaType` in `WAWebStatusSetupController` was wrong. That module is the status composer; `CallLinkMedia` builds and parses `<call_link>` stanzas. The two agree on `audio` and `video`, but a two-valued media enum matching another two-valued media enum is not evidence that one owns the other's wire format, and the catalog carries no call-link media entry to bind instead. Left as it was, a kind added for composing a status would arrive in the call-link type on the next sync. The variant-set match that found the other five is a way to surface candidates, not to decide them; the module has to own the format we parse. That rule now sits in the emitter's module doc, since it is the thing this sweep got wrong.
Dismissed because a newer commit was pushed; Greptile will re-review the current head.

Removing `Event::PushNameUpdate` outright renumbered every variant after it. `Event` derives `Serialize`, and as the note on `AppStateSyncFailed` already says, an index-based format keys variants by position -- which is why new variants are appended rather than slotted in beside their relatives. Deleting one from the middle is the same hazard from the other direction: an event a consumer stored under the old layout would decode as its neighbour. The slot comes back as `RetiredPushNameUpdate`, holding position 29 of 69, with an empty payload. Empty rather than the original fields, because those named an old-name/new-name comparison this repository has no contact store to make; keeping them would keep promising it. Nothing constructs the payload and nothing dispatches the variant. This is the same reasoning already applied to `EventKind`, whose discriminant a consumer persists as an `EventInterest` bit index. The serialized `Event` is persisted state too, and the first pass missed it.

2 participants
Three findings from auditing what the schema-4 catalog (#1309) newly makes checkable. Each is independent; they share a PR because they came out of one sweep.
1. Five more enums have a real upstream name
Found by matching variant sets rather than names, which is what turns up the cases where our spelling diverges (the way
StanzaMessageTypedid forSTANZA_MSG_TYPES). Of 50 hand-written string enums inwacore, 15 match a catalog entry exactly. Five of those match an entry with a genuine upstream name whose module owns the wire format we parse, and move toWANTED:DecryptFailModeDecryptFailType(WAWebBackendJobs.flow)MemberAddModeMemberAddMode(WAWebSchemaGroupMetadata)MemberShareHistoryModeMemberShareGroupHistoryMode(WAWebGroupHistoryShareMode)DisallowedListActionPrivacyUserAction(WAWebSetPrivacyJob)GroupParticipantTypeGROUP_PARTICIPANT_TYPES(WAWebGroupApiConst)Nine of the remaining ten match only a synthetic-named entry (
ENUM_DARK_LIGHT,ENUM_APPROVED_INREVIEW_NONE_REJECTED, …), which the emitter refuses by design. That is worth stating plainly: most of the 15 stay hand-written for a reason the tooling enforces, not for lack of trying.All public paths are preserved by re-export, so no caller changes.
The tenth is the interesting one: a variant-set match is not an identity
CallLinkMediawas in this list until review caught it. It matchesMediaTypeinWAWebStatusSetupController— the status composer's module — while the type itself builds and parses<call_link>stanzas. Both carry exactlyaudioandvideo, and the catalog holds no call-link media entry to bind instead, so there was nothing correct to swap it for.Two two-valued media enums agreeing on their values is not evidence that one owns the other's wire format. Had it shipped, a kind added upstream for composing a status would have arrived in call-link stanzas on the next sync. So it stays hand-written, and the rule that decides these — a variant set is how a candidate is found, the module is what decides — now lives in the emitter's module doc, since a comment on the rejected candidate is not where the next sweep would look.
This also needed
#[wire_default]in the emitter, and that is the other trapThe catalog's variant order is not ours.
DecryptFailModeis declared here asshow, hide; the catalog carrieshide, show. TheWireEnumderive takes the first variant asDefaultwhen nothing says otherwise, so generating from catalog order would have silently flipped the default fromShowtoHide— no compile error, no failing test, since nothing calls::default()directly today.The default is now part of
Shape, so the combinations that do not exist cannot be written down: an enum always answers the question and a mask set is never asked it.This replaced an
Option<&str>sitting beside the shape, whereNonemeant both "the protocol defines no default" and "nobody considered the question" — the second being exactly the state that let the ordering matter — and where aMasksentry could carry a default that onlywire_enumever read, so the mask emitter ignored it silently.The value stays a wire string because the catalog is read at runtime and there is no Rust type to name it with. What is checked is stronger than before: the assertion now runs against what was emitted, not against the catalog, so a declared default the entry stopped carrying and one the rename pass failed to place both fail generation instead of leaving the first variant to stand in. Two tests pin it, one per direction.
2.
Event::PushNameUpdatepromised something this client cannot deliverThe payload declared
old_push_nameandnew_push_nameand nothing in the repository ever dispatched it. A consumer registering a handler for contact push-name changes got silence.My first plan was to fill it in, since
parse_message_infoalready puts thenotifyattribute intoMessageInfo::push_nameon every message. That does not work: there is no contact store in this repository — everypush_namein the tree is our own device's. There is nowhere to hold the previous name, soold_push_namehas no source. A per-connection map would be worse than nothing, firing inconsistently across reconnects and re-announcing every contact after each one.So the event is retired rather than implemented. A contact database is downstream application state, not protocol state, and
MessageInfo::push_namealready hands a consumer the current name on every message — which is all this layer can honestly offer.Retired in place, because two positions here are persisted state
Both the
EventKindvariant and theEventvariant keep their slots, renamedRetiredPushNameUpdate. Neither is a source-compatibility concession; both are about data already written down:EventKind— the repository's ownevent_kind_discriminants_are_append_onlytest caught that deleting the variant shifts every discriminant past it down by one. That discriminant is anEventInterestbit index a consumer persists or transmits, so removing it would silently re-point every stored mask.Event— caught in review, and the sharper of the two.EventderivesSerialize, and as the note onAppStateSyncFailedalready says, an index-based format (bincode, postcard) keys variants by position, which is why new variants are appended rather than inserted. Deleting one from the middle is the same hazard from the other direction:PushNameUpdatesat at position 29 of 69, so an event a consumer stored under the old layout would decode as its neighbour. Verified positionally — 69 variants before and after, position 29 the only index whose name differs.The retained payload is an empty sealed struct rather than the original fields. Those fields named a comparison this repository cannot make, and keeping them would keep promising it; the empty struct holds the slot without claiming anything. Nothing constructs it and nothing dispatches the variant.
storages/chat-storedid consume the variant, which I missed on the first pass and CI caught. Its handler is removed, and the crate loses nothing:apply_messagealready upserts contact push names straight fromMessageInfo::push_nameon every incoming message, so the table it wrote to is still filled by a path that actually runs.LocalChatSettingsgoes too — the whole struct was unreferenced.Migration
Breaking at the source level, and taken deliberately while the crate is pre-1.0. Persisted
EventInterestmasks and serializedEventvalues are not affected — that is the point of retiring in place.Event::PushNameUpdate(..)renames the arm toEvent::RetiredPushNameUpdate(..)or, better, drops it — the variant can never fire. Read the current name fromMessageInfo::push_nameon the message events you already handle; if you need change detection, diff it against your own contact store, which is where the previous value lives.EventKind::PushNameUpdatein an interest set, and to thePushNameUpdatepayload type, which is now an empty struct.LocalChatSettingshas no replacement. It modelled nothing on the wire.3. Group IQ addressing is now locked by a test
The IR only began resolving
group_jidfromg.usin schema 4. Before that everyw:g2stanza reported the namespace's base target ofs.whatsapp.net, so a request addressed to the wrong one of the two was indistinguishable from a correct one, and the only symptom is a server that never answers and a caller that waits out its timeout.I audited our specs against the resolved targets by hand. Result: clean, and one suspicion of mine was wrong. I thought
GetGroupInviteLinkIq's reset was misaddressed because the IR listsresetGroupInviteCodeunderg.us— but that builder has two entries in the same module: onegroup_jidwith an empty<invite/>, which is ours and correct, and oneg.uswith a code, which is a different call we do not implement.GetGroupInviteInfoIqalready targetsg.uscorrectly.The value is the test, not the finding:
group_requests_are_addressed_the_way_the_ir_resolves_thempins fourg.usspecs and fivegroup_jidones. It is a regression lock rather than a derivation — the IR is not available at test time — and its doc says so.Also worth knowing
PrivacySensitiveTypedeclares one value (1) where the catalog's matching entry carries two (0and1). Probably fine, since this client only ever sends1, but it is the one place the sweep found us modelling a strict subset. Not touched here.Validation
