Document MessageContext gaining ephemeral_expiration/comment_target (whatsapp-rust#1391)

[jlucaso1]

Summary

Documents oxidezap/whatsapp-rust#1391, a fix for a regression introduced by #1390: MessageContext::from_inbound copied only message and info from the dispatched InboundMessage, so a bot handler no longer saw the chat's disappearing-message timer (ephemeral_expiration) or a newsletter comment's parent post key (comment_target) — #1390 had moved both off the shared MessageInfo onto InboundMessage, and MessageContext was never updated to follow.

• api/bot.mdx — documents the two new MessageContext fields, and which constructors populate them: only from_inbound sees the stanza-derived event, so from_arc/from_parts always leave both None.

Documenting MessageContext's new fields accurately meant the surrounding docs needed to agree on where ephemeral_expiration/comment_target actually live, which they didn't — several pages still showed them as info.ephemeral_expiration / info.comment_target (stale since #1390, which was never separately documented). Fixed those in the same pass rather than adding new content next to text that contradicts it:

• concepts/events.mdx — moves the two fields from the shown MessageInfo struct to InboundMessage, and adds a breaking-change note explaining the move and cross-linking MessageContext.
• guides/receiving-messages.mdx, guides/sending-messages.mdx, guides/communities.mdx — update code samples and prose that destructured info.comment_target/info.ephemeral_expiration to read the fields directly off InboundMessage instead, and point at MessageContext::ephemeral_expiration/comment_target for bot handlers.

No changelog entry included, per repo convention (human-authored only).

Test plan

• Verified the new MessageContext fields and their population rules against the merged diff of oxidezap/whatsapp-rust#1391 (src/bot.rs).
• mint broken-links (not run in this environment — no local Mintlify CLI).

Summary by cubic

Documents the new ephemeral_expiration and comment_target fields on MessageContext, and fixes stale docs that still showed both fields living on MessageInfo.

Changes

• api/bot.mdx documents both fields and that only from_inbound populates them; from_arc and from_parts leave them None.
• concepts/events.mdx moves both fields from the shown MessageInfo struct to InboundMessage, noting the move avoids an Arc::make_mut copy of the shared struct.
• guides/receiving-messages.mdx, guides/sending-messages.mdx, and guides/communities.mdx update code samples to destructure the fields directly from InboundMessage instead of info.
• Bot handlers should read the fields as ctx.ephemeral_expiration / ctx.comment_target.

^{Written for commit cbf9101. Summary will update on new commits.}

Summary by CodeRabbit

• New Features

  • Message events and contexts now expose ephemeral expiration and comment-target metadata directly.
  • Channel comment handling uses the inbound event’s comment target.

• Documentation

  • Updated message-receiving and message-sending examples to reflect the new metadata locations.
  • Clarified which metadata is available through inbound events and message contexts.

📝 Walkthrough

Walkthrough

The documentation moves ephemeral_expiration and comment_target from MessageInfo to InboundMessage. MessageContext now exposes both fields. Constructor behavior and receiving, community, and sending examples reflect the new API.

Changes

Message metadata relocation

Layer / File(s)	Summary
Metadata fields and constructor behavior concepts/events.mdx, api/bot.mdx	Documents the new fields on InboundMessage and MessageContext. Documents that only from_inbound populates them.
Receiving metadata guidance guides/receiving-messages.mdx	Separates MessageInfo metadata from InboundMessage metadata in descriptions and examples.
Message handling examples guides/communities.mdx, guides/sending-messages.mdx	Updates comment-target and ephemeral-timer examples to read fields from InboundMessage.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 419bb

This documentation-only change does not alter product behavior or runtime code. The remaining follow-up is limited to improving wording and consistency, so no actionable merge-blocking risk remains after normal review.

Poem

A rabbit hops through fields anew
InboundMessage holds the view
MessageContext follows near
Old shared copies disappear
Examples now point true

Inline comments:
In `@api/bot.mdx`:
- Line 1013: Rewrite the documentation around MessageContext, from_inbound,
from_arc, and from_parts into short direct sentences with one fact per sentence.
Use active voice and address the reader as “you”; explicitly tell readers to use
from_inbound when they need event-derived ephemeral_expiration and
comment_target, while noting that from_arc and from_parts leave both fields
unset.

In `@concepts/events.mdx`:
- Line 940: Rewrite the breaking-change note into short, single-idea sentences
using active voice and directly addressing “you.” Separate the migration
guidance for reading fields from InboundMessage, the MessageContext behavior,
and the implementation/performance rationale; preserve all technical details and
examples while removing the current dense sentence structure.

In `@guides/receiving-messages.mdx`:
- Around line 158-160: Rewrite the descriptions of unavailable_request_id and
InboundMessage::comment_target in active, direct second-person language, making
“you” the subject where appropriate. Keep each field’s behavior in focused,
single-idea sentences while preserving the existing correlation and threading
details.
- Line 130: Align the lifecycle documentation for ephemeral_expiration so it
identifies one accurate source and availability point, removing the conflicting
before-decryption claim and the contextInfo.expiration discrepancy. Update
guides/receiving-messages.mdx lines 130-130 and guides/sending-messages.mdx
lines 718-718 with the same corrected explanation; both sites require direct
changes.

In `@guides/sending-messages.mdx`:
- Line 310: Rewrite the documentation sentence near Event::Messages and
InboundMessage::comment_target in direct second-person active voice: state what
you receive in one sentence, then state separately where you can read the parent
post key.

Apply the same fix in `@guides/communities.mdx` at line 362: The same passive,
indirect guidance appears in the communities guide and needs the same rewrite.
