📝 WalkthroughWalkthroughChangesTrigger and approval APIs
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The PR adds Slack approval matching, but the current implementation can accept approvals from messages posted by another app and can recover approvals from matching block IDs without the required metadata marker; ambiguous event parsing may also misidentify the actor or item. This creates a concrete unauthorized-approval risk, so the PR is not safe to merge until these checks are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

39-61: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winCover the two single-source decode paths.
The suite covers metadata plus blocks, and redacted metadata plus blocks. It does not cover metadata with no blocks, and it does not cover blocks with no metadata. The second case is the path I flagged in
packages/delivery/src/slack-approval.ts(lines 151-174). Add both cases so the intended trust boundary is pinned by a test.💚 Proposed extra cases

Inline comments:
In `@packages/delivery/src/slack-approval.ts`:
- Around line 191-203: Update matchSlackApprovalReaction to verify that the
reacted message was authored by the application, using an optional author-check
configuration and requiring that check for approval matching; preserve the
existing actor, emoji, and timestamp validation and return null when the message
author does not match.
- Around line 151-174: Update the approval recovery logic around metadataMatches
and matchingBlock so block-only recovery is accepted only when
metadata.event_type contains the expected approval marker; reject missing or
mismatched event types even when block_id matches. First verify the Cloud and
Relayfile readers preserve metadata.event_type through parsing, then apply the
stricter condition without changing matching metadata/block validation.
In `@packages/delivery/src/slack.ts`:
- Around line 118-121: Update the item-type gate near firstSlackRecord to accept
only an explicit “message” value, rejecting missing or other types; update the
event-wrapper fixture in the Slack tests to include type: “message”.
- Around line 123-131: Update actor resolution near matchSlackApprovalReaction
to use layer-major lookup, trying user and user_id within each candidate record
before moving to the next record, so actorId comes from the same layer as
reaction. Add and use a firstSlackStringOfKeys helper alongside the existing
Slack parsing helpers, while preserving the existing required-field validation.
