Best possible solution:

Land the route-aware dedupe helper after adding a single active changelog entry and waiting for required checks, keeping normal replies and follow-up/media wake delivery aligned on the same same-route suppression rule.

Do we have a high-confidence way to reproduce the issue?

Yes. On current main, call resolveFollowupDeliveryPayloads with a payload whose text or media matches sentTexts/sentMediaUrls while sentTargets points to another provider or target; the current function filters the content before route metadata can preserve the requester-facing reply.

Is this the best way to solve the issue?

Yes, with the changelog follow-up. Centralizing the decision into shouldDedupePayloads and suppressReplies is the narrow maintainable fix because both normal replies and follow-up delivery can share the same route-aware rule while preserving legacy content dedupe when target metadata is absent.

Full review comments:

• [P3] Add the required changelog entry — src/auto-reply/reply/reply-payloads-dedupe.ts:208
  This changes user-visible messaging reply delivery: cross-target message-tool sends no longer suppress follow-up text/media replies. OpenClaw policy requires an active CHANGELOG.md entry for user-facing fixes before landing, but this PR does not update the changelog.

What I checked:

• PR state: The public PR API shows this PR is open, ready for review, mergeable, labeled maintainer, and at head SHA 97dae1f. (97dae1f1c13d)
• Current main follow-up bug: Current main applies filterMessagingToolDuplicates and filterMessagingToolMediaDuplicates before shouldSuppressMessagingToolReplies, so a cross-target sent text/media match can still erase the follow-up reply before route metadata is considered. (src/auto-reply/reply/followup-delivery.ts:65, 7b3dfbf21407)
• Current main partial behavior: Normal final replies already use route-aware suppression and only content-dedupe when the messaging tool target is same-route or target metadata is absent, which the PR extends to follow-up delivery. (src/auto-reply/reply/agent-runner-payloads.ts:191, 7b3dfbf21407)
• PR helper: The PR adds resolveMessagingToolPayloadDedupe, returning separate shouldDedupePayloads and suppressReplies decisions from the existing route-aware suppression helper. (src/auto-reply/reply/reply-payloads-dedupe.ts:208, 97dae1f1c13d)
• PR follow-up fix: The PR changes follow-up delivery to resolve the route-aware dedupe decision before filtering text/media, and only applies content/media filtering when shouldDedupePayloads is true. (src/auto-reply/reply/followup-delivery.ts:63, 97dae1f1c13d)
• PR coverage: The PR adds follow-up tests proving text and media sent by the messaging tool to another provider/target are preserved for the requester-facing follow-up reply. (src/auto-reply/reply/followup-delivery.test.ts:43, 97dae1f1c13d)

Likely related people:

• steipete: Recent history for the central route and auto-reply payload surfaces includes route-helper publishing, route normalization, silent voice payload preservation, block-stream media dedupe, and the follow-up delivery seam, beyond this PR authorship. (role: recent maintainer and route/dedupe refactor owner; confidence: high; commits: e27c32b9b0d9, 387668263559, 28bf71d74b06; files: src/auto-reply/reply/reply-payloads-dedupe.ts, src/auto-reply/reply/agent-runner-payloads.ts, src/auto-reply/reply/followup-delivery.ts)
• vincentkoc: Current local blame is rooted in a recent Vincent Koc commit, and GitHub history shows follow-up type/import and dedupe-helper split work in the same reply surface. (role: adjacent reply/follow-up maintainer; confidence: medium; commits: 7f58e89731, 159e6bc09931, 125e778fe618; files: src/auto-reply/reply/reply-payloads-dedupe.ts, src/auto-reply/reply/followup-delivery.ts, src/auto-reply/reply/reply-payloads.test.ts)
• mcaxtr: Recent history for agent-runner-payloads.ts includes outbound media normalization and final media delivery work that overlaps the media-dedupe side of this PR. (role: adjacent media reply maintainer; confidence: medium; commits: 18c98316f7ac; files: src/auto-reply/reply/agent-runner-payloads.ts)

Remaining risk / open question:

• The required active CHANGELOG.md entry for this user-facing fix is still missing.
• Some GitHub checks for the exact head SHA were still in progress during review, so required checks should finish before merge.
• The protected maintainer label means explicit maintainer handling is still required even after the mechanical changelog repair.
