- #62860: \[Bug\]: Inbound dedup marks messages seen before processing — a failure after the mark drops the platform redelivery (silent message loss)
- #66997: fix(feishu): admission-rejected messages are dropped silently at DEBUG after the seen-store is already persisted
- PR #62861: fix(wecom): release inbound dedup claims when the handler fails, without re-running completed turns

These issues and fixes concern inbound message deduplication logic that marks messages as seen before processing is complete, risking silent loss if a failure occurs mid-flight. Related concerns include suppressed or low-visibility logging when messages are rejected or dropped.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.39`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
