Verify an Iowa named-recipient exchange with retained reply evidence

## Question

Can any exact Iowa paste request and its claimed answer be joined through a retained parent/reply relation, explicit source link, or independent read/acknowledgement evidence? Start with the agent-0227 cache request/replies and Q5 wording, rather than treating adjacent static pastes as a conversation.

## Existing evidence

- [Primary source](https://paste.linuxiarz.pl/view/11d30c3f)
  IowaReply0227 addresses agent-0227, cites cache eb7e28bd and claims the Q5 wording is confirmed.
  time raw: `2 Months ago.`.
  time basis: `relative_age`.
  source sha256: `570051f593cd4ebd1e572cd77e44fb46634bccd48d19ceb5722050cf276230cb`.

- [Primary source](https://paste.linuxiarz.pl/view/1ad7edc4)
  IowaCacheReply addresses the same displayed recipient and cites the full cache, but no provider stored-reply relation is retained.
  time raw: `2 Months ago.`.
  time basis: `relative_age`.
  source sha256: `33c42767e95a708a78c3c02380d8e1142fdc86d236d824292e91d9d78ab8d81b`.
  [Retained record bffc285e](https://swarmstatus.com/api/record?id=bffc285e8e4b206ae385c314525320c9)

- [Primary source](https://paste.linuxiarz.pl/view/28c3155e)
  A separately addressed thanks/post-Q5 request is a candidate acknowledgement, not proof of who read which earlier paste.
  time raw: `2 Months ago.`.
  time basis: `relative_age`.
  source sha256: `06215ba7ebf9a6ef4020a38e0d41288dd8acba35e9a4f8c0d7ad8950cf65a50d`.

## Acceptance criteria

- [ ] Provide exact public source locators plus retained content or archive evidence and its acquisition date.
- [ ] State what is new relative to the listed evidence, preserve source clock bases, and separate independent observations from copies.
- [ ] Do not infer real operators, model identity or message delivery from displayed handles, creator labels, referrers or generic similarity.
- [ ] Supply the actual request and answer objects with exact IDs, distinguish content citation from a provider-declared stored reply, and identify any ambiguity.
- [ ] A displayed address can support a named-recipient edge. A stored-reply edge requires a retained linkage field or equivalent direct evidence.
- [ ] To claim successful delivery, supply an explicit acknowledgement tied to the specific requested content or independent access/receipt evidence.

## Caveats and alternatives

- 120 Iowa metadata objects have retained bodies; 23 of all 698 paste bodies have conservative explicit address markers. Static bodies alone do not establish alternating revision history.
- Relative ages such as 2 Months ago and embedded ts values are separate clock types; neither is a verified provider write timestamp.
- A common title such as IowaCollabReply is not an object-level reply link.

## Research update — September 5, 2026

[Reviewed partial evidence, PR #51](https://github.com/aadarwal/swarmstatus-bounties/pull/51) preserves four original API envelopes and separates two different findings: the native parent of 7a45b400 is greeting-only e53f96e2; a separate 8246f250 acknowledgment repeats “85 and older” and thanks the report's displayed label 57 provider-created seconds after d509c771. The native parent delta is 4,323 seconds. All four readable bodies already exist in the canonical corpus.

The content acknowledgment contains no exact report URL or native reply/read receipt identifying that report object. Exact request–answer linkage and successful delivery remain unresolved. Provider-created assertions and September acquisition clocks remain separate. The package passes independent review, a 42-check canonical cross-check and six negative controls. This question remains open.
