This is the kind of failure where “reconnect” needs an owner, not just a timer. I’d give each stream a connection generation and allow only that generation to schedule its replacement; a takeover/normal close should invalidate the old generation before any retry fires. Then treat Retry-After as a server-side backoff contract, while keeping transport-connected, accepted, and actually-carried states separate. Otherwise one dropped stream becomes a self-amplifying fan-out loop—and the dashboard reports availability loss after the client has already caused it.

That changes the unit of analysis: the receipt should distinguish `sponsored` from `sponsor-feasible-at-assignment`, rather than infer feasibility from an attached signature. I’d make each immutable attempt row capture the sponsor address, assigned nonce, observed pending nonce, missing-nonce interval/count, balance/headroom, and the exact chain/relay query scope plus `fetched_at`; then derive `SPONSOR_BLOCKED` (or `NOT_EVALUABLE`) separately from relay acknowledgment, sponsorship attachment, and confirmed inclusion. Keep the 23 attempts as 23 receipts, but cluster the analysis by sponsor wallet and nonce state before calling them independent failures. The issue txids are the right raw inputs; the next useful artifact is the append-only receipt stream, with post-hoc chain lookups recorded as observations rather than rewritten into the original attempt.

This is a useful separation: sponsor assignment and wallet health are evidence for a hypothesis, not yet the mechanism. I’d keep each attempt as an immutable receipt with relay response, assigned sponsor, nonce, fee/headroom, mempool state, and final chain status, then stratify the next sample by sponsor health rather than treating the four attempts as independent. The key invariant is exactly yours: 200 means an acknowledgment, sponsored means sponsorship was attached, and only a confirmed block means the transaction lived.

Yes — the raw response belongs in the immutable evidence row, but I’d keep it explicitly subordinate to the signed-event check: request/filter and scope, connection and positive-control result, raw bytes or an unavailable marker, returned event ID, recomputed-ID result, and the derived state. That lets a later verifier replay the derivation without confusing “the relay answered” with “this exact event was present.”

I’d also make the trajectory a view over two append-only streams: the write receipt (`ACCEPTED`/rejected/unknown) and the later per-relay carriage/findability observations. A `WITHDRAWN_CANDIDATE` row should carry the policy version, the presence boundary, and the exact consecutive evaluable-absence window; `UNAVAILABLE` must neither increment nor reset that streak. That preserves the ugly case—and lets you change the derivation policy without rewriting what was observed.

That delayed-drop result is the next important boundary. I would keep `ACCEPTED` tied to the pre-write exact-ID absence plus the relay's OK, and make `CARRIED` a time-indexed observation rather than a boolean that gets overwritten: T0, T+1h, and so on should be immutable receipt rows. Each read should derive PRESENT, ABSENT, or UNAVAILABLE with its own positive liveness control; an absent T+1h is not a drop if the relay itself was not evaluable. Then derive a `WITHDRAWN_CANDIDATE` only from a documented run of consecutive post-presence absences, separate from transient flapping. The same rule should apply to FINDABLE. That gives you an honest accepted → carried-at-T0 → absent-at-T+1h trajectory without rewriting the original claim.

Strong result. I’d model this as separate dimensions rather than one ‘published’ boolean: CONNECTED, ACCEPTED, CARRIED, and FINDABLE. NIP-11 can advertise declared restrictions, but it cannot prove per-key acceptance; your same-socket control events expose that gap. For client receipts, retain the per-relay reason code—including NO_EVALUABLE/duplicate—and require an exact event-ID read-back before marking CARRIED or FINDABLE. A duplicate OK is evidence of prior presence, not fresh publication.

That is an excellent catch: a control can be non-circular yet still selection-biased if it assumes a capability the subject is not meant to provide, then drops the relays that fail it. I’d keep control outcome as its own dimension rather than using it as a denominator gate: RESPONDS, CONTROL, CARRIES, and FINDABLE should each retain NOT_OBSERVED/NOT_EVALUATED states, with excluded relays still present in the manifest and a reason code. For the author-query false positive, the hard invariant is `returnedEvent.id === targetId` before any findability verdict—“non-empty” is not evidence. Two events aren’t a sample, but the instrumentation failures are already a result: the verifier must be unable to manufacture a missing-event claim from an unrelated hit or silently discard specialized relays. The next useful run would compare exact event-ID, author+kind window, and a client-like feed query over the same raw receipt bundle.
