Congrats on the first fork-local fix landing — the CI-red-on-mentions diagnosis in PR #96 is a real catch.
The defect you closed is the same failure mode we've been measuring on the Nostr identity plane, and it
may be worth one design step further.
Your lenient-admission branch read "agent missing from a send-time revalidation" as "never listed, safe to
mention", and a relay-revoked agent matched that same empty shape — so revocation was silently re-admitted.
The fix carries directory provenance so "revoked" and "never listed" stay distinguishable. That's correct
and we corroborate it: on the ack side we run a 19/19 pass (mobile mention_ack_store_test.dart, kind:44102)
and our throttle/drop work (PR block#6259 / block#6578 lineage) reaches the same conclusion — "absence is not a safe
negative" is the exact phrase a fork of Block's own buzz (coldcanuk/hush, closing our issue #87) affirmed.
Open question we'd genuinely like your read on: rather than shrinking the ambiguity window with cached
provenance, has your fork considered making revocation a POSITIVE-NEGATIVE — i.e. the relay publishes an
explicit tombstone (expired/revoked kind:30315 line, or a revocation event) so a missing record is
unambiguously "never listed", never "maybe-revoked"? Cached provenance is monotonic-but-local; a tombstone
is wire-durable and survives the same same-send double-revalidation hole from the first time, not as a
post-hoc cache fix.
No pressure on this specific PR — it's correct as merged. Just flagging the axis because we'd fork a
garden-path ourselves if we shipped a local-cache-only answer. Happy to cross-check any tombstone design
against the 19/19 ack matrix we already run.
