actor_outbox_response_for/3 in http_server.erl now reads ?since=
from the query string before paging:
Q = field(request_query, Cfg),
Filtered = case parse_since(Q) of
nil -> Entries;
SinceCid -> backfill:since_cid_entries(SinceCid, Entries)
end,
Slice = page_slice(Filtered, Page),
...
New helpers:
parse_since/1 — scan query for since=<Cid>, value is the
binary up to next & or end-of-binary. nil
when absent.
scan_param/2,3 — generic 'find Name=Value anywhere in &-sep
query'. Used for since= today; could be
factored over parse_page=.
skip_to_amp/1 — walk past the next & for the iteration step.
Order-independent: ?since=X&page=2 and ?page=2&since=X both
work. Unknown cid -> backfill:since_cid_entries returns []
-> empty page -> body degrades to tip-only shape (Step 4d
back-compat).
Three new cases in http_multi_actor.sh (44/44 total):
- ?since=<first cid> filters out the first publish, leaving
2 of 3 items in the paged response
- ?since=<unknown cid> -> empty page; body has tip but no
item: lines (tip-only degrade)
- ?since=<cid> + ?page=1 combined — pagination still applies
to the filtered list
Latent issue surfaced + fixed in passing: http_multi_actor.sh
was missing follower_graph + delivery + backfill module loads
(outbox has depended on follower_graph + delivery since Step 7c
and now backfill from 9a). Added all three with epoch 100/101/
102 to match the c6b49200 fix-up pattern. 41 existing tests now
also exercise the live path through outbox:publish without
crashing on missing module deps.
