Marty: "if it's just gonna keep running, why would anyone use impressions to
place the ad at all?" He is right, and my previous answer — calling the
over-delivery a bonus — papered over a real flaw.
Banner placements on this network have no cap. Left alone, 2,500 impressions
buys an ad that runs until expiry, which makes the allowance decorative and
the whole level ladder (2,500 at Scintilla to 150,000 at Corona) worth
nothing. Nobody would ever spend the larger allowance for an identical
outcome.
Two changes so the impressions are genuinely the thing being spent:
sweepCompleted() deactivates any campaign that has served its purchased
amount. Runs 90s after boot and every 15 minutes, batches its stat reads, and
only touches campaigns that are live, un-stopped and provably at or past what
was bought. Nothing is refunded — they delivered in full. It re-reads the
ledger after the network calls, since deactivating takes real time and
another member may have launched in that window.
New campaigns get days:30 instead of days:365. The allowance is monthly, so a
campaign outliving the month it was paid from is the same bug by another
route. Belt and braces — whichever ends it first.
Copy corrected too: "still serving as a bonus" became "served in full —
closing out", and the footnote now states plainly that a campaign ends when
it has served what was bought.
