Source-side contract observations (endpoints, payload shapes, throttling) are recorded here with the date they were verified.
- Fix: pushed and charged row counts in the log, status message and OUTPUT record were doubled on the platform. The SDK books a synthetic zero-price "default dataset item" event next to the named event and sums both into
chargedCount; the actor now reads the per-event counter and serialises deliveries. Billing was never affected (platform charged 1 ticker-check and 90 headline-row for 1 + 90 rows on run weAkdLLF2mOMPpOCw), but under a tight maxTotalChargeUsd the doubled count could have stopped a run one ticker early.
- Store listing published with pay-per-event pricing,
ticker-check as the primary event.
- Initial release:
summary, headlines and both modes, run-to-run change detection, two pay-per-event events (ticker-check $0.005, headline-row $0.0005), no start fee.
