No SAWS PNG passed exact page/image identity, 73-frame contract, PNG type/size, 30-hour update, plotted-domain, resolved-spot, and market-membership validation. Elands Bay is north of the live Saldanha map bounds (32.4°S–33.55°S) and is not assigned; only resolved Yzerfontein lies inside the plotted domain.
CSIR WaveNet live west-coast pages expose plots as regenerated PNG images rather than reusable numeric observations. Cape Point, Table Bay, Saldanha Bay, and Muizenberg pages were reachable, but no value is OCR-scraped or relabeled as station data.
SANHO publishes live monthly Cape Town, Simon's Town, and Saldanha PDF tide tables with station-specific chart-datum information, but the official page states that the tables may not be reproduced without written permission; predictions are withheld.
No separate tide response passed station identity, coordinates, distance, chart datum, timezone, units, prediction timestamps, and reuse validation; SANHO PDFs are not substituted under a third-party label.
