Completed catalogue decisions are recorded separately from technical inspection and scientific validation. Access and metadata evidence retain their original dates and scope.
Completed catalogue assessment
- Eligibility decision
- Include · Retained Supporting
- Assessment date
- 28 September 2026
- Decision reason
- Three original BIPAD alerts retrieved; timestamps for start, creation and embedded observations are distinct. Source attribution is DHM. These administrative records do not establish warning dispatch, receipt, evacuation or complete alert history. This file documents source/provenance or administrative history.

- Preserve alert start, database creation and embedded observation times separately; obtain archived issuance/update evidence before reconstructing the warning timeline.
- Keep the description water level separate from the later embedded reference measurement; they are not a single issuance-time observation.
- Establish component-specific reuse terms before redistributing upstream observations or alert contents.

- What the warning chronology establishes
- Start, creation, expiry and the embedded measurement are distinct. Embedded records are later than start and may reflect updates. No dissemination, delivery, receipt or evacuation evidence supplied.Review Assessment · source · Interpretation of the distinct native timestamp fields; no dissemination or recipient evidence retrieved

- Public BIPAD alert attributed to DHM. Its stated start is 2026-08-26T14:00:00+05:45; database creation is 2026-08-26T14:05:09.955498+05:45. The embedded reference observation is 2026-08-26T09:05:00Z, 50 minutes after the alert start. Description and embedded reference water levels differ. These fields must not be combined into one issuance-time measurement. Expiry is 2026-08-26T15:05:04.007106+05:45; expiry is not a proven return to safe conditions.
- No component-specific open licence established. Public API access does not establish redistribution permission. Only descriptive metadata and source links are published; retrieved source responses remain private.
- Public access and structural inspection do not establish scientific accuracy; station points and alert demography are not a measured flood footprint or affected-person count.
