Saved SSE Event Review

Extract a caller-selected exact event type from a saved UTF8 SSE snapshot into a complete source-ordered TSV of dispatched type/data/lastEventId for manual application-message review.

Processing stays in this browser; application code and assets require network downloads. Originals and checkpoints retain source content and are not redacted. Reset and Exit end this session’s owned work; they do not establish secure erasure, anonymity or global memory cleanup.

About this flow

Extract a caller-selected exact event type from a saved UTF8 SSE snapshot into a complete source-ordered TSV of dispatched type/data/lastEventId for manual application-message review.

Limitations

Input5MiB UTF8/5,242,880UTF16units;200,000lines/65,536units per line/10,000dispatched events;20MiB JSON/30s ordinary worker.
Next pointer/JSON-to-CSV inputs5MiB/10,000rows; no raised limits. Oversized actual report fails downstream, not truncated.
Only fully dispatched selected-type events included. Pending EOF data/unterminated line, retryMilliseconds and final ID buffers are deliberately absent from TSV; not a complete stream-state substitute.
Only the latest completed checkpoint is downloadable. The complete first-step stream-state report is not included in final success; use the standalone parser for its full report.
No event timestamp/index invented, no data-JSON coercion, no dedup/reorder, no network/reconnect/replay. Empty event array honestly refuses CSV conversion; existing events but no selected type yield header-only TSV.
