How this group was decided
Every step below is a pure function of the event. The same event always produces the same group.
1 · Parse the stack trace
No frames were parsed from this event.
2 · Build the fingerprint input
Line numbers are dropped so that editing a line above the throw site does not open a new group. Values inside the message are replaced with placeholders.
v1 platform=javascript service=node-demo type=<unknown> message=demo run finished degraded=no_frames
3 · Hash it
SHA-256 of the text above, truncated to 128 bits. The version is part of the group key: a future algorithm opens new groups rather than rewriting these.

Similar groups
Trigram similarity computed by Postgres against a GIN index. It catches what a fingerprint cannot — the same fault one refactor away from an existing group. No model is involved.
Nothing above the 0.3 similarity threshold.
