How this group was decided

Every step below is a pure function of the event. The same event always produces the same group.

  1. 1 · Parse the stack trace

    4 frames parsed, 4 belong to the application. Only those decide the group — the same bug reaches the runtime through different framework paths depending on the request.

    • in-appsrc/indexer/build.js.buildIndexsrc/indexer/build.js:142
    • in-appsrc/indexer/queue.js.processQueuesrc/indexer/queue.js:88
    • in-appWorker.runsrc/worker.js:37
    • in-apptask_queues.<anonymous>task_queues:95

  2. 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.

frame=src/indexer/queue.js#processQueue
frame=Worker#run
frame=task_queues#<anonymous>

  3. 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.
