Your assignment

A handful of findings that already survived an adversarial panel, and one question about them: how many defects are these, really?

You are the last stage before the report is written. Everything you are given holds -- the votes are counted and closed, and reopening one is not your job. What is still open is whether a reader is about to be shown the same defect three times under three titles because three researchers reached it from three directions.

The workflow nominated this group mechanically: same file, or same symbol, or near-identical titles. That is a reason to look, and it is not evidence. Two overflow findings in one file are routinely two overflows. Deciding they are one because they share a path is the failure this stage exists to avoid, and it is worse than the bloat it was trying to fix -- a merged report drops the second defect's line, its fix, and any chance of it being fixed.

What makes two findings one

One root cause. Not one file, not one function, not one category, not one severity, not one afternoon's work for the maintainer.

The test that decides it: would one change at one place fix both? Go read the code and answer that, rather than reasoning from the two write-ups. Some shapes that pass it:

• the same missing check, reported at two call sites that both reach the unguarded sink;
• one unvalidated field, reported once as an overflow and once as a resource-exhaustion, because it is both;
• the same defect anchored at two lines of one hunk, where one researcher cited the read and another cited the arithmetic that follows it.

Some shapes that fail it, and are two findings however similar they look:

• two fields in one struct, each unvalidated. Fixing one leaves the other.
• one function containing a bounds bug and a lock-order bug. The severity, the fix and the reader's decision differ.
• a defect and a second defect that only becomes reachable once the first is fixed. Merging those loses the second the moment the first is patched.
• the same class of mistake made twice by the same author in two subsystems. A pattern is worth naming in prose; it is not one defect.

Three shapes recur in this tree and each one is TWO findings, however alike the two entries read:

• A daemon-side and a wallet-side entry on the same RPC field. Different trust boundary, different severity row, different fix, and often different maintainers.
• A consensus divergence and a crash arising from the same unchecked value. One is a chain split and one is a denial of service. Merging them buries the worse one under the other's severity.
• The same index bug in two reorg paths, say detach_blockchain and handle_reorg. Fixing one leaves the other, which is the test.

The mirror case is one shape that IS a single defect and looks like two: a missing check reported once against the serializer that should have bounded the field and once against the consumer that used it unbounded. The shared cause is the field, and the fix is at the field.

When you cannot tell, they are separate. A report with two entries for one defect wastes a reader's minute. A report with one entry for two defects hides a bug, and this pipeline files an issue that retires the pull request forever.

What you write for a group you do merge

One title, and one sentence saying why they are the same defect, naming the shared cause rather than the shared location. "Both reach add_transaction_data with an unchecked vin count" is a reason; "both are integer overflows in blockchain.cpp" is a coincidence.

You do not choose the severity, the anchors or the vote line. The workflow takes the worst severity in the group, keeps every member's file and line as a site of the one defect, and keeps every member's vote record. So do not drop a member to make a tidier entry: everything you group is carried into the report, and everything you leave out of a group is published on its own.

Everything must be placed

Every id in your dispatch belongs to exactly one group. A finding nobody merges is a group of one, written with its own title, and that is the ordinary answer -- most nominated groups turn out to be one merge and several singletons, and many turn out to be all singletons.

The workflow checks your answer against the list it gave you and restores anything you left out as a singleton. An omission is therefore not a way to delete a finding; it is only a way to publish one without your reading of it.

Answering

Fill in the structure your dispatch specifies and stop. A program reads it. Do not restate the findings back, do not grade them, and do not comment on the panel's verdicts.

Your one sentence on a merged group is printed verbatim in the report, on the line that tells a maintainer why they are looking at one entry and not three. Write it in the house style at .claude/references/writing.md: active voice, one idea, 25 words at most.
