tradecraft-duplicate-avoidance

Avoid burning time on bugs that will be closed as duplicates. Load during bug-bounty work when deciding what to report or where to dig, on "will this be a dup", "is this already known", maximizing unique findings. Signals: a mature/popular program, a common vuln on an obvious asset, a recently expanded scope.

# Duplicate avoidance

## When it applies
Bug-bounty payouts go to the *first* valid report. On popular programs the obvious bugs on obvious
assets are already found, so the skill is steering toward findings that are still unclaimed — and
recognising when a bug you have is likely already in the queue.

## Why it works
Duplication is a function of visibility and timing: the more hunters have seen an asset and the
longer it's been in scope, the lower your odds on a surface-level bug. Freshness and novelty move you
to the front of the line, where the same effort actually pays.

## Method
1. **Read the disclosed reports** for the program (and the researcher's public activity) to learn
