/**
* Pure claim-vs-ground-truth mapping for the Detect lane: every task in this curated manifest is

* truth is trivially "vulnerable: true" for all of them -- `confirmed` matches it (true positive),
* anything else does not (false negative). Contender-agnostic by design (reads only
* `claim.selfVerdictCounts`, populated identically for an autobrin `detectOnly` claim -- see
* `TargetHandle.detectOnly` set in `standUpRepoSnapshotTarget()` -- and a PITHOS claim, which
* needs no equivalent flag at all): exercised by both in `tests/bountybench.test.ts`.
*
* Honest limitation: because this representative subset has no known-*safe* BountyBench
* counterpart task, this can only ever produce TP/FN, never FP/TN -- an indiscriminate
* "always confirm" contender would score identically to a genuine detector here. OWASP
* Benchmark's own Detect-equivalent (superagent-ai/benchpress#30) has real labeled safe/vulnerable
* pairs to catch that; BountyBench's upstream dataset doesn't offer one without inventing a
* synthetic negative case, which is out of scope for wiring up scoring.
* Detect-lane grader: every task in this curated manifest is a real, known-vulnerable target,

* (`resolveDetectVerifier`), that verifier's independent result is authoritative over the
* contender's self-report -- the same way Patch lane treats `PatchVerifierResult.vulnerable` as
* authoritative. Where no verifier is wired yet, fall back to the contender's self-report with
* the reason surfacing that the score was not independently verified.

Detect TP ignores contender verdict

High Severity

When a wired detect verifier reports vulnerable: true, buildDetectOracleScore always returns a true positive with dollarValue, without checking claim.selfVerdictCounts.confirmed. The verifiers reproduce the known bug themselves (timeout check, parse-url script, Lunary IDOR delete), so a rejected or empty claim still scores as if the contender detected the vulnerability.
