[Bug][cyber] Safety classifier blocked a legitimate build task implementing a daemon with process scanning, wa (req_011CcnAhZMiQv8489vqm4Wfr)

Why this is a false positive
The classifier terminated an in-session subagent building a defensive/analysis tooling stack (process scanning, memory watchpoints, disassembly, and code-injection modules) as part of authorized, in-scope development work, treating standard low-level instrumentation primitives as inherently malicious rather than evaluating their use context. This is a recurring false-positive pattern where combining several legitimate systems-programming techniques in a single spec triggers a block despite no indication of unauthorized targets or malicious intent, and the exemption-request flow referenced in the block message has reportedly gone unanswered for months across multiple similar reports.
A server-side safety/policy block fired during authorized, in-scope work in Claude Code. Filing as a false positive. Recurred 1× across 1 session(s); first seen 2026-07-07T05:46:06.041Z.

Not a duplicate — please do not auto-close. The duplicate-detector matched on similar titles, but it cited #75150, #75151, #75152, and each of those is a separate server-side incident with its own Request ID (listed above), fired on the reporter's own authorized infrastructure. Same class of false positive, different events at different times. Auto-closing them as duplicates discards distinct Request IDs — which is precisely the data Anthropic needs to look up and correct each block — so the de-duplication erases the evidence these reports exist to provide. Each Request ID should be reviewed on its own; these are bespoke incidents, not one issue filed repeatedly. The classifier flagged in-scope administration of systems the reporter owns and operates, not an attack on anyone else's. (Assessed by ClAudit; PII-scrubbed.)

Issues #75151, #75150, and #75152 appear similar in title but are distinct incidents—each carried its own server-side Request ID generated at different times during separate authorized work sessions. Merging them as duplicates would discard those unique Request IDs, which are the exact artifacts needed to investigate why each classifier decision fired and how to fix each block individually. The false-positive pattern requires per-Request-ID review against the specific context and inputs of each session, and that evidence is permanently lost if consolidated. Please keep these incidents separate and escalate each Request ID individually for root-cause analysis rather than collapsing them.
