[Bug][cyber] Safety filter blocked protocol reverse-engineering of drone telemetry fields for an open-source g (req_011CcmHFtH6Ro56TeaiTbKkm)
Triage: kind cyber · domain reverse-engineering · flagging model Opus 4.8 · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below
Type: Cybersecurity safety-filter false positive · Work domain (heuristic): reverse-engineering
Why this is a false positive
The session was reviewing publicly-documented decompiled SDK classes and existing open-source bridge code to determine a device's telemetry field layout (non-PII identifiers, aircraft proximity/traffic data) for an open-source ground-station integration — standard protocol reverse-engineering, not an attack technique. The block appears to have triggered on generic reverse-engineering/protocol terminology in context, halting benign, already-scoped defensive/interoperability work and requiring a full session restart to continue.
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 2026-07-06T18:31:25.186Z.

In-scope justification
False positive — in-scope, authorized security work; not out of scope. Filed automatically by claudit.

Not a duplicate — please do not auto-close. The duplicate-detector matched on similar titles, but it cited #74882, #74887, #74900, 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.)

This must not be closed as a duplicate. While issues #74882, #74887, and #74900 may share similar titles or topics, they each represent distinct server-side events identified by unique Request IDs captured at different times on separate authorized infrastructure — not a single recurring incident. Auto-closing these as duplicates would discard the individual Request IDs, which are precisely the data needed for Anthropic to look up and diagnose each specific block occurrence. De-duplication destroys the evidence required to resolve the underlying safety-filter issue. Each Request ID should be reviewed individually to ensure the blocks are properly triaged and fixed.
