Adds a new pScheduler tool plugin that provides STAMP (RFC 8762) and TWAMP protocol support using Nokia's twampy CLI client. Supports latency and rtt test types with fragmentation control (DF bit), DSCP/TOS marking, configurable packet count/interval, and source address binding. Includes unit tests for all plugin components (can-run, duration, enumerate, merged-results, participant-data) and full RPM/DEB packaging.

- Fix per-packet regex to match twampy's actual output format: "Reply from <IP> [rseq=N sseq=N rtt=Xms outbound=Xms inbound=Xms]" - Fix summary regex to parse tabular format (Outbound/Inbound/Roundtrip) - Add --verbose flag (required for per-packet output from twampy) - Combine stdout+stderr parsing (per-packet goes to stderr via logging) - Enforce RFC 8762 minimum padding (30 bytes = 44 byte sender packet) - Map outbound/inbound correctly to T2-T1 / T4-T3 timestamps - Add clock synchronization note for one-way delay measurements - Clarify STAMP/TWAMP-Light compatibility in description - Track both sender and reflector sequence numbers Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Plugin Structure
Follows the standard
pscheduler-tool-*plugin layout:can-run— validates test type (latency/rtt), protocol (stamp/twamp), and twampy availabilityrun— builds and executestwampy sendercommand, parses per-packet output into histograms/statisticsduration— calculates expected test durationenumerate— declares tool metadata (name, supported tests, preference)merged-results— combines multi-participant results with flip supportparticipant-data— returns participant-specific metadataSupported Features
Key Differences from twping
twampyPython CLI instead of C-basedtwping--do-not-fragment)Test Plan
can-run— validates accepted/rejected test types, protocols, fragment optionduration— verifies duration calculation with default and custom parametersenumerate— validates JSON schema, tool name, supported tests, preferencemerged-results— single result, two results, flip optionparticipant-data— returns empty object for single-participant mode🤖 Generated with Claude Code
