Pipeline Plan inline

Plan saved to docs/plans/2026-03-02-add-ping-command.md.

Status: Implementation is already complete. The feature was built in a prior pipeline iteration. Here's the summary:

What Was Verified

Component	Status
scripts/sw-ping.sh	✅ Exists — prints pong, handles --help, --version, unknown flags
scripts/sw-ping-test.sh	✅ Exists — 6 tests, all passing
scripts/sw router	✅ Lines 605-606 dispatch ping correctly
package.json	✅ bash scripts/sw-ping-test.sh registered in test suite
Test results	✅ PASS: 6 / FAIL: 0

Plan Summary

The plan documents the full Socratic analysis:

• Alternatives considered: Inline in router (rejected — untestable, inconsistent) vs. standalone script (chosen — modular, consistent with all 100+ existing commands)
• Risk analysis: 5 risks identified with mitigations (router entry, output format, exit codes, Bash 3.2 compat, test registration) — all mitigated
• Definition of done: 9 criteria — all satisfied
• Task decomposition: 5 tasks with explicit dependencies

The pipeline can proceed directly to the build/test stage since all implementation work is done.
