# Phase 08 Plan 02: SSH Execution Phase Verification Summary

## One-liner

Phase 3 SSH execution verification report written with 3-source evidence for EXEC-01..03 (node_exec, node_exec_all, transparent reconnect via asyncssh stale-connection retry).

## What Was Built

`.planning/phases/03-ssh-execution/03-VERIFICATION.md` — retroactive verification report closing the audit gap for EXEC-01 through EXEC-03. Phase 3 was fully implemented and tested but lacked a verification report.

The report provides:
- 3 roadmap success criteria verified with code location + test file + test name evidence
- Requirements coverage table mapping EXEC-01..03 to plans, evidence, and test counts
- Per-plan must-have truth tables for all 3 Phase 3 plans (03-01 through 03-03)
- Human verification section for SC-3 live-VM reconnect path

## Verification Results

- `pytest tests/test_ssh_client.py tests/test_node_exec.py tests/test_node_exec_all.py -q`: **23 passed** (9+6+8)
- `ruff check vmcluster_mcp/exec/`: **All checks passed**

## Decisions Made

| Decision | Rationale |
|----------|-----------|
| SC-3 status: VERIFIED (not human_needed) | asyncssh stale-connection retry at ssh.py:89 is fully tested by test_execute_reconnects_on_stale_connection; live VM test is recommended but non-blocking for milestone audit |
| EXEC-03 cites dual implementation paths | Both SSHConnectionManager.execute() reconnect loop and node_crash invalidate() call satisfy the requirement; documenting both provides full coverage picture |

## Deviations from Plan

None — plan executed exactly as written. All acceptance criteria met:
- `03-VERIFICATION.md` exists with `phase: 03-ssh-execution` frontmatter
- `status:` and `score:` fields present
- EXEC-01, EXEC-02, EXEC-03 all present and marked SATISFIED
- 24 VERIFIED markers present (exceeds minimum of 3 for SC rows)
- `human_verification:` block in frontmatter
- Per-plan sections reference 03-01, 03-02, 03-03 (6 matches)
- `asyncio.gather`, `test_ssh_client`, and `PARTIAL_FAILURE` all cited as evidence
