+# Iteration 037 — Observer Report
+
+| Field | Value |
+|---|---|
+| Date | 2026-03-04 |
+| Task | 0041 — `great mcp test <name>` shows wrong error when no `[mcp]` section |
+| Type | bugfix |
+| Complexity | XS |
+| Result | SHIPPED |
+
+## What Happened
+
+Single-token fix in `src/cli/mcp.rs` line 183: added `&& name.is_none()` to the
+`mcps.is_empty()` early-exit guard. This allows named server lookups to reach the
+existing name-specific error message when the MCP map is empty.
+
+## Agent Performance
+
+| Agent | Model | Retries | Notes |
+|---|---|---|---|
+| Nightingale | Sonnet | 0 | Selected 0041 over 0040 (0040 needs design decision first) |
+| Lovelace | Opus | 0 | Clean spec, line numbers verified |
+| Socrates | Opus | 0 | APPROVED first pass |
+| Humboldt | Sonnet | 0 | Confirmed all file locations and patterns |
+| Da Vinci | — | — | Deming implemented directly (XS fix) |
+| Turing | — | — | Tests run by Deming (4 new, all pass) |
+| Kerckhoffs | Haiku | 0 | PASS — no security concerns |
+| Dijkstra | Haiku | 0 | APPROVED — minimal and correct |
+| Wirth | Haiku | 0 | PASS — binary 8.619 MiB, 335 tests |
+| Nielsen | — | — | Skipped (CLI error message, no UX journey) |
+| Rams | — | — | Skipped (no visual changes) |
+| Hopper | — | — | Deming committed directly |
+| Knuth | — | — | Release notes below |
+
+## Metrics
+
+- **Binary size**: 8.619 MiB (baseline unchanged, -512 bytes)
+- **Tests**: 335 total (231 unit + 103 smoke + 1 hook_state), 0 failures
+- **Clippy**: 0 new warnings
+- **Production code changed**: 1 line
+- **Test code added**: 80 lines (4 integration tests)
+
+## Commits
+
+1. `44e2a2d` — `fix(mcp): show name-specific error when no [mcp] section`
+2. `7415132` — `chore: add architecton loop task artifacts`
+
+## Bottleneck
+
+None. XS task completed cleanly in a single pass. Full team was overkill —
+Deming implemented directly and ran lightweight Haiku agents for gates.
+
+## Configuration Change
+
+None. No process changes warranted for this iteration.
+
+## Release Notes
+
+### Fixed
+- `great mcp test <name>` now shows "MCP server '<name>' not found in great.toml"
+  instead of the generic "No MCP servers declared" warning when no `[mcp]` section
+  exists in the config file.
