Closes task #123 — last piece of #87 cleanup. Pre-fix: workspace/preflight.py:11 hardcoded a tuple of "supported" runtime names (claude-code, codex, ollama, langgraph, etc.). Every new template repo required a code change in molecule-runtime to be recognized — direct violation of the universal-runtime principle (#87) where adapters declare themselves and the runtime stays generic. Post-fix: discovery-based validation via the same ADAPTER_MODULE env var that production load paths already consult (workspace/adapters/__init__.py:get_adapter). Distinguished failure modes so operator messages are concrete: - ADAPTER_MODULE unset → "no adapter installed; set the env var" - ADAPTER_MODULE set but module won't import → import error type + message - module imports but no Adapter class → "convention violation, add `Adapter = YourClass`" - Adapter.name() raises → caught with operator message - Adapter.name() returns non-string → contract violation message - Adapter.name() doesn't match config.runtime → drift WARNING (not fatal; the adapter wins in production, config.yaml is just documentation) The drift case is the one behavioral change worth calling out: the prior static-list path would have hard-failed config.runtime values not in the allowlist. With discovery, an unknown runtime in config.yaml is just a documentation drift — the adapter that's actually installed runs regardless. Operator gets a warning naming both the configured and installed names so they can fix whichever is stale. Tests: - Replaces the obsolete "static list pass/fail" tests with 6 new cases covering each distinguished failure mode, plus a positive test for the adapter-matches-config happy path - Adds an autouse `_default_langgraph_adapter` fixture that pre-installs a fake adapter via sys.modules monkey-patching, so existing tests building default WorkspaceConfig (runtime="langgraph") inherit a valid adapter without each test setting ADAPTER_MODULE - Failure-mode tests opt out of the default fixture via @pytest.mark.no_default_adapter (registered in pytest.ini) - Sentinel pattern (`_UNSET = object()`) for `name_returns` so None is a passable test value (otherwise `is not None` would skip the None branch — exact bug the sentinel avoids) Verification: - 22/22 preflight tests pass (was 16; +6 new failure-path tests) - 1256/1256 workspace pytest pass (was 1251; +5 net) - No production code path other than preflight changed Source: 2026-04-27 #87 cleanup audit after PR #2154 (wedge extraction). This change is independent of the cli_executor.py template moves (task #122) — completes one of the two remaining cleanup items. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# Why 86 not 92: the earlier 97% measurement was without the

# .coveragerc omit list. Once `*/__init__.py`, `*/tests/*`, and
|
|
# `plugins_registry/*` are excluded (the issue's prescribed omit
|
|
# set, more meaningful since those files don't carry behavior),
|
|
# the actual measurement of behavior-bearing code is 91.11% — and
|
|
# 86% sits at the issue's prescribed `current - 5pp` margin.
