Boot smoke (#2275) exercises executor.execute() against stub deps
and never hits the real provider, so missing auth env is not a real
blocker. Without this bypass, every adapter that introduces a new
auth env var must be mirrored into molecule-ci's fake-env list — a
maintenance treadmill that just bit hermes-template:
- 2026-05-03 09:47 UTC: hermes publish-image smoke fails on
HERMES_API_KEY preflight (workflow injects CLAUDE_CODE_OAUTH_TOKEN,
ANTHROPIC_API_KEY, GEMINI_API_KEY, OPENAI_API_KEY but not
HERMES_API_KEY or OPENROUTER_API_KEY). Failed for two cycles
before being noticed.
The bypass demotes Required-env failures to warnings when
MOLECULE_SMOKE_MODE is truthy, so the unset env stays visible in
the boot log without blocking. Production paths are unchanged
(env unset → fail).

Two self-review nits on the prior commit:
- Add test_per_model_required_env_null_treated_as_empty_no_auth — pins
parser tolerance for YAML 'required_env:' (deserializes to None). The
'or []' fallback handles it, but the behavior wasn't asserted, and a
template author who writes 'required_env:' with no value (common YAML
mistake) needs the no-auth path, not a confusing TypeError.
- Drop the MINIMAX_API_KEY delenv from the explicit-empty test — there's
no MINIMAX in any required_env list of that scenario, so the cleanup
was dead noise.
78/78 tests pass.

Two follow-ups from the independent review of #2538.
preflight.py
============
Today: `if per_model_env: required_env = list(per_model_env)` falls
through on `[]`, so a template entry that says "this model needs no
auth" (`required_env: []` — Ollama, llamafile, self-hosted OpenAI-
compat, anything where the SDK doesn't surface a key) is silently
overridden by the top-level fallback list. The template author cannot
express a zero-auth model without lying about its env requirements.
Fix: key off `"required_env" in entry` (key presence, not truthiness).
Missing key still falls back to top-level — that path is unchanged
and preserves "many templates list name/description per model without
enumerating env vars when auth is identical across the family". Empty
list now wins outright. Comment updated to call out the distinction.
test_preflight.py
=================
Renamed `test_per_model_match_with_no_required_env_falls_back_to_top_level`
to `…_no_required_env_KEY_…` and tightened its docstring to reflect
that it's the missing-KEY case only. Added new
`test_per_model_explicit_empty_required_env_means_no_auth` to pin the
new explicit-empty semantic.
test_config.py
==============
New `test_runtime_config_model_env_wins_over_explicit_yaml`. Pins the
intentional precedence inversion shipped in #2538 with both
MODEL_PROVIDER and runtime_config.model in YAML set — MODEL_PROVIDER
wins. Without this pin a future refactor could quietly restore the
old YAML-wins order and re-introduce Bug B.
77/77 targeted tests pass locally.
Closes#250 (review follow-up). Builds on merged #2538.

Two surgical edits to the molecule-runtime workspace package that fix
Bug B (canvas-picked model silently dropped for templated workspaces)
and Bug D (preflight rejects valid auth for non-default models),
universally for every adapter.
Bug B — canvas-picked model dropped (config.py)
================================================
Before: load_config resolved runtime_config.model as
runtime_raw.get("model") or model
which means a template's `runtime_config.model: sonnet` always wins
over the canvas-picked MODEL_PROVIDER env var. Surfaced 2026-05-02
during MiniMax E2E — picking MiniMax-M2.7 in canvas, server plumbed
MODEL_PROVIDER=MiniMax-M2.7 correctly, but the workspace booted with
sonnet because the template's verbatim config.yaml won.
After:
os.environ.get("MODEL_PROVIDER") or runtime_raw.get("model") or model
Centralising in load_config means EVERY adapter (claude-code, hermes,
codex, langgraph, future ones) gets canvas-picked-model passthrough
for free — no per-adapter env-reading code required.
Bug D — preflight per-model required_env (preflight.py)
========================================================
Before: preflight read the top-level required_env list, which
declares the auth needed by the *default* model. A template like
claude-code-default declares CLAUDE_CODE_OAUTH_TOKEN at the top
level. When a user picked MiniMax instead and only set
MINIMAX_API_KEY, preflight rejected the workspace with
"missing CLAUDE_CODE_OAUTH_TOKEN" and the workspace crash-looped
despite the user having satisfied the picked model's actual auth.
After: when runtime_config.models[] declares per-entry required_env,
preflight matches the picked model id (case-insensitive) and uses
that entry's required_env outright instead of the top-level list.
REPLACE semantics, not union — different models have *different*
auth paths (OAuth vs API key vs third-party provider key); unioning
would re-introduce the very crash-loop this fix closes.
Surface enabling both fixes (config.py)
========================================
RuntimeConfig now carries `models: list[dict]` so the canvas Model
dropdown source flows through to preflight without forcing the
parser schema to grow. Malformed entries are silently dropped to
match the rest of the lenient parser.
Tests
=====
- workspace/tests/test_preflight.py: 9 new tests covering the
per-model lookup (case-insensitive, REPLACE not union, fallback
to top-level when no models[] or no match, multi-entry, malformed
entries dropped, etc.)
- workspace/tests/test_config.py: existing 48 pass; field
initialisation already covered by parser tests.
- All 75 targeted tests pass locally; CI runs the full suite
including coverage gate.
Closes part of #246. Sibling PR opens against
molecule-ai-workspace-template-claude-code for per-template
defensive fixes + boot debug logging.

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.
