OpenRouter selected but OPENROUTER_API_KEY is not configured

Error message

OpenRouter selected but OPENROUTER_API_KEY is not configured.

What it means

RuntimeError raised in resolve_runtime when provider is 'openrouter' but OPENROUTER_API_KEY is absent from config. Unlike the big-three providers the key is read inline from the config dict at this branch, so it must be present in whatever env/.env layer populates config.

Solutions

1. Add OPENROUTER_API_KEY to the loaded env layer (.env file or process env)
2. Verify the harness/gateway invoking the engine passes the variable through
3. Test with a trivial config load before the full run to confirm the key resolves

Example fix

# before
LAST30DAYS_REASONING_PROVIDER=openrouter
# no OPENROUTER_API_KEY

# after
LAST30DAYS_REASONING_PROVIDER=openrouter
OPENROUTER_API_KEY=sk-or-v1-...

When it happens

Trigger: LAST30DAYS_REASONING_PROVIDER=openrouter with OPENROUTER_API_KEY not set in the environment or ~/.config/last30days/.env; or set in the shell but the engine was launched from another context (cron, harness gateway) without it.

Common situations: OpenRouter key obtained from openrouter.ai/keys but never added to config; per-harness env inheritance gaps (gateway processes stripping env); typo'd variable name.
