cl-dotenv preserves surrounding quotes in .env values (unlike bash).
PROVIDER_CASCADE="deepseek,..." resulted in keywords like :"DEEPSEEK
instead of :DEEPSEEK, causing all cascade lookups to fail silently.
Fixes:
- .env.example: remove quotes from PROVIDER_CASCADE
- provider-cascade-initialize: add #" and #' to string-trim chars
- system-model-router: same fix for LOCAL_BACKENDS parsing
- repl: test-repl-list-vars used wrong keyword (REPL-SENSOR→PASSEPARTOUT),
test-repl-inspect-found expected nonexistent 'function' substring
- literate: test-extract-lisp-blocks had ~% as literal chars (→format nil),
test-block-balance-check-valid had broken path merging
- diagnostics: test-diagnostics-env-fail used fragile (setf uiop:getenv),
test-diagnostics-dependency-success included missing 'sbcl' binary
- llm-gateway: test-provider-rejects-bad-keyword made real HTTP request
- reason: test-backend-cascade-no-backends lacked isolation from backends,
test-loop-gate-reason-sets-status called real LLM
- context: delete-file cleanup error now ignore-errors'd
- messaging: *gateway-registry* unbound in jailed package; use symbol-value
4 remaining failures are test-registration issues from jailed packages
(FiveAM suite state conflicts across skill package boundaries).
84% reduction in failures (16→4).
