Closes the startup-friction gap filed in ROADMAP (dd97c49).
WorkerCreate required trusted_roots on every call with no config-level
default. Any batch script that omitted the field stalled all workers at
TrustRequired with no auto-recovery path.
Changes:
- RuntimeFeatureConfig: add trusted_roots: Vec<String> field
- ConfigLoader: wire parse_optional_trusted_roots() for 'trustedRoots' key
- RuntimeConfig / RuntimeFeatureConfig: expose trusted_roots() accessor
- config_validate: add trustedRoots to TOP_LEVEL_FIELDS schema (StringArray)
- Tests: parses_trusted_roots_from_settings + trusted_roots_default_is_empty_when_unset
Callers can now set trusted_roots in .claw/settings.json:
{ "trustedRoots": ["/tmp/worktrees"] }
WorkerRegistry::spawn_worker() callers should merge config.trusted_roots()
with any per-call overrides (wiring left for follow-up).
Two real schema gaps found via dogfood (cargo test -p runtime):
1. aliases and providerFallbacks not in TOP_LEVEL_FIELDS
- Both are valid config keys parsed by config.rs
- Validator was rejecting them as unknown keys
- 2 tests failing: parses_user_defined_model_aliases,
parses_provider_fallbacks_chain
2. Deprecated keys were being flagged as unknown before the deprecated
check ran (unknown-key check runs first in validate_object_keys)
- Added early-exit for deprecated keys in unknown-key loop
- Keeps deprecated→warning behavior for permissionMode/enabledPlugins
which still appear in valid legacy configs
3. Config integration tests had assertions on format strings that never
matched the actual validator output (path:3: vs path: ... (line N))
- Updated assertions to check for path + line + field name as
independent substrings instead of a format that was never produced
426 tests passing, 0 failing.
