- shell_hooks is the shared home: _ToolMatcherMixin (matcher compile + matches_tool),
_payload_fields, _forget_home_registrations, _home_key, _utc_now_iso now serve
outbound_webhooks too (copies deleted; every log string byte-identical).
- shell_hooks: response parsing is a per-event dispatch table; _spawn diagnostic
dict + _evaluate_result shared by the live callback and run_once;
_locked_update_approvals POSIX/non-POSIX bodies merged via ExitStack.
- tool_guardrails: ToolCallGuardrailConfig thresholds from a _THRESHOLD_SOURCES
table (nested-wins-over-flat preserved); _int_at_least replaces
_positive_int/_non_negative_int; observe_identical_call (0 refs) folded into
observe_call; _halt helper for hard-stop decisions.
- tool_dispatch_helpers: _plan_tool_batch_segments split into _batch_admission +
close/extend helpers with the post-hoc normalization merged in.
- Comment/docstring compaction keeping every stated rule.
