fix: remove duplicated cfg(test) attribute and fix import order

Remove redundant #![cfg(test)] inner attribute from codex_test_helpers.rs (already gated by #[cfg(test)] in mod.rs), fixing the clippy duplicated_attributes warning. Also apply cargo fmt import reordering in tools/mod.rs. https://claude.ai/code/session_017ckCCurNiBL8uzE4dJg59K
fix: update test refs from coerce_params_to_schema to prepare_params_for_schema

-### Cloud Code API vs standard API
-
-Models containing `-preview` (with hyphen) or `gemini-3` in the name, as well
-as any `gemini-` model with major version >= 2, route through the Cloud Code
-API (`cloudcode-pa.googleapis.com`) which supports SSE streaming
-and project-scoped access. Other models use the standard Generative Language
-API (`generativelanguage.googleapis.com`).

Zaki ManianandClaude	786df99dc7	fix: address review feedback — UTF-8 safe truncation, saturating_sub, lock poison logging, cleanup Co-Authored-By: Claude Opus 4.6 <[email protected]>	2026-03-21 08:13:26 +00:00
ZakiandClaude	9cffb1d6b7	fix(security): address review feedback -- nesting depth, SSE redaction - Nesting depth: change from .max(1) to .saturating_add(1) so the orchestrator always increments the depth server-side rather than trusting the client-supplied value. This prevents a malicious worker from bypassing the nesting limit by always sending 0. - SSE redaction: redact raw input parameters from worker-reported tool_use events in job_event_handler before broadcasting via SSE. Previously only the PTC path redacted; worker-reported events leaked raw parameters (potentially containing API keys, passwords, PII) to the web UI. - Domain check and Python SDK timeout were already addressed in the current branch. - Add regression tests for both fixes.

ZakiandClaude	6c1d0a4828	fix: remove stale append_schema_hint_if_permissive call after rebase Staging moved schema hint logic to display-time in schema() method, so the construction-time call from PTC is no longer needed.

ZakiandClaude	3ad91338f7	security: address review findings -- domain check, nesting depth, SSE redaction Three security fixes from code review: 1. CRITICAL: Block Container-domain tools from executing on the orchestrator host. The ToolExecutor now checks tool.domain() and rejects Container tools with PtcError::DomainBlocked, preventing sandbox escape / RCE. 2. MEDIUM: Floor client-provided nesting_depth at 1 instead of trusting the worker's value. A malicious worker can no longer send nesting_depth=0 to bypass MAX_NESTING_DEPTH. 3. MEDIUM: Redact tool parameters in SSE JobToolUse events to prevent leaking sensitive data (API keys, passwords) to web UI observers. 4. Python SDK: Always send timeout_secs to server and use server_timeout+5 for client-side HTTP timeout to prevent premature client timeouts. Regression test: test_container_domain_blocked verifies Container-domain tools are rejected. Co-Authored-By: Claude Opus 4.6 <[email protected]>	2026-03-21 08:12:54 +00:00

ZakiandClaude	ac8083bd85	feat(ptc): fix WASM wiring, add ptc_script tool, nesting depth, Docker SDK - Fix WASM tool_invoke production wiring: change tool_executor to a shared Arc<std::sync::RwLock> slot with lazy resolution so WASM tools registered during build_all() can access the executor set afterward - Add nesting_depth field to ToolCallRequest and propagate it through the orchestrator's tool_call_handler into JobContext - Add ptc_script built-in tool: runs Python scripts with ironclaw_tools SDK pre-imported, env-scrubbed subprocess, structured output support - Copy Python SDK into Docker worker image at dist-packages path Co-Authored-By: Claude Opus 4.6 <[email protected]>	2026-03-21 08:12:17 +00:00
ZakiandClaude	42e6650ab8	feat(ptc): programmatic tool calling -- executor, SDK, and E2E tests Add ToolExecutor for standalone tool dispatch used by both the orchestrator HTTP RPC endpoint and the WASM tool_invoke host function. Includes Python SDK for container scripts, WASM test fixture, and comprehensive E2E test coverage across all PTC paths. Implementation: - ToolExecutor with timeout, nesting depth limit, safety sanitization - Orchestrator POST /worker/{job_id}/tools/call endpoint with SSE events - WASM tool_invoke host function with alias resolution - Python SDK (stdlib-only) with call_tool + convenience wrappers Tests (16 new): - 6 orchestrator HTTP RPC tests (auth, echo, not-found, timeout, SSE, no-executor) - 3 executor integration tests (sanitization, invalid params, sequential) - 4 Python SDK tests (env vars, request format, HTTP error, wrappers) - 3 WASM E2E tests (echo via alias, alias not granted, no capability) Refs #407 Co-Authored-By: Claude Opus 4.6 <[email protected]>	2026-03-21 08:11:31 +00:00
