07c338f55d fix(safety): escape tool output XML content and remove misleading sanitized attr (#1067)
* fix(safety): escape tool output XML content and remove misleading sanitized attr

The `sanitized="true/false"` attribute on `<tool_output>` misled LLMs into
treating unfiltered content as pre-sanitized. Remove it and add
`escape_xml_content()` to escape `<`, `>`, `&` in tool output body text,
preventing injected XML from breaking the structural boundary.

* fix(safety): replace contains assertions with exact assert_eq checks

Address Gemini review feedback on PR #1067: replace weak `contains`
assertions with precise `assert_eq!` comparisons in three safety tests
(wrap_for_llm escaping, XML boundary escape, escape_xml_content).

* fix: replace full XML escaping with targeted </tool_output escape to preserve JSON content

The previous approach escaped all XML metacharacters (<, >, &) in tool
output, which corrupted JSON content visible to the LLM. This was the
same issue that caused PR #598 to be reverted.

Now only the closing </tool_output sequence is neutralized (via a
zero-width space insertion), matching the pattern already used by
escape_skill_content(). All other content including JSON with angle
brackets and ampersands passes through unchanged.

Also:
- Remove unused _sanitized parameter from wrap_for_llm()
- Add unwrap_tool_output() with reverse escaping for round-trip fidelity
- Add round-trip tests verifying JSON content survives wrap/unwrap
- Update trace_llm test helper to use the new unwrap_tool_output()

* fix: remove unwrap/expect from escape_tool_output_close to pass CI

Replace regex-based escaping with simple string search to avoid
.unwrap()/.expect() in production code (enforced by CI).

* fix: remove stale 3rd arg from wrap_for_llm bench call

Co-Authored-By: Claude Opus 4.6 <[email protected]>

* fix: address PR review - remove stale 3-arg call, add JSON round-trip test

Fix the test_wrap_for_llm_escapes_attr_chars test that still passed a
third `_sanitized` argument to wrap_for_llm (removed in earlier commit).

Add explicit JSON round-trip test with XML metacharacters
({"query": "a < b & c > d"}) confirming they survive wrap/unwrap intact,
as requested in PR #1067 review.

* fix: remove stale sanitized= references from test fixtures, fix clippy warning

Update web/util.rs test fixtures to use the new tool_output format
without the removed sanitized="..." attribute. Remove redundant
#![cfg(test)] in codex_test_helpers.rs (already gated in mod.rs).

* test: add round-trip JSON parsing regression gate for PR #598

Adds a test that verifies JSON content with XML metacharacters (<, >, &)
survives the full wrap_for_llm -> unwrap_tool_output -> serde_json::from_str
pipeline intact. This guards against the exact corruption scenario that
motivated reverting full XML escaping in PR #598.

* fix(safety): harden wrap_external_content against boundary injection

Address reviewer feedback: apply the same targeted escaping strategy
to wrap_external_content() that was applied to wrap_for_llm(). The
closing delimiter "--- END EXTERNAL CONTENT ---" is now neutralized
in content bodies using a zero-width space, preventing an attacker
from injecting a fake closing delimiter to break out of the wrapper.

15ab156d62 feat: add Criterion benchmarks for safety layer hot paths (#836)
* feat: add Criterion benchmarks for safety layer hot paths

Add benchmark suite using Criterion.rs for performance-critical paths:

- benches/safety_check.rs: Sanitizer (clean/adversarial), Validator
  (normal/long/tool params), LeakDetector (clean/secrets/HTTP scan)
- benches/tool_dispatch.rs: JSON parsing, schema validation patterns,
  tool output serialization

CI compiles benchmarks on every PR to prevent regressions.
Run locally with: cargo bench

Co-Authored-By: Claude Opus 4.6 <[email protected]>

* fix: add bench-compile to CI roll-up job

Include bench-compile in the run-tests roll-up job's needs array
so benchmark compilation failures block PRs.

* fix: add black_box to benchmarks, use real SafetyLayer pipeline

- Wrap all benchmark inputs in criterion::black_box to prevent
  compiler optimization from skewing results
- Replace generic JSON benchmarks in tool_dispatch.rs with actual
  SafetyLayer pipeline benchmarks (sanitize_tool_output, wrap_for_llm,
  scan_inbound_for_secrets)
- Keep JSON parsing benchmarks for tool parameter overhead measurement

* fix: apply cargo fmt to benchmark files

Co-Authored-By: Claude Opus 4.6 <[email protected]>

* fix: copy benches/ in Dockerfile to fix manifest parse error

Cargo.toml references [[bench]] targets that must exist for manifest
parsing to succeed. Add COPY benches/ to the Docker build stage.

* chore: re-trigger CI after adding skip-regression-check label

Co-Authored-By: Claude Opus 4.6 <[email protected]>

* fix: address PR review comments on criterion benchmarks

- Move header string allocations outside b.iter() closure in
  http_request_scan to avoid measuring allocation overhead
- Add .unwrap() to serde_json::from_str results in JSON parsing
  benchmarks to catch invalid JSON instead of silently benchmarking
  error construction
- Add comment explaining why benches/ COPY is needed in Dockerfile
  ([[bench]] entries require source files for cargo manifest parsing)

* fix(bench): build secret-like strings at runtime to avoid CI secret scanners

Construct AWS key and GitHub token patterns via format!() concatenation
so the literal strings don't appear in source and trigger push protection
or secret scanning in CI pipelines. The resulting strings still match
LeakDetector patterns for valid benchmarking.

* fix: rename tool_dispatch bench, drop async_tokio, replace JSON benchmarks

1. Rename `tool_dispatch.rs` → `safety_pipeline.rs` to match actual
   content (SafetyLayer pipeline benchmarks).
2. Drop unused `async_tokio` feature from criterion dependency.
3. Replace serde_json::from_str benchmarks (third-party only) with
   Validator::validate_tool_params exercising IronClaw's recursive
   validation on simple, complex, and deeply nested JSON inputs.
4. Add `--all-features` to CI bench-compile to match clippy/test
   convention and verify both DB backends.

Addresses zmanian's review feedback on PR #836.
