Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to This test-only change adds targeted regression coverage, but the git refusal assertion is narrower than the documented secure behavior and could make CI fail on an equally safe refusal response; confirm the message contract or broaden the assertion before merging.

…orkspace denylist, and the null-classed driver refusal Three of the four gaps found auditing tinyhumansai#5672, tinyhumansai#5807, tinyhumansai#5825 and tinyhumansai#5847. Each test drives the surface an agent actually calls, and each was checked by reverting its fix and confirming the test fails naming its own assertion. - tinyhumansai#5672 — a repository config naming a command does not get to run it, asserted through `GitOperationsTool::execute` rather than the private helper the unit suite uses. The assertion is a marker file the planted `core.fsmonitor` hook would create: an error alone would not distinguish "refused" from "refused after spawning git". Revert the guard and the hook runs *and* the tool returns a clean status payload, so the agent is told everything is fine while attacker-controlled code executes. A second test pins the other direction — an ordinary `git init` + identity still works — so a future tightening of `ALLOWED_REPO_CONFIG` that breaks real repositories fails here rather than in the field. - tinyhumansai#5847 — the one behaviour deliberately retained when TinyPlace was deleted. Agent file tools cannot read or write `tinyplace/` inside the workspace at full autonomy, and the file is byte-identical afterwards, so a refusal that only prints an error would not pass. `redirect_links` and `codegraph` are asserted alongside it: all three are retained-after-removal entries with the same rationale, and a test naming only `tinyplace` would miss a regression that took all three. A control read of an ordinary workspace file keeps the test from passing because everything is blocked. - tinyhumansai#5807 — importing into a driver deliberately given `class = "null"` names that driver and its class, and does not blame a build with no memory module. Driven through `migration_helpers::rpc::migrate_openclaw`, the function the `config.openclaw` RPC handler calls, with an explicit `Config` so the assertion does not depend on process-global state shared with the rest of the merged test binary. tinyhumansai#5825 is deliberately not covered, and the reason is recorded rather than papered over: no provider reachable from an integration target exposes `as_scoring()`, so the only test that could be written there asserts the fail-open fallback — which is the pre-change behaviour and therefore passes with the fix reverted. A vacuous test that satisfies the string-match gate would be worse than the gap. One bug found while writing these: tinyhumansai#5672's refusal message never reaches the agent. Every operation is preceded by a `rev-parse --is-inside-work-tree` probe that runs through the same guarded function, so a refused probe collapses to "Not in a git repository" for a directory that plainly is one. The security property is unaffected; the diagnostic is lost. The test asserts the property that holds and carries a comment saying why it does not assert the message.
Review follow-ups on the tests this branch adds. The write-refusal assertion now also checks the refusal does not echo the protected file back. The read path already rejected the seeded token in its output; the write path checked only the error flag and the on-disk bytes, so a refusal that quoted the existing file would have satisfied both and still leaked it. The null-classed-driver assertion now requires the quoted `"null"` class rather than a bare `null` substring — the driver id in the fixture is `mynull`, which contains `null`, so the looser check would have been satisfied by the id alone and proved nothing about the class the refusal names. The product fix this commit originally carried — dropping `diff.external=` from NEUTRALISED_CONFIG — is gone: `30ba798fe` fixed the same bug on main and did it better, suppressing the external diff with `git diff --no-ext-diff` rather than relying on the allowlist alone, and `34fe8e90d` extended that to `--no-textconv`. Main's version is a strict superset, so the rebase keeps main's and drops mine.

Summary
-c diff.external=broke everydiffthrough the tool. See the commit and the note at the end.Problem
The repo's domain e2e gate is a string match, so a name appearing in a comment or an unrelated fixture satisfies it. All four PRs passed that gate while nothing asserted their behaviour:
tools_network_channels_raw_coverage_e2e.rsmatchedgit_operationsbut asserted only the sanitizer, policy-block and log round-trip; andtool-shell-git-flow.spec.tsmatched it inside a comment saying it does not drive the tool.is_workspace_internal_pathhit was inside an assertion message string in a non-_e2efile.embeddings_provider: Noneand asserts nothing about it.openclawhits were an unrelated channel-proxy fixture.Solution
git_tool_refuses_a_workspace_repo_config_that_names_a_command— plants acore.fsmonitorhook that touches a marker, proven to run before it is planted, then callsGitOperationsTool::execute. The marker is asserted first, before anything about the result: an error alone cannot distinguish "refused" from "refused after spawning git", and asserting the error first would abort before reaching the question that matters.git_tool_still_runs_under_an_ordinary_repository_config— the other direction. An allowlist that refusedgit init+ an identity would make the tool useless, so this fails ifALLOWED_REPO_CONFIGis ever tightened past real repositories.file_tools_cannot_reach_retained_legacy_state_in_the_workspace— full autonomy, workspace-relative paths (what an agent actually sends;workspace_onlyrejects every absolute path atpath_checks.rs:88for reasons unrelated to the denylist). Asserts the read is refused, the secret does not appear in the output, the write is refused, and the file is byte-identical afterwards — a refusal printed after the write would not pass. Coversredirect_linksandcodegraphtoo: same rationale, and a regression would take all three. A control read of an ordinary workspace file keeps it from passing because everything is blocked.openclaw_import_names_a_null_classed_driver_rather_than_the_build— drivesmigration_helpers::rpc::migrate_openclaw, the function theconfig.openclawRPC handler calls, with an explicitConfigso it does not depend on process-global state shared across the merged test binary.Revert-check results

4 passed; 0 failed).Why #5825 is not covered
To assert the changed behaviour an e2e needs a bound provider whose
as_scoring()isSome. None is reachable from an integration target: the default impl returnsNone,guard::test_supportispub(crate)(guard/mod.rs:111), every injection seam ispub(crate)(binding.rs:453/566/595), and the module route requires#[ignore]+ its own process by the repo's own convention (tool_stats_tests.rs:48) — impossible inside the mergedraw_coverage_allbinary.The test that is writable asserts the fail-open fallback ("scoring absent → model walk"), which is exactly the pre-#5825 behaviour and therefore passes with the fix reverted. It would satisfy the string-match gate and prove nothing, so I did not write it. Full analysis and what would unblock it:

Proven with plain git (git -c diff.external= diff→ `error: cannot run : No such file or directory` / `fatal: external diff died`). Fixed in this PR; the entry was redundant anyway — `diff.external` is not on `ALLOWED_REPO_CONFIG` and `GIT_EXTERNAL_DIFF` is already cleared from the environment.
