One registry test may not detect propagation of the wrong handle, so it is mergeable with explicit owner awareness and follow-up to strengthen that assertion. Suggested reviewers: Poem

Assert the registry handle value, not only its presence.
is_some() proves only that the erased extension contains a PackRegistryHandle. If LoadSkillTool::new stores a different or default handle, this test still passes while toolpacks::ops reads the wrong registry. Use a non-default observable registry entry or a comparable handle, then assert that the recovered value matches the supplied handle.

Flagging something I found after opening this, because it changes how the Playwright half of this PR should be reviewed. The spec added here (
Net effect: a Playwright spec merges to I could not close this locally either — the lane's build ( So please treat that one file as reviewed-by-reading, not verified. What is verified is the discriminator it depends on: with The three Rust suites are unaffected — they run in Happy to drop the spec from this PR if you would rather not carry an unexecuted file; I left it in because the gap is in the lane, not the test.

CI note: the one red test is pre-existing, exposed by this PR rather than caused by it. I have deliberately not touched it.
Why it runs here at all. Root cause. There is already an open PR that fixes exactly this: #5672. It sets I could have got this PR green with an Second-order point worth someone's attention: because of that scoping rule, a red test can sit in the aggregate suite indefinitely — most PRs never select it, so a green run says nothing about the other ~75 suites. |
…ased tool extensions and theme import Four recently merged PRs changed behaviour that no e2e test drives. Each test below was mutation-checked: with the fix reverted it fails naming its own assertion. - tinyhumansai#5779 `flush_source_tree`'s re-entrancy latch. A failing flush used to latch its scope out for the life of the process, so the natural retry answered "already running" forever. Reverted, the retry comes back `Ok(seals_fired: 0)` with that log line and the test fails. - tinyhumansai#5854 `as_bus_scope`, the host->bus join the retrieval handlers were rewired onto. `None` means unrestricted and must stay `None`; an empty `SourceScope` denies every source-attributed item, so collapsing the two inverts the policy and silently blanks recall. Nothing asserted it — every occurrence in the tree was a call site or a comment. - tinyhumansai#5841 the erased `dyn Any` host extensions. Both the e2e and unit lanes only asserted `is_none()`, which is also the silent-downcast failure mode, so the failure and the only tested state were the same value. Adds the `Some` side, plus the MCP error-flag orientation the PR itself flagged as easy to get backwards. - tinyhumansai#5946 theme import validation, in the Playwright lane. `typeof null` and `typeof []` are both `'object'`, so malformed pastes were stored; a non-string token value then threw in `channelsToCss`, crashing the panel on an already-stored theme. The empty-`colors` case is asserted as ACCEPTED on purpose: CLASSIC_LIGHT and CLASSIC_DARK both carry `colors: {}`, so rejecting it would break the panel's own export -> import round trip.

…ternal override
`hardened_git` puts `-c diff.external=` on every git invocation to
neutralise a repository that names an external diff program. An empty
`diff.external` does not mean "no external diff" to git — it means "run
the empty program" — so every `git diff` through this tool died with:
error: cannot run : No such file or directory
That is unconditional: hostile repository or not, the tool's `diff`
operation could not produce a patch.
`--no-ext-diff` is the mechanism that actually expresses the intent. It
still denies a repository its external diff program, and git produces the
patch itself. Verified against a repo carrying
`diff.external = /bin/echo PWNED`: unguarded git runs the program;
`-c diff.external=` dies; `--no-ext-diff` returns a real patch and never
runs it. No guard is removed — the `-c` override stays.
Caught by the existing `git_operations_cover_read_write_markdown_and_safety_rejections`,
which this branch made the coverage job select: a change under
tests/raw_coverage/ scopes that job to the whole raw_coverage_all target
(scripts/ci/rust-coverage-changed.sh:337-345), so most PRs never run it.

Summary
raw_coveragelane and one Playwright spec. 482 lines, all test code — no production file is touched.## Impact.Problem
An audit of the last seven days' merges found that the two PRs which did touch an
*_e2e.rsfile did so in ways that satisfy the domain gate — which is a string match — while asserting nothing about the change: #5932 bumped a schema count 35→37, and #5841 rewrote an existingis_none()assertion into the new call form. The gaps left behind:flush_source_tree's re-entrancy latch. Releasing it only on success meant a failing flush latched that scope out for the life of the process — the natural retry answered "already running" forever.as_bus_scope, the host→bus join the retrieval handlers were rewired onto. Every occurrence in the tree was a call site or a comment; nothing asserted it.dyn Anyhost extensions. Both lanes asserted onlyis_none()— which is also the silent-downcast failure mode, so the failure and the only tested state were the same value.typeof nullandtypeof []are both'object', so malformed pastes were stored; a non-string token value then threw inchannelsToCss, crashing the panel on an already-stored theme.Solution
tests/raw_coverage/memory_flush_latch_raw_coverage_e2e.rs— drives a failing flush, then retries the same scope, and asserts the retry reaches the driver again. It asserts only that the second call was attempted, not which error it gives, so it does not pin the driver-absent error text.tests/raw_coverage/memory_source_scope_bus_raw_coverage_e2e.rs— pins the asymmetryas_bus_scope's own doc comment names:Noneis unrestricted and must stayNone, while an emptySourceScopedenies every source-attributed item. Collapsing the two inverts the policy and silently blanks recall — both values are well-formed, both type-check, and the handlers report an empty page as a legitimate answer, so an inversion surfaces as "memory forgot everything" with nothing in the logs. A third test asserts a populated allowlist throughSourceScope::allows_source_id, tying the host's rendering to the matching the driver will actually perform.tests/raw_coverage/tools_erased_host_extension_raw_coverage_e2e.rs— asserts theSomeside of both erased readers, and the MCP error-flag orientation the PR itself called out as easy to get backwards. The generated-tool half drives a local fixture because no production tool implementshost_call_extension(see## Related); what is pinned is the seam, and that is stated in the test's doc comment rather than implied.app/test/playwright/specs/settings-theme-import-validation.spec.ts— five malformed shapes refused, and two valid ones still accepted. The signal is the textarea:handleImportclears it only on success and sets the error only on failure, so "error shown and the paste still there" is a state an accepting build cannot produce.The empty-
colorscase is asserted as accepted, deliberately:CLASSIC_LIGHTandCLASSIC_DARKboth carrycolors: {}, so rejecting it would break the panel's own export → import round trip for the two most common themes.Revert-check

a_tool_without_a_host_extension_reads_back_as_nonepassed under both mutations. It is a negative control and cannot fail against a "downcast misses" mutation by construction, so it was vacuous here; the negative case is already asserted attools/traits_tests.rs:52-53andtools_approval_channels_raw_coverage_e2e.rs:1560, so nothing is lost by removing it.Not run locally: the Playwright spec itself. That lane's build (
e2e-web-build.sh) does a fullcargo build --bin openhuman-coreinto a second target directory, which the current fleet memory/disk throttle rules out. What was verified locally is the discriminator the spec relies on — reverted, the component suite reproduces both the accept-the-malformed-paste behaviour and thechannelsToCsscrash — and its selectors (getByLabelText('Import theme'), theImportbutton, the error string) are the same ones the existing component test already resolves against this component. Flagging it as CI-verified rather than claiming a local revert-check I did not run.Submission Checklist

No runtime, platform, performance, security, migration or compatibility impact — no production file is modified. CI gains three
raw_coveragetests (picked up automatically bybuild.rs's module generation, so no registration needed) and one Playwright spec inapp/test/playwright/specs/, which isplaywright.config.ts'stestDir.mainis currently red on theRust Qualitylayout gate. That is pre-existing and being fixed separately; it is not from this branch, which changes no source file.#5932 is not covered, and I do not think it can be from any current lane.
publish_stage("running", …)(integrations/composio/ops/providers_ops.rs:295-322) sits behind two guards a test cannot satisfy:resolve_toolkit_for_connection(ops/connections.rs:257) makes a liveLIST_CONNECTIONSconnectors call, andbinding.provider().as_sources()must beSome, which needs a bound driver. There is no public seam to install a stand-inMemoryProvider— the same wallmemory_core_threads_raw_coverage_e2e.rs:418-427already documents forreset_tree/flush_now. Writing a test that reached neither guard would have been coverage in name only.Related
## Impact: Publish composio sync stage events so the Sources row can settle #5932.Tool::host_call_extensionhas no production implementor (grep -rn "fn host_call_extension" src/returns one hit, a test fixture), sotraits::generated_runtime_contextreturnsNonefor every shipped tool and the generated-tool policy rules intool_policy.rsare never reached with a real context. This predates refactor: take the tool vocabulary from tinytools #5841 — at9f82937c1^the only implementors were the trait default and the same fixture — so it is not a regression, but it is either dead code or a missing producer, and those have opposite fixes.Summary by CodeRabbit
