…settings failure paths Six merged PRs changed behaviour that no e2e test exercised. An audit of the three lanes found the changed symbols present in e2e files for three of them — `run_subagent` in nine, `handoff` in eighteen, both profile panels in a Playwright spec — with none of those tests driving the changed path. The repo's domain e2e gate counts literals, so all three read as covered. Rust: - tinyhumansai#5810 `run_subagent` refuses a dispatch after a cap pause, and when less wall-clock remains than the turn's slowest completed child. Both cases install a real `turn_dispatch_guard` (the gate is a no-op outside a turn scope, so a test that skips it exercises nothing) and assert the provider was never reached — the refusal is meant to cost nothing. Each drives an allowed dispatch through the same guard first, so a gate that refused unconditionally could not pass. - tinyhumansai#5772 `probe_alive` returns a four-variant `ProbeOutcome`; the existing test only asked `.is_alive()`, which is false for all three non-alive variants alike. Pins `Missing` for an entry that was never connected, `TimedOut` for a demonstrably healthy server probed with an unmeetable window, and that the session survives it. Also pins the 8s default probe window that b44b958d restored. - tinyhumansai#5852 `wait_agents` prunes a terminal child, so a second wait misses. The one semantic change in an otherwise-deletion PR; it lived only in prose. - tinyhumansai#5839 the `memory_diff` RPC surface answers unknown-method on the live router, and the memory domain still answers. The existing removal regression reads the registry as a data structure, so a re-registration behind a different namespace would satisfy it. Playwright: - tinyhumansai#5944 a failing profile save, activate and delete each show the backend's reason and not `[object Object]`. Every existing test in that spec is a happy path, which is how the defect shipped and was then pinned as expected. - tinyhumansai#5925 a settings-load failure disables every compression switch; a savings failure leaves them usable. The second is the half the old `Promise.all` broke.
The file was already unformatted on `upstream/main` (verified by running rustfmt against the pristine blob), so `cargo fmt --check` was failing before this branch existed. That matters here rather than being someone else's problem: `rust-core-coverage` is declared `if: … needs['rust-quality'].result == 'success'` (ci-lite.yml:721), so the formatting failure skips the job that would actually run the tests this branch adds. Formatter output only — 10 insertions, 11 deletions, all import ordering and wrapping. Toolchain-pinned rustfmt 1.96.1, matching CI.
…d vacuous Revert-checking found three things, and in two of them the code was right and my test was wrong. - **tinyhumansai#5772 `TimedOut` is not reachable here.** A probe with a `Duration::ZERO` window still returned `Alive { elapsed: 42.708µs }`: `tokio::time::timeout` polls the inner future before it checks the deadline, and `list_tools` on an established stdio connection answers inside that first poll. Producing a real timeout needs a stub that stalls on a named method, which `test-mcp-stub` cannot be asked for. The assertion is dropped rather than contrived; the test keeps the `Missing` half, which is reachable and which the old `bool` API could equally not express. - **tinyhumansai#5810 `observed_samples` is 3, not 2.** The allowed dispatch in the same test completes, and `run_subagent` folds a real child's wall-clock into the estimator on its success path. That the runner measures its own children is the mechanism gate 2 rests on, so counting it is the assertion. - **tinyhumansai#5852's pruning test is removed as vacuous.** Deleting `self.remove(task_id)?` from `DetachedTaskRegistry::wait` did not make it fail — the run rebuilt (1m27s) and still passed, so the entry is pruned by some path other than the one `ops.rs:20-23` documents. It asserted something true without being able to distinguish the documented mechanism from whatever actually does the work, which is not a test that would catch the regression it was written for. Remaining five, each revert-checked: both tinyhumansai#5810 dispatch refusals (gate removed -> both fail), tinyhumansai#5772 `Missing` (Missing -> Broken -> fails naming the assertion), tinyhumansai#5772's 8s window (8s -> 30s -> fails naming the message), and tinyhumansai#5839's `memory_diff` removal.

This PR runs on the merge commit, so it already includes that fix and still fails here — so it is one of the ones still outstanding, not a regression from it. cc @shanu in case this one is not already on your list.

…t an empty config
`NEUTRALISED_CONFIG` carried `diff.external=`, and an empty value does not
disable an external diff — git tries to *execute* the empty string, so every
`diff` operation died before producing a patch:
error: cannot run : No such file or directory
fatal: external diff died, stopping at tracked.txt
Reproduced against git directly rather than inferred:
$ git -c diff.external= diff -- tracked.txt
error: cannot run : No such file or directory # the CI failure verbatim
$ git diff --no-ext-diff -- tracked.txt
+second
`--no-ext-diff` is the real suppression and is strictly stronger: verified
against a repository with `diff.external=/bin/false`, plain `diff` dies and
`--no-ext-diff` still prints the patch. So this hardens the operation where the
old form removed it. `diff.external` is on neither allowlist, so a repository
carrying it is refused before the invocation; this is the second layer, for the
gap between that inspection and the command.
The regression test goes in the **lib** suite deliberately. This broke every
diff on every repository and still reached `main`, because a change to
`git_operations.rs` maps to the `openhuman::tools` libtest filter while the test
that caught it lives in `raw_coverage_all` — a target that filter never selects.
`main`'s own run over this file (8e65c40) therefore did not execute it. A test
here runs whenever this file is touched.
Revert-checked: with `diff.external=` restored and `--no-ext-diff` removed, the
new test fails naming its own assertion and reproducing the exact error above;
restored, 43 pass.
The same entry is still present in `tools/impl/system/workspace_state.rs:235`.
It is latent there — that module runs only `status` and `log --oneline`, neither
of which generates a diff — so it is left alone here and recorded rather than
swept into an unrelated change.

… identity The test failed in CI at the `git commit` fixture step and passed locally. The difference is the container, not the code: `hermetic` closes the global and system config — which is its whole purpose — and CI's git then has no identity to fall back on, so `git commit` refuses with "Author identity unknown". macOS git derives one from the system instead, which is why this could not be reproduced here (verified: the same commit under `GIT_CONFIG_NOSYSTEM=1 GIT_CONFIG_GLOBAL=/dev/null` succeeds locally). Set `user.email` / `user.name` in the repository itself, so the fixture does not depend on whether the host's git can invent an identity. Both keys are on `ALLOWED_REPO_CONFIG`, so this does not trip the repository-config refusal the surrounding tests exercise.

…ading the developer's config
`run_git` in `tools_network_channels_raw_coverage_e2e.rs` spawned git with the
machine's own configuration in scope, and the fixture performs a real `commit`.
A global `commit.gpgsign = true` — which every maintainer who signs commits has
— made that commit try to sign and fail:
gpg: skipped "DEADBEEFDEADBEEF": Input/output error
gpg: signing failed: Input/output error
fatal: failed to write commit object
CI has no global git config, so this was green there and red only on the laptops
of the people most likely to run it. Reported by W2, who lost time to it.
Close the system and global config the way the unit suite's `hermetic()` and the
product's own `suppress_ambient_git_config` do. `GIT_CONFIG_GLOBAL` must name a
readable-but-empty path rather than be unset, or git falls back to `~/.gitconfig`
— the thing being closed. The committer identity is unaffected: the fixture
already sets `user.email` / `user.name` repository-locally, so nothing is
stranded by removing the ambient config.
Revert-checked under a fabricated signing developer's `HOME` (global
`commit.gpgsign = true`, unusable key):
- without the fix: fails at the commit, `gpg: signing failed`
- with the fix: no gpg complaint at all; the commit succeeds
With the fix the test then reaches, and fails on, the `diff.external` defect
fixed earlier in this same PR — which is why the two belong together: neither
alone makes this test pass on a maintainer's machine.
CodeRabbit caught a gap in the `--no-ext-diff` hardening this PR added: `--no-ext-diff` covers `diff.external` and `diff.<driver>.command`, but textconv is a separate mechanism with its own flag. A `.gitattributes` line selecting a driver whose `diff.<driver>.textconv` is set makes git EXECUTE that command to render a binary file as text. Reproduced against a scratch repo before changing anything: with `--no-ext-diff` alone the textconv script ran; with `--no-textconv` added it did not. Scope, stated honestly: this is the same second layer `--no-ext-diff` is, not a live hole. `diff.<driver>.textconv` is not on `ALLOWED_REPO_CONFIG`, which is an allowlist that fails closed, so a repository carrying the key is already refused before the command runs. The flag closes the window between that inspection and the invocation — the same rationale the existing `--no-ext-diff` comment gives for itself. `hardened_git`'s `-c` list cannot do this job: driver names are arbitrary, so there is no finite set of keys to neutralise. It has to be a command flag.

…memory sources Two e2e gaps found in the coverage audit of recently merged PRs. Both paths could break completely today without a single lane going red. tinyhumansai#5808 / tinyhumansai#5801 — `MemorySourceSync::run_source_sync` is a DEFAULTED contract member. `ModuleMemoryProvider` inherited its `Unsupported` body instead of bridging, so "Sync now" answered `unsupported capability: source_sync` on a build whose module could sync fine. A defaulted member that was never bridged is indistinguishable from a bridged one at compile time, which is why it shipped — so this asserts the RUNTIME answer. The discriminator: `binding::build` binds `module_provider` whenever the `modules` feature is on, so this RPC really does reach the bridged member. An unbridged member refuses the capability BEFORE any transport is attempted; a bridged one gets as far as the module. tinyhumansai#5725 — `reset_tree` and `flush_now` were routed through `Maintenance::reset_derived_index` / `flush_pending`. Nothing exercised either afterwards: in the raw-coverage lane both names appear only as string literals fed to `memory::schema::schemas(...)`, and in `worker_c_modules_e2e.rs` they sit in a 68-method loop whose helper passes on an error response. This commit also carries the two review findings raised on the PR, which were both correct and were fixed in a follow-up now folded in by the rebase: - `sources_sync_...` excluded only "unsupported capability" and "source_sync". The other pre-dispatch refusal — `sync_rpc` bailing with "the bound memory driver '<id>' does not serve source sync" (`memory/sources/rpc_part_01.rs:560-564`) — spells it with a SPACE, so it matched neither string and the test passed green while `run_source_sync` was never reached. Now rejected. Proven: forcing `ModuleMemoryProvider::as_source_sync()` to `None` fails the new assertion with the real message; before the change that same revert passed. - `tree_reset_and_flush_...` excluded one string, so a renamed or removed RPC answered `unknown method: <name>`, contained no "does not serve Maintenance", and passed without dispatching. Now rejected, plus a check that the response is a result or an error rather than neither. Neither test asserts success. That would need a live module artifact fetched over the network, which this lane must not depend on; the bugs these pin were never "wrong data" but "the call is refused before it is attempted". Rebased onto edee560. The conflict with the merged relative-folder-path tests (tinyhumansai#5959) was textual, not semantic: both sides append independent tests to the tail of this file and share the same setup boilerplate, which is what git interleaved. Resolved by taking main's file whole and appending these two tests, so both sets survive intact.

Summary
Backfills e2e coverage for five of six merged PRs whose changed behaviour no e2e test exercised. Test-only — no product code is touched.
The audit behind this found the same trap three times: the changed symbols were already present in e2e files, so the repo's domain e2e gate (a literal string match over
tests/**/*_e2e.rs) read them as covered, while nothing drove the changed path.run_subagentin 9 e2e filessettings/profilesroute in a Playwright specWhat each test drives

turn_dispatch_guardaround the call. That is the load-bearing part:run_subagent's own comment says the gate is a no-op outside a turn scope, so the nine existing tests that call it take theAllowbranch and assert nothing. Both also assert the provider was never reached — the refusal is meant to cost nothing, so a gate that let the dispatch reach the model before erroring would still be the defect #5810 fixed.Each test drives an allowed dispatch through the same guard first. A gate that refused unconditionally would fail on that half, so neither test can pass for the wrong reason.
#5772 — probe outcomes (

That last pair is the point of the enum: a slow server is not a failed one, and collapsing them is what made the supervisor tear down working sessions and report a drop it never observed (#5636). The existing test only ever asked.is_alive(), which isfalsefor all three non-alive variants alike.Duration::ZEROis used rather than a small window so the timeout arm is deterministic, not racy.supervisor_default_probe_window_stays_eight_secondspins the defaultb44b958drestored.

So something other than the documented path prunes the entry.
