test: fix flaky/stale tests blocking Rust E2E + coverage CI on main

[sanil-23]

Summary

Fix four pre-existing, unrelated test failures that are red on main and block CI for every PR. All are test-only changes — no production code is touched.

• Rust E2E (mock backend) [required check] — align the credentials e2e test with fix(auth): gracefully drop OAuth profiles with missing access_token #3125's "gracefully drop OAuth profile missing access_token" behavior.
• Rust Core Coverage — fix a flaky env-var race in the inference-provider coverage suite.
• Frontend Coverage (Vitest) — fix two stale/mismatched assertions (memoryGraphLayout radii after feat(memory): redesign sync flow with ingest_summary, graph improvements, audit log #3113; a curly-vs-straight apostrophe in OpenhumanLinkModal notifications).

Problem

Each failure is independent and pre-existing on main; none is caused by this PR:

1. Rust E2E (mock backend) (required) — fix(auth): gracefully drop OAuth profiles with missing access_token #3125 changed AuthProfilesStore::load to drop an OAuth profile missing its access_token (instead of erroring) and removed the "OAuth profile missing access_token" string, but left credentials_profile_store_recovers_dropped_entries_empty_files_and_datetime_errors asserting .load().expect_err(...). load() now returns Ok, so expect_err panics (…:5449 unwrap_failed, 49 passed / 1 failed). This blocks the required check on every PR.

2. Rust Core Coverage — inference_provider_admin_round22_raw_coverage_e2e mutates OPENHUMAN_WORKSPACE / OPENHUMAN_OLLAMA_BASE_URL / PATH as process-global env via EnvVarGuard. Its own SAFETY comments say it is "validated with --test-threads=1", but cargo llvm-cov runs the binary's 5 tests in parallel, so the global mutations race and one test reads another's workspace/config — surfacing as a flaky assert object_error.contains("nested provider failure") failure. (Passes in isolation; fails under the parallel coverage run.)

3. Frontend Coverage — memoryGraphLayout.test.ts — feat(memory): redesign sync flow with ingest_summary, graph improvements, audit log #3113 redesigned nodeRadius from shrinking (max(4, 10 - level*0.8)) to growing (5 + level*2.5, chunk 4→3, new source→16) but did not update the test, which still asserted the old values (expected 5 to be 10).

4. Frontend Coverage — OpenhumanLinkModal.notifications.test.tsx — the success-copy query used a curly apostrophe (U+2019) in "didn't", but en.ts renders a straight apostrophe (U+0027), so getByText never matched (two cases failed).

Solution

1. Update the credentials e2e assertion to the new contract: the missing-access-token profile is dropped, so the load succeeds, the profile + its active pointer are purged, and the drop is persisted — mirroring the existing legacy:bad-kind drop assertions in the same test.
2. Add an env_lock() mutex (the exact pattern every other *_e2e.rs already uses) and take it at the top of each of the 5 inference tests, so the suite is serialized regardless of the runner's thread count.
3. Realign memoryGraphLayout radius expectations to the shipped formula (L0→5, L3→12.5, L99→252.5, chunk→3; contact→9 unchanged).
4. Use a straight apostrophe in the notification-success regex to match the rendered en.ts string.

Submission Checklist

• Tests added or updated (happy path + at least one failure / edge case) — realigns four pre-existing tests to merged behavior; the drop/recover, growing-radius, and notification-success paths are all asserted.
• Diff coverage ≥ 80% — N/A: test-only change (changed lines are test code executed by the tests themselves).
• Coverage matrix updated — N/A: no feature row added/removed/renamed; aligns existing tests with already-merged behavior.
• All affected feature IDs listed under ## Related — N/A: no matrix feature touched.
• No new external network dependencies introduced.
• Manual smoke checklist updated if this touches release-cut surfaces — N/A: test-only.
• Linked issue closed via Closes #NNN — N/A: no tracking issue; fixes CI regressions left by #3125 and #3113.

Impact

• Platform: none at runtime — test-only.
• CI: unblocks the required Rust E2E (mock backend) check and greens the Rust Core Coverage + Frontend Coverage jobs, all of which are currently red on main for every PR.

Related

• Follow-up to fix(auth): gracefully drop OAuth profiles with missing access_token #3125 (Rust E2E credentials test) and feat(memory): redesign sync flow with ingest_summary, graph improvements, audit log #3113 (nodeRadius redesign) — both changed behavior without updating these tests.
• Closes:
• Follow-up PR(s)/TODOs: none.

Summary by CodeRabbit

• Bug Fixes
  • Improved resilience when loading incomplete OAuth profiles: invalid profiles are now dropped and references purged so loading succeeds instead of failing.
• User Interface
  • Minor UI copy tweak for the notification message to match displayed text.
  • Adjusted memory graph node sizing so summary nodes scale with level and chunk/contact nodes use fixed sizes.
• Tests
  • Serialised environment access in tests to prevent interference from concurrent runs.

📝 Walkthrough

Walkthrough

Tests updated: env-var mutations serialized via a global ENV_LOCK; OAuth-profile load test now expects incomplete OAuth profiles to be dropped and persisted JSON rewritten; two UI tests use ASCII apostrophes; memoryGraphLayout test now asserts growing summary node radius with level and fixed chunk/contact radii.

Serialize env var mutations with ENV_LOCK tests/inference_provider_admin_round22_raw_coverage_e2e.rs	Add OnceLock<Mutex<()>> ENV_LOCK, env_lock() helper, and acquire the lock at several #[tokio::test] starts to serialize process-global env var changes.
OAuth profile missing access_token test expectations tests/config_auth_app_state_connectivity_e2e.rs	Change test to expect successful AuthProfilesStore load that drops incomplete OAuth profiles, removes corresponding active_profiles entries, and rewrites persisted auth-profiles.json without the dropped profile.
UI notification apostrophe fixes app/src/components/__tests__/OpenhumanLinkModal.notifications.test.tsx	Update expected notification text to use ASCII apostrophe (“didn't”) in initial success and retry-success assertions.
memoryGraphLayout nodeRadius expectations app/src/components/intelligence/memoryGraphLayout.test.ts	Update nodeRadius test: summary node radius increases with level; chunk and contact node radii are fixed to specific values.

🐰 A mutex snug for envs at play,
Tokens dropped when they've gone astray.
Apostrophes fixed, nodes grown tall,
Tests now sing—no sudden fall. 🥕

@sanil-23 hey! the code looks good to me. The three assertions are exactly right — profile dropped from the map, active pointer purged, persisted JSON cleaned up. Mirrors the existing bad-kind drop pattern cleanly.

There are some CI failures (Playwright lane 1, Frontend Coverage, Rust Core Coverage) but they look pre-existing on main and unrelated to this test-only Rust change — the Rust E2E check itself is now green, which is the whole point of this PR. Once those other failures are resolved on main and the full suite is green, I'll come back and approve this.

tests/inference_provider_admin_round22_raw_coverage_e2e.rs (1)

84-89: 💤 Low value

Consider clarifying the caller's responsibility in SAFETY comments.

The SAFETY comments claim "mutation is serialized by env_lock()" but EnvVarGuard itself doesn't enforce that the lock is held—it relies on the caller convention. While this is acceptable for test-only code and all current usages correctly hold the lock, the comments could be clearer about the contract.

📝 Optional: Make the caller contract more explicit

             Some(value) => {
-                // SAFETY: mutation is serialized by `env_lock()` (see below).
+                // SAFETY: Caller must hold `env_lock()` to serialize this mutation.
                 unsafe { std::env::set_var(self.key, value) }
             }
             None => {
-                // SAFETY: mutation is serialized by `env_lock()` (see below).
+                // SAFETY: Caller must hold `env_lock()` to serialize this mutation.
                 unsafe { std::env::remove_var(self.key) }
             }

Alternatively, for stronger type safety, EnvVarGuard::set/unset could require a &MutexGuard<'static, ()> parameter to prove lock ownership at compile time, but that's likely overkill for test utilities.
