Follow-up to #2874 (RC: CR2 #11826 + Researcher #11827).

Problem

The previous hasHistory check used locator("div").count() > 3, an arbitrary heuristic that does not actually prove the seeded transcript hydrated.

Fix

Replace the heuristic with explicit Playwright visibility assertions for the messages seeded by seedChatHistory() in beforeAll:

• desktop: assert Hello from seed and Echo: Hello from seed are visible.
• mobile: assert Hello from mobile seed and Echo: Hello from mobile seed are visible.
• both: assert the empty-state placeholder (Send a message to start chatting.) is hidden.

Path-filter / CI proof

Changes to canvas/e2e/chat-*.spec.ts already trigger the E2E Chat lane via the chat-spec-direct block in .gitea/workflows/e2e-chat.yml (landed in #2874). This PR should therefore execute the real Playwright E2E Chat job, not a path-filter no-op.

Routing

2-genuine review (CR2 + Researcher). Do not self-merge.

fix(canvas/e2e): assert seeded chat history text, not arbitrary div count ... 072676a620

CR2 #11826 + Researcher #11827 RC: the previous hasHistory check used
, which is an arbitrary heuristic and not a
real proof that the seeded transcript hydrated. Replace it with explicit
Playwright visibility assertions for the seeded user + agent messages,
and assert the empty-state placeholder is hidden.

- desktop: assert 'Hello from seed' / 'Echo: Hello from seed' visible.
- mobile: assert 'Hello from mobile seed' / 'Echo: Hello from mobile seed' visible.
- Both: assert empty-state text is hidden.

The path-filter trigger for canvas/e2e/chat-*.spec.ts is already in
.gitea/workflows/e2e-chat.yml (chat-spec-direct block) so this PR will
execute the real Playwright E2E Chat lane.

APPROVED on 072676a6.

Verified the follow-up removes the brittle div.count() > 3 heuristic and asserts the actual seeded transcript instead. Desktop seeds Hello from seed / Echo: Hello from seed; mobile seeds Hello from mobile seed / Echo: Hello from mobile seed; each spec now requires those messages visible and the empty placeholder hidden. That matches the fixture and is not an over-constrained conditional case.

Verified on actual E2E Chat run 366964 / job 502266: the no-op path-filter step was skipped, npx playwright test e2e/chat-desktop.spec.ts e2e/chat-mobile.spec.ts e2e/chat-separation.spec.ts executed, 26 tests ran, and the changed tests passed specifically (chat-desktop.spec.ts:74, chat-mobile.spec.ts:53). Scope is test/workflow-only.

APPROVED on 072676a620.

Verified the test-only robustness change:

• The desktop and mobile chat-panel load tests now assert the seeded user+agent messages are visible and the empty-state placeholder is hidden, instead of using the brittle locator('div').count() > 3 heuristic.
• Those assertions match the existing seeded state from seedChatHistory(...) and are neither under-constrained nor over-constrained for this fixture.
• Verified on the actual E2E Chat run 366964 / job 502266: the no-op path-filter step was skipped because chat==true, Run Playwright E2E tests executed, both changed chat load tests passed, and the job reported 26/26 passing.

This now pins the intended seeded-history behavior directly with real Playwright proof.
