Confirm the W33 spike as cold-start variance and preserve a repeatable diagnosis protocol.
- Record five sequential phase-timed samples and the 20.5-second median threshold.
- Link the controlled remeasurement protocol from the testing guide.
- Explain the timing snapshot handoff and why incomplete CI artifacts were not published.
- Preserve the no-appeasement requirement beside boot-smoke phase timing.

Investigated whether --login in TerminalService first-prompt latency is a meaningful contributor and added a one-time diagnostic hint plus documentation of findings.
- Add SLOW_LOGIN_PROFILE_HINT_MS (2000ms) threshold and one-time, non-blocking console.info hint in createSession()'s PTY onData handler when a login shell is slow to produce first output
- Track spawnStartedAt and loginProfileHintLogged per session, and whether the succeeding spawn attempt used --login, without altering spawn args, timeouts, or the retry-without-login fallback
- Add regression tests covering the slow-login-profile hint behavior in terminal-service.test.ts
- Document the investigation and findings in docs/solutions/developer-experience/login-shell-profile-latency.md and link it from docs/dashboard-guide.md
- Add a patch changeset for @runfusion/fusion describing the new server-log hint
