Fleet row cx02883e0efb. Investigates #361: startup identity resolution, stale MCP processes after upgrade or resume, cycling options, and tests to add. Documentation only. Proof: test -s docs/investigations/issue-361-mcp-identity-cycle.md && grep -qiE 'identity' docs/investigations/issue-361-mcp-identity-cycle.md (passed).

Summary by CodeRabbit

• Documentation
  • Added an investigation guide explaining how MCP sessions, process lifetimes, and identity context can lead to stale or split identity diagnostics.
  • Documented operator options for reconnecting with the intended context, restarting a host with stale launch context, or deliberately starting a new identity.

Walkthrough

The pull request adds an investigation document about MCP home adoption, identity resolution, and process lifetimes. It records operator options and proposed tests. It states that no runtime reproduction or identity mutation was performed.

Changes: MCP identity-cycle investigation

Layer / File(s)	Summary
Document identity resolution and lifecycle docs/investigations/issue-361-mcp-identity-cycle.md	The document traces MCP home and identity resolution, distinguishes retained MCP processes from fresh CLI and statusline processes, and describes daemon boundaries and diagnostic limits. It records operator workflows, unimplemented rebind and re-exec considerations, proposed tests that were not run, and a documentation-artifact check.

Full details: Title check

Explanation

The title "Investigate MCP identity cycling for #361" states the main change: an investigation document for issue #361 on MCP identity cycling. The raw summary confirms the change adds only an investigation document, and the PR objectives confirm it is documentation-only, covering startup identity resolution, stale MCP processes, and cycling options. The title is specific, concise, and accurate, and it contains no vague terms.

Refresh the stale session-key citation for revision 42d4346.

src/session.rs:1094 belongs to the Copilot/VS Code adapter loop, not the Claude PID-file lookup. Cite the lookup at src/session.rs:1103 or use the stable claude_code_session_from_pidfile symbol.

The other cited examples identify related code; the claims about src/mcp.rs:1598, src/mcp.rs:1297, and src/session.rs:1906 are not supported.
