// Edit-agent dialog coverage (Phase 1B.3b-pre). Written against TODAY'S
// EditAgentDialog, before the B3b re-host, so the re-host is guarded by a
// pre-existing spec rather than one written alongside it.
//
// Mock-boundary caveat: the e2eBridge `update_managed_agent` handler echoes
// name/model/systemPrompt/envVars/respondTo/respondToAllowlist into the
// mock store — it does NOT
// model the diff-based partial-update wire semantics (change-detected-or-omit,
// tri-state provider, harnessOverride derivation), and it ignores
// agentCommand/harnessOverride entirely. This spec therefore pins UI behavior
// (open → edit → save → persisted in UI), not wire semantics. The inherit
// toggle is not reachable here at all (see the routing pin below) — its
// behavior is covered by B3b's component-level pinning test (inherit-toggle
// → gate → submit); wire semantics stay component-test territory
// (personaRuntimeModel.test.mjs).
