Struct DispatchContext 

pub struct DispatchContext {
    pub conn_id: u64,
    pub reads: ReadContext,
    pub diff: Option<ProgrammaticDiffBus>,
    pub review: ReviewHandle,
}

The state the dispatcher needs to answer tools/call: the read tools’ ReadContext + the write bus. Built once at server spawn and shared (behind an Arc) across connections. The I1 methods (initialize / tools/list / prompts/list) ignore it.

Fields

conn_id: u64

D-fix.6: the originating connection id — assigned per WS connection by the server (serve_connection clones the shared context and stamps this). Carried into openDiff (tags the diff’s origin_session) and the close tools (scopes teardown to THIS connection’s diffs), so one agent session can never tear down another’s diffs. 0 for the shared boot context + dispatch tests (no real connection).

reads: ReadContext

Read-tool services (cache + generic buffer-store / diagnostics + workspace config). BC.3b / AG-2b: the write bus now rides inside reads.editor (a lattice_agent::EditorAccess) — write tools call ctx.reads.editor.open_file(...) etc. directly, no separate bus field.

diff: Option<ProgrammaticDiffBus>

I4 openDiff host-drained bus ([ProgrammaticDiffBus]). None until boot wires it (and in dispatch tests) — openDiff then returns a graceful isError: true. Separate from writes because openDiff is blocking + carries lattice-diff types that can’t cross the Effect boundary (so it can’t ride the I3 handler bus).

review: ReviewHandle

D-fix.6 follow-up: the shared pending-review tracker. openDiff brackets its blocking await with review.begin(), so the modeline shows a ◆ review badge while the agent is blocked on the user — derived entirely from claude-code’s own openDiff lifecycle (no host signal).
