Briefing Mode — Phase 1: anchor + correspondent roles

[dotdevdotdev]

First buildable slice of Briefing Mode (asymmetric-verbosity orchestration), per the feasibility report at docs/wiki/research/briefing-mode-feasibility.md (§9 Phase 1).

Goal

Ship the working loop with ~zero new code: two role files + a filesystem-dropbox awareness convention. A terse anchor orchestrator fans out verbose correspondent worktrees, which file deep reports to a dropbox; the anchor pulls + briefs the human asymmetrically (voice headline + text card) on the human's cue.

Scope

• In: anchor role (replaces orchestrator persona), correspondent role (stacks on the worktree-session safety rail), filesystem dropbox at ~/.agentwire/research/<anchor-session>/ documented in the roles.
• Out (Phase 2/3): passive ingest message kind + msg pull, MCP worktree_create + --prompt seed flag, unified say(display=), blessed dropbox resolver. Tracked separately when started.

Verification

Roles parse + are discoverable; correspondent ADDS to worktree-session (safety rail kept), anchor REPLACES the orchestrator persona; installed CLI exposes both via agentwire roles list.

PR opened with Phase 1.

Breadcrumb (PR-open): Shipped the two role files with no new code — awareness via filesystem dropbox.

• anchor.md: terse persona (replaces orchestrator); asymmetric say+portal_notify brief; fans out correspondents; pulls dropbox on human's cue only; teardown via worktree --remove.
• correspondent.md: exhaustive; stacks on worktree-session rail; files report to ~/.agentwire/research/<anchor-session>/; signals passively (file = signal, no driving msg); skips draft PR for research-only.

Verified role stacking (correspondent adds to rail) vs replacement (anchor replaces persona), both exposed by installed CLI after rebuild. Phase 2 = passive ingest kind + worktree_create.
