+# Notifier-First Runtime Roadmap
+
+## Goal
+
+Define a generic, upstream-safe path for real-time agent message awareness that does not depend on fragile turn hooks or project-specific wrappers.
+
+This roadmap focuses on reusable primitives that can be implemented in `agentic-comm` and consumed by any runtime.
+
+## Problem Statement
+
+Current coordination patterns often rely on one of two brittle approaches:
+
+1. Poll-only loops that require frequent manual turns.
+2. Hook-triggered prompt injection with weak lifecycle guarantees.
+
+Both patterns can fail across restarts, process churn, and multi-runtime environments.
+
+## Target Architecture (Generic)
+
+Layered model:
+
+1. Store + daemon: durable message persistence and low-latency relay.
+2. Notifier: transforms incoming deltas into normalized awareness events.
+3. Runtime adapter: consumes events and triggers agent-visible context updates.
+4. Session workflow: clear start/stop/recover commands with health checks.
+
+The key contract is an explicit event envelope between notifier and runtime adapter, not implicit behavior.
+
+## Proposed Upstream Scope
+
+### Phase 1: Stable Read/Delta Primitives
+
+- Add first-class id-based delta reads (`after_id`) for channel polling and streaming.
+- Keep timestamp-based reads, but document id-based reads as preferred for restart safety.
+- Guarantee deterministic ordering in CLI output (`id` ascending by default).
+
+Deliverables:
+- CLI options and docs updates.
+- Regression tests for restart and cursor handoff behavior.
+
+### Phase 2: Generic Notifier Event Envelope
+
+- Define a neutral text+json event envelope for runtime adapters.
+- Include canonical fields:
+  - `message_id`
+  - `channel_id`
+  - `channel_name`
+  - `sender`
+  - `timestamp`
+  - `content`
+  - `read_cmd`
+  - `reply_cmd`
+  - `fetch_cmd`
+  - `execution_hint`
+
+Deliverables:
+- Public envelope spec in docs.
+- Example producer/consumer flow.
+
+### Phase 3: First-Party Notifier CLI Surface
+
+- Add generic notifier commands (illustrative):
+  - `acomm notifier run`
+  - `acomm notifier status`
+  - `acomm notifier stop`
+- Support output targets:
+  - stdout (jsonl)
+  - file queue (append-only)
+
+Deliverables:
+- CLI implementation with restart-safe cursors.
+- Integration tests for queue output and dedupe.
+
+### Phase 4: Runtime Lifecycle Contract
+
+- Document a standard lifecycle for stream/runtime coordination:
+  - `start`
+  - `wake/recover`
+  - `stop`
+  - `health`
+- Provide generic runbook-level guidance that any runtime can follow.
+
+Deliverables:
+- Public runbook patterns.
+- CLI examples that avoid project/person-specific naming.
+
+## Non-Goals
+
+- No runtime-specific terminal injection implementation in core.
+- No project-specific launcher conventions.
+- No identity/personality-specific assumptions in examples.
+
+## Acceptance Criteria
+
+1. Realtime awareness survives process restarts without duplicate floods or missed messages.
+2. Id-based cursor handoff is deterministic across notifier restarts.
+3. The same notifier event stream can be consumed by multiple runtimes without schema changes.
+4. Public docs and examples remain identity-neutral and environment-agnostic.
+
+## Compatibility
+
+- Existing `send/receive/chat` flows remain valid.
+- New notifier features layer on top of current message and daemon model.
+- Migration path is additive: users can adopt phases incrementally.
