Merge pull request 'docs: update poller to dispatcher architecture (closes #4)' (#5) from fix/update-poller-docs into main

Replace flag-file + heartbeat approach with the production dispatcher
pattern: poller triages notifications and spawns isolated agents
directly via openclaw cron. Adds assignment scan for self-created
issues. Response time ~15-60s instead of ~30 min.

 Setup: add a webhook on each Gitea repo (or use an organization-level webhook)
 pointing to `https://your-openclaw-host/hooks/gitea`. OpenClaw handles the rest.
 
-#### Option B: Notification Poller (Local Machine Behind NAT)
+#### Option B: Notification Poller + Dispatcher (Local Machine Behind NAT)
 
 If your OpenClaw runs on a dedicated local machine behind NAT (like a home Mac
 or Linux workstation), Gitea can't reach it directly. This is our setup —
 OpenClaw runs on a Mac Studio on a home LAN.
 
-The solution: a lightweight Python script that polls the Gitea notifications API
-every few seconds. When new notifications appear, it writes a flag file that the
-agent checks during heartbeats.
+The solution: a Python script that both polls and dispatches. It polls the Gitea
+notifications API every 15 seconds, triages each notification (checking
+assignment and @-mentions), marks them as read, and spawns one isolated agent
+session per actionable item via `openclaw cron add --session isolated`.
+
+The poller also runs a secondary **assignment scan** every 2 minutes, checking
+all watched repos for open issues/PRs assigned to the bot that were recently
+updated and still need a response. This catches cases where notifications aren't
+generated (e.g. self-assignment, API-created issues).
 
 Key design decisions:
 
-- **The poller never marks notifications as read.** The agent does that after
-  processing. This prevents lost notifications if the agent fails to process.
-- **It tracks notification IDs, not counts.** Only fires on genuinely new
-  notifications, not re-reads of existing ones.
-- **Flag file instead of wake events.** We initially used OpenClaw's
-  `/hooks/wake` endpoint, but wake events target the main (DM) session — any
-  model response during processing leaked to DM as a notification. The flag file
-  approach is processed during heartbeats, where output routing is controlled.
+- **The poller IS the dispatcher.** No flag files, no heartbeat dependency. The
+  poller triages notifications and spawns agents directly.
+- **Marks notifications as read immediately.** Each notification is marked read
+  as it's processed, preventing re-dispatch on the next poll.
+- **One agent per issue.** Each spawned agent gets a `SCOPE` instruction
+  limiting it to one specific issue/PR. Agents post results as Gitea comments,
+  not DMs.
+- **Dedup tracking.** An in-memory `dispatched_issues` set prevents spawning
+  multiple agents for the same issue within one poller lifetime.
+- **`--no-deliver` instead of `--announce`.** Agents report via Gitea API
+  directly. The `--announce` flag on isolated sessions had delivery failures.
+- **Assignment scan filters by recency.** Only issues updated in the last 5
+  minutes are considered, preventing re-dispatch for stale assigned issues.
 - **Zero dependencies.** Just Python stdlib. Runs anywhere.
 
-Tradeoff: notifications are processed at heartbeat cadence (~30 min) instead of
-realtime. For code review and issue triage, this is fine.
+Response time: ~15–60s from notification to agent comment (vs ~30 min with the
+old heartbeat approach).
