fix(edge): retry+degrade side-effect POSTs; finish ACTIVITY-WP-0027

Consistency sweep and recently-on-scope retry transient 502/503/504 then
return a degraded context snapshot instead of thrashing Temporal.

+# Edge relay resilience (ACTIVITY-WP-0027-T06)
+
+**Audience:** operators and agents debugging high-frequency activity-core jobs  
+**Scope:** railiance01 `actcore-statehub-edge-relay` + worker `STATE_HUB_URL`
+
+## Topology
+
+```text
+actcore-worker
+  STATE_HUB_URL=http://actcore-statehub-edge-relay:8000
+        │
+        ▼
+  edge relay (cluster)
+    · GET allowlist → upstream or stale read-cache
+    · POST side-effects → upstream (or 503 if busy/unreachable)
+        │
+        ▼
+  state-hub service (cluster DNS state-hub.state-hub.svc …)
+    · may depend on tunnel / central hub posture
+```
+
+Host rein-aharness should prefer the **same edge ClusterIP** (or `k8s://…edge-relay:8000`)
+so completion events outbox when central hub is flaky — see
+`docs/llm-connect-host-access.md`.
+
+## Resolver classes
+
+| Class | Examples | Hard-fail? | Notes |
+| ----- | -------- | ---------- | ----- |
+| **GET reads** | `fi_brief_status`, `domain_summary`, `state_summary` | Soft by default (`{}` / empty) unless `required: true` | Edge may serve **stale cache** (`X-StateHub-Edge-Cache: stale`) |
+| **Side-effect POSTs** | `consistency_sweep_remote_all`, `recently_on_scope_hourly` | After retries: **degrade** by default | See env below |
+| **Required pure reads** | `todo_md_staleness` when enabled | Yes if `required: true` | Prefer not to make hub-only reads required without cache |
+
+## Side-effect POST behaviour (worker)
+
+Implemented in `context_resolvers/state_hub.py` (`_post_json`):
+
+1. **Retry** transient `502/503/504` and network/timeout errors  
+   (`STATE_HUB_POST_RETRIES`, default **3**; backoff
+   `STATE_HUB_POST_RETRY_BACKOFF_SECONDS`, default **2s** × attempt).
+2. If still failing and degrade is on (`STATE_HUB_SIDE_EFFECT_DEGRADE` default
+   **true**, or per-source `params.degrade_on_unavailable`):
+   - **consistency_sweep:** returns
+     `{exit_code: 75, lock_skipped: true, repos_processed: [], degraded: true, …}`
+     so the workflow **completes** without Temporal ApplicationError storms.
+   - **recently_on_scope:** returns
+     `{generated: [], failed: [{reason: edge_unavailable}], degraded: true, …}`.
+3. Set `degrade_on_unavailable: false` on a definition (or env
+   `STATE_HUB_SIDE_EFFECT_DEGRADE=false`) to keep hard-fail + Temporal retry
+   after in-resolver attempts.
+
+## Operator checks
+
+```bash
+# Edge health (from host with ClusterIP or kubectl exec)
+curl -sS http://<edge-cluster-ip>:8000/edge/health | python3 -m json.tool
+
+# Worker still pointing at edge
+kubectl -n activity-core exec deploy/actcore-worker -- env | grep STATE_HUB
+
+# Recent consistency fires should COMPLETE even when edge was briefly 503
+# (look for degraded:true in context_snapshot if all retries failed)
+```
+
+## What edge 503 usually means
+
+- Upstream hub slow / lock held / temporary overload on
+  `/consistency/sweep/remote-all` (large fleet).
+- Upstream unreachable; edge refuses to invent a false success for POSTs.
+- Outbox backlog (see `edge/health` → `outbox.pending_count`) is **write**
+  backlog for queued progress — separate from sweep POST 503.
+
+## Non-goals
+
+- Making the edge invent successful sweep results when nothing ran.
+- Public exposure of State Hub or edge.
+- Replacing Temporal schedules with workstation heartbeats.
