+## [1.1.0] - 2026-06-18
+
+Worker consolidation: cut the long-running worker fleet's resident memory by
+hosting co-resident workers in shared supervisor processes instead of one OS
+process per worker. Behaviour-preserving — workers run the same code; only
+*where* they are hosted changes, and any worker remains extractable back to its
+own unit.
+
+### Added
+- `decnet supervise <group>` — hosts a co-resident worker group in one process,
+  paying the Python import floor and the DB connection pool once instead of once
+  per worker. Groups: `batch` and `cpu`.
+- `decnet.supervisor` — in-process supervision primitive: each worker runs in its
+  own restart loop with exponential backoff (in-process `Restart=on-failure`),
+  run concurrently so one worker crashing never cancels its siblings.
+  Deliberately not `asyncio.TaskGroup`, whose all-or-nothing cancellation would
+  break worker isolation.
+- `decnet.offload` — shared-pool CPU-kernel offload. The `cpu` group runs its two
+  O(n²) connected-components kernels (`cluster_observations`, `cluster_identities`)
+  in one shared `ProcessPoolExecutor` (forkserver) so they run in parallel
+  instead of serialising under the GIL. Inline when no pool is installed, so
+  standalone workers and tests are unchanged.
+- systemd units `decnet-supervise-batch.service` and `decnet-supervise-cpu.service`
+  (auto-rendered by `decnet init`); each `Conflicts=` the individual units it
+  replaces, preventing accidental double-run.
+
+### Changed
+- `decnet.topology` no longer eagerly imports the topology generator (and the
+  SQLModel ORM behind it) at package import. `generate` is now a lazy PEP 562
+  re-export; the public API is unchanged.
+
+### Performance
+- **batch** group (`reconcile` + `enrich` + `orchestrate` + `mutate`):
+  509 MB across 4 processes → **129 MB** in one. **−380 MB (75%)**, verified live.
+- **cpu** group (`clusterer` + `campaign-clusterer` + `attribution` +
+  `reuse-correlate`): 502 MB → **~146 MB** (incl. forkserver). **−357 MB (71%)**,
+  verified live.
+- Fleet total: **2.57 GB → ~1.83 GB (−737 MB)**.
+
+### Notes
+- `webhook` (external-HTTP egress; needs hard timeouts) and `canary` (manages its
+  own repo) intentionally remain standalone for now.
+- `bus`, `api`/`web`, `profiler`, and `ttp` remain separate by design (broker /
+  multiprocess servers / heavy resident state + sustained CPU).
