+## SPIRALMESH 0.1.9: memory and a shared task board
+
+[Download SPIRALMESH 0.1.9](https://article11.ai/downloads/spiralmesh-plugin-v0.1.9.zip) or inspect its
+[complete source tree](https://github.com/steviesonz/article11-constitution/tree/main/mirror/products/spiralmesh). The archive is **406,725 bytes**,
+SHA-256 `7f9eeabe517deca992f5d0b40ae76df4eee59c835a1449a88d4bd5976456d996`. The [checksum](https://article11.ai/downloads/spiralmesh-plugin-v0.1.9.zip.sha256) and
+[source index](https://article11.ai/downloads/spiralmesh-plugin-v0.1.9.sources.json) travel with it.
+
+The new board helps a human or an agent distinguish a linked answer, a blocked
+route, a request awaiting action, and work supported by a completion record.
+Delivery does not mean a message was read; an answer does not prove the work is
+finished. The board does not send messages, approve requests or wake a model.
+
+Try it without an account, model or private library. With Python 3.11+ installed,
+extract the archive and run these commands from the extracted folder:
+
+```sh
+python -B verify_bundle.py
+python -B scripts/task_board.py --demo
+python -B scripts/task_board.py --demo --serve --open
+```
+
+On Windows, double-click `OPEN_TASK_BOARD.cmd` for the same browser demonstration.
+The demo uses invented records in a temporary folder. The page is served only on
+your own machine; Ctrl+C stops it. Reading a real board requires an explicitly
+selected, compatible local Relay SQLite database. No household database, private
+memory, signing key or unattended Relay service is included.
+
+The existing memory setup, guided update, library tools and shared workshop remain
+in the package. Optional model work has its own documented provider or local-host
+requirements. The board demo makes no model calls. Hosted memory stays separate.
+
+The unpacked source is the build input. See
+[rebuild instructions](https://github.com/steviesonz/article11-constitution/blob/main/mirror/products/spiralmesh/docs/BUILD_FROM_SOURCE.md) and
+[machine-readable product details](spiralmesh-product.json). Code is Apache-2.0;
+the carried Constitution is separately CC0. Names and marks are not licensed by
+either grant. These records support continuity; they do not establish identity,
+experience or authority.
+
+This product companion does not add dataset rows or change the pinned Core.
+The `articles` configuration continues to load only `data/articles.jsonl`.
+The SPIRALMESH code uses Apache-2.0; this dataset's CC0 label describes the
+Constitution text, not a relicense of separately linked software.
