> Aura: a calm, serverless baby and child log (PWA) with German checkup and vaccination reminders

Version 1, digest sha256:ea5843ce68206b2d47a94f00a41ea7675ae990f52db2da70c3942046dfc1885d. product pack · 74 obligations (74 decided, 0 default, 0 open, 5 unchecked) · 10 assumptions (6 monitored) · 288/288 checks trace to an obligation.

## Build this pack

For coding agents whose user shared https://symbola.sh/packs/spikinglabs/aura/ and wants it built. Run these steps yourself; ask the user only for the language if they have not named one.

1. Install the Symbola CLI (Python 3.11+): `uv tool install symbola` (or `pipx install symbola`). Not `pip install symbolon`: that PyPI name is another project.
2. Download the pack: `symbola pull spikinglabs/aura --dest spec`.
3. Read `spec/AGENTS.md` and follow it. Build only from `spec/`: don't look for the original product's source, the registry repository (it holds holdout tests) or other builds. Packs released before the rename say `symbolon <command>`: run `symbola <command>` instead.
   This is a product pack: `spec/PRODUCT.md` describes the whole product (its shape, surfaces and flows). Build that product, in the user's stack, with the components below as its core. Don't build a demo page around the components instead.
4. Build each component in its own folder and run its checks as you go, fixing what fails:

       symbola impl-init impl/ai-redaction --contract spec/components/ai-redaction/versions/1
       symbola test spec/components/ai-redaction/versions/1 impl/ai-redaction

   In Python, define `run(input)` in `impl.py`: it takes and returns a dict, and raises `ValueError` for input the contract rejects. Pin third-party packages with `==` in `requirements.lock`. In another language, set `language = "command"` and `command = [...]` in `symbolon-impl.toml`; the program reads one JSON input per line on stdin and writes `{"output": ...}` per line. A component whose `symbolon.toml` says `driver = "cli"` is a command line: build the real program, set `command` to it, and symbola runs it once per check.
5. When every component passes, run `symbola keygen` once, then for each component `symbola attest spec/components/ai-redaction/versions/1 impl/ai-redaction -o attestations/ai-redaction.json`. On macOS, attest needs Docker running and accepts Python, Node or a static Linux binary (for Go, `GOOS=linux`); `symbola test` runs the same checks without it.

You are done when every flow in `spec/PRODUCT.md` works in the product you built and attest reports PASSED for every component. Write open questions and the readings you chose in `NOTES.md`. Every command is described at https://kausalflow.github.io/symbola/cli/.
