From the SKILL.md

# myDATA invoicing (timologio + ERP)

`ROOT` = this folder. Run everything with `python3 ROOT/scripts/issue.py ...`.
Config in `ROOT/config.json`, credentials in `ROOT/.env` (never read aloud, never printed).

Preconditions: Chrome with the user logged in at https://mydata.aade.gr/timologio.
The browser client is `ROOT/scripts/timologio_client.js`; inject its full text with the
JavaScript tool into the timologio tab after every navigation.

## The rule

Three actions are irreversible: `TL.issue()`, `issue.py erp --yes`, sending the email.
Each one happens only after the user has seen the result of the previous step and said
«ναι» in the chat. Never chain them without that.

## Flow

1. `issue.py new --vat <ΑΦΜ> --item <key> --net <amount> [--descr] [--notes] [--payment]`
   Prints the draft id and a SPEC json.
2. Customer unknown to timologio? Open `/timologio/customer/NewCustomer`, inject the
   client, `TL.createCustomer(vat, email)` fills it from the tax registry. Show the data,
   then `TL.saveCustomer()`. Record the code from the green banner:
   `invoice_store.save_customer(vat, timologio_code=N, name=..., street=..., ...)`.
3. Open `/timologio/invoice/newinvoice`, inject, `await TL.build(spec)`. Check
   `totals` against `spec.expect`. `await TL.preview()`, `TL.showPdf()`, screenshot, show
   the user. `issue.py previewed <id>`. `TL.hidePdf()`.
4. Wait for «ναι». `await TL.issue()` → `{mark, aa}`. At once:
   `issue.py issued <id> --mark <mark> --aa <aa>`.
