-### 9. Principal Legislation (`frl_principal_legislation`)
+### 9. Advice under Development (`advice_under_development`)
+
+The ATO's public register of the public advice and guidance it is **currently developing** — the pipeline behind the other splits. Sourced from the [Advice under development program](https://www.ato.gov.au/about-ato/ato-advice-and-guidance/advice-under-development-program) pages rather than the Legal Database. One row per advice *product*: a single `[NNNN]` issue often covers several products (draft Determination, final Ruling, Practice Statement) with separate expected completion dates, so `Issue_Number` is **not** a primary key — key on `Source_URL`.
+
+Advice is removed from this split once the document it produces is published to the ATO Legal Database, so it always describes work still in progress.
+
+| Column | Type | Nullable | Description |
+|---|---|---|---|
+| `Issue_Number` | string | No | The ATO's `[NNNN]` issue id, e.g. `4253`. Shared across the products under one issue, and recycled — an issue can have completed and in-progress products at once. |
+| `Issue_Title` | string | No | Issue heading, e.g. `Payday Super`. |
+| `Issue_Marker` | string | Yes | The ATO's own `[new]` / `[updated]` flag on the heading; blank when neither. |
+| `Category` | string | No | Grouping page: `GST`, `Income tax`, `Superannuation`, `International`, `Capital gains tax`, `Excise`, `FBT`, `Administration`, `Not-for-profit sector`, `Trust-specific`. |
+| `Category_Slug` | string | No | URL slug of the grouping page. |
+| `Advice_Sequence` | string | No | 1-based index of this product within its issue. |
+| `Advice_Count` | string | No | Number of products under the issue. |
+| `Advice_Type` | string | Yes | Product being developed, e.g. `Final Goods and Services Tax Ruling`, `Draft Practical Compliance Guideline`, `Addendum to Taxation Ruling`, `Decision impact statement`. Blank for the few issues whose Title block opens with the descriptive title instead. |
+| `Advice_Title` | string | Yes | Descriptive title the finished document will carry. |
+| `Is_Draft_Product` | boolean | No | `True` when the product itself is a draft (as opposed to a final or an addendum). |
+| `Purpose` | string | Yes | Purpose block, paragraphs and list items ` \| `-joined. |
+| `Expected_Completion` | string | Yes | Expected completion, e.g. `July 2026`, `To be advised`. |
+| `Comments` | string | Yes | Consultation status — which draft published when, and whether the comments period is open or closed. |
+| `Contact` | string | Yes | Raw contact block as published. Occasionally empty at the source. |
+| `Contact_Name` | string | Yes | Pipe-separated contact names. Blank where the ATO gives only a shared mailbox. |
+| `Contact_Business_Line` | string | Yes | Pipe-separated ATO business lines, aligned with `Contact_Name`. |
+| `Contact_Phone` | string | Yes | Pipe-separated phone numbers. |
+| `Contact_Email` | string | Yes | Pipe-separated email addresses. |
+| `Referenced_Documents` | string | Yes | Legal Database references named by the product, e.g. `GSTR 2026/D1 \| GSTR 2017/1`. Joins to `Document_Reference` / `PCG_Number` / `Statement_Reference` in the other splits. Usually a document reference; occasionally the ATO's descriptive link label (e.g. `Decision impact statement`), in which case `Referenced_Document_IDs` is the machine-usable value. |
+| `Referenced_Document_IDs` | string | Yes | Matching ATO docids, e.g. `DGS/GSTR2026D1/NAT/ATO/00001`. |
+| `Referenced_Document_URLs` | string | Yes | Matching Legal Database URLs. |
+| `Related_Links` | string | Yes | Non-Legal-Database links (consultation pages, web guidance). |
+| `Development_Status` | string | No | Always `Under development` — published advice is filtered out. |
+| `Page_Last_Updated` | string | Yes | ISO timestamp the grouping page was last modified. |
+| `Source_URL` | string | No | Grouping page URL plus the issue anchor (and `-<n>` for multi-product issues). Primary key. |
+| `Unmatched_Content` | string | Yes | Fallback capture: any block not claimed by the structured fields, ` \| `-joined. Usually empty. |
