Building-block register — who owes what#
One row per requested contribution. The v0.5 deadline of 26 September 2026 passed without contributions. Every block is now drafted and awaiting its owner's review; see Open questions for partners. Status: OPEN → DRAFTED (drafted, awaiting owner) → REVIEWED (WP4 lead) → APPROVED (TIPS).

By block (status board)#
Every block has a guiding-questions page carrying the iSHARE Template's own questions (386 in total) across 125 LDT answer slots.
All 125 slots now carry a drafted answer, prepared on 8 October 2026 after the v0.5 deadline passed with no contributions, so that the 17 October v0.9 review has text to work from. DRAFTED here means drafted for TIPS to confirm, correct or reject — it does not mean agreed. Every answer is tagged with its provenance: Decided (already fixed by the Grant or Consortium Agreement), Proposed (a defensible default, not an agreed position), or Needs owner (cannot be answered without the named partner).
The 119 Needs owner items are collected in Open questions for partners, grouped by partner. That is the list to work from — reviewing a draft is faster than writing one, which is the point of having drafted them.
See CONTRIBUTING for how to answer, and Template parity for how the fork maps onto upstream.

⚠️ G2 date conflict, for TIPS to settle. This table says 26 Sep; the 🧩 block on Organisational form & governance authority says 17 Oct 2026 (v0.9 review). Both dates predate this fork. Confirm one at the 9 September TIPS and make the other match.
🗓️ PD4 path: 9 Sep TIPS (owners confirmed) → 26 Sep v0.5 blocks in → 3 Oct integrated draft + legal review → 17 Oct v0.9 review → 27 Oct TIPS approval → 30 Oct submission.
