Summary

P3D4B = DOT package design review only. No PG mutation, no Directus mutation, no permission change, no executable artifact, no Nuxt, no Codex dispatch.

• Đ43 (System Context Law) does not govern notification view/DOT — no jurisdiction overlap, no schema repair required.
• Existing DOT conventions reused: 3-part description contract (Description Governance R2 / Fix 27) + NT12 paired-DOT pattern + PG-Native counting via COUNT(DISTINCT actor_ref).
• Candidate view v_iu_notification_board: scope HISTORY, payload OMIT_RAW_PAYLOAD, metadata-only, body-free.
• Candidate DOT pair DOT-NOTIF-BOARD-EXPOSE ↔ DOT-NOTIF-BOARD-EXPOSE-VERIFY (NT12).
• Role: NEW_ROLE_RECOMMENDED — notif_board_reader (no analogous role found in upstream inventory).
• Overlap risk LOW. Gate GO.

Inventory steps

1. Read mandatory laws (constitution Đ7/Đ35/Đ43, Đ7 Assembly First, data-connection law) and P3D context (P3D UI boundary note, P3D3 design, P3D4 review, P3D4 review report). Done via batched read.
2. Bounded KB search for Đ43/DOT/counter/relationship/template artefacts. Found: du-thao-description-governance-package-fix27.md (3-part DOT description contract), dot_tools registry columns, NT12 pairing pattern.
3. Confirmed (from upstream P3D4 inventory) that no %notif% view exists yet, both base tables already auto-registered as Directus collections, no notification grants in place.
4. Drafted non-executable PG view sketch + DOT outline + payload/role/scope decisions.
5. Authored package review note.
6. Authored this report.

No tool/MCP mutation performed.

Notes for P3D4C author

• Lock the LATERAL syntax + tie-break ordering (read_at DESC, actor_ref ASC) before CREATE VIEW.
• Re-confirm role inventory at execution time — if a generic board_reader already exists, prefer reuse; otherwise create notif_board_reader scoped to view only.
• Carry the 24–48h quiet period clause before stacking the mark-read package.
• Rollback: REVOKE SELECT ... ; DROP VIEW IF EXISTS v_iu_notification_board; — DOT-driven, paired-verifier asserts.
• Do not join information_unit.body or unit_version.body. Do not include raw payload jsonb.
