Confirmed understanding

• Current state: P3D4B PASS, go_nogo_gate=GO, next required pack is P3D4C_PG_VIEW_AND_DIRECTUS_DOT_IMPLEMENTATION_PROMPT_REVIEW.
• P3D4C next action is to draft an implementation prompt only; do not dispatch execution yet.
• No PG mutation, no Directus mutation, no Nuxt code, no Hermes start during P3D4C prompt drafting.
• Future implementation target is public.v_iu_notification_board with view_scope=HISTORY.
• View must be metadata/ref-only: event metadata, canonical address, refs, actor/source/timestamps, read_count, latest_readers.
• View must not expose IU body, unit_version body, raw payload jsonb, secrets, or sensitive content.
• read_count must use PG-native COUNT(DISTINCT actor_ref) from iu_notification_read; no separate counter table.
• latest_readers must be deterministic: top 5 by read_at DESC, actor_ref ASC.
• Directus exposure must be DOT/change-package driven, read-only, and preferably view-only.
• Candidate DOT pair remains DOT-NOTIF-BOARD-EXPOSE and DOT-NOTIF-BOARD-EXPOSE-VERIFY, using 3-part description contract and NT12 paired-DOT convention.
• Role strategy: re-check/reuse suitable existing read-only role at execution time; otherwise use notif_board_reader only within approved P3D4C prompt scope.
• Human mark-read, Directus user-to-actor mapping, Nuxt display assembly, and Hermes production remain deferred.
• Điều 43/DOT overlap risk was assessed LOW in P3D4B; do not repair Điều 43 schema blockers or duplicate DOT/counting conventions in Pack 23/P3D4C.
• Directus/Nuxt/PG boundary remains hard: PG is source of truth/runtime; Directus is DOT-driven exposure/view layer; Nuxt is display assembly only and must not read PG directly or hold business logic.

Next allowed action

Instruct Opus/Claude to create:

knowledge/dev/laws/dieu44-trien-khai/prompts/23-p3d4c-pg-view-directus-dot-notification-readonly-implementation-prompt.md

with later execution report path:

Do not dispatch implementation until GPT/User review and approval.
