SISS — Silicon Island Submission System¶

The Silicon Island Submission System (SISS) is the digital submission and review platform for planning and building applications to the Silicon Island local authority (CMU). It replaces paper-driven workflows with a single system that accepts submissions, validates parameters, routes work to the right technical agencies with SLAs, uses AI (always human-in-the-loop) to assist compliance checking and comment drafting, and issues digitally signed Kertas Perakuan, SIGL, and Surat Sokongan certificates.

Sources of truth¶

This site is a navigable summary. The authoritative source documents live alongside the repo:

Architecture spec — docs/superpowers/specs/2026-04-13-siss-architecture-design.md
M2 implementation plan — docs/superpowers/plans/2026-04-13-siss-m2-km-digital-backbone.md
Project planning CSVs — docs/SISS - Project Planning V1.0 - *.csv

When this site and the source documents diverge, the source documents win.
