+Keep `markitect-tool` focused on provider-neutral markdown primitives:
+parse, validate, transform, compose, query, template, generate, configure,
+cache, and expose through CLI/API.
+
+Leave infospace lifecycle, persistence/orchestration, project-specific
+knowledge models, rendering applications, and service infrastructure to
+higher-layer repositories.

+1. Read `INTENT.md`, the PRD, the FRS, and active workplans.
+2. Check State Hub for dispatch and blockers when available.
+3. Treat workplan files as authoritative coordination state.
+4. Record durable decisions in repository docs before reflecting them in State Hub.
+5. Keep the implementation boundary narrow: syntax-layer toolkit, not platform.

+Use IDs with the `MKTT-WP-` prefix for this repository. Embedded tasks use
+`MKTT-WP-XXXX-TNNN`.

+Each workplan should trace back to the PRD/FRS and indicate what is migrated,
+reimplemented, deferred, or explicitly out of scope.
