 - [x] Archive the unreferenced five-file monorepo-consolidation planning bundle byte-identically with explicit historical boundaries.

 ## Initial findings

 - The #756 Discord code-review, security-review, and documentation-checklist reports had no source/test consumers and moved byte-identically to their canonical report categories. `docs/reports/README.md` labels their historical evidence boundary.
 - Independent safety review found that Discord external route strings are not proven to map to UUID conversation rows. Current pages now promise live routing/delivery only, disclose that persistence can fail while dispatch continues, and require pre-enrollment for privileged durable-session controls.
 - The monorepo-consolidation brief, board review, and three work-package specifications had no live consumers or internal links. They moved byte-identically to `archive/planning/`; current package existence supports historical classification but does not prove every old acceptance criterion.
+- Ten additional unreferenced implementation plans, setup records, and deferred stubs moved byte-identically to `archive/planning/legacy/`. `agent-reflection-loop-PRD.md` was excluded because a MACP test names its intended canonical path; the WebUI/Fleet bridge draft was excluded because it remains authority-gated.
