## role
Contains archived specification documents for a deprecated layered map protocol that introduced paired navigation artifacts to replace bulk-loading of map files with a tiered directory-level routing system.
## files
- apply-progress.md | Documents the completion status and summary of implemented features for an "Apply Progress" project or milestone.
- archive-report.md | Documents the archival status and metadata for a deprecated layered map protocol specification directory.
- design.md | Design document for a paired navigation-first artifact model that generates both routing indexes and orientation rich-maps from a shared intermediate directory model while preserving existing pipeline behavior. | dep: spec.md, src/format.ts, src/init.ts, src/patch.ts, src/validate.ts, pi-extension.ts, README.md, SKILL.md, design-doc.md, CLI argument parsing, YAML config handling
- proposal.md | Proposes a layered navigation protocol using paired index/map artifacts to replace bulk-loading of map files with a tiered, directory-level routing system.
- spec.md | Specifies a layered navigation protocol for project maps using paired index and rich map artifacts per directory with defined generation, patching, and validation behaviors.
- sync-report.md | Documents that a canonical spec synchronization was not performed due to legacy flat change artifact structure, with user-approved archival fallback
- tasks.md | Defines a phased task plan for implementing a layered paired-map protocol with directory-level `.pi-map.md` and `.pi-map.index.md` artifacts, routing metadata, patch sizing, validation, and documentation. | dep: design.md, pi-extension.ts, SKILL.md, README.md, design-doc.md, npm/node toolchain
- verify-report.md | Documents verification results for a code change implementing a layered map protocol with paired artifacts. | dep: npm, vitest, node, typescript
## arch
Document-driven specification archive using a layered architecture with paired index/map artifacts per directory, phased implementation tasks, and formal verification/synchronization reporting, preserved for historical reference despite legacy flat structure preventing canonical sync.
