Sprint B — closes audit item B7 (doc consolidation).
- docs/AGENT_TASK_ROADMAP.md, docs/ARCHITECTURE_REVIEW_AND_REUSE_ROADMAP.md,
docs/GAP_ANALYSIS.md were each self-marked as historical snapshots
but kept polluting the top of docs/. Moved them under docs/archive/
in the previous commit; this commit:
- Adds docs/archive/README.md explaining what's archived vs active
- Repoints cross-doc links in docs/IMPLEMENTATION_TRACKER.md,
docs/WEB_AI_FAST_ROADMAP.md, and docs/roadmaps/*.md to the new
archive paths
- Fixes relative links inside the archived files themselves so
historical readers can still navigate back to active docs
- AGENTS.md §1.1 refreshed: reflects the May 22 re-verified state
(382/96/97 tests), links the two new runbooks, and points readers
away from docs/archive/ as a work source.
