Summary

• updates project status from completed Phase 2 to Phase 3 in progress
• documents named parameters, live ctl, per-note values, and ramp
• adds nREPL startup, discovery, safety, and editor-facing overview
• documents current control/automation trace flags and nREPL CLI flags
• links every top-level guide under docs/, grouped into user and architecture sections
• removes obsolete limitations claiming controls, automation, and nREPL are unavailable
• keeps remaining Phase 3 gaps (buses, MIDI, transitions) explicit

Validation

• verified every docs/... link in README.md resolves to an existing file
• git diff --check

Correction to local validation output: the README contains 17 docs/... links covering 12 unique existing files; all resolve successfully. The earlier printed count used an incorrectly escaped reporting regex, while the actual missing-link check used the correct regex and passed.
