docs(IMP-19): zone ratio reference + cross-link -- documented-axis close
Stage 5 commit for IMP-19 (gitea #19) — docs-only, no runtime surface.
- new: docs/architecture/IMP-19-ZONE-RATIO-REFERENCE.md (header + A1 consumer
+ A2 producer + A3 Phase Z solver delta + A4 IMP-09 boundary + A5
re-activation gate / GR1-GR4).
- update: PHASE-Z-IMPLEMENTATION-ISSUE-BACKLOG.md — IMP-19 row pending ->
documented + reference doc link; IMP-09 row carries soft back-link to the
IMP-19 reference doc.
- update: PHASE-Q-INSIGHT-TO-22STEP-MAP.md §3 I4 row — prepend IMP-19 anchor
+ reference doc link (step/classification preserved).
Guardrails (Stage 1/2 binding contract): src/ untouched, no role-based
["배경","본심"] hardcoding into Phase Z, IMP-09 solver ownership preserved,
soft-link integrity holds. IMP-19 remains dormant until the A5 gate fires.
