Stage 18R registration: re-trace the crowning chain on the corrected instrument; Stage 19 blocked behind it

Re-scoring repairs a broken measurement, not a broken selection: chunk
boundaries, the ctx header sidecar and the dense embeddings are INPUTS
the CRLF fix changes, and the G+ctx composed effect (+0.0158) is smaller
than its own null control (+0.0277). Four tiers registered (deterministic
retrieval, rerank with fallback recorded, replicated grounded confirms,
dense re-embed). Verdicts decided below 0.015 are re-labelled
UNDETERMINED; load-bearing ones are re-tested with replicates. Stop rule:
if Tier C cannot separate G+ctx from plain G, the crowning unwinds and
the hold-out sees the simpler config.

Also amends Stage 19: staged replicates 1 -> 3 -> 5 per Eli, with a
pre-committed escalation rule keyed on spread rather than on the result.
