P1452. One inherited posting capability replaces the error box riding a fixed live-tail rank. ErrorNote inherits ChronologicalEntry; it captures the already-received cursor before mounting. The transcript owner keeps the earlier saved range before the note and puts subsequent saved rows after it using the existing pager and viewport-preservation path. No fake Pi row, Core cursor field, second reader or error-specific scroll callback. Saved range claims now keep the active publisher alive when an earlier range reports coverage. Reopening an evicted view restores the whole canonical source, not just the last range. Proof: 23 focused app checks passed in 25.81s, including the new chronological, off-tail-scroll and eviction/return case; source-owner guard closing behind this checkpoint. Reader-crash hotfix is separate PR 1736 (already merged). Installed/user verification follows the paired install. Known separate red encountered: the existing wire queue test asserts holds_input at test_input_failure_draft.py:147; not offered as green evidence.
