The rotation guard's narration reading stops at the bookmark's table, so growth below it is invisible #2746

What happens

scripts/check-memory-rotation.py reads a bookmark's per-cycle narration in narration_blocks(). Its loop abandons the rest of the file at the first markdown table row:

for line in text.splitlines():
    if _is_table_line(line):
        break                       # the table is what the file exists for

The comment's premise is that below the table the file holds rows and no prose. Nothing enforces that, so a cycle that appends its note after the table instead of replacing the one before it moves the growth into the region the reader has already left — and the guard answers 0 faults.

Observed — 2026-11-07, this tree's own bookmark

~/.emrg/evolution/emrg/.emrg/memory/project-memory-rotation-bookmark.md:

• 358 lines, of which 29 runs holding 39,411 characters sat below the table's last row. 26 of those runs open on a cycle id in a code span — exactly the narration shape the reading matches.
• 39 distinct cycle ids appear below the table.
• The guard answered, and exited 0:

structure: 0 cycle section(s) and 1 narration block(s) above the table - the file keeps at most one of each, replaced in place

This is the second time this file grew past a shape its guard could not see. The reading exists because of the first: 43 blocks over 729 lines and 94,482 characters (measured 2026-11-05) while the structure reading answered 0 cycle section(s). The remedy then put the boundary at the table instead of removing it, so the growth resumed on the far side of that line.

Expected

A table row ends a block, not the reading. A cycle's note after the table is a second narration block, and a second block is the fault the file's own rule forbids — "Update in place every cycle — never append a second entry".

The bookmark in this tree has been compacted by moving those 29 runs verbatim into cycle-archive-20260913-state.md, the file's designated append-only home; it now reads 115 lines with one narration block.

What the fix must satisfy

• A note below the table is counted: one note above plus one below answers 2 blocks and exits 1.
• Prose after the table that no cycle id opens stays out of the count. The bookmark states its own rules there, and a reader that counted every paragraph would fault the contract it was asked to read.
• The verdict sentence stops claiming the blocks are "above the table", which is false for half the cases it would then cover.
• The reading is armed in both directions: reverting the boundary to break must redden the new test, and dropping the cycle-id anchor must redden it too — otherwise the test would be measuring the file rather than the boundary.
