# Alexanarch audit complete-thread chronology through #1–#18

- Frozen corpus boundary: #1–#1426 at commit `055429ac82edc967f09c4640ffd0b049cff78e6e`.
- Governing inherited handoff: #359–#1426 (1,068 records).
- Current-thread audit: #1–#358 (358 records) in 17 ordinary 20-record checkpoints plus terminal checkpoint #1–#18.
- Final contiguous audited range: #1–#1426 (1,426 records; 100.00%).
- Terminal fallback unit: #1–#38, closed after #19–#38 and #1–#18.
- Remaining audit checkpoints: none.
- Repository repairs: none.
- Required next controlled pass: lifecycle conversion for #1–#498.

The final cumulative handoff is the recovery point for the completed frozen-corpus audit. Nested checkpoint ZIPs remain immutable and authoritative.
