2026-05-26 19:47 UTC. ~94 min wall. 3,468,226 globally-unique docs +
6,235,588 chunks + 90,592,990 edges + 3,468,403 audit events re-routed
from non-deterministic spray-by-ingest-order layout to canonical
content-hash M=4 layout (shard_idx = int(document_root[:8], 16) % 4).
Final state:
per-shard doc uniformity within ±0.04% (theoretical max ±0.05% for
first-32-bit SHA-256 prefix)
audit chain consolidated to shard 000 via Option A (re-sorted by ts,
re-chained; bodies preserved unchanged; tail event type=reshard
carries plan+result body, hash 8da3aa19…)
on-disk sizes: 000=11.0 / 001=8.8 / 002=8.8 / 003=8.8 GB
validation: chunks delta 176 (0.003%) + edges delta 547 (0.0006%)
are cross-shard dupes from re-ingest history, collapsed by
INSERT OR IGNORE; within the 1% tolerance gate
smoke queries: Barack Obama / YouTube / Albert Einstein all
returned proper evidence from correct (hash-routed) shards
chain-check-shards: 0 breaks on every shard
Two mid-flight defect fixes (also committed):
04edff7: derivations.src_root FK guard fired on legitimately
cross-shard refs → writer connection PRAGMA foreign_keys = OFF
c86d5ac: WAL accumulated ~37 GB across passes (SQLite auto-checkpoint
blocked by open reader cursors) → _checkpoint_truncate between
phases. Production migration was rescued mid-flight by manual
sibling-connection wal_checkpoint(TRUNCATE) freeing 27.7 GB.
Closes#000065 in both the index and the per-ticket file. The
per-ticket design doc stays open as a design-log artifact (its
content is still the right reference for the next reshard / for
graft mode #000066).
Follow-on tracked as tasks #44–#47:
#44 re-pack post-reshard shards into DO Spaces (current bucket
packs are stale, still in pre-reshard topology)
#45 verify bucket pack hydration is deterministic against the new
content-hash layout
#46 genesis a fresh peer on 3090-ai.foxhop.net from cloud — first
real SPV-wallet end-to-end test
#47 retire stale pre-reshard bucket packs after #46 confirms
