Codex independent review found 11 blockers post-cascade. All addressed.
CRITICAL (data-loss / crash):
10. crates/core/src/paths.rs — migrate_legacy_data_dir_inner used
fs::rename which fails with EXDEV when source + target are on
different filesystems (encrypted-home, bind mounts, separate
$XDG_DATA_HOME partition). Combined with the Phase 5 QC fix that
made migration errors fatal, this would crash on first launch
for any user whose data dir spans filesystems. Added
rename_or_copy_tree() that falls back to copy_dir_recursive +
remove_dir_all on CrossesDevices / errno 18 (EXDEV). Symlinks
preserved verbatim. Same fallback applied to magnotia.db ->
lumotia.db inside the dir.
11. Added 4 unit tests: copy_dir_recursive preserves nested
structure, rename_or_copy_tree same-filesystem happy path,
is_cross_device classifies CrossesDevices kind + raw errno 18.

Wyrdnote scales from voice-first dictation today to local-first
semantic PKM workbench tomorrow per the engine architecture spec.
The PKM phase needs a serving stack for embeddings + reranking +
entity extraction; this note bookmarks SIE (Superlinked Inference
Engine, Apache-2.0) as the trigger candidate plus six adjacents
to bake off against when the PKM phase lands.
Deferred because (1) PKM sits post-public-beta and infrastructure
decisions today would generalise poorly to a Q4 2026 selection;
(2) the candidates evolve fast; (3) Wyrdnote's local-first +
single-consumer-GPU constraint rules out a today-style bake-off
without real PKM-shape workload to test against.
Decision dimensions captured for the future evaluator: self-host
footprint, cold-start latency, throughput, quality on a Wyrdnote
eval set, reranker availability, extract/NER capability,
OEM-licensability against AGPL-3.0+dual-licence stack, telemetry
posture. Re-evaluation triggers documented.
