Phase A.3 finding: AppPaths::migration_sentinel was added with intent
during the rebrand-architecture phase but never wired to any caller.
Exhaustive grep across crates/ src-tauri/ src/ docs/ surfaces:
- 1 definition (paths.rs)
- 1 architecture-map description that ASSERTS the method is in use
- 0 production callers
- 0 test references
Both boot-time migrations (migrate_legacy_data_dir +
migrate_tauri_app_data_dir_with_paths) are idempotent by construction:
each re-probes the legacy path via Path::exists() on every boot and
short-circuits on the steady state. A sentinel file would optimise the
probe but is not required for correctness; one syscall per legacy
candidate at startup is negligible.
Per the atomiser principle of removing dead surface area rather than
keeping stale promises:
- Delete AppPaths::migration_sentinel entirely
- Update docs/architecture-map/.../core-paths.md to describe the actual
idempotency model (re-probing) rather than the sentinel pattern that
was never implemented
- Steer future migrations toward storage/src/migrations.rs schema_version
(transactional, survives backup/restore) rather than reintroducing
filesystem sentinels
Verification:
- cargo test -p lumotia-core paths::: 17/17 (no test relied on the method)
- cargo clippy -p lumotia-core --all-targets -- -D warnings: clean
Phase A.4 (stray-magnotia string scan): clean. Every magnotia reference
in the tree is legitimate — migration source paths, documentation, or
test fixtures. The rebrand cascade was thorough.
dropped_chunks was incremented on cpal-callback channel-full and
validation requeue overflow but never read by the live session, so
the UI's dropped_audio_ms missed callback-level losses entirely.
Architecture doc had flagged this as a TODO. Also: the 350ms
validation buffer was requeued via try_send into the same 32-slot
channel, silently dropping past the cap on small-buffer audio hosts
(WASAPI exclusive, low-latency ALSA at 256 frames -> ~65 chunks).
Fix: live runtime reads MicrophoneCapture::dropped_chunks() on each
recv_audio tick (LiveSessionRuntime::poll_capture_drops) and converts
the per-chunk-duration delta into the dropped_audio_ms surfaced to
the UI overload status. Per-chunk duration is derived from the most
recent AudioChunk's sample_rate + samples-per-channel so it adapts
to whatever rate cpal is delivering at. Validation requeue moved
from try_send into the bounded channel onto a VecDeque<AudioChunk>
returned alongside the Receiver; ActiveCapture drains the replay
buffer before reading rx in recv_audio, bypassing the 32-slot cap
entirely. Architecture doc updated to remove the TODO and document
the new pre-roll path.

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.

Phase 15.1 final-grep residuals:
- HANDOVER.md "Rebrand note" + Phase 10b row updated to reflect that
the cascade completed 2026/05/13 (15 phases, both repos, QC-gated).
- HANDOVER.md two surviving sed artefacts: "Lumotia -> Lumotia" line
restored to "Magnotia -> Lumotia" historical context;
MAGNOTIA_LLM_TEST_MODEL test gate -> LUMOTIA_LLM_TEST_MODEL.
- src/design-system/ui_kits/index.html: MagnotiaApp React function ->
LumotiaApp (sed boundary missed the no-separator boundary).
- docs/architecture-map/README.md: MAGNOTIA_LLM_TEST_MODEL doc note.
Preserved (audit trail):
- docs/handovers/ — historical handover docs.
- docs/superpowers/plans/2026-05-12-engine-slop-residuals.md and
-area-a-storage-errors-survey.md — describe the slop-pass work
using the names current at the time.
- build/index.html, package-lock.json — regenerate on next build/install.
cargo test --workspace: 339 pass / 0 fail. npm run check: 0 errors.

Commit 52565ea migrated storage to magnotia_storage::Error and flattened
typed storage failures into MagnotiaError::Storage { kind, operation,
detail }. No production code constructs the old
MagnotiaError::StorageError String variant anymore.
Remove the legacy variant so new storage failures cannot regress back to
stringly-typed errors.
Also updates living architecture-map docs that referenced the old
variant (core-error.md variant table, storage-overview.md
SQLITE_BUSY note, storage-crud-profiles.md duplicate-name + default-
profile-rename notes, storage-crud-transcripts.md pre-flight FK check
note) and one stale code comment in crates/storage/src/database.rs's
duplicate-name test. Survey doc + old residuals plan + phase8 historical
plan deliberately left alone — they're audit trail of how the migration
was decided, not living docs.
Pre-existing doc rot flagged but not fixed (Other(String) and
Io(std::io::Error) rows in core-error.md are about variants that
already don't match the actual enum shape — separate doc cleanup pass).
Verification:
- cargo fmt --all -- --check
- cargo check -p magnotia-core
- cargo check -p magnotia-storage
- cargo check --workspace --all-targets
- cargo test -p magnotia-storage — 60 passed, 0 failed
- cargo test --workspace --lib — all green
- rg 'StorageError\(' crates/ src-tauri/src/ — zero hits
- rg 'StorageError' crates/ src-tauri/src/ docs/architecture-map/ — zero
- rg 'Other\(String\)' crates/ src-tauri/src/ — zero

The 2026-05-12 engine-slop pass removed runtime std::env::set_var mutation from src-tauri/src/lib.rs and replaced it with warn_if_x11_env_unset_on_wayland. With no launcher owning the contract, Linux Wayland dogfood was about to regress.
run.sh:
- now owns Linux launcher env defaults via case "$(uname -s)"
LIBCLANG_PATH=/usr/lib64/llvm21/lib64 (user-set wins)
WEBKIT_DISABLE_DMABUF_RENDERER=1 (always on Linux; user-set wins)
GDK_BACKEND=x11, WINIT_UNIX_BACKEND=x11 (Wayland only; user-set wins)
- 60s Vite readiness timeout
- detects early Vite exit (kill -0 + wait) instead of hanging forever
- trap installed before wait so Ctrl-C cleans up
- args forwarded: ./run.sh --release etc.
- non-exec final Tauri launch preserved so cleanup trap fires
package.json:
- "dev:tauri": "./run.sh" — canonical discoverable dev command
Docs:
- README, dev-setup, architecture-map runtime + launcher pages updated with the new contract; canonical command is npm run dev:tauri (./run.sh as direct equivalent)
- dev-launcher-and-scripts.md replaces the incorrect "kills process group" claim with honest "kills the spawned npm process"
- dev-setup.md path /CORBEL-Projects/magnotia → /CORBEL-Projects/transcription-app
- gpu-tuning/plan.md gets a superseded note rather than rewriting the original rationale
- engine-slop-residuals.md gains Area F (packaged-binary launcher contract) with honest wrapper-vs-.desktop trade-off documented
Verification: bash -n run.sh; shellcheck clean; cargo check -p magnotia green; npm pkg get 'scripts.dev:tauri' returns "./run.sh"; stale-ref sweep clean across living docs.
