Major quality pass on top of Phase 2. Five substantive changes plus
cross-cutting touches across audio, hotkey, transcription, and Tauri
command layers.
Transcription quality
- Long-audio chunking in commands/transcription.rs: Parakeet and large
file transcription now chunk-and-recompose with overlap trimming, so
the live-path chunking advantage extends to file-based workflows.
- Stateful live speech gate in commands/live.rs on top of the earlier
duplicate-boundary filtering — distinguishes start-of-speech from
mid-speech and holds state across chunks.
Auto-learning corrections
- New crates/ai-formatting/src/correction_learning.rs: extracts user
text corrections from viewer edits and proposes additions to the
active profile's vocabulary.
- src-tauri/src/commands/profiles.rs bridge for frontend-driven
confirmation of learned terms.
- src/routes/viewer/+page.svelte hooks the learning path into the
segment-edit flow so corrections feed profile_terms without a
separate 'train this profile' UX.
Transcript profile provenance
- Migration v8 (crates/storage/src/migrations.rs) adds profile_id to
transcripts, defaulting to DEFAULT_PROFILE_ID so existing rows stay
valid.
- crates/storage/src/database.rs: TranscriptRow + CRUD carry profile_id.
- src-tauri/src/commands/transcripts.rs: add_transcript accepts and
persists profile_id.
- DictationPage.svelte + FilesPage.svelte send activeProfileId on
capture so learned corrections are attributed to the right profile.
Cleanup prompt contract
- crates/ai-formatting/src/llm_client.rs hardened: the CLEANUP_PROMPT
now specifies concrete do/do-not rules, ready for a real model-backed
cleanup pass. The llm_client is still a stub — kon-llm remains unwired
— but the prompt shape is final.
Cross-cutting polish
- Minor touches in audio (capture/decode/resample), hotkey (lib/linux/stub),
core, transcription (concurrency/model_manager/local_engine/whisper_rs),
and the rest of src-tauri/src/commands/*: error-path tightening, log
clarity, TS-migration follow-ups (@ts-nocheck additions for incremental
typing).
Verified locally: npm run check, cargo test -p kon-ai-formatting,
cargo test -p kon-storage, cargo test -p kon --lib commands::live::tests,
cargo check — all green.
Scope boundary: kon-llm crate is still a stub; task extraction remains
rule-based. Bundled local-LLM runtime is the next clean step and is not
in this commit.

crates/storage/src/migrations.rs:
Replace naive sql.split(';') with split_statements() that tracks
BEGIN...END depth, so migrations containing trigger definitions
execute correctly instead of being split mid-block.
crates/transcription/src/lib.rs:
Re-export transcribe_rs::SpeechModel so callers in src-tauri can
reference it without adding transcribe-rs as a direct dependency.
src-tauri/src/commands/models.rs:
Use Box<dyn SpeechModel + Send> as the load_model_from_disk return
type, matching the trait object that transcription crates produce.
src-tauri/src/commands/transcripts.rs:
Remove the stale .map(|v| v as i32) casts on sample_rate and
audio_channels. InsertTranscriptParams now stores these as i64
(ebf449b), matching the i64 fields on CreateTranscriptRequest;
casting to i32 first would silently truncate large sample rates.

Finally exposes the canonical SQLite store to the frontend. Previously
the transcript/task tables existed but no Tauri command read or wrote
them — the UI lived entirely in localStorage. Closes that gap and adds
the missing commands flagged by both Codex and architecture-review.md
§13.
MIGRATIONS:
- v2 adds:
- transcripts_fts virtual table (FTS5, porter+unicode61 tokeniser,
diacritics-folded) backed by transcripts via content_rowid
- INSERT/UPDATE/DELETE triggers keep FTS in sync automatically
- dictionary table for custom vocabulary (term, note, created_at)
- Append-only as required; never modifies v1
STORAGE FUNCTIONS (crates/storage/src/database.rs):
- list_transcripts_paged(limit, offset) — pagination
- count_transcripts() — for "showing X of N" in UI
- update_transcript(id, text?, title?) — closes the historic
architecture-review.md §13 rename-never-persists TODO
- search_transcripts(query, limit) — FTS5 wrapper
- list_dictionary / add_dictionary_entry / delete_dictionary_entry
- DictionaryEntry struct exported
TAURI COMMANDS (src-tauri/src/commands/transcripts.rs new file):
- add_transcript, list_transcripts, count_transcripts_command,
get_transcript, update_transcript, delete_transcript,
search_transcripts
- list_dictionary_command, add_dictionary_entry_command,
delete_dictionary_entry_command
- TranscriptDto + DictionaryDto for camelCase frontend serialisation
REGISTRATION (src-tauri/src/lib.rs):
- All 10 new commands wired into the invoke_handler
cargo check -p kon-storage passes clean. The Tauri crate cargo check
still requires `sudo dnf install cmake clang-devel` for whisper-rs-sys
(pre-existing infra dep, unrelated to this work).
NEXT (still in this sprint):
- Wire DictationPage / FilesPage to call add_transcript on every save
(dual-write: keep localStorage for now, add SQLite alongside)
- Wire HistoryPage rename to call update_transcript (fixes the TODO)
- Add a History search input that calls search_transcripts
- Add Settings → Dictionary panel
- Inject dictionary terms into the LLM cleanup prompt
