Roadmap

Phase	Focus	Why now?	Key deliverables
1. 2025‑Q2 – "Bedrock"	Migrations + CI baseline	We’ve landed versioned migrations and removed runtime column hacks – ensure it stays solid.	• CI job runs cargo test + cargo sqlx migrate run --dry-run
2. 2025‑Q2	Leaner FTS maintenance	Per‑row triggers don’t scale past ~100 k files.	• Replace triggers with “dirty” flag + periodic rebuild • Benchmark on 100 k files
3. 2025‑Q3	Content hashing & dedup	Detect duplicates, enable future integrity checks.	• SHA‑256 in files.hash • scan --rehash option
4. 2025‑Q3	Tag aliases / canonicals	Control tag sprawl before users accumulate thousands.	• canonical_id enforcement • tag alias add/ls/rm CLI
5. 2025‑Q4	Search DSL v2	Power users want grouping, boolean ops, quoted phrases.	• Replace ad‑hoc parser with nom grammar • Unit‑tested examples
6. 2025‑Q4	Attribute templates	Structured metadata unlocks real workflows.	• templates + template_fields tables • Validation on attr set
7. 2026‑Q1	Dolphin read‑only plugin	Browse tags/attrs inside the default file manager.	• Qt sidebar showing metadata
8. 2026‑Q1	Full edit UI	After read‑only proves stable, add editing.	• Tag editor widget, attribute dialog
9. 2026‑Q2	Multi‑device sync	Final frontier: optional sync/replication layer.	• Choose between rqlite / Litestream / bespoke • Read‑only mode for network mounts

Current sprint (ends 2025‑06‑01)

1. FTS rebuild prototype – dirtied‑rows approach, measure on 50 k files.
2. backup --prune to keep only N most recent snapshots.
3. Integration tests for tag/attr workflows on Windows via GitHub Actions.

Development principles

• Local‑first – every feature must work offline.
• Zero manual migrations – shipping code is the migration.
• Instrumentation first – every new command logs trace spans and timings.
