Do not re-litigate these; they are checked facts. + +| Aspect | Finding | +|---|---| +| Dart binding source | **Zero `.dart` files changed** between `v2.14.0..v2.17.0`. Only `bindings/dart/dart/pubspec.yaml` version bump + vendored `bindings/dart/native/decentdb.h` refresh. | +| C ABI version | `DDB_ABI_VERSION` is **7 in both** versions. Header changes are purely additive. | +| On-disk format | `DB_FORMAT_VERSION` **13 → 14** (`crates/decentdb/src/storage/header.rs`). | +| Format enforcement | `header.rs:80` is a **strict inequality reject** → `DbError::unsupported_format_version`. No backward read compat, no forward compat. | +| Engine error text | `"unsupported database format version: {version}"` — our `DecentDbMigrationService.isUnsupportedFormatVersionMessage()` already matches this substring. No change needed. | +| Migration path | `decentdb-migrate` `migrate_v13_file()` = header version patch + WAL sidecar carry-forward. Out-of-place (source→dest), non-destructive. Does **not** reject an existing source WAL (unlike formats 3/8/9). Rejects if the **destination** `.wal` already exists. | +| Release assets | `v2.17.0` publishes all shapes our resolver expects (`decentdb-v2.17.0-*`, `decentdb-dart-native-v2.17.0-*`), and `decentdb-migrate` is bundled in the main archive (`.github/workflows/release.yml:315`). Asset resolution is dynamic from GitHub release metadata keyed on the `pubspec.lock` tag, so no hardcoded names to update. | + +Two corrections to prior assumptions in this repo: + +1. **`_sysInspectionPreparedBoundaryView` in `decentdb_bridge.dart` is stale dead code.** Its + message still cites "DecentDB v2.8". The engine's `try_execute_prepared_inspection_query` + exists in v2.14.0 too, and `decentdb_bridge_smoke_test.dart:1201` already asserts all 17 + `sys.*` views return `available: true`. Delete the placeholder and the + `_isSysSchemaBoundaryError` short-circuit `break`. +2. **Runtime tracing is unreachable from Dart.** `RuntimeTracingConfig::enabled` defaults to + `false` and there is **no C ABI open option** to enable it (see the documented option-key + list in `include/decentdb.h`; `DbConfig::tracing` is Rust-embedder-only). `sys.slow_queries`, + `sys.lock_waits`, `sys.index_usage`, `sys.sessions` are SQL-parseable and return a valid + **empty** result, not an error. Do **not** add them as diagnostics panels — they would be + permanently empty and misleading. This is also why the Doctor panel is CLI-backed. + +`sys.*` views are matched by **exact normalized SQL text** in +`crates/decentdb/src/db/sync_api.rs`. Queries must be exactly `SELECT * FROM sys.` with +no appended `LIMIT` or extra clauses, or interception silently fails. The existing +`_operationalMetricQueries` entries already follow this; row capping is applied client-side. + +## Decisions taken + +- **Format migration UX:** guided **in-place upgrade with backup**. Preserve the user's original + filename so recent-files and workspace-project references keep working. +- **Doctor panel:** **CLI shell-out primary** (`decentdb doctor --format json`), in-process + `sys.doctor_findings` / `sys.fix_plan` as fallback when the CLI cannot be resolved. +- **Adoption scope:** all of Tier 1, Doctor panel, EXPLAIN cost/cardinality + ANALYZE, + full-text search awareness, import typed-batch/UUID fast path, index maintenance actions. + +## ADRs required (next free number is 0060) + +- **ADR-0060** — DecentDB v2.17.0 upgrade and the format-14 guided in-place migration contract + (backup naming, swap ordering, sidecar handling, failure/rollback, one-way downgrade warning). +- **ADR-0061** — Doctor/advisor diagnostics boundary: CLI-backed primary with `sys.*` fallback, + and the explicit rationale that runtime tracing is not reachable through the Dart binding. +- **ADR-0062** — Database performance profile and plan-cache open options exposed in Preferences. + +Also update **ADR-0003** (pinned SQL capability baseline) and **ADR-0025** (git dependency +rationale) for the new tag, and **ADR-0058** if schema-snapshot parity assertions shift. + +--- + +## Task list + +### Phase 1 — Dependency bump and baseline green + +1. In `apps/decent-bench/pubspec.yaml:16`, change `ref: v2.14.0` → `ref: v2.17.0`. + Run `flutter pub get` and confirm `pubspec.lock` records `v2.17.0` / `version: "2.17.0"`. +2. Delete the cached native asset tree (`apps/decent-bench/.dart_tool/decentdb/`) so + `DecentDbNativeReleaseAsset` re-downloads for the new tag. Confirm the library, `decentdb` + CLI, and `decentdb-migrate` all resolve. +3. Update the hardcoded `2.14.0` expectations in tests: + - `test/widget_test.dart:502,569` + - `test/support/fakes.dart:360` + - `test/features/workspace/infrastructure/decentdb_bridge_smoke_test.dart:1345,1376,1398` + - `test/features/workspace/domain/workspace_metadata_contract_test.dart:9` + - `test/features/workspace/domain/sdk_generation_test.dart:88,231` + - `test/features/workspace/domain/query_phase_models_test.dart:6` + - `test/app/logging/app_logger_test.dart:47,58` + Prefer introducing a single shared constant (e.g. `expectedDecentDbVersion`) in + `test/support/` and referencing it, so the next bump touches one line. +4. Run `flutter analyze` and `flutter test`. Baseline before this work is **658 passing, 1 + analyzer info**. Fix the pre-existing dangling-doc-comment info at + `lib/features/export/infrastructure/parquet_exporter.dart:1:1` while here. +5. Fix stale version drift in docs (currently still claiming v2.8.x): `README.md:22,67,70,74,97,189`, + `apps/decent-bench/README.md:26,46,51,54,81`, `design/VERSIONING_GUIDE.md:74,159`, + `THIRD_PARTY_NOTICES.md:10`. + +### Phase 2 — Format-14 guided in-place migration (highest risk; do before any feature work) + +6. Extend `DecentDbMigrationService` (`lib/features/workspace/infrastructure/decentdb_migration_service.dart`) + with a guided in-place mode. Current `migrate()` deliberately rejects + `source == destination` (line 122) and a pre-existing destination (line 137) — keep that + method unchanged and add a new `migrateInPlace()` that orchestrates: + 1. Verify no other handle is open on the path; close the workspace database first. + 2. Migrate to a temp destination **in the same directory** (same filesystem, so the final + move is atomic). + 3. Move the original to `.ddb.v13.bak` (never delete it). + 4. Move the migrated temp file into the original path. + 5. On any failure, restore the original from the backup and leave no partial file. +7. Handle the sidecar file set explicitly. Per the DecentDB mobile/backup contract the + authoritative set is ``, `.wal`, `.sync-journal`, `.coord`. Requirements: + - `decentdb-migrate` refuses to run if the **destination** `.wal` exists → ensure the temp + destination is clean. + - `migrate_v13_file` carries the source `.wal` forward, so the source WAL must **not** be + deleted or pre-checkpointed by us. + - `.coord` is a rebuildable sidecar and must **not** be carried to the new file; let the + engine recreate it. + - Back up any sidecars alongside the `.v13.bak` original. +8. Wire detection into the open path. `DecentDbBridge._handleOpenDatabase` calls + `Database.open(...)` (open-or-create). For an existing format-13 file this throws with the + matched message. Route that through the existing `DecentDbMigrationFailure` / + `decentdb_migration_dialog.dart` flow so the user gets: detected old format → explain → + offer guided upgrade → show backup path → warn that **downgrade is impossible** and older + Decent Bench builds will not open the upgraded file. +9. Run the migration subprocess off the UI thread and show determinate-enough progress; large + files are a byte-for-byte copy. Support cancellation before the swap step. +10. Apply the same detection to the headless entry points so batch users get an actionable + error naming the exact `decentdb-migrate` invocation: + `lib/app/headless_import_runner.dart`, `lib/app/headless_quality_runner.dart`, + `bin/headless_import.dart`, `bin/dbench_quality.dart`. +11. Tests: unit-test `migrateInPlace()` with a fake process runner for success, tool-missing, + non-zero exit, destination-WAL-present, and mid-swap failure (assert original is restored + and the `.v13.bak` is intact). Add a real format-13 fixture to `test-data/` and an + end-to-end migration test gated on native-library availability, mirroring the existing + smoke-test skip guard. + +### Phase 3 — Tier 1 free wins + +12. In `decentdb_bridge.dart`, **delete** `_sysInspectionPreparedBoundaryView`, + `_isSysSchemaBoundaryError`, and the `break` short-circuit in + `_handleLoadOperationalMetrics` (~line 1091). Per-view `available` / `error` handling + already degrades gracefully. +13. Add to `_operationalMetricQueries` (~line 1750), exact SQL text only, no `LIMIT`: + `sys.plan_cache`, `sys.plan_cache_summary`, `sys.doctor_findings`, `sys.fix_plan`, + `sys.sync_shapes`, `sys.sync_shape_clients`, `sys.sync_changeset_history`, + `sys.sync_relay_sessions`. Extend the smoke-test view-name list accordingly. + **Do not add** `sys.slow_queries`, `sys.lock_waits`, `sys.index_usage`, `sys.sessions`. +14. Expose the new `profile` open option (v2.15). Accepted values, parsed in + `crates/decentdb/src/c_api.rs:1470`: `default`, `low_memory`, `balanced`, `embedded_fast`, + `tuned_durable`. Critical ordering constraint: `profile` **resets** the whole config, and + other keys applied afterward override it — so emit `profile=` **first** in the options + string. Unknown values are a hard error, so validate in the UI. +15. Expose `plan_cache_enabled` and `plan_cache_max_bytes` open options, and add a + "Flush plan cache" action running `PRAGMA flush_plan_cache`. +16. Thread both through `AppConfig` / TOML config and `preferences_dialog.dart` alongside the + existing write-queue settings. Build them into the single options string in + `_handleOpenDatabase` (~line 1008), extending the `_writeQueueOpenOptionsFromPayload` + helper into a general open-options builder. Add round-trip config-store tests. + +### Phase 4 — Doctor / advisor panel (ADR-0061) + +17. Add `DecentDbDoctorService`, modeled directly on the existing + `decentdb_lua_extension_validation_service.dart` (same `DecentDbCliResolver` + + `Process.run` + JSON-parse shape). Invoke: + `decentdb doctor --db --format json --checks all --include-recommendations=true`, + plus `--verify-indexes` / `--verify-index ` and `--max-index-verify` when the user + requests index verification. Note `--fail-on` defaults to `error`, so a non-zero exit is + an expected outcome for an unhealthy database, **not** a tool failure — parse the JSON + payload regardless of exit code. +18. Model the 8 check categories (`header`, `storage`, `wal`, `fragmentation`, `schema`, + `statistics`, `indexes`, `compatibility`) with severity and recommendations. Let the user + select a subset via `--checks`. +19. Fall back to the in-process `sys.doctor_findings` / `sys.fix_plan` views (already added in + task 13) when the CLI cannot be resolved, and label the panel clearly so a degraded result + is not mistaken for a clean bill of health. +20. Present in a Doctor panel reachable from the menu/command palette, registered in + `menu_command_registry.dart`. Run off the UI thread. Note there is an existing + `app_menu_command_audit_test.dart` contract that new commands must satisfy. + +### Phase 5 — EXPLAIN cost/cardinality and ANALYZE + +21. `workspace_controller.dart:4611` already runs `'EXPLAIN $sql'`. v2.13+ adds estimated rows + and relative cost, plus explicit `HashJoin`, `IndexedJoin`, `StreamingAggregate`, + `ViewScan`, and `ExpandedView` plan nodes, and v2.15 surfaces expanded-view pushdown + metadata. Extend the parser in `domain/explain_plan_visualization.dart` and its renderer to + display estimated rows/cost and the new operator kinds. +22. Add an ANALYZE action so `EXPLAIN` can use persisted statistics. Surface whether stats are + present/stale, since plan quality depends on it. +23. Update `explain_plan_visualization_test.dart` with real captured v2.17.0 `EXPLAIN` output + for each new node kind. Keep the parser tolerant of unknown node kinds so a future engine + bump degrades rather than throws. + +### Phase 6 — Full-text search awareness + +24. `IndexKind` in the engine is `Btree | FullText | Spatial | Trigram`, and the Dart + `SchemaIndexInfo` carries `kind`. Surface non-Btree index kinds distinctly in the schema + browser (`shell/schema_explorer_pane.dart`, `shell/schema_browser_models.dart`) instead of + flattening everything to a generic index. +25. Add `fulltext_match`, `bm25`, and the `USING fulltext` DDL form to + `domain/sql_vocabulary.dart` and the autocomplete/formatter paths + (`sql_autocomplete.dart`, `sql_formatter.dart`, which already list `ANALYZE`). +26. Add `ALTER INDEX VERIFY` / `REBUILD` as schema-browser maintenance commands. + Treat these as writes and route them through the existing risk-assessment path + (`sql_risk_assessment.dart`). + +### Phase 7 — Import fast path + +27. Adopt `Statement.executeBatchTyped(signature, rows)` in the import pipeline + (`import_execution_service.dart`, `excel_import_support.dart`, `sql_dump_import_support.dart`, + `sqlite_import_support.dart`), replacing per-row bind/execute loops. `executeBatchTyped` is + currently unused anywhere in the app. + Signature chars per the refreshed header: **`i`=INT64, `b`=BOOLEAN, `f`=FLOAT64, `t`=TEXT**. + `b` is new in v2.16 and shares the `values_i64` array using 0/non-zero. +28. Columns outside `i`/`b`/`f`/`t` (BLOB, DECIMAL, TIMESTAMP, UUID, …) are not expressible in a + typed batch — keep the existing `bindAll` path for those and select per-table at plan time. + Wrap batches in an explicit transaction, as the upstream Dart docs show. +29. Bind UUID columns via `UuidValue` (v2.15 added UUID handling for prepared statements and + runtime indexes). Today the code only string-matches the `'UUID'` type name in + `native_type_models.dart` and the import supports. +30. Add a round-trip import test per changed importer and re-run the existing + `import_fixture_round_trip_test.dart` fixture matrix. Record a before/after throughput note + for a large fixture to confirm the win is real. + +### Phase 8 — Index maintenance and cleanup + +31. Expose `save_as` (compact copy) and `evictSharedWal` as maintenance actions — + `Database.evictSharedWal(path)` must only be called after **all** handles for that path are + closed, so gate it behind a full workspace close. +32. Update `design/adr/0003` and `0025` for the new tag, write ADR-0060/0061/0062, and update + `CHANGELOG.md`, `README.md`, and `apps/decent-bench/README.md`. +33. Consider extracting a `WorkspaceController` sub-controller for the new diagnostics/doctor + surface rather than growing the existing 5,531-line file + (`lib/features/workspace/application/workspace_controller.dart`), following the established + `BranchController` / `DataQualityController` pattern. + +--- + +## Validation + +Run from `apps/decent-bench/`: + +``` +flutter analyze +flutter test +flutter test integration_test +``` + +Baseline to preserve or beat: **658 tests passing, 0 analyzer warnings/errors** +(the 1 pre-existing info is fixed in task 4). + +Manual verification checklist: + +- Open a **format-13** database created by the current shipped build → guided migration is + offered, completes, original filename is preserved, `.v13.bak` exists and is byte-identical + to the pre-migration original. +- Migration failure mid-swap → original database is intact and openable after restore. +- Open a format-13 file **with an existing `.wal`** → migration still succeeds and committed + data in the WAL survives. +- Open an already-format-14 database → no migration prompt, no spurious dialog. +- Headless CLI against a format-13 file → clear, actionable error naming `decentdb-migrate`. +- Diagnostics panel → the 8 new `sys.*` views populate or degrade cleanly per-view; no + always-empty tracing panels are present. +- Doctor panel with the CLI available → all 8 categories render. With the CLI removed from + PATH/cache → labeled fallback, no crash. +- Switch `profile` in Preferences → reopen → new option string takes effect; an invalid value + is rejected in the UI before reaching the engine. +- Large import (use an existing `test-data/` fixture) → no UI jank, throughput improved, + row-for-row identical results vs. the pre-change importer. + +## Risks + +1. **Format 13 → 14 is one-way and affects every existing user file.** This is the dominant + risk. The backup file is the only recovery path; never delete it automatically. +2. **In-place swap is the sharpest edge.** Keep temp file and final target on the same + filesystem so the final move is atomic, and make failure restore the original + unconditionally. +3. **`.coord` sidecar must not be carried forward** — it is rebuildable and stale coordination + state could confuse cross-process gating. +4. **`sys.*` exact-SQL-text matching** — an appended `LIMIT` or reformatting silently breaks + view interception. Cover each new view in the smoke test. +5. **Doctor's `--fail-on=error` default** means non-zero exit is normal for an unhealthy DB; + treating it as tool failure would break the panel. +6. Engine behavior changes in v2.15–v2.17 (planner now picks `IndexedJoin` for explicit + `JOIN ... ON`; poisoned-lock panics became typed errors; checkpoint durability barrier added) + may shift `EXPLAIN` snapshots and error-path assertions in existing tests.

Killing the isolate is the + only reliable interrupt today.
