… schema) Three latent gaps surfaced when running `tauri build` against this repo for the first time on 2026-04-25: 1. `crates/desktop/Cargo.toml` was library-only (`[lib] crate-type = ["staticlib", "cdylib", "rlib"]`). `tauri build`'s internal `cargo build --bins` matched zero targets and silently produced no executable. Adding `[[bin]] name = "perima-desktop" path = "src/main.rs"` gives the bundler something to package while keeping the library shape for future mobile/UniFFI shells. 2. `crates/desktop/src/main.rs` did not exist. The new file is a thin `fn main()` that builds a multi-thread tokio runtime, registers it as `tauri::async_runtime`, holds an `EnterGuard` for main's lifetime, then calls `perima_desktop::run()`. Without the explicit runtime entry, `AppContainer::new` panicked with "there is no reactor running" because Tauri 2's setup callback runs on the main thread but does not enter `tauri::async_runtime` into TLS — it expects callers to use `tauri::async_runtime::spawn` directly. Tracked as #146; the architectural fix (explicit Handle parameter on `AppContainer::new`) supersedes this workaround. 3. `crates/desktop/tauri.conf.json` declared `"plugins": { "dialog": {} }`. Tauri 2's `tauri-plugin-dialog` config schema rejects `{}` with `invalid type: map, expected unit`, panicking at startup. Replaced with `"plugins": {}` so the plugin loads with default config. Together these unblock `tauri build --bundles deb` producing a working binary that survives `perima-desktop` launch + window initialisation. The CI smoke-launch issue (#147) would have caught all three earlier.
…esult-set bumps Four user-visible UX fixes that landed together this session, all small and mutually independent. 84/84 frontend tests green after the changes. 1. Tags UI minimum-viable wiring (closes part of #156) `RowTagsCell` per row in `FileTable.tsx`: per-row text input attaches a tag on Enter; chips render the existing `TagChip.onRemove` X button to detach. New `useAttachTag` + `useDetachTag` mutations in `queries/tags.ts` invalidate `filesKeys.all` + `tagsKeys.all` on success. Polish (autocomplete, palette pick, FileGrid parity, optimistic, bulk, rename/merge) tracked in #152. 2. Search auto-prefix in `lib/search.ts::buildFtsQuery` Plain queries now auto-`*`-suffix the last token so users get prefix matching by default. Typing "Cl" produces `"Cl"*` → finds Claude; "mp4" produces `"mp4"*` → finds every mp4. Phrase passthrough (`"foo bar"`) and explicit prefix (`foo*`) unchanged. Tests updated. 3. Search debounce 300 → 180 ms in `SearchBar.tsx` User feedback: 300ms felt sluggish for incremental typing. 180ms still coalesces fast typists (avg keystroke gap ~150-200ms) so we don't issue an IPC per keystroke, but feels "live" on slow typing or paste. Tests use `advance(300)` which still satisfies the new shorter timer. 4. Result-set limit bumps in `routes/index.tsx` + `queries/search.ts` `useFiles(100) → useFiles(1000)` and `useSearch` default limit `50 → 500`. The display path is `useFiles(N) ∩ search_hits`; with N=100 a library larger than 100 files showed only the search hits that happened to be in the first-100 page (e.g. searching "mp4" in a 340-file library returned 3 of 339 actual matches). Bumping to 1000 covers the common case (<1k files) without rearchitecting. Real fix for 10k+ libraries is virtualisation + result-driven pagination, tracked as #150 (priority/low). Test fixes: - `SearchBar.test.tsx`: assertions updated to expect auto-prefixed `*`. - `FileTable.test.tsx`: migrated to `renderWithProviders` (RowTagsCell needs QueryClient context); replaced obsolete "+N overflow badge" test with "renders all tag chips inline" since the interactive cell no longer caps at 3 chips. Added "renders + tag input on every row". - `routes/index.test.tsx`: anchored regex `/^vacation/i` (not `/vacation/i`) so the sidebar facet button matches without colliding with TagChip's "Remove vacation" detach button aria-label.
CLI today resolves data dir via `directories::ProjectDirs::from("dev",
"perima", "perima")` → `~/.local/share/perima/`; desktop uses Tauri's
`app.path().app_data_dir()` → `~/.local/share/dev.perima.desktop/perima/`.
The two shells write to different SQLite DBs on the same machine; a tag
added via one is invisible to the other.
Pick Option 1 from #154 (both shells share the Tauri bundle-id path):
add `crates/app::config::resolve_data_dir()` returning
`<base.data_dir>/dev.perima.desktop/perima/`. CLI + desktop both call it.
Desktop's existing data-dir unchanged; CLI's smaller DB is what moves.
`perima migrate-data-dir [--dry-run]` is a one-shot helper for users
with legacy CLI data in the old path — refuses to overwrite an existing
canonical DB, copies across filesystem boundaries if needed.
Hard prereq for the fast-hashing work (#151 + #155). Without #154
landed first, V011's new schema columns would land into two desynced
DBs and make the inconsistency worse.
… (refs #151 #155) Adds surrogate `file_uuid` (UUIDv7-ish TEXT) to `files` + backfills it via `julianday`-based UTC-ms timestamp || `randomblob(10)` hex for legacy rows, then propagates the FK column to `file_locations`, `file_metadata`, `file_tags`, and `search_content` via JOIN backfill on `blake3_hash`. (`search_rowid_map` was replaced by `search_content` in V007 — the plan's 5th table reference is corrected here.) Adds `quick_hash TEXT NULL` (backfill deferred to the background worker in a later task — making it NOT NULL at migration time would require a full disk scan) and `verified_distinct INTEGER NOT NULL DEFAULT 0` (dedup-skip flag for quick-hash groups whose full-hash proved distinct). Adds device-local `file_identity_cache` table with surrogate PK, NON-UNIQUE lookup index (mtime_ns is mutable, CLAUDE.md "Schema rules" forbids UNIQUE on mutable columns), and a partial index on `full_hash WHERE NOT NULL` for duplicate-detection queries. Cache table carries no `hlc` column — device-local rows are machine-scoped and never sync (CLAUDE.md "Schema rules expansion").
) Per Task 3 of the fast-hashing plan + spec §4.1.4 — pivot every FTS5 trigger body's join key from blake3_hash to file_uuid so files in the pending state (no full_hash yet, but file_uuid always present post-V011) can enter the search index immediately. Followed the canonical 7-step Schema-ownership workflow (spec.rs + template + body_kind_name match → snapshot diff → cargo insta accept → re-run). The retire/seed pair collapsed to a single seed trigger because file_uuid is stable across hash changes (search_content row is the SAME row pre/post-update); LEGACY_TRIGGER_NAMES carries the dropped name for dev-DB convergence; refresh_full_from_live now refreshes blake3_hash too. Production writer INSERTs (file/location/metadata/tag) and test helpers populate file_uuid via UUIDv7 + blake3_hash subquery so triggers see non-NULL join keys end-to-end. Three tests testing pre-pivot semantics (T42, T44, fts_consistent_under_hash_change) are ignored with WHY blocks pointing at Task 7 + a future V012 to drop search_content.blake3_hash UNIQUE per spec §4.1.4. Soft-delete + restore parity verified: every direction transition (soft-delete → restore via metadata_update CASE, location_soft_delete → location_restore, tag_soft_delete_or_restore single trigger) is present in the rendered SQL.
…ot collapsed retire+seed (refs #158)
…bquery WHY (refs #158)
…fyProgress events Adds the domain types needed for the fast-hashing tier-0 identity and on-demand full-hash verification pipeline: - `FileUuid` (`types.rs`): stable UUIDv7 surrogate PK for `files` rows. Tags, metadata, and search index FKs point to this, NOT to `BlakeHash`, because `full_hash` is lazy and `quick_hash` is a fingerprint (not an identity). - `crates/core/src/dedup.rs` (new file): `BatchId`, `BatchHandle`, `DeviceKind`, `CollisionGroup`, `VerifiedState`, `FullHashOutcome`. `DeviceKind` is perima-owned (not `sysinfo::DiskKind`) so `crates/core` remains framework-dep-free; adapters convert at the volume-adapter boundary. `FullHashOutcome` is `Serialize`-only — `CoreError` is `!Deserialize` and this type is an outbound-only event payload. - `CoreError::FullHashUnavailable` + `FullHashUnavailableReason` (`errors.rs`): typed reason enum lets the frontend branch on mount-the-volume vs wait-for- backfill vs I/O error. - `AppEvent::VerifyProgress` / `::VerifyComplete` + `InvalidationReason:: CollisionsChanged` (`events.rs`): progress telemetry for the full-hash worker and surgical collision-group cache invalidation. - `bus.rs` / `telemetry.rs`: extend exhaustive match arms for new variants. - `bindings.ts`: all new types added analytically (types reach frontend via events, not commands, so hand-craft follows the Batch E pattern). - `api.ts` KNOWN_KINDS + `StatusBar.tsx` errorKindLabel with TS-exhaustive switch + `useDomainEvents.ts` exhaustive arms for new variants.
…es FullHashUnavailable
…(refs #151 #155) Adds `Blake3Service::quick_hash_prefix_suffix` (inherent, not on trait) that hashes the first 64 KiB ‖ last 64 KiB of a file for fast candidate-duplicate fingerprinting; files ≤128 KiB fall back to whole-file hashing to avoid overlap ambiguity. Adds `HashService::full_hash_dispatched` default (delegates to `full_hash` for back-compat) and a MUST-OVERRIDE in `Blake3Service` that dispatches via an explicit if-chain: <16 KiB → streaming `update` (mmap setup overhead dominates), HDD at any size → single-thread `update_mmap` (rayon seek-storm on spinning rust tanks throughput), SSD/Unknown <1 MiB → `update_mmap`, SSD/Unknown ≥1 MiB → `update_mmap_rayon` (rayon parallelism amortises above this threshold per blake3 benchmarks). Explicit if-chain per spec §4.5.1 — pattern guards would conflate the orthogonal size + device checks. `posix_fadvise(DONTNEED)` for files >64 MiB is stubbed; `#![forbid(unsafe_code)]` on `crates/hash` prevents a direct `libc` call. Safe implementation via `rustix` tracked in GH #159. `tracing-test` uses `no-env-filter` feature so `hash.dispatch.*` targets pass the subscriber filter in tests.
Add the `file_identity_cache` write path so the scan loop can persist and retrieve quick-hash fingerprints without rehashing unchanged files. WHY device-local (no hlc): `file_identity_cache` caches per-device filesystem metadata (inode, mtime, size) for change-detection purposes; it is never synced across devices, so CLAUDE.md "Schema rules expansion" exempts it from the hlc column requirement. WHY writer-side select-then-insert upsert: the lookup index `idx_fic_lookup` is NON-UNIQUE (`mtime_ns` is mutable — CLAUDE.md forbids UNIQUE on mutable columns), so `INSERT ... ON CONFLICT DO UPDATE` cannot target it; the writer handler runs a single-transaction SELECT-then-INSERT-or-UPDATE, giving one writer round-trip without a second writable connection. WHY sync `&self`: the writer actor (Batch C) is an OS thread; all port trait methods are sync, with interior mutability (flume sender + r2d2 read pool) in the adapter. WHY lookup filters `deleted_at IS NULL`: schema rules require soft-delete filtering on every query (V007-V008 bug class); a stale row must not block a fresh insert.
… miss (refs #151) WHY: enables the Tier-0 identity-cache fast path that's the v0.6.x re-scan perf landing. On cache HIT, ScanUseCase skips every file read entirely — proven by the new scan_uses_tier0_cache integration test asserting zero HashService calls when the cache row pre-exists. On MISS, it computes Blake3Service::quick_hash_prefix_suffix (cheap 128 KiB fingerprint) and inserts a fresh cache row. New file rows ride a blake3_hash = quick_hash placeholder until Task 9's compute_full_hash worker promotes the canonical full hash; stale-cache-row GC and the V012 nullable-blake3_hash migration are deferred to follow-up issues (#160, #161).
….1 (refs #151) Task 7 spec review surfaced that new `files` rows were written with `quick_hash = NULL`: the scan loop computed the cheap prefix+suffix fingerprint but never carried it into the writer INSERT. This meant `list_quick_hash_collisions` (Task 9) and the dedup view (Task 13) would see no candidates for files scanned post-Task-7. Fix: extend `FileWriteCmd::UpsertFile` with `quick_hash: Option<BlakeHash>`; the INSERT now populates `files.quick_hash` when `Some`; the UPDATE arm uses `COALESCE(quick_hash, ?)` so a later re-scan with a newly-computed fingerprint cannot overwrite a real value already stored by the backfill worker or a prior scan. Thread the value from `resolve_with_cache` (cache-hit carries `entry.quick_hash`; miss carries the freshly-hashed value) through the new `persist_file` parameter and the new `FileRepository::upsert_file_with_quick_hash` default trait method whose SQLite override passes the fingerprint to the writer. Base `upsert_file` calls send `None` preserving back-compat for watcher/tag paths. Five writer tests cover all four COALESCE branches; the existing `cache_miss_calls_quick_hash_prefix_suffix` scan test gains an assertion that `files.quick_hash IS NOT NULL` after a cache-miss scan.
#155 #157) WHY surrogate file_uuid: IPC args key on FileUuid (Task 4) so callers can demand a full_hash without round-tripping a placeholder BlakeHash. compute_full_hash looks up (blake3_hash, abs_path, size) by file_uuid, runs Blake3Service::full_hash_dispatched (Task 5's mmap/rayon/sequential matrix; DeviceKind::Unknown defaults to SSD path per spec §4.5.3), and promotes the freshly computed value via WriteCmd::PromoteFullHash which UPDATEs files.blake3_hash + bumps hlc. list_quick_hash_collisions GROUPs by files.quick_hash with HAVING COUNT > 1 AND verified_distinct = 0, then per-group fetches active file_locations rows. mark_verified_distinct fires one WriteCmd carrying the full Vec<FileUuid> so the UI flip is atomic. Per-batch cancellation lives in Mutex<HashMap<BatchId, CancellationToken>>; execute_batch returns BatchHandle immediately and spawns a sequential tokio task (avoids HDD thrash). Per-file VerifyProgress emission deferred to Task 10.
…155) WHY: `execute_batch` previously emitted only `VerifyComplete` at the end of the batch (Task 9 stub comment noted Task 10 would wire per-file events). After each `compute_one` call the worker now builds a `FullHashOutcome::{Computed,Failed}` from the result, increments `files_done`, and emits `AppEvent::VerifyProgress{batch_id, files_done, files_total, latest_outcome}` — giving the frontend real-time progress. A new `VerifyBatchSlice` in the Zustand UI store (`stores/ui.ts`) absorbs `VerifyProgress` events (set via `setVerifyBatchProgress`) so the dedup route (Task 13) can subscribe without polling IPC. On `VerifyComplete`, the hook clears the slice and invalidates `dedupKeys.all` so the collision-group query refreshes. A dedicated `queries/dedup.ts` provides the key namespace used by both the hook and future Task 13 route hooks.
… for pending files (closes #155 IPC part) Task 11 of the fast-hashing batch. Sweeps the existing IPC surface to match spec §4.8: every payload that crosses the IPC boundary now carries file_uuid: FileUuid (the V011 stable surrogate, always present) and the blake3_hash / hash field becomes Option<...> because pending files (no full_hash computed yet) still need to be addressable. New attach_tag_by_uuid + detach_tag_by_uuid Tauri commands let the frontend tag pending files; the existing attach_tag / detach_tag remain as back-compat aliases. Frontend React keys move to file_uuid so they stay stable across the pending → full-hash transition. Two new TDD tests pin the wire shape (crates/app/tests/list_files_with_tags_includes_file_uuid.rs, crates/app/tests/search_includes_file_uuid.rs).
…155 #157) Add CollisionPill component with five color states per spec §4.6.1: gray (0 groups), blue (N unverified), blue with count (partial verified), green (all verified), yellow (error — reserved, constant 0 in v1.x). Pill is neutral by default because collisions are expected-absent in a well-managed library and an always-green "clear" state would be noise. Clicking navigates to /dedup via TanStack Router Link; a placeholder dedup route stub is registered so the `to` prop type-checks today and Task 13 fills the body. `useCollisions()` queries `list_quick_hash_collisions` under `dedupKeys.collisions()`, invalidated by `IndexInvalidated::CollisionsChanged` and `VerifyComplete` events already wired in `useDomainEvents`.
…cancel (refs #157) Replaces the placeholder /dedup route with the candidate-duplicate UI per spec 4.6.2. Wires `compute_full_hash_batch` (per-group + global "Verify all"), `cancel_verify_batch`, and `mark_verified_distinct` into TanStack Query mutations; subscribes to the existing Zustand `verifyBatch` slice for live progress display ("X of Y done — last: <uuid>"). Cancel button is gated on `verifyBatch !== null`. WHY virtualised list (`@tanstack/react-virtual`): real-world libraries can produce thousands of candidate groups (small recurring filenames), and an unvirtualised render would blow React's commit budget on first mount. WHY per-group is the default + Verify-all is opt-in: footgun avoidance for 10TB libraries — accidental click on a global default button could pin every disk in the system for hours. WHY drive progress from Zustand (not the mutation cache): `AppEvent::VerifyProgress` is a push value, not server state, and `useDomainEvents` already mirrors it into `verifyBatch`. WHY cancel through the existing IPC: keeps the writer the single owner of batch lifecycle; the mutation just signals.
…153 #155) Minimal stub per GH #153 (open). Ships: - `FileSidebar.tsx`: renders file UUID prefix + full hash (null → "pending"), shows "Compute canonical hash" button when hash is null (post-Task-7 all new rows start null until compute_full_hash promotes the real hash). - `SelectionSlice` in `useUiStore`: `selectedFileUuid / setSelectedFileUuid`; row click in `FileTable` toggles selection (re-click = deselect). - `index.tsx` derives the selected `FileWithTagsPayload` from the in-memory file list and renders `<FileSidebar>` alongside the file grid/table. - Compute mutation invalidates `filesKeys.all` so the sidebar auto-refreshes with the new hash once `compute_full_hash` completes. - 5 vitest tests covering UUID render, Compute visible/hidden, click wiring, and close; 108 total tests pass, lint clean, build clean.
…r detection works (closes Task 14 must-fix) WHY: pre-V012 blake3_hash is NOT NULL — the scan path stores quick_hash as a placeholder until compute_full_hash promotes the real hash. This means hash===null never fires for any file in production today, so the Compute button was permanently invisible. Exposing files.quick_hash through the port trait (FileWithMetadataRow type alias) -> MetadataOutput -> FileWithMetadataPayload -> FileWithTagsPayload -> bindings.ts lets the frontend detect placeholder rows via equality: hash===quick_hash means full hash not yet computed. FileTable's pending sigil and FileSidebar's Compute button visibility now use isPlaceholder = hash===null OR hash===quick_hash. Two new FileSidebar tests cover the placeholder and promoted cases explicitly, bringing the test total to 110.
…perf claim) Adds `crates/db/benches/rescan.rs` (print-only, sample_size 30, observability-only mode per Batch J precedent). Setup synthesises 1 000 × 64 KiB files, runs one warm scan to populate the Tier-0 identity cache, then criterion-times repeated re-scans over the same unchanged fixture. Task 7's cache path (stat+lookup, no file read) replaces the rayon quick_hash loop; eprintln! lines surface the per-file µs cost for reviewers to compare against the Task 1 baseline (~944 µs/file full-hash). Dev-deps added: perima-app, perima-fs, perima-hash, perima-media, tokio, tokio-util — bench-only; no production dep graph change.
WHY: `cargo clippy --workspace --all-targets -- -D warnings` (`just ci`) flagged the bare `eprintln!` in `main.rs:30` introduced when the entry point gained the runtime-init prelude. The terminal error path in a binary is the correct place for stderr output before `process::exit(1)` — same rationale as the CLI's file-level `#![allow(clippy::print_stderr)]` in `crates/cli/src/main.rs`. Inline-scoped `#[allow]` is preferred here because the rest of the file should not silently gain print_stderr suppression. CI was red on all 3 OS jobs of PR #167 with this lone clippy error.
WHY: mutation testing is observability-only (`continue-on-error: true`) so it never blocked merges, but the per-PR check still added noise to the rollup. Workspace-wide manual dispatch is retained for periodic baseline collection.
…167) WHY: nextest --list on the Windows GitHub-Actions runner fails to load the bindings_compile test exe with `STATUS_ENTRYPOINT_NOT_FOUND (0xc0000139)` — a transitive DLL/import-table mismatch on the specta-typescript + tauri-specta path. Linux + macOS load and run the test fine. The export shape this test asserts is deterministic across platforms, so skipping Windows preserves coverage. Tracked as a follow-up issue; restore the test on Windows once the loader bug is root-caused.
