# Tasks: Feedback Loop UX

## T1: Add `remove_like` and `remove_save` to UserStateIndex

**File:** `tidal/src/entities/user_state.rs`

Add two new public methods following the pattern of the existing `remove_hide` and `remove_block_creator`. Add unit tests. **Status: COMPLETE.** Methods added at lines 284 and 315.

## T2: Add `skip_counter` field to TidalDb

**File:** `tidal/src/db/mod.rs`, `tidal/src/db/from_parts.rs`

Add `skip_counter: DashMap<(u64, u32), u8>` field to the `TidalDb` struct. Initialize as `DashMap::new()` in both `from_config()` and `from_parts()`. **Status: COMPLETE.**

## T3: Implement `FeedbackAction`, `FeedbackState`, and `submit_feedback`

**File:** `tidal/src/db/feedback.rs` (NEW)

Define FeedbackAction enum (11 variants, Copy), FeedbackState struct (5 bools), SKIP_ESCALATION_THRESHOLD constant, submit_feedback method, feedback_state method, and try_negative_preference_update private method. **Status: COMPLETE.** Full implementation with 22 unit tests.

## T4: Wire module and re-exports

**Files:** `tidal/src/db/mod.rs`, `tidal/src/lib.rs`

Add `pub mod feedback;` to `db/mod.rs`. Re-export `FeedbackAction` and `FeedbackState` from `lib.rs`. **Status: COMPLETE.**

## T5: Unit tests for feedback module

**File:** `tidal/src/db/feedback.rs` (test module)

21 unit tests covering all 11 action variants, feedback_state, skip escalation, undo no-ops, and edge cases. **Status: COMPLETE.** All 21 tests pass.

## T6: Integration tests

**File:** `tidal/tests/p1_feedback_loop.rs` (NEW)

10 integration tests: like/unlike roundtrip, hide/unhide roundtrip, dislike/undo roundtrip, mute/unmute creator, save/unsave, skip escalation, default state, multi-user independence, negative preference update, combined actions. **Status: COMPLETE.** All 10 tests pass.

## T7: Clippy and fmt clean-up

Run cargo fmt and cargo clippy. Fixed: added `#[allow(clippy::struct_excessive_bools)]` on FeedbackState, added `Copy` derive on FeedbackAction, converted match-return patterns to `let...else`. **Status: COMPLETE.** Zero warnings from feedback module files.
