+# Deep Performance Audit Report
+
+**Date:** 2026-02-12
+**Branch:** `perf-audit` (e9bacc94)
+**Parent:** `039ab1c2` (master, v0.6.1)
+
+---
+
+## Methodology
+
+1. **Baseline** — measured p50/p95 latency for all major commands with warm cache
+2. **Profile** — used macOS `sample` profiler and `EXPLAIN QUERY PLAN` to identify hotspots
+3. **Golden output** — captured exact numeric outputs before changes as equivalence oracle
+4. **One lever per change** — each optimization isolated and independently benchmarked
+5. **Revert threshold** — any optimization <1.1x speedup reverted per audit rules
+
+---
+
+## Baseline Measurements (warm cache, release build)
+
+| Command | Latency | Notes |
+|---------|---------|-------|
+| `who --path src/core/db.rs` (expert) | 2200ms | **Hotspot** |
+| `who --active` | 83-93ms | Acceptable |
+| `who workload` | 22ms | Fast |
+| `stats` | 107-112ms | **Hotspot** |
+| `search "authentication"` | 1030ms | **Hotspot** (library-level) |
+| `list issues -n 50` | ~40ms | Fast |
+
+---
+
+## Optimization 1: INDEXED BY for DiffNote Queries
+
+**Target:** `src/cli/commands/who.rs` — expert and reviews query paths
+
+**Problem:** SQLite query planner chose `idx_notes_system` (38% selectivity, 106K rows) over `idx_notes_diffnote_path_created` (9.3% selectivity, 26K rows) for path-filtered DiffNote queries. The partial index `WHERE noteable_type = 'MergeRequest' AND type = 'DiffNote'` is far more selective but the planner's cost model didn't pick it.
+
+**Change:** Added `INDEXED BY idx_notes_diffnote_path_created` to all 8 SQL queries across `query_expert`, `query_expert_details`, `query_reviews`, `build_path_query` (probes 1 & 2), and `suffix_probe`.
+
+**Results:**
+
+| Query | Before | After | Speedup |
+|-------|--------|-------|---------|
+| expert (specific path) | 2200ms | 56-58ms | **38x** |
+| expert (broad path) | 2200ms | 83ms | **26x** |
+| reviews | 1800ms | 24ms | **75x** |
+
+**Isomorphism proof:** `INDEXED BY` only changes which index the planner uses, not the query semantics. Same rows matched, same ordering, same output. Verified by golden output comparison across 5+ runs.
+
+---
+
+## Optimization 2: Conditional Aggregates in Stats
+
+**Target:** `src/cli/commands/stats.rs`
+
+**Problem:** 12+ sequential `COUNT(*)` queries each requiring a full table scan of `documents` (61K rows). Each scan touched the same pages but couldn't share work.
+
+**Changes:**
+- Documents: 5 sequential COUNTs -> 1 query with `SUM(CASE WHEN ... THEN 1 END)`
+- FTS count: `SELECT COUNT(*) FROM documents_fts` (virtual table, slow) -> `SELECT COUNT(*) FROM documents_fts_docsize` (shadow B-tree table, 19x faster)
+- Embeddings: 2 queries -> 1 with `COUNT(DISTINCT document_id), COUNT(*)`
+- Dirty sources: 2 queries -> 1 with conditional aggregates
+- Pending fetches: 2 queries -> 1 each (discussions, dependents)
+
+**Results:**
+
+| Metric | Before | After | Speedup |
+|--------|--------|-------|---------|
+| Warm median | 112ms | 66ms | **1.70x** |
+| Cold | 1220ms | ~700ms | ~1.7x |
+
+**Golden output verified:**
+
+```
+total:61652, issues:8241, mrs:10018, discussions:43393, truncated:63
+fts:61652, embedded:61652, chunks:88161
+```
+
+All values match exactly across before/after runs.
+
+**Isomorphism proof:** `SUM(CASE WHEN x THEN 1 END)` is algebraically identical to `COUNT(*) WHERE x`. The FTS5 shadow table `documents_fts_docsize` has exactly one row per FTS document by SQLite specification, so `COUNT(*)` on it equals the virtual table count.
+
+---
+
+## Investigation: Two-Phase FTS Search (REVERTED)
+
+**Target:** `src/search/fts.rs`, `src/cli/commands/search.rs`
+
+**Hypothesis:** FTS5 `snippet()` generation is expensive. Splitting search into Phase 1 (score-only MATCH+bm25) and Phase 2 (snippet for filtered results only) should reduce work.
+
+**Implementation:** Created `fetch_fts_snippets()` that retrieves snippets only for post-filter document IDs via `json_each()` join.
+
+**Results:**
+
+| Metric | Before | After | Improvement |
+|--------|--------|-------|-------------|
+| search (limit 20) | 1030ms | 995ms | 3.5% |
+
+**Decision:** Reverted. Per audit rules, <1.1x speedup does not justify added code complexity.
+
+**Root cause:** The bottleneck is not snippet generation but `MATCH` + `bm25()` scoring itself. Profiling showed `strspn` (FTS5 tokenizer) and `memmove` as the top CPU consumers. The same query runs in 30ms on system sqlite3 but 1030ms in rusqlite's bundled SQLite — a ~125x gap despite both being SQLite 3.51.x compiled at -O3.
+
+---
+
+## Library-Level Finding: Bundled SQLite FTS5 Performance
+
+**Observation:** FTS5 MATCH+bm25 queries are ~125x slower in rusqlite's bundled SQLite vs system sqlite3.
+
+| Environment | Query Time | Notes |
+|-------------|-----------|-------|
+| System sqlite3 (macOS) | 30ms (with snippet), 8ms (without) | Same .db file |
+| rusqlite bundled | 1030ms | `features = ["bundled"]`, OPT_LEVEL=3 |
+
+**Profiler data (macOS `sample`):**
+- Top hotspot: `strspn` in FTS5 tokenizer
+- Secondary: `memmove` in FTS5 internals
+- Scaling: ~5ms per result (limit 5 = 497ms, limit 20 = 995ms)
+
+**Possible causes:**
+- Bundled SQLite compiled without platform-specific optimizations (SIMD, etc.)
+- Different memory allocator behavior
+- Missing compile-time tuning flags
+
+**Recommendation for future:** Investigate switching from `features = ["bundled"]` to system SQLite linkage, or audit the bundled compile flags in the `libsqlite3-sys` build script.
+
+---
+
+## Exploration Agent Findings (Informational)
+
+Four parallel exploration agents surveyed the entire codebase. Key findings beyond what was already addressed:
+
+### Ingestion Pipeline
+- Serial DB writes in async context (acceptable — rusqlite is synchronous)
+- Label ingestion uses individual inserts (potential batch optimization, low priority)
+
+### CLI / GitLab Client
+- GraphQL client recreated per call (`client.rs:98-100`) — caches connection pool, minor
+- Double JSON deserialization in GraphQL responses — medium priority
+- N+1 subqueries in `list` command (`list.rs:408-423`) — 4 correlated subqueries per row
+
+### Search / Embedding
+- No N+1 patterns, no O(n^2) algorithms
+- Chunking is O(n) single-pass with proper UTF-8 safety
+- Ollama concurrency model is sound (parallel HTTP, serial DB writes)
+
+### Database / Documents
+- O(n^2) prefix sum in `truncation.rs` — low traffic path
+- String allocation patterns in extractors — micro-optimization territory
+
+---
+

+Highest-impact gaps I see in the current plan:

+2. `lore notes` has no pagination contract, so large exports and deterministic resumption are weak.
+3. Migration `022` is high-risk (table rebuild + FTS + junction tables) without explicit integrity gates.
+4. Note-doc freshness is incomplete for upstream note deletions and parent metadata changes (labels/title).
+
+Below are my best revisions, each with rationale and a git-diff-style plan edit.
+
+---
+
+1. **Add gated rollout + rollback controls**
+Rationale: You can still “ship together” while reducing blast radius. This makes recovery fast if note-doc generation causes DB/embedding pressure.
+

++1) Enable `notes_cli`
++2) Run note-doc backfill in bounded batches
++3) Enable `note_documents` for continuous updates
++
++Rollback:
++- Disabling `feature.note_documents` stops new note-doc generation without affecting issue/MR/discussion docs.
+```
+
+2. **Add keyset pagination + deterministic ordering**
+Rationale: Needed for year-long reviewer analysis and reliable “continue where I left off” behavior under concurrent updates.
+
+```diff
+@@ pub struct NoteListFilters<'a> {
+     pub limit: usize,
++    pub cursor: Option<&'a str>,        // keyset token "<sort_ms>:<id>"

+
+3. **Make `for-issue` / `for-mr` project-scoped**
+Rationale: IIDs are not globally unique. Requiring project avoids false positives and hard-to-debug cross-project leakage.
+
+```diff
+@@ pub struct NotesArgs {
+-    #[arg(long = "for-issue", help_heading = "Filters", conflicts_with = "for_mr")]

+     pub for_mr: Option<i64>,
+```
+
+4. **Upgrade path filtering semantics**
+Rationale: Review comments often reference renames/moves. Restricting to `position_new_path` misses relevant notes.
+
+```diff
+@@ pub struct NotesArgs {
+-    /// Filter by file path (trailing / for prefix match)

+@@ query_notes filter mappings
+-- `path` ... n.position_new_path ...
++- `path` applies to `n.position_new_path` and optionally `n.position_old_path`.
++- `glob` mode translates `*`/`?` to SQL LIKE with escaping.
+```
+
+5. **Add explicit performance indexes (new migration)**
+Rationale: `notes` becomes a first-class query surface; without indexes, filters degrade quickly at 10k+ note scale.
+
+```diff
+@@ ## Phase 1: `lore notes` Command
++### Work Chunk 1E: Query Performance Indexes
++**Files:** `migrations/023_notes_query_indexes.sql`, `src/core/db.rs`
++
++Add indexes:
++- `notes(project_id, created_at DESC, id DESC)`
++- `notes(author_username, created_at DESC, id DESC) WHERE is_system = 0`
++- `notes(discussion_id)`
++- `notes(position_new_path)`
++- `notes(position_old_path)`
++- `discussions(issue_id)`
++- `discussions(merge_request_id)`
+```
+
+6. **Harden migration 022 with transactional integrity checks**
+Rationale: This is the riskiest part of the plan. Add hard fail-fast checks so corruption cannot silently pass.
+
+```diff
+@@ ### Work Chunk 2A: Schema Migration (022)
++Migration safety requirements:
++- Execute in a single `BEGIN IMMEDIATE ... COMMIT` transaction.
++- Capture and compare pre/post row counts for `documents`, `document_labels`, `document_paths`, `dirty_sources`.
++- Run `PRAGMA foreign_key_check` and abort on any violation.
++- Run `PRAGMA integrity_check` and abort on non-`ok`.
++- Rebuild FTS and assert `documents_fts` rowcount equals `documents` rowcount.
+```
+
+7. **Add note deletion + parent-change propagation**
+Rationale: Current plan handles create/update ingestion but not all staleness paths. Without this, note documents drift.
+
+```diff
+@@ ## Phase 2: Per-Note Documents
++### Work Chunk 2G: Freshness Propagation
++**Files:** `src/ingestion/discussions.rs`, `src/ingestion/mr_discussions.rs`, `src/documents/regenerator.rs`
++
++Rules:
++- If a previously stored note is missing from upstream payload, delete local note row and enqueue `(note, id)` for document deletion.
++- When parent issue/MR title or labels change, enqueue descendant note docs dirty (notes inherit parent metadata).
++- Keep idempotent behavior for repeated syncs.
+```
+
+8. **Separate FTS coverage from embedding coverage**
+Rationale: Biggest cost/perf risk is embeddings. Index all notes in FTS, but embed selectively with policy knobs.
+
+```diff
+@@ ## Estimated Document Volume Impact
+-FTS5 handles this comfortably. Embedding generation time scales linearly (~4x increase).
++FTS5 handles this comfortably. Embedding generation is policy-controlled:
++- FTS: index all non-system note docs
++- Embeddings default: only notes with body length >= 40 chars (configurable)
++- Add config: `documents.note_embeddings.min_chars`, `documents.note_embeddings.enabled`
++- Prioritize unresolved DiffNotes before other notes during embedding backfill
+```
+
+9. **Bring structured reviewer profiling into scope (not narrative reporting)**
+Rationale: This directly serves the stated use case and makes the feature compelling immediately.
+
+```diff
+@@ ## Non-Goals
+-- Adding a "reviewer profile" report command (that's a downstream use case built on this infrastructure)
++- Generating free-form narrative reviewer reports.
++  A structured profiling command is in scope.
++
++## Phase 3: Structured Reviewer Profiling
++Add `lore notes profile --author <user> --since <window>` returning:
++- top commented paths
++- top parent labels
++- unresolved-comment ratio
++- note-type distribution
++- median comment length
+```
+
+10. **Add operational SLOs + robot-mode status for note pipeline**
+Rationale: Reliability improves when regressions are observable, not inferred from failures.
+
+```diff
+@@ ## Verification Checklist
++Operational checks:
++- `lore -J stats` includes per-`source_type` document counts (including `note`)
++- Add queue lag metrics: oldest dirty note age, retry backlog size
++- Add extraction error breakdown by `source_type`
++- Add smoke assertion: disabling `feature.note_documents` leaves other source regeneration unaffected

+Below are the strongest revisions I’d make, excluding everything in your `## Rejected Recommendations` list.
+
+1. **Add a Phase 0 for stable note identity before any note-doc generation**
+Rationale: your current plan still allows note document churn because Issue discussion ingestion is delete/reinsert-based. That makes local `notes.id` unstable, causing unnecessary dirtying/regeneration and potential stale-doc edge cases. Stabilizing identity first (upsert-by-GitLab-ID + sweep stale) improves correctness and cuts repeated work.
+
+```diff
+@@ ## Design
+-Two phases, shipped together as one feature:
++Three phases, shipped together as one feature:
++- **Phase 0 (Foundation):** Stable note identity in local DB (upsert + sweep, no delete/reinsert churn)
+ - **Phase 1 (Option A):** `lore notes` command — direct SQL query over the `notes` table with rich filtering
+ - **Phase 2 (Option B):** Per-note documents — each non-system note becomes its own searchable document in the FTS/embedding pipeline
+@@
++## Phase 0: Stable Note Identity
++
++### Work Chunk 0A: Upsert/Sweep for Issue Discussion Notes
++**Files:** `src/ingestion/discussions.rs`, `migrations/022_notes_identity_index.sql`, `src/core/db.rs`
++**Implementation:**
++- Add unique index: `UNIQUE(project_id, gitlab_id)` on `notes`
++- Replace delete/reinsert issue-note flow with upsert + `last_seen_at` sweep (same durability model as MR note sweep)
++- Ensure `insert_note/upsert_note` returns the stable local row id for both insert and update paths
+```
+
+2. **Replace `source_type` CHECK constraints with a registry table + FK in migration**
+Rationale: table CHECKs force full table rebuild for every new source type forever. A `source_types` table with FK keeps DB-level integrity and future extensibility without rebuilding `documents`/`dirty_sources` every time. This is a major architecture hardening win.
+
+```diff

++1. Create `source_types(name TEXT PRIMARY KEY)` and seed: `issue, merge_request, discussion, note`
++2. Rebuild `dirty_sources` and `documents` to replace CHECK with `REFERENCES source_types(name)`

+```
+
+3. **Mark note documents dirty only when note semantics actually changed**
+Rationale: current loops mark every non-system note dirty every sync. With 8k+ notes this creates avoidable queue pressure and regeneration time. Change-aware dirtying (inserted/changed only) gives major performance and stability improvements.
+
+```diff

++// changed_semantics should include: body, note_type, path/line positions, resolvable/resolved/resolved_by, updated_at
+```
+
+4. **Expand filters to support real analysis windows and resolution state**
+Rationale: reviewer profiling usually needs bounded windows and both resolved/unresolved views. Current `unresolved: bool` is too narrow and one-sided. Add `--until` and tri-state resolution filtering for better analytical power.
+
+```diff

+```
+
+5. **Broaden index strategy to match actual query shapes, not just author queries**
+Rationale: `idx_notes_user_created` helps one path, but common usage also includes project+time scans and unresolved filters. Add two more partial composites for high-selectivity paths.
+
+```diff

+
+6. **Improve per-note document payload with structured metadata header + minimal thread context**
+Rationale: isolated single-note docs can lose meaning. A small structured header plus lightweight context (parent + one preceding note excerpt) improves semantic retrieval quality substantially without re-bundling full threads.
+

+
+7. **Add first-class export modes for downstream profiling pipelines**
+Rationale: this makes the feature much more useful immediately (LLM prompts, notebook analysis, external scripts) without adding a profiling command. It stays within your non-goals and increases adoption.
+
+```diff

+@@ ### Work Chunk 1C: Human & Robot Output Formatting
++Add `print_list_notes_csv()` and `print_list_notes_jsonl()`:
++- CSV columns mirror `NoteListRowJson` field names
++- JSONL emits one note object per line for streaming pipelines
+```
+
+8. **Strengthen verification with idempotence + migration data-preservation checks**
+Rationale: this feature touches ingestion, migrations, indexing, and regeneration. Add explicit idempotence/perf checks so regressions surface early.

+
+3. Fix `--since/--until` semantics and validation
+Why: reusing `parse_since` for `until` creates ambiguous windows and off-by-boundary behavior; your own example `--since 90d --until 180d` is chronologically reversed.

+6. Replace manual CSV escaping with `csv` crate
+Why: manual RFC4180 escaping is fragile (quotes/newlines/multi-byte edge cases). This is exactly where a mature library reduces long-term bug risk.
+```diff
+@@ Work Chunk 1C: Human & Robot Output Formatting

+
+7. Add `--contains` lexical body filter to `lore notes`
+Why: useful middle ground between metadata filtering and semantic search; great for reviewer-pattern mining without requiring FTS query syntax.
+```diff

+```
+
+8. Reduce note-document embedding noise by slimming metadata header
+Why: current verbose key-value header repeats low-signal tokens and consumes embedding budget. Keep context, but bias tokens toward actual review text.
+```diff

++ state: {resolved|unresolved} (only when resolvable)
++
++ {body}
++
++Keep detailed metadata in structured document columns/labels/paths/url,
++not repeated in verbose text.
+```
+
+9. Add explicit performance regression checks for the new hot paths
+Why: this feature increases document volume ~4x; you should pin acceptable query behavior now so future changes don’t silently degrade.
+```diff

++   - `lore search --type note ...` remains deterministic and completes successfully

+4. **Fix project-scoping and time-window semantics in `lore notes`**
+Why this is better: the plan currently has a contradiction: clap `requires = "project"` blocks use of `defaultProject`, while query layer says default fallback is allowed. Also, `since/until` parsing should use one shared “now” to avoid subtle drift and inverted windows.

+Here are the highest-impact revisions I’d make. None of these repeat anything in your `## Rejected Recommendations`.
+
+1. **Add immutable reviewer identity (`author_id`) as a first-class key**
+Why this improves the plan: the PRD’s core use case is year-scale reviewer profiling. Usernames are mutable in GitLab, so username-only filtering will fragment one reviewer into multiple identities over time. Adding `author_id` closes that correctness hole and makes historical analysis reliable.
+
+```diff
+@@ Problem Statement
+-1. **Query individual notes by author** — the `--author` filter on `lore search` only matches the first note's author per discussion thread
++1. **Query individual notes by reviewer identity** — support both mutable username and immutable GitLab `author_id` for stable longitudinal analysis
+
+@@ Phase 0: Stable Note Identity
++### Work Chunk 0D: Immutable Author Identity Capture
++**Files:** `migrations/025_notes_author_id.sql`, `src/ingestion/discussions.rs`, `src/ingestion/mr_discussions.rs`, `src/cli/commands/list.rs`
++
++#### Implementation
++- Add nullable `notes.author_id INTEGER` and backfill from future syncs.
++- Populate `author_id` from GitLab note payload (`note.author.id`) on both issue and MR note ingestion paths.
++- Add `--author-id <int>` filter to `lore notes`.
++- Keep `--author` for ergonomics; when both provided, require both to match.
++
++#### Indexing
++- Add `idx_notes_author_id_created ON notes(project_id, author_id, created_at DESC, id DESC) WHERE is_system = 0;`
++
++#### Tests
++- `test_query_notes_filter_author_id_survives_username_change`
++- `test_query_notes_author_and_author_id_intersection`
+```
+
+2. **Strengthen partial-fetch safety from a boolean to an explicit fetch state contract**
+Why this improves the plan: `fetch_complete: bool` is easy to misuse and fragile under retries/crashes. A run-scoped state model makes sweep correctness auditable and prevents accidental deletions when ingestion aborts midway.
+
+```diff
+@@ Phase 0: Stable Note Identity
+-### Work Chunk 0C: Sweep Safety Guard (Partial Fetch Protection)
++### Work Chunk 0C: Sweep Safety Guard with Run-Scoped Fetch State

++Add a run-scoped fetch state:
++- `FetchState::Complete`
++- `FetchState::Partial`
++- `FetchState::Failed`
++
++Only run sweep on `FetchState::Complete`.

+```
+
+3. **Add DB-level cleanup triggers for note-document referential integrity**
+Why this improves the plan: Work Chunk 0B handles the sweep path, but not every possible delete path. DB triggers give defense-in-depth so stale note docs cannot survive even if a future code path deletes notes differently.
+
+```diff
+@@ Work Chunk 0B: Immediate Deletion Propagation
+-Update both sweep functions to propagate deletion to documents and dirty_sources using set-based SQL
++Keep set-based SQL in sweep functions, and add DB-level cleanup triggers as a safety net.

++  DELETE FROM dirty_sources
++   WHERE source_type = 'note' AND source_id = new.id;
++END;
+```
+
+4. **Eliminate N+1 extraction cost with parent metadata caching in regeneration**
+Why this improves the plan: backfilling ~8k notes with per-note parent/label lookups creates avoidable query amplification. Batch caching turns repeated joins into one-time lookups per parent entity and materially reduces rebuild time.
+
+```diff
+@@ Phase 2: Per-Note Documents
++### Work Chunk 2I: Batch Parent Metadata Cache for Note Regeneration
++**Files:** `src/documents/regenerator.rs`, `src/documents/extractor.rs`

++#### Implementation
++- Add `NoteExtractionContext` cache keyed by `(noteable_type, parent_id)` containing:
++  - parent iid/title/url
++  - parent labels
++  - project path
++- In batch regeneration, prefetch parent metadata for note IDs in the current chunk.
++- Use cached metadata in `extract_note_document()` to avoid repeated parent/label queries.
++
++#### Tests
++- `test_note_regeneration_uses_parent_cache_consistently`
++- `test_note_regeneration_cache_hit_preserves_hash_determinism`
+```
+
+5. **Add embedding dedup cache keyed by semantic text hash**
+Why this improves the plan: note docs will contain repeated short comments (“LGTM”, “nit: …”). Current doc-level hashing includes metadata, so identical semantic comments still re-embed many times. A semantic embedding hash cache cuts cost and speeds full rebuild/backfill without changing search behavior.
+
+```diff

++### Work Chunk 2J: Semantic Embedding Dedup for Notes
++**Files:** `migrations/026_embedding_cache.sql`, embedding pipeline module(s), `src/documents/extractor.rs`

++- Compute `embedding_text` for notes as: normalized note body + compact stable context (`parent_type`, `path`, `resolution`), excluding volatile fields.
++- Compute `embedding_hash = sha256(embedding_text)`.
++- Before embedding generation, lookup existing vector by `(model, embedding_hash)`.
++- Reuse cached vector when present; only call embedding model on misses.
++
++#### Tests
++- `test_identical_note_bodies_reuse_embedding_vector`
++- `test_embedding_hash_changes_when_semantic_context_changes`
+```
+
+6. **Add deterministic review-signal tags as derived labels**
+Why this improves the plan: this makes output immediately more useful for reviewer-pattern analysis without adding a profile command (which is explicitly out of scope). It increases practical value of both `lore notes` and `lore search --type note` with low complexity.
+
+```diff
+@@ Non-Goals

++  - `signal:blocking`
++  - `signal:security`
++  - `signal:performance`
++  - `signal:testing`
++- Attach via existing `document_labels` flow for note documents.

++- `test_note_document_derives_signal_labels_nit`
++- `test_note_document_derives_signal_labels_security`
++- `test_signal_label_derivation_is_deterministic`
+```
+
+7. **Add high-precision note targeting filters (`--note-id`, `--gitlab-note-id`, `--discussion-id`)**
+Why this improves the plan: debugging, incident response, and reproducibility all benefit from exact addressing. This is especially useful when validating sync correctness and cross-checking a specific note/document lifecycle.

+Map realistic workflows for both human users and AI agents to identify gaps in the command surface and optimization opportunities. Each journey starts with a **problem** and traces the commands needed to reach a **resolution**.
+
+---
+
+## Part 1: Human User Flows
+
+### H1. Morning Standup Prep
+
+**Problem:** "What happened since yesterday? I need to know what moved before standup."
+
+**Flow:**
+```
+lore sync -q                              # Refresh data (quiet, no noise)
+lore issues -s opened --since 1d          # Issues that changed overnight
+lore mrs -s opened --since 1d             # MRs that moved
+lore who @me                              # My current workload snapshot
+```
+
+**Gap identified:** No single "activity feed" command. User runs 3 queries to get what should be one view. No `--since 1d` shorthand for "since yesterday." No `@me` alias for the authenticated user.
+
+---
+
+### H2. Sprint Planning: What's Ready to Pick Up?
+
+**Problem:** "We're planning the next sprint. What's open, unassigned, and actionable?"
+
+**Flow:**
+```
+lore issues -s opened -p myproject        # All open issues
+lore issues -s opened -l "ready"          # Issues labeled ready
+lore issues -s opened --has-due           # Issues with deadlines approaching
+lore count issues -p myproject            # How many total?
+```
+
+**Gap identified:** No way to filter by "unassigned" issues (missing `--no-assignee` flag). No way to sort by due date. No way to see priority/weight. Can't combine filters like "opened AND no assignee AND has due date."
+
+---
+
+### H3. Investigating a Production Incident
+
+**Problem:** "Deploy broke prod. I need the full timeline of what changed around the deploy."
+
+**Flow:**
+```
+lore sync -q                              # Get latest
+lore timeline "deploy" --since 7d         # What happened around deploys
+lore search "deploy" --type mr            # MRs mentioning deploy
+lore mrs 456                              # Inspect the suspicious MR
+lore who --overlap src/deploy/            # Who else touches deploy code
+```
+
+**Gap identified:** Timeline is keyword-based, not event-based. Can't filter by "MRs merged in the last 24 hours" directly. No way to see which MRs were merged between two dates (release diff). Would benefit from `lore mrs -s merged --since 1d`.
+
+---
+
+### H4. Preparing to Review Someone's MR
+
+**Problem:** "I was assigned to review MR !789. I need context before diving in."
+
+**Flow:**
+```
+lore mrs 789                              # Read the MR description + discussions
+lore mrs 789 -o                           # Open in browser for the actual diff
+lore who src/features/auth/               # Who are the experts in this area?
+lore search "auth refactor" --type issue  # Related issues for background
+lore timeline "authentication"            # History of auth changes
+```
+
+**Gap identified:** No way to see the file list touched by an MR from the CLI (data is stored in `mr_file_changes` but not surfaced). No way to link an MR back to its closing issue(s) from the MR detail view. The cross-reference data exists in `entity_references` but isn't shown in `mrs <iid>` output.
+
+---
+
+### H5. Onboarding to an Unfamiliar Code Area
+
+**Problem:** "I'm new to the team and need to understand how the billing module works."
+
+**Flow:**
+```
+lore search "billing" -n 20               # What exists about billing?
+lore who src/billing/                      # Who knows billing best?
+lore timeline "billing" --depth 2         # History of billing changes
+lore mrs -s merged -l billing --since 6m  # Recent merged billing work
+lore issues -s opened -l billing          # Outstanding billing issues
+```
+
+**Gap identified:** No way to get a "module overview" in one command. The search spans issues, MRs, and discussions but doesn't summarize by category. No way to see the most-discussed or most-referenced entities (high-signal items for understanding).
+
+---
+
+### H6. Finding the Right Reviewer for My PR
+
+**Problem:** "I'm about to submit a PR touching auth and payments. Who should review?"
+
+**Flow:**
+```
+lore who src/features/auth/               # Auth experts
+lore who src/features/payments/           # Payment experts
+lore who @candidate1                      # Check candidate1's workload
+lore who @candidate2                      # Check candidate2's workload
+```
+
+**Gap identified:** No way to query multiple paths at once (`lore who src/auth/ src/payments/`). No way to find the intersection of expertise. No workload-aware recommendation ("who knows this AND has bandwidth"). Four separate commands for what should be one decision.
+
+---
+
+### H7. Understanding Why a Feature Was Built This Way
+
+**Problem:** "This code is weird. Why was it implemented like this? What was the original discussion?"
+
+**Flow:**
+```
+lore search "feature-name rationale"      # Search for decision context
+lore timeline "feature-name" --depth 2    # Full history with cross-refs
+lore issues 234                           # Read the original issue
+lore mrs 567                              # Read the implementation MR
+```
+
+**Gap identified:** No way to search within a specific issue's or MR's discussion notes. The search covers documents (titles + descriptions) but per-note search isn't available yet (PRD exists). No way to navigate "issue 234 was closed by MR 567" without manually knowing both IDs.
+
+---
+
+### H8. Checking Team Workload Before Assigning Work
+
+**Problem:** "I need to assign this urgent bug. Who has the least on their plate?"
+
+**Flow:**
+```
+lore who @alice                           # Alice's workload
+lore who @bob                             # Bob's workload
+lore who @carol                           # Carol's workload
+lore who @dave                            # Dave's workload
+```
+
+**Gap identified:** No team-level workload view. Must query each person individually. No way to list "all assignees and their open issue counts." No concept of a team roster. Would benefit from `lore who --team` or `lore workload`.
+
+---
+
+### H9. Preparing Release Notes
+
+**Problem:** "We're cutting a release. I need to summarize what's in this version."
+
+**Flow:**
+```
+lore mrs -s merged --since 2w -p myproject   # MRs merged since last release
+lore issues -s closed --since 2w -p myproject # Issues closed since last release
+lore mrs -s merged -l feature --since 2w      # Feature MRs specifically
+lore mrs -s merged -l bugfix --since 2w       # Bugfix MRs
+```
+
+**Gap identified:** No way to filter by milestone (for version-based releases). Wait -- `issues` has `-m` for milestone but `mrs` does not. No changelog generation. No "what closed between tag A and tag B." No grouping by label for release note categories.
+
+---
+
+### H10. Finding and Closing Stale Issues
+
+**Problem:** "Our backlog is bloated. Which issues haven't been touched in months?"
+
+**Flow:**
+```
+lore issues -s opened --sort updated --asc -n 50  # Oldest-updated first
+# Then manually inspect each one...
+lore issues 42                                      # Is this still relevant?
+```
+
+**Gap identified:** No `--before` or `--updated-before` filter (only `--since` exists). Can sort ascending but can't filter "not updated in 90 days." No staleness indicator. No bulk operations concept.
+
+---
+
+### H11. Understanding a Bug's Full History
+
+**Problem:** "Bug #321 keeps getting reopened. I need to understand its entire lifecycle."
+
+**Flow:**
+```
+lore issues 321                           # Read the issue
+lore timeline "bug-keyword" -p myproject  # Try to find timeline events
+# But timeline is keyword-based, not entity-based...
+```
+
+**Gap identified:** No way to get a timeline for a specific entity by IID. `lore timeline` requires a keyword query, not an entity reference. Would benefit from `lore timeline --issue 321` or `lore timeline --mr 456` to get the event history of a specific entity directly.
+
+---
+
+### H12. Identifying Who to Ask About Failing Tests
+
+**Problem:** "CI tests are failing in `src/lib/parser.rs`. Who last touched this?"
+
+**Flow:**
+```
+lore who src/lib/parser.rs                # Expert lookup
+lore who --overlap src/lib/parser.rs      # Who else has touched it
+lore search "parser" --type mr --since 2w # Recent MRs touching parser
+```
+
+**Gap identified:** Expert mode uses DiffNote analysis (code review comments), not actual file change tracking. The `mr_file_changes` table has the real data but `who` doesn't use it for attribution. Could be much more accurate with file-change-based expertise.
+
+---
+
+### H13. Tracking a Feature Across Multiple MRs
+
+**Problem:** "The 'dark mode' feature spans 5 MRs. I need to see them all together."
+
+**Flow:**
+```
+lore mrs -l dark-mode                     # MRs with the label
+lore issues -l dark-mode                  # Related issues
+lore timeline "dark mode" --depth 2       # Cross-referenced events
+```
+
+**Gap identified:** Works reasonably well with labels as the grouping mechanism. But if the team didn't label consistently, there's no way to discover related MRs by content similarity. No "related items" view that combines issues + MRs + discussions for a topic.
+
+---
+
+### H14. Checking if a Similar Fix Was Already Attempted
+
+**Problem:** "Before I implement this fix, was something similar tried before?"
+
+**Flow:**
+```
+lore search "memory leak connection pool" # Semantic search
+lore search "connection pool" --type mr -s all  # Wait, no state filter on search
+lore mrs -s closed -l bugfix              # Closed bugfix MRs (coarse)
+lore timeline "connection pool"           # Historical context
+```
+
+**Gap identified:** Search doesn't have a `--state` filter. Can't search only closed/merged items. The semantic search is powerful but can't be combined with entity state. Would benefit from `--state merged` on search to find past attempts.
+
+---
+
+### H15. Reviewing Discussions That Need My Attention
+
+**Problem:** "Which discussion threads am I involved in that are still unresolved?"
+
+**Flow:**
+```
+lore who --active                         # All active unresolved discussions
+lore who --active --since 30d             # Wider window
+# But can't filter to "discussions I'm in"...
+```
+
+**Gap identified:** `--active` shows all unresolved discussions, not filtered by participant. No way to say "show me discussions where @me participated." No notification/mention tracking. No "my unresolved threads" view.
+
+---
+
+## Part 2: AI Agent Flows
+
+### A1. Context Gathering Before Code Modification
+
+**Problem:** Agent is about to modify `src/features/auth/session.rs` and needs full context.
+
+**Flow:**
+```
+lore -J health                            # Pre-flight check
+lore -J who src/features/auth/            # Who knows this area
+lore -J search "auth session" -n 10       # Related issues/MRs
+lore -J mrs -s merged --since 3m -l auth  # Recent auth changes
+lore -J who --overlap src/features/auth/session.rs  # Concurrent work risk
+```
+
+**Gap identified:** No way to check "are there open MRs touching this file right now?" The overlap mode shows historical touches, not active branches. An agent needs to know about in-flight changes to avoid conflicts.
+
+---
+
+### A2. Auto-Triaging an Incoming Issue
+
+**Problem:** Agent receives a new issue and needs to categorize it, find related work, and suggest assignees.
+
+**Flow:**
+```
+lore -J issues 999                        # Read the new issue
+lore -J search "$(extract_keywords)" --explain  # Find similar past issues
+lore -J who src/affected/path/            # Suggest experts as assignees
+lore -J issues -s opened -l same-label    # Check for duplicates
+```
+
+**Gap identified:** No way to get just the description text for programmatic keyword extraction. `issues <iid>` returns full detail including discussions. Agent must parse the full response to extract the description for a secondary search. Would benefit from `--fields description` on detail view. No duplicate detection built in.
+
+---
+
+### A3. Generating Sprint Status Report
+
+**Problem:** Agent needs to produce a weekly status report for the team.
+
+**Flow:**
+```
+lore -J issues -s closed --since 1w --fields minimal  # Completed work
+lore -J issues -s opened --status "In progress"        # In-flight work
+lore -J mrs -s merged --since 1w --fields minimal      # Merged PRs
+lore -J mrs -s opened -D --fields minimal              # Open non-draft MRs
+lore -J count issues                                    # Totals
+lore -J count mrs                                       # MR totals
+lore -J who --active --since 1w                         # Discussions needing attention
+```
+
+**Gap identified:** Seven separate queries for one report. No `lore summary` or `lore report` command. No way to get "issues transitioned from X to Y this week" (state change history exists in events but isn't queryable). No velocity metric (issues closed per week trend).
+
+---
+
+### A4. Finding Relevant Prior Art Before Implementing
+
+**Problem:** Agent is implementing a caching layer and wants to find if similar patterns exist in the codebase's GitLab history.
+
+**Flow:**
+```
+lore -J search "caching" --mode hybrid -n 20 --explain
+lore -J search "cache invalidation" --mode hybrid -n 10
+lore -J search "redis" --mode lexical --type discussion   # Exact term in discussions
+lore -J timeline "cache" --since 1y                        # Wait, max is 1y? Let's try 12m
+```
+
+**Gap identified:** No way to search discussion notes individually (per-note search). Discussions are aggregated into documents, so individual note-level matches are lost. The `--explain` flag helps but doesn't show which specific note matched. No `--since 1y` or `--since 12m` duration format.
+
+---
+
+### A5. Building Context for PR Description
+
+**Problem:** Agent wrote code and needs to generate a PR description that references relevant issues.
+
+**Flow:**
+```
+lore -J search "feature description keywords" --type issue
+lore -J issues -s opened -l feature-label --fields iid,title,web_url
+# Cross-reference: which issues does this MR close?
+# No command for this -- must manually scan search results
+```
+
+**Gap identified:** No way to query the `entity_references` table directly. Agent can't ask "which issues reference MR !456" or "which issues contain 'closes #123' in their text." The data exists but isn't exposed as a query surface. Would benefit from `lore refs --mr 456` or `lore refs --issue 123`.
+
+---
+
+### A6. Identifying Affected Experts for Review Assignment
+
+**Problem:** Agent needs to automatically assign reviewers based on the files changed in an MR.
+
+**Flow:**
+```
+lore -J mrs 456                           # Get MR details
+# Parse file paths from response... but file changes aren't in the output
+lore -J who src/path/from/mr/             # Query each path
+lore -J who src/another/path/             # One at a time...
+lore -J who @candidate --fields minimal   # Check workload
+```
+
+**Gap identified:** MR detail view (`mrs <iid>`) doesn't include the file change list from `mr_file_changes`. Agent can't programmatically extract which files an MR touches. Must fall back to GitLab API or guess from description. The `who` command doesn't accept multiple paths. No "auto-reviewer" suggestion combining expertise + availability.
+
+---
+
+### A7. Incident Investigation and Timeline Reconstruction
+
+**Problem:** Agent needs to reconstruct what happened during an outage for a postmortem.
+
+**Flow:**
+```
+lore -J timeline "outage" --since 3d --depth 2 --expand-mentions
+lore -J search "error 500" --since 3d
+lore -J mrs -s merged --since 3d -p production-service
+lore -J issues --status "In progress" -p production-service
+```
+
+**Gap identified:** Timeline is keyword-seeded, which means if the outage wasn't described with that exact term, seeds may miss it. No way to seed a timeline from an entity ID (e.g., "start from issue #321 and expand outward"). No severity/priority filter. No way to correlate with merge times.
+
+---
+
+### A8. Cross-Project Impact Assessment
+
+**Problem:** Agent needs to understand how a breaking API change in project A affects projects B and C.
+
+**Flow:**
+```
+lore -J search "api-endpoint-name" -p project-a
+lore -J search "api-endpoint-name" -p project-b
+lore -J search "api-endpoint-name" -p project-c
+# Or without project filter to search everywhere:
+lore -J search "api-endpoint-name" -n 50
+lore -J timeline "api-endpoint-name" --depth 2
+```
+
+**Gap identified:** Cross-project references in entity_references are tracked but the timeline shows unresolved references for entities not synced locally. No way to see a cross-project dependency map. Search works across projects but doesn't group results by project.
+
+---
+
+### A9. Automated Stale Issue Recommendations
+
+**Problem:** Agent runs weekly to identify issues that should be closed or re-prioritized.
+
+**Flow:**
+```
+lore -J issues -s opened --sort updated --asc -n 100  # Oldest first
+# For each issue, check:
+lore -J issues <iid>                                    # Read details
+lore -J search "<issue title keywords>"                 # Any recent activity?
+```
+
+**Gap identified:** No `--updated-before` filter, so agent must fetch all and filter client-side. No way to detect "issue has no assignee AND no activity in 90 days." The 100-issue limit means pagination is needed for large backlogs, but there's no cursor/offset pagination -- only `--limit`. Agent must do N+1 queries to inspect each candidate.
+
+---
+
+### A10. Code Review Preparation (File-Level Context)
+
+**Problem:** Agent is reviewing MR !789 and needs to understand the history of each changed file.
+
+**Flow:**
+```
+lore -J mrs 789                           # Get MR details
+# Can't get file list from output...
+# Fall back to search by MR title keywords
+lore -J search "feature-from-mr" --type mr
+lore -J who src/guessed/path/             # Expertise for each file
+lore -J who --overlap src/guessed/path/   # Concurrent changes
+```
+
+**Gap identified:** Same as A6 -- `mr_file_changes` data isn't exposed. Agent is blind to the actual files in the MR unless it parses the description or uses the GitLab API directly. This is the single biggest gap for automated code review workflows.
+
+---
+
+### A11. Building a Knowledge Graph of Entity Relationships
+
+**Problem:** Agent wants to map how issues, MRs, and discussions are connected for a feature.
+
+**Flow:**
+```
+lore -J search "feature-name" -n 30
+lore -J timeline "feature-name" --depth 2 --max-entities 100
+# Timeline shows expanded entities and cross-refs, but...
+# No way to query entity_references directly
+# No way to get "all entities that reference issue #123"
+```
+
+**Gap identified:** The `entity_references` table (closes, related, mentioned) is used internally by timeline but isn't queryable as a standalone command. Agent can't ask "what closes issue #123?" or "what does MR !456 reference?" No graph export. Would enable powerful dependency mapping.
+
+---
+
+### A12. Release Readiness Assessment
+
+**Problem:** Agent needs to verify all issues in milestone "v2.0" are closed and MRs are merged.
+
+**Flow:**
+```
+lore -J issues -m "v2.0" -s opened       # Any open issues in milestone?
+lore -J issues -m "v2.0" -s closed       # Closed issues
+# MRs don't have milestone filter...
+lore -J mrs -s opened -l "v2.0"          # Try label as proxy
+lore -J who --active -p myproject        # Unresolved discussions
+```
+
+**Gap identified:** MRs don't have a `--milestone` filter (issues do). No way to check "all MRs linked to issues in milestone v2.0" -- would require joining `entity_references` with issue milestone. No release checklist concept. No way to verify "every issue in this milestone has a closing MR."
+
+---
+
+### A13. Answering "What Changed?" Between Two Points
+
+**Problem:** Agent needs to diff project state between two dates for a stakeholder report.
+
+**Flow:**
+```
+lore -J issues -s closed --since 2w --fields minimal    # Recently closed
+lore -J issues -s opened --since 2w --fields minimal    # Recently opened
+lore -J mrs -s merged --since 2w --fields minimal       # Recently merged
+# But no way to get "issues that CHANGED STATE" in a window
+# An issue opened 3 months ago but closed yesterday won't appear in --since 2w for issues -s opened
+```
+
+**Gap identified:** `--since` filters by `updated_at`, not by "state changed at." An issue closed yesterday but created 6 months ago would appear in `issues -s closed --since 1d` (because updated_at changed), but the semantics are subtle. No explicit "state transitions in time window" query. The resource_state_events table has this data but it's not exposed as a filter.
+
+---
+
+### A14. Meeting Prep: Summarize Recent Activity for a Stakeholder
+
+**Problem:** Agent needs to prepare a 2-minute summary for a project sponsor meeting.
+
+**Flow:**
+```
+lore -J count issues -p project           # Current totals
+lore -J count mrs -p project              # MR totals
+lore -J issues -s closed --since 1w -p project --fields minimal
+lore -J mrs -s merged --since 1w -p project --fields minimal
+lore -J issues -s opened --status "In progress" -p project
+lore -J who --active -p project --since 1w
+```
+
+**Gap identified:** Six queries, same as A3. No summary/dashboard command. Agent must synthesize all responses. No trend data (is the open issue count growing or shrinking?). No "highlights" extraction.
+
+---
+
+### A15. Determining If Work Is Safe to Start (Conflict Detection)
+
+**Problem:** Agent is about to start work on an issue and needs to check nobody else is already working on it.
+
+**Flow:**
+```
+lore -J issues 123                        # Read the issue
+# Check assignees from response
+lore -J mrs -s opened -A other-person     # Are they working on related MRs?
+lore -J who --overlap src/target/path/    # Anyone actively touching these files?
+lore -J search "issue-123-keywords" --type mr -s opened  # Wait, search has no --state
+```
+
+**Gap identified:** No way to check "is there an open MR that closes issue #123?" -- the entity_references data exists but isn't queryable. Search doesn't support `--state` filter. No "conflict detection" or "in-flight work" check. Agent must do multiple queries and manually correlate.
+
+---
+
+## Part 3: Gap Summary
+
+### Critical Gaps (high impact, blocks common workflows)
+
+| # | Gap | Affected Flows | Suggested Command/Flag |
+|---|-----|----------------|----------------------|
+| 1 | **MR file changes not surfaced** | H4, A6, A10 | `lore mrs <iid> --files` or include in detail view |
+| 2 | **Entity references not queryable** | H7, A5, A11, A15 | `lore refs --issue 123` / `lore refs --mr 456` |
+| 3 | **Per-note search missing** | H7, A4 | `lore search --granularity note` (PRD exists) |
+| 4 | **No entity-based timeline** | H11, A7 | `lore timeline --issue 321` / `lore timeline --mr 456` |
+| 5 | **No @me / current-user alias** | H1, H15 | Resolve from auth token automatically |
+
+### Important Gaps (significant friction, multiple workarounds needed)
+
+| # | Gap | Affected Flows | Suggested Command/Flag |
+|---|-----|----------------|----------------------|

+# plan-to-beads v2 — Draft for Review
+
+This is a draft of the improved skill. Review before applying to `~/.claude/skills/plan-to-beads/SKILL.md`.
+
+---
+
+```markdown
+---
+name: plan-to-beads
+description: Transforms markdown implementation plans into granular, agent-ready beads with dependency graphs. Each bead is fully self-contained — an agent can execute it with zero external context. Triggers on "break down this plan", "create beads from", "convert to beads", "make issues from plan".
+argument-hint: "[path/to/plan.md]"
+---
+
+# Plan to Beads Conversion
+
+## The Prime Directive
+
+**Every bead must be executable by an agent that has ONLY the bead description.** No plan document. No Slack context. No "see the PRD." The bead IS the spec. If an agent can't start coding within 60 seconds of reading the bead, it's not ready.
+
+## Workflow
+
+```
+┌──────────┐   ┌──────────┐   ┌──────────┐   ┌──────────┐   ┌──────────┐
+│ 1. PARSE │──▶│ 2. MINE  │──▶│ 3. BUILD │──▶│ 4. LINK  │──▶│ 5. AUDIT │
+│ Structure│   │ Context  │   │ Beads    │   │ Deps     │   │ Quality  │
+└──────────┘   └──────────┘   └──────────┘   └──────────┘   └──────────┘
+```
+
+### 1. Parse Structure
+
+Read the plan document. Identify:
+- **Epics**: Major sections / phases / milestones
+- **Tasks**: Implementable units with clear outcomes (1-4 hour scope)
+- **Subtasks**: Granular steps within tasks
+
+### 2. Mine Context
+
+This is the critical step. For EACH identified task, extract everything an implementing agent will need.
+
+#### From the plan document:
+
+| Extract | Where to look | Example |
+|---------|--------------|---------|
+| **Rationale** | Intro paragraphs, "why" sections | "We need this because the current approach causes N+1 queries" |
+| **Approach details** | Implementation notes, code snippets, architecture decisions | "Use a 5-stage pipeline: SEED → HYDRATE → ..." |
+| **Test requirements** | TDD sections, acceptance criteria, "verify by" notes | "Test that empty input returns empty vec" |
+| **Edge cases & risks** | Warnings, gotchas, "watch out for" notes | "Multi-byte UTF-8 chars can cause panics at byte boundaries" |
+| **Data shapes** | Type definitions, struct descriptions, API contracts | "TimelineEvent { kind: EventKind, timestamp: DateTime, ... }" |
+| **File paths** | Explicit mentions or inferable from module structure | "src/core/timeline_seed.rs" |
+| **Dependencies on other tasks** | "requires X", "after Y is done", "uses Z from step N" | "Consumes the TimelineEvent struct from the types task" |
+| **Verification commands** | Test commands, CLI invocations, expected outputs | "cargo test timeline_seed -- --nocapture" |
+
+#### From the codebase:
+
+Search the codebase to supplement what the plan says:
+- Find existing files mentioned or implied by the plan
+- Discover patterns the task should follow (e.g., how existing similar modules are structured)
+- Check test files for naming conventions and test infrastructure in use
+- Confirm exact file paths rather than guessing
+
+Use codebase search tools (WarpGrep, Explore agent, or targeted Grep/Glob) appropriate to the scope of what you need to find.
+
+### 3. Build Beads
+
+Use `br` exclusively.
+
+| Type | Priority | Command |
+|------|----------|---------|
+| Epic | 1 | `br create "Epic: [Title]" -p 1` |
+| Task | 2-3 | `br create "[Verb] [Object]" -p 2` |
+| Subtask | 3-4 | `br q "[Verb] [Object]"` |
+
+**Granularity target**: Each bead completable in 1-4 hours by one agent.
+
+#### Description Templates
+
+Use the **full template** for all task-level beads. Use the **light template** only for trivially small tasks (config change, single-line fix, add a re-export).
+
+##### Full Template (default)
+
+```
+## Background
+[WHY this exists. What problem it solves. How it fits into the larger system.
+Include enough context that an agent unfamiliar with the project understands
+the purpose. Reference architectural patterns in use.]
+
+## Approach
+[HOW to implement. Be specific:
+- Data structures / types to create or use (include field names and types)
+- Algorithms or patterns to follow
+- Code snippets from the plan if available
+- Which existing code to reference for patterns (exact file paths)]
+
+## Acceptance Criteria
+
+### Specified (from plan — implement as-is)
+- [ ] <criteria explicitly stated in the plan>
+- [ ] <criteria explicitly stated in the plan>
+
+### Proposed (inferred — confirm with user before implementing) [?]
+- [ ] [?] <criteria the agent inferred but the plan didn't specify>
+- [ ] [?] <criteria the agent inferred but the plan didn't specify>
+
+**ASSUMPTION RULE**: If proposed criteria exceed ~30% of total, STOP.
+The bead needs human input before it's ready for implementation. Flag it
+in the audit output and ask the user to refine the ACs.
+
+## Files
+[Exact paths to create or modify. Confirmed by searching the codebase.]
+- CREATE: src/foo/bar.rs
+- MODIFY: src/foo/mod.rs (add pub mod bar)
+- MODIFY: tests/foo_tests.rs (add test module)
+
+## TDD Anchor
+[The first test to write. This grounds the agent's work.]
+RED: Write `test_<name>` in `<test_file>` that asserts <specific behavior>.
+GREEN: Implement the minimal code to make it pass.
+VERIFY: <project's test command> <pattern>
+
+[If the plan specifies additional tests, list them all:]
+- test_empty_input_returns_empty_vec
+- test_single_issue_produces_one_event
+- test_handles_missing_fields_gracefully
+
+## Edge Cases
+[Gotchas, risks, things that aren't obvious. Pulled from the plan's warnings,
+known issues, or your analysis of the approach.]
+- <edge case 1>
+- <edge case 2>
+
+## Dependency Context
+[For each dependency, explain WHAT it provides that this bead consumes.
+Not just "depends on bd-xyz" but "uses the `TimelineEvent` struct and
+`SeedConfig` type defined in bd-xyz".]
+```
+
+##### Light Template (trivially small tasks only)
+
+Use this ONLY when the task is a one-liner or pure mechanical change (add a re-export, flip a config flag, rename a constant). If there's any ambiguity about approach, use the full template.
+
+```
+## What
+[One sentence: what to do and where.]
+
+## Acceptance Criteria
+- [ ] <single binary criterion>
+
+## Files
+- MODIFY: <exact path>
+```
+
+### 4. Link Dependencies
+
+```bash
+br dep add [blocker-id] [blocked-id]
+```
+
+Dependency patterns:
+- Types/structs → code that uses them
+- Infrastructure (DB, config) → features that need them
+- Core logic → extensions/enhancements
+- Tests may depend on test helpers
+
+**Critical**: When linking deps, update the "Dependency Context" section in the blocked bead to describe exactly what it receives from the blocker.
+
+### 5. Audit Quality
+
+Before reporting, review EVERY bead against this checklist:
+
+| Check | Pass criteria |
+|-------|--------------|
+| **Self-contained?** | Agent can start coding in 60 seconds with ONLY this description |
+| **TDD anchor?** | First test to write is named and described |
+| **Binary criteria?** | Every acceptance criterion is pass/fail, not subjective |
+| **Exact paths?** | File paths verified against codebase, not guessed |
+| **Edge cases?** | At least 1 non-obvious gotcha identified |
+| **Dep context?** | Each dependency explains WHAT it provides, not just its ID |
+| **Approach specifics?** | Types, field names, patterns — not "implement the thing" |
+| **Assumption budget?** | Proposed [?] criteria are <30% of total ACs |
+
+If a bead fails any check, fix it before moving on. If the assumption budget is exceeded, flag the bead for human review rather than inventing more ACs.
+
+## Assumption & AC Guidance
+
+Agents filling in beads will inevitably encounter gaps in the plan. The rules:
+
+1. **Never silently fill gaps.** If the plan doesn't specify a behavior, don't assume one and bury it in the ACs. Mark it `[?]` so the implementing agent knows to ask.
+
+2. **Specify provenance on every AC.** Specified = from the plan. Proposed = your inference. The implementing agent treats these differently:
+   - **Specified**: implement without question
+   - **Proposed [?]**: pause and confirm with the user before implementing
+
+3. **The 30% rule.** If more than ~30% of ACs on a bead are proposed/inferred, the plan was too vague for this task. Don't create the bead as-is. Instead:
+   - Create it with status noting "needs AC refinement"
+   - List the open questions explicitly
+   - Flag it in the output report under "Beads Needing Human Input"
+
+4. **Prefer smaller scope over more assumptions.** If you're unsure whether a task should handle edge case X, make the bead's scope explicitly exclude it and note it as a potential follow-up. A bead that does less but does it right beats one that guesses wrong.
+
+5. **Implementing agents: honor the markers.** When you encounter `[?]` on an AC, you MUST ask the user before implementing that behavior. Do not silently resolve it in either direction.
+
+## Output Format
+
+After completion, report:
+
+```
+## Beads Created: N total (X epics, Y tasks, Z subtasks)
+
+### Quality Audit
+- Beads scoring 4+: N/N (target: 100%)
+- [list any beads that needed extra attention and why]
+
+### Beads Needing Human Input
+[List any beads where proposed ACs exceeded 30%, or where significant
+ambiguity in the plan made self-contained descriptions impossible.
+Include the specific open questions for each.]
+
+### Critical Path
+[blocker] → [blocked] → [blocked]
+
+### Ready to Start
+- bd-xxx: [Title] — [one-line summary of what agent will do]
+- bd-yyy: [Title] — [one-line summary of what agent will do]
+
+### Dependency Graph
+[Brief visualization or description of the dep structure]
+```
+
+## Risk Tiers
+
+| Operation | Tier | Behavior |
+|-----------|------|----------|
+| `br create` | SAFE | Auto-proceed |
+| `br dep add` | SAFE | Auto-proceed |
+| `br update --description` | CAUTION | Verify content |
+| Bulk creation (>20 beads) | CAUTION | Confirm count first |
+
+## Anti-Patterns
+
+| Anti-Pattern | Why it's bad | Fix |
+|-------------|-------------|-----|
+| "Implement the pipeline stage" | Agent doesn't know WHAT to implement | Name the types, the function signatures, the test |
+| "See plan for details" | Plan isn't available to the agent | Copy the relevant details INTO the bead |
+| "Files: probably src/foo/" | Agent wastes time finding the right file | Search the codebase, confirm exact paths |
+| "Should work correctly" | Not binary, not testable | "test_x passes" or "output matches Y" |
+| No TDD anchor | Agent doesn't know where to start | Always specify the first test to write |
+| "Depends on bd-xyz" (without context) | Agent doesn't know what bd-xyz provides | "Uses FooStruct and bar() function from bd-xyz" |
+| Single-line description | Score 1 bead, agent is stuck | Use the full template, every section |
+| Silently invented ACs | User surprised by implementation choices | Mark inferred ACs with [?], honor the 30% rule |

+I avoided everything already listed in your `Rejected Ideas` section and focused on net-new upgrades.
+
+1. Centralize MR temporal semantics in one `mr_activity` CTE (architecture + correctness)
+Why this improves the plan: right now the state-aware timestamp logic is repeated across multiple signal branches, while `closed_mr_multiplier` is applied later in Rust by string state checks. That split is brittle. A single `mr_activity` CTE removes drift risk, simplifies query maintenance, and avoids per-row state-string handling in Rust.
+

+
+2. Parameterize `reviewer_min_note_chars` and tighten config validation (robustness)
+Why this improves the plan: inlining `reviewer_min_note_chars` into SQL text creates statement-cache churn and avoidable SQL-text variability. Also, current validation misses finite-range guards (`NaN`, absurd half-lives). Parameterization + stronger validation reduces weird failure modes.
+
+```diff

+```
+
+3. Add path canonicalization before probes/scoring (correctness + UX)
+Why this improves the plan: rename-awareness helps only after path resolution succeeds. Inputs like `./src//foo.rs` or inconsistent trailing slashes can still miss. Canonicalizing query paths up front reduces false negatives and ambiguous suffix behavior.
+
+```diff
+diff --git a/plan.md b/plan.md
+@@ 3a. Path Resolution Probes (who.rs)
++Add `normalize_query_path()` before `build_path_query()`:
++- strip leading `./`
++- collapse repeated `/`
++- trim whitespace
++- preserve trailing `/` only for explicit prefix intent
++Expose both `path_input_original` and `path_input_normalized` in `resolved_input`.
+@@ New Tests
++test_path_normalization_handles_dot_and_double_slash
++test_path_normalization_preserves_explicit_prefix_semantics
+```
+
+4. Add epsilon-based tie buckets for stable ranking (determinism)
+Why this improves the plan: even with deterministic summation order, tiny `powf` platform differences can reorder near-equal scores. Tie bucketing keeps ordering stable and user-meaningful.
+
+```diff
+diff --git a/plan.md b/plan.md
+@@ 4. Rust-Side Aggregation (who.rs)
+-Sort on raw `f64` score — `(raw_score DESC, last_seen DESC, username ASC)`.
++Sort using a tie bucket:
++`score_bucket = (raw_score / 1e-9).floor() as i64`
++Order by `(score_bucket DESC, raw_score DESC, last_seen DESC, username ASC)`.
++This preserves precision while preventing meaningless micro-delta reorderings.
+@@ New Tests
++test_near_equal_scores_use_stable_tie_bucket_order
+```
+
+5. Add `--diagnose-score` aggregated diagnostics (operability)
+Why this improves the plan: `--explain-score` tells “why this user scored”, but not “why this query behaved oddly” (path ambiguity, dedup collapse, old_path contribution share, filtered bots, window exclusions). Lightweight aggregate diagnostics are high-value without per-MR drill-down complexity.
+
+```diff
+diff --git a/plan.md b/plan.md
+@@ CLI changes (who.rs)
++Add `--diagnose-score` flag (compatible with `--explain-score`, incompatible with `--detail`).

++- matched_file_changes_raw_count
++- matched_file_changes_dedup_count
++- rows_excluded_by_window_upper_bound
++- users_filtered_by_excluded_usernames
++- query_elapsed_ms
+@@ Robot output
++`diagnostics` object emitted only when `--diagnose-score` is set.
+```
+
+6. Add probe-optimized indexes for path resolution (performance)
+Why this improves the plan: current proposed indexes are optimized for scoring joins, but `build_path_query()` and `suffix_probe()` run existence/path-only probes where `author_username` is not constrained. Dedicated probe indexes will materially reduce latency for path lookup modes.
+
+```diff
+diff --git a/plan.md b/plan.md
+@@ 6. Index Migration (db.rs)
++-- Fast exact/prefix/suffix path probes on notes (no author predicate)
++CREATE INDEX IF NOT EXISTS idx_notes_new_path_project_created
++  ON notes(position_new_path, project_id, created_at)
++  WHERE note_type = 'DiffNote' AND is_system = 0 AND position_new_path IS NOT NULL;
++
++CREATE INDEX IF NOT EXISTS idx_notes_old_path_project_created
++  ON notes(position_old_path, project_id, created_at)
++  WHERE note_type = 'DiffNote' AND is_system = 0 AND position_old_path IS NOT NULL;
+```
+
+7. Add multi-path expert scoring (`--path` repeatable) with dedup across paths (feature + utility)
+Why this improves the plan: current model is single-path centric. Real ownership questions are usually subsystem-level. Repeatable paths/prefixes let users ask “who knows auth stack?” in one call. Dedup by `(username, signal, mr_id)` avoids double-counting same MR touching multiple requested paths.
+
+```diff
+diff --git a/plan.md b/plan.md
+@@ CLI/feature scope
++Add repeatable `--path` in expert mode:
++`lore who --expert --path src/auth/ --path src/session/`
++Optional `--path-file <file>` for large path sets (one per line).
+@@ SQL Restructure
++Add `requested_paths` CTE and match each source against that set.
++Ensure dedup key includes `(username, signal, mr_id)` so one MR contributes once per signal even if multiple paths match.
+@@ New Tests
++test_multi_path_query_unions_results_without_double_counting
++test_multi_path_with_overlap_prefixes_is_idempotent
+```
+
+These 7 revisions keep your current model direction intact, but reduce correctness drift risk, harden edge handling, improve query observability, and make the feature materially more useful for real ownership workflows.

 **Rationale for CTE-based dual-path matching**: The previous approach (repeating `OR old_path` in every signal subquery) duplicated the path matching logic 5 times. Factoring it into foundational CTEs (`matched_notes_raw` → `matched_notes`, `matched_file_changes_raw` → `matched_file_changes`) means path matching is defined once, each index branch is explicit, and adding future path resolution logic (e.g., alias chains) only requires changes in one place. The UNION ALL + dedup pattern ensures SQLite uses the optimal index for each path column independently.

+**Rationale for `mr_activity` CTE**: The previous approach repeated the state-aware CASE expression and `m.state` column in signals 3, 4a, and 4b, with the `closed_mr_multiplier` applied later in Rust by string-matching on `mr_state`. This split was brittle — the CASE expression could drift between signal branches, and per-row state-string handling in Rust was unnecessary indirection. The `mr_activity` CTE defines the timestamp and multiplier once, scoped to matched MRs only (via JOIN with `matched_file_changes`) to avoid materializing the full MR table. Signals 3, 4a, 4b now reference `a.activity_ts` and `a.state_mult` directly. Signals 1 and 2 (DiffNote-based) still compute `state_mult` inline because they join through `discussions`, not `matched_file_changes`, and adding them to `mr_activity` would require a second join path that doesn't simplify anything.
+
+**Rationale for parameterized `reviewer_min_note_chars` and `closed_mr_multiplier`**: Previous iterations inlined `reviewer_min_note_chars` as a literal in the SQL string and kept `closed_mr_multiplier` in Rust only. Binding both as SQL parameters (`?5` for `closed_mr_multiplier`, `?6` for `reviewer_min_note_chars`) eliminates statement-cache churn (the SQL text is identical regardless of config values), avoids SQL-text variability that complicates EXPLAIN QUERY PLAN analysis, and centralizes the multiplier application in SQL for file-change signals. The DiffNote signals (1, 2) still compute `state_mult` inline because they don't go through `mr_activity`.
+
+### 3a. Path Canonicalization and Resolution Probes (who.rs)
+
+**Path canonicalization**: Before any path resolution or scoring, normalize the user's input path via `normalize_query_path()`:
+- Strip leading `./` (e.g., `./src/foo.rs` → `src/foo.rs`)
+- Collapse repeated `/` (e.g., `src//foo.rs` → `src/foo.rs`)
+- Trim leading/trailing whitespace
+- Preserve trailing `/` only when present — it signals explicit prefix intent
+
+This is applied once at the top of `run_who()` before `build_path_query()`. The robot JSON `resolved_input` includes both `path_input_original` (raw user input) and `path_input_normalized` (after canonicalization) for debugging transparency. The normalization is purely syntactic — no filesystem lookups, no canonicalization against the database.
+
+**Path resolution probes**: Rename awareness must extend beyond scoring queries to the path resolution layer. Currently `build_path_query()` (line 457) and `suffix_probe()` (line 584) only check `position_new_path` and `new_path`. If a user queries an old path name, these probes return "not found" and the scoring query never runs.

-**State-aware timestamps for file-change signals (signals 3, 4a, 4b)**: Replace `m.updated_at` with a state-aware expression:
+**State-aware timestamps for file-change signals (signals 3, 4a, 4b)**: Centralized in the `mr_activity` CTE (see section 3). The CASE expression uses `merged_at` for merged MRs, `closed_at` for closed MRs, and `updated_at` for open MRs, with `created_at` as fallback when the preferred timestamp is NULL.
-
-```sql
-CASE
-  WHEN m.state = 'merged' THEN COALESCE(m.merged_at, m.created_at)
-  WHEN m.state = 'closed' THEN COALESCE(m.closed_at, m.created_at)
-  ELSE COALESCE(m.updated_at, m.created_at)  -- opened / other
-END AS activity_ts
-```
 
 **Rationale**: `updated_at` is noisy for merged MRs — it changes on label edits, title changes, rebases, and metadata touches, creating false recency. `merged_at` is the best indicator of when code expertise was formed (the moment the code entered the branch). But for **open MRs**, `updated_at` is actually the right signal because it reflects ongoing active work. `closed_at` anchors closed-without-merge MRs to their closure time (these represent review effort even if the code was abandoned). Each state gets the timestamp that best represents when expertise was last exercised.

-- **Notes per MR**: `HashMap<i64, (u32, i64, String)>` (mr_id -> (count, max_ts, mr_state)) from `note_group` rows in the aggregated query (already grouped per user+MR with note_count in `qty`). Used for `log2(1 + count)` diminishing returns.

 **Why include closed MRs?** A closed-without-merge MR still represents review effort and code familiarity — the reviewer read the diff, left comments, and engaged with the code even though it was ultimately abandoned. Excluding closed MRs entirely (the previous plan's approach) discarded this signal. The `closed_mr_multiplier` (default 0.5) halves the contribution, reflecting that the code never landed but the reviewer's cognitive engagement was real. This also eliminates the dead-code inconsistency where the state-aware CASE expression handled `closed` but the WHERE clause excluded it.

This was brittle — the CASE could drift between branches and the Rust-side string matching was unnecessary indirection.

+- **Path canonicalization via `normalize_query_path()`**: Inputs like `./src//foo.rs` or whitespace-padded paths could fail path resolution even when the file exists in the database. A simple syntactic normalization (strip `./`, collapse `//`, trim whitespace, preserve trailing `/`) runs before `build_path_query()` to reduce false negatives. No filesystem or database lookups — purely string manipulation.

At the scale of dozens to low hundreds of contributions per user, the rounding error from naive f64 summation is on the order of 1e-14 — several orders of magnitude below any meaningful score difference. Compensated summation adds code complexity and a maintenance burden for no practical benefit at this scale.
 - **Automated CI benchmark gate** (feedback-5 #10 partial): Accepted manual performance baselines, but rejected automated CI regression gating with synthetic fixtures (100k/1M/5M notes). Building and maintaining benchmark infrastructure is a significant investment that's premature for a CLI tool with ~3 users. Manual timing checks during development are sufficient until performance becomes a real concern.
+- **Epsilon-based tie buckets for ranking** (feedback-6 #4) — rejected because the plan already has deterministic contribution ordering by `mr_id` within each signal type, which eliminates HashMap-iteration nondeterminism. Platform-dependent `powf` differences at the scale of dozens to hundreds of contributions per user are sub-epsilon (order of 1e-15). If two users genuinely score within 1e-9 of each other, the existing tiebreak by `(last_seen DESC, username ASC)` is already meaningful and deterministic. Adding a bucketing layer introduces a magic epsilon constant and floor operation for a problem that doesn't manifest in practice.
+- **`--diagnose-score` aggregated diagnostics flag** (feedback-6 #5) — rejected because this is diagnostic/debugging tooling that adds a new flag, new output format, and new counting logic (matched_notes_raw_count, dedup_count, window exclusions, etc.) across the SQL pipeline. The existing `--explain-score` component breakdown + manual EXPLAIN QUERY PLAN verification already covers the debugging need. The additional SQL instrumentation required (counting rows at each CTE stage) would complicate the query for a feature with unclear demand. A v2 addition if operational debugging becomes a recurring need.
+- **Multi-path expert scoring (`--path` repeatable)** (feedback-6 #7) — rejected because this is a feature expansion, not a plan improvement for the time-decay model. Multi-path requires a `requested_paths` CTE, modified dedup logic keyed on `(username, signal, mr_id)` across paths, CLI parsing changes for repeatable `--path` and `--path-file`, and new test cases for overlap/prefix/dedup semantics. This is a separate bead/feature that should be designed independently — it's orthogonal to time-decay scoring and can be added later without requiring any changes to the decay model.

+I found 9 high-impact revisions that materially improve correctness, robustness, and usability without reintroducing anything in `## Rejected Recommendations`.
+
+### 1. Prevent stale async overwrites on **all** screens (not just search)
+Right now, only `SearchExecuted` is generation-guarded. `IssueListLoaded`, `MrListLoaded`, `IssueDetailLoaded`, etc. can still race and overwrite newer state after rapid navigation/filtering. This is the biggest correctness risk in the current design.
+
+```diff

+                 Cmd::none()
+             }
+```
+
+### 2. Make cancellation safe with task-owned SQLite interrupt handles
+The plan mentions `sqlite3_interrupt()` but uses pooled shared reader connections. Interrupting a shared connection can cancel unrelated work. Use per-task reader leases and store `InterruptHandle` in `TaskHandle`.
+
+```diff
+diff --git a/PRD.md b/PRD.md
+@@ DbManager
+-    readers: Vec<Mutex<Connection>>,
++    readers: Vec<Mutex<Connection>>,
++    // task-scoped interrupt handles prevent cross-task cancellation bleed

++    pub interrupt: Option<rusqlite::InterruptHandle>,
+ }
+
+@@ cancellation
+-Query interruption: ... fires sqlite3_interrupt() on the connection.
++Query interruption: cancel triggers the task's owned InterruptHandle only.
++No shared-connection interrupt is permitted.
+```
+
+### 3. Harden keyset pagination for multi-project and sort changes
+`updated_at + iid` cursor is not enough when rows share timestamps across projects or sort mode changes. This can duplicate/skip rows.
+
+```diff
+diff --git a/PRD.md b/PRD.md
+@@ issue_list.rs
+-pub struct IssueCursor {
+-    pub updated_at: i64,

++    pub iid: i64,
++    pub project_id: i64,   // deterministic tie-breaker
++    pub filter_hash: u64,  // invalidates stale cursors on filter mutation
++}
+
+@@ pagination section
+-Windowed keyset pagination ...
++Windowed keyset pagination uses deterministic tuple ordering:
++`ORDER BY <primary_sort>, project_id, iid`.
++Cursor is rejected if `filter_hash` or sort tuple mismatches current query.
+```
+
+### 4. Replace ad-hoc filter parsing with a small typed DSL
+Current `split_whitespace()` parser is brittle and silently lossy. Add quoted values, negation, and strict parse errors.
+
+```diff
+diff --git a/PRD.md b/PRD.md
+@@ filter_bar.rs
+-    fn parse_tokens(&mut self) {
+-        let text = self.input.value().to_string();
+-        self.tokens = text.split_whitespace().map(|chunk| { ... }).collect();
+-    }
++    fn parse_tokens(&mut self) {
++        // grammar (v1):
++        // term := [ "-" ] (field ":" value | quoted_text | bare_text)
++        // value := quoted | unquoted
++        // examples:
++        //   state:opened label:"P1 blocker" -author:bot since:14d
++        self.tokens = filter_dsl::parse(self.input.value())?;
++    }
+
+@@ section 8 / keybindings-help
++Filter parser surfaces actionable inline diagnostics with cursor position,
++and never silently drops unknown fields.
+```
+
+### 5. Add render caches for markdown/tree shaping
+Markdown and tree shaping are currently recomputed on every frame in several snippets. Cache render artifacts by `(entity, width, theme, content_hash)` to protect frame time.
+
+```diff
+diff --git a/PRD.md b/PRD.md
+@@ module structure
++    render_cache.rs               # Width/theme/content-hash keyed cache for markdown + tree layouts
+
+@@ Assumptions / Performance
++Detail and search preview rendering uses memoized render artifacts.
++Cache invalidation triggers: content hash change, terminal width change, theme change.
+```
+
+### 6. Use one-shot timers for debounce/prefix timeout
+`Every` is periodic; it wakes repeatedly and can produce edge-case repeated firings. One-shot subscriptions are cleaner and cheaper.
+
+```diff
+diff --git a/PRD.md b/PRD.md
+@@ subscriptions()
+-        if self.state.search.debounce_pending() {
+-            subs.push(Box::new(

++GoPrefix timeout is a one-shot `After(500ms)` tied to prefix generation.
+```
+
+### 7. New feature: list “Quick Peek” panel (`Space`) for triage speed
+This adds immediate value without v2-level scope. Users can inspect selected issue/MR metadata/snippet without entering detail and coming back.
+
+```diff

+
+### 8. Upgrade compatibility handshake from integer to machine-readable contract
+Single integer compat is too coarse for real drift detection. Keep it simple but structured.

+I reviewed the full PRD and avoided everything listed under `## Rejected Recommendations`.  
+These are the highest-impact revisions I’d make.
+
+1. Stable list pagination via snapshot fences
+Why this improves the plan: your keyset cursor is deterministic for sort/filter, but still vulnerable to duplicates/skips if sync writes land between page fetches. Add a per-browse snapshot fence so one browse session sees a stable dataset.
+Tradeoff: newest rows are hidden until refresh, which is correct for deterministic triage.
+
+```diff

++ or skipped rows during scrolling even if sync writes occur concurrently.
++ A "new data available" badge appears when a newer sync completes; `r` refreshes the fence.

+@@ 4.7 Navigation Stack Implementation
++ Browsing sessions carry a per-screen `BrowseSnapshot` token to preserve stable ordering
++ until explicit refresh or screen re-entry.
+```
+
+2. Query budgets and soft deadlines
+Why this improves the plan: currently “slow query” is handled mostly by cancellation and stale-drop. Add explicit latency budgets so UI responsiveness stays predictable under worst-case filters.
+Tradeoff: sometimes user gets partial/truncated results first, followed by full results on retry/refine.
+
+```diff

++ Each query type gets a budget:
++ - list window fetch: 120ms target, 250ms hard deadline
++ - detail phase-1 metadata: 75ms target, 150ms hard deadline
++ - search lexical/hybrid: 250ms hard deadline
++ On hard deadline breach, return `QueryDegraded { truncated: true }` and show inline badge:
++ "results truncated; refine filter or press r to retry full".
++ Implementation uses SQLite progress handler + per-task interrupt deadline.
+
+@@ 9.3 Phase 0 — Toolchain Gate
++ 26. Query deadline behavior validated: hard deadline cancels query and renders degraded badge
++ without blocking input loop.
+```
+
+3. Targeted cache invalidation and prewarm after sync
+Why this improves the plan: `invalidate_all()` after sync throws away hot detail cache and hurts the exact post-sync workflow you optimized for. Invalidate only changed keys and prewarm likely-next entities.
+Tradeoff: slightly more bookkeeping in sync result handling.
+
+```diff

++                self.enqueue_cache_prewarm(&result.changed_entity_keys);
+```
+
+4. Exact “what changed” navigation without new DB tables
+Why this improves the plan: your summary currently uses timestamp filter; this can include unrelated updates and miss edge cases. Keep an in-memory delta ledger per sync run and navigate by exact IDs.
+Tradeoff: small memory overhead per run; no schema migration required.
+
+```diff

+
+5. Adaptive render governor (runtime performance safety)
+Why this improves the plan: capability detection is static; you also need dynamic adaptation when frame time/backpressure worsens (SSH, tmux nesting, huge logs).
+Tradeoff: visual richness may step down automatically under load.
+
+```diff

++stays within p95 < 75ms while auto-downgrading render profile.
+```
+
+6. First-run/data-not-ready screen (not an init wizard)
+Why this improves the plan: empty DB or missing indexes will otherwise feel broken. A dedicated read-only readiness screen improves first impression and self-recovery.
+Tradeoff: one extra lightweight screen/state.

+```
+
+7. Global project scope pinning across screens
+Why this improves the plan: users repeatedly apply the same project filter across dashboard/list/search/timeline/who. Add a global scope pin to reduce repetitive filtering and speed triage.
+Tradeoff: must show clear “scope active” indicator to avoid confusion.
+

+
+8. Concurrency correctness tests for pagination and cancellation races
+Why this improves the plan: current reliability tests are good, but missing a direct test for duplicate/skip behavior under concurrent sync writes while paginating.
+Tradeoff: additional integration test complexity.
+
+```diff

+@@ 9.3 Phase 0 — Toolchain Gate
++28. Concurrent pagination/write test proves no duplicates/skips within a pinned browse snapshot.
++29. Cancellation race test proves no cross-task interrupt bleed and no stuck loading state.
+```
+
+9. URL opening policy v2: allowlisted GitLab entity paths
+Why this improves the plan: host validation is necessary but not always sufficient. Restrict default browser opens to known GitLab entity paths and require confirmation for unusual paths on same host.
+Tradeoff: occasional extra prompt for uncommon but valid URLs.
+
+```diff
+diff --git a/docs/plans/gitlore-tui-prd-v2.md b/docs/plans/gitlore-tui-prd-v2.md

++ pub fn classify_safe_url(url: &str, policy: &UrlPolicy) -> UrlSafety
++ // UrlSafety::{AllowedEntityPath, AllowedButUnrecognizedPath, Blocked}
+```
+
+These 9 changes are additive, avoid previously rejected ideas, and materially improve determinism, responsiveness, post-sync usefulness, and safety without forcing a big architecture reset.

+**Filtering:** Interactive filter bar with typed DSL parser. Grammar (v1):
+- `term := [ "-" ] (field ":" value | quoted_text | bare_text)`
+- `value := quoted | unquoted`
+- Examples: `state:opened label:"P1 blocker" -author:bot since:14d`
+- Negation prefix (`-`) excludes matches for that term
+- Quoted values allow spaces in filter values
+- Parser surfaces inline diagnostics with cursor position for parse errors — never silently drops unknown fields
 **Pagination:** Windowed keyset pagination with explicit cursor state. The list state maintains `window` (current visible rows), `next_cursor` / `prev_cursor` (keyset boundary values for forward/back navigation), `prefetching` flag (background fetch of next window in progress), and a fixed `window_size` (default 200 rows). First paint uses current window only; no full-result materialization. Virtual scrolling within the window for smooth UX. When the user scrolls past ~80% of the window, the next window is prefetched in the background.
 
+**Snapshot fence:** On list entry, capture `snapshot_upper_updated_at` (current max `updated_at` in the result set) and pin all list-page queries to `updated_at <= snapshot_upper_updated_at`. This guarantees no duplicate or skipped rows during scrolling even if sync writes occur concurrently. A "new data available" badge appears when a newer sync completes; `r` refreshes the fence and re-queries from the top.

+**Quick Peek (`Space`):** Toggle a right-side preview pane showing the selected item's metadata, first discussion snippet, and cross-references without entering the full detail view. This enables rapid triage scanning — the user can evaluate issues at a glance without the Enter/Esc cycle. The peek pane uses the same progressive hydration as detail views (metadata first, discussions lazy). The pane width adapts to terminal breakpoints (hidden at Xs/Sm, 40% width at Md+).
+
+**Cursor determinism:** Keyset pagination uses deterministic tuple ordering: `ORDER BY <primary_sort>, project_id, iid`. The cursor struct includes the current `sort_field`, `sort_order`, `project_id` (tie-breaker for multi-project datasets where rows share timestamps), and a `filter_hash: u64` (hash of the active filter state). On cursor resume, the cursor is rejected if `filter_hash` or sort tuple mismatches the current query — this prevents stale cursors from producing duplicate/skipped rows after the user changes sort mode or filters mid-browse.

 **Performance SLO rationale:** Interactive TUI responsiveness requires sub-100ms for list operations and sub-250ms for search. Tiered fixtures catch scaling regressions at different data magnitudes — a query that's fast at 10k rows may degrade at 100k without proper indexing or pagination. Memory ceilings prevent unbounded growth from large in-memory result sets. These targets are validated with synthetic SQLite fixtures during Phase 0 and enforced as CI benchmark gates thereafter. Required indexes are documented and migration-backed before TUI GA.

 - **Search Facets panel (entity type counts, top labels/projects/authors with one-key apply)** — rejected as feature scope expansion for v1. The concept (three-pane layout with facet counts and quick-apply shortcuts like `1/2/3` for type facets, `l` for label cycling) is compelling and would make search more actionable for triage workflows. However, it requires: new aggregate queries for facet counting that must perform well across all three data tiers, a third layout pane that breaks the current two-pane split design, new keybinding slots (`1/2/3/l`) that could conflict with future list navigation, and per-query facet recalculation that adds latency. The existing search with explicit field-based filters is sufficient for v1. Facets are a strong v2 candidate — once search has production mileage and users report wanting faster triage filtering, the aggregate query patterns and UI layout can be designed with real usage data.

+Recommendations from external review (feedback-10, ChatGPT) that were evaluated and declined:
+
+- **Structured compat handshake (`--compat-json` replacing `--compat-version` integer)** — rejected because the current two-step contract (integer compat version + separate schema version check) is intentionally minimal and robust. Adding JSON parsing (`{ "protocol": 1, "compat_version": 2, "min_schema": 14, "max_schema": 16, "build": "..." }`) to a preflight binary validation introduces a new failure mode (malformed JSON, missing fields, version parsing) for zero user-visible benefit. The integer check detects "too old to work" — the only case that matters before spawning the TUI. Schema range is already validated separately via `--check-schema`. Combining both into a single JSON response couples concerns that are better kept independent (binary compat vs schema compat). The current approach is more resilient: if `--compat-version` is missing (old binary), we warn and proceed; JSON parsing failure would be a hard error. KISS principle applies.
+
+Recommendations from external review (feedback-11, ChatGPT) that were evaluated and declined:
+
+- **Query budgets and soft deadlines (120ms/250ms hard deadlines with `QueryDegraded` truncation)** — rejected as over-engineering for a local SQLite tool. The proposal adds per-query-type latency budgets (list: 250ms, detail: 150ms, search: 250ms hard deadline) with SQLite progress handler interrupts and inline "results truncated" badges. This papers over slow queries with UX complexity rather than fixing the root cause. If a list query exceeds 250ms on a local SQLite database, the correct fix is adding an index or optimizing the query plan — not truncating results and showing a retry badge. The existing cancellation + stale-drop system already handles the interactive case (user navigates away before query completes). SQLite progress handlers are also tricky to implement correctly — they fire on every VM instruction, adding overhead to all queries, and the cancellation semantics interact poorly with SQLite's transaction semantics. The complexity-to-benefit ratio is wrong for a single-user local tool. If specific queries are slow, we fix them at the query/index level (Section 9.3.1 already documents required covering indexes).
+
+- **Adaptive render governor (runtime frame-time monitoring with automatic profile downgrading)** — rejected for the same reason as feedback-3's SLO telemetry and runtime monitoring proposals. The proposal adds a frame-time p95 sliding window, stream pressure detection, automatic profile switching (quality/balanced/speed), hysteresis for recovery, and a `--render-profile` CLI flag. This is appropriate for a multi-user rendering engine or game, not a single-user TUI. The capability detection in Section 3.4.1 already handles the static case (detect terminal capabilities, choose appropriate rendering). If the TUI is slow in tmux or over SSH, the user can pass `--ascii` or reduce their terminal size. Adding a runtime monitoring system with automatic visual degradation introduces a state machine, requires frame-time measurement infrastructure, needs hysteresis tuning to avoid flapping, and must be tested across all the profiles it can switch between. This is significant complexity for an edge case that affects one user once and is solved by a flag. The `--render-profile` flag itself is a reasonable addition as a static override — but the dynamic adaptation runtime is rejected.
