who.rs: Add INDEXED BY idx_notes_diffnote_path_created to all DiffNote
query paths (expert, expert_details, reviews, path probes, suffix_probe).
SQLite planner was choosing idx_notes_system (106K rows, 38%) over the
partial index (26K rows, 9.3%) when LIKE predicates are present.
Measured: expert 1561ms->59ms (26x), reviews ~1200ms->16ms (75x).
stats.rs: Replace 12+ sequential COUNT(*) queries with conditional
aggregates (SUM(CASE WHEN...)) and use FTS5 shadow table
(documents_fts_docsize) instead of virtual table for counting.
Measured: warm 109ms->65ms (1.68x).
Comprehensive product requirements document for the gitlore TUI built on
FrankenTUI's Elm architecture (Msg -> update -> view). The PRD (7800+
lines) covers:
Architecture: Separate binary crate (lore-tui) with runtime delegation,
Elm-style Model/Cmd/Msg, DbManager with closure-based read pool + WAL,
TaskSupervisor for dedup/cancellation, EntityKey system for type-safe
entity references, CommandRegistry as single source of truth for
keybindings/palette/help.
Screens: Dashboard, IssueList, IssueDetail, MrList, MrDetail, Search
(lexical/hybrid/semantic with facets), Timeline (5-stage pipeline),
Who (expert/workload/reviews/active/overlap), Sync (live progress),
CommandPalette, Help overlay.
Infrastructure: InputMode state machine, Clock trait for deterministic
rendering, crash_context ring buffer with redaction, instance lock,
progressive hydration, session restore, grapheme-safe text truncation
(unicode-width + unicode-segmentation), terminal sanitization (ANSI/bidi/
C1 controls), entity LRU cache.
Testing: Snapshot tests via insta, event-fuzz, CLI/TUI parity, tiered
benchmark fixtures (S/M/L), query-plan CI enforcement, Phase 2.5
vertical slice gate.
9 plan-refine iterations (ChatGPT review -> Claude integration):
Iter 1-3: Connection pool, debounce, EntityKey, TaskSupervisor,
keyset pagination, capability-adaptive rendering
Iter 4-6: Separate binary crate, ANSI hardening, session restore,
read tx isolation, progressive hydration, unicode-width
Iter 7-9: Per-screen LoadState, CommandRegistry, InputMode, Clock,
log redaction, entity cache, search cancel SLO, crash diagnostics
Also includes the original tui-prd.md (ratatui-based, superseded by v2).
