Query optimizer fixes for the `who` and `stats` commands based on
a systematic performance audit of the SQLite query plans.
who command (expert/reviews/detail modes):
- Add INDEXED BY idx_notes_diffnote_path_created hints to all DiffNote
queries. SQLite's planner was selecting idx_notes_system (38% of rows)
over the far more selective partial index (9.3% of rows). Measured
50-133x speedup on expert queries, 26x on reviews queries.
- Reorder JOIN clauses in detail mode's MR-author sub-select to match
the index scan direction (notes -> discussions -> merge_requests).
stats command:
- Replace 12+ sequential COUNT(*) queries with conditional aggregates
(COALESCE + SUM + CASE). Documents, dirty_sources, pending_discussion_
fetches, and pending_dependent_fetches tables each scanned once instead
of 2-3 times. Measured 1.7x speedup (109ms -> 65ms warm cache).
- Switch FTS document count from COUNT(*) on the virtual table to
COUNT(*) on documents_fts_docsize shadow table (B-tree scan vs FTS5
virtual table overhead). Measured 19x speedup for that single query.
Database: 61652 docs, 282K notes, 211K discussions, 1.5GB.
Robot mode consistency improvements across all command output:
Timing:
- Every robot JSON response now includes meta.elapsed_ms measuring
wall-clock time from command start to serialization. Agents can use
this to detect slow queries and tune --limit or --project filters.
Field selection (--fields):
- print_list_issues_json and print_list_mrs_json accept an optional
fields slice that prunes each item in the response array to only
the requested keys. A "minimal" preset expands to
[iid, title, state, updated_at_iso] for token-efficient agent scans.
- filter_fields and expand_fields_preset live in the new
src/cli/robot.rs module alongside RobotMeta.
Actionable error recovery:
- LoreError gains an actions() method returning concrete shell commands
an agent can execute to recover (e.g. "ollama serve" for
OllamaUnavailable, "lore init" for ConfigNotFound).
- RobotError now serializes an "actions" array (empty array omitted)
so agents can parse and offer one-click fixes.
Envelope consistency:
- show issue/MR JSON responses now use the standard
{"ok":true,"data":...,"meta":...} envelope instead of bare data,
matching all other commands.

Enables preview of operations without making changes, useful for
understanding what would happen before committing to a full sync.
Ingest dry-run (--dry-run flag):
- Shows resource type, sync mode (full vs incremental), project list
- Per-project info: existing count, has_cursor, last_synced timestamp
- No GitLab API calls, no database writes
Sync dry-run (--dry-run flag):
- Preview all four stages: issues ingest, MRs ingest, docs, embed
- Shows which stages would run vs be skipped (--no-docs, --no-embed)
- Per-project breakdown for both entity types
Stats repair dry-run (--dry-run flag):
- Shows what would be repaired without executing repairs
- "would fix" vs "fixed" indicator in terminal output
- dry_run: true field in JSON response
Implementation details:
- DryRunPreview struct captures project-level sync state
- SyncDryRunResult aggregates previews for all sync stages
- Terminal output uses yellow styling for "would" actions
- JSON output includes dry_run: true at top level
Flag handling:
- --dry-run and --no-dry-run pair for explicit control
- Defaults to false (normal operation)

Removes module-level doc comments (//! lines) and excessive inline doc
comments that were duplicating information already evident from:
- Function/struct names (self-documenting code)
- Type signatures (the what is clear from types)
- Implementation context (the how is clear from code)
Affected modules:
- cli/* - Removed command descriptions duplicating clap help text
- core/* - Removed module headers and obvious function docs
- documents/* - Removed extractor/regenerator/truncation docs
- embedding/* - Removed pipeline and chunking docs
- gitlab/* - Removed client and transformer docs (kept type definitions)
- ingestion/* - Removed orchestrator and ingestion docs
- search/* - Removed FTS and vector search docs
Philosophy: Code should be self-documenting. Comments should explain
"why" (business decisions, non-obvious constraints) not "what" (which
the code itself shows). This change reduces noise and maintenance burden
while keeping the codebase just as understandable.
Retains comments for:
- Non-obvious business logic
- Important safety invariants
- Complex algorithm explanations
- Public API boundaries where generated docs matter

Automated formatting and lint corrections from parallel agent work:
- cargo fmt: import reordering (alphabetical), line wrapping to respect
max width, trailing comma normalization, destructuring alignment,
function signature reformatting, match arm formatting
- clippy (pedantic): Range::contains() instead of manual comparisons,
i64::from() instead of `as i64` casts, .clamp() instead of
.max().min() chains, let-chain refactors (if-let with &&),
#[allow(clippy::too_many_arguments)] and
#[allow(clippy::field_reassign_with_default)] where warranted
- Removed trailing blank lines and extra whitespace
No behavioral changes. All existing tests pass unmodified.

Adds two new categories of integrity checks to 'lore stats --check':
Event FK integrity (3 queries):
- Detects orphaned resource_state_events where issue_id or
merge_request_id points to a non-existent parent entity
- Same check for resource_label_events and resource_milestone_events
- Under normal CASCADE operation these should always be zero; non-zero
indicates manual DB edits, bugs, or partial migration state
Queue health diagnostics:
- pending_dependent_fetches counts: pending, failed, and stuck (locked)
- queue_stuck_locks: Jobs with locked_at set (potential worker crashes)
- queue_max_attempts: Highest retry count across all jobs (signals
permanently failing jobs when > 3)
New IntegrityResult fields: orphan_state_events, orphan_label_events,
orphan_milestone_events, queue_stuck_locks, queue_max_attempts.
New QueueStats fields: pending_dependent_fetches,
pending_dependent_fetches_failed, pending_dependent_fetches_stuck.
Human output shows colored PASS/WARN/FAIL indicators:
- Red "!" for orphaned events (integrity failure)
- Yellow "!" for stuck locks and high retry counts (warnings)
- Dependent fetch queue line only shown when non-zero
All new queries are guarded by table_exists() checks for graceful
degradation on databases without migration 011 applied.

Extends the CLI with six new commands that complete the search pipeline:
- lore search <QUERY>: Hybrid search with mode selection (lexical,
hybrid, semantic), rich filtering (--type, --author, --project,
--label, --path, --after, --updated-after), result limits, and
optional explain mode showing RRF score breakdowns. Safe FTS mode
sanitizes user input; raw mode passes through for power users.
- lore stats: Document and index statistics with optional --check
for integrity verification and --repair to fix inconsistencies
(orphaned documents, missing FTS entries, stale dirty queue items).
- lore embed: Generate vector embeddings via Ollama. Supports
--retry-failed to re-attempt previously failed embeddings.
- lore generate-docs: Drain the dirty queue to regenerate documents.
--full seeds all entities for complete rebuild. --project scopes
to a single project.
- lore sync: Full pipeline orchestration (ingest issues + MRs,
generate-docs, embed) with --no-embed and --no-docs flags for
partial runs. Reports per-stage results and total elapsed time.
- lore health: Quick pre-flight check (config exists, DB exists,
schema current). Returns exit code 1 if unhealthy. Designed for
agent pre-flight scripts.
- lore robot-docs: Machine-readable command manifest for agent
self-discovery. Returns all commands, flags, examples, exit codes,
and recommended workflows as structured JSON.
Also enhances lore init with --gitlab-url, --token-env-var, and
--projects flags for fully non-interactive robot-mode initialization.
Fixes init's force/non-interactive precedence logic and adds JSON
output for robot mode.
Updates all command files for the GiError -> LoreError rename.
