+## 2026-03-18: Agent committed directly to master instead of worktree
+
+Commit `5f4591f` ("fix: update should_commit_stage test to match 5_done") was made directly on master by an agent (likely mergemaster). Agents should only commit to their feature branch or merge-queue branch, never to master directly. The commit content was correct but the target branch was wrong. Suspect the agent ran `git commit` in the project root instead of the merge worktree directory.

-## How Conflict Resolution Works
-The merge pipeline uses a temporary merge-queue branch and worktree to isolate merges from master. Simple additive conflicts (both branches adding code at the same location) are resolved automatically by keeping both additions. Complex conflicts (modifying the same lines differently) are reported without touching master.
+## Resolving Complex Conflicts Yourself
 
-## Fixing Minor Gate Failures
-If quality gates fail (cargo clippy, cargo test, npm run build, npm test), attempt to fix minor issues yourself before reporting to the human.
+When the auto-resolver fails, you have access to the merge worktree at `.story_kit/merge_workspace/`. Go in there and resolve the conflicts manually:
 
-**Fix yourself (up to 2 attempts total):**
+1. Run `git diff --name-only --diff-filter=U` in the merge worktree to list conflicted files
+2. **Build context before touching code.** Run `git log --oneline master...HEAD` on the feature branch to see its commits. Then run `git log --oneline --since="$(git log -1 --format=%ci <feature-branch-base-commit>)" master` to see what landed on master since the branch was created. Read the story files in `.story_kit/work/` for any recently merged stories that touch the same files — this tells you WHY master changed and what must be preserved.
+3. Read each conflicted file and understand both sides of the conflict
+4. **Understand intent, not just syntax.** The feature branch may be behind master — master's version of shared infrastructure is almost always correct. The feature branch's contribution is the NEW functionality it adds. Your job is to integrate the new into master's structure, not pick one side.
+5. Resolve by integrating the feature's new functionality into master's code structure
+5. Stage resolved files with `git add`
+6. Run `cargo check` (and `npm run build` if frontend changed) to verify compilation
+7. If it compiles, commit and re-trigger merge_agent_work
+
+### Common conflict patterns in this project:
+
+**Story file rename/rename conflicts:** Both branches moved the story .md file to different pipeline directories. Resolution: `git rm` both sides — story files in `work/2_current/`, `work/3_qa/`, `work/4_merge/` are gitignored and don't need to be committed.
+
+**bot.rs tokio::select! conflicts:** Master has a `tokio::select!` loop in `handle_message()` that handles permission forwarding (story 275). Feature branches created before story 275 have a simpler direct `provider.chat_stream().await` call. Resolution: KEEP master's tokio::select! loop. Integrate only the feature's new logic (e.g. typing indicators, new callbacks) into the existing loop structure. Do NOT replace the loop with the old direct call.
+
+**Duplicate functions/imports:** The auto-resolver keeps both sides, producing duplicates. Resolution: keep one copy (prefer master's version), delete the duplicate.
+
+**Formatting-only conflicts:** Both sides reformatted the same code differently. Resolution: pick either side (prefer master).

+# Refactor 260: Upgrade libsqlite3-sys
+
+## Description
+
+Upgrade the `libsqlite3-sys` dependency from `0.35.0` to `0.37.0`. The crate is used with `features = ["bundled"]` for static builds.
+
+## Version Notes
+
+- Current: `libsqlite3-sys 0.35.0` (pinned transitively by `matrix-sdk 0.16.0` → `matrix-sdk-sqlite` → `rusqlite 0.37.x`)
+- Target: `libsqlite3-sys 0.37.0`
+- Latest upstream rusqlite: `0.39.0`
+- **Blocker**: `matrix-sdk 0.16.0` pins `rusqlite 0.37.x` which pins `libsqlite3-sys 0.35.0`. A clean upgrade requires either waiting for matrix-sdk to bump their rusqlite dep, or upgrading matrix-sdk itself.
+- **Reverted 2026-03-17**: A previous coder vendored the entire rusqlite crate with a fake `0.37.99` version and patched its libsqlite3-sys dep. This was too hacky — reverted to clean `0.35.0`.
+
+## Acceptance Criteria
+
+- [ ] `libsqlite3-sys` is upgraded to `0.37.0` via a clean dependency path (no vendored forks)
+- [ ] `cargo build` succeeds
+- [ ] All tests pass
+- [ ] No `[patch.crates-io]` hacks or vendored crates

+# Story 280: Long-running supervisor agent with periodic pipeline polling
+
+## User Story
+
+As a project owner, I want a long-running supervisor agent (opus) that automatically monitors the pipeline, assigns agents, resolves stuck items, and handles routine operational tasks, so that I don't have to manually check status, kick agents, or babysit the pipeline in every conversation.
+
+## Acceptance Criteria
+
+- [ ] Server can start a persistent supervisor agent that stays alive across the session (not per-story)
+- [ ] Server prods the supervisor periodically (default 30s, configurable in project.toml) with a pipeline status update
+- [ ] Supervisor auto-assigns agents to unassigned items in current/qa/merge stages
+- [ ] Supervisor detects stuck agents (no progress for configurable timeout) and restarts them
+- [ ] Supervisor detects merge failures and sends stories back to current for rebase when appropriate
+- [ ] Supervisor can be chatted with via Matrix (timmy relays to supervisor) or via the web UI
+- [ ] Supervisor logs its decisions so the human can review what it did and why
+- [ ] Polling interval is configurable in project.toml (e.g. supervisor_poll_interval_secs = 30)
+- [ ] Supervisor logs persistent/recurring problems to `.story_kit/problems.md` with timestamp, description, and frequency — humans review this file periodically to create stories for systemic issues

+- Supervisor accepting or merging stories to master (human job)

-# Spike 92: Stop auto-committing intermediate pipeline moves
-
-## Goal
-
-Determine how to stop the filesystem watcher from auto-committing every pipeline stage move (upcoming -> current -> qa -> merge -> done -> archive) while still committing at terminal states (creation in upcoming, acceptance in done and archived). This keeps git history clean while preserving cross-machine portability for completed work.
-
-## Context
-
-The watcher in `server/src/io/watcher.rs` currently auto-commits every file change in `.story_kit/work/`. A single story run generates 5+ commits just from pipeline moves:
-- `story-kit: create 42_story_foo`
-- `story-kit: start 42_story_foo`
-- `story-kit: queue 42_story_foo for QA`
-- `story-kit: queue 42_story_foo for merge`
-- `story-kit: accept 42_story_foo`
-
-Since story runs complete relatively quickly, the intermediate state (current/qa/merge) is transient and doesn't need to be committed. Only creation and archival are meaningful checkpoints.
-
-## Questions to Answer
-
-1. Can we filter `stage_metadata()` to only commit for `1_upcoming` and `5_archived` stages while still broadcasting `WatcherEvent`s for all stages (so the frontend stays in sync)?
-2. Should we keep `git add -A .story_kit/work/` for the committed stages, or narrow it to only the specific file?
-3. What happens if the server crashes mid-pipeline? Uncommitted moves are lost — is this acceptable given the story can just be re-run?
-4. Should intermediate moves be `.gitignore`d at the directory level, or is filtering in the watcher sufficient?
-5. Do any other parts of the system (agent worktree setup, merge_agent_work, sparse checkout) depend on intermediate pipeline files being committed to master?
-
-## Approach to Investigate
-
-### Option A: Filter in `flush_pending()`
-- In `flush_pending()`, still broadcast the `WatcherEvent` for all stages
-- Only call `git_add_work_and_commit()` for stages `1_upcoming` and `5_archived`
-- Simplest change — ~5 lines modified in `watcher.rs`
-
-### Option B: Two-tier watcher
-- Split into "commit-worthy" events (create, archive) and "notify-only" events (start, qa, merge)
-- Commit-worthy events go through git
-- Notify-only events just broadcast to WebSocket clients
-- More explicit but same end result as Option A
-
-### Option C: .gitignore intermediate directories
-- Add `2_current/`, `3_qa/`, `4_merge/` to `.gitignore`
-- Watcher still sees events (gitignore doesn't affect filesystem watching)
-- Git naturally ignores them
-- Risk: harder to debug, `git status` won't show pipeline state
-
-## Acceptance Criteria
-
-- [ ] Spike document updated with findings and recommendation
-- [ ] If Option A is viable: prototype the change and verify git log is clean during a full story run
-- [ ] Confirm frontend still receives real-time pipeline updates for all stages
-- [ ] Confirm no other system depends on intermediate pipeline commits being on master
-- [ ] Identify any edge cases (server crash, manual git operations, multi-machine sync)

+
+## Investigation Notes (2026-03-18)
+
+The current implementation attempts session resumption via `--resume <session_id>` but it's not working:
+
+### Code path: how session resumption is supposed to work
+
+1. `server/src/matrix/bot.rs:671-676` — `handle_message()` reads `conv.session_id` from the per-room `RoomConversation` to get the resume ID.
+2. `server/src/matrix/bot.rs:717` — passes `resume_session_id` to `provider.chat_stream()`.
+3. `server/src/llm/providers/claude_code.rs:57` — `chat_stream()` stores it as `resume_id`.
+4. `server/src/llm/providers/claude_code.rs:170-173` — if `resume_session_id` is `Some`, appends `--resume <id>` to the `claude -p` command.
+5. `server/src/llm/providers/claude_code.rs:348` — `process_json_event()` looks for `json["session_id"]` in each streamed NDJSON event and sends it via a oneshot channel (`sid_tx`).
+6. `server/src/llm/providers/claude_code.rs:122` — after the PTY exits, `sid_rx.await.ok()` captures the session ID (or `None` if never sent).
+7. `server/src/matrix/bot.rs:785-787` — stores `new_session_id` back into `conv.session_id` and persists via `save_history()`.
+
+### What's broken
+
+- **No session_id captured:** `.story_kit/matrix_history.json` contains conversation entries but no `session_id`. `RoomConversation.session_id` is always `None`.
+- **Root cause:** `claude -p --output-format stream-json` may not emit a `session_id` in its NDJSON events, or the parser at step 5 isn't matching the actual event shape. The oneshot channel never fires.
+- **Effect:** Every message spawns a fresh Claude Code process with no `--resume` flag. Each turn is a blank slate.
+- **History persistence works fine** — serialization round-trips correctly (test at `bot.rs:1335-1339`). The problem is purely that `--resume` is never invoked.
+
+### Debugging steps
+
+1. Run `claude -p "hello" --output-format stream-json --verbose 2>/dev/null` manually and inspect the NDJSON for a `session_id` field. Check what event type carries it and whether the key name matches what `process_json_event()` expects.
+2. If `session_id` is present but nested differently (e.g. inside an `event` wrapper), fix the JSON path at `claude_code.rs:348`.
+3. If `-p` mode doesn't emit `session_id` at all, consider an alternative: pass conversation history as a structured prompt prefix, or switch to the Claude API directly.
+
+### Previous attempt failed (2026-03-18)
+
+A sonnet coder attempted this story but did NOT fix the root cause. It rewrote the `chat_stream()` call in `bot.rs` to look identical to what was already there — it never investigated why `session_id` isn't being captured. The merge auto-resolver then jammed the duplicate call inside the `tokio::select!` permission loop, producing mismatched braces. The broken merge was reverted.
+
+**What the coder must actually do:**
+
+1. **Do NOT rewrite the `chat_stream()` call or the `tokio::select!` loop in `bot.rs`.** That code is correct and handles permission forwarding (story 275). Do not touch it.
+2. **The bug is in `claude_code.rs`, not `bot.rs`.** The `process_json_event()` function at line ~348 looks for `json["session_id"]` but it's likely never finding it. Start by running step 1 above to see what the actual NDJSON output looks like.
+3. **If `claude -p` doesn't emit `session_id` at all**, the `--resume` approach won't work. In that case, the fix is to pass conversation history as a prompt prefix (prepend prior turns to the user message) or use `--continue` instead of `--resume`, or call the Claude API directly instead of shelling out to the CLI.
+4. **Rebase onto current master before starting.** Master has changed significantly (spike 92, story 275 permission handling, gitignore changes).

+Determine how to stop the filesystem watcher from auto-committing every pipeline stage move (upcoming -> current -> qa -> merge -> done -> archive) while still committing at terminal states (creation in upcoming, acceptance in done and archived). This keeps git history clean while preserving cross-machine portability for completed work.
+
+## Context
+
+The watcher in `server/src/io/watcher.rs` currently auto-commits every file change in `.story_kit/work/`. A single story run generates 5+ commits just from pipeline moves:
+- `story-kit: create 42_story_foo`
+- `story-kit: start 42_story_foo`
+- `story-kit: queue 42_story_foo for QA`
+- `story-kit: queue 42_story_foo for merge`
+- `story-kit: accept 42_story_foo`
+
+Since story runs complete relatively quickly, the intermediate state (current/qa/merge) is transient and doesn't need to be committed. Only creation and archival are meaningful checkpoints.
+
+## Questions to Answer
+
+1. Can we filter `stage_metadata()` to only commit for `1_upcoming` and `6_archived` stages while still broadcasting `WatcherEvent`s for all stages (so the frontend stays in sync)?
+2. Should we keep `git add -A .story_kit/work/` for the committed stages, or narrow it to only the specific file?
+3. What happens if the server crashes mid-pipeline? Uncommitted moves are lost — is this acceptable given the story can just be re-run?
+4. Should intermediate moves be `.gitignore`d at the directory level, or is filtering in the watcher sufficient?
+5. Do any other parts of the system (agent worktree setup, merge_agent_work, sparse checkout) depend on intermediate pipeline files being committed to master?
+
+## Findings
+
+### Q1: Can we filter to only commit terminal stages?
+
+**Yes.** The fix is in `flush_pending()`, not `stage_metadata()`. We add a `should_commit_stage()` predicate that returns `true` only for `1_upcoming` and `6_archived`. The event broadcast path is decoupled from the commit path — `flush_pending()` always broadcasts a `WatcherEvent` regardless of whether it commits.
+
+Prototype implemented: added `COMMIT_WORTHY_STAGES` constant and `should_commit_stage()` function. The change is ~15 lines including the constant, predicate, and conditional in `flush_pending()`.
+
+### Q2: Keep `git add -A .story_kit/work/` or narrow to specific file?
+
+**Keep `git add -A .story_kit/work/`.** When committing a terminal stage (e.g. `6_archived`), the file has been moved from a previous stage (e.g. `5_done`). Using `-A` on the whole work directory captures both the addition in the new stage and the deletion from the old stage in a single commit. Narrowing to the specific file would miss the deletion side of the move.
+
+### Q3: Server crash mid-pipeline — acceptable?
+
+**Yes.** If the server crashes while a story is in `2_current`, `3_qa`, or `4_merge`, the file is lost from git but:
+- The story file still exists on the filesystem (it's just not committed)
+- The agent's work is in its own feature branch/worktree (independent of pipeline file state)
+- The story can be re-queued from `1_upcoming` which IS committed
+- Pipeline state is transient by nature — it reflects "what's happening right now", not permanent record
+
+### Q4: `.gitignore` vs watcher filtering?
+
+**Watcher filtering is sufficient.** `.gitignore` approach (Option C) has downsides:
+- `git status` won't show pipeline state, making debugging harder
+- If you ever need to commit an intermediate state (e.g. for a new feature), you'd have to fight `.gitignore`
+- Watcher filtering is explicit and easy to understand — a constant lists the commit-worthy stages
+- No risk of accidentally ignoring files that should be tracked
+
+### Q5: Dependencies on intermediate pipeline commits?
+
+**None found.** Thorough investigation confirmed:
+
+1. **`merge_agent_work`** (`agents/merge.rs`): Creates a temporary `merge-queue/` branch and worktree. Reads the feature branch, not pipeline files. After merge, calls `move_story_to_archived()` which is a filesystem operation.
+
+2. **Agent worktree setup** (`worktree.rs`): Creates worktrees from feature branches. Sparse checkout is a no-op (disabled). Does not read pipeline file state from git.
+
+3. **MCP tool handlers** (`agents/lifecycle.rs`): `move_story_to_current()`, `move_story_to_merge()`, `move_story_to_qa()`, `move_story_to_archived()` — all pure filesystem `fs::rename()` operations. None perform git commits.
+
+4. **Frontend** (`http/workflow.rs`): `load_pipeline_state()` reads directories from the filesystem directly via `fs::read_dir()`. Never calls git. WebSocket events keep the frontend in sync.
+
+5. **No git inspection commands** reference pipeline stage directories anywhere in the codebase.
+
+### Edge Cases
+
+- **Multi-machine sync:** Only `1_upcoming` and `6_archived` are committed. If you push/pull, you'll see story creation and archival but not intermediate pipeline state. This is correct — intermediate state is machine-local runtime state.
+- **Manual git operations:** `git status` will show uncommitted files in intermediate stages. This is actually helpful for debugging — you can see what's in the pipeline without grepping git log.
+- **Sweep (5_done → 6_archived):** The sweep moves files to `6_archived`, which triggers a watcher event that WILL commit (since `6_archived` is a terminal stage). This naturally captures the final state.
+
+## Approach to Investigate
+
+### Option A: Filter in `flush_pending()` ← **RECOMMENDED**
+- In `flush_pending()`, still broadcast the `WatcherEvent` for all stages
+- Only call `git_add_work_and_commit()` for stages `1_upcoming` and `6_archived`
+- Simplest change — ~15 lines modified in `watcher.rs`
+
+### Option B: Two-tier watcher
+- Split into "commit-worthy" events (create, archive) and "notify-only" events (start, qa, merge)
+- Commit-worthy events go through git
+- Notify-only events just broadcast to WebSocket clients
+- More explicit but same end result as Option A
+
+### Option C: .gitignore intermediate directories
+- Add `2_current/`, `3_qa/`, `4_merge/` to `.gitignore`
+- Watcher still sees events (gitignore doesn't affect filesystem watching)
+- Git naturally ignores them
+- Risk: harder to debug, `git status` won't show pipeline state
+
+## Recommendation
+
+**Option A is viable and implemented.** The prototype is in `server/src/io/watcher.rs`:
+- Added `COMMIT_WORTHY_STAGES` constant: `["1_upcoming", "6_archived"]`
+- Added `should_commit_stage()` predicate
+- Modified `flush_pending()` to conditionally commit based on stage, while always broadcasting events
+- All 872 tests pass, clippy clean
+
+A full story run will now produce only 2 pipeline commits instead of 5+:
+- `story-kit: create 42_story_foo` (creation in `1_upcoming`)
+- `story-kit: accept 42_story_foo` (archival in `6_archived`)
+
+The intermediate moves (`start`, `queue for QA`, `queue for merge`, `done`) are still broadcast to WebSocket clients for real-time frontend updates, but no longer clutter git history.
+
+## Acceptance Criteria
+
+- [x] Spike document updated with findings and recommendation
+- [x] If Option A is viable: prototype the change and verify git log is clean during a full story run
+- [x] Confirm frontend still receives real-time pipeline updates for all stages
+- [x] Confirm no other system depends on intermediate pipeline commits being on master
+- [x] Identify any edge cases (server crash, manual git operations, multi-machine sync)

+# Bug 264: Claude Code session ID not persisted across browser refresh
+
+## Description
+
+The Claude Code provider uses a session_id to resume conversations via `--resume <id>`. This session_id is stored in React state (`claudeSessionId`) but is NOT persisted to localStorage. After a browser refresh, the session_id is lost (`null`), so Claude Code cannot resume the prior session.
+
+A fallback exists (`build_claude_code_context_prompt` in `server/src/llm/chat.rs:188`) that injects prior messages as flattened text inside a `<conversation_history>` block, but this loses structure (tool calls, tool results, reasoning) and Claude Code treats it as informational text rather than actual conversation turns. In practice, the LLM does not retain meaningful context after refresh.
+
+This is the root cause behind bug 245 (chat history persistence regression). The localStorage message persistence from story 145 works correctly for the UI, but the LLM context is not properly restored because the session cannot be resumed.
+
+Key files:
+- `frontend/src/components/Chat.tsx:174` — `claudeSessionId` is ephemeral React state
+- `frontend/src/components/Chat.tsx:553` — session_id only sent when non-null
+- `server/src/llm/chat.rs:278` — backend branches on session_id presence
+- `server/src/llm/providers/claude_code.rs:44` — `--resume` flag passed to Claude CLI
+
+## How to Reproduce
+
+1. Open the Story Kit web UI and select claude-code-pty as the model
+2. Have a multi-turn conversation with the agent
+3. Refresh the browser (F5 or Cmd+R)
+4. Send a new message referencing the prior conversation
+5. The LLM has no knowledge of the prior conversation
+
+## Actual Result
+
+After refresh, claudeSessionId is null. Claude Code spawns a fresh session without --resume. The fallback text injection is too lossy to provide meaningful context. The LLM behaves as if the conversation never happened.
+
+## Expected Result
+
+After refresh, the Claude Code session is resumed via --resume, giving the LLM full context of the prior conversation including tool calls, reasoning, and all turns.
+
+## Acceptance Criteria
+
+- [ ] claudeSessionId is persisted to localStorage (scoped by project path) and restored on component mount
+- [ ] After browser refresh, the next chat message includes session_id in the ProviderConfig
+- [ ] Claude Code receives --resume with the persisted session_id after refresh
+- [ ] Clearing the session (clear button) also clears the persisted session_id
+- [ ] After server restart with session files intact on disk, conversation resumes correctly

+# Story 265: Spikes skip merge and stop for human review
+
+## User Story
+
+As a user, I want spike work items to stop after QA instead of auto-advancing to the merge stage, so that I can review the spike's findings and prototype code in the worktree before deciding what to do with them.
+
+## Context
+
+Spikes are investigative — their value is the findings and any prototype code, not a merge to master. The user needs to:
+- Read the spike document with findings
+- Review prototype code in the worktree
+- Optionally build and run the prototype to validate the approach
+- Then manually decide: archive the spike and create follow-up stories, or reject and re-investigate
+
+Currently all work items follow the same pipeline: coder → QA → merge → done. Spikes should diverge after QA and wait for human review instead of auto-advancing to merge.
+
+## Acceptance Criteria
+
+- [ ] Items with `_spike_` in the filename skip the merge stage after QA passes
+- [ ] After QA, spike items remain accessible for human review (worktree preserved, not cleaned up)
+- [ ] Spikes do not auto-advance to `4_merge/` — they stay in `3_qa/` or move to a review-hold state
+- [ ] The human can manually archive the spike when done reviewing
+- [ ] Non-spike items (stories, bugs, refactors) continue through the full pipeline as before
+
+## Out of Scope
+
+- New UI for spike review (manual file inspection is fine)
+- Changes to the spike creation flow

+# Bug 270: QA test server overwrites root .mcp.json with wrong port
+
+## Description
+
+When the QA agent starts a test server in a worktree (e.g. on port 3012), that server auto-detects the shared project root and calls open_project, which writes .mcp.json with the test server's port. This clobbers the root .mcp.json that should always point to the main server (port 3001).
+
+Root cause: open_project in server/src/io/fs.rs:527 unconditionally calls write_mcp_json(&p, port) with its own port. Because worktrees share .story_kit/ with the real project, the test server resolves to the real project root and overwrites the root .mcp.json instead of writing to its own worktree directory.
+
+Fix: Remove the write_mcp_json call from open_project entirely. Worktree .mcp.json files are already written correctly during worktree creation (worktree.rs:81,97), and the root .mcp.json is committed in git. open_project should not touch it.
+
+## How to Reproduce
+
+1. QA agent starts on a story\n2. QA agent starts a test server in the worktree on a non-default port (e.g. 3012)\n3. Test server auto-opens the project root\n4. Root .mcp.json is overwritten with test port
+
+## Actual Result
+
+Root .mcp.json contains the QA test server's port (e.g. 3012) instead of the main server's port (3001). Interactive Claude sessions lose MCP connectivity.
+
+## Expected Result
+
+Root .mcp.json always points to the primary server's port. Test servers started by QA agents should not overwrite it.
+
+## Acceptance Criteria
+
+- [ ] QA test servers do not overwrite root .mcp.json
+- [ ] Root .mcp.json always reflects the primary server's port
+- [ ] Worktree .mcp.json files are only written during worktree creation

-Rusqlite is an ergonomic wrapper for using SQLite from Rust.
-
-Historically, the API was based on the one from [`rust-postgres`](https://github.com/sfackler/rust-postgres). However, the two have diverged in many ways, and no compatibility between the two is intended.
-
-## Usage
-
-In your Cargo.toml:
-
-```toml
-[dependencies]
-# `bundled` causes us to automatically compile and link in an up to date
-# version of SQLite for you. This avoids many common build issues, and
-# avoids depending on the version of SQLite on the users system (or your
-# system), which may be old or missing. It's the right choice for most
-# programs that control their own SQLite databases.
-#
-# That said, it's not ideal for all scenarios and in particular, generic
-# libraries built around `rusqlite` should probably not enable it, which
-# is why it is not a default feature -- it could become hard to disable.
-rusqlite = { version = "0.39.0", features = ["bundled"] }
-```
-
-Simple example usage:
-
-```rust
-use rusqlite::{Connection, Result};
-
-#[derive(Debug)]
-struct Person {
-    id: i32,
-    name: String,
-    data: Option<Vec<u8>>,
-}
-
-fn main() -> Result<()> {
-    let conn = Connection::open_in_memory()?;
-
-    conn.execute(
-        "CREATE TABLE person (
-            id    INTEGER PRIMARY KEY,
-            name  TEXT NOT NULL,
-            data  BLOB
-        )",
-        (), // empty list of parameters.
-    )?;
-    let me = Person {
-        id: 0,
-        name: "Steven".to_string(),
-        data: None,
-    };
-    conn.execute(
-        "INSERT INTO person (name, data) VALUES (?1, ?2)",
-        (&me.name, &me.data),
-    )?;
-
-    let mut stmt = conn.prepare("SELECT id, name, data FROM person")?;
-    let person_iter = stmt.query_map([], |row| {
-        Ok(Person {
-            id: row.get(0)?,
-            name: row.get(1)?,
-            data: row.get(2)?,
-        })
-    })?;
-
-    for person in person_iter {
-        println!("Found person {:?}", person.unwrap());
-    }
-    Ok(())
-}
-```

-### Supported SQLite Versions
-
-The base `rusqlite` package supports SQLite version 3.34.1 or newer. If you need
-support for older versions, please file an issue. Some cargo features require a
-newer SQLite version; see details below.
-
-### Optional Features
-
-Rusqlite provides several features that are behind [Cargo
-features](https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section). They are:
-
-* [`load_extension`](https://docs.rs/rusqlite/~0/rusqlite/struct.LoadExtensionGuard.html)
-  allows loading dynamic library-based SQLite extensions.
-* `loadable_extension` to program [loadable extension](https://sqlite.org/loadext.html) in Rust.
-* [`backup`](https://docs.rs/rusqlite/~0/rusqlite/backup/index.html)
-  allows use of SQLite's online backup API.
-* [`functions`](https://docs.rs/rusqlite/~0/rusqlite/functions/index.html)
-  allows you to load Rust closures into SQLite connections for use in queries.
-* `window` for [window function](https://www.sqlite.org/windowfunctions.html) support (`fun(...) OVER ...`). (Implies `functions`.)
-* [`trace`](https://docs.rs/rusqlite/~0/rusqlite/trace/index.html)
-  allows hooks into SQLite's tracing and profiling APIs.
-* [`blob`](https://docs.rs/rusqlite/~0/rusqlite/blob/index.html)
-  gives `std::io::{Read, Write, Seek}` access to SQL BLOBs.
-* [`limits`](https://docs.rs/rusqlite/~0/rusqlite/struct.Connection.html#method.limit)
-  allows you to set and retrieve SQLite's per connection limits.
-* `serde_json` implements [`FromSql`](https://docs.rs/rusqlite/~0/rusqlite/types/trait.FromSql.html)
-  and [`ToSql`](https://docs.rs/rusqlite/~0/rusqlite/types/trait.ToSql.html) for the
-  `Value` type from the [`serde_json` crate](https://crates.io/crates/serde_json).
-* `chrono` implements [`FromSql`](https://docs.rs/rusqlite/~0/rusqlite/types/trait.FromSql.html)
-  and [`ToSql`](https://docs.rs/rusqlite/~0/rusqlite/types/trait.ToSql.html) for various
-  types from the [`chrono` crate](https://crates.io/crates/chrono).
-* `time` implements [`FromSql`](https://docs.rs/rusqlite/~0/rusqlite/types/trait.FromSql.html)
-  and [`ToSql`](https://docs.rs/rusqlite/~0/rusqlite/types/trait.ToSql.html) for various
-  types from the [`time` crate](https://crates.io/crates/time).
-* `jiff` implements [`FromSql`](https://docs.rs/rusqlite/~0/rusqlite/types/trait.FromSql.html)
-  and [`ToSql`](https://docs.rs/rusqlite/~0/rusqlite/types/trait.ToSql.html) for the
-  `Value` type from the [`jiff` crate](https://crates.io/crates/jiff).
-* `url` implements [`FromSql`](https://docs.rs/rusqlite/~0/rusqlite/types/trait.FromSql.html)
-  and [`ToSql`](https://docs.rs/rusqlite/~0/rusqlite/types/trait.ToSql.html) for the
-  `Url` type from the [`url` crate](https://crates.io/crates/url).
-* `bundled` uses a bundled version of SQLite.  This is a good option for cases where linking to SQLite is complicated, such as Windows.
-* `sqlcipher` looks for the SQLCipher library to link against instead of SQLite. This feature overrides `bundled`.
-* `bundled-sqlcipher` uses a bundled version of SQLCipher. This searches for and links against a system-installed crypto library to provide the crypto implementation.
-* `bundled-sqlcipher-vendored-openssl` allows using bundled-sqlcipher with a vendored version of OpenSSL (via the `openssl-sys` crate) as the crypto provider.
-  - As the name implies this depends on the `bundled-sqlcipher` feature, and automatically turns it on.
-  - If turned on, this uses the [`openssl-sys`](https://crates.io/crates/openssl-sys) crate, with the `vendored` feature enabled in order to build and bundle the OpenSSL crypto library.
-* `hooks` for [Commit, Rollback](http://sqlite.org/c3ref/commit_hook.html) and [Data Change](http://sqlite.org/c3ref/update_hook.html) notification callbacks.
-* `preupdate_hook` for [preupdate](https://sqlite.org/c3ref/preupdate_count.html) notification callbacks. (Implies `hooks`.)
-* `unlock_notify` for [Unlock](https://sqlite.org/unlock_notify.html) notification.
-* `vtab` for [virtual table](https://sqlite.org/vtab.html) support (allows you to write virtual table implementations in Rust). Currently, only read-only virtual tables are supported.
-* `series` exposes [`generate_series(...)`](https://www.sqlite.org/series.html) Table-Valued Function. (Implies `vtab`.)
-* [`csvtab`](https://sqlite.org/csv.html), CSV virtual table written in Rust. (Implies `vtab`.)
-* [`array`](https://sqlite.org/carray.html), The `rarray()` Table-Valued Function. (Implies `vtab`.)
-* `fallible_uint` allows storing values of type `u64`, `usize`, `NonZeroU64`, `NonZeroUsize` but only if <= `i64::MAX`.
-* `i128_blob` allows storing values of type `i128` type in SQLite databases. Internally, the data is stored as a 16 byte big-endian blob, with the most significant bit flipped, which allows ordering and comparison between different blobs storing i128s to work as expected.
-* `uuid` allows storing and retrieving `Uuid` values from the [`uuid`](https://docs.rs/uuid/) crate using blobs.
-* [`session`](https://sqlite.org/sessionintro.html), Session module extension. Requires `buildtime_bindgen` feature. (Implies `hooks`.)
-* `extra_check` fails when a query passed to `execute` is readonly and has a column count > 0.
-* `column_decltype` provides `columns()` method for Statements and Rows; omit if linking to a version of SQLite/SQLCipher compiled with `-DSQLITE_OMIT_DECLTYPE`.
-* `collation` exposes [`sqlite3_create_collation_v2`](https://sqlite.org/c3ref/create_collation.html).
-* `serialize` exposes [`sqlite3_serialize`](http://sqlite.org/c3ref/serialize.html) (3.23.0).
-* `rusqlite-macros` enables the use of the [`prepare_and_bind`](https://docs.rs/rusqlite/~0/rusqlite/macro.prepare_and_bind.html)
-  and [`prepare_cached_and_bind`](https://docs.rs/rusqlite/~0/rusqlite/macro.prepare_cached_and_bind.html)
-  procedural macros, which allow capturing identifiers in SQL statements.

-## Notes on building rusqlite and libsqlite3-sys
-
-`libsqlite3-sys` is a separate crate from `rusqlite` that provides the Rust
-declarations for SQLite's C API. By default, `libsqlite3-sys` attempts to find a SQLite library that already exists on your system using pkg-config, or a
-[Vcpkg](https://github.com/Microsoft/vcpkg) installation for MSVC ABI builds.
-
-You can adjust this behavior in a number of ways:
-
-* If you use the `bundled`, `bundled-sqlcipher`, or `bundled-sqlcipher-vendored-openssl` features, `libsqlite3-sys` will use the
-  [cc](https://crates.io/crates/cc) crate to compile SQLite or SQLCipher from source and
-  link against that. This source is embedded in the `libsqlite3-sys` crate and
-  is currently SQLite 3.51.3 (as of `rusqlite` 0.39.0 / `libsqlite3-sys`
-  0.37.0).  This is probably the simplest solution to any build problems. You can enable this by adding the following in your `Cargo.toml` file:
-  ```toml
-  [dependencies.rusqlite]
-  version = "0.39.0"
-  features = ["bundled"]
-  ```
-* When using any of the `bundled` features, the build script will honor `SQLITE_MAX_VARIABLE_NUMBER` and `SQLITE_MAX_EXPR_DEPTH` variables. It will also honor a `LIBSQLITE3_FLAGS` variable, which can have a format like `"-USQLITE_ALPHA -DSQLITE_BETA SQLITE_GAMMA ..."`. That would disable the `SQLITE_ALPHA` flag, and set the `SQLITE_BETA` and `SQLITE_GAMMA` flags. (The initial `-D` can be omitted, as on the last one.)
-* When using `bundled-sqlcipher` (and not also using `bundled-sqlcipher-vendored-openssl`), `libsqlite3-sys` will need to
-  link against crypto libraries on the system. If the build script can find a `libcrypto` from OpenSSL or LibreSSL (it will consult `OPENSSL_LIB_DIR`/`OPENSSL_INCLUDE_DIR` and `OPENSSL_DIR` environment variables), it will use that. If building on and for Macs, and none of those variables are set, it will use the system's SecurityFramework instead.
-
-* When linking against a SQLite (or SQLCipher) library already on the system (so *not* using any of the `bundled` features), you can set the `SQLITE3_LIB_DIR` (or `SQLCIPHER_LIB_DIR`) environment variable to point to a directory containing the library. You can also set the `SQLITE3_INCLUDE_DIR` (or `SQLCIPHER_INCLUDE_DIR`) variable to point to the directory containing `sqlite3.h`.
-* Installing the sqlite3 development packages will usually be all that is required, but
-  the build helpers for [pkg-config](https://github.com/alexcrichton/pkg-config-rs)
-  and [vcpkg](https://github.com/mcgoo/vcpkg-rs) have some additional configuration
-  options. The default when using vcpkg is to dynamically link,
-  which must be enabled by setting `VCPKGRS_DYNAMIC=1` environment variable before build.
-  `vcpkg install sqlite3:x64-windows` will install the required library.
-* When linking against a SQLite (or SQLCipher) library already on the system, you can set the `SQLITE3_STATIC` (or `SQLCIPHER_STATIC`) environment variable to 1 to request that the library be statically instead of dynamically linked.
-
-
-### Binding generation
-
-We use [bindgen](https://crates.io/crates/bindgen) to generate the Rust
-declarations from SQLite's C header file. `bindgen`
-[recommends](https://github.com/servo/rust-bindgen#library-usage-with-buildrs)
-running this as part of the build process of libraries that used this. We tried
-this briefly (`rusqlite` 0.10.0, specifically), but it had some annoyances:
-
-* The build time for `libsqlite3-sys` (and therefore `rusqlite`) increased
-  dramatically.
-* Running `bindgen` requires a relatively-recent version of Clang, which many
-  systems do not have installed by default.
-* Running `bindgen` also requires the SQLite header file to be present.
-
-As of `rusqlite` 0.10.1, we avoid running `bindgen` at build-time by shipping
-pregenerated bindings for several versions of SQLite. When compiling
-`rusqlite`, we use your selected Cargo features to pick the bindings for the
-minimum SQLite version that supports your chosen features. If you are using
-`libsqlite3-sys` directly, you can use the same features to choose which
-pregenerated bindings are chosen:
-
-* `min_sqlite_version_3_34_1` - SQLite 3.34.1 bindings (this is the default)
-
-If you use any of the `bundled` features, you will get pregenerated bindings for the
-bundled version of SQLite/SQLCipher. If you need other specific pregenerated binding
-versions, please file an issue. If you want to run `bindgen` at buildtime to
-produce your own bindings, use the `buildtime_bindgen` Cargo feature.
-
-If you enable the `modern_sqlite` feature, we'll use the bindings we would have
-included with the bundled build. You generally should have `buildtime_bindgen`
-enabled if you turn this on, as otherwise you'll need to keep the version of
-SQLite you link with in sync with what rusqlite would have bundled, (usually the
-most recent release of SQLite). Failing to do this will cause a runtime error.
-
-## Contributing
-
-Rusqlite has many features, and many of them impact the build configuration in
-incompatible ways. This is unfortunate, and makes testing changes hard.
-
-To help here: you generally should ensure that you run tests/lint for
-`--features bundled`, and `--features "bundled-full session buildtime_bindgen"`.
-
-If running bindgen is problematic for you, `--features bundled-full` enables
-bundled and all features which don't require binding generation, and can be used
-instead.
-
-### Checklist
-
-- Run `cargo fmt` to ensure your Rust code is correctly formatted.
-- Ensure `cargo clippy --workspace --features bundled` passes without warnings.
-- Ensure `cargo clippy --workspace --features "bundled-full session buildtime_bindgen"` passes without warnings.
-- Ensure `cargo test --workspace --features bundled` reports no failures.
-- Ensure `cargo test --workspace --features "bundled-full session buildtime_bindgen"` reports no failures.

-## Author
-
-Rusqlite is the product of hard work by a number of people. A list is available
-here: https://github.com/rusqlite/rusqlite/graphs/contributors
-
-## Community
-
-Feel free to join the [Rusqlite Discord Server](https://discord.gg/nFYfGPB8g4) to discuss or get help with `rusqlite` or `libsqlite3-sys`.
-
-## License
-
-Rusqlite and libsqlite3-sys are available under the MIT license. See the LICENSE file for more info.
-
-### Licenses of Bundled Software
-
-Depending on the set of enabled cargo `features`, rusqlite and libsqlite3-sys will also bundle other libraries, which have their own licensing terms:
-
-- If `--features=bundled-sqlcipher` is enabled, the vendored source of [SQLcipher](https://github.com/sqlcipher/sqlcipher) will be compiled and statically linked in. SQLcipher is distributed under a BSD-style license, as described [here](libsqlite3-sys/sqlcipher/LICENSE).
-
-- If `--features=bundled` is enabled, the vendored source of SQLite will be compiled and linked in. SQLite is in the public domain, as described [here](https://www.sqlite.org/copyright.html).
-
-Both of these are quite permissive, have no bearing on the license of the code in `rusqlite` or `libsqlite3-sys` themselves, and can be entirely ignored if you do not use the feature in question.
-
-## Minimum supported Rust version (MSRV)
-
-Latest stable Rust version at the time of release. It might compile with older versions.

-//! Online SQLite backup API.
-//!
-//! Alternatively, you can create a backup with a simple
-//! [`VACUUM INTO <backup_path>`](https://sqlite.org/lang_vacuum.html#vacuuminto).
-//!
-//! To create a [`Backup`], you must have two distinct [`Connection`]s - one
-//! for the source (which can be used while the backup is running) and one for
-//! the destination (which cannot).  A [`Backup`] handle exposes three methods:
-//! [`step`](Backup::step) will attempt to back up a specified number of pages,
-//! [`progress`](Backup::progress) gets the current progress of the backup as of
-//! the last call to [`step`](Backup::step), and
-//! [`run_to_completion`](Backup::run_to_completion) will attempt to back up the
-//! entire source database, allowing you to specify how many pages are backed up
-//! at a time and how long the thread should sleep between chunks of pages.
-//!
-//! The following example is equivalent to "Example 2: Online Backup of a
-//! Running Database" from [SQLite's Online Backup API
-//! documentation](https://www.sqlite.org/backup.html).
-//!
-//! ```rust,no_run

-//! Incremental BLOB I/O.
-//!
-//! Note that SQLite does not provide API-level access to change the size of a
-//! BLOB; that must be performed through SQL statements.
-//!
-//! There are two choices for how to perform IO on a [`Blob`].
-//!
-//! 1. The implementations it provides of the `std::io::Read`, `std::io::Write`,
-//!    and `std::io::Seek` traits.
-//!
-//! 2. A positional IO API, e.g. [`Blob::read_at`], [`Blob::write_at`] and
-//!    similar.
-//!
-//! Documenting these in order:
-//!
-//! ## 1. `std::io` trait implementations.
-//!
-//! `Blob` conforms to `std::io::Read`, `std::io::Write`, and `std::io::Seek`,
-//! so it plays nicely with other types that build on these (such as
-//! `std::io::BufReader` and `std::io::BufWriter`). However, you must be careful
-//! with the size of the blob. For example, when using a `BufWriter`, the
-//! `BufWriter` will accept more data than the `Blob` will allow, so make sure
-//! to call `flush` and check for errors. (See the unit tests in this module for
-//! an example.)
-//!
-//! ## 2. Positional IO
-//!
-//! `Blob`s also offer a `pread` / `pwrite`-style positional IO api in the form
-//! of [`Blob::read_at`], [`Blob::write_at`], [`Blob::raw_read_at`],
-//! [`Blob::read_at_exact`], and [`Blob::raw_read_at_exact`].
-//!
-//! These APIs all take the position to read from or write to from as a
-//! parameter, instead of using an internal `pos` value.
-//!
-//! ### Positional IO Read Variants
-//!
-//! For the `read` functions, there are several functions provided:
-//!
-//! - [`Blob::read_at`]
-//! - [`Blob::raw_read_at`]
-//! - [`Blob::read_at_exact`]
-//! - [`Blob::raw_read_at_exact`]
-//!
-//! These can be divided along two axes: raw/not raw, and exact/inexact:
-//!
-//! 1. Raw/not raw refers to the type of the destination buffer. The raw
-//!    functions take a `&mut [MaybeUninit<u8>]` as the destination buffer,
-//!    where the "normal" functions take a `&mut [u8]`.
-//!
-//!    Using `MaybeUninit` here can be more efficient in some cases, but is
-//!    often inconvenient, so both are provided.
-//!
-//! 2. Exact/inexact refers to whether or not the entire buffer must be
-//!    filled in order for the call to be considered a success.
-//!
-//!    The "exact" functions require the provided buffer be entirely filled, or
-//!    they return an error, whereas the "inexact" functions read as much out of
-//!    the blob as is available, and return how much they were able to read.
-//!
-//!    The inexact functions are preferable if you do not know the size of the
-//!    blob already, and the exact functions are preferable if you do.
-//!
-//! ### Comparison to using the `std::io` traits:
-//!
-//! In general, the positional methods offer the following Pro/Cons compared to
-//! using the implementation `std::io::{Read, Write, Seek}` we provide for
-//! `Blob`:
-//!
-//! 1. (Pro) There is no need to first seek to a position in order to perform IO
-//!    on it as the position is a parameter.
-//!
-//! 2. (Pro) `Blob`'s positional read functions don't mutate the blob in any
-//!    way, and take `&self`. No `&mut` access required.
-//!
-//! 3. (Pro) Positional IO functions return `Err(rusqlite::Error)` on failure,
-//!    rather than `Err(std::io::Error)`. Returning `rusqlite::Error` is more
-//!    accurate and convenient.
-//!
-//!    Note that for the `std::io` API, no data is lost however, and it can be
-//!    recovered with `io_err.downcast::<rusqlite::Error>()` (this can be easy
-//!    to forget, though).
-//!
-//! 4. (Pro, for now). A `raw` version of the read API exists which can allow
-//!    reading into a `&mut [MaybeUninit<u8>]` buffer, which avoids a potential
-//!    costly initialization step. (However, `std::io` traits will certainly
-//!    gain this someday, which is why this is only a "Pro, for now").
-//!
-//! 5. (Con) The set of functions is more bare-bones than what is offered in
-//!    `std::io`, which has a number of adapters, handy algorithms, further
-//!    traits.
-//!
-//! 6. (Con) No meaningful interoperability with other crates, so if you need
-//!    that you must use `std::io`.
-//!
-//! To generalize: the `std::io` traits are useful because they conform to a
-//! standard interface that a lot of code knows how to handle, however that
-//! interface is not a perfect fit for [`Blob`], so another small set of
-//! functions is provided as well.
-//!
-//! # Example (`std::io`)
-//!
-//! ```rust
-//! # use rusqlite::blob::ZeroBlob;
-//! # use rusqlite::{Connection, MAIN_DB};
-//! # use std::error::Error;
-//! # use std::io::{Read, Seek, SeekFrom, Write};
-//! # fn main() -> Result<(), Box<dyn Error>> {
-//! let db = Connection::open_in_memory()?;
-//! db.execute_batch("CREATE TABLE test_table (content BLOB);")?;
-//!
-//! // Insert a BLOB into the `content` column of `test_table`. Note that the Blob
-//! // I/O API provides no way of inserting or resizing BLOBs in the DB -- this
-//! // must be done via SQL.
-//! db.execute("INSERT INTO test_table (content) VALUES (ZEROBLOB(10))", [])?;
-//!
-//! // Get the row id off the BLOB we just inserted.
-//! let rowid = db.last_insert_rowid();
-//! // Open the BLOB we just inserted for IO.
-//! let mut blob = db.blob_open(MAIN_DB, "test_table", "content", rowid, false)?;
-//!
-//! // Write some data into the blob. Make sure to test that the number of bytes
-//! // written matches what you expect; if you try to write too much, the data
-//! // will be truncated to the size of the BLOB.
-//! let bytes_written = blob.write(b"01234567")?;
-//! assert_eq!(bytes_written, 8);
-//!
-//! // Move back to the start and read into a local buffer.
-//! // Same guidance - make sure you check the number of bytes read!
-//! blob.seek(SeekFrom::Start(0))?;
-//! let mut buf = [0u8; 20];
-//! let bytes_read = blob.read(&mut buf[..])?;
-//! assert_eq!(bytes_read, 10); // note we read 10 bytes because the blob has size 10
-//!
-//! // Insert another BLOB, this time using a parameter passed in from
-//! // rust (potentially with a dynamic size).
-//! db.execute(
-//!     "INSERT INTO test_table (content) VALUES (?1)",
-//!     [ZeroBlob(64)],
-//! )?;
-//!
-//! // given a new row ID, we can reopen the blob on that row
-//! let rowid = db.last_insert_rowid();
-//! blob.reopen(rowid)?;
-//! // Just check that the size is right.
-//! assert_eq!(blob.len(), 64);
-//! # Ok(())
-//! # }
-//! ```
-//!
