story-kit: queue 245_bug_chat_history_persistence_lost_on_page_refresh_story_145_regression for merge

run_command_with_timeout piped stdout/stderr but only read them after
the child exited. When test output exceeded the 64KB OS pipe buffer,
the child blocked on write() while the parent blocked on waitpid() —
a permanent deadlock that caused every merge pipeline to hang.

Drain both pipes in background threads so the buffers never fill.

+
+## User Story
+
+As a user, I want to receive bot notifications with an error icon in the channel whenever a story errors out (e.g. merge failure), so that I'm immediately aware of problems.
+
+## Design Constraint
+
+Story 261 adds stage-transition notifications using the same Matrix messaging path. Extract a shared utility/module for sending Matrix messages so that both error notifications (this story) and stage-transition notifications (261) use the same code path. Do not duplicate Matrix message-sending logic.
+
+## Acceptance Criteria
+
+- [ ] Bot sends an error notification to the channel when a story encounters a failure (e.g. merge failure)
+- [ ] Notification includes an error icon to distinguish it from normal stage-transition notifications
+- [ ] Notification includes the story number, name, and a description of the error
+- [ ] Matrix message-sending logic is in a shared module usable by both error and stage-transition notifications
+
+## Out of Scope

+# Bug 245: Chat history persistence lost on page refresh (story 145 regression)
+
+## Description
+
+Story 145 implemented localStorage persistence for chat history across page reloads. This is no longer working — refreshing the page loses all conversation context. This is a regression of the feature delivered in story 145.
+
+## How to Reproduce
+
+1. Open the web UI and have a conversation with the agent
+2. Refresh the page (F5 or Cmd+R)
+3. Send a new message
+4. The LLM has no knowledge of the prior conversation
+
+## Actual Result
+
+Chat history is gone after refresh — the UI shows a blank conversation. Even if messages appear in the UI (loaded from localStorage), the LLM does not receive them as context on the next exchange.
+
+## Expected Result
+
+Chat history is restored from localStorage on page load, as implemented in story 145. The LLM should receive the full conversation history when the user sends a new message after refresh.
+
+## Acceptance Criteria
+
+- [ ] Chat messages survive a full page refresh (visible in UI)
+- [ ] Chat messages are restored from localStorage on component mount
+- [ ] After refresh, the LLM receives full prior conversation history as context when the user sends the next message
+- [ ] Behaviour matches the original acceptance criteria from story 145
+
+## Investigation Notes (2026-03-17)
+
+### Root cause analysis
+
+The frontend correctly:
+1. Persists messages to localStorage in `useChatHistory.ts` (key: `storykit-chat-history:{projectPath}`)
+2. Loads them on mount
+3. Sends the FULL history array to the backend via `wsRef.current?.sendChat(newHistory, config)` in `Chat.tsx` line ~558
+
+The backend bug is in `server/src/llm/chat.rs`:
+- The `chat()` function receives the full `messages: Vec<Message>` from the client
+- Line ~283: `let mut current_history = messages.clone()` — correctly clones full history
+- Lines ~299-318: Adds 2 system prompts at position 0 and 1
+- Lines ~323-404: Main LLM loop generates new assistant/tool messages
+- **Line ~407: `ChatResult { messages: new_messages }` — BUG: returns ONLY the newly generated turn, not the full `current_history`**
+
+During streaming, the `on_update()` callbacks DO send `current_history[2..]` (full history minus system prompts), which is correct. But there may be a reconciliation issue on the frontend where the final state doesn't include the full history.
+
+### Key files
+- `frontend/src/hooks/useChatHistory.ts` — localStorage persistence
+- `frontend/src/components/Chat.tsx` — sends full history, handles `onUpdate` callbacks
+- `frontend/src/api/client.ts` — WebSocket client
+- `server/src/http/ws.rs` — WebSocket handler, passes messages to chat()
+- `server/src/llm/chat.rs` — **THE BUG** at line ~407, ChatResult returns only new_messages
+
+### What NOT to do
+- Do NOT layer on a new localStorage implementation. The localStorage code works fine.
+- Do NOT add server-side persistence. The "dumb pipe" architecture is correct.
+- The fix should be surgical — ensure the full conversation history round-trips correctly through the backend.

+
+## User Story
+
+As a Matrix user messaging the bot, I want the bot to correctly recognize my cross-signing-verified devices, so that my messages are not rejected when I have a valid verified identity.
+
+## Acceptance Criteria
+
+- [ ] The bot's `check_sender_verified` function (or equivalent) verifies the sender's identity trust status, not just individual device verification
+- [ ] When @yossarian:crashlabs.io (who has valid cross-signing keys) sends a message in an encrypted room, the bot accepts it instead of rejecting with 'no cross-signing-verified device found'

+# Bug 258: Auto-assign not called after merge failure
+
+## Description
+
+When the background merge pipeline fails (e.g. quality gate timeout), `auto_assign_available_work` is never called. The story stays in `4_merge/` with no agent assigned, requiring manual intervention.
+
+### Root cause
+
+In `pool.rs`, `start_merge_agent_work` spawns a tokio task that calls `run_merge_pipeline`. On failure, the task updates the job status to `Failed` but does NOT call `auto_assign_available_work`. The only call to `auto_assign` in the merge pipeline is inside `run_merge_pipeline` on the success path (line ~1251).
+
+The `spawn_pipeline_advance` completion handler does call `auto_assign` after the mergemaster agent exits, but only on the success path (post-merge tests pass → move to done → auto_assign). On failure, it returns early without triggering auto-assign.
+
+There is no periodic sweep — auto-assign is purely reactive (watcher events, agent completions, startup).
+
+### Impact
+
+After a merge failure, the story is permanently stuck in `4_merge/` with no agent. The only way to unstick it is to restart the server or manually trigger a watcher event.
+
+## Acceptance Criteria
+
+- [ ] After a merge pipeline failure, `auto_assign_available_work` is called so the mergemaster can retry
+- [ ] Stories in `4_merge/` do not get permanently stuck after transient merge failures

+# 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.
+
+A previous manual attempt to upgrade failed on compile, so the agent should investigate compatibility with our current `matrix-sdk-sqlite` dependency and resolve any breaking changes.
+
+## Acceptance Criteria
+
+- [ ] `libsqlite3-sys` is upgraded to `0.37.0`
+- [ ] `cargo build` succeeds
+- [ ] All tests pass

+The mergemaster merge pipeline consistently fails at the cherry-pick step with: fatal: bad revision merge-queue/{story_id}. The merge-queue branch is created and the squash commit succeeds, but the branch reference is not accessible during the subsequent cherry-pick onto master.

+
+## How to Reproduce
+
+1. Have a completed story in 4_merge/ with a feature branch containing commits ahead of master
+2. Trigger merge_agent_work via MCP or let the mergemaster agent run
+3. Observe the cherry-pick failure

+## Acceptance Criteria

+# Bug 251: Archive sweep not moving stories from done to archived
+
+## Description
+
+Stories that have been in `5_done/` for well over the configured retention period (default 4 hours) are not being automatically swept to `6_archived/`. Items from March 14 are still sitting in `5_done/` as of March 16 — over 2 days past the threshold. The last items that successfully reached `6_archived/` date from Feb 23-24.
+
+Additionally, story file moves (e.g. from one pipeline stage to another) are sometimes not being auto-committed, which used to work.
+
+## How to Reproduce
+
+1. Start the Story Kit server
+2. Move a story to `5_done/`
+3. Wait longer than `done_retention_secs` (default 14400 seconds / 4 hours)
+4. Observe that the story is never moved to `6_archived/`
+
+## Actual Result
+
+Stories remain in `5_done/` indefinitely. No sweep log messages appear in the server output.
+
+## Expected Result
+
+Stories older than `done_retention_secs` are automatically moved to `6_archived/` and the move is auto-committed.
+
+## Investigation Notes
+
+The sweep logic lives in `server/src/io/watcher.rs` around line 208 (`sweep_done_to_archived()`). The watcher runs on a dedicated OS thread (line 310) with a timer-based sweep interval (line 441, default 60s).
+
+**Do NOT layer new code on top of this.** Use `git bisect` or `git log` to find when the sweep stopped working. The code looks structurally correct — the watcher thread may be dying silently with no restart mechanism, or something changed in how/when the sweep is triggered. Find the root cause and fix it there.

+# Bug 253: Watcher and auto-assign do not reinitialize when project root changes
+
+## Description
+
+When the server starts, if the frontend opens the project at the wrong path (e.g. server/ subdirectory instead of project root), the filesystem watcher and auto-assign run against that wrong path. When the frontend corrects itself by calling DELETE /project then open_project with the right path, the watcher and auto-assign do not reinitialize. This means:
+
+1. The filesystem watcher watches the wrong directory for the entire session
+2. Auto-assign only runs once at startup (against the wrong root) and never re-runs
+3. Stories placed in 2_current/ are never auto-assigned to coders
+4. The archive sweep never fires (same watcher thread)
+
+This is likely the root cause of bug 251 (archive sweep not working) and explains why coders are not being auto-assigned.
+
+## How to Reproduce
+
+1. Start the Story Kit server\n2. Open a project in the frontend — note the first open_project sets project_root to the wrong subdirectory\n3. Frontend corrects by calling DELETE /project then open_project with the correct path\n4. Move a story into 2_current/\n5. Observe that no coder is auto-assigned
+
+## Actual Result
+
+Watcher and auto-assign remain bound to the initial (wrong) project root. No filesystem events are detected for the correct project directory. Stories in 2_current/ are never picked up.
+
+## Expected Result
+
+When project_root changes via open_project, the watcher thread should be stopped and restarted against the new root, and auto_assign_available_work() should re-run.
+
+## Acceptance Criteria
+
+- [ ] When open_project is called with a new path, the filesystem watcher restarts watching the new project root
+- [ ] auto_assign_available_work() re-runs after a project root change
+- [ ] If DELETE /project is called, the watcher stops (no zombie watcher on a stale path)
+- [ ] Stories in 2_current/ are auto-assigned after the project root is corrected

+
+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.

+
+## 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
+//! # use rusqlite::{backup, Connection, Result};
+//! # use std::path::Path;

+//!     src: &Connection,
+//!     dst: P,
+//!     progress: fn(backup::Progress),
+//! ) -> Result<()> {
+//!     let mut dst = Connection::open(dst)?;
+//!     let backup = backup::Backup::new(src, &mut dst)?;
+//!     backup.run_to_completion(5, time::Duration::from_millis(250), Some(progress))

+//! 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(())
+//! # }
+//! ```
