+# 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 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

+
+## User Story
+
+As a Matrix room participant, I want the bot's messages to not show "encrypted by a device not verified by its owner" warnings, so that I have confidence the bot's encryption is fully verified.
+
+## Acceptance Criteria
+
+- [ ] At startup the bot checks whether its own device keys have been self-signed (cross-signed by its own user identity)
+- [ ] If the device keys are not self-signed, the bot signs them automatically
+- [ ] After signing, the bot uploads the new signatures to the homeserver
+- [ ] After a clean start (fresh matrix_store / device_id) the bot's messages no longer show the 'encrypted by a device not verified by its owner' warning

+
+# 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

-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).
-//!

-//! 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(())
-//! # }
-//! ```
-//!

-/// Trait used for [sets of parameter][params] passed into SQL
-/// statements/queries.
-///
-/// [params]: https://www.sqlite.org/c3ref/bind_blob.html
-///
-/// Note: Currently, this trait can only be implemented inside this crate.
-/// Additionally, it's methods (which are `doc(hidden)`) should currently not be
-/// considered part of the stable API, although it's possible they will
-/// stabilize in the future.
-///
-/// # Passing parameters to SQLite
-///
-/// Many functions in this library let you pass parameters to SQLite. Doing this
-/// lets you avoid any risk of SQL injection, and is simpler than escaping
-/// things manually. Aside from deprecated functions and a few helpers, this is
-/// indicated by the function taking a generic argument that implements `Params`
-/// (this trait).
-///
-/// ## Positional parameters
-///
-/// For cases where you want to pass a list of parameters where the number of
-/// parameters is known at compile time, this can be done in one of the
-/// following ways:
-///
-/// - For small lists of parameters up to 16 items, they may alternatively be
-///   passed as a tuple, as in `thing.query((1, "foo"))`.
-///   This is somewhat inconvenient for a single item, since you need a
-///   weird-looking trailing comma: `thing.query(("example",))`. That case is
-///   perhaps more cleanly expressed as `thing.query(["example"])`.
-///
-/// - Using the [`rusqlite::params!`](crate::params!) macro, e.g.
-///   `thing.query(rusqlite::params![1, "foo", bar])`. This is mostly useful for
-///   heterogeneous lists where the number of parameters greater than 16, or
-///   homogeneous lists of parameters where the number of parameters exceeds 32.
-///
-/// - For small homogeneous lists of parameters, they can either be passed as:
-///
-///     - an array, as in `thing.query([1i32, 2, 3, 4])` or `thing.query(["foo",
-///       "bar", "baz"])`.
-///
-///     - a reference to an array of references, as in `thing.query(&["foo",
-///       "bar", "baz"])` or `thing.query(&[&1i32, &2, &3])`.
-///       (Note: in this case we don't implement this for slices for coherence
-///       reasons, so it really is only for the "reference to array" types —
-///       hence why the number of parameters must be <= 32, or you need to
-///       reach for `rusqlite::params!`)
-///
-///   Unfortunately, in the current design it's not possible to allow this for
-///   references to arrays of non-references (e.g. `&[1i32, 2, 3]`). Code like
-///   this should instead either use `params!`, an array literal, a `&[&dyn
-///   ToSql]` or if none of those work, [`ParamsFromIter`].
-///
-/// - As a slice of `ToSql` trait object references, e.g. `&[&dyn ToSql]`. This
-///   is mostly useful for passing parameter lists around as arguments without
-///   having every function take a generic `P: Params`.
-///
-/// ### Example (positional)
-///
-/// ```rust,no_run
-/// # use rusqlite::{Connection, Result, params};
-/// fn update_rows(conn: &Connection) -> Result<()> {
-///     let mut stmt = conn.prepare("INSERT INTO test (a, b) VALUES (?1, ?2)")?;
-///
-///     // Using a tuple:
-///     stmt.execute((0, "foobar"))?;
-///
-///     // Using `rusqlite::params!`:
-///     stmt.execute(params![1i32, "blah"])?;
-///
-///     // array literal — non-references
-///     stmt.execute([2i32, 3i32])?;
-///
-///     // array literal — references
-///     stmt.execute(["foo", "bar"])?;
-///
-///     // Slice literal, references:
-///     stmt.execute(&[&2i32, &3i32])?;
-///
-///     // Note: The types behind the references don't have to be `Sized`
-///     stmt.execute(&["foo", "bar"])?;
-///
-///     // However, this doesn't work (see above):
-///     // stmt.execute(&[1i32, 2i32])?;
-///     Ok(())
-/// }
-/// ```
-///
-/// ## Named parameters
-///
-/// SQLite lets you name parameters using a number of conventions (":foo",
-/// "@foo", "$foo"). You can pass named parameters in to SQLite using rusqlite
-/// in a few ways:
-///
-/// - Using the [`rusqlite::named_params!`](crate::named_params!) macro, as in
-///   `stmt.execute(named_params!{ ":name": "foo", ":age": 99 })`. Similar to
-///   the `params` macro, this is most useful for heterogeneous lists of
-///   parameters, or lists where the number of parameters exceeds 32.
-///
-/// - As a slice of `&[(&str, &dyn ToSql)]`. This is what essentially all of
-///   these boil down to in the end, conceptually at least. In theory, you can
-///   pass this as `stmt`.
-///
-/// - As array references, similar to the positional params. This looks like
-///   `thing.query(&[(":foo", &1i32), (":bar", &2i32)])` or
-///   `thing.query(&[(":foo", "abc"), (":bar", "def")])`.
-///
-/// Note: Unbound named parameters will be left to the value they previously
-/// were bound with, falling back to `NULL` for parameters which have never been
-/// bound.
-///
-/// ### Example (named)
-///
-/// ```rust,no_run
-/// # use rusqlite::{Connection, Result, named_params};
-/// fn insert(conn: &Connection) -> Result<()> {
-///     let mut stmt = conn.prepare("INSERT INTO test (key, value) VALUES (:key, :val)")?;
-///     // Using `rusqlite::params!`:
-///     stmt.execute(named_params! { ":key": "one", ":val": 2 })?;
-///     // Alternatively:
-///     stmt.execute(&[(":key", "three"), (":val", "four")])?;
-///     // Or:
-///     stmt.execute(&[(":key", &100), (":val", &200)])?;
-///     Ok(())
-/// }
-/// ```
-///
-/// ## No parameters
-///
-/// You can just use an empty tuple or the empty array literal to run a query
-/// that accepts no parameters.
-///
-/// ### Example (no parameters)
-///
-/// The empty tuple:
-///
-/// ```rust,no_run
-/// # use rusqlite::{Connection, Result, params};
-/// fn delete_all_users(conn: &Connection) -> Result<()> {
-///     // You may also use `()`.
-///     conn.execute("DELETE FROM users", ())?;
-///     Ok(())
-/// }
-/// ```
-///
-/// The empty array:
-///
-/// ```rust,no_run
-/// # use rusqlite::{Connection, Result, params};
-/// fn delete_all_users(conn: &Connection) -> Result<()> {
-///     // Just use an empty array (e.g. `[]`) for no params.
-///     conn.execute("DELETE FROM users", [])?;
-///     Ok(())
-/// }
-/// ```
-///
-/// ## Dynamic parameter list
-///
-/// If you have a number of parameters which is unknown at compile time (for
-/// example, building a dynamic query at runtime), you have two choices:
-///
-/// - Use a `&[&dyn ToSql]`. This is often annoying to construct if you don't
-///   already have this type on-hand.
-/// - Use the [`ParamsFromIter`] type. This essentially lets you wrap an
-///   iterator some `T: ToSql` with something that implements `Params`. The
-///   usage of this looks like `rusqlite::params_from_iter(something)`.
-///
-/// A lot of the considerations here are similar either way, so you should see
-/// the [`ParamsFromIter`] documentation for more info / examples.

-/// Adapter type which allows any iterator over [`ToSql`] values to implement

-///
-/// This essentially is only ever actually needed when dynamically generating
-/// SQL — static SQL (by definition) has the number of parameters known
-/// statically. As dynamically generating SQL is itself pretty advanced, this
-/// API is itself for advanced use cases (See "Realistic use case" in the
-/// examples).
-///
-/// # Example
-///
-/// ## Basic usage
-///
-/// ```rust,no_run
-/// use rusqlite::{params_from_iter, Connection, Result};
-/// use std::collections::BTreeSet;
-///
-/// fn query(conn: &Connection, ids: &BTreeSet<String>) -> Result<()> {
-///     assert_eq!(ids.len(), 3, "Unrealistic sample code");
-///
-///     let mut stmt = conn.prepare("SELECT * FROM users WHERE id IN (?1, ?2, ?3)")?;
-///     let _rows = stmt.query(params_from_iter(ids.iter()))?;
-///
-///     // use _rows...
-///     Ok(())
-/// }
-/// ```
-///
-/// ## Realistic use case
-///
-/// Here's how you'd use `ParamsFromIter` to call [`Statement::exists`] with a
-/// dynamic number of parameters.
-///
-/// ```rust,no_run
-/// use rusqlite::{Connection, Result};
-///
-/// pub fn any_active_users(conn: &Connection, usernames: &[String]) -> Result<bool> {
-///     if usernames.is_empty() {
-///         return Ok(false);
-///     }
-///
-///     // Note: `repeat_vars` never returns anything attacker-controlled, so
-///     // it's fine to use it in a dynamically-built SQL string.
-///     let vars = repeat_vars(usernames.len());
-///
-///     let sql = format!(
-///         // In practice this would probably be better as an `EXISTS` query.
-///         "SELECT 1 FROM user WHERE is_active AND name IN ({}) LIMIT 1",
-///         vars,
-///     );
-///     let mut stmt = conn.prepare(&sql)?;
-///     stmt.exists(rusqlite::params_from_iter(usernames))
-/// }
-///
-/// // Helper function to return a comma-separated sequence of `?`.
-/// // - `repeat_vars(0) => panic!(...)`
-/// // - `repeat_vars(1) => "?"`
-/// // - `repeat_vars(2) => "?,?"`
-/// // - `repeat_vars(3) => "?,?,?"`
-/// // - ...
-/// fn repeat_vars(count: usize) -> String {
-///     assert_ne!(count, 0);
-///     let mut s = "?,".repeat(count);
-///     // Remove trailing comma
-///     s.pop();
-///     s
-/// }
-/// ```
-///
-/// That is fairly complex, and even so would need even more work to be fully
-/// production-ready:
-///
-/// - production code should ensure `usernames` isn't so large that it will
-///   surpass [`conn.limit(Limit::SQLITE_LIMIT_VARIABLE_NUMBER)`][limits],
-///   chunking if too large. (Note that the limits api requires rusqlite to have
-///   the "limits" feature).
-///
-/// - `repeat_vars` can be implemented in a way that avoids needing to allocate
-///   a String.
-///
-/// - Etc...
-///
-/// [limits]: crate::Connection::limit
-///
-/// This complexity reflects the fact that `ParamsFromIter` is mainly intended
-/// for advanced use cases — most of the time you should know how many
-/// parameters you have statically (and if you don't, you're either doing
-/// something tricky, or should take a moment to think about the design).

-//! Traits dealing with SQLite data types.
-//!
-//! SQLite uses a [dynamic type system](https://www.sqlite.org/datatype3.html). Implementations of
-//! the [`ToSql`] and [`FromSql`] traits are provided for the basic types that
-//! SQLite provides methods for:
-//!
-//! * Strings (`String` and `&str`)
-//! * Blobs (`Vec<u8>` and `&[u8]`)
-//! * Numbers
-//!
-//! The number situation is a little complicated due to the fact that all
-//! numbers in SQLite are stored as `INTEGER` (`i64`) or `REAL` (`f64`).
-//!
-//! [`ToSql`] and [`FromSql`] are implemented for all primitive number types.
-//! [`FromSql`] has different behaviour depending on the SQL and Rust types, and
-//! the value.
-//!
-//! * `INTEGER` to integer: returns an
-//!   [`Error::IntegralValueOutOfRange`](crate::Error::IntegralValueOutOfRange)
-//!   error if the value does not fit in the Rust type.
-//! * `REAL` to integer: always returns an
-//!   [`Error::InvalidColumnType`](crate::Error::InvalidColumnType) error.
-//! * `INTEGER` to float: casts using `as` operator. Never fails.
-//! * `REAL` to float: casts using `as` operator. Never fails.
-//!
-//! [`ToSql`] always succeeds except when storing a `u64` or `usize` value that
-//! cannot fit in an `INTEGER` (`i64`). Also note that SQLite ignores column
-//! types, so if you store an `i64` in a column with type `REAL` it will be
-//! stored as an `INTEGER`, not a `REAL` (unless the column is part of a
-//! [STRICT table](https://www.sqlite.org/stricttables.html)).
-//!
-//! If the `time` feature is enabled, implementations are
-//! provided for `time::OffsetDateTime` that use the RFC 3339 date/time format,
-//! `"%Y-%m-%dT%H:%M:%S.%fZ"`, to store time values as strings.  These values
-//! can be parsed by SQLite's builtin
-//! [datetime](https://www.sqlite.org/lang_datefunc.html) functions.  If you
-//! want different storage for datetimes, you can use a newtype.
-#![cfg_attr(
-    feature = "time",
-    doc = r##"
-For example, to store datetimes as `i64`s counting the number of seconds since
-the Unix epoch:
-
-```
-use rusqlite::types::{FromSql, FromSqlError, FromSqlResult, ToSql, ToSqlOutput, ValueRef};
-use rusqlite::Result;
-
-pub struct DateTimeSql(pub time::OffsetDateTime);
-
-impl FromSql for DateTimeSql {

-        i64::column_result(value).and_then(|as_i64| {
-            time::OffsetDateTime::from_unix_timestamp(as_i64)
-            .map(|odt| DateTimeSql(odt))
-            .map_err(FromSqlError::other)
-        })

-        Ok(self.0.unix_timestamp().into())

-//! [`ToSql`] and [`FromSql`] are also implemented for `Option<T>` where `T`
-//! implements [`ToSql`] or [`FromSql`] for the cases where you want to know if
-//! a value was NULL (which gets translated to `None`).
