 When fixing a bug, edit `unit-regression3.cpp` and add a section referencing the fixed issue.
 `unit-regression2.cpp` holds the older tests; the two files exist because a single one grew large enough for the
 MinGW linker to fail relocating it, so please keep adding to the smaller file rather than growing the larger one.
+Tests that call `sax_parse` go into `unit-sax_parse.cpp` rather than into a large test file: every call instantiates

-
-The [Natvis](https://learn.microsoft.com/en-us/visualstudio/debugger/create-custom-views-of-native-objects) file that
-gives `json` values a friendly view in the Visual Studio debugger. The file is generated by
-`tools/generate_natvis/generate_natvis.py` from the template `tools/generate_natvis/nlohmann_json.natvis.j2` and the ABI
-tags and version in `include/nlohmann/detail/abi_macros.hpp`; change the script or the template rather than editing
-the file by hand. The file can be updated by calling
-
-```shell
-make natvis
-```
-
-The "Check amalgamation" workflow fails if the file is out of date.
-
-The file covers the namespace variants with up to two ABI tags. A Natvis file for other configurations can be
-generated with the `--abi-tags` or `--all` options, for example
-`make natvis NATVIS_ARGS="--abi-tags _diag,_dp,_vns --output my_nlohmann_json.natvis"`; see
-[`tools/generate_natvis`](tools/generate_natvis/README.md). With MSVC, CMake adds the file to the `nlohmann_json`
-target and installs it.

-
-Creates a [JSON Merge Patch](https://tools.ietf.org/html/rfc7396) so that value `source` can be changed into the value
-`target` by calling the [`merge_patch`](merge_patch.md) function. The patch contains only what differs: changed and
-added members with their new values, and removed members with the value `#!json null`. Nested objects are compared
-member by member; any other value that differs, including an array, is replaced as a whole.
-
-For two JSON values `source` and `target`, where `target` contains no object member whose value is `#!json null`, the
-following code always yields `#!cpp true` (for [`ordered_json`](../ordered_json.md), see the notes below):
-```cpp
-basic_json patched = source;
-patched.merge_patch(merge_diff(source, target));
-patched == target;
-```
-
-## Parameters
-
-`source` (in)
-:   JSON value to compare from
-
-`target` (in)
-:   JSON value to compare against
-
-## Return value
-
-a JSON Merge Patch to convert the `source` to `target`
-
-## Exception safety
-
-Strong guarantee: `source` and `target` are never modified.
-
-## Complexity
-
-Linear in the total number of values (including nested ones) in `source` and `target`, times the cost of a key-based
-object operation (looking up a key, or adding one to the patch): logarithmic for [`json`](../json.md), and linear for
-[`ordered_json`](../ordered_json.md) (see [`ordered_map` complexity](../ordered_map.md#complexity)). For
-`ordered_json`, diffing two objects with `n` and `m` members therefore takes O((n+m)²).
-
-## Notes
-
-- A merge patch uses `#!json null` to remove a member, so it cannot set a member to `#!json null`. As in RFC 7396, a
-  `#!json null` member of `target` is treated as absent: the patch removes the member from `source` instead of setting
-  it to `#!json null`. A member that is `#!json null` in both `source` and `target` is unchanged and left out of the
-  patch, so `source` keeps it.
-- A merge patch cannot reorder object members, and [`merge_patch`](merge_patch.md) appends added members at the end.
-  For [`ordered_json`](../ordered_json.md), the patched value therefore has the same members as `target`, but not
-  necessarily in the same order, and may compare unequal to it. The patch lists changed and removed members in the
-  order of `source`, followed by added members in the order of `target`.

 1. 3-way compares two JSON values producing a result of type `std::partial_ordering` according to the following rules:
     - Two JSON values compare with a result of `std::partial_ordering::unordered` if either value is discarded.
     - If both JSON values are of the same type, the result is produced by 3-way comparing their stored values using
       their respective `operator<=>`.

-!!! tip "Parsing into a document instead of a value"
-
-    [`basic_json_document::parse`](../basic_json_document/parse.md) accepts the same inputs and the same options, but
-    keeps the result as a flat index of the parsed values instead of a tree of `basic_json` values. It is faster and uses
-    less memory when only parts of the document are read, and it also accepts a pointer to a null-terminated wide string,
-    which `parse()` does not. See [Zero-copy JSON views](../../features/json_view.md).
-
-!!! tip "Performance"
-
-    Contiguous inputs (strings, string views, vectors, arrays, pointer ranges) are the fastest to parse. A
-    `#!cpp std::istream` comes close: the parser scans the characters its stream buffer holds in bulk, without reading
-    ahead, so the stream is left exactly where it would be after reading one character at a time. A `#!cpp FILE*` is
-    read one character at a time, but the file is locked only once, so other threads that use the same `FILE` object
-    wait until parsing is done. See [input sources and performance](../../features/parsing/index.md#input-sources-and-performance),
