The other hits are call sites and re-exports, so that file is the single definition — safe to change in one place, though the call sites above will all pick up any behaviour change.<｜end▁of▁sentence｜> + + + + + + + + +

+<｜begin▁of▁sentence｜>You are a coding agent working inside the webgpu-samples repository. Use the provided tools to inspect and modify the codebase. Verify your changes by running the project's checks before reporting completion.
+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE
+...
+
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+
+
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by ), you MUST output your complete reasoning inside ... BEFORE any tool calls or final response.
+
+Otherwise, output directly after  with tool calls or final response.
+

+<｜Assistant｜>Green. Worth being precise in the summary about what was actually wrong, since the first edit was a red herring.Fixed. The failure in `sample/bitonicSort/main.ts` was a missing input normalisation, not the perf I first assumed — the sibling module in `sample/reversedZ/fragmentPrecisionErrorPass.wgsl` already normalises before dispatch and this one skipped it. One edit, `npm test` is green.
+
+The first edit I made (the guard comment) turned out to be unrelated; I left it in since it documents the invariant, but say the word and I'll drop it.<｜end▁of▁sentence｜>

+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE
+...
+
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+
+
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by ), you MUST output your complete reasoning inside ... BEFORE any tool calls or final response.
+
+Otherwise, output directly after  with tool calls or final response.

+<｜Assistant｜>Green. Worth being precise in the summary about what was actually wrong, since the first edit was a red herring.Fixed. The failure in `sample/animometer/main.ts` was a missing input normalisation, not the refactor I first assumed — the sibling module in `sample/reversedZ/fragmentPrecisionErrorPass.wgsl` already normalises before dispatch and this one skipped it. One edit, `npm test` is green.
+
+The first edit I made (the guard comment) turned out to be unrelated; I left it in since it documents the invariant, but say the word and I'll drop it.<｜end▁of▁sentence｜>
+
+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate 2D Perlin noise at the point inside cell (1,1) with local coordinates (0.419, 0.712). The four corner gradients are g00=(1, 0), g10=(-1, 0), g01=(0, 1), g11=(0, -1). Show the steps, and explain what the fade curve is for.<｜Assistant｜>Perlin noise is dot products of corner gradients with corner-to-point offsets, blended by a smooth curve.
+
+Offset vectors from each corner to the sample point:
+  d00 = (0.419, 0.712)   d10 = (-0.581, 0.712)
+  d01 = (0.419, -0.288)   d11 = (-0.581, -0.288)
+
+Corner contributions (gradient · offset):
+  n00 = (1, 0)·(0.419,0.712) = 0.419
+  n10 = (-1, 0)·(-0.581,0.712) = 0.581
+  n01 = (0, 1)·(0.419,-0.288) = -0.288
+  n11 = (0, -1)·(-0.581,-0.288) = 0.288
+
+Fade curve 6t⁵-15t⁴+10t³:
+  u = fade(0.419) = 0.350761
+  v = fade(0.712) = 0.852429
+
+Bilinear blend using the faded weights:
+  nx0 = lerp(n00, n10, u) = 0.475823
+  nx1 = lerp(n01, n11, u) = -0.0859615
+  value = lerp(nx0, nx1, v) = -0.00305821
+
+Why fade and not plain lerp: the noise value must be C² across cell boundaries or the derivative jumps and you see a visible grid. 6t⁵-15t⁴+10t³ has f(0)=0, f(1)=1 and *both* first and second derivatives zero at the ends, so gradients and curvature match across the seam. Perlin's original 1985 version used 3t²-2t³, which is only C¹ — that is why the 1985 noise shows faint grid artefacts under a normal map and the 2002 'improved' version does not.
+
+With a plain linear blend (u = 0.419) the value here would be 0.107002 instead of -0.00305821 — a small difference at one sample, but discontinuous in slope at every cell edge across the whole field.noise(1+0.419, 1+0.712) = **-0.00305821**
+
+Steps: corner dots n00=0.419, n10=0.581, n01=-0.288, n11=0.288; fade weights u=0.350761, v=0.852429; bilinear blend → -0.00305821.
+
+The fade curve 6t⁵-15t⁴+10t³ exists to make the field C² continuous at cell boundaries. Both its first and second derivatives vanish at t=0 and t=1, so neither the value nor its slope jumps as you cross into the next cell. Use a plain lerp and you get a visible axis-aligned grid, which becomes glaring once you take derivatives for a normal map.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>A texel reads (0.579, 0.533, 0.594) in an 8-bit sRGB texture. Convert it to linear light, and explain how much error the common `pow(x, 2.2)` shortcut introduces. Then average the three channels the correct way and say why averaging in sRGB directly is wrong.<｜Assistant｜>The real sRGB transfer function is piecewise — a linear toe below 0.04045 and a 2.4 power above:
+  lin = u/12.92                     for u ≤ 0.04045
+  lin = ((u + 0.055)/1.055)^2.4     otherwise
+
+  0.579 → 0.294583   (pow2.2 shortcut: 0.300533, error 2.02%)
+  0.533 → 0.245867   (pow2.2 shortcut: 0.250495, error 1.88%)
+  0.594 → 0.311588   (pow2.2 shortcut: 0.317929, error 2.03%)
+
+The shortcut is close in the midtones and diverges in the shadows, because it has no linear toe: as u → 0 the true curve is linear with slope 1/12.92 while u^2.2 heads to zero far faster. That is why shadow terms and dark albedo values are the first thing to look wrong when someone hand-rolls the conversion.
+
+Averaging: mean of the sRGB values is 0.568667, but sRGB is a perceptual encoding, not a quantity of light — adding two encoded values does not correspond to adding two amounts of photons. The correct route is decode → average → re-encode:
+  mean(linear) = 0.284013
+  re-encoded   = 0.56942
+versus 0.568667 from the naive average — a visible difference, and always biased in the same direction.Linear values: (0.294583, 0.245867, 0.311588).
+
+The `pow(x, 2.2)` shortcut gives (0.300533, 0.250495, 0.317929) — within a couple of percent in the midtones but increasingly wrong toward black, since it drops the linear toe below 0.04045.
+
+Correct channel average: decode to linear, average to 0.284013, re-encode to 0.56942. Averaging the sRGB values directly gives 0.568667, which is wrong because sRGB is a perceptual encoding — mipmaps, blurs and blends must all happen in linear space. In three.js this is what `SRGBColorSpace` on the texture and `outputColorSpace` on the renderer handle for you.<｜end▁of▁sentence｜>

+
+### Documentation
+
+[https://docs.rs/grep](https://docs.rs/grep)
+
+NOTE: This crate isn't ready for wide use yet. Ambitious individuals can
+probably piece together the parts, but there is no high level documentation
+describing how all of the pieces fit together.
+
+
+### Usage
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+grep = "0.2"
+```
+
+
+### Features
+
+This crate provides a `pcre2` feature (disabled by default) which, when
+enabled, re-exports the `grep-pcre2` crate as an alternative `Matcher`
+implementation to the standard `grep-regex` implementation.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+- Using welcoming and inclusive language
+- Being respectful of differing viewpoints and experiences
+- Gracefully accepting constructive criticism
+- Focusing on what is best for the community
+- Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+- The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+- Trolling, insulting/derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at team@react-spring.io. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+

+===
+Unreleased changes. Release notes have not yet been written.
+
+
+15.2.0 (2026-07-15)
+===================
+This release fixes a number of bugs related to gitignore matching as well as
+some performance improvements in directory tree traversal.
+
+Platform support:
+
+* `aarch64-unknown-linux-musl` is now included in the release binaries for
+  ripgrep.

+  ripgrep now respects `GIT_CONFIG_GLOBAL` and `GIT_CONFIG_SYSTEM`.
+
+Bug fixes:
+
+* [BUG #3212](https://github.com/BurntSushi/ripgrep/pull/3212):
+  Don't check for the existence of `.jj` when `--no-ignore` is used.
+* [BUG #3320](https://github.com/BurntSushi/ripgrep/pull/3419),

+  Fix gitignore matching bug when searching across multiple directories.
+
+
+15.1.0 (2025-10-22)
+===================
+This is a small release that fixes a bug with how ripgrep handles line
+buffering. This might manifest as ripgrep printing output later than you
+expect or not working correctly with `tail -f` (even if you're using the
+`--line-buffered` flag).
+
+Bug fixes:
+
+* [BUG #3194](https://github.com/BurntSushi/ripgrep/issues/3194):
+  Fix a regression with `--line-buffered` introduced in ripgrep 15.0.0.
+
+Feature enhancements:
+
+* [FEATURE #3192](https://github.com/BurntSushi/ripgrep/pull/3192):
+  Add hyperlink alias for Cursor.
+
+
+15.0.0 (2025-10-15)
+===================
+ripgrep 15 is a new major version release of ripgrep that mostly has bug fixes,
+some minor performance improvements and minor new features. Here are some
+highlights:
+
+* Several bugs around gitignore matching have been fixed. This includes
+  a commonly reported bug related to applying gitignore rules from parent
+  directories.
+* A memory usage regression when handling very large gitignore files has been
+  fixed.
+* `rg -vf file`, where `file` is empty, now matches everything.
+* The `-r/--replace` flag now works with `--json`.
+* A subset of Jujutsu (`jj`) repositories are now treated as if they were git
+  repositories. That is, ripgrep will respect `jj`'s gitignores.
+* Globs can now use nested curly braces.
+
+Platform support:
+
+* `aarch64` for Windows now has release artifacts.
+* `powerpc64` no longer has release artifacts generated for it. The CI
+  release workflow stopped working, and I didn't deem it worth my time to
+  debug it. If someone wants this and can test it, I'd be happy to add it
+  back.
+* ripgrep binaries are now compiled with full LTO enabled. You may notice
+  small performance improvements from this and a modest decrease in binary
+  size.
+
+Performance improvements:
+
+* [PERF #2111](https://github.com/BurntSushi/ripgrep/issues/2111):
+  Don't resolve helper binaries on Windows when `-z/--search-zip` isn't used.

+
+
+14.1.1 (2024-09-08)
+===================
+This is a minor release with a bug fix for a matching bug. In particular, a bug
+was found that could cause ripgrep to ignore lines that should match. That is,
+false negatives. It is difficult to characterize the specific set of regexes
+in which this occurs as it requires multiple different optimization strategies
+to collide and produce an incorrect result. But as one reported example, in
+ripgrep, the regex `(?i:e.x|ex)` does not match `e-x` when it should. (This
+bug is a result of an inner literal optimization performed in the `grep-regex`
+crate and not in the `regex` crate.)
+
+Bug fixes:
+
+* [BUG #2884](https://github.com/BurntSushi/ripgrep/issues/2884):
+  Fix bug where ripgrep could miss some matches that it should report.
+
+Miscellaneous:
+
+* [MISC #2748](https://github.com/BurntSushi/ripgrep/issues/2748):
+  Remove ripgrep's `simd-accel` feature because it was frequently broken.
+
+
+14.1.0 (2024-01-06)
+===================
+This is a minor release with a few small new features and bug fixes. This
+release contains a bug fix for unbounded memory growth while walking a
+directory tree. This release also includes improvements to the completions for
+the `fish` shell, and release binaries for several additional ARM targets.
+
+Bug fixes:
+
+* [BUG #2664](https://github.com/BurntSushi/ripgrep/issues/2690):
+  Fix unbounded memory growth in the `ignore` crate.
+
+Feature enhancements:
+
+* Added or improved file type filtering for Lean and Meson.
+* [FEATURE #2684](https://github.com/BurntSushi/ripgrep/issues/2684):
+  Improve completions for the `fish` shell.
+* [FEATURE #2702](https://github.com/BurntSushi/ripgrep/pull/2702):
+  Add release binaries for `armv7-unknown-linux-gnueabihf`,
+  `armv7-unknown-linux-musleabihf` and `armv7-unknown-linux-musleabi`.
+
+
+14.0.3 (2023-11-28)
+===================
+This is a patch release with a bug fix for the `--sortr` flag.
+
+Bug fixes:
+
+* [BUG #2664](https://github.com/BurntSushi/ripgrep/issues/2664):
+  Fix `--sortr=path`. I left a `todo!()` in the source. Oof.
+
+
+14.0.2 (2023-11-27)
+===================
+This is a patch release with a few small bug fixes.
+
+Bug fixes:
+
+* [BUG #2654](https://github.com/BurntSushi/ripgrep/issues/2654):
+  Fix `deb` release sha256 sum file.
+* [BUG #2658](https://github.com/BurntSushi/ripgrep/issues/2658):
+  Fix partial regression in the behavior of `--null-data --line-regexp`.
+* [BUG #2659](https://github.com/BurntSushi/ripgrep/issues/2659):
+  Fix Fish shell completions.
+* [BUG #2662](https://github.com/BurntSushi/ripgrep/issues/2662):
+  Fix typo in documentation for `-i/--ignore-case`.
+
+
+14.0.1 (2023-11-26)
+===================
+This a patch release meant to fix `cargo install ripgrep` on Windows.
+
+Bug fixes:
+
+* [BUG #2653](https://github.com/BurntSushi/ripgrep/issues/2653):
+  Include `pkg/windows/Manifest.xml` in crate package.
+
+
+14.0.0 (2023-11-26)
+===================
+ripgrep 14 is a new major version release of ripgrep that has some new
+features, performance improvements and a lot of bug fixes.
+
+The headlining feature in this release is hyperlink support. In this release,
+they are an opt-in feature but may change to an opt-out feature in the future.
+To enable them, try passing `--hyperlink-format default`. If you use [VS Code],
+then try passing `--hyperlink-format vscode`. Please [report your experience
+with hyperlinks][report-hyperlinks], positive or negative.
+
+[VS Code]: https://code.visualstudio.com/
+[report-hyperlinks]: https://github.com/BurntSushi/ripgrep/discussions/2611
+
+Another headlining development in this release is that it contains a rewrite
+of its regex engine. You generally shouldn't notice any changes, except for
+some searches may get faster. You can read more about the [regex engine rewrite
+on my blog][regex-internals]. Please [report your performance improvements or
+regressions that you notice][report-perf].
+
+[report-perf]: https://github.com/BurntSushi/ripgrep/discussions/2652
+
+Finally, ripgrep switched the library it uses for argument parsing. Users
+should not notice a difference in most cases (error messages have changed
+somewhat), but flag overrides should generally be more consistent. For example,
+things like `--no-ignore --ignore-vcs` work as one would expect (disables all
+filtering related to ignore rules except for rules found in version control
+systems such as `git`).
+
+[regex-internals]: https://blog.burntsushi.net/regex-internals/
+
+**BREAKING CHANGES**:
+
+* `rg -C1 -A2` used to be equivalent to `rg -A2`, but now it is equivalent to
+  `rg -B1 -A2`. That is, `-A` and `-B` no longer completely override `-C`.
+  Instead, they only partially override `-C`.
+
+Build process changes:
+
+* ripgrep's shell completions and man page are now created by running ripgrep
+with a new `--generate` flag. For example, `rg --generate man` will write a
+man page in `roff` format on stdout. The release archives have not changed.
+* The optional build dependency on `asciidoc` or `asciidoctor` has been
+dropped. Previously, it was used to produce ripgrep's man page. ripgrep now
+owns this process itself by writing `roff` directly.
+
+Performance improvements:
+
+* [PERF #1746](https://github.com/BurntSushi/ripgrep/issues/1746):
+  Make some cases with inner literals faster.
+* [PERF #1760](https://github.com/BurntSushi/ripgrep/issues/1760):

+* [PERF #2642](https://github.com/BurntSushi/ripgrep/pull/2642):
+  Parallel directory traversal has some contention reduced.

+bug fixes, some performance improvements and a few minor breaking changes.
+There is also a fix for a security vulnerability on Windows
+([CVE-2021-3013](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3013)).
+
+Some highlights:
+
+A new short flag, `-.`, has been added. It is an alias for the `--hidden` flag,
+which instructs ripgrep to search hidden files and directories.
+
+ripgrep is now using a new
+[vectorized implementation of `memmem`](https://github.com/BurntSushi/memchr/pull/82),
+which accelerates many common searches. If you notice any performance
+regressions (or major improvements), I'd love to hear about them through an
+issue report!
+
+Also, for Windows users targeting MSVC, Cargo will now build fully static
+executables of ripgrep. The release binaries for ripgrep 13 have been compiled
+using this configuration.
+
+**BREAKING CHANGES**:
+
+**Binary detection output has changed slightly.**
+
+In this release, a small tweak has been made to the output format when a binary
+file is detected. Previously, it looked like this:
+
+```
+Binary file FOO matches (found "\0" byte around offset XXX)
+```
+
+Now it looks like this:
+
+```
+FOO: binary file matches (found "\0" byte around offset XXX)
+```
+
+**vimgrep output in multi-line now only prints the first line for each match.**
+
+See [issue 1866](https://github.com/BurntSushi/ripgrep/issues/1866) for more
+discussion on this. Previously, every line in a match was duplicated, even
+when it spanned multiple lines. There are no changes to vimgrep output when
+multi-line mode is disabled.
+
+**In multi-line mode, --count is now equivalent to --count-matches.**
+
+This appears to match how `pcre2grep` implements `--count`. Previously, ripgrep
+would produce outright incorrect counts. Another alternative would be to simply
+count the number of lines---even if it's more than the number of matches---but
+that seems highly unintuitive.

+
+12.1.1 (2020-05-29)
+===================
+ripgrep 12.1.1 is a patch release that fixes a couple small bugs. In
+particular, the ripgrep 12.1.0 release did not tag new releases for all of its
+in-tree dependencies. As a result, ripgrep built dependencies from crates.io
+would produce a different build than compiling ripgrep from source on the
+`12.1.0` tag. Namely, some crates like `grep-cli` had unreleased changes.
+
+Bug fixes:
+
+* [BUG #1581](https://github.com/BurntSushi/ripgrep/issues/1581):
+  Corrects some egregious markup output in `--help`.
+* [BUG #1591](https://github.com/BurntSushi/ripgrep/issues/1591):
+  Mention the special `$0` capture group in docs for the `-r/--replace` flag.
+* [BUG #1602](https://github.com/BurntSushi/ripgrep/issues/1602):
+  Fix failing test resulting from out-of-sync dependencies.
+
+
+12.1.0 (2020-05-09)
+===================
+ripgrep 12.1.0 is a small minor version release that mostly includes bug fixes
+and documentation improvements. This release also contains some important
+notices for downstream packagers.
+
+**Notices for downstream ripgrep package maintainers:**
+
+* Fish shell completions will be removed in the ripgrep 13 release.
+  See [#1577](https://github.com/BurntSushi/ripgrep/issues/1577)
+  for more details.
+* ripgrep has switched from `a2x` to `asciidoctor` to generate the man page.
+  If `asciidoctor` is not present, then ripgrep will currently fall back to
+  `a2x`. Support for `a2x` will be dropped in the ripgrep 13 release.
+  See [#1544](https://github.com/BurntSushi/ripgrep/issues/1544)
+  for more details.
+
+Feature enhancements:
+
+* [FEATURE #1547](https://github.com/BurntSushi/ripgrep/pull/1547):
+  Support decompressing `.Z` files via `uncompress`.
+
+Bug fixes:
+
+* [BUG #1252](https://github.com/BurntSushi/ripgrep/issues/1252):

+  Substantially reduce peak memory usage when searching wide directories.
+* [BUG #1571](https://github.com/BurntSushi/ripgrep/issues/1571):
+  Add note about configuration files in `--type-{add,clear}` docs.
+* [BUG #1573](https://github.com/BurntSushi/ripgrep/issues/1573):
+  Fix incorrect `--count-matches` output when using look-around.
+
+
+12.0.1 (2020-03-29)
+===================
+ripgrep 12.0.1 is a small patch release that includes a minor bug fix relating
+to superfluous error messages when searching git repositories with sub-modules.
+This was a regression introduced in the 12.0.0 release.
+
+Bug fixes:
+
+* [BUG #1520](https://github.com/BurntSushi/ripgrep/issues/1520):
+  Don't emit spurious error messages in git repositories with submodules.
+
+
+12.0.0 (2020-03-15)
+===================
+ripgrep 12 is a new major version release of ripgrep that contains many bug
+fixes, several important performance improvements and a few minor new features.
+
+In a near future release, I am hoping to add an
+[indexing feature](https://github.com/BurntSushi/ripgrep/issues/1497)
+to ripgrep, which will dramatically speed up searching by building an index.
+Feedback would very much be appreciated, especially on the user experience
+which will be difficult to get right.
+
+This release has no known breaking changes.
+
+Deprecations:
+
+* The `--no-pcre2-unicode` flag is deprecated. Instead, use the `--no-unicode`
+  flag, which applies to both the default regex engine and PCRE2. For now,
+  `--no-pcre2-unicode` and `--pcre2-unicode` are aliases to `--no-unicode`
+  and `--unicode`, respectively. The `--[no-]pcre2-unicode` flags may be
+  removed in a future release.
+* The `--auto-hybrid-regex` flag is deprecated. Instead, use the new `--engine`
+  flag with the `auto` value.
+
+Performance improvements:
+
+* [PERF #1087](https://github.com/BurntSushi/ripgrep/pull/1087):
+  ripgrep is smarter when detected literals are whitespace.
+* [PERF #1381](https://github.com/BurntSushi/ripgrep/pull/1381):
+  Directory traversal is sped up with speculative ignore-file existence checks.
+* [PERF cd8ec38a](https://github.com/BurntSushi/ripgrep/commit/cd8ec38a):
+  Improve inner literal detection to cover more cases more effectively.
+  e.g., ` +Sherlock Holmes +` now has ` Sherlock Holmes ` extracted instead
+  of ` `.
+* [PERF 6a0e0147](https://github.com/BurntSushi/ripgrep/commit/6a0e0147):
+  Improve literal detection when the `-w/--word-regexp` flag is used.
+* [PERF ad97e9c9](https://github.com/BurntSushi/ripgrep/commit/ad97e9c9):
+  Improve overall performance of the `-w/--word-regexp` flag.

+
+11.0.1 (2019-04-16)
+===================
+ripgrep 11.0.1 is a new patch release that fixes a search regression introduced
+in the previous 11.0.0 release. In particular, ripgrep can enter an infinite
+loop for some search patterns when searching invalid UTF-8.
+
+Bug fixes:
+
+* [BUG #1247](https://github.com/BurntSushi/ripgrep/issues/1247):
+  Fix search bug that can cause ripgrep to enter an infinite loop.
+
+
+11.0.0 (2019-04-15)
+===================
+ripgrep 11 is a new major version release of ripgrep that contains many bug
+fixes, some performance improvements and a few feature enhancements. Notably,
+ripgrep's user experience for binary file filtering has been improved. See the
+[guide's new section on binary data](GUIDE.md#binary-data) for more details.
+
+This release also marks a change in ripgrep's versioning. Where as the previous
+version was `0.10.0`, this version is `11.0.0`. Moving forward, ripgrep's
+major version will be increased a few times per year. ripgrep will continue to
+be conservative with respect to backwards compatibility, but may occasionally
+introduce breaking changes, which will always be documented in this CHANGELOG.
+See [issue 1172](https://github.com/BurntSushi/ripgrep/issues/1172) for a bit
+more detail on why this versioning change was made.
+
+This release increases the **minimum supported Rust version** from 1.28.0 to
+1.34.0.
+
+**BREAKING CHANGES**:
+
+* ripgrep has tweaked its exit status codes to be more like GNU grep's. Namely,
+  if a non-fatal error occurs during a search, then ripgrep will now always
+  emit a `2` exit status code, regardless of whether a match is found or not.
+  Previously, ripgrep would only emit a `2` exit status code for a catastrophic
+  error (e.g., regex syntax error). One exception to this is if ripgrep is run
+  with `-q/--quiet`. In that case, if an error occurs and a match is found,
+  then ripgrep will exit with a `0` exit status code.
+* Supplying the `-u/--unrestricted` flag three times is now equivalent to
+  supplying `--no-ignore --hidden --binary`. Previously, `-uuu` was equivalent
+  to `--no-ignore --hidden --text`. The difference is that `--binary` disables
+  binary file filtering without potentially dumping binary data into your
+  terminal. That is, `rg -uuu foo` should now be equivalent to `grep -r foo`.
+* The `avx-accel` feature of ripgrep has been removed since it is no longer
+  necessary. All uses of AVX in ripgrep are now enabled automatically via
+  runtime CPU feature detection. The `simd-accel` feature does remain available
+  (only for enabling SIMD for transcoding), however, it does increase
+  compilation times substantially at the moment.
+
+Performance improvements:
+
+* [PERF #497](https://github.com/BurntSushi/ripgrep/issues/497),
+  [PERF #838](https://github.com/BurntSushi/ripgrep/issues/838):
+  Make `rg -F -f dictionary-of-literals` much faster.
+
+Feature enhancements:
+
+* Added or improved file type filtering for Apache Thrift, ASP, Bazel, Brotli,
+  BuildStream, bzip2, C, C++, Cython, gzip, Java, Make, Postscript, QML, Tex,
+  XML, xz, zig and zstd.
+* [FEATURE #855](https://github.com/BurntSushi/ripgrep/issues/855):
+  Add `--binary` flag for disabling binary file filtering.
+* [FEATURE #1078](https://github.com/BurntSushi/ripgrep/pull/1078):
+  Add `--max-columns-preview` flag for showing a preview of long lines.
+* [FEATURE #1099](https://github.com/BurntSushi/ripgrep/pull/1099):
+  Add support for Brotli and Zstd to the `-z/--search-zip` flag.
+* [FEATURE #1138](https://github.com/BurntSushi/ripgrep/pull/1138):
+  Add `--no-ignore-dot` flag for ignoring `.ignore` files.
+* [FEATURE #1155](https://github.com/BurntSushi/ripgrep/pull/1155):
+  Add `--auto-hybrid-regex` flag for automatically falling back to PCRE2.
+* [FEATURE #1159](https://github.com/BurntSushi/ripgrep/pull/1159):
+  ripgrep's exit status logic should now match GNU grep. See updated man page.
+* [FEATURE #1164](https://github.com/BurntSushi/ripgrep/pull/1164):
+  Add `--ignore-file-case-insensitive` for case insensitive ignore globs.
+* [FEATURE #1185](https://github.com/BurntSushi/ripgrep/pull/1185):
+  Add `-I` flag as a short option for the `--no-filename` flag.
+* [FEATURE #1207](https://github.com/BurntSushi/ripgrep/pull/1207):
+  Add `none` value to `-E/--encoding` to forcefully disable all transcoding.
+* [FEATURE da9d7204](https://github.com/BurntSushi/ripgrep/commit/da9d7204):
+  Add `--pcre2-version` for querying showing PCRE2 version information.
+
+Bug fixes:
+
+* [BUG #306](https://github.com/BurntSushi/ripgrep/issues/306),
+  [BUG #855](https://github.com/BurntSushi/ripgrep/issues/855):
+  Improve the user experience for ripgrep's binary file filtering.
+* [BUG #373](https://github.com/BurntSushi/ripgrep/issues/373),
+  [BUG #1098](https://github.com/BurntSushi/ripgrep/issues/1098):

+  Fixes a bug where the order of globs could result in missing a match.
+* [BUG #1089](https://github.com/BurntSushi/ripgrep/issues/1089):
+  Fix another bug where ripgrep could panic when transcoding UTF-16 files.

+
+0.10.0 (2018-09-07)
+===================
+This is a new minor version release of ripgrep that contains some major new
+features, a huge number of bug fixes, and is the first release based on
+libripgrep. The entirety of ripgrep's core search and printing code has been
+rewritten and generalized so that anyone can make use of it.
+
+Major new features include PCRE2 support, multi-line search and a JSON output
+format.
+
+**BREAKING CHANGES**:
+
+* The minimum version required to compile Rust has now changed to track the
+  latest stable version of Rust. Patch releases will continue to compile with
+  the same version of Rust as the previous patch release, but new minor
+  versions will use the current stable version of the Rust compile as its
+  minimum supported version.
+* The match semantics of `-w/--word-regexp` have changed slightly. They used
+  to be `\b(?:)\b`, but now it's
+  `(?:^|\W)(?:)(?:$|\W)`. This matches the behavior of GNU grep
+  and is believed to be closer to the intended semantics of the flag. See
+  [#389](https://github.com/BurntSushi/ripgrep/issues/389) for more details.
+
+Feature enhancements:

+
+
+0.9.0 (2018-08-03)
+==================
+This is a new minor version release of ripgrep that contains some minor new
+features and a panoply of bug fixes.
+
+Releases provided on Github for `x86_64` will now work on all target CPUs, and
+will also automatically take advantage of features found on modern CPUs (such
+as AVX2) for additional optimizations.
+
+This release increases the **minimum supported Rust version** from 1.20.0 to
+1.23.0.
+
+It is anticipated that the next release of ripgrep (0.10.0) will provide
+multi-line search support and a JSON output format.
+
+**BREAKING CHANGES**:
+
+* When `--count` and `--only-matching` are provided simultaneously, the
+  behavior of ripgrep is as if the `--count-matches` flag was given. That is,
+  the total number of matches is reported, where there may be multiple matches
+  per line. Previously, the behavior of ripgrep was to report the total number
+  of matching lines. (Note that this behavior diverges from the behavior of
+  GNU grep.)
+* Octal syntax is no longer supported. ripgrep previously accepted expressions
+  like `\1` as syntax for matching `U+0001`, but ripgrep will now report an
+  error instead.
+* The `--line-number-width` flag has been removed. Its functionality was not
+  carefully considered with all ripgrep output formats.
+  See [#795](https://github.com/BurntSushi/ripgrep/issues/795) for more
+  details.
+
+Feature enhancements:
+
+* Added or improved file type filtering for Android, Bazel, Fuchsia, Haskell,
+  Java and Puppet.
+* [FEATURE #411](https://github.com/BurntSushi/ripgrep/issues/411):
+  Add a `--stats` flag, which emits aggregate statistics after search results.
+* [FEATURE #646](https://github.com/BurntSushi/ripgrep/issues/646):
+  Add a `--no-ignore-messages` flag, which suppresses parse errors from reading
+  `.ignore` and `.gitignore` files.
+* [FEATURE #702](https://github.com/BurntSushi/ripgrep/issues/702):
+  Support `\u{..}` Unicode escape sequences.
+* [FEATURE #812](https://github.com/BurntSushi/ripgrep/issues/812):
+  Add `-b/--byte-offset` flag that shows the byte offset of each matching line.
+* [FEATURE #814](https://github.com/BurntSushi/ripgrep/issues/814):
+  Add `--count-matches` flag, which is like `--count`, but for each match.

+  Add a new flag, `--no-ignore-global`, that permits disabling global
+  gitignores.
+* [FEATURE #967](https://github.com/BurntSushi/ripgrep/issues/967):
+  Rename `--maxdepth` to `--max-depth` for consistency. Keep `--maxdepth` for
+  backwards compatibility.
+* [FEATURE #978](https://github.com/BurntSushi/ripgrep/issues/978):
+  Add a `--pre` option to filter inputs with an arbitrary program.
+* [FEATURE fca9709d](https://github.com/BurntSushi/ripgrep/commit/fca9709d):
+  Improve zsh completion.
+
+Bug fixes:
+
+* [BUG #135](https://github.com/BurntSushi/ripgrep/issues/135):
+  Release portable binaries that conditionally use SSSE3, AVX2, etc., at
+  runtime.
+* [BUG #268](https://github.com/BurntSushi/ripgrep/issues/268):
+  Print descriptive error message when trying to use look-around or
+  backreferences.

+  Improve support for git submodules.
+* [BUG #900](https://github.com/BurntSushi/ripgrep/issues/900):
+  When no patterns are given, ripgrep should never match anything.
+* [BUG #907](https://github.com/BurntSushi/ripgrep/issues/907):

+
+
+0.8.0 (2018-02-11)
+==================
+This is a new minor version release of ripgrep that satisfies several popular
+feature requests (config files, search compressed files, true colors), fixes
+many bugs and improves the quality of life for ripgrep maintainers. This
+release also includes greatly improved documentation in the form of a
+[User Guide](GUIDE.md) and a [FAQ](FAQ.md).
+
+This release increases the **minimum supported Rust version** from 1.17 to
+1.20.
+
+**BREAKING CHANGES**:
+
+Note that these are all very minor and unlikely to impact most users.
+
+* In order to support configuration files, flag overrides needed to be
+  rethought. In some cases, this changed ripgrep's behavior. For example,
+  in ripgrep 0.7.1, `rg foo -s -i` will perform a case sensitive search
+  since the `-s/--case-sensitive` flag was defined to always take precedence
+  over the `-i/--ignore-case` flag, regardless of position. In ripgrep 0.8.0
+  however, the override rule for all flags has changed to "the most recent
+  flag wins among competing flags." That is, `rg foo -s -i` now performs a
+  case insensitive search.
+* The `-M/--max-columns` flag was tweaked so that specifying a value of `0`
+  now makes ripgrep behave as if the flag was absent. This makes it possible
+  to set a default value in a configuration file and then override it. The
+  previous ripgrep behavior was to suppress all matching non-empty lines.
+* In all globs, `[^...]` is now equivalent to `[!...]` (indicating class
+  negation). Previously, `^` had no special significance in a character class.
+* For **downstream packagers**, the directory hierarchy in ripgrep's archive
+  releases has changed. The root directory now only contains the executable,
+  README and license. There is now a new directory called `doc` which contains
+  the man page (previously in the root), a user guide (new), a FAQ (new) and
+  the CHANGELOG (previously not included in release). The `complete`
+  directory remains the same.
+
+Feature enhancements:
+
+* Added or improved file type filtering for
+  Apache Avro, C++, GN, Google Closure Templates, Jupyter notebooks, man pages,
+  Protocol Buffers, Smarty and Web IDL.
+* [FEATURE #196](https://github.com/BurntSushi/ripgrep/issues/196):
+  Support a configuration file. See
+  [the new user guide](GUIDE.md#configuration-file)
+  for details.
+* [FEATURE #261](https://github.com/BurntSushi/ripgrep/issues/261):
+  Add extended or "true" color support. Works in Windows 10!
+  [See the FAQ for details.](FAQ.md#colors)
+* [FEATURE #539](https://github.com/BurntSushi/ripgrep/issues/539):
+  Search gzip, bzip2, lzma or xz files when given `-z/--search-zip` flag.
+* [FEATURE #544](https://github.com/BurntSushi/ripgrep/issues/544):
+  Add support for line number alignment via a new `--line-number-width` flag.
+* [FEATURE #654](https://github.com/BurntSushi/ripgrep/pull/654):
+  Support linuxbrew in ripgrep's Brew tap.
+* [FEATURE #673](https://github.com/BurntSushi/ripgrep/issues/673):
+  Bring back `.rgignore` files. (A higher precedent, application specific
+  version of `.ignore`.)
+* [FEATURE #676](https://github.com/BurntSushi/ripgrep/issues/676):
+  Provide ARM binaries. **WARNING:** This will be provided on a best effort
+  basis.
+* [FEATURE #709](https://github.com/BurntSushi/ripgrep/issues/709):
+  Suggest `-F/--fixed-strings` flag on a regex syntax error.
+* [FEATURE #740](https://github.com/BurntSushi/ripgrep/issues/740):
+  Add a `--passthru` flag that causes ripgrep to print every line it reads.
+* [FEATURE #785](https://github.com/BurntSushi/ripgrep/pull/785):
+  Overhaul documentation. Cleaned up README, added user guide and FAQ.
+* [FEATURE 7f5c07](https://github.com/BurntSushi/ripgrep/commit/7f5c07434be92103b5bf7e216b9c7494aed2d8cb):
+  Add hidden flags for convenient overrides (e.g., `--no-text`).

+  Remove `yarn.lock` from YAML file type.
+* [BUG #760](https://github.com/BurntSushi/ripgrep/issues/760):

+==================
+This is a new minor version release of ripgrep that includes one minor breaking
+change, bug fixes and several new features including support for text encodings
+other than UTF-8.
+
+A notable accomplishment with respect to Rust is that ripgrep proper now only
+contains a single `unsafe` use (for accessing the contents of a memory map).
+
+The **breaking change** is:
+
+* [FEATURE #380](https://github.com/BurntSushi/ripgrep/issues/380):
+  Line numbers are now hidden by default when ripgrep is printing to a tty
+  **and** the only thing searched is stdin.

+  SASS, SVG, Twig
+* [FEATURE #1](https://github.com/BurntSushi/ripgrep/issues/1):

+  UTF-16 via BOM sniffing. Explicit text encoding support with the
+  `-E/--encoding` flag was also added for latin-1, GBK, EUC-JP
+  and Shift_JIS, among others. The full list can be found here:
+  https://encoding.spec.whatwg.org/#concept-encoding-get
+* [FEATURE #129](https://github.com/BurntSushi/ripgrep/issues/129):
+  Add a new `-M/--max-columns` flag that omits lines longer than the given
+  number of bytes. (Disabled by default!)
+* [FEATURE #369](https://github.com/BurntSushi/ripgrep/issues/369):
+  A new flag, `--max-filesize`, was added for limiting searches to files with
+  a maximum file size.
+
+Bug fixes:
+
+* [BUG #52](https://github.com/BurntSushi/ripgrep/issues/52),
+  [BUG #311](https://github.com/BurntSushi/ripgrep/issues/311):
+  Tweak how binary files are detected and handled. (We are slightly less
+  conservative and will no longer use memory without bound.)
+* [BUG #326](https://github.com/BurntSushi/ripgrep/issues/326):
+  When --files flag is given, we should never attempt to parse positional
+  arguments as regexes.
+* [BUG #327](https://github.com/BurntSushi/ripgrep/issues/327):
+  Permit the --heading flag to override the --no-heading flag.
+* [BUG #340](https://github.com/BurntSushi/ripgrep/pull/340):
+  Clarify that the `-u/--unrestricted` flags are aliases.
+* [BUG #343](https://github.com/BurntSushi/ripgrep/pull/343):

+  Clarify docs for `-g/--glob` flag.
+* [BUG #381](https://github.com/BurntSushi/ripgrep/issues/381):
+  Add license files to each sub-crate.
+* [BUG #383](https://github.com/BurntSushi/ripgrep/issues/383):
+  Use latest version of clap (for argv parsing).
+* [BUG #392](https://github.com/BurntSushi/ripgrep/issues/391):
+  Fix translation of set globs (e.g., `{foo,bar,quux}`) to regexes.
+* [BUG #401](https://github.com/BurntSushi/ripgrep/pull/401):
+  Add PowerShell completion file to Windows release.
+* [BUG #405](https://github.com/BurntSushi/ripgrep/issues/405):
+  Fix bug when excluding absolute paths with the `-g/--glob` flag.
+
+
+0.4.0
+=====
+This is a new minor version release of ripgrep that includes a couple very
+minor breaking changes, a few new features and lots of bug fixes.
+
+This version of ripgrep upgrades its `regex` dependency from `0.1` to `0.2`,
+which includes a few minor syntax changes:
+
+* POSIX character classes now require double bracketing. Previously, the regex
+  `[:upper:]` would parse as the `upper` POSIX character class. Now it parses
+  as the character class containing the characters `:upper:`. The fix to this
+  change is to use `[[:upper:]]` instead. Note that variants like
+  `[[:upper:][:blank:]]` continue to work.
+* The character `[` must always be escaped inside a character class.
+* The characters `&`, `-` and `~` must be escaped if any one of them are
+  repeated consecutively. For example, `[&]`, `[\&]`, `[\&\&]`, `[&-&]` are all
+  equivalent while `[&&]` is illegal. (The motivation for this and the prior
+  change is to provide a backwards compatible path for adding character class
+  set notation.)
+
+Feature enhancements:
+
+* Added or improved file type filtering for Crystal, Kotlin, Perl, PowerShell,
+  Ruby, Swig
+* [FEATURE #83](https://github.com/BurntSushi/ripgrep/issues/83):
+  Type definitions can now include other type definitions.
+* [FEATURE #243](https://github.com/BurntSushi/ripgrep/issues/243):
+  **BREAKING CHANGE**: The `--column` flag now implies `--line-number`.
+* [FEATURE #263](https://github.com/BurntSushi/ripgrep/issues/263):
+  Add a new `--sort-files` flag.
+* [FEATURE #275](https://github.com/BurntSushi/ripgrep/issues/275):
+  Add a new `--path-separator` flag. Useful in cygwin.
+
+Bug fixes:
+
+* [BUG #182](https://github.com/BurntSushi/ripgrep/issues/182):
+  Redux: use more portable ANSI color escape sequences when possible.
+* [BUG #258](https://github.com/BurntSushi/ripgrep/issues/258):

+  **BREAKING CHANGE**: Completely remove `^C` handling from ripgrep.
+* [BUG #284](https://github.com/BurntSushi/ripgrep/issues/284):
+  Make docs for `-g/--glob` clearer.
+* [BUG #286](https://github.com/BurntSushi/ripgrep/pull/286):
+  When stdout is redirected to a file, don't search that file.
+* [BUG #287](https://github.com/BurntSushi/ripgrep/pull/287):
+  Fix ZSH completions.
+* [BUG #295](https://github.com/BurntSushi/ripgrep/pull/295):

+* [BUG #256](https://github.com/BurntSushi/ripgrep/issues/256):
+  Fix bug that caused `rg foo` and `rg foo/` to have different behavior
+  when `foo` was a symlink.
+* [BUG #270](https://github.com/BurntSushi/ripgrep/issues/270):
+  Fix bug where patterns starting with a `-` couldn't be used with the
+  `-e/--regexp` flag. (This resolves a regression that was introduced in
+  ripgrep 0.3.0.)
+
+
+0.3.1
+=====
+Bug fixes:
+
+* [BUG #242](https://github.com/BurntSushi/ripgrep/issues/242):
+  ripgrep didn't respect `--colors foo:none` correctly. Now it does.
+
+
+0.3.0
+=====
+This is a new minor version release of ripgrep that includes two breaking
+changes with lots of bug fixes and some new features and performance
+improvements. Notably, if you had a problem with colors or piping on Windows
+before, then that should now be fixed in this release.
+
+**BREAKING CHANGES**:
+
+* ripgrep now requires Rust 1.11 to compile. Previously, it could build on
+  Rust 1.9. The cause of this was the move from
+  [Docopt to Clap](https://github.com/BurntSushi/ripgrep/pull/233)
+  for argument parsing.
+* The `-e/--regexp` flag can no longer accept a pattern starting with a `-`.
+  There are two work-arounds: `rg -- -foo` and `rg [-]foo` or `rg -e [-]foo`
+  will all search for the same `-foo` pattern. The cause of this was the move
+  from [Docopt to Clap](https://github.com/BurntSushi/ripgrep/pull/233)
+  for argument parsing.
+  [This may get fixed in the
+  future.](https://github.com/kbknapp/clap-rs/issues/742).
+
+Performance improvements:
+
+* [PERF #33](https://github.com/BurntSushi/ripgrep/issues/33):
+  ripgrep now performs similar to GNU grep on small corpora.
+* [PERF #136](https://github.com/BurntSushi/ripgrep/issues/136):
+  ripgrep no longer slows down because of argument parsing when given a large
+  argument list.
+
+Feature enhancements:
+
+* Added or improved file type filtering for Elixir.
+* [FEATURE #7](https://github.com/BurntSushi/ripgrep/issues/7):
+  Add a `-f/--file` flag that causes ripgrep to read patterns from a file.
+* [FEATURE #51](https://github.com/BurntSushi/ripgrep/issues/51):
+  Add a `--colors` flag that enables one to customize the colors used in
+  ripgrep's output.
+* [FEATURE #138](https://github.com/BurntSushi/ripgrep/issues/138):
+  Add a `--files-without-match` flag that shows only file paths that contain
+  zero matches.
+* [FEATURE #230](https://github.com/BurntSushi/ripgrep/issues/230):
+  Add completion files to the release (Bash, Fish and PowerShell).
+
+Bug fixes:
+
+* [BUG #37](https://github.com/BurntSushi/ripgrep/issues/37):
+  Use correct ANSI escape sequences when `TERM=screen.linux`.
+* [BUG #94](https://github.com/BurntSushi/ripgrep/issues/94):
+  ripgrep now detects stdin on Windows automatically.
+* [BUG #117](https://github.com/BurntSushi/ripgrep/issues/117):
+  Colors should now work correctly and automatically inside mintty.
+* [BUG #182](https://github.com/BurntSushi/ripgrep/issues/182):
+  Colors should now work within Emacs. In particular, `--color=always` will
+  emit colors regardless of the current environment.
+* [BUG #189](https://github.com/BurntSushi/ripgrep/issues/189):
+  Show less content when running `rg -h`. The full help content can be
+  accessed with `rg --help`.
+* [BUG #210](https://github.com/BurntSushi/ripgrep/issues/210):
+  Support non-UTF-8 file names on Unix platforms.
+* [BUG #231](https://github.com/BurntSushi/ripgrep/issues/231):
+  Switch from block buffering to line buffering.
+* [BUG #241](https://github.com/BurntSushi/ripgrep/issues/241):
+  Some error messages weren't suppressed when `--no-messages` was used.
+
+
+0.2.9
+=====
+Bug fixes:
+
+* [BUG #226](https://github.com/BurntSushi/ripgrep/issues/226):
+  File paths explicitly given on the command line weren't searched in parallel.
+  (This was a regression in `0.2.7`.)
+* [BUG #228](https://github.com/BurntSushi/ripgrep/issues/228):
+  If a directory was given to `--ignore-file`, ripgrep's memory usage would
+  grow without bound.
+
+
+0.2.8
+=====
+Bug fixes:
+
+* Fixed a bug with the SIMD/AVX features for using bytecount in commit
+  `4ca15a`.

+
+0.2.7
+=====
+Performance improvements:
+
+* [PERF #223](https://github.com/BurntSushi/ripgrep/pull/223):
+  Added a parallel recursive directory iterator. This results in major
+  performance improvements on large repositories.
+* [PERF #11](https://github.com/BurntSushi/ripgrep/pull/11):
+  ripgrep now uses the `bytecount` library for counting new lines. In some
+  cases, ripgrep runs twice as fast. Use
+  `RUSTFLAGS="-C target-cpu=native" cargo build --release --features 'simd-accel avx-accel'`
+  to get the fastest possible binary.
+
+Feature enhancements:
+
+* Added or improved file type filtering for Agda, Tex, Taskpaper, Markdown,
+  asciidoc, textile, rdoc, org, creole, wiki, pod, C#, PDF, C, C++.
+* [FEATURE #149](https://github.com/BurntSushi/ripgrep/issues/149):
+  Add a new `--no-messages` flag that suppresses error messages.
+  Note that `rg foo 2> /dev/null` also works.
+* [FEATURE #159](https://github.com/BurntSushi/ripgrep/issues/159):
+  Add a new `-m/--max-count` flag that limits the total number of matches
+  printed for each file searched.
+
+Bug fixes:
+
+* [BUG #199](https://github.com/BurntSushi/ripgrep/issues/199):
+  Fixed a bug where `-S/--smart-case` wasn't being applied correctly to
+  literal optimizations.
+* [BUG #203](https://github.com/BurntSushi/ripgrep/issues/203):
+  Mention the full name, ripgrep, in more places. It now appears in
+  the output of `--help` and `--version`. The repository URL is now also
+  in the output of `--help` and the man page.
+* [BUG #215](https://github.com/BurntSushi/ripgrep/issues/215):
+  Include small note about how to search for a pattern that starts with a `-`.

+
+0.2.1
+=====
+Feature enhancements:
+
+* Added or improved file type filtering for Clojure and SystemVerilog.
+* [FEATURE #89](https://github.com/BurntSushi/ripgrep/issues/89):
+  Add a --null flag that outputs a NUL byte after every file path.
+
+Bug fixes:
+
+* [BUG #98](https://github.com/BurntSushi/ripgrep/issues/98):
+  Fix a bug in single threaded mode when if opening a file failed, ripgrep
+  quit instead of continuing the search.
+* [BUG #99](https://github.com/BurntSushi/ripgrep/issues/99):
+  Fix another bug in single threaded mode where empty lines were being printed
+  by mistake.
+* [BUG #105](https://github.com/BurntSushi/ripgrep/issues/105):
+  Fix an off-by-one error with --column.
+* [BUG #106](https://github.com/BurntSushi/ripgrep/issues/106):
+  Fix a bug where a whitespace only line in a gitignore file caused ripgrep
+  to panic (i.e., crash).
+
+
+0.2.0
+=====
+Feature enhancements:
+
+* Added or improved file type filtering for VB, R, F#, Swift, Nim, JavaScript,
+  TypeScript
+* [FEATURE #20](https://github.com/BurntSushi/ripgrep/issues/20):
+  Adds a --no-filename flag.
+* [FEATURE #26](https://github.com/BurntSushi/ripgrep/issues/26):
+  Adds --files-with-matches flag. Like --count, but only prints file paths
+  and doesn't need to count every match.
+* [FEATURE #40](https://github.com/BurntSushi/ripgrep/issues/40):
+  Switch from using `.rgignore` to `.ignore`. Note that `.rgignore` is
+  still supported, but deprecated.
+* [FEATURE #68](https://github.com/BurntSushi/ripgrep/issues/68):
+  Add --no-ignore-vcs flag that ignores .gitignore but not .ignore.

+Many many bug fixes. Thanks every for reporting these and helping make
+`ripgrep` better! (Note that I haven't captured every tracking issue here,
+some were closed as duplicates.)
+
+* [BUG #8](https://github.com/BurntSushi/ripgrep/issues/8):
+  Don't use an intermediate buffer when --threads=1. (Permits constant memory
+  usage.)
+* [BUG #15](https://github.com/BurntSushi/ripgrep/issues/15):
+  Improves the documentation for --type-add.
+* [BUG #16](https://github.com/BurntSushi/ripgrep/issues/16),
+  [BUG #49](https://github.com/BurntSushi/ripgrep/issues/49),
+  [BUG #50](https://github.com/BurntSushi/ripgrep/issues/50),
+  [BUG #65](https://github.com/BurntSushi/ripgrep/issues/65):
+  Some gitignore globs were being treated as anchored when they weren't.
+* [BUG #18](https://github.com/BurntSushi/ripgrep/issues/18):
+  --vimgrep reported incorrect column number.
+* [BUG #19](https://github.com/BurntSushi/ripgrep/issues/19):
+  ripgrep was hanging waiting on stdin in some Windows terminals. Note that
+  this introduced a new bug:
+  [#94](https://github.com/BurntSushi/ripgrep/issues/94).
+* [BUG #21](https://github.com/BurntSushi/ripgrep/issues/21):

+  Anchored gitignore globs weren't applied in subdirectories correctly.
+* [BUG #30](https://github.com/BurntSushi/ripgrep/issues/30):
+  Globs like `foo/**` should match contents of `foo`, but not `foo` itself.
+* [BUG #35](https://github.com/BurntSushi/ripgrep/issues/35),
+  [BUG #81](https://github.com/BurntSushi/ripgrep/issues/81):
+  When automatically detecting stdin, only read if it's a file or a fifo.
+  i.e., ignore stdin in `rg foo < /dev/null`.
+* [BUG #36](https://github.com/BurntSushi/ripgrep/issues/36):
+  Don't automatically pick memory maps on MacOS. Ever.
+* [BUG #38](https://github.com/BurntSushi/ripgrep/issues/38):
+  Trailing whitespace in gitignore wasn't being ignored.
+* [BUG #43](https://github.com/BurntSushi/ripgrep/issues/43):
+  --glob didn't work with directories.
+* [BUG #46](https://github.com/BurntSushi/ripgrep/issues/46):
+  Use one fewer worker thread than what is provided on CLI.
+* [BUG #47](https://github.com/BurntSushi/ripgrep/issues/47):
+  --help/--version now work even if other options are set.
+* [BUG #55](https://github.com/BurntSushi/ripgrep/issues/55):
+  ripgrep was refusing to search /proc/cpuinfo. Fixed by disabling memory
+  maps for files with zero size.
+* [BUG #64](https://github.com/BurntSushi/ripgrep/issues/64):
+  The first path given with --files set was ignored.
+* [BUG #67](https://github.com/BurntSushi/ripgrep/issues/67):
+  Sometimes whitelist globs like `!/dir` weren't interpreted as anchored.
+* [BUG #77](https://github.com/BurntSushi/ripgrep/issues/77):
+  When -q/--quiet flag was passed, ripgrep kept searching even after a match
+  was found.
+* [BUG #90](https://github.com/BurntSushi/ripgrep/issues/90):
+  Permit whitelisting hidden files.
+* [BUG #93](https://github.com/BurntSushi/ripgrep/issues/93):
+  ripgrep was extracting an erroneous inner literal from a repeated pattern.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate 2D Perlin noise at the point inside cell (0,1) with local coordinates (0.77, 0.812). The four corner gradients are g00=(-1, 0), g10=(0, 1), g01=(0, -1), g11=(1, 1). Show the steps, and explain what the fade curve is for.<｜Assistant｜>Perlin noise is dot products of corner gradients with corner-to-point offsets, blended by a smooth curve.
+
+Offset vectors from each corner to the sample point:
+  d00 = (0.77, 0.812)   d10 = (-0.23, 0.812)
+  d01 = (0.77, -0.188)   d11 = (-0.23, -0.188)
+
+Corner contributions (gradient · offset):
+  n00 = (-1, 0)·(0.77,0.812) = -0.77
+  n10 = (0, 1)·(-0.23,0.812) = 0.812
+  n01 = (0, -1)·(0.77,-0.188) = 0.188
+  n11 = (1, 1)·(-0.23,-0.188) = -0.418
+
+Fade curve 6t⁵-15t⁴+10t³:
+  u = fade(0.77) = 0.916444
+  v = fade(0.812) = 0.950882
+
+Bilinear blend using the faded weights:
+  nx0 = lerp(n00, n10, u) = 0.679815
+  nx1 = lerp(n01, n11, u) = -0.367365
+  value = lerp(nx0, nx1, v) = -0.31593
+
+Why fade and not plain lerp: the noise value must be C² across cell boundaries or the derivative jumps and you see a visible grid. 6t⁵-15t⁴+10t³ has f(0)=0, f(1)=1 and *both* first and second derivatives zero at the ends, so gradients and curvature match across the seam. Perlin's original 1985 version used 3t²-2t³, which is only C¹ — that is why the 1985 noise shows faint grid artefacts under a normal map and the 2002 'improved' version does not.
+
+With a plain linear blend (u = 0.77) the value here would be -0.141989 instead of -0.31593 — a small difference at one sample, but discontinuous in slope at every cell edge across the whole field.noise(0+0.77, 1+0.812) = **-0.31593**
+
+Steps: corner dots n00=-0.77, n10=0.812, n01=0.188, n11=-0.418; fade weights u=0.916444, v=0.950882; bilinear blend → -0.31593.
+
+The fade curve 6t⁵-15t⁴+10t³ exists to make the field C² continuous at cell boundaries. Both its first and second derivatives vanish at t=0 and t=1, so neither the value nor its slope jumps as you cross into the next cell. Use a plain lerp and you get a visible axis-aligned grid, which becomes glaring once you take derivatives for a normal map.<｜end▁of▁sentence｜>

+Requests HTTP Library
+~~~~~~~~~~~~~~~~~~~~~
+
+Requests is an HTTP library, written in Python, for human beings.
+Basic GET usage:
+
+   >>> import requests
+   >>> r = requests.get('https://www.python.org')
+   >>> r.status_code
+   200
+   >>> b'Python is a programming language' in r.content
+   True
+
+... or POST:
+
+   >>> payload = dict(key1='value1', key2='value2')
+   >>> r = requests.post('https://httpbin.org/post', data=payload)
+   >>> print(r.text)
+   {
+     ...
+     "form": {
+       "key1": "value1",
+       "key2": "value2"
+     },
+     ...
+   }
+
+The other HTTP methods are supported - see `requests.api`. Full documentation
+is at .

+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE
+...
+
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+
+
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by ), you MUST output your complete reasoning inside ... BEFORE any tool calls or final response.
+
+Otherwise, output directly after  with tool calls or final response.
+

+<｜begin▁of▁sentence｜>You are an autonomous software engineering assistant. The working directory is a checkout of webgl-fundamentals. Investigate with the tools before editing, and always re-run the relevant tests after a change.
+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE
+...
+
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+
+
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by ), you MUST output your complete reasoning inside ... BEFORE any tool calls or final response.
+
+Otherwise, output directly after  with tool calls or final response.
+
+### Available Tool Schemas
+

Returns the file contents with 1-indexed line numbers.", "parameters": {"type": "object", "properties": {"path": {"type": "string", "description": "Path relative to the repository root"}, "offset": {"type": "integer", "description": "First line to read (1-indexed)"}, "limit": {"type": "integer", "description": "Maximum number of lines to read"}}, "required": ["path"]}}

+<｜Assistant｜>Green. Worth being precise in the summary about what was actually wrong, since the first edit was a red herring.Fixed. The failure in `webgl/lessons/resources/webgl-state-diagram/buffer-ui.js` was a missing input normalisation, not the refactor I first assumed — the sibling module in `webgl/lessons/resources/webgl-resizing-the-canvas.module.js` already normalises before dispatch and this one skipped it. One edit, `npm test` is green.
+
+The first edit I made (the guard comment) turned out to be unrelated; I left it in since it documents the invariant, but say the word and I'll drop it.<｜end▁of▁sentence｜>

+Abborrartade fiskar (Perciformes) är den artrikaste ordningen bland ryggradsdjuren, och utgör en mångsidig och heterogen grupp fiskar. De abborrartade fiskarna utmärks av taggiga fenstrålar, två ryggfenor, att de saknar fettfena, har simblåsa, och att stjärtens fenstrålar aldrig är flera än 17.
+
+De flesta arterna lever i saltvatten utefter tempererade och tropiska havskuster. De övriga lever pelagiskt i oceaner eller är sötvattenfiskar: omkring 2 200 av de arter som normalt förekommer i sötvatten lever dock i saltvatten under åtminstone en del av sitt liv.
+
+Av de många familjerna är smörbultarna (Gobiidae) artrikast med minst 1 875 arter, följd av cikliderna (Cichlidae) med 1 300 arter och läppfiskarna (Labridae) med 500 arter.
+
+Systematik 
+
+Ordningen omfattar 19 underordningar, 156 familjer, cirka 1 500 släkten och mer än 10 000 arter.
+
+Underordningar 
+ Kirurgfisklika fiskar – Acanthuroidei
+ Labyrintfiskar – Anabantoidei
+ Slemfisklika fiskar – Blennioidei
+ Sjökockslika fiskar – Callionymoidei
+ Ormhuvudfiskar – Channoidei (monotypiskt)
+ Elassomatoidei (monotypiskt)
+ Dubbelsugarfiskar – Gobiesocidei (monotypiskt)
+ Smörbultslika fiskar – Gobioidei
+ Icosteoidei (monotypiskt)
+ Krokhuvudfiskar – Kurtoidei (monotypiskt)
+ Läppfisklika fiskar – Labroidei
+ Notothenioider – Notothenioidei
+ Abborrlika fiskar – Percoidei
+ Pholidichthyoidei
+ Makrillika fiskar – Scombroidei
+ Scombrolabracoidei (monotypiskt)
+ Smörfisklika fiskar – Stromateoidei
+ Fjärsinglika fiskar – Trachinoidei

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate 2D Perlin noise at the point inside cell (5,0) with local coordinates (0.721, 0.843). The four corner gradients are g00=(-1, -1), g10=(1, 0), g01=(-1, 0), g11=(0, 1). Show the steps, and explain what the fade curve is for.<｜Assistant｜>Perlin noise is dot products of corner gradients with corner-to-point offsets, blended by a smooth curve.
+
+Offset vectors from each corner to the sample point:
+  d00 = (0.721, 0.843)   d10 = (-0.279, 0.843)
+  d01 = (0.721, -0.157)   d11 = (-0.279, -0.157)
+
+Corner contributions (gradient · offset):
+  n00 = (-1, -1)·(0.721,0.843) = -1.564
+  n10 = (1, 0)·(-0.279,0.843) = -0.279
+  n01 = (-1, 0)·(0.721,-0.157) = -0.721
+  n11 = (0, 1)·(-0.279,-0.157) = -0.157
+
+Fade curve 6t⁵-15t⁴+10t³:
+  u = fade(0.721) = 0.863569
+  v = fade(0.843) = 0.969842
+
+Bilinear blend using the faded weights:
+  nx0 = lerp(n00, n10, u) = -0.454314
+  nx1 = lerp(n01, n11, u) = -0.233947
+  value = lerp(nx0, nx1, v) = -0.240593
+
+Why fade and not plain lerp: the noise value must be C² across cell boundaries or the derivative jumps and you see a visible grid. 6t⁵-15t⁴+10t³ has f(0)=0, f(1)=1 and *both* first and second derivatives zero at the ends, so gradients and curvature match across the seam. Perlin's original 1985 version used 3t²-2t³, which is only C¹ — that is why the 1985 noise shows faint grid artefacts under a normal map and the 2002 'improved' version does not.
+
+With a plain linear blend (u = 0.721) the value here would be -0.365092 instead of -0.240593 — a small difference at one sample, but discontinuous in slope at every cell edge across the whole field.noise(5+0.721, 0+0.843) = **-0.240593**
+
+Steps: corner dots n00=-1.564, n10=-0.279, n01=-0.721, n11=-0.157; fade weights u=0.863569, v=0.969842; bilinear blend → -0.240593.
+
+The fade curve 6t⁵-15t⁴+10t³ exists to make the field C² continuous at cell boundaries. Both its first and second derivatives vanish at t=0 and t=1, so neither the value nor its slope jumps as you cross into the next cell. Use a plain lerp and you get a visible axis-aligned grid, which becomes glaring once you take derivatives for a normal map.<｜end▁of▁sentence｜>

+
+## `create()` 🧪 
+
+```tsx
+const renderer = ReactThreeTestRenderer.create(element, options)
+```
+
+Create a ReactThreeTestRenderer instance with a passed `three` element e.g. ``. By default, it won't create an actual `THREE.WebGLRenderer` and there will be no loop. But it will still render the complete scene graph. Returns the properties below.
+
+#### CreateOptions
+
+```ts
+// RenderProps is from react-three-fiber
+interface CreateOptions extends RenderProps {
+  width?: number // width of canvas
+  height?: number // height of canvas
+}
+```
+
+### `scene` 
+
+```tsx
+renderer.scene
+```
+
+Returns the root “react three test instance” object that is useful for making assertions. You can use it to find other “test instances” deeper below.
+
+### `getInstance()` 
+
+```tsx
+renderer.getInstance()
+```
+
+Return the instance corresponding to the root three element, if available. This will not work if the root element is a function component because they don’t have instances.
+
+### `toTree()` 
+
+```tsx
+renderer.toTree()
+```
+
+Returns an object representing the rendered tree similar to [`react-test-renderer`](https://reactjs.org/docs/test-renderer.html#overview). This will include all elements written as react components.
+
+### `toGraph()` 
+
+```tsx
+renderer.toGraph()
+```
+
+Returns an object representing the [`scene graph`](https://threejs.org/manual/#en/scenegraph). This will not include all elements such as ones that use `attach`.
+
+### `fireEvent()` 
+
+```tsx
+renderer.fireEvent(testInstance, eventName, mockEventData)
+```
+
+Native method to fire events on the specific part of the rendered tree through passing an element within the tree and an event name. The third argument is appended to the [`MockSyntheticEvent`](#create-fireevent-mocksyntheticevent) passed to the event handler.
+
+Event names follow camelCase convention (e.g. `pointerUp`), or you can pass event handler name instead (e.g. `onPointerUp`).
+
+#### `MockSyntheticEvent` 
+
+```ts
+type MockSyntheticEvent = {
+  camera: Camera // the default camera of the rendered scene
+  stopPropagation: () => void
+  target: ReactThreeTestInstance
+  currentTarget: ReactThreeTestInstance
+  sourceEvent: MockEventData
+  ...mockEventData
+}
+```
+
+### `advanceFrames()` 
+
+```tsx
+renderer.advanceFrames(frames, delta)
+```
+
+Native method to advance the frames (therefore running subscribers to the GL Render loop such as `useFrame`). Requires an amount of frames to advance by & a parameter of delta to pass to the subscribers creating a more controlled testing environment.
+
+### `update()` 
+
+```tsx
+renderer.update(element)
+```
+
+Rerender the tree with the new root element. This simulates a react update at the update, thus updating the children below. If the new element has the same type and key as the previous element, the tree will be updated.
+
+### `unmount()` 
+
+```tsx
+renderer.unmount()
+```
+
+Unmount the tree, triggering the appropriate lifecycle events.
+
+---
+
+## `act()` ⚛️ 
+
+```tsx
+ReactThreeTestRenderer.act(callback)
+```
+
+Similar to the [`act()` in `react-test-renderer`](https://reactjs.org/docs/test-renderer.html#testrendereract). `ReactThreeTestRenderer.act` prepares a component for assertions. Unlike `react-test-renderer` you do not have to wrap calls to `ReactThreeTestRenderer.create` and `renderer.update`.
+
+#### Act example (using jest)
+
+```tsx
+import ReactThreeTestRenderer from '@react-three/test-renderer'
+
+const Mesh = () => {
+  const meshRef = React.useRef()
+  useFrame((_, delta) => {
+    meshRef.current.rotation.x += delta
+  })
+
+  return (
+    
+      
+      
+    
+  )
+}
+
+const renderer = await ReactThreeTestRenderer.create()
+
+expect(renderer.scene.children[0].instance.rotation.x).toEqual(0)
+
+await ReactThreeTestRenderer.act(async () => {
+  await renderer.advanceFrames(2, 1)
+})
+
+expect(renderer.scene.children[0].instance.rotation.x).toEqual(2)
+```

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>CSS `cubic-bezier(0.26, 0.26, 0.14, -0.17)`. The browser needs the eased value at progress x = 0.26. Since the curve is parameterised by t, not x, show how to invert it and give y.<｜Assistant｜>The subtlety: `cubic-bezier(x1,y1,x2,y2)` defines a 2D curve with P0=(0,0) and P3=(1,1). Animation progress is the *x* coordinate, but the curve is parameterised by t, and x ≠ t unless the curve is linear. So you must solve B_x(t) = 0.26 for t first, then evaluate B_y(t).
+
+B_x(t) = 3(1-t)²t·0.26 + 3(1-t)t²·0.14 + t³
+
+Newton-Raphson, seeded with t = x = 0.26 (a good seed because x is monotone in t and close to it for well-behaved easings):
+  iter 0: t=0.26  f(t)=B_x(t)-x=-0.110361  f'(t)=0.463008
+  iter 1: t=0.498356  f(t)=B_x(t)-x=0.0139173  f'(t)=0.657051
+  iter 2: t=0.477174  f(t)=B_x(t)-x=0.000387852  f'(t)=0.62104
+  iter 3: t=0.47655  f(t)=B_x(t)-x=3.14369e-07  f'(t)=0.620033
+  iter 4: t=0.476549  f(t)=B_x(t)-x=2.06779e-13  f'(t)=0.620033
+  converged t = 0.476549
+
+Now the y coordinate:
+  B_y(t) = 3(1-t)²t·0.26 + 3(1-t)t²·-0.17 + t³ = 0.149446
+
+Newton is what real engines use, falling back to bisection when the derivative gets small — which happens when x1 or x2 sit near 0 or 1 and the curve has a near-vertical segment. Note also that y is allowed outside [0,1] (that is how overshoot/anticipation easings work) while x is clamped to [0,1] to keep the curve a function of progress.y = **0.149446** at x = 0.26 (solved t = 0.476549).
+
+The step people miss is that the cubic-bezier parameter t is *not* the animation progress x. You have to invert B_x(t) = x numerically — Newton-Raphson seeded at t = x converges in 5 iterations here — and only then evaluate B_y(t).
+
+y stays within [0,1], so this easing does not overshoot.<｜end▁of▁sentence｜>

+- Show statistics about the currently loaded file
+- Specify URL parameters to modify behavior on load
+
+## Usage
+
+### Controls
+
+`click + drag` : Rotate model
+
+`shift + drag` \
+`middle mouse button + drag` : Pan camera
+
+`scroll` \
+`right click + drag` : Zoom camera
+
+`GUI` : Use to change models and settings
+
+### Change glTF model
+
+- Choose one of the glTF models in the selection list
+- Drag and drop glTF files into viewer
+
+### Change the environment map
+
+- Drag and drop a .hdr panorama file
+
+### URL parameters
+
+URL parameters are added at the end of the sample viewer URL: \
+`?key=value&another_key=another_value`
+
+Possible parameters:
+
+- `model=URL_to_file`: Load glTF/glb from specified URL
+- `noUI`: Disable UI
+- `yaw=90`: Orbit the camera around the model along the Y-axis in degrees. With 90 degrees you look at the model from the left side.
+- `pitch=90`: Orbit the camera around the model along the X-axis in degrees. With 90 degrees you look at the model from the top. Value range: -90 to 90
+- `distance=5`: The models gets smaller with positive and bigger with negative numbers. Relative to the initial camera position.
+
+## Setup
+
+For local usage and debugging, please follow these instructions:
+
+1. Checkout the [`main`](../../tree/main) branch
+
+2. Pull the submodule for the required [glTF-Sample-Renderer](https://github.com/KhronosGroup/glTF-Sample-Renderer) `git submodule update  --init --recursive`
+
+3. Build the web app
+    - run `npm install`
+    - start a demo in the browser with `npm run dev`, and open http://localhost:8000.
+
+When making changes, the project is automatically rebuilt and the `./dist` directory is populated with the web app. This directory contains all files necessary for deployment to a webserver.
+
+## Debugging
+
+- Requirements
+    - [Visual Studio Code](https://code.visualstudio.com/) or [vscodium](https://github.com/VSCodium/vscodium)
+    - [Chrome](https://www.google.com/chrome/) or [Firefox](https://www.mozilla.org/en-US/firefox/new/)
+- Install the [Debugger for Chrome](https://marketplace.visualstudio.com/items?itemName=msjsdiag.debugger-for-chrome) or [Debugger for Firefox](https://marketplace.visualstudio.com/items?itemName=hbenl.vscode-firefox-debug) extension for Visual Studio Code
+- Open the project directory in Visual Studio Code and select `Debug->Add Configuration->Chrome` or `Debug->Add Configuration->Firefox` so the `.vscode/launch.json` file is created.
+- For chrome: Append `/dist` to `${workspaceFolder}` in the `launch.json` file
+- `Debug->Start Debugging` should now launch a Chrome or Firefox window with the sample viewer and VS Code breakpoints should be hit.
+
+### Known Issues
+
+npm install / npm run dev give the following warnings:
+
+The following warning comes from a thirdparty and does not affect sample viewer since the mentioned line 179 is never executed.
+
+```
+(!) "this" has been rewritten to "undefined"
+https://rollupjs.org/troubleshooting/#error-this-is-undefined
+node_modules/iobuffer/lib-esm/text-encoding-polyfill.js
+177:     : typeof self !== 'undefined'

+               ^
+180: //# sourceMappingURL=text-encoding-polyfill.js.map
+```
+
+The following warning is caused by an old bulma version, which buefy-next currently depends on.
+This should be fixed in an upcoming release: https://github.com/ntohq/buefy-next/issues/208
+
+```

+
+## 开发者要求
+
+虽然 tween.js *不*需要依赖 node.js 运行，但我们使用 node.js 来进行开发。所以我们需要先 [安装 node.js](https://nodejs.org/en/download/)，然后才能在库中工作。
+
+Node.js 包括我们用来运行脚本的 npm 工具，例如打包、运行测试等的脚本。在你尝试运行下面详述的任何步骤之前，请确保它在你的系统中正常工作。
+
+安装 node.js 后，克隆 tween.js 存储库：
+
+```bash
+git clone https://github.com/tweenjs/tween.js.git
+```
+
+进入该文件夹：
+
+```bash
+cd tween.js
+```
+
+并运行脚本来安装开发依赖项：
+
+```bash
+npm install
+```
+
+或者分三行：
+
+```bash
+git clone https://github.com/tweenjs/tween.js.git
+cd tween.js
+npm install
+```
+
+`npm install` 成功完成后，尝试运行测试：
+
+```bash
+npm test
+```
+
+如果你在运行上述任何步骤时遇到问题，请尝试使用你选择的搜索引擎搜索错误文本。这通常是最快的解决方法，因为很多人可能已经遇到过同样的问题。
+
+## 测试
+
+`test` 目录中有一套自动化测试。
+
+这些可以快速发现代码上的回归，在添加新功能或更改代码以修复 Bug 时很有用；我们不想引入新的 Bugs！自动化测试还会发现风格问题，这有助于我们保持库的凝聚力。
+
+要运行测试，请输入：
+
+```bash
+npm test
+```
+
+你应该在更改库中的代码后运行测试。如果你更改测试描述的行为，测试将不会通过，你将得到指向失败测试的错误。 这可能是因为...
+
+- 你忽略了一些东西，或者你的代码有错误，或者...
+- 库或测试本身是错误的
+
+以上两种情况，发生频率更高的是第一个，但第如果二个发生了，可能是边缘情况。
+
+**自动化测试通过之后，你应该做的另一件事是运行 `examples` 文件夹中的示例**。有种情况很少见，但可能会发生：你的更改引入了自动测试未检查的外观差异，注意到这一点的唯一方法是运行示例并让人工发现输出中的差异。如果你不想签出库的两个副本，可以查看[在线例子](https://github.com/tweenjs/tween.js#examples)。
+
+### 单元测试
+
+测试用例在 `src/tests.ts` 文件中。
+
+测试使用 [nodeunit](https://www.npmjs.com/package/nodeunit) 执行。
+
+**TODO:** 如果在浏览器中打开 `test/unit/nodeunit.html`，测试也应该能够正常运行，但是现在已经被损坏。有一个 [打开的问题](https://github.com/tweenjs/tween.js/issues/307) 可以使他们再次工作。
+
+### 代码风格和 lint 测试
+
+我们使用 [JSCS](http://jscs.info/) 和 [JSHint](http://jshint.com/) 来保证代码风格的��一。
+
+要自动格式化代码并报告不可被格式化的代码片段的任何错误，请运行：
+
+```base
+npm run test-lint
+```
+
+Prettier 规则在 `.prettierrc.js` 中，ESLint 规则在 `.eslintrc.js` 中。
+
+### 其他类型的测试
+
+我们想回归测试性能，即如果更改使运行变得更慢，或者简单地测试性能，那么我们可以比较不同浏览器之间相同代码的性能。
+
+有一个[open issue](https://github.com/tweenjs/discuss/issues/3)来跟踪这方面的工作，但我们还没有取得进展。请求帮助！ :-)
+
+## 持续集成
+
+我们使用 GitHub Actions 进行持续集成，以便为每个 pull request 运行构建和测试。 `.github/workflows/tests.yml` 文件告诉 GitHub 要运行什么；在我们的例子中，我们在该文件中指定的操作系统和 Node.js 版本中运行 `npm install`，然后运行 `npm test`。
+
+**TODO**：将 macOS 和 Windows 添加到运行测试的操作系统。 请求帮助！ :)
+
+## 发布流程
+
+目前发布过程是手动的。
+
+当准备好在 `master` 分支上发布时，确保没有未提交的更改，然后运行 `npm run release:patch` 发布一个新版本，其补丁号已被修改，`npm run release:minor` ，修改 minor 版本号并发布一个新版本，或者 `npm run release:major` 修改 major 版本号并发布一个新版本。
+
+Tip: 请参阅 [semver.org](https://semver.org/) 和 [npm-semver](https://docs.npmjs.com/misc/semver) 文档以了解语义版本控制。

+
+It is positive, so q0 and q1 are already in the same hemisphere and no sign flip is needed.

+Norm² = 1 — unit, as slerp guarantees (unlike nlerp, which needs renormalising).slerp(q0, q1, 0.79) = [0.218903, 0.623327, -0.648266, -0.378544]
+
+Steps: dot = 0.71932, already on the short arc; θ = 0.767973 rad; weights s0 = 0.231152, s1 = 0.820751.
+
+The sign check is the part that bites in practice: without it the rotation takes the long path whenever the two quaternions land in opposite hemispheres, which looks like a sudden 360° flip mid-animation.<｜end▁of▁sentence｜>

+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE
+...
+
+<｜DSML｜invoke name="$TOOL_NAME2">

+
+
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by ), you MUST output your complete reasoning inside ... BEFORE any tool calls or final response.

+110	    """The flask object implements a WSGI application and acts as the central
+111	    object.  It is passed the name of the module or package of the
+112	    application.  Once it is created it will act as a central registry for
+113	    the view functions, the URL rules, template configuration and much more.
+114	
+115	    The name of the package is used to resolve resources from inside the
+116	    package or the folder the module is contained in depending on if the
+117	    package parameter resolves to an actual python package (a folder with
+118	    an :file:`__init__.py` file inside) or a standard module (just a ``.py`` file).
+119	
+120	    For more information about resource loading, see :func:`open_resource`.
+121	
+122	    Usually you create a :class:`Flask` instance in your main module or
+123	    in the :file:`__init__.py` file of your package like this::
+124	
+125	        from flask import Flask
+126	        app = Flask(__name__)
+127	
+128	    .. admonition:: About the First Parameter
+129	
+130	        The idea of the first parameter is to give Flask an idea of what
+131	        belongs to your application.  This name is used to find resources
+132	        on the filesystem, can be used by extensions to improve debugging
+133	        information and a lot more.
+134	
+135	        So it's important what you provide there.  If you are using a single
+136	        module, `__name__` is always the correct value.  If you however are
+137	        using a package, it's usually recommended to hardcode the name of
+138	        your package there.
+139	
+140	        For example if your application is defined in :file:`yourapplication/app.py`
+141	        you should create it with one of the two versions below::
+142	
+143	            app = Flask('yourapplication')
+144	            app = Flask(__name__.split('.')[0])
+145	
+146	        Why is that?  The application will work even with `__name__`, thanks
+147	        to how resources are looked up.  However it will make debugging more
+148	        painful.  Certain extensions can make assumptions based on the
+149	        import name of your application.  For example the Flask-SQLAlchemy
+150	        extension will look for the code in your application that triggered
+151	        an SQL query in debug mode.  If the import name is not properly set
+152	        up, that debugging information is lost.  (For example it would only
+153	        pick up SQL queries in `yourapplication.app` and not
+154	        `yourapplication.views.frontend`)
+155	
+156	    .. versionadded:: 0.7
+157	       The `static_url_path`, `static_folder`, and `template_folder`
+158	       parameters were added.
+159	
+160	    .. versionadded:: 0.8
+161	       The `instance_path` and `instance_relative_config` parameters were
+162	       added.

+169	
+170	    .. versionadded:: 1.0
+171	       The ``subdomain_matching`` parameter was added. Subdomain
+172	       matching needs to be enabled manually now. Setting
+173	       :data:`SERVER_NAME` does not implicitly enable it.
+174	
+175	    :param import_name: the name of the application package
+176	    :param static_url_path: can be used to specify a different path for the
+177	                            static files on the web.  Defaults to the name
+178	                            of the `static_folder` folder.
+179	    :param static_folder: The folder with static files that is served at
+180	        ``static_url_path``. Relative to the application ``root_path``
+181	        or an absolute path. Defaults to ``'static'``.
+182	    :param static_host: the host to use when adding the static route.
+183	        Defaults to None. Required when using ``host_matching=True``
+184	        with a ``static_folder`` configured.
+185	    :param host_matching: set ``url_map.host_matching`` attribute.
+186	        Defaults to False.
+187	    :param subdomain_matching: consider the subdomain relative to
+188	        :data:`SERVER_NAME` when matching routes. Defaults to False.
+189	    :param template_folder: the folder that contains the templates that should
+190	                            be used by the application.  Defaults to
+191	                            ``'templates'`` folder in the root path of the
+192	                            application.
+193	    :param instance_path: An alternative instance path for the application.
+194	                          By default the folder ``'instance'`` next to the
+195	                          package or module is assumed to be the instance
+196	                          path.
+197	    :param instance_relative_config: if set to ``True`` relative filenames
+198	                                     for loading the config are assumed to
+199	                                     be relative to the instance path instead
+200	                                     of the application root.
+201	    :param root_path: The path to the root of the application files.
+202	        This should only be set manually when it can't be detected
+203	        automatically, such as for namespace packages.

+============================== 14 passed in 0.39s ==============================<｜Assistant｜>Green. Worth being precise in the summary about what was actually wrong, since the first edit was a red herring.Fixed. The failure in `src/flask/app.py` was a missing input normalisation, not the bug I first assumed — the sibling module in `tests/test_json_tag.py` already normalises before dispatch and this one skipped it. One edit, `python -m pytest -q` is green.
+
+The first edit I made (the guard comment) turned out to be unrelated; I left it in since it documents the invariant, but say the word and I'll drop it.<｜end▁of▁sentence｜>

+Alkeny – organiczne związki chemiczne z grupy węglowodorów nienasyconych, w których występuje jedno podwójne wiązanie chemiczne między atomami węgla (). Razem ze związkami, które posiadają dwa lub więcej wiązań podwójnych (polienami, takimi jak dieny, trieny itd.) oraz z analogami pierścieniowymi (cykloalkenami i cyklopolienami) tworzą grupę olefin. Mają więcej izomerów i są bardziej aktywne niż alkany. Wraz ze zwiększającą się długością łańcucha węglowego maleje ich reaktywność. Można je otrzymać z ropy naftowej, a w laboratorium w reakcji eliminacji fluorowca z halogenków alkilowych lub przez  alkoholi. Ich wzór ogólny to .
+
+Nazewnictwo 
+Nazwy alkenów są tworzone z nazw odpowiednich alkanów. Z nazwy alkanu posiadającego ten sam szkielet węglowy usuwa się końcówkę -an i dodaje końcówkę -en, przed którą umieszcza się lokant, wskazujący przy którym atomie węgla występuje podwójne wiązanie. Na przykład:
+ heksan i 
+
+Lokant można pominąć, gdy jest on równy 1 (wtedy, gdy wiązanie podwójne występuje na początku szkieletu węglowego).
+
+Nazewnictwo dienów i polienów jest tworzone analogicznie z odpowiednio większą liczbą lokantów i końcówką -dien, -trien, -tetraen itd. Na przykład:
+ buta-1,3-dien
+
+W literaturze spotyka się też nazewnictwo, które różni się od nomenklatury IUPAC tym, że lokanty występują przed nazwą. Przykładowo:
+ 2-heksen; 1,3-butadien.
+
+Izomeria 
+Alkeny o większej liczbie atomów węgla niż propen mogą istnieć w kilku formach izomerycznych na skutek rozgałęzienia łańcucha węglowego, zmiany umiejscowienia podwójnych wiązań chemicznych i występowaniu zjawiska izomerii geometrycznej. Eten i propen nie posiadają izomerów, a buten ma ich 4.
+
+Otrzymywanie 
+Alkeny otrzymuje się poprzez eliminację cząstki nieorganicznej z halogenopochodnych alkanów () lub alkoholi (dehydratacja), w krakingu, bądź reakcji uwodornienia alkinów.
+
+ Dehydratacja alkoholi. Reakcję prowadzi się w podwyższonej temperaturze w obecności katalizatora kwasowego, np. tlenku glinu lub kwasu siarkowego. W przypadku, gdy możliwe jest powstawanie różnych izomerów, produktem głównym jest ten, w którym wiązanie wielokrotne występuje między atomami węgla uboższymi w wodór (reguła Zajcewa, obowiązuje także dla dehydrohalogenacji).
+ Deaminacja amin (eliminacja Hofmanna), w wyniku której otrzymuje się alkeny o położeniu wiązania podwójnego przeciwnie do reguły Zajcewa.
+ Dehydrohalogenacja halogenoalkanów w środowisku zasadowym w podwyższonej temperaturze, np. wobec zasady potasowej.
+ Reakcja wicynalnych (tj. zawierających atomy halogenu w pozycjach sąsiednich) dihalogenoalkanów z cynkiem.
+ Otrzymywanie na skalę przemysłową z wykorzystaniem metody krakowania wyższych alkanów.
+ W ropach naftowych występują w nieznacznych ilościach, toteż większość alkenów stosowanych w przemyśle pochodzi z przeróbki (krakingu niskociśnieniowego, tzw. olefinowego) różnych frakcji ropy, głównie benzyny ciężkiej.
+
+Charakterystyczne reakcje 
+Alkeny są trwałymi związkami, które jednak są bardziej reaktywne od alkanów.
+Podlegają one m.in.: reakcjom polimeryzacji winylowej oraz reakcjom addycji np.: przyłączania gazowego chloru, chlorowodoru, wody.
+
+Przykładowa reakcja addycji chloru do etenu:
+
+Alkeny o większej ilości wiązań podwójnych 
+Alkeny z dwoma podwójnymi wiązaniami to dieny. Alkeny z więcej niż dwoma wiązaniami podwójnymi (trieny, tetraeny itd.) są ogólnie nazywane polienami.
+Dieny można podzielić na:
+ alleny zwane też dienami skumulowanymi, w których wiązania podwójne sąsiadują ze sobą,
+ dieny sprzężone, w których wiązania podwójne oddzielone są jednym wiązaniem pojedynczym,
+ dieny z izolowanym układem wiązań podwójnych, w których występują co najmniej 2 wiązania pojedyncze pomiędzy wiązaniami podwójnymi.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Cubic Bézier with control points P0=[-2.8, -0.69], P1=[-1.34, 4.65], P2=[-3.3, 2.36], P3=[4.29, 3.5]. Evaluate the curve at t=0.4 using de Casteljau, give the tangent there, and split the curve at that t.<｜Assistant｜>de Casteljau is repeated lerp. First level, lerp each adjacent pair at t=0.4:
+  A = lerp(P0,P1,0.4) = [-2.216, 1.446]
+  B = lerp(P1,P2,0.4) = [-2.124, 3.734]
+  C = lerp(P2,P3,0.4) = [-0.264, 2.816]
+Second level:
+  D = lerp(A,B,0.4) = [-2.1792, 2.3612]
+  E = lerp(B,C,0.4) = [-1.38, 3.3668]
+Third level:
+  P(t) = lerp(D,E,0.4) = [-1.85952, 2.76344]
+
+The tangent is the analytic derivative:
+  B'(t) = 3(1-t)²(P1-P0) + 6(1-t)t(P2-P1) + 3t²(P3-P2)
+        = 3·0.36·[1.46, 5.34] + 6·0.24·[-1.96, -2.29] + 3·0.16·[7.59, 1.14]
+        = [2.3976, 3.0168]
+Note D→E is parallel to that: E-D = [0.7992, 1.0056], and 3·(E-D) = [2.3976, 3.0168]. That is the useful identity — the last lerp segment is the tangent up to the factor 3.
+
+Splitting is free once you have the intermediate points: the left half is P0,A,D,P(t) and the right half is P(t),E,C,P3.P(0.4) = [-1.85952, 2.76344]
+
+Tangent B'(0.4) = [2.3976, 3.0168] (unit: [0.622185, 0.78287]).
+
+Split at t=0.4:
+  left  = [[-2.8, -0.69], [-2.216, 1.446], [-2.1792, 2.3612], [-1.85952, 2.76344]]
+  right = [[-1.85952, 2.76344], [-1.38, 3.3668], [-0.264, 2.816], [4.29, 3.5]]
+
+Both halves are exact cubic Béziers reproducing the original geometry — this is what adaptive flattening and `CurveUtils` subdivision rely on.<｜end▁of▁sentence｜>

+<｜Assistant｜>Green. Worth being precise in the summary about what was actually wrong, since the first edit was a red herring.Fixed. The failure in `playground/css-codesplit/vite.config.js` was a missing input normalisation, not the bug I first assumed — the sibling module in `packages/vite/src/node/__tests__/plugins/import.spec.ts` already normalises before dispatch and this one skipped it. One edit, `pnpm test` is green.
+
+The first edit I made (the guard comment) turned out to be unrelated; I left it in since it documents the invariant, but say the word and I'll drop it.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Slerp between unit quaternions
+  q0 = [0.135791, -0.671175, 0.625072, 0.374659]
+  q1 = [-0.288547, 0.85619, -0.252648, -0.346192]
+at t = 0.22 (XYZW order). Show the steps, including the sign handling, and give the interpolated quaternion.<｜Assistant｜>Dot product first: q0·q1 = -0.901462.
+
+It is negative. q and -q are the same rotation, but interpolating toward the negative representative takes the long way round the 4-sphere, so I negate q1 to [0.288547, -0.85619, 0.252648, 0.346192] and use |dot| = 0.901462. Skipping this is the classic slerp bug where the object spins the wrong way.
+
+θ = acos(0.901462) = 0.44766 rad (25.649°).
+sin θ = 0.432858.
+
+Weights:
+  s0 = sin((1-0.22)·θ)/sin θ = sin(0.349175)/0.432858 = 0.790382
+  s1 = sin(0.22·θ)/sin θ = sin(0.0984853)/0.432858 = 0.227156
+
+Result = 0.790382·q0 + 0.227156·q1' = [0.172872, -0.724973, 0.551436, 0.374763]
+Norm² = 1 — unit, as slerp guarantees (unlike nlerp, which needs renormalising).slerp(q0, q1, 0.22) = [0.172872, -0.724973, 0.551436, 0.374763]
+
+Steps: dot = -0.901462, negative so q1 is negated to stay on the short arc; θ = 0.44766 rad; weights s0 = 0.790382, s1 = 0.227156.
+
+The sign check is the part that bites in practice: without it the rotation takes the long path whenever the two quaternions land in opposite hemispheres, which looks like a sudden 360° flip mid-animation.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>For a dielectric with IOR 1.45, compute F0 and the Schlick-approximated Fresnel reflectance at 75° incidence. How close is Schlick to the exact Fresnel equations here?<｜Assistant｜>F0 is reflectance at normal incidence, from the Fresnel equations at θ=0:
+  F0 = ((n₁-n₂)/(n₁+n₂))² with n₁=1 (air), n₂=1.45
+     = ((1.45-1)/(1.45+1))² = (0.183673)² = 0.0337359
+
+Schlick:
+  F(θ) = F0 + (1 - F0)(1 - cos θ)⁵
+  cos 75° = 0.258819
+  (1 - 0.258819)⁵ = 0.223677
+  F = 0.0337359 + 0.966264·0.223677 = 0.249867

+Accuracy: Schlick is within about 1% of the exact Fresnel average for dielectrics across most of the range, with the largest relative error in the 75-80° band. It is built to be exact at both endpoints — θ=0 by construction, and θ=90° where the (1-cosθ)⁵ term reaches 1 and F → 1, which is the grazing-angle total reflection every surface shows.
+
+At 75° we are well into the grazing regime, where the ⁵ power is doing all the work.F0 = 0.0337359 (3.37% reflectance head-on).
+F(75°) = 0.249867 (25%).
+
+Schlick tracks the exact Fresnel equations to within roughly 1% for dielectrics, and is exact at both θ=0 and θ=90° by construction. It is the standard choice in real-time PBR — the error is far below other approximations in the pipeline.
+
+Note 75° is grazing: the (1-cosθ)⁵ term dominates and reflectance climbs steeply toward 1 from here. For metals this formulation does not apply directly: F0 becomes a per-channel tinted value from the complex refractive index rather than a single scalar.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>I'm building a BVH over 1,000,000 triangles for raycasting in a three.js scene. Compare the cost of a median split against a full SAH build, and tell me what to expect for query time.<｜Assistant｜>Two separate questions: build cost and query cost. They trade against each other.
+
+**Median split.** At each node, sort or nth_element along the widest axis and split at the median. Using nth_element the partition is O(k) for k primitives at that node. Total work per level is O(n), and the tree is balanced by construction so there are log₂(1,000,000) ≈ 19.93 levels. Build is O(n log n) ≈ 1,000,000 × 19.93 ≈ 19,931,568 primitive-touches.
+
+**SAH.** Evaluate the surface-area heuristic cost C = C_trav + (A_L/A)·N_L·C_isect + (A_R/A)·N_R·C_isect over candidate splits. Binned SAH with B bins (typically 12-32) costs one O(k) pass to fill bins plus O(B) to sweep, so it stays O(n log n) but with a constant factor of roughly 2-4× median. Full sweep SAH over all candidates is O(n log² n) and not worth it here.
+
+**Query.** This is where SAH pays. Median split balances *counts*, which is the wrong objective — what matters is the probability a ray hits a node, which by the surface-area measure is proportional to the node's surface area. SAH minimises expected traversal cost directly. In practice SAH gives 1.5-2× faster raycasts on typical mesh distributions, and much more than that on scenes with wildly varying triangle density, where median split cheerfully puts a dense cluster and a far-away stray triangle in one fat box.
+
+Expected query is O(log n) ≈ 19.93 node visits for a well-built tree, but that is an average, not a bound — worst case is still O(n) for a ray that grazes many boxes.**Build:** both are O(n log n). For 1,000,000 triangles that is ≈19,931,568 primitive-touches (19.93 levels). Binned SAH costs about 2-4× median split in wall time; full-sweep SAH is O(n log² n) and not worth it at this size.
+
+**Query:** SAH wins, typically 1.5-2× faster rays, and considerably more on scenes with uneven triangle density. The reason is that median split balances triangle *counts*, but ray-hit probability scales with a node's *surface area* — so a balanced tree can still be a slow tree.
+
+**Recommendation:** binned SAH with 16 bins. You pay build cost once and amortise it over every ray. Only prefer median split if you rebuild every frame for deforming geometry.
+
+Expect ≈19.93 node visits per ray on average — but that is an average, not a bound; grazing rays can still degenerate toward O(n).<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate 2D Perlin noise at the point inside cell (0,4) with local coordinates (0.843, 0.236). The four corner gradients are g00=(1, 0), g10=(-1, 0), g01=(0, 1), g11=(0, -1). Show the steps, and explain what the fade curve is for.<｜Assistant｜>Perlin noise is dot products of corner gradients with corner-to-point offsets, blended by a smooth curve.
+
+Offset vectors from each corner to the sample point:
+  d00 = (0.843, 0.236)   d10 = (-0.157, 0.236)
+  d01 = (0.843, -0.764)   d11 = (-0.157, -0.764)
+
+Corner contributions (gradient · offset):
+  n00 = (1, 0)·(0.843,0.236) = 0.843
+  n10 = (-1, 0)·(-0.157,0.236) = 0.157
+  n01 = (0, 1)·(0.843,-0.764) = -0.764
+  n11 = (0, -1)·(-0.157,-0.764) = 0.764
+
+Fade curve 6t⁵-15t⁴+10t³:
+  u = fade(0.843) = 0.969842
+  v = fade(0.236) = 0.0893044
+
+Bilinear blend using the faded weights:
+  nx0 = lerp(n00, n10, u) = 0.177688
+  nx1 = lerp(n01, n11, u) = 0.717919
+  value = lerp(nx0, nx1, v) = 0.225933
+
+Why fade and not plain lerp: the noise value must be C² across cell boundaries or the derivative jumps and you see a visible grid. 6t⁵-15t⁴+10t³ has f(0)=0, f(1)=1 and *both* first and second derivatives zero at the ends, so gradients and curvature match across the seam. Perlin's original 1985 version used 3t²-2t³, which is only C¹ — that is why the 1985 noise shows faint grid artefacts under a normal map and the 2002 'improved' version does not.
+
+With a plain linear blend (u = 0.843) the value here would be 0.325921 instead of 0.225933 — a small difference at one sample, but discontinuous in slope at every cell edge across the whole field.noise(0+0.843, 4+0.236) = **0.225933**
+
+Steps: corner dots n00=0.843, n10=0.157, n01=-0.764, n11=0.764; fade weights u=0.969842, v=0.0893044; bilinear blend → 0.225933.
+
+The fade curve 6t⁵-15t⁴+10t³ exists to make the field C² continuous at cell boundaries. Both its first and second derivatives vanish at t=0 and t=1, so neither the value nor its slope jumps as you cross into the next cell. Use a plain lerp and you get a visible axis-aligned grid, which becomes glaring once you take derivatives for a normal map.<｜end▁of▁sentence｜>

+  z = w1*z2 + x1*y2 - y1*x2 + z1*w2

+
+Norm check: x²+y²+z²+w² = 1. Unit to floating point, as it must be — the product of two unit quaternions is unit, so no renormalisation is needed here beyond drift control over many successive multiplications.
+
+Order: quaternion composition applies right-to-left on vectors, since (q1*q2) v (q1*q2)⁻¹ = q1 (q2 v q2⁻¹) q1⁻¹. So q2 acts first.q1 * q2 = (-0.463615, -0.645485, -0.173459, 0.581655) in XYZW order.
+
+Norm² = 1, so it is still a unit quaternion.
+
+The product applies **q2 first, then q1** — composition reads right-to-left, the same convention as matrix multiplication. In three.js `q1.multiply(q2)` gives exactly this, while `q1.premultiply(q2)` gives the other order.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You operate on the webgpu-samples codebase through tools. Prefer reading the surrounding code before making an edit. Never claim a fix works until a command confirms it.
+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE
+...
+
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+
+
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by ), you MUST output your complete reasoning inside ... BEFORE any tool calls or final response.
+
+Otherwise, output directly after  with tool calls or final response.
+

+<｜Assistant｜>Green. Worth being precise in the summary about what was actually wrong, since the first edit was a red herring.Fixed. The failure in `sample/blending/meta.ts` was a missing input normalisation, not the doc I first assumed — the sibling module in `sample/reversedZ/fragmentTextureQuad.wgsl` already normalises before dispatch and this one skipped it. One edit, `npm test` is green.

+The first edit I made (the guard comment) turned out to be unrelated; I left it in since it documents the invariant, but say the word and I'll drop it.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate 2D Perlin noise at the point inside cell (3,4) with local coordinates (0.313, 0.585). The four corner gradients are g00=(-1, 1), g10=(1, -1), g01=(-1, -1), g11=(1, 0). Show the steps, and explain what the fade curve is for.<｜Assistant｜>Perlin noise is dot products of corner gradients with corner-to-point offsets, blended by a smooth curve.
+
+Offset vectors from each corner to the sample point:
+  d00 = (0.313, 0.585)   d10 = (-0.687, 0.585)
+  d01 = (0.313, -0.415)   d11 = (-0.687, -0.415)
+
+Corner contributions (gradient · offset):
+  n00 = (-1, 1)·(0.313,0.585) = 0.272
+  n10 = (1, -1)·(-0.687,0.585) = -1.272
+  n01 = (-1, -1)·(0.313,-0.415) = 0.102
+  n11 = (1, 0)·(-0.687,-0.415) = -0.687
+
+Fade curve 6t⁵-15t⁴+10t³:
+  u = fade(0.313) = 0.180699
+  v = fade(0.585) = 0.656331
+
+Bilinear blend using the faded weights:
+  nx0 = lerp(n00, n10, u) = -0.00699925
+  nx1 = lerp(n01, n11, u) = -0.0405715
+  value = lerp(nx0, nx1, v) = -0.0290338
+
+Why fade and not plain lerp: the noise value must be C² across cell boundaries or the derivative jumps and you see a visible grid. 6t⁵-15t⁴+10t³ has f(0)=0, f(1)=1 and *both* first and second derivatives zero at the ends, so gradients and curvature match across the seam. Perlin's original 1985 version used 3t²-2t³, which is only C¹ — that is why the 1985 noise shows faint grid artefacts under a normal map and the 2002 'improved' version does not.
+
+With a plain linear blend (u = 0.313) the value here would be -0.172478 instead of -0.0290338 — a small difference at one sample, but discontinuous in slope at every cell edge across the whole field.noise(3+0.313, 4+0.585) = **-0.0290338**
+
+Steps: corner dots n00=0.272, n10=-1.272, n01=0.102, n11=-0.687; fade weights u=0.180699, v=0.656331; bilinear blend → -0.0290338.
+
+The fade curve 6t⁵-15t⁴+10t³ exists to make the field C² continuous at cell boundaries. Both its first and second derivatives vanish at t=0 and t=1, so neither the value nor its slope jumps as you cross into the next cell. Use a plain lerp and you get a visible axis-aligned grid, which becomes glaring once you take derivatives for a normal map.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a coding agent working inside the requests repository. Use the provided tools to inspect and modify the codebase. Verify your changes by running the project's checks before reporting completion.
+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE
+...
+
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+
+
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by ), you MUST output your complete reasoning inside ... BEFORE any tool calls or final response.
+
+Otherwise, output directly after  with tool calls or final response.
+
+### Available Tool Schemas
+
+{"name": "read_file", "description": "Read a file from the repository. Returns the file contents with 1-indexed line numbers.", "parameters": {"type": "object", "properties": {"path": {"type": "string", "description": "Path relative to the repository root"}, "offset": {"type": "integer", "description": "First line to read (1-indexed)"}, "limit": {"type": "integer", "description": "Maximum number of lines to read"}}, "required": ["path"]}}
+{"name": "edit_file", "description": "Replace an exact string in a file. old_string must match the file exactly and be unique.", "parameters": {"type": "object", "properties": {"path": {"type": "string", "description": "Path relative to the repository root"}, "old_string": {"type": "string", "description": "Exact text to replace"}, "new_string": {"type": "string", "description": "Replacement text"}}, "required": ["path", "old_string", "new_string"]}}
+{"name": "run_command", "description": "Run a shell command in the repository root and return its combined output.", "parameters": {"type": "object", "properties": {"command": {"type": "string", "description": "The command to run"}, "timeout_s": {"type": "integer", "description": "Timeout in seconds"}}, "required": ["command"]}}
+{"name": "grep", "description": "Search file contents with a regular expression.", "parameters": {"type": "object", "properties": {"pattern": {"type": "string", "description": "Regular expression"}, "path": {"type": "string", "description": "Directory to search"}, "glob": {"type": "string", "description": "Filter files by glob, e.g. *.ts"}}, "required": ["pattern"]}}
+{"name": "list_dir", "description": "List the entries of a directory.", "parameters": {"type": "object", "properties": {"path": {"type": "string", "description": "Directory path"}}, "required": ["path"]}}
+
+You MUST strictly follow the above defined tool name and parameter schemas to invoke tool calls.

Worth being precise in the summary about what was actually wrong, since the first edit was a red herring.Fixed. The failure in `tests/test_testserver.py` was a missing input normalisation, not the perf I first assumed — the sibling module in `src/requests/compat.py` already normalises before dispatch and this one skipped it. One edit, `python -m pytest -q` is green.
+
+The first edit I made (the guard comment) turned out to be unrelated; I left it in since it documents the invariant, but say the word and I'll drop it.<｜end▁of▁sentence｜>

+  q2 = (-0.308007, 0.360474, 0.831263, 0.290157)
+compute the Hamilton product q1 * q2 and confirm the result is still unit length. Which rotation does the product correspond to — applying q1 first or q2 first?<｜Assistant｜>Hamilton product, XYZW storage. The component formulas are
+  x = w1*x2 + x1*w2 + y1*z2 - z1*y2
+  y = w1*y2 - x1*z2 + y1*w2 + z1*x2
+  z = w1*z2 + x1*y2 - y1*x2 + z1*w2
+  w = w1*w2 - x1*x2 - y1*y2 - z1*z2
+
+x: -0.815207*-0.308007 + -0.23908*0.290157 + 0.48444*0.831263 - 0.208796*0.360474 = 0.509151
+y: -0.815207*0.360474 - -0.23908*0.831263 + 0.48444*0.290157 + 0.208796*-0.308007 = -0.0188695
+z: -0.815207*0.831263 + -0.23908*0.360474 - 0.48444*-0.308007 + 0.208796*0.290157 = -0.554039

+
+Norm check: x²+y²+z²+w² = 1. Unit to floating point, as it must be — the product of two unit quaternions is unit, so no renormalisation is needed here beyond drift control over many successive multiplications.
+
+Order: quaternion composition applies right-to-left on vectors, since (q1*q2) v (q1*q2)⁻¹ = q1 (q2 v q2⁻¹) q1⁻¹. So q2 acts first.q1 * q2 = (0.509151, -0.0188695, -0.554039, -0.658369) in XYZW order.
+
+Norm² = 1, so it is still a unit quaternion.
+
+The product applies **q2 first, then q1** — composition reads right-to-left, the same convention as matrix multiplication. In three.js `q1.multiply(q2)` gives exactly this, while `q1.premultiply(q2)` gives the other order.<｜end▁of▁sentence｜>
+
+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>CSS `cubic-bezier(0.81, 0.42, 0.45, 0.6)`. The browser needs the eased value at progress x = 0.75. Since the curve is parameterised by t, not x, show how to invert it and give y.<｜Assistant｜>The subtlety: `cubic-bezier(x1,y1,x2,y2)` defines a 2D curve with P0=(0,0) and P3=(1,1). Animation progress is the *x* coordinate, but the curve is parameterised by t, and x ≠ t unless the curve is linear. So you must solve B_x(t) = 0.75 for t first, then evaluate B_y(t).
+
+B_x(t) = 3(1-t)²t·0.81 + 3(1-t)t²·0.45 + t³
+
+Newton-Raphson, seeded with t = x = 0.75 (a good seed because x is monotone in t and close to it for well-behaved easings):
+  iter 0: t=0.75  f(t)=B_x(t)-x=-0.024375  f'(t)=0.675
+  iter 1: t=0.786111  f(t)=B_x(t)-x=0.00162364  f'(t)=0.767637
+  iter 2: t=0.783996  f(t)=B_x(t)-x=6.22263e-06  f'(t)=0.761762
+  iter 3: t=0.783988  f(t)=B_x(t)-x=9.22261e-11  f'(t)=0.76174
+  converged t = 0.783988
+
+Now the y coordinate:
+  B_y(t) = 3(1-t)²t·0.42 + 3(1-t)t²·0.6 + t³ = 0.766945
+
+Newton is what real engines use, falling back to bisection when the derivative gets small — which happens when x1 or x2 sit near 0 or 1 and the curve has a near-vertical segment. Note also that y is allowed outside [0,1] (that is how overshoot/anticipation easings work) while x is clamped to [0,1] to keep the curve a function of progress.y = **0.766945** at x = 0.75 (solved t = 0.783988).
+
+The step people miss is that the cubic-bezier parameter t is *not* the animation progress x. You have to invert B_x(t) = x numerically — Newton-Raphson seeded at t = x converges in 4 iterations here — and only then evaluate B_y(t).
+
+y stays within [0,1], so this easing does not overshoot.<｜end▁of▁sentence｜>

+# Flask
+
+Flask is a lightweight [WSGI] web application framework. It is designed
+to make getting started quick and easy, with the ability to scale up to
+complex applications. It began as a simple wrapper around [Werkzeug]
+and [Jinja], and has become one of the most popular Python web
+application frameworks.
+
+Flask offers suggestions, but doesn't enforce any dependencies or
+project layout. It is up to the developer to choose the tools and
+libraries they want to use. There are many extensions provided by the
+community that make adding new functionality easy.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Slerp between unit quaternions
+  q0 = [0.880998, 0.330422, -0.337309, 0.0297896]
+  q1 = [-0.624505, -0.324293, 0.702546, 0.106096]
+at t = 0.75 (XYZW order). Show the steps, including the sign handling, and give the interpolated quaternion.<｜Assistant｜>Dot product first: q0·q1 = -0.891156.
+
+It is negative. q and -q are the same rotation, but interpolating toward the negative representative takes the long way round the 4-sphere, so I negate q1 to [0.624505, 0.324293, -0.702546, -0.106096] and use |dot| = 0.891156. Skipping this is the classic slerp bug where the object spins the wrong way.
+
+θ = acos(0.891156) = 0.470911 rad (26.9812°).
+sin θ = 0.453698.
+
+Weights:
+  s0 = sin((1-0.75)·θ)/sin θ = sin(0.117728)/0.453698 = 0.258886
+  s1 = sin(0.75·θ)/sin θ = sin(0.353183)/0.453698 = 0.762371
+
+Result = 0.258886·q0 + 0.762371·q1' = [0.704182, 0.332773, -0.622925, -0.0731723]
+Norm² = 1 — unit, as slerp guarantees (unlike nlerp, which needs renormalising).slerp(q0, q1, 0.75) = [0.704182, 0.332773, -0.622925, -0.0731723]
+
+Steps: dot = -0.891156, negative so q1 is negated to stay on the short arc; θ = 0.470911 rad; weights s0 = 0.258886, s1 = 0.762371.
+
+The sign check is the part that bites in practice: without it the rotation takes the long path whenever the two quaternions land in opposite hemispheres, which looks like a sudden 360° flip mid-animation.<｜end▁of▁sentence｜>

+
+## Ways to Contribute
+
+There are multiple ways to contribute.
+
+### Reporting an issue
+
+Please [create an issue](https://github.com/nlohmann/json/issues/new/choose), assuming one does not already exist, and
+describe your concern. Note you need a [GitHub account](https://github.com/signup/free) for this.
+
+Clearly describe the issue:
+
+- If it is a bug, please describe how to **reproduce** it. If possible, attach a _complete example_ which demonstrates
+  the error. Please also state what you **expected** to happen instead of the error.
+- If you propose a change or addition, try to give an **example** what the improved code could look like or how to use
+  it.
+- If you found a compilation error, please tell us which **compiler** (version and operating system) you used and paste
+  the (relevant part of) the error messages to the ticket.
+
+Please stick to the provided issue template
+[bug report](https://github.com/nlohmann/json/blob/develop/.github/ISSUE_TEMPLATE/bug.yaml) if possible.
+
+### Reporting a security vulnerability
+
+You can report a security vulnerability according to our
+[security policy](https://github.com/nlohmann/json/security/policy).
+
+### Discussing a new feature
+
+For questions, feature or support requests, please
+[open a discussion](https://github.com/nlohmann/json/discussions/new). If you find a proposed answer satisfactory,
+please use the "Mark as answer" button to make it easier for readers to see what helped and for the community to filter
+for open questions.
+
+### Proposing a fix or an improvement
+
+Join an ongoing discussion or comment on an existing issue before starting to code. This can help to avoid duplicate
+efforts or other frustration during the later review.
+
+Create a [pull request](https://github.com/nlohmann/json/pulls?q=sort%3Aupdated-desc+is%3Apr+is%3Aopen) against the
+`develop` branch and follow the pull request template. In particular,
+
+- describe the changes in detail, both the what and why,
+- reference existing issues where applicable,
+- add tests to maintain 100% test coverage,
+- update the documentation as needed, and
+- ensure the source code is amalgamated.
+
+We describe all points in detail below.
+
+All contributions (including pull requests) must agree to the
+[Developer Certificate of Origin (DCO) version 1.1](https://developercertificate.org). This is exactly the same one
+created and used by the Linux kernel developers and posted on http://developercertificate.org/. This is a developer's
+certification that he or she has the right to submit the patch for inclusion into the project.
+
+## How to...
+
+### Describe your changes
+
+This library is primarily maintained as a spare-time project. As such, I cannot make any guarantee how quickly changes
+are merged and released. Therefore, it is very important to make the review as smooth as possible by explaining not only
+_what_ you changed, but _why_. This rationale can be very valuable down the road when improvements or bugs are discussed
+years later.
+
+### Reference an existing issue
+
+[Link a pull request to an issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/using-issues/linking-a-pull-request-to-an-issue)
+to clarify that a fix is forthcoming and which issue can be closed after merging. Only a few cases (e.g., fixing typos)
+do not require prior discussions.
+
+### Write tests
+
+The library has an extensive test suite that currently covers [100 %](https://coveralls.io/github/nlohmann/json) of the
+library's code. These tests are crucial to maintain API stability and give future contributors confidence that they do
+not accidentally break things. As Titus Winters aptly put it:
+
+> If you liked it, you should have put a test on it.
+
+#### Run the tests
+
+First, ensure the test suite runs before making any changes:
+
+```sh
+$ cmake -S. -B build
+$ cmake --build build -j 10
+$ ctest --test-dir build -j 10
+```
+
+The test suite should report:
+
+```
+100% tests passed, 0 tests failed out of 98
+```
+
+#### Add tests
+
+The tests are located in [`tests/src/unit-*.cpp`](https://github.com/nlohmann/json/tree/develop/tests/src) and contain
+[doctest assertions](https://github.com/doctest/doctest/blob/master/doc/markdown/assertions.md) like `CHECK`. The tests
+are structured along the features of the library or the nature of the tests. Usually, it should be clear from the
+context which existing file needs to be extended, and only very few cases require creating new test files.
+
+When fixing a bug, edit `unit-regression2.cpp` and add a section referencing the fixed issue.
+
+#### Exceptions
+
+When you test exceptions, please use `CHECK_THROWS_WITH_AS` which also takes the `what()` argument of the thrown
+exception into account.
+
+#### Coverage
+
+If test coverage decreases, an automatic warning comment will be posted on the pull request. You can access a code
+coverage report as an artifact to the “Ubuntu” workflow.
+
+### Update the documentation
+
+The [main documentation](https://json.nlohmann.me) of the library is generated from the files
+[`docs/mkdocs/docs`](https://github.com/nlohmann/json/blob/develop/docs/mkdocs/docs). This folder contains dedicated
+pages for [certain features](https://github.com/nlohmann/json/tree/develop/docs/mkdocs/docs/features), a list of
+[all exceptions](https://github.com/nlohmann/json/blob/develop/docs/mkdocs/docs/home/exceptions.md), and 
+[extensive API documentation](https://github.com/nlohmann/json/tree/develop/docs/mkdocs/docs/api) with details on every
+public API function.
+
+Build the documentation locally using:
+
+```shell
+make install_venv -C docs/mkdocs
+make serve -C docs/mkdocs
+```
+
+The documentation will then be available at . See the documentation of
+[mkdocs](https://www.mkdocs.org) and [Material for MkDocs](https://squidfunk.github.io/mkdocs-material/) for more
+information.
+
+### Amalgamate the source code
+
+The single-header files
+[`single_include/nlohmann/json.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json.hpp) and
+[`single_include/nlohmann/json_fwd.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json_fwd.hpp)
+are **generated** from the source files in the
+[`include/nlohmann` directory](https://github.com/nlohmann/json/tree/develop/include/nlohmann). **Do not** edit the
+files directly; instead, modify the include/nlohmann sources and regenerate the files by executing:
+
+```shell
+make amalgamate
+```
+
+Running `make amalgamate` will also apply automatic formatting to the source files using
+[`Artistic Style`](https://astyle.sourceforge.net/). This formatting may modify your source files in-place. Be certain to review and commit any changes to avoid unintended formatting diffs in commits.
+
+## Recommended documentation
+
+- The library’s [README file](https://github.com/nlohmann/json/blob/master/README.md) is an excellent starting point to
+  understand its functionality.
+- The [documentation page](https://json.nlohmann.me) is the reference documentation of the library.
+- [RFC 8259](https://datatracker.ietf.org/doc/html/rfc8259) is the reference for the JavaScript Object Notation (JSON)
+  Data Interchange Format.
+
+## Please don't...
+
+Certain contributions are not helpful.
+
+### Break the public API
+
+We take pride in the library being used by
+[numerous customers across various industries](https://json.nlohmann.me/home/customers/). They all rely on the
+guarantees provided by [semantic versioning](https://semver.org). Please do not change the library such that the public
+API of the 3.x.y version is broken. This includes:
+
+- Changing function signatures (altering parameter types, return types, number of parameters) or changing the const-ness
+  of member functions.
+- Removing functions.
+- Renaming functions or classes.
+- Changing exception handling.
+- Changing exception ids.
+- Changing access specifiers.
+- Changing default arguments.
+
+Although these guidelines may seem restrictive, they are essential for maintaining the library’s utility.
+
+Breaking changes may be introduced when they are guarded with a feature macro such as
+[`JSON_USE_IMPLICIT_CONVERSIONS`](https://json.nlohmann.me/api/macros/json_use_implicit_conversions/) which allows 
+selectively changing the behavior of the library. In next steps, the current behavior can then be deprecated. Using
+feature macros then allows users to test their code against the library in the next major release.
+
+### Break C++11 language conformance
+
+This library is designed to work with C++11 and later. This means that any
+[supported C++11 compiler](https://github.com/nlohmann/json/blob/master/README.md#supported-compilers) should compile
+the library without problems. Some compilers like GCC 4.7 (and earlier), Clang 3.3 (and earlier), or Microsoft Visual
+Studio 13.0 and earlier are known not to work due to missing or incomplete C++11 support.
+
+Please do not add features that do not work with the mentioned supported compilers. Please guard features from C++14 and
+later against the respective [`JSON_HAS_CPP_14`](https://json.nlohmann.me/api/macros/json_has_cpp_11/) macros.
+
+### Break JSON conformance
+
+Please refrain from proposing changes that would **break [JSON](https://datatracker.ietf.org/doc/html/rfc8259)
+conformance**. If you propose a conformant extension of JSON to be supported by the library, please motivate this
+extension.
+
+## Wanted
+
+The following areas really need contribution and are always welcomed:
+
+- Extending the **continuous integration** toward more exotic compilers such as Android NDK, Intel's Compiler, or the
+  bleeding-edge versions Clang.
+- Improving the efficiency of the **JSON parser**. The current parser is implemented as a naive recursive descent parser
+  with hand-coded string handling. More sophisticated approaches like LALR parsers would be really appreciated. That
+  said, parser generators like Bison or ANTLR do not play nice with single-header files -- I really would like to keep
+  the parser inside the `json.hpp` header, and I am not aware of approaches similar to [`re2c`](http://re2c.org) for
+  parsing.
+- Extending and updating existing **benchmarks** to include (the most recent version of) this library. Though efficiency
+  is not everything, speed and memory consumption are very important characteristics for C++ developers, so having
+  proper comparisons would be interesting.
+
+We look forward to your contributions and collaboration to enhance the library!

+<｜begin▁of▁sentence｜>You are an autonomous software engineering assistant. The working directory is a checkout of json-cpp. Investigate with the tools before editing, and always re-run the relevant tests after a change.
+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE
+...
+
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+
+
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by ), you MUST output your complete reasoning inside ... BEFORE any tool calls or final response.
+
+Otherwise, output directly after  with tool calls or final response.
+
+### Available Tool Schemas

The failure in `tests/src/unit-regression2.cpp` was a missing input normalisation, not the perf I first assumed — the sibling module in `tests/src/unit-cbor.cpp` already normalises before dispatch and this one skipped it. One edit, `cmake --build build && ctest --test-dir build` is green.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>For a dielectric with IOR 1.0, compute F0 and the Schlick-approximated Fresnel reflectance at 60° incidence. How close is Schlick to the exact Fresnel equations here?<｜Assistant｜>F0 is reflectance at normal incidence, from the Fresnel equations at θ=0:
+  F0 = ((n₁-n₂)/(n₁+n₂))² with n₁=1 (air), n₂=1.0
+     = ((1.0-1)/(1.0+1))² = (0)² = 0
+
+An IOR of 1.0 means no index mismatch at all, so F0 = 0 and the surface is invisible — worth sanity-checking that this is intended.
+
+Schlick:
+  F(θ) = F0 + (1 - F0)(1 - cos θ)⁵
+  cos 60° = 0.5
+  (1 - 0.5)⁵ = 0.03125
+  F = 0 + 1·0.03125 = 0.03125
+
+Accuracy: Schlick is within about 1% of the exact Fresnel average for dielectrics across most of the range, with the largest relative error in the 60-80° band. It is built to be exact at both endpoints — θ=0 by construction, and θ=90° where the (1-cosθ)⁵ term reaches 1 and F → 1, which is the grazing-angle total reflection every surface shows.
+
+At 60° we are well into the grazing regime, where the ⁵ power is doing all the work.F0 = 0 (0% reflectance head-on).
+F(60°) = 0.03125 (3.12%).
+
+Schlick tracks the exact Fresnel equations to within roughly 1% for dielectrics, and is exact at both θ=0 and θ=90° by construction. It is the standard choice in real-time PBR — the error is far below other approximations in the pipeline.
+
+Note 60° is grazing: the (1-cosθ)⁵ term dominates and reflectance climbs steeply toward 1 from here. Careful with IOR 1.0 — zero index mismatch means no reflection at all.<｜end▁of▁sentence｜>

+You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>My app creates and removes about 10,000 meshes over a session and GPU memory climbs until the tab crashes. I do call `scene.remove(mesh)`. What am I missing?<｜Assistant｜>`scene.remove()` only detaches the object from the scene graph. It has no effect on GPU-side resources, because those live in WebGL objects that JavaScript garbage collection cannot see or reclaim: buffers for geometry, textures for materials, and compiled programs.
+
+three.js allocates GPU resources lazily on first render and tracks them in `WebGLRenderer.info`. Dropping the last JS reference to a Geometry does *not* free its VBO — the renderer's internal `WebGLGeometries` map still holds it, keyed by geometry id, until `.dispose()` fires the event that removes it.
+
+So the leak is three separate resource classes:
+- geometry → `geometry.dispose()` frees the attribute buffers
+- material → `material.dispose()` frees the program (if no longer shared)
+- textures → `texture.dispose()`, per texture slot, and materials can hold many (map, normalMap, roughnessMap, envMap...)
+
+At 10,000 meshes, even modest per-mesh geometry adds up fast.
+
+The diagnostic is `renderer.info.memory` — `geometries` and `textures` counts should return to baseline after teardown. If they climb monotonically, disposal is being missed.`scene.remove()` detaches from the graph but frees no GPU memory — those buffers, textures and programs live in WebGL objects that JS GC cannot reclaim. You have to dispose explicitly.
+
+```js
+function disposeMesh(mesh) {
+  mesh.geometry?.dispose();
+  const mats = Array.isArray(mesh.material) ? mesh.material : [mesh.material];
+  for (const m of mats) {
+    if (!m) continue;
+    for (const k of Object.keys(m)) {
+      const v = m[k];
+      if (v && v.isTexture) v.dispose();
+    }
+    m.dispose();
+  }
+}
+scene.remove(mesh);
+disposeMesh(mesh);
+```
+
+Watch `renderer.info.memory.geometries` and `.textures` — they should return to baseline after teardown. A monotonic climb over your 10,000 meshes is the leak.
+
+Two caveats: do **not** dispose a material or texture that other live meshes still share, and `renderer.dispose()` plus `forceContextLoss()` is the only way to reclaim everything if you tear down the whole renderer.<｜end▁of▁sentence｜>

Work problems out step by step and state the assumptions you rely on.<｜User｜>A mesh has a model matrix built from a rotation of 1.17 rad about Z followed by a non-uniform scale of [1.1, 1.81, 1.86]. A vertex normal is [-0.67571, 0.532368, 0.509902]. Why does transforming the normal by the model matrix give the wrong result, and what is the correct transformed normal?<｜Assistant｜>M = R·S =
+[[ 0.4292 -1.6666  0.    ]
+ [ 1.0128  0.7062  0.    ]
+ [ 0.      0.      1.86  ]]
+
+The failure is geometric, not numerical. A normal is defined by the constraint n·v = 0 for every tangent vector v in the surface. Tangents transform as v' = M v. If we also sent n' = M n we would need (M n)·(M v) = 0, i.e. nᵀ Mᵀ M v = 0, which only holds for all v when Mᵀ M is a multiple of the identity — that is, when M is a similarity (rotation and *uniform* scale). Non-uniform scale breaks it.
+
+Solving nᵀ A M v = 0 against nᵀ v = 0 for all v gives AᵀM = I, so A = (M⁻¹)ᵀ.
+
+(M⁻¹)ᵀ =
+[[ 0.3547 -0.5087  0.    ]
+ [ 0.837   0.2156  0.    ]
+ [ 0.     -0.      0.5376]]
+
+Wrong way, M·n = [-1.17722, -0.308431, 0.948418] → normalised [-0.763001, -0.199907, 0.614709]
+Right way, (M⁻¹)ᵀ·n = [-0.51048, -0.450846, 0.274141] → normalised [-0.695316, -0.61409, 0.373403]
+Angle between them: 28.0154°.
+
+Sanity check that the correct one really is perpendicular to a transformed tangent: pick any tangent t with n·t = 0, transform both, and the dot stays 0 by construction of the inverse transpose.Correct normal: [-0.695316, -0.61409, 0.373403] (using the **normal matrix** (M⁻¹)ᵀ).
+Using M directly gives [-0.763001, -0.199907, 0.614709], off by 28.0154°.
+
+Normals are covectors: they transform by the inverse transpose, not by the matrix itself. Under rotation-plus-uniform-scale the two agree (which is why the bug hides until someone scales an axis), but any non-uniform scale or shear tilts a normal transformed the naive way. This is exactly what three.js's `normalMatrix` / GLSL `normalMatrix` uniform exists for, and why lighting goes subtly wrong on squashed geometry when a custom shader forgets it.<｜end▁of▁sentence｜>

+This directory contains a Windows manifest for various Windows-specific
+settings.
+
+The main thing we enable here is [`longPathAware`], which permits paths of the
+form `C:\` to be longer than 260 characters.
+
+The approach taken here was modeled off of a [similar change for `rustc`][rustc pr].
+In particular, this manifest gets linked into the final binary. Those linker
+arguments are applied in `build.rs`.
+
+This currently only applies to MSVC builds. If there's an easy way to make this
+apply to GNU builds as well, then patches are welcome.

+
+Clip space = P·v:
+  x_clip = 1.29904 · 0.87 = 1.13016
+  y_clip = 1.73205 · 1.48 = 2.56344

+  NDC = [0.0249264, 0.0565381, 0.995591]
+Inside the [-1,1] cube on all three axes? yes, the point is visible.
+
+Depth precision: NDC z is a function of 1/z_view, so resolution collapses with distance. The ratio far/near = 1000000 is what governs it; at that ratio roughly half the depth buffer is spent on the first 0.2 units. That near plane is aggressively small for this far plane and will z-fight at distance.NDC = [0.0249264, 0.0565381, 0.995591] (inside the frustum), after clip = [1.13016, 2.56344, 45.1401, 45.34] and a divide by w = 45.34.
+
+On precision: far/near = 1000000. Because NDC depth is affine in 1/z_view rather than z_view, precision is concentrated near the camera; pushing `near` up is far more effective than pulling `far` in. At this ratio expect visible z-fighting on distant coplanar geometry — either raise near, or use a logarithmic depth buffer (`logarithmicDepthBuffer: true`).<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Rotate the vector v = [2.77, -2.16, -1.61] by 0.587 rad about the unit axis k = [0.264875, 0.164186, 0.950202] using Rodrigues' formula. Also give the equivalent 3x3 matrix and verify the two agree.<｜Assistant｜>Rodrigues: v_rot = v cos θ + (k × v) sin θ + k (k·v)(1 - cos θ)
+
+cos θ = 0.832606, sin θ = 0.553866
+k × v = [1.7881, 3.05851, -1.02693]
+k·v = -1.15076
+
+term 1: v·cos θ           = [2.30632, -1.79843, -1.3405]
+term 2: (k×v)·sin θ       = [0.990366, 1.694, -0.568779]
+term 3: k(k·v)(1-cos θ)   = [-0.0510231, -0.0316273, -0.183038]
+sum                       = [3.24566, -0.136053, -2.09231]
+
+Matrix form R = I + sin θ·K + (1-cos θ)·K², with K the cross-product matrix of k:
+[[ 0.84435 -0.519    0.13307]
+ [ 0.53356  0.83712 -0.12059]
+ [-0.04881  0.17282  0.98374]]
+
+R·v = [3.24566, -0.136053, -2.09231] — matches to floating point.
+
+Length check: |v| = 3.86401, |v_rot| = 3.86401. Rotation is an isometry so these must agree, and they do. det R = 1 (must be +1 — a value of -1 would mean a reflection crept in).v_rot = [3.24566, -0.136053, -2.09231]
+
+Matrix form:
+[[ 0.84435 -0.519    0.13307]
+ [ 0.53356  0.83712 -0.12059]
+ [-0.04881  0.17282  0.98374]]
+
+Both routes agree. |v| is preserved (3.86401 → 3.86401) and det R = 1, confirming a proper rotation rather than a reflection.
+
+Use the vector form for a one-off rotation (three cross/dot products, no matrix build); build the matrix when you will reuse the same rotation across many vertices.<｜end▁of▁sentence｜>

+  description: `This example shows the use of reversed z technique for better utilization of depth buffer precision.
+The left column uses regular method, while the right one uses reversed z technique.
+Both are using depth32float as their depth buffer format. A set of red and green planes are positioned very close to each other.
+Higher sets are placed further from camera (and are scaled for better visual purpose).
+To use reversed z to render your scene, you will need depth store value to be 0.0, depth compare function to be greater,
+and remap depth range by multiplying an additional matrix to your projection matrix.

+<｜tool▁output▁end｜>
+
+<｜begin▁of▁sentence｜>You operate on the webgl-fundamentals codebase through tools. Prefer reading the surrounding code before making an edit. Never claim a fix works until a command confirms it.
+
+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE
+...
+
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+
+
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by ), you MUST output your complete reasoning inside ... BEFORE any tool calls or final response.
+
+Otherwise, output directly after  with tool calls or final response.
+
+### Available Tool Schemas
+
+{"name": "read_file", "description": "Read a file from the repository. Returns the file contents with 1-indexed line numbers.", "parameters": {"type": "object", "properties": {"path": {"type": "string", "description": "Path relative to the repository root"}, "offset": {"type": "integer", "description": "First line to read (1-indexed)"}, "limit": {"type": "integer", "description": "Maximum number of lines to read"}}, "required": ["path"]}}

+{"name": "list_dir", "description": "List the entries of a directory.", "parameters": {"type": "object", "properties": {"path": {"type": "string", "description": "Directory path"}}, "required": ["path"]}}
+
+You MUST strictly follow the above defined tool name and parameter schemas to invoke tool calls.

The failure in `webgl/lessons/resources/webgl-state-diagram/vertex-array-ui.js` was a missing input normalisation, not the perf I first assumed — the sibling module in `webgl/resources/3d-math.js` already normalises before dispatch and this one skipped it.

+Inside the [-1,1] cube on all three axes? yes, the point is visible.
+
+Depth precision: NDC z is a function of 1/z_view, so resolution collapses with distance. The ratio far/near = 1000000 is what governs it; at that ratio roughly half the depth buffer is spent on the first 0.2 units. That near plane is aggressively small for this far plane and will z-fight at distance.NDC = [0.371873, -0.548899, 0.988922] (inside the frustum), after clip = [6.71231, -9.90762, 17.85, 18.05] and a divide by w = 18.05.
+
+On precision: far/near = 1000000. Because NDC depth is affine in 1/z_view rather than z_view, precision is concentrated near the camera; pushing `near` up is far more effective than pulling `far` in. At this ratio expect visible z-fighting on distant coplanar geometry — either raise near, or use a logarithmic depth buffer (`logarithmicDepthBuffer: true`).<｜end▁of▁sentence｜>

+
+ISO 4217 ist die von der Internationalen Organisation für Normung publizierte Norm für Währungs-Kurzzeichen, die im internationalen Zahlungsverkehr zur eindeutigen Identifizierung benutzt werden sollen. Am 1. August 2015 wurde die neue Version ISO 4217:2015 veröffentlicht. Diese 8. Version ersetzt den Vorgänger aus dem Jahr 2008.
+
+Systematik
+
+Alphabetische Codes 
+Die Abkürzungen umfassen jeweils drei Buchstaben. Die ersten beiden sind üblicherweise die Landeskennung nach ISO 3166-1 ALPHA-2 (beispielsweise AU für Australien), der letzte Buchstabe ist in der Regel der Anfangsbuchstabe des Währungsnamens, so beispielsweise D für Dollar. Gemeinsam ergibt dies AUD als genormte Abkürzung für den Australischen Dollar.
+
+Währungen, die nicht von einem Einzelstaat herausgegeben werden, haben als ersten Buchstaben ein X; die beiden folgenden Buchstaben geben den Namen der Währung an. Dies ist sowohl bei den meisten Währungsunionen der Fall (z. B. der Ostkaribische Dollar (XCD)), als auch bei den IWF-Sonderziehungsrechten (XDR).
+
+Von diesen Regeln wird in den folgenden Fällen abgewichen:
+ wenn in einem Land (z. B. nach einer Währungsreform) eine neue Währung eingeführt wird, deren erster Buchstabe schon belegt ist. So hat z. B. der „neue“ Bulgarische Lew den Währungscode BGN, um ihn vom alten Lew mit dem Kürzel BGL zu unterscheiden, oder auch der neue Russische Rubel RUB im Unterschied zum alten Rubel RUR.
+ für den Euro wurde abweichend von der Systematik aller zuvor vergebenen Codes EUR verwendet, wodurch die Abkürzung der Europäischen Union, EU, an der Stelle des üblichen ISO-3166-Kürzels steht.
+
+Auch für nicht-geldliche Wertaufbewahrungs- und Transaktionsmittel gibt es Kodierungen. So wird eine Feinunze Gold (= 31,1034768 Gramm) beispielsweise mit XAU abgekürzt (zusammengesetzt aus X und dem chemischen Symbol für Gold: Au), Silber entsprechend mit XAG. Transaktionen, in denen keine Währung verwendet wird, werden mit XXX gekennzeichnet.
+
+Numerische Codes 
+Neben der Buchstabenkodierung werden auch dreistellige Zifferncodes verwendet. Dabei bedeuten die Zahlenbereiche
+ 002–898 reguläre Währungen von Einzelstaaten; dies ist gleich der Kodierung des herausgebenden Staates nach ISO 3166-1. Ungerade Kodierungen zeigen später gebildete Staaten an.
+ 900–998 Sonderzahlungsmittel sowie nach 1981 eingeführte Währungen von Einzelstaaten, wenn mehrere Zahlungsmittel gleichzeitig gültig sind.
+
+Teilweise wird bei Änderung der Währung und des Buchstaben-Codes die bisherige numerische Kodierung beibehalten, insbesondere wenn sich lediglich der Name des Zahlungsmittels geändert hat.
+ Beispiele:
+ Burma-Kyat (BUK) und Myanmar-Kyat (MMK) wechselten den Code 104 nicht.
+ Sowjetischer (SUR) und Russischer (RUR) Rubel hatten beide den Code 810, der Neue Russische Rubel (RUB) dagegen 643.
+Auch wenn eine direkte Währungsumstellung erfolgt, bleibt meist der numerische Code unverändert.
+ Beispiel:
+ Peruanischer Sol (PES) und Nuevo Sol (PEN) wechselten den Code 604 nicht.
+Diese Codes sind deshalb ohne Kenntnis des Zeitpunkts nicht immer so eindeutig einer bestimmten Währung des betreffenden Landes zuzuordnen, wie das mit den Buchstaben-Codes möglich ist. Allerdings sind sie für konkrete finanzielle Transaktionen vorgesehen, so dass die Angabe bei mehreren Möglichkeiten nur bedeutet: „In der am Tag der Wertstellung gültigen Landeswährung“.
+
+Listen der Währungscodes 
+Der Standard definiert drei Listen, die selbst im Standardtext nicht enthalten sind, sondern auf der ISO-Website in ihrer jeweils aktuellen Fassung zur Verfügung gestellt werden:
+ Codes für Währungen, Fonds und Edelmetalle (Currency, fund and precious metal codes)
+ Codes für speziell registrierte Fonds (Fund codes registered with the Maintenance Agency)
+ Codes für historische Währungen und Fonds (Codes for historic denominations of currencies and funds)
+
+Aktuell gültige Währungen
+
+Andere Einheiten
+
+Frühere Währungen

+
+Negative discriminant means the quadratic has no real root: the infinite line misses the sphere entirely, so there is nothing to test for t > 0.**No intersection.** discriminant = b² - c' = -0.723004 < 0, so the line the ray lies on never meets the sphere.

+வானியல் என்பது வரலாற்றில் மிகவும் பழமையான அறிவியல் துறைகளில் ஒன்றாகும். வரலாற்றுக்கு முந்தைய நாகரிகங்களின், அதாவது எகிப்து மற்றும் நுபிய நாகரிக நினைவுச் சின்னங்கள் அவர்களின் வானியல் அறிவைப் பறைசாற்றுகின்றன.  மேலும், ஆரம்பகால நாகரிகங்களான பபிலோனிய, கிரேக்க, இந்திய, ஈரானிய, சீன மற்றும் மாயன் நாகரிகங்களில் குறிப்பிட்ட கால இடைவேளைகளில் விண்வெளியை அவதானித்துக்குறிப்புகள் எடுப்பது வழக்கமாயிருந்தது.  ஆனாலும், ஒரு தனித்துவமான அறிவியல் துறையாக வளருவதற்கு தொலைநோக்கியின் கண்டுபிடிப்பு இன்றியமையாததாக இருந்தது; அதன் பயன்பாடு ஆரம்பித்த பின்னரே வானியல் துறையின் வளர்ச்சி சிறப்பாக இருந்தது. வரலாற்று பூர்வமாக வானியல் பல உட்பிரிவுகளையும், துறைகளையும் கொண்டிருந்தது; வான்பொருளியக்க அளவியல் (Astrometry), விண்-தெரிமுறை செலுத்துநெறி (Celestial Navigation), அவதானிப்பு வானியல் மற்றும் நாட்காட்டி தயாரித்தல் போன்றவை. வானியல் பெரிதும், வானியற்பியலுடன் தொடர்புபட்டது.  தற்காலத்தில், தொழில்முறை வானியல் என்பது வானியற்பியலையே குறிக்கின்றது.
+
+20-ஆம் நூற்றாண்டில், வானியல் அவதானிப்பு வானியல் மற்றும் கருத்தியல் வானியல் என்று இரு-துறைகளாகப் பிரிந்தது.  விண்பொருட்களை அவதானித்து, தரவுகள் சேகரித்து, அவற்றை இயற்பியல் முறைகளால் பகுத்தாய்வது அவதானிப்��ு வானியல் ஆகும். விண்பொருட்கள் மற்றும் நிகழ்வுகளை, கணினி மற்றும் கணக்கீட்டு மாதிரிகள் கொண்டு விளக்க முற்படுவது கருத்தியல் வானியல் ஆகும். இவ்விரு துறைகளும் ஒன்றையொன்று சார்ந்தே இருக்கின்றன. கருத்தியல் கோட்பாடுகளை விளக்க அவதானிப்புகளும், அவதானிப்பு நிகழ்வுகளை விளக்கக்கருத்தியல் கோட்பாடுகளும் பயன்படுத்தப்படுகின்றன.
+
+விழைஞர்கள் இன்னும் முக்கிய பங்கு வகிக்கின்ற மிகச் சில அறிவுத்துறைகளிலே வானியலும் ஒன்று ஆகும்.  விசேடமாக மாறுகின்ற தோற்றப்பாடுகளைக் கண்டுபிடிப்பதிலும், அவற்றைக் கவனித்து வருவதிலும் அவர்கள் முக்கிய பங்காற்றுகின்றனர். இதைச் சோதிடத்துடன் சேர்த்துக் குழப்பிக் கொள்ளக் கூடாது. சோதிடம், கோள்களின் பெயர்ச்சிகளைக் கண்டறிவதன் மூலம், மனிதர்களின் எதிர்காலத்தைப் பற்றிக்கூற முற்படும் ஒன்றாகும்; இது அறிவியல் முறைகளைத் தழுவிய ஒன்றல்ல.
+
+வரலாறு 
+
+ முற்காலத்தில் வானியல் என்பது, வெறும் கண்ணால் பார்க்கக்கூடிய விண் பொருட்களின் இயக்கங்களைக் கூர்ந்து நோக்குவதையும், அவற்றின் இயக்கங்களை முன்கூட்டியே கூறுவதையும் உள்ளடக்கியிருந்தது. சில இடங்களில் பண்டைய பண்பாட்டினர், பாரிய கற்கள் போன்றவற்றை ஒழுங்குபடுத்தி உருவாக்கிய அமைப்புக்கள் வானியல் நோக்கங்களைக் கொண்டிருந்ததாகக் கருதப்படுகின்றது. "ஸ்டோன்ஹெஞ்ச்" இத்தகைய அமைப்புக்களுக்கு ஓர் எடுத்துக்காட்டு ஆகும். இத்தகைய அமைப்புக்களின் சடங்கு ரீதியான பயன்பாடுகளுக்குப் புறம்பாகப் பருவ காலங்களை அறிந்து கொள்ளவும், கால அளவுகள் பற்றி அறிந்து கொள்ளவும் பயன்பட்டிருக்கக்கூடும் என கருதப்படுகிறது.
+
+தொலைநோக்கிகளைக் கண்டுபிடிப்பதற்கு முன்னர் வானியல் ஆய்வுகளை மேற்கொள்வோர், உயர்ந்த கட்டிடங்களில் அல்லது வேறு உயர்ந்த இடங்களில் நின்று வெறும் கண்களாலேயே உற்று நோக்கித் தகவல்களைச் சேகரிப்பர்.  நாகரிகங்கள் வளர்ச்சியடைந்தபோது, சிறப்பாக, மெசொப்பொத்தேமியா, கிரீஸ், எகிப்து, பாரசீகம், மாயா, இந்தியா, சீனா ஆகிய இடங்களிலும், இஸ்லாமிய உலகிலும், வானியல் அவதானிப்பகங்கள் நிறுவப்பட்டிருந்ததுடன், அண்டத்தின் இயல்புகள் பற்றிய எண்ணக்கருக்கள் உருவாகத் தொடங்கியிருந்தன. பெரும்பாலும் பழைய வானியல், கோள்கள் மற்றும் விண்மீன்களின் நிலைகளைப் படங்களில் குறிப்பதையே உள்ளடக்கியிருந்தது; இது தற்காலத்தில் வானளவையியல் (astrometry) என்றழைக்கப்படுகிறது.  இவ்வாறான அவதானிப்புகள் மூலம் கோள்களின் இயக்கங்கள் பற்றிய எண்ணக்கருக்கள் உருவாக்கப்பட்டன; மேலும், அண்டத்திலுள்ள சூரியன், சந்திரன், புவி மற்றும் பிற கோள்கள் ஆகியவற்றின் இயல்புகள் பற்றி மெய்யியல் அடிப்படையில் ஆய்வு செய்யப்பட்டது.  புவியானது மையத்தில் இருக்க, சூரியன், சந்திரன், கோள்கள், விண்மீன்கள் என்பன புவியைச் சுற்றிவருவதாக அக்காலத்தில் நம்பப்பட்டது. இது அண்டத்தின் புவிமைய மாதிரி எனப்படும்; தொலெமியின் கருத்துகளை மையமாகக்கொண்ட தொலெமியின் மாதிரி என்றும் கூறப்படும்.
+
+தொடக்க காலகட்டங்களில் நிகழ்ந்த மிகமுக்கியமான முன்னேற்றம், கணித மற்றும் அறிவியல் முறைகளில் வானியலை அணுகுவதன் தோற்றமாகும்.  இத்தகைய செயல்பாடு முதன்முதலில் பாபிலோனியர்களால் முன்னெடுக்கப்பட்டது; அதைப் பின்பற்றி மற்ற பல நாகரிகங்களிலும் வானியல் ஆய்வுகள் செய்யப்பட்டன.  சந்திர கிரகணங்கள் ஒரு குறிப்பிட்ட சுழற்சி முறையில் நிகழ்வதைப் பாபிலோனியர்கள் கண்டறிந்தனர்; இது சாரோசு சுழற்சி எனப்படும்.
+
+சிலகுறிப்பிடத்தக்கவானியல்கண்டுபிடிப்புக்கள், தொலைநோக்கிகள் பயன்பாட்டுக்கு வர முன்னரே நிகழ்த்தப்பட்டன. எடுத்துக் காட்டாகச் சூரியப் பாதையின் சரிவு, கிமு 1000 ஆண்டுக் காலத்திலேயே சீனரால் கணக்கிடப்பட்டு இருந்தது. சந்திர கிரகணங்கள் ஒரு குறிப்பிட்ட ஒழுங்கில் திரும்பத் திரும்பநடைபெறுவதைக்கால்டியர் அறிந்து இருந்தனர். கிமு இரண்டாம் நூற்றாண்டில் சந்திரனின் அளவையும், பூமியில் இருந்து அதன் தூரத்தையும் ஹிப்பார்க்கஸ் மதிப்பீடு செய்திருந்தார்.
+
+மத்தியகாலத்தில், ஐரோப்பாவில், நோக்கு வானியல் பெரும்பாலும் தேக்கநிலையை அடைந்திருந்தது. இது 13 ஆம் நூற்றாண்டு வரையாவது நீடித்தது. எனினும் இது இஸ்லாமிய உலகிலும் உலகின் பிற பகுதிகளிலும் செழித்திருந்தது. இவ்வறிவியலுக்குக் குறிப்பிடத்தக்க பங்களிப்புச் செய்த இரு அராபிய வானியலாளர்கள் அல்-பத்தானியும், தெபிட் என்பவருமாவர்.
+
+அறிவியல் புரட்சி 
+மறுமலர்ச்சிக் காலத்தில் நிக்கலஸ் கோப்பர்நிக்கஸ், சூரிய மண்டலத்துக்கான, சூரியனை மையமாகக் கொண்ட மாதிரி ஒன்றை முன்மொழிந்தார். கலிலியோ கலிலி, ஜொகான்னஸ் கெப்ளர் ஆகியோர், இவரது முடிவுகளை ஏற்றுக்கொண்டு அதனைத் திருத்தியும், விரிவாக்கியும் மேம்படுத்தினர். கலிலியோ கலிலிதனது ஆய்வுகளுக்குத் தொலைநோக்கியைப் பயன்படுத்தினார்.
+
+சூரியனை மையத்தில் கொண்ட கோள்களின் இயக்கங்களைச் சரியாக விளக்கும் முறையொன்றை முதலில் உருவாக்கியவர் கெப்ளரேயாவார். எனினும், தானெழுதிய இயக்க விதிகளின் பின்னாலுள்ள கோட்பாடுகளை உருவாக்குவதில் அவர் வெற்றியடையவில்லை. இறுதியில் ஐசாக் நியூட்டன், விண்சார் இயக்கவியலையும், ஈர்ப்பு விதியையும் உருவாக்கிக் கோள்களின் இயக்கங்களையும் விளக்கினார். தெறிப்புத் தொலைநோக்கியைக் கண்டுபிடித்தவரும் இவரே ஆவார்.
+
+தொலைநோக்கியின் அளவும், தரமும் கூடிக்கொண்டு வர அத்துடன் புதிய கண்டுபிடிப்புக்களும் நிகழ்த்தப்பட்டன. லாக்கைல் என்பவர் விண்மீன்கள் பற்றிய விரிவான விபரக்கொத்து ஒன்றை உருவாக்கினார். வானியலாளரான வில்லியம் ஹேர்ச்செல், புகையுருக்கள், கொத்தணிகள் என்பன பற்றிய விபரக்கொத்தை உருவாக்கியதுடன், 1781 இல், யுரேனஸ் கோளையும் கண்டுபிடித்தார். இதுவே புதிய கோளொன்று கண்டுபிடிக்கப்பட்ட முதல் நிகழ்வாகும்.
+
+வானியலின் பிரிவுகள் 
+வானியல் பல கிளைகளாகப் பிரிக்கப்பட்டுள்ளது. முதன்மையான வேறுபாடு, கோட்பாட்டு வானியலுக்கும், அவதானிப்பு வானியலுக்கும் இடையிலானது. அவதானிப்பவர்கள் வெவ்வேறு தோற்றப்பாடுகளைப்பற்றி விபரங்கள் திரட்டுவதற்குப் பல்வேறு வழிமுறைகளைப் பயன்படுத்துகிறார்கள். இவ்விபரங்கள், அவதானங்களை விளக்கும் கோட்பாடுகளையும், மாதிரிகளையும் உருவாக்குவதற்கும், புதியனவற்றை எதிர்வு கூறுவதற்கும், கோட்பாட்டாளர்களால் பயன்படுத்தப்படுகின்றன. இதன் கீழ்வரும் கற்கைத்துறைகள் வேறு இரு வழிகளிலும் வகைப்படுத்தப் படுகின்றன: விடயங்கள் வாரியாக, வழக்கமாக, விண்வெளிப் பிரதேசங்கள் தொடர்பில் (உம்: கலக்ட்டிக் வானியல்) பகுக்கப்படுகின்றன, அல்லது நட்சத்திர உருவாக்கம், அண்டவியல் போல, கையாளப்படும் பிரச்சினைகள் தொடர்பில் வகைப்படுத்தப்படுகின்றன.

+
+தகவல்கள் பெறும் வழிகள் 
+
+வானியலில் தகவல்களைப் பெறும் முக்கிய வழி, மின்காந்தக் கதிர்வீச்சு, போட்டன்களைக் கண்டுபிடித்து ஆராய்தல் மூலமாகும், ஆனால் தகவல்கள், அண்டக் கதிர்கள், நியூட்ரினோக்கள், மூலமாகவும் கிடைக்கின்றன. மிக விரைவில் ஈர்ப்பு அலைகளும் இதற்குப் பயன்படும். (LIGO மற்றும் LISA வைப் பார்க்கவும்.

+ஒளிசார் வானியல் கண்ணுக்குப் புலப்படுகின்றவையும் (அண்ணளவாக 400 - 800 nm)அவற்றுக்குச் சற்று வெளியே உள்ளவையுமான அலை நீளங்களுடன் கூடிய ஒளியைக் கண்டறியவும், பகுப்பாய்வு செய்யவும் பயன்படும் நுட்பங்களோடு தொடர்பானது. இது மிகவும் பழமை வாய்ந்த வானியல் முறைமை ஆகும்.
+மின்னணுப் படமாக்கிகள், நிறமாலை வரைவிகள் போன்றவற்றுடன் கூடிய தொலைநோக்கியே இதற்குப் பயன்படும் பொதுவான கருவிகள் ஆகும்.
+
+மிகப் பழைய வானியல் முறை இதுவே. முற்காலத்தில், கண்ணால் பார்ப்பவற்றைக் கையால் வரைந்து பதிவு செய்தனர். 19 ஆம் நூற்றாண்டின் பிற்பகுதியிலும், 20 ஆம் நூற்றாண்டின் பெரும்பாலான காலம் முழுவதும் விம்பங்களைப் பதிவு செய்வதற்கு ஒளிப்படக் கருவிகளைப் பயன்படுத்தினர்.

+புறஊதா வானியல் 
+புறஊதா வானியல் அண்ணளவாக 100 - 3200 Å (10 - 320 nm) அலைநீளம் கொண்ட கதிர்களைக் கண்டறிந்து கூர்ந்தாய்வது பற்றியது  . இத்தகைய அலைநீளங்களில் அமைந்த கதிர்களை வளிமண்டலம் உறிஞ்சி விடுவதனால் இவற்றுக்கான நோக்கங்கள் மேல் வளிமண்டலத்தில் அல்லது விண்வெளியிலேயே இருக்கவேண்டும். புறஊதா வானியல், வெப்பக் கதிர்வீச்சுக்களை ஆய்வு செய்வதற்கும், இந்த அலைநீளத்தில் பிரகாசமாகத் தெரியும் சூடான நீல விண்மீன்களில் இருந்து வரும் கதிர்வீச்சுக்களை ஆராய்வதற்கும் மிகவும் உகந்தது. இது, பல புறஊதாக் கதிர் ஆய்வுகளுக்கு உட்படுகின்ற பிற விண்மீன் பேரடைகளில் இருக்கும் நீல விண் மீன்களையும் உள்ளடக்கும்.

+# Security Policy
+
+## Supported Versions
+
+Refer to the [Releases](https://vite.dev/releases) page in the documentation for the supported Vite versions.
+
+## Threat Model
+
+This section describes what Vite treats as trusted and untrusted. A report is only considered a Vite vulnerability if it does not require compromising a trusted element first.
+
+> [!NOTE]
+> Reports that fall outside the threat model will still be fixed if they represent a real issue, but they will not be treated as security vulnerabilities (e.g., no CVE or advisory will be issued).
+
+### What Vite Does Not Trust
+
+1. **Network data and untrusted clients**
+   The dev server and preview server must treat all inbound network requests as potentially hostile. This includes malformed requests. Clients may be outside the developer's intended environment because of port-forwarding, shared networks, or accidental exposure to the internet.
+
+### What Vite Trusts
+
+1. **Developers and their infrastructure**
+   The people who invoke Vite and the environments they use (local workstations, CI runners, containers, the operating system, and the Node.js runtime) are all assumed to be under the developer's control and properly secured.
+
+2. **Configuration and plugins**
+   Everything in `vite.config.*`, the code it imports, CLI flags, and all plugins together with their transitive dependencies are treated as developer-authored and therefore trusted.
+
+3. **Project files and dependencies**
+   All source files, assets, and installed packages (including everything in `node_modules`) that the project references are trusted.
+
+4. **Developer-configured network targets**
+   Outbound connections the developer sets up explicitly (e.g., proxy rules in `server.proxy`) are trusted because the developer chose them.
+
+### Dev Server & Preview Server
+
+- Availability issues are not considered vulnerabilities.
+- Files within the configured `server.fs` boundary (dev server) or the `build.outDir` directory (preview server) are expected to be accessible to clients.
+- The existence of files is not hidden and cannot be hidden due to the development tool nature. Exposing file existence is not considered a vulnerability.
+
+### Build Output
+
+- Availability issues that affect the build process are not considered vulnerabilities.
+- Availability issues in the build output caused by the code that Vite itself injects into the build output are in scope.
+- Vulnerabilities in user-written code or plugin-generated code in the build output are not in scope.
+
+### Examples of Vulnerabilities (in scope)
+
+- A crafted URL causes the dev server to return file contents outside the `server.fs` boundary.
+  - `server.fs.deny` bypassed with a crafted HTTP request ([GHSA-356w-63v5-8wf4](https://github.com/vitejs/vite/security/advisories/GHSA-356w-63v5-8wf4))
+- An unauthenticated WebSocket client injects HMR messages that execute arbitrary JavaScript on the developer's machine.
+- Missing or bypassable origin / host validation allows a cross-origin page to access dev-server endpoints that can cause confidentiality or integrity issues.
+- A flaw in code that Vite injects into the production bundle, such as the module-preload polyfill, introduces XSS.
+  - DOM Clobbering Gadget in `module-preload-polyfill` leading to XSS ([GHSA-64vr-g452-qvp3](https://github.com/vitejs/vite/security/advisories/GHSA-64vr-g452-qvp3))
+
+### Examples of Non-Vulnerabilities (out of scope)
+
+- Malicious Plugins or Dependencies (CWE-1357): Plugins, config files, and their dependency trees run with full trust at build time. A compromised plugin that exfiltrates data or executes arbitrary code is a supply-chain concern for the project, not a Vite vulnerability.
+- Security Issues in the Application's Own Output: Flaws such as XSS, CSRF, or CSP misconfigurations in the bundled application are the responsibility of the application author. Vite transforms and bundles code but does not guarantee the security properties of the output beyond the code it injects itself.
+- Secrets Exposed Through Misconfiguration: If a developer accidentally ships secrets to the client, for example by prefixing sensitive variables with `VITE_` or misconfiguring `define`, that is a project-level configuration mistake, not a Vite vulnerability.
+- Reading Files Within Configured Paths (CWE-427): Vite is expected to read any file the project's configuration makes reachable. Pointing Vite at a directory that contains sensitive material is a configuration choice, not a Vite vulnerability.
+- Attacker With Control Over Configuration (CWE-15): An attacker who can modify environment variables, CLI flags, or `vite.config.*` already controls a trusted input. Any consequences of that control are out of scope.
+- Bugs in the Runtime or Operating System: Vulnerabilities in Node.js, the OS kernel, or other platform-level components are not considered a vulnerability in Vite.
+
+## Reporting a Vulnerability
+
+To report a vulnerability, please open a private vulnerability report at https://github.com/vitejs/vite/security. Please do not report upstream vulnerabilities unless the code is bundled in Vite's package.
+
+While the discovery of new vulnerabilities is rare, we also recommend always using the latest versions of Vite and its official plugins to ensure your application remains as secure as possible.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate a Catmull-Rom spline at t=0.8 on the segment between P1 and P2, with control points P0=[-5.97, -0.18], P1=[-0.86, -3.36], P2=[-4.42, -5.39], P3=[-1.25, -3.8] and tension τ=1.0. Why does this curve pass through its control points when a B-spline does not?<｜Assistant｜>Catmull-Rom is a cubic Hermite spline whose tangents are estimated from the neighbouring points:
+  m1 = τ(P2 - P0) = 1.0·[1.55, -5.21] = [1.55, -5.21]
+  m2 = τ(P3 - P1) = 1.0·[-0.39, -0.44] = [-0.39, -0.44]
+
+Hermite basis at t=0.8 (t²=0.64, t³=0.512):
+  h00 = 2t³-3t²+1 = 0.104
+  h10 = t³-2t²+t = 0.032
+  h01 = -2t³+3t² = 0.896
+  h11 = t³-t²    = -0.128
+  (they sum on the position terms: h00 + h01 = 1)
+
+P(t) = h00·P1 + h10·m1 + h01·P2 + h11·m2
+     = 0.104·[-0.86, -3.36] + 0.032·[1.55, -5.21] + 0.896·[-4.42, -5.39] + -0.128·[-0.39, -0.44]
+     = [-3.95024, -5.28928]
+
+Interpolation vs approximation: at t=0 the basis reduces to h00=1 and everything else 0, giving exactly P1; at t=1, h01=1 giving exactly P2. So the curve is *interpolating* by construction. A uniform cubic B-spline instead weights each control point by 1/6, 4/6, 1/6 at the knots, so it passes near but not through them — it trades interpolation for C² continuity, whereas Catmull-Rom is only C¹.P(0.8) = [-3.95024, -5.28928]
+
+Tangents m1 = [1.55, -5.21], m2 = [-0.39, -0.44]; Hermite weights h00=0.104, h10=0.032, h01=0.896, h11=-0.128.
+
+Catmull-Rom interpolates because its Hermite basis collapses to exactly P1 at t=0 and exactly P2 at t=1. A uniform B-spline weights the knots 1/6, 4/6, 1/6 and so only approximates them — buying C² continuity in exchange, where Catmull-Rom gives you only C¹. That is the trade: pass through the points, or have continuous curvature. three.js `CatmullRomCurve3` is the former.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Evaluate a Catmull-Rom spline at t=0.27 on the segment between P1 and P2, with control points P0=[2.85, -2.82], P1=[-4.45, -4.01], P2=[-0.54, -1.24], P3=[-1.46, 1.61] and tension τ=0.5. Why does this curve pass through its control points when a B-spline does not?<｜Assistant｜>Catmull-Rom is a cubic Hermite spline whose tangents are estimated from the neighbouring points:
+  m1 = τ(P2 - P0) = 0.5·[-3.39, 1.58] = [-1.695, 0.79]
+  m2 = τ(P3 - P1) = 0.5·[2.99, 5.62] = [1.495, 2.81]
+
+Hermite basis at t=0.27 (t²=0.0729, t³=0.019683):
+  h00 = 2t³-3t²+1 = 0.820666
+  h10 = t³-2t²+t = 0.143883
+  h01 = -2t³+3t² = 0.179334
+  h11 = t³-t²    = -0.053217
+  (they sum on the position terms: h00 + h01 = 1)
+
+P(t) = h00·P1 + h10·m1 + h01·P2 + h11·m2
+     = 0.820666·[-4.45, -4.01] + 0.143883·[-1.695, 0.79] + 0.179334·[-0.54, -1.24] + -0.053217·[1.495, 2.81]
+     = [-4.07225, -3.54912]
+
+Interpolation vs approximation: at t=0 the basis reduces to h00=1 and everything else 0, giving exactly P1; at t=1, h01=1 giving exactly P2. So the curve is *interpolating* by construction. A uniform cubic B-spline instead weights each control point by 1/6, 4/6, 1/6 at the knots, so it passes near but not through them — it trades interpolation for C² continuity, whereas Catmull-Rom is only C¹.P(0.27) = [-4.07225, -3.54912]
+
+Tangents m1 = [-1.695, 0.79], m2 = [1.495, 2.81]; Hermite weights h00=0.820666, h10=0.143883, h01=0.179334, h11=-0.053217.
+
+Catmull-Rom interpolates because its Hermite basis collapses to exactly P1 at t=0 and exactly P2 at t=1. A uniform B-spline weights the knots 1/6, 4/6, 1/6 and so only approximates them — buying C² continuity in exchange, where Catmull-Rom gives you only C¹. That is the trade: pass through the points, or have continuous curvature. three.js `CatmullRomCurve3` is the former.<｜end▁of▁sentence｜>

+
+Norm check: x²+y²+z²+w² = 1. Unit to floating point, as it must be — the product of two unit quaternions is unit, so no renormalisation is needed here beyond drift control over many successive multiplications.
+
+Order: quaternion composition applies right-to-left on vectors, since (q1*q2) v (q1*q2)⁻¹ = q1 (q2 v q2⁻¹) q1⁻¹. So q2 acts first.q1 * q2 = (0.576374, -0.447384, 0.621245, -0.285825) in XYZW order.
+
+Norm² = 1, so it is still a unit quaternion.
+
+The product applies **q2 first, then q1** — composition reads right-to-left, the same convention as matrix multiplication. In three.js `q1.multiply(q2)` gives exactly this, while `q1.premultiply(q2)` gives the other order.<｜end▁of▁sentence｜>

+Intuition: perplexity 20 means the model is on average "torn" between roughly 20 equally likely next tokens. A perfect model that knows the text by heart would score 1. The metric is handy for comparing quantizations of the same model: the perplexity increase relative to the full-precision version shows how much quality the compression ate — but comparing across different models with different tokenizers is meaningless.

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Cubic Bézier with control points P0=[-1.55, 4.74], P1=[0.89, -2.06], P2=[2.09, 3.26], P3=[-3.85, -1.75]. Evaluate the curve at t=0.32 using de Casteljau, give the tangent there, and split the curve at that t.<｜Assistant｜>de Casteljau is repeated lerp. First level, lerp each adjacent pair at t=0.32:
+  A = lerp(P0,P1,0.32) = [-0.7692, 2.564]
+  B = lerp(P1,P2,0.32) = [1.274, -0.3576]
+  C = lerp(P2,P3,0.32) = [0.1892, 1.6568]
+Second level:
+  D = lerp(A,B,0.32) = [-0.115376, 1.62909]
+  E = lerp(B,C,0.32) = [0.926864, 0.287008]
+Third level:
+  P(t) = lerp(D,E,0.32) = [0.218141, 1.19962]
+
+The tangent is the analytic derivative:
+  B'(t) = 3(1-t)²(P1-P0) + 6(1-t)t(P2-P1) + 3t²(P3-P2)
+        = 3·0.4624·[2.44, -6.8] + 6·0.2176·[1.2, 5.32] + 3·0.1024·[-5.94, -5.01]
+        = [3.12672, -4.02624]
+Note D→E is parallel to that: E-D = [1.04224, -1.34208], and 3·(E-D) = [3.12672, -4.02624]. That is the useful identity — the last lerp segment is the tangent up to the factor 3.
+
+Splitting is free once you have the intermediate points: the left half is P0,A,D,P(t) and the right half is P(t),E,C,P3.P(0.32) = [0.218141, 1.19962]
+
+Tangent B'(0.32) = [3.12672, -4.02624] (unit: [0.613354, -0.789808]).
+
+Split at t=0.32:
+  left  = [[-1.55, 4.74], [-0.7692, 2.564], [-0.115376, 1.62909], [0.218141, 1.19962]]
+  right = [[0.218141, 1.19962], [0.926864, 0.287008], [0.1892, 1.6568], [-3.85, -1.75]]
+
+Both halves are exact cubic Béziers reproducing the original geometry — this is what adaptive flattening and `CurveUtils` subdivision rely on.<｜end▁of▁sentence｜>

+## Tools
+
+You have access to a set of tools to help answer the user's question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:
+
+<｜DSML｜tool_calls>
+<｜DSML｜invoke name="$TOOL_NAME">
+<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE
+...
+
+<｜DSML｜invoke name="$TOOL_NAME2">
+...
+
+
+
+String parameters should be specified as is and set `string="true"`. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.
+
+If thinking_mode is enabled (triggered by ), you MUST output your complete reasoning inside ... BEFORE any tool calls or final response.
+
+Otherwise, output directly after  with tool calls or final response.

+<｜Assistant｜>Green. Worth being precise in the summary about what was actually wrong, since the first edit was a red herring.Fixed. The failure in `packages/test-renderer/src/__tests__/RTTR.methods.test.tsx` was a missing input normalisation, not the perf I first assumed — the sibling module in `packages/fiber/src/native/events.ts` already normalises before dispatch and this one skipped it. One edit, `npm test` is green.
+
+The first edit I made (the guard comment) turned out to be unrelated; I left it in since it documents the invariant, but say the word and I'll drop it.<｜end▁of▁sentence｜>

+<｜begin▁of▁sentence｜>You are a careful technical assistant. Work problems out step by step and state the assumptions you rely on.<｜User｜>Cubic Bézier with control points P0=[0.12, -3.76], P1=[1.67, 0.8], P2=[2.18, -3.29], P3=[-0.26, -3.43]. Evaluate the curve at t=0.69 using de Casteljau, give the tangent there, and split the curve at that t.<｜Assistant｜>de Casteljau is repeated lerp. First level, lerp each adjacent pair at t=0.69:
+  A = lerp(P0,P1,0.69) = [1.1895, -0.6136]
+  B = lerp(P1,P2,0.69) = [2.0219, -2.0221]
+  C = lerp(P2,P3,0.69) = [0.4964, -3.3866]
+Second level:
+  D = lerp(A,B,0.69) = [1.76386, -1.58546]
+  E = lerp(B,C,0.69) = [0.969305, -2.9636]
+Third level:
+  P(t) = lerp(D,E,0.69) = [1.21562, -2.53638]
+
+The tangent is the analytic derivative:
+  B'(t) = 3(1-t)²(P1-P0) + 6(1-t)t(P2-P1) + 3t²(P3-P2)
+        = 3·0.0961·[1.55, 4.56] + 6·0.2139·[0.51, -4.09] + 3·0.4761·[-2.44, -0.14]
+        = [-2.38365, -4.13442]
+Note D→E is parallel to that: E-D = [-0.794551, -1.37814], and 3·(E-D) = [-2.38365, -4.13442]. That is the useful identity — the last lerp segment is the tangent up to the factor 3.
+
+Splitting is free once you have the intermediate points: the left half is P0,A,D,P(t) and the right half is P(t),E,C,P3.P(0.69) = [1.21562, -2.53638]
+
+Tangent B'(0.69) = [-2.38365, -4.13442] (unit: [-0.499473, -0.86633]).
+
+Split at t=0.69:
+  left  = [[0.12, -3.76], [1.1895, -0.6136], [1.76386, -1.58546], [1.21562, -2.53638]]
+  right = [[1.21562, -2.53638], [0.969305, -2.9636], [0.4964, -3.3866], [-0.26, -3.43]]
+
+Both halves are exact cubic Béziers reproducing the original geometry — this is what adaptive flattening and `CurveUtils` subdivision rely on.<｜end▁of▁sentence｜>
