Inline findScope and blocked-key checks, shorten ownPropertyOnly docs,
and drop implementation-detail push() unit tests.
Co-authored-by: Cursor <[email protected]>
Drop null-prototype passthrough in push(), inline blocked-key checks,
remove redundant createScope at include tag, trim verbose docs, and
drop implementation-detail unit tests.

Restore null-prototype hardening for Jekyll include bindings, colocate blocked-key checks with readJSProperty, align ownPropertyOnly JSDoc with security docs, and drop integration tests duplicated in context.spec.

Centralize null-prototype scope creation in push() so callers pass plain objects; Drop instances and existing null-proto frames are pushed as-is. Remove sanitizeScope in favor of createScope via Object.assign.
Move readSize, readFirst, and readLast to private Context methods using this.ownPropertyOnly. Remove redundant shouldBlockScopeKeyRead from findScope.
Co-authored-by: Cursor <[email protected]>
Use shouldBlockScopeKeyRead in findScope hasKey so inherited
constructor/__proto__/prototype do not falsely match environments.
Remove redundant globals hasKey check; globals remains the fallback scope.

Block __proto__, constructor, and prototype only when ownPropertyOnly
is true or when access would traverse the prototype chain. Allow own
properties with those names when ownPropertyOnly is false.
Co-authored-by: Cursor <[email protected]>
Block writes to dangerous keys in assign/capture/increment/decrement, use own-property Symbol.iterator for plain objects when ownPropertyOnly is true, fix inherited size reads, and sanitize filter iteration scopes.

* docs: note maxDepth stack overflow applies to renderSync only
Explain why async render does not need maxDepth for stack protection based on generator/toPromise driving.
Co-authored-by: Cursor <[email protected]>
* refactor: track maxDepth via depthLimit Limiter on Context
Replace increaseDepth/decreaseDepth with a shared Limiter that supports
paired use/release, matching templateLimit and outputLengthLimit patterns.

* fix: remove spurious diff noise in filter files
Restore misc.ts from origin/next with LF line endings and re-apply only
memoryLimit removal, avoiding CRLF and blank-line churn in the export block.

* fix: enforce ownPropertyOnly for inherited array indices
Route array index access (including negative indices, first/last, and the
first/last filters) through a shared readArrayElement helper so that
ownPropertyOnly hides prototype-inherited array indices, closing the
GHSA-fwxr-j5w2-587m bypass. The option's scope (property/index access
only, not filter transforms or iteration) is documented on the option.

* fix(filters): invoke Array.prototype methods on unsanitized array values
Call built-ins via Array.prototype.<m>.call(...) for values that come
from scope (join, compact, concat, slice, where/reject) so an overridden
instance method on unsanitized data cannot hijack filter behavior.
Methods on freshly-created arrays are left as-is.

* fix(filters): use String.prototype.slice for the string branch of slice
Route the non-array branch through String.prototype.slice.call so the
slice filter never dispatches through a possibly-overridden instance
method, matching the Array.prototype guard.

* docs: add GitHub buttons and improve option docs
* chore: replace husky with prepush check
* docs: revamp homepage and switch to custom GitHub buttons
- Make the docs English-only by removing all zh-cn content, the language switcher UI, and related JS/config
- Rework homepage feature cards (Safe & Typed, Pure JavaScript, Shopify & Jekyll, Streaming) and refresh section colors/layout
- Replace buttons.github.io with custom Star/Sponsor buttons featuring a live star count and dark-mode support
- Drop the buttons.js script and tidy banner, header, footer, and share partials

- Add createScope() building Object.create(null) with optional own props
- Initialize context stack bottom with createScope() for assign/capture
- Push null-proto scopes from for, tablerow, block, layout, include (incl. Jekyll)

Child contexts from spawn() re-derived ownPropertyOnly from Liquid opts
only, dropping per-render RenderOptions overrides. That broke the contract
that parseAndRender(..., { ownPropertyOnly: true }) locks down a single
render, including partials loaded via {% render %}.
Add regression test matching prototype-chain leak PoC.
Co-authored-by: Cursor <[email protected]>
Use _getFromScope for property access in sort/sort_natural filters to respect the ownPropertyOnly security option, preventing prototype chain traversal that could leak sensitive inherited properties.
Also extract shared sortBy helper, add orderedCompare with nil handling consistent with caseInsensitiveCompare and Ruby Liquid.
