docs(matrix): cachekit-rs 0.9.0 ships the empty-key rejection and path-encoding.json 1.1.0 (LAB-8738)

[27Bslash6]

cachekit-rs 0.9.0 (crates.io, 2026-10-02) carries cachekit-rs#100, but two Rust cells still called it unreleased. Both now cite 0.9.0 as the floor, with the date the published .crate was inspected.

• SaaS API — cache-key path encoding, Rust: rejects the empty key since cachekit-rs 0.9.0; the ., .., health, ttl and lock clause (since 0.8.0) is unchanged.
• Test vectors in CI, Rust: path-encoding.json 1.1.0 vendored byte for byte (sha256-pinned) + CI-executed since 0.9.0.

Verified on the published cachekit-rs-0.9.0.crate (sha256 792ee2d3…c775e, equal to the registry checksum): tests/vectors/path-encoding.json is version 1.1.0 and hashes to the sha256 pinned in src/backend/mod.rs, and encode_key rejects "". The 0.8.0 .crate has neither (no path-encoding.json; encode_key rejects only the five reserved segments).

No other cell or row changes. Changelog fragment: changelog.d/20261010_lab-8738.md.

Closes LAB-8738

Kody Guide: Usage and Configuration

Interacting with Kody

• Request a Review: Ask Kody to review your PR manually by adding a comment with the `@kody start-review` command at the root of your PR.

• Provide Feedback: Help Kody learn and improve by reacting to its comments with a 👍 for helpful suggestions or a 👎 if improvements are needed.

Providing Context (Files & MCPs)

Add these hints in your PR description (or a comment) to unlock deeper checks:

• Ticket / Acceptance Criteria: `Refs: ABC-123` (Linear/Jira/Asana/ClickUp/Trello) or a direct ticket link.
• Bugfix Validation: a Sentry/Datadog/Bugsnag event link (or paste the stack trace/error message).
• Endpoint Risk: mention the route (e.g., `POST /api/payments`) or controller/action name.
• Attach a repo file as context: use an explicit marker like `@file:docs/guide.mdx#L10-L50` (replace with your real path).
• API Contract Docs: include `@file:openapi.yaml` or `@file:swagger.json` when changing routes/schemas.
• Definition of Done / Standards: include `@file:DOD.md` or `@file:CONTRIBUTING.md` if your repo has them.
• Design System Source of Truth: include `@file:ui/index.ts` (replace with your DS entrypoint path).
• Feature Flags: include the flag key/name and `@file:flags.ts` / `@file:config.json` (and optionally the PostHog flag name).
• Edge/CDN Rules: link the Cloudflare rule/zone or describe the intended redirect/header behavior.
• Attach an MCP tool output: use `@mcp<provider|tool>` (replace with an installed MCP provider + tool, e.g., `@mcp<sentry|events.search>`).

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Correct the “as since” wording.

Lines 4 and 9 use the ungrammatical phrase “as since”. Replace it with wording such as “available since” in Line 4 and “since” in Line 9.

Also applies to: 9-9
