Use WP Codebox v0.12.16 workspace runtime

.github/workflows/README.md

@@ -14,7 +14,7 @@ The reusable workflow declares the expected typed review artifacts for Docs Agen
 
 The target repository grants `contents: write`, `pull-requests: write`, and `issues: write`. Docs Agent forwards the caller-scoped `${{ github.token }}` to WP Codebox for same-repository publication, so consumers do not configure `ACCESS_TOKEN`. `OPENAI_API_KEY` is an optional workflow secret and is required only for a live OpenAI run; skipped and dry-run calls do not require it. `EXTERNAL_PACKAGE_SOURCE_POLICY` remains a separate required v1 JSON secret. Migrate its value to the exact one-line JSON in the root README: it authorizes the selected Docs Agent package, the pinned Agents API component, the pinned PHP AI Client overlay, and the checksum-pinned OpenAI provider artifact. Both secrets are forwarded to WP Codebox without serialization into the task descriptor.
 
-Docs Agent consumes the released [WP Codebox v0.12.14](https://github.com/Automattic/wp-codebox/releases/tag/v0.12.14) workflow and passes the matching `wp_codebox_release_ref: v0.12.14` input. WP Codebox validates that the paired tags match, resolves the release tag, verifies its package version, materializes the declared native runtime closure, and executes the selected imported package identity. It seeds a sandbox-local copy-on-write workspace and exposes the workspace tools only inside that sandbox. WP Codebox applies the returned bounded patch to the host workspace, runs validation and verification there, then publishes approved host changes. Provider artifacts retain only canonical runtime-source provenance: uploads contain allowlisted review artifacts, controlled workflow envelopes, and provenance metadata, never prepared source bytes. Before persisting workflow results or artifact uploads, WP Codebox sanitizes private runtime paths from nested values, object keys, diagnostics, and command arguments. Lifecycle failures publish a normalized failed result even when artifact preparation cannot complete. Diagnostic messages that name runtime classes remain reviewable; PHP-shaped runtime source remains blocked even under a reviewer-safe extension. See [WP Codebox #1767](https://github.com/Automattic/wp-codebox/issues/1767), [WP Codebox #1784](https://github.com/Automattic/wp-codebox/issues/1784), [WP Codebox #1782](https://github.com/Automattic/wp-codebox/pull/1782), and [WP Codebox #1785](https://github.com/Automattic/wp-codebox/pull/1785).

WP Codebox validates that the paired tags match, resolves the release tag, verifies its package version, materializes the declared native runtime closure, and executes the selected imported package identity. It creates a secret-filtered external seed snapshot and passes it through canonical `task_input.workspaces` for the sandbox-local copy-on-write workspace. Canonical changed-files and patch references become actionable host-workspace changes; WP Codebox applies the bounded patch, runs validation and verification, then publishes approved host changes. Provider artifacts retain only canonical runtime-source and seed provenance: uploads contain allowlisted review artifacts, controlled workflow envelopes, and provenance metadata, never prepared source bytes or temporary snapshot paths. Before persisting workflow results or artifact uploads, WP Codebox sanitizes private runtime paths from nested values, object keys, diagnostics, and command arguments. Lifecycle and downstream failures retain normalized runtime evidence in their normalized failed result, even when artifact preparation cannot complete.
