Advance Docs Agent to WP Codebox v0.12.28 (#164)

@@ -16,7 +16,7 @@ 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 v0.12.27](https://github.com/Automattic/wp-codebox/releases/tag/v0.12.27) workflow and passes the matching `wp_codebox_release_ref: v0.12.27` input. The release tag resolves to immutable revision `65cc5fb4699cb7c2df13d04b4715c97097ac7565`, which is distinct from the fixed Docs Agent package revision. WP Codebox validates the paired tags, materializes the declared native runtime closure, executes the selected package, applies bounded workspace changes, runs verification, and publishes approved host changes. Its published assets are `01-wp-codebox.zip` and `02-wp-codebox-workspace-0.12.27.tgz`; the private package-recovery manifest is intentionally not a reviewer asset.

 Provider artifacts retain only allowlisted review artifacts, controlled workflow envelopes, and canonical runtime-source and seed provenance. WP Codebox v0.12.24 uploads a reviewer-safe workflow-result projection: public control, verification, publication, output-projection, access, failure, artifact-declaration, and canonical transcript-provenance fields remain, while raw `runtime_result`, `outputs.engine_data`, model/provider/tool payloads, source content, private paths, and secrets are excluded. Before persistence or upload, it sanitizes private runtime paths from nested values, object keys, diagnostics, and command arguments. WP Codebox captures one trusted canonical `codebox-transcript` through a pre-sanitization reviewer-evidence descriptor, validates its artifact-root containment, schema, digest, and size, then emits the compact reviewer transcript as a `wp-codebox/reviewer-agent-transcript/v1` projection. Before apply-back, it compares the seed identity with the host workspace identity; rejected patches preserve the expected and actual identities plus patch and changed-file evidence for upload. Its pre-redaction trusted apply input preserves machine-applicable patch bytes in a private channel that is removed before durable artifact sanitization, as fixed in [WP Codebox #1842](https://github.com/Automattic/wp-codebox/pull/1842). The canonical transcript remains the bounded tool-observability surface. Lifecycle and downstream failures retain runtime evidence in their internal normalized failed result even when artifact preparation cannot complete. Diagnostic messages that name runtime classes remain reviewable, while PHP-shaped runtime source remains blocked. See [WP Codebox #1767](https://github.com/Automattic/wp-codebox/issues/1767), [WP Codebox #1814](https://github.com/Automattic/wp-codebox/issues/1814), [WP Codebox #1815](https://github.com/Automattic/wp-codebox/pull/1815), and [WP Codebox #1823](https://github.com/Automattic/wp-codebox/pull/1823). Successful canonical reviewer-evidence reference: [run `29350690551`](https://github.com/Automattic/build-with-wordpress/actions/runs/29350690551). The [hosted failure `29468956857`](https://github.com/Automattic/agents-api/actions/runs/29468956857) executed WP Codebox v0.12.20, published [Agents API #430](https://github.com/Automattic/agents-api/pull/430), then failed during upload preparation; it motivated #1814/#1815 and is not a successful v0.12.24 reviewer-safe workflow-result run.

 ## Docs Agent Runner Recipe
 
 Docs Agent workflow call sites prepare a portable recipe instead of calling a concrete runner. Docs Agent owns the native package, lane, artifact, prompt, and workspace mapping. Consumers depend on Docs Agent inputs and review artifacts, not runner internals.
