+### Interrupted site apply
+
+`site apply` holds one lock per WordPress blog, shared by every Block Runner site
+identity. A held lock is refused even when its token matches the journal; a token
+cannot prove that an earlier WP-CLI or PHP process has stopped. Older namespace
+locks also block new applies.
+
+After an interruption, preserve the confirmed plan, journal and WordPress operation
+marker. First establish that every executor and its WP-CLI/PHP descendants have
+stopped. Inspect the exact lock value and native mutation outcome before removing
+only that observed lock through an operator-controlled compare-and-delete. Keep
+the operation marker and journal. Repeating the same confirmed operation can
+continue only when their ownership and readback evidence prove the outcome;
+unknown effects are never retried automatically.
+

 `site apply` holds one lock per WordPress blog, shared by every Block Runner site
 identity. A held lock is refused even when its token matches the journal; a token
 cannot prove that an earlier WP-CLI or PHP process has stopped. Older namespace

 # Changelog
 
+## Unreleased
+
+- Add block-theme folder validation, in-place markup repair, WordPress 7.1 theme.json schema checks and local part/pattern/preset references.
+- Align native attribute order with WordPress server definitions; send unknown-block warnings to stderr and preserve native Accordion icon placement.
+- Compile caller-authored whole-site intent into a local block theme and page bundle, with explicit media, font and synced-pattern bindings.
+- Add source/target-bound site planning, confirmed owned apply with durable journals, read-only drift and staged pull of saved template/part edits. Theme deployment and activation remain separate.
+- Add mounted-editor theme save proof and controlled whole-site proof. Save persistence does not establish visual fidelity.
+- Update Wesper to 0.5.0 and require Node.js ^22.13.0 || >=24.0.0, dropping Node 20 support.
+- Preserve unmanaged page fields and native publication dates on apply, allow pending first-install pattern media, canonicalise site identity and reduce repeated compilation, snapshots and source scans.
+- Document current theme/site routes and guarded manual interrupted-apply recovery; remove the public proof failure-seeding option and fixed five-page fixture requirement.
+
 ## 0.9.10 — 2026-10-04
 
 - Clarify native intent styling versus HTML/CSS conversion, with runnable native-attribute, headerless-table and sequential library examples. Verified theme layout contracts can override generic block-mapping defaults.

+The folder gate discovers templates, parts and static PHP patterns. It preserves
+pattern metadata headers and skips bodies containing PHP rather than executing them.
+It checks a present `theme.json` against the pinned WordPress 7.1 schema and checks
+local part, pattern and preset references. Block-scoped presets apply to their block
+type. Core-default preset categories can remain explicitly skipped.
+
+`fix --write` is only for theme folders. It canonicalises eligible markup files;
+it does not rewrite `theme.json`. Schema errors fail the aggregate report; strict
+reference failures prevent the affected file from being rewritten. Config-file `strict: true`
+also applies. Review skips and warnings even when the command succeeds.
+
+## Compile a whole site
+
+Use caller-authored `SiteIntent`, with native blocks for each section and editable
+descendants. A whole page or section inside `core/html` does not establish native
+conversion. Existing authored HTML can inform the trees through `convert`; use
+[ASSEMBLE.md](ASSEMBLE.md) for the node schema. Templates surround page content with
+`core/post-content`; they must not duplicate the page body.
+
+Save this minimal input as `site.intent.json`. Omitted page status defaults to draft:
+
+```json
+{
+  "version": 1,
+  "siteId": "sample-studio",
+  "homePageId": "home",
+  "theme": {
+    "slug": "sample-studio",
+    "title": "Sample Studio",

+
+```sh
+mkdir -p assets
+block-runner site compile site.intent.json --asset-root ./assets --out ./site-bundle --strict --json
+```
+
+Compilation writes a new local bundle containing the block theme, page content,
+retained source/assets and a hashed manifest. It passes documents through the existing
+finalisation and theme gates. It does not contact WordPress. Each template/part has a
+`body`; static patterns additionally have `title` and `slug`. Page IDs are stable
+logical identities, separate from routes; `parentId` declares hierarchy.
+
+Declare every asset by `id`, safe relative `path`, `kind` and `role` (`theme-file` or
+`attachment`). `assetUses` bind its `assetId` to a `documentId`, zero-based `nodePath`
+and `attribute` (`url`, `attrs.url`, `attrs.src` or `attrs.id`). Local WOFF/WOFF2 fonts
+need an explicit `fontLicense` redistribution decision; stylesheet `cssUrls` declare
+their referenced theme files. No source CSS or asset is silently inferred as deployed.
+
+For database media, full compilation requires an explicit `--bindings <json>` map
+keyed by asset ID. `--theme-only` emits deployable theme files while retaining pending
+page and synced-pattern bindings. Dependencies used by theme documents must already
+resolve; pending data is not a finished site artifact. `--theme-asset-base-url` supplies
+the deployed base URL when needed. Inspect the JSON diagnostics.
+
+Optional `syncedPatterns` has `version: 1`, `definitions` keyed by logical ID
+(`title`, `body`) and explicit `uses` (`documentId`, `nodePath`, `patternId`, optional
+named override `content`). These are database-owned reusable patterns, distinct from
+static theme PHP files. Keep their native editable structure and declared bindings.
+
+## Plan and apply to WordPress
+
+Deploy and activate the exact compiled theme independently first. Block Runner
+does not deploy or activate it. Use WordPress 7.1 and an explicit WP-CLI target/user.
+For first installs with pending database bindings, plan from the retained intent:
+
+```sh
+block-runner site plan site.intent.json --asset-root ./assets \
+  --wp-path /path/to/wordpress --wp-user 1 --out ./site.plan.json --strict --json
+
+# Review the plan, then supply its exact confirmation hash and a durable journal.
+block-runner site apply site.plan.json --source site.intent.json --asset-root ./assets \
+  --wp-path /path/to/wordpress --wp-user 1 --confirm <hash> --journal ./site.apply.json --strict
+```
+
+`plan` makes a read-only WordPress observation and writes a new local plan. Its
+confirmation binds source/assets, target, principal, active theme and live state.
+Use `--wp-url` for a specific multisite target; `--wp-binary` selects the WP-CLI binary.
+A fully bound bundle can replace the intent as plan/apply source.
+
+`apply` imports declared images, creates or updates owned pages/synced patterns and
+sets the static front page. It does not adopt unrelated records by title or route,
+delete them, or overwrite unmanaged post fields. Pages remaining drafts keep their
+dates; publishing a floating draft uses WordPress's native publication time.
+
+The journal records each step before mutation. A partial or unknown outcome is a
+failed apply, not a completed receipt. Held blog locks are never stolen, even by the
+same journal. After a hard stop, preserve the plan, journal and native operation marker;
+establish that every executor has stopped before guarded operator lock reconciliation.
+There is no automatic lock expiry or recovery command. Never delete a lock blindly
+or retry an uncertain effect without proving its outcome. This is not a transaction
+with concurrent human edits or WordPress hooks.
+
+## Inspect drift and pull saved theme edits
+
+```sh
+block-runner site drift ./site-bundle --wp-path /path/to/wordpress --wp-user 1 --json
+block-runner site pull ./site-bundle --wp-path /path/to/wordpress --wp-user 1 \
+  --select 'part:sample-studio//footer:123' --out ./pull-preview --json
+block-runner site pull ./site-bundle --wp-path /path/to/wordpress --wp-user 1 \
+  --out ./pull-preview --confirm <hash> --json
+```
+
+Drift is read-only: exit codes are 0 clean, 1 actionable, 2 blocked and 3 inspection
+failure. Pull selection is an exact `part:theme//slug:wp-id` or
+`template:theme//slug:wp-id`; replace the example with an observed database override.
+Preview writes only a new local staging directory. Confirmation reuses that directory,
+omits `--select`, and checks fresh target/source/before bytes before updating the
+selected local theme files and sealed manifest. Database overrides remain untouched.
+Pull does not reverse-infer the original intent. Reconcile that retained input and
+recompile before planning another apply; unreconciled bundles are blocked.
+
+## Prove the right result
+
+`proof --theme ./my-theme --wp-env-config ./wp-env.json` saves mounted Site Editor
+content and compares fresh REST bytes with pinned theme files. It honours wp-env's
+effective fixed development port and refuses `autoPort`; a site marker guards the
+browser target. This proves save persistence for the exercised files, not visual fidelity.
+
+`proof --site ./site-bundle --wp-env-config ./wp-env.json` exercises a controlled
+owned sandbox, with a nonempty set of explicitly published pages and declared header
+and footer parts. The minimal draft example above needs those additions first.
+Never use production as the proof fixture. Both routes require the optional pinned
+WordPress/browser tooling; save proof and visual/editor acceptance are separate claims.

 Block Runner is an open-source CLI and JavaScript library from Human Made. It converts supported HTML into native Gutenberg blocks and checks the generated markup with the Gutenberg packages used by the WordPress editor. It can also generate a static registered block: source files you build into a plugin, with native editable blocks inside. Whole-site intent produces a block theme and page content, with separate planning and confirmed apply to WordPress.
 
-This README describes the current repository source. Theme-folder and whole-site workflows, Wesper 0.5.0 and the new Node floor are unreleased; npm 0.9.10 predates them. See [Unreleased changes](CHANGELOG.md#unreleased) before assuming an installed version has these capabilities.
+Theme-folder and whole-site workflows, Wesper 0.5.0 and the Node 22.13/24 floor were introduced in 0.9.11. See the [release notes](CHANGELOG.md#0911--2026-10-13) and check your installed version before using these routes.
 
 **The package makes no AI model calls.** Built-in rules can convert HTML on their own. An external agent can interpret a design and give Block Runner a structured plan to assemble or compile. The optional skill provides instructions for that agent.
