docs+test(hierarchies): end-to-end review follow-ups (M5/M6/M7)

Findings from a 3-lens end-to-end review (correctness, security, tests).
Security review came back clean (cross-repo authz sound, isolation intact,
M5 gate sound modulo the documented manifest-trust boundary). No behavior
changes here — only accuracy + coverage:

- apply_service Phase B2: correct the descendant-expansion comment. The chain
  is COMMITTED ancestry (ancestors() reads the pool), so a reparent in the same
  apply takes effect next apply — same "one more apply" shape the in-tree path
  and group-create reparenting already have. Authz stays sound: the gate and the
  expansion consume the SAME chain (checked == written).
- doc §4.5: document the two known "one more apply / no data risk" limitations
  — reparent-in-same-apply template resolution, and the `{env}` source split
  (declared apps use --env; cross-repo descendants use apps.environment).
- approval journey: give the app real (`[vars]`) content so the editor member's
  AppVarsWrite is actually exercised — the admin-gate test now proves approval
  is ABOVE editor-write, not just "any non-admin is refused". (Vars cascade with
  the app; scripts are ON DELETE RESTRICT and would break AppGuard teardown.)
- templates journey: assert descendant expansions are idempotent (stable row
  ids on re-apply — no churn), matching the in-tree guarantee.

 # PiCloud Changelog
 
-## Unreleased — CMS proof-of-concept remediation
-
-Fixes surfaced by building a full CMS on PiCloud (`examples/cms-poc/`). Pure
-additive surface + one migration (`0077_apps_cors.sql`), no destructive changes.
-
-### Security
-
-- **502 info-leak closed on user routes.** An uncaught script error (incl. a
-  `throw`) on a user route returned HTTP 502 whose body embedded the app UUID,
-  script function names, and source line/col. The 2026-06-11 audit scrub had
-  only covered the execute-by-id path; the user-route (inbox) path still leaked.
-  Both paths now share `scrub_runtime_detail` — the raw detail is logged
-  server-side under a correlation id and the client sees only
-  `script execution error (ref: <uuid>)`.
-
-### Added
-
-- **`docs::find` `$contains` operator** — array-membership via JSONB `@>`, e.g.
-  `docs::find("posts", #{ tags: #{ "$contains": "rust" } })` finds every post
-  tagged `rust`. The inverse of `$in`. Covers per-app and group-shared docs.
-- **App-user role management from the API/CLI** — `pic users add-role --app <app>
-  <user_id> <role>` / `rm-role`, backed by `POST`/`DELETE
-  /api/v1/admin/apps/{id}/users/{user_id}/roles[/{role}]` (`AppUsersAdmin`).
-  Role assignment was previously reachable only from a Rhai script.
-- **Per-app CORS** — `pic apps cors set <app> <origins…>` (or `*`), stored on
-  `apps.cors_allowed_origins`. The orchestrator echoes an allowed `Origin` on
-  every response and answers the `OPTIONS` preflight. Empty = off (unchanged).
-- **Non-JSON request bodies** — a user route no longer 400s on a non-JSON body.
-  `application/x-www-form-urlencoded` → `ctx.request.body` object, `text/*` →
-  string, other types → base64 string; `ctx.request.content_type` added as a
-  convenience. JSON (or unspecified) is unchanged; malformed JSON still 400s.
-- **Binary responses** — a script may return `#{ statusCode, headers,
-  body_base64 }`; the platform decodes the base64 and returns raw bytes with the
-  script-set `Content-Type` (default `application/octet-stream`).
-- **`workflow::run_status(run_id)` SDK** (F-038) — the script that started a run
-  can now poll it: returns `#{ status, output, error, steps: #{ name: status } }`
-  or `()` when no such run belongs to the app. Read-only, same-app scoped (the
-  run's `app_id` is the isolation boundary), same `AppInvoke` gate as
-  `workflow::start`. Closes the gap where run status was platform-admin-API only.
-
-### Fixed
-
-- **`pic apply` "app not found" is now actionable** — points at
-  `pic apps create <slug>` (apply reconciles groups but never creates an app).
-- **Interceptor- and workflow-step-bound scripts no longer warned "no route or
-  trigger"** at plan time — an `[[interceptors]]` binding (F-021) *and* a
-  `[[workflows]]` step `function` (F-037) now count as reachability.
-
-### Notes
-
-- **Workflow `skipped` ≠ `failed` (F-039, by design).** A step whose `when`
-  evaluates false is `skipped` and counts as *satisfied-but-empty* for its
-  dependents — so a step downstream of a skipped one still runs. To gate a
-  dependent on an upstream actually having run, give it its own `when`
-  (e.g. `when = "steps.publish.output.published == true"`), or have the upstream
-  step return an explicit outcome the dependent checks.

-//! §9.4 Service Interceptors — the executor-side before-op hook.
-//!
-//! MVP: `kv::set` / `kv::delete` (private AND group-shared collections) run an
-//! allow/deny interceptor first. The hook resolves the nearest interceptor for
-//! `(service, op)` on the calling app's chain via the injected
-//! `InterceptorService` (a cheap indexed query; `None` = un-hooked → allow, no
-//! further work). The resolver returns a script already **sealed to the owner
-//! that declared the marker** and fully materialized, so we run it straight
-//! through the SAME `invoke()` re-entry core (`run_resolved_blocking`) — no
-//! second dispatch mechanism, no re-resolution by name (which would let a
-//! descendant app shadow a group's guard).
-//!
-//! **Fail closed.** Everything but an explicit allow denies:
-//! - a registered marker whose script is missing/disabled → deny;
-//! - a registered marker with no runnable engine back-reference → deny;
-//! - a return value that is not `#{ allowed: true }` → deny.
-//!
-//! Only a total absence of any marker allows without running anything.
-//!
-//! **Re-entrancy.** An interceptor that itself performs the guarded op (e.g.
-//! an "allow + audit-log" hook that writes KV) must not re-trigger itself. A
-//! thread-local guard, set for the duration of the interceptor's synchronous
-//! execution, makes any nested op the interceptor performs bypass interception.

-// lexically from the importing origin. This verifies the resolver maps
-// Module/NoProvider/NotFound correctly. The full chain semantics (default body
-// up-chain, nearest-declaration tie) are covered by the CLI journey tests.

--- with `depends_on` edges, a per-step `when` condition, input mapping, and a

-//!
-//! Mirrors `kv_api` / `files_api` so the `pic docs … --app` CLI (and a
-//! future dashboard tab) can browse stored documents without a script.
-//! The per-group equivalent shipped first (`group_blobs_api`); this is
-//! its per-app counterpart, filling the one admin-read gap the other
-//! data-plane services already covered. **Read-only by design** — docs
-//! writes go through `docs::create/update/delete` in scripts, which emit
-//! change events the trigger framework depends on; an admin write would
-//! bypass that, so it is deliberately out of scope (matching kv/files).
-//!
-//! Two operations:
-//!   * `GET /apps/{id}/docs?collection=<c>&cursor=&limit=` — list docs in
-//!     a collection (cursor-paginated).
-//!   * `GET /apps/{id}/docs/{collection}/{doc_id}` — fetch one document.
-//!
-//! Capability: `AppDocsRead`, resolved against the app loaded from the
-//! path (same tier the SDK read path uses).

-//!    (anonymous fails closed — shared mutation always needs an authenticated
