## Verdict
**ITERATE**

## Claim Checks

- The immutable target was read in full. The RALPLAN index records `stage-36-revision.md` at revision stage 36 with SHA-256 `c70c3217cba0becbcd2bbcc836b5fb1af8f6e9d44608e43dda17a1d0277d99f0`, matching the assignment.
- The Stage-35 sealed-construction closure remains sound. Current `CustomerRuntime` has only `spec` and `data_root` (`checkin_cli/customer_coaching.py:363-401`), the gateway constructs `WizardService(wizard_root)` directly (`gateway/platforms/nutrition_coaching.py:350-395`), and `WizardService` constructs a bare `EventStore(home)` (`checkin_cli/wizard.py:544-546`). The frozen loader-minted `RegisteredCustomerBinding`, private construction tokens, and disjoint `for_registered`/`for_standalone` factories give executors an implementable migration seam and remove the optional registered-mode bypass. Existing direct CLI/admin/test constructors were also verified and are covered by the plan's explicit registered-versus-standalone callsite migration.
- The Stage-35 acyclic digest closure also remains clean. The specified order `spec_core_digest -> diagnostic_transport_binding_digest -> spec_digest -> authority_digest` has explicit exclusions and durable inputs, propagates the relevant digests to session/transition/capability/reservation rows, and retains Python `is` only as an additional process-local check. The fixed-byte independent recomputation tests are sufficient to verify ordering, exclusions, restart reconstruction, and absence of object representation.
- Revision 36 fixes the sole Stage-35 Architect defect in principle and at the correct owner. Current `AdaptiveNutritionCoordinator.deliver_latest_once` creates `delivery_attempt_started` inside its own store lock and only later dispatches through mutable/generic `send_adaptive_customer` (`gateway/platforms/nutrition_coaching.py:10619-11168`); the transport then rereads and consumes that reservation (`:11643-11813`). Moving validation, reservation creation, committed-row reread, verified capability creation, provider start, frozen transport invocation, and terminal persistence under `DiagnosticHost._admission_lock` supplies the missing reserve-before-verify success path and preserves Stage-33 close linearization. The close-first and reserve-first schedules are now coherent.
- Representative simulation succeeds for a fresh candidate: the activated child creates a non-authorizing candidate from persisted approved state; the authority reloads every live pin, rejects candidate mismatches before rows, appends and rereads the reservation under the adaptive store lock while the host admission lock remains held, returns only pinned bytes/destination, and the host calls only the frozen diagnostic sender before durable terminalization.
- Representative simulation does not have a unique implementation for replay/restart. `reserve_and_verify(...)` is declared to return only `VerifiedDiagnosticReservation`, but the same paragraph says an existing terminal/consumed reservation returns a separate typed duplicate/no-send result. The host's stated exact order then unconditionally passes the result to `verify_provider_start`. No duplicate result type, return union, branch, or host response is defined.
- The crash-immediately-after-reservation case is also under-specified. The text defines terminal/consumed and conflicting-dedupe outcomes but not an exact matching, unconsumed `delivery_attempt_started` row. That is precisely the row present after the named crash point. Retained Stage-33 recovery requires no resend, but Revision 36 must say whether startup recovery terminalizes it before revalidation or `reserve_and_verify` returns a non-authorizing no-send result; it must never reconstruct `VerifiedDiagnosticReservation` provider authority from that row.
- The asserted single reservation owner needs one enforcement sentence and test. The current diagnostic child would still expose the ordinary public `deliver_latest_once` reservation branch. “Bypassed” at the configured callsite does not by itself make “No reservation can be created outside this method in diagnostic mode” true. The existing `RegisteredCustomerBinding.mode` is an available discriminator, but the plan does not require the ordinary branch to reject diagnostic mode before rows/provider or test direct invocation.

## Missing Evidence

Definitely missing:

1. A closed return/result algebra for `reserve_and_verify`: fresh verified authority versus duplicate/no-send, including the exact `DiagnosticHost.deliver` branch and stable caller-visible result.
2. An explicit outcome for an exact unconsumed reservation left by a crash, tied to the retained startup-recovery-before-revalidation rule and proving that provider authority is never recreated.
3. Mechanical rejection of the ordinary coordinator reservation API in diagnostic mode, with a direct bypass test asserting row/provider delta zero. Merely routing normal calls through the host is not equivalent to enforcing the sole-writer claim.

## Approval Boundary

Execution may proceed with the Stage-35 registered/standalone factory split, the acyclic durable digest schema, and the Revision-36 fresh-candidate host-owned reservation architecture. Diagnostic delivery execution is not yet approved until replay/restart result typing and the diagnostic-mode ordinary-branch gate are explicit. All retained Stage-33 read-lock, packaging, recovery, route-generation, timeout/cancellation, human-only, and no-live-Telegram boundaries remain unchanged.

## Summary

- **Clarity:** High for fresh delivery; contradictory return typing and an undefined crash-row branch remain.
- **Verifiability:** Strong race/provider-zero tests, but the result algebra and direct ordinary-branch bypass need exact assertions.
- **Completeness:** Stage-35 constructors and digests remain complete; reservation closure is one bounded revision short.
- **Big Picture:** Host-owned reserve-and-verify is the right linearization design and removes the prior coordinator-to-host gap.
- **Principle/Option Consistency:** Durable/process identity and sealed-factory principles are consistent; a merely bypassed public ordinary reservation path conflicts with the claimed sole-owner invariant.
- **Alternatives Depth:** Adequate cumulatively; generic pre-host reservation remains correctly rejected.
- **Risk/Verification Rigor:** Fresh, close-first, reserve-first, pin-mismatch, and success paths are strong; crash replay and API-bypass behavior need binding semantics.

## Required Changes

1. Define a named duplicate/no-send type and change `reserve_and_verify` to an explicit union (or raise a named non-error duplicate outcome). Specify that `DiagnosticHost.deliver` branches before `verify_provider_start`, returns a stable duplicate result, and produces no new row/provider call.
2. Enumerate existing-reservation states under the dedupe key: no row creates and verifies once; exact unconsumed started row is recovered/terminalized or returned as non-authorizing no-send; exact consumed/terminal row returns duplicate; any pin/body/destination mismatch conflicts. Tie restart ordering to Stage-33 recovery and test each row/provider delta.
3. Require the ordinary coordinator reservation/delivery entry point to reject a diagnostic-bound runtime before reservation, using the sealed binding mode or an equally explicit host-only capability. Add a direct-call test proving the host method is the only diagnostic reservation writer.
