Platform acknowledges the exact ADR-0055 recovery observation design
Platform formally acknowledges ADR-0055's design at Platform proposal commit 18b85a4d056b9809ef9c74122416178a02602690. The exact nine publication artifacts and 32 supporting file hashes are recorded in docs/adr0055-proposal/proposal-manifest.json, SHA256 170b580ed67ebb08fb74991fa1a1255120ebe8d21d554b601f7789204e679a66. This acknowledgment applies to that complete artifact set, not an unreviewed future revision. Assignment ADR-0055/platform/001; coordinator 01a0e095-f279-7fd0-a8ef-92ce8f9547fc, host local. Root is the sole canonical publisher/indexer.
Approved design boundary
Platform approves the proposed Ordering package5.0.0 and separately negotiated observation2.0, selected by a single exact Sales-Ordering-Recovery-Observation-Version:2.0 request header and echoed on every successful opted-in response. Omitted negotiation keeps the legacy response grammar; unsupported, duplicate, comma-combined or mismatched negotiation grants no fallback retirement. Original protocol3, close key, descriptor signature, digest and normalizer versions remain unchanged.
Platform approves the exact six-member original_obligation_retired branch, with existing full Identity, original_response_absent:true and unchanged complete RetiredVerified proof. Both Revenue sales_close_admission.original_response and SchedulingBindIntent.response (the Sales-facing original continuation result) must be absent under owner serialization. Neither is the authentic Delivery bind receipt. The retained Delivery receipt/raw facts remain mandatory. A null response or g2 alone cannot authorize retirement, and no original terminal success or failure is fabricated.
The same authenticated exact-original recovery path and sole scope revenue.sales-ordering.close.recover suffice. No new workload policy, caller, route, token reach or financial authority is required by this artifact set. Preserve auth-first nondisclosure, exact descriptor/current-access checks, complete permanent financial sender coverage, current owner proof and the total ten-second Sales source/Task CAS budget. The absence fact is authenticated current owner evidence, not a new admission or financial result.
The whole existing recovery endpoint remains capable of its already-authorized same-original durable resume. The new retirement branch itself causes no new-ID construction, provider send, compensation, writeback or finalization CAS; exact completed-finalization replay may acquire its retained result and fresh observation. An ineligible branch does not override original sender/continuation barriers. An abandoned original remains unable to resume when proof is unavailable, malformed or stale. Sales may retire only the exact original blocker and Task, without replacement, payment, booking or human-admission authority.
Delivery's accepted receipt and current assessment grammar and Coaching's retired-protection interpretation are unchanged. If implementation needs new duties or authority, return for explicit affected-owner review rather than inferring it from this acknowledgment. Existing ADR-0052/0053 deadlines are neither reset nor extended.
Validation and limits
Platform ran the canonical-ready command against a new isolated canonical directory layout populated from current accepted coordination dependencies, with no edits to coordination. It passed 124 proposal checks, the reused accepted observer's 19 checks and 3 strict-parser checks. A deliberate proposed-artifact modification failed its LF source pin. The canonical validator needs only the existing coordination dependencies, makes no network/database call and writes no files. Its manifest records exact accepted dependency and proposal hashes and owner draft provenance.
These checks establish reproducible offline design validation only. Real physical header-duplicate rejection, bounded streamed parser behavior, current authenticated owner proofs, database serialization and permanent sender coverage, same-database Sales retirement and no-new-financial-effect proof remain implementation/release gates. They do not prevent this design acknowledgment, and this acknowledgment does not claim them complete. No Platform production configuration, code, deployment or business flag changed.
Only Platform's acknowledgment is issued here. Revenue, Sales, Delivery and Coaching must provide their own exact-artifact positions; none is inferred from their prior drafts or this memo. Root determines the overall ADR status and accepted publication after the named owner process. This memo does not activate implementation or production.
