+# Proposed task-execution-grant immutable projection
|
|||
|
|
+
|
|||
|
|
+RPF-WP-0035-T12 source preparation, 2026-10-16. This proposes and implements the
|
|||
|
|
+owner's pure projection/binding code; it approves no grant and registers no native
|
|||
|
|
+or legacy delegated applier. Existing production readiness remains refused.
|
|||
|
|
+
|
|||
|
|
+Use the existing `task-execution-grant` CCR type proposed by Platform and
|
|||
|
|
+SECRETS-WP-0013. Use the existing execution descriptor's
|
|||
|
|
+`execution_grant_ccr_id` and `grant_immutable_sha256` join. No second consumer
|
|||
|
|
+execution descriptor, authorization token or broker is introduced.
|
|||
|
|
+
|
|||
|
|
+`scripts/task_execution_grant.py` defines a closed CCR root with existing identity,
|
|||
|
|
+status/date/requester/review/target fields, effectful `execution` and `openbao`
|
|||
|
|
+objects, and an explicitly typed evidence event list. `immutable_digest` uses
|
|||
|
|
+SHA256 over sorted compact ASCII JSON of the complete validated projection.
|
|||
|
|
+It includes status, updated, title, requester, review requirements/approvers,
|
|||
|
|
+target coordinates, all execution inputs, generated HCL, token body and cleanup.
|
|||
|
|
+It excludes exactly `review.comments` and `evidence.events` by replacing those
|
|||
|
|
+lists with empty lists. No generic evidence-prefix stripping or caller-selected
|
|||
|
|
+exclusion exists. Unknown root/review/evidence fields refuse. Fields nested in
|
|||
|
|
+execution/openbao remain fully hashed and must exactly match independently
|
|||
|
|
+reconstructed effects when bound. Projection alone is not semantic admission.
|
|||
|
|
+
|
|||
|
|
+Reviews have exactly at/reviewer/decision/comment; evidence events have exactly
|
|||
|
|
+at/kind/result/reference_sha256. These append-only annotations cannot supply a
|
|||
|
|
+runtime approval or become policy inputs. `require_append_only` independently
|
|||
|
|
+checks that each old list is an exact prefix of the new list and that the
|
|||
|
|
+immutable projection is unchanged. Removal, replacement and reordering refuse.
|
|||
|
|
+The owner must use known history when checking an update; a current file cannot
|
|||
|
|
+prove its own history. Updating `updated` or status changes the digest and requires
|
|||
|
|
+a new exact join. There is no guessed exclusion for convenience.
|
|||
|
|
+
|
|||
|
|
+The compiler's optional independently installed `OwnerConfig.grant_filename`
|
|||
|
|
+selects one different CCR file under credential-change-requests. It adds exactly
|
|||
|
|
+that record and the pure validator source to the closed owner source-pin set.
|
|||
|
|
+The compiler reads verified bytes and executes the pinned validator source directly,
|
|||
|
|
+without a module-cache substitute. It reconstructs the entire effectful grant:
|
|||
|
|
+
|
|||
|
|
+- The existing descriptor, excluding only its own `grant_immutable_sha256` to avoid
|
|||
|
|
+ self-reference, plus action/catalogue and the actual owner source pins. The
|
|||
|
|
+ record's own raw file hash is omitted from its own source-pin projection; all
|
|||
|
|
+ other source hashes, including the validator, remain included.
|
|||
|
|
+- Deterministic `cleanup_specs(operation_id)`, its fixed private credential slots,
|
|||
|
|
+ exact revoke/verification and delete/verification paths/methods, declared
|
|||
|
|
+ no-issue/no-create branches, one reserved cleanup use and the cleanup obligation
|
|||
|
|
+ after business expiry.
|
|||
|
|
+- Exact operation-specific task policy HCL on the two independently compiled
|
|||
|
|
+ metadata endpoints plus revoke-self, and the exact parented service token body:
|
|||
|
|
+ nonrenewable, no default policies, no identity policies, 30–120s TTL and twelve
|
|||
|
|
+ uses. No caller HCL, body, handle, wildcard or mount administration is accepted.
|
|||
|
|
+
|
|||
|
|
+It compares those structures with the owner record and compares the resulting
|
|||
|
|
+immutable SHA and grant ID with the existing descriptor fields before returning
|
|||
|
|
+a bound Plan. Unknown or changed effectful fields fail equality even if the caller
|
|||
|
|
+re-pins the record and recomputes its digest. The complete descriptor must still
|
|||
|
|
+match independently installed owner descriptor bytes. Raw source file hashes and
|
|||
|
|
+immutable hashes serve different purposes: even an annotation-only file edit
|
|||
|
|
+requires owner source-pin refresh and Plan reconstruction; it does not silently
|
|||
|
|
+change the grant immutable digest or restore an admission.
|
|||
|
|
+
|
|||
|
|
+The disposable native adapter now refuses missing/unbound or proposed grants,
|
|||
|
|
+rebuilds the exact bound Plan from pinned owner sources at construction, checks
|
|||
|
|
+all source pins immediately before each native request, reconstructs each actual
|
|||
|
|
+metadata body via the compiler and compares actual token/ACL bodies with the bound
|
|||
|
|
+projection before issuing them. It still requires the same live postconsume
|
|||
|
|
+journal admission and the live owner-spawned disposable OpenBao process handle.
|
|||
|
|
+Native fault tests explicitly use synthetic approved copies in temporary directories;
|
|||
|
|
+no real owner CCR status, policy or grant is created or changed.
|
|||
|
|
+
|
|||
|
|
+The normal credential-change CLI deliberately continues to reject this type for
|
|||
|
|
+execution. Adding it to LANE_MODULES would expose generic applier methods and is
|
|||
|
|
+not part of this source preparation. The pure validator is actually called by
|
|||
|
|
+the compiler/native fixture path; it is not a paper-only schema. An owner can
|
|||
|
|
+review this projection and later integrate source validation/recording into the
|
|||
|
|
+CCR tooling without enabling execution.
|
|||
|
|
+
|
|||
|
|
+Remaining production work is now specific: approve/adopt this owner CCR projection;
|
|||
|
|
+verify owner source/grant admission and immutable target CCR semantics; integrate
|
|||
|
|
+authenticated principal, served exact claim/PDP/package and independent signed
|
|||
|
|
+consume; finish total native baseline/readback normalization/conflict control;
|
|||
|
|
+install bounded isolated owner runtime, trusted served deadlines/use accounting,
|
|||
|
|
+audit and protected recovery; then run the exact founder-scoped attended trial.
|
|||
|
|
+Neither an approved string nor this projection authenticates human approval.
|
|||
|
|
+Approval replay prevention and uncertain backend-effect reconciliation remain
|
|||
|
|
+separate. T12 and Secrets WP13 stay open.
