APPROVAL-WP-0001 — v0.7 alignment and the engine spine

Evolve this repository from a v0.5 seed INTENT into a v0.7-aligned PIP with the contracts and first implementation that make Canon T-06 passable and unblock FLEX-WP-0017 T03/T05.

Source:

• net-kingdom/canon/standards/security-layer-model_v0.7.md (accepted)
• net-kingdom/SECURITY-COMPANION.md v0.2
• history/2026-08-29-security-layer-model-v0.7-scope-intent-review.md

Rule of the workplan. Contracts before code. Consumption is not implemented until GH-WP-0002-T06 settles it. A reachable mutation that guesses the three races is a defect, not a prototype.

Peer work this does not own and must not duplicate: GH-WP-0002 (T02 outbox wire, T03 revocation failure mode, T04 detection surface, T06 consumption ordering), FLEX-WP-0017 T03/T05, AUDIT-IN-0001.

T01 — Align declaration to the accepted statute

id: APPROVAL-WP-0001-T01
status: done
priority: high
state_hub_task_id: "090ab9d5-1467-5a82-b3cd-ac4215bec0f0"

2026-08-29: INTENT frontmatter layer: Engine / role: PIP; aligned to v0.7 (PIP typing, threat decomposition, load-bearing cadence, custody closed, consumption as mutation, issuer/freshness, Railiance non-axis). SCOPE.md written as first-cut boundary with standard sections. layer.yaml declared in this repository's own voice. Review filed under history/. Registered with State Hub (infotech, topic custodian). Register's bootstrap workplan was discarded: it collided on APPROVAL-WP-0001 and its three tasks are already discharged by this file, AGENTS.md, and SCOPE.md.

T02 — Publish the approval claim contract

id: APPROVAL-WP-0001-T02
status: todo
priority: high
state_hub_task_id: "ca2ec789-b760-525a-9960-95d15760191e"

Specify the input claim access-engine consumes: approval identifier, canonical-binding digest over the same binding the PDP already computes, issuer (this engine), and freshness. Schema and examples in-repo.

Until Taxonomy's request-claim schema exists (statute §17, ownership proposed not assigned), this is the boundary contract. Mark it as yielding to Taxonomy; do not treat a local shape as permanent.

Acceptance: a document access-engine can implement a consumer against without reading this engine's source; wrong-action / wrong-target / wrong-scope are distinguishable; a PDP can state a deadline for this input class.

T03 — Specify the local transactional-outbox contract

id: APPROVAL-WP-0001-T03
status: todo
priority: high
state_hub_task_id: "a2eb2e8f-9b49-598e-b4a1-fb93e65f1bf3"

Event classes (issuance, use, supersession, revocation, and the heartbeat class T04 needs), same transaction as the object mutation, queue local to this engine, at-least-once into the outbox (audit-core dedupes on event id). No synchronous audit-core call inside the state-change transaction.

Coordinate with GH-WP-0002-T02; do not author doctrine this engine does not own. INTENT already states the boundary and the locality.

Acceptance: a wire contract another repository can review; an implementer cannot satisfy it by emitting synchronously to audit-core.

T04 — Declare load-bearing cadence as heartbeat or reconciliation

id: APPROVAL-WP-0001-T04
status: todo
priority: high
state_hub_task_id: "fce0df25-0106-5c0a-8187-87b956ca6220"

Approval evidence is load-bearing and low-volume. Rate monitoring is the wrong form (statute §9.6). Publish the source-side declaration: expected classes, the heartbeat (nothing to report, signed, itself able to go missing) and/or reconciliation of this engine's transitions against audit-core event counts per class.

Coordinate with GH-WP-0002-T04, which is the detection surface. This task is the source that surface reads.

Acceptance: layer.yaml evidence.cadence_status is no longer undeclared; a missing heartbeat or a count divergence is specified as a finding, not as a log line.

T05 — Wait on consumption ordering; do not implement it

id: APPROVAL-WP-0001-T05
status: wait
priority: high
state_hub_task_id: "204bdfeb-a669-569e-a654-10c1a9fcacbc"

Blocked on GH-WP-0002-T06 / access-engine. The three races (allow never consumed; double consumption; consume after failed action) are named in statute §9.7.4 and §16. This engine performs the mutation; it does not choose the signal, the point relative to the decision, or the handling of the three states.

Acceptance: a written contract both engines have assented to, recorded here, then a consume path. Until then, no consume endpoint, no inferred consumption from a decision record, no demo that "just consumes on allow".

T06 — Durable object, closed state machine, authenticated entries

id: APPROVAL-WP-0001-T06
status: todo
priority: high
state_hub_task_id: "44c4997b-6833-5540-a554-0e24210809f2"

Depends on T02 and T03. Implement the object and the machine in SCOPE: identifiers; bindings (action, target, actor, principal, purpose, validity window, approvers); authenticated entries; distinct-approver counting; CAS supersession; validity/expiry; revocation without holder cooperation.

Do not ship a public consume until T05 is unblocked. Internal CAS consumption may exist behind an unexported seam so T08 can be tested without guessing the ordering contract.

Acceptance: state transitions are total and reconstructable; two concurrent supersessions cannot both succeed; distinct-approver requirements fail closed on duplicates; revocation is effective at the next introspection.

T07 — Introspection API as input claims

id: APPROVAL-WP-0001-T07
status: todo
priority: high
state_hub_task_id: "ea51499d-ced5-50fa-b852-396719a8c0f4"

Depends on T02 and T06. An API that answers INTENT's question and returns the T02 claim. No endpoint answers "may this actor do X". Fail-closed when this engine's own store is unavailable.

Acceptance: access-engine can fetch a claim; a decision rendered against approval A for request R cannot be replayed for R' on the digest; tests forbid a decision-shaped response.

T08 — Local outbox in the mutation transaction

id: APPROVAL-WP-0001-T08
status: todo
priority: high
state_hub_task_id: "b9267011-71b3-5138-a3f9-5256374a6b3b"

Depends on T03 and T06. Every issuance, use, supersession, and revocation inserts the outbox row in the same transaction. Drain is asynchronous. audit-core outage does not block a revocation.

Acceptance: a test that fails the transaction when emission fails, not an inspection of the code; a test that revokes while the evidence engine is unreachable; no path where the state change commits and the outbox row does not.

T09 — Canon T-06 and the FLEX-WP-0017 handoff

id: APPROVAL-WP-0001-T09
status: todo
priority: medium
state_hub_task_id: "b4946568-5dda-5bd7-9941-83a5f0137700"

Depends on T07, T08, and T05 (the last only for the consume-side replay cases). Point Canon T-06 — Approval Replay at a live implementation. Hand access-engine / secrets-engine a claim they can validate before privileged production actions (FLEX-WP-0017 T03/T05).

Acceptance: T-06 passes; T03 is unblocked on the object (not on a hub substitute); T05 remains blocked only on consumption ordering if T05 of this workplan is still wait, never on a missing object or a missing digest.
