📝 Summary

Summary by CodeRabbit

  • Documentation
    • Added a record of connections between Resource Algebra, Occupancy Types, Katagoria and related research areas, with connection statuses and a link to the proof-kernel decision.
    • Documented the project’s proof-kernel decision, including the roles of Agda, Idris2, Lean 4 and Isabelle/HOL, and the handling of developments in other proof assistants.
    • Recorded the evidence considered, limitations of the available checks, and resulting implications for language policy, prototypes and Rust verification questions.

Walkthrough

The change adds a proof-kernel decision record covering prover roles, evidence, a falsifier, and related policy consequences. It also adds a dated register of type-family connections and links that register to the decision record.

Systems and components

  • observed — docs (service) was modified; 2 changed files map to changed impact.

Before / after behavior

  • observed — Modified behavior in docs/TYPE-CONNECTIONS.adoc: Adds a dated, pending-merge register describing Resource Algebra’s grade algebra and instances, Occupancy Types’ occupancy properties, and Katagoria’s proposed graduation rule. A second table records the listed connection results and open items, including the stated proof fragments, instance-based results, decision and conjecture. Adds a link to the proof-kernel decision record.
  • observed — Modified behavior in docs/decisions/D-2026-10-12-proof-kernel-ruling.adoc: Adds the decision record’s metadata, status, and rulings on proof-kernel, ABI/runtime, provenance, porting, and archived prover roles.
  • observed — Modified behavior in docs/decisions/D-2026-10-12-proof-kernel-ruling.adoc: Adds the evidence considered for the ruling: codebase investment, the need for a kernel without UIP, Agda’s safety discipline, and the cost of consolidating on Idris2 or Lean.
  • observed — Modified behavior in docs/decisions/D-2026-10-12-proof-kernel-ruling.adoc: Adds a falsifier requiring resource-algebra to reach a postulate-free ResourceAlgebra record with three instances under the stated flags within a week; records that it did so on day one and that the ruling is revisited if a family theorem proves unstateable under --without-K.

A rabbit reads the ruling by moonlight,
Then hops through types arranged just right.
Agda’s flags are noted in the tale,
While open questions mark the trail.
The register gains a link to follow,
And carrots wait in the burrow hollow.

🟡 Minor · Scope the PROVEN statuses to local results. · TYPE-CONNECTIONS.adoc:293-297

docs/TYPE-CONNECTIONS.adoc:293-297
📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Scope the PROVEN statuses to local results.

The register repeats cross-family arrows, but it does not state that PROVEN applies only to the cited fragment or result. This conflicts with the standing disclaimer and can lead readers to treat the arrows as proved bridges. Mark each status as local-only and state that the corresponding arrow remains conceptual until its bridge obligation is discharged.

Suggested fix
+The statuses below apply only to the cited local fragment or result. They do not prove the conceptual cross-family arrow or discharge any bridge obligation.
+
-| Resource Algebra → Choreographic | PROVEN (fragment) | K-CUT-LOSS parametric; needs only ⊕-idempotence and ⊗-left-unit.
-| Epistemic → Choreographic | PROVEN (fragment) | K-CUT-WARRANT bound and transport; Kripke frame over consistent cuts; SoundWarrant instantiated.
-| Tropical → Choreographic | PROVEN via MaxPlus instance | Lean provenance bridge (M-2) a review obligation.
-| Echo → Choreographic | PROVEN via Loss instance | RoleGraded base case recovered; import direction (L-2) open.
-| Occupancy → Choreographic | PROVEN (A-3) | Two-thread diamond: projections swap, occupancy does not.

Clarify the cross-family status register so each PROVEN label applies only to
its cited local fragment or result, not to the conceptual arrow. Add a brief
note stating that the arrows remain conceptual until their bridge obligations
are discharged, and qualify the Resource Algebra, Epistemic, Tropical, Echo, and

🟡 Minor · Scope the TINI proved statement or remove it. · TYPE-CONNECTIONS.adoc:299

docs/TYPE-CONNECTIONS.adoc:299
📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Scope the TINI proved statement or remove it.

The Secret Types boundary states that no noninterference theorem exists there. The register states TINI proved but names no theorem, repository, or scope. Readers cannot determine whether this reports Secret Types status or an external result.

Suggested fix
-| Secret → (none yet) | OPEN | TINI proved; the Echo reading of noninterference is a conjecture.
+| Secret → (none yet) | OPEN | No TINI theorem exists in Secret Types yet; the Echo reading of noninterference is a conjecture.
