+= pons-asinorum vs panoply (2026-09-20)
+
+== What happened
+
+GitHub `hyperpolymath/pons-asinorum` **does** have an implementation
+(commit `ed2a3c46` M0+M1+M2: workspace, engine skeleton, T0 catalogue +
+falsifier). `crates/pons-cli` builds; `pons scan` runs.
+
+The **root README.adoc still says** “Planning complete; implementation
+not started.” That sentence is **stale**. That is why Phase 10 treated
+it as plan-only (#101).
+
+== What it actually scans
+
+T0 rules + tree-sitter for **Python, JavaScript/JSX, TypeScript/TSX,
+Rust only**. Panoply application code is Idris2 + Zig + Bash.
+
+Ran `pons scan` (release binary, 2026-09-20) on this tree: **zero
+findings**, exit 0 — expected, not a clean bill of health for Idris/Zig.
+
+== What is not done
+
+* Idris2 / Zig / Bash grammars
+* Dataflow / typestate (T1/T2) beyond the skeleton
+* README status line
+
+Issue **#101** remains open until either (a) pons covers this estate’s
+languages, or (b) we document N/A and close as “scanner not applicable
+yet”. Prefer (a). Do not close charter issues on an empty scan.

+These ids are **named contracts with empty earned sets**. There is no
+codegen, no bitstream, no CUDA/ROCm kernel, no QASM. A Core program
+lowered here (when lowering exists) **refuses** until a named guarantee
+has a check/proof/runtime means.

+== Means (all absent)
+
+* Check: none (no Core checker, no ISA verifier).
+* Proof: none (no preservation theorem for any class).
+* Runtime discipline: none (no driver contract, no device fence).
+
+== Cannot uphold (all classes)
+
+Total-correctness, Core typing, memory-safety of Idris values, timing
+side-channel freedom, quantum correctness, FPGA timing closure,
+cross-vendor portability.
+
+== Emitter
+
+`scripts/emit-manifest.sh <id>` must refuse (`:earned` empty) for every
+id above until that class has a lowering. Default remains `none`.
+
+== Gate to leave this catalogue
+
+A class leaves “nothing” only when: (1) Core checker exists, (2) a
+lowering preserves a *named* guarantee, (3) tests fire on a refused
+program and pass on an accepted one. Until then issue **#9 stays open**.
