# szl-formulas
**The 21 canonical SZL formulas — pure, typed, stdlib-only — as a `get_kernel`-discoverable offline governance kernel, each carrying its verbatim PROOF-STATUS.** From [SZL Holdings](https://huggingface.co/SZLHOLDINGS).

## Proof honesty (binding — Doctrine v11)
Two DISTINCT things, never conflated:
1. **Per-formula `PROOF_STATUS`** — mirrored **VERBATIM** from the canonical dataset, one of
`PROVEN / AXIOM / SORRY / CONJECTURE`. A `PROVEN(...)` tag here is an **obligation-level** label
(that narrow property is discharged in Lean or numerically exact) — it is **NOT** a claim that the
formula belongs to the locked-proven canonical set.
2. **`LOCKED_PROVEN_FORMULA_IDS`** — the locked-proven canonical set is **EXACTLY 8**:
`{F1, F4, F7, F11, F12, F18, F19, F22}`, machine-enforced by the **no-axiom** Lean theorem
`locked_count_eight` in [szl-holdings/lutar-lean](https://github.com/szl-holdings/lutar-lean)
(`PROVEN_FORMULAS.md`). This count is frozen at 8 and never inflated.
> The F-numbering is lutar-lean's own corpus (≥ 22 formulas). Its mapping onto these 21 registry
> entries is **NOT asserted here (UNKNOWN — never fabricated).**
## Quickstart (fully offline)
```python
from kernels import get_kernel
fx = get_kernel("SZLHOLDINGS/szl-formulas", revision="main", trust_remote_code=True)
print(fx.registry_count()) # 21
print(fx.lambda_aggregate([0.9, 0.8, 0.95])) # weighted geometric mean (D2)
print(fx.proof_status("madhava_series")) # "PROVEN(alternating series)" — verbatim
print(sorted(fx.LOCKED_PROVEN_FORMULA_IDS)) # exactly 8 F-ids
# governed loop: hash-chained receipts + 4 hard-stop validators
chain = fx.run_governed_loop([
{"formula_name": "lambda_bounded", "args": [[0.9, 0.8, 0.95]]},
{"formula_name": "reed_solomon_singleton", "args": [255, 223]},
])
print(chain["replay_ok"], chain["lambda_label"]) # True, ADVISORY (Conjecture 1)
print(fx.selfcheck()) # falsifiable_demonstrated: True
```
## The 21 canonical formulas
`lambda_aggregate` (Λ, weighted geo-mean D2), `lambda_homogeneous` (A2), `lambda_bounded` (A4),
`pac_bayes_mcallester`, `bekenstein_cascade`, `reidemeister_invariant`, `khipu_merkle_root`,
`dsse_envelope`, `gleason_quantum_lambda`, `hoeffding_tail`, `pinsker_kl_bound`, `fisher_rao_distance`,
`bohr_complementarity_floor`, `kochen_specker_18vector_witness`, `two_witness_ks18_soundness`,
`shor_codeword_distance`, `css_ingress_verify`, `kitaev_surface_correct`, `reed_solomon_singleton`,
`madhava_series`, `schur_concave_lambda_two_axis`. Each is pure, typed, no-I/O; call
`list_formulas()` for the name → verbatim PROOF-STATUS table.
## The governed-loop composer
`run_governed_loop(calls)` chains formula calls into hash-linked receipts; four HARD-STOP validators
gate every step — `state_transition`, `drift_bounds`, `human_gate`, `axis_floor` — and on **any**
failure the loop HALTS and the receipt chain seals at the last good step. `verify_chain` is a pure
replay verifier. **The Λ composition is ADVISORY only** (Λ = Conjecture 1); a high Λ is a
non-compensatory roll-up, **not** proven trust.
## Tests — MEASURED, local, stdlib-only
```
PYTHONPATH=build/torch-universal python3 -m pytest tests/ -q
17 passed
```
**17/17 passed** on a local `python3` run (MEASURED, stdlib-only). Every test is **FALSIFIABLE**: the
registry is exactly 21; the locked-proven set is exactly 8 (never inflated); `PROOF_STATUS` matches the
dataset verbatim and raises on unknown names (never coerced); Λ is a genuine weighted geo-mean (a zero
axis pins it to 0; a spread vector sits below the arithmetic mean); a clean governed loop replays but a
**tampered** receipt is detected and a sub-floor Λ **halts** the loop. `selfcheck()` reports
`falsifiable_demonstrated: True`.
