Verification records for L22

../

clean_gate/: The non-author clean gate of 2026-10-13 for L22, one run serving L17, L20, L21 and L22: the committed Lean gate in clean mode over a fresh archive of the whole lean/ tree as it stood on 2026-10-13T04:56:43Z, exit 0, AUDIT PASS over 4 claims with 0 compiler axioms and the committed self-test stamp matched; the receipt, the captured log and the wrapper.

clean_gate_2/: The non-author clean gate of 2026-10-13 for L22 on Lean v4.34.1, one run serving L20, L21 and L22: the committed Lean gate in clean mode over a fresh archive of the whole lean/ tree of the change that ported their Lean modules to Lean v4.34.1, as committed at 2026-10-13T19:38:30Z, exit 0, AUDIT PASS over 4 claims with 0 compiler axioms and the committed self-test stamp matched; the receipt, the captured log and the wrapper.

statement_fidelity/: The independent statement-fidelity audit of Erdos.L22.statement against the L22 card's prose statement as it stood on 2026-09-28, verdict PASS, its distinct grade, pass with tier 2 asserted, and the non-author clean-gate receipt, log and wrapper that put the tier in force.


The statement-fidelity record, statement_fidelity/, holds the independent whole-statement fidelity audit of Erdos.L22.statement against the prose statement of L22 as it stood on the default branch at 2026-09-28T13:50:48Z, verdict PASS, the distinct grade of that audit, pass with tier 2 asserted, dated 2026-09-28, and the non-author clean-gate receipt of 2026-09-29 with the gate's captured log and the runner's wrapper. It is the first record for L22. The grade's assertion is in force from the promotion that cites it together with the clean gate; the acceptance is kernel-only, with zero compiler axioms admitted, and is of that source alone. One run of the gate serves the five claims whose statement-fidelity records name that source, L18 to L22, each filing the receipt with its own owner and manifest row and byte-identical copies of the log and the wrapper; the run was made by a non-author clean-gate runner in a fresh context and filed by the integrator of the promotion, who asserts no tier. No native binding or acceptance warrant is filed; these records use neither. The second record, clean_gate_2/, holds no fidelity audit: it is the non-author clean gate of 2026-10-13 over the whole lean/ tree of the change that ported the Lean modules of L20, L21 and L22 to Lean v4.34.1, as committed at 2026-10-13T19:38:30Z (exit 0, AUDIT PASS over 4 claims with 0 compiler axioms, the self-test stamp matched), one run serving L20, L21 and L22, to whose tree the card's standing binds the warrant. The earlier clean gate of 2026-10-13 holds the same for the whole lean/ tree as it stood on 2026-10-13T04:56:43Z, on Lean v4.32.0-rc1, one run serving L17, L20, L21 and L22.
