The notebook form refused an integer beyond 2^53-1 with 'L' is N, beyond the +-9007199254740991 the form can hold exactly: type a smaller number, .... Spec 6.2 (vectors NUM-02, NUM-03) asks for the worker templates, which conformance.json carries as messages.number_above_maximum and number_below_minimum. Now the form says:

• above: 'L' must be <= 9007199254740991
• below: 'L' must be >= -9007199254740991

where L is the field's label. Nothing else changes: code invalid_parameter, the value is never changed or clamped, no run starts, the tooltip (Whole numbers up to +-N.) is untouched. Only ToolForm.values in labconstrictor_tools/notebook.py changes (the old single abs(value) > check becomes two checks, one per template).

Tests

• tests/test_notebook_unset_and_range.py: test_NUM_02_and_NUM_03_use_the_sentences_of_the_spec_and_start_no_run takes the vectors and templates from conformance.json (typed values and the sentence in the vector's expect), goes through ToolForm.run() and checks the status text exactly, that the tool never ran, that the control keeps the typed value, and values() raises the same message; test_NUM_01_the_largest_exact_integer_is_sent_unchanged covers the accepted edge. The older test (MAX+1 refused, MAX accepted) still passes.
• tests/test_sabotage.py: four rows notebook form: ... (old sentence, lost minus sign, >= instead of >, negative limit moved).
• docs/REGRESSION_LEDGER.md: one row (2026-10-12), inserted after the F4 row (not at the end of the table, to stay clear of other PRs).
• docs/CONFORMANCE.md: Gaps item 6 (this divergence) removed; the other numbers are unchanged on purpose.

black, ruff, mypy, vulture clean; relevant tests and the sabotage rows pass.

Local full suite as the non-root user tester, private TMPDIR (cleaned up afterwards): all tests pass except 2 in test_tools_features (test_register_writes_them_into_the_entry_and_the_cached_schema, test_doctor_prints_them_and_does_not_call_an_upgrade_stale). Those fail only in this sandbox, unrelated to this PR: the app interpreter /usr/bin/python imports an old editable install of Tools from /tmp/wt_versions (no retention_prune feature). CI is green on every job.
