From af1e59d8cb5d8eaaebe73a11132cdadad902886f Mon Sep 17 00:00:00 2001 From: "Jonathan D.A. Jewell" <6759885+hyperpolymath@users.noreply.github.com> Date: Mon, 14 Sep 2026 22:20:34 +0100 Subject: [PATCH] feat(taxonomy): ratify Categories 17 and 18; fix the 16x14 arithmetic MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ⚠ PRE-COMMIT HOOKS BYPASSED (--no-verify). Disclosed, not hidden. Two of the eight .githooks validators reject this commit, both because they test for a comment prefix their inputs do not use. Measured on this tree: validate-a2ml.sh tests ^# SPDX / ^version: / ^agent-id:|^pedigree: -- a YAML dialect. Actual population: 207 TOML-ish, 15 S-expression, 0 YAML. PASS RATE: 0 of 222. validate-spdx.sh tests ^# SPDX-License-Identifier: against staged files with NO extension filter, so it checks .adoc, which comments with //. All 1,046 tracked .adoc files fail; 231 of them carry a correct // SPDX header. Staged-mode pass rate: 687 of 2,610 tracked files. A gate that admits nothing discriminates nothing. These two are the mirror of the always-green gate -- vacuous in the other direction -- and neither is run by any workflow (`git grep validate-a2ml -- .github/` is empty), so CI is unaffected either way. The other SIX validators were run individually against this exact file set and all pass: k9, spdx-workflows, sha-pins, permissions, codeql, bot-directives. Nothing else is being skipped. This commit message was also checked against .githooks/commit-msg by hand, since --no-verify skips that hook too. The validators are NOT repaired here -- that is someone else's live campaign (.githooks/ is being edited concurrently) and exceeds R-33/R-34. Filed as standards#791, which also records a third symptom found while measuring: the scan-mode allowlist names .rs .js .zig .ex .ml .adb .ads .json, none of which can legally begin a line with "# ", so 128 files in its own declared scope are unsatisfiable by construction. A concurrent session already has an unlanded fix for the staged/scan mode split; #791 references it rather than duplicating it. WHAT CHANGES TESTING-TAXONOMY.adoc gains two full normative sections before Part II, matching the other sixteen in depth and shape (Definition / Purpose / Tools / Applies to): === 17. Type-Safe Tests Negative witnesses in compiler-checked `failing` blocks. Nine subcategories (Tropical, Epistemic, Choreographic, Dependent, Effects, Decorative, Ceremonial, Dyadic, EchoTypes). Closes with: "Pin the error text, not merely the failure." === 18. Coupling / Drift-freedom Tests Artefacts that must agree where nothing forces them to. Carries a "Relationship to Part VI" paragraph tying it to CR-1/CR-2/CR-9 as the cross-repo instances of the same shape. Closes with: "The strongest form deletes rather than reconciles." Discharges owner rulings R-32, R-33 and R-34, and unblocks proven-tests-and-benchmarks issue #46 item D4, open since 2026-08-27 and explicitly awaiting an owner ruling. NUMBERING RATIONALE (R-32) TypeSafeTest is ratified at 17 and Coupling/Drift-freedom takes 18, rather than the reverse. TypeSafeTest has already shipped in ptb's Types.idr since before this campaign. Numbering it 17 means zero renumbering of shipped code, no migration note, and no already-serialised artefact -- run reports, ladder files, .a2ml manifests, VeriSimDB rows -- changes meaning. The cost is this file's own weak-points bullet, which proposed Coupling as 17; it is marked RESOLVED in place with the original proposal text quoted verbatim, so the amendment is visible rather than silently overwritten. THE ARITHMETIC (R-33) R-33 named two lines. A sweep found SIX, in three different spellings -- one count asserted in six uncoupled places, which is itself a Category 18 defect in the document that defines Category 18. All six are corrected: TOOLCHAIN-READINESS-GRADES.adoc:78 16 -> 18 (four-axis formula) TOOLCHAIN-READINESS-GRADES.adoc:268 16 -> 18, and gains the full four-axis formula, resolving its self-contradiction with line 78 README.adoc:98 16x14 -> 18x14 SELF-ASSESSMENT.adoc:94 16 x 14 -> 18 x 14 TOOLCHAIN-READINESS-GRADES.a2ml:64 16x14 -> 18x14 TOOLCHAIN-READINESS-GRADES.a2ml:65 16x14 -> 18x14 TWO FURTHER SITES FOUND BEYOND THE SIX Appendix A gains two rows -- Type-Safe (TSF) and Coupling/Drift-freedom (CDF), both graded C+ -- taking the table from 16 rows to 18. Appendix C:829 is DELIBERATELY NOT changed to 18. It records a K9 assessment made before these categories existed. Inflating it would manufacture coverage that was never assessed. It is annotated instead to say it reflects the categories that existed at the time of assessment, and that K9 has not yet been reassessed against 17 and 18. NO GATE CHECKS THESE FIGURES Disclosed plainly: nothing in CI verifies this arithmetic. The six sites drifted precisely because no gate couples them. A grep-based gate would need three patterns to cover the spelling variance (`16 categories`, `16 x 14`, `16x14`). That gate is a follow-on, not part of this change; until it exists these figures are held in agreement by discipline alone. The .a2ml file's EXTENSION is deliberately untouched. Renaming .a2ml -> .deed waits on dual-accept validators; the last estate rename broke 122 gates. Only the arithmetic inside it changes.
