From f3dbcbfd8f89ede2c9a6913c58829355c3fdaef6 Mon Sep 17 00:00:00 2001 From: "Jonathan D.A. Jewell" <6759885+hyperpolymath@users.noreply.github.com> Date: Wed, 5 Aug 2026 10:22:52 +0100 Subject: [PATCH 1/5] chore: fill derivable placeholders, drop false ARCHITECTURE, surface the rest MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Estate top-up pass. Three separate things, none of which invents a value. FILLED — every token with a single mechanical answer: OWNER, REPO, FORGE, PROJECT, PACKAGE_NAME, PROJECT_NAME, AUTHOR, AUTHOR_EMAIL, CONDUCT_EMAIL, AUTHOR_FIRST/LAST/INITIALS, CURRENT_YEAR, CURRENT_DATE, DATE, MAIN_BRANCH. Identity comes from the git remote, dates from the clock, project name from the README H1 where there is one. Deliberately NOT filled, because more than one defensible answer exists and a confident wrong value is worse than a visible gap: SECURITY_EMAIL (two competing addresses are in use across the estate), RESPONSE_TIME, CONDUCT_TEAM (which substitutes into "a {{CONDUCT_TEAM}} member", not English), WEBSITE, PROJECT_DESCRIPTION, LANG_STACK. DELETED — ARCHITECTURE.md, where it is byte-identical to the 346-copy estate boilerplate (blob 607e3d8c). Those 33 lines describe a src/ tests/ docs/ scripts/ config/ tree that this repo does not have, so the file is not merely uninformative, it is wrong. Genuinely written ARCHITECTURE files are matched by hash and left alone. No file beats a confidently false one. CODEOWNERS — rewritten to the solo form mandated by hyperpolymath/standards CODEOWNERS-POLICY.adoc Rule 1, which forbids a catch-all line where the only owner is the sole maintainer. The estate's own templates/CODEOWNERS contradicts that policy; the policy is versioned, dated and resolves standards#55, so it wins. Files naming a genuine co-owner are Rule 2 and are untouched. Note @hyperpolymath and @metadatastician are the same person, so a file naming the other account is a copy artifact that silently routed review requests to the wrong account. SURFACED — REQUIRES_INITIALISATION.md, and a priority action in 0-AI-MANIFEST.a2ml. Tokens that need a decision no script can make are left visibly unfilled rather than faked or quietly deleted. The marker says what each one is, which files it belongs in, why it was not done already, and that it must be deleted only once the work is genuinely finished. --- .github/CODEOWNERS | 36 ++----------- .../bot_directives/methodology.a2ml | 2 +- 0-AI-MANIFEST.a2ml | 17 ++++++ ARCHITECTURE.md | 47 ---------------- REQUIRES_INITIALISATION.md | 54 +++++++++++++++++++ 5 files changed, 75 insertions(+), 81 deletions(-) delete mode 100644 ARCHITECTURE.md create mode 100644 REQUIRES_INITIALISATION.md diff --git a/.github/CODEOWNERS b/.github/CODEOWNERS index 3a3b7f2..4714ad5 100644 --- a/.github/CODEOWNERS +++ b/.github/CODEOWNERS @@ -1,34 +1,4 @@ # SPDX-License-Identifier: MPL-2.0 -# CODEOWNERS - Define code review assignments for GitHub -# See: https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-code-owners - -# Default: sole maintainer for all files -* @hyperpolymath - -# Security-sensitive files require explicit ownership -SECURITY.md @hyperpolymath -.github/workflows/ @hyperpolymath -.machine_readable/ @hyperpolymath -contractiles/ @hyperpolymath - -# License files -LICENSE @hyperpolymath -LICENSES/ @hyperpolymath - -# Configuration -.gitignore @hyperpolymath -.github/ @hyperpolymath - -# Documentation -README* @hyperpolymath -CONTRIBUTING* @hyperpolymath -CODE_OF_CONDUCT* @hyperpolymath -GOVERNANCE* @hyperpolymath -MAINTAINERS* @hyperpolymath -CHANGELOG* @hyperpolymath -ROADMAP* @hyperpolymath - -# Build and CI -Justfile @hyperpolymath -Makefile @hyperpolymath -*.sh @hyperpolymath +# Solo-maintained hyperpolymath repo: no owner lines by policy. +# See hyperpolymath/standards CODEOWNERS-POLICY.adoc (Rule 1). +# Sole-maintainer review is moot; SPDX headers carry attribution. diff --git a/.machine_readable/bot_directives/methodology.a2ml b/.machine_readable/bot_directives/methodology.a2ml index 754f357..cedb5bb 100644 --- a/.machine_readable/bot_directives/methodology.a2ml +++ b/.machine_readable/bot_directives/methodology.a2ml @@ -101,7 +101,7 @@ constraints = [ # These rules detect corrupt/template/stale state files.

This line is a DETECTOR list: the comment above it says these rules detect corrupt/template/stale state files, so the tokens named in it are the ones whose PRESENCE means a state file is broken. Substituting it did two things. It blinded the {{PROJECT}} leak detector, and it made the detector reject any state file containing this repo's own uppercased name — the opposite of what the rule is for. Same failure class as a template recipe rewriting the incident record that documents its own bug: substituting tokens inside a thing that is ABOUT tokens. Nothing else in this PR changes.
