The changelog said nothing had been released since 1.0.0. Twenty-two builds had shipped. Twenty-one entries sat under "## Unreleased" in a file with exactly two headings, so a reader at any tag found no section for the version they were holding. Which release carried which entry is DERIVED, not guessed: for every line in the region, the commit that introduced it, then the earliest tag containing that commit. That yields seven releases - .22, .21, .20, .19, .14, .8 and .0. No entry text changed. A verification pass compares the multiset of non-heading lines before and after and refuses to write if anything was lost, gained or duplicated; entries move under their release, so it compares as a multiset rather than in order. CHANGELOG.txt was kept BY HAND and drifted the moment the .md was reorganised, which is the failure the plain-text-twin rule exists to prevent. readme_txt.py becomes plaintext_twins.py and renders every pair. It also drops <!-- --> markers, invisible in markdown and stray punctuation in a text file - that is the whole of README.txt's diff. The --check that keeps twins honest was never run. readme_txt.py shipped one and its docstring claimed "the test suite runs --check"; nothing invoked it, so a twin could disagree with its markdown indefinitely. tests/PlainTextTwins.Tests.ps1 runs it. That test skipped on its first run while claiming to pass: -Skip is evaluated during DISCOVERY, before BeforeAll, so the python lookup left the flag $null. Resolved in BeforeDiscovery, and when python really is absent the result is INCONCLUSIVE rather than a green tick for a check that never happened. Mutation-checked: appending one line to CHANGELOG.txt fails "every twin is in sync with its markdown", and only that test. tests: 243 passed, 0 failed, 1 skipped (the no-python reporter, correctly).
