fix(affirmation-check): make the gate ask the standard's question, and able to fail - #806

Conversation
The gate searched the repo root only, so an affirmation at
docs/AFFIRMATION.adoc -- a location AFFIRMATION-STANDARD.adoc explicitly
permits, and the one the canonical rsr-template-repo skeleton actually
ships in -- was reported as missing. It also accepted AFFIRMATION.md,
which the standard bans ("as README.md is banned"), and had no exemption
for template repositories, whose affirmations carry {{...}} placeholders
by design.
- search ./AFFIRMATION.adoc then ./docs/AFFIRMATION.adoc
- reject AFFIRMATION.md (and the extensionless spelling) with an error
naming the rename, rather than silently accepting it
- add is-template, defaulted from the repository's own is_template flag,
so template repos are exempt without per-repo configuration
- treat unreplaced <full 40-character SHA> / <ISO-8601> / <YYYY-MM-DD>
anchor fields as placeholders too
Controls: test.sh grows three defect-named controls. Run against the
previous check.sh each one fails -- docs/ reported absent, AFFIRMATION.md
accepted, template placeholders rejected -- so the suite demonstrably
detects the defects rather than merely passing.
Note: this action was untracked and referenced by no workflow, so nothing
was failing in CI; the defect was latent, not live.

The gate initialised its signature variable to `N` as a "nothing to report"
sentinel. `N` is also what `git log --format=%G?` returns for a commit that
carries NO signature at all. So three different states shared one arm:
- the working tree is not a Git repository (no reading possible)
- Git is present, the file is not in history (shallow checkout)
- Git read the commit and it is UNSIGNED (a measured verdict)
All three fell through to `*)` and emitted `::notice::`. A notice cannot fail
a job, so an unsigned affirmation passed a gate whose entire purpose is to
establish that the affirmation is signed -- and AFFIRMATION-STANDARD.adoc's
own worked example is `git commit -S -s docs/AFFIRMATION.adoc`. This is the
self-refuting outcome the standard warns about, produced by the gate meant to
prevent it.
The three states are now distinct, because exactly one of them is unknowable:
`unavailable` and the empty reading stay notices (honest limitations of the
checkout), while `N` is a hard error. `X`/`Y` (valid but expired signature or
key) are named explicitly as warnings rather than being swallowed by the
catch-all, and the catch-all itself now FAILS CLOSED: a governance gate must
not pass a status it cannot interpret.
Controls: the suite grows three, and they were verified against the previous
revision before being trusted.
- "UNSIGNED affirmation commit is rejected" -- run against the old check.sh
this control PASSES the gate and so FAILS the suite (measured: 11 ok, then
this one FAIL). That is what makes it a control and not a decoration.
- "uncommitted affirmation is indeterminate, not fatal" -- pins the shallow
-checkout case open, so the fix cannot be mistaken for "signature reading
absent => fail".
- "signed affirmation commit passes" -- the positive control. A suite that
only proves a gate can fail would be satisfied by a gate that rejects
everything. It generates its own throwaway ed25519 signing key and
allowed-signers file, so it needs no external secret and commits no key
material; it then asserts the fixture really produced %G? == G before
relying on it, so it cannot pass for the wrong reason.
shellcheck is clean on check.sh.

What
Adds the
affirmation-checkcomposite action, and fixes the defect that made itssignature check unable to fail.
The signature defect
The gate initialised its signature variable to
Nas a "nothing to report"sentinel.
Nis also whatgit log --format=%G?returns for a commitcarrying no signature at all. Three different states therefore shared one arm:
All three fell through to
*)and emitted::notice::. A notice cannot fail ajob, so an unsigned affirmation passed a gate that exists to establish the
affirmation is signed — while
AFFIRMATION-STANDARD.adoc's own worked exampleis
git commit -S -s docs/AFFIRMATION.adoc. That is precisely the self-refutingoutcome the standard warns about, produced by the gate meant to prevent it.
After
The three states are separated, because exactly one of them is unknowable.
unavailableand the empty reading remain notices (honest limitations of thecheckout, not findings about the commit);
Nis a hard error.X/Y(valid signature, expired signature or key) are named explicitly as warnings
instead of being swallowed. The catch-all now fails closed — a governance
gate must not pass a status it cannot interpret.
Controls, verified against the previous revision
The suite grows three controls, and they were run against the old
check.shbefore being trusted:
The mutant-killer fails on the old script and passes on the new one. A control
that cannot fail against a broken gate proves nothing.
The positive control matters as much: a suite that only proves a gate can
fail would be satisfied by a gate that rejects everything.
signed affirmation commit passesgenerates its own throwaway ed25519 key and allowed-signers file— so it needs no external secret and commits no key material — then asserts the
fixture really produced
%G? == Gbefore relying on it, so it cannot pass forthe wrong reason.
13/13 pass.
shellcheckis clean oncheck.sh.Blast radius
None today. This action is referenced by no workflow, so nothing was failing
in CI and nothing starts failing on merge — the defect was latent, not live.
Tightening
Nto an error is therefore free now and correct later, which is whyit is done now rather than deferred until repos depend on it.
Also in this branch (earlier commit)
0c98438makes the gate ask the standard's question: search./AFFIRMATION.adocthen
./docs/AFFIRMATION.adoc(the canonicalrsr-template-reposkeleton shipsin
docs/, so a root-only search reported a present affirmation as missing);reject the banned
.mdspelling with an error naming the rename; exempt templaterepositories, whose affirmations carry placeholders by design.
