Read the answers that landed rather than the questions they replaced

What was wrong

Every entry of the plan's question issue was answered on 2026-08-24, eight
decision records landed for the eight answers, and two documents went on
describing entries of it as open.

docs/promotion.md was the one that cost something. It told a reader:

Entry three of issue #46 asks who may place a contributor's work under another
board's terms and carries no answer, so a hand-over of somebody else's work
still cannot be completed, and writing anything else into this line would be
inventing permission nobody gave.

Record 0020 answers exactly that question, is on the default branch, and says
of itself that the answer reaches this checklist and that the section gains a
fifth thing. It had not:

grep -c -i 'consent' docs/promotion.md
0

So the document refused a hand-over that the recorded decision permits.

What the change does

The checklist gains the consent item: what it is, when it is asked for, when it
is not, and that it is written as a Consent: line in the promotion section.

It is added together with what does not stand behind it. Nothing in this
repository refuses a promotion section that names no consent, because the check
holds the section to the four things record 0005 names and adding a fifth is a
record-format change under record 0013. Record 0020 states that residual and
the checklist now carries it too, because an item a reader takes for enforced is
worse than one they can see is owed.

docs/supply-chain.md rested three triage rows on the same entries. The
Contributors row called who may contribute an open question, which record
0024 answers. The Packaging and Signed-Releases rows rested on whether this
board publishes artefacts at all, which record 0021 answers, and Packaging
named a permanent -1 as the correct outcome on a branch that can no longer be
taken.

No re-score was run. Nothing here claims a score moved, and both rows now say to
re-read them against a scored run once a release exists.

What this does not finish

#216. One site is left and it is a question rather than an edit:
docs/decisions/0012-the-supported-platforms.md states the entry is open, and
record 0000 says a landed record takes exactly one edit, the line naming what
superseded it. What repairs a landed record carrying a claim that has stopped
reproducing is a rule nobody here has taken, and taking it inside this change
would be worse than leaving three words in place. The issue carries it.

Two sites named in that issue are deliberately untouched because neither is
wrong: 0001 and 0005 say an entry is not decided in the record carrying the
sentence, which is a statement about that record's own scope and is still true.

A defect found on the way and not repaired here

The two existing links in docs/promotion.md are written relative to the
repository root and do not resolve from a file inside docs/:

grep -n '](docs/decisions/' docs/promotion.md
10:[docs/decisions/0005-how-a-result-leaves.md](docs/decisions/0005-how-a-result-leaves.md),
39:[docs/decisions/0018-the-licence-of-this-board.md](docs/decisions/0018-the-licence-of-this-board.md)

docs/operator-guide.md and docs/privacy.md write theirs relative to docs/,
and the two links added here follow them. Repairing the other two is a different
topic from this change and it is written into the issue rather than done here.

The means

Markdown prose in two documents that already exist, because what is wrong is what
those documents say. Nothing here adds a language, a runtime or a dependency.
Whether a document describes an answered question as open is a judgement about
meaning that no reading of this tree makes, so no check is owed for it and none
is added.

The gate, run at this head

go build ./cmd/... ./internal/...
go vet ./cmd/... ./internal/...
gofmt -l cmd internal
go test -count=1 ./cmd/... ./internal/...
go run ./cmd/lab check .

Every one silent or green; gofmt -l printed nothing, which is its passing
result. All thirteen packages returned ok, and the runner's own verb:

examined .
1 experiment directory walked, 1 record read
26 decision records read
0 refused

Reading

There is no second reader for this change tonight. The evidence above stands in
place of one rather than replacing it.
