a facet describes the local pair; and this repository gets a log

Two decisions from cart osprey in loom-cli, and this repository had nowhere to
record them until now.

404 is named as two answers wearing one status, filed as a gap using this
document's own test and correctly ours to close.

And the correction that matters: a facet describes the local pair. A gap is true
of the copy you hold rather than the document upstream, so a publisher fixing
their end does not close it — we nearly deleted a consumer's .gaps.md on exactly
that mistake. It follows from the thing this convention rests on, that the copy
is theirs and everything beside it is ours, which we had not followed through to
reconciliation. A gap closes at reconciliation, not at repair.

With the consequence we would not have reached: what survives is not the gap but
what the gap justified. A workaround is often not retired by a fix — it stops
being a workaround and becomes specified behaviour, unchanged in code and
entirely changed in status, which is invisible where the code is and therefore an
entry in the consumer's own log. And a closed gap is not a decline: opposite
sign, and filing one as the other puts a thing you wanted into a list of things
you rejected.
