Restores something the specimen said and the round that discarded the specimen
lost with it: a changed external becomes a polad in the cart, and somebody
decides. check now stages what moved into .loom/cart/current/polad/ with the ETag
that was served alongside the bytes, and prints the .usages.md beside it, because
reconciliation runs the other way — the facets usually survive and what moves is
the code a usage named. It says so when there is no usages file, which is its own
finding.
With no cart open, check reports and stages nothing. The tool does not open a
round: a cart is a bounded exchange between two presences and starting one is
somebody's act, not a side effect of asking about freshness.
add now adopts what is not here and refuses what is already adopted, superseding
the entry that had it announce an overwrite — it no longer overwrites at all. The
one exception is the only way out of a dead end: a document present but unlocked
was fetched by hand, nothing records its origin, and the path does not round-trip,
so check cannot ask about it and a refusal would strand it forever. add accepts it
and the bytes decide — identical locks it without rewriting anything, which makes
the lock's assertion verified rather than assumed, and different stages a polad and
leaves the local copy alone because it is the only evidence anything moved.
apply exists because the lock is the half a person forgets: moving a polad by hand
leaves a lock describing the copy you just replaced. Recorded with its limit —
for an external, discard does not mean the change goes away, so discarding is
really knowingly stale and nothing yet records that choice.
Measured end to end on this repository: eight hand-fetched documents, all eight
locked, nothing rewritten.
