ADR 0201 → 0202, and three issues from the night it shipped

The derived-value record is renumbered a second time: the key-value-buckets
record took 0201 while this waited to merge, as the bundles record took 0188
before it. Both times free when chosen, taken by the time it landed. cycle.py
caught it; three repositories cite this record, so the number matters.

225 — a provisioner has not been able to read its grant secrets since 01:30,
when a module's own code left its container and the files stayed root's. Four
thousand refusals, each worded as patience, and two consumers unserved. Not
from ADR 0202 or 0189, which landed hours later; dates in the report.

226 — the store's sweep stops at the first reference recorded with an address
and collects nothing. A guard that cannot tell 'I will not ask about this'
from 'it would not answer' stops the wrong amount of work.

227 — the photo app's admin client asks for the port the proxy holds. A module
pinned months behind carries everything its branch gained, the first time
anything makes it move.
