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.
