Three issues named the branch that fixed them, and a branch is deleted
when it merges — so every `fixed-by:` was a pointer that resolved to
nothing by the time anyone followed it. They name commits and pull
requests now, and playbook 03 says to.
Two records were missing the thing a reader arrives for. 146 did not say
that one of its fixes crash-looped the control plane on a running mesh,
which is the whole reason the delivery subject carries the stream and the
raise path was the only one exercised. 151 did not say that 152 removed
the false reasons its roster moved, or that it stays open for the real
ones.
ADR 0080 enumerates what cycle.py enforces and named four things; it
enforces five. A progressive insight names the fifth — the decision
stands, the list had gone stale. The checks README and playbook 03 gained
the same rule, and 155 points at all three.
Two machines filing issues in the same hour both read main correctly and
both took "the next free number". main lags every open pull request —
seven that evening — so they collided twice. The second collision
reached main with records, cycle and index all reporting success.
cycle.py now refuses a tree where two issue folders share a leading
number, and names both. Proven by adding a duplicate and watching it
fail. The colliding records become 153 and 154, renumbered in the branch
that lands last, because renumbering a branch whose author is still
pushing only moves the race.
The check catches a collision; it does not prevent one. Taking a number
still means reading the open pull requests as well as main — issue 155
says so.
