@ -86,6 +86,37 @@ edges rather than merely appending membership at the sink. It follows that
every `ready` issue is a gate member. `epic` and `post-merge` issues are exempt
because neither is claimable (#292).
A member that lands `post-merge` releases nothing: that exemption is about
claimability, while a `post-merge` issue is still open and an open predecessor
holds its successors, so every successor declaring on it stays held and the
window stops advancing along that edge (#329).
**When a member reaches `post-merge` and any open declaration names it, triage
splits the remainder**: mint a fresh issue carrying the outstanding criteria
verbatim, naming its owner and its wake condition and citing the original, then
close the original on what it delivered. Triage owns this because only triage
mints issues and `post-merge` is its completion queue (#329).
**The release edge is the original's close, never the remainder's.** Each
successor's declaration names the original's number, so closing the new issue
releases nothing (#329).
**Split only when an open declaration names the issue.** The trigger is a check
rather than a judgement — run the blocker parse over every open `blocked` body
and see whether this number appears — because an issue that strands nothing is
`post-merge` working as intended (#329).
**Never close work out from under a builder.** Where the original is assigned,
`claimed`, or carrying an open PR, amend its body to hand the outstanding
criteria to the new issue and let its holder close it, so the release edge above
is reached without taking the work from them (#329).
**Do not instead teach the blocker parse that `post-merge` counts as landed.**
That promotes a successor while its predecessor still owes acceptance criteria,
inverts a parser whose deliberate error direction is to hold or flag a reference
it cannot read rather than release it, and needs label data a reference-state
lookup does not carry (#329).
The operator may declare a parallel track at init when its footprint is
disjoint from the primary window: another repository, another artifact, or
provably non-overlapping clusters. The declaration names the boundary and any
