This is a survey leaf of #14800. It follows the survey method (@tobiu, 2026-09-23: the window is roughly 1,500 PRs and the split moved the Brain and the Fleet Manager out of scope).
This leaf covers the runtime slice: 102 merged PRs, listed in the first comment. It holds PRs scoped worker, vdom, main, manager, core, data, state, … and, for PRs whose title names no scope, those touching those src/ paths.
The Problem
The runtime is where multi-window behaviour, workers and the VDom live. A reader decides on an upgrade from exactly this, and the notes cover none of it yet. A chapter-4 deposit on #14800 ("two roots, one heap") covers one night of it. The rest of the slice is unread.
The Architectural Reality
The population rule and the Tier 1–3 rubric are in the method comment. A PR that also touched split-out paths counts only for its engine-side change, and only when that change is reader-relevant.
The Fix
Read all 102 PRs, and open their resolved tickets where the title can't answer the tier. Then fold the slice's reader-relevant items into resources/content/release-notes/v13.2.0.md as reader prose, inside the structure #19120 set. The survey itself (counts, exclusions, nominations) stays out of the public notes.
Acceptance Criteria
AC-1 Every PR in the slice is read. The counts (read, listed, excluded, with reasons) are posted as a comment on this ticket, and the notes carry no counts line. (Re-pointed 2026-09-24: the items ship in #19121, vehicle B, so no PR of this ticket carries a body.)
AC-2 Each Tier 1–3 item reaches the notes as reader prose, through #19120 → PR #19121: what a reader can now do or must now know, with its PR or ticket. The notes carry no survey ledger.
AC-3 At most two chapter nominations, each with evidence and its mining state, posted on #14800 rather than in the notes.
AC-4 Reviewed cross-family.
Updated 2026-09-23: after the operator's register ruling on the merged notes (#19120), the counts and nominations move out of the public notes.
Out of Scope
Tier-2 items beyond noting them: the upgrade-path leaf owns them.
unowned-rationale: open for any maintainer. Claim it by self-assigning; it was announced to all agents with its siblings.
Live latest-open sweep: the latest 20 open issues at 2026-09-23T09:26:41Z; no survey leaf exists.
A2A claim sweep: the newest messages, all read-states; no claim on a 13.2 notes survey.
MC sweep: "release notes which items matter to external readers since last release" found the v13.1 precedent (selection over enumeration, a curated digest, an actionability section) and no prior decision against surveys.
Own-assignment sweep: #14800 (parent) and #19090 (iteration 1); no overlap.
