v2026.10.0

What's Changed

• install.sh installs the whole bundle, so the installation it leaves verifies by @jjstwerff in #1364
• Three streams joined: 37 issues (#1361–#1399), and a native cache race that made the gate red by @jjstwerff in #1400
• 56 issues, 23 deviations closed: the null model, tuples, closure lifetime, and @PLN157's consumer lane by @jjstwerff in #1465
• Three streams joined: 18 issues, 7 deviations, and the native arc from 104x to 2.6x on its simplest row by @jjstwerff in #1480
• Four streams joined: nine issues, three deviations, and the capture that was never a whole value by @jjstwerff in #1490
• (F-Block) at three levels, install integrity, and eight issues closed by @jjstwerff in #1502
• Fourteen issues and four heap deviations: a resource is released once, at the record's death by @jjstwerff in #1516
• A release is a fact per path: three (O-Complete) issues, the ownership register back to zero by @jjstwerff in #1518
• Five issues and @PLN157's native arc: a displaced free asks the container it came from by @jjstwerff in #1524
• Nine issues, @PLN162's multiple dispatch, and @PLN157 through § V-an: a tuple member write is a field write by @jjstwerff in #1533
• const reaches only const (C124, #1540), @PLN162–165, and the sibling joins by @jjstwerff in #1542
• The advisory gates close, the gallery runs, and @PLN164 joins through C5 by @jjstwerff in #1547
• The loft2/157 join, @PLN164 through E-1, and D-heap-13 measured rather than cured by @jjstwerff in #1555
• @PLN157/@PLN164: the drawing pass within 4x of Rust, and eight issues closed by @jjstwerff in #1560
• Today's four lines joined: @PLN158 W1-W2, @PLN165 E1-E4, the release fixes, and @PLN167 A0-B3 by @jjstwerff in #1608
• @PLN167 A0-A2: a & link reaches a narrow local at its own width, and three silent-wrong defects on the way by @jjstwerff in #1632
• C127: a declared narrow range has no null — plus the comparison subjects, four joins and five fixes by @jjstwerff in #1644
• Five sibling lines joined, and the release checks re-cut: a gate that can end in evidence by @jjstwerff in #1654
• The release is proven against its consumers: release.yml calls consumer-main-health at the tag by @jjstwerff in #1655
• Four lines joined: @PLN167 finished, #1647's regression and #1651 fixed, and the derived rows re-measured by @jjstwerff in #1661
• Four lines joined: copy leases on every path, eight issues fixed, the Windows leg inside its limits by @jjstwerff in #1667
• Three lines joined again: #1670 linked-vector stride, #1664/#1648/#1668/#1669/#1671, a native generation memo, and the nightly reds by @jjstwerff in #1672
• Six plans closed; loft2 + loft3 + 157-native-4x joined (#1673, #1674, #1675) by @jjstwerff in #1677
• Docs contract, compile-speed levers, and three lines joined — with the work-buffer interactions fixed by @jjstwerff in #1681
• @PLN166 compile speed (−47 % instructions), and loft2, loft3 and 157-native-4x joined by @jjstwerff in #1688
• @PLN166 and @PLN173 closed; loft2, loft3 and 157-native-4x joined (#1689–#1696) by @jjstwerff in #1702
• Red nightlies fixed through CI probes, #1706's use-after-free, cbor 0.1.7; loft2, loft3 and 157-native-4x joined (#1697–#1707) by @jjstwerff in #1709
• Shared generator holds, work-buffer pool, snapshot walks, foreign stores; loft2, loft3, 157-native-4x and the stability evaluation joined (#1697, #1708, #1710) by @jjstwerff in #1712
• Join: formal-rule fixes (#1715–#1729), foreign stores, C98, CI advisory issues by @jjstwerff in #1730
• Join of the active branches: C98 libraries, pattern-rule deviations, C91 content ==, the doc split, native perf, and a gate that resumes by @jjstwerff in #1744
• 2026.10 release candidate: 13 defect fixes, interpreter superinstructions, join tooling by @jjstwerff in #1763
• 2026.10 candidate fixes: #1773 crash, #1771, the placement leak, #1763's CI reds, and the ../loft + ../loft2 stability work by @jjstwerff in #1774

• 2026.10 release candidate: nine more fixes, every & link writes through, the #1816 cure guarded by @jjstwerff in #1838
• #1838's red checks: a keyed literal through a & parameter leaves the caller its own store; catalogue and doc lines by @jjstwerff in #1839
