    chore(release): 0.4.1

    swaits released this 2026-04-28 19:11:29 -06:00 | 16 commits to main since this release

    Bump workspace version 0.4.0 → 0.4.1.

    Patch release: dispatch hot-path performance only. No public API
    changes; every chart that compiled against 0.4.0 compiles unchanged
    and behaves identically. CHANGELOG.md captures the per-pass writeup
    under the 0.4.1 heading.

    Headlines (deepest dispatch in the bench suite):
    h8_cross_tree -82% instructions / -72% cycles vs pre_lca_fix
    bubble_top -22% instructions / -6% cycles vs handler walk
    terminate_event -22% instructions / -23% cycles vs PARENT walk

    The runtime LCA helper, is_up_transition, the per-call heapless::Vec
    ancestry build, the runtime PARENT bubble walk, and (on timer-free
    charts) the entire TimerTable machinery are all gone. Callgrind
    reports the entire HSM machinery as a single inlined step symbol.

    Bench suite expanded from 7 to 13 benches: bubble_leaf/mid/top
    quantify handler resolution at varying ancestor depths,
    timer_fire_dispatch covers the only path that exercises pop_expired's
    non-empty branch, terminate_event covers do_terminate, and
    bubble_cross_tree covers the realistic HSM worst case (deep bubble +
    deep cross-tree transition).
