libxtc (1.19.0-1) unstable; urgency=medium

  • Layering: fixed the L2->L3 upward dependencies and added a
    machine-enforced gate. The slab core is now a layer-neutral
    allocator (only _os*); its one proc-dependent convenience
    (xtc_slab_reaper_spawn) moved to src/ptc/slab_reaper.c, so the L2
    event loop's use of the slab for the per-loop timer objects is no
    longer an upward call. xtc_loop_fini's direct proc-table
    unregister became a hook (__xtc_loop_fini_hook) the L3 proc layer
    installs. New dist/s_layer lint (in make check + CI) forbids any
    .c from including a strictly-higher layer's header, with one
    documented XTC_LAYER_OK exception (io_net.c cooperative-wait).
  • Removed the L5 PostgreSQL adapter (milestone M16) from the plan:
    libxtc is a general-purpose async runtime (L0-L4) that ships the
    primitives, not a downstream adapter. PLAN.md and docs updated;
    PostgreSQL survives only as illustrative motivation.
  • Windows scalability fast path: the slab per-thread magazine is now
    backed by Fiber Local Storage (FlsAlloc) on Windows -- an FLS slot
    correctly follows a fiber across SwitchToFiber, unlike the
    __declspec(thread) static TLS that had to be disabled earlier.
    Win32 FLS API usage MinGW-verified; full MSVC re-measurement awaits
    a Windows host (EC2 benchmark parked; the Windows AFD socket-echo
    remains host-blocked, documented).
  • CI: added a FreeBSD job (vmactions/freebsd-vm, full gmake check) and
    a RISC-V 64 job (qemu-user cross-arch build + unit/property suites).
    Both also re-verified by hand this round (FreeBSD 15, RISC-V 64
    native). illumos-in-CI intentionally not added (no runner; nested
    QEMU too slow per commit) -- stays periodic manual re-verify.
  • No public xtc_* API change from 1.18.0.
