Makes blk_vm_flush_all() (block_words.c) non-static and declares it in block_words.h -- it's already the entire implementation behind SAVE-BUFFERS (block_word_save_buffers() is a one-line wrapper), so sk_repl_idle() can call the exact same flush path outside word dispatch without duplicating any logic. Cheap every idle tick regardless of dirty state: every check inside is a small fixed-size scan, so no separate pre-check was needed on top of it. Caught a real bug via a live persistence test before trusting the feature: the first version gated the flush on sk_repl_get_active_vm() returning non-NULL, but NULL is that accessor's documented default (Tripod's own USE-redirect override, "restore default dispatch") -- without an active USE redirect, the flush silently no-op'd for the entire session. Confirmed live: wrote a byte via BUFFER (no UPDATE/SAVE-BUFFERS), waited past the idle cadence, killed QEMU abruptly, rebooted with the same disk image, read back 0 instead of the written 65. Fixed by threading the VM sk_repl_run()'s own loop already resolves each iteration (g_repl_active_vm ? g_repl_active_vm : vm) down as a parameter through sk_readline() into sk_repl_idle(), rather than trying to re-derive it from an accessor with the wrong default. Re-ran the same test after the fix: read back 65, matching the written byte -- the write survived an abrupt kill with no explicit flush call anywhere in the test, proving the idle-tick auto-flush genuinely ran. All three architectures re-verified clean. FABRIC-2.md Section V item 6 and the corresponding Milestone 3 punch-list item marked done.
