RTerm v3.9.4 — AI-Native Terminal App by Hyperspace Technologies

v3.9.4 (2026-09-24)

Three user-facing fixes: thread rename not sticking, Prev/Next user
navigation landing imprecisely, and a hardened no-regression pass over the
chat nav, mesh bridges, and neuralOS.

Thread rename didn't stick (root-caused + reproduced)

A rename arrives as a summary update with NOTHING new to append — all
messages are already persisted, so the flush calls
appendUiSessionMessages with fromPosition >= messages.length. The old
early-exit return 0 at that guard skipped the ui_sessions upsert
entirely, so the new title never reached SQLite; on the next load the
old title came back. Reproduced with a dedicated SQLite harness (rename a
2-message session, no-op append, read back: old title).

Fix: the summary upsert now ALWAYS runs inside the append transaction;
only the message-insert loop is conditional on there being new rows. A
no-summary no-op append preserves the existing title (no corruption);
an empty-messages append with a summary both upserts the title and
truncates stale rows. Regression-tested in the HistorySqliteStore.delta
spec (3 new cases, 10/10).

Prev/Next user landed imprecisely ("inconsistent", "doesn't work until

I switch threads")

The nav jump fired exactly ONCE per click (the v3.2.10 anti-scroll-trap
guard) — but a virtualized list only has MEASURED heights for rows that
have been rendered; a jump across many unrendered rows is computed from
ESTIMATED heights and lands short of or past the target, and the
once-only guard meant no later correction could fix it. Switching threads
remounted the list with a fresh measurement epoch, which is why it
"worked after visiting another chat".

Fix: the jump still applies immediately, then RE-APPLIES under a bounded
correction budget (6 passes max) as the target's neighbourhood renders
and real heights replace estimates, stopping the moment the computed
scrollTop converges. The budget is keyed to the version counter — a new
click resets it, layout-only updates drain it — and a user drag >40px
away cancels the loop outright, so the v3.2.10 scroll-trap can never
return (tested: a perpetually-drifting layout drains to zero). The
budget semantics live in a pure, unit-tested function
(nextUserNavCorrectionBudget, 4 new spec cases).

Also: the nav cursor now resets when a NEW user message is sent while
parked at the bottom (sending a follow-up is the natural "moving on"
signal — Prev previously kept walking from a stale anchor, which read as
"inconsistent"). Scrolled-up readers keep their cursor. Exposed
isNearBottom() on the ChatMessageList handle for this.

Mesh bridges + neuralOS audit (no latent bugs found; verified sound)

  • synapse/reactorpro bridge connections are POOLED by config key and
    reused (_conns), not leaked per call; failed connects evict the cache
    entry (retry-safe)
  • event subscriptions return proper stop-handles; no orphan intervals
  • the 180s dispatch → 170s invoke budget math is consistent across
    synapse-bridge, reactorpro-bridge, and the observability runner
    (hard cap 600s)
  • neuralos: engine executability (X_OK) enforced since v3.9.2; bridges
    write-gated (ALLOW_WRITES=False default); timeout plumbing verified
    end-to-end (execFile timeout + probe runner env)
  • the freeze family (MemorySaver checkpoint leak, bounded history
    search) was fixed in v3.8.9 and the guards (safeMemorySaver specs) are
    green in this release's chain — no remaining hang vectors found in the
    reviewed render/persistence paths (getPanelRect is a map lookup; no
    sync JSON deep-clones on the render path)

Tests: HistorySqliteStore.delta 10/10 (3 new), userMessageNav 8 cases
(4 new), v3210Fixes 8/8 (scroll-trap regression guard), chatPanel 9/9,
uiHistory suites (persistence 25, compaction 5, streaming 13,
renameRace 4), neuralos 51/51, synapse 6/6, reactorpro 52/52; full
layout-ui + backend-unit chains green; typecheck:all 0 errors.
