llmtrim 0.10.2

Added

• Ordered model fallback for Claude Code /compact. Configure [compact] models = ["haiku", "sonnet"] or run llmtrim compact models haiku sonnet to try cheaper models for compaction.
  Each candidate is admitted against its known context window after candidate-specific compression;
  failures before any output advance to the next candidate, and Claude Code's selected model remains
  the implicit final fallback. The same chain works through subscription tier mappings, while
  preserving the original model identity in the response. llmtrim setup proposes the default
  chain on Claude Code installations that have not made a choice.
• llmtrim guard — stop paying for a cold cache without being told. Resume a session that has
  been idle past the prompt-cache TTL and the next turn silently re-writes the entire context,
  billed at the cache-write rate (2× base input for the 1h TTL Claude Code asks for). On a 225k
  context — the median across my own idle gaps — that is a few dollars before any work happens, and
  nothing at the prompt says so. guard is a Claude Code UserPromptSubmit hook: on the first
  submit after a long gap on a big context it prints the idle time, the context size and what the
  cold write costs, then exits 2, which blocks the prompt with no API call. A resend goes straight
  through, and the blocked message is saved to disk since Claude Code does not restore it. llmtrim setup offers to wire it in; guard install / guard uninstall do it directly, merging into
  ~/.claude/settings.json rather than clobbering hooks you already have. It reads Claude Code's
  transcript, not llmtrim's ledger — the ledger keys sessions by a hash of the system prompt, so a
  subagent turn would mask a stale main conversation — and every failure path exits 0: a bug in the
  guard must never block a prompt.

Changed

• The status line now refreshes while a session sits idle. It already reddened the cache segment
  once the prompt cache expired, but Claude Code only re-renders on conversation events, so an
  abandoned session kept the line drawn at its last turn — green and warm — straight through the TTL
  expiring. The warning only appeared after the turn that paid for it. It now sets
  refreshInterval, so the state is on screen before you type. Re-run llmtrim statusline install
  to pick it up.
• The cold-cache segment no longer suggests /compact. It read ♻ cold · /compact, which sold
  compaction as the thrifty move. It isn't: /compact re-reads the same cold context to summarise
  it — paying the charge it appears to avoid — and the next turn then writes a fresh cache for the
  summary. Resending pays once. The segment now just reports the state: ♻ cache cold.
