Merged to main. A stamp counts the issues a fix is linked to.

  • #113157 fix(compression): stalled summary route recovers on fallback_chain in the same turn; stall cooldown covers the idle window (#112387, #112420, salvage #112389, #112504)

  • #113813 fix(compression): repeated summary stall commits the deterministic fallback summary instead of looping (closes remaining atoms of #112420)
