LADDER — the epistemic ladder · doubts < believes < knows, a stronger rung supersedes · a demotion is refused, blocking, in the engine’s own words · shedding is deliberate: clearStance, eroded
§2.2's ordered ladder as an instrument: scrub and watch Marlow climb — doubts at the splash, believes at the dredging, knows when he holds it — each stronger rung superseding, the ghosts hollowed beneath the token · at the reckoning, gossip tries to demote his knowledge back to doubt and the grammar refuses: the blocking finding renders the engine's message verbatim (verb.setStance.ladder-demotion) and the rung stands · Elspeth's old doubt sheds the legal way — clearStance, disposition eroded, struck with provenance · Blunt's move re-told: Brody retracts his naming of the voice as a distinct proposition (its own rung) while the perceived belief stands unretracted and the old assumption sinks to a provenance facet — the ladder never trips · Tam's held knows and displayed believes ride parallel ladders that never cross-supersede · select a track to probe the grammar live: which arrivals land, which are BLOCKED, and the always-legal eroded shed
