`/quantus/runtime/152` — every pallet, call, event, error, storage entry and constant the runtime declares, with the constants' values decoded against their own declared types. Nothing transcribed from a source tree: a source tree says what the chain should be running, metadata says what it ran. The set of runtimes is found rather than waited for. Decoding caches one the moment it needs it, so left alone the cache is "whatever the backfill has walked past" — days on a chain a million blocks deep. `spec_version` only increases, so the boundaries are a sorted sequence and bisection finds each in log₂(height) probes. On Heisenberg that turned up six runtimes and the block each took over at: v126 from 1, v128 from 132, v131 from 342,813, v136 from 669,129, v144 from 812,055, v148 from 977,079 — two more than the four upgrade boundaries this approach was originally verified against. Discovery is its own task, not a poll step. `state_getRuntimeVersion` at an old block makes the node instantiate the runtime WASM from that block's state: ~4 s against Heisenberg's endpoint versus ~0.25 s at the tip, and a hundred of those inside a four-second loop stalls difficulty and the summary broadcast for minutes on every start. Reading Heisenberg's two ends side by side is the case for the page. Between v126 and v148 the chain dropped Referenda, ConvictionVoting, Recovery, Assets and AssetsHolder, added Vesting and Origins, gained `WeightReclaim` and moved `ChargeTransactionPayment` after the two Quantus-specific extensions. Every one breaks a decoder written against the other version and none is visible from a block. `U256`/`U512` now render as one decimal rather than four or eight little-endian limbs, identified by registry path exactly as `AccountId32` already was. Difficulty as `[1189189, 0, 0, 0, 0, 0, 0, 0]` describes the bytes correctly and tells a reader nothing. `ChainSummary` gained `spec_version`/`spec_name` so the footer can say what the site is decoding against, and link to it.
