The dsh-llm property-suite bullet claimed the suite checks an ordered-prefix
contract (the blocks push() returns incrementally are a prefix of final
blocks(), in order) and streaming-vs-one-shot agreement on usage/finish. Both
died with flushReady()/flushRemaining()/generate()/streamBlocks(): the
ordered-prefix guarantee was provided by that flush pair, and push() never
guaranteed it (index 0 opened by a delta then index 1 closed by block-end has
push() return block 1 while final blocks() orders [0, 1] — the returned block
is not a prefix).
Rewrite the bullet to enumerate only what properties.spec.ts actually asserts:
blocks() count <= distinct indices, idempotent re-assembly with message().content
mirroring blocks(), blocks() never throwing and yielding valid tags, and finish
reflecting the last finish chunk (defaulting to stop).
