Prism: decode gate, lineage journal and growth for AlgFormer models

Prism is the NuGet package that the Prism chat tool runs on. It holds three things for a model built on AlgFormer: the decode policy that chooses each next token, a lineage journal that records how the model grew, and a growth surface that changes the model and writes that record for you.

• One decode policy

  Commit greedily when the model is confident, otherwise sample only from what clears the floor. The gate is one tested policy with an explicit floor mode: a resonance floor for the holographic core, no floor, or nucleus sampling.

• Facts about the past stay facts

  Every structural change is stamped with the parameters a later calculation needs, when it happens. Questions such as how ramped a layer is, or when the model last grew, are answered from that history and never from whatever a live constant holds today.

• Growth that records itself

  Growing context, layers, shifts or vocabulary through the growth surface stamps the journal automatically, so a model cannot grow without the record.

• Lineage journal

  Idempotent append, so a resumed process stamping the same event again is a no-op. Derivations AlphaAt, DepthAt, LastGrowthRound and AddRoundOf resolve against the stamped history, including layers inserted at the front.

• Storage seam

  A file-backed JSONL store with durable append, and a pure in-memory store for browser and WebAssembly hosts that have no file system.

• Growth surface

  Grow a HoloFormer's context, layers, shifts or vocabulary, correct by construction, with the lineage stamped for you.

• Decode policy and gate

  DecodePolicy, Gate and GateDecision implement the confidence-gated decode with an explicit FloorMode.

• Degeneration guard

  DegenGuard fires on a run of repeated tokens or a run of non-greedy picks, the two signs that decoding has collapsed.
