🧠 Project rename — Prism MCP → Prism Coder

The project is now Prism Coder to reflect its full surface — the Mind Palace memory server and the open-weights LLM fleet (prism-coder:7b + prism-coder:14b on HuggingFace + Ollama).

The npm package stays published as prism-mcp-server so existing install URLs and mcp.json entries keep working without churn — but the prism-coder binary that package provides has been the canonical entry point since v12.

npm install -g prism-mcp-server@14.0.0
prism-coder

Algorithm-stability contract

The following exports are now stable public API under SemVer — external consumers can depend on the constants without re-implementing:

  • actrActivation.ts — baseLevelActivation, parameterizedSigmoid, compositeRetrievalScore, all ACT_R_* / DEFAULT_* constants
  • spreadingActivation.ts — applySpreadingActivation, the 0.7 / 0.3 hybrid score blend, the finalM = 7 cap
  • routerExperience.ts — getExperienceBias, MAX_BIAS_CAP = 0.15, MIN_SAMPLES = 5, the bias-scale formula
  • compactionHandler.ts — default threshold = 50, keep_recent = 10, MAX_ENTRIES_CHARS = 25_000
  • graphMetrics.ts — warning ratios 0.20 / 0.30 / 0.40 / 0.85 with their min-sample gates
  • config.ts — PRISM_ACTR_DECAY, PRISM_GRAPH_PRUNE_MIN_STRENGTH, full PRISM_GRAPH_PRUNE_* family

Breaking changes go through deprecation cycles announced in CHANGELOG.md.

Documentation

  • docs/WOW_FEATURES.md — citation-grade catalogue of Prism's algorithms with constants, semantics, and reuse patterns.
  • docs/releases/v14.0.0-prism-as-foundation.md — what the contract guarantees, why now, and the migration path for systems that have been re-implementing Prism algorithms.

Why a major bump

External systems were already building on Prism algorithms with hand-tuned approximations. Two failure modes when that happens: (1) the consumer's thresholds drift from Prism's over time, and (2) a copy-pasted constant loses its citation in 6 months and nobody remembers why 0.15 was chosen. Formalising the stability contract fixes both.

What's NOT in this release

  • No new MCP tools.
  • No model changes — prism-coder:7b and prism-coder:14b unchanged from v13.1.x.
  • No schema changes.

Tests

  • 71 test files / 2147 passing
  • Build clean
