Implement Experiment 19: deterministic behaviour selector with five
behaviours (Acknowledge, Clarify, Summarise, Continue, Pause).
- lib/behaviour-selection/behaviour-selector.js — Pure function selector
applying v0.1 rules in priority order (acknowledge > clarify > summarise >
pause > continue). Defaults to Continue with low confidence when no rule
matches or assessment is incomplete. Guards against partial objects.
- tests/behaviour-selector.test.js — 51 tests covering all five behaviours,
priority ordering, contract conformance, determinism, edge cases, and
scenario-based validation with mock investigations.
- docs/design-evolution-log.md — Close Experiment 18 (record what assessor
enabled for Behaviour Selection), add Experiment 19 section with hypothesis,
scope, evaluation criteria, and open questions.
Passive integration only: no changes to reasoning engine, prompts, graph
generation, decomposition, narrative generation, API contracts, UI behaviour,
or Ollama integration.
