v0.1.85

🚀 Release Highlights — v0.1.85 (2026-05-11)

⚠️ First-stage release — still maturing. Expect further finalization and more thorough end-to-end testing in v0.1.86.

🧪 Discriminative Criteria Emergence (criteria_mode)

• bootstrap_inline variant (fully functional): New orchestrator.coordination.criteria_mode: bootstrap_inline makes each agent emit a short proposed_criteria list alongside its submit_checklist call — criteria a stronger answer would satisfy that the current answers do not. Proposals are deduped, FIFO-capped (bootstrap_max_total, default 30), persisted to bootstrap_criteria_accumulator.json, and merged into the next round's checklist via the existing EvaluationSection
• All backends with checklist tool support: SDK path (Claude Code) gets the field directly in the in-process tool schema; stdio backends (gemini, codex, response, chat_completions, claude, grok) get a JSONL emission channel — proposed_criteria.jsonl next to checklist specs, drained by the orchestrator each pass
• bootstrap_subagent variant (wired, LLM step deferred): Same accumulator pipeline; in-process LLM discriminator pass queued for v0.1.86
• New module massgen/bootstrap_criteria.py with merge_proposals, augment_with_accumulator, is_bootstrap_mode, validate_criteria_mode
• Config fields: CoordinationConfig.{criteria_mode, bootstrap_max_per_agent_per_round, bootstrap_max_total}

🛡️ Anti-Goodhart by Construction

• Criteria come from observed gaps, not priors that may not match the task
• Removes cold-start friction: users no longer need to pre-author criteria for new tasks — the first round produces both answers and the criteria the second round must rise to

📦 New Example Configs

• massgen/configs/coordination/bootstrap_inline_criteria.yaml — fully functional variant
• massgen/configs/coordination/bootstrap_subagent_criteria.yaml — accumulator wired, LLM step in v0.1.86

🧪 Tests

• 30 new tests in massgen/tests/test_bootstrap_criteria.py (476 lines) covering merge/dedup/cap, config validation, AgentState.criteria_proposals, augmentation across criteria sources, rendering gating, and round-N → round-N+1 propagation end-to-end
