## Honest notes
- The v3 verdict for "Provider expansion" is PARITY (DIFFERENT COUNT) — Manual Slop has 8 providers per tech-stack.md (the qwen_llama_grok track adds 3 more); nagent v3 has 6 providers. The count is independent of the abstraction (per-model context windows, billing isolation, ground-truth harness).
- The v3.1 verdict for "Provider expansion" is PARITY (DIFFERENT COUNT) — Manual Slop has 8 providers per tech-stack.md (the qwen_llama_grok track adds 3 more); nagent v3.1 has 6 providers. The count is independent of the abstraction (per-model context windows, billing isolation, ground-truth harness).
- The "Conversation safety net" GAP is the highest-value v3 candidate — the 3-number config (`checkpoint_interval_minutes`, `checkpoint_max_new_kb`, `rebuild_at_kb`) + the sync-checkpoint invariant are concrete patterns Manual Slop can adopt.
- The "Case-study methodology" GAP is the methodology-level insight; the per-case-study sections (§10, §11) are the empirical evidence.
- v3 candidates are in `decisions.md`; the bridge doc is `nagent_takeaways_v3_20260619.md`.
- The "YAML avoidance" SUBSUMED is a "do not adopt" flag, not a "must not exist" ban. The user can still read and parse YAML (e.g., when reading nagent's source); the avoidance is for new Manual Slop artifacts.
- The "Agent context-window observations" GAP is the structural insight (warm-up + window + safe zone + cycle); the nagent `--hook-per-run` pattern is the structural mechanism that closes the gap.
- The "Fine-tuning observations" is observational, not a comparison. Vendor analysis is a separate future track.
- v3.1 candidates are in `decisions.md`; the bridge doc is `nagent_takeaways_v3_1_20260620.md`.
