Module: PWN::AI::Agent::Curriculum

Defined in:: lib/pwn/ai/agent/curriculum.rb

Overview

PWN::AI::Agent::Curriculum is Tier 4/5 of the pwn-ai reinforcement loop — the SELF-PLAY layer that turns the agent from a passive experience-recorder into an active learner:

S1  .practice        — Mistake-driven auto-curriculum. Reads
                     Mistakes.top(unresolved), asks Reflect to
                     generate 3 minimal reproducer prompts per
                     signature, self-plays each under Loop.run,
                     and auto-mistakes_resolve when Reward.judge
                     says the practice run solved it. THE AGENT
                     PRACTISES ITS OWN WEAKNESSES OVERNIGHT.
S2  .counterfactual  — On a repeated in-turn failure, forks: branch
                     A continues with the correction_hint, branch
                     B asks an alt persona for a different tool.
                     Reward.judge picks the winner; (loser,
                     winner) → Reward.record_preference. Real
                     advantage estimation, not imagined rollouts.
S3  .critic          — Constitutional critic persona with TOOL
                     ACCESS (can shell/extro_verify the claim).
                     Runs BEFORE note_outcome; its verdict feeds
                     Reward.judge and its concrete flaw becomes a
                     preference pair when the agent self-corrects.
S4  .red_team_plan   — After plan_first, an adversarial persona
                     reviews the plan against THIS host's
                     Metrics/Mistakes/extro_drift and injects a
                     pre-emptive correction_hint on the step it
                     predicts will fail.
C3  .hindsight       — Hindsight Experience Replay. On failure,
                     asks the judge "what DID this trajectory
                     accomplish?", relabels the episode with the
                     achieved-goal as success:true. Free positive
                     samples from failures — first HER on real
                     tool traces.
W2  .train_and_gate  — export_finetune + export_dpo → local LoRA
                     (unsloth/axolotl if installed) → replay
                     Mistakes.top on vN vs vN+1 → promote iff
                     resolved(N+1) > resolved(N). Fully autonomous
                     weight-level self-improvement with a
                     regression gate.
W3  .calibrate       — Tracks plan_first predicted p(success) vs
                     actual outcome → Brier score in Metrics.

All entry points are cron-safe (never raise into the caller) and depth-guarded via Swarm's Thread.current so a curriculum run cannot recurse into itself.

COOLDOWN_FAIL_NIGHTS = Priority-fix 1 — N-night cooldown window for thrashing signatures and stale "needs_human" tags. Signatures that score ~0 for COOLDOWN_FAIL_NIGHTS consecutive practice nights are parked so the curriculum stops burning cycles on them.

.train_and_gate(opts = {}) ⇒ `Object`

Supported Method Parameters

Best-effort orchestrator. When a supported trainer is installed it produces ~/.pwn/finetune/pwn-vN/, cuts an ollama Modelfile with the LoRA adapter, then REPLAYS Mistakes.top against vN and vN+1 under Reward.judge. Promotes (writes MODELS_FILE) iff vN+1 resolves more signatures. When no trainer is present it still exports SFT+DPO and emits the exact CLI to run manually — so the pipeline is complete even on a box without GPU.
