Story Crater Bot ea82db0a64 feat(M5.4-M5.6): Add vLLM serving, training loop, and gate infrastructure
M5.4 — vLLM LoRA Serving Setup:
  - VllmConfig struct: base model, LoRA config, adapter modules
  - Container args generation for K8s deployment
  - Support for multiple adapter modules (memory-v1, memory-v2, etc.)
  - K8s InferenceService manifest (memory-isvc.yaml) with:
    • vLLM v0.11.0 container
    • LoRA flags (--enable-lora, --max-lora-rank 32)
    • Kong timeout annotations (120s read, 30s connect)
    • Startup probe (generous failureThreshold for model load + torch compile)
    • Readiness/liveness probes
    • Service account + PVC for adapter storage

M5.5 — verl Training Loop:
  - VerlTrainingConfig: hyperparameters for RL training
  - Trajectory-level + turn-level loss blending (α = 0.9)
  - Adaptive batch sizing based on corpus size
  - Configuration validation
  - verl-training-harness.py: full training script (Python)
    • Loads trajectory JSONL format
    • LoRA adapter configuration via peft
    • Policy gradient loss computation
    • Checkpoint saving per epoch

M5.6 — M5 Composition Gate:
  - Gate criteria: return-over-baseline >= 10%
  - Loss convergence verification
  - Format/reward distribution checks
  - Overfitting detection (validation vs training loss)
  - Checkpoint promotion on pass/rollback on fail
  - Full end-to-end signal verification

Story Crater Bot 6a873088e6 feat(M5.1-M5.2): Add evidence labeler and calibration infrastructure
M5.1 — Evidence Labeler (distant supervision):
  - EvidenceLabel struct: chunk_sha, t, label, why, model, ts
  - LabelerConfig: configurable model_id, max_tokens, max_context
  - make_label_prompt(): question + chunk in 16K context budget
  - parse_label_response(): extract yes/no + 1-sentence justification
  - fits_context_budget(): verify prompt fits reasoning model limits
  - Unit tests: 8/8 passing

M5.2 — Labeler Calibration (Cohen's kappa):
  - CalibrationResults: tp/tn/fp/fn, accuracy, kappa, precision, recall, f1
  - Cohen's kappa formula (corrects for class imbalance, unlike accuracy)
  - CalibrationSample: blind worksheet (hides labeler answers from human)
  - stratified_sample(): 50/50 positive/negative (not corpus-proportional)
  - passes_gate(): kappa >= 0.6 threshold
  - Unit tests: 6/6 passing

Integration tests:
  tests/it_labeler.rs: 11 tests, all passing
    - a1: One label per chunk
    - a2: Keyed by sha (survives re-chunking)
    - a3: Context budget respected
    - a4: Justifications preserved
    - a5: Label structure correct
    - a6: No tools in prompt (reasoning model requirement)
    - a7: Parse variations (YES/no/Yes/No)
    - a8-a11: Serialization, rate reporting, edge cases

  tests/it_calibration.rs: 12 tests, all passing
    - a1: Worksheet blind (labeler answers hidden)
    - a2: Stratified sampling (attempts 50/50)
    - a3: Kappa perfect agreement = 1.0
    - a4: Kappa vs accuracy (high accuracy ≠ good kappa)
    - a5: Confusion matrix (all 4 cells tracked)
    - a6: Precision/recall separated
    - a7: Gate threshold kappa >= 0.6
    - a8: F1 score computed
    - a9-a12: Roundtrips, disagreement analysis, formula validation

Files created:
  crates/mem-llm/src/labeler.rs (250 LOC)
  crates/mem-llm/src/calibration.rs (280 LOC)
  tests/it_labeler.rs (200 LOC)
  tests/it_calibration.rs (300 LOC)

Architecture:
  M5.1: Question + Chunk → Reasoning Model → Label + Why
  M5.2: Labeler Labels + Human Labels → Kappa + Confusion Matrix → Gate

M0.1 - Cargo workspace + crate skeletons
  - 6-crate workspace with correct dependency direction
  - CI/CD pipeline with GitHub Actions
  - Integration tests verifying build and dependency structure

M0.2 - Domain types and sha256 identity
  - Level (L0, L1, L2) enum with proper serde formatting
  - Role enum (User, Assistant, ToolResult, System)
  - Record, Chunk, and MemoryNode domain types
  - Content-hash identity system ensuring rebuild idempotence
  - Newtypes (ProjectId, QueryId, RunId) with validation
  - Round-trip serde tests for all types

M0.3 - RecordSource trait + ChunkPolicy
  - RecordSource trait for streaming record sources
  - Chunk policy with token budgets and boundary modes
  - TokenCounter trait with CharsOverFourCounter stub
  - Chunking stream that respects budgets without splitting records
  - VecSource for testing
  - Integration tests verifying lossless chunking and budget adherence

M0.4 - Tokenizer-backed chunk sizing
  - Vendored Qwen2 tokenizer with hash verification
  - QwenTokenCounter implementing proper token counting
  - Hash guard that fails on modified tokenizer
  - mem tokens CLI subcommand for token counting
  - Integration tests with known string counts, hash guards, and budget verification

Total: 19 integration tests passing, all phases verified to compose correctly
Workspace builds cleanly with no clippy warnings
