# Document library — where to look

Use this map when you need a document outside the [current learning
session](learning-progress.md#next-session). The sidebar shows the primary
entrances; site search reaches the full retained corpus. Existing document
URLs and Markdown mirrors remain available.

## Learn and build

| Shelf | Use it for | Start here |
|---|---|---|
| Current course | The owner's 13-week inference route and its evidence contract | [Course workspace](learn.md), [weekly route](learn/inference-systems-13w.md) |
| One active task | Exercise, checkpoint, and actual delayed recall dates | [Next Session](learning-progress.md#next-session) |
| Foundations | Prerequisites from functions and tensors to attention and evals | [Ten-module curriculum](learn/curriculum.md), [ordered lessons](learn/README.md#i-want-to-learn-ml-from-scratch) |
| Practical labs | Runnable paths, artifacts, exercises, and mastery gates | [Artifact journey](learn/artifact-journey.md), [learning pipeline](learning-pipeline.md) |
| Model and systems concepts | Architecture, inference, training, and Mac-to-cluster boundary | [Learning index](learn/README.md#i-want-the-modern-llm-mechanics-reference), [Mac mastery map](learn/mac-mastery-map.md) |

## Apply and evaluate

| Shelf | Use it for | Start here |
|---|---|---|
| Factory contract | Target → data → post-training → eval → package → report | [Factory docs](factory/README.md) |
| Methods and recipes | Distinguish a technique from a runnable, gated recipe | [Technique registry](techniques/README.md), [recipe index](recipes/README.md) |
| CLI and integrations | Commands, local workflow, and external interfaces | [CLI reference](cli-reference.md), [integration example](integrations/model-run.md) |
| Data and models | Dataset provenance and retained model artifacts | [Data inventory](data_inventory.md), [model card](hf-cards/qwen3-4b-file-ops-distilled.md) |

## Inspect the evidence

| Shelf | Use it for | Start here |
|---|---|---|
| Outcomes | Final dispositions and failure explanations | [Attempt ledger](attempt-ledger.md), [public artifacts](factory/public-artifacts.md) |
| Performance | Measurements, harness design, and method limits | [Benchmark harness design](performance/benchmark_harness_design.md), [Mac decode baseline](research/mac_decode_baseline_m5pro.md) |
| Research | Benchmark and landscape findings, with sources | [Inference benchmark survey](research/inference_benchmarks_may_2026.md), [external products reviewed](external-products-reviewed.md) |
| Audits | Coverage and validation boundaries | [History coverage](audits/history-coverage-audit.md), [docs quality](audits/docs-quality-audit.md) |

## Read with historical context

| Shelf | Use it for | Start here |
|---|---|---|
| Status and admission | Closed-lab state and the rule for a fresh experiment | [Project status](https://github.com/PostTrainLLM/posttrainllm/blob/main/PROJECT_STATUS.md), [closure and next rule](NEXT.md) |
| Deferred specifications | Acceptance criteria for named historical or parked ideas | [PRD index](prds/README.md), [priority map](prds/PRIORITY.md) |
| Parked lanes | Work intentionally paused | [Parked lanes](parked/README.md) |
| Archive and session records | Historical plans, transcripts, and dated handoffs | [Archive status](archive/status.md), [document status registry](doc-status.md) |
| Original walkthrough | Python → WASM → WebGPU guided tour | [Legacy walkthrough](learn/legacy-walkthrough.md) |

Historical TODOs and PRDs are reference material. New model work still needs
an owner-selected question and the [fresh-experiment gate](NEXT.md).
