+# EdgeBench Build Kits
+
+Self-contained, auditable build kits for rebuilding the **EdgeBench** task
+environment images from scratch on your own infrastructure — no access to any
+private registry or network required.
+
+Every released EdgeBench task image is exactly: **a public base image + a set
+of filesystem layers on top**. A kit ships that upper-layer content in an
+inspectable form, so a rebuild covers the same audit surface as a from-scratch
+build, while you audit the exact shipped bits rather than a build recipe that
+could drift from them.
+
+## Repository layout
+
+```
+bases/<key>/Dockerfile        # reference recipes for the language base images
+                              # (generated from EdgeBench tasks/BENCHMARK.yaml)
+kits/<task_id>/work/          # one kit per released image
+kits/<task_id>/judge/
+    Dockerfile                #   FROM <base tag> [+ RUN rm] + ADD context.tar + config replay
+    context.tar               #   merged filesystem diff above the base (ownership/modes preserved)
+    MANIFEST.sha256           #   per-file sha256 + mode + uid:gid + size — the audit anchor
+    kit.json                  #   provenance: source/base image IDs, layer digests, final image name
+build_from_kit.py             # standalone builder/verifier (python3 stdlib + docker CLI only)
+```
+
+Notes on the format:
+
+- `context.tar` is the **merged final view** of the task layers: files added
+  and later deleted by intermediate layers are collapsed away and never ship.
+- Layer whiteouts are materialized as `RUN rm` **only** when they delete files
+  that exist in the base image; the pilot kits are purely additive (no `RUN rm`).
+- `ADD context.tar /` preserves every file's owner, mode, and symlinks exactly
+  as recorded in the released image's layers.
+
+## Quick start (with the SForge harness)
+
+Base images build from public official images (`ubuntu:22.04`, `python:3.11`,
+`maven:3.9-eclipse-temurin-17`, ...). Base tags are deterministic — they hash
+the base definition in `tasks/BENCHMARK.yaml` — so a base you build yourself
+gets exactly the name each kit's `FROM` line expects.
+
+```bash
+# builds the base automatically, then work + judge from the kits,
+# then re-verifies every file against MANIFEST.sha256
+python -m sforge build --task ad_placement_optimization --kits-dir kits/ --verify
+python -m sforge run   --task ad_placement_optimization --agent ...
+```
+
+## Quick start (standalone, no harness)
+
+```bash
+# base (tag must match the kit Dockerfile's FROM line, see bases/)
+docker build -t edgebench.base.cpp:19685ea8d3f4 bases/cpp/
+
+# task images — the kit directory is the docker build context;
+# tag with kit.json's "final_name"
+docker build -t edgebench.work.ad_placement_optimization:49747cad3ebd \
+    kits/ad_placement_optimization/work
+docker build -t edgebench.judge.ad_placement_optimization:56cbfc81cfa1 \
+    kits/ad_placement_optimization/judge
+
+# optional: file-by-file verification against the manifest
+python3 build_from_kit.py --kit kits/ad_placement_optimization/work --verify
+```
+
+## Verifying the kits themselves
+
+Each `kit.json` records the source image ID the kit was derived from. To
+cross-check independently: pull the corresponding published EdgeBench image,
+compute its filesystem diff over the published base, and compare with
+`MANIFEST.sha256` — the manifests are reproducible byte-for-byte.
+
+## Current coverage
+
+Pilot batch (3 tasks / 6 kits): `ad_placement_optimization` (cpp),
+`k12_math_recommendation` (python), `exchange_core_throughput` (java).
+Remaining tasks will be added incrementally.

+Standalone version (python3 stdlib + docker CLI only, no sforge install needed).
+If you have the SForge repo set up, the integrated equivalent is:
+
+    python -m sforge build --task <task_id> --kits-dir <kits_root> [--verify]
+
+A kit directory (produced by export_task_kit.py) contains:

+
+Prerequisite: the base image named in the Dockerfile's FROM line already exists
+locally — build it from tasks/BENCHMARK.yaml with scripts/build_base_images.py.
+Base tags are deterministic, so a base built from the same BENCHMARK.yaml
+anywhere resolves the FROM line with no retagging.
+
+Usage:
+    python3 build_from_kit.py --kit kits/ad_placement_optimization/work --verify
+    python3 build_from_kit.py --kits-root kits --verify          # every */work, */judge
